Intermittent spray foam carries out the spray head of depositing dust, belongs to coal mine equipment field.In particular to a kind of to pass through intermittent foam
Injection, comes into full contact with foam and dust, improves the spray head of dust-laying effect.
Background technique
Currently, the harm of dust is one of most important occupational hazards in Coal mine excavation, in order to prevent and treat underground powder
Dirt can carry out depositing dust using the method for atomizing de-dusting in digging operation, but this method can not effectively carry out continuing depositing dust, because
This uses relatively advanced foam dust suppression technology, by the way that foam jet in underground work face, adsorbs dust, due to
The surface area of foam is big, and absorption dust is high-efficient, but passes in and out the spray head sprayed all by the way of direct-injection to foam at present,
Spray regime is limited, and sprays continuously, is being directed to different environment, although there is various forms of spray heads, it is mainly used for flowing
Body is spraying foam and is being not suitable for, and due to the characteristic of foam, the pressure in injection cannot be excessive；
Publication number CN204564373U discloses the foam dust suppression spray head of a kind of injection of arc-shaped and angle adjustable, including
Ball nozzle (1), famale connector (2) and male contact (4) ball nozzle (1) include the scarce spherosome with end face, lack the end of spherosome
Face is provided with blind hole, and the dynamic cooperation of ball nozzle (1) is located in the arc groove of famale connector (2) front, and male contact (4) is sleeved on famale connector
(2) in, the front end face of male contact (4) is acted against on the end face of scarce spherosome；Scarce spherosome front, which is provided with, communicates composition with blind hole
Two strip grooves (7) of " V " font bar shaped spout.The spray head is oriented injection drop to underground by adjusting the angle of spray head
Dirt, but comprehensive injection cannot be carried out simultaneously, dustfall efficiency is low.
Publication number CN103240195A discloses a kind of foam dust suppression spray for preventing from falling off and capable of arbitrarily adjusting spray angle
Head.Mainly it is made of ball nozzle, famale connector, U-shaped card, male contact；The ball nozzle includes the scarce spherosome with end face,
The end face for lacking spherosome is provided with blind hole, lacks spherosome front and is provided with the strip groove for communicating with blind hole and constituting bar shaped spout, spherical shape spray
The dynamic cooperation of mouth is located in the arc groove of famale connector front, and male contact is sleeved in famale connector, and the front end face of male contact acts against scarce
On the end face of spherosome, it is provided with the central through hole communicated with bar shaped spout in the middle part of male contact, is symmetrically provided on famale connector outer wall
The jack of lower connection is fitted with U-shaped card in jack, and male contact, which corresponds to, is provided with annular groove at jack position.The injection of the spray head
Be it is continuous direct, foam cannot complete and underground dust progress Contact-sorption, reduce the dust-absorbing rate of foam.
Summary of the invention
In order to improve above situation, a kind of coal mine construction underground intermittence foam dust suppression spray head of the present invention provides a kind of logical
