Telescopic filter element, and filter with replaceable filter element

Abstract

The invention discloses a telescopic filter element, and a filter with a replaceable filter element. The telescopic filter element comprises a wave-shaped filter part, first edge sealing strips and second edge sealing strips are arranged on the periphery of the wave-shaped filter part, the first edge sealing strips are arranged on the two sides of the folded edge of the filter part, the second edge sealing strips are arranged on the two sides of the multi-folded edge of the filter part, and fixing pieces are further arranged on the two sides of the multi-folded edge; and the filter with the replaceable filter element comprises the filter element and a frame, the frame is formed by splicing a first frame piece and a second frame piece, the whole frame piece is of an L-shaped structure, the upper edge of the top end of the long side of the frame piece is arranged to be an inclined face, an inclined protruding strip, a hollow reinforcing rib and a protective net baffle are sequentially arranged on the inner side of the long side from top to bottom, a surface protecting net is installed between the protective net baffle and the L-shaped short edge, and the filter element is installed in the upper space of the surface protecting net. The frame body and the filter element can be separated, the frame can be reused, the filter element can be replaced regularly, and energy conservation and consumption reduction are achieved; and the filter element is telescopic and is convenient to transport and store after being compressed.

Description

technical field [0001] The invention relates to a retractable filter core and a replaceable filter core filter, belonging to the technical field of air purification. Background technique [0002] The acceleration of urbanization has led to increasingly serious air pollution. Most cities are suffering from smog, especially in industrially developed cities. The air quality is worrying, and the number of patients suffering from respiratory diseases is on the rise. In order to protect their own health, people pay more and more attention to their surrounding environment. [0003] For example, in semiconductor, liquid crystal panel, photovoltaic industry, air-conditioning box and other operating environments, there are many odors and gaseous pollutants that need to be treated, such as controlled SO 2 , HF, HCl, acid gases and NH 3 , amines, alkaline gases, etc. Chemical gaseous filters for AMC removal stand out for their low initial pressure drop and stable pressure drop change...

AI Technical Summary

Problems solved by technology

[0007] (1) The multi-layer stacking method of the filter is not stable, and usually requires buckles and other forms to fix the layers

[0008] (2) The frame and the filter element are often connected by glue injection. The production process produces pungent odor gas, which endangers the health of the operator. The glue injection and solidification process is time-consuming, and the excess glue is labor-intensive, and the filter contains a large amount of polluting chemicals.

[0009] (3) The frame connected by riveting and welding has defects such as cumbersome blanking and error-prone, long assembly time, and air pollution

[0010] (4) The application environment with limited installation space puts forward strict requirements for filter installation and replacement, and if the filter size and maintenance activity space are too large, it cannot be applied

[0011] (5) Affected by the cleanliness of the application environment, it is difficult to wear high-strength labor protection products during the installation and replacement of the filter, and the corners of the filter are easy to cause scratches, falling and smashing

Even if the filter element can be packaged separately, the transportation space is too large, and there is no professional fixed pleat distance equipment on the application site, the filter element will fail if it is accidentally squeezed and damaged

[0013] (7) When multi-layer filters are stacked and used, because the folded peaks are difficult to stabilize on a vertical plane, the airflow is easily disturbed, resulting in high pressure loss and reduced efficiency

[0014] (8) Under the application conditions of large air volume, the supporting effect of common card combs and filter elements covering the net is weak, and the filter element may collapse when the filter element is deformed, and the filter is damaged and fails.
