[0028] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a new type of quartz sand flotation machine provided by the utility model; Figure 2 for Figure 1 The internal structure diagram of the machine slot 1 is shown; Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. The novel quartz sand special flotation machine comprises: a machine tank 1, the machine tank 1 is shallow, and a bubble scraping device 2 is arranged on the surface of the machine tank 1;

[0030] A driving assembly 3, wherein the driving assembly 3 is arranged on the top of the scraping device 2;

[0031] A mixing and stirring component 4, the mixing and stirring component 4 is arranged inside the machine tank 1, the mixing and stirring component 4 includes an air inlet 41, the air inlet 41 is fixedly installed at the bottom of the scraping device 2, the number of the air inlet 41 is multiple, the outer surface of the air inlet 41 is fixedly connected to a stirring impeller 42, and the stirring impeller 42 is provided with a blade with an enlarged diameter;

[0032] An impeller cover plate 43, wherein the impeller cover plate 43 is fixedly mounted on the top of the stirring impeller 42, and the impeller cover plate 43 is arranged with an enlarged diameter;

[0033] A stator 5, wherein the stator 5 is fixedly mounted on the outer surface of the stirring impeller 42;

[0034] The scraping bubble component 6 is arranged on the surface of the machine tank 1.

[0035] The shallow trough flotation is adopted to reduce the depth of the flotation tank body of the machine tank 1, reduce the path of foam carrying concentrate, reduce the probability of material settling in the tank per unit time, and effectively reduce the settling of the material. The height is the height controlled by calculation according to the material conditions. The lower stirring impeller 42 and the impeller cover 43 are increased according to the material conditions. The stirring impeller 42 is increased, and the corresponding linear speed becomes larger. The range of the reagent, material, and air bubble thrown out by the centrifugal force at the bottom will become larger, which increases the distribution area of ​​the reagent and air bubble in the material per unit time, and improves the flotation efficiency. The stator 5 and the rotor are adjusted according to this. The particle size is between -0.7 and +0.45 mm, and then through this calculation, we can see the area it can be dispersed, how much area it can occupy in the entire volume, the proportion it occupies, its particle size distribution, and then its centrifugal force to calculate it. The lower impeller adopts a new impeller cover 43, which is effectively combined with the stirring impeller 42. The increased aeration can make up for the insufficient air intake. The lower impeller can effectively increase the stirring force, which can take into account both the air intake and the stirring effect, and the number of air inlet holes 41 is increased. The gas is thrown out with the centrifugal force and mixed with the medicine and materials.

[0046] The working principle of the new quartz sand flotation machine provided by the utility model is as follows:

[0047] After the quartz sand and the reagent are fully mixed, they are fed into the bottom of the machine tank 1 through the air inlet pipe 22. After the stirring motor 33 is started, the stirring impeller 42 is driven to rotate through the first belt 32 and the bearing seat 31, and a negative pressure is formed in the wheel cavity, so that the slurry under the bottom of the tank and in the tank enter the mixing zone through the lower suction port and the upper suction port of the stirring impeller 42 respectively, and the air enters the mixing zone along the reagent pipe 23. The slurry, air and reagent are mixed here. Under the action of the centrifugal force of the stirring impeller 42, the mixed slurry enters the mineralization zone, and the air forms bubbles and is crushed, and fully contacts with the coal particles to form mineralized bubbles. Under the action of the stator 5 and the impeller cover plate 43, the air is evenly distributed in the cross section of the internal tank body of the machine tank 1, and moves upward into the separation zone, enriched to form a foam layer, and the foam scraping motor 63 drives the foam scraping plate 61 to rotate through the second belt 62 to discharge it, forming clean coal foam.
