A V-type filter tank water inlet distribution device

Abstract

This utility model discloses a V-shaped filter water inlet distribution device, including a filter body, an installation box on the drainage side of the filter body, symmetrical hangers on both sides of the inner wall of the filter body, a rotating water distribution mechanism below the hangers, and sealing components on both sides of the rotating water distribution mechanism. This utility model has a simple structure and reasonable design, improving the structure of the traditional V-shaped channel. When the filter holes become clogged, the internal filter plate can be reversed in time, and the blockage can be cleared by water pressure backwashing. This ensures that the sewage can be evenly distributed on the lower filter media layer and avoids blockage in the V-shaped channel, achieving long-term stable operation of the V-shaped filter and better meeting the actual use requirements of the current V-shaped filter. At the same time, after the filter plate is rotated and adjusted, the drainage channel on the other side is simultaneously sealed by the sealing flap. The whole process is linked through structural design, with good continuity.

Description

Technical Field

[0001] This utility model relates to the technical field of V-type filter equipment, specifically a V-type filter inlet water distribution device. Background Technology

[0002] V-type filters, a type of high-efficiency water treatment filtration equipment, are named for the V-shaped structure of their two inlet tanks. They are widely used in waterworks and sewage treatment plants. Their core advantage lies in the use of constant water level and constant velocity filtration technology, combined with air-water backwashing process, which features high filtration speed, long filtration cycle, and good effluent quality.

[0003] The shortcomings of existing technology:

[0004] Currently, the common V-type filter structure mainly includes a V-shaped inlet trough, a filter media layer, and a water and air distribution system. The V-shaped trough is typically made of concrete or stainless steel, with multiple filter holes at the bottom for evenly distributing the incoming water and aiding in surface cleaning. However, the filter holes in existing V-shaped troughs are easily clogged by suspended solids, algae, or silt, leading to uneven effluent distribution, affecting the filtration efficiency of the filter media layer below, and ultimately impacting the stable operation of the filter. Utility Model Content

[0005] The purpose of this invention is to provide a V-type filter water inlet distribution device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a V-shaped filter water inlet distribution device, comprising a filter body, an installation box provided on the drainage side of the filter body, brackets symmetrically arranged on both sides of the inner wall of the filter body, a rotating water distribution mechanism provided below the brackets, and sealing components provided on both sides of the rotating water distribution mechanism.

[0007] The rotating water distribution mechanism includes:

[0008] A rotating shaft is symmetrically and movably arranged on both sides of the filter body, and a filter plate is arranged above the rotating shaft;

[0009] The mounting bracket is located below the hanging bracket. The arc-shaped part at the lower end of the mounting bracket is sleeved on the outside of the rotating shaft and rotatably connected to the rotating shaft. The filter plate can only rotate inside the mounting bracket. Both sides of the mounting bracket are inclinedly provided with drainage grooves that match the filter plate.

[0010] The drive unit is located inside the mounting box on the drain side of the filter body;

[0011] A level gauge, which is mounted on the inner wall of the mounting bracket.

[0012] Preferably, the enclosure component includes:

[0013] A sealing flap is symmetrically and movably arranged on both sides of the mounting frame, and the upper end of the sealing flap is rotatably connected to the upper opening of the drainage groove.

[0014] Two sealing rods are provided on the outside of the rotating shaft to press the sealing flap onto the corresponding drainage groove. The arc-shaped part at the lower end of the mounting bracket slides in a staggered manner with the two sealing rods through a groove.

[0015] Preferably, the driving unit includes:

[0016] The motor is mounted on the side wall of the filter body, and the output end of the motor is provided with a first bevel gear;

[0017] The second bevel gear is disposed at the end of the rotating shaft located on the outside of the filter body and meshes with the first bevel gear.

[0018] Preferably, a limiting strip is provided on the outer side of the groove opening of the drainage trough to limit the opening angle of the sealing flap.

[0019] Preferably, the included angle of the drainage grooves on both sides of the mounting bracket is 60-90 degrees.

[0020] Preferably, the included angles between the two sealing rods and the filter plate are equal to the included angles between the drainage grooves on both sides.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This V-type filter inlet water distribution device, by setting a rotating water distribution mechanism, including a rotating shaft, filter plates, mounting frame, drainage trough, drive unit and level gauge, improves the structure of the traditional V-type trough. When the filter holes inside become blocked, the internal filter plates can be reversed in time, and the blockage can be cleared by water pressure backwashing. This ensures that the sewage can be evenly distributed on the lower filter media layer, and also avoids blockage in the V-type trough. This achieves long-term stable operation of the V-type filter and is more in line with the actual use requirements of the current V-type filter.

[0023] 2. This V-shaped filter water inlet distribution device, by setting a sealing component, including a sealing flap and two sealing pressure rods, realizes that after the filter plate is rotated and adjusted, the sealing flap can be used to seal the drainage tank on the other side simultaneously. The whole process is linked through structural design, with good continuity, and the structure is simple and convenient for later maintenance. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified. Example

[0034] Please see Figure 1-5 As shown, this utility model provides a technical solution for a V-type filter inlet water distribution device: A V-type filter inlet water distribution device includes a filter body 1, an installation box 2 welded to the drainage side of the filter body 1, and brackets 3 symmetrically installed on both sides of the inner wall of the filter body 1. A rotating water distribution mechanism 4 is installed below the brackets 3, and sealing components 5 are also installed on both sides of the rotating water distribution mechanism 4. The rotating water distribution mechanism 4 includes a rotating shaft 401, an installation bracket 403, a drive unit 405, and a level gauge 406. The rotating shaft 401 is symmetrically and movably installed on both sides of the filter body 1 and rotatably connected to the side walls of the filter body 1 through sealed bearings. A filter plate 402 is installed above the rotating shaft 401. The mounting bracket 403 is installed below the hanger 3. The arc-shaped part at the lower end of the mounting bracket 403 is fitted onto the outside of the rotating shaft 401 and is rotatably connected to the rotating shaft 401. The filter plate 402 can only rotate inside the mounting bracket 403. Drainage grooves 404 matching the filter plate 402 are inclinedly opened on both sides of the mounting bracket 403. The drive unit 405 is installed on the drainage side of the filter body 1 and is located inside the mounting box 2. The level gauge 406 is installed on the inner wall of the mounting bracket 403. The level gauge 406 is an ultrasonic level gauge.

