Description

Technical Field

[0001] This utility model belongs to the field of filter technology, and relates to a filter, particularly a self-cleaning directional filter. Background Technology

[0002] A filter is an indispensable device in pipelines transporting media. Water to be treated passes through the filter screen, where particulate impurities are trapped. The filtered water flows out from the outlet. This cycle continues, trapping more and more particles and slowing the filtration speed, while wastewater continues to flow in, causing the filter pores to become increasingly smaller.

[0003] A search revealed a Chinese patent document disclosing a filter with adjustable filtration direction [Application No.: 202320874990.6; Publication No.: CN 219744091 U]. This filter with adjustable filtration direction includes a sealing joint, with an internal thread fixing joint sleeved on one side. A filter screen is disposed between the sealing joint and the internal thread fixing joint. The sealing joint is an external thread joint. The internal thread fixing joint is provided with a fixing component that mates with a first flat surface. The fixing component includes a locking member fixedly connected to the internal thread fixing joint, and a set screw is threaded onto the locking member. This invention, by setting an external thread joint, a locking member, a set screw, and an internal thread fixing joint, with the set screw abutting against the external thread joint's wrench as a plane, and the curved surface of the locking member contacting the inner wall surface of the internal thread fixing joint, ensures that the external thread joint and the internal thread fixing joint do not loosen through the locking force of the set screw and the friction between the locking member and the internal thread fixing joint. This device has a compact structure, allows for quick assembly and disassembly, and is convenient for maintenance.

[0004] Although the patented structure is compact, quick to install and disassemble, and easy to maintain, impurities will accumulate inside the filter structure after long-term use, causing blockage of the filter screen and other filter components, thus reducing working efficiency. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a self-cleaning directional filter. The technical problem to be solved by this utility model is: how to physically brush away and clean the impurities adhering to the filter structure to achieve self-cleaning capability.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A self-cleaning directional filter includes a main cylinder and a connecting pipe threaded to the top of the main cylinder. An adjusting ring plate is rotatably connected inside the main cylinder, and a filter inner liner is fixed to the bottom of the adjusting ring plate. An adjusting annular cavity is formed inside the main cylinder, and a coil spring is installed within the adjusting annular cavity. A pushing block is fixed to one side of the adjusting ring plate, one end of the coil spring is fixedly connected to the pushing block, and the other end of the coil spring is fixedly connected to the cavity wall of the adjusting annular cavity. A mounting frame is fixed outside the main cylinder, and an adjusting component for rotating the adjusting ring plate is installed inside the mounting frame. A pair of arc-shaped plates are slidably connected inside the main cylinder, and a cleaning layer is fixed to the opposite surfaces of the arc-shaped plates. The cleaning layers of the two arc-shaped plates are in contact with the surface of the filter inner liner. A driving component for controlling the movement of the two arc-shaped plates is installed inside the main cylinder.

[0008] The working principle of this utility model is as follows: the control ring plate can be rotated by the control component, and the control ring plate can further rotate the filter inner tank. At this time, the filter inner tank is in a rotating state during the water flow process, which increases the contact area between the gaps of the filter inner tank and the water flow. The water flow carries away some of the debris adhering to the filter inner tank. Then, the drive component controls the two arc-shaped plates to contact the filter inner tank. At this time, the rotating surface of the filter inner tank will form friction with the cleaning layer, cleaning the filter inner tank and realizing the self-cleaning ability.

[0009] The control assembly includes a control block that is slidably connected to the surface of the main cylinder, a control motor fixed inside the mounting frame, a control screw that is rotatably connected inside the mounting frame, the output shaft of the control motor and the control screw being coaxially fixedly connected, and the control screw being threadedly connected to the control block. One end of a pull rope is fixed on the control block, and the other end of the pull rope is fixedly connected to the top surface of the control ring plate.

[0010] With the above structure, the control screw can be rotated by the control motor. After the control screw rotates, it will drive the control block to move, thereby pulling or releasing the pull rope. When the pull rope is pulled, the pull rope pulls the control ring plate to rotate. When the pull rope is released, the coil spring pushes the control ring plate to rotate in the opposite direction, thereby realizing the self-rotation capability of the filter inner tank and improving the overall cleaning efficiency.

[0011] The drive assembly includes a pair of bidirectional lead screws rotatably connected inside the main cylinder, and the threaded sections on both sides of the bidirectional lead screws are threadedly connected to the corresponding arc-shaped plates.

[0012] With the above structure, the rotation of the two-way lead screw can drive the two arc-shaped plates to move in opposite directions. When the two arc-shaped plates move in opposite directions, they will gradually come into contact with the filter inner liner. At this time, the rotation of the filter inner liner itself will clean the filter inner liner. When the two arc-shaped plates move in opposite directions, they will break away from the filter inner liner and will not affect the normal filtration work of the filter inner liner.

