[0002] Backwashing is a technique used to clean filtration systems. It mainly uses reverse flow of liquid or gas to flush out blockages in the filter media to restore filtration performance. It is commonly used in water treatment, industrial filtration, and air filtration, and is characterized by high efficiency and cleaning.

[0003] After backwashing, these impurities can be discharged along with the backwashing medium, forming wastewater containing pollutants. The wastewater can then be treated by a purification device for subsequent recycling, thus avoiding waste of water resources.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figure 1-5As shown, a backwash wastewater circulation and purification device includes a purification tank body 1; a first cover plate 11 is installed at the end of the purification tank body 1; a drain pipe 12 is installed on the top of the first cover plate 11; a movable block 13 is rotatably connected to the inner wall of the purification tank body 1; a filter screen 14 is fixedly connected to the end of the movable block 13, and the filter screen 14 is arc-shaped; a toothed groove 15 is opened on the side wall of the movable block 13; a motor 16 is installed on the top of the purification tank body 1; a gear 17 is fixedly connected to the output end of the motor 16, and the gear 17 and the toothed groove 15 are meshed with each other; during operation, after fixing the purification tank body 1 in the designated working area, the drain pipe 12 can be opened, and then an external infusion pipe is placed in the middle area of ​​the purification tank body 1, and wastewater is continuously injected into the purification tank body 1, so that after a long period of static purification, it is discharged through the first cover plate 11. When the wastewater is liquid, the falling wastewater can directly contact the arc-shaped filter screen 14. After solid-liquid separation, the solid residue can be transferred to both sides through the arc surface of the filter screen 14. When some residue is still on the surface of the filter screen 14, the operator can start the motor 16 switch, which causes the rotating gear 17 to drive the movable block 13 to rotate on the inner wall of the purification tank body 1. Under the action of the inertia of the filter screen 14, the residue remaining on the top of the filter screen 14 can be transferred to one side of the movable block 13. This step, combined with the arc-shaped filter screen 14, can reduce the problem of a large amount of scattered residue accumulating on the surface of the filter screen 14 for a long time during the initial filtration of wastewater, which would make it difficult for the operator to clean the filter screen 14 later. Moreover, the accumulation of more residue on the surface of the filter screen 14 can improve the filtration accuracy of the subsequently discharged wastewater. At the same time, under the action of the gear 17, the cleaning effect of the filter screen 14 can be accelerated.

[0026] like Figure 1-5As shown, a collection box 2 is provided on the inner wall of the movable block 13; multiple sets of drain holes 21 are opened in the middle of the movable block 13 and the collection box 2; two sets of support frames 22 are fixedly connected to the inner wall of the collection box 2, and the support frames 22 are slidably arranged in the middle of the purification tank body 1; a handle 23 is fixedly connected to the top of the support frame 22; two sets of frame plates 24 are installed on the top of the purification tank body 1; a second cover plate 25 is provided on the inner wall of the frame plate 24; during operation, by providing two sets of support frames 22 in the middle of the purification tank body 1, the residue transferred from the top of the filter screen 14 to both sides can be collected at the inner wall of the drain hole 21, and excess water can be transferred downward through the connected drain hole 21, and when the filter screen 14 rotates, the collection box supported by the support frame 22 is collected. The collection box 2 can slide on the inner wall of the movable block 13. After a lot of impurities are stored on the inner wall of the collection box 2, the staff can separate the two sets of second cover plates 25 from the frame plate 24 and pull the two sets of handles 23 upwards to completely separate the collection box 2 from the movable block 13 and gradually move it closer to the frame plate 24. At this time, the contact tool can discharge the impurities from the inner wall of the collection box 2. This step, combined with the up-and-down movement of the collection box 2, can discharge excess impurities and reduce the accumulation of impurities on the side wall of the filter screen 14, which may cause the filter screen 14 to get stuck when rotating on the inner wall of the purification tank body 1. At the same time, when the second cover plate 25 and the frame plate 24 are sealed, the airtightness between the purification tank body 1 and the outside can be improved, reducing the falling of some impurities.

[0027] like Figure 1-5 As shown, a rotating bead 3 is rotatably connected to the inner wall of the drain pipe 12; an elastic rope 31 is fixedly connected to the middle of the rotating bead 3; a sliding rod 32 is hinged to the end of the elastic rope 31, and the sliding rod 32 is slidably set in the middle of the filter screen 14; a counterweight ball 33 is fixedly connected to the bottom of the sliding rod 32; during operation, by providing the rotating bead 3 on the inner wall of the drain pipe 12, when the drain pipe 12 is opened, the elastic rope 31 can simultaneously pull the sliding rod 32 upward, and after continuously pulling the drain pipe 12, the counterweight ball 33 is pulled upward. The ball 33 continuously impacts the bottom of the filter screen 14, and when the filter screen 14 rotates, the slide bar 32, which is hinged to the elastic rope 31, can rotate with the filter screen 14. This step, by continuously pulling the drain pipe 12, allows the counterweight ball 33 to impact the inner wall of the filter screen 14 and treat the firmly attached impurities on its surface, further reducing the amount of impurities remaining on the top of the filter screen 14. Under the action of the rotating bead 3, the problem of the elastic rope 31 twisting and deforming when the filter screen 14 rotates can be reduced.

