Description

Technical Field

[0001] The invention relates to the technical field of adipic acid production, in particular to a conveying device for adipic acid production. Background Art

[0002] In the prior art, the adipic acid conveying device is a key part in the production of adipic acid. At present, the pipe chain conveyor is commonly used. The pipe chain conveyor is a continuous conveying equipment for conveying bulk materials such as powder, small particles and small blocks. It can convey horizontally, inclined and vertically. It is generally used in fine chemicals, pesticides and minerals, building materials and food industries.

[0003] A straight and curved auxiliary guide device for a high-end manufacturing pipe chain conveyor disclosed in the Chinese patent announcement number CN112110131B drives the chain to circulate in a closed pipe through a driving device, and the chain pieces installed on the chain run synchronously. After the material enters the pipe from the feed port, it is pushed by the chain pieces to move along the inner wall of the pipe. Under the continuous push of the chain pieces, the material is gradually conveyed to the discharge port, thereby completing the material conveying process.

[0004] However, compared with the existing technologies in the related fields, firstly, since there is a gap between the chain pieces and the pipe wall of the existing pipe chain conveyor, and it is impossible to adjust in real time according to the position of the pipe wall, this gap is likely to cause material leakage during the material conveying process, especially in the arc section of the pipeline. Problems may occur in the fit between the chain pieces and the pipe wall of the existing pipe chain conveyor, resulting in uneven gaps. Therefore, the chain pieces cannot always maintain a good contact state with the pipe wall, which may cause jamming or material accumulation during the conveying process, thereby affecting the stable conveying of materials and limiting its effective application in complex pipeline layout scenarios; secondly, due to the inappropriate gap between the chain pieces and the pipe wall of the existing pipe chain conveyor, the chain pieces are often stuck in the pipe wall. The chain is prone to tilt, which will cause excessive collision and friction. This collision and friction will cause wear on the chain and the pipe wall, affecting the normal operation of the equipment. It will also cause the chain to twist. Once the chain breaks due to twisting, the entire conveying process will stop immediately, which will cause the material to stagnate in the pipeline. For continuous industrial processes, the upstream and downstream production links will be disconnected, and some chemical substances may be exposed during work, and the fallen debris may react chemically with the material. When conveying acidic or alkaline materials in the chemical industry, metal debris may react with the material to change the chemical composition of the material, thereby affecting the quality and performance of the material. Summary of the invention

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

[0007] Furthermore, the upper drive assembly has the same structure as the lower drive assembly. The lower drive assembly includes a lower shell, and the upper shell is fixedly installed on the top of the lower shell. The interiors of the lower shell and the upper shell are both provided with arc-shaped half-tubes connected to the first pipe and the second pipe. A sprocket meshing with the chain is rotatably provided inside the lower shell, and a driving element for controlling the rotation of the sprocket is fixedly installed on the top of the upper shell.

[0008] Furthermore, a feed port is provided on a side of the first pipeline close to the lower driving assembly, and a discharge port is provided on a side of the first pipeline close to the upper driving assembly.

[0009] Furthermore, a receiving groove is provided at a position on the outer surface of the chain sheet corresponding to the positions of the plurality of extrusion pieces, and the plurality of extrusion pieces are slidably arranged inside the receiving groove.

[0010] Furthermore, the shape of the plurality of extrusion pieces is fan-shaped, and a curved surface is formed on a side of the extrusion piece away from the accommodating groove.

[0011] Furthermore, the fan-shaped extrusion piece can improve the extension effect of the flexible sleeve, effectively improve the fit between the flexible sleeve and the pipe wall, and the curved surface on the extrusion piece can prevent damage to the flexible sleeve.

[0012] Furthermore, the contact assembly includes a connecting piece fixedly mounted on the extrusion piece, and the connecting piece is provided with a ball that contacts the inner walls of the first pipe and the second pipe.

[0013] Furthermore, the shape of several connecting members is L-shaped, and the chain plates are provided with sliding grooves at positions corresponding to the several connecting members, and the connecting members and the sliding grooves are connected by elastic members.

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

[0015] Furthermore, a rotation hole is provided at the bottom end of the lower shell body located at the sprocket, and the sprocket is connected to the rotation hole through a bearing.

