Centrifugal self-cleaning air filter device and working method thereof

Abstract

The invention provides a centrifugal self-cleaning air filter device and a working method thereof. A motor drives a brush to sweep the surface of a dust screen, and therefore it is guaranteed that anair inlet is unblocked; a driving motor in an air filter works, the driving motor drives a filter round cage inner net and a filter round cage outer net to rotate by being connected with an inner gearof the air filter, a high-pressure air gun inserted into the filter round cage inner net sprays high-pressure air, and dust is removed through centrifugal force and high-pressure air flow; and meanwhile, a dust suction machine connected to a dust suction port starts working to collect dust in the air filter, a self-cleaning function is completed, and therefore not only can an ideal filtering effect be achieved in a bad air environment, but also daily maintenance is convenient.

Description

technical field [0001] The invention relates to the field of engine air filters, in particular to a centrifugal self-cleaning air filter device with self-cleaning function and a working method thereof. Background technique [0002] The air filter is an important part near the car engine. When the internal combustion engine of a car is working, fuel combustion requires a large amount of air, and a large amount of air enters the cylinder. If the air is not filtered, impurities or dust in the air will be sucked into the cylinder, which will accelerate the wear of the spark plug group and cylinder, and shorten the service life of the engine. Practice has proved that if the engine is not equipped with an air filter, its life will be shortened by 2 / 3. If the large impurity particles in the air enter between the piston and the cylinder, it will affect the lubrication, and more seriously, it will cause serious cylinder scuffing. The filter is installed in front of the carburetor o...

AI Technical Summary

Problems solved by technology

Due to the influence of the open-air environment, the cleaned dust is easily blown into the inner hole of the filter element again, causing secondary pollution to the air filter element and affecting the service life of the engine

At the same time, the cleared dust has caused serious pollution to the environment, especially to the health of operators.

Although this will remove the floating dust on the surface, the internal large particles of dust are difficult to remove from the air filter due to their own gravity, which will make the dust removal incomplete and affect the filtering effect of the air filter.

[0005] In view of the above situations and problems, it is particularly important to design a brand new air filter to solve the problem of inconvenient maintenance of the air filter under severe working conditions.
