Description

Technical Field

[0001] The invention relates to the technical field of filter stations, and in particular to a backwashing high-pressure filter station. Background Art

[0002] Backwash filter station is a kind of equipment that can operate under high pressure, filter fluids, and automatically backwash to clean the filter medium. It is generally used in industrial, municipal and agricultural fields.

[0003] Among them, the Chinese invention patent, with the publication number of CN119280956A, is a super-large flow high-pressure automatic backwashing filter station. When cleaning impurities on the semicircular filter plate, the two blocks can be moved out from the corresponding discharge holes respectively by using the cooperation of the controller and two sets of electric push rods, and then the paddle can be swung left and right by using the cooperation of the controller, the motor body, the box plate with holes, the box body and the rotating rod. Then, the impurities on the semicircular filter plate can be pushed to the inside of the two discharge holes by using the cooperation of the left and right swinging paddle. Then, the impurities can be diverted away by using the cooperation of two guide shells and two auxiliary holes. However, there are certain defects in actual use. When some impurities and foreign matter are large in size, it is difficult to remove them through the discharge holes, which can easily cause larger foreign matter to continue to exist in the semicircular filter plate.

When the sealing plate 7 and the filter bin 16 are in an open and closed setting, as the rotating shaft 14 rotates, the scraper 18 fixedly connected to the rotating shaft 14 pushes the filtered residue in the filter bin 16, and can push part of the residue to be discharged through the guide hopper 17, so as to achieve the effect of simultaneous filtration and timely discharge, and prevent the problem of clogging of the filter holes in the filter bin 16 due to long-term filtration and failure to discharge the debris in the filter bin 16 in time.

[0038] A connecting frame 10 is fixedly connected to the side of the outer wall of the station body 2 away from the sealing plate 7, a sliding block 33 is slidably connected to the lower surface of the connecting frame 10, a connecting block 28 is fixedly connected to the lower surface of the sliding block 33, a screw rod 34 is fixedly connected to the inner wall of the connecting frame 10, the screw rod 34 passes through the sliding block 33 and is screwed thereto, a motor 35 for driving the screw rod 34 to rotate is fixedly installed on the outer wall of the connecting frame 10, the output end of the motor 35 passes through the connecting frame 10 and is connected to the screw 34, the connecting block 28 is penetrated and fixedly connected with a push rod 27, the push rod 27 passes through the station body 2 and is fixedly connected with the movable block 23, and the end of the movable block 23 is rotationally connected to the shaft end of the unloading plate 15 in a limited position;

[0039] In this embodiment: At one end of the discharge plate 15 near the movable block 23, there is a movable sleeve that is rotationally limited to the movable block 23. An annular groove is provided on the outer contour of the movable sleeve. Starting the first motor 35 can drive the screw 34 to rotate, so that the screw 34 drives the sliding block 33 to move. The connecting block 28 fixedly connected to the sliding block 33 pushes the second push rod 27 to move. The second push rod 27 pushes the discharge plate 15 to move through the movable block 23, so that the discharge plate 15 can discharge materials.

[0040] A first connecting frame 10 passes through and is slidably connected to a sliding seat 11 fixedly connected to the connecting block 28. On both sides of the sliding seat 11, there are fixedly connected second connecting frames 12. At one end of the second connecting frame 12 away from the sliding seat 11, there is fixedly connected a first push rod 13. The first push rod 13 passes through the station body 2 and is fixedly connected to the arc-shaped square pipe 20. The second connecting frame 12 pushes the first push rod 13 to move into the station body 2. The arc-shaped square pipe 20 fixedly connected to the first push rod 13 moves at the bottom of the filter chamber 16 to perform reverse flushing on the bottom of the filter chamber 16 to prevent the filter holes from being blocked.

[0041] Near the connection with the filter chamber 16 on the inner wall of the material guiding hopper 17, there is a baffle 31 rotatably connected. The baffle 31 is rotatably connected to the inner wall of the material guiding hopper 17 through a rotating shaft 14. On one side of the baffle 31, there is fixedly connected a connecting rod 30. On the side of the connecting rod 30 away from the baffle 31, there is an electric push rod 22. The telescopic end of the electric push rod 22 is movably connected to the connecting rod 30. On the inner wall of the station body 2, there is fixedly connected a connecting piece 32. The connecting piece 32 is rotatably connected to the end of the electric push rod 22 through a pin shaft;

