Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, in the prior art, the filter relies on a single filter ring to intercept and filter out harmful impurities in the fluid. The smaller the filter holes on the surface of the filter ring, the better the filtering effect, but the fluid passing capacity is limited. The worse it is, in order to solve the problem of filtering out the smallest particles of impurities on the same filter ring, and enabling the fluid to pass through the filter holes on the ...

Embodiment approach

[0031] As an embodiment of the present invention, a guide plate 21 is fixedly connected between the fixed plate 1 and the outer arc surface of the guide joint 3; the number of the guide plates 21 is four, and the axis of the fixed plate 1 is the center Evenly arranged; the guide plate 21 slides up and down with respect to one side of the filter ring 2 and is connected with the same moving ring 22; the inner arc surface of the moving ring 22 is fixedly connected with a cleaning brush 23; After long-term use, a large amount of impurities will adhere to the surface of the filter ring 2, which will have a serious impact on the filtration value of the filter. Therefore, by setting the moving ring 22, the moving ring 22 moves up and down on the surface of the guide plate 21, and then drives its inner The cleaning brush 23 on the curved surface moves up and down, so the cleaning brush 23 can quickly clean the outer curved surface of the filter ring 2, which solves the problem of a lar...

Abstract

The invention belongs to the technical field of filter filtration, and particularly relates to a filter outer net and a preparation method thereof. The filter outer net comprises a fixed plate, a filter ring and a diversion joint; the filter ring is arranged between the fixed plate and the diversion joint; the inner arc surface of the filter ring is connected with an adjusting ring in a vertical sliding manner; filtering holes, which are uniformly distributed, are formed in the surface of the filter ring; adjusting holes, which are uniformly distributed, are formed in the surface of the adjusting ring, and the adjusting holes are matched with the filtering holes. The automatic adjustment of the filter value of the filter is effectively realized, the requirements of different fluids and different fluid states on various filter values can be met, and when the filter is used for a long time and the filter holes are blocked, the sizes of the filter holes can be automatically adjusted according to the pressure difference change, so that the problem of insufficient downstream fluids is solved.

Description

technical field [0001] The invention belongs to the technical field of filter filtration, in particular to a filter outer net and a preparation method thereof. Background technique [0002] A filter refers to an accessory that filters impurities or gases through filter paper. It generally refers to an automotive filter, which is an engine accessory. According to different filtering functions, it is divided into: oil filter, fuel filter (gasoline filter) filter, diesel filter, oil-water separator, hydraulic filter), air filter, air conditioning filter, etc. The engine has three types of filters: air, oil, and fuel, which are generally called "three filters". The upper cabin filter, commonly known as the four filters, is responsible for the filtration of the lubrication system, the medium in the combustion system, the engine intake system, and the cabin air circulation system. [0003] According to CN106731101A, a filter outer net and its preparation method, in the prior art,...
