Description

Technical Field

[0001] The utility model belongs to the technical field of mineral separation equipment, in particular to a flotation machine with a dosing function. Background Art

[0002] Flotation is a technical method to separate useful minerals from ores based on the different physical and chemical properties of the surface of mineral particles. It is widely used in the separation of fine and ultra-fine materials. Flotation machine is a mechanical equipment to complete the flotation process. In the flotation machine, the slurry that reacts with the reagent is stirred and aerated so that some of the mineral particles are selectively fixed on the bubbles, float to the surface of the slurry and are scraped out to form foam products, while the rest are retained in the slurry to achieve the purpose of separating minerals. One or more reagents need to be added during the flotation production process. The types of reagents added include inhibitors, activators, adjusters, collectors, etc.

[0003] The main way to add reagents to the existing flotation machine is to directly insert the reagent pipe into the middle box or flotation tank of the flotation machine, which shortens the reaction time between the reagent and the slurry, resulting in poor dispersion effect and greatly affecting the flotation index. At the same time, the reagent addition pipe is laid on the flotation machine platform, which not only increases the difficulty of equipment production and assembly, but also brings inconvenience to production operation and equipment maintenance. Therefore, we hope to design a flotation machine with a dosing function to solve this problem. Utility Model Content

[0030] See also Figure 1 to Figure 2 The feed pipe 230 is connected to the feeding device of the flotation machine body 100, and the lower end of the feed pipe 230 is placed inside the upper end of the mixing barrel 240, and the lower end of the feed pipe 230 does not extend to the first mixing bucket 260 on the upper side of the mixing barrel 240. By setting the mixing barrel 240, the reagent can be directly mixed into the raw material without arranging the dosing pipeline and related dosing equipment on the flotation machine body 100, which greatly reduces the difficulty of assembling the equipment and is also convenient for later users to overhaul and maintain.

[0031] An inclined surface 241 is disposed inside the lower end of the mixing cylinder 240. The inclined surface 241 is arranged in a structure that is higher on the left and lower on the right, and the inclined surface 241 has an inclination angle of 30 degrees.

[0032] As the first embodiment of the utility model, by setting a dosing assembly 200, the entire dosing assembly 200 is independent of the flotation machine body 100, so that the flexibility of equipment assembly can be improved. In actual use, the raw material is introduced into the mixing cylinder 240 through the feed pipe 230, and the agent is transported to the mixing cylinder 240 through the delivery pipe 220. After the two are mixed inside the mixing cylinder 240, they are introduced into the feed box 110 of the flotation machine body 100 through the discharge pipe 250 under the action of gravity. The agent can be directly mixed into the raw material without arranging the dosing pipeline and related dosing equipment on the flotation machine body 100, which greatly reduces the difficulty of equipment assembly and is also convenient for later users to perform inspection and maintenance.

[0033] See also Figures 1 to 4 The mixing bucket 260 includes a bottom plate 261, a cone bucket 263, a spherical panel 265 and a connecting rod 266. The cross section of the bottom plate 261 is an upwardly arched arc structure, and the edge of the bottom plate 261 is welded and fixed to the lower end of the cone bucket 263.

[0036] The maximum diameter of the spherical panel 265 is smaller than the maximum diameter of the bottom plate 261 , and the cross section of the spherical panel 265 is an upwardly arched arc structure. The setting of the dosing assembly 200 achieves the purpose of rapid self-mixing through the effect of gravity impact.

Under the action of the ball panel 265, the medicine and the material are mixed due to the collision with the ball panel 265, and splashed toward the inner wall of the lower end of the cone bucket 263, and then collided and mixed with the inner wall of the lower end of the cone bucket 263 for the second time, and then fell onto the bottom plate 261, and moved downward through the leakage hole 262 to reach the next mixing bucket 260, and the above-mentioned collision and mixing steps are repeated until the raw materials and the medicine are mixed and then, under the action of gravity, the medicine and the raw materials are mixed. The material enters the discharge pipe and is transported to the flotation machine body 100, where it achieves the purpose of rapid self-mixing through the effect of gravity impact, and mixes the reagent with the raw material without the need for using stirring equipment components, thereby simplifying the structure of the equipment and reducing the energy consumption required for the operation of the equipment, in line with the concept of energy saving and environmental protection, and reducing production costs. The setting of the overflow hole 264 can assist in discharging the material when the leakage hole 262 is insufficient to discharge, thereby avoiding excessive accumulation of material and reducing the self-mixing effect (a small amount of accumulation of material will not affect the normal self-mixing effect, mainly because a small amount of accumulation of material is prone to occur in the first mixing bucket 260, and the overflow hole 264 can avoid excessive accumulation of material in the first mixing bucket 260).
