Cyclone filter cylinder combined type dust collecting device and steel rail polishing train comprising same

Abstract

The invention provides a cyclone filter cylinder combined type dust collecting device, and relates to the technical field of structure design of subway rail maintenance devices. The device is used tofilter dust and fume containing gas generated during the subway steel rail polishing process. In a primary filtering apparatus, a cyclone separator has a combined structure of a cylindrical cavity anda circular truncated cone cavity; one end of a first air inlet channel is connected to a first through hole, the other end is connected to a steel rail polishing device through a connection corrugated pipe; in a secondary filtering apparatus, multiple detachable filter cylinders are evenly arranged in a filter cavity, the bottom is connected to a second dust collection box, the filter cavity is communicated with the cylindrical cavity through a second air inlet channel, a power device is arranged on the exterior of the secondary filtering apparatus and is used to provide power for air flowing. After the dust and fume containing gas generated during the subway steel rail polishing process is purified by a primary separation device and a secondary separation device, the solid particles areremoved, the temperature is reduced, and the damage to the communication cables or air conditioners in a tunnel by high temperature gas is avoided.

Description

technical field [0001] The invention relates to the technical field of structural design of a subway track maintenance device, in particular to a cyclone filter cartridge combined dust collecting device and a rail grinding train equipped with the same. Background technique [0002] As we all know, with the increase of urban population year by year, especially in Beijing, Shanghai, Guangzhou and other cities with very large population density, the ground transportation in the city has become increasingly unable to meet people's travel. Due to its wide coverage and time guarantee, the subway has become the choice for more and more people to travel. The number of subways has increased year by year, and the carrying capacity of subways has risen sharply. In order to achieve efficient and reliable operation, the maintenance requirements and maintenance quality requirements for subway tracks have gradually become prominent. The subway is a rail vehicle and is located in a tunnel ...

AI Technical Summary

Problems solved by technology

In view of the above problems, it is necessary to regularly polish the subway tracks. However, most of the subway tracks are located in closed tunnels and are not placed in the atmosphere like trains or high-speed rails. The smoke and dust generated during the grinding operation of the subway tracks need to be treated in a timely and thorough manner. , otherwise it may affect the safety of subway vehicles

If the high-temperature abrasive debris generated by subway grinding operations is not handled in time, it will easily cause structural damage or even oxidation of the lines when it falls on the communication cables or air-conditioning devices in the tunnel, posing a great threat to the safety of subway traffic.

[0003] The technical problem that needs to be solved urgently is how to design a technical solution to solve the damage to the equipment in the tunnel caused by the high-temperature smoke and dust during the above-mentioned subway track grinding process
