Abstract
The utility model discloses a pneumatic bidirectional flashboard coal bucket which solves the problem that an existing coal bucket is easily blocked by the coal. The pneumatic bidirectional flashboard coal bucket is characterized in that a pneumatic bidirectional flashboard door is arranged in the middle of the coal bucket, the pneumatic bidirectional flashboard door comprises a flashboard fixing bracket, two flashboards, two cylinders, and two cylinder fixing bases, wherein the cylinders are fixed by the cylinder fixing bases on the flashboard fixing bracket, a piston rod of each cylinder is connected with each flashboard, an air pipeline I and an air pipeline II of the cylinders are respectively connected with a pneumatic reversing valve, and the pneumatic reversing valve is connected with an air storage tank. The pneumatic bidirectional flashboard coal bucket can be opened and closed in two directions, each flashboard is opened towards the two sides, the stroke of each flashboard is short, the power is high enough, each flashboard is rapidly opened and closed, an excellent sealing property is achieved, the pneumatic bidirectional flashboard coal bucket is widely applied to cutting off or switching of various buckets or pipelines and is particularly suitable for a coal bunker, and the problems of the phenomena of coal clogging and coal blockage in the operation of the coal bunker are effectively solved.
Description
Technical field
The utility model relates to a kind of coal bunker, relates to or rather a kind of coal bunker that uses pneumatic bidirectional flashboard.
Background technology
In the solid material process of conveying powdered, granular, block or its mixture, putty phenomenon happens occasionally, particularly at thermal powerplant, carry in raw coal process and often run into the sticky coal of coal breakage bucket, paulin coal, chute blockage, therefore need to block logistics, to facilitate maintenance.
That existing cutting device has is unidirectional, stroke long yielding, open and close effort, have a leakage again, some partial devices are in service protruding more, easily produce potential safety hazard, gap between some rail grooves is larger, because ature of coal is thin, in coal, there are the sticky foreign material such as ash etc., be bonded in rail groove, cause rear storehouse to hide coal, cause that plate is stuck, Guan Bushang.Affect follow-up equipment safety, economical operation.Particularly, at thermal powerplant, raw coal bucket material latch up phenomenon often occurs, affects safety production.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art a kind of pneumatic bidirectional flashboard coal bunker, dependable performance, flexible operation, easy to maintenance is provided.
The utility model comprises coal bunker, it is characterized in that arranging pneumatic bidirectional flashboard door in the middle of coal bunker, described pneumatic bidirectional flashboard door comprises flashboard fixed support, two flashboards, two cylinders, two cylinder permanent seats, cylinder is fixed on flashboard fixed support with cylinder permanent seat, and the piston rod of cylinder connects flashboard; Air pipe I, the air pipe II of cylinder connect respectively air operated reversing valve, and air operated reversing valve connects storage tank.
As shown from the above technical solution, pneumatic bidirectional flashboard of the present utility model can two-wayly open and close, and flashboard is opened to both sides, and gate travel is short, and power is sufficient, opens and closes rapidly, has more good sealing property; Can be widely used in blocking or switching of various hoppers or pipeline, be specially adapted to former coal bunker; Can effectively solve the operating fluffy coal of former coal bunker, chute blockage phenomenon, have a good application prospect.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1. coal bunker, 2. flashboard fixed support, 3. flashboard, 4. cylinder, 5. piston rod, 6. cylinder permanent seat, 7. storage tank, 8. air operated reversing valve, 9. air pipe I, 10. air pipe II, 11. air pipe II connection valves, 12. air pipe I connection valves.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises coal bunker 1, pneumatic bidirectional flashboard door.Described pneumatic bidirectional flashboard door comprises flashboard fixed support 2, two flashboards 3, two cylinders 4, two cylinder permanent seats 6, and cylinder 4 use cylinder permanent seats 6 are fixed on flashboard fixed support 2, and the piston rod 5 of cylinder 4 connects flashboards 3.Air pipe I 9, the air pipe II 10 of two cylinders 4 are converged respectively, by air pipe I connection valve 12, air pipe II connection valve 11, connect air operated reversing valve 8, and air operated reversing valve 8 connects storage tank 7.
