Description

Technical Field

[0001] This utility model relates to the field of casing crystallizer maintenance technology, and more specifically, to casing crystallizer maintenance tooling. Background Technology

[0002] A tubular crystallizer is a device used to crystallize solid particles from a solution. It is commonly used in chemical, pharmaceutical, and food processing industries. During the crystallization process, the inside of the tubular crystallizer is often subjected to high temperature, high pressure, and corrosion. Therefore, regular inspection and maintenance are required to ensure its normal operation and production efficiency. Because tubular crystallizers are usually composed of complex components and structures, specific maintenance tools are required for maintenance work. Appropriate tools can improve the efficiency and safety of maintenance operations and ensure that the maintenance process proceeds smoothly.

[0003] To facilitate comprehensive maintenance of the casing crystallizer from multiple angles, hoisting tools are used to lift the crystallizer and place it on the maintenance platform. The platform then secures the crystallizer, allowing it to rotate for easy maintenance. However, due to the large size and weight of the casing crystallizer, it is difficult to place it precisely on the maintenance platform, which affects the stability of the crystallizer during maintenance. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a tooling for the maintenance of a casing crystallizer. This tooling solves the technical problem that the casing crystallizer is difficult to place accurately on the maintenance table due to its large size and weight, which affects the stability of the casing crystallizer during maintenance.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a maintenance fixture for a casing crystallizer, including a frame, a hydraulic telescopic rod fixedly connected to the bottom inner wall of the frame, a push plate fixedly connected to the top of the hydraulic telescopic rod, and a plurality of symmetrically arranged connecting rods fixedly connected to the top of the push plate. The connecting rods are arranged in a stepped structure with sequentially shortening and uniform arrangement. Adjusting rollers are rotatably connected between the connecting rods. The outer wall of each adjusting roller is provided with uniformly arranged spiral protrusions. A symmetrically arranged arc-shaped bearing plate is fixedly connected to the inner wall of the frame. A motor is fixedly connected to the outer wall of the frame. The main shaft of the motor passes through the frame and is fixedly connected to a rubber transmission roller. The interior of the frame is equipped with... There is a lateral adjustment mechanism for adjusting the lateral position of the casing crystallizer. A hydraulic telescopic rod drives the push plate upwards, and the lateral adjustment mechanism automatically adjusts the lateral position of the casing crystallizer. Because the adjusting roller is connected to the connecting rod, and the connecting rod is a stepped structure that shortens sequentially and is evenly arranged, as the push plate moves upwards, the push plate drives the adjusting roller upwards via the connecting rod, gradually pushing the casing crystallizer towards the support plate. This ensures the casing crystallizer lands precisely on the support plate, increasing its stability when rotating. A motor drives the transmission roller, which in turn rotates the casing crystallizer through friction, facilitating maintenance by personnel.

[0006] Preferably, the lateral adjustment mechanism includes multiple fixed plates fixedly connected to the inner wall of the frame. Each fixed plate has a storage slot at its top, and multiple adjusting wheels are rotatably connected within each storage slot. The outer wall of the frame is provided with symmetrically arranged limiting rods. One end of each limiting rod passes through the frame and is fixedly connected to an adjusting plate. A spring is fixedly connected to the end of each adjusting plate that is fixedly connected to the limiting rod. The spring sleeves the limiting rod and is fixedly connected to the inner wall of the frame. The top of the push plate is fixedly connected with multiple symmetrically arranged abutments, with the abutments inclined at the end closest to the adjusting plate. As the push plate moves upward, it drives the abutments to move, causing the abutments to push the adjusting plate, which in turn pulls the spring and moves the adjusting plate. This causes the adjusting plate to push the casing crystallizer laterally on the adjusting wheels, thus ensuring the casing crystallizer is precisely positioned between the fixed plates.

[0007] Preferably, a conveyor belt is fitted between the adjusting wheels; the conveyor belt can prevent the casing crystallizer and the adjusting wheels from getting stuck when they come into direct contact.

[0008] Preferably, each of the bearing plates is fixedly connected to a baffle; by setting the baffle, the casing crystallizer is prevented from shifting when rotating on the bearing plate, thereby increasing the stability of the casing crystallizer when rotating.

[0009] Preferably, the top of the support plate is embedded with a plurality of freely rotatable support rods; by setting the support rods, the casing crystallizer rotates on the support rods, preventing wear between the casing crystallizer and the support plate during rotation.

[0010] Preferably, the end of the adjusting plate near the limiting rod is inclined to correspond to the inclined part of the abutment plate; thereby preventing the abutment plate from wearing and getting stuck when pushing the adjusting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting up a hydraulic telescopic rod, a push plate, a connecting rod, an adjusting roller, a spiral protrusion, and a bearing plate, allows the hydraulic telescopic rod to drive the push plate to move upward. The lateral adjustment mechanism automatically adjusts the lateral position of the casing crystallizer. Because the adjusting roller is rotatably connected to the connecting rod, and the connecting rod is a stepped structure that shortens sequentially and is evenly arranged, as the push plate moves upward, the push plate drives the adjusting roller to move upward through the connecting rod, gradually pushing the casing crystallizer so that it gradually moves onto the bearing plate. This ensures that the casing crystallizer lands accurately on the bearing plate, increasing the stability of the casing crystallizer when it rotates on the bearing plate. Furthermore, the motor drives the transmission roller, which in turn drives the casing crystallizer to rotate through friction, thus facilitating maintenance of the casing crystallizer by the staff.

