Dust collection and filtration method for rail grinding vehicle dust collecting system

Abstract

The invention discloses a dust collection and filtration method for a rail grinding vehicle dust collecting system. The method integrates a first stage filtering space and a second stage filtering space together for dust collection and filtration, that is, the first stage filtering space and the second stage filtering space are disposed inside one box body, an air inlet pipe is communicated with the first stage filtering space, an air outlet pipe is communicated with the second stage filtering space, and a plurality of filter cylinders are installed in the second stage filtering space; duringdust collection, high-temperature dust gas is sent into the first stage filtering space through the air inlet pipe for collision with the circumferential wall of the first stage filtering space to achieve first stage filtration, and then the filtered dust gas enters the second stage filtering space for second stage filtration by the filter cylinders. The method provided by the invention mainly hasthe advantages that the total installation space is greatly reduced, the installation application range in various rail grinding vehicles is expanded, and on the premise of meeting the requirements of first stage filtration, the first stage filtering space is reduced and simplified.

Description

technical field [0001] The invention relates to a dust suction and filtration method, in particular to a dust suction and filtration method for a dust collection system of a rail grinding vehicle. Background technique [0002] During the operation of the rails, on the one hand, the treads of the trains are constantly worn against the non-uniformity of the upper surface of the rails, which makes the rails gradually become inconsistent with the specified standard shape. On the other hand, the most important thing is that on the curve, the left wheel and the right wheel of the train wheel set can only travel the same distance, but actually travel a different distance, which is likely to cause wave wear on the rail. In both cases, it is necessary to use a track grinding vehicle to polish and maintain the rails. [0003] During the grinding operation of the rail by the rail grinding vehicle, a large amount of iron filings will be generated. These iron filings should not be allo...

AI Technical Summary

Problems solved by technology

The dust suction method in the above-mentioned patent documents is designed by adopting the method of phase separation of primary filtration and secondary filtration, that is, a cyclone separator is additionally installed outside the secondary filtration device. Within a certain space limit, the cyclone separator of the primary filter device occupies a large installation space, so the volume of the secondary filter device is small, resulting in an excessive number of filter cartridges installed in the secondary filter device. Less, reducing the filtering effect of the secondary filter;

[0009] 2. In the above-mentioned patent documents, due to the design of the phase separation of the first-stage filter and the second-stage filter, the structure of the entire dust collection system will also be too complicated, thereby increasing the manufacturing cost and maintenance cost.
