Description

Straight-flow type paper filter element single-stage air filter

Technical Field

The utility model relates to the technical field of air filters, in particular to a direct-current paper filter element single-stage air filter.

Background

The air filter is a short for air filter, is a main element of an air inlet filtering system of an internal combustion engine, and is used for filtering foreign matters such as dust in the air inlet and preventing faults such as early abrasion and the like caused by excessive impurities swallowed by the internal combustion engine. There are dry air filters (paper cartridge air filters) and wet air filters (oil bath air filters) commonly used. The paper filter element air filter comprises a direct-current air filter, the direct-current air filter has the advantage of low air inlet resistance, and meanwhile, the direct-current air filter is elliptical, so that the required installation space is smaller compared with the traditional circular air filter. These two advantages make the application of direct current air filter more and more extensive, especially be applicable to the application case that installation space is compact.

The prior patent CN201922268691.4 discloses a direct-current air filter with a combined filter core, and the air filter adopts two circular safety filter cores and two circular main filter cores which are arranged in parallel in a general arrangement in a shell, so that the requirement of large air inlet flow can be met; the safety filter element and the main filter element are arranged in series and can be sequentially taken out from the rear end of the shell; the end cover type prefilter adopts a circular structure and is installed in a buckled mode, the dust exhaust port can be guaranteed to be vertical downwards all the time by adjusting the angle at will during installation, the dust exhaust effect is guaranteed, the performance requirements of different installation angles are met, and the installation space is effectively utilized.

However, the air filter still has the disadvantage that the paper filter element inside the air filter is saturated due to dust collection after the air filter works for a period of time, so that the air flow is slow, the air filtering effect is poor, and the use is affected, therefore, the filter element needs to be replaced periodically, a pipeline connected with the right end of the air filter needs to be disconnected when the air filter is replaced, then the filter element can be taken out from the side, the disassembly and the assembly are more troublesome, and the filter element is likely to be disassembled from the side, so that the operation space is insufficient due to the reason of the installation position, the operation is difficult, and the improvement is needed.
