Description

Technical Field

[0001] The present invention relates to the field of filtering technology, and more specifically, to a lithium carbonate filtering device. Background Art

[0002] Lithium carbonate, as a key inorganic compound, has broad application prospects. In the production process of lithium carbonate, filtration devices play a vital role, especially in the removal of solid particles and impurities in the solution, which is directly related to the purity and quality of the product.

[0003] Existing filtering devices are mostly composed of a filter kettle, a filter screen and an inspection port, and their working principle is as follows: first, the lithium carbonate solution to be filtered is poured into the interior of the filter kettle through the top of the filter kettle. Under the action of gravity, the solution falls downward, and in the process of falling, the solution reaches the filter screen, and solids and impurities will accumulate on the surface of the filter screen, and the liquid will continue to fall through the filter screen, thereby separating the solid and liquid of the solution, thereby achieving the filtering effect. When the solids and impurities accumulated on the surface of the filter screen reach a certain level, the inspection port can be opened to remove and replace the filter screen, and then the inspection port can be closed.

[0004] However, when the solids and impurities accumulated on the surface of the filter reach a certain amount, the solids and impurities are likely to clog the filter, hindering the smooth flow of the liquid. This blockage phenomenon not only causes the speed of liquid passing through the filter to slow down significantly, but may also cause local pressure to increase, placing unnecessary burden on the equipment. Secondly, whenever the filter needs to be replaced, the total process is divided into three steps, which requires opening the inspection port, replacing the filter, and then closing the inspection port. This process is relatively cumbersome and reduces work efficiency. Summary of the invention

[0032] 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.

[0033] See also Figure 1 - Figure 5As shown, a lithium carbonate filtering device comprises a wide filtering kettle 1 and a narrow filtering kettle 2, wherein the narrow filtering kettle 2 is fixedly connected to the top of the wide filtering kettle 1, and a narrow filtering net 3 is arranged inside the narrow filtering kettle 2, and further comprises:

[0034] A wide filter screen 4, which is arranged inside the wide filter kettle 1, and a connecting rod 5 is fixedly connected inside the narrow filter screen 3 and the wide filter screen 4, and a motor for providing power is installed at one end of the connecting rod 5, and the two ends of the connecting rod 5 respectively penetrate the wide filter kettle 1 and the narrow filter kettle 2, and extend to the outside of the wide filter kettle 1 and the narrow filter kettle 2;

[0035] Connecting plates 6, two pairs of connecting plates 6 are provided, and the two pairs of connecting plates 6 are rotatably connected to the outer sides of the two ends of a pair of connecting rods 5, and the top and bottom ends of the two pairs of connecting plates 6 are provided with fixing plates 7, and the fixing plates 7 are respectively fixedly connected to the outer sides of the wide filter kettle 1 and the narrow filter kettle 2, and a pair of first springs 8 are fixedly connected between the top and bottom ends of the connecting plates 6 and the pair of fixing plates 7, and the outer sides of the two ends of the pair of connecting rods 5 are sleeved with connecting double rings 9, and the outer sides of the pair of connecting double rings 9 are slidably connected with guide rings 10, and the pair of guide rings 10 are fixedly connected to the outer side of the wide filter kettle 1;

[0036] A linkage mechanism is provided between the pair of connecting rods 5, and the linkage mechanism is used for the pair of connecting rods 5 to rotate synchronously;

[0037] The periphery of the connecting rod 5 is provided with a shaking mechanism matched with the narrow filter screen 3 , and the shaking mechanism is used to vibrate the narrow filter screen 3 .

