Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a cooler with a self-cleaning structure for a compressor. Background Art

[0002] The compressor cooler is also called the intercooler, which is mainly used for the intermediate cooling process of the compressor. It is usually located between two adjacent stages of the compressor to reduce the temperature and pressure of the compressed air so that the next stage of compression can be carried out more efficiently.

[0003] Compressor coolers mainly include water cooling, air cooling, and mixed cooling. At present, during the use of water-cooled coolers, the coolant contains certain impurities, which will affect the cooling efficiency. Therefore, the coolant needs to be replaced and the pipes need to be cleaned regularly. The cooler structure is relatively complex, which makes these maintenance tasks relatively complicated and costly. The patent document with the prior art publication number CN217582440U provides a cooler for a compressor. The device filters the cooling water through a filter to reduce the amount of debris entering the cooler body. At the same time, by separating the right end cover from the cooler body and pulling the two pull blocks to the opposite side to pull the plug block out of the slot, the ring can be removed and the filter can be maintained and replaced, thereby achieving the purpose of filtering the cooling water and facilitating the replacement and maintenance of the filter.

[0004] Although this device achieves cooling water filtration and convenient filter maintenance, the cooler needs to be suspended during filter replacement, which causes the compressor to malfunction during this period. Therefore, a cooler with a self-cleaning structure for the compressor is urgently needed to solve the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0006] Specifically, the technical problem to be solved by the present invention is to provide a cooler with a self-cleaning structure for a compressor, so as to solve the current technical problem that the working state of the cooler equipment needs to be suspended during the process of replacing the filter, which will cause the compressor to fail to work normally during this period of time.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A cooler with a self-cleaning structure for a compressor includes a cooler main body and an end cover connected to one end of the cooler main body. An isolation box is provided in the middle of the end cover, and two partitions are fixedly connected in the isolation box. The isolation box and the partitions cooperate to form a water flow area and an isolation area. Filter elements are provided in the water flow area and the isolation area, and a cover plate is connected to the end cover. A drive rod is installed on the cover plate. The end of the drive rod passes through the isolation box and extends to the outside, and the drive rod is used to drive the filter element to rotate.

[0009] As an improved technical solution, the filter element includes a frame with a semicircular structure, a filter screen is fixedly connected to the frame, and the diameter of the filter element is adapted to the inner diameter of the end cover.

[0010] As an improved technical solution, two arc plates are fixedly connected in the water flow area, and the arc plates are in sliding contact with the lower filter element. Two limit plates are fixedly connected in the isolation area, and the limit plates are in sliding contact with the upper filter element.

[0011] As an improved technical solution, the driving rod is a worm, a semicircular worm gear ring is fixedly connected to the frame, and the driving rod is meshed with the worm gear ring for transmission.

[0012] As an improved technical solution, a sealing ring 1 is fixedly connected to the upper port of the isolation box, and a sealing ring 2 is fixedly connected to the bottom of the cover plate, and the sealing ring 1 is in abutment with the sealing ring 2.

[0013] As an improved technical solution, the end of the driving rod is fixedly connected to a handle, the driving rod is rotatably connected to the sealing ring 2, and the sealing ring 2 is fixedly connected to two waterproof rings, and the waterproof rings are rotatably connected to the driving rod.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are:

[0015] 1. The utility model has two filter elements respectively arranged in the water flow area and the isolation area of ​​the isolation box. The filter element in the water flow area is used to intercept impurities in the coolant. When it needs to be disassembled and replaced, the driving rod can be rotated to swap the positions of the filter elements in the water flow area and the isolation area, and the filter element containing impurities can be taken out for cleaning without affecting the flow of the coolant, so that the cooler can work normally and has good practicality.

[0016] 2. After the utility model is connected to the isolation box through the cover plate, the drive rod is engaged with the worm gear ring. The one-way transmission property of the worm gear can be used to limit the rotation of the filter element. At the same time, pressure can be applied to the filter element to make it stably set in the isolation box, thereby improving the sealing performance of the filter element and the water flow area.

[0028] like Figure 1-4 As shown together, this embodiment provides a cooler with a self-cleaning structure for a compressor, and the cooler with a self-cleaning structure for the compressor includes a cooler body 1, and also includes an end cover 2 connected to one end of the cooler body 1. An isolation box 3 is provided in the middle of the end cover 2, and two partitions 301 are fixedly connected in the isolation box 3. The isolation box 3 and the partition 301 cooperate to form a water flow area 302 and an isolation area 303. Filter elements 4 are provided in the water flow area 302 and the isolation area 303, and a cover plate 5 is connected to the end cover 2. A drive rod 6 is installed on the cover plate 5. The end of the drive rod 6 passes through the isolation box 3 and extends to the outside, and the drive rod 6 is used to drive the filter element 4 to rotate.

