Embodiment Construction

[0021] Now in conjunction with accompanying drawing, the present invention is described in further detail.

[0022] Such as figure 1 , figure 2 and image 3 The cyclone water direct injection sand flushing device shown includes an outer pipe 6 and a central pipe 7, the outer pipe 6 is connected to a compressed air storage tank 8, the compressed air storage tank 8 provides pressure gas to enter the outer pipe 6, and the central pipe 7 is connected to a water tank 14 , the water tank 14 provides water or medicine to enter the central pipe 7; the outer pipe 6 and the central pipe 7 are jacketed structures, the front end of the central pipe is a liquid nozzle 3, and the liquid in the central pipe 7 enters the Rafal curved surface expansion chamber 4 from the back to the front The taper portion of the center pipe 7 is non-full contact coaxially embedded in the outer pipe 6, and the diversion section in the outer pipe 6 has a change process of shrinking and then enlarging. The f...

Abstract

The invention discloses a cyclonic-water and sand direct-jet type washing device. An outer pipe is connected with a compressed air storage tank. A center pipe is connected with a water tank. The outer pipe and the center pipe are of a jacket structure. A liquid spray opening is formed in the front end of the center pipe. Liquid in the center pipe enters a Laval curved face expansion chamber. The conic section of the center pipe is coaxially embedded into the outer pipe in a partial contact manner. The flow guide section in the outer pipe shrinks firstly and then becomes large. Compressed air flows in a conical-cylinder-shaped throttling channel between the outer pipe and the center pipe and enters the Laval curved face expansion chamber in a rotary jet manner through a spiral runner between a hydrocyclone and the center pipe. A gas and water mixture is delivered to a spray pipe in the front due to the Laval effect, an hourglass is connected to the position above the spray pipe, and a gas, water and sand mixture is evenly jetted out through a spray opening in the front of the spray pipe at a high speed. The cyclonic-water and sand direct-jet type washing device is simple in structure, reliable, ingenious, low in cost and capable of converting compressed air potential energy into jet flight power in a most effective manner, the gas, the water and the sand are very evenly mixed as well, and efficient and high-quality strong impact spray-washing operation with the ultra-low amount of water is achieved.

Description

technical field [0001] The invention relates to a flushing device, in particular to a cyclone water direct injection type flushing device with sand utilizing the working principle of a Lafal nozzle. Background technique [0002] Flushing is a frequently used method of operation. Flushing with high-pressure water is currently a more popular method. Its advantages are good flushing effect and high water pressure, but it also has the disadvantages of large water consumption and energy consumption, which does not meet the current advocacy in my country. energy saving and emission reduction policies. [0003] Therefore, we try to implement the optimal design of the air-water sand jet cleaning device by flexibly applying the working principle of the Rafal nozzle and combining the working principle that the rifle barrel is beneficial to increase the bullet exit velocity to carry out the cyclone water direct jetting. The air, water and sand with a small amount of water and a long ra...
