Description

Technical Field

[0001] This invention relates to the field of filters, specifically to a baffle-type dual filter and its usage method. Background Technology

[0002] The water curtain filter mainly consists of a body, filter screen, pressure cap, switching valve, sealing ring, bolts, etc.

[0003] In the prior art, when the filter filters water, water enters the interior of the filter through the inlet pipe and is filtered through the filter screen. When too many impurities are filtered out on the surface of the filter screen, the water can be cleaned by turning the switching valve to allow water to enter the interior of another set of filter tubes.

[0004] However, when the switching valve is worn out, and the valve baffle cannot fit completely against the inner wall of the pipe, the valve's sealing performance will be affected, resulting in water not being completely blocked into the other set of filter tubes. Summary of the Invention

[0005] The purpose of this invention is to provide a baffle-type dual filter and its usage method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a baffle-type dual filter, comprising:

[0007] The filter tube has a fixing port on its surface.

[0008] A connecting plate has a first rotating shaft on its surface, a swing rod on its surface, and a first screwing rod at its end. A second rotating shaft is located on the other side of the connecting plate, with a second screwing rod at its end. An extension block is located at the end of the second rotating shaft, a sleeve is located at the end of the extension block, and a partition is located at the end of the sleeve.

[0009] An air ring is placed on the surface of the partition.

[0010] Preferably, the filter tubes are provided in two sets, which are connected by a pipe. The surface of the pipe is provided with an inlet and an outlet. The connecting plate is screwed to the surface of the fixed port by a screw. A first rotating shaft is inserted into the surface of the connecting plate. The first rotating shaft can rotate on the surface of the connecting plate, and the swing rod rotates with the first rotating shaft.

[0011] Preferably, the end of the first rotating shaft is connected to the second rotating shaft, the second rotating shaft rotates with the first rotating shaft, the first screw rod is screwed inside the first rotating shaft, the end of the first screw rod is connected to the second screw rod, the second screw rod is located inside the second rotating shaft, the second screw rod rotates and moves with the first screw rod, and the second screw rod can move inside the second rotating shaft.

[0012] Preferably, an extension block is fixed to the end of the second rotating shaft. The extension block swings with the second rotating shaft. A sleeve tube is fitted to the end of the extension block. A slot is opened inside the sleeve tube. A spring is installed in the slot. One end of the spring is connected to the inner wall of the slot, and the other end is connected to the end of the extension block.

[0013] Preferably, a partition is fixed to the end of the sleeve tube, an air ring is fixed to the surface of the partition, the inside of the air ring is empty, a cavity is opened in the inner wall of the extension block, a transverse block is provided inside the extension block, the transverse block can move inside the extension block, a connecting pipe is connected to the surface of the extension block, the end of the connecting pipe is connected to the air ring, and the inside of the air ring communicates with the inside of the connecting pipe.

[0014] Preferably, the cavity communicates with the interior of the connecting pipe, allowing air in the cavity to enter the connecting pipe, and air in the connecting pipe to enter the interior of the inflation ring. A transverse groove is formed on the surface of the extension block.

[0015] A push rod is inserted into the transverse sliding groove, and the push rod can move within the transverse sliding groove.

[0016] Preferably, an arc-shaped plate is fixed to the end of the push rod, the arc-shaped plate is located inside the extension block, the second screw rod moves and abuts against the surface of the arc-shaped plate, and the arc-shaped plate moves and abuts against the surface of the transverse block. Preferably, a push ring is fixed to the surface of the push rod, a limit ring is fixed to the end of the push rod, a force-bearing block is fixed to the surface of the sleeve, the push rod is inserted into the inside of the force-bearing block, and the push ring and the limit ring are located on both sides of the force-bearing block.

[0017] Preferably, when the partition is in a vertical state, it blocks the inside of the pipe between the two sets of filter tubes. The partition is located on one side of the pipe, and after the partition swings with the second rotating shaft, it moves to the other side of the pipe.

