Abstract
A foam generator for underground dust removal comprises a column casing, and a conical cylinder connected with the column casing into a whole. A foaming screen is arranged at the connection opening of the column casing and the conical cylinder; an air inlet hole is formed on the column casing, and a liquid inlet pipe is arranged at the bottom part; a spiral spray nozzle is mounted on an extension pipe of the liquid inlet pipe; and a foam outlet is formed at the front end of the conical cylinder. The spiral spray nozzle adopted on the generator sprinkles a liquid on the foaming screen in the shape of a conical surface by changing the flow direction therein; because the flowing sectional area is large, the phenomenon of the spray nozzle blocked by impurities in water is avoided; the material of the foaming screen adopts stainless steel, and the structure thereof adopts a complex formed by combining a hollow cone with an arc surface, thereby avoiding the disadvantage that the foaming screen is easy to damage, and also being more favorable for the film forming and the foaming of the foaming liquid. The foam generator has the advantages of simple structure, small volume, light weight, difficult spray nozzle jam, high firm forming ratio of the foaming liquid and good forming effect, and is very suitable for working conditions of the underground water quality and the narrow space in a coal mine.
Description
Technical field
The utility model relates to a kind of foam maker, particularly a kind ofly is used for the foam maker that foam dust-removing is used under the coal mine.
Background technology
The per pass operation of coal mine operation all produces with a large amount of dust, and workman's operation in this environment will suck a large amount of dust, serious harm workman's physical and mental health.Present about 260,000 people of pneumoconiosis patient of China's coal-mine industry, and with annual 5000 people's speed increase, annual nearly 3000 people die from pneumoconiosis, have brought great misery for patient and family thereof, have also caused enormous economic loss to country.Be the effectively preventing Mine Dust, the foam dust-removing that just begins one's study of external the seventies, the key technology of foam dust-removing is exactly a foam maker.The two-phase frostproof froth n device of widespread usage mainly is a network structure at present, mainly is made of shell, nozzle and a foam screen.Foam theory is that nozzle is sprayed onto the foaming liquid atomizing on the foam screen, forms liquid film on the net, and compressed air is advertised liquid film and foamed.This foam maker is applied to exist under the coal mine two shortcomings: the one, and the pulverizing nozzle diameter is too little, owing to often contain impurity in the mine water, causes spray nozzle clogging easily; The 2nd, to send out foam screen and adopt materials such as nylon or linen-cotton to be made usually, these materials are damaged easily, need often to change.Even the foam screen of sending out that steel plate makes had appearred in fire protection sector afterwards, but because foaming is used under the coal mine is compressed air, stream pressure and speed is all a lot of greatly than the employed air of fire protection sector.So the structure and the shape of these nets are not suitable for underground mine use, also are unfavorable for expanding foam solution film forming on the net, thereby cause foaming effect bad.Need the nozzle of the type foam maker and the material and the structure of a foam screen are improved for this reason.
The utility model content
The purpose of this utility model is the deficiency that overcomes in the prior art, and a kind of compact conformation is provided, the foam maker of the dust removing down-hole that volume is little, be difficult for stopping up, foaming effect is good.
For achieving the above object, the foam maker of dust removing down-hole of the present utility model comprises column casing, with the awl tube that column casing is connected as one, column casing is provided with foam screen with awl tube connecting port place, and column casing is provided with air inlet, the bottom is provided with feed tube, on the prolongation pipe of feed tube spiral nozzle is housed; The front end of awl tube is provided with foam outlet.
The rear portion of described foam screen is a taper seat, and the front portion that is interlocked with taper seat is an arc surface, is drilled with some apertures on taper seat and the arc surface; Have helicla flute on the described spiral nozzle; Described spiral nozzle is made with copper material.
The utility model changes the inner original atomizer of foam maker into spiral nozzle, owing on the spiral nozzle helicla flute is arranged, by the spiral fluted effect, has changed the direction of current, and has produced tangential velocity.Because current flow in shower nozzle, its direction is followed the change of helicla flute direction and is changed, because effect of inertia, current still move along the direction that exports moment when outlet, finally causes current to become the ejection of open circles taper; Next has changed structure, shape and the material of foam screen, and the taper seat of latter half just in time coincide with the open circles taper current of spiral nozzle ejection, and foam mixing liquid is sprayed at by shower nozzle and sends out that the foam screen surface is easier to form uniform film.The VELOCITY DISTRIBUTION of the arc-shaped surface of first half and the distinguished and admirable motion of pipe interior is consistent, and more helps the foam solution foaming.The space that material passes through is big, can not stop up.It is simple in structure, volume is little, in light weight, shower nozzle is difficult for stopping up, expanding foam solution rate of film build height, and foaming effect is good, is fit to very much the narrow and small condition of work of water quality and space under the coal mine.
Description of drawings
Accompanying drawing is a structure sectional view of the present utility model.
Among the figure: feed tube-1, air inlet-2, spiral nozzle-3, foam screen-4, foam outlet-5, awl tube-6, bolt-7, stop screw-8, column casing-9.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Shown in the accompanying drawing, the shell of foam maker is made of column casing 9 and awl tube 6, and column casing 9 and awl tube 6 are in the same place by flange and Bolt Connection, can dismantle flexibly, make things convenient for the foam maker internal overhaul.Column casing 9 is equipped with foam screen 4 with awl tube 6 connecting port places, and fixing by screw 8, the rear portion of foam screen 4 is a taper seat, the front portion that is interlocked with taper seat is an arc surface, be drilled with some apertures on taper seat and the arc surface, the diameter in hole is 2～3mm, and material adopts the thick stainless steel of 2mm to manufacture.Column casing 9 is provided with air inlet 2, and the bottom is provided with feed tube 1, on the prolongation pipe of feed tube 1 spiral nozzle 3 is housed, and has helicla flute on the spiral nozzle 3, spiral fluted wide and dark be 8mm; The front end of awl tube 6 is provided with foam outlet 5.
During work, foam mixing liquid enters foam maker from feed tube 1, being the open circles taper by spiral nozzle 3 is sprayed to it on taper seat of foam screen 4, foam solution forms liquid film on foam screen, compressed air enters foam maker from air inlet 2 and advertises liquid film on the foam screen, produces a large amount of foams and discharges from foam outlet 5.
