Description

Technical Field

[0001] The present application relates to the technical field of filtration equipment, and in particular to a secondary filtration equipment. Background Art

[0002] With the continuous upgrading of industrial processes, the gradual sophistication of products, and the protection and attention to the environment, the market has put forward higher requirements for filtration. Filtration is not only required to ensure the effect, but also the efficiency of filtration is getting higher and higher.

[0003] Especially in the environment of processing small precision workpieces, it is not enough to filter it through a gantry filter once. There are still some small impurities in the cleaning liquid after filtration. The impurities will affect the processing of small precision bearings, thereby affecting the quality of the product and causing economic losses. Utility Model Content

[0004] In order to improve the filtering effect and reduce the impact of impurities in the cleaning fluid on the precision of the workpiece when processing small precision workpieces, the present application provides a secondary filtering device.

[0005] The secondary filtration equipment provided in this application adopts the following technical solution:

[0006] A secondary filtration device includes a filter box and a bracket for supporting the filter box, a sealing cover is provided on the filter box, a filter cartridge is rotatably provided in the filter box, a plurality of through holes are provided on the peripheral side wall of the filter cartridge, a rotating shaft is fixedly connected to the filter cartridge, a motor is fixedly installed on the outer side wall of the filter box, and the motor is fixedly connected to the rotating shaft; a filter groove is provided on the inner wall of the filter box, and a filter cloth is installed in the filter groove; an input pipe and an output pipe are installed on the filter box, a connecting pipe is installed on the filter cartridge, and the input pipe is inserted into the connecting pipe; a secondary filter pipe is installed on the output pipe.

[0007] By adopting the above technical solution, the liquid to be filtered flows from the input pipe into the filter box, and then through the connecting pipe into the filter cartridge. Driven by the motor, the filter cartridge rotates rapidly, and the liquid in the filter cartridge rotates with it, generating centrifugal force. When the particulate matter in the rotating liquid is subjected to the centrifugal force, due to its large mass, it is also subjected to a large centrifugal force. Therefore, under the action of centrifugal force, these particulate matter moves outward from the rotation axis, eventually falling onto and being deposited on the filter cloth. The clarified liquid seeps through the filter cloth and flows out to the bottom of the filter box, flowing from the output pipe into the secondary filter tube. After secondary filtration, it can flow into the next stage, thereby improving the filtration effect, reducing the impurity content in the liquid, and thus reducing the impact of impurities on product processing and quality, thereby reducing economic losses.

[0008] Preferably, a support rod is fixedly connected to the filter cartridge, a slide groove is provided on the inner wall of the filter box, and the support rod is slidably connected to the inner wall of the slide groove.

[0009] By adopting the above technical solution, when the motor drives the filter cartridge to rotate, the support rod rotates in the chute following the filter cartridge, thereby increasing the support effect on the filter cartridge and reducing the possibility of the filter cartridge shaking during rotation.

[0010] Preferably, two connecting rods are provided in the filter tank, the two connecting rods are magnetic and attract each other, the two ends of the filter cloth are fixedly clamped on the two connecting rods, a clamping groove is provided on the connecting rod, and a clamping assembly for clamping the end of the filter cloth in the clamping groove is provided on the connecting rod.

[0011] By adopting the above technical solution, when the impurity adsorption on the filter cloth is saturated, the staff needs to replace the filter cloth. At this time, the staff needs to open the sealing cover, take out the connecting rod from the filter tank, release the fixed connection of the clamping assembly to the filter cloth, and then replace the new filter cloth and fix the two ends of the filter cloth to the two connecting rods through the clamping assembly. Then, the two connecting rods are placed in the filter tank. Then, the staff moves one of the connecting rods to abut against the other connecting rod, so that the filter cloth surrounds the inner wall of the filter box, thereby avoiding folding and stacking of the filter cloth.

[0012] Preferably, the clamping assembly includes a clamping plate and a driving rod, the clamping plate is slidably connected to the inner wall of the clamping groove, and the driving rod is threadedly connected to the clamping plate.

[0013] By adopting the above technical solution, when the staff needs to replace the filter cloth, the staff rotates the driving rod, and the driving rod rotates to drive the clamping plate away from the filter cloth, so that the staff can drive the saturated filter cloth, and then put the end of the new filter cloth into the clamping groove, and then rotate the driving rod to drive the clamping plate close to the filter cloth, and press the filter cloth against the inner wall of the clamping groove, thereby fixing the filter cloth.

