Description

[Detailed explanation of the invention] A. Purpose of the invention When the nozzle of this invention is generating fine mist, a high pressure of 10 to 17 kg/cm ² is normally applied to the piping, so when the pump operation is stopped, the residual pressure will cause the nozzle to The purpose is to prevent liquid from dripping and to clean the inside of the nozzle and piping.

B. Structure of the invention To explain this invention with reference to an illustrative diagram, the collision plate 1'
A socket A with a cap A' for supporting the jet pipe 1 in which a hard metal square tip 2' is fitted into the jet port 2 opposite to the socket A.
The socket A is fitted to the required water supply pipe B at arbitrary intervals, and the end of the pipe B is equipped with a drain valve 3, and the starting end of the pipe B is connected to a fresh water tank 4 and a chemical solution. This configuration includes a pressure pump 6 connected to the tank 5, and a pressure relief solenoid valve 7 at an arbitrary position on the piping B. In some cases, a solenoid valve may be used as the drain valve.

C. Effects of the invention Since the present invention is configured as described above, by operating the pressure relief solenoid valve 7 when the pump 6 stops operating, the pressure in the pipe B is released, so that the nozzle that is generating fine mist is removed. The liquid will not drip from the nozzle at the same time as the injection stops. In addition, the pump 6 is equipped with a chemical tank 5 and a fresh water tank 4, so after injecting the chemical liquid, switch to fresh water and open the liquid drain valve 3 to send fresh water, the chemical liquid in the pipe will be discharged from the liquid drain valve and the inside of the pipe will be cleaned. be done. After that, when the drain valve is closed, pressure is applied to the nozzle and fresh water is sprayed, allowing the nozzle to be cleaned.

As described above, the device of the present invention can prevent liquid from dripping from the nozzle, reduce the amount of chemical liquid used, and extend the life of the nozzle by automatically cleaning the nozzle. In addition, the jet pipe 1 is supported by being fitted into the socket A with the cap A', and is attached to the pipe B via the socket A, so that it can be easily replaced if the jet pipe 1 is damaged, etc., for various practical reasons. This is an effective idea.
