Intake port dust removing device for gas brake heavy truck

Abstract

The invention provides an intake port dust removing device for a gas brake heavy truck. The device comprises a gas collecting body; a gas collecting bag is arranged in the gas collecting body; a cavity is formed between the surface of the gas collecting bag and the inner wall of the gas collecting body; an intake port is formed in the surface of the gas collecting body; an intake pipe is welded onthe inner wall of the intake port; one end of the intake pipe penetrates through and extends into the gas collecting bag, and the other end of the intake pipe is positioned on the outer surface of the gas collecting body; a one-way gas guide valve is fixedly mounted on the inner wall of the intake pipe; a gas spraying pipe sleeves the end, positioned on the outer surface of the gas collecting body, of the intake pipe; and the device relates to the field of trucks. The intake port dust removing device for the gas brake heavy truck recovers gas emptied by gas brake, and waste gas is used for spraying to an engine intake system, so that the influence on an engine by gravels and dust is reduced, the energy-conservation and environmental-protection effect is excellent, and the problem of increment of the maintenance cost due to adverse effect on the engine intake system by flying dust in the driving process of general heavy trucks is effectively solved.

Description

technical field [0001] The invention relates to the technical field of trucks, in particular to an air intake dust removal device for heavy trucks with air brakes. Background technique [0002] At present, many heavy trucks use the air brake system to brake. When braking, in order to balance the air pressure, the gas will be discharged from the exhaust port. It is also large, and a large amount of dust is often raised when driving. The dust will float from the bottom of the truck under the action of inertia at the bottom of the car. If this happens for a long time, a large amount of dust will affect the intake system of the truck engine, and it needs to be cleaned frequently. Carry out maintenance on this place, more frequent maintenance will make the maintenance cost of heavy trucks higher, and the dust raised by general heavy trucks during driving will have an adverse effect on the engine air intake system, increasing maintenance costs, So need a kind of air brake heavy-d...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an air intake dust removal device for heavy-duty trucks with air brakes, which solves the problem that the dust raised by general heavy-duty trucks during driving will adversely affect the engine intake system , the problem of increasing maintenance costs
