Description

Technical Field

[0001] This utility model relates to the technical field of waste gas purification devices, specifically a waste gas purification device for alloy lead smelting in waste battery recycling. Background Technology

[0002] Waste battery recycling refers to the reuse of used batteries. Lead-acid batteries are the most commonly used industrial batteries in China, with lead accounting for more than half of the total cost. Lead is mainly recovered through pyrometallurgical processes, hydrometallurgical processes, and solid-phase electrolytic reduction technology. When recycling lead from batteries, a smelting furnace is needed to heat and smelt the batteries. However, the smelting process generates waste gas, which pollutes the environment and cannot be directly discharged into the air. The waste gas needs to be purified before it can be discharged. Traditional waste gas purification methods mostly involve placing filter blocks to filter harmful gases in the waste gas, but the filtration efficiency is poor. To improve this situation, a waste gas purification device for alloy lead smelting in waste battery recycling is proposed.

[0003] As disclosed in the authorization announcement number CN218281017U, a smelting furnace exhaust gas purification device includes a purification box. An air inlet pipe is connected to one side of the top of the purification box, and an exhaust pipe is connected to the other side of the top of the purification box. A central plate is welded to the bottom of the inner side of the purification box, and side plates are welded to both sides of the central plate. One end of the side plate is welded to the top surface of the inner side of the purification box, and multiple filter plates are welded between the side plate and the inner wall of the purification box. An ash collection box is welded to the lower side of the purification box, and an ash discharge port is opened through the purification box of the ash collection box. A movable plate is sleeved in the ash discharge port by a round rod.

[0004] Although it achieves the function of pulling a rope led out of the ash collection box, causing the rope to pull the movable plate inside the ash discharge port to tilt, thus exposing the ash discharge port, the pulse controller activates the pulse solenoid valve, causing the pulse solenoid valve to intermittently inject air into the blow pipe, and then the multiple branches of the blow pipe blow the air from the nozzle from bottom to top onto the filter plate, so that the dust attached to the surface of the filter plate passes through the ash discharge port into the ash collection box, until the dust falls to the bottom of the ash collection box under its own weight for collection, maintaining the filtration effect of the filter plates on both sides inside the purification box; by pulling out the insert block in the second insert ear, the trapezoidal block of the insert block is disengaged from the second insert ear, thus unlocking the insert plate in the insertion port, and then pulling the insert plate to remove it from the purification box, which facilitates the replacement of the activated carbon adsorption plate;

[0005] However, it does not solve the problems that existing exhaust gas purification devices are not conducive to acid-base neutralization and filtration of harmful substances in exhaust gas, nor to stirring the neutralization liquid to increase the uniformity of contact between exhaust gas and neutralization liquid, nor to the quick disassembly and replacement of filter blocks, thus affecting the exhaust gas purification effect. Utility Model Content

[0006] The purpose of this utility model is to provide a waste gas purification device for alloy lead smelting in waste battery recycling, so as to solve the problems mentioned in the background art that the waste gas purification device is not convenient for acid-base neutralization treatment and filtration of harmful substances in the waste gas, is not conducive to stirring the neutralization liquid to increase the uniformity of contact between the waste gas and the neutralization liquid, and is not conducive to the quick disassembly and replacement of the filter block, thus affecting the waste gas purification effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waste gas purification device for alloy lead smelting in waste battery recycling, comprising a purification tank and an exhaust pipe. The top of the purification tank is provided with an exhaust pipe, and a drive seat is provided on the top of the purification tank on one side of the exhaust pipe. The top of the drive seat is provided with an adapter frame, and an adapter sleeve is provided at the center of the adapter frame. A liquid filling pipe is provided on the top of the purification tank on one side of the drive seat, and a liquid drain pipe is provided at the bottom of the purification tank. A solenoid valve is provided inside the liquid drain pipe. A hollow tube is movably arranged at the center of the drive seat and extends into the interior of the purification tank. The hollow tube is movably connected to the adapter sleeve. Multiple sets of stirring tubes with equal spacing are provided on the surface of the hollow tube, and the stirring tubes are connected to the hollow tube. Multiple sets of holes with equal spacing are provided on the surface of the stirring tubes.

[0008] Preferably, an upper scraper is symmetrically arranged on the side wall of the hollow tube, and the upper scraper is slidably connected to the purification tank.

[0009] Preferably, a lower scraper is symmetrically arranged on the side wall of the hollow tube below the upper scraper, and the lower scraper is slidably connected to the purification tank.

[0010] Preferably, the inner wall of the exhaust pipe is provided with four sets of equally spaced limiting grooves, and a filter block is provided inside the exhaust pipe.

[0011] Preferably, the filter block has four sets of equally spaced limiting blocks on its side wall, and the limiting blocks are slidably connected to the limiting grooves, and the top of the filter block has a handle.

