[0035] like Figure 7 and Fig. 9As shown, a positioning ring 20 is fixedly connected to the interior of the liquid storage tube 15, and the interior of the positioning ring 20 is filled with hydraulic oil. A moving ring 21 is slidably connected to the interior of the positioning ring 20. The moving ring 21 is squeezed and matched with the adjacent second moving block 18.

[0036] like Figure 3 , Fig.10 and Fig.11As shown, the two sealing covers 3 are both fixedly connected to the multi-stage telescopic rod 30, wherein the upper multi-stage telescopic rod 30 is located at the left front side of the adjacent sealing cover 3, and the lower multi-stage telescopic rod 30 is located at the right rear side of the adjacent sealing cover 3, and the fixed part of the multi-stage telescopic rod 30 is externally connected to an air pump, and the air pump delivers gas to the fixed part of the multi-stage telescopic rod 30, thereby moving the telescopic end of the multi-stage telescopic rod 30 downward, and an electromagnetic valve is arranged between the fixed part of the multi-stage telescopic rod 30 and the air pump, which is used to change the fixed part of the two multi-stage telescopic rods 30. The connection relationship between the multi-stage telescopic rod 30 and the air pump is that the telescopic part at the bottom side of the multi-stage telescopic rod 30 is slidably connected to the third push plate 31, and the lower side of the third push plate 31 is rotatably connected to the connecting rod 32. The third push plate 31 drives the connecting rod 32 to move downward synchronously. The connecting rod 32 is provided with a limiting groove slidably connected to the telescopic part adjacent to the adjacent multi-stage telescopic rod 30. The limiting groove on the connecting rod 32 is divided into a vertical groove and an arc groove, wherein the arc groove is located at the lower side of the adjacent vertical groove. In the process of the connecting rod 32 moving downward, the connecting rod 32 is connected to the air pump by the third push plate 31. The transmission between the arc groove on the lower side and the telescopic part of the adjacent multi-stage telescopic rod 30 causes the connecting rod 32 to rotate axially while moving downward, until the vertical groove on the connecting rod 32 contacts the telescopic part of the adjacent multi-stage telescopic rod 30, and the connecting rod 32 is limited by the telescopic part of the adjacent multi-stage telescopic rod 30 and no longer rotates. An elastic member 33 is fixedly connected between the third push plate 31 and the adjacent telescopic part of the adjacent multi-stage telescopic rod 30 and between the two adjacent telescopic parts of the multi-stage telescopic rod 30. The elastic member 33 is a tension spring. The elastic coefficients of the multiple elastic members 33 connected to a multi-stage telescopic rod 30 gradually increase from bottom to top, so that when the air pump delivers gas in the fixed part of the multi-stage telescopic rod 30, the telescopic part of the multi-stage telescopic rod 30 can move downward in sequence. The lower end of the connecting rod 32 is fixedly connected to a scraper 34. During the movement, the connecting rod 32 always drives the scraper 34 to move synchronously and adjusts the direction of the scraper 34. The scraper 34 contacts and cooperates with the adjacent filter cloth 5, and the scraper 34 removes impurities attached to the adjacent filter cloth 5.

[0037] like Figure 2 and Figure 4 As shown, two axially distributed electric push rods 50 are fixedly connected inside the support leg 1, and the two electric push rods 50 are electrically connected to the control terminal. The telescopic ends of the two electric push rods 50 are fixedly connected with guide blocks 51, and the telescopic ends of the electric push rods 50 drive the adjacent guide blocks 51 to move. The guide blocks 51 are sealed and matched with the adjacent filter shells 4. The guide blocks 51 are used to guide the solid impurities cleaned in the adjacent filter cloths 5. Two axially distributed receiving plates 52 are fixedly connected inside the support leg 1. The receiving plates 52 are slidably connected to the adjacent guide blocks 51, and the receiving plates 52 are fixed to the first fixed shell 2. The upper side of the guide block 51 is set to be conical, and the receiving plates 52 are provided with an inclined surface with the same inclination as the cone on the adjacent guide block 51. The receiving plates 52 and the adjacent guide blocks 51 cooperate with each other to jointly collect the solid impurities cleaned in the adjacent filter cloths 5.