[0016] The beneficial effects of the present invention are as follows: by arranging a flexible sleeve, an extrusion component and a contact component, and utilizing the contact component to fit with the pipe walls of the first pipe and the second pipe, the extrusion component can reduce the gap between the flexible sleeve and the pipe wall in real time according to the position of the pipe wall, so that the flexible sleeve can perfectly fit with the pipe when passing through the arc section, which can effectively avoid material leakage due to excessive gap, and prevent jamming or material accumulation due to poor fit between the chain piece and the pipe wall. At the same time, with the support of the ball, the chain piece can be prevented from tilting. Good fit can reduce excessive collision and friction between the chain piece and the pipe wall due to inappropriate gap, and the chain will not be excessively twisted, effectively ensuring the service life of the equipment.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Additional aspects and advantages of the present invention will be further given in the following description in conjunction with the accompanying drawings, and in part will become apparent from the following description, or may be learned through practice of the present invention.

[0031] An embodiment of a conveying device for producing adipic acid according to the present invention is as follows: Figures 1 to 10 As shown, it includes an upper driving component 1, a lower driving component 2, a chain 3, a first pipe 4 and a second pipe 5. A plurality of chain plates 6 are evenly spaced on the chain 3. The chain 3 and the chain plates 6 are inserted into the upper driving component 1, the lower driving component 2, the first pipe 4 and the second pipe 5. The upper driving component 1 and the lower driving component 2 are used to control the movement of the chain 3 in the first pipe 4 and the second pipe 5. A flexible sleeve 7 is fixedly provided on the outer surface of the chain plate 6. The chain plate 6 is located inside the flexible sleeve 7 and is slidably provided with a plurality of extrusions 8. Contact components 9 are provided on the plurality of extrusions 8. The contact components 9 are fitted with the pipe walls of the first pipe 4 and the second pipe 5, so that the extrusions 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 driving assembly 1 has the same structure as the lower driving assembly 2. The lower driving assembly 2 includes a lower shell 201, and an upper shell 202 is fixedly installed on the top of the lower shell 201. The interiors of the lower shell 201 and the upper shell 202 are both provided with arc-shaped half-tubes 203 connected with the first pipe 4 and the second pipe 5. A sprocket 204 meshing with the chain 3 is rotatably provided inside the lower shell 201, and a driving element 205 for controlling the rotation of the sprocket 204 is fixedly installed on the top of the upper shell 202. A rotating hole is opened at the bottom end of the lower shell 201 located at the sprocket 204, and the sprocket 204 is connected to the rotating hole through a bearing. The provided bearing can reduce the friction force when the sprocket 204 rotates, thereby improving the The stability of the high sprocket 204 during rotation; a feed port 401 is provided on the side of the first pipeline 4 close to the lower drive component 2, and a discharge port 402 is provided on the side of the first pipeline 4 close to the upper drive component 1. When in use, the sprocket 204 is controlled to rotate by the driving element 205, so that the sprocket 204 controls the chain 3 to move in the first pipeline 4 and the second pipeline 5, and then the adipic acid raw material can be introduced into the first pipeline 4 from the feed port 401, and the chain 3 moves in the first pipeline 4, so that a plurality of chain plates 6 and a plurality of flexible sleeves 7 can transport the adipic acid raw material from the feed port 401 of the first pipeline 4 to the discharge port 402 of the first pipeline 4, and then the adipic acid raw material is discharged through the discharge port 402.

[0033] like Figures 7 to 9 As shown, a receiving groove 601 is opened at the position corresponding to the plurality of extrusion pieces 8 on the outer surface of the chain piece 6, and the plurality of extrusion pieces 8 are slidably arranged inside the receiving groove 601; the plurality of extrusion pieces 8 are fan-shaped, and a curved surface is formed on the side of the extrusion piece 8 away from the receiving groove 601; the use of the fan-shaped extrusion piece 8 can improve the extension effect of the flexible sleeve 7, and effectively improve the fit between the flexible sleeve 7 and the pipe wall, and the curved surface on the extrusion piece 8 can prevent damage to the flexible sleeve 7.

