Abstract
The utility model relates to an enhanced air exhausting and supplying machine for coal mines. Both ends of two to four parallel and collapsible wind boxes are provided with front bottom plates of the wind box and back bottom plates of the wind box, and are provided with air inlet valves and air exhausting valves. The centers of the front bottom plates of the wind box are fixed with piston rods which are connected with crankshafts. The back bottom plates of the wind box are connected with an air storage chamber through connection pipes, and are provided with externally connected pipe openings for exhausting air and air exhausting valves. Under the function of an electric motor or other power devices, the utility model drives the crankshafts to start the piston rods and the collapsible wind boxes press the air into the air storage chamber. Under the definite air pressure, the air is supplied to the required places through a pipeline which is connected with the externally connected pipe openings for exhausting air. The utility model is especially suitable for wells of coal mines.
Description
Affiliated technical field
The utility model relates to a kind of conveying air assembly, the powerful dispatch air engine in a kind of specifically colliery.
Background technique
At present, carry air generally to adopt venter or blower, but can not reach needed air wind-force fully in special occasion, especially the mine of Cai Meiing needs dispatch to enter air, methane gas is discharged, adopt to have now and send air assembly but can not tackle the problem at its root, gas explosion accident happens occasionally, brought very big trouble to coal mining industry, and this problem fails all the time effectively to be solved.
Summary of the invention
The utility model provides a kind of colliery powerful dispatch air engine, can air be delivered to needed place from exhaust pipe mouth by strong pressurized air mode.
The technological scheme that the utility model adopted is: two to four collapsible bellows are installed together side by side, the two ends of collapsible bellows are provided with base plate and bellows noseplate behind the bellows, be provided with the 3-4 one slide rail all around, one end of slide rail is fixed on the periphery of base plate behind the bellows, the other end passes the slide rail cover that bellows noseplate surrounding is fixed, the end place interconnects by connecting plate, vertical piston sleeve of the center fixation of its connection, be provided with 2-4 suction valve above the bellows base plate of collapsible bellows, a piston rod is fixed in the center portion, and pass piston sleeve, bearing housing connecting sleeve by its tail end is on bent axle, the center of bent axle is provided with belt pulley and rack-mounted motor links together, can be under the effect of motor, drive crankshaft operation, the two ends of bent axle are connected with the piston rod of collapsible bellows respectively, bent axle adopts bearing support to be fixed on the frame, the base plate center is provided with outlet valve behind the bellows of collapsible bellows, adopt connecting tube to be connected with the gas storage chamber of afterbody, the outside of gas storage chamber is provided with an outlet valve and is provided with the external mouth of pipe of exhaust, and the equal integral body of collapsible bellows and gas storage chamber is fixed on the frame.
Feature of the present utility model also is the air displacement of the outlet valve air displacement of collapsible bellows greater than gas storage chamber, can form air pressure.
Power plant of the present utility model can use motor, also can adopt other power plant.
When the utility model uses, behind actuating motor or other power plant, driving bent axle by belt pulley rotates, the piston rod that is connected is under the effect of bent axle, twitch collapsible bellows, and the suction valve on the bellows noseplate is opened automatically when collapsible bellows are outwards taken out and is entered air, suction valve cuts out when inwardly pressing air, the outlet valve at base plate center is opened behind the bellows, and the air in the bellows is compressed to the gas storage chamber of afterbody, when bellows are outwards taken out, exhaust valve closure, work repeatedly, when the gas storage chamber of its afterbody reached certain pressure at air, its outlet valve is opened by the external mouth of pipe of exhaust can deliver to air needed place.
The beneficial effects of the utility model are: collapsible bellows working in reciprocating mode arranged side by side, air quantity is big, simultaneously air is pressed into gas storage chamber, and the outlet valve air displacement of bellows is greater than the outlet valve air displacement of gas storage chamber, further air pressure is strengthened, the vent connection mouth that makes it afterbody is the adjunction air duct as required, and air pressurized is delivered to needed place.
