Abstract
The utility model relates to chemical equipment, in particular to an emergency closing device for a wind pressure control system of a coal bunker gate of a coke furnace. The device comprises a compressed air main pipe, wherein an air cylinder opening main pipe and an air cylinder closing main pipe are connected onto the compressed air main pipe, and an air cylinder opening branch pipe and an air cylinder closing branch pipe are arranged on the air cylinder opening main pipe and the air cylinder closing main pipe respectively; and the air cylinder opening branch pipe and the air cylinder closing branch pipe are communicated with two ventilation ends of the cylinder respectively, an air cylinder emergency closing main pipe is added on the compressed air main pipe, an air cylinder emergency closing branch pipe is connected onto the air cylinder emergency closing main pipe and communicated with the ventilation end of the cylinder, and accordingly, a single group of emergency closing units is formed. The emergency closing device can perform emergency closing when the coal bunker gate cannot be closed normally, and coal leakage is prevented; and each coal bunker gate is configured with a group of emergency closing units, and a piston of the cylinder independently controls each coal bunker gate, so that normal operation of other coal bunker gates is not influenced when one coal bunker gate is damaged.
Description
Technical field
The utility model relates to chemical industry equipment, particularly coke oven coal bunker sluice gate wind pressure control system emergency shutdown device.
background technology
Existing coke oven coal bunker sluice gate is provided with magnetic valve or electric controling switch control wind path and realizes sluice gate and open, close, coke oven coal bunker sluice gate in use often occurs that coal bunker sluice gate wind path magnetic valve alters wind, the spacing malfunctioning or damage of electrical control, causing coal bunker sluice gate to be opened cannot close or extremely automatically open, coal charger fills rear coal bunker sluice gate and cannot cut out on time, coal charger leaves rear coal bunker sluice gate and the phenomenon such as extremely automatically opens and all can cause coal bunker sluice gate to leak coal, leak coal when serious up to tens tons tons even up to a hundred, not only cannot continue to produce, and leakage coal cleaning work amount is large, production efficiency significantly reduces.
Utility model content
The purpose of this utility model is to provide a kind of safety, reliable ground coke oven coal bunker sluice gate wind pressure control system emergency shutdown device of using.
The utility model solves the technical scheme that its technical problem adopts:
A kind of coke oven coal bunker sluice gate wind pressure control system emergency shutdown device, comprise compress wind supervisor, compress wind supervisor is upper connects that reservoir is opened supervisor and reservoir is closed supervisor, and reservoir is opened supervisor and reservoir and closed and on supervisor, be respectively equipped with reservoir unlatching arm and reservoir is closed arm; It is characterized in that described reservoir opens arm and reservoir and close arm and be communicated with two ventilation ends of cylinder respectively, compress wind supervisor is also provided with reservoir scram supervisor, on reservoir scram supervisor, be connected with reservoir scram arm, reservoir scram arm is communicated with the ventilation end of cylinder, the single group of composition scram unit.
Described single group scram unit is at least provided with one group.
Described reservoir unlatching arm and reservoir are closed arm and are provided with magnetic valve.
Described reservoir scram supervisor is provided with ball valve.
The beneficial effects of the utility model are:
1, on compress wind supervisor, set up reservoir scram supervisor, on reservoir scram supervisor, be connected with reservoir scram arm, reservoir scram arm is communicated with the ventilation end of cylinder, the single group of composition scram unit.Can in the time that cannot normally closing, coal bunker sluice gate carry out scram, the generation of anti-leak-stopping coal.
2, all supporting one group of scram unit of each coal bunker sluice gate, the piston of cylinder is controlled separately each coal bunker sluice gate, when certain coal bunker sluice gate infringement, does not affect other coal bunker sluice gates and normally works.
3, reservoir is opened arm and reservoir and is closed arm and be provided with magnetic valve, and magnetic valve can rapid reaction, is convenient to the quick opening and closing of coal bunker sluice gate.
4, reservoir scram supervisor is provided with ball valve, and ball-valve structure is simple, good seal performance, guarantees the effective scram of reservoir, and equipment operation is more reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state graph of the present utility model.
Embodiment
A kind of coke oven coal bunker sluice gate wind pressure control system emergency shutdown device as shown in the figure, comprise compress wind supervisor 1, on compress wind supervisor 1, connect that reservoir is opened supervisor 1 and reservoir is closed supervisor 3, reservoir is opened supervisor 2 and reservoir and is closed and on supervisor 3, be respectively equipped with that reservoir is opened arm 5 and reservoir is closed arm 6; Described reservoir unlatching arm 5 and reservoir are closed arm 6 and are communicated with two ventilation ends 9 of cylinder 10 respectively, compress wind supervisor 1 is also provided with reservoir scram supervisor 4, on reservoir scram supervisor 4, be connected with reservoir scram arm 7, reservoir scram arm 7 is communicated with the ventilation end 9 of cylinder 10, the single group of composition scram unit.Described single group scram unit is at least provided with one group.Can be according to coal bunker sluice gate quantity, the scram unit of supporting respective sets number.Described reservoir unlatching arm 5 and reservoir are closed arm 6 and are provided with magnetic valve 8.Described reservoir scram supervisor 4 is provided with ball valve 9.
When use, compress wind supervisor 1 passes into pressurized air, when coal charger sails near coal bunker sluice gate, opens reservoir and open the magnetic valve 8 of arm 5, pressurized air enters in cylinder 10, promote piston, piston is pushed coal bunker sluice gate open and is started to unload coal, and opens reservoir and close the magnetic valve 8 of arm 6 after coal charger is filled coal, pressurized air enters in cylinder 10, oppositely promote piston, piston is packed up coal bunker sluice gate and is stopped unloading coal, and coal charger transports.In the time that coal bunker sluice gate cannot close or extremely automatically open, open reservoir scram arm 7 by ball valve 9, pressurized air enters in cylinder 10, oppositely promotes piston, and piston is packed up coal bunker sluice gate, guarantees that coal bunker sluice gate closes, the generation of anti-leak-stopping coal.
