DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments.

[0023] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] like Figures 1-4 As shown, an electrolytic aluminum slag flotation machine capable of filtering includes a flotation tank 1, support legs 2, a vertical frame 6, a cylinder 7, a frame 8, a drive shaft 9, a support frame 10, and filter screens 11. The support legs 2 are located at the bottom of the flotation tank 1, the vertical frame 6 is fixed to the top of the flotation tank 1, the cylinder 7 is fixedly installed on the top of the vertical frame 6, and the output end of the cylinder 7 is fixedly connected to the frame 8 to drive the frame 8 to rise and fall. There are two drive shafts 9, both of which are rotatably connected to the frame 8. One end of each of the two filter screens 11 is fixedly connected to the two drive shafts 9 respectively. Each filter screen 11 is provided with a support frame 10, and each drive shaft 9 is connected to a drive assembly that drives its rotation.

[0025] Specifically, when the two filters 11 and the support frame 10 are adjusted to a vertical state, it will not affect the upward movement. Furthermore, when the frame is vertical, the height is half the plane of the flotation box 1 cavity, which will not affect the stirring inside the flotation box 1. At the same time, when the frame is adjusted to a horizontal state, it can cover the cavity of the flotation box 1 to filter the floating impurities.

[0026] Furthermore, the drive assembly includes a passive sprocket 12, a motor 13, a drive sprocket 14, and a chain 15. The motor 13 is fixed to the top of the frame 8, the drive sprocket 14 is mounted on the output shaft of the motor 13, the passive sprocket 12 is fixed to the end of the drive shaft 9 away from the filter screen 11, and the chain 15 is arranged around the outside of the passive sprocket 12 and the drive sprocket 14.

[0027] Specifically, the motor 13 is located at the top of the frame 8 to prevent liquid from damaging the motor 13. The chain 15 drives the passive sprocket 12 below to rotate, which in turn causes the drive shaft 9 and the filter screen 11 to rotate synchronously, adjusting the angle of the support frame 10.

[0028] Furthermore, a stirrer 5 is installed at the bottom of the flotation tank 1 to stir the carbon slag inside the tank.

[0029] Furthermore, it also includes a support crossbeam 16, an electric linear slide 17, a clamp 18, and a rubber strip 19. The support crossbeam 16 is fixedly mounted across the top of the flotation tank 1. The electric linear slide 17 is fixedly mounted on the support crossbeam 16. The clamp 18 is fixedly connected to the output part of the electric linear slide 17 and is placed horizontally in the cavity. The rubber strip 19 is arranged along the length of the clamp 18 at the bottom of the clamp 18 to clean the surface of the support frame 10.

[0030] Specifically, when the support frame 10 filters the carbon residue, it rises to contact the rubber strip 19, and then the clamp holder 18 is driven to translate by the electric linear slide 17, so that the rubber strip 19 sweeps the impurities on the support frame 10.

[0031] Further, the top side of the flotation tank 1 is provided with a discharge hopper 3 to discharge the impurities.

[0032] Further, one end of the filter screen 11 is fixedly connected to the transmission shaft 9, so that the filter screen 11 and the support frame 10 can be adjusted to be horizontal or vertical by the support of the transmission shaft 9.

[0033] Further, the shaft of the air cylinder 7 is vertically arranged to drive the frame 8 to vertically lift.

[0034] Further, the electric linear slide 17 is horizontally arranged on the support cross seat 16, and one end thereof faces the discharge hopper 3.

[0035] In the above structure, the motor 13 is powered to drive the driving sprocket 14 to rotate, and then the passive sprocket 12 is synchronously rotated by the chain 15, so that the filter screen 11 and the support frame 10 are driven to rotate, and the support frame 10 changes the angle to be horizontal or vertical; the carbon residue and water are discharged into the flotation tank 1, and a flotation reagent is added, at this time, the support frame 10 is adjusted to be vertical, the agitator 5 is started to stir the residue water in the flotation tank 1, and the mixture is filled with air to make the system foam, the hydrophobic carbon adheres to the bubbles and floats to the foam layer, and the hydrophilic electrolyte sinks, so that the carbon and the electrolyte in the carbon residue are separated, after rising, the motor 13 is started to drive the support frame 10 to rotate and adjust to be horizontal, the air cylinder 7 is started to collect and drive the frame 8 to rise, and then the support frame 10 rises, the rising impurities are filtered on the support frame 10, the electric linear slide 17 is started to drive the rubber strip 19 to translate, and the impurities on the support frame 10 are swept, and the flotation is completed.

[0036] The above shows and describes the basic principles, main features and advantages of the present application.