[0018] A method for using a baffle-type dual filter includes the following steps:

[0019] Step 1: Maintain a seal. Water enters through the inlet and flows into the filter tubes, where it is filtered. The filtered water then exits through the outlet. When impurities inside a set of filter tubes need cleaning, rotate the swing rod. The swing rod drives the first rotating shaft to rotate, which in turn drives the partition to rotate, changing the direction of the partition's obstruction and allowing water to enter the other set of filter tubes for cleaning. Rotate the first rotating rod, which then drives the second rotating rod to move. After moving inside the first rotating shaft, the second rotating rod presses against the surface of the arc-shaped plate, causing the arc-shaped plate to move laterally. After the arc-shaped plate moves laterally, it presses against the surface of the transverse block, causing the transverse block to move inside the extension block. The movement of the transverse block compresses the air inside the cavity, allowing the air inside the cavity to enter the air ring through the connecting pipe, increasing the diameter of the partition and better maintaining a seal.

[0020] Step 2: Further sealing. The arc plate drives the push rod to move. The push rod moves in the transverse groove and drives the push ring to move. The push ring supports the force block, causing the sleeve tube to move the partition plate. This allows the partition plate to enter the depth of the connecting pipe between the two sets of filter tubes, further ensuring the sealing. In addition, a limit ring is set on the surface of the push rod to prevent the sleeve tube from falling off.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In this invention, water enters through the inlet and flows into the filter tubes, where it is filtered. The filtered water then exits through the outlet. When impurities inside one set of filter tubes need cleaning, the swing rod is turned, causing the first rotating shaft to rotate. This rotating shaft then rotates the partition, changing its blocking direction and allowing water to enter another set of filter tubes for cleaning. Turning the first turning rod causes the second turning rod to move. After moving inside the first rotating shaft, the second turning rod presses against the surface of the arc-shaped plate, causing the arc-shaped plate to move laterally. This laterally moves the arc-shaped plate against the surface of the lateral moving block, causing the lateral moving block to move inside the extension block. This movement compresses the air inside the cavity, allowing it to enter the inflation ring through the connecting pipe. This increases the diameter of the partition, improving sealing.

[0032] Example 1

[0033] Please see Figures 1-7 This invention provides a technical solution: a baffle-type dual filter, comprising: a filter tube 1, with a fixing port 2 on its surface; a connecting plate 5, with a first rotating shaft 6 on its surface, a swing rod 7 on its surface, a first screwing rod 8 at the end of the first rotating shaft 6, a second rotating shaft 13 on the other side of the connecting plate 5, a second screwing rod 14 at the end of the second rotating shaft 13, an extension block 19 at the end of the second rotating shaft 13, a sleeve tube 18 at the end of the extension block 19, and a partition 10 at the end of the sleeve tube 18; and an air ring 9 disposed on the surface of the partition 10. The first rotating shaft 6 drives the partition 10 to rotate, causing the partition 10 to change the direction of obstruction, allowing water to enter the interior of the other set of filter tubes 1, thus cleaning the impurities inside the filter tube 1. Tightening the first screwing rod 8 causes the first screwing rod 8 to drive the second screwing rod 14 to move.

[0034] Example 2

[0035] Based on Embodiment 1, two sets of filter tubes 1 are provided, and the two sets of filter tubes 1 are connected by a pipe. The surface of the pipe is provided with an inlet 3 and an outlet 4. The connecting plate 5 is screwed to the surface of the fixing port 2 by a screw. A first rotating shaft 6 is inserted into the surface of the connecting plate 5. The first rotating shaft 6 can rotate on the surface of the connecting plate 5. The swing rod 7 rotates with the first rotating shaft 6. Tightening the swing rod 7 causes the swing rod 7 to drive the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the partition 10 to rotate, so that the partition 10 changes the direction of obstruction.

[0036] The end of the first rotating shaft 6 is connected to the second rotating shaft 13. The second rotating shaft 13 rotates with the first rotating shaft 6. The first screw rod 8 is screwed inside the first rotating shaft 6. The end of the first screw rod 8 is connected to the second screw rod 14. The second screw rod 14 is located inside the second rotating shaft 13. The second screw rod 14 rotates and moves with the first screw rod 8. The second screw rod 14 can move inside the second rotating shaft 13. The first screw rod 8 drives the second screw rod 14 to move. After the second screw rod 14 moves inside the first rotating shaft 6, it abuts against the surface of the arc plate 25, causing the arc plate 25 to move laterally. After the arc plate 25 moves laterally, it abuts against the surface of the transverse block 24.

[0037] An extension block 19 is fixed to the end of the second rotating shaft 13. The extension block 19 swings with the second rotating shaft 13. A sleeve tube 18 is sleeved on the end of the extension block 19. A slot 22 is opened inside the sleeve tube 18. A spring 21 is installed in the slot 22. One end of the spring 21 is connected to the inner wall of the slot 22, and the other end is connected to the end of the extension block 19.