[0038] When the solids and impurities accumulated on the surface of the filter reach a certain amount, the solids and impurities are easy to clog the filter, hindering the smooth flow of the liquid. This clogging phenomenon not only causes the speed of the liquid passing through the filter to be significantly slowed down, but may also cause local pressure to increase, causing unnecessary burden on the equipment. When the embodiment of the present invention is in use, the lithium carbonate solution to be filtered is poured into the interior of the narrow filter kettle 2 through the top. Under the action of gravity, the lithium carbonate solution falls on the surface of the narrow filter mesh 3. The solids are blocked by the narrow filter mesh 3 and cannot pass through, while the liquid passes through the narrow filter mesh 3 smoothly, thereby realizing the filtration process of solid-liquid separation, and the liquid will eventually flow from the inside of the narrow filter kettle 2 into the inside of the wide filter kettle 1, and then flow from the bottom of the wide filter kettle 1 into When too many solids are accumulated on the surface of the narrow filter screen 3, the motor can be started. When the motor is running, it drives the upper connecting rod 5 to rotate 90 degrees, and the upper connecting rod 5 will drive the narrow filter screen 3 to rotate 90 degrees. At this time, the narrow filter screen 3 is in a vertical state, and the upper connecting rod 5 will synchronously drive the lower connecting rod 5 to rotate through the linkage mechanism during the rotation process, and when the lower connecting rod 5 is in the rotating state, it will drive the wide filter screen 4 to be in a horizontal state, and when the upper connecting rod 5 rotates, it will also drive the shaking mechanism to operate. When the shaking mechanism operates, it will move the position through the upper connecting rod 5 and the connecting plate 6, and in the process of moving the connecting plate 6, it will squeeze and stretch a pair of first elastic The spring 8 causes a pair of first springs 8 to deform and generate elastic potential energy. Under the cooperation of the shaking mechanism and the first spring 8, the upper connecting plate 6 will vibrate up and down, and the connecting plate 6 is then transmitted to the narrow filter screen 3 through the connecting rod 5, so that the narrow filter screen 3 is continuously shaken during the rotation, and the solids and impurities accumulated on the surface are shaken off, thereby avoiding the blockage of the narrow filter screen 3. Finally, the shaken solids fall on the surface of the wide filter screen 4, and in the process of the solid falling, the solids will hit the wide filter screen 4. The impact force of the fall will disperse some of the solids and let the liquid inside it flow out, so that the wide filter screen 4 can further realize the filtering function. Finally, the motor drives the upper connecting rod 5 to reverse and reset, and the connecting rod 5 The resetting will drive the narrow filter 3 to reset, and the lower connecting rod 5 will be reset through the linkage mechanism. The reset of the lower connecting rod 5 will drive the wide filter 4 to reset. At this time, the solids accumulated on the surface of the wide filter 4 will fall off when the wide filter 4 is reset to a vertical state, and when the upper connecting rod 5 is reset, the shaking mechanism will also operate accordingly. When the shaking mechanism drives the upper connecting rod 5 to move, the upper connecting rod 5 will drive the lower connecting rod 5 to move through the connecting double ring 9. When the lower connecting rod 5 moves, it cooperates with the first spring 8 below to synchronously realize the function of rotating and shaking the wide filter 4, so that the shaking generated by it will further shake off the solids attached to the surface of the wide filter 4, thereby improving the cleaning degree.

[0039] like Figure 3 and Figure 4 As shown, the linkage mechanism includes a first sprocket 11, a second sprocket 12 and a chain 13. The first sprocket 11 and the second sprocket 12 are respectively fixed to the outside of a pair of connecting rods 5. The first sprocket 11 is located directly above the second sprocket 12. The chain 13 is wound around the outside of the first sprocket 11 and the second sprocket 12 and meshes with the first sprocket 11 and the second sprocket 12.

[0040] When the connecting rod 5 located at the top rotates, it will drive the first sprocket 11 to rotate, and the rotation of the first sprocket 11 will drive the second sprocket 12 to rotate synchronously through the chain 13. When the second sprocket 12 rotates, it will drive the connecting rod 5 located at the bottom to rotate, thereby realizing the function of a pair of connecting rods 5 rotating synchronously in the same direction.

[0041] like Figure 1 and Figure 5 As shown, a blade 14 is fixedly connected to the outer side of the connecting rod 5 , and six groups of impellers 15 are rotatably connected to the outer sides of the blades 14 . A triangular block 16 is fixedly connected to the outer side of the wide filter kettle 1 , and the triangular block 16 is located between a pair of impellers 15 .

