Application of hydraulic screening bucket in backfilling of sieving soil pipeline fine soil

With the rapid economic development, the construction of underground pipe corridors has been fully rolled out. Whether many petrochemical pipelines can be operated safely and normally has put strict requirements on pipeline construction. Due to the large reduction of cultivated land and severe damage to environmental vegetation, the original backfilling method used for pipeline construction in special pipeline sections has been unable to meet the various construction requirements at this stage. Construction that fails to meet the standards will even leave many hidden dangers for the later management of pipeline construction .

Therefore, strict backfill standards for fine soils came into being. First of all, it is required to be backfilled with fine soil within 300mm above the top of the pipe. The maximum particle size of fine soil cannot exceed 10mm. Then, the backfilled earthwork should not contain frozen soil, garbage, wood and soft materials. The maximum particle size of gravel in earthwork should not exceed 250mm, and it cannot destroy cultivated fields and vegetation.

The invention of the multifunctional hydraulic screening bucket solved many problems in pipeline backfilling. The multifunctional screening and crushing bucket is assembled on the excavator on site, and the power of the excavator is used to complete the soil extraction, mixing, crushing and screening in one step at the construction site. This approach greatly reduces the process, saves time, improves the uniformity and fineness of crushing and screening, and reduces investment and operating costs. Because the crushing and screening are concentrated in one place, it is close to the semi-closed crushing and screening operation, which greatly reduces the environmental pollution along the construction line. Make the pipeline construction results easily meet the strict requirements of pipeline construction.

Screening buckets have been field tested by pipeline specialization companies in some pipeline projects and adopted in some engineering constructions. The working efficiency of the hydraulic screening bucket meets the requirements of the pipeline construction for the thickness of the fine soil at the top and bottom of the pipe and the particle size of the backfill soil, ensuring the quality of the project while reducing the damage to the cultivated land, environment and vegetation during the construction, and saving the single fund 50% of the investment has been fully affirmed by users.

It is precisely because of the lightness and dexterity of the hydraulic screening bucket, and it has the functions of screening, crushing and shoveling. The working efficiency of a 20T excavator is generally 60-100m3 / h, and its comprehensive working efficiency is compared with other pipelines on the market The construction of fine soil backfill equipment is much higher.

The crushing screening bucket is basically not limited by the construction site, and has high working efficiency, easy installation, easy operation, small size, convenient transportation, low use cost, and plays an important role in pipeline construction.

Where does 3D Printing stand in this digital transformation?

Considering the nature of traditional manufacturing, which is based on centralized mass production, 3D printing can make a big difference for companies trying to move into industry 4.0.
Together with the IIoT or Industrial Internet of Things, Big Data and other technological developments, 3D printing, also known as additive manufacturing, can be considered part of a complex framework for industry 4.0. Moreover, if we consider the benefits that additive manufacturing can provide to industries such as automotive, consumer electronics and medical, there is no doubt that 3D printing fits into industry 4.0 perfectly. Some of these benefits include, but are not limited to:
3D Printing Prototype
• Higher prototyping speeds: with the development of 3D printing technologies and materials, companies can have a prototype in minutes, making it easier to test different designs in short periods of time.
• Higher customization: thanks to the speed of current 3D printers, and the fact that only one machine is needed for the whole manufacturing process and materials are cheaper, mass customization is possible. This is an aspect that had been lost in many industries due to the utilization of mass production in order to reduce costs, and it is of great importance for the medical industry to manufacture prosthetics and other very personal products.
3D Printing Prototype
• Outsourced and onsite manufacturing: while many big companies may find 3D printing an affordable investment to have their own products, tools or spare parts manufactured onsite, smaller companies and even individuals may find some limitations. However, 3D printing prototype service providers can make it more affordable for those requiring a more “on-demand” alternative to cover the needs of specific projects.

ADVANTAGES OF METAL LASER CUTTING MACHINE IN PLASTIC PROCESSING

The latest plastic processing can be processed with metal laser cutting machines. The laser cutting machine focuses the laser beam on the surface of the plastic material, uses the high-temperature characteristics of the laser to melt the material, and makes the laser beam and the plastic product run along a certain trajectory to obtain the ideal plastic product.

When it comes to plastic products, many people think of barrels, baskets, pots, etc. sold by street vendors. With the development of science and technology, plastic products are not just the above products. They are used in automobiles, electronics, and medical equipment, and even include aerospace high-tech, precision, and cutting-edge fields. However, to be applied in these high-end fields, in addition to the material of the plastic itself must meet the requirements of laser cutting processing, the problem of laser lettering processing must also be solved, and how to achieve the precision of plastics during welding, cutting, engraving, drilling, etc. , Clean, fast, efficient issues.

Laser cutting machine has the following advantages:
First, the quality of the plastic nozzle of the laser cutting machine is good, which belongs to non-contact cutting. The cutting edge is affected by heat very little, there is almost no thermal deformation of the workpiece, the slump formed during die punching is completely avoided, and the laser cutting seam is smooth and flat.

