[0026] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a top view of the material conveying device 100 provided in the embodiments of this application. Figure 2This is a side view of the material conveying device 100 provided in an embodiment of this application. The material conveying device 100 includes a receiving bin 31 and a conveying pipe 10 as described in any embodiment of this application. The conveying pipe 10 is used to convey materials to the receiving bin 31. The materials include, but are not limited to, battery materials, food materials, pharmaceutical materials, fertilizer materials, and building materials, etc., and are not limited to any particular material here. For example, in an embodiment of this application, the conveying pipe 10 is used to convey battery materials, which are, for example, but not limited to, positive electrode materials, negative electrode materials, conductive agents, or dispersants; or, various materials are mixed to form a battery mixture.

[0027] Traditional material conveying pipelines are mostly made of metal. In the lithium battery industry, materials come into direct contact with the inner wall of the metal pipeline during transport. The inner wall of the metal pipeline is prone to wear, leading to the introduction of metal impurities into the material, including magnetic foreign objects. In subsequent processes such as pulping and coating, these introduced metal impurities can reduce battery performance, adversely affecting the quality of the batteries and their finished products, and even causing batch scrapping. Current technologies replace metal pipelines with non-metallic pipelines. While non-metallic pipelines avoid metal contamination, the friction between the material and the non-metallic pipeline generates electrical charges. These charges accumulate and can lead to electrostatic discharge. When transporting flammable or explosive materials, the released static electricity can easily trigger pipeline explosions and other safety accidents, threatening production safety and normal equipment operation.

[0028] Please refer to the following: Figure 1 , Figure 2 and Figure 3 , Figure 3 This is a cross-sectional view of the conveying pipe 10 provided in an embodiment of this application. In this embodiment, the conveying pipe 10 includes at least one pipe section 11, a first conductive structure 12, a second conductive structure 13, and a grounding connector 141. Each pipe section 11 is provided with a conveying channel 101 for conveying materials. The first conductive structure 12 is disposed on the inner sidewall 111 of at least one pipe section 11. The second conductive structure 13 is disposed on the outer sidewall 112 of at least one pipe section 11 and is conductively connected to the first conductive structure 12. The grounding connector 141 is conductively connected between the second conductive structure 13 and the grounding terminal 142. When conveying materials, the conveying pipe 10 in this embodiment can conduct the charge to the grounding terminal 142 in a timely manner through the first conductive structure 12, the second conductive structure 13, and the grounding connector 141, thereby preventing the accumulation of charge on the pipe section 11, thus avoiding the generation of static electricity and improving the safety of material conveying.

[0029] For example, in this embodiment, the pipe body 11 is a non-metallic pipe body. Specifically, the pipe body 11 is a conductive non-metallic pipe body. When transporting materials, the conveying pipe 10 transports the materials entirely within the non-metallic pipe, completely eliminating the risk of introducing magnetic foreign objects due to contact between the materials and the metal pipe during the transfer process. This ensures that the materials in lithium battery production maintain high purity, improves the quality and performance of the produced lithium battery products, meets the stringent requirements of the new energy lithium battery industry for the purity standards of raw materials, and allows the accumulated charge to be discharged in a timely manner through the conductive path formed by the first conductive structure 12, the conductive non-metallic pipe body, the second conductive structure 13, the grounding connector 141, and the grounding terminal 142. This solves the safety hazard of static electricity accumulation when transporting materials through non-metallic pipes, ensures the safety and stability of the production process, avoids safety accidents caused by static electricity, and ensures production safety and normal operation of equipment.

[0030] The conductive non-metallic tube can be made by doping a conductive material into a non-metallic material. The conductive material provides conductivity to the non-metallic tube, allowing charge to be conducted to the second conductive structure 13. The non-metallic material can be high-density polyethylene, rigid polyvinyl chloride, polypropylene, or other non-metallic materials with high strength, high molecular weight, high wear resistance, and good corrosion resistance to improve the service life and reliability of the tube 11. For example, the non-metallic material can be polypropylene, which has strong chemical corrosion resistance. Other materials can also be selected based on factors such as working conditions and process requirements; this application does not impose specific limitations. The conductive material is a non-metallic material. The conductive material can be specifically selected based on factors such as working conditions and process requirements; this application does not impose specific limitations. For example, the conductive material can be carbon black, carbon fiber, carbon nanotubes, or other materials with conductive capabilities. When preparing the tube 11, the non-metallic material and the conductive material can be mixed evenly and then manufactured using a pipe extrusion device or other equipment. Exemplarily, the tube 11 can be a conductive polyethylene tube, a conductive polyvinyl chloride tube, or a conductive polypropylene tube. The inner wall of the pipe body 11 is smooth to reduce the frictional resistance between the material and the inner wall of the pipe body 11 during the conveying process, thereby reducing the wear of the pipe body 11 and extending its service life.

