Description

Technical Field

[0001] This utility model relates to the field of battery recycling technology, specifically to a high-efficiency alloy lead smelting furnace for waste battery recycling. Background Technology

[0002] A smelting furnace is a device that melts metal ingots and some scrap metals, adds necessary alloying components, and then melts them into the desired alloy through operations such as slag removal and refining. Waste battery recycling refers to the reuse of used batteries, mainly by synthesizing recycled lead from the metals of waste batteries. The process of generating recycled lead involves smelting the metal scraps from lead-acid batteries in a metal smelting furnace and then synthesizing recycled lead. During the smelting of recycled lead, waste gas is generated. This waste gas cannot be directly discharged into the atmosphere and needs to be filtered. Traditional smelting furnaces often use fixed filter screens, which require the equipment to be shut down for replacement. To better filter the waste gas, a high-efficiency alloy lead smelting furnace for waste battery recycling is proposed.

[0003] For example, the lead recycling smelting furnace for waste lead-acid batteries disclosed in the authorization announcement number CN222617624U includes a smelting furnace, a flue pipe fixedly installed on the top of the smelting furnace, a feeding device fixedly installed on the upper part of the side wall of the smelting furnace, a heat exchange component fixedly installed outside the feeding device, and the end of the flue pipe away from the smelting furnace is fixedly connected to the heat exchange component.

[0004] Although the set heat exchange feeding device and heat exchange components work together to preheat the molten material in the feeding cylinder, during the heat exchange process, the rotating spiral plate of the heat exchange component will scrape off the dust accumulated on the inner wall of the heat exchange cylinder, and then transport it to the collection pipe, and finally collect it in the collection box, so as to avoid the dust accumulating inside the heat exchange cylinder for a long time, thereby affecting the heat exchange function of the heat exchange cylinder and thus failing to achieve the purpose of preheating the molten material;

[0005] However, the existing smelting furnaces do not solve the problems of being unable to filter exhaust gas through multiple channels and discharge recycled lead water at an angle during use, making it difficult to replace filter blocks without shutting down the furnace and flexibly adjust the discharge speed of recycled lead water, thus affecting the convenience of filter block replacement and recycled lead water discharge. Utility Model Content

[0006] The purpose of this utility model is to provide a high-efficiency alloy lead smelting furnace for waste battery recycling, so as to solve the problems mentioned in the background art, which are not conducive to multi-channel filtration and exhaust of waste gas and tilted discharge of recycled lead water, which are not conducive to non-stop replacement of filter blocks and flexible adjustment of the discharge speed of recycled lead water, thus affecting the convenience of filter block replacement and recycled lead water discharge.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency alloy lead smelting furnace for waste battery recycling, comprising a support frame and a smelting furnace body. The smelting furnace body is disposed above the support frame. A feeding port is disposed at the top of the smelting furnace body. A valve body is disposed at the top of the smelting furnace body on one side of the feeding port. Two sets of exhaust pipes are disposed at the top of the valve body. A filter block is disposed at the port position of the top of each exhaust pipe. Four sets of equally spaced limiting blocks are disposed on the side wall of each filter block. An equal-spaced limit block is disposed on the inner wall of each exhaust pipe. The valve body has four sets of limiting grooves with varying spacing, and the limiting blocks slide in conjunction with the limiting grooves. An electric push rod is movably mounted on the outer wall of the valve body. A push arm is mounted on the output end of the electric push rod. A linkage arm is provided at the end of the push arm away from the electric push rod. A hinge shaft is provided at the end of the linkage arm near the push arm, and the linkage arm is movably connected to the push arm through the hinge shaft. An adjustment shaft is fixedly mounted at the end of the linkage arm away from the push arm, and the adjustment shaft extends into the interior of the valve body and is movably connected to the valve body. A valve plate is slidably mounted inside the valve body, and the adjustment shaft is connected to the valve plate.

[0008] Preferably, a discharge port is provided on the outer wall of the smelting furnace body, and multiple sets of heating wires are provided in the interlayer position of the smelting furnace body.

[0009] Preferably, air inlets are symmetrically arranged on the side wall of the smelting furnace body, and flexible hoses are provided at the port positions of the air inlets.