[0042] When the connecting rod 5 at the top rotates, it will also drive the blades 14 to rotate. During the rotation of the blades 14, the impeller 15 will be driven to contact and squeeze the inclined surface of the triangular block 16. Since the position of the triangular block 16 is fixed, the impeller 15 will be subjected to the reaction force from the triangular block 16, and the impeller 15 will move. The impeller 15 will then drive the blades 14 to move. During the movement of the blades 14, the connecting rod 5 at the top will be driven to move vertically upward. During the vertical movement of the connecting rod 5, it will be squeezed and stretched respectively through the connecting plate 6. The first spring 8 at the top and bottom ends of the connecting plate 6 causes the first spring 8 to deform and generate elastic potential energy. When the blade 14 rotates to drive the impeller 15 to break away from the squeezing of the triangular block 16, the first spring 8 stops being stressed and releases the elastic potential energy to drive the connecting rod 5 to reset through the connecting plate 6. When the upper connecting rod 5 moves up and down, it drives the narrow filter screen 3 to move, thereby realizing the shaking function. In addition, the upper connecting rod 5 will also drive the lower connecting rod 5 to synchronously realize the above-mentioned movement through the connecting double ring 9, thereby realizing the function of synchronous shaking of the wide filter screen 4.

[0043] like Figure 5 - Fig. 9As shown, a collecting plate 17 is provided inside the wide filter kettle 1, a card box 18 is fixedly connected to the outer side of the wide filter kettle 1, a pair of limit blocks 19 are fixedly connected to the outer side of the collecting plate 17, and the inner sides of the pair of limit blocks 19 are slidably connected with a first guide rod 20, and the two ends of the first guide rod 20 are respectively fixedly connected to the inner wall of the wide filter kettle 1 and the inner wall of the card box 18, and the outer sides of the pair of first guide rods 20 are sleeved with a second spring 21, one end of the second spring 21 is fixedly connected to the limit block 19, and the end of the second spring 21 away from the limit block 19 is fixedly connected to the inner wall of the card box 18, and a pulling mechanism that cooperates with the collecting plate 17 is provided on the outer side of the connecting rod 5, and an inspection groove is opened at the top of the card box 18, and a pair of shielding plates 22 are slidably connected to the top of the inspection groove, and an opening and closing mechanism that cooperates with the collecting plate 17 is provided on the periphery of the pair of shielding plates 22.

[0044] In the existing filter device, whenever the filter screen needs to be replaced, the entire filter device must be suspended to wait for the new filter screen to be installed. The production stagnation during this period not only increases the overall working time, but also directly reduces the working efficiency of the filtering process. When the embodiment of the present invention is in use, in the initial state, the collecting plate 17 is located inside the wide filter kettle 1, and the pulling mechanism has not yet started. The wide filter screen 4 is in a vertical state, and the solids and impurities accumulated on its surface will fall on the surface of the collecting plate 17 under the action of gravity. When the narrow filter screen 3 rotates to a vertical state, the wide filter screen 4 is in a horizontal state, and the impurities on the surface of the narrow filter screen 3 fall on the surface of the wide filter screen 4, and the wide filter When the net 4 rotates, it will drive the pulling mechanism to operate through the connecting rod 5 below, and the operation of the pulling mechanism will pull the collecting plate 17 to move in the direction of the card box 18, and when the collecting plate 17 moves, it will squeeze the second spring 21 through the limit block 19, so that the second spring 21 is deformed and generates elastic potential energy. When the collecting plate 17 enters the interior of the card box 18, the collecting plate 17 will drive the closing mechanism to operate, and the operation of the closing mechanism will open a pair of shutters 22. When the wide filter screen 4 is flipped 90 degrees to the horizontal direction, the collecting plate 17 is just inside the card box 18, and the shutter 22 is fully opened, and the inspection slot is fully exposed. At this time, the staff can inspect the collecting plate The surface of the narrow filter screen 3 and the wide filter screen 4 is cleaned. At this time, since the wide filter screen 4 is in a horizontal state, the solids will be isolated by the wide filter screen 4, thereby avoiding the situation where the solids directly fall and cannot be filtered. Through the above-mentioned structural design, the device can clean the solids and impurities accumulated on the surface of the narrow filter screen 3 and the wide filter screen 4 without stopping, thereby improving the practicality of the device and the efficiency of the cleaning work. Finally, when the narrow filter screen 3 and the wide filter screen 4 are reversed and reset, the wide filter screen 4 is again driven by the pulling mechanism to reset through the connecting rod 5 below. At this time, the pulling mechanism ends pulling the collection plate 17, and the second spring 21 releases its elastic potential energy. The positioning block 19 drives the collecting plate 17 to reset and return to the inside of the wide filter kettle 1 again. When the wide filter screen 4 is in a vertical state, the collecting plate 17 has just been reset. When the collecting plate 17 is reset, the squeezing of the closing mechanism by the collecting plate 17 is completely completed, and the closing mechanism will reset a pair of baffles 22 to close the inspection slot again to prevent external dust from entering. When the wide filter screen 4 is horizontal, the solids and impurities shaken off from the surface of the narrow filter screen 3 will be shaken off to the surface of the collecting plate 17 again when it is in a vertical state. Therefore, by repeating the above actions, the solids and impurities on the surfaces of the narrow filter screen 3 and the wide filter screen 4 can be cleaned without stopping the equipment.

