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.

Embodiment 1

[0049] Such as figure 2 As shown, a dust suction and filtration method for the dust collection system of a track grinding vehicle, which integrates the primary filter space 2 and the secondary filter space 3 for dust suction and filtration, that is, a The primary filter space 2 and the secondary filter space 3 connect the intake pipe 6 with the primary filter space 2, the air outlet pipe 7 communicates with the secondary filter space 3, and a plurality of filter cartridges 8 are installed in the secondary filter space 3; When vacuuming, the high-temperature dust gas is first sent into the primary filter space 2 through the intake pipe 6, and the dust gas collides with the surrounding wall of the primary filter space 2 for primary filtration, and then enters the secondary filter space for use. The filter cartridge 8 performs secondary filtration to the dust gas.

[0050] The above-mentioned primary filter space 2 is mainly to filter out the high-temperature dust with a large ...

Embodiment 2

[0059] Such as Figure 8 to Figure 10 As shown, the difference from Embodiment 1 is that the dust interception impeller 9 is installed at the air outlet 61 of the air intake pipe of the primary filter space 2; the dust interception impeller 9 includes an axle 91 and a plurality of dust interception blades 92; The dust gas sprayed into the tuyere 61 first impacts the dust-cutting blade 92 of the dust-cutting impeller 9 and makes the dust-cutting impeller 9 rotate. After the blade 92 collides with the dust intercepting blade 92, part of the dust falls under the action of gravity, which can make the dust gas complete the first filtration in the first-stage filtering space 2 .

[0060] The installation mode of described dust interception impeller 9 comprises following two kinds:

[0061] One is to install the wheel shaft 91 of the dust-intercepting impeller 9 above the air inlet pipe outlet 61, so that the bottom of the dust-intercepting impeller 9 is facing the air outlet, as ...

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...
