An oil retaining ring 208 is provided on one side of the main shaft groove 207.

[0028] The drive assembly 3 includes a pulley 301. A shaft end retaining ring 302 is installed on the top of the pulley 301. A fixing bolt 303 is threadedly connected inside the shaft end retaining ring 302. The bottom of the fixing bolt 303 is threadedly connected to a main drive shaft 304. A rubber pad 305 is provided at the bottom of the main drive shaft 304. An impeller 306 is installed at the bottom of the main drive shaft 304. An air distributor 307 is provided inside the impeller 306. A cover plate 308 is provided above the impeller 306.

[0029] In this embodiment, as Figure 1 and Figure 2 shown, the flotation cell 101 is composed of two half center cylinders, and stoppers 103 can be inserted at the ports of the two half center cylinders; by setting stoppers 103 at the two ports of the flotation cell 101 to control the flotation operation power of the flotation machine, and cooperating with the adjustment of the rotation speed of the main drive shaft 304, the formation of the foam layer can be effectively controlled, thereby improving the use effect of the flotation machine.

[0030] In this embodiment, as Figure 2 and Figure 5 shown, the flange 102 at the bottom of the flotation cell 101 is flange-connected to the cover plate 308, and a rubber pad 305 is provided between the main drive shaft 304 at the top of the impeller 306 and the flange 102; by setting the flange 102 to connect the flotation cell 101 and the impeller 306, the stability of the flotation cell 101 when the impeller 306 rotates is improved, thereby improving the flotation effect of the flotation machine.

[0031] In this embodiment, as Figure 3 and Figure 4 shown, a bearing chamber is provided inside the bearing body 201, and the tubing 205 forms a plug-in connection structure with the bearing chamber by penetrating the bearing body 201, and an oil retaining ring 208 and a skeleton oil seal 106 are respectively provided at the upper and lower ends of the bearing chamber; by providing a bearing chamber inside and cooperating with the skeleton oil seals 106 and oil retaining rings 208 at both ends, the rotation effect between the bearing chamber and the inner main drive shaft 304 is increased, thereby reducing the energy loss when the main drive shaft 304 rotates, thereby reducing the energy consumption of the flotation machine during operation, and thereby reducing the use cost of the flotation machine.

[0032] In this embodiment, as Figure 2 and Figure 4As shown, calcium-based grease is provided on the outside of the oil baffle ring 208 and the outside of the skeleton oil seal 106. The calcium-based grease applied externally increases the sealing performance of the bearing chamber, facilitating the rotation of the main drive shaft 304, further improving the rotation effect of the main drive shaft 304, and thus enhancing the flotation effect of the flotation machine.

[0033] In this embodiment, as Figure 1 and Figure 5 shown, the top of the main drive shaft 304 is fixedly connected by a threaded fixing bolt 303 to form a fitting insertion structure with the center of the pulley 301. The pulley 301 and the main drive shaft 304 are fixed by the fixing bolt 303 in cooperation with the shaft end retaining ring 302. While further improving the driving effect of the pulley 301 on the main drive shaft 304, it also facilitates the replacement of the pulley 301 when it is damaged, and improves the rotation effect of the main drive shaft 304 driving the impeller 306.

[0034] In this embodiment, as Figure 1 shown, the stator 4 is installed obliquely above the periphery of the impeller 306, and the stator 4 is formed by twenty-four radially short blades in a ring shape. By arranging multiple short blades on the outside to form the stator 4, the tangentially rotating pulp flow generated by the impeller 306 is converted into a radial pulp flow, which helps the pulp to be recycled in the tank, and thus improves the flotation efficiency of the flotation machine.

[0035] The usage method and advantages of the present utility model: The pulp in this pneumatic flotation machine is turbulent. When in use, the working process is as follows:

[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, first, the operator fixes the stator 4 in the flotation cell. Then, after the pulp enters the flotation cell, the entire flotation machine is placed into the stator 4, and the pulley 301 is driven to drive the main drive shaft 304 to rotate, thereby driving the impeller 306 below the main drive shaft 304 to rotate. Next, air is injected into the flotation machine from the air inlet pipe 202. After the air enters the air distributor 307 below, through the rotation of the impeller 306 and the action between multiple short blades in the stator 4, air bubbles are formed in the pulp, so that the ore particles in the pulp selectively adhere to the air bubbles, thereby achieving the purpose of flotation. Finally, when control is required, it is controlled by controlling the rotation speed of the pulley 301 and the method of inserting a wooden plug 103 into the flotation chamber 101. At the same time, the oil cup 203 in the bearing body 201, in cooperation with the inner connecting pipe 204 and the oil pipe 205, injects lubricating oil into the bearing chamber, which can effectively maintain the rotation effect of the main drive shaft 304 in the bearing body 201, and thus improve the usage effect of the flotation machine.
