Front-end filtering device of filter

Abstract

The invention discloses a front-end filtering device of a filter. The front-end filtering device of the filter comprises a filter air inlet and a filtering cover, wherein a plurality of first filtering holes which are distributed uniformly are formed in a side surface of the filtering cover; the bottom of the filtering cover is connected with the filter air inlet through a connecting ring; a filtering plate is arranged at the bottom of the filtering cover; a plurality of second filtering holes distributed uniformly are formed in the filtering plate; a rotating shaft is arranged in the middle of the filtering cover; a cleaning rod is arranged at the bottom of the rotating shaft; a cleaning wire brush is arranged on the cleaning rod; the upper end of the rotating shaft penetrates through thefiltering cover and is connected with a motor; dust suction tubes are arranged on two sides of the motor, and are connected with a small fan through an air inlet manifold; and an exhaust tube is arranged on the other side of the fan. The preliminary filtering device is arranged at the air inlet front end of the filter, filtering load of the filter is relieved, and therefore, the service life of the filter is greatly prolonged. The front-end filtering device of the filter is simple to design and operate, high in comprehensive practicability and easy to popularize and use.

Description

Technical field: [0001] The invention relates to a filtering device, in particular to a front-end filtering device of a filter. Background technique: [0002] A filter refers to an accessory that filters impurities or gases through filter paper. Generally refers to the car filter, which is an accessory of the engine. According to different filtering functions, it is divided into: oil filter, fuel filter (gasoline 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, generally called "three filters", plus an air conditioning filter, commonly known as four filters. They are respectively responsible for the lubrication system, the medium in the combustion system, the engine intake system, and the filtration of the cabin air circulation system. [0003] After the filter has been used for a period of time, due to too many impurities, the filter performance will decline...

AI Technical Summary

Problems solved by technology

[0003] After the filter has been used for a period of time, due to too many impurities, the filter performance will decline, which will affect the intake air quality of the engine, and make the engine gas and oil mix unevenly, resulting in increased fuel consumption. It needs to be replaced in time, which is very troublesome
