Description

Technical Field

[0001] This utility model relates to the field of feeding vehicle technology, and more specifically, to a fluoride salt feeding vehicle for an electrolytic aluminum plant. Background Technology

[0002] Industrially, aluminum is produced via electrolysis. The industrial aluminum electrolysis process employs the Hall-Heroic cryolite-alumina molten salt electrolysis method. This method uses cryolite-based fluoride salts as the flux and alumina as the solute to form a multiphase electrolyte system. When a strong direct current is applied, an electrochemical reaction occurs at the electrodes within the electrolytic cell at 950℃-970℃. Fluoride salt loading vehicles are special vehicles used to fill the electrolytic cell with the solvent.

[0003] Among them, the patent with announcement number CN211308354U discloses a fluoride salt feeding vehicle for the electrolytic aluminum industry, including a chassis. The chassis includes an engine, a hydraulic torque converter, a transmission, a main drive shaft, and a drive axle. The output end of the engine is connected to the input end of the hydraulic torque converter, the output end of the hydraulic torque converter is connected to the input end of the transmission, the output end of the transmission is connected to one end of the main drive shaft, and the other end of the main drive shaft is connected to the drive shaft of the drive axle.

[0004] In use, the structure consists of a fluoride salt silo and a discharge pipe. The fluoride salt silo is fixed to the upper side of the chassis, and the discharge pipe is connected to the fluoride salt silo through a retractable hydraulic mechanism. The retractable hydraulic mechanism drives the discharge pipe to unfold and feed the electrolytic cell. However, this structure cannot achieve quantitative crushing and feeding when feeding, and the material tends to accumulate. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a fluoride salt feeding vehicle for electrolytic aluminum plants, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a fluoride salt feeding vehicle for an electrolytic aluminum plant, comprising a first vehicle body, a second vehicle body disposed on one side of the first vehicle body, and a crushing and conveying assembly disposed on the top of the second vehicle body;

[0007] The crushing and conveying assembly includes a gathering frame disposed on the top of the second vehicle body, a gathering cover covering the gathering frame, an inner lining ring disposed at the bottom of the inner wall of the gathering frame, a hollow guide frame disposed at the top of the inner lining ring, a plurality of first crushing plates distributed on the outer side of the hollow guide frame, and a guide hole through each first crushing plate, a second crushing plate disposed at the bottom of the plurality of first crushing plates, and a plurality of crushing rods disposed at the bottom of each second crushing plate, a storage box disposed on the top of the first vehicle body, a conveying auger disposed between the gathering frame and the storage box, and a discharge pipe disposed at the end of the gathering frame away from the first vehicle body, and the discharge pipe is installed on the outside of the gathering frame through a flange and connected to the gathering frame;

[0008] As can be seen, in the above technical solution, when the hollow guide frame rotates, it drives multiple first and second crushing plates to rotate. When the second crushing plate is selected, it crushes the larger material blocks in the gathering frame. When the crushing rod rotates, it performs secondary crushing on the crushed material blocks, effectively preventing the large material blocks from clogging the device. Furthermore, during the rotation of the hollow guide frame and the first crushing plate, the airflow in the gathering hood can also flow through the guide holes, allowing the airflow to flow between the gathering frame and the gathering hood, preventing the smaller materials produced by crushing from accumulating on the inner wall of the gathering frame. The crushed raw materials can also be discharged through the discharge pipe, and the material is conveyed by the rotating conveying auger, effectively preventing the crushing effect from being poor due to a large amount of material in the gathering hood.

[0009] Optionally, in a possible implementation, a motor is provided in the middle of the inner liner ring, and a protective cover is provided on the outer side of the motor. The protective cover is located at the bottom of the hollow guide frame and is rotatably connected to the hollow guide frame. The bottom end of the protective cover is embedded in the inner liner ring. A motor is provided inside the protective cover, and the output end of the motor passes through the protective cover and extends to the guide frame.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] Compared with existing technologies, the overall design of the crushing and conveying components is simple and the structure is reasonable. With the corresponding cooperation of each structure, the hollow guide frame rotates and drives multiple first crushing plates and second crushing plates to rotate. When the second crushing plate is selected, it crushes the larger material blocks in the gathering frame. When the crushing rod rotates, it performs secondary crushing on the crushed material blocks, effectively avoiding the blockage of the device due to the large material blocks.

