Description

Technical Field

[0001] This utility model relates to the field of prebaked aluminum electrolytic cell technology, specifically to a fluoride salt batching device for a prebaked aluminum electrolytic cell. Background Technology

[0002] The fluoride salt batching device for prebaked aluminum electrolytic cells is a key auxiliary system in aluminum electrolysis production. It is responsible for continuously and accurately adding the required fluoride salt mixture to the electrolytic cell to maintain the ideal composition and molecular ratio of the electrolyte. Existing batching devices typically use mixing devices such as V-shaped mixers. When the mixed raw materials are taken out, they are prone to clogging the outlet after absorbing moisture, which often requires manual unblocking and reduces the efficiency of batching. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a prebaked aluminum electrolytic cell fluoride salt batching device, which solves the problem that the mixing devices used in existing batching devices are usually V-shaped mixers or similar mixing devices. When the mixed raw materials are taken out, they are prone to clogging the outlet after absorbing moisture, which often requires manual unblocking and reduces the efficiency of batching.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a prebaked aluminum electrolytic cell fluoride salt batching device, comprising a mounting bracket, a hydraulic cylinder mounted on the top of the mounting bracket, guide rods on both sides of the hydraulic cylinder, a mounting plate connected above the hydraulic cylinder and the guide rods, a storage bin mounted on the top of the mounting plate, a drive motor one mounted on the outside of the mounting bracket, and a mixing bin connected to the output end of the drive motor one, a drive motor two mounted at the bottom of the mixing bin, and a stirring rod connected to the output end of the drive motor two, a drive motor three mounted on the outside of the mixing bin, and a feeding rod connected to the output end of the drive motor three, a discharge port mounted at the bottom of the mixing bin, and a solenoid valve mounted on the discharge port, a servo motor mounted on the top of the mixing bin, and a transmission rod connected to the output end of the servo motor, a weighing hopper mounted on the transmission rod, and a weighing scale mounted at the bottom of the weighing hopper.

[0005] The beneficial effects of this utility model are as follows: after mixing is completed, drive motor one and drive motor two are turned off, drive motor three continues to run, the mixing hopper remains tilted, the solenoid valve is opened and the raw material is discharged through the discharge port, drive motor three drives the material feeding rod to rotate to avoid the raw material from being blocked at the discharge port, thus completing the batching. The above method can ensure the speed of material discharge.

[0006] To facilitate the rotation of the stirring rod:

[0007] As a further improvement to the above technical solution: the second drive motor and the stirring rod are driven by a reducer.

[0008] The beneficial effect of this improvement is that the speed reducer can ensure the stability of the stirring rod when the drive motor drives it to rotate.

[0009] To facilitate the rotation of the feeding rod:

[0010] As a further improvement to the above technical solution: a bearing is installed at the connection between the feeding rod and the mixing bin.

[0011] The beneficial effects of this improvement are: the bearing can effectively reduce the friction when the feed lever rotates, making the rotation of the feed lever more stable.

[0012] To facilitate the rotation of the weighing hopper:

[0013] As a further improvement to the above technical solution: wear-resistant blocks are provided in the mixing bin near the weighing hopper.

[0014] As a further improvement to the above technical solution: the two ends of the weighing hopper are arranged in an arc shape.

[0015] The beneficial effects of this improvement are: the servo motor drives the weighing hopper to rotate through the transmission rod, and the arc-shaped arrangement between the servo motor and the wear-resistant block makes the rotation of the weighing hopper more reliable and stable.

[0016] To facilitate the installation and lifting of the horizontal plate:

[0017] As a further improvement to the above technical solution: the mounting plate and the mounting bracket are arranged in parallel to each other.

[0018] The beneficial effects of this improvement are: the hydraulic cylinder drives the mounting plate to rise and fall along the guide rod, and the parallel arrangement of the two rods allows the hydraulic cylinder to push the mounting plate to rise and fall smoothly.

[0019] In order to control the discharge of raw materials:

[0020] As a further improvement to the above technical solution: a gate valve is installed at the bottom of the storage silo.

[0021] The beneficial effects of this improvement are: the opening and closing of the storage bin can be controlled by the slide valve, making it easier for raw materials to enter the weighing hopper.

[0022] Convenient for raw material input:

[0023] As a further improvement to the above technical solution: the mounting plate and the mounting bracket are connected by a hydraulic cylinder to form a lifting and mounting structure.

