[0002] Chinese patent document CN220215290U discloses a flotation coal preparation defoaming device, which generates negative pressure at the bottom of the guide cover by driving a crushing impeller to rotate through a driving motor, so that the foam enters the guide cover through the bottom of the guide cover, and the foam is torn into pieces by the shear force provided by the high-speed rotating crushing impeller. The liquid released by the foam is immediately thrown into the guide cover by centrifugal force and discharged through the through holes on the guide cover. Some of the foam will be broken and converted into liquid due to impact on the inner wall of the guide cover, and return to the liquid in the flotation tank, thereby reducing the loss of escaped liquid and ensuring the crushing effect. The equipment can be used repeatedly, with low cost and good effect, and will not cause pollution to the liquid, and is highly practical.

[0021] Furthermore, the free end of the electric push rod 3 extends below the support plate 2 and is fixedly installed with an extrusion plate 4, and a sliding rod 6 is fixedly installed at the bottom of the extrusion plate 4. This arrangement can move the extrusion plate 4 to the inside of the flotation box 5, so that the inside of the flotation box 5 can be pressurized, and the pressure difference is used to eliminate the bubbles generated during coal selection inside the flotation box 5, thereby improving the defoaming effect of the device.

[0022] Furthermore, a mounting tube 7 is fixedly installed on the top of the lifting plate 15, and a driving motor 10 is fixedly installed on the top of the lifting plate 15. The driving motor 10 is located inside the mounting tube 7. A rotating shaft 11 is rotatably installed on the bottom of the lifting plate 15. A fixing block 12 is fixedly installed on the outer wall of the rotating shaft 11. The rotating shaft of the driving motor 10 extends to the bottom of the lifting plate 15 and is fixedly installed with one end of the rotating shaft 11. A connecting plate 13 is fixedly installed on one side of the fixing block 12, and a movable baffle 14 is fixedly installed on one side of the connecting plate 13. This arrangement can take out the coal inside the flotation box 5 after defoaming the coal. This method of taking coal is relatively fast and can also avoid the steps of subsequent workers taking coal. It can not only reduce the workers' working time and intensity, but also improve the overall efficiency of coal washing processing and increase the practicality of the device.

[0023] Furthermore, the top of the movable baffle 14 is in contact with the bottom of the lifting plate 15 and is not fixed, the outer wall of the lifting plate 15 is in contact with the inner wall of the flotation box 5 and is not fixed, an opening is opened on one side of the flotation box 5, a partition plate 9 is fixedly installed on the inner wall of the mounting cylinder 7, and the partition plate 9 is located above the driving motor 10, and a sewage pipe is fixedly installed on the rear side of the flotation box 5, one end of the sewage pipe extends to the interior of the flotation box 5 and a stop valve is provided on the sewage pipe.

[0024] Working principle: When in use, pour the coal into the flotation box 5. After adding the coal selection liquid into the flotation box 5, stir the coal through a manual stirring device. During stirring, the heavier coal will fall to the bottom of the flotation box 5, and the lighter coal will float. Then, the electric push rod 3 is controlled to start and drive the squeezing plate 4 to descend. When the squeezing plate 4 descends, the air inside the flotation box 5 will be squeezed, thereby increasing the pressure and removing the bubbles generated during the stirring of the coal. After the bubbles are removed, the squeezing plate 4 is controlled to rise. The rising of the squeezing plate 4 drives the sliding rod 6 and the limiting circular plate 8 to move. The movement of the limiting circular plate 8 drives the installation cylinder 7 and the lifting plate 15 to move. The lifting plate 1 5 moves, the liquid can be moved. When the liquid moves, the floating coal on the liquid can be lifted up first. When the floating coal moves to the opening on the flotation box 5, the coal flows out through the opening together with the liquid. After flowing out, the driving motor 10 is controlled to start. The driving motor 10 starts to drive the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the fixed block 12 and the connecting plate 13 to rotate. The rotation of the connecting plate 13 drives the movable baffle 14 to rotate. The rotation of the movable baffle 14 can open the filter screen on the lifting plate 15. After the filter screen is opened, the liquid is discharged through the filter screen, and the heavier coal remains on the lifting plate 15. The worker can take out the coal on the lifting plate 15.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
