Description

Technical Field

[0001] This utility model belongs to the field of waste gas purification devices, specifically relating to a waste gas purification device in the process of treating waste manganese iron lithium batteries. Background Technology

[0002] Lithium manganese iron phosphate batteries, a common type of lithium battery, accumulate a significant amount of energy during use and have a relatively long lifespan. However, as their lifespan ends, these batteries gradually become waste. If not disposed of properly and promptly, these waste batteries not only consume substantial resources but may also cause serious environmental pollution, especially during the dismantling process, which may release a range of harmful gases such as fluorides, hydrogen, and sulfur dioxide.

[0003] Existing waste gas treatment devices typically employ a method of transporting waste gas to a purification tank and thoroughly mixing it with a purification liquid to remove harmful substances from the waste gas. Harmful substances in the waste gas, such as acidic gases, volatile organic compounds, nitrogen oxides, and sulfides, are dissolved, transformed, or adsorbed, thereby effectively removing harmful components and enabling the waste gas to meet emission standards, thus avoiding direct emissions that could damage the environment.

[0004] During the waste gas transport process, bubbles are generated inside the purification liquid. Due to the floating effect of the bubbles, the waste gas fails to fully contact and react with the purification liquid. Especially in areas with dense bubbles, the waste gas is easily carried out of the liquid surface and discharged into the outside world, resulting in some unpurified waste gas being directly discharged into the atmosphere, thus failing to meet environmental emission standards. Utility Model Content

[0005] In order to overcome the problem that existing waste gas treatment devices fail to fully contact and react with the purification liquid due to the floating effect of bubbles during purification, resulting in some unpurified waste gas being directly emitted into the atmosphere and failing to meet environmental emission standards, a waste gas purification device for the treatment process of waste manganese iron lithium batteries is proposed.

[0006] The technical solution of this utility model is as follows: a waste gas purification device in the process of treating waste manganese iron lithium batteries, including a treatment box; it also includes a first connecting pipe and a stirring assembly; the first connecting pipe is fixedly connected to the upper end of the treatment box, an exhaust box is fixedly connected to the upper end of the first connecting pipe, a limit box is fixedly connected to the upper end of the exhaust box, a self-locking screw is rotatably provided at the top of the inner wall of the limit box, an adjusting plate is threadedly installed on the outer wall of the self-locking screw, a sealing ball is slidably provided on the outer wall of the self-locking screw, a spring is fixedly connected between the sealing ball and the adjusting plate, a knob is rotatably provided at the upper end of the limit box, the knob is fixedly connected to the self-locking screw, and a stirring assembly is provided inside the treatment box.

[0007] Preferably, the outer wall of the adjusting plate is in contact with the inner wall of the limiting box, and the diameter of the sealing ball is larger than the diameter of the first connecting tube.

[0008] Preferably, an air inlet pipe is provided at the left end of the treatment box. The front of the air inlet pipe is L-shaped. The end of the air inlet pipe located inside the treatment box extends downward and is close to the bottom of the treatment box. A water tank is provided at the right end of the treatment box.

[0009] Preferably, a second connecting pipe is fixedly connected between the water tank and the treatment tank. The end of the second connecting pipe near the treatment tank extends to the left into the treatment tank and is fixedly connected to a filter cover.

[0010] Preferably, a water pump is fixedly connected to the upper end of the water tank, and an inlet pipe is fixedly connected to the outlet end of the water pump. The end of the inlet pipe away from the water pump passes through the treatment tank and is rotatably connected to a connecting sleeve. A through pipe is fixedly connected to the lower end of the connecting sleeve, and multiple nozzles are fixedly connected to the lower end of the through pipe.

[0011] Preferably, the stirring assembly includes a first motor, the first motor is fixedly connected to the upper end of the processing tank, a gear is fixedly connected to the output end of the first motor, and a gear ring is fixedly connected to the outer wall of the connecting sleeve, with the gear ring meshing with the gear.

[0012] Preferably, a fixing rod is fixedly connected to the center of the lower end of the pipe, and multiple stirring rods are fixedly connected to the outer wall of the fixing rod, with the multiple stirring rods arranged in a longitudinally staggered pattern.

