Detailed description of the invention
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model mainly comprises water tank 9, and the water outlet of water tank 9 connects one end of water supply pipe 16, and water supply pipe 16 other ends connect coolant outlet pipe 8, and coolant outlet pipe 8 ends are provided with shower nozzle.When normal work, the water in water tank 9 enters shower nozzle by water supply pipe 16 and coolant outlet pipe 8 and sprays.Water supply pipe 16 is provided with high pressure pump 15, and high pressure pump 15 is squeezed into the water pressurization in water tank 1 in shower nozzle and sprayed, and water is not easy to remain in water pipe.
On coolant outlet pipe 8, connect the second return water pipe 13, the second return water pipes 13 by the second T-pipe joint 17 and connect vacuum pump 12, on vacuum pump 12, connect water tank 9 by the first return water pipe 11.Described the second return water pipe 13 is provided with the 3rd switch valve 14, the first return water pipes 11 and is provided with second switch valve 10.When fog system quits work, vacuum pump starts, and the 3rd switch valve is opened, and the water in coolant outlet pipe is withdrawn in water tank, until lack of water extracts to support vacuum pump in coolant outlet pipe, vacuum pump quits work, and remains in water in pipe by part sucking-off.
On coolant outlet pipe 8, connect the second tracheae 4, the second tracheaes 4 by the first T-pipe joint 7 and connect storage tank 3, storage tank 3 connects Air compressor 1 by the first tracheae 2.Described the second tracheae 4 is provided with the first switch valve 5.Air compressor 1 is by air compressing, and the air after compression is blown and beaten away the water remaining in coolant outlet pipe by shower nozzle, guarantees in coolant outlet pipe no longer residuary water.
