However, the filter will limit the air flow and affect the ventilation effect of the equipment. When the dust accumulates thickly, it will cause the gas to be unable to circulate, reducing the performance of the equipment. Utility Model Content

[0003] The utility model aims to provide a composite flat-plate filter to solve the problem that the filter proposed in the above background technology will limit the air flow and affect the ventilation effect of the equipment.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a composite flat-plate filter, comprising an outer frame and a filter element installed inside the outer frame;

[0005] A sealant is provided between the filter element and the outer frame to seal and fix the filter element;

[0006] A filter plate b is arranged on the left side of the filter element to filter impurities in the air, and a filter plate a is arranged on the left side of the filter plate b to filter impurities in the air. The left end outer walls of the filter plates a and b are both provided with a plurality of left-right through openings for air circulation.

[0007] Preferably, the inner walls at both ends of the upper and lower ends of the outer frame are fixedly connected with fixing blocks near the left side, and a fixing frame is arranged between the outer walls at the left ends of the two fixing blocks.

[0008] Preferably, a filter is fixedly connected inside the fixing frame to block sharp impurities, and a fixing screw that penetrates rightward into the fixing block is fixedly connected to the outer wall of the left end of the fixing frame to limit the position of the fixing frame.

[0009] Preferably, the filter plate a and the filter plate b are both inclined, and the openings opened on the filter plate a and the filter plate b are staggered with each other.

[0010] Preferably, the filter plate a and the filter plate b are both made of stainless steel, and the mesh density of the through opening is smaller than the mesh density of the filter screen.

[0011] Preferably, the inner walls at both ends of the outer frame are fixedly connected with protective nets, and a plurality of rubber lines are equidistantly arranged between the protective net and the filter element to limit the distance between the filter papers of the filter element to ensure smooth ventilation.

[0012] Compared with the prior art, the utility model provides a composite flat-plate filter, which has the following beneficial effects:

[0013] By installing the filter plates a, b and the openings, when the air circulates from left to right, the air will pass through the openings in the filter plates a and b, and finally be discharged after being filtered by the filter element. The inclined filter plates a and b can block the dust and particles in the air and then drop them onto the inner wall of the outer frame, thereby preventing the particles from adhering to the surfaces of the filter plates a and b and maintaining the air circulation rate. At the same time, the staggered design of the openings on the filter plates a and b can increase the surface area of ​​the air in contact with the filter plates a and b, thereby increasing the probability of dust and particles being blocked, thereby enhancing the filtering effect and ensuring that the pollutants in the air are effectively filtered. At the same time, the air circulation path is optimized, so that the air is more evenly distributed when passing through the filter plates a and b, thereby improving the filtering efficiency and preventing more dust and particles from accumulating on the surface of the filter element. At the same time, a filter screen is added to block sharp impurities in the air. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-3 A composite flat-plate filter is shown, comprising an outer frame 1 and a filter element 8 installed inside the outer frame 1;

[0020] A sealant 2 is provided between the filter element 8 and the outer frame 1 to limit the position of the filter element 8 and prevent leakage. The filter element 8 is cut into a size that fits the inner wall of the outer frame 1 in advance, and then placed into the outer frame 1. The sealant 2 is then injected into the position where the filter element 8 and the outer frame 1 fit together by a glue dispenser to fix and seal the filter element 8. When air is circulated, dust and particulate matter in the air are filtered through the filter element 8.

[0021] A filter plate b7 is arranged on the left side of the filter element 8 to filter impurities in the air, and a filter plate a6 is arranged on the left side of the filter plate b7 to filter impurities in the air. A plurality of through-holes 5 are provided on the left outer walls of the filter plates a6 and b7 for air circulation. When filtering the air, the air will first pass through the filter plates a6 and b7, intercept the dust and particulate matter in the air and let them fall on the inner wall of the outer frame 1. The unfiltered air passes through the through-holes 5 and then contacts the filter element 8 for final filtration.

[0022] like Figure 3 As shown, the inner walls of the upper and lower ends of the outer frame 1 are fixedly connected with fixed blocks 12 near the left side, a fixed frame 10 is arranged between the outer walls at the left ends of the two fixed blocks 12, a filter screen 11 is fixedly connected inside the fixed frame 10 to block sharp impurities, and the outer wall at the left end of the fixed frame 10 is fixedly connected with a fixing screw 9 that penetrates the inside of the fixed block 12 to the right to limit the position of the fixed frame 10.

[0023] Before the air enters the filter, sharp impurities in the air will be blocked by the filter screen 11 to prevent the sharp impurities from entering the inside of the filter and scratching the filter element 8. The fixed frame 10 can be removed by unscrewing the fixing screw 9 counterclockwise to clean the filter screen 11. After cleaning, the fixing frame 10 is abutted against the fixing block 12 and the fixing screw 9 is screwed in clockwise to limit the position of the fixing frame 10.

[0024] like Figure 1 and Figure 2 As shown, the filter plates a6 and b7 are both inclined, the openings 5 ​​opened on the filter plates a6 and b7 are staggered with each other, the filter plates a6 and b7 are both made of stainless steel, and the mesh density of the openings 5 ​​is smaller than the mesh density of the filter screen 11.

[0025] Dust and impurities are blocked by the inclined filter plates a6 and b7, and will move along the inclined slope or fall vertically to the inner wall of the outer frame 1. The staggered openings 5 ​​can prevent impurities from directly contacting the filter element 8 when air circulates, thereby increasing the filtering efficiency and service life.

[0026] like Figure 1 and Figure 2As shown, the inner walls at both ends of the outer frame 1 are fixedly connected with a protective net 4, and a plurality of rubber lines 3 are equidistantly arranged between the protective net 4 and the filter element 8 to limit the filter paper spacing of the filter element 8 to ensure smooth ventilation.

[0027] The protective net 4 and the filter element 8 are released from the outer frame 1, and when the dispensing machine injects the sealant 2, part of the sealant 2 is guided into the edges of the protective net 4 and the filter element 8, so that the filter element 8 is completely sealed without airflow short circuit and the protective net 4 is completely fixed.

[0028] The implementation principle of this embodiment is: the filter element 8 is cut into a size that fits the inner wall of the outer frame 1 in advance, and then placed in the outer frame 1. The sealant 2 is then injected into the position where the filter element 8 and the outer frame 1 fit together by a glue dispenser to fix the filter element 8. When the air is circulated, the dust and impurities in the air are filtered through the filter element 8. When the air is filtered, the air will first circulate through the filter screen 11 on the left side of the filter plate a6, and then pass through the filter plates a6 and b7 to intercept the dust and impurities in the air and fall on the inner wall of the outer frame 1. The unfiltered air passes through the opening 5 and then contacts the filter element 8 for final filtration.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
