Air filter device of composite cooler of haulage motor

Abstract

The invention discloses an air filter device of a composite cooler of a haulage motor. An air inlet of a shell is connected with an air outlet of a ventilator, an air outlet of the shell is connected with an air inlet of an oil-water cooler; a filter element is an electrostatic metal plate in a crossed and staggered grid plate structure, and is connected with a direct current supply and insulated with the shell; a dust collecting box is of a funnel structure with a door at one side, and is arranged at the downstream of the electrostatic metal plate. Tiny objects in airflow are adsorbed on the electrostatic metal plate by static electricity and are deposited in a funnel deposition box along a diversion trench under dual action of wind power and gravity of the tiny objects due to the included angle between the electrostatic metal plate and the axis of an air flue inside the shell and the crossed and staggered grid plate group structure, and thus the problems of dust retention and influence on heat dissipation of a cooling plate are effectively solved. At daily time, only the funnel-type dust collecting box with the door at the side needs to be cleaned, and under extreme conditions, the drawer-type electrostatic metal plate also can be easily taken down by opening the side door of the shell to clean. Thus, the cooling effect is greatly improved.

Description

technical field [0001] The invention relates to an air filter device for a composite cooler of a locomotive, belonging to the technical field of railway locomotives. Background technique [0002] In the ventilation system of the existing locomotive composite cooler, the air outside the car enters the air intake room of the roof through the centrifugal sedimentation filter and the side wall plate type coarse filter, and then cools the locomotive water radiator and oil radiator through the fan, and then into the atmosphere. The centrifugal sedimentation filter and the side wall plate-type coarse filter are aimed at the larger debris in the air and rainwater. After being filtered by the two, there will still be a lot of tiny objects such as dust entering, which will accumulate in the composite cooler. On the heat sink, affect heat dissipation. Therefore, a mesh filter device is installed between the ventilator of the composite cooler and the oil-water radiator to prevent dust...

AI Technical Summary

Problems solved by technology

When the mesh filter device is loose, the dust removal effect is not good; when the mesh is dense, the dust removal effect is better, but it will reduce the ventilation of the cooler and affect the heat dissipation effect

At the same time, the mesh filter device needs to be cleaned and replaced regularly, otherwise the filter element will accumulate too much dust, which will reduce the ventilation volume and heat dissipation effect of the cooler.

Since the mesh filter device is directly fixed in the compound cooler, the compound cooler needs to be disassembled when cleaning and replacing the filter element, which is very difficult to operate