[0012] Furthermore, during the rotation of the hollow guide frame and the first crushing plate, the airflow inside the gathering hood can flow through the guide holes, allowing the airflow to flow between the gathering frame and the gathering hood. This prevents smaller materials from accumulating on the inner wall of the gathering frame, while the crushed raw materials can be discharged through the discharge pipe and conveyed by the rotating conveying auger, effectively preventing a large amount of material inside the gathering hood from causing poor crushing results.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figures 1-6The fluoride salt feeding car of the electrolytic aluminum plant shown uses a crushing and conveying assembly on the second car body 2. When the hollow guide frame 7 rotates, it drives multiple first crushing plates 8 and second crushing plates 10 to rotate. When the second crushing plate 10 is selected, it crushes the larger material blocks in the gathering frame 3. When the crushing rod 11 rotates, it performs secondary crushing on the crushed material blocks, effectively avoiding the blockage of the device due to the large material blocks. The specific structural settings of the assembly are as follows.

[0023] The crushing and conveying assembly includes a gathering frame 3 set on the top of the second vehicle body 2, a gathering cover 4 covering the gathering frame 3, an inner lining ring 5 set at the bottom of the inner wall of the gathering frame 3, a hollow guide frame 7 set at the top of the inner lining ring 5, a plurality of first crushing plates 8 distributed on the outer side of the hollow guide frame 7, and a guide hole 9 through each first crushing plate 8, a second crushing plate 10 set at the bottom of each of the multiple first crushing plates 8, and a plurality of crushing rods 11 set at the bottom of each second crushing plate 10, a storage box 12 set on the top of the first vehicle body 1, a conveying auger 13 set between the gathering frame 3 and the storage box 12, and a discharge pipe 14 set at the end of the gathering frame 3 away from the first vehicle body 1, and the discharge pipe 14 is installed on the outside of the gathering frame 3 through a flange and connected to the gathering frame 3;

[0024] A motor 15 is provided in the middle of the inner liner ring 5. A protective cover 6 is provided on the outer side of the motor 15. The protective cover 6 is located at the bottom of the hollow guide frame 7 and is rotatably connected to the hollow guide frame 7. The bottom end of the protective cover 6 is embedded in the inner liner ring 5. The motor 15 is provided inside the protective cover 6. The output end of the motor 15 passes through the protective cover 6 and extends to the guide frame 7.

[0025] The specific working principle is as follows: Before use, first install this feeding vehicle onto the corresponding transport vehicle. Specifically, as follows... Figure 6 As shown, the first vehicle body 1 is installed on the body of the transport vehicle. The specific installation method can be selected according to the actual situation, such as using ropes for binding or using corresponding connectors for fixing. After the feeding vehicle is installed, feeding can be carried out. When feeding, the storage box 12 first stores the raw materials. The raw materials are transported to the gathering cover 4 by the conveying auger 13 and gathered by the gathering frame 3. The hollow guide frame 7 is driven to rotate by the motor 15. When the hollow guide frame 7 rotates, it drives multiple first crushing plates 8 and second crushing plates 10 to rotate. When the second crushing plate 10 selects, it crushes the larger pieces of material in the gathering frame 3. When the crushing rod 11 rotates, it performs secondary crushing on the crushed pieces, effectively avoiding the blockage of the device by large pieces of material.

[0026] Furthermore, during the rotation of the hollow guide frame 7 and the first crushing plate 8, the airflow inside the gathering hood 4 can flow through the guide hole 9, allowing the airflow to flow between the gathering frame 3 and the gathering hood 4. This prevents smaller materials generated during crushing from accumulating on the inner wall of the gathering frame 3. The crushed raw materials can also be discharged through the discharge pipe 14, and the materials are conveyed by the rotating conveying auger 13, effectively preventing the gathering hood 4 from having too much material and thus causing poor crushing effect.

[0027] Unlike existing technologies, this application discloses a fluoride salt feeding vehicle for an electrolytic aluminum plant. When the hollow guide frame 7 rotates, it drives multiple first crushing plates 8 and second crushing plates 10 to rotate. When the second crushing plate 10 is selected, it crushes larger material blocks in the gathering frame 3. When the crushing rod 11 rotates, it performs secondary crushing on the crushed material blocks, effectively avoiding blockage of the device due to large material blocks.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
