Filter for railway locomotive vehicle

Abstract

The invention discloses a filter for a railway locomotive vehicle, which comprises a filter core and a frame body assembly, wherein the filter core consists of an upper clamp, a lower clamp and a plurality of filter bodies in parallel arrangement, the filter bodies are respectively connected between the upper clamp and the lower clamp, a ventilation passage is respectively formed between every two filter bodies, each filter body comprises a front flow guide plate, a middle spiral flow plate and a back air outlet plate, the front flow guide plate and the back air outlet plate are mutually parallel, both ends of the middle spiral flow plate are respectively connected with the tail part of the front flow guide plate and the head part of the back air outlet plate, the middle spiral flow plate corresponds to the lower clamp, the frame body assembly is provided with an accommodating space, and the filter core is accommodated and arranged in the accommodating space and is mutually connected with the frame body assembly through the upper clamp and the lower clamp.

Description

technical field [0001] The present invention relates to an air filter, in particular to a filter for railway rolling stock. Background technique [0002] Ventilation filters have basically used filters of two structures. [0003] One is an air filter with louvers and a filter mesh structure. The louvers are herringbone louvers with a double V structure, and the filter mesh is a filter mesh of palm straw mats or non-woven fabrics or stainless steel wires. It is a herringbone structure, the wind cannot enter the car in a straight line, but enters the car through the labyrinth path formed by the herringbone shutters. After the dust brought by the wind hits the herringbone shutters, some of them will fall and can be removed after passing through the filter. Part of the dust, so it has a certain dust removal effect on the wind entering the car. However, after the dust brought by the wind hits the herringbone blinds and falls, there is no place to collect them, and they cannot b...

AI Technical Summary

Problems solved by technology

However, after the dust brought by the wind hits the herringbone blinds and falls, there is no place to collect them, and they cannot be discharged outside the car. They accumulate between the blinds and the filter screen, and some dust will adhere to the filter screen, which requires frequent maintenance and cleaning. Otherwise, the dust filtering performance will be reduced, thereby increasing the possibility of dust entering the car, and the filter screen needs to be replaced when necessary, and its resistance is large, energy consumption is large, and the filtering effect is not ideal, which directly affects the performance and life of electrical components and increases Locomotive operation and maintenance workload and cost

[0004] The other is the tube curtain air filter, which has good filtration performance and maintainability, but the manufacturing process is complicated, including the front guide body, the middle swirl body, and the rear air outlet body, but these bodies have no Formed into one, the position and fixed welding between each other are more cumbersome, and sometimes the manufactured products are difficult to accurately guarantee and reflect the design requirements
