[0002] In the alumina industrial production system, as the last process in the production process, the roasting furnace is where the aluminum hydroxide is roasted to remove the crystal water therein and form the final sand-like alumina product. The temperature of the roasted sand-like alumina powder is 270°C to 320°C, and it needs to be cooled to below 80°C in the fluidized bed cooler of the roasting furnace before it can be transported to the alumina bin and packed for external transportation. The roasting furnace generates a large amount of heat. In industrial production, water cooling is often used to cool the roasting furnace.

[0029] When using a roasting furnace to complete a certain chemical reaction by heating the material to a temperature below its melting point, the roasting furnace will generate a large amount of heat. The roasting furnace is cooled by water cooling. The heat generated during the operation of the roasting furnace is carried away by the circulating cooling water, and then the heat of the cooling water is carried away by an external heat exchanger.
[0030] In the related art, a coil pipe is arranged outside the cold water tank. By increasing the heat exchange area, the heat dissipation efficiency is improved. However, in actual use, the coil pipe is generally fixed outside the cold water tank and does not have a disassembly function, which is inconvenient for subsequent maintenance of the coil pipe. When serious scaling occurs, the entire device needs to be replaced, increasing the cost, and there are certain limitations.
[0031] To solve the problems in the related art to a certain extent, the embodiment of the present application provides a cooling device for a roasting furnace. When in use, only the column 25 equipped with the coil pipe 26 needs to be inserted into the mounting plate 21 and fixed by the round head rod 23 to complete the installation. Conversely, disassembly can be achieved, which is more convenient and fast, improving the convenience of the device.
[0032] The present application will be described below with reference to the accompanying drawings and specific embodiments:
[0033] Combined with Figures 1 - 3 , the embodiment of the present application provides a cooling device for a roasting furnace, including a storage component 1; the storage component 1 includes: a tank body 11, with a water inlet 12 provided at its top; a drain port 13, fixedly connected to the bottom end of the tank body 11; a cooling component 2 is arranged outside the tank body 11; the cooling component 2 includes: a mounting plate 21, fixedly connected to the outside of the tank body 11; a groove body 22, opened in the mounting plate 21; a round head rod 23, slidably connected in the groove body 22; a spring 24, arranged in the round head rod 23, and both ends of the spring 24 are fixedly connected to the round head rod 23 and the mounting plate 21 respectively; a column 25, inserted into the top of the mounting plate 21, and one end of the round head rod 23 is inserted into the column 25; a coil pipe 26, fixedly connected to the outside of the column 25, and the coil pipe 26 is sleeved outside the tank body 11 and is in close contact with the outside of the tank body 11; a pipe interface 27, arranged at both ends of the coil pipe 26.
[0034] In use, after placing the tank body 11 at the designated position, the upright column 25 with the coil pipe 26 is sleeved outside the tank body 11 and pushed to insert the upright column 25 into the groove at the top of the mounting plate 21. Then, the round head rod 23 is pulled to slide outward from the groove body 22, and the spring 24 is pulled. Then, the upright column 25 is pushed again to make it penetrate deeper into the mounting plate 21. Through the resilience of the spring 24, one end of the round head rod 23 is inserted into the upright column 25, and the mounting plate 21 is pressed against the upright column 25 to limit the lateral position of the upright column 25. Subsequently, the longitudinal position of the upright column 25 is fixed by inserting the round head rod 23 into the upright column 25, and the installation is completed. The water inlet 12 at the top of the tank body 11 is connected to the drain outlet of the circulating cooling equipment for the roasting furnace, and the drain outlet 13 at the bottom of the tank body 11 is connected to the return pipe of the circulating cooling equipment for the roasting furnace. Then, one end of the coil pipe 26 at a higher position is connected to the drain outlet of the water pump through the pipe joint 27, and the other end of the coil pipe 26 at a lower position is connected to the return water pipe through another pipe joint 27. A cold water tank is arranged between the water pump and the return water pipe. After starting the water pump, the cooling water is conveyed into the coil pipe 26. By contacting the coil pipe 26 with the tank body 11, the materials in the tank body 11 are cooled. Until after long-term use, when disassembly is required, after separating the pipe joint 27 on the coil pipe 26 from the external equipment, the pipes connected to the water inlet 12 and the drain outlet 13 are removed. The round head rod 23 is pulled outward to make one end of it slide out of the upright column 25, realizing the unlocking of the upright column 25. Then, the upright column 25 is pulled to drive the coil pipe 26 to disengage from the tank body 11, and the disassembly is completed. Subsequently, after repairing, cleaning or cutting the severely blocked part of the specified water scale of the coil pipe 26, a new pipe body is replaced and welded at the original cut part. Then, repeat the above steps to install the upright column 25 and the coil pipe 26.
[0035] In some embodiments, the cooling assembly 2 further includes: a first chamfer 28, which is formed on the outer side of the round head rod 23. In use, the upright column 25 is directly inserted into the mounting plate 21. After the bottom end of the upright column 25 contacts the first chamfer 28, the round head rod 23 is pushed to slide outward in the mounting plate 21, which is convenient for installing the upright column 25.
[0036] In some embodiments, a plurality of the mounting plates 21, the groove bodies 22, the round head rods 23, the springs 24 and the upright columns 25 are provided. The plurality of upright columns 25 are respectively inserted into the plurality of mounting plates 21, and the plurality of round head rods 23 are used to fix the plurality of upright columns 25 simultaneously, improving the fixing effect.

[0038] During use, the connecting plate 35 is pushed upward to push the push rod 32. After the push rod 32 contacts the second chamfer 34, the push rod 32 pushes the round head rod 23 outward, facilitating subsequent disassembly of the upright column 25.
[0039] In some embodiments, one end of the coil pipe 26 is located at the center between two adjacent upright columns 25, facilitating the connection of the coil pipe 26 to external equipment through the pipe interface 27.
[0040] In some embodiments, the tops of the plurality of upright columns 25 are all lower than the top of the coil pipe 26, preventing the top of the upright column 25 from protruding above the coil pipe 26 and improving safety.
[0041] In some embodiments, a plane is provided inside the coil pipe 26 to increase the contact area between the coil pipe 26 and the tank body 11 and improve the heat dissipation effect.
[0042] In some embodiments, the push rod 32 and the limiting block 33 are a group, and multiple groups are provided on the mounting seat 31, enabling the connecting plate 35 to simultaneously push multiple push rods 32, and enabling the multiple push rods 32 to simultaneously push multiple round head rods 23 to slide outward, facilitating the disassembly of the upright column 25.
