Abstract

This utility model discloses a cleaning device for processing mechanical seals, relating to the field of mechanical seal processing technology. The key technical points are: a cleaning device for processing mechanical seals includes a frame, with a cleaning tank installed on the inner wall of the frame; the device drives a roller assembly to slowly swing left and right along its axis via a drive assembly, reducing the movement speed of the mechanical seals and thus reducing damage caused by collisions between the mechanical seals or with the inner wall of the roller assembly. Simultaneously, the drive assembly can also drive a buffer assembly to reciprocate along the axis of the roller assembly via a transmission assembly, with the buffer assembly swinging in the opposite direction to the roller assembly. This allows the buffer assembly to catch the mechanical seals, further reducing damage during cleaning. After colliding with the buffer assembly, the mechanical seals can fall into the rollers for flipping and cleaning, resulting in a more thorough cleaning.

Description

Technical Field

[0001] This utility model relates to the field of mechanical seal processing technology, and more specifically, it relates to a cleaning device for mechanical seal processing. Background Technology

[0002] Mechanical seals are sealing devices used in rotating machinery to prevent the working medium (such as liquids, gases, etc.) from leaking from the inside of the equipment to the outside, and also to prevent external impurities from entering the equipment. They are mainly composed of components such as rotating rings, stationary rings, springs, and sealing rings. The rotating rings or stationary rings need to be cleaned with a cleaning device after processing.

[0003] Cleaning devices for mechanical seal processing are categorized into rotary brush cleaning devices, high-pressure water jet cleaning devices, ultrasonic cleaning devices, spray cleaning devices, and drum cleaning devices. Drum cleaning devices typically include: 1. A drum: the core component, usually made of stainless steel or similar materials, with holes of varying sizes punched into its surface; 2. A transmission mechanism: including a motor, reducer, gears, and drive shaft, providing power for drum rotation and ensuring it operates at a suitable speed; 3. A spray system: consisting of a water pump, water pipes, and nozzles, pressurizing water and spraying it evenly onto the material inside the drum for rinsing; 4. Support components: such as rollers and brackets, used to support the drum and ensure its stability during rotation; 5. A control system: capable of controlling parameters such as cleaning time, drum speed, and spray water volume, some also featuring automated operation and monitoring functions.

[0004] In existing cleaning devices for mechanical seal processing, the seal may collide and rub against the inner wall of the drum or other components during the rotation of the drum. For some mechanical seals with high surface precision requirements, this can easily cause damage and affect their sealing performance. Therefore, in order to solve the above technical problems, this application proposes a cleaning device for mechanical seal processing. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cleaning device for mechanical seal processing, so as to solve the technical problem that the existing cleaning devices for mechanical seal processing are prone to damage when cleaning mechanical seals.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for processing mechanical seal components, comprising:

[0007] A frame, the inner wall of which is equipped with a cleaning tank;

[0008] The roller assembly is rotatably mounted on the inner wall of the cleaning tank;

[0009] The drive assembly includes a driven disc fixed to the bottom of the outer end face of the roller assembly. A vertical groove is provided on the driven disc, and a drive column is slidably connected in the vertical groove. A drive disc is fixed to the outer end face of the drive column and located at the edge of the drive disc. A first spur gear is fixed to the shaft center of the drive disc through a connecting rod, and a first pulley is fixed to the shaft center of the first spur gear.

[0010] The transmission assembly, connected to the power output end of the drive assembly, includes a third sprocket, with a first sector gear and a second sector gear respectively provided at both ends of the third sprocket for meshing with it, the first sector gear and the second sector gear rotating in opposite directions.

[0011] A buffer assembly, disposed inside the roller assembly, includes a shaft, which is rotatably connected to the axis of the roller assembly and has a third spur gear fixed at its end.

[0012] Preferably, the roller assembly includes a roller body, a filter cover is hinged to the top opening of the roller body, and a snap-fit ​​assembly is installed on the corresponding part of the outer side wall of the filter cover.

[0013] Preferably, end rings are fixed at the center of each end of the roller body, and the end rings rotate on the inner wall of the cleaning tank.