[0012] Preferably, a stepper motor is provided on the side wall of the drive base, and a worm gear is provided at the output end of the stepper motor, and the worm gear is movably connected to the drive base.

[0013] Preferably, a worm wheel is fitted onto the surface of the hollow tube on one side of the worm, and the worm and the worm wheel mesh with each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this waste gas purification device not only achieves acid-base neutralization treatment and filtration purification of harmful substances in waste gas, but also facilitates stirring of the neutralization liquid to increase the uniformity of contact between waste gas and neutralization liquid, and facilitates quick disassembly and replacement of filter blocks, but also improves the waste gas purification effect.

[0015] (1) The acid-base neutralization liquid is injected into the purification tank through the liquid addition pipe. The liquid level of the neutralization liquid exceeds the stirring pipe. Then, the gas supply pipe of the smelting furnace is connected to the adapter sleeve. The waste gas is transported to the inside of the stirring pipe through the gas supply pipe, adapter sleeve, and hollow pipe, and is transported to the acid-base neutralization liquid through the holes on the surface of the stirring pipe. The neutralization liquid neutralizes the acid and base substances in the waste gas. The treated waste gas is filtered by the filter block and discharged from the exhaust pipe. When the filter block needs to be replaced after a long period of use, turn the handle. The handle drives the filter block to rotate inside the exhaust pipe. When the limit block rotates to the turning position of the limit groove, pull the handle upward. The handle can drive the filter block to be pulled out from inside the exhaust pipe. Then, replace the new filter block and reinstall it inside the exhaust pipe. This realizes the acid-base neutralization treatment and the filtration and purification of harmful substances in the waste gas, and facilitates the quick disassembly and replacement of the filter block.

[0016] (2) The stepper motor drives the worm gear to rotate, and the worm gear drives the hollow tube to rotate through the worm wheel. The adapter and adapter sleeve provide movable support for the hollow tube. The hollow tube drives the stirring tube to rotate, and the stirring tube stirs the neutralizing liquid, so that the gas and the neutralizing liquid are in more uniform contact, thereby improving the acid-base neutralization effect. At the same time, the exhaust gas will be mixed with dust. During the exhaust gas purification process, the dust will adhere to the inner wall of the purification tank. While the hollow tube rotates, the hollow tube drives the upper and lower scraper to rotate. The upper and lower scraper scrapers clean the inner wall of the purification tank to prevent dust from adhering to the inner wall of the purification tank. After the exhaust gas is treated, the solenoid valve inside the drain pipe is opened to discharge the waste liquid, which facilitates the stirring of the neutralizing liquid, increases the uniformity of contact between the exhaust gas and the neutralizing liquid, and prevents dust and impurities from adhering to the inner wall of the purification tank, thus improving the exhaust gas purification effect.

[0026] Example 1

[0027] Please see Figure 1-5An embodiment of this utility model provides a waste lead alloy smelting waste gas purification device in waste battery recycling, including a purification tank 1 and an exhaust pipe 2. The top of the purification tank 1 is provided with an exhaust pipe 2. The top of the purification tank 1 on one side of the exhaust pipe 2 is provided with a drive seat 3. The top of the drive seat 3 is provided with a transfer frame 4. The center of the transfer frame 4 is provided with a transfer sleeve 5. The top of the purification tank 1 on one side of the drive seat 3 is provided with a liquid filling pipe 6. The bottom of the purification tank 1 is provided with a liquid drain pipe 7. The inside of the liquid drain pipe 7 is provided with a solenoid valve 12. The center of the drive seat 3 is movably provided with a hollow tube 8, which extends into the interior of the purification tank 1 and is movably connected to the transfer sleeve 5. The surface of the hollow tube 8 is provided with multiple sets of stirring tubes 9 at equal intervals, and the stirring tubes 9 are connected to the hollow tube 8. The surface of the stirring tubes 9 is provided with multiple sets of holes at equal intervals.

[0028] When waste batteries are melted down, a mixed gas containing acidic and alkaline substances is generated. Acid-base neutralization solution is injected into purification tank 1 through filling pipe 6, with the liquid level exceeding that of stirring pipe 9. Then, the gas supply pipe of the melting furnace is connected to adapter sleeve 5. Waste gas is transported through the gas supply pipe, adapter sleeve 5, and hollow pipe 8 to the interior of stirring pipe 9, and then through holes on the surface of stirring pipe 9 into the acid-base neutralization solution. The neutralization solution neutralizes the acidic and alkaline substances in the waste gas. The treated waste gas is then filtered through filter block 15 and discharged from exhaust pipe 2. Filter block 15 is long... When the filter needs to be replaced after a period of use, turn the handle 16. With the sliding cooperation between the limit block 14 and the limit groove 13, the handle 16 will drive the filter block 15 to rotate inside the exhaust pipe 2. When the limit block 14 rotates to the turning position of the limit groove 13, pull the handle 16 upward. The handle 16 will then drive the filter block 15 out of the exhaust pipe 2. After that, replace the filter block 15 and reinstall it inside the exhaust pipe 2. This achieves acid and alkali neutralization treatment and filtration and purification of harmful substances in the exhaust gas, making it convenient to quickly disassemble and replace the filter block.