[0013] A drive motor is fixed inside the mounting frame, and an adjustment rod is rotatably connected inside the mounting frame. A drive gear is coaxially fixedly connected to the output end of the drive motor, and a transmission gear is coaxially fixedly connected to the middle of the adjustment rod. The drive gear meshes with the transmission gear, and both ends of the adjustment rod are coaxially fixedly connected to a first transmission bevel gear. A pair of second transmission bevel gears are rotatably connected inside the mounting frame. Both first transmission bevel gears mesh with their corresponding second transmission bevel gears, and connecting rods are coaxially fixedly connected to both second transmission bevel gears. One end of each connecting rod is coaxially fixedly connected to a corresponding double-acting lead screw.

[0014] With the above structure, the drive motor can drive the drive gear to rotate. After the drive gear rotates, it will drive the control rod to rotate through the transmission gear. After the control rod rotates, it will drive the first transmission bevel gear at both ends to rotate. After the first transmission bevel gear rotates, it will drive the second transmission bevel gear to rotate. The second transmission bevel gear will then drive the bidirectional lead screw to rotate through the connecting rod, thereby realizing the automatic fitting of the two arc plates.

[0015] Both the top end of the connecting pipe and the bottom end of the main tube are provided with connecting threads.

[0016] With the above structure, the filter can be connected to the pipeline via a connecting thread, thus achieving its normal filtration capacity.

[0017] Compared with existing technologies, this self-cleaning directional filter has the following advantages:

[0018] 1. The control ring plate is rotated by the control component, and the control ring plate further rotates the filter inner tank. At this time, the filter inner tank is rotating during the water flow process, which increases the contact area between the gaps of the filter inner tank and the water flow, and the water flow carries away some of the debris adhering to the filter inner tank.

[0019] 2. The two arc-shaped plates are controlled by the drive component to contact the filter inner tank. When the filter inner tank rotates, its surface will rub against the cleaning layer to clean the filter inner tank and achieve self-cleaning capability. Attached Figure Description

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1-4 As shown, a self-cleaning directional filter includes a main body cylinder 1 and a connecting pipe 2 threaded to the top of the main body cylinder 1. An adjusting ring plate 3 is rotatably connected inside the main body cylinder 1, and a filter inner liner 4 is fixed to the bottom of the adjusting ring plate 3. An adjusting annular cavity 5 is opened inside the main body cylinder 1, and a coil spring 6 is installed inside the adjusting annular cavity 5. A pushing block 7 is fixed to one side of the adjusting ring plate 3. One end of the coil spring 6 is fixedly connected to the pushing block 7, and the other end of the coil spring 6 is fixedly connected to the cavity wall of the adjusting annular cavity 5. An installation frame 8 is fixed outside the main body cylinder 1, and an adjusting component for rotating the adjusting ring plate 3 is installed inside the installation frame 8. A pair of arc-shaped plates 9 are slidably connected inside the main body cylinder 1. A cleaning layer 10 is fixed to the opposite surface of the arc-shaped plates 9. The cleaning layer 10 of the two arc-shaped plates 9 is in contact with the surface of the filter inner liner 4. A driving component for controlling the movement of the two arc-shaped plates 9 is installed inside the main body cylinder 1.

[0027] The control ring plate 3 can be rotated by the control component, and the control ring plate 3 can further rotate the filter inner tank 4. At this time, the filter inner tank 4 is in a rotating state during the water flow process, which increases the contact area between the gaps of the filter inner tank 4 and the water flow. The water flow carries away some of the debris adhering to the filter inner tank 4. Then, the two arc-shaped plates 9 are controlled by the drive component to contact the filter inner tank 4. At this time, the surface of the filter inner tank 4 rotates and forms friction with the cleaning layer 10, cleaning the filter inner tank 4 and realizing the self-cleaning ability.

[0028] The control assembly includes a control block 11 that is slidably connected to the surface of the main cylinder 1, a control motor 12 fixed inside the mounting frame 8, a control screw 13 that is rotatably connected inside the mounting frame 8, the output shaft of the control motor 12 and the control screw 13 being coaxially fixedly connected, and the control screw 13 being threadedly connected to the control block 11. One end of a pull rope 14 is fixed on the control block 11, and the other end of the pull rope 14 is fixedly connected to the top surface of the control ring plate 3.

[0029] With the above structure, the control screw 13 can be rotated by the control motor 12. After the control screw 13 rotates, it will drive the control block 11 to move, thereby pulling or releasing the pull rope 14. When the pull rope 14 is pulled, the pull rope 14 pulls the control ring plate 3 to rotate. When the pull rope 14 is released, the coil spring 6 pushes the control ring plate 3 to rotate in the opposite direction, thereby realizing the self-rotation capability of the filter inner tank 4 and improving the overall cleaning efficiency.

