[0024] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0026] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., subject to actual needs.

[0027] See also Figures 1 to 5The figure shows a flotation coal cleaning and defoaming device, comprising a mounting plate 1, with telescopic plates 2 provided at both ends of the mounting plate 1, and bolts 4 for connecting to the flotation coal cleaning machine provided on a single telescopic plate 2. The bolt 4 connection is more stable, and the entire device will not shake during operation. At the same time, the telescopic plate 2 can change its length, which can adapt to different environments for installation work and is more convenient. A motor 3 is fixedly mounted on the mounting plate 1, and a flow guide 5 is installed at the bottom of the mounting plate 1. A flow guide 6 is provided inside the flow guide 5, and a plurality of crushing impellers 9 for absorbing and defoaming are provided on the outside of the rotating column 8. A plurality of circular grooves 7 for the liquid to pass through after defoaming are opened in the flow guide 6. The foam broken by the crushing impeller 9 becomes liquid and flows out from the circular groove 7, and solid particles also flow out from the circular groove. In addition, the crushing impeller 9 will not contact the cleaning column 11, and the output end of the motor 3 passes through the mounting plate 1, and the output end of the motor 3 is connected with a cleaning component for cleaning solid particles generated by flotation coal cleaning and defoaming.

[0028] The cleaning assembly includes a rotating column 8 connected to the output end of the motor 3, a connecting rod 10 is connected to the outside of the rotating column 8, a cleaning column 11 is provided at the bottom of the connecting rod 10, and a number of mounting grooves 16 are evenly arranged vertically on the outside of the cleaning column 11. When the movable plate 18 is in the mounting groove 16, the spring 17 is in a compressed state, one end of the spring 17 is connected to the mounting groove 16, and the other end of the spring 17 is connected to a movable plate 18 for cleaning solid particles. The number of movable plates 17 is the same as the number of circular grooves 7. The force generated when the movable plate 18 recovers its deformation after the contraction of the spring 17 cleans out the solid particles blocked in the circular groove 7. The movable plate 18 is rotatably connected to the mounting groove 16, and a mounting column 12 is provided on the top of the cleaning column 11.

[0029] The mounting post 12 is in the shape of a hollow cylinder, and a fixing post 13 is fixedly connected to the inner wall of the mounting post 12. The outer side of the fixing post 13 is fixedly connected to an elastic mounting bracket 14. In this way, when the cleaning post 11 is installed, the pin 15 can be retracted into the fixing post 13, and the mounting bracket 14 will also be deformed. The mounting bracket 14 is V-shaped, and the mounting bracket 14 is provided with two mounting ports. A single mounting port is fixedly connected to a pin 15. The front end cross-section of the pin 15 is semicircular, and the pin 15 is slidingly connected to the inner wall of the mounting post 12. A fixing groove 19 for mounting the cleaning post 11 is provided at the bottom front end of the connecting rod 10, and a card slot 20 that is symmetrically provided in the fixing groove 19 is adapted to the shape of the front end of the pin 15. After the mounting post 12 enters the fixing groove 19, the mounting bracket 14 restores its shape and pushes the pin 15 into the card slot, thereby forming a fixation.

[0030] The motor 3 and the telescopic plate 2 are both existing technologies. Their working principles, sizes and models are irrelevant to the problems solved by this application, so they are not described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0031] Working principle: Fix the mounting plate 1 on the flotation coal cleaning machine, start the motor 3, drive the rotation to rotate, and then the crushing impeller 9 on the rotating column 8 rotates. The rotation of the crushing impeller 9 will generate negative pressure at the bottom of the drainage cover 6, so that the foam enters the drainage cover 5 through the bottom of the drainage cover 5, and the shear force provided by the high-speed rotating crushing impeller 9 is used to tear the foam into pieces, and then enter the circular groove 7 on the drainage cover 5. The liquid is thrown onto the drainage cover 5 by centrifugal force from the circular groove 7 and flows down from the drainage cover 5, while the solid particles will remain in the circular groove 7 on the drainage cover 6. When the rotating column 8 rotates, the connecting rod 10 also drives the cleaning column 11 to rotate. When the cleaning column 11 passes through the circular groove 7, the spring 17 restores its deformation and pushes the movable plate 18 into the circular groove 7, thereby pushing out the solid particles in the circular groove 7, so that the drainage cover 6 will not be blocked.

[0032] When the cleaning column 11 needs to be replaced, the cleaning column 11 is pulled downward, and the fixed column 13 in the mounting column 12 on the cleaning column 11 moves downward, and then the mounting frame 14 on the fixed column 13 moves downward, so that the pin 15 leaves the card slot 20, and then the mounting frame 14 is compressed. After the mounting column 12 completely leaves the fixing slot 19, the mounting frame 14 recovers its deformation and restores the pin 15 to its original position.
