Abstract

The utility model discloses a de-dust sprayer, for effectively removing dust of high-density coal dust, in under mine working. The utility model is composed of a nozzle, a spray tube, a sealing bar, a fixing support and a fixing groove. The fixing support is in the fixing groove, the spray tube has an axial cut, the spray tube is mounted in a hole of the fixing support, the upper two ends of the nozzle are respectively arranged with a rivet structure, at least one nozzle via a rivet structure is serially connected integrally, the nozzles are arranged with sealing pads between, the lower two sides of the nozzle are respectively arranged with a groove, an embed groove with an elastic sealing bar is embedded in the cut of the spring tube, the center of the nozzle is provided with a spray hole, and one end of the spray tube is arranged with a seal plug. The utility model serially connects a plurality of nozzles integrally to be connected with the spray tube, to form an injector in any length according to on-site need, to spray water from multiple nozzles, to form a water curtain, with better de-dust effect.

Description

A kind of dust removal showerhead

Technical field

The utility model relates to a kind of mining water spray dust arrester.

Background technology

Produce a large amount of coal dusts during the work of coal mine fully-mechanized mining unit, the severe contamination mining face under mine, the harm workman's is healthy, even causes coal-dust explosion.At present, the employed dust arrester of down-hole fully-mechanized mining working coal mining unit is many based on Sprayable, and adopts the single-nozzle of limited quantity, because the particulate of water smoke is less, energy is little, and nozzle quantity is limited in addition, and it is unsatisfactory to carry out dust removing effects under high concentration coal dust condition.

Summary of the invention

The purpose of this utility model provides a kind of when being mainly used in coal mine operation, the dust removal showerhead that can carry out effective dedusting to the high concentration coal dust.

The utility model is achieved through the following technical solutions, it is made up of nozzle, jet pipe, sealing strip, fixed mount and holddown groove, fixed mount is arranged in holddown groove, one axial cut-outs is arranged on the jet pipe, jet pipe is installed in the hole of fixed mount, the nozzle both upper ends thereof has tenon riveting structure respectively, more than one nozzle is one by tenon riveting structure serial connection, be provided with sealing gasket between the nozzle, respectively there is a groove both sides, nozzle bottom, the groove that elastic sealing strip is housed is embedded in the jet pipe otch, and there is hole for water spraying at the jet pipe center, and jet pipe one end is provided with sealing-plug.

Because the utility model adopts a plurality of nozzle serial connections to be connected with jet pipe for one, can form the shower nozzle with random length according to the needs at scene, a plurality of nozzles are sprayed water simultaneously, form water curtain one, and dust removing effects is preferable.

The specific embodiment

Below in conjunction with drawings and embodiments the utility model is described in further detail.Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, nozzle of the present utility model (2) both upper ends thereof has the tenon riveting structure of concave, convex shape respectively, and respectively there is a groove nozzle (2) both sides, bottom, and there is hole for water spraying at jet pipe (4) center.Fig. 1, shown in Figure 2, a plurality of nozzles (2) for one, can be linked to be random length by tenon riveting structure serial connection, and the junction is equipped with sealing gasket between the nozzle (2), the groove that elastic sealing strip (1) is housed is embedded in jet pipe (4) otch, and jet pipe (4) one ends are provided with sealing-plug.Fixed mount (3) and holddown groove (5) are welded as a whole, and a circular hole that adapts with jet pipe (4) external diameter size is arranged in the middle of the fixed mount (3), and the jet pipe (4) that a plurality of nozzles (2) are housed penetrates in the circular hole in the fixed mount (3), makes nozzle (2) outside.

The nozzle of another embodiment of the utility model (2) as shown in Figure 8.When needing the dedusting environment of circle or circular arc, at this moment jet pipe (4) circumflexion or circular arc can be made the groove of nozzle (2) both sides, bottom and corresponding circle of jet pipe (4) otch or circular arc in some place.A plurality of nozzles (2) serial connection back embeds in the otch of circle or circular arc jet pipe (4), makes a plurality of nozzles (2) combination back form circle or circular arc, and other structure is identical with last embodiment with installation.

After above-mentioned connection, water pipe is inserted the end that jet pipe (4) does not have sealing-plug, open water valve, water sprays from nozzle (2) and forms one water curtain, reaches desirable dust removing effects.

Claims

1. dust removal showerhead, it is characterized in that: it is by nozzle (2), jet pipe (4), sealing strip (1), fixed mount (3) and holddown groove (5) are formed, fixed mount (3) is arranged in holddown groove (5), jet pipe has an axial cut-outs on (4), jet pipe (4) is installed in the hole of fixed mount (3), nozzle (2) both upper ends thereof has tenon riveting structure respectively, more than one nozzle (2) is one by tenon riveting structure serial connection, nozzle is provided with sealing gasket between (2), respectively there is a groove nozzle (2) both sides, bottom, the groove that elastic sealing strip (1) is housed is embedded in jet pipe (4) otch, and there is hole for water spraying at jet pipe (4) center, and jet pipe (4) one ends are provided with sealing-plug.