[0014] Preferably, a rubber pad is fixedly connected to the sealing cover, and the rubber pad is squeezed into the filter tank and abuts against the connecting rod.

[0015] By adopting the above technical solution, when the sealing cover is closed, the rubber pad on the sealing cover can abut against and restrict the connecting rod, thereby reducing the possibility of the connecting rod moving.

[0016] Preferably, one side of the sealing cover is hinged to the filter box, and a fixed block is fixedly connected to the other side of the sealing cover. The filter box is provided with a fixing groove for the fixing block to be inserted, and a plug rod is inserted and slid in the fixing groove. The fixed block is provided with a slot for the plug rod to be inserted, and a pull block is fixedly connected to the plug rod. A first spring is sleeved on the plug rod, and both ends of the first spring are respectively fixedly connected to the outer side wall of the filter box and the side wall of the pull block.

[0017] By adopting the above technical solution, when the staff rotates the sealing cover to close it, the fixed block on the sealing cover is inserted into the fixed groove, the staff pulls the pull block to stretch the first spring to move, and the insertion rod follows the pull block to move away from the fixed block. When it is detached from the fixed block, the fixed block is completely inserted into the fixed groove under the action of gravity. At this time, the staff releases the pull block, and the insertion rod is pushed into the slot by the elastic force of the first spring, thereby limiting the position of the fixed block and fixing the sealing cover.

[0018] Preferably, an abutment block slides in the fixed groove, the abutment block abuts against the insertion rod, a second spring is provided in the fixed groove, the two ends of the second spring are respectively fixedly connected to the abutment block and the inner wall of the fixed groove, and the fixed block abuts against the abutment block.

[0019] By adopting the above technical solution, before the fixed block is inserted into the fixed slot, the abutment block abuts against the insertion rod and the insertion rod drives the pulling block to stretch the first spring. When the staff pulls the sealing cover and inserts the fixed block into the fixed slot, the fixed block abuts and pushes the abutment block to compress the second spring to move. When the abutment block compresses the second spring to move, the insertion rod slides and is connected to the side wall of the fixed block until it is inserted into the slot; when the staff needs to open the sealing cover, the staff pulls the pulling block, and the pulling block drives the insertion rod away from the slot. At this time, the abutment block pushes the fixed block away from the fixed slot under the elastic force of the second spring. The staff releases the pulling block and the insertion rod abuts against the abutment block, which makes it convenient for the staff to open the sealing cover.

[0020] Preferably, the secondary filter tube is threadedly connected to the output tube, and a filter medium is provided inside the secondary filter tube.

[0021] By adopting the above technical solution, when the liquid in the filter box is collected at the bottom of the filter box after centrifugal filtration and flows out from the output pipe, it is filtered again through the secondary filter tube, thereby enhancing the filtration effect. The threaded connection also makes it convenient for the staff to remove the secondary filter tube to replace the filter medium therein.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The liquid to be filtered flows from the inlet pipe into the filter box, and then through the connecting pipe into the filter cartridge. Driven by the motor, the filter cartridge rotates rapidly, and the liquid in the filter cartridge rotates with the filter cartridge, generating centrifugal force. When the particulate matter in the rotating liquid is subjected to the centrifugal force, due to its large mass, the centrifugal force it is subjected to is also large. Therefore, under the action of centrifugal force, these particulate matter moves toward the outside of the rotating axis, eventually falling onto and depositing on the filter cloth. The clarified liquid seeps through the filter cloth and flows out to the bottom of the filter box, flowing from the outlet pipe into the secondary filter tube. After secondary filtration, it can flow into the next stage, thereby improving the filtration effect, reducing the impurity content in the liquid, and thus reducing the impact of impurities on product processing and quality, thereby reducing economic losses.

[0024] 2. When the motor drives the filter cartridge to rotate, the support rod rotates with the filter cartridge in the chute, thereby increasing the support for the filter cartridge and reducing the possibility of the filter cartridge shaking during rotation;

