Description

Technical Field

[0001] The utility model belongs to the technical field of slag treatment, and particularly relates to an electrolytic aluminum carbon slag precipitation fishing device. Background Technique

[0002] During the production process of electrolytic aluminum, part of the alumina sintered block will fall into the electrolytic cell. To avoid interference caused by the agglomerated part, the alumina sintered block is usually scooped out with a carbon slag spoon. This operation method is time-consuming and laborious, and the labor intensity of workers is very high. When using tools, they are relatively close to the cell, and the high-temperature electrolyte is easy to splash on the body and cause burns. A Chinese patent proposed an electrolytic aluminum carbon slag precipitation fishing device with the publication number (CN220643289U). This patented technology uses a transparent plate to facilitate observation while avoiding splashing high temperature, and uses a closable alumina slag grabbing device instead of an iron hook. After the steel spoon scoops up the alumina carbon slag precipitation, the operator can control the steel cover plate to close the upper opening of the steel spoon on one side of the handle through the steel adjusting rod without approaching the steel spoon. Thus, during the process of withdrawing the steel spoon from the electrolytic cell, the alumina carbon slag precipitation entering the steel spoon can be prevented from being washed down by the aluminum liquid, improving the extraction efficiency of the alumina carbon slag precipitation. However, the technical defect is that its grasping type filtering structure can only filter out large agglomerated alumina carbon slag, and the aluminum liquid attached to the surface of the alumina carbon slag after being shoveled cannot quickly flow back to the inside of the electrolytic cell, and it does not have the function of treating the small particle aluminum carbon slag carried back to the electrolytic cell by the aluminum liquid, so the use effect is not ideal. Content of the Utility Model

[0003] The utility model provides an electrolytic aluminum carbon slag precipitation fishing device to solve the problems raised in the background technique.

[0004] The utility model provides the following technical solution: An electrolytic aluminum carbon slag precipitation fishing device includes a linear displacement driving control component, a driving control motor, and a collecting swing arm. The output end of the linear displacement driving control component is fixedly connected to the driving control motor, and the output end of the driving control motor is fixedly connected to the collecting swing arm. One end of the collecting swing arm is provided with a filtrate slag collecting component, which is composed of a carbon slag separation outer hopper, a liquid flow slag separating component, and a main screening hopper. The carbon slag separation outer hopper is fixedly connected to the collecting swing arm, the carbon slag separation outer hopper is fixedly connected to the main screening hopper, and a gap is reserved between the carbon slag separation outer hopper and the main screening hopper. The liquid flow slag separating component is arranged horizontally and equidistantly inside the carbon slag separation outer hopper, and the liquid flow slag separating component is used for isolation after the carbon slag is shoveled into the carbon slag separation outer hopper and for filtering out the attached aluminum liquid.

[0005] Among them, the liquid flow slag separation component includes a shoveling separation tank, a vertical separation surface, and a lifting guide cutting surface. The shoveling separation tank is arranged inside the outer carbon slag separation hopper. The vertical separation surface and the lifting guide cutting surface are arranged in the shoveling separation tank, and the vertical separation surface and the lifting guide cutting surface are symmetrically distributed.

[0006] Among them, an inlet through hole is arranged at the bottom of the shoveling separation tank, and the inlet through hole is used to guide the molten aluminum to the surface of the outer carbon slag separation hopper.

[0007] Among them, a guide vane is fixedly connected to the outer carbon slag separation hopper, and a detachable collection box is screwed and fixed to the bottom of the open end of the main screening hopper.

[0008] Among them, two symmetrically distributed outer isolation plates are fixedly connected to the outer wall of the main screening hopper, and the outer isolation plates are used for lateral interception after the carbon slag is shoveled in.

[0009] The beneficial effects of the present utility model are as follows: By shoveling into the electrolytic cell through the main screening hopper, and guiding the carbon slag into the inner side of the bucket structure formed by the carbon slag separation outer hopper and the outer isolation plate through the guide vane. At this time, during the inward movement of the carbon slag, the vertical separation surface inside the shoveling separation tank restricts the sliding of the carbon slag, realizing the cut-off of the carbon slag. When cutting off, the molten aluminum attached to the surface of the carbon slag is guided along the passing gap formed between the carbon slag separation outer hopper and the main screening hopper through the inlet through hole, that is, the inclined main screening hopper guides the molten aluminum into the inner side of the detachable collection box. The detachable collection box secondary filters the small particle aluminum carbon slag remaining in the molten aluminum, avoiding the small particle aluminum carbon slag from flowing back into the electrolytic cell together with the molten aluminum, thereby effectively improving the treatment completion degree.

[0015] Please refer to Figures 1 - 3 , the present utility model provides the following technical solutions: an electrolytic aluminum carbon slag precipitation and fishing device, including a linear displacement drive control component 1, a drive control motor 2 and a collection swing arm 3. The output end of the linear displacement drive control component 1 is fixedly connected to the drive control motor 2, and the output end of the drive control motor 2 is fixedly connected to the collection swing arm 3. One end of the collection swing arm 3 is provided with a filtrate and slag collection component 4. The filtrate and slag collection component 4 is composed of an outer carbon slag separation hopper 41, a liquid flow and slag separation component 42 and a main screening hopper 43. The outer carbon slag separation hopper 41 is fixedly connected to the collection swing arm 3, and the outer carbon slag separation hopper 41 is fixedly connected to the main screening hopper 43, and a gap is reserved between the outer carbon slag separation hopper 41 and the main screening hopper 43. The liquid flow and slag separation component 42 is arranged horizontally and equidistantly inside the outer carbon slag separation hopper 41. The liquid flow and slag separation component 42 is used for isolating the carbon slag after it is shoveled into the outer carbon slag separation hopper 41 and for filtering out the attached aluminum liquid.