[0010] Preferably, a movable shaft is provided on the side wall of the smelting furnace body on the side of the air inlet, and the movable shaft is movably connected to the support frame.

[0011] Preferably, a drive seat is provided on the side wall of the support frame, and the movable shaft extends into the interior of the drive seat and is movably connected to the drive seat.

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

[0013] Preferably, a worm wheel is provided on the movable shaft surface 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: the smelting furnace not only realizes multi-channel filtration and exhaust of waste gas and inclined discharge of recycled lead molten metal, facilitating the replacement of filter blocks without stopping the machine and flexibly adjusting the discharge speed of recycled lead molten metal, but also improves the convenience of filter block replacement and recycled lead molten metal discharge.

[0015] (1) The metal scrap from the waste batteries is poured into the interior of the smelting furnace through the feeding port. The interior of the smelting furnace is heated by the heating wire to melt the metal scrap into recycled lead. The flexible hose is connected to the external fan, and the fan delivers external air into the smelting furnace through the flexible hose and the air inlet to provide an oxygen-rich environment for the metal scrap to melt. The metal scrap will produce harmful gases after melting. The gases enter the interior of a set of exhaust pipes through the valve body and are discharged into the atmosphere after being filtered by the corresponding filter blocks. When it is necessary to replace the filter blocks currently in use, the push arm is moved by the electric push rod. The push arm drives the linkage arm to rotate via the hinge shaft, and the linkage arm drives the valve plate to rotate via the adjustment shaft. The valve plate blocks the currently used exhaust pipe channel, allowing the exhaust gas to be discharged from another set of exhaust pipes. Then, the filter block inside the exhaust pipe that needs to be replaced is rotated, and the filter block drives the limit block to rotate. When the limit block rotates to the turning position of the limit groove, the filter block can be pulled out from inside the exhaust pipe. Then, a new filter block can be installed back into the exhaust pipe. This allows for convenient filter block replacement without stopping the machine, realizing multi-channel filtration and exhaust gas discharge, facilitating filter block replacement without stopping the machine, and improving the convenience of filter block replacement.

[0016] (2) The worm is driven to rotate by the stepper motor, and the worm drives a set of movable shafts to rotate through the worm wheel. The movable shafts drive the smelting furnace body to rotate and tilt, so that the recycled lead water is discharged from the outlet. The discharge speed of the recycled lead water is different depending on the tilt angle of the smelting furnace body. It can be flexibly adapted to different discharge scenarios, which facilitates the tilt discharge of recycled lead water, facilitates the flexible adjustment of the discharge speed of recycled lead water, and improves the convenience of recycled lead water discharge.

The smelting furnace body 2 is disposed above the support frame 1. A feeding port 6 is disposed at the top of the smelting furnace body 2. A valve body 7 is disposed at the top of the smelting furnace body 2 on one side of the feeding port 6. Two sets of exhaust pipes 19 are disposed at the top of the valve body 7. A filter block 20 is disposed at the port position of the top of each exhaust pipe 19. Four sets of equally spaced limiting blocks 21 are disposed on the side wall of each filter block 20. Four sets of equally spaced limiting grooves 22 are disposed on the inner wall of each exhaust pipe 19, and the limiting blocks 21 slide with the limiting grooves 22. In conjunction with this, an electric push rod 14 is movably mounted on the outer wall of the valve body 7. The electric push rod 14 serves as a power drive.

A hinge shaft 16 is provided at the end of the linkage arm 17 near the push arm 15. The linkage arm 17 is movably connected to the push arm 15 through the hinge shaft 16. An adjustment shaft 18 is fixedly mounted at the end of the linkage arm 17 away from the push arm 15. The adjustment shaft 18 extends into the interior of the valve body 7 and is movably connected to the valve body 7. A valve plate 23 is slidably arranged inside the valve body 7. The adjustment shaft 18 is connected to the valve plate 23.