[0013] The beneficial effects of this utility model are as follows: By rotating the knob, the self-locking screw is rotated, causing the adjusting plate to move downwards, changing the pressure of the spring on the sealing ball, and causing the gas inside the treatment box to accumulate. This ensures that the waste gas has enough time to be purified inside the treatment box. When the gas pressure rises above the downward pressure of the sealing ball, it will push the sealing ball up, allowing the gas accumulated inside the treatment box to be discharged to the outside. This solves the problem that due to the floating effect of the bubbles, the waste gas cannot fully contact and react with the purification liquid, resulting in some unpurified waste gas being directly discharged into the atmosphere, thus failing to meet environmental emission standards.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1-5 This utility model provides an embodiment of a waste gas purification device in the process of treating waste manganese iron lithium batteries, including a treatment box 1; it also includes a first connecting pipe 101 and a stirring assembly; the first connecting pipe 101 is fixedly connected to the upper end of the treatment box 1, and an exhaust box 102 is fixedly connected to the upper end of the first connecting pipe 101. A limit box 103 is fixedly connected to the upper end of the exhaust box 102. A self-locking screw 104 is rotatably provided at the top of the inner wall of the limit box 103. An adjusting plate 105 is threadedly installed on the outer wall of the self-locking screw 104. A sealing ball 106 is slidably provided on the outer wall of the self-locking screw 104. A spring 107 is fixedly connected between the sealing ball 106 and the adjusting plate 105. A knob 108 is rotatably provided at the upper end of the limit box 103. 108 is fixedly connected to the self-locking screw 104. The treatment box 1 is equipped with a stirring assembly. By rotating the knob 108, the self-locking screw 104 is rotated, causing the adjusting plate 105 to move downward, changing the pressure of the spring 107 on the sealing ball 106, so that the gas inside the treatment box 1 is gathered, ensuring that the waste gas has enough time to be purified in the treatment box 1. When the gas pressure rises above the downward pressure of the sealing ball 106, it will push the sealing ball 106 up, so that the gas gathered inside the treatment box 1 is discharged to the outside. This solves the problem that due to the floating effect of the bubbles, the waste gas cannot fully contact and react with the purification liquid, resulting in some unpurified waste gas being directly discharged into the atmosphere, thus failing to meet the environmental emission standards.

[0018] Please see Figures 2-5In this embodiment, the outer wall of the adjusting plate 105 is in contact with the inner wall of the limiting box 103. The diameter of the sealing ball 106 is larger than the diameter of the first connecting pipe 101. An air inlet pipe 2 is provided at the left end of the treatment box 1. The front of the air inlet pipe 2 is L-shaped. One end of the air inlet pipe 2 inside the treatment box 1 extends downward and is close to the bottom of the treatment box 1. A water tank 3 is provided at the right end of the treatment box 1. A second connecting pipe 4 is fixed between the water tank 3 and the treatment box 1. The end of the second connecting pipe 4 near the treatment box 1 extends to the left into the treatment box 1 and is fixed with a filter cover 5. A water pump 6 is fixed at the upper end of the water tank 3. A water inlet pipe 7 is fixed at the outlet end of the water pump 6. The end of the water inlet pipe 7 away from the water pump 6 passes through the treatment box 1 and is rotatably provided with a connecting sleeve 8. A through pipe 9 is fixed at the lower end of the connecting sleeve 8. Multiple nozzles 10 are fixed at the lower end of the through pipe 9. The waste gas generated during the treatment process is transported to the treatment box 1 through the air inlet pipe 2. The intake pipe 2 extends the exhaust gas to the bottom of the treatment tank 1, where it initially contacts the purification liquid inside. Then, the water pump 6 is activated to transport the purification liquid in the water tank 3 through the water inlet pipe 7 to the connecting pipe 9. Finally, multiple nozzles 10 spray out liquid mist to purify the dispersed exhaust gas, improving the purification effect. The sprayed liquid falls into the treatment tank 1, causing the liquid level inside the treatment tank 1 to rise. It then flows back into the water tank 3 through the second connecting pipe 4, achieving recycling. By setting a filter cover 5, impurities can be prevented from flowing into the water tank 3, avoiding clogging of the nozzles 10.