[0034] like Figure 5 , Fig. 9 and Fig.10 As shown, the contact assembly 9 includes a connector 901 fixedly mounted on the extrusion member 8, and a ball 902 is provided on the connector 901 for contacting the inner walls of the first pipe 4 and the second pipe 5. Several connectors 901 are L-shaped, and the chain pieces 6 are provided with slide grooves 602 at positions corresponding to several connectors 901. The connectors 901 and the slide grooves 602 are connected by elastic members 603. When the chain pieces 6 are moving, some of the ball 902 can control the extrusion member 8 to push the flexible sleeve 7 through the connector 901, and some of the ball 902 can control the extrusion member 8 to pull the flexible sleeve 7 through the connector 901, so that the flexible sleeve 7 can perfectly fit with the pipe when passing through the arc section.

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

[0036] Significant anti-leakage effect: Traditional pipe chain conveyors may cause leakage due to the gap between the chain piece 6 and the pipe wall. In this new design, the contact component 9 and the extrusion piece 8 can adjust the gap between the flexible sleeve 7 and the pipe wall in real time according to the position of the pipe wall, effectively avoiding a large amount of leakage caused by excessive gap (when conveying various materials, whether powdery, granular or small block materials, they can be better constrained in the pipe, reducing material loss and improving the sealing of the conveying process).

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

[0038] Improved conveying efficiency: Since material leakage is reduced, materials can be conveyed more completely in the pipeline, avoiding the interruption of conveying caused by frequent cleaning and replenishment of materials due to material leakage. Moreover, the conveying can be stable in the curved section of the pipeline, and there will be no jamming or material accumulation due to poor adhesion between the chain piece 6 and the pipe wall.

[0039] Extend the service life of the equipment: Good fit can reduce excessive collision and friction between the chain piece 6 and the pipe wall due to inappropriate gap. At the same time, with the support of the ball 902, the chain piece 6 can be prevented from tilting. Good fit can reduce excessive collision and friction between the chain piece 6 and the pipe wall due to inappropriate gap, and the chain 3 will not twist excessively, effectively ensuring the service life of the equipment.

[0040] The working process is as follows:

[0041] S1: Figures 1 to 3 As shown, when in use, the sprocket 204 is controlled to rotate by the driving element 205, so that the sprocket 204 controls 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: Figures 1 to 4As shown, the chain 3 moves in the first pipe 4, so that the chain pieces 6 and the 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: Figure 1 , Figure 3 , Figure 7 , Figure 8 and Fig.10 As shown, when the chain piece 6 moves, the ball 902 will contact the pipe walls of the arc-shaped half pipe 203, the first pipe 4 and the second pipe 5, so that part of the ball 902 can control the extrusion piece 8 to push the flexible sleeve 7 through the connecting piece 901, and part of the ball 902 can control the extrusion piece 8 to pull the flexible sleeve 7 through the connecting piece 901, so that the flexible sleeve 7 can perfectly fit with the pipe when passing through the arc section (when the ball 902 is squeezed by the pipe wall, the connecting piece 901 squeezes the elastic piece 603 and slides inside the slide groove 602 toward the center of the chain piece 6, and when the ball 902 is not squeezed by the pipe wall, the elastic piece 603 prompts the connecting piece 901 to slide away from the center of the chain piece 6, so as to realize that the extrusion piece 8 pushes or pulls the flexible sleeve 7);

[0044] S4: In the curved section of the pipeline, the chain piece 6 of the ordinary pipe chain conveyor may have problems fitting with the pipe wall, resulting in uneven gaps. The step of S3 is like putting a "clothes" on the chain piece 6 of the pipe chain conveyor that can adapt to the shape of the pipe. For complex pipeline layouts, such as in conveying lines with multiple bends, this adaptive ability can ensure that the chain piece 6 can maintain good contact with the pipe wall during the entire conveying process, thereby stably conveying materials without being affected by changes in the pipe shape;

[0045] S5: With the support of the ball 902, the chain piece 6 can be prevented from tilting. Good fit can reduce excessive collision and friction between the chain piece 6 and the tube wall due to inappropriate clearance, 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 principle of the present invention should be included in the protection scope of the present invention.