[0045] like Figure 6 , Figure 7 and Figure 8As shown, the pulling mechanism includes a pulling wheel 23, a nylon rope 24, a guide tube 25 and a roller. The pulling wheel 23 is fixedly connected to the outer side of the connecting rod 5, one end of the nylon rope 24 is fixedly connected to the outer side of the pulling wheel 23, the end of the nylon rope 24 away from the pulling wheel 23 is fixedly connected to the outer side of the collecting plate 17, and the nylon rope 24 passes through the card box 18, the guide tube 25 is fixedly connected to the outer side of the wide filter kettle 1, the nylon rope 24 is slidably connected to the inside of the guide tube 25, the roller is fixedly connected to the outer side of the guide tube 25, and the nylon rope 24 is attached to the outer side of the roller.

[0046] When the wide filter screen 4 is turned over and drives the connecting rod 5 below to rotate, the connecting rod 5 will drive the pulling wheel 23 to rotate, and the rotation of the pulling wheel 23 will pull the nylon rope 24. The nylon rope 24 will pull the collection plate 17 when it is subjected to force, so that the collection plate 17 moves toward the card box 18, and the setting of the guide tube 25 and the roller limits the movement of the nylon rope 24 and guides the nylon rope 24 to move in the specified direction. It should be noted that the size of the pulling wheel 23 can ensure that when the connecting rod 5 below is rotated 90 degrees, the pulling wheel 23 rotates The collecting plate 17 can be reset by the second spring 21 through the limit block 19. During the reset of the collecting plate 17, the pulling wheel 23 reverses and the nylon rope 24 is reversed to make it easier for the nylon rope 24 to pull the collecting plate 17 next time.

[0047] like Figure 8 and Fig. 9 As shown, the opening and closing mechanism includes a pair of first L plates 26, a pair of second L plates 27, two pairs of guide plates 28, a pair of second limiting rods 29, two pairs of third springs 40 and a pair of inclined blocks 30. The pair of first L plates 26 and the pair of second L plates 27 are both fixedly connected to the top of the card box 18, the two pairs of guide plates 28 are respectively fixedly connected to the top of a pair of baffles 22, the two ends of a pair of second limiting rods 29 are respectively fixedly connected to the pair of first L plates 26 and the pair of second L plates 27, the second limiting rods 29 penetrate the guide plates 28, the two pairs of third springs 40 are respectively sleeved on the outside of the pair of second limiting rods 29, one end of the two pairs of third springs 40 are respectively fixedly connected to the two pairs of guide plates 28, the ends of the two pairs of third springs 40 away from the guide plates 28 are respectively fixedly connected to the pair of first L plates 26 and the pair of second L plates 27, the pair of inclined blocks 30 are respectively fixedly connected to the ends of a pair of baffles 22 away from the guide plates 28, and the pair of inclined blocks 30 are symmetrically arranged.