[0038] When using the device to perform centrifugal separation operation on raw materials, the staff connects the feeding device to the upper end of the feeding pipe 7, and then the control terminal starts the power device on the upper side first, and the power device on the upper side drives the filter shell 4 on the upper side to rotate, and the filter shell 4 drives the adjacent filter cloth 5 to rotate synchronously. At the same time, the control terminal starts the transmission device on the lower side, and the transmission device drives the rotating tube 6 to rotate. The rotating tube 6 drives the connecting plate 9 to rotate synchronously through the transmission of the hydraulic oil in the liquid storage shell 8, and the connecting plate 9 drives the feeding pipe 7 to rotate synchronously, until the rotation speed of the feeding pipe 7, the liquid storage shell 8 and the upper filtering shell 4 reaches the specified rotation speed, the control terminal starts the feeding device, and the feeding device transports the raw materials into the feeding pipe 7.

[0039] After the feeding device is started at the control terminal, the feeding device transports the vinylene carbonate mixed solution (hereinafter referred to as raw material) into the discharge pipe 7. The raw material transported into the discharge pipe 7 flows outward through the rotating pipe 6 and the through holes on the upper side of the discharge pipe 7. At the same time, the flowing raw material is affected by the centrifugal force generated by the rotation of the rotating pipe 6 and the discharge pipe 7 and diffuses circumferentially, so that the distribution of the raw material in the filter shell 4 is more uniform. At the same time, the raw material flowing into the filter shell 4 is affected by the centrifugal force generated by the rotation of the filter shell 4, so that the solid impurities in the raw material in the filter shell 4 adhere to the inner wall of the upper filter cloth 5. At the same time, the liquid in the raw material passes through the upper filter shell 4 and the upper filter cloth 5 to flow into the first fixed shell 2 and flows out along the drainage hole on the first fixed shell 2. At the same time, the staff collects the flowing liquid to complete the centrifugal separation operation on the raw material.

[0040] In the above-mentioned process of centrifugal separation of raw materials, as the centrifugal time increases, the volume of impurities attached to the inner wall of the upper filter cloth 5 gradually increases, so that the thickness of the impurities on the inner wall of the upper filter cloth 5 gradually increases, and then the upper driving block 14 is rotated by the extrusion force, and the thickness of the impurities on the inner wall of the adjacent filter cloth 5 is detected by the upper driving block 14. During the rotation of the driving block 14, the driving block 14 drives the adjacent fixed rod 13 to rotate synchronously. At the same time, the fixed rod 13 drives the adjacent moving tube 11 to move upward through the transmission of the fixed column thereon. The moving tube 11 drives the adjacent first push plate 12 to move upward synchronously, and at the same time squeezes the hydraulic oil in the adjacent connecting shell 10 into the adjacent liquid storage tube 15, so that the adjacent second moving block 18 moves to the left.

[0041] During the process of the second moving block 18 moving to the left, the spring between it and the adjacent first moving block 17 is compressed and force is accumulated. Until the second moving block 18 moves to the left to a position in contact with the adjacent moving ring 21, the second moving block 18 drives the adjacent moving ring 21 to move to the left synchronously while continuing to move, and transports the hydraulic oil in the adjacent positioning ring 20 to the adjacent second fixed shell 22 through the connecting pipe, so that the adjacent second push plate 23 moves forward under the extrusion force, and the adjacent spring is compressed and force is accumulated. The second push plate 23 drives the adjacent limit block 24 to move forward synchronously. Until the moving ring 21 moves to the left to the extreme position, the adjacent second moving block 18 moves to the left to the extreme position synchronously, and at the same time, the spring between the second moving block 18 and the adjacent first moving block 17 is synchronously compressed to the extreme state.

