Description

A filter grid with a cleaning structure Technical Field

[0001] This utility model relates to the field of filter grid technology, specifically a filter grid with a cleaning structure. Background Technology

[0002] A filter bar is a device used to intercept and separate floating, suspended, and solid impurities from fluids (such as sewage, industrial wastewater, river and lake water, etc.). Through a filtration structure composed of bars or screens, impurities are trapped on the surface of the bar, preventing them from entering subsequent treatment systems or processes. This ensures the normal operation of pumps, pipelines, valves, and other equipment, and avoids equipment failure caused by blockage and wear due to impurities. It is an indispensable pretreatment device in water treatment, industrial production, and many other fields. In sewage treatment, water supply and drainage engineering, industrial fluid filtration, and many other areas, filter bars play an irreplaceable role as a key component for intercepting impurities and ensuring the normal operation of subsequent equipment.

[0003] Traditional filter screens mostly rely on manual cleaning periodically. Operators wearing protective gear and using tools such as rakes and hooks to manually remove garbage and impurities adhering to the screens. This method is not only labor-intensive but also inefficient. Furthermore, while some traditional filter screens are equipped with simple mechanical cleaning devices, such as chain scrapers, they have significant drawbacks. The chains are prone to rusting and breaking after prolonged immersion in sewage, resulting in a short average lifespan. The scraper blades also have poor adhesion to the screen surface, making them ineffective at cleaning impurities in tiny gaps and pores, thus failing to meet the requirements of fine filtration. Therefore, it is necessary to design a filter screen with a cleaning structure. Summary of the Invention

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1:

[0024] Based on the existing problems of easy clogging of filter grids and low efficiency of manual cleaning, the present invention provides a preferred embodiment of a filter grid with a cleaning structure, as shown in Figures 1-4: A filter grid with a cleaning structure includes a filter grid mounting frame 1, a filter grid plate 2 fixedly installed on the inner wall of the filter grid mounting frame 1, and filter holes evenly spaced on the outer wall of the filter grid plate 2. Micro-slip grooves 3 are evenly spaced on the front side of the filter grid plate 2, and a fixing frame 4 is evenly spaced on the back side of the filter grid plate 2. A cleaning component 5 is disposed on the front and back sides of the filter grid plate 2. The cleaning component 5 includes: a scraping part 51 disposed on the front side of the filter grid plate 2; and a cleaning part 52 disposed on the back side of the filter grid plate 2, and the cleaning part 52 is disposed behind the scraping part 51.

[0025] The scraping part 51 includes: a connecting top plate 511, which is fixedly installed on the front of the filter grid mounting frame 1; a first movable sliding hole 512 is provided on the top of the connecting top plate 511; a protective shell 513 is provided below the connecting top plate 511 and is fixedly installed on the front of the filter grid mounting frame 1; a second movable sliding hole 514 is provided on the top of the protective shell 513 and is compatible with the first movable sliding hole 512.

[0026] A small motor 515 is fixedly installed on the inner wall of the protective shell 513. The output end of the small motor 515 is provided with an adjusting screw 516 through a coupling. A movable block 517 is slidably connected to the outer wall of the adjusting screw 516. A T-shaped movable block 518 is slidably connected inside the movable sliding hole 512.

[0027] A cleaning scraper 519 is fixedly installed on the top of the movable block 517 and the bottom of the T-shaped movable block 518 by a fixing rod, and the cleaning scraper 519 extends to the front of the filter grid plate 2.

[0028] Furthermore, in this embodiment, a cleaning scraper 519 is provided. Driven by a small motor 515 and an adjusting screw 516, the scraper slides inside the first sliding hole 512 and the second sliding hole 514, thereby driving the cleaning scraper 519 to scrape off impurities covering the front of the filter grid plate 2. Compared with traditional manual cleaning, the efficiency of removing large impurities is improved.

[0029] Example 2:

[0030] Please refer to Figures 1-4, and based on Embodiment 1, further: the cleaning part 52 includes: a mounting slot 521, which is opened on the back of the filter grid mounting frame 1; a connecting strip 526, which is fixedly installed on the back of the filter grid mounting frame 1 and is positioned above the mounting slot 521; a limiting plate 522 is fixedly installed on the inner wall of the mounting slot 521; a cleaning liquid bottle 523 is installed inside the mounting slot 521 by snap-fit, and the limiting plate 522 is used to protect the cleaning liquid bottle 523; a display panel 524 is fixedly installed on the front of the cleaning liquid bottle 523.