[0042] In this embodiment: The telescopic end of the electric push rod 22 is fixedly connected with a movable joint. The movable joint is vertically movably connected to the connecting rod 30 through a pin shaft. Starting the electric push rod 22, the telescopic end of the first push rod 13 pushes the baffle 31 to rotate, so that the material guiding hopper 17 is communicated with the filter chamber 16. When the rotating shaft 14 rotates in the filter chamber 16, the scraper 18 sweeps the filtered sundries into the material guiding hopper 17. On the contrary, the telescopic end of the first push rod 13 pushes the baffle 31 to rotate, so that the material guiding hopper 17 is closed with the filter chamber 16. By driving the rotation of the rotating shaft 14 and the scraper 18, the automatic pushing of the residues and the directional discharge of the material guiding hopper 17 are realized. Combined with the opening and closing of the baffle 31 controlled by the electric push rod 22, the discharge channel can be dynamically adjusted to avoid secondary blockage caused by the accumulation of residues. By controlling components such as the first motor 35 and the electric push rod 22 through the PLC, the whole process of unloading, flushing, and discharging is automated. Only need to start the preset program without frequent manual intervention, which conforms to the trend of modern industrial intelligence.

[0043] Discharge ports 4 are provided on both sides of the outer wall of the base 1, and the end of the guide hopper 17 close to the discharge port 4 is inclined and extends into the discharge port 4. Collection boxes 8 cooperating with the discharge port 4 are placed on both sides of the station body 2 on the base 1, and the discharged residues are collected with the assistance of the collection boxes 8 and the discharge port 4.

[0044] The two ends of the arc-shaped square tube 20 are fixedly connected with a nozzle 26 near the side directly below the guide hopper 17. The bottom of the guide hopper 17 is provided with evenly distributed filtering holes. A connector 21 is provided on the bottom side of the arc-shaped square tube 20 near the center. The end of the nozzle 26 corresponds to the bottom side of the guide hopper 17. The connector 21 is connected to the delivery pump through a hose. When the arc-shaped square tube 20 moves along the guide rod 19, the nozzle 1 25 on the arc-shaped square tube 20 flushes the bottom direction of the filter bin 16. The nozzle 1 25 is tilted toward the front of the discharge plate 15 to ensure that the nozzle 1 25 can always flush the bottom of the filter bin 16 in front of the discharge plate 15 when the discharge plate 15 moves, so that the discharge plate 15 can automatically remove the residue in the filter bin 16, thereby improving the efficiency of removing the residue in the filter bin 16. The nozzle 1 25 and the nozzle 2 26 are arranged at the bottom of the filter bin 16. The high-pressure reverse flushing combined with the mechanical push of the discharge plate 15 can effectively remove the residue in the filter hole, thereby avoiding the blockage problem caused by the accumulation of impurities in the traditional filtering method.

[0045] In this embodiment: the surface at the center of the discharge plate 15 is fixedly connected with a sleeve 29 axially slidingly connected to the rotating shaft 14, the surface of the discharge plate 15 is provided with an opening groove adapted to the scraper 18, and the surface of the station body 2 close to the sealing plate 7 is fixedly connected with two symmetrically arranged limit posts 24, the two limit posts 24 penetrate the sealing plate 7 and are slidably connected to the sealing plate 7, and a spring is sleeved on the limit post 24 to resist the sealing plate 7;

[0046] The spring can make the sealing plate 7 automatically reset. When the unloading plate 15 moves, the sleeve 29 pushes the sealing plate 7 to separate from the opening at the end of the filter bin 16, which is convenient for discharging. After discharging, the spring automatically resets the sealing plate 7 to ensure the sealing of the filter bin 16. The end of the limit column 24 is fixedly connected with a block that resists the spring. As the unloading plate 15 moves in the filter bin 16, automatic unloading is performed. The sleeve 29 on the unloading plate 15 moves toward the sealing plate 7. The sleeve 29 pushes the sealing plate 7 to separate from the opening at the end of the filter bin 16. The residue in the filter bin 16 can be automatically discharged under the push of the unloading plate 15, which can prevent the residue from continuing to accumulate in the filter bin 16 and clogging the filter holes on the filter bin 16, thereby affecting the filtering effect.

[0047] The top of the filter bin 16 passes through the top of the station body 2 and is fixedly connected to the top cover 3. The upper surface of the top cover 3 is connected with a delivery pipe 9. A drain outlet is provided at the bottom of the station body 2. The drain outlet of the station body 2 is connected to the water inlet of the filter 6 through a pipeline. The filter 6 further filters the post-processed water after the preliminary filtration, so as to achieve the effect of precision filtration. The filter 6 can be selected as a high-precision filter of model PQXFA-100. The preliminary filtration of the filter bin 16 and the subsequent high-precision such as PQXFA-100 form a multi-stage processing system, which can effectively intercept particles harmful to the hydraulic system.

