Description

Technical Field

[0001] This utility model relates to the field of conveyor chain technology, specifically a high-efficiency and durable conveyor chain for municipal waste incineration. Background Technology

[0002] Municipal solid waste incineration is an important waste treatment method. It refers to the treatment of waste generated in daily urban life through high-temperature incineration, which significantly reduces its volume and weight and converts it into other forms of energy such as heat and electricity. At the same time, it achieves harmlessness, volume reduction and partial resource recovery. In the waste incineration process, the waste is first collected and transported to a dedicated waste-to-energy plant or treatment plant through various means. In this series of processes, the conveyor chain plays a crucial role.

[0003] Patent document CN207174680U discloses a linear conveyor chain, which states that "this utility model includes several chain units connected in sequence. Each chain unit includes rollers, outer chain plates, and inner chain plates, all of which are rotatably connected to pins. It also includes a vertically extending frame for clamping the transported goods, positioned between and connected to the chain units. This utility model, with its frame for clamping the transported goods, can fix the position of the goods during transport, preventing lighter goods from detaching from the conveyor chain or slipping, thus ensuring a smooth and efficient transport process. Furthermore, this utility model has advantages such as low friction between components, meeting the transport requirements of different goods."

[0004] However, the linear conveyor chain described in the aforementioned published literature mainly considers the advantages of low friction between components and the ability to meet the conveying needs of different goods, but it is not convenient to increase the chain's high-temperature resistance, reduce thermal creep, and improve its service life.

[0005] In view of this, it is necessary to develop a performance mechanism that can increase the chain's high-temperature resistance, reduce thermal creep, and improve its service life. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency and durable municipal solid waste incineration conveyor chain to solve the technical problem of improving the performance of the high-efficiency and durable municipal solid waste incineration conveyor chain mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and durable municipal waste incineration conveyor chain, comprising: an outer chain plate, a middle chain plate, and a pin shaft, wherein the inner wall of the middle chain plate is provided with a performance mechanism, which is used to increase the chain's high temperature resistance, reduce thermal creep, and improve its service life;

[0008] The performance mechanism includes a stainless steel wear-resistant sleeve, a mounting plate, and an assembly screw groove. The stainless steel wear-resistant sleeve is located on the inner wall of the connecting hole, and the mounting plate is located on the outer wall of the stainless steel wear-resistant sleeve. The outer wall of the middle chain link has a splicing screw groove, and the outer wall of the mounting plate is equipped with a splicing screw, with one end of the splicing screw extending into the interior of the splicing screw groove. The outer wall of the outer chain link has a matching groove, with one end of the matching groove extending into the interior of the pin hole. The outer wall of the stainless steel wear-resistant sleeve has an assembly screw groove, and the outer wall of the middle chain link has an operating groove. The inner wall of the operating groove is equipped with a threaded plate, and the inner wall of the threaded plate is equipped with an assembly screw, with one end of the assembly screw penetrating through the interior of the threaded plate and located inside the assembly screw groove.

[0009] Preferably, a chain plate is installed on the top of the outer chain piece, the middle chain piece is located on the outer wall of the outer chain piece, the inner wall of the outer chain piece is provided with a pin hole, the inner wall of the pin hole is provided with a pin shaft, and the inner wall of the middle chain piece is provided with a connecting hole.

[0010] Preferably, the outer wall of the chain plate is provided with a lubrication mechanism, which is used to facilitate lubrication of the sprocket and reduce chain wear.

[0011] Preferably, the lubrication mechanism includes an oil reservoir, an oil outlet, and a contact rod, with the oil reservoir located on the top of the chain plate.

[0012] Preferably, the inner walls of the oil storage tank and the oil outlet are both equipped with sealing screw rings, the inner walls of the sealing screw rings are provided with sealing threaded top covers, the inner walls of the oil storage tank are equipped with limit rods, the outer walls of the limit rods are surrounded by sliders, the outer walls of the sliders are equipped with touch rods, the outer walls of the touch rods are equipped with touch blocks, and the touch blocks are located below the chain plate.

[0013] Preferably, a sealing block is installed on the outer wall of the touch rod, a plate is installed on the inner wall of the oil storage tank, a spring is installed on the outer wall of the plate, one end of the spring extends to the outer wall of the touch rod, and the sealing block is located above the oil outlet.

[0014] Preferably, the bottom of the chain plate is provided with an oil outlet hole, and one end of the oil outlet hole extends into the interior of the oil storage tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model increases the chain's high-temperature resistance, reduces thermal creep, and extends its service life by installing a performance mechanism. First, the stainless steel wear-resistant sleeve is moved into the connecting hole. Then, the assembly screw is rotated to move within the threaded plate, moving one end of the assembly screw into the assembly screw groove, thus fixing one end of the stainless steel wear-resistant sleeve. Subsequently, the other end is fixed into the splicing screw groove by the splicing screw, thus stably fixing the stainless steel wear-resistant sleeve in the connecting hole. The matching groove provides a matching space for the mounting plate during the assembly of the conveyor chain. By utilizing the stainless steel wear-resistant sleeve, the chain's high-temperature resistance is increased, thermal creep is reduced, and its service life is extended.

