The utility model discloses an explosion-proof device, which comprises a cyclone (1), a door cover (2) and a door frame (3), wherein the door frame (3) is arranged on the wall of the cyclone (1), and the upper part of the door cover (2) is rotatably connected with the upper part of the door frame (3). The explosion-proof device provided by the utility model has the beneficial effects that when pulverized coal explodes in explosion limit, the door cover (2) is lifted, and gas is timely removed, thereby ensuring that a decarburization furnace is not blown up; after the gas is removed, the door cover (2) covers the door frame (3) again under the action of gravity, thereby ensuring the safety of equipment and personnel; and meanwhile, the structure is simple, the installation and use are convenient, and the work efficiency is high.
Description
Technical field
The utility model relates to a kind of flameproof apparatus.
Background technique
Gangue be mine and the coal washing process in unnecessary solid waste, be a kind of lower with a kind of carbon content of coal seam association in coalification course, than the hard black gray expandable rock of coal.Generally whenever adopt the 1t raw coal and discharge about spoil 0.2t, output is huge.Can be used as novel metope thermal insulating material etc. through the bastard coal building stones that obtain after grinding and the decarburization.Because contain carbon and some other inflammable matters in the gangue, so in whole decarbonization system, may blast under certain conditions, for whole system and producers' safety, it is necessary adding explosion protection system in decarbonization system, also is necessary.
Summary of the invention
The purpose of this utility model provides a kind of flameproof apparatus of blasting of preventing when using coal-gangue decarburizing system.
For addressing the above problem, the technical solution of the utility model is: a kind of flameproof apparatus, comprise door closure and doorframe, and the top of described door closure and the top of doorframe are rotationally connected.When blasting in coal dust is in explosion limit, door closure is started, and gas is in time got rid of, and the assurance decarbonizing furnace is not gone up, and after gas was discharged, door closure covered on doorframe again owing to action of gravitation again.
As further improvement of the utility model, also comprise safety enclosure, safety enclosure is installed on the cyclone cylinder and covers doorframe and door closure, described safety enclosure comprises housing, protective net, cat ladder and manhole door, the part that safety enclosure is connected with cyclone cylinder is housing, and the face relative with cyclone cylinder is protective net, and described cat ladder is installed on the housing, manhole door is located at the top of safety enclosure, is provided with the manhole door closure on the manhole door.Safety enclosure can effectively stopped it when the solid that bulk is arranged flies out, and guarantees staff's safety, and the people can enter safety enclosure by cat ladder from manhole door simultaneously, checks in the explosion-proof valve whether blocked by material, guarantees effective work of explosion-proof valve.
As further improvement of the utility model, it is relative with the whirlwind mouth that described doorframe, door closure and safety enclosure are positioned at the cyclone cylinder top.Door closure is relative with the whirlwind mouth, and be convenient to the explosion time door closure and started, be that gas is in time discharged.
Further improve as of the present utility model, described door closure and doorframe inboard are provided with high-temperature-resistant layer.High-temperature-resistant layer is that Steel Fibre strengthens castable refractory, before the castable construction, brush the thick bituminous paint of 2mm at bent part, prevent from getting rusty, round steel bent part corresponding spacing is staggered, be welded on door closure and the doorframe inwall, door closure and doorframe inwall stick calcium silicate board, calcium silicate board surface brush one deck water-proofing agent in the castable refractory contact, carry out castable again and build by laying bricks or stones, prevent like this door closure and doorframe owing to high temperature deformation reduces sealing, high-temperature-resistant layer increases the weight of door closure simultaneously, be conducive to after gas is discharged, door closure covers on doorframe.
To sum up, the beneficial effects of the utility model are: both can prevent that equipment from being blown up, can guarantee again staff's safety.Simultaneously simple in structure, it is convenient to install and use, high working efficiency.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
To shown in Figure 7, a kind of flameproof apparatus comprises cyclone cylinder 1 such as Fig. 1, door closure 2, and doorframe 3 and safety enclosure, it is relative with whirlwind mouth 11 that doorframe 3, door closure 2 and safety enclosure are positioned at cyclone cylinder 1 top; Doorframe 3 is installed on cyclone cylinder 1 barrel, and the top of the top of door closure 2 and doorframe 3 is rotationally connected, and door closure 2 and doorframe 3 inboards are provided with high-temperature-resistant layer 4, is supported by the round steel bent part 10 that is located on door closure 2 and the doorframe 3.Safety enclosure is installed on the cyclone cylinder 1 and covers doorframe 3 and door closure 2, safety enclosure comprises housing 5, protective net 6, cat ladder 7 and manhole door 8, the part that safety enclosure is connected with cyclone cylinder 1 is housing 5, the face relative with cyclone cylinder 1 is protective net 6, described cat ladder 7 is installed on the housing 5, manhole door 8 is located at the top of safety enclosure, is provided with manhole door closure 9 on it.High-temperature-resistant layer 4 is that Steel Fibre strengthens castable refractory, before the castable construction, brush the thick bituminous paint of 2mm at bent part 10, prevent from getting rusty, round steel bent part 10 corresponding spacing are staggered, and are welded on door closure 2 and doorframe 3 inwalls, and door closure 2 and doorframe 3 inwalls stick calcium silicate board, calcium silicate board surface brush one deck water-proofing agent in the castable refractory contact carries out castable again and builds by laying bricks or stones.
When using this flameproof apparatus, whirlwind mouth 11 is connected with decarbonizing furnace, coal dust content is enough large in decarbonizing furnace, mixes the mixture that forms in the explosion limit scope with air and just may blast.When blasting, the gas of expansion enters cyclone cylinder 1 by whirlwind mouth 11, and this moment, door closure 2 was started under powerful airflow function, and gas is discharged; Be equipped with high-temperature-resistant layer on door closure 2 and the doorframe 3, its deadweight is increased, after expanding gas was discharged from, door closure 2 covered again on doorframe 3 under action of gravitation, thereby avoided the decarbonizing furnace damage of being exploded.
When the solid that bulk is arranged flies out when entering safety enclosure from door closure 2, stopped by the protective net 6 on the safety enclosure, prevent from personnel are damaged.
At ordinary times in use, the manhole door 9 at safety enclosure top is closed, not permission personnel enter, when needs overhauled flameproof apparatus, the staff just can open manhole door 9, entered from manhole door 9, enter safety enclosure by cat ladder 7, flameproof apparatus is overhauled, check in the flameproof apparatus whether blocked by material, guarantee effective work of flameproof apparatus.