[0013] 2. The spiral protrusions on the adjusting roller in this utility model provide a certain gripping force when the adjusting roller pushes up the casing crystallizer and moves it toward the carrier plate, making the casing crystallizer more stably conveyed. At the same time, it can reduce the possibility of accidental slippage or deviation, and can increase the functionality and applicability of the adjusting roller.

[0014] 3. In this utility model, when placing the casing crystallizer on the fixed plate, there is no need to intervene in the placement process or adjust the position of the casing crystallizer during placement, which can increase the convenience and efficiency of the casing crystallizer maintenance.

[0021] like Figures 1 to 4 As shown, this utility model relates to a maintenance fixture for a casing crystallizer, comprising a frame 1. A hydraulic telescopic rod 2 is fixedly connected to the bottom inner wall of the frame 1. A push plate 3 is fixedly connected to the top of the hydraulic telescopic rod 2. A plurality of symmetrically arranged connecting rods 4 are fixedly connected to the top of the push plate 3. The connecting rods 4 are arranged in a stepped structure with sequentially shortening and uniform arrangement. Adjusting rollers 5 are rotatably connected between the connecting rods 4. The outer wall of each adjusting roller 5 is provided with uniformly arranged spiral protrusions 6. A symmetrically arranged arc-shaped bearing plate 7 is fixedly connected to the inner wall of the frame 1. A motor 8 is fixedly connected to the outer wall of the frame 1. The main shaft of the motor 8 passes through the frame 1 and is fixedly connected to a rubber transmission roller 9. The interior of the frame 1 is provided with a mechanism for adjusting the lateral position of the casing crystallizer. The lateral adjustment mechanism automatically adjusts the lateral position of the casing crystallizer by moving the push plate 3 upward through the hydraulic telescopic rod 2. Since the adjusting roller 5 is rotatably connected to the connecting rod 4, which is a stepped structure with sequentially shortened and evenly arranged sections, as the push plate 3 moves upward, it drives the adjusting roller 5 upward through the connecting rod 4, gradually pushing the casing crystallizer towards the support plate 7. This ensures the casing crystallizer lands precisely on the support plate 7, increasing its stability during rotation. The motor 8 drives the transmission roller 9, which in turn rotates the casing crystallizer through friction, facilitating maintenance by the staff.

[0022] Furthermore, the lateral adjustment mechanism includes multiple fixed plates 10 fixedly connected to the inner wall of the frame 1. Each fixed plate 10 has a storage groove 11 on its top, and multiple adjusting wheels 12 are rotatably connected in each storage groove 11. The outer wall of the frame 1 is provided with symmetrically arranged limiting rods 13. One end of the limiting rod 13 passes through the frame 1 and is fixedly connected to an adjusting plate 14. The end of the adjusting plate 14 fixedly connected to the limiting rod 13 is fixedly connected to a spring 15. The spring 15 sleeves the limiting rod 13 and is fixedly connected to the inner wall of the frame 1. The top of the push plate 3 is fixedly connected with multiple symmetrically arranged abutment plates 16. The end of the abutment plate 16 near the adjusting plate 14 is inclined. As the push plate 3 moves upward, it drives the abutment plate 16 to move, so that the abutment plate 16 pushes the adjusting plate 14, causing the adjusting plate 14 to pull the spring 15 and start to move. This causes the adjusting plate 14 to push the casing crystallizer to move laterally on the adjusting wheels 12, so that the casing crystallizer is accurately positioned between the fixed plates 10.

[0023] Furthermore, a conveyor belt 17 is fitted between the adjusting wheels 12; the conveyor belt 17 can prevent the casing crystallizer and the adjusting wheels 12 from getting stuck when they come into direct contact.

[0024] Furthermore, baffles 18 are fixedly connected to the top of each of the bearing plates 7; by setting baffles 18, the casing crystallizer is prevented from shifting when rotating on the bearing plate 7, thereby increasing the stability of the casing crystallizer when rotating.

[0025] Furthermore, multiple freely rotatable support rods 19 are embedded in the top of the support plate 7; by setting the support rods 19, the casing crystallizer rotates on the support rods 19, preventing wear between the casing crystallizer and the support plate 7 when rotating.

[0026] Furthermore, the end of the adjusting plate 14 near the limiting rod 13 is inclined to correspond to the inclined part of the abutment plate 16; thereby preventing the abutment plate 16 from wearing and getting stuck when pushing the adjusting plate 14.

[0027] Working Principle: This embodiment provides a casing crystallizer maintenance fixture. In use, the casing crystallizer requiring maintenance is placed on the adjusting wheel 12 using a hoisting tool. The fixing plate 10 is supported by the adjusting wheel 12. The extension of the hydraulic telescopic rod 2 can drive the push plate 3 upward. The upward movement of the push plate 3 will simultaneously drive the abutment plate 16 and connecting rod 4 upward. The upward movement of the abutment plate 16, with its inclined section, will push the adjusting plate 14, causing the adjusting plate 14 to pull the spring 15 and begin to move together with the limiting rod 13. The movement of the adjusting plate 14 then moves the casing crystallizer... The pushing action causes the casing crystallizer to move laterally on the adjusting wheel 12, positioning it in the middle of the bearing plate 7. The upward movement of the connecting rod 4 causes the adjusting roller 5 to move upward as well. The connecting rod 4 is a stepped structure that is shortened sequentially and evenly arranged. Therefore, as the push plate 3 moves upward, it pushes the casing crystallizer gradually through the connecting rod 4 and the adjusting roller 5, causing the casing crystallizer to move gradually onto the bearing plate 7. This ensures that the casing crystallizer lands precisely on the bearing plate 7, increasing the stability of the casing crystallizer when it rotates on the bearing plate 7.

[0028] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
