Sand-wind-proof mechanical filter for rail vehicle

Abstract

The invention discloses a sand-wind-proof mechanical filter for a rail vehicle. The filter comprises a shell with an opening, wherein a first filter screen is arranged on the front part of an inner chamber of the shell, a sand wind filtering device is arranged in the middle of the inner chamber of the shell, a wind hole is formed in the side surface, away from the opening, of the shell, and the wind hole is fixedly connected with an air inlet of a wind gathering pipe; the sand wind filtering device comprises a first air induction plate, a first wind shield, a second air induction plate, a second wind shield, a rear filter screen and a housing with the two ends open, the first air induction plate with the outer end higher and the inner end lower is fixed to the side, close to the first filter screen, of the interior of the housing, and the first wind shield is fixed to the position of an air outlet of the first air induction plate. According to the sand-wind-proof mechanical filter forthe rail vehicle, because multiple filter screens are used for filtration, the complete filtration effect is achieved, high-speed wind is induced into the sand wind filtering device by an air induction pipe, the filtration efficiency is improved, and it is avoided that secondary pollution is caused when the sand wind filtering device is saturated.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a wind-sand-proof mechanical filter for rail vehicles. Background technique [0002] my country has a vast territory, complex terrain, and changeable weather. When rail vehicles are running outside, they will inevitably encounter various wind, sand, rain and snow. Therefore, air filtration devices must be installed at the front inlets of locomotive equipment compartments and ventilation systems. The current mechanical filter has problems such as low filtration efficiency, insufficient dust filtration, and small ventilation volume. At the same time, if the amount of wind and sand is large, the filter device will be saturated. If it is not cleaned in time, the particles may enter the car with the wind , causing secondary pollution. Contents of the invention [0003] The technical problem to be solved in the present invention is to overcome the existing defects, provide a k...