[0016] In this embodiment, the linear displacement drive control component 1 adopts an electric telescopic cylinder, and the drive control motor 2 selects a motor as the flipping drive of the collection swing arm 3. When treating the carbon slag inside the electrolytic cell, first, the main screening hopper 43 is driven by the linear displacement drive control component 1 to shovel into the inside of the electrolytic cell. During the shoveling process, the carbon slag is guided by the inclination angle of the guide vane 411 to enter the inside of the bucket structure formed by the outer carbon slag separation hopper 41 and the outer isolation page plate 44 until the carbon slag reaches the inside of the shoveling separation tank 421 during the movement process. The vertical separation surface 422 inside the shoveling separation tank 421 restricts the sliding of the carbon slag, so that the carbon slag stops. After stopping, the aluminum liquid on the surface of the carbon slag flows through the inlet through hole 424 into the through gap formed between the outer carbon slag separation hopper 41 and the main screening hopper 43. Because the main screening hopper 43 is tilted, at this time, the aluminum liquid is guided into the inside of the separated collection box 5, and the small particle aluminum carbon slag remaining in the aluminum liquid is filtered again through the separated collection box 5 to prevent the small particle aluminum carbon slag from flowing back into the inside of the electrolytic cell synchronously with the aluminum liquid, thereby effectively improving the treatment completion degree. After the aluminum liquid filtration rate is completed, the main screening hopper 43 is driven by the linear displacement drive control component 1 to move outside the electrolytic cell, and the outer carbon slag separation hopper 41 is flipped counterclockwise by the drive control motor 2. The carbon slag inside the shoveling separation tank 421 is discharged to the outside through the outer carbon slag separation hopper 41 under the guiding action of the lifting guide cut surface 423.

[0017] The liquid flow slag separation component 42 includes a shoveling separation groove 421, a vertical separation surface 422, and a lifting guide cutting surface 423. The shoveling separation groove 421 is opened on the inner side of the slag separation outer hopper 41. The vertical separation surface 422 and the lifting guide cutting surface 423 are arranged symmetrically in the shoveling separation groove 421.

[0018] In this embodiment, when the slag separation outer hopper 41 is placed horizontally, the slag entering the inner side of the shoveling separation groove 421 is intercepted by the shoveling separation groove 421 and will not flow back to the inner side of the electrolytic cell. When the slag separation outer hopper 41 is in a counterclockwise flipping state, the lifting guide cutting surface 423 plays a guiding role for the slag on the inner side of the shoveling separation groove 421, so that the slag rolls from the slag separation outer hopper 41 to the outer slag collection box through the lifting guide cutting surface 423.

[0019] An introduction through hole 424 is opened at the bottom of the shoveling separation groove 421. The introduction through hole 424 is used to guide the aluminum liquid to the surface of the slag separation outer hopper 41; the introduction through hole 424 is used to guide the aluminum liquid attached to the surface of the slag to the surface of the main screening hopper 43 after the slag is cut off to the inner side of the shoveling separation groove 421, so as to achieve the filtering effect of the aluminum liquid.

[0020] The slag separation outer hopper 41 is fixedly connected with a guiding vane 411. The bottom of the opening end of the main screening hopper 43 is screwed and fixed with a separable collection box 5. When the main screening hopper 43 and the slag separation outer hopper 41 are shoveled into the inner side of the electrolytic cell, the guiding vane 411 provides a guiding surface for shoveling the slag, so that the slag can more easily enter the upper end of the slag separation outer hopper 41. The separable collection box 5 is fixed to the bottom of the main screening hopper 43 by bolts. After the screening of small particles attached to the aluminum liquid is completed multiple times, the separable collection box 5 can be removed by removing the bolts, and then the small particle slag inside the separable collection box 5 can be cleaned.

[0021] Two symmetrically distributed outer isolation plates 44 are fixedly connected to the outer wall of the main screening hopper 43. The outer isolation plates 44 are used for lateral interception after the slag is shoveled; the outer isolation plates 44 are used for lateral interception after the slag enters the inner side of the slag separation outer hopper 41, so as to prevent the slag from directly detaching laterally along the slag separation outer hopper 41.

[0022] Working principle and usage process of the utility model: The linear displacement driving control 1 drives the main screening hopper 43 to shovel into the inner side of the electrolytic cell, so that the carbon slag is shoveled into the upper end of the carbon slag separation outer hopper 41 and enters the inner side of the shoveling separation tank 421. After the carbon slag is blocked by the shoveling separation tank 421, the molten aluminum on the surface of the carbon slag flows through the introduction through-hole 424 to the through-gap formed between the carbon slag separation outer hopper 41 and the main screening hopper 43. Since the main screening hopper 43 is inclined, at this time, the molten aluminum is guided into the inner side of the separated collection box 5, and the small-particle aluminum-carbon slag remaining in the molten aluminum is filtered twice through the separated collection box 5. After the filtration rate of the molten aluminum is completed, the linear displacement driving control 1 drives the main screening hopper 43 to move to the outer side of the electrolytic cell, the carbon slag separation outer hopper 41 is rotated counterclockwise by the driving control motor 2, and the carbon slag in the inner side of the shoveling separation tank 421 is discharged to the outside through the carbon slag separation outer hopper 41 under the guiding action of the lifting guiding section 423.
