Circular flotation machine central froth tank is an indispensable part in the flotation process, and its design directly affects the flotation efficiency and the recovery rate of minerals. For example, the utility model patent with publication number CN218690487U discloses a multi-tooth froth tank, which comprises a tank body and a cover plate. The cover plate is detachably connected to the top opening end of the tank body. A stirring assembly is inserted into the surface of the cover plate. A flow resistance assembly is installed inside the tank body. A guide ring is equidistantly welded to the inner surface of the cover plate. An annular spray pipe is slidably inserted into the guide ring. A spray head is connected to the lower surface of the annular spray pipe. A gear strip is fixedly connected to the inner wall of the annular spray pipe. A driving assembly is arranged on the surface of the cover plate. When the tank body needs to be cleaned, an external water pump is started by an external power source.

Bolts 6 are disposed inside both the first half-foam tank 2 and the second half-foam tank 3, and a limit mechanism 7 is disposed inside the bolt 6.

[0020] Please see Figure 3 , Figure 4 The limiting mechanism 7 includes an annular groove 71. The bolt 6 has an annular groove 71 inside. A slider 72 is slidably connected inside the annular groove 71. A support ring 73 is fixedly connected to the end of the slider 72 away from the annular groove 71. A pull rod 74 is fixedly connected to the side of the support ring 73 away from the slider 72. A handle 75 is fixedly connected to the end of the pull rod 74 away from the support ring 73. By designing the handle 75, the pull rod 74 can be moved. A connecting seat 76 is provided on the first half foam tank 2 and the second half foam tank 3. A connecting seat 76 is provided on the first sealing gasket 4 and the second sealing gasket 5. A pull rod 74 is slidably connected inside the connecting seat 76. A spring 77 is provided on the outside of the pull rod 74. One end of the spring 77 is fixedly connected to the support ring 73, and the other end of the spring 77 is fixedly connected to the connecting seat 76. By designing the spring 77, the support ring 73 has an elastic force.

[0021] Please see Figure 3 , Figure 4 The connecting seat 76 has a guide groove 78 inside, and a guide block 79 is slidably connected inside the guide groove 78. The guide block 79 is fixedly connected to the support ring 73. By designing the guide block 79, the support ring 73 can be guided. The pull rod 74 has a slot 710 inside, and a locking block 711 is slidably connected inside the slot 710. The locking block 711 has a sliding groove 712 inside, and a guide rod 713 is slidably connected inside the sliding groove 712.

By pulling the slider 72 to move, after the slider 72 moves to the designated position, the bolt 6 is installed in the designated position on the device. Then the slider 72 is moved into the annular groove 71, thereby limiting the bolt 6 and preventing the bolt 6 on the device from loosening after long-term use.

[0022] The specific implementation process of this utility model is as follows: Before using the device, pull the handle 75 to move away from the connecting seat 76. The movement of the handle 75 drives the pull rod 74 to move. The movement of the pull rod 74 drives the support ring 73 and the slot 710 to move. The movement of the slot 710 causes misalignment with the locking block 711, thereby causing the locking block 711 to move towards the elastic sponge 714. The movement of the locking block 711 drives the sliding groove 712 to move. The movement of the locking block 711 compresses the elastic sponge 714. The movement of the support ring 73 drives the guide block 79 and the slider 72 to move. The movement of the support ring 73 causes the spring 714 to move. 7. After the slider 72 is compressed and moved to the designated position, the bolt 6 is installed in the designated position on the device. Then, the handle 75 is released. The elastic force of the spring 77 pushes the support ring 73 to move. The movement of the support ring 73 drives the pull rod 74, slider 72 and slot 710 to move. After the slider 72 moves into the annular groove 71, the elastic force of the elastic sponge 714 pushes the locking block 711 to move. The locking block 711 moves into the slot 710, thereby limiting the pull rod 74 and thus limiting the bolt 6, preventing the bolt 6 on the device from loosening after long-term use.

[0023] This device collects foam into the sluice box in a timely manner, reducing the residence time of foam in the flotation tank and maximizing the foam recovery rate. The foam sluice box device fundamentally reduces the foam conveying distance to the edge of the sluice box, reduces the residence time of foam in the flotation tank, and maximizes the foam recovery rate. The internal foam pusher of the circular flotation machine and the external foam pusher cone of the tank body work together to push the foam towards the first half foam tank 2 and the second half foam tank 3, conveying all the rapidly floating and fully dissociated particles to the first half foam tank 2 and the second half foam tank 3.