[0029] The hollow tube 8 is symmetrically provided with an upper scraper 10 on its side wall, and the upper scraper 10 is slidably connected to the purification tank 1.

[0030] A lower scraper 11 is symmetrically arranged on the side wall of the hollow tube 8 below the upper scraper 10, and the lower scraper 11 is slidably connected to the purification tank 1. Four sets of limiting grooves 13 with equal spacing are arranged on the inner wall of the exhaust pipe 2, and a filter block 15 is arranged inside the exhaust pipe 2.

[0031] The filter block 15 has four sets of equally spaced limiting blocks 14 on its side wall, and the limiting blocks 14 are slidably connected to the limiting groove 13. The top of the filter block 15 is provided with a handle 16.

[0032] A stepper motor 17 is provided on the side wall of the drive base 3. The stepper motor 17 plays the role of power drive. A worm gear 18 is provided at the output end of the stepper motor 17, and the worm gear 18 is movably connected to the drive base 3.

[0033] A worm wheel 19 is fitted on the surface of the hollow tube 8 on one side of the worm 18, and the worm 18 and the worm wheel 19 mesh with each other;

[0034] Simultaneously, stepper motor 17 is turned on, driving worm gear 18 to rotate. Through the meshing of worm gear 18 and worm wheel 19, worm gear 18 drives hollow tube 8 to rotate. Adapter frame 4 and adapter sleeve 5 provide movable support for hollow tube 8. Hollow tube 8 drives stirring tube 9 to rotate, stirring the neutralizing liquid and thus making the contact between gas and neutralizing liquid more uniform, thereby improving the acid-base neutralization effect. Meanwhile, the exhaust gas contains dust, which will adhere to the dust during the exhaust gas purification process. On the inner wall of the purification tank 1, as the hollow tube 8 rotates, the upper scraper 10 and the lower scraper 11 rotate, and the upper scraper 10 and the lower scraper 11 scrape and clean the inner wall of the purification tank 1 to prevent dust from adhering to the inner wall of the purification tank 1. After the waste gas is treated, the solenoid valve 12 inside the drain pipe 7 is opened to discharge the waste liquid, which facilitates the stirring of the neutralizing liquid, increases the uniformity of contact between the waste gas and the neutralizing liquid, prevents dust and impurities from adhering to the inner wall of the purification tank, and improves the waste gas purification effect.

[0035] Work steps

[0036] When waste batteries are smelted, a mixed gas containing acidic and alkaline substances is generated. First, an acid-base neutralization solution is injected into the purification tank 1 through the liquid addition pipe 6, with the liquid level exceeding that of the stirring pipe 9. Then, the gas supply pipe of the smelting furnace is connected to the adapter sleeve 5. The waste gas is transported through the gas supply pipe, adapter sleeve 5, and hollow pipe 8 to the interior of the stirring pipe 9, and then through the holes on the surface of the stirring pipe 9 into the acid-base neutralization solution. The neutralization solution neutralizes the acidic and alkaline substances in the waste gas. After being treated, the waste gas is filtered by the filter block 15 and discharged from the exhaust pipe 2. When the filter block 15 needs to be replaced after a long period of use, the handle 16 drives the filter block 15 to rotate inside the exhaust pipe 2. When the limiting block 14 rotates to the turning position of the limiting groove 13, the handle 16 is pulled upwards, which allows the handle 16 to pull the filter block 15 out of the exhaust pipe 2. Then, a new filter block 15 is installed inside the exhaust pipe 2. The stepper motor 17 drives the worm gear 18 to rotate, and the worm gear 18 drives the hollow tube 8 to rotate through the worm wheel 19. The adapter frame 4 and adapter sleeve 5 provide movable support for the hollow tube 8. The hollow tube 8 drives the stirring tube 9 to rotate, and the stirring tube 9 stirs the neutralizing liquid, so that the gas and the neutralizing liquid are in more uniform contact, thereby improving the acid-base neutralization effect. At the same time, the exhaust gas will contain dust. During the purification process, the dust will adhere to the inner wall of the purification tank 1. While the hollow tube 8 is rotating, the hollow tube 8 drives the upper scraper frame 10 and the lower scraper frame 11 to rotate. The upper scraper frame 10 and the lower scraper frame 11 scrape and clean the inner wall of the purification tank 1 to prevent dust from adhering to the inner wall of the purification tank 1. After the exhaust gas is treated, the solenoid valve 12 inside the drain pipe 7 is opened to discharge the waste liquid. The above is the complete usage of the exhaust gas purification device for alloy lead smelting in waste battery recycling.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