[0019] Please see Figure 4 and Figure 5 In this embodiment, the stirring assembly includes a first motor 201. The first motor 201 is fixedly connected to the upper end of the treatment tank 1. A gear 202 is fixedly connected to the output end of the first motor 201. A gear ring 203 is fixedly connected to the outer wall of the connecting sleeve 8. The gear ring 203 meshes with the gear 202. A fixing rod 204 is fixedly connected to the center of the lower end of the through pipe 9. Multiple stirring rods 205 are fixedly connected to the outer wall of the fixing rod 204. The multiple stirring rods 205 are arranged in a longitudinally staggered manner. By starting the first motor 201, the gear 202 is driven to rotate. The gear 202 meshes with the gear ring 203 on the connecting sleeve 8, driving the connecting sleeve 8, the through pipe 9 and the nozzle 10 to rotate. This allows for all-round spraying of the exhaust gas. At the same time, the fixing rod 204 at the lower end of the through pipe 9 drives the longitudinally staggered stirring rods 205 to rotate, fully stirring the exhaust gas and liquid mist in the treatment tank 1, so that the exhaust gas and the purification liquid are fully mixed and reacted, improving the purification effect.

[0020] In use, the exhaust gas generated during the treatment process is first transported to the treatment tank 1 through the air inlet pipe 2. The L-shaped air inlet pipe 2 extends the exhaust gas to the bottom of the treatment tank 1, where it initially contacts the purification liquid inside the treatment tank 1. Then, the water pump 6 is started to transport the purification liquid in the water tank 3 to the connecting pipe 9 through the water inlet pipe 7. Finally, multiple nozzles 10 spray out liquid mist to purify the dispersed exhaust gas, thereby improving the purification effect. The sprayed liquid will fall into the treatment tank 1, causing the liquid level inside the treatment tank 1 to rise. It will then flow back to the water tank 3 through the second connecting pipe 4, achieving recycling. By setting up a filter cover 5, impurities can be prevented from flowing into the water tank 3, avoiding the problem of clogging the nozzles 10. Then, by starting the first motor 201, the gear 202 is driven to rotate. The gear 202 meshes with the toothed ring 203 on the connecting sleeve 8, driving the connecting sleeve 8, the through pipe 9 and the nozzle 10 to rotate, so that the exhaust gas can be sprayed in all directions. At the same time, the fixed rod 204 at the lower end of the through pipe 9 drives the longitudinally staggered stirring rods 205 to rotate, which fully stirs the exhaust gas and liquid mist in the treatment box 1, so that the exhaust gas and the purification liquid are fully mixed and reacted, improving the purification effect.

[0021] During the purification process, rotating the knob 108 drives the self-locking screw 104 to rotate, causing the adjusting plate 105 to move downwards, changing the pressure of the spring 107 on the sealing ball 106, causing the gas inside the treatment box 1 to accumulate, ensuring that the exhaust gas has enough time to be purified inside the treatment box 1. When the gas pressure rises above the downward pressure of the sealing ball 106, it will push the sealing ball 106 up, causing the gas accumulated inside the treatment box 1 to be discharged to the outside, thus achieving efficient purification of the exhaust gas. Through the above steps, rotating the knob 108 drives the self-locking screw 104 to rotate, causing the adjusting plate 105 to move downwards, changing the pressure of the spring 107 on the sealing ball 106, causing the gas inside the treatment box 1 to accumulate, ensuring that the waste gas has enough time to be purified inside the treatment box 1. When the gas pressure rises above the downward pressure of the sealing ball 106, it will push the sealing ball 106 up, causing the gas accumulated inside the treatment box 1 to be discharged to the outside. This solves the problem that due to the floating effect of the bubbles, the waste gas cannot fully contact and react with the purification liquid, resulting in some unpurified waste gas being directly discharged into the atmosphere, thus failing to meet environmental emission standards.