[0038] Example 3

[0039] Based on Embodiment 2, a partition 10 is fixed to the end of the sleeve 18, and an inflation ring 9 is fixed to the surface of the partition 10. The interior of the inflation ring 9 is hollow. A cavity 23 is formed in the inner wall of the extension block 19. A transverse block 24 is provided inside the extension block 19, and the transverse block 24 can move inside the extension block 19. A connecting pipe 12 is connected to the surface of the extension block 19, and the end of the connecting pipe 12 is connected to the inflation ring 9. The interior of the inflation ring 9 communicates with the interior of the connecting pipe 12. The transverse block 24 moves within the extension block. The internal movement of extension block 19 causes the transverse block 24 to move and compress the air inside cavity 23, allowing the air inside cavity 23 to enter the interior of inflation ring 9 through connecting pipe 12. Cavity 23 is connected to the interior of connecting pipe 12, and the air in cavity 23 can enter connecting pipe 12, and the air in connecting pipe 12 can enter the interior of inflation ring 9. A transverse groove 20 is provided on the surface of extension block 19, and a push rod 11 is inserted into the transverse groove 20. The push rod 11 can move in the transverse groove 20.

[0040] An arc-shaped plate 25 is fixed to the end of the push rod 11. The arc-shaped plate 25 is located inside the extension block 19. After the second screw rod 14 moves, it presses against the surface of the arc-shaped plate 25. After the arc-shaped plate 25 moves, it presses against the surface of the transverse block 24. After the second screw rod 14 moves inside the first rotating shaft 6, it presses against the surface of the arc-shaped plate 25, causing the arc-shaped plate 25 to move laterally. After the arc-shaped plate 25 moves laterally, it presses against the surface of the transverse block 24, causing the transverse block 24 to move inside the extension block 19. After the transverse block 24 moves, it compresses the air inside the cavity 23, causing the air inside the cavity 23 to enter the interior of the inflation ring 9 through the connecting pipe 12.

[0041] Example 4

[0042] Based on Embodiment 3, a push ring 15 is fixed to the surface of the push rod 11, and a limit ring 17 is fixed to the end of the push rod 11. A force-bearing block 16 is fixed to the surface of the sleeve tube 18. The push rod 11 is inserted into the inside of the force-bearing block 16. The push ring 15 and the limit ring 17 are located on both sides of the force-bearing block 16. When the partition 10 is in a vertical state, it blocks the inside of the pipe between the two sets of filter tubes 1. The partition 10 is located on one side of the pipe. After the partition 10 swings with the second rotating shaft 13, it moves to the other side of the pipe. The push rod 11 drives the push ring 15 to move. The push ring 15 holds the force-bearing block 16, so that the sleeve tube 18 drives the partition 10 to move, so that the partition 10 enters the depth of the pipe connecting the two sets of filter tubes 1, further ensuring the sealing performance.

[0043] In actual use, water enters through inlet 3 and flows into the filter tube 1. The water is filtered inside the filter tube 1, and the filtered water is discharged from outlet 4. When impurities inside one set of filter tubes 1 need to be cleaned, the swing rod 7 is turned, causing the first rotating shaft 6 to rotate. The first rotating shaft 6 then rotates the baffle 10, changing the direction of obstruction and allowing water to enter the other set of filter tubes 1 for cleaning. Turning the first turning rod 8 causes the second turning rod 14 to move. After moving inside the first rotating shaft 6, the second turning rod 14 presses against the surface of the arc-shaped plate 25, causing the arc-shaped plate 25 to move laterally. The rear support is held on the surface of the transverse block 24, causing the transverse block 24 to move inside the extension block 19. After the transverse block 24 moves, it squeezes the air inside the cavity 23, causing the air inside the cavity 23 to enter the interior of the inflation ring 9 through the connecting pipe 12, which increases the diameter of the partition 10 and better maintains the sealing performance. The arc plate 25 drives the push rod 11 to move. The push rod 11 moves in the transverse groove 20 and drives the push ring 15 to move. The push ring 15 supports the force block 16, causing the sleeve tube 18 to drive the partition 10 to move, so that the partition 10 enters the depth of the connecting pipe of the two sets of filter tubes 1, further ensuring the sealing performance. The surface of the push rod 11 is provided with a limit ring 17 to prevent the sleeve tube 18 from falling off.
