Description

Technical Field

[0001] This utility model relates to the field of petroleum coke calcination technology, specifically a calcination device for the production and processing of prebaked anodes. Background Technology

[0002] Prebaked anodes are key components of aluminum electrolysis cells. They are made from raw materials such as petroleum coke and pitch coke through multiple processes including crushing, batching, mixing, molding, and roasting. During aluminum electrolysis, they act as anodes to participate in electrochemical reactions, playing a role in conducting electricity and participating in oxidation reactions. Their quality directly affects the efficiency, energy consumption, and quality of aluminum electrolysis.

[0003] In the production and processing of prebaked anodes, the calcination device plays a crucial role, directly affecting the quality and production efficiency of the prebaked anodes. Traditional calcination devices for prebaked anode production typically use electric push rods to move a movable plate carrying the prebaked anodes. However, with the expansion of prebaked anode production scale and the increasing demands of the process, its limitations have become increasingly apparent. The installation and operation of the electric push rods are severely restricted, making it difficult to effectively achieve long-distance movement of the movable plate and meet the need for large-scale movement of the prebaked anodes within the device. Furthermore, electric push rods are relatively expensive, with complex internal structures including motors, transmission mechanisms, and other components; therefore, repairs are difficult and costly if a malfunction occurs. Utility Model Content

[0004] The purpose of this invention is to provide a calcination device for the production and processing of prebaked anodes, which solves the problem in the prior art where the installation and operation of electric push rods are greatly restricted, making it impossible to effectively achieve long-distance movement of the moving plate and meet the need for large-scale movement of prebaked anodes within the device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A calcination apparatus for the production and processing of prebaked anodes, comprising:

[0007] The base has a movable plate and a calcination box on its top, and multiple evenly distributed support legs are fixedly installed on its bottom.

[0008] A supporting mechanism, which is located on top of the movable plate and corresponds to the calcining box;

[0009] A lifting mechanism is located between the calcining box and the base and is used to drive the calcining box to move vertically.

[0010] A driving mechanism is located between the base and the movable plate and is used to drive the movable plate to move horizontally. The driving mechanism includes a steel wire rope connected to both sides of the movable plate, a sliding component, and a mounting component. The sliding component is located between the base and the movable plate and is used to limit the movement of the movable plate. The mounting component is located between the steel wire rope and the movable plate and is used to connect the steel wire rope. A positioning cylinder is fixedly installed at the bottom of the base, and the steel wire rope passes through the inside of the positioning cylinder. Protective seats are fixed on both sides of the base. Arc grooves are opened at both the upper and lower ends of the protective seats, and the steel wire rope cooperates with the two protective seats.

[0011] Preferably, the mounting assembly includes bolts screwed onto both sides of the movable plate. Flanges are fixedly installed on opposite sides of the two bolts, and bearing sleeves are installed on opposite sides of the two flanges. Both bearing sleeves are connected to both ends of the wire rope. The bolting method facilitates installation and disassembly, making it convenient to maintain the device and replace parts. The flanges and bearing sleeves not only enhance the stability of the connection but also allow the wire rope to better transmit power when under stress, reducing wear at the connection point. This ensures that the drive mechanism can stably and reliably drive the movable plate to move horizontally, improving the service life and operating efficiency of the entire device.

[0012] Preferably, heat insulation rods are fixedly installed on both sides of the top of the wire rope, and anti-slip rings are installed on the outer walls of the two heat insulation rods. The anti-slip rings on the outer walls of the heat insulation rods provide operators with better grip when operating the wire rope, making it easier to adjust and control the wire rope, and improving the safety and convenience of operation.

[0013] Preferably, the sliding assembly includes slide bars fixedly installed on both sides of the bottom of the moving plate, and the top of the base is provided with a slide groove for the slide bars to slide. The cooperation between the slide bars and the slide groove provides precise guidance and stable support for the horizontal movement of the moving plate, which can reduce the shaking and deviation of the moving plate during the movement process, and ensure that the moving plate can move smoothly and steadily along the predetermined trajectory. At the same time, the sliding friction between the slide bars and the slide groove is small, which reduces the power loss of the drive mechanism, improves the energy utilization efficiency, and makes the operation of the device more economical and efficient.