[0031] The cleaning liquid bottle 523 is equipped with a liquid delivery pipe 525 through a small water pump, and the liquid delivery pipe 525 extends into the interior of the filter grid mounting frame 1. A trapezoidal inclined shell 527 is fixedly installed at the bottom of the connecting frame 526, and an installation groove is opened inside the trapezoidal inclined shell 527. An angled hole 528 is opened on the inner side of the trapezoidal inclined shell 527.

[0032] A connecting pipe 529 is fixedly installed inside the mounting slot. The other end of the liquid delivery pipe 525 movably passes through the outer wall of the trapezoidal inclined shell 527 and extends into the interior of the connecting pipe 529. Spraying pipe heads 5210 are evenly and uniformly connected to the outer wall of the connecting pipe 529. The spraying pipe heads 5210 pass through the angled holes 528 and extend to the back and top of the filter grid plate 2.

[0033] Below the spray nozzle 5210, there is a wastewater collection tank 5211, and the wastewater collection tank 5211 is located at the bottom of the inner wall of the filter grid mounting frame 1. There are two sets, located in front of and behind the filter grid plate 2 respectively.

[0034] Furthermore, this embodiment features a spray nozzle 5210 paired with a small water pump, which uses high-pressure spray cleaning fluid to penetrate deep into the filter holes, facilitating the removal of fine impurities and solving the problem of easy clogging of traditional filter grids. This effectively maintains filtration efficiency. The cleaning fluid bottle 523 is designed with a snap-fit ​​mechanism, making it easy to replace. Additionally, the wastewater collection tank 5211 is equipped with two tanks to collect wastewater from scraping and cleaning, respectively, facilitating centralized treatment and reducing the risk of secondary pollution.

[0035] During use, as fluid passes through the filter holes of the filter grid plate 2, impurities gradually accumulate over time, adhering to the filter holes and the surface of the grid plate, leading to a decrease in filtration efficiency. At this point, the operator activates the cleaning component 5 via an external control switch to restore filtration performance.

[0036] First, the scraping action is initiated by the scraping section 51, which starts the small motor 515 and drives the adjusting screw 516 to rotate. Due to the sliding connection between the adjusting screw 516 and the moving block 517, the moving block 517 moves axially under the rotation of the screw. The moving block 517 drives the T-shaped moving block 518 via a fixed rod, causing it to slide within the first and second sliding holes 512 and 514, thereby causing the cleaning scraper 519 to reciprocate linearly on the front of the filter grid plate 2. The cleaning scraper 519 adheres closely to the surface of the filter grid plate 2, scraping away large pieces of impurities attached to the front. The scraped impurities fall into the wastewater collection tank 5211 in front.

[0037] Furthermore, the cleaning unit 52 operates simultaneously, with the small water pump inside the cleaning liquid bottle 523 starting up to deliver the cleaning liquid to the connecting pipe 529 via the delivery pipe 525. The cleaning liquid is then distributed to each spray nozzle 5210 via the connecting pipe 529 and sprayed at a certain angle onto the back of the filter grid plate 2 through the angled holes 528. The high-pressure cleaning liquid not only flushes away impurities on the back but also flows backward through the filter holes, thoroughly removing the fine impurities clogging the holes. The flushed-down impurities flow with the cleaning liquid into the wastewater collection tank 5211 at the rear.

[0038] Throughout the cleaning process, the micro-slip grooves 3 facilitate the flow of cleaning fluid on the surface of the filter grid plate 2, improving the cleaning effect. The fixing frame 4 enhances the structural strength of the filter grid plate 2, preventing it from deforming under the impact of high-pressure cleaning fluid. The display panel 524 displays the remaining cleaning fluid in the cleaning fluid bottle 523 in real time, facilitating timely replenishment. The limiting plate 522 ensures the stability of the cleaning fluid bottle 523 in the locked state, preventing it from falling off or shaking.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
