Description

Technical Field

[0001] This utility model relates to the technical field of electrolyte cleaning devices, and in particular to a spray-type high-efficiency cleaning device for aluminum residual electrodes of electrolytes. Background Technology

[0002] During the aluminum electrolysis production process, a large amount of electrolyte will adhere to the surface of the residual electrode, which needs to be cleaned to achieve resource recycling. Existing cleaning technologies are mainly divided into two categories: one is mechanical cleaning equipment, such as automatic cleaning equipment, which removes the electrolyte from the surface of the residual electrode by mechanical means such as impact hammers, vibrating units, and pneumatic picks; the other is immersion cleaning.

[0003] When electrolyte cleaning devices are in use, the existing technology has the following significant drawbacks. First, mechanical cleaning equipment such as impact hammers and vibratory units are prone to scratching the surface of the residual electrode during the cleaning process, affecting product quality. Second, traditional immersion cleaning is inefficient, and the accumulation of fragments can easily form cleaning dead corners, making it difficult to guarantee cleaning quality. In addition, spray cleaning devices lack a three-dimensional rinsing design for electrolyte aluminum residual electrode fragments, resulting in limited cleaning effect.

[0004] Therefore, to address the problem of inconvenient efficient cleaning of electrolyte aluminum electrode fragments in continuous operation scenarios, a spray-type high-efficiency cleaning device for electrolyte aluminum electrode fragments can be designed. When the device is in use, the operator places the electrolyte aluminum electrode fragments to be cleaned into the cleaning cylinder. The fragments directly enter the rotatable filter cylinder cavity, while cleaning fluid is simultaneously drawn and delivered to the spray pipe. The densely distributed spray holes on the pipe face the top area of ​​the filter cylinder, forming a uniform water curtain covering the entire filter cylinder cavity, continuously rinsing the electrolyte fragments from top to bottom. Simultaneously, the filter cylinder is driven to rotate at a specific speed. During rotation, a triple action occurs: under the combined action of friction and centrifugal force on the inner wall of the filter cylinder, the fragments spiral upwards along the cylinder wall and then fall downwards, forming a tumbling motion, fully exposing all surfaces and cleaning the inner wall of the cylinder. The flexible protrusions intermittently collide with the rotating fragments, enhancing cleaning power while avoiding mechanical damage to the materials. Wastewater carrying impurities seeps out through the pores around the filter cylinder, entering the annular space formed by the inner cavity of the cleaning cylinder and the outer wall of the filter cylinder. In summary, the inclined layout shortens the material transport path, the flexible protrusion design ensures cleaning power while preventing scratches on the material surface, and the spray pressure and filter cylinder rotation speed are adjustable to adapt to the cleaning needs of fragments of different particle sizes, thus improving the product qualification rate. This device innovatively combines fluid mechanics and mechanical power, using the centrifugal tumbling effect generated by the rotating filter cylinder combined with the three-dimensional rinsing of the spray pipe to achieve 360° cleaning without dead angles, improving efficiency compared to traditional immersion cleaning. This allows for automated and efficient cleaning of electrolyte aluminum electrode fragments. Utility Model Content

The fragments directly enter the inner cavity of the rotatable filter cylinder, and cleaning fluid is simultaneously drawn in and delivered to the spray pipe.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Example 1

[0027] Please see Figure 1 and Figure 4 This utility model provides an embodiment: a spray-type high-efficiency cleaning device for residual aluminum electrodes of electrolyte, including an inclined support 1, a cleaning cylinder 2 fixedly installed inside the inclined support 1, the cleaning cylinder 2 being arranged at an inclined angle, and a filter cylinder 3. The inner cavity of the cleaning cylinder 2 is provided with a rotatable filter cylinder 3, the inclined angle of which is the same as that of the cleaning cylinder 2. A spray pipe 4 extending in the inclined direction is fixedly installed on the top side of the inner cavity of the cleaning cylinder 2. The spray pipe 4 is located above the filter cylinder 3, and its spray holes are directly facing the top area of ​​the filter cylinder 3. The spray pipe 4 and the cleaning cylinder 2 maintain the same inclined angle. Multiple sets of holes are opened through the outer peripheral surface of the cleaning cylinder 2, and multiple sets of flexible protrusions are fixedly installed on the inner wall of its inner cavity.

