Description

Technical Field

[0001] This utility model relates to the field of red mud treatment technology, specifically a red mud roasting reactor. Background Technology

[0002] Alumina production generates a large amount of red mud, and its treatment and comprehensive utilization are key issues of concern in the industry. Roasting is one of the crucial steps in red mud treatment. Traditional red mud roasting equipment mostly adopts a single-furnace, single-stage heating mode. This type of equipment can only heat one batch of red mud at a time. With the continuous increase in red mud production and the increasing demands for processing efficiency, the single-furnace, single-stage heating method is difficult to meet the needs of large-scale production, resulting in low equipment utilization and low production efficiency. Furthermore, its heating method often uses indirect heating, resulting in significant heat loss during the transfer process. This prevents the red mud from fully absorbing heat during roasting, leading to energy waste and increased production costs. Utility Model Content

[0003] The purpose of this invention is to provide a red mud roasting reactor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A red mud roasting reactor includes a heat collection box. A sealing plate is snapped into the opening of the heat collection box. A holding component for holding materials is provided on the sealing plate. A receiving plate is fixedly connected to the surface of the heat collection box. An electromagnetic component for heating the holding component is provided inside the heat collection box along with the receiving plate. The holding component includes a feed inlet, a cover plate, a sealing ring, a tank body, a straightening plate, a positioning head, a positioning block, a positioning groove, and a sliding groove. A sliding groove is provided on the sealing plate. Three evenly distributed straightening plates are fixedly connected to the lower surface of the sealing plate.

[0005] Furthermore, the sealing plate is slidably connected to the tank body via a straightening plate and a sliding groove. A cover plate is provided on the upper end of the tank body via a flange, and a sealing ring is provided between the cover plate and the tank body. A feed inlet is fixedly connected to the upper end of the cover plate.

[0006] Furthermore, a positioning block is fixedly connected inside the heat collection box, and a positioning groove is opened on the upper surface of the positioning block. A positioning head is fixedly connected to the lower end of the tank, and the positioning head is snapped onto the positioning block through the positioning groove.

[0007] Furthermore, the electromagnetic component includes an electromagnetic induction generator, a negative terminal connector, a negative terminal connecting plate, a positive terminal connector, and a positive terminal connecting plate. The electromagnetic induction generator is installed inside the heat collection box and is sleeved on the surface of the tank.

[0008] Furthermore, a control panel is provided on the surface of the receiving plate, and a negative terminal is fixedly connected to the surface of the electromagnetic induction generator. A negative terminal connecting plate is fixedly connected to one end of the negative terminal, and the negative terminal connecting plate is electrically connected to the control panel.

[0009] Furthermore, a positive terminal is fixedly connected to the surface of the electromagnetic induction generator, and a positive terminal connection plate is fixedly connected to one end of the positive terminal, which is electrically connected to the control panel.

[0010] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: The design of the heat collection box and receiving plate in this red mud roasting reactor allows for the installation of multiple electromagnetic components within the same box. By arranging multiple electromagnetic induction generators within the heat collection box, multiple tanks can be heated simultaneously, significantly improving the processing efficiency of red mud roasting and meeting the needs of large-scale production. This multi-component parallel heating mode breaks through the limitations of traditional single-furnace single-stage heating, effectively improving equipment utilization and production efficiency. The core of the red mud roasting reactor consists of a heat collection box, a sealing plate, a container assembly, and electromagnetic components.

[0011] The combination of the heat collection box and the sealing plate forms a relatively closed heating space. The sealing ring on the sealing plate further enhances the sealing performance and effectively reduces heat loss. At the same time, the electromagnetic induction generator is sleeved on the surface of the tank and directly heats the tank, reducing heat loss during the transfer process. This structural design allows heat to be effectively concentrated in the tank, ensuring that the red mud can fully absorb heat during the roasting process, improving heat utilization efficiency, reducing energy consumption, and effectively storing the lost heat in the tank, which can further reduce cost consumption. In the container assembly, the tank is slidably connected to the sealing plate via a straightening plate and a sliding groove. The snap-fit ​​design between the positioning head and the positioning groove makes the tank easy to install and remove, and the positioning is precise. Once a tank has finished heating, it can be quickly removed from the heat collection box and replaced with a new tank to be heated. The entire process does not require stopping the overall heating operation. This design effectively avoids equipment downtime caused by tank replacement, ensures production continuity, improves production efficiency, and also reduces energy consumption and equipment wear caused by equipment start-up and shutdown.

