Abstract
The utility model relates to a gangue delivery system during running of a coal grinding mill. The utility model comprises a coal grinding mill (1), a gangue hopper (2), a spiral conveyer (3), a first belt conveyer (4), a second belt conveyer (5), a hoister (6) and a gangue bin (7). The utility model is characterized in that one side of the coal grinding mill (1) is provided with the gangue hopper (2) and connected by pipes (12) with gangue hopper inlet pneumatic valves (11) between pipes. Outlet of the gangue hopper (2) is connected with the spiral conveyer (3) by pipes (13) with gangue hopper outlet pneumatic valves (8) between the pipes. Above the belt conveyer 5, the hoister (6) and the gangue bin (7) are equipped in turn. By introducing such a utility model, gangue discharged from the running of the coal grinding mill can be transported outside the boiler room, operational reliability of the coal grinding mill is improved, the problem that gangue releases dust is eliminated and production field environment is improved.
Description
Technical field
The utility model relates to a kind of coal pulverizer, more specifically to a kind of coal pulverizer stone coal delivery system in service.
Background technology
Jingyuan No.2 Electricity Generating Co., Ltd.'s boiler milling system is selected 5 of the HP863 type coal pulverizers that Shanghai Heavy Machinery Plant produces for use.Coal pulverizer is in operation and nonabradable materials such as coal backbone grit piece, spoil will be discharged from coal pulverizer, and the material of discharge is referred to as the stone coal.The stone coal mainly contains foreign material such as broken coal piece, gangue, stone and coal dust to be formed, and granularity is not more than 50mm, and bulk density is 1.2～1.5 tons/m
3The stone coal amount of every coal pulverizer discharge is 1～1.5t/h, and the temperature when discharging in coal pulverizer is about 150 ℃.The manual emission mode is adopted in the discharging of stone coal at present, and the stone coal that is about to coal pulverizer is discharged in the other slag case of coal pulverizer, after the slag case is full, manually the slag case is transported with fork truck, the stone coal is discharged into the stone coal yard stacks.Discharging modes severe contamination site environment like this.It is more to contain foreign material such as gangue, stone in the used coal of my company, the stone coal amount that coal pulverizer gives off is bigger, discharge about 40～100 tons 24 hours every days, the interface of slag case and coal pulverizer is frequently dismantled, be difficult to connecting, a large amount of coal dusts emit outward in causing discharging, and make the production scene dust from flying, personnel's work under bad environment damages employee's health.Discharging modes are unreliable in addition, influence the safe and stable operation of coal pulverizer, if the discharging of stone coal is untimely, can cause in the coal pulverizer and catch fire, cause coal pulverizer skirt closure assembly and screeding device serious wear, sometimes even the stone coal can take place stop up coal pulverizer import air channel, cause coal pulverizer to stop transport, the coal pulverizer maintenance cost will improve like this, and has increased the line service amount.
The utility model content
The purpose of this utility model provides a kind of coal pulverizer stone coal delivery system in service, in time the stone coal with coal pulverizer discharge in service is transported to outside the boiler room, improve the coal pulverizer operational reliability, solve stone coal discharging airborne dust problem, improve production on-site environment.
The utility model comprises coal pulverizer, stone coal bunker, conveying worm, No. 1 rubber conveyer, No. 2 rubber conveyers, elevator, stone coal bunker, stone coal bunker outlet pneumatic operated valve and stone coal bunker import pneumatic operated valves, be characterized in: be equipped with the stone coal bunker in each coal pulverizer side, the employing pipeline connects, and is provided with stone coal bunker import pneumatic operated valve between the pipeline.The outlet of stone coal bunker adopts pipeline to be connected with conveying worm, is provided with stone coal bunker outlet pneumatic operated valve between the pipeline.Above No. 2 rubber conveyers, be provided with elevator, stone coal bunker successively.Stone coal bunker side is provided with mud hole, is provided with peep hole at an upper portion thereof.
The utility model has the advantages that: can be in time the stone coal of coal pulverizer discharge in service be transported to outside the boiler room, have improved the coal pulverizer operational reliability, solved stone coal discharging airborne dust problem, improved production on-site environment.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is that the utility model coal pulverizer stone coal delivery system in service is arranged schematic diagram;
Fig. 2 is a stone coal bunker connection diagram in the utility model coal pulverizer stone coal delivery system in service.
The specific embodiment
In Fig. 1,2: each coal pulverizer 1 side is provided with stone coal bunker 2, adopt pipeline 12 to connect, be provided with stone coal bunker import pneumatic operated valve 11 between the pipeline, 2 outlets of stone coal bunker adopt pipeline 13 to be connected with conveying worm 3, be provided with stone coal bunker outlet pneumatic operated valve 8 between the pipeline, be provided with elevator 6, stone coal bunker 7 above No. 2 rubber conveyers 5 successively, the stone coal bunker is high 8.5 meters.3, No. 1 rubber conveyer 4 of conveying worm and No. 2 rubber conveyers 5 are arranged in the underground delivery tunnel.Conveying worm 3 tunnels are 2300 * 2000mm, and No. 1 rubber conveyer 4 tunnels are 2300 * 2800mm, and No. 2 rubber conveyer 5 tunnels are 2300 * 3000mm, and the width in tunnel and the degree of depth can according to circumstances change.The tunnel ventilation facility has utilized the facility of the ventilating and purifying air system of former coal pulverizer 1, has adorned two ventilation blowers but increase, a draining pump, and its effect strengthens the draining in tunnel.On stone coal bunker 2 and belt conveyor, atomizer is housed, in order to temperature and the minimizing dust from flying that reduces the stone coal.Stone coal bunker 2 sides are provided with mud hole 9, and its effect is: in case when the stone coal delivery system breaks down, can in time the stone coal in the coal pulverizer 1 be discharged.Be provided with peep hole 10 at an upper portion thereof, its effect is: observe the material level in the stone coal bunker 2.
Coal pulverizer stone coal delivery system in service is work like this: the stone coal in the coal pulverizer 1 at first enters in the stone coal bunker 2 of coal pulverizer 1 side through stone coal bunker import pneumatic operated valve 11 by pipeline 12, enter conveying worm 3 by pipeline 13 through stone coal bunker outlet pneumatic operated valve 8 again, be transported to rubber conveyer 4 then successively No. 1, on No. 2 rubber conveyers 5, at last the stone coal is transported in the outer elevator 6 of factory building, elevator 6 rises to the stone coal overhead about 9 meters high positions again, enter in the stone coal bunker 7, stone coal in the stone coal bunker 7 regularly enters truck, is transported to the stone dump and puts the field.