[0042] When the second moving block 18 on the right side moves to the left to the extreme position, the second push plate 23 on the right side and the limit block 24 on the right side move forward to the extreme position synchronously, that is, the position where the limit block 24 on the right side loses contact with the first moving block 17, and then the first moving block 17 on the right side moves rapidly to the left under the action of the spring between it and the adjacent second moving block 18, and then the hydraulic oil in the right liquid storage pipe 15 is transported to the cavity on the right side of the lower part of the liquid storage shell 8 through the connecting pipe, so that the connecting plate 9 is rotated by the extrusion force, and the connecting plate 9 drives the discharge pipe 7 to rotate synchronously during the rotation process, so that the discharge pipe 7 and the rotating pipe 6 rotates relative to each other, thereby changing the connection relationship between the two groups of through holes on the feeding tube 7 and the two groups of through holes on the rotating tube 6 (that is, a group of through holes on the upper side of the feeding tube 7 and the adjacent through holes in a group on the upper side of the rotating tube 6 are misaligned with each other, and a group of through holes on the lower side of the feeding tube 7 and the adjacent through holes in a group on the lower side of the rotating tube 6 are connected to each other), until the spring between the first moving block 17 on the right and the adjacent second moving block 18 is extended to the initial state, and the first moving block 17 on the right is synchronously moved to the left to the extreme position, thereby allowing the raw materials flowing into the feeding tube 7 to be transported to the filter shell 4 on the lower side through the through holes between it and the lower side of the rotating tube 6.

[0043] When the first movable block 17 on the right side moves to the left, when the first movable block 17 moves to a position where it loses contact with the adjacent limit block 24, the second movable block 18 on the right side is squeezed by the hydraulic oil transported from the adjacent connecting shell 10 to the adjacent liquid storage pipe 15 and cannot be reset to the initial position, thereby maintaining the adjacent movable ring 21 at this position, making it impossible for the adjacent limit block 24 to be reset to the initial position.

[0044] During the rotation of the connecting plate 9, the connecting plate 9 transports the hydraulic oil in the upper left cavity of the liquid storage shell 8 to the left liquid storage tube 15 through the connecting pipe, so that the first moving block 17 on the left side moves to the left due to the extrusion force. During the movement, the first moving block 17 drives the second moving block 18 on the left side to move to the left synchronously through the adjacent spring. When the first moving block 17 on the left side moves to the left to the position in contact with the adjacent limit block 24, the first moving block 17 on the left side continues to move to the left, squeezing the inclined surface of the adjacent limit block 24, so that the limit block 24 on the left side drives the second moving block 18 on the left side to move to the left synchronously. The other parts connected thereto move forward synchronously and compress the adjacent springs to store force until the first moving block 17 on the left moves to the left to a position where it loses contact with the adjacent limit block 24. The limit block 24 on the left is reset to its initial position driven by the adjacent spring, and the hydraulic oil in the left liquid storage pipe 15 is transported to the left connecting shell 10, so that the first push plate 12 on the left moves downward under the extrusion force. The first push plate 12 drives the adjacent driving block 14 to rotate through the transmission of other parts connected thereto, so that the driving block 14 contacts the inner wall of the adjacent filter cloth 5.

[0045] After the first moving block 17 on the right side moves to the left to the extreme position, the control terminal starts the power device on the lower side, and the power device on the lower side drives the filter shell 4 on the lower side to rotate synchronously. At the same time, the control terminal reduces the rotation speed of the power device on the upper side, and the filter shell 4 on the lower side, a group of through holes on the lower side of the rotating tube 6 and a group of through holes on the lower side of the discharge tube 7 cooperate with each other to centrifuge the raw materials synchronously, so that the device can continue to work during the process of centrifuging the raw materials, thereby increasing the centrifugal effect of the device on the raw materials.

