Description

Technical Field

[0001] This invention relates to the field of adipic acid production technology, and in particular to a conveying device for adipic acid production. Background Technology

[0002] In existing technologies, adipic acid conveying devices are a key part of adipic acid production. Currently, tubular chain conveyors are commonly used. Tubular chain conveyors are continuous conveying equipment for conveying bulk materials such as powders, small granules, and small lumps. They can be used for horizontal, inclined, and vertical combined conveying and are generally used in fine chemicals, pesticides and ores, building materials, and food industries.

[0003] A high-end manufacturing tubular chain conveyor straight-bend auxiliary guiding device is disclosed in Chinese Patent Publication No. CN112110131B. This device drives a chain to circulate within a closed pipe via a drive unit, with chain links mounted on the chain moving synchronously. After material enters the pipe through the inlet, it is propelled along the inner wall of the pipe by the chain links. Under the continuous pushing of the chain links, the material is gradually conveyed to the outlet, thus completing the material conveying process.

[0004] However, compared to existing technologies in related fields, firstly, due to the gap between the chain links and the pipe wall in existing tubular chain conveyors, and the inability to adjust the gap in real time according to the pipe wall position, this gap easily leads to material leakage during material conveying, especially in the curved sections of the pipeline. Problems with the fit between the chain links and the pipe wall in existing tubular chain conveyors can occur, resulting in uneven gaps. Therefore, the chain links cannot maintain a good contact with the pipe wall at all times, which may cause jamming or material accumulation during the conveying process, thus affecting the stable conveying of materials and limiting its effective application in complex pipeline layouts. Secondly, due to the unsuitable gap between the chain links and the pipe wall in existing tubular chain conveyors, the chain... The conveyor belt is prone to tilting, which can lead to excessive collisions and friction. This collision and friction can cause wear on the chain links and pipe walls, affecting the normal operation of the equipment. It can also cause the chain to twist. Once the chain breaks due to twisting, the entire conveying process will stop immediately. This will cause the material to stagnate in the pipeline. For continuous production industrial processes, this can cause the upstream and downstream production links to become disconnected. In addition, the conveyor belt may come into contact with some chemicals during operation. The debris that falls off may react with the material. In the chemical industry, when conveying acidic or alkaline materials, metal debris may react with the material, changing the chemical composition of the material and thus affecting the quality and performance of the material. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a conveying device for adipic acid production.

[0006] The objective of this invention is achieved through the following technical solution: A conveying device for adipic acid production includes an upper drive assembly, a lower drive assembly, a chain, a first pipe, and a second pipe. The chain has a plurality of chain segments spaced evenly apart. The chain and chain segments pass through the upper drive assembly, the lower drive assembly, the first pipe, and the second pipe. The upper drive assembly and the lower drive assembly control the movement of the chain in the first and second pipes. A flexible sleeve is fixedly provided on the outer surface of the chain segments. A plurality of extrusion members are slidably arranged inside the flexible sleeves of the chain segments. Each extrusion member is provided with a contact component. By utilizing the contact components to adhere to the pipe walls of the first and second pipes, the extrusion members can reduce the gap between the flexible sleeve and the pipe wall in real time according to the position of the pipe wall, thereby avoiding a large amount of material leakage due to excessive gap.

[0007] Furthermore, the upper drive assembly has the same structure as the lower drive assembly. The lower drive assembly includes a lower housing, and an upper housing is fixedly installed on the top of the lower housing. Both the lower housing and the upper housing have an arc-shaped half-tube connected to the first pipe and the second pipe inside. The lower housing has a sprocket that meshes with the chain inside. The top of the upper housing has a drive element for controlling the rotation of the sprocket fixedly installed.

[0008] Furthermore, the first pipe has an inlet on the side near the lower drive assembly and an outlet on the side near the upper drive assembly.

[0009] Furthermore, the outer surface of the chain link is provided with receiving grooves corresponding to the positions of several extrusion parts, and the several extrusion parts are slidably disposed inside the receiving grooves.

[0010] Furthermore, several extruded parts are fan-shaped, and the side of the extruded part away from the receiving groove is formed with an arc surface.

[0011] Furthermore, the use of a fan-shaped extruder can improve the elongation effect of the flexible sleeve, effectively improve the fit between the flexible sleeve and the pipe wall, and the arc surface on the extruder can prevent damage to the flexible sleeve.

[0012] Furthermore, the contact assembly includes a connector fixedly mounted on the extruder, the connector having balls that contact the inner walls of the first and second pipes.

[0013] Furthermore, several connectors are L-shaped, and the chain links are provided with grooves at the positions of several connectors. The connectors and the grooves are connected by elastic elements.

