Internal combustion locomotive integrated air filter and filtering device with filter

Abstract

The invention relates to the technical field of railway locomotives, in particular to an internal combustion locomotive integrated air filter and a filtering device with the filter, and the front face of a box body is provided with an inclined strut avoiding structure which is embedded in an inclined strut on the side wall of the locomotive; a first-stage filtering element, a second-stage filtering element and a dust removal device are integrally installed in the inner cavity of the box body, the first-stage filtering element is connected with the dust removal device, the second-stage filtering element is installed on the inclined upper portion of the first-stage filtering element, installation flanges are installed on the two side edges of the box body, and the box body is installed on the side wall of the locomotive through matching of the installation flanges and bolts. The whole device is high in integration level and is modularly embedded into the side wall, so that the space utilization rate of the locomotive is improved, and drivers and passengers can conveniently pass through; the inclined strut avoiding structure is adopted, the second-stage filtering element is optimally designed based on the limited inclined strut space, the filtering area is increased, and on the premise that the filtering efficiency requirement is met, the air inlet resistance of the diesel engine is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of railway locomotives, in particular to an integrated air filter for a diesel locomotive and a filter device with the filter. Background technique [0002] In the process of developing a certain type of diesel locomotive, due to the limited layout of the locomotive, the air filtration system needs to be arranged on the side wall of the locomotive. Since the side wall of the locomotive with the side wall load-bearing structure has diagonal braces, the existing scheme is arranged in the on the side wall of the locomotive, such as figure 1 , 2 As shown, the locomotive walkway space is occupied, and the width D1 of the occupied lane is 245mm, which affects the passage of drivers and passengers, and requires separate installation of dust removal devices at other locations, which occupies a large area and is not conducive to modular assembly. Contents of the invention [0003] The technical problem to be solv...
