Problems solved by technology

[0002] The engineering vehicle is connected with an air intake pre-filter device outside the air filter (such as an external air intake, intake pipe, etc.), there may be no pre-filtering effect, or the pre-filtering effect is not obvious, such as Dongfeng, which is widely used in the market now. In addition to ensuring large air intake flow and high air intake position to avoid dust accumulation on the ground, the air intake inlet pipe device of Tianjin Jin and Tianlong cars does not have a coarse filter effect, and there is room for improvement

Embodiment Construction

[0008] Such as figure 1 As shown, the present invention is further described as follows: the rotary air intake pre-filter device includes an air intake pipe, and the air intake pipe is integrally connected by a horizontal air intake pipe 1, a vertical air intake pipe 2, and an installation end 3 of the air filter; figure 1 The arrows in (two straight arrows, multiple arc-shaped arrows) express the flow direction of the air, and a plurality of baffles 4 are interlaced with each other in a certain interval along the vertical direction in the vertical air intake pipe, so that in the vertical In the intake pipe 2, a rotary air intake channel is formed (such as figure 1 Shown by the arc-shaped arrow in); the outer wall of the vertical intake pipe is provided with a dust collecting pan 5, and the dust collecting pan 5 communicates with the bottom of the baffle plate 4 in the vertical air intake duct (the large dust particles are under inertial centrifugal force and gravity Under th...

Abstract

The invention provides a circling type inlet air pre-filtering device. The circling type inlet air pre-filtering device comprises an air inlet pipe. The air inlet pipe is formed by integrally connecting a transverse air inlet pipe body, a vertical air inlet pipe body and the installation end of an air filter. A plurality of baffles are arranged in the vertical air inlet pipe body at certain intervals in a mutually staggered manner in the vertical direction, so that a circling type air inlet channel is formed in the vertical air inlet pipe. A dust collecting disk is arranged on the outer wall of the vertical air inlet pipe body, and the dust collecting disk communicates with the bottoms of the baffles in the vertical air inlet pipe bodies. According to the circling type inlet air pre-filtering device, the circling type air inlet and dust removing idea is introduced to an external air inlet pipe path of the air filter, the pre-filtering effect is enhanced, the filtering load of the air filter is reduced, the maintenance period of a filter element of the air filter is prolonged, the filter element maintenance labor intensity of a driver is lowered, and the circling type inlet air pre-filtering device has relatively good economic applicability.

Description

technical field [0001] The invention belongs to an air intake pre-filter device externally connected to an air filter, in particular to a rotary air intake pre-filter device. Background technique [0002] The engineering vehicle is connected with an air intake pre-filter device outside the air filter (such as an external air intake, intake pipe, etc.), there may be no pre-filtering effect, or the pre-filtering effect is not obvious, such as Dongfeng, which is widely used in the market now. In addition to ensuring a large air intake flow and high air intake position to avoid dust accumulation on the ground, the intake pipe device of Tianjin Jin and Tianlong cars does not have a coarse filtration effect, and there is room for improvement. Contents of the invention [0003] In order to make the intake pre-filter device have a pre-filter effect, reduce the filter load of the air filter, and prolong the maintenance cycle of the filter element, the invention proposes a rotary in...
