Special vehicle air cleaner

Abstract

The invention provides a special vehicle air cleaner. The air cleaner comprises an air cleaner housing, and an air outlet pipe and a dust outlet of a first-stage filter of the air cleaner are respectively connected with an air inlet of the air cleaner housing and an inlet of a dust exhaust housing. The air cleaner housing is internally provided with an air inflow separating plate which is verticalto an air outlet direction of the air outlet and includes a hole. The hole is provided with a second-stage filter on an air flow direction. The second-stage filter is a V-type filter. Through cooperation of the first-stage filter and the second-stage filter, the technical scheme can effectively remove impurity particles in air, and provides air whose purity is approach to 100% for an engine, andprevents abrasion and damages on internal components of the engine to the maximum extent. Even though in environment that dust content is high, long-time continuous operation of a vehicle can be guaranteed. The special vehicle air cleaner realizes characteristics of high air intake flow and slow resistance variation. The special vehicle air cleaner improves sealing property of filter element installation, and is simple and reliable in structure, and can be conveniently maintained and repaired.

Description

technical field [0001] The invention relates to an air filter, in particular to a special vehicle air filter. Background technique [0002] Air filters are mainly used in pneumatic machinery, internal combustion machinery and other fields. The function is to provide clean air for these mechanical equipment, so as to prevent these mechanical equipment from inhaling air with impurity particles during work and increasing the chance of abrasion and damage. Air The working requirement of the filter is to be able to undertake high-efficiency air filtration, not to add too much resistance to the air flow, and to be able to work continuously for a long time. [0003] However, the application environment of the air filter is complex. With the different application environments, the requirements for its performance and characteristics are also different. The working environment of special vehicles is generally more complicated. It is not a common urban environment. Most of them are d...

Problems solved by technology

[0003] However, the application environment of the air filter is complex. With the different application environments, the requirements for its performance and characteristics are also different.

The working environment of special vehicles is generally more complicated. It is not a common urban environment. Most of them are deserts, industrial and mining areas, and plateau areas. This puts forward higher requirements for the performance of the air filter of special vehicles than ordinary vehicles. On the premise of ensuring that the performance indicators meet the requirements of the working conditions of special vehicles, it can ensure that the installation and sealing structure of special vehicles can work reliably under complex working conditions, and at the same time ensure that the structure is simple, reliable, and easy to maintain. However, the current air filter of special vehicles device does not meet these requirements very well
