Description

Technical Field

[0001] This utility model relates to the field of lithium manganese oxide technology, specifically to a waste gas treatment device for lithium manganese oxide sintering. Background Technology

[0002] Lithium manganese oxide, primarily spinel-type lithium manganese oxide (LiMn₂O₄), was first synthesized by Hunter in 1981 as a cathode material with three-dimensional lithium-ion channels. It has since attracted significant attention from scholars and researchers both domestically and internationally due to its advantages as an electrode material, including low cost, high potential, environmental friendliness, and high safety performance. However, the sintering process of lithium manganese oxide generates a large amount of waste gas, necessitating its treatment.

[0003] A sintering furnace exhaust gas treatment device, with announcement number CN 220728956U, can achieve more uniform and rapid treatment of exhaust gas by utilizing the distribution pipe and distribution holes set at the bottom of the plug, thereby achieving a more practical purpose.

[0004] There are still some shortcomings in its use. When treating waste gas, the temperature of the waste gas is high. Directly discharging the waste gas will cause heat loss, thereby reducing the quality of waste gas treatment and wasting resources. At the same time, since the waste gas contains impurities, it cannot be filtered, which will also reduce the subsequent treatment effect of the waste gas. Therefore, we propose a waste gas treatment device for lithium manganese oxide sintering. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0025] A waste gas treatment device for lithium manganese oxide sintering includes a base plate 1, a sintering box 3 slidably connected to the top of the base plate 1, a first cover plate 4 abutting the top of the sintering box 3, a suction pump 8 installed on the top of the base plate 1, a suction pipe 7 fixedly connected to one end of the suction pump 8, a groove 19 opened in the suction pipe 7, a first magnetic plate 20 fixedly connected in the groove 19, a second magnetic plate 21 magnetically connected to the side of the first magnetic plate 20, a second screen 22 fixedly connected to the side of the second magnetic plate 21, a connecting ring 6 provided on the outside of the suction pipe 7, a first screen 17 fixedly connected to the side end of the connecting ring 6, and a sealing ring 18 fixedly connected to the inner wall of the connecting ring 6, the sealing ring 18 abutting against the outer surface of the suction pipe 7.

[0026] In this embodiment, as Figure 1 and Figure 2As shown, a treatment box 9 is fixedly connected to the top of the base plate 1. The other end of the air pump 8 extends into the treatment box 9 and communicates with it. A suction plate 27 is adsorbed and connected to the inner wall of the treatment box 9. Activated carbon balls 26 are fixedly connected to the side of the suction plate 27. A temperature sensor 25 is fixedly connected to the inner wall of the treatment box 9. An air outlet pipe 15 is fixedly connected to the side of the treatment box 9. A valve 16 is installed on the outside of the air outlet pipe 15. The air outlet pipe 15 communicates with the treatment box 9. A steel plate 24 is fixedly connected to the inner wall of the treatment box 9. A water tank 23 is abutted against the top of the steel plate 24.

[0027] The exhaust gas can be drawn into the treatment box 9 by the suction of the air pump 8. Then, the impurities in the exhaust gas can be filtered by the first screen 17 and the second screen 22 to improve the quality of exhaust gas treatment. At the same time, the first screen 17 and the second screen 22 can be separated from the air extraction pipe 7, which makes it easy to clean the first screen 17 and the second screen 22.

[0028] In this embodiment, as Figure 3 and Figure 4 As shown, the top of the processing box 9 abuts against the second cover plate 10, and the second cover plate 10 has a top groove 11. The surface of the bottom plate 1 is fixedly connected to the control plate 5, which is electrically connected to the temperature sensor 25 and the valve 16. The bottom of the bottom plate 1 is fixedly connected to the support base 2, which has anti-slip texture and is T-shaped. The processing box 9 has a through groove 12, and the through groove 12 abuts against the side cover 13. The outer surface of the side cover 13 is fixedly connected to the pull ring 14.

[0029] The process involves allowing waste gas to enter the treatment chamber 9, where activated carbon balls 26 adsorb impurities. Simultaneously, the waste gas can heat the water inside the water tank 23. This heat exchange prevents the waste gas from being directly discharged, thus avoiding heat waste. When the temperature of the waste gas decreases, valve 16 opens, allowing the waste gas to be discharged, thereby completing the waste gas treatment process.

[0030] The working process of this utility model is as follows: When the waste gas treatment device for lithium manganese oxide sintering designed in this scheme is in operation, when waste gas is generated in the sintering box 3, it is drawn into the treatment box 9 by the suction of the air pump 8 through the first screen 17 and the second screen 22. The heat contained in the waste gas can heat the water in the water tank 23, preventing the hot gas from being directly discharged to the outside and causing heat loss. At the same time, the activated carbon balls 26 can adsorb and filter the debris contained in the waste gas. When the temperature sensor 25 detects that the temperature inside the treatment box 9 is relatively high... When the temperature is low, the valve 16 is opened under the action of the control panel 5, allowing the exhaust gas to be discharged through the exhaust pipe 15, thus completing the exhaust gas treatment. At the same time, when it is necessary to clean the first screen 17 and the second screen 22, the sintering box 3 can be moved to the outside of the connecting ring 6, and the connecting ring 6 can be separated from the exhaust pipe 7 by pulling the connecting ring 6. Then, the second screen 22 can be pulled to separate the first magnetic plate 20 and the second magnetic plate 21, thereby cleaning the first screen 17 and the second screen 22, making the exhaust gas treatment equipment more practical and convenient to use.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
