Description
Technical field
A kind of colliery construction underground intermittence foam dust suppression spray head of the present invention, is related to what a kind of underground coal mine used, passes through
Intermittent spray foam carries out the shower nozzle of depositing dust, belongs to coal mine equipment field.It is more particularly to a kind of to pass through intermittent foam
Injection, makes foam and dust fully contact, improves the shower nozzle of dust-laying effect.
Background technology
At present, in Coal mine excavation, the harm of dust is one of most important occupational hazards, in order to prevent and treat underground powder
Dirt, depositing dust can be carried out using the method for atomizing de-dusting in digging operation, but this method can not effectively carry out continuing depositing dust, because
This employs relatively advanced foam dust suppression technology, by the way that foam jet in underground work face, is adsorbed to dust, due to
The surface area of foam is big, adsorption of dust efficiency high, but passes in and out the shower nozzle sprayed all by the way of direct-injection to foam at present, its
Spray regime is limited, and sprays continuously, and for different environment, although there is various forms of shower nozzles, it is mainly used in flowing
Body, foam is being sprayed and not applied to, and due to the characteristic of foam, the pressure in injection can not be excessive；
Publication number CN204564373U discloses the foam dust suppression spray head of a kind of arc-shaped injection and angle adjustable, including spherical
Nozzle (1), famale connector (2) and male contact (4) ball nozzle (1) include the scarce spherosome with end face, and the end face for lacking spherosome is opened

Interior, the front end face of male contact (4) is acted against on the end face of scarce spherosome；Scarce spherosome front portion, which is provided with, communicates composition " V " with blind hole
Two bar-shaped troughs (7) of font bar shaped spout.The shower nozzle is oriented Jetting reduchng dust by the angle of adjusting shower nozzle to underground, but
Comprehensive injection can not be carried out simultaneously, and dustfall efficiency is low.
Publication number CN103240195A discloses a kind of foam dust suppression spray for preventing from coming off and arbitrarily adjusting spray angle
Head.Mainly it is made up of ball nozzle, famale connector, U-shaped card, male contact；Described ball nozzle includes the scarce spherosome with end face,
The end face for lacking spherosome is provided with blind hole, lacks spherosome front portion and is provided with the bar-shaped trough for being communicated with blind hole and forming bar shaped spout, spherical spray
Mouth is dynamic to be coordinated and is located in the anterior deep-slotted chip breaker of famale connector, 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, the central through hole communicated with bar shaped spout is provided with the middle part of male contact, is symmetrically provided with famale connector outer wall
The jack of lower connection, U-shaped card is fitted with jack, male contact, which corresponds to, is provided with annular groove at jack position.The injection of the shower nozzle
Be it is continuous directly, foam can not completely and underground dust progress Contact-sorption, reduce the dust-absorbing rate of foam.
The content of the invention
In order to improve the above situation, a kind of colliery construction underground intermittence foam dust suppression spray head of the present invention provides a kind of logical
Intermittent foam jet is crossed, foam and dust is fully contacted, improves the shower nozzle of dust-laying effect.
A kind of colliery construction underground intermittence foam dust suppression spray head of the present invention is realized in：The present invention applies in a kind of colliery
