Description

Technical Field

[0001] The utility model relates to the field of quartz sand processing, in particular to a flotation device for preparing quartz sand. Background Art

[0002] Before processing quartz sand, workers usually need to float the gravel containing quartz sand to improve the purity of quartz sand. Since the precipitated gravel contains a large amount of quartz sand, the existing flotation device is not convenient for floating the quartz sand mixed in the gravel to the surface of the water when flotating the quartz sand, which leads to insufficient flotation of the quartz sand. In addition, the quartz sand floating on the water surface may also be mixed with unprecipitated gravel, and the existing flotation device is not convenient for settling the floating gravel, which leads to low purity of the floated quartz sand. Utility Model Content

[0003] In order to overcome the above shortcomings, the utility model provides a flotation device for preparing quartz sand, which can make the quartz sand mixed in the sand and gravel float out of the water more fully, thereby more fully floating out the quartz sand, and can also make the floating sand and gravel settle more thoroughly, thereby improving the purity of the quartz sand flotation.

[0004] The technical solution is: a flotation device for preparing quartz sand, comprising a support frame, an outer frame fixedly connected to the support frame, a motor fixedly connected to the support frame, an output shaft of the motor passing through the outer frame, one end of the output shaft of the motor fixedly connected to a transmission shaft, a lower end of the transmission shaft fixedly connected to a lever, the lever contacts the bottom of the inner wall of the outer frame, a fixing frame fixedly connected to the top of the transmission shaft, three curved scrapers fixedly connected to the fixing frame, one end of the three curved scrapers away from the fixing frame all contacts the inner wall of the outer frame, a stirring assembly is provided on the fixing frame, the stirring assembly is connected to the outer frame, the motor starts to drive the fixing frame to rotate, and then the stirring assembly stirs the quartz sand floating on the water surface, so that the floating sand and gravel are more thoroughly precipitated, thereby improving the purity of the quartz sand flotation.

[0005] Furthermore, a discharge hopper is provided on one side of the top of the outer frame.

[0006] Furthermore, the stirring assembly includes a gear ring, which is fixedly connected to the inner wall of the outer frame, and a limiting frame is fixedly connected to the fixed frame. Three rotating shafts are rotatably connected to the limiting frame, and the ends of the three rotating shafts away from the limiting frame are fixedly connected to gears, and the three gears are meshed with the gear ring, and stirring rods are fixedly connected to the three rotating shafts.

[0007] Furthermore, each of the stirring rods is provided with a plurality of protrusions.

[0008] Furthermore, it also includes a caressing plate, and three of the caressing plates are fixedly connected to the fixing frame.

[0009] The beneficial effects of the utility model are as follows: 1. The utility model drives the lever and the curved scraper to rotate together through a motor. When the lever rotates, the sand and gravel precipitated at the bottom are stirred, so that the quartz sand mixed at the bottom floats to the water surface, so that the subsequent flotation is more sufficient. When the curved scraper rotates, it passes through the discharge port of the outer frame. The curved scraper will lift the outer quartz sand upward for a distance, and then push the quartz sand out of the discharge hopper of the outer frame, so that the water mixing is reduced while pushing out the quartz sand, and then the quartz sand with less water content emerges, which is convenient for subsequent processing.

[0010] 2. The utility model rotates the fixing frame to make the stirring rod rotate and self-rotate, so that the stirring rod stirs the quartz sand and gravel floating on the water surface, and then makes the floating gravel settle, thereby improving the purity of the quartz sand floated. At the same time, the smoothing plate will smooth the water surface stirred by the stirring rod while rotating, so that the flotation is more stable. BRIEF DESCRIPTION OF THE DRAWINGS