[0028] like Figure 1-5As shown, a support plate 4 is fixedly connected to the middle of the slide rod 32, and the support plate 4 is located at the bottom of the filter screen 14; multiple sets of cleaning brushes 41 are fixedly connected to the top of the support plate 4; during operation, by setting the support plate 4 in the middle of the slide rod 32, when the counterweight ball 33 moves upward, the soft material support plate 4 can deeply fit into the inner wall of the filter screen 14, and the protruding cleaning brushes 41 can unclog some of the holes in the inner wall of the filter screen 14. This step, under the action of the cleaning brushes 41, can improve the cleaning effect on the inner wall of the filter screen 14, and at the same time, the unfolded support plate 4 can also divert the falling liquid.

[0029] like Figure 1-5 As shown, a support plate 5 is fixed to the side wall of the filter screen 14; an elastic plate 51 is fixed to the middle of the support plate 5; multiple sets of baffles 52 are fixed to the inner wall of the purification tank body 1, and the baffles 52 are set close to the elastic plate 51. During operation, the elastic plate 51 is set on the inner wall of the filter screen 14. When the filter screen 14 rotates, the multiple sets of elastic plates 51 at its bottom can gradually approach the baffles 52. After the two come into contact, the middle of the elastic plate 51 will deform and then move away to reset. This step, combined with the elastic plate 51, can increase the overall vibration frequency of the filter screen 14 and accelerate the discharge of impurities from the top of the filter screen 14 under the action of vibration.

[0030] like Figure 1-5 As shown, a friction element 6 is fixedly connected to the middle of the handle 23. During operation, the friction element 6 is used in conjunction with the handle. When pulling the two sets of handles 23, the surface area of ​​the friction element 6 can be held directly. This step, in conjunction with the friction element 6, can reduce the problem of hand slippage when pulling the handle 23 and improve the stability of the grip.

[0031] Working principle: After fixing the purification tank body 1 in the designated working area, the drain pipe 12 can be opened. Then, the external infusion pipe is placed in the middle area of ​​the purification tank body 1, and wastewater is continuously injected into the purification tank body 1. After a long period of static purification, the wastewater is discharged through the first cover plate 11. When liquid is added into the purification tank body 1, the falling wastewater can directly contact the arc-shaped filter screen 14. After solid-liquid separation, the solid residue can be transferred to both sides through the arc surface of the filter screen 14. When some residue is still on the surface of the filter screen 14, the operator can start the motor 16. The gear 17 rotates, causing the movable block 13 to rotate along the inner wall of the purification tank body 1. Due to the inertia of the filter screen 14, residue remaining on the top of the filter screen 14 is transferred to one side of the movable block 13. Two sets of support frames 22 are provided in the middle of the purification tank body 1, allowing residue transferred from the top of the filter screen 14 to both sides to be collected on the inner wall of the drain hole 21. Excess water can be transferred downwards through the connected drain hole 21. When the filter screen 14 rotates, the collection box 2, supported by the support frame 22, can slide along the inner wall of the movable block 13. After the inner wall of the collection box 2 stores a large amount of impurities... Workers can separate the two sets of second cover plates 25 from the frame plate 24, and pull upwards by holding the two sets of handles 23, so that the collection box 2 is completely separated from the movable block 13 and gradually approaches the frame plate 24. At this time, the contact tool can discharge the impurities from the inner wall of the collection box 2. Because a rotating ball 3 is provided on the inner wall of the drain pipe 12, when the drain pipe 12 is opened, the elastic rope 31 can be used to pull the slide bar 32 upwards simultaneously. After the drain pipe 12 is pulled continuously, the counterweight ball 33 continuously hits the bottom of the filter screen 14. When the filter screen 14 rotates later, the slide bar 32 hinged to the elastic rope 31 can... As the filter screen 14 rotates, a support plate 4 is provided in the middle of the slide bar 32. When the counterweight ball 33 moves upward, the soft material support plate 4 can deeply fit into the inner wall of the filter screen 14, and the protruding cleaning brush 41 can unclog some of the holes in the inner wall of the filter screen 14. An elastic plate 51 is provided in the inner wall of the filter screen 14. When the filter screen 14 rotates, the multiple sets of elastic plates 51 at its bottom can gradually approach the position of the stop bar 52, so that the middle of the elastic plate 51 will deform after the two come into contact, and then move away and reset, cooperating with the friction element 6. When the two sets of handles 23 are pulled, the surface area of ​​the friction element 6 can be held directly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
