Background technology
Mine dust is one of the main occupational hazards and natural calamity that coal production faces, and digging operation is the master operation of producing dirt, and its dust-producing amount accounts for more than 80% of total dust, the physical and mental health of serious harm coal miner and the safety in production of mine.Pneumoconiosis Patients about 320,000 people of current China's coal-mine industry, and with the speed increase of annual 5000 people, nearly 3000 people die from pneumoconiosis every year, bring great misery to patient and family thereof.In addition, the colliery of China more than 80% belongs to the mine that exploitation has coal seam liable to dust explosion, and wherein more than 50% has intense explosion, and since 2000, the whole nation is accumulative, and particularly serious dust explosion accident 10 occurs, and causes 815 people's death and over ten billion economic losses.In order to prevent and treat dust, underground coal mine generally adopts the technical measures such as spray for dust suppression and coal-bed flooding, but all could not well prevent and treat dust disaster because efficiency of dust collection is low.
Foam dust suppression technology is a kind of dust prevention and control technology that new development is got up, and has water consumption few, efficiency of dust collection advantages of higher, especially has significant dust-laying effect to respirable dust.The key of foam dust suppression technology is how foam is better sprayed on product dirt pits, as development machine pick place, transfer point, makes the solid that formation of foam one is closely knit, surrounds dust within the specific limits, make it not to external diffusion, reach the object of depositing dust.Shower nozzle is used widely at the other field such as agricultural production, spray for dust suppression.For different applied environments, have developed the shower nozzle of various different structure.That generally applies at present has mechanical type shower nozzle, Y type shower nozzle, rotating sprinkler, screw sprayhead and combined jet first-class several.The object of these shower nozzles application all makes the liquid atomization, be only only applicable to monophasic fluid, and inapplicable for two-phase or multiphase fluid of foaminess.Patent ZL200820040749.9, discloses a kind of foam nozzle being applicable to colliery foam dust suppression, and internal cavity and the end closure of this shower nozzle intersect vertically, foam stream is easily caused to be undergone mutation at cavity, clash into end closure, affect the stability of foam, thus affect its dust-laying effect.Patent ZL201120270768.2 also discloses a kind of foam dust suppression spray head, and its internal cavity has carried out round and smooth process, avoids the shock of foam stream, improves to some extent for maintenance foam stability aspect.But above-mentioned two kinds of shower nozzles exist the common drawback of three aspects: the first, the fan-shaped foam stream of these two kinds of shower nozzle ejections is in uneven thickness, easily occurs the thick intermediate thin in both sides, affects the covering of foam to dirt source; The second, these two kinds of shower nozzles are mainly connected with jet nozzle by screw thread, and in use, because shower nozzle is subject to the impact of the coal petrography that development machine cuts away, screw thread easily loosens, and shower nozzle easily comes off and loses; 3rd, the setting angle of shower nozzle directly affects dustfall efficiency, and because these two kinds of shower nozzles are screwed connections, during installation, shower nozzle direction is changeless, can not as required at any time any direction regulate nozzle angle, thus affect dust-laying effect.
Summary of the invention
Technical problem: the object of the invention is to overcome weak point of the prior art, the foam dust suppression spray head of the adjustable spray angle of slip-off preventing providing a kind of structure simple, effective.
Technical scheme: the foam dust suppression spray head of the adjustable spray angle of slip-off preventing of the present invention, is formed primarily of ball nozzle, famale connector, U-shaped card, male contact; Described ball nozzle comprises the scarce spherosome of band end face, the end face lacking spherosome has blind hole, lack spherosome front portion to have to communicate with blind hole and form the bar-shaped trough of bar shaped spout, ball nozzle moves to coordinate and is located in the deep-slotted chip breaker of famale connector front portion, male contact is sleeved in famale connector, the front end face of male contact leans on the end face of scarce spherosome, the central through hole communicated with bar shaped spout is had in the middle part of male contact, on described famale connector outer wall, symmetry has the jack be communicated with up and down, be fitted with U-shaped card in jack, the corresponding jack position place of male contact has annular groove.