[0014] Preferably, a second sprocket is meshed with the outer wall of the first sprocket, and an electric motor is connected to the power input end of the second sprocket. The diameter of the first sprocket is larger than that of the second sprocket.

[0015] Preferably, a buffer sheet is fixed to the outer wall of the shaft, and a flexible sleeve is installed on the outer wall of the buffer sheet.

[0016] Preferably, a fourth sprocket is coaxially fixed to the outer wall of the second sector gear and the fourth sprocket is meshed with the outer wall of the first sprocket. A second pulley is coaxially disposed on the outer wall of the first sector gear, and the outer wall of the second pulley is connected to the first pulley through the belt body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model relates to a cleaning device for mechanical seal processing. A drive assembly drives a roller assembly to slowly oscillate left and right along its axis, reducing the movement speed of the mechanical seal and thus minimizing damage caused by collisions between the mechanical seal and the inner wall of the roller assembly. Simultaneously, the drive assembly, through a transmission assembly, drives a buffer assembly to reciprocate along the axis of the roller assembly. The buffer assembly's oscillation direction is always opposite to that of the roller assembly, catching the mechanical seal and further reducing damage during cleaning. After colliding with the buffer assembly, the mechanical seal can fall back into the roller for a more thorough cleaning, resulting in a cleaner finish. This solves the problem of damage to mechanical seals caused by existing cleaning devices for mechanical seal processing. Attached Figure Description

[0029] like Figure 1-4 As shown, this utility model provides a cleaning device for processing mechanical seals, comprising:

[0030] Frame 1, with a cleaning tank 2 installed on the inner side wall of frame 1;

[0031] The roller assembly 3 is rotatably installed on the inner wall of the cleaning tank 2. The roller assembly 3 includes a roller body 301. A filter cover plate 302 is hinged to the top opening of the roller body 301. A buckle assembly 303 is installed on the corresponding position of the outer side wall of the filter cover plate 302. End rings 304 are fixed at the shaft centers at both ends of the roller body 301. The end rings 304 rotate on the inner wall of the cleaning tank 2. The top opening of the roller body 301 facilitates the feeding and unloading of materials. The roller body 301 rotates on the inner wall of the cleaning tank 2 through the end rings 304 at the shaft centers at both ends, which facilitates the swinging action along the shaft center of the roller body 301, causing the internal mechanical seal to move and change direction slowly, which facilitates the cleaning work.

[0032] Furthermore, the drive assembly 4 includes a driven disk 401 fixed to the bottom of the outer end face of the roller assembly 3. A vertical groove 402 is provided on the driven disk 401. An active column 404 is slidably connected in the vertical groove 402. An active disk 403 is fixed to the outer end face of the active column 404 and is located at the edge of the active disk 403. A first spur gear 406 is fixed to the axis of the active disk 403 through a connecting rod 405. A first pulley 409 is fixed to the axis of the first spur gear 406. When the active disk 403 rotates, it can drive the active column 404 to make a circular motion along the axis of the active disk 403. Since the active column 404 is slidably connected in the vertical groove 402 of the driven disk 401, it can drive the driven disk 401 and the bottom of the roller assembly 3 to swing left and right, that is, the roller assembly 3 swings left and right along its own axis.

[0033] Furthermore, the transmission assembly 5, connected to the power output end of the drive assembly 4, includes a third sprocket 503. The third sprocket 503 has a first sector gear 502 and a second sector gear 505 respectively at its two ends, capable of meshing with it. The first sector gear 502 and the second sector gear 505 rotate in opposite directions. A second sprocket 407 is meshed with the outer wall of the first sprocket 406. A motor 408 is connected to the power input end of the second sprocket 407. The diameter of the first sprocket 406 is larger than that of the second sprocket 407. A fourth sprocket 504 is coaxially fixed to the outer wall of the second sector gear 505 and meshes with the outer wall of the first sprocket 406. A second pulley 501 is coaxially arranged on the outer wall of the first sector gear 502. The outer wall of the pulley 501 is connected to the first pulley 409 via the belt body 506. When the first sprocket 406 rotates clockwise, it can drive the fourth sprocket 504 to rotate counterclockwise synchronously. At the same time, through the transmission of the first pulley 409, the belt body 506 and the second pulley 501, it drives the first sector gear 502 to rotate clockwise. When the first sector gear 502 rotates to mesh with the third sprocket 503, it drives the third sprocket 503 to rotate counterclockwise, that is, the buffer assembly 6 swings counterclockwise. When the second sector gear 505 rotates to mesh with the third sprocket 503, it drives the third sprocket 503 to rotate clockwise, that is, the buffer assembly 6 swings clockwise. The swing direction of the buffer assembly 6 is always opposite to the swing direction of the roller assembly 3.

