Background
High-concentration dust in mine workplaces always troubles the safety production of coal mines and the health of workers. The coal dust has explosiveness, and even gas explosion and mine fire can be caused. When gas explosion occurs, gas coal dust explosion is formed, and serious economic loss and casualties are caused. Workers exposed to high-concentration dust workplaces for a long time also cause pneumoconiosis, the underground visibility is reduced, the interference is caused to the workers in correctly operating mechanical equipment, and potential safety hazards are caused. Meanwhile, high-concentration dust can reduce the service life of mechanical equipment and increase the production cost. The dust removal technology is one of the main tasks in 'one ventilation and three prevention' work, and is an important technical measure for improving the underground working environment of the coal mine and ensuring the safe production of the coal mine. Therefore, various dust removal and prevention technical equipment are in endless, and the dust prevention level of the mine is also effectively improved. But dust keeper can receive the influence of roof pressure, and along with the extension of tunnel service time, sunken phenomenon can appear in the tunnel roof, and roof pressure direct action can cause dustproof air door to warp the damage on dust keeper, influences the normal use of equipment, and the spraying angle that originally adjusted simultaneously also can change along with the increase of tunnel deflection, influences the spraying effect. In the prior art, the spraying device is mostly fixed on a roadway top plate, and the dynamic pressure of the roadway has great influence on the spraying direction. And dust keeper is mostly rigid among the prior art, and when the tunnel roof sinks, dust keeper very easily received the damage. Therefore, the research on the underground coal mine deformation-resistant dustproof device has important significance for improving the dustproof level of the mine.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a colliery is anti-deformation dust keeper in pit, through the spring coupling between slip back timber and the dust screen in order to realize that it slides from top to bottom, effectively alleviate roof pressure to dust collector's influence. The utility model adopts the technical scheme as follows:
the utility model provides a colliery is anti dust keeper that warp in pit, includes main frame and dust screen, the dust gate has been seted up on the dust screen, the main frame top is provided with the slip back timber, the both ends of slip back timber are fixed with the vertical connection arm, the slip back timber passes through vertical connection arm and main frame both sides sliding connection, be connected with anti expanding spring between slip back timber and the main frame top, be fixed with atomizer on the back timber, air duct hole, belt hole and cable hole have still been seted up on the dust screen.
The nozzle of the spraying device has an angle of incidence of 60 degrees.
The hole spacing of the dust screen is at least 120 meshes.
Compared with the prior art, the utility model discloses the beneficial effect who has does:
1. the utility model discloses a set up anti expanding spring on the slip back timber and between the main frame, the connection of slip back timber and main frame sets up to sliding connection simultaneously, can turn into elastic deformation with the rigidity deformation that tunnel roof pressure acted on dust keeper, has avoided dust keeper's destruction effectively, improves dust keeper's life-span.
2. The utility model discloses set up atomizer on sliding beam, open the back and spray water smoke to the dust screen, form full section water curtain, play the effect of filtering the dust fall comprehensively.
3. The utility model discloses reserved equipment holes such as dryer hole, belt hole and cable hole on the dust screen, when guaranteeing dirt-proof, do not influence all the other production work in the tunnel.
To sum up, the utility model discloses the installation is simple and convenient, and equipment removes conveniently. The anti-deformation capacity of the dust-proof device is greatly improved, and the long-term stable and efficient use of the dust-proof device in a roadway is ensured. The mine dust-proof device has the advantages of low cost, good effect and durable equipment, and can effectively improve the dust-proof level of a mine and ensure the physical and mental health of coal miners.
Drawings
FIG. 1 is a schematic structural view of the present invention;
wherein: the device comprises a main frame 1, a dustproof net 2, a dustproof door 3, a sliding top beam 4, a vertical connecting arm 5, an anti-expansion spring 6, a spraying device 7, an air duct hole 8, a belt hole 9 and a cable hole 10.
Detailed Description
