[0026] At the beginning, the fastening assembly 122 is opened, and the sealing side plate is rotated along the hinge axis to be on the same horizontal plane as the bottom plate of the flotation machine body, so that the cleaning vehicle can be pushed into the flotation machine body from the sealing side plate. The sealing side plate is rotated from a horizontal state to a vertical state, and is sealed with the outer wall of the flotation machine body. The sealing side plate is sealed by a sealing strip around the periphery to ensure that a sealed environment is formed in the flotation machine body.

[0027] A cleaning vehicle 2 loaded with quartz sand is provided in the flotation machine body, the cleaning vehicle comprises a cleaning box 202 and a plurality of groups of moving wheels 201, the cleaning box comprises a rectangular parallelepiped frame, each surface of the rectangular parallelepiped frame is provided with a filter screen 221, the mesh size of the filter screen is smaller than the diameter size of the quartz sand; the top surface of the cleaning box is provided with an open quartz sand loading and unloading port 205, an upper cover 204 is provided at the quartz sand loading and unloading port, one end of the upper cover is hinged to the edge of the quartz sand loading and unloading port through a hinge shaft, and an elastic buckle 206 is provided at the opposite end of the upper cover located at the hinge shaft.

[0028] Before the cleaning vehicle is pushed into the flotation machine body, the elastic buckle 206 is first opened, the upper cover is turned over to open the quartz sand loading and unloading port, and the quartz sand is loaded through the quartz sand loading and unloading port. When the quartz sand is loaded to 2 / 3 of the height in the cleaning box, the upper cover is closed on the quartz sand loading and unloading port, and the elastic buckle 206 is engaged. A handle 207 for transferring the cleaning vehicle is provided on the side wall of the cleaning box near the inlet and outlet. The cleaning vehicle is pushed by the handle and pushed into the flotation machine body along the sealing side plate rotated in the horizontal direction. An anti-collision strip 203 is provided between one side wall of the cleaning box and the inner wall of the flotation machine body on the corresponding side, so that the cleaning box will not cause collision and deformation to the inner wall of the flotation machine body.

[0029] A liquid inlet device 6 is provided on the top of the flotation machine body, and the liquid inlet device includes a row of four liquid inlet nozzles 602 arranged along the length direction of the flotation machine body, each liquid inlet nozzle is arranged facing the cleaning vehicle below, and the liquid inlet nozzles are all connected to a liquid inlet main pipe 601 outwardly, and a liquid inlet pump 611 and a liquid inlet valve 612 are provided in sequence upstream of the liquid inlet main pipe.

[0030] Initially, the liquid inlet valve and the liquid inlet pump are opened, and the pickling liquid flows into each liquid inlet nozzle 602 along the liquid inlet main pipe, and is sprayed out from the liquid inlet nozzle, and sprinkled onto the quartz sand along the filter screen of the cleaning box. The quartz sand is cleaned and washed layer by layer until the pickling liquid submerges the quartz sand, and the blasting of the pickling liquid is stopped.

[0031] On the other side of the flotation machine body, an ultrasonic device 1 is arranged facing the cleaning box, and the ultrasonic device includes a control box, a front panel is embedded in the control box body, and a control button 402 is arranged on the front panel.

[0034] The controller sends a signal, which is transmitted to the ultrasonic generator through the central processing unit. The ultrasonic generator generates high-frequency electrical energy, which is converted into mechanical vibration after the ultrasonic transducer receives the high-frequency electrical energy signal.

The quartz sand is cleaned and washed layer by layer until the water submerges the quartz sand, and the sandblasting water is stopped.

[0038] Turn on the control button and the ultrasonic device is powered on. The controller sends a signal, which is transmitted to the ultrasonic generator through the central processor. The ultrasonic generator generates high-frequency electrical energy, which is converted into mechanical vibration after the ultrasonic transducer receives the high-frequency electrical energy signal. The mechanical vibration generates high-frequency vibration with extremely small amplitude and propagates to the water in the cleaning tank. Under the action of the transducer, a large number of tiny bubbles will continue to be generated inside the water and burst instantly. The bursting of each bubble will generate a high temperature of hundreds of degrees and a shock wave of nearly one atmosphere of pressure, thereby vibrating the quartz sand to change its position and fully clean it, cleaning the quartz sand for the second time and cleaning the pickling liquid on the quartz sand.

[0039] Open the drainage pump 302 to discharge the waste water, open the fastening assembly 122, rotate the sealing side plate along the hinge axis to the same level as the bottom plate of the flotation machine body, pull the cleaning vehicle out of the sealing side plate 102 and push the flotation machine body out. After the quartz sand is cleaned, enter the drying process.