[0025] 3. When the impurities on the filter cloth are saturated with adsorption, the staff needs to replace the filter cloth. At this time, the staff needs to open the sealing cover, take out the connecting rod from the filter tank, release the fixed connection of the clamping assembly to the filter cloth, and then replace the new filter cloth and use the clamping assembly to fix the two ends of the filter cloth to the two connecting rods respectively, and then put the two connecting rods into the filter tank. Then, the staff moves one of the connecting rods to abut against the other connecting rod, so that the filter cloth surrounds the inner wall of the filter box, thereby preventing the filter cloth from folding and stacking.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a secondary filtration device, such as Figure 1 and Figure 2 As shown, the filter box 1 includes a filter box 1 and a bracket 29 for supporting the filter box 1. A sealing cover 2 is hingedly mounted on the top of the filter box 1. A filter cartridge 3 is rotatably mounted within the filter box 1. Multiple through-holes 4 are formed in the sidewalls of the filter cartridge 3. A rotating shaft 5 is fixedly welded to the bottom of the filter cartridge 3. A motor 6 is fixedly mounted on the outer sidewall of the bottom of the filter box 1. The motor 6 is fixedly welded to the rotating shaft 5. When the motor 6 is activated, it drives the filter cartridge 3 to rotate, thereby facilitating the centrifugal force to remove solid particles and other impurities from the liquid. A filter slot 7 is formed on the inner wall of the filter box 1, and a filter cloth 8 is installed in the filter slot 7. An inlet pipe 9 is threadedly connected to the top of the filter box 1. A connecting pipe 11 is fixedly mounted on the top of the filter cartridge 3. The inlet pipe 9 can be inserted into the connecting pipe 11. When the sealing cover 2 is closed, a worker rotates the inlet pipe 9 so that the inlet pipe 9 extends downward and inserts into the connecting pipe 11, thereby allowing the liquid to be filtered to be fed into the filter cartridge 3 through the inlet pipe 9. When the worker needs to open the sealing cover 2 to replace the filter cloth 8, the worker rotates the inlet pipe 9 to disengage the connecting pipe 11, thereby preventing the opening of the sealing cover from being affected.

[0035] like Figure 1 and Figure 2As shown, the bottom of the filter cartridge 3 is welded with multiple support rods 13, evenly distributed around the filter cartridge 3. A circular chute 14 is defined on the inner wall of the bottom side of the filter housing 1. The bottom of the support rods 13 is slidably connected to the inner wall of the chute 14. When the motor 6 drives the filter cartridge 3 to rotate, the support rods 13 rotate with the filter cartridge 3 within the chute 14, thereby increasing support for the filter cartridge 3 and reducing the possibility of the filter cartridge 3 shaking during rotation. The bottom of the filter housing 1 is connected to the output pipe 10, to which a secondary filter tube is threadedly connected. The secondary filter tube is padded with an adsorbent filter medium. The liquid to be filtered flows from the input pipe 9 into the filter housing 1, and then through the connecting pipe 11 into the filter cartridge 3. Driven by the motor 6, the filter cartridge 3 rotates rapidly, and the liquid inside the filter cartridge 3 rotates with it, generating centrifugal force. When the particulate matter in the rotating liquid is subjected to the centrifugal force, due to its large mass, it is also subjected to a large centrifugal force. Therefore, these particulate matter moves to the outside of the center of the rotating shaft 5 under the action of centrifugal force, and finally falls into and deposits on the filter cloth 8, while the clarified liquid seeps out of the filter cloth 8 and gathers at the bottom of the filter box 1; the liquid in the output pipe 10 flows into the next stage through the secondary filter pipe, and then flows into the next stage after secondary filtration, thereby improving the filtration effect, reducing the impurity content in the liquid, and further reducing the impact of impurities on product processing and quality, thereby reducing economic losses.

[0036] like Figure 2 and Figure 3 As shown, combined with Figure 4 As shown, two connecting rods 15 are placed in the filter tank 7. The connecting rods 15 can be removed from the filter tank 7. The two connecting rods 15 have magnetic properties on the opposite side walls and attract each other. The two ends of the filter cloth 8 are fixedly clamped on the two connecting rods 15. A lower retaining ring 31 is provided at the bottom of the filter tank 7, and an upper retaining ring is provided at the top of the filter tank 7. The upper retaining ring and the lower retaining ring 31 limit the connecting rods 15 from tilting toward the filter cartridge 3. The lower retaining ring 31 is fixedly welded to the bottom wall of the filter tank 7, and the upper retaining ring is welded to the lower retaining ring 31 via a fixing rod 30. A clamping groove 18 is provided on the connecting rod 15, and a clamping assembly 16 for clamping the end of the filter cloth 8 in the clamping groove 18 is provided on the connecting rod 15; the clamping assembly 16 includes a clamping plate 17 and a driving rod 19, and the driving rod 19 is a small screw. The clamping plate 17 is threadedly connected to the driving rod 19, and the clamping plate 17 is slidably connected to the inner wall of the clamping groove 18. A rubber pad 20 is fixedly adhered to the bottom of the sealing cover 2. The rubber pad 20 is ring-shaped and squeezed into the filter tank 7 and abuts against the connecting rod 15 and the filter cloth 8.