[0048] In the initial state, the pair of shields 22 are in a closed state. When the collecting plate 17 moves toward the card box 18, the collecting plate 17 will squeeze the pair of inclined blocks 30 during the movement. When the inclined surfaces of the pair of inclined blocks 30 are squeezed by the collecting plate 17 at this time, they will move, thereby driving the pair of shields 22 to move in the direction away from each other. During the movement of the shield 22, it will move along the outer side of the second limit rod 29 through the guide plate 28, and the guide plate 28 will squeeze the third spring 40, so that the third spring 40 is deformed and generates elastic potential energy. When the collecting plate 17 finishes moving, the collecting plate 17 squeezes the inclined blocks 30, so that The inclined block 30 drives the baffle 22 to completely open the inspection slot. It should be noted that the height of the pair of inclined blocks 30 is higher than the height of the second spring 21. Therefore, during the movement of the inclined block 30, the second spring 21 will not collide. When the collecting plate 17 is reset and separated from the interior of the card box 18, the collecting plate 17 gradually stops squeezing the inclined block 30, and the force on the third spring 40 gradually disappears, which will release the elastic potential energy and push the guide plate 28 to reset. The reset of the guide plate 28 will drive the baffle 22 and the inclined block 30 to reset. The reset of the baffle 22 will close the inspection slot again, and the reset of the inclined block 30 provides a basis for the next movement of the baffle 22.

[0049] like Fig.10 As shown, a pair of slide grooves 31 are provided inside the wide filter kettle 1 and the narrow filter kettle 2, and an isolation plate 32 is slidably connected inside the slide groove 31. The isolation plate 32 is made of rubber. The connecting rod 5 passes through the isolation plate 32, and arc strips 33 are fixed at both ends of the wide filter screen 4.

[0050] In order to prevent the internal liquid of the wide filter kettle 1 and the narrow filter kettle 2 from hitting the narrow filter screen 3 and the wide filter screen 4 when flowing down, and splashing out through the movable part of the connecting rod 5, when the embodiment of the present invention is used, a chute 31 is provided on the inner wall of the wide filter kettle 1 and the narrow filter kettle 2, and the isolation plate 32 slides inside the chute 31. At this time, when the connecting rod 5 moves vertically, it will drive the isolation plate 32 to move synchronously inside the chute 31. Moreover, the isolation plate 32 is made of rubber material, which can increase the sealing performance. The splashing liquid will be blocked by the isolation plate 32 and cannot leak out of the wide filter kettle 1 and the narrow filter kettle 2 through the movable part of the connecting rod 5.

[0051] Since the diameter of the narrow filter kettle 2 is half the diameter of the wide filter kettle 1, when the narrow filter screen 3 and the wide filter screen 4 rotate and tilt, the solids on the surface of the narrow filter screen 3 will begin to fall. At this time, the wide filter screen 4 has not yet turned completely horizontally, and the solids falling on the surface of the wide filter screen 4 will continue to fall along the tilt angle of the wide filter screen 4. The setting of the arc strip 33 can block the solids, and the solids are stuck at the corner of the arc strip 33 and the wide filter screen 4, thereby avoiding the falling of the solids. At the same time, the outer side of the arc strip 33 is arc-shaped, which can effectively avoid the arc strip 33 and the inner wall of the wide filter kettle 1 from getting stuck when the wide filter screen 4 rotates, thereby improving the smoothness of the device during operation.