[0048] The inner wall of the filter bin 16 is fixedly connected to two symmetrically arranged sliding rods 36, the two sliding rods 36 penetrate and are horizontally slidably connected to a mounting plate 37, one side of the mounting plate 37 is fixedly connected to a connecting seat 38, the surface of the mounting plate 37 is connected to a deflection bar 2 40 by fixed axis rotation, the surface of the deflection bar 2 40 is fixedly connected to a connecting column 42, the end of the connecting column 42 away from the discharge plate 15 is fixedly connected to a deflection bar 1 39, the surface of the deflection bar 1 39 is fixedly connected to a nozzle 3 41 through a column, and the end of the connecting seat 38 away from the mounting plate 37 is fixedly connected to the discharge plate 1 5 is fitted with a connecting plate 45, and an arc groove for the column to penetrate is opened on the surface of the connecting plate 45. The nozzle three 41 is connected to the external pump body through a hose. The hose is provided to prevent the nozzle three 41 from interfering when the mounting plate 37 moves. The nozzle three 41 is provided with a plurality of nozzles and extends to the surface of the discharge plate 15. When the deflection bar 2 40 is reciprocated, the connecting column 42 and the deflection bar 1 39 fixedly connected thereto can drive the nozzle three 41 to reciprocate and deflect, so as to wash the surface of the discharge plate 15 and prevent residual foreign matter from adhering to the surface of the discharge plate 15.

[0049] The lower surface of the connecting seat 38 is connected with a rotating bar 43 for fixed axis rotation. The rotating bar 43 is penetrated and vertically limited and slidably connected with a movable rod 44. The connecting column 42 penetrates the movable rod 44 and is fixedly connected to the deflection bar 39. The unloading plate 15 is located between the deflection bar 39 and the connecting plate 45. The surface of the unloading plate 15 close to the deflection bar 39 is provided with radial strips. The upper surface of the connecting seat 38 is fixedly installed with a motor 3. The output end of the motor 3 is connected to the rotating bar 43, driving the rotating bar 43 to rotate, pushing the movable rod 44 to move along the connecting column 42 and pushing the connecting column 42 to swing. When the unloading plate 15 moves, it can push the connecting seat 38 to rotate. The connecting plate 45 enables the mounting plate 37 to move as a whole along with the discharge plate 15, and increases the friction force through the deflection strip 39 and the radial strip patterns on the surface of the discharge plate 15, so as to push the discharge plate 15 to deflect back and forth. When the discharge plate 15 moves, the scraper 18 can be slightly deflected to sweep the debris remaining in the filter bin 16, so that it can be better moved toward the sealing plate 7 for discharge, thereby improving the efficiency of cleaning the debris remaining in the filter bin 16, and at the same time, it can effectively prevent the residual foreign matter from sticking to the surface of the discharge plate 15, ensure the cleanliness of the discharge plate 15, and reduce the equipment failure or subsequent operation problems caused by the residual foreign matter.

[0050] In summary, by setting up the unloading mechanism, a filter bin 16 is set in the station body 2, and the bottom end of the filter bin 16 is semicircular and evenly distributed filter holes are opened on the arc-shaped contour, which can perform preliminary filtration on the larger particles of waste in the filter bin 16, effectively intercept large particles of impurities, and reduce the burden of subsequent filtration. In the unloading mechanism, the arc-shaped square tube 20 moves at the bottom of the filter bin 16, and the nozzle 25 on the arc-shaped square tube 20 can reversely flush the bottom of the filter bin 16, effectively preventing the filter holes from being blocked. While reversely flushing, it can assist the unloading plate 15 in discharging, thereby improving the discharging efficiency;

[0051] The two sides of the filter chamber 16 are connected with guide hoppers 17. As the shaft 14 rotates, the scraper 18 fixedly connected to the shaft 14 pushes the residue filtered by the filter chamber 16. Some residues can be discharged through the connection between the guide hopper 17 and the filter chamber 16, achieving the effect of simultaneous filtration and timely discharge, avoiding the problem of clogging of the filter hole due to long-term filtration and failure to discharge debris in time.

[0052] When the sealing plate 7 is separated from the end of the filter bin 16, the unloading plate 15 moves along the inner wall of the filter bin 16 in the station body 2 to discharge larger debris in time, further preventing the occurrence of blockage and ensuring the normal operation of the filter station. The backwashing high-pressure filter station integrates the functions of preliminary filtration, backwashing, unloading and debris collection, which can effectively prevent the filter holes from being blocked, ensure the filtering effect, and improve the stability and reliability of the equipment operation.