Described male contact and famale connector threaded engagement; The outer surface front portion of described famale connector is the face of cylinder, and rear portion is for ease of six prismatic surfaces of dismounting.
Beneficial effect: the present invention passes through famale connector, male contact and ball nozzle closely cooperate, ball nozzle can rotate in the deep-slotted chip breaker of famale connector, the step that male contact is inner corresponding with famale connector matches, male contact annular slot is corresponding with the U-shaped hole clipping on famale connector surface, U-shaped card is famale connector, male contact close fit together, famale connector, male contact is connected with the dual cooperation of U-shaped card by screw thread, namely at famale connector, the tangent line of male contact and axis direction are all restricted to be loosened and the active force come off, therefore the drawback that shower nozzle comes off because screw thread easily loosens fundamentally is prevented.This nozzle structure is simple, outer surface is adopted to be that spherical bar shaped spout instead of original flat nozzle, make the depth of foam of ejection even, sectorial area is large, the angle of ball nozzle can be regulated arbitrarily as required, and difficult drop-off, be widely used in coal mine downhole foam depositing dust, also may be used for other field, as fire-fighting fire extinguishing etc.

Detailed description of the invention
Below in conjunction with accompanying drawing, one embodiment of the present of invention are further described:
The foam dust suppression spray head of the adjustable spray angle of slip-off preventing of the present invention, is formed primarily of ball nozzle 1, famale connector 2, U-shaped card 3, male contact 4; Described ball nozzle 1 comprises the scarce spherosome of band end face, the end face lacking spherosome has blind hole, lack spherosome front portion to have to communicate with blind hole and form the bar-shaped trough 7 of bar shaped spout, ball nozzle 1 is located in the deep-slotted chip breaker of famale connector 2 front portion, coordinate with the deep-slotted chip breaker of famale connector 2 front portion is dynamic, can make circumference and rotate in deep-slotted chip breaker, male contact 4 is sleeved in famale connector 2, the outer surface front portion of described famale connector 2 is the face of cylinder, and rear portion is for ease of six prismatic surfaces of dismounting.The front portion of described male contact 4 is processed with external screw thread, and the front portion of famale connector 2 is processed with the internal thread matched with the front external thread of male contact 4, male contact 4 and famale connector 2 threaded engagement.The front end face of male contact 4 leans on the end face of scarce spherosome, the central through hole 8 communicated with bar shaped spout is had in the middle part of male contact 4, on described famale connector 2 outer wall, symmetry has the jack 5 be communicated with up and down, be fitted with a small handdrum with beads striking when rotated male contact 4 and famale connector 2 in jack 5 to be fixed together U-shaped card 3, male contact 4 corresponding jack 5 position has annular groove 6, is provided with the O RunddichtringO of Leakage prevention between male contact 4 and famale connector 2.
In use procedure, male contact 4 is welded on head cartridge, and it is covering of the fan ejection that foam flows into central through hole 8 through the bar shaped spout of ball nozzle 1 from head cartridge.U-shaped card 3 plays the effect of two aspects, is that the internal and external threads preventing from having tightened loosens and causes the axially-movable of ball nozzle 1 on the one hand, carries out axial limiting to famale connector 2 and male contact 4.Namely when male contact 4 and famale connector 2 screwed tight, align with the step in famale connector 2 and jack 5 respectively with the seal groove of O-ring seals and annular groove 6, U-shaped card 3 is passed from jack 5, famale connector, male contact just can not produce motion in the axial direction, and the external screw thread tightened and internal thread also would not loosen.On the other hand, utilize U-shaped card 3 famale connector 2 and male contact 4 more firmly can be connected as a single entity, stopped the two and be subject to the impact that coal petrography that development machine cuts away collides, extrudes, falls to pounding and vibrate, shower nozzle easily comes off and loses.This shower nozzle can prevent from coming off because screw thread loosens in use procedure, and can regulate the angle direction of strip shape gob as required, effectively can cover underground coal mine dust source and suppress the diffusion of dust.And the fan-shaped depth of foam sprayed is evenly distributed, the foam nozzle that dustfall efficiency is high.