[0052] Working principle: When the solids and impurities accumulated on the surface of the filter reach a certain amount, the solids and impurities are easy to block the filter, hindering the smooth flow of the liquid. This blockage phenomenon not only causes the speed of the liquid passing through the filter to be significantly slowed down, but may also cause local pressure to increase, causing unnecessary burden on the equipment. When the embodiment of the present invention is in use, the lithium carbonate solution to be filtered is poured into the interior of the narrow filter kettle 2 through the top. Under the action of gravity, the lithium carbonate solution falls on the surface of the narrow filter mesh 3. The solids are blocked by the narrow filter mesh 3 and cannot pass through, while the liquid passes through the narrow filter mesh 3 smoothly, thereby realizing the filtration process of solid-liquid separation, and the liquid will eventually flow from the inside of the narrow filter kettle 2 into the inside of the wide filter kettle 1, and then from the inside of the wide filter kettle 1 The bottom end flows into the designated position. When too many solids are accumulated on the surface of the narrow filter screen 3, the motor can be started. When the motor is running, it drives the connecting rod 5 located at the top to rotate 90 degrees, and the connecting rod 5 located at the top will drive the narrow filter screen 3 to rotate 90 degrees. At this time, the narrow filter screen 3 is in a vertical state, and the connecting rod 5 located at the top will synchronously drive the connecting rod 5 located at the bottom to rotate through the linkage mechanism during the rotation process. When the connecting rod 5 located at the bottom is in the rotating state, it will drive the wide filter screen 4 to be in a horizontal state. In addition, when the connecting rod 5 at the top rotates, it will also drive the shaking mechanism to operate. When the shaking mechanism operates, it will move the position through the upper connecting rod 5 and the connecting plate 6, and in the process of moving the connecting plate 6, it will squeeze and stretch a pair of The first spring 8 causes a pair of first springs 8 to deform and generate elastic potential energy. Under the cooperation of the shaking mechanism and the first spring 8, the upper connecting plate 6 will vibrate up and down, and the connecting plate 6 is then transmitted to the narrow filter screen 3 through the connecting rod 5, so that the narrow filter screen 3 is continuously shaken during the rotation, and the solids and impurities accumulated on the surface are shaken off, thereby avoiding the blockage of the narrow filter screen 3. Finally, the shaken solids fall on the surface of the wide filter screen 4, and in the process of the solid falling, the solids will hit the wide filter screen 4. The impact force of the fall will disperse some of the solids and let the liquid inside it flow out, so that the wide filter screen 4 can further realize the filtering function. Finally, the motor drives the upper connecting rod 5 to reverse and reset, and the connecting rod 5 is connected. When the rod 5 is reset, it will drive the narrow filter 3 to reset, and the lower connecting rod 5 will be reset through the linkage mechanism. The lower connecting rod 5 will reset and then drive the wide filter 4 to reset. At this time, the solids accumulated on the surface of the wide filter 4 will fall off when the wide filter 4 is reset to a vertical state. When the upper connecting rod 5 is reset, the shaking mechanism will also operate accordingly. When the shaking mechanism drives the upper connecting rod 5 to move, the upper connecting rod 5 will drive the lower connecting rod 5 to move accordingly through the connecting double rings 9. When the lower connecting rod 5 moves, it cooperates with the first spring 8 at the bottom to synchronously realize the function of rotating and shaking the wide filter 4, so that the shaking generated by it will further shake off the solids attached to the surface of the wide filter 4, thereby improving the cleaning degree.

[0053] When the connecting rod 5 at the top rotates, it drives the first sprocket 11 to rotate, and the rotation of the first sprocket 11 drives the second sprocket 12 to rotate synchronously through the chain 13, and when the second sprocket 12 rotates, it drives the connecting rod 5 at the bottom to rotate, thereby realizing the function of a pair of connecting rods 5 rotating synchronously in the same direction;

