Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a cyclone water direct spray flushing device which skillfully applies the working principle of the Lafal nozzle to spray. This spray has the advantages of simple structure, low water consumption, The characteristics of high-speed uniformity after air-water mixing.

In order to overcome the deficiencies in the prior art, the present invention takes the following technical solutions:

A cyclone water direct injection flushing device, including an outer pipe and a central pipe, characterized in that the outer pipe is connected to a compressed air storage tank, the compressed air storage tank provides pressure gas to enter the outer pipe, the central pipe is connected to a water tank, and the water tank provides water or medicine Enter the central tube; the outer tube and the central tube are jacketed structures, the front end of the central tube is a liquid nozzle, and the liquid in the central tube enters the Rafal surface expansion chamber from the back to the front; the taper of the central tube is not in full contact and coaxially embedded in the outer tube , the diversion section inside the outer tube has a change process of shrinking and then enlarging. The compressed air flows forward in the conical cylindrical throttling channel between the outer tube and the central tube, and also enters the pull method through the spiral jet between the cyclone and the central tube. The Rafal surface expansion chamber, the Rafal curved surface expansion chamber is also the mixing chamber where the compressed air and the pressurized water swirl into. The nozzle shoots out at high speed.

A water valve, a filter and a pressurized water pump are arranged on the connecting pipe between the central pipe and the water tank.

An air valve is arranged on the pipe connecting the outer pipe and the compressed air storage tank.

The compressed air storage tank is connected with an air compressor, a safety valve, a pressure gauge and a bottom valve.

The present invention mainly uses the working principle of the Lafal nozzle flexibly, and combines the working principle that the rifle barrel is beneficial to improve the bullet exit velocity to optimize the design of the cyclone water direct spray flushing device, which can realize the most reasonable energy conversion, The water consumption is the lowest, and the air-water mixed jet is evenly sprayed at a high speed, and the rinse is thorough.

The working principle of the Rafal nozzle is as follows: for a nozzle with a throat, when the compressed gas first gradually enters the narrowest throat from the tube with a larger cross-section, the process follows the classic fluid mechanics, and the flow velocity increases when the cross-section becomes smaller. The resistance also increases sharply and rapidly, forming a gas throttling flow, but the compressed gas enters the expansion tube part whose cross-section gradually expands after passing through the smallest section of the throat. Due to the depressurization and expansion of the compressed gas, the gas no longer follows the classical fluid mechanics, but It can be ejected from the expansion tube at a very high speed. If the compressed gas pressure is high enough and the nozzle structure is reasonable, the gas can be ejected from the nozzle at supersonic speed. The working principle of the Rafal nozzle is applied to jet aircraft and rockets, which greatly improves the efficiency and power of the jet engine, and realizes the overflight of aerospace and aviation technology. Here, the characteristics of the Rafal effect are used to make the spraying range long, efficient and uniform , low water consumption.

The high-speed spraying of air-water mixing can realize the most reasonable conversion of energy, so that the compressed air energy can drive the air-water to mix evenly and spread the spray optimally, so that the spraying ingredients can be sprayed to the target. The longer nozzle is similar to a long-barreled rifle. It is especially beneficial that the potential energy of the compressed air is continuously improved and the air-water mixture is accelerated forward to realize high-speed and uniform injection from the nozzle.

Compared with prior art, the beneficial effect of the present invention also lies in:

The flow rate and injection speed can be reasonable by adjusting the pressure of compressed air and water delivery; the throttling characteristics of the gas-liquid flow channel can obtain the best mixing ratio required for the required gas-liquid swirl injection; the gas phase and the liquid phase enter together In the mixing chamber, due to the Rafal effect, the compressed air expands to drive the gas-water mixture and sprays out from the nozzle at high speed. The longer nozzle is similar to the long tube of a rifle, making the spray farther and the gas-liquid more uniform.

The device of the invention is simple in structure, reliable, ingenious and low in cost, can most effectively convert the potential energy of compressed air into jet flight power, and the gas-liquid mixing is also very uniform, and realizes high-efficiency, high-quality, ultra-low water impact spraying operation.
