One end of the discharge port 20 is fixedly connected to the other side of the box body 1, and the other end of the discharge port 20 is fixedly connected to the collecting tank 21. The inner wall of the collecting tank 21 is rotatably connected to the impeller 22, one side of the collecting tank 21 is fixedly connected to the small driving motor 23, and the outside of the collecting tank 21 is fixedly connected to the inclined plate 24. The rotating shaft of the impeller 22 passes through one side of the collecting tank 21 and is fixedly connected to the output shaft of the small driving motor 23, so as to improve the purity of the collected foam.

[0031] A high-pressure gas chamber 13 is arranged at the bottom of the box body 1, a plate 14 is installed on the top of the high-pressure gas chamber 13, a plurality of bubble ejectors 15 are fixedly connected to the top of the plate 14, a microporous partition 16 is arranged on the top of the bubble ejector 15, and the peripheral side of the microporous partition 16 is fixedly connected to the inside of the box body 1, so as to control the size of the bubbles and weaken the impact force of the high-pressure gas.

[0032] A U-shaped groove 17 is provided at the bottom of the inner wall of the medicine box 6, and a plurality of atomizing nozzles 18 are fixedly connected to the bottom of the U-shaped groove 17, so that the medicine can be well dispersed and integrated with the slurry.

[0033] A stirring chamber 19 is provided inside the box body 1 , and the stirring chamber 19 is located above the high-pressure gas chamber 13 .

[0034] The material inlet 5 penetrates the box body 1 and is fixedly connected and extends to the inside of the material box 4 , the medicine inlet 7 penetrates the box body 1 and is fixedly connected and extends to the inside of the medicine box 6 , and the air inlet 11 penetrates the box body 1 and is fixedly connected and extends to the inside of the high-pressure air chamber 13 .

[0035] Working principle: Before the flotation of scheelite, a certain amount of water is injected into the stirring chamber 19, and then the slurry is added into the material box 4 from the feed port 5, and the reagent is added into the reagent box 6 from the reagent port 7.