[0054] When the connecting rod 5 at the top rotates, it will also drive the blades 14 to rotate. During the rotation of the blades 14, the impeller 15 will be driven to contact and squeeze the inclined surface of the triangular block 16. Since the position of the triangular block 16 is fixed, the impeller 15 will be subjected to the reaction force from the triangular block 16, and the impeller 15 will move. The impeller 15 will then drive the blades 14 to move. During the movement of the blades 14, the connecting rod 5 at the top will be driven to move vertically upward. During the vertical movement of the connecting rod 5, it will be squeezed and stretched respectively through the connecting plate 6. The first spring 8 at the top and bottom of the connecting plate 6 is deformed and generates elastic potential energy. When the blade 14 rotates to drive the impeller 15 to break away from the extrusion of the triangular block 16, the first spring 8 stops being stressed and releases the elastic potential energy to drive the connecting rod 5 to reset through the connecting plate 6. When the upper connecting rod 5 moves up and down, it drives the narrow filter 3 to move, thereby realizing the shaking function. In addition, the upper connecting rod 5 also drives the lower connecting rod 5 to synchronously realize the above-mentioned movement through the connecting double ring 9, thereby realizing the synchronous shaking function of the wide filter 4.

[0055] In the existing filter device, whenever the filter screen needs to be replaced, the entire filter device must be suspended to wait for the new filter screen to be installed. The production stagnation during this period not only increases the overall working time, but also directly reduces the working efficiency of the filtering process. When the embodiment of the present invention is in use, in the initial state, the collecting plate 17 is located inside the wide filter kettle 1, and the pulling mechanism has not yet started. The wide filter screen 4 is in a vertical state, and the solids and impurities accumulated on its surface will fall on the surface of the collecting plate 17 under the action of gravity. When the narrow filter screen 3 rotates to a vertical state, the wide filter screen 4 is in a horizontal state, and the impurities on the surface of the narrow filter screen 3 fall on the surface of the wide filter screen 4, and the wide filter When the net 4 rotates, it will drive the pulling mechanism to operate through the connecting rod 5 below, and the operation of the pulling mechanism will pull the collecting plate 17 to move in the direction of the card box 18, and when the collecting plate 17 moves, it will squeeze the second spring 21 through the limit block 19, so that the second spring 21 is deformed and generates elastic potential energy. When the collecting plate 17 enters the interior of the card box 18, the collecting plate 17 will drive the closing mechanism to operate, and the operation of the closing mechanism will open a pair of shutters 22. When the wide filter screen 4 is flipped 90 degrees to the horizontal direction, the collecting plate 17 is just inside the card box 18, and the shutter 22 is fully opened, and the inspection slot is fully exposed. At this time, the staff can inspect the collecting plate The surface of the narrow filter screen 3 and the wide filter screen 4 is cleaned. At this time, since the wide filter screen 4 is in a horizontal state, the solids will be isolated by the wide filter screen 4, thereby avoiding the situation where the solids directly fall and cannot be filtered. Through the above-mentioned structural design, the device can clean the solids and impurities accumulated on the surface of the narrow filter screen 3 and the wide filter screen 4 without stopping, thereby improving the practicality of the device and the efficiency of the cleaning work. Finally, when the narrow filter screen 3 and the wide filter screen 4 are reversed and reset, the wide filter screen 4 is again driven by the pulling mechanism to reset through the connecting rod 5 below. At this time, the pulling mechanism ends pulling the collection plate 17, and the second spring 21 releases its elastic potential energy. The positioning block 19 drives the collecting plate 17 to reset and return to the inside of the wide filter kettle 1 again. When the wide filter screen 4 is in a vertical state, the collecting plate 17 is just reset. When the collecting plate 17 is reset, the squeezing of the closing mechanism by the collecting plate 17 is completely finished, and the closing mechanism will reset a pair of shielding plates 22 to close the inspection slot again to prevent external dust from entering. When the wide filter screen 4 is horizontal, the solids and impurities shaken off from the surface of the narrow filter screen 3 will be shaken off to the surface of the collecting plate 17 again when in a vertical state. Thus, by repeating the above actions, the solids and impurities on the surfaces of the narrow filter screen 3 and the wide filter screen 4 can be cleaned without stopping the equipment.