[0014] Preferably, the lifting mechanism includes a support plate fixedly installed at the bottom of the calcining chamber. Two gears are rotatably installed inside the support plate. A rack plate that meshes with the gears is fixedly installed on one side of each of the two support legs. A stepper motor is fixedly installed on one side of the support plate. The output end of the stepper motor is connected to a drive shaft. The drive shaft is fixedly connected to the axis of the two gears. A positioning component is provided between the support plate and two of the support legs to position the support plate. By driving the gears and rack plates to mesh with the stepper motor, the lifting height and speed of the calcining chamber can be precisely controlled. It has high precision and stability and can meet the position requirements of the calcining chamber for different calcining processes.

[0015] Preferably, the positioning component includes two storage slots located at the bottom of the support plate. Each storage slot contains a limiting plate. One side of each support leg has a limiting slot for inserting the limiting plate. A linkage plate is fixedly installed at the bottom of each limiting plate. A control rod is fixedly installed between the two linkage plates. The control rod allows for easy control of the extension and retraction of the limiting plate, enabling quick positioning and unlocking of the support plate and support leg. Insertion of the limiting plate into the limiting slot effectively restricts the movement of the support plate, ensuring the stability of the calcining chamber during the calcination process. The storage slots also allow the limiting plate to be stored away when not in use, preventing interference with the normal operation of the lifting mechanism and improving the overall reliability and practicality of the device.

[0016] Preferably, the bearing mechanism includes a drive motor fixedly installed inside the bearing seat, and a rotating plate is provided on the top of the bearing seat. The output end of the drive motor is fixedly connected to the rotating plate. The drive motor drives the rotating plate to rotate, which enables the prebaked anode placed on the rotating plate to continuously change its position during the calcination process, thereby achieving more uniform heating, which helps to improve the calcination quality of the prebaked anode and reduce quality problems caused by uneven heating.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] This invention uses a drive mechanism to move a movable plate horizontally. The design employs a steel wire rope, sliding assembly, and mounting assembly, avoiding the limitations of electric push rods. The steel wire rope connects to both sides of the movable plate, and under the limiting action of the sliding assembly, the movable plate can move smoothly over long distances on the top of the base. This meets the needs of large prebaked anodes moving over a wide area within the device, greatly improving the applicability and flexibility of the device. Furthermore, the drive mechanism in this device has a relatively simple structure, mainly composed of steel wire rope, sliding strip, bolts, flanges, and bearing sleeves. These components are low-cost, simple in structure, and easy to install and maintain. When some components malfunction, the steel wire rope and movable plate can be separated using bolts and bearing sleeves, making replacement and repair simpler and effectively reducing maintenance costs.

[0039] The overall working principle of this utility model is as follows:

Pass the wire rope 22 through the positioning cylinder 24 at the bottom of the base 1. Use the heat insulation rod 26 to pull the wire rope 22 to slide inside the protective seat 23. The sliding of the wire rope 22 can drive the moving plate 6 to move. Use the cooperation of the slide bar 21 and the slide groove to make the moving plate 6 move horizontally along the top of the base 1. The setting of the slide bar 21 can ensure that the moving plate 6 can move smoothly. At the same time, the heat insulation rods 26 on both sides of the top of the wire rope 22 and the anti-slip ring on its outer wall not only play a role in heat insulation, but also facilitate operation.

[0041] Pulling the control lever 38 moves the two linkage plates 37, which in turn moves the two limit plates 35, separating them from the limit grooves 36. Then, the stepper motor 34 drives the transmission shaft to rotate, which in turn drives the two gears 32 to rotate. The rotation of the gears 32 causes the support plate 31 to move vertically along the rack plate 33, which in turn moves the calcining box 4, covering the prebaked anode to be calcined. The drive motor 9 drives the rotating plate 8 to rotate, which in turn rotates the prebaked anode, ensuring that it is heated evenly within the calcining box 4.
