Fig. 1 is the structural representation of a kind of embodiment of anti-freeze water delivery device provided by the utility model;
Fig. 2 is the principle schematic of the water delivery device of anti-freeze shown in Fig. 1;
Fig. 3 is the principle schematic of the spray dust-reducing system of use provided by the utility model water delivery device shown in Figure 1.
The specific embodiment
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of embodiment that uses the spray dust-reducing system of anti-freeze water delivery device, spray dust-reducing system among this embodiment comprises water delivery device, the delivery port of the end of the outlet pipe of water delivery device is connected with shower nozzle 20, water delivery device comprises storage tank 1 and the water inlet pipe 9 that is connected on the storage tank 1, overflow pipe 3, outlet pipe 6, wherein, the conducting when water level of overflow pipe 3 in storage tank 1 is too high is in order to lead away unnecessary water, the delivery port of overflow pipe 3 is connected on the outlet pipe 6, the delivery port of end for being used for being connected with the shower nozzle of spray dust-reducing system at outlet pipe 6, be serially connected with for the water pump of the storage tank high-pressure pump 5 to the shower nozzle in the spray dust-reducing system at outlet pipe 6, outlet pipe 6 herein is connected with air compressor machine 4 by appendix 14, be provided with for the water that prevents outlet pipe at appendix 14 and enter described air compressor machine, and the gases at high pressure of exporting in the assurance air compressor machine enter check valve 11 in the outlet pipe by appendix, on outlet pipe 6, be respectively arranged with the first switch valve 13 and second switch valve 12 for control outlet pipe break-make in the both sides of the outlet pipe pipeline section of corresponding appendix 14, herein the first switch valve 13 and second switch valve 12 are electrical ball valve, and high-pressure pump 5 is between the first switch valve and storage tank.Be connected with when air compressor machine work is opened to input high pressure gas and the first switch valve in the outlet pipe by appendix and the discharge pipe line 8 of conducting is serially connected with the electrical ball valve 7 for control discharge pipe line break-make on this discharge pipe line 8 at storage tank 1.