[0056] When the wide filter screen 4 is turned over and drives the connecting rod 5 below to rotate, the connecting rod 5 will drive the pulling wheel 23 to rotate, and the rotation of the pulling wheel 23 will pull the nylon rope 24. The nylon rope 24 will pull the collection plate 17 when it is subjected to force, so that the collection plate 17 moves toward the card box 18, and the setting of the guide tube 25 and the roller limits the movement of the nylon rope 24 and guides the nylon rope 24 to move in the specified direction. It should be noted that the size of the pulling wheel 23 can ensure that when the connecting rod 5 below is rotated 90 degrees, the pulling wheel 23 rotates The nylon rope 24 can be used to pull the collecting plate 17 to the bottom of the inspection port, so as to facilitate the cleaning of the inside of the collecting plate 17. When the connecting rod 5 below is reversed and reset, the pulling wheel 23 gradually stops pulling the nylon rope 24, and the force on the collecting plate 17 gradually stops. The second spring 21 will push the collecting plate 17 to reset through the limit block 19. During the reset of the collecting plate 17, the pulling wheel 23 is reversed to keep the nylon rope 24 in a taut state, so as to facilitate the pulling work of the nylon rope 24 on the collecting plate 17 next time.

[0057] In the initial state, the pair of shields 22 are in a closed state. When the collecting plate 17 moves toward the card box 18, the collecting plate 17 will squeeze the pair of inclined blocks 30 during the movement. When the inclined surfaces of the pair of inclined blocks 30 are squeezed by the collecting plate 17 at this time, they will move, thereby driving the pair of shields 22 to move in the direction away from each other. During the movement of the shield 22, it will move along the outer side of the second limit rod 29 through the guide plate 28, and the guide plate 28 will squeeze the third spring 40, so that the third spring 40 is deformed and generates elastic potential energy. When the collecting plate 17 finishes moving, the collecting plate 17 squeezes the inclined blocks 30, so that The inclined block 30 drives the shield 22 to completely open the inspection slot. It should be noted that the height of the pair of inclined blocks 30 is higher than the height of the second spring 21. Therefore, the inclined block 30 will not collide with the second spring 21 during its movement. When the collecting plate 17 is reset and separated from the inside of the card box 18, the collecting plate 17 gradually stops squeezing the inclined block 30. The force on the third spring 40 gradually disappears, and the elastic potential energy is released to push the guide plate 28 to reset. The reset of the guide plate 28 will drive the shield 22 and the inclined block 30 to reset. The reset of the shield 22 will close the inspection slot again, and the reset of the inclined block 30 provides a basis for moving the shield 22 next time.

[0058] In order to prevent the internal liquid of the wide filter kettle 1 and the narrow filter kettle 2 from hitting the narrow filter screen 3 and the wide filter screen 4 when flowing down, and splashing out through the movable part of the connecting rod 5, when the embodiment of the present invention is used, a chute 31 is provided on the inner wall of the wide filter kettle 1 and the narrow filter kettle 2, and the isolation plate 32 slides inside the chute 31. At this time, when the connecting rod 5 moves vertically, it will drive the isolation plate 32 to move synchronously inside the chute 31. Moreover, the isolation plate 32 is made of rubber material, which can increase the sealing performance. The splashing liquid will be blocked by the isolation plate 32 and cannot leak out of the wide filter kettle 1 and the narrow filter kettle 2 through the movable part of the connecting rod 5.

[0059] Since the diameter of the narrow filter kettle 2 is half the diameter of the wide filter kettle 1, when the narrow filter screen 3 and the wide filter screen 4 rotate and tilt, the solids on the surface of the narrow filter screen 3 will begin to fall. At this time, the wide filter screen 4 has not yet turned completely horizontally, and the solids that have fallen on the surface of the wide filter screen 4 will continue to fall along the tilt angle of the wide filter screen 4. The setting of the arc strip 33 can block the solids, and the solids are stuck at the corner of the arc strip 33 and the wide filter screen 4, thereby avoiding the falling of the solids. At the same time, the outer side of the arc strip 33 is arc-shaped, which can effectively avoid the arc strip 33 and the inner wall of the wide filter kettle 1 from getting stuck when the wide filter screen 4 rotates, thereby improving the smoothness of the device during operation.

[0060] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