[0030] The drive assembly includes a pair of bidirectional lead screws 15 rotatably connected inside the main body cylinder 1, with the threaded sections on both sides of the bidirectional lead screws 15 being threadedly connected to the corresponding arc-shaped plates 9.

[0031] With the above structure, the rotation of the bidirectional lead screw 15 can drive the two arc plates 9 to move in opposite directions. When the two arc plates 9 move in opposite directions, they will gradually come into contact with the filter inner liner 4. At this time, the rotation of the filter inner liner 4 itself will clean the filter inner liner 4. When the two arc plates 9 move in opposite directions, they will break away from the filter inner liner 4 and will not affect the normal filtering work of the filter inner liner 4.

[0032] A drive motor 16 is fixed inside the mounting bracket 8. An adjustment lever 17 is rotatably connected inside the mounting bracket 8. A drive gear 18 is coaxially fixedly connected to the output end of the drive motor 16. A transmission gear 19 is coaxially fixedly connected to the middle part of the adjustment lever 17. The drive gear 18 meshes with the transmission gear 19. Both ends of the adjustment lever 17 are coaxially fixed with a first transmission bevel gear 20. A pair of second transmission bevel gears 21 are rotatably connected inside the mounting bracket 8. Both first transmission bevel gears 20 mesh with the corresponding second transmission bevel gears 21. Connecting rods 22 are coaxially fixedly connected to both second transmission bevel gears 21. One end of each connecting rod 22 is coaxially fixedly connected to a corresponding bidirectional lead screw 15.

[0033] With the above structure, the drive motor 16 can drive the drive gear 18 to rotate. After the drive gear 18 rotates, it will drive the control rod 17 to rotate through the transmission gear 19. After the control rod 17 rotates, it will drive the transmission bevel gear 20 at both ends to rotate. After the transmission bevel gear 20 rotates, it will drive the transmission bevel gear 21 to rotate. The transmission bevel gear 21 will further drive the bidirectional lead screw 15 to rotate through the connecting rod 22, thereby realizing the automatic fitting action of the two arc plates 9.

[0034] Both the top end of the connecting pipe 2 and the bottom end of the main body cylinder 1 are provided with connecting threads.

[0035] With the above structure, the filter can be connected to the pipeline via a connecting thread, thus achieving its normal filtration capacity.

[0036] The working principle of this utility model is as follows: When self-cleaning is required, the bottom interface of the main body cylinder 1 can be connected to the wastewater receiving pipe. At this time, the regulating motor 12 drives the regulating screw 13 to rotate. After the regulating screw 13 rotates, it will drive the regulating block 11 to move, thereby pulling or releasing the pull rope 14. When the pull rope 14 is pulled, the pull rope 14 pulls the regulating ring plate 3 to rotate. When the pull rope 14 is released, the coil spring 6 pushes the regulating ring plate 3 to rotate in the opposite direction, so that the contact area between the gap of the filter inner tank 4 and the water flow is increased. The water flow carries away some of the debris adhering to the filter inner tank 4, thereby realizing the self-rotation ability of the filter inner tank 4. Then, the drive motor 16 drives the drive gear 18 to rotate. The drive gear 18 rotates. Then, the control rod 17 will rotate via the transmission gear 19. After the control rod 17 rotates, it will drive the transmission bevel gear 20 at both ends to rotate. After the transmission bevel gear 20 rotates, it will drive the transmission bevel gear 21 to rotate. The transmission bevel gear 21 will then drive the double-acting screw 15 to rotate via the connecting rod 22. The rotation of the double-acting screw 15 will drive the two arc plates 9 to move relative to each other or in opposite directions. When the two arc plates 9 move relative to each other, they will gradually come into contact with the filter inner liner 4. At this time, in conjunction with the rotation of the filter inner liner 4 itself, the filter inner liner 4 will be cleaned. When the two arc plates 9 move in opposite directions, they will disengage from the filter inner liner 4 and will not affect the normal filtration operation of the filter inner liner 4.

[0037] In summary, the control ring plate 3 is rotated by the control component, and the control ring plate 3 further drives the filter inner tank 4 to rotate. At this time, the filter inner tank 4 is in a rotating state during the water flow process, which increases the contact area between the gaps of the filter inner tank 4 and the water flow. The water flow carries away some of the debris adhering to the filter inner tank 4. Then, the two arc-shaped plates 9 are controlled by the drive component to contact the filter inner tank 4. At this time, the surface of the filter inner tank 4 rotates and forms friction with the cleaning layer 10, cleaning the filter inner tank 4 and realizing the self-cleaning ability.
