Abstract
The utility model relates to a windwater spraying device for spraying and dust prevention of an underground coal mining machine and a hydraulic support of a fully-mechanized coal mining machine. The windwater spraying device is a spraying body which is provided with a water channel for communicating the front and rear ends of the spraying body and a wind channel for communicating the front end at the side surface thereof, a water inlet pipe is connected at the rear end of the spraying body, a spraying core is connected at the front end of the spraying body, a water yielding channel at the middle part of the spraying core is communicated with the water channel, a plurality of air holes are distributed on the spraying core around the circumstance of the water yielding channel, the air holes is communicated with the wind channel of the spraying body, a spraying head with a front spraying port is fixed at the front part of the spraying core, and the side surface of the spraying body is connected with a wind inlet pipe communicated with the wind channel of the spraying body. A water outlet of the spraying device is additionally arranged for improving the atomizing effect; moreover, the spraying distance is far, water mist covering area is large and the dust removing effect is good; meanwhile, the requirements to water quality are not strict, and the outlet of the spraying head is not easy to be plugged; the operation is simple, and the movement is convenient; in addition, wind power can blow away local gas, thus ensuring coal mine safety.
Description
Technical field:
The utility model relates to a kind of geomantic omen atomization mechanism, is used for the spray dust prevention of silo shearer, fully-mechanized digging machine hydraulic support, prevents dust in the more place of dusts such as belt transfer point that also can be used for ground coal preparation plant.
Background technology:
At present, the spray dust prevention device that existing silo shearer, fully-mechanized digging machine hydraulic support etc. are located generally is to adopt water under high pressure directly to spray, and the spraying distance is near, and the water smoke coverage rate is little, can not effectively dust be caught, and dust-laying effect is poor.Simultaneously, tighter to water quality requirement, the shower nozzle outlet is stopped up easily.
Summary of the invention:
The purpose of this utility model provides a kind of geomantic omen atomization mechanism, solves the defective that former atomization mechanism spraying distance is near, the water smoke coverage rate is little, dust-laying effect is poor, the shower nozzle outlet is stopped up easily.
The purpose of this utility model realizes as follows: a body spray is arranged, body spray has the wind passage that the aquaporin that is communicated with the front and back end and side are communicated with front end, the body spray rear end connects water inlet pipe, the body spray front end connects the spraying core, the exhalant canal at spraying core middle part is communicated with the aquaporin of body spray, the spraying core is furnished with some ventholes around the aquaporin border, the wind channel connection of venthole and body spray, the fog-spray nozzle that has fore nozzle is fixed on spraying core front portion, and the body spray side connects the blast pipe with body spray wind channel connection.During use, high-pressure blast is from the venthole ejection of spraying core, and the fog-spray nozzle inner chamber forms negative pressure, and current mix generation water smoke from the exhalant canal sucking-off with air-flow, and water smoke sprays by fog-spray nozzle.
Spraying core rear end face has ring groove, and each venthole rear end of spraying core is communicated with groove, and the wind passage of body spray is communicated with groove.
Fog-spray nozzle is the hat-shaped structure that has along the axis direction joint-cutting, and water smoke can form fan-shaped plan after by joint-cutting and spray to except that dirt pits.
The beneficial effects of the utility model are: pressure wind has increased the kinetic energy of atomization mechanism delivery port, has improved atomizing effect, can effectively dust be caught, thereby play the purpose of depositing dust; And the spraying distance, the water smoke coverage rate is bigger, and dust-laying effect is good; Owing to do not use the structure of direct micropore water spraying atomization, not tight to water quality requirement, the shower nozzle outlet is difficult for stopping up; Simple to operate, conveniently moving; Wind-force can also dispel local gas, guarantees safety of coal mines.
Description of drawings:
Accompanying drawing is the structural representation of the utility model geomantic omen atomization mechanism.
The specific embodiment:
With reference to accompanying drawing, a body spray 5 is arranged, body spray 5 has the wind passage that the aquaporin that is communicated with the front and back end and side are communicated with front end, body spray 5 rear ends connect water inlet pipe 1 by nut 2, accompany pad 3 between water inlet pipe 1 and the body spray 5, body spray 5 front ends are by the spraying core 6 that is threaded, the exhalant canal at spraying core 6 middle parts is communicated with the aquaporin of body spray 5, spraying core 6 is furnished with some ventholes around the aquaporin border, spraying core 6 rear end faces have ring groove, each venthole rear end of spraying core 6 is communicated with groove, and the wind passage of body spray 5 is communicated with groove.The blast pipe 4 of body spray 5 sides by being threaded with body spray 5 wind channel connections is sealed with sealing ring between blast pipe 4 and the body spray 5.Fog-spray nozzle 7 is for to have along the hat-shaped structure of axis direction joint-cutting, and joint-cutting is a circular arc, and the fog-spray nozzle 7 that has the joint-cutting fore nozzle is fixed on spraying core 6 front portions by nut, between the end face of fog-spray nozzle 7 and spraying core 6 sealing ring is set.
