Description

Technical Field

[0001] The utility model relates to the technical field of flotation equipment, and more specifically to a device for separating electrolyte and carbon powder. Background Art

[0002] A large amount of waste carbon slag is generated during the production process of electrolytic aluminum. These carbon slags contain recyclable electrolytes, carbon powder particles and other substances. Their effective recycling and reuse are of great significance to resource conservation and environmental protection. Harmless treatment of carbon slag can not only avoid environmental pollution, but also recycle the resources therein. It is an important cost-cutting and efficiency-increasing measure. The flotation tank is a device for recycling carbon slag. The flotation method can effectively separate the carbon material and the electrolyte adsorbed thereon.

[0003] A Chinese patent with application number 202120058754.8 discloses an aeration and stirring mechanism for the production of regenerated cryolite, the structure of which includes a flotation box, a feed port is provided on one side of the flotation box, a flotation port is provided on one side of the upper surface of the flotation box, a bottom plate is fixedly installed at the lower part of the inside of the flotation box, and an inflation cavity is formed between the bottom plate and the inner bottom wall of the flotation box, a plurality of first air outlets connected to the inflation cavity are provided on the bottom plate, a rotatable rotating shaft is provided in the middle part of the flotation box, a relatively fixed hollow sleeve rod is sleeved on the outside of the rotating shaft, an air intake gap is left between the inner cavity of the hollow sleeve rod and the rotating shaft, and a plurality of second air outlets are provided on the hollow sleeve rod. The aerated stirring mechanism for the production of regenerated cryolite has an air outlet mechanism added to the bottom and middle of the device, which can increase the effect of air on breaking up the material. However, the stirring device can only stir the slurry at the bottom of the device, which makes the mixing efficiency of air and slurry low. Moreover, when separating the electrolyte and carbon powder, it is necessary to add a decarbonizing agent or the like to the slurry to increase the surface hydrophobicity difference between the carbon powder and the electrolyte, and float the carbon powder by using bubbles as a carrier, so as to achieve the separation effect. However, the device lacks a device for evenly adding additives to the slurry, and can only manually sprinkle the additives on the surface of the slurry. The additives will float on the surface of the liquid and will not sink into the slurry, and cannot effectively play a role in separation.

[0004] Therefore, it is necessary to propose a separation device for electrolyte and carbon powder to solve the above problems. Utility Model Content

[0030] refer to Figure 2 and Figure 5 The interior of the tank body 101 is connected with a hollow tube 122, and the hollow tube 122 is connected with a discharge pipe 123 extending to the interior of the stirring sleeve 110. The connecting pipe 124, the hollow tube 122 and the interior of the discharge pipe 123 are connected. The bottom of the discharge pipe 123 and the hollow tube 122 are connected with a connecting pipe 124. The stirring sleeve 110 is provided with a strip groove 125, and the outer wall of the discharge pipe 123 is arrayed with discharge holes 126 corresponding to the strip groove 125.

[0031] Specifically, refer to Figure 2 The stirring device 104 is connected to an air supply pipe 127 extending into the cavity 107 . The air supply pipe 127 is connected to an external air pump for adding external airflow into the slurry. The air supply pipe 127 is connected to a branch pipe 128 connected to the material tank 112 .

[0032] Specifically, refer to Figure 1 and Figure 2The top of the center rod 105 is connected with a driving device 129, which is composed of a motor, a connecting belt and a pulley. The motor drives the pulley to rotate through the connecting belt, and the pulley is fixed on the center rod 105.

[0033] Specifically, refer to Figure 5 The strip groove 125 is located between two adjacent stirring blades 111 .

[0034] In this embodiment, the outer wall of the tank body 101 is provided with a slurry inlet pipe and an outlet pipe, and the slurry is injected into the tank body 101 through the feed pipe. The stirring device 104 is driven by the driving device 129 to rotate, so as to stir the internal slurry. The stirring device 104 is provided with an air supply pipe 127, which is connected to an external air pump and is used to inject external air into the slurry. The top bracket 103 is provided with a material tank 112, and the additives required to be used can be added into the material tank 112 first. The connecting pipe 124 at the bottom of the material tank 112 extends into the material, and the additives can be uniformly stirred into the slurry by the rotation of the stirring sleeve 110, so as to enhance the separation of the electrolyte and the carbon powder in the material.

[0035] The air supply pipe 127 is connected to a branch pipe 128 connected to the material tank 112, which is used to guide a part of the air flow into the material tank 112, so as to push the material in the material tank 112 into the discharge pipe 123 through the connecting pipe 124 and the hollow pipe 122, and then sprayed into the slurry from the discharge hole 126 on the discharge pipe 123. At the same time, when the central rod 105 rotates, the driving wheel 108 on the outer wall drives the driven wheel 109 to rotate, and the driven wheel 109 drives the stirring sleeve 110 to rotate on the outer wall of the discharge pipe 123. The strip groove 125 on the stirring sleeve 110 corresponds to the position of the discharge hole 126. When the strip groove 125 moves to the position of the discharge hole 126, the discharge hole 126 will be exposed, so that the additive in the discharge pipe 123 can enter the slurry through the discharge hole 126. When the discharge hole 126 is blocked, the discharge hole 126 will be blocked. The stirring sleeve 110 drives the stirring blades 111 on the outer wall to rotate in the slurry, thereby stirring the additives entering the slurry to improve the separation effect.

[0036] When it is necessary to add additives such as decarburizing agents, the top cover 120 on the top of the material tank 112 is opened. At this time, the support frame 117 is pushed by the bottom spring 118 to move upward, and the support frame 117 drives the lifting rod 115 and the top rod 121 to move upward together. The lifting rod 115 drives the bottom baffle 116 to fit the bottom of the discharge bracket 113, thereby blocking the discharge trough 114 opened on the discharge bracket 113, so that the interior of the material tank 112 is disconnected from the connecting pipe 124. At this time, the hollow tube 12 2, the air pressure in the tank body 101 is stable, and the slurry in the tank body 101 will not enter the discharge pipe 123 through the discharge hole 126, which has the function of protecting the discharge pipe 123. At the same time, when the support frame 117 rises, it will drive the retaining ring 119 of the outer wall to move upward, thereby blocking the air outlet of the branch pipe 128 in the material tank 112, so that the branch pipe 128 no longer supplies air to the material tank 112. At this time, the material tank 112 forms a container for placing additives, and the additives to be added can be put into the material tank 112;

[0037] When the top cover 120 is closed, the top cover 120 will press the top rod 121 to move downward, and the top rod 121 will drive the baffle ring 119 and the lifting rod 115 to move downward through the bottom support frame 117, so that the air outlet in the material tank 112 and the discharge trough 114 at the bottom are exposed, and the air flow entering the material tank 112 will push the additive into the connecting pipe 124, and then pass through the hollow tube 122 and the discharge pipe 123 in turn into the slurry, thereby increasing the surface hydrophobicity of the carbon powder and the electrolyte surface, and using bubbles as carriers to float the carbon powder, thereby improving the separation effect.

[0038] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