[0017] 2. This utility model, by installing a lubrication mechanism, facilitates the lubrication of the sprocket, reducing chain wear. Prolonged contact between the conveyor chain and the sprocket leads to increased dry friction and thus increased chain wear. Therefore, this needs improvement. First, the sealing threaded cap in the oil reservoir is rotated out of the sealing ring, and lubricating oil is poured into the oil reservoir. Then, the sealing threaded cap is installed inside the oil reservoir. Subsequently, when lubrication of the sprocket is not required, the sealing threaded cap in the oil outlet does not need to be removed. If lubrication is required, the sealing threaded cap in the oil outlet is removed, causing the sprocket to press against the contact block. This causes the contact rod to move, the slider to move on the limit rod, and the spring to be compressed, thus preventing the sealing block from sealing the oil outlet. Lubricating fluid drips onto the sprocket through the oil outlet, reducing conveyor chain wear and increasing its service life. Attached Figure Description

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A high-efficiency and durable municipal solid waste incineration conveyor chain includes: an outer chain plate 1, a middle chain plate 3, and a pin 4. The inner wall of the middle chain plate 3 is provided with a performance mechanism to increase the chain's high-temperature resistance, reduce thermal creep, and improve service life. The performance mechanism includes a stainless steel wear-resistant sleeve 7, a mounting plate 8, and an assembly screw groove 12. The stainless steel wear-resistant sleeve 7 is located on the inner wall of the connecting hole 6, and the mounting plate 8 is located on the outer wall of the stainless steel wear-resistant sleeve 7. The outer wall of the middle chain plate 3 is provided with a splicing screw groove 9, and a splicing screw 10 is installed on the outer wall of the mounting plate 8, with one end of the splicing screw 10 extending into the interior of the splicing screw groove 9. The outer wall of the outer chain plate 1 is provided with a matching groove 11, with one end of the matching groove 11 extending into the interior of the pin hole 5. The outer wall of the stainless steel wear-resistant sleeve 7 is provided with an assembly screw groove 12, and the outer wall of the middle chain plate 3 is provided with an operating groove 13. A threaded plate 14 is installed on the inner wall of the operating groove 13, and an assembly screw groove 12 is installed on the inner wall of the threaded plate 14. The screw 15 is assembled, with one end of the screw 15 penetrating the interior of the threaded plate 14 and the other end of the screw 15 located inside the assembly screw groove 12. A chain plate 2 is installed on the top of the outer chain plate 1, and a middle chain plate 3 is located on the outer wall of the outer chain plate 1. A pin hole 5 is provided on the inner wall of the outer chain plate 1, and a pin shaft 4 is provided on the inner wall of the pin hole 5. A connecting hole 6 is provided on the inner wall of the middle chain plate 3. The existing conveyor chain casting has a rough surface, poor precision, and low material density, resulting in low overall chain strength, easy breakage, few meshing surfaces between the sprocket and the chain, easy skipping of teeth, insufficient chain pitch and length precision, and multiple chains used simultaneously with inconsistent length changes, which leads to increased downtime for equipment repair and affects equipment working time. Therefore, improvements are needed. First, the conveyor chain is changed from a casting to a plate chain, which is cut into a whole by laser cutting and then heat-treated as a whole. The improved structure density enhances overall strength. The sprocket meshes with the outer chain link 1, increasing the meshing surface compared to before. The chain undergoes precision machining, ensuring accurate pitch and chain length, significantly reducing equipment maintenance time and improving work efficiency. The chain pin 4 is now welded instead of riveted, resolving the previous problem of disengagement due to thermal expansion and contraction. A stainless steel wear-resistant sleeve 7 is embedded in the middle chain link 3, increasing the chain's high-temperature resistance, reducing thermal creep, and extending its service life. First, the stainless steel wear-resistant sleeve 7 is moved to the connecting hole 6. Then, the assembly screw 15 is rotated to move in the threaded plate 14, moving one end of the assembly screw 15 into the assembly screw groove 12, thus fixing one end of the stainless steel wear-resistant sleeve 7. Then, the other end is fixed into the splicing screw groove 9 by the splicing screw 10, thus stably fixing the stainless steel wear-resistant sleeve 7 in the connecting hole 6. The matching groove 11 is used to provide a matching space for the mounting plate 8 when assembling the conveyor chain. By using the stainless steel wear-resistant sleeve 7, the high temperature resistance of the chain is increased, thermal creep is reduced, and service life is improved.

