Dustproof ventilation filtering device for railway track engineering

Abstract

The invention relates to the technical field of railway track engineering, in particular to a dustproof ventilation filtering device for railway track engineering, which comprises a ventilation box and a dust removal box, wherein an air outlet cavity, an exhaust cavity and a filtering cavity are arranged in the ventilation box, a motor is in key connection with the interior of the air outlet cavity, and a sleeve is in key connection with the exterior of the motor; the two ends of the sleeve are in key connection with rotating wheels, fan blades distributed at equal intervals are installed between the two rotating wheels through screws, air holes distributed at equal intervals are formed in the inner wall of one side of the filtering cavity, and the air holes communicate with the air outlet cavity. The dustproof ventilation filtering device has the beneficial effects that a dust removal bag in the dust removal box can preliminarily filter sucked air, so that dust and large-particle impurities are intercepted in the dust removal box, the dust and the large-particle impurities are prevented from entering the ventilation box, the risks of heating in the device and pipeline blockage are solved, and therefore, the service life of the device is greatly prolonged, and dust can be prevented from entering a room.

Description

technical field [0001] The invention relates to the technical field of railway track engineering, in particular to a dust-proof ventilation filter device for railway track engineering. Background technique [0002] The ventilation device is an independent air treatment system composed of an air supply system and an exhaust system. It is divided into two types: a ducted fresh air system and a ductless fresh air system. The ducted fresh air system is composed of a fresh fan and pipe fittings. Purified outdoor air is introduced into the room, and the indoor air is exhausted through pipes; the ductless fresh air system is composed of fresh fans, which also purify outdoor air into the room. [0003] Chinese patent number CN105757868B provides an integrated industrial ventilation filter device, which is characterized in that the integrated industrial ventilation filter device includes an air guide cover, and the air guide cover includes an "L" shaped hollow air guide cavity, the ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of dust-proof type ventilation filter device for railway track engineering, to solve the above-mentioned background technology that does not have dust-proof function, which will make Dust accumulates inside the device to block the pipes, and prevents the heat generated by the electrical components inside the device from dissipating, causing the device to heat up, and there is also a problem of causing dust to enter the indoor environment.
