Abstract
The utility model relates to a high-pressure mist-spraying frame of underworkings. The high-pressure mist-spraying frame comprises a transverse frame body arranged at the top part of the underworkings, wherein the frame body is provided with multiple nozzles; the spraying directions of the nozzles located at two ends of the frame body are respectively inclined for an alpha angle towards two sides of a roadway; the spraying directions of nozzles located in the middle of the frame body includes a downwards-spraying direction and a spraying direction having a beta angle with a windward direction and the horizontal plane; and nozzles with the two spraying directions are arranged at intervals. The high-pressure mist-spraying frame of the underworkings, disclosed by the utility model, has the advantages of efficiently reducing a watering blind region efficiently and thereby guaranteeing dust falling effects of the underworkings through the setting of the direction of the nozzles.
Description
Technical field
The utility model belongs to the mining equipment technical field, relates to a kind of device for reducing dust, especially a kind of underworkings high-pressure fog frame.
Background technology
China is big coal country, and output of coal leaps to world front three, because most of coal all is stored in the underground; So must exploit with the form of mine, and underground work is breakneck that a lot of coal mining accidents all can take place every year in China for coal workman's personal safety; And all can pay the cost of blood each time, in these coal mining accidents, more common is exactly that down-hole toxic gas or coal powder density are too high; Especially the too high meeting of dust directly influences downhole safety; And cause blast easily, therefore, need a kind of device that can effectively get rid of the down-hole coal dust.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of underworkings high-pressure fog frame is provided, and this nozzle can be accomplished the secondary-atomizing process to water smoke, improves atomization quality.
The purpose of the utility model solves through following technical scheme:
This underworkings high-pressure fog frame; Comprise the horizontal support body that is arranged on the underworkings top; On said support body, plurality of nozzles is installed; The injection direction of nozzle that is positioned at the support body two ends is to tilt alpha angle respectively, both sides, tunnel, the injection direction that is positioned at the nozzle at support body middle part be divided into under spray and be the injection of β angle to windward set direction and level, and the nozzle of two kinds of injection directions is provided with at interval.
Above-mentioned α is 45 °.Above-mentioned β is 15 °.Said support body is the water pipe support body, nozzle directly with cross current as support body.
The underworkings high-pressure fog frame of the utility model through be provided with nozzle towards, can effectively dwindle the watering blind area, thereby guarantee the dust-laying effect of underworkings.
Description of drawings
Fig. 1 is the cut-away illustration of the utility model;
Fig. 2 is the vertical view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1 and Fig. 2; The underworkings high-pressure fog frame of the utility model; Comprise the horizontal support body 1 that is arranged on underworkings 4 tops, plurality of nozzles 2 is installed on support body 1, the injection direction that is positioned at the nozzle 2 at support body 1 two ends is distinguished the tilt alpha angle to the both sides, tunnel; The injection direction that is positioned at the nozzle 2 at support body 1 middle part be divided into under spray and be the β angle and spray, and nozzle 2 settings at interval of two kinds of injection directions to windward set direction and level.In the preferred plan of the utility model, the α angle is chosen as 45 °, and the β angle is chosen as 15 °.And support body 1 is the water pipe support body, nozzle directly with cross current as support body.
The spraying frame operating principle of the utility model is following:
1. the nozzle spray direction at spraying frame two ends tilts 45 ° to tunnel group, and the I district is dwindled greatly.
2. nozzle number suitably increases, to reduce II district area.
3. if 6 nozzles are arranged, then 3 nozzles are sprayed downwards, and other 3 nozzles are 15 ° of angle directions injections to windward set direction and level, dwindle space, II district.
4. water pressure should reach 10～15MPa, and the blind area does not almost have under distinguished and admirable effect.As shown in Figure 2.
Claims (4)
1. underworkings high-pressure fog frame; It is characterized in that; Comprise the horizontal support body (1) that is arranged on underworkings (4) top, plurality of nozzles (2) is installed on said support body (1), the injection direction that is positioned at the nozzle (2) at support body (1) two ends is distinguished the tilt alpha angle to the both sides, tunnel; The injection direction that is positioned at the nozzle (2) at support body (1) middle part be divided into under spray and be the β angle and spray, and the nozzle of two kinds of injection directions (2) setting at interval to windward set direction and level.
2. underworkings high-pressure fog frame according to claim 1 is characterized in that said α is 45 °.
3. underworkings high-pressure fog frame according to claim 1 is characterized in that said β is 15 °.
4. underworkings high-pressure fog frame according to claim 1 is characterized in that said support body (1) is the water pipe support body, nozzle directly with cross current as support body.