Second, laser cutting machine processing plastic materials can increase the speed of new product development. After the product drawing is formed, laser processing can be performed immediately, and samples of new plastic products can be obtained in the shortest production cycle.

Third, the laser cutting machine can cut plastic materials, which can save the cost of plastic molds. Plastic laser cutting does not require molds, no mold consumption, no need to repair molds, saving mold replacement time, thereby saving processing costs, reducing manufacturing costs, and suitable for large Processing of small products or small batches of plastic products.

Plastic is widely used and is an indispensable component in home appliances, automobiles, mobile phones, PCs, medical equipment, and lighting appliances, so the processing and application of plastic is also essential.

Using a co2 carbon laser engraving machine to engraving advertising crystal is undoubtedly the best. The choice is to use a laser engraving machine to sculpt one time without additional polishing. Laser cutting machine is used for cutting plastic materials. When processing plastics, the traditional mechanical processing method is to directly apply machinery such as drills to plastic workpieces, which will cause plastic deformation uniformly, and will also cause burrs at the processing place. In order to meet the production requirements, some processing is required, and the processing speed is It will be slower and less precise. However, the use of laser cutting can avoid the above disadvantages, greatly speeding up the research and development of new plastic products, and also accelerate the application of plastics in high-end fields.

The advantage of metal cloisonne pins

Metal cloisonne pins is one of China's famous special metal crafts. This kind of craftsmanship reached its peak at the Jingtai period of the Ming Dynasty. The crafts produced were the most exquisite and famous, so later people called this porcelain "Chengtailan". Cloisonné is a kind of porcelain utensils made of copper on the copper type, which is made of soft flat copper wire, which is welded into various patterns and then filled with enamel color glaze. Because of its prevalence in the Ming Dynasty, the production techniques are relatively mature, and the enamel glaze used is mostly blue, hence the name "Jingtai Blue".
The advantages of cloisonne craftsmanship in jewelry design are individualized and diversified with the jewellery elements. As a special material for surface decoration, cloisonne is widely used in the art field due to its own advantages.
(a) colorful
The cloisonne craftsmanship varies in color, and the jewellery works can achieve a satisfactory color combination regardless of the sense of the picture. For Makong jewelry, the color Wei Li is the primary feature, but the color of the gem itself is limited, and it needs to be matched with the same color gemstone, but many gemstones are too expensive. The cloisonne process can make up for this shortcoming in jewellery applications. The glass is rich in color and the color is ever-changing. The pigment can be used to match the ideal color. It is like a household palette, as long as it is a short-sighted color of the naked eye. It can be obtained by fine material blending.
(two) changeable
In jewelry design, the higher the designer's freedom, the more diverse the design, the more jewellery design style can be displayed. The cloisonné process is designed to allow the designer to create a chapter, and it is not necessary to design the jewelry shape to create a gem setting. When the beads are taken into the box, the liquid is filled, and the amber and the color material can fully fill the space, so that the chamber stone can be inlaid in a seamless manner, and the shape and structure of the jewelry embryo itself are not necessarily confused, and the design freedom is high.
(3) Simple process
In the jewellery design, the cloisonne is simple in craftsmanship. A sling or ring can be shaped like a plasticine image. After a simple pressure, it can become a precious metal jewellery, just like a net change. You can buy curious things through your own hands.
(4) Low cost inspection
For a product, the input and output ratio should be considered in the production of the product. People are more willing to get twice the result with half the effort at a reasonable cost. The jewelry design is no exception. Compared with the paving process, the box material is mostly derived from the glass knot. Compared with the empty stone material, the shaft material is also excellent in gloss and durable in material, but the cost is low, powder and material. As long as a small amount can be formulated with the most liquid and unique material.
(5) Color durability
Natural, beautiful, rare, and durable are the essential qualities of the gemstone. The texture is as durable as the gemstone in the material, mainly reflected in:
1. Hardness; now is a shaft-based inorganic mineral, feldspar, quartz, oxidized metal, etc. as the main component, excellent hardness. In the cloisonne needle, the inorganic substance is measured and mixed into a powdery method. After filling it into the metal, it is burnt in the 800-degree high-humidity furnace. The cloisonne can be firmly burned with the metal, and the color The old bright dance gun, after the release of the collar is a beaded product. The hardness of cloisonne products is 7, close to the need for green, crystal, the surface has a cold luster, the texture is hard, can accept the test of acupuncture and knife.
2. Texture cigarette smoker: During the gem setting process, there will be silver-inlaid gaps. This gap will not only be often obscured, but also troublesome and easy to appear. For gemstone embedding, it is very difficult to seamlessly combine two different substances, but the cloisonne process can solve this problem. In this process, the metal body can be compared with the finished product and the layer is tight. Without seams, the multi-layered material also ensures a smooth surface.
3. High temperature resistance and corrosion resistance: The physicochemical properties of cloisonne are constant, high corrosion resistance, and no damage at high temperatures.
