Problems solved by technology

In the prior art, the air filter is composed of a filter element and a housing. During use, the filter element of the air filter is easy to accumulate dust, resulting in poor air intake of these devices and affecting normal work.
Therefore, the existing air filter needs regular maintenance. During maintenance, it is generally necessary to remove the filter element to clean the dust on it or replace it with a new filter element. This not only brings heavy labor to the maintenance personnel, but also affects the normal operation of the equipment. At the same time, the air intake of the existing air filter is relatively fixed, and when the engine is running at high speed, insufficient air intake often occurs
[0003] In addition, the adsorption capacity of the filter element in the existing filter is relatively weak, and the replacement cycle is relatively short

Abstract

The invention relates to the technical field of auto spare parts, in particular to a method for processing a filter element component of an air filter. The method comprises the steps: preparing a filter paper layer by a conventional process, and preparing a frame by forging carbon steel; putting the filter paper layer in a preprocessing solution for soaking for more than 12 hours, draining off after taking out the filter paper layer, and then drying the filter paper layer at 55 DEG C, wherein the preprocessing solution is prepared by putting 20 parts of water-based epoxy resin emulsion, 10 parts of thixotropic agent, 10 parts of water-soluble silicates, 5 parts of carbon back, 3 parts of glycerol, 6 parts of cypermethrin and 6 parts of geraniol in a reaction still for reacting for 2 hours at 75 DEG C; inserting the edge of the filter paper layer into the frame, press-fitting the inner edge of the frame, then mounting the frame loading the filter paper layer in a shell, and finally mounting a vibrator at the outer part of the shell. During processing, the filter paper layer is preprocessed, therefore the adsorption capacity of the filter paper layer is enhanced, and the replacement cycle is long.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a processing method for a filter element assembly of an air filter. Background technique [0002] The air filter is a commonly used auto accessory, which is mainly used to provide clean air for the engine to prevent these engines from inhaling air with impurity particles during operation and increasing the chance of abrasion and damage. In the prior art, the air filter is composed of a filter element and a housing. During use, the filter element of the air filter is very easy to accumulate dust, resulting in poor air intake of these devices and affecting normal operation. Therefore, the existing air filter needs regular maintenance. During maintenance, it is generally necessary to remove the filter element to clean the dust on it or replace it with a new filter element. This not only brings heavy labor to the maintenance personnel, but also affects the normal operation of the ...