[0014] Furthermore, when the chain is moving, some of the balls can control the extrusion component to push the flexible sleeve through the connector, and some of the balls can control the extrusion component to pull the flexible sleeve through the connector, so that the flexible sleeve can perfectly fit the pipe when passing through the arc section.

[0015] Furthermore, the lower housing has a rotating hole at the bottom end of the sprocket, and the sprocket is connected to the rotating hole through a bearing.

[0016] The beneficial effects of this invention are as follows: By setting up a flexible sleeve, an extruder, and a contact assembly, and utilizing the contact assembly to fit against the walls of the first and second pipes, the extruder can reduce the gap between the flexible sleeve and the pipe wall in real time according to the position of the pipe wall. This allows the flexible sleeve to perfectly fit the pipe when passing through the arc section, effectively avoiding material leakage due to excessive gaps and preventing jamming or material accumulation due to poor fit between the chain and the pipe wall. At the same time, with the support of the ball bearings, it can prevent the chain from tilting. The good fit can reduce excessive collision and friction between the chain and the pipe wall due to unsuitable gaps, and the chain will not twist excessively, effectively ensuring the service life of the equipment.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Additional aspects and advantages of the invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0031] An embodiment of a conveying device for adipic acid production according to the present invention, such as... Figures 1 to 10 As shown, the assembly includes an upper drive component 1, a lower drive component 2, a chain 3, a first pipe 4, and a second pipe 5. The chain 3 has several chain pieces 6 evenly spaced on it. The chain 3 and chain pieces 6 pass through the upper drive component 1, the lower drive component 2, the first pipe 4, and the second pipe 5. The upper drive component 1 and the lower drive component 2 control the movement of the chain 3 within the first pipe 4 and the second pipe 5. A flexible sleeve 7 is fixedly provided on the outer surface of the chain piece 6. Several extrusion members 8 are slidably arranged inside the flexible sleeve 7 on the chain piece 6. Each extrusion member 8 is provided with a contact component 9. By using the contact component 9 to adhere to the pipe walls of the first pipe 4 and the second pipe 5, the extrusion member 8 can reduce the gap between the flexible sleeve 7 and the pipe wall in real time according to the position of the pipe wall, thereby avoiding a large amount of material leakage due to excessive gap.

[0032] like Figures 1 to 3As shown, the upper drive assembly 1 and the lower drive assembly 2 have the same structure. The lower drive assembly 2 includes a lower housing 201, and an upper housing 202 is fixedly installed on the top of the lower housing 201. Both the lower housing 201 and the upper housing 202 have arc-shaped half-section pipes 203 that communicate with the first pipe 4 and the second pipe 5 inside. A sprocket 204 that meshes with the chain 3 is rotatably installed inside the lower housing 201. A drive element 205 for controlling the rotation of the sprocket 204 is fixedly installed on the top of the upper housing 202. A rotation hole is opened at the bottom end of the sprocket 204 in the lower housing 201. The sprocket 204 is connected to the rotation hole through a bearing. By using the bearing, the friction force when the sprocket 204 rotates can be reduced, and the speed can be improved. Stability of the high-speed sprocket 204 during rotation; the first pipe 4 has an inlet 401 on the side near the lower drive assembly 2 and an outlet 402 on the side near the upper drive assembly 1. In use, the drive element 205 controls the sprocket 204 to rotate, thereby allowing the sprocket 204 to control the chain 3 to move in the first pipe 4 and the second pipe 5. Then, the adipic acid raw material can be introduced into the first pipe 4 from the inlet 401. By moving the chain 3 in the first pipe 4, several chain pieces 6 and several flexible sleeves 7 can transport the adipic acid raw material from the inlet 401 of the first pipe 4 to the outlet 402 of the first pipe 4, and then discharge the adipic acid raw material through the outlet 402.

[0033] like Figures 7 to 9 As shown, the outer surface of the chain link 6 is provided with receiving grooves 601 corresponding to the positions of several extrusion parts 8, and the several extrusion parts 8 are slidably disposed inside the receiving grooves 601; the shape of the several extrusion parts 8 is fan-shaped, and the side of the extrusion part 8 away from the receiving grooves 601 is formed with an arc surface; the fan-shaped extrusion parts 8 can improve the extension effect of the flexible sleeve 7, effectively improve the fit between the flexible sleeve 7 and the pipe wall, and the arc surface on the extrusion part 8 can prevent damage to the flexible sleeve 7.

[0034] like Figure 5 , Figure 9 and Figure 10 As shown, the contact assembly 9 includes a connector 901 fixedly mounted on the extruder 8. The connector 901 is provided with balls 902 that contact the inner walls of the first pipe 4 and the second pipe 5. The shape of several connectors 901 is L-shaped. The chain link 6 is provided with a groove 602 at the position of several connectors 901. The connectors 901 and the grooves 602 are connected by elastic members 603. When the chain link 6 moves, some balls 902 can control the extruder 8 to push the flexible sleeve 7 through the connector 901, and some balls 902 can control the extruder 8 to pull the flexible sleeve 7 through the connector 901, so that the flexible sleeve 7 can perfectly fit the pipe when passing through the arc section.