[0028] Please see Figure 5 and Figure 6 A discharge pipe 5 is installed through the bottom wall of the cleaning cylinder 2. The discharge pipe 5 has a built-in control valve. A discharge port is opened through the bottom wall of the cleaning cylinder 2, and the size of the discharge port is adapted to the discharge pipe 5. The upper end face of the discharge pipe 5 forms a sealing interference fit with the bottom wall of the filter cylinder 3. After cleaning is completed, the control valve built into the discharge pipe 5 is opened. When the discharge port at the bottom of the filter cylinder 3 is rotated to coincide with the upper end of the discharge pipe 5, the cleaned electrolyte fragments are discharged along the discharge pipe under the action of gravity. 5. The bottom of the inner cavity of the cleaning cylinder 2 forms a stepped cavity structure. The inner wall of the stepped cavity and the outer wall of the bottom end of the filter cylinder 3 form a sealed interference fit. A drain pipe 6 is installed through the bottom wall of the bottom end of the cleaning cylinder 2. The upper end of the drain pipe 6 is connected through the fracture of the stepped cavity. The bottom of the inner cavity of the cleaning cylinder 2 is designed as a stepped cavity structure. The seeping sewage collects along the inclined surface of the stepped cavity to the fracture and is discharged through the drain pipe 6, which is connected to it, so as to achieve the initial separation of sewage and cleaning liquid.

[0029] Please see Figure 5 and Figure 6A feed cylinder 7 is installed through the top of the filter cylinder 3, and the upper end of the feed cylinder 7 extends to the outside of the top of the cleaning cylinder 2. The outer wall of the feed cylinder 7 is rotatably connected to the inner wall of the top through hole of the cleaning cylinder 2. A drive motor 8 is fixedly installed on the outer wall of the bottom of the cleaning cylinder 2, and the output end of the drive motor 8 is fixedly connected to the outer wall of the bottom of the filter cylinder 3. The operator puts the electrolyte aluminum electrode fragments to be cleaned into the cleaning cylinder 2 through the feed cylinder 7. The fragments directly enter the inner cavity of the rotatable filter cylinder 3. The feed cylinder 7 and the top through hole of the cleaning cylinder 2 are rotatably connected to ensure the stability of the feed channel when the filter cylinder 3 rotates. The drive motor 8 is started to drive the filter cylinder 3 to rotate at a specific speed. A support frame 9 is fixedly installed on one side of the bottom of the cleaning cylinder 2, and a water storage tank 10 is fixedly installed on the top of the support frame 9. A water injection pipe is installed through the water tank 10. The bottom outer wall of the water tank 10 is connected to the bottom end of the spray pipe 4 through a pipe. A water injection pipe is installed on the top of the water tank 10 to replenish the cleaning solution. A water pump 11 is fixedly installed on one side of the top of the support frame 9. A connecting pipe 12 is installed through the bottom outer wall of the water tank 10. The outlet end of the connecting pipe 12 is connected to the inlet end of the water pump 11. The outlet end of the water pump 11 is connected to the bottom end of the spray pipe 4. When the water pump 11 is started synchronously, the cleaning solution in the water tank 10 is drawn to the water pump 11 through the connecting pipe 12, and then transported to the spray pipe 4 through the pipe. The spray pipe 4 is arranged along the inclined direction of the cleaning cylinder 2. The densely distributed spray holes on it face the top area of ​​the filter cylinder 3, forming a uniform water curtain covering the entire inner cavity of the filter cylinder 3, and continuously rinsing the electrolyte fragments from top to bottom.

[0030] When the electrolyte cleaning device is in use, the spray-type high-efficiency cleaning device for aluminum residual electrolyte electrodes achieves automated and efficient cleaning through the collaboration of multiple components. The specific process is as follows: In the feeding stage, the operator puts the fragments of the aluminum residual electrolyte electrodes to be cleaned into the cleaning cylinder 2 through the feeding cylinder 7. The fragments directly enter the inner cavity of the rotatable filter cylinder 3. The feeding cylinder 7 and the top through hole of the cleaning cylinder 2 adopt a rotating connection design to ensure the stability of the feeding channel when the filter cylinder 3 rotates.

[0031] The water pump 11 is started simultaneously. The cleaning solution in the water storage tank 10 is drawn into the water pump 11 through the connecting pipe 12, and then transported to the spray pipe 4 through the pipeline. The spray pipe 4 is arranged along the inclined direction of the cleaning cylinder 2. The densely distributed spray holes on it are directly facing the top area of ​​the filter cylinder 3, forming a uniform water curtain covering the entire inner cavity of the filter cylinder 3, and continuously rinsing the electrolyte fragments from top to bottom.

[0032] The drive motor 8 is fixedly connected to the bottom outer wall of the filter cylinder 3 via the output shaft. When the drive motor 8 is started, the filter cylinder 3 is rotated at a specific speed. During the rotation, a triple action is generated. Under the dual action of friction and centrifugal force on the inner wall of the filter cylinder 3, the fragments spiral up and fall down along the cylinder wall, forming a tumbling motion, which fully exposes each surface. The flexible protrusions set on the inner wall of the cleaning cylinder 2 intermittently collide with the rotating fragments, which not only enhances the cleaning force but also avoids mechanical damage to the material.

