Problems solved by technology

[0002] In the coal washing and washing industry, coal washing with jigging is a commonly used coal washing process. When using jigging coal washing, the coal washing water contains a large amount of fine coal fine particles, which are usually extracted by flotation process. Before entering the flotation machine, the medium-washing coal-water slurry needs to be pretreated by adding chemicals. The existing mechanically agitated slurry preprocessor has a complex structure, high purchase cost, and consumes power, resulting in increased flotation costs; another atomization, The drop-type coal slurry preprocessor adopts a square structure, and the downward flow of the coal slurry is linearly distributed. The dosing point is in the middle, so the mixing is uneven and the treatment effect is not good. The flotation rate of the selected production line is low and the quality is unstable

Embodiment 1

[0024] Example 1, such as Figure 1-5 As shown, a round tower-shaped preprocessor includes a hollow tower body 6, a mixing device is arranged in the tower body flow 6, a liquid distribution device is arranged on the upper end of the tower body 6, and an atomizing device is connected to the liquid distribution device.

[0025] The liquid distribution device includes a cylindrical body 14 with a circular cross section. The cylindrical body 14 is fixedly installed on the upper end of the tower body 6 , and the lower end of the cylindrical body 14 is inserted into the upper end of the tower body 6 for a certain distance.

[0026] The upper end of the cylindrical body 14 is provided with an upper cover 13 , and one side of the cylindrical body 14 is fixedly installed with an untreated pulp delivery pipe 11 , and the unprocessed ore slurry delivery pipe 11 communicates with the cylindrical body 14 .

[0027] The axis of the slurry delivery pipe 11 to be processed is parallel to the ...

Embodiment 2

[0047] Embodiment 2, in above-mentioned embodiment 1, such as Image 6 As shown, each leg 7 is respectively provided with a telescopic rod 20 capable of telescopic expansion, and the leg 7 is provided with a cavity 21 for accommodating the telescopic rod 20, and the lower end of the cavity 21 penetrates to the lower end surface of the leg 7, so that Stretch out at telescoping rod 20.

[0048] A first threaded rod 22 is disposed in the cavity 21 , and the axial direction of the first threaded rod 22 is the same as a certain direction of the telescopic rod 20 .

[0049] The upper end of the first screw rod 22 is fixedly connected to the inner top of the cavity 21 through a bearing seat, and the other end is inserted into the telescopic rod 20 for a certain distance, and the telescopic rod 20 is provided with a screw hole for accommodating the first screw rod 22 .

[0050] The cross section of the telescopic rod 20 is rectangular, which can prevent the telescopic rod 20 from rot...
