Technical Field
[0001] The utility model relates to the technical field of anode carbon blocks, in particular to a waste heat recovery device for anode carbon blocks. Background Art
[0002] Anode carbon block refers to a carbon block produced with petroleum coke and asphalt coke as aggregate and coal tar as binder. It is used as anode material for prebaked aluminum electrolytic cells. This carbon block has been baked and has a stable geometric shape, so it is also called prebaked anode carbon block, and is customarily called carbon anode for aluminum electrolysis.
[0003] In the process of anode carbon block production, a drying kiln is required. The temperature of the drying kiln is extremely high. The formed carbon blocks will still have a high temperature after coming out. These temperatures will also cause the factory building to rise. In winter, it will be impossible to heat the outside. In summer, the factory building temperature will be too high, and thermal energy resources cannot be used reasonably. Therefore, these temperatures need to be collected and reused. We provide a waste heat recovery device for anode carbon blocks to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figure 1-6 As shown, the utility model provides a technical solution: a waste heat recovery device for anode carbon blocks, comprising a box body 1, a circulating water pipe 2 is arranged at the bottom end of the box body 1, a cooling fan 12 is fixed to the inner wall side of the box body 1, a storage tank 4 is arranged above the box body 1, a supercharger 5 is arranged above the storage tank 4, and a gas pipeline 3 is connected between the storage tank 4 and the supercharger 5. The supercharger 5 can also pressurize and transmit the gas in the storage tank 4 to avoid temperature loss during transmission. A connecting hole 10 is opened above the box body 1, and the gas pipeline 3 above the storage tank 4 passes through the connecting block and is connected to the inside of the box body 1. The inside of the box 1 A filter plate 13 is provided, and the filter plate 13 is located below the gas pipeline 3. A groove 8 is provided on the surface of the box body 1. A baffle 7 is provided at the groove 8, and the baffle 7 is movably connected to the box body 1 through a pin shaft. The number of the baffles 7 is five, and they are evenly arranged from top to bottom. Two baffles 7 are movably connected through a pin shaft. By providing the gas pipeline 3, the storage tank 4 and the circulating water pipe 2, the heat generated by the carbon anode block can be collected. At the same time, under the action of the heat dissipation fan 12, the cooling of the carbon anode block can be accelerated, and the gas and water with temperature can be collected. The collected heat energy can also be reused to avoid waste of resources.
[0026] Specifically, Figure 3 , Figure 5 and Figure 6 As shown, a feed cart 15 is arranged inside the box body 1, and connecting hooks 16 for connecting another feed cart 15 are arranged at the front and rear ends of the feed cart 15, and rollers 18 are arranged at the bottom end of the feed cart 15, and the rollers 18 are evenly distributed at the bottom end of the feed cart 15, and a limit block 9 is arranged at the bottom end of the box body 1, and the limit block 9 matches the limit groove 17 opened on both sides of the feed cart 15. Multiple groups of feed carts 15 are used and connected through the connecting hooks 16, so that the baffle 7 can be lowered when a single feed cart 15 enters the box body 1, thereby avoiding the loss of a large amount of heat inside the box body 1, and continuous operation and transportation can be achieved at the same time.
[0027] Specifically, Figure 3 and Figure 4As shown, a slide groove 11 is provided at the top of the inner part of the box body 1, and a slider 14 is provided on the slide groove 11. The slider 14 is fixedly connected to the filter plate 13. The slide groove 11 is provided on the top of the box body 1 and the slider 14 is used to drive the filter plate 13 to slide back and forth, so that the later operating personnel can remove the filter plate 13 from the connection port through the slide groove 11 and the slider 14, so as to facilitate the cleaning of the gas pipeline 3 at the connection port and avoid the pipeline being blocked due to long-term use.
[0028] Working principle: After the carbon anode blocks pass through the drying kiln, the carbon anode blocks themselves will still carry heat. The hot carbon anode blocks are sent to the inside of the box 1 through the groove 8 by the feeding cart 15. When the feeding cart 15 reaches the groove 8, the carbon anode blocks on the surface will hit multiple baffles 7 connected by pins. After all the carbon anode blocks enter the inside of the box 1, the baffles 7 will return to their original positions. The fan inside the box 1 will cool down the carbon anode blocks on the surface of the feeding cart 15 again, and the generated gas will pass through the filter plate 13 and the gas pipeline 3 to the storage tank 4. After the circulating water pipe 2 arranged at the bottom of the box 1 is preheated by the carbon anode blocks, it will be transmitted through the circulating pipeline and used outside. Finally, after the gas in the storage tank 4 is stored for a certain period of time, it will be transmitted to the outside through the connecting pipeline 6 through the booster 5 for use.