[0037] like Figure 2 and Figure 3 As shown, combined with Figure 4As shown, when the impurities on the filter cloth 8 are saturated with adsorption, the staff needs to replace the filter cloth 8. At this time, the staff needs to open the sealing cover 2, remove the connecting rod 15 from the filter tank 7, and then rotate the driving rod 19 to drive the clamping plate 17 away from the filter cloth 8, so that the saturated filter cloth 8 can be removed. Then, the end of the new filter cloth 8 is placed into the clamping groove 18, and then the driving rod 19 is rotated to drive the clamping plate 17 close to the filter cloth 8. Then, the staff folds the filter cloth 8 and simultaneously inserts the two connecting rods 15 into the filter tank 7. Then, the staff moves one of the connecting rods 15 around the filter tank 7 to unfold the filter cloth 8 and attract it to abut against the other connecting rod 15, so that the filter cloth 8 surrounds the inner wall of the filter box 1, thereby preventing the filter cloth 8 from folding and piling up. Afterwards, the staff closes the sealing cover 2, and the rubber pad 20 on the sealing cover 2 abuts against the top of the connecting rod 15 and the filter cloth 8, thereby reducing the possibility of the connecting rod 15 moving.

[0038] like Figure 2 and Figure 5 As shown, one side of the sealing cover 2 is hinged to the filter box 1, and a fixing block 21 is fixedly welded on the other side of the sealing cover 2. A fixing groove 22 for the fixing block 21 to be inserted is provided on the filter box 1 in the vertical direction. An abutment block 27 is slidably provided in the fixing groove 22 in the vertical direction. A second spring 28 is provided in the fixing groove 22 in the vertical direction. The two ends of the second spring 28 are fixedly welded to the lower end surface of the abutment block 27 and the inner wall of the bottom of the fixing groove 22. A plug rod 23 is penetrated and slidably provided on the inner wall of the fixing groove 22. One end of the plug rod 23 is penetrated out of the filter box 1 and is fixedly welded with a pull block 25. A first spring 26 is sleeved on the plug rod 23. The first spring 26 is arranged in the horizontal direction. The two ends are respectively fixedly welded to the pulling block 25 and the outer wall of the filter box 1. The side wall of the fixed block 21 is provided with a slot 24 for the insertion of the rod 23 in the horizontal direction. Before the fixed block 21 is inserted into the fixed groove 22, the abutment block 27 abuts against the rod 23 and makes the first spring 26 in an extended state. When the staff closes the sealing cover 2, the fixed block 21 on the sealing cover 2 is pushed by the staff and inserted into the fixed groove 22, and abuts and pushes the abutment block 27 to compress the second spring 28 to move. When the abutment block 27 compresses the second spring 28 downward and moves, the rod 23 slides and is connected to the side wall of the fixed block 21 until the rod 23 aligns with the slot 24 and is inserted into the slot 24 under the action of the first spring 26. When the staff needs to open the sealing cover 2, the staff pulls the pull block 25, and the pull block 25 drives the insertion rod 23 away from the slot 24. At this time, the abutment block 27 pushes the fixed block 21 away from the fixed slot 22 under the elastic force of the second spring 28. The staff releases the pull block 25 and the insertion rod 23 abuts against the abutment block 27, making it easier for the staff to open the sealing cover 2.

[0039] The working principle of the embodiment of the present application is as follows: the liquid to be filtered enters the filter box 1 through the input pipe 9, and then enters the filter cartridge 3 through the connecting pipe 11. The filter cartridge 3 rotates rapidly under the drive of the motor 6. The liquid in the filter cartridge 3 rotates with the filter cartridge 3 and generates centrifugal force. When the particulate matter in the rotating liquid is subjected to the centrifugal force, due to its large mass, the centrifugal force it is subjected to is also large. Therefore, under the action of the centrifugal force, these particulate matter moves toward the outside of the center of the rotating shaft 5, and eventually falls on and is deposited on the filter cloth 8, while the clarified liquid permeates through the filter cloth 8 and flows out to collect at the bottom of the filter box 1; the liquid in the output pipe 10 flows into the next stage, passes through the secondary filter pipe, and then flows into the next stage after secondary filtration, thereby improving the filtration effect, reducing the impurity content in the liquid, and further reducing the impact of impurities on product processing and quality, thereby reducing economic losses.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
