Problems solved by technology

Due to the large difference in particle size of pulverized coal sprinkled on the railway roadbed, the large coal particle is about 10mm, and the small particle is dust below 0.005mm. The purposes of coal powder with different particle sizes are also different, but ordinary separators cannot If it is selected for separation, it needs to be equipped with screening equipment to recycle after separation; moreover, during the separation process of the existing separator, dust is easy to enter the vacuum pump, which affects the service life of the pump, the separation effect is not good, and the emitted gas There is still some dust in the air, which will cause certain pollution to the environment.

Embodiment Construction

[0029] In conjunction with accompanying drawing, the specific embodiment of the present invention is described further:

[0030] Such as figure 1 The special separator for removing coal powder spilled on the railway embankment shown includes two-stage separators connected through a curvature pipe 5, the first-stage separator is a cyclone separator 3, the second-stage separator is a bag filter separator 6, and the cyclone separator 3 Supported by the bracket 2, the bottom of the cyclone separator 3 is connected with an impeller unloader 1, and the top of the curvature tube 5 is equipped with an explosion-proof door 4. Wherein, the diameter of the curvature tube 5 is selected according to the delivery volume.

[0031] Such as figure 2 , 3 As shown, the cyclone separator 3 includes a cylindrical cylinder connected from top to bottom, a cone cylinder 34 and a blanking buffer cylinder 35. The large diameter end of the cone cylinder 34 is on the top and the small diameter end is...

Abstract

The invention belongs to the field of pneumatic transportation, particularly relates to a dedicated separator for cleaning scattered coal dust on a railroad bed, and aims to quickly and effectively select and separate the scattered coal dust on the railroad bed. The dedicated separator for cleaning the scattered coal dust on the railroad bed comprises two-stage separators connected through a curved tube, wherein the first-stage separator is a cyclone separator, and the second-stage separator is a cloth-bag filtration separator; the cyclone separator is supported by a stand; an impeller type unloader is connected with the bottom of the cyclone separator; an explosion door is mounted at the top of the curved tube. The dedicated separator disclosed by the invention comprises two stages, can screen the coal dust with different grain diameters at different stages, is higher in pertinence, beneficial to recycle of the screened coal dust and better in separation effect; the clean air emitted after being separated and filtered cannot pollute the air.

Description

technical field [0001] The invention belongs to the field of pneumatic transportation, and in particular relates to a special separator for removing coal powder spilled on a railway roadbed. Background technique [0002] At present, the spilled coal powder in the tunnels of my country's railway coal transportation line is quite serious, and the coal powder covers the roadbed, which directly affects the safe passage of railway coal transportation. For this reason, the railway department organizes a large number of personnel to manually clean the coal powder on the roadbed. Labor intensity is big like this, and efficiency is low. It has been proved that it is an effective method to lay pipelines in the tunnel and use a high vacuum pump to suck and clean the pulverized coal to the outside of the cave, but there is no matching special separator. Due to the large difference in particle size of pulverized coal sprinkled on the railway roadbed, the large coal particle is about 10m...