[0029] In the above technical solution, when one of the filter elements 4 is arranged in the water-passing area 302, the coolant enters one end of the end cover 2 and impurities are intercepted by the filter element 4. When the driving rod 6 is rotated, the two filter elements 4 can be driven to rotate, so that the positions of the two filter elements 4 are exchanged. At this time, the new filter element 4 is arranged in the water-passing area 302, and the filter element 4 containing impurities is arranged in the isolation area 303, so that the cover plate 5 can be removed and the filter element 4 in the isolation area 303 can be taken out for cleaning.

[0030] Among them, a flange is fixed on one end of the end cover 2, and the end cover 2 is fixed to one end of the cooler body 1 through the flange and bolts.

[0031] The filter element 4 includes a frame 401 with a semicircular structure, and a filter screen 402 is fixedly connected to the frame 401. The diameter of the filter element 4 is adapted to the inner diameter of the end cover 2. The outer side of the frame 401 fits the inner cavity of the end cover 2, so that the filter element 4 is used to isolate the interior of the end cover 2, so that the passing coolant can intercept impurities through the filter screen 402.

[0032] Two arc-shaped plates 304 are fixedly connected in the water-passing area 302, and the arc-shaped plates 304 are in sliding contact with the lower filter element 4. Two limit plates 305 are fixedly connected in the isolation area 303, and the limit plates 305 are in sliding contact with the upper filter element 4. The arc-shaped plates 304 are in contact with the side of the frame 401 to ensure the sealing of the connection between the filter element 4 and the water-passing area 302 and prevent the coolant from leaking into the isolation area 303. The limit plates 305 are used to limit the upper filter element 4 so that the two filter elements 4 are arranged in a circular plate shape, thereby facilitating the driving rod 6 to drive the filter element 4 to rotate.

[0033] A rubber pad is fixedly provided on the side of the arc-shaped plate 304 facing the filter element 4 , and the rubber pad is in close contact with the frame 401 , thereby further improving the sealing effect.

[0034] The driving rod 6 is a worm, and a semicircular worm gear ring 403 is fixedly connected to the frame 401. The driving rod 6 is engaged with the worm gear ring 403 for transmission. When the cover plate 5 is connected to the isolation box 3, the driving rod 6 is engaged with one of the turbine rings 403. When the driving rod 6 rotates, it cooperates with the worm gear ring 403 to drive the filter element 4 to rotate, so that the two filter elements 4 can be swapped.

[0035] A sealing ring 1 306 is fixedly connected to the upper port of the isolation box 3, and a sealing ring 2 501 is fixedly connected to the bottom of the cover plate 5. The sealing ring 1 306 and the sealing ring 2 501 are in abutment with each other, and the abutment between the sealing ring 1 306 and the sealing ring 2 501 can improve the sealing performance of the connection between the cover plate 5 and the isolation box 3.

[0036] Among them, connecting ears are fixed at the corners of the cover plate 5 and the corners of the port of the isolation box 3. The cover plate 5 and the isolation box 3 are connected and fixed by the two connecting ears and bolts.

[0037] A handle 601 is fixedly connected to the end of the driving rod 6, and the driving rod 6 is rotatably connected to the sealing ring 2 501, and two waterproof rings 502 are fixedly connected to the sealing ring 2 501. The waterproof ring 502 is rotatably connected to the driving rod 6. The rotating handle 601 is used to drive the driving rod 6 to rotate, and the waterproof ring 502 is used to improve the sealing between the driving rod 6 and the sealing ring 2 501 to prevent water seepage.

[0038] During use, the lower filter element 4 cooperates with the water passage area 302 to filter and intercept impurities in the flowing coolant. When the filter element 4 in the water passage area 302 needs to be cleaned after being used for a period of time, the handle 601 is turned to drive the drive rod 6 to rotate, and the drive rod 6 cooperates with the turbine ring 403 to rotate the two filter elements 4, so that the positions of the two filter elements 4 are swapped. Then the cover plate 5 is opened, the filter element 4 in the isolation area 303 is taken out, and it is cleaned. After cleaning, it is installed in the isolation area 303, and then the cover plate 5 is connected to the isolation box 3 to achieve sealing.