[0033] The wastewater generated during cleaning carries impurities and seeps out through the holes around the filter cylinder 3, entering the annular space formed by the inner cavity of the cleaning cylinder 2 and the outer wall of the filter cylinder 3. The bottom of the inner cavity of the cleaning cylinder 2 is designed as a stepped cavity structure. The seeping wastewater collects along the inclined surface of the stepped cavity to the fault and is discharged through the drain pipe 6 that is connected to it, thus achieving the initial separation of wastewater and cleaning liquid.

[0034] After cleaning is completed, the control valve built into the discharge pipe 5 is opened. At this time, the drive motor 8 continues to finely adjust the angle of the filter cylinder 3. When the discharge port at the bottom of the filter cylinder 3 rotates to coincide with the upper port of the discharge pipe 5, the cleaned electrolyte fragments slide down and are discharged under the action of gravity. The interference fit design between the discharge pipe 5 and the bottom wall of the filter cylinder 3 ensures that the discharge process is sealed and leak-free. A water injection pipe is set at the top of the water storage tank 10 to replenish the cleaning solution.

[0035] In summary, the integrated feeding, cleaning, discharging, and sewage discharge process is fully automated, allowing a single unit to complete continuous operations, reducing manual intervention and labor intensity. The stepped cavity structure enables solid-liquid separation, while the clean fragments in the collection chamber 14 can be directly remelted, improving raw material utilization. The inclined layout shortens the material conveying path, and the drive motor 8 and water pump 11 are integrated at the bottom of the cleaning cylinder 2, reducing the overall footprint compared to similar equipment and facilitating large-scale deployment. The flexible protrusion design ensures cleaning power while avoiding scratches on the material surface. The spray pressure and the rotation speed of the filter cylinder 3 are adjustable to meet the cleaning needs of fragments with different particle sizes, thereby improving the product qualification rate.

[0036] This device achieves 360° cleaning without dead angles by combining the centrifugal tumbling effect generated by the rotating filter cylinder 3 with the three-dimensional rinsing of the spray pipe 4 through an innovative combination of fluid mechanics and mechanical power, which improves the efficiency compared with traditional immersion cleaning.

[0037] Example 2

[0038] Please see Figure 2 and Figure 3 The difference from Example 1 is that a collection bin 14 is arranged below the discharge pipe 5, and a collection tank 13 is arranged below the sewage pipe 6.

[0039] The seeping sewage collects along the inclined surface of the stepped cavity to the fault, and is discharged into the lower collection tank 13 through the sewage pipe 6 that is connected to it, so as to achieve the initial separation of sewage and cleaning liquid. In addition, when the discharge port at the bottom of the filter cylinder 3 is rotated to coincide with the upper port of the discharge pipe 5, the cleaned electrolyte fragments slide down the discharge pipe 5 to the lower collection chamber 14 under the action of gravity.

[0040] Through the above steps, when the electrolyte cleaning device is in use, the operator puts the electrolyte aluminum electrode fragments to be cleaned into the cleaning cylinder 2. The fragments directly enter the inner cavity of the rotatable filter cylinder 3, and the cleaning liquid is simultaneously drawn in and delivered to the spray pipe 4. The densely distributed spray holes on the spray pipe 4 face the top area of ​​the filter cylinder 3, forming a uniform water curtain covering the entire inner cavity of the filter cylinder 3, continuously rinsing the electrolyte fragments from top to bottom. At the same time, the filter cylinder 3 is driven to rotate at a specific speed. During the rotation, a triple action is generated. Under the dual action of friction and centrifugal force on the inner wall of the filter cylinder 3, the fragments spiral upward along the cylinder wall and then fall, forming a tumbling motion, fully exposing all surfaces. The flexible protrusions on the inner wall of the cleaning cylinder 2 intermittently collide with the rotating fragments, which enhances the cleaning effect. The cleaning process is effective while avoiding mechanical damage to the materials. The wastewater generated during cleaning, carrying impurities, seeps out through the holes around the filter cylinder 3 and enters the annular space formed by the inner cavity of the cleaning cylinder 2 and the outer wall of the filter cylinder 3. In summary, the inclined layout shortens the material conveying path, and the flexible protrusion design ensures cleaning power while avoiding scratches on the material surface. The spray pressure and the rotation speed of the filter cylinder 3 are adjustable to adapt to the cleaning needs of fragments of different particle sizes, thereby improving the product qualification rate. This device achieves 360° cleaning without dead angles by combining the centrifugal tumbling effect generated by the rotating filter cylinder 3 with the three-dimensional rinsing of the spray pipe 4 through an innovative combination of fluid mechanics and mechanical power. This improves the efficiency compared to traditional immersion cleaning, thus enabling automated and efficient cleaning of electrolyte aluminum electrode fragments.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