[0046] After the control terminal reduces the rotation speed of the upper power device, the control terminal starts the solenoid valve between the fixing part of the upper multi-stage telescopic rod 30 and the air pump, so that the fixing part of the upper multi-stage telescopic rod 30 is connected with the air pump, and the air pump is transported into the multi-stage telescopic rod 30 on the upper side, and the third push plate 31 in the telescopic end of the upper multi-stage telescopic rod 30 moves downward. The third push plate 31 stretches and stores force in the process of moving downward. At the same time, the third push plate 31 drives the adjacent connecting rod 32 to move downward synchronously in the process of moving downward. The connecting rod 32 is stretched by the adjacent multi-stage telescopic rod 30 in the process of moving downward. The connecting rod 32 is limited at the retracted end, and the connecting rod 32 rotates synchronously during the downward movement. The connecting rod 32 drives the adjacent scraper 34 to rotate synchronously during the rotation, until the vertical part of the upper limit groove on the connecting rod 32 moves to a position in contact with the telescopic end of the multi-stage telescopic rod 30, and the connecting rod 32 no longer drives the rotation during the continued movement, and the upper scraper 34 stops rotating synchronously. At this time, the scraper 34 is tightly fitted with the inner wall of the filter cloth 5. Subsequently, as the scraper 34 gradually moves downward, the scraper 34 cooperates with the upper filter cloth 5 to remove impurities attached to the inner wall of the filter cloth 5 for next use.

[0047] After the impurities on the inner wall of the upper filter cloth 5 are removed as mentioned above, the extrusion pressure of the upper filter cloth 5 on the adjacent driving block 14 is reduced, so that the extrusion pressure on other parts connected to it is reduced synchronously, and then the extrusion pressure on the spring in the second fixed shell 22 on the right side is gradually reduced. Therefore, the second push plate 23 on the left side can be reset backwards under the drive of the adjacent spring, and the second push plate 23 drives the adjacent limit block 24 to reset backward synchronously. During the resetting process of the second push plate 23, the hydraulic oil in the adjacent second fixed shell 22 is squeezed back into the adjacent positioning ring 20 by the second push plate 23 through the adjacent connecting pipe, and the adjacent moving ring 21 is restored to its initial position. The moving ring 21 drives the adjacent second moving block 18 to move a distance to the initial position. During the movement of the second moving block 18 on the right side, the hydraulic oil in the adjacent liquid storage pipe 15 is transported to the adjacent connecting shell 10, so that the first push plate 12 on the right side moves downward for a distance.

[0048] During the downward movement of the scraper 34, the telescopic end of the upper multi-stage telescopic rod 30 is gradually stretched, and at the same time, the elastic member 33 between the telescopic parts of each stage of the multi-stage telescopic rod 30 is stretched and force is accumulated, until the upper scraper 34 moves downward to the limit position, and the control terminal starts the air pump in reverse to reset the upper scraper 34 to the initial position, and shuts down the solenoid valve and the air pump between the fixed part of the upper multi-stage telescopic rod 30 and the air pump for next use.

[0049] In the process of removing impurities on the inner wall of the upper filter cloth 5 by the upper scraper 34, the control terminal starts the upper electric push rod 50, and the telescopic end of the electric push rod 50 drives the adjacent guide block 51 to move downward synchronously, so that the upper guide block 51 loses contact with the adjacent filter shell 4, and at the same time, the impurities cleaned on the inner wall of the upper filter cloth 5 fall on the guide block 51, and are guided by the conical surface of the upper guide block 51 to flow to the upper receiving plate 52, and the staff collects the impurities on the receiving plate 52 for subsequent processing.

[0050] After the impurities on the upper filter cloth 5 are cleaned, the staff will open the upper sealing cover 3 and clean the upper filter cloth 5. After cleaning, the staff will reinstall the upper sealing cover 3 on the upper filter shell 4, and the control terminal will synchronously reset the above-mentioned other parts to the initial position, wherein the resetting process of the first moving block 17 on the right side can refer to the process of the first moving block 17 on the left side moving to the left, in preparation for the next use, and the use process of the lower filter shell 4 can refer to the above. After using this device to complete the centrifugal separation operation on the raw material, the control terminal will reset the device to the initial position according to the above operation, and clean the used filter cloth 5 for subsequent use.

