Detailed Description
The utility model will be described in detail below with reference to the drawings and the detailed description.
When the current fully-mechanized coal mining machine is driven, dust is suspended in the air for a long time due to poor water source spraying effect, visibility is reduced, ventilation air methane is used for rushing to the whole roadway, and the phenomenon of dust emission and the like is easy to occur due to wellhead rushing. In the coal mine infrastructure project, dust prevention and control are the types of occupational disease hazard prevention and control, and are particularly important in the tunneling process of a tunneling machine, so that according to the actual condition of the site, the fixed full-face spray which is singly dependent on water pressure is modified into wind-water linkage spray, and the pressure is adjustable, so that the problems can be effectively solved.
The utility model discloses an adjustable full-section spraying device in a roadway, which is shown in fig. 1, and comprises a plurality of spraying hoses 20 arranged along the inner walls of different cross sections of the roadway, wherein a plurality of nozzles are arranged on the spraying hoses 20 at intervals. In the embodiment of the utility model, the original spray hard pipe is replaced by the spray hose 20, so that the spray hard pipe is convenient to install, and when the spray position needs to be adjusted, the spray hard pipe can be adjusted more conveniently and more conveniently according to the needs.
Regarding the problem of installing the nozzle on the spray hose 20, the spray hose 20 may be divided into a plurality of sections, a tee is installed between the two ends connected to each other, and a nozzle is installed at the third outlet of the tee.
The inlet end of the spray hose 20 is provided with a three-way joint 50; the first inlet of the three-way joint 50 is connected with the water source main pipe 30 (i.e. the three-way connecting pipe on the water source main pipe 30) through a branch pipe 60, and the second inlet of the three-way joint 50 is connected with the air source main pipe 40 (i.e. the three-way connecting pipe on the air source main pipe 30) through another branch pipe 60; wherein both the water source and the air source enter the spray hose 20 to increase the water source pressure during spraying.
According to the utility model, the pressure of spraying water mist can be effectively increased by mixing the gas source and the water source which are commonly used in the tunnel underground through the three-way connector 50 and then jointly entering the spraying hose 20, so that the dust removing effect is improved. The three-way connector 50 may be a quick connector for ease of installation.
In one embodiment, as shown in fig. 3, the first inlet/second inlet of the three-way joint is connected to the branch pipe 60 through a connection hose 70. The connection hose 70 can be conveniently connected with the air source main pipe 40/the water source main pipe 30 through the design of the branch pipe 60, because the branch pipe 60 adopts a hard pipe design, one end of the branch pipe is welded with the main pipe, and the connection hose 70 at the other end can be directly inserted on the outer wall of the branch pipe 60, so that the operation is convenient.
In addition, as shown in fig. 2, a plurality of fixing frames 80 are installed on the inner wall of the roadway 10 at intervals, and the spray hose 20 is fixed on the plurality of fixing frames 80. Since the spray hose 20 is a hose and cannot be directly welded and fixed like a common steel pipe, the fixing frame 80 is installed on the inner wall of the roadway, and the spray hose 20 can be bound on the fixing frame 80. The shape of the fixing frame 80 can be designed according to the actual requirements of the site.
In one embodiment, each of the manifold 60 has an adjustment valve mounted thereon for adjusting the amount of air and water entering the spray hose 20. An outlet valve is mounted on the outlet of the three-way fitting 50. The valves installed on the branch pipes 60 are used for controlling the inlet amount of the water source and the air source, namely the proportion of the water source and the air source is regulated, and the outlet valve is used for regulating the size of the sprayed water mist and can be regulated according to the requirement.
According to the adjustable full-section spraying device, the adjustable valve is additionally arranged according to the principle of compressed air pressurization, so that water flow sprayed out of the nozzle is fully atomized, the spraying effect can be adjusted at any time according to the dust condition of a roadway, and the high-efficiency and saving effects are achieved. In addition, the traditional spray is poor in spray forming, cannot be adjusted, has more water yield, is easy to form accumulated water after long-time use of the pavement, causes excessive accumulated water in roadway sludge, not only affects civilized production, but also causes inconvenience to normal pedestrian driving.
The full-section spraying device adopts hoses to be paved along the section of a roadway, 10 nozzles are adopted, 1 electric welder is used for processing, and 4 working stations can be used for processing. The explosion-proof loader is matched with the human body for 4 persons during installation.
The adjustable full-section spraying device provided by the embodiment of the utility model has the advantages that the flexible pipe is utilized for processing, the fixation is reliable, the installation is convenient, the use is convenient, the installation is completed only by 10 minutes, the service life is long, and the installation position can be adjusted according to the requirement in the later stage.
In addition, the water quantity can be saved after the air source and the water source are combined. The water consumption of the original spraying per hour is 1.45m 3, the maximum water consumption of the adjustable spraying is 1.1m 3, the minimum mist forming water consumption is 0.35m 3, the water consumption of normal tunneling dust is 0.8m 3, the spraying device 12 channels are needed in the main inclined shaft tunnel, water consumption (1.45-0.8) multiplied by 12=7.8m 3 can be saved per hour, the tunneling of a normal comprehensive tunneling machine can be carried out for 16 hours every day, the water consumption of 7.8x16=124.8m 3 can be saved every day, the water consumption cost of 3744m 3 can be saved every month, and the economic effect is obvious.
In summary, the full-section spraying device has the advantages of low processing cost, convenient use, convenient installation and obvious effect; the spraying quantity can be adjusted according to the dust quantity in the tunnel air, so that targeted dust removal and dust removal can be performed; the device has the advantages of large water pressure, wide coverage, good fog dispersion effect, capability of atomizing and adsorbing dust, and good condition for underground comprehensive dust prevention; compared with the traditional spray, the spray has the advantages of saving water consumption, high internal pressure, difficult blockage of the spray nozzle, and long-term economic value from economic and practical analysis.
