Honeycomb filter element corrugated composite filter paper and novel sealing method for air outlet end of honeycomb filter element corrugated composite filter paper

Abstract

The invention discloses a novel sealing method for an air outlet end of honeycomb filter element corrugated composite filter paper comprises the following steps: dripping glue at the end point of the front section and / or the rear section of plane paper, pressing wave paper corresponding to the dripping glue, respectively applying pressing force along the front section and the rear section, and flattening the dripping glue under the action of external force so as to ensure effective sealing of a sealing port. The flattening direction is two-side type flattening, the stroke length of the dripping glue is shortened by half, the deformation accumulation degree of the wave paper during pressing and fixing is small, wrinkles are evenly distributed, and therefore the wind resistance capacity of the flattened end is greatly improved. According to the honeycomb filter element corrugated composite filter paper, pressure is applied to an uphill section and a downhill section respectively to form wrinkles on the honeycomb filter element corrugated composite filter paper, the deformation accumulation degree of the wave paper is small during pressing and fixing, the wrinkles are uniformly distributed, so that the wind resistance capacity of the flattened end is greatly improved, in other words, the breakage resistance degree is improved, and the risk of sealing leakage is reduced.

Description

technical field [0001] The invention relates to the technical field of air purification equipment, and more specifically relates to a novel sealing method for the air outlet end of a honeycomb filter element corrugated composite filter paper and a honeycomb filter element corrugated composite filter paper. Background technique [0002] The filter element is a device for air filtration and purification on an internal combustion engine. There are various types of filter elements, and the most widely used one is the honeycomb filter element. The honeycomb filter element is a filter element structure that has just emerged in the market. It has the advantages of small size, low resistance, large dust holding capacity, and easy removal of dust. [0003] The honeycomb filter element is made of corrugated paper. After the rolling is completed, one end of the filter element is the intake end, and the other end of the filter element is the closed end. The side of the corrugated paper...

Problems solved by technology

[0006] In general, corrugated paper mostly adopts U-shaped corrugated paper, that is, the wave paper b is pasted on the plane paper a, and the wave structure is a U-shaped wave structure. A large number of pleated structures c will be generated. If the treatment is not good, the corrugated paper b and the flat paper a may not be firmly pasted, and the pressure is not enough, and then there will be a problem of sealing failure, resulting in a decrease in the filtering effect and making the unfiltered unclean air directly into the engine, causing damage to the engine and seriously affecting the service life of the engine
