[0027] The utility model is further described below in conjunction with embodiments.

[0028] Example: Refer to Figures 1 to 4 A low-grade bauxite beneficiation flotation bubble generator comprises a bubble generator body 1, the bottom of the bubble generator body 1 is connected to a liquid inlet pipe 2, and the top is connected to a liquid outlet pipe 3, the outer wall of the liquid outlet pipe 3 is movably sleeved with a bubble generating cover 4, the inner wall of the bubble generating cover 4 is fixedly connected to a ring-shaped rubber sealing pad 17, the ring-shaped rubber sealing pad 17 is airtightly attached to the surface of the liquid outlet pipe 3, the sealing between the bubble generating cover 4, the ring-shaped rubber sealing pad 17 and the liquid outlet pipe 3 is increased to prevent liquid from flowing out.

[0029] A height adjustment component is provided between the bubble generating cover 4 and the bubble generator body 1, and a plurality of bubble generating holes 5 are provided on the top of the bubble generating cover 4. The height adjustment component includes a fixing card 6 fixedly connected to the outer wall of the bubble generator body 1, a rack 7 is movably provided in the fixing card 6, the rack 7 is vertically arranged, and a disassembly and assembly component is provided between the rack 7 and the bubble generating cover 4. A motor 8 is fixedly connected to the top of the bubble generator body 1. The motor 8 adopts a NEMA17 stepper motor with a self-locking function, which can maintain its current position or prevent reverse rotation when the current supply is stopped.

[0030] The end of the output shaft of the motor 8 is fixedly connected with a gear 9, and the gear 9 is meshed with the rack 7. When the bubble generator body 1 is in use, the slurry is added into the interior from the liquid inlet pipe 2, so that with the cooperation of the bubble generator body 1 and the bubble generating cover 4, a large number of micro bubbles can be generated from the slurry. The bubble generator body 1 is an existing public technology, and the present technical scheme will not be described in detail. When the height of the bubble generating cover 4 needs to be adjusted, the motor 8 is started to drive the gear 9 to rotate, and then the rack 7 meshed with it is used to drive the bubble generating cover 4 to move along the outer wall of the liquid outlet pipe 3. The height of the bubble generating cover 4 can be adjusted to achieve the effect of adjusting the height of the bubbles in the device according to actual needs, thereby improving the applicability of the device.

[0031] The disassembly and assembly component is used to install the bubble generating cover 4 on the bubble generator body 1, and remove it from the bubble generator body 1. The disassembly and assembly component includes a fixing rod 10 fixedly connected to the surface of the bubble generating cover 4, and the outer wall of the fixing rod 10 is movably sleeved with a clamping rod 11, and the end of the clamping rod 11 is provided with a groove 12 matching the fixing rod 10, and a spring 13 is commonly connected between the surface of the groove 12 and the end of the fixing rod 10, and the end of the clamping rod 11 is fixedly connected with a clamping block 14, and the clamping block 14 movably penetrates the side wall of the rack 7. When the clamping block 14 and the rack 7 are clamped, the bubble generating cover 4 can be installed on the bubble generator body 1.

Cleaning and maintenance are carried out for recycling. When the maintenance is completed, the bubble generating cover 4 is first put on the outer wall of the liquid outlet pipe 3, and then the bubble generating cover 4 is moved down and the clamping rod 11 is aligned with the positioning groove 16. At the same time, the clamping rod 11 is pressed inward to compress the spring 13. When the clamping rod 11 contacts the bottom of the positioning groove 16, the clamping rod 11 is released. Then, under the action of the spring 13, the clamping rod 11 quickly returns to its position until the clamping block 14 is completely inserted into the clamping hole 15. The bubble generating cover 4 can be quickly disassembled and assembled for cleaning and maintenance, to prevent it from being blocked due to long-term use, and to ensure the normal use of the device.
