Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a high-efficiency filter element structure used for filters. Background Art

[0002] A filter is a device used to filter solid particles, liquids or gases. Its main function is to separate impurities, pollutants or solid particles from the fluid to improve the purity and quality of the fluid. Filters are widely used in various fields, including industrial production, water treatment, air purification, automobiles, medical equipment, etc.

[0003] In the existing filter elements, single-layer filter elements are generally used for filtration. Since the single-layer filter element has only one layer of filter material to filter particles and impurities in the fluid, the filter element cannot effectively capture and block smaller particles, resulting in low filtration efficiency. At the same time, due to the limited filtration capacity of the single-layer filter element, when particles and impurities accumulate on the surface of the filter element, the pressure difference will increase rapidly. The increased pressure difference will affect the speed at which the fluid passes through the filter element, thereby increasing energy consumption and affecting the normal operation of the filter. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a high-efficiency filter element structure for a filter.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-efficiency filter element structure for a filter, comprising a filter body, wherein a built-in groove is provided inside the filter body, a pre-filtering layer plate is arranged in the built-in groove, and the pre-filtering layer plate is a pleated structure;

[0007] A first filter core is arranged below the pre-filter layer plate, a second filter core is arranged at the bottom of the first filter core, a third filter core is arranged at the bottom of the second filter core, the second filter core is connected and fixed to the first filter core and the third filter core through a supporting column, and the first filter core, the second filter core and the third filter core are stacked in sequence to form a stepped structure.

[0008] A pipe groove is provided on the inner wall of the filter body, a connecting water pipe is arranged in the pipe groove, a plurality of spray heads are arranged on the outside of the connecting water pipe, the spray heads are connected to the connecting water pipe, one end of the connecting water pipe passes through the pipe groove and extends to the outside of the filter body and is connected to a water tank, and a water pump is arranged at one end of the connecting water pipe close to the water tank.

[0009] A support plate is fixedly connected to one side of the inner wall of the built-in groove, an electric push rod is arranged in the middle of the outer wall of the support plate, the output end of the electric push rod is connected to a driving rod, and a cleaning scraper is fixedly connected to one end of the driving rod away from the electric push rod, and the cleaning scraper is in contact with the surface of the first filter element.

[0010] The first filter core, the second filter core and the third filter core are all provided with a plurality of filter holes, and the apertures of the filter holes decrease from top to bottom.

[0011] The two sides of the pre-filtering layer plate are fixedly connected with connecting plates, and the pre-filtering layer plate is connected and fixed with the built-in groove through the connecting plates.

[0012] The beneficial effects of the utility model are:

[0013] The pleated structure of the pre-filter layer is used to perform preliminary filtration on the original fluid. Compared with ordinary flat filter elements, it effectively increases its surface area and can provide more filtration area for capturing particles and impurities. At the same time, since the pleated structure has more folding points and gaps, particles can be more easily retained on its surface during filtration, and will not directly penetrate or pass through the gaps, thereby improving the particle interception ability. By adopting a stepped gradient filtration structure, particles and impurities of different sizes can be gradually filtered out during filtration. At the same time, the fluid pressure can be evenly distributed, reducing the resistance of the fluid passing through the filter element, thereby reducing the pressure difference and energy consumption, maintaining the stability of the filtration efficiency, making the filter element structure more solid and not easy to deform or break, and further improving the service life of the filter.

[0014] By flushing the surface of the first filter element, the electric push rod drives the driving rod and the cleaning scraper to move along the surface of the first filter element. When the cleaning scraper moves on the surface of the first filter element, the particulate impurities remaining on the first filter element can be scraped and cleaned, thereby completing the cleaning of the surface of the first filter element, preventing the particulate impurities from adhering to the first filter element and clogging the first filter element, so that the filter maintains a state of high-efficiency filtration.

[0024] Embodiment 1:

[0025] Reference Figure 1-4 A high-efficiency filter element structure for a filter comprises a filter body 1, a built-in groove is provided inside the filter body 1, a pre-filtering layer plate 3 is arranged in the built-in groove, and the pre-filtering layer plate 3 is a pleated structure;

[0026] A first filter element 4 is arranged below the pre-filter layer plate 3, a second filter element 5 is arranged at the bottom of the first filter element 4, a third filter element 6 is arranged at the bottom of the second filter element 5, the second filter element 5 is connected and fixed to the first filter element 4 and the third filter element 6 through a support column 7, the first filter element 4, the second filter element 5 and the third filter element 6 are stacked in sequence to form a stepped structure.

[0027] A plurality of filter holes are formed on the first filter core 4 , the second filter core 5 and the third filter core 6 , and the diameters of the filter holes decrease from top to bottom.

[0028] The two sides of the pre-filtering layer plate 3 are fixedly connected with connecting plates 2 , and the pre-filtering layer plate 3 is connected and fixed to the built-in groove through the connecting plates 2 .

[0029] In this embodiment, when the filter body 1 is used for filtering, first, when the fluid flows through the pre-filter layer plate 3, the pre-filter layer plate 3 performs preliminary filtering on the original fluid, thereby reducing the load on the first filter element 4, the second filter element 5 and the third filter element 6 in the subsequent filtering process. The pre-filter layer plate 3 adopts a pleated structure. Compared with an ordinary flat filter element, the pleated pre-filter layer plate 3 effectively increases its surface area, and can provide more filtering area for capturing particles and impurities. At the same time, because the pleated structure has more folding points and gaps, the particles are more easily trapped on the surface of the pre-filter layer plate 3 when passing through the pre-filter layer plate 3, and will not directly penetrate or pass through the gaps, thereby improving the interception ability of the particles. Compared with a flat filter element, the pleated pre-filter layer plate 3 is less likely to be blocked, and can maintain high-efficiency filtration for a longer period of time, thereby improving the operating efficiency of the filter body 1;

[0030] After the pre-filter layer plate 3 performs preliminary filtration on the fluid, the fluid then passes through the first filter element 4, the second filter element 5 and the third filter element 6 in sequence. Since the first filter element 4, the second filter element 5 and the third filter element 6 form a stepped gradient filtration structure from top to bottom, each layer of the filter element provides an additional filtration surface, and the aperture of the filtration holes decreases from top to bottom, so that the fluid can gradually filter out particles and impurities of different sizes when passing through the first filter element 4, the second filter element 5 and the third filter element 6. At the same time, the stepped design of the three-layer filter element can distribute the fluid pressure more evenly, reduce the resistance of the fluid when passing through the filter element, thereby reducing the pressure difference and energy consumption, maintaining the stability of the filtration efficiency, making the filter element structure more solid and not easy to deform or break, and further extending the service life of the filter element.

[0034] In the present embodiment, when the filtering is completed, the water pump is started, and then the water in the water tank flows through the connecting water pipe 9 and is sprayed out through the sprinkler head 10, so that the surface of the first filter element 4 can be rinsed, and then the electric push rod 12 is started. When the electric push rod 12 is running, it drives the driving rod 13 to move, and when the driving rod 13 moves, it drives the cleaning scraper 14 to move along the surface of the first filter element 4. When the cleaning scraper 14 moves on the surface of the first filter element 4, it can scrape and clean the particulate impurities remaining on the first filter element 4, completing the cleaning of the surface of the first filter element 4, preventing the particulate impurities from adhering to the first filter element 4 and clogging the first filter element 4, so that it maintains a state of high-efficiency filtration.
