Technical Field
[0001] The utility model relates to the technical field of coal mine coal preparation equipment, in particular to a flotation coal preparation device. Background Art
[0002] Flotation coal cleaning equipment is a kind of equipment used to separate impurities and minerals, and is mainly used for the selection of materials such as coal and metal ores. It uses the adsorption of bubbles in liquid to make the target minerals rise to the liquid surface and be collected, thereby achieving effective separation of minerals and impurities. When the flotation coal cleaning equipment processes coal, a large amount of foam will float on the surface of the coal. The scraper is used to rotate to drive the foam into the holding tank. Long-term use will easily cause the foam to overflow, which is inconvenient to clean and collect, and it is also inconvenient to clean the foam for a long time.
[0003] A Chinese patent discloses a coal flotation device for coal mine preparation (authorization announcement number CN218796541U), which mainly comprises a pool body, support plates and a first hydraulic cylinder are connected to both sides of the pool body, a top plate and a first motor are connected to the top of the first hydraulic cylinder, a shaft is connected to one end of the first motor, a stirring rod is connected to the outside of the shaft, a second hydraulic cylinder is connected to the bottom wall of the pool body, a frame and a screen are connected to the top of the second hydraulic cylinder, four collecting troughs are connected to the top of the frame, and a waterproof cover is connected to the outside of the second hydraulic cylinder.
[0004] However, there are still some shortcomings in this patent. This patent sets a second hydraulic cylinder, a frame, a screen and a collection tank. After the coal selection is completed, the second hydraulic cylinder is turned on to drive the frame and the collection tank to rise. Through the contact between the collection tank and the inner wall of the pool body, it is conducive to collecting the coal particle foam on the pool wall, and then cleaning it uniformly in the later stage, which solves the problem that some coal particle foam will remain on the inner wall after the coal selection is completed and is difficult to remove; however, a large amount of foam will float on the upper surface of the coal, and a scraper is used to rotate to drive the foam into the holding tank. Long-term use will easily cause the foam to overflow, which is inconvenient to clean and collect, and it is also inconvenient to clean the foam for a long time. Therefore, those skilled in the art provide a flotation coal selection device to solve the problems raised in the above background technology. Utility Model Content
