Description

Technical Field

[0001] The utility model relates to the technical field of waste heat drying of resin anode carbon blocks, in particular to a waste heat drying device for resin anode carbon blocks. Background Art

[0002] Prebaked anodes are used in the electrolytic aluminum industry, where they are used to electrolyze alumina and produce aluminum metal. Currently, the primary raw material for anodes is petroleum coke, combined with coal tar pitch, and manufactured through a series of molding and baking stages.

[0003] Moreover, in the process of preparing anodes using coal tar, the molding temperature is about 145°C. After molding, it needs to be placed in water and water-cooled to increase the strength, and then roasted for 20-30 days to prepare the finished anode resin anode carbon block. In the process of producing and forming the resin anode carbon block, a large amount of hot gas will be generated. The hot gas needs to be cooled by a cooling tower and then circulated for cooling, which will cause waste heat. After the resin anode carbon block is formed, it needs to be dried. The existing drying method uses hot air heating and drying, which causes energy waste, and the existing drying room cannot dry multiple resin anode carbon blocks at the same time. For this reason, we provide a resin anode carbon block waste heat drying device. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-8 As shown, the utility model provides a technical solution: a resin anode carbon block waste heat drying device, comprising a box body 1 and a box door 4, a heating pipe 2 is spirally arranged on the inner wall of the box body 1, the surface of the heating pipe 2 is fixed to the inner wall of the box body 1 by a fixing member 9, and both ends of the heating pipe 2 pass through the front and rear ends of the box body 1 respectively, a slide 7 is arranged at the bottom end of the interior of the box body 1, a sliding pulley 11 is arranged in the slide 7, a movable plate 8 is arranged above the pulley 11, an arc plate 10 is arranged on the surface of the movable plate 8, and the two movable plates 8 are movably connected by a connecting mechanism 12, the box door 4 is movably connected to the box body 1 through a hinge 3, the box door 4 is arranged at the front and rear ends of the box body 1, a handle 6 is provided on the box door 4, and a sealing component 5 is provided on the surface of the box door 4, and the sealing component 5 is clamped into the slide 7 when it moves downward.

[0028] The above scheme adopts the slide 7, pulley 11 and connecting mechanism 12 to connect multiple movable plates 8 and slide inside the box 1, which can facilitate the delivery of dried resin anode carbon blocks. Different numbers of movable plates 8 can be used according to the length of the box 1 in different venues to increase the drying efficiency. At the same time, the use of a sealing assembly 5 at the box door 4 can seal the inside of the box 1 when the box door 4 is closed, thereby increasing the temperature inside the box 1 during drying, which is beneficial to the drying of the resin anode carbon blocks.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, the heating pipe 2 includes an inner pipe 22 and an outer pipe 21. The outer pipe 21 is sleeved on the surface of the inner pipe 22. A cavity 23 is formed between the outer pipe 21 and the inner pipe 22, and a support block for supporting the outer pipe 21 is provided at a local position inside the cavity 23. The heating pipe 2 formed by the inner pipe 22 and the outer pipe 21 can add heat transfer oil to the cavity 23 between the inner pipe 22 and the outer pipe 21. The inner pipe 22 is connected to the waste heat pipe generated during the production of the external resin anode carbon block, and the heat transfer oil in the cavity 23 is heated by the waste heat in the inner pipe 22. At the same time, the heating pipe 2 dries the resin anode carbon block on the surface of the curved plate of the movable plate 8 inside the box 1. The waste heat in the inner pipe 22 can be increased for a second time by using the heated oil, thereby increasing the heating temperature, and the waste heat can be fully utilized by the waste heat flow rate of the inner pipe 22.

[0030] Specifically, such as Figure 6 As shown, the sealing assembly 5 includes a groove 57 opened on the box door 4, a sealing block 53 movably arranged in the groove 57, a pedal 51 fixed above the sealing block 53, a limit block 52 set on the sides of the sealing block 53 and the pedal 51, and the limit block 52 slides in the limit groove 59 opened on the side of the groove 57, and the sealing assembly 5 also includes a receiving groove 54 opened in the sealing block 53, a spring 55 set in the receiving groove 54, and a pin 56 fixed at one end of the spring 55, and the pin 56 is engaged with the slots 58 opened in the upper and lower inner walls of the groove 57. By using the pedal 51, spring 55 and pin 56 in the sealing assembly 5 and the slot 58 in the groove 57, the sealing block 53 can be moved up and down on the box door 4, and the slide 7 at the bottom end of the box body 1 can be engaged by the sealing block 53 to achieve complete sealing of the box body 1, thereby reducing the loss of heat inside the box body 1, which is beneficial to the drying of the resin anode carbon block.

[0031] Specifically, such as Figure 7As shown, the fixing member 9 includes a fixing frame 91 and a bolt 92, and the fixing frame 91 is evenly arranged on the surface of the heating pipe 2, and the heating pipe 2 is fixed to the inner wall of the box body 1 by the bolt 92. The fixing frame 91 and the bolt 92 can fix the heating pipe 2, and it is also convenient for the heating pipe 2 to be re-laid and fixed later, which is convenient for the operator to operate the heating pipe 2.

[0032] Specifically, such as Figure 8 As shown, the connecting mechanism 12 includes an adjusting tube 121, and both ends of the adjusting tube 121 are threadedly connected with threaded rods 122 with opposite threads to each other, and a connecting block 123 is fixed to the other end of the threaded rod 122, and the connecting block 123 is movably connected to a fixed block 125 through a pin shaft 124, and the fixed block 125 is fixed to the side of the movable plate 8. By using the adjusting tube 121 and the threaded rods 122 with opposite threads to each other in the connecting mechanism 12, the distance between the two threaded rods 122 can be adjusted, and then the distance between the two movable plates 8 can be adjusted, so as to realize the adjustment of the front and rear distance when drying the resin anode carbon block, and also facilitate the fixation of multiple movable plates 8.

[0033] Working principle: When in use, the operator adds the oil to be heated into the cavity 23 between the outer pipe 21 and the inner pipe 22, and connects the inner pipe 22 to the external waste heat pipe. After the connection is completed, the resin anode blocks to be dried are placed in sequence on the curved plate 10 on the surface of the movable plate 8, and the connected multiple movable plates 8 are moved to the slide inside the box body 1 through the pulley 11 at the bottom, and then the box door 4 is closed by the handle 6, and then the pedal 51 is stepped on. The pedal 51 will slide downward in the groove 57 through the side limit block 52, and the pin 56 will also squeeze the spring 55 in the storage groove 54 until the sealing block 53 is stuck in the slide 7, and the pin 56 will be stuck in the slot 58 in the groove 57 to complete the sealing of the slide, and finally start heating and drying.