[0016] In this embodiment, the electromagnetic assembly includes an electromagnetic induction generator 8, a negative terminal connector 9, a negative terminal connecting plate 10, a positive terminal connector 11, and a positive terminal connecting plate 12. The electromagnetic induction generator 8 is housed inside the heat collection box 2 and is sleeved on the surface of the tank body 7. A control panel 18 is mounted on the surface of the receiving plate 3. The negative terminal connector 9 is fixedly connected to the surface of the electromagnetic induction generator 8, and one end of the negative terminal connector 9 is fixedly connected to the negative terminal connecting plate 10.

[0017] Open the cover plate 5 and feed the red mud material into the tank 7 through the feed inlet 4. After feeding, tightly connect the cover plate 5 to the tank 7 through the flange to ensure that the sealing ring 6 is well sealed. Then, slide the tank 7 containing the material into the heat collection box 2 along the sliding groove 17 on the sealing plate 1. Under the guidance of the straightening plate 13, the tank 7 slides smoothly. When the tank 7 slides to the appropriate position inside the heat collection box 2, the positioning head 14 at the lower end of the tank 7 accurately engages in the positioning groove 16 on the positioning block 15, completing the installation and positioning of the tank 7. After the tank 7 is installed, the operator starts the electromagnetic component through the control panel 18 on the surface of the receiving plate 3. The control panel 18 sends an electrical signal to the electromagnetic induction generator 8. After the electromagnetic induction generator 8 is powered on, it generates an alternating magnetic field. This magnetic field acts on the tank 7, causing the tank 7 to generate an induced current, which in turn generates heat to heat and roast the red mud inside the tank 7. Since the heat collection box 2 and the sealing plate 1 form a closed space and the sealing ring 6 is effectively sealed, the heat... The amount of material is confined within the box, while the electromagnetic induction generator 8 directly heats the tank 7, reducing heat transfer loss and improving heat utilization efficiency. Multiple electromagnetic induction generators 8 can operate simultaneously within the same heat collection box 2, heating multiple tanks 7 in parallel, significantly improving the processing efficiency of red mud roasting. Once a tank 7 has finished heating, it is slid outwards from the heat collection box 2 along the sliding groove 17. Due to the cooperation between the positioning head 14 and the positioning groove 16, the tank 7 can be easily removed without affecting other tanks 7 that are being heated. After removal, a new tank 7 containing red mud material is installed into the heat collection box 2 according to the above installation steps. The entire replacement process does not require stopping the heating of other tanks 7, ensuring production continuity, improving production efficiency, and reducing energy consumption and equipment wear caused by frequent equipment start-ups and shutdowns. Moreover, the small amount of heat lost during heating is effectively stored within the tank 7, further reducing cost consumption.

[0018] The design of the heat collection box 2 and the receiving plate 3 in this red mud roasting reactor allows for the installation of multiple electromagnetic components within the same box. By arranging multiple electromagnetic induction generators 8 within the heat collection box 2, multiple tanks 7 can be heated simultaneously, significantly improving the processing efficiency of red mud roasting and meeting the needs of large-scale production. This multi-component parallel heating mode breaks the limitations of traditional single-furnace single-heating, effectively improving equipment utilization and production efficiency. The cooperation between the heat collection box 2 and the sealing plate 1 forms a relatively enclosed heating space. The sealing ring 6 on the sealing plate 1 further enhances the sealing performance, effectively reducing heat loss. Simultaneously, the electromagnetic induction generators 8 are fitted onto the surface of the tanks 7, directly heating them and reducing heat loss during transfer. This structural design allows heat to be effectively concentrated within the box, ensuring that the red mud fully absorbs heat during roasting, improving heat utilization efficiency, reducing energy consumption, and minimizing heat loss. Heat is effectively stored in the tank 7, which can further reduce cost consumption. In the holding components, the tank 7 is slidably connected to the sealing plate 1 via the straightening plate 13 and the sliding groove 17. The snap-fit ​​design of the positioning head 14 and the positioning groove 16 makes the tank 7 easy to install and disassemble and the positioning precise. When a tank 7 has finished heating, it can be quickly removed from the heat collection box 2 and replaced with a new tank 7 to be heated. The whole process does not require stopping the overall heating operation. This design effectively avoids equipment downtime caused by the replacement of tank 7, ensures the continuity of production, improves production efficiency, and also reduces energy consumption and equipment wear caused by equipment start-up and shutdown.