[0034] Furthermore, the buffer assembly 6 is located inside the drum assembly 3 and includes a shaft 601. A buffer plate 602 is fixed to the outer wall of the shaft 601, and a flexible sleeve 603 is installed on the outer wall of the buffer plate 602. The shaft 601 is rotatably connected to the shaft center of the drum assembly 3 and a third spur gear 503 is fixed at its end. This can catch the mechanical seal and further reduce the damage caused during the cleaning process. After the mechanical seal collides with the buffer assembly 6, it can fall into the drum for flipping and cleaning, resulting in a more thorough cleaning.

[0035] Working principle: First, put the mechanical seal to be cleaned into the drum body 301, then close the filter cover 302 and lock it through the buckle assembly 303. The external power supply turns on the motor 408 through the external switch. The motor 408 drives the second sprocket 407 to rotate clockwise. The second sprocket 407 is externally meshed with the first sprocket 406 with a larger diameter, thereby driving the first sprocket 406 to rotate slowly counterclockwise.

[0036] The drive disc 403, which is coaxially fixed with the first spur gear 406 via the connecting rod 405, rotates counterclockwise in sync. This can drive the drive column 404 to make a circular motion along the axis of the drive disc 403. Since the drive column 404 is slidably connected in the vertical groove 402 of the driven disc 401, it can drive the driven disc 401 and the bottom of the roller assembly 3 to swing left and right, that is, the roller assembly 3 swings left and right along its own axis, thereby reducing the movement speed of the mechanical seal and reducing the damage to the mechanical seal caused by mutual collision or collision with the inner wall of the roller assembly 3.

[0037] Meanwhile, the drive component 4 can also drive the buffer component 6 to swing back and forth along the axis of the drum component 3 through the transmission component 5. The swing direction of the buffer component 6 is always opposite to the swing direction of the drum component 3. It can catch the mechanical seal and further reduce the damage caused during the cleaning process. After the mechanical seal collides with the buffer component 6, it can fall into the drum for flipping and cleaning, and the cleaning is relatively clean.

[0038] When the first sprocket 406 rotates counterclockwise, it can drive the fourth sprocket 504 to rotate clockwise synchronously. At the same time, through the first pulley 409, the belt body 506 and the second pulley 501, it drives the first sector gear 502 to rotate counterclockwise. When the first sector gear 502 rotates to mesh with the third sprocket 503, it drives the third sprocket 503 to rotate clockwise, that is, the buffer assembly 6 swings clockwise.

[0039] When the second sector gear 505 rotates to mesh with the third spur gear 503, it drives the third spur gear 503 to rotate counterclockwise, that is, the buffer assembly 6 swings counterclockwise. When the drive column 404 rotates to one end close to the second sector gear 505, it drives the roller assembly 3 to swing towards one end close to the second sector gear 505.

[0040] In actual use, the positions of the first sector gear 502 and the second sector gear 505 can be set so that when the roller assembly 3 swings towards the end closer to the second sector gear 505, the first sector gear 502 meshes with the third spur gear 503, driving the third spur gear 503 and the buffer assembly 6 to rotate clockwise. The swing direction of the buffer assembly 6 is always opposite to the swing direction of the roller assembly 3 (the motor 408 is an existing product on the market and is connected to an external power supply and an external switch).