[0051] Embodiment 2: Considering that in the process of scraping impurities on the filter cloth by the existing device, since the material of the filter cloth is relatively soft, some impurities will still remain on the filter cloth during the cleaning process. In view of the above problem, the present invention proposes the following solution:

[0052] like Figure 4 and Figure 5 As shown, it also includes two axially distributed connecting frames 40, the two connecting frames 40 are detachably connected to the inside of adjacent filter cloths 5, and the connecting frames 40 are slidably connected to the rotating tube 6, and the two sealing covers 3 are commonly connected with an air supply pipe 41 through-type, the air supply pipe 41 is connected to the air pump, the air supply pipe 41 passes through the connecting frame 40 and is slidably connected thereto, and the air supply pipe 41 is fixedly connected with two axially distributed pneumatic telescopic rods 42, the telescopic ends of the pneumatic telescopic rods 42 are fixedly connected to the adjacent connecting frames 40, and the pneumatic telescopic rods 42 are used to drive the adjacent connecting frames 40 The pneumatic telescopic rod 42 is moved, and the stretching state of the adjacent filter cloth 5 is adjusted to shake off the impurities attached to the filter cloth 5. The fixed part of the pneumatic telescopic rod 42 is connected to the air pipe 41 through a connecting pipe. The air pump controls the telescopic ends of the two pneumatic telescopic rods 42 to move up and down through the air pipe 41 and the two connecting pipes, thereby controlling the two connecting frames 40 to move up and down. An electromagnetic valve is provided between the fixed part of the pneumatic telescopic rod 42 and the adjacent connecting pipe to change the connection state between the fixed part of the two pneumatic telescopic rods 42 and the air pipe 41.

[0053] After the upper scraper 34 moves downward to the extreme position, the control terminal closes the solenoid valve between the air pump and the fixed part of the upper multi-stage telescopic rod 30, and maintains the upper scraper 34 in this position. Then the control terminal opens the solenoid valve between the fixed part of the upper pneumatic telescopic rod 42 and the air pipe 41, and starts the air pump in reverse. The air pump extracts the gas in the fixed part of the upper pneumatic telescopic rod 42 through the air pipe 41, so that the telescopic end of the upper pneumatic telescopic rod 42 moves downward, and then the telescopic end of the upper pneumatic telescopic rod 42 drives the adjacent connecting frame 40 to move downward synchronously, and the upper connecting frame 40 drives the upper side of the adjacent filter cloth 5 to move downward synchronously, so that the filter cloth 5 is wrinkled.

[0054] After the telescopic end of the upper pneumatic telescopic rod 42 moves downward to the limit position, the control terminal starts the air pump in the positive direction, and the air pump transmits gas to the fixed part of the upper pneumatic telescopic rod 42 through the air supply pipe 41, so that the telescopic end of the upper pneumatic telescopic rod 42 moves upward, stretches the upper filter cloth 5, shakes off the impurities remaining on the filter cloth 5, and increases the cleaning efficiency of the filter cloth 5. The control terminal controls the upper filter cloth 5 through the air pump to repeat the above actions until the impurities remaining in the upper filter cloth 5 are cleaned. The control terminal resets the upper connecting frame 40 to the initial position and closes the solenoid valve between the fixed part of the upper pneumatic telescopic rod 42 and the air supply pipe 41. Then the control terminal reopens the solenoid valve between the air pump and the fixed part of the upper multi-stage telescopic rod 30. Then the control terminal extracts the gas in the fixed part of the upper multi-stage telescopic rod 30 through the air pump, and resets the upper scraper 34 to the initial position for subsequent use.