[0035] In summary, the advantages of this application are as follows:

[0036] Significantly effective at preventing material leakage: Traditional tubular chain conveyors may experience material leakage due to gaps between the chain links 6 and the pipe wall. However, in this new design, the contact components 9 and the extrusion components 8 can adjust the gap between the flexible sleeve 7 and the pipe wall in real time according to the pipe wall position, effectively avoiding large amounts of material leakage caused by excessive gaps (when conveying various materials, whether powdery, granular, or small lump materials, they can be better confined within the pipe, reducing material loss and improving the sealing of the conveying process).

[0037] Excellent adaptability: In the curved section of the pipeline, the chain link 6 of a conventional tubular chain conveyor may have problems fitting with the pipe wall, resulting in uneven gaps. However, in this design, the partial contact component 9 can control the extrusion component 8 to push the flexible sleeve 7, and partially control the extrusion component 8 to pull the flexible sleeve 7, so that the flexible sleeve 7 can perfectly fit with the pipeline when passing through the curved section (this is like putting a "clothes" on the chain link 6 of the tubular chain conveyor that can adapt to the shape of the pipeline. For complex pipeline layouts, such as in conveyor lines with multiple bends, this adaptability can ensure that the chain link 6 maintains a good contact state with the pipe wall throughout the conveying process, thereby stably conveying materials without being affected by changes in the shape of the pipeline).

[0038] Improved conveying efficiency: By reducing material leakage, materials can be conveyed more completely within the pipeline, avoiding conveying interruptions caused by frequent cleaning and replenishment due to material leakage. Furthermore, it can maintain stable conveying even in the curved sections of the pipeline, preventing jamming or material accumulation caused by poor contact between the chain link 6 and the pipe wall.

[0039] Extending equipment lifespan: Good fit can reduce excessive collision and friction between chain link 6 and tube wall due to improper gap. At the same time, with the support of ball bearing 902, it can prevent chain link 6 from tilting. Good fit can reduce excessive collision and friction between chain link 6 and tube wall due to improper gap. In addition, chain 3 will not be excessively twisted, effectively ensuring the service life of the equipment.

[0040] The work process is as follows:

[0041] S1: As Figures 1 to 3 As shown, during use, the drive element 205 controls the sprocket 204 to rotate, thereby allowing the sprocket 204 to control the chain 3 to move in the first pipe 4 and the second pipe 5, and then the adipic acid raw material can be introduced into the first pipe 4 from the feed port 401.

[0042] S2: As Figures 1 to 4As shown, the chain 3 moves in the first pipe 4, so that several chain pieces 6 and several flexible sleeves 7 can transport the adipic acid raw material from the feed port 401 of the first pipe 4 to the discharge port 402 of the first pipe 4, and then discharge the adipic acid raw material through the discharge port 402.

[0043] S3: As Figure 1 , Figure 3 , Figure 7 , Figure 8 and Figure 10 As shown, when the chain link 6 moves, the ball bearings 902 will contact the walls of the arc-shaped half-pipe 203, the first pipe 4, and the second pipe 5. Thus, some of the ball bearings 902 can control the extrusion member 8 to push the flexible sleeve 7 through the connector 901, and some of the ball bearings 902 can control the extrusion member 8 to pull the flexible sleeve 7 through the connector 901. This allows the flexible sleeve 7 to perfectly fit the pipe when passing through the arc section. (When the ball bearings 902 are squeezed by the pipe wall, the connector 901 will squeeze the elastic member 603 and slide towards the center of the chain link 6 inside the groove 602. When the ball bearings 902 are not squeezed by the pipe wall, the elastic member 603 will cause the connector 901 to slide away from the center of the chain link 6, so as to realize that the extrusion member 8 pushes or pulls the flexible sleeve 7.)

[0044] S4: In the curved sections of the pipeline, the chain links 6 of a conventional tubular chain conveyor may have problems adhering to the pipe wall, resulting in uneven gaps. Step S3 is like giving the chain links 6 of the tubular chain conveyor a "clothes" that can adapt to the shape of the pipeline. For complex pipeline layouts, such as in conveyor lines with multiple bends, this adaptive capability can ensure that the chain links 6 maintain good contact with the pipe wall throughout the conveying process, thereby stably conveying materials without being affected by changes in the shape of the pipeline;

[0045] S5: With the support of the ball bearing 902, it can prevent the chain link 6 from tilting. The good fit can reduce the excessive collision and friction between the chain link 6 and the tube wall due to improper gap, and the chain 3 will not be excessively twisted.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
