Abstract
The utility model discloses a gas arch breaker, which comprises plugging plates, a piston bush, a piston, a high-pressure gas tank, a blow-down valve and an admission pipe. The gas arch breaker is characterized in that the piston bush is inlaid in the wall of the high-pressure gas tank and extends into the high-pressure gas tank; the piston is jacked by a spring arranged at the bottom part of the piston bush and is plugged in the piston bush by the plugging plates at mouths of the piston bush; each plugging plate is a cylinder of which both ends are open; the plugging plates are fastened at the mouths of the piston bush through fastening screws; the bottom part of the piston bush is plugged and is communicated with a normal-pressure gas pipe extending out of the high-pressure gas tank; and the front half part of the wall of the piston bush is provided with a plurality of inlet holes. When arch breaking is needed, the piston is pushed by high-pressure gas inlet by the admission pipe to move to the bottom part of the piston bush, so that the piston is separated from the plugging plates, and at the time, the high-pressure gas in the high-pressure gas tank is ejected instantaneously by a cavity in the middle of the plugging plates to rush at a compacted material of the opening of a material bin, and therefore, the goal that the opening of the material bin is dredged is achieved.
Description
Technical field
The utility model relates to a kind of air cannon, is specifically related to a kind of air cannon of dredging the solid material of compacting in the storage bin with high pressure gas.
Background technology
In coal, grain, cement and Chemical Manufacture, often run into the solid material in the storage bin and should not trickle out owing to be compacted, what impact was produced normally carries out, be widely used at present the high pressure gas broken arch and dredge the storage bin Hatch Opening, 200920019778.1 of China Patent No. be called that " air cannon " and 200420064020.7 of China Patent No. are called " Arch-Breaking Device " although patent all be that high pressure gas with compression come broken arch storage bin Hatch Opening, but complex structure is stopped up by broken material bits easily.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of air cannon of simple in structure, unsuitable occluding device is provided.
The utility model is realized by following technological means: a kind of air cannon, comprise shutoff dish, piston bush, piston, high pressure gas holder, foul valve, normal pressure tracheae, air inlet pipe, it is characterized in that: described piston bush is embedded on the high pressure gas holder tank skin and puts in the high pressure gas holder, and piston is got lodged in the piston bush by the spring jack-up that is contained in piston bush bottom and the shutoff disk seal that is embedded in the piston bush oral area.
The cylinder that described shutoff dish is open at both ends also is fastened on the oral area of piston bush by holding screw.
Described piston bush bottom shutoff and be communicated with a normal pressure tracheae that stretches out high pressure gas holder.
The top of described piston is spheric, and the external diameter of piston equals the internal diameter of piston bush.
Forebody is provided with several induction openings on the wall of described piston bush.
Described foul valve is check valve, and this foul valve is embedded on the tank skin of high pressure gas holder and puts in the high pressure gas holder, is provided with mudhole at the valve wall near high pressure gas holder inwall place.
When this Arch-Breaking Device does not lead to high pressure gas, thereby piston is got lodged in the piston bush by the spring jack-up that is contained in piston bush bottom and the shutoff disk seal that is embedded in the piston bush oral area high pressure gas holder is sealed, when needing broken arch, pass into high pressure gas by air inlet pipe and enter high pressure gas holder, high pressure gas enter the front portion of piston bush by the induction opening on the piston jacket wall, when high-pressure gas pressure reaches certain value, the high pressure gas pushing piston is mobile to the piston bush bottom, so that piston contacts with the shutoff disk detachment, the high pressure gas moment of this moment in the high pressure gas holder rushes at the material that the material bin Hatch Opening is compacted by the ejection of the cavity in the middle of the shutoff dish, thereby reaches the purpose of dredging Hatch Opening; If enter the solid granule dirt in the high pressure gas holder, the spool that promotes foul valve can be discharged the solid granule dirt.
The utility model is simple in structure, manufacturing cost and use cost are all lower, easy to manufacture, very easily promotes.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the scope situation that does not break away from the protection of the utility model aim, can also make the concrete conversion of a lot of forms, these all belong within the protection domain of the present utility model.
Description of drawings
Accompanying drawing 1 is the not structural representation during broken arch of the utility model
Structural representation when accompanying drawing 2 is the utility model broken arch
Among the figure: 1-shutoff dish, the 2-piston bush, the 3-induction opening, the 4-piston, 5-high pressure gas holder, 6-go out dirty hole, 7-foul valve spool, 8-foul valve, 9-spring, 10-normal pressure tracheae, 11-air inlet pipe.
The specific embodiment
Below in conjunction with description of drawings and the specific embodiment the utility model is described in further detail:
Shown in accompanying drawing 1, accompanying drawing 2, a kind of air cannon, comprise shutoff dish 1, piston bush 2, piston 4, high pressure gas holder 5, foul valve 8, normal pressure tracheae 10, air inlet pipe 11, it is characterized in that: described piston bush 2 is embedded on high pressure gas holder 5 tank skins and puts in the high pressure gas holder 5, piston 4 by spring 9 jack-up that are contained in piston bush 2 bottoms and shutoff dish 1 shutoff that is embedded in piston bush 2 oral areas in piston bush 2.
Described shutoff dish 1 is for the cylinder of open at both ends and be fastened on the oral area of piston bush 2 by holding screw.
Described piston bush 2 bottom shutoff and be communicated with a normal pressure tracheae 10 that stretches out high pressure gas holder 5.
The top of described piston 4 is spheric, and the external diameter of piston 4 equals the internal diameter of piston bush 2.
Forebody is provided with several induction openings 3 on the wall of described piston bush 2.
Described foul valve 8 is check valve, and this foul valve 8 is embedded on the tank skin of high pressure gas holder 5 and puts in the high pressure gas holder 5, is provided with mudhole at the valve wall near high pressure gas holder 5 inwall places.
When this Arch-Breaking Device does not lead to high pressure gas, thereby piston 4 by spring 9 jack-up that are contained in piston bush 2 bottoms and shutoff dish 1 shutoff that is embedded in piston bush 2 oral areas in piston bush 2 to high pressure gas holder 5 sealings, when needing broken arch, pass into high pressure gas by air inlet pipe 11 and enter high pressure gas holder 5, high pressure gas enter the front portion of piston bush 2 by the induction opening 3 on piston bush 2 walls, when high-pressure gas pressure reaches certain value, high pressure gas pushing piston 4 moves to piston bush 2 bottoms, so that piston 4 disengages with shutoff dish 1, high pressure gas moment in this moment high pressure gas holder 5 rushes at the material that the material bin Hatch Opening is compacted by the ejection of the cavity in the middle of the shutoff dish 1, thereby reaches the purpose of dredging Hatch Opening; If enter the solid granule dirt in the high pressure gas holder 5, the spool 7 that promotes foul valve 8 can be discharged the solid granule dirt.