[0031] The first conductive structure 12 and the second conductive structure 13 are electrically connected to the conductive non-metallic tube body, respectively, and are electrically connected to each other through the conductive non-metallic tube body. When the material generates charge due to mutual friction with the tube body 11 and the first conductive structure 12, the generated charge will be conducted to the grounding terminal 142 through the electrostatic discharge circuit formed by the first conductive structure 12, the conductive non-metallic tube body, the second conductive structure 13 and the grounding connector 141, thereby preventing charge from accumulating in the conveying pipe 10 and avoiding the generation of static electricity.

[0032] Please see Figure 4 , Figure 4This is a cross-sectional view of a conveying pipe 10 provided in some embodiments of this application. In some embodiments, the conveying pipe 10 further includes a conductive connector 15. A clearance hole 102 is provided on the pipe body 11. The conductive connector 15 passes through the clearance hole 102 and is conductively connected to the first conductive structure 12 and the second conductive structure 13, respectively. When the pipe body 11 conveys materials, the charge generated during the conveying process is conducted sequentially through the first conductive structure 12, the conductive connector 15, the second conductive structure 13, and the grounding connector 141 to the grounding end 142, thereby preventing charge accumulation in the conveying pipe 10 and preventing the generation of static electricity. The conductive connector 15 is sealed to the pipe body 11, and the conductive connector 15 seals the clearance hole 102 to prevent material leakage from the clearance hole 102. The conductive connector 15 and the pipe body 11 can be fixedly connected by means of welding, bonding, etc. The conductive connector 15 can be configured as a metal column or a non-metallic conductive column.

[0033] In some embodiments, a single conductive connector 15 may be used. In other embodiments, multiple conductive connectors 15 may be used, with the multiple conductive connectors 15 arranged at equal or unequal intervals along the circumferential direction of the tube body 11; or, the multiple conductive connectors 15 arranged at equal or unequal intervals along the axial direction of the tube body 11; or, a portion of the multiple conductive connectors 15 are arranged at equal or unequal intervals along the circumferential direction of the tube body 11, while another portion of the multiple conductive connectors 15 are arranged at equal or unequal intervals along the axial direction of the tube body 11. The specific arrangement of the multiple conductive connectors 15 can be specifically set according to actual needs, and is not specifically limited in this application.

[0034] Please see Figure 3 In some embodiments, the first conductive structure 12 is attached to the inner wall 111 of the tube body 11. In some embodiments, the first conductive structure 12 and the tube body 11 can be integrally formed. In some embodiments, the first conductive structure 12 and the tube body 11 can also be independently arranged, and the first conductive structure 12 and the tube body 11 can be fixed together by means of bonding, welding or other methods.

[0035] The first conductive structure 12 is a non-metallic conductive structure. The non-metallic conductive structure includes at least one of a conductive fiber mesh, a conductive layer, and a conductive strip. In some embodiments, the first conductive structure 12 can be configured as a conductive fiber mesh. The conductive fiber mesh can be a mesh structure formed by conductive limiting and spreading it on the inner wall 111 of the tube body 11. The conductive fiber mesh is fixed together by bonding, welding, or other methods, or the conductive fiber mesh and the tube body 11 can be integrally formed. In some embodiments, the non-metallic conductive structure can be configured as a conductive layer. The conductive layer can be a slurry formed on the inner wall 111 of the tube body 11 by coating and then drying, or the conductive layer can be conductive powder spread on the inner wall 111 of the tube body 11, and the conductive powder can be fixed together with the tube body 11 by bonding, welding, or other methods. In some embodiments, the conductive strip is a strip structure, and the conductive strip can be wound onto the inner wall 111.

