Abstract
The utility model relates to a supporting device of a coal grinding machine in a fire plant, and in particular to a stone coal clearing and sorting system for clearing and sorting the waste stone coal in the coal grinding machine, which comprises a material sorting device that is arranged between a vacuum pump and a vacuum conveying pipeline, wherein, the material sorting device comprises a stone coal cabin and a fine powder cabin; an entrance of the stone coal cabin is communicated with the vacuum conveying pipeline; fine powder passages which are communicated with each other are arranged between the stone coal cabin and the fine powder cabin; the top part of the fine powder cabin is connected with the vacuum pump through a dust catcher; the bottom part of the stone coal cabin is provided with a stone coal unloading port which is controlled by an unloading valve; and the bottom part of the fine powder cabin is provided with a fine powder unloading port which is controlled by the unloading valve. When clearing and sorting the stone coal, the stone coal clearing and sorting system separates the coal powder and the coal particles, so that the coal powder and the coal particles can be used continuously, thereby saving the energy source, and reducing the environmental pollution.
Description
Technical field
The utility model relates to the corollary equipment of the coal pulverizer in a kind of thermal power plant, specifically is that a kind of waste material stone coal to coal pulverizer is cleared up and the stone coal of sorting cleaning separation system.
Background technology
Existing pebble coal vacuum clearing system generally includes stone coal collecting device and the vacuum conveyer tube road that is connected with the stone coal collecting device, the end on vacuum conveyer tube road is provided with a stone coal bunker usually, the stone coal is realized separating of stone coal and dust-contained airflow through mixed airflow cyclonic separation and gravitational settling in the stone coal bunker, the stone coal falls in the storehouse, dust-contained airflow falls into the stone coal bunker through isolating dust behind the deduster, also contain a large amount of coal dusts in the stone coal and the coal grain is not separated, work as waste disposal, both waste the energy, also polluted environment.
Summary of the invention
The pebble coal vacuum clearing separation system that problem to be solved in the utility model provides a kind of energy savings, reduce to pollute, can separate a large amount of coal dusts and coal grain from the stone coal.
Pebble coal vacuum clearing separation system of the present utility model includes the material sorting device between vavuum pump and vacuum conveyer tube road, material sorting device comprises a stone coal bunker and a fine powder storehouse, the inlet of stone coal bunker communicates with the vacuum conveyer tube road, be provided with the fine powder passage that is interconnected between stone coal bunker and the fine powder storehouse, top, fine powder storehouse is connected with vavuum pump by deduster, be provided with the stone coal discharge port of controlling by discharge valve in the bottom of stone coal bunker, be provided with fine powder discharge port in the bottom in fine powder storehouse by discharge valve control.
Near the opening of above-mentioned fine powder passage, be provided with a controllable register, one end of controllable register is hinged on the standing part of material sorting device, between the standing part of controllable register middle part and material sorting device, also be connected with adjusting screw(rod), the size of aperture between the angle position that can change controllable register by stretching of adjusting screw(rod) and controllable register and the fine powder passage.
Pebble coal vacuum clearing separation system of the present utility model is when the stone coal of cleaning and sorting, the spoil that granularity is big in the stone coal, density is big is in the sedimentation of stone coal bunker elder generation, and the coal dust grain that granularity is little in the stone coal, density is little is inhaled in the fine powder storehouse, pass through deduster, sedimentation in the fine powder storehouse, also contain in the stone coal a large amount of coal dusts and coal grain separated come out, can continue to utilize, save the energy, reduced the pollution of environment.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
The material sorting device of pebble coal vacuum clearing separation system of the present utility model as shown in the figure includes stone coal bunker 1 and the fine powder storehouse 2 that is communicated with by fine powder passage 3, the charging aperture of stone coal bunker communicates with the vacuum conveyer tube road 4 that is connected the stone coal collecting device, top, fine powder storehouse is connected with vavuum pump by deduster 5, be provided with the stone coal discharge port of controlling by discharge valve 11 in the bottom of stone coal bunker 1, be provided with fine powder discharge port 21 in the bottom in fine powder storehouse 2 by discharge valve control.
Near the opening of fine powder passage 3, be provided with a controllable register 6, one end of controllable register is hinged on the stationary housing of material sorting device, between the stationary housing of controllable register middle part and material sorting device, also be connected with adjusting screw(rod) 7, the size of aperture between the angle position that can change controllable register by stretching of adjusting screw(rod) and controllable register and the fine powder passage 3.
At the pebble coal vacuum clearing separation system during at the cleaning and the stone coal of sorting, the vacuum conveyer tube road is delivered into spoil first sedimentation in stone coal bunker 1 that granularity is big, density is big in the stone coal in the stone coal bunker 1, the coal dust grain that granularity is little in the stone coal, density is little is inhaled in the fine powder storehouse 2 by the fine powder passage, deduster 5 isolated coal dust grains fall into 2 bottoms, fine powder storehouse, and clean air is discharged through vavuum pump.
By stretching of adjusting screw(rod) 7, controllable register 6 is rotated around jointed shaft, thereby the size of aperture between the angle position of change controllable register and controllable register and the fine powder passage 3, so just can be to regulating by the air-flow of fine powder passage 3, and then the size that enters the material particles in the fine powder storehouse is regulated.
Stone coal in being deposited on stone coal bunker and fine powder storehouse and coal dust particle reach a certain amount of after, can open discharge valve in each bin two kinds of materials after with sorting and draw off respectively.