[0035] Under normal conditions, the filter plate 402 rests on one side of the drainage trough 404, and the sealing component 5 on that side of the drainage trough 404 is open, while the other side of the drainage trough 404 is closed by the sealing component 5. During filtration operations, wastewater flows in from the inlet trough on one side of the filter body 1, is distributed into the mounting frame 403, and is evenly distributed by the filter plate 402 on one side of the mounting frame 403, permeating into the filter media layer below. When the filter holes on the filter plate 402 become clogged, causing the liquid level in the mounting frame 403 to rise, the external controller detects this through the level gauge 406 and immediately activates the drive unit 405. The drive unit 405 drives the rotating shaft 401 to rotate at a certain angle, causing the filter plate 402 to rotate onto the other side of the drainage trough 404. Simultaneously, the sealing component 5 switches the opening and closing states of the two drainage troughs 404, keeping the drainage trough 404 on the side with the filter plate 402 open and the other side closed. At this time, sewage seeps outward from the other side of the filter plate 402, and the debris that had accumulated on the surface of the filter plate 402 falls onto the filter media layer below. At the same time, the blockages in the filter holes of the filter plate 402 are also flushed out in the reverse direction under the hydraulic pressure of the sewage. In practical applications, the filter plate 402 can also be set to rotate automatically at a set time through an external control system.

[0036] By using the rotating water distribution mechanism 4, the structure of the traditional V-shaped trough has been improved. The internal filter plate 402 can be reversed in time after the filter holes become clogged, and the blockage can be cleared by backwashing with water pressure. This ensures that the sewage can be evenly distributed on the lower filter media layer and avoids blockage in the V-shaped trough. This achieves long-term stable operation of the V-shaped filter and is more in line with the actual use requirements of the current V-shaped filter.

[0037] The sealing assembly 5 includes a sealing flap 501 and two sealing rods 502. The sealing flap 501 is symmetrically and movably installed on both sides of the mounting frame 403, and the upper end of the sealing flap 501 is rotatably connected to the upper groove of the drainage trough 404. The two sealing rods 502 are installed on the outside of the rotating shaft 401 to press the sealing flap 501 against the corresponding drainage trough 404. The arc-shaped part at the lower end of the mounting frame 403 slides in a staggered manner with the two sealing rods 502 through a sliding groove. If the sealing flap 501 cannot completely seal, the leakage of sewage into the lower filter layer will not affect the operation.

[0038] When the filter plate 402 is positioned on the left drainage trough 404, the right sealing rod 502 presses against the right sealing flap 501, sealing the right drainage trough 404 and allowing sewage to drain only from the filter plate 402. When the filter plate 402 rotates to the right and presses against the right drainage trough 404, the rotating shaft 401 drives both sealing rods 502 to rotate synchronously to the right, causing the left sealing flap 501 to be pressed against the left drainage trough 404 by the left sealing rod 502, sealing it and allowing sewage to drain only from the filter plate 402. In other words, regardless of which drainage trough 404 the filter plate 402 is positioned on, the other drainage trough 404 can be sealed by the sealing flap 501.

[0039] By using the sealing component 5, after the filter plate 402 is rotated and adjusted, the sealing flap 501 is used to simultaneously seal the drainage trough 404 on the other side. The entire process is linked through structural design, with good continuity, and the structure is simple and easy to maintain later.

[0040] The drive unit 405 includes a motor 4051 and a second bevel gear 4053. The motor 4051 is mounted on the side wall of the filter body 1, and a first bevel gear 4052 is mounted on the output end of the motor 4051. The second bevel gear 4053 is mounted on the end of the rotating shaft 401 located on the outside of the filter body 1 and meshes with the first bevel gear 4052.

[0041] When it is necessary to drive the rotating shaft 401 to rotate, the motor 4051 is started. The motor 4051 drives the rotating shaft 401 to rotate through the cooperation of the first bevel gear 4052 and the second bevel gear 4053.

[0042] A limiting strip 6 is installed on the outer side of the groove opening of the drainage channel 404 to limit the opening angle of the sealing flap 501. The limiting strip 6 can prevent the sealing flap 501 from opening too large, thereby causing the loss of control of the two sealing pressure rods 502.

[0043] The included angle of the drainage channels 404 on both sides of the mounting bracket 403 is 60-90 degrees, and the angle of the drainage channel 404 on one side is 30-45 degrees to ensure the water permeability.

[0044] The included angles between the two sealing pressure rods 502 and the filter plate 402 are equal to the included angles between the two drainage channels 404 on both sides, thus ensuring that when the filter plate 402 is in contact with the drainage channel 404 on one side, the drainage channel 404 on the other side can be closed by the sealing flap 501 under the action of the sealing pressure rods 502.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 preferred examples and are not intended to limit the utility model.