[0036] In some embodiments, when the conveying pipe 10 is used to convey materials that have strict requirements for metal foreign objects, the first conductive structure 12 can also be configured as a metal conductive mesh to improve the conductivity of the first conductive structure 12, reduce the difficulty of setting the first conductive structure 12, and reduce the production cost of the conveying pipe 10.

[0037] Please see Figure 5 , Figure 5 This is a cross-sectional view of the conveying pipe 10 provided in some other embodiments of this application. In some embodiments, a conductive layer 16 is affixed to the outer wall 112 of the pipe body 11. A second conductive structure 13 is disposed on the side of the conductive layer 16 away from the pipe body 11 and is conductively connected to the conductive layer 16. The conductive layer 16 is affixed to the pipe body 11. In the embodiments of this application, on the one hand, the conductive layer 16 can increase the contact area with the pipe body 11 and reduce the contact resistance, so as to transfer charge more quickly, thereby improving the conductivity between the second conductive structure 13 and the pipe body 11 and avoiding charge accumulation in the pipe body 11. On the other hand, by setting the conductive layer 16, it is also possible to avoid making the entire pipe body 11 using conductive materials, thereby reducing the production cost of the pipe body 11. The conductivity of the conductive layer 16 can be greater than the conductivity of the pipe body 11. The conductive layer 16 can be made of metallic conductive materials or non-metallic conductive materials. For example, the conductive layer 16 can be a tin-plated layer, a zinc-plated layer, a graphite layer, a carbon fiber layer, etc.

[0038] In some embodiments, the conductive layer 16 may be configured as a coating, and the conductive layer 16 is fixed to the outer wall 112 of the tube body 11 by coating. In some embodiments, the conductive layer 16 and the tube body 11 may also be a separate structure, with the conductive layer 16 covering the tube body 11.

[0039] In some embodiments, the first conductive structure 12 and the conductive layer 16 are disposed opposite each other along the radial direction X of the tube body 11. This reduces the creepage distance between the first conductive structure 12 and the conductive layer 16, reduces the charge transmission distance in the tube body 11, and facilitates the smooth and rapid transmission of charge from the first conductive structure 12 to the conductive layer 16.

[0040] In some embodiments, along the axial direction of the pipe body 11, the lengths of the first conductive structure 12, the second conductive structure 13, and the conductive layer 16 can be less than the length of the pipe body 11, meaning the first conductive structure 12 and the second conductive structure 13 do not necessarily need to cover the entire pipe body 11, thereby reducing the manufacturing cost of the conveying pipe 10 while eliminating static electricity. In some embodiments, along the axial direction of the pipe body 11, the lengths of the first conductive structure 12, the second conductive structure 13, and the conductive layer 16 can be equal to the length of the pipe body 11. The conductive layer 16 can completely cover the outer wall of the conveying pipe 10, and the conductive layer 16 is continuous and complete to ensure that static electricity can be promptly discharged to the grounding terminal 142.

[0041] Please refer to the following: Figure 1 , Figure 2 and Figure 3 In some embodiments, the conveying pipeline 10 also includes a non-metallic joint 17. The pipe body 11 is configured as multiple sections. Adjacent pipe body sections 11 are connected by a non-metallic joint 17. In this way, the arrangement of the multiple pipe body sections 11 can be flexibly adjusted through the non-metallic joint 17, so that the shape of the conveying pipeline 10 can adapt to different scenario requirements. The non-metallic joint 17 can be configured as a clamp-type joint or a flange-type joint to simplify the structure of the non-metallic joint 17, facilitate the installation and maintenance of the conveying pipeline 10, and ensure that the connection strength between the non-metallic joint 17 and the pipe body 11 is high, which can ensure that the conveying pipeline 10 has good sealing and firmness after connection, so that the conveying pipeline 10 can withstand the conveying pressure of materials, avoid pipeline breakage and damage, and ensure the stable operation of the pipeline system.