[0031] Please see Figure 3 , Figure 7 and Figure 8The outer wall of the chain plate 2 is provided with a lubrication mechanism to facilitate lubrication of the sprocket and reduce chain wear. The lubrication mechanism includes an oil reservoir 16, an oil outlet 25, and a contact rod 21. The oil reservoir 16 is located at the top of the chain plate 2. Sealing rings 17 are installed on the inner walls of both the oil reservoir 16 and the oil outlet 25. A sealing threaded cap 18 is provided on the inner wall of the sealing rings 17. A limit rod 19 is installed on the inner wall of the oil reservoir 16. A slider 20 is mounted around the outer wall of the limit rod 19. A contact rod 21 is installed on the outer wall of the slider 20. A contact block 26 is installed on the outer wall of the contact rod 21, and the contact block 26 is located below the chain plate 2. A sealing block 22 is installed on the outer wall of the contact rod 21. A plate 23 is installed on the inner wall of the oil reservoir 16. A spring 24 is installed on the outer wall of the plate 23, with one end of the spring 24 extending to the outer wall of the contact rod 21. The sealing block 22 is located above the oil outlet 25. The bottom of the chain plate 2 is provided with... There is an oil outlet 25, one end of which extends into the oil storage tank 16. Prolonged contact between the conveyor chain and the sprocket leads to increased dry friction and thus increased chain wear. Therefore, improvements are needed. First, the sealing threaded cap 18 in the oil storage tank 16 is rotated out of the sealing ring 17, and lubricating oil is poured into the oil storage tank 16. Then, the sealing threaded cap 18 is installed inside the oil storage tank 16. When lubrication of the sprocket is not required, the sealing threaded cap 18 in the oil outlet 25 does not need to be removed. If lubrication is required, the sealing threaded cap 18 in the oil outlet 25 is removed, causing the sprocket to press against the contact block 26. This causes the contact rod 21 to move, the slider 20 to move on the limit rod 19, and the spring 24 to be compressed. This causes the sealing block 22 to not seal the oil outlet 25, allowing lubricating fluid to drip onto the sprocket through the oil outlet 25, thus reducing chain wear and increasing the chain's service life.

[0032] The existing conveyor chain, made of cast iron, has a rough surface, poor precision, and low material density, resulting in low overall strength and easy breakage. It also has limited meshing surface between the sprocket and chain, leading to tooth skipping. Furthermore, the chain pitch and length accuracy are insufficient. When multiple chains are used simultaneously, inconsistent length variations among the individual chains prevent synchronized operation, increasing downtime for repairs and impacting equipment operating time. Therefore, improvements are needed. Firstly, the conveyor chain will be changed from a cast iron to a plate chain, using laser cutting for integral blanking and overall heat treatment. The improved structure density enhances overall strength. The sprocket meshes with the outer chain piece 1, increasing the meshing surface compared to before. The chain undergoes precision machining, ensuring accurate pitch and chain length, significantly reducing equipment maintenance time and improving work efficiency. The chain pin 4 is welded instead of riveted, resolving the previous problem of disengagement due to thermal expansion and contraction. A stainless steel wear-resistant sleeve 7 is embedded in the middle chain piece 3, increasing the chain's high-temperature resistance, reducing thermal creep, and extending its service life. First, the stainless steel wear-resistant sleeve 7 is moved into the connecting hole 6. Then, the assembly screw 15 is rotated to move within the threaded plate 14, moving one end of the assembly screw 15 into the assembly screw groove 12, thus fixing one end of the stainless steel wear-resistant sleeve 7. The other end is then fixed to the splicing screw groove 9 via the splicing screw 10, stably securing the stainless steel wear-resistant sleeve 7 in the connecting hole 6. The matching groove 11 provides a fitting space for the mounting plate 8 during conveyor chain assembly. In the meantime, stainless steel wear-resistant sleeves 7 are used to increase the chain's high-temperature resistance, reduce thermal creep, and improve service life. Prolonged contact between the conveyor chain and sprocket leads to increased dry friction and increased chain wear. Therefore, improvements are needed. First, the sealing threaded top cover 18 in the oil storage tank 16 is rotated out of the sealing screw ring 17, and lubricating oil is poured into the oil storage tank 16. Then, the sealing threaded top cover 18 is installed inside the oil storage tank 16. Subsequently, when lubrication of the sprocket is not required, the sealing threaded top cover 18 in the oil outlet 25 does not need to be removed. If lubrication is required, the sealing threaded top cover 18 in the oil outlet 25 is removed, causing the sprocket to press against the contact block 26. This causes the contact rod 21 to move, the slider 20 to move on the limit rod 19, and the spring 24 to be compressed. This causes the sealing block 22 to not seal the oil outlet 25, allowing lubricating fluid to drip onto the sprocket through the oil outlet 25, thus reducing chain wear and improving the chain's service life.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
