Abstract
The utility model provides a nozzle which can generate flat face-shaped water mist, mainly for dust proof of the lower of a mine. The nozzle comprises a case, a turbo shaped water guiding core or a spiral shaped water guiding core, a nozzle opening, etc. The utility model is characterized in that the cross-sectional shape of an atomizing chamber changes from a circular to a rectangle, through different long-short axial ellipticals, the water mist is blowed out through the slit of a shaping stick and a nozzle opening so that flat face spray is realized by the supercharging single water action of a parallel screw water guiding core, and steel plates are compositely magnetized at outside end of a shaping chamber, further improving spraying effect. The nozzle has the advantages of convenient dismounting, good spraying effect and high dust allayment rate, which can be suitable for the comprehensive dust-proof need of different industries.
Description
The utility model relates to a kind of Spray-nozzle for removing dust that can produce plane water smoke, is mainly used in preventing dust under the coal mine.
At present, the sprayer (nozzle) of dustproof usefulness mainly contains hollow cone beam nozzle, solid circular cone beam nozzle from the spray shapes branch under the coal mine.Taper beam structure of nozzle mainly is made up of the shell that is threaded connection, turbine type or several parts such as spiral water guide core, circle hole shape jet hole.Its shortcoming is: because spraying is coniform, must arrange a plurality of nozzles at coal-winning machine, development machine, hydraulic support, air decontamination place, tunnel, and exist spraying uneven, leak spray, spraying is overlapping, water consumption big, system complex, the problem that influences spraying firing dust efficient such as difficult in maintenance.
The wind and water combined duckbilled sprayer that " coal dust Prevention Technique " book is introduced mainly is made up of housing, water supply connector, air intake joint, several parts of duckbill spout, need be equipped with compressed air plant and air line when its shortcoming is to use, and require hydraulic pressure must be lower than blast.The compressed air plant that present coal system uses generally the highest blast is 0.8mpa, deducts the pipe network linear loss, and blast has only 0.6mpa, and the water after staticizing, general fine pressure is 1mpa, and dynamic pressure is 1～5mpa, and therefore, the use of this sprayer is restricted.
The purpose of this utility model is exactly the problem at above-mentioned existence, provides a kind of single water effect, spraying to be plane Dust-proof nozzle.
For realizing above-mentioned task, the structure of Dust-proof nozzle is made up of housing, turbine type or spiral water guide core, jet hole substantially, and its special character is, connects an atomizing piece in the housing upper end, and the shape of cross section of spray chamber changes, and carries out the transition to flat rectangle by circle; Connect a flat dressing stick in atomizing piece upper end, the shape of its inner chamber conforms to it; Connect a more flat jet hole again on dressing stick top, its profile can consist of fan-shaped, semicircle, polygon or rectangle with dressing stick, and the inner chamber cross section of jet hole is a slit, and the slit gauge is 0.2～1.5 millimeter.
In order to improve atomizing effect, can be on the upper and lower plane of shaping chamber a compound magnetization steel plate.
Owing to take said structure, saved the compressed-air system in the wind and water combined duckbilled sprayer, enlarged the flat spray area; Simplified the flat spray system that multiinjector is formed; And owing to added the magnetization steel plate, make spraying evenly, conserve water.In coal-face dustproof, just can cover coal mining machine roller with one or two nozzle, utilize the characteristics of its plane beam, with the spraying water curtain with machine road and pavement isolation, minimizing unit driver and other personnel's vacuum cleaner meeting.
Following accompanying drawing has been described an embodiment of the present utility model:
Fig. 1 is a front view of the present utility model.
Fig. 2 is the cutaway view of A-A line among Fig. 1.
In the drawings, housing 6 is for having the column of a through hole, and the bottom water inlet end is push-in joint; Water guide core 5 is contained in housing inner chamber middle part, and the water guide core is a cylinder, and in the periphery milling 4 helical angles being arranged is 45 ° guiding gutter, and the cross section of guiding gutter is a rectangle, and the water guide core has single water pressurization; At housing upper end welding one atomizing piece 4, the shape of cross section of its inner chamber spray chamber 7 changes, and carries out the transition to the ellipse of different major and minor axis by the circle on water guide core top, carries out the transition to flat rectangle again; Welding one has the dressing stick 3 of flat inner chamber on the atomizing piece, and dressing stick is by two fan-shaped steel plate welding productions, is compounded with magnetization steel plate 2 on the above and below; Jet hole 1 also is by two block plate welding productions, and forming angle with dressing stick is 120 ° fan-shaped, and the jet hole inner chamber is 0.5 millimeter slit.
Claims (2)
1, a kind of Dust-proof nozzle, comprise housing 6, be contained in turbine type or spiral water guide core 5 in the housing, the jet hole that is connected with housing etc., its principal character is, housing 6 upper ends connect an atomizing piece 4, the shape of cross section of its spray chamber 7 changes, by circle excessively to the ellipse of different major and minor axis, after spending flat rectangle, connect a dressing stick 3 in the spray chamber upper end, being shaped as of dressing stick is flat, and has the flat inner chamber that communicates with the housing inner chamber, connect a jet hole 1 flat and that have the slit inner chamber at the dressing stick front end, its clearance distance is 0.2～1.5mm.
2, Dust-proof nozzle according to claim 1 is characterized in that, dressing stick and nozzle can mutual group become fan shape, can a compound magnetization steel plate 2 on the upper and lower plane of dressing stick.