[0024] The beneficial effects of this improvement are: the lifting and lowering of the mounting plate driven by the hydraulic cylinder can reduce the distance between the storage bin and the weighing hopper, and can reduce the occurrence of raw materials splashing due to collision.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0032] like Figure 1-5As shown, a prebaked aluminum electrolytic cell fluoride salt batching device includes a mounting bracket 1. A hydraulic cylinder 11 is mounted on top of the mounting bracket 1, and guide rods 12 are provided on both sides of the hydraulic cylinder 11. A mounting horizontal plate 13 is connected above the hydraulic cylinder 11 and the guide rods 12. A storage bin 14 is mounted on the top of the mounting horizontal plate 13. A drive motor 15 is mounted on the outside of the mounting bracket 1, and the output end of the drive motor 15 is connected to a mixing bin 2. A drive motor 21 is mounted on the bottom of the mixing bin 2, and the output end of the drive motor 21 is connected to a stirring rod 22. A drive motor 23 is mounted on the outside of the mixing bin 2. The output end of the mixing chamber 2 is connected to a feeding rod 24. A discharge port 25 is installed at the bottom of the mixing chamber 2, and a solenoid valve 26 is installed on the discharge port 25. A servo motor 3 is installed at the top of the mixing chamber 2, and a transmission rod 31 is connected to the output end of the servo motor 3. A weighing hopper 32 is installed on the transmission rod 31, and a weighing scale 33 is installed at the bottom of the weighing hopper 32. After mixing, drive motor 15 and drive motor 21 are turned off, while drive motor 33 continues to operate. The mixing chamber 2 remains tilted. When solenoid valve 26 is opened, the raw material is discharged through the discharge port 25. Drive motor 323 drives the feeding rod 24 to rotate, preventing the raw material from clogging the discharge port 25, thus completing the batching process. The above method ensures the discharge speed. The drive motor 21 and the stirring rod 22 are connected by a reducer, which ensures the stability of the drive motor 21 when driving the stirring rod 22. A bearing is installed at the connection between the feeding rod 24 and the mixing bin 2, effectively reducing friction during rotation and making the rotation more stable. Wear-resistant blocks are provided near the weighing hopper 32 in the mixing bin 2. The two ends of the weighing hopper 32 are arc-shaped. The servo motor 3 drives the weighing hopper 32 to rotate via the transmission rod 31. The arc-shaped design and the wear-resistant blocks ensure stable rotation of the weighing hopper 32. The movement is more reliable and stable. The mounting plate 13 and the mounting bracket 1 are arranged in parallel to each other. The hydraulic cylinder 11 drives the mounting plate 13 to rise and fall along the guide rod 12. The parallel arrangement allows the hydraulic cylinder 11 to push the mounting plate 13 to rise and fall smoothly. The bottom of the storage bin 14 is equipped with a slide valve, which can control the opening and closing of the storage bin 14 to facilitate the entry of raw materials into the weighing hopper 32. The mounting plate 13 and the mounting bracket 1 are connected by the hydraulic cylinder 11 to form a lifting and mounting structure. The lifting and lowering of the mounting plate 13 by the hydraulic cylinder 11 can reduce the distance between the storage bin 14 and the weighing hopper 32, and reduce the phenomenon of raw materials splashing due to collision.

[0033] The working principle of this utility model is as follows: When using this device, the hydraulic cylinder 11 drives the mounting plate 13 to rise and fall along the guide rod 12, and the storage bin 14 reaches above the weighing hopper 32. The slide valve at the bottom of the storage bin 14 is opened, and the raw material enters the weighing hopper 32. The weighing scale 33 weighs the raw material in the weighing hopper 32. After weighing, the hydraulic cylinder 11 pushes the mounting plate 13 to rise and reset. The servo motor 3 drives the weighing hopper 32 to rotate through the transmission rod 31. Through the rotation of the weighing hopper 32, the raw material enters the mixing bin 2 under the action of gravity. The weighing hopper 32 is in a flipped state. At the top of the mixing hopper 2, drive motor 21 and drive motor 3 23 respectively drive the stirring rod 22 and the feeding rod 24 to rotate and mix the raw materials. Drive motor 15 drives the mixing hopper 2 to swing. In this way, the raw materials are quickly and evenly mixed. After the mixing is completed, drive motor 15 and drive motor 21 are turned off, while drive motor 3 23 continues to run. The mixing hopper 2 remains tilted. The solenoid valve 26 is opened and the raw materials are discharged through the discharge port 25. Drive motor 3 23 drives the feeding rod 24 to rotate to prevent the raw materials from blocking the discharge port 25, thus completing the batching. The above method can ensure the speed of discharge.
