Abstract
To overcome the defects that existing mine dust eliminating spraying devices are poor in spraying effect, high in cost and the like, the invention provides a mine dust eliminating spraying pipe. The mine dust eliminating spraying pipe comprises a spiral water pipe, wherein one end of the spiral water pipe is plugged, the periphery of the inner side of the spiral water pipe is provided with a plurality of water injection openings which are formed by drilling or cutting the inner side of the water pipe, and the water injection openings are round or crossed or shaped like a Chinese character 'mi'. The mine dust eliminating spraying pipe has the advantages that a simple pipe such as a copper pipe is bent into a spiral shape, the periphery of the inner side of the spiral water pipe is provided with the water injection openings, and therefore all-dimensional spraying dust elimination is achieved. To improve the dust eliminating effect, the water injection openings are improved to be round or crossed or shaped like the Chinese character 'mi'. Particularly, the eater injection openings shaped like the Chinese character 'mi' have optimal effects. The mine dust eliminating spraying pipe is simple in structure and convenient to manufacture; the straight copper pipe can be bent into a spiral shape after being provided with the water injection openings in batches, and production efficiency is improved.
Description
Technical field
The invention belongs to technology field, relate to the equipment in pre-mash gas extraction passage construction process before the formal exploitation of coal, be specifically related to mine dust that the extraction of a kind of coal mine gas dust the uses dirt sparge pipe that goes out.
Background technology
Coal mine gas, dust accident are one of disasters of down-hole, if there is gas, dust accident, not only can heavy damage production environment, and can cause casualties, cause huge loss to the people, enterprise, country, therefore, eliminating gas exceeding limit and dust is the precondition of prevention gas, dust accident, is also one of important leverage of mine safety production.
Yet, due to geologic sedimentation effect, a large amount of toxic and harmfuls such as gas in coal seam, have been overstock, in order to realize safe digging, generally, before digging, first to arrange special-purpose gas pumping tunnel, adopt underground drill rig construction extraction borehole to implement in advance gas pumping, after extraction is up to standard, can start digging coal.The Shi ore deposit underground work of gas pumping tunnel, working space is narrow, and rig is executed and is turned over journey and can produce a large amount of dust, the healthy formation serious harm to staff.In order to reduce this harm, the method for employing is to use a gathering-device dust to be removed by water spray by dust collection and in gathering-device at a brill mouthful place.Yet the water injector conventionally adopting is that common water pipeline can be at water spray-jet, and because existing water spraying direction is single, dirt poor effect causes going out.In order to reach the dirt effect of going out preferably, a large amount of fountain heads need to be set, improve the holistic cost of equipment.
Summary of the invention
The object of the invention is to go out in order to solve existing mine dust that dirt spray equipment spraying effect is not good and high in cost of production is not enough, proposed a kind of mine dust dirt sparge pipe that goes out.
Technical scheme of the present invention is: the mine dust dirt sparge pipe that goes out, it is characterized in that, the helical form water pipe that comprises single-ended shutoff, the inner side surrounding of described helical form water pipe is offered a plurality of water jets, water jet is by forming in insides of pipes boring or cutting, and water jet is shaped as circle or cross or M shape.
Further, above-mentioned helical form water pipe is copper pipe.
Further, one end of the not shutoff of described helical form water pipe comprises connector and rubber washer, for being connected with water source.
The invention has the beneficial effects as follows: the mine dust of the present invention dirt sparge pipe that goes out adopts simple pipeline such as copper pipe bends to helical form, by surrounding inside the spiral of spiral pipe, offers a plurality of water jets, realized the comprehensive water spray dirt that goes out.In order to improve the effect of the dirt that goes out, the present invention also provides the improvement project of water jet, such as circle hole shape, cross (gap) or M shape.Especially the outlet effect of M shape is better.And the solution of the present invention is simple in structure, for the ease of making, be bent into again helical form after can offering water jet in batches on straight copper tube, enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
The mine dust that the is illustrated in figure 1 the present embodiment dirt sparge pipe that goes out, the helical form water pipe 1 that comprises single-ended shutoff, the inner side surrounding of described helical form water pipe is offered a plurality of water jets 3, and water jet is by forming in insides of pipes boring or cutting, and water jet 3 is shaped as circle or cross or M shape.Because the easy brake forming of copper pipe and be difficult for being corroded, so above-mentioned helical form water pipe is preferably copper pipe in the present embodiment.Further, one end of the not shutoff of helical form water pipe comprises connector 2 and rubber washer, for being connected with water source.
The mine dust of the present embodiment dirt sparge pipe that goes out adopts simple pipeline such as copper pipe bends to helical form, by surrounding inside the spiral of spiral pipe, offers a plurality of water jets, has realized the comprehensive water spray dirt that goes out.In order to improve the effect of the dirt that goes out,
The present invention also provides the improvement project of water jet, such as circle hole shape, cross (gap) or M shape.Especially the outlet effect of M shape is better.And the solution of the present invention is simple in structure, for the ease of making, be bent into again helical form after can offering water jet in batches on straight copper tube, enhance productivity.For the hydraulic pressure of equalization of discharge mouth and the dirt effect of going out, by test, the distance between water jet is that 3-25cm effect is better.
Those of ordinary skill in the art will appreciate that, embodiment described here is in order to help reader understanding's principle of the present invention, should be understood to that protection scope of the present invention is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combinations that do not depart from essence of the present invention according to these technology enlightenments disclosed by the invention, and these distortion and combination are still in protection scope of the present invention.
Claims (4)
1. the mine dust dirt sparge pipe that goes out, it is characterized in that, comprise the helical form water pipe of single-ended shutoff, the inner side surrounding of described helical form water pipe is offered a plurality of water jets, water jet is by forming in insides of pipes boring or cutting, and water jet is shaped as circle or cross or M shape.