[0042] In some embodiments, the second conductive structure 13 is disposed at the connection between two adjacent pipe sections 11. Thus, a single second conductive structure 13 can simultaneously conduct electricity to both adjacent pipe sections 11, thereby reducing the number of second conductive structures 13 and reducing the manufacturing cost of the conveying pipe 10. Alternatively, the second conductive structure 13 can be disposed on the non-metallic joint 17. The second conductive structure 13 covers the non-metallic joint 17 and is electrically connected to the two adjacent pipe sections 11.

[0043] In this embodiment, one part of the multi-section pipe 11 is a straight pipe, and the other part of the multi-section pipe 11 is a bent pipe. The straight pipe extends in a straight line. The bent pipe extends in a bent manner. In this way, the straight and bent pipes allow the shape of the conveying pipe 10 to be flexibly adjusted according to the space constraints in different installation scenarios, reducing the installation difficulty of the conveying pipe 10.

[0044] The second conductive structure 13 is disposed on a straight pipe to reduce the difficulty of installing the second conductive structure 13. In some embodiments, the second conductive structure 13 may be disposed on a bent pipe.

[0045] For example, the second conductive structure 13 is configured as a metal mesh, which is tightly fitted to the outer wall 112 of the tube body 11. The metal mesh is elastic, which facilitates storage and reduces the transportation cost of the second conductive structure 13. Furthermore, it can elastically deform during installation to adapt to different installation locations and space constraints, reducing the installation difficulty of the second conductive structure 13. The second conductive structure 13 can be configured as a stainless steel wire mesh to prevent corrosion and extend its service life. In some embodiments, the second conductive structure 13 can also be configured as a mesh made of other metal materials, such as copper wire mesh or aluminum wire mesh.

[0046] The material conveying equipment 100 also includes a frame 20. The frame 20 includes multiple support columns 21 and multiple crossbeams 22. The multiple crossbeams 22 are connected to form a support platform. The multiple support columns 21 are respectively connected to the support platform. A receiving bin 31 is installed on the support platform. In some embodiments, a grounding terminal 142 is disposed on the frame 20 and electrically connected to the ground to conduct charge to the ground. In some embodiments, the frame 20 is configured as a grounding terminal 142, the support columns 21 are electrically connected to the ground, the crossbeams 22 are electrically connected to the support columns 21, and the grounding connector 141 is electrically connected to the support columns 21 and / or the crossbeams 22. The grounding connector 141 can be configured as a conductor to improve the layout flexibility of the grounding connector 141 and avoid interference with other structures of the material conveying equipment 100.

[0047] In some embodiments, the material conveying device 100 further includes an air extraction device 32. The air extraction device 32 is connected to the receiving chamber 31. The conveying pipe 10 is connected to the receiving chamber 31. The air extraction device 32 is used to extract gas from the receiving chamber 31, creating a negative pressure inside the receiving chamber 31, thereby creating a negative pressure inside the conveying pipe 10. The material is then conveyed along the conveying pipe 10 under atmospheric pressure. Alternatively, the air extraction device 32 can also be used to blow air into the receiving chamber 31, creating a positive pressure inside the receiving chamber 31, thereby pushing the material through the positive pressure in the conveying pipe 10. The air extraction device 32 can be configured as a Roots blower. One end of the conveying pipe 10 is connected to the receiving chamber 31, and the other end of the conveying pipe 10 is connected to a material bag. The negative pressure generated by the Roots blower draws the material into the receiving chamber 31. A weighing sensor can be installed on the receiving chamber 31 to accurately calculate the weight of the material being drawn in. In this embodiment, the pipe body 11 of the conveying pipe 10 is configured as a conductive non-metallic pipe body, which can significantly reduce the material cost of the conveying pipe 10 while ensuring that the conveying pipe 10 performs its normal material conveying function, thereby reducing the manufacturing cost of the material conveying equipment 100.

[0048] In some embodiments, the material conveying device 100 further includes a flow meter 33. The flow meter 33 is disposed on the conveying pipe 10 and is used to detect the flow rate of the material in the conveying pipe 10.

[0049] In some embodiments, the material conveying equipment 100 further includes guardrails 23 and stairs 24. The stairs 24 are connected to the frame 20 to facilitate workers climbing to the support platform for work. Guardrails 23 are provided at the four edges of the stairs 24 and the four edges of the frame 20 to ensure the safety of workers moving on the stairs 24 and the frame 20 and to prevent workers from falling.

[0050] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