[0028] Metal scrap from used batteries is poured into the furnace body 2 through the feeding port 6. The heating wire 9 is then turned on to heat the interior of the furnace body 2, melting the metal scrap into recycled lead. A flexible hose 5 is connected to an external fan, which draws outside air through the hose and inlet 4 into the furnace body 2, providing an oxygen-rich environment for the melting of the metal scrap. The melting of the metal scrap produces harmful gases, which pass through valve 7 into a set of exhaust pipes 19 and are filtered by corresponding filter blocks 20 before being discharged into the atmosphere. When the filter block 20 needs to be replaced, the electric push rod 14 is activated, moving the push arm 15. 5. The linkage arm 17 is rotated by the hinge shaft 16, and the linkage arm 17 rotates the valve plate 23 by the adjustment shaft 18. The valve plate 23 blocks the channel of the currently used exhaust pipe 19, so that the exhaust gas is discharged from another set of exhaust pipes 19. Then, the filter block 20 inside the exhaust pipe 19 that needs to be replaced is rotated. The filter block 20 drives the limit block 21 to rotate. When the limit block 21 rotates to the turning position of the limit groove 22, the filter block 20 is pulled out and removed from the exhaust pipe 19. Then, a new filter block 20 is installed back into the exhaust pipe 19. This makes it convenient to replace the filter block 20 without stopping the machine, realizes multi-channel filtration and exhaust gas discharge, facilitates the replacement of filter blocks without stopping the machine, and improves the convenience of filter block replacement.

[0029] The outer wall of the smelting furnace body 2 is provided with a discharge port 3, and multiple sets of electric heating wires 9 are provided at the interlayer position of the smelting furnace body 2. The side wall of the smelting furnace body 2 is symmetrically provided with air inlets 4, and each air inlet 4 is provided with a flexible hose 5 at its port position.

[0030] A movable shaft 13 is provided on the side wall of the smelting furnace body 2 on one side of the air inlet 4, and the movable shaft 13 is movably connected to the support frame 1.

[0032] A worm wheel 11 is provided on the surface of the movable shaft 13 on one side of the worm 10, and the worm 10 and the worm wheel 11 mesh with each other;

[0033] When it is necessary to discharge recycled lead, the stepper motor 12 is turned on, which drives the worm gear 10 to rotate. Under the mutual meshing of the worm gear 10 and the worm wheel 11, the worm gear 10 drives a set of movable shafts 13 to rotate through the worm wheel 11. With the movable shafts 13 and the support frame 1 in motion, the movable shafts 13 drive the smelting furnace body 2 to rotate and tilt, so that the recycled lead is discharged from the discharge port 3. The discharge speed of the recycled lead varies with different tilt angles of the smelting furnace body 2, which can flexibly adapt to different discharge scenarios, facilitate tilting discharge of recycled lead, facilitate flexible adjustment of the discharge speed of recycled lead, and improve the convenience of recycled lead discharge.

[0034] Work steps

[0035] Metal scrap from used batteries is poured into the furnace body 2 through the feeding port 6. Heating wire 9 heats the interior of the furnace body 2, melting the metal scrap into recycled lead. A flexible hose 5 is connected to an external fan, which draws outside air through the hose and inlet 4 into the furnace body 2, providing an oxygen-rich environment for the melting of the metal scrap. The melting of the metal scrap produces harmful gases, which pass through valve body 7 into a set of exhaust pipes 19 and are filtered by corresponding filter blocks 20 before being discharged into the atmosphere. When the filter block 20 needs to be replaced, an electric push rod 14 moves the push arm 15, which in turn rotates the linkage arm 17 via hinge shaft 16. The linkage arm 17 then rotates the valve plate 23 via adjusting shaft 18, sealing the currently used exhaust pipe 19. The exhaust gas is discharged from another set of exhaust pipes 19. Then, the filter block 20 inside the exhaust pipe 19 that needs to be replaced is rotated. The filter block 20 drives the limiting block 21 to rotate. When the limiting block 21 rotates to the turning position of the limiting groove 22, the filter block 20 is pulled out and removed from the exhaust pipe 19. Then, a new filter block 20 is installed back into the exhaust pipe 19 to facilitate the replacement of the filter block 20 without stopping the machine. When it is necessary to discharge the recycled lead, the stepper motor 12 drives the worm gear 10 to rotate. The worm gear 10 drives a set of movable shafts 13 to rotate through the worm wheel 11. The movable shafts 13 drive the smelting furnace body 2 to rotate and tilt, so that the recycled lead is discharged from the discharge port 3. The discharge speed of the recycled lead varies depending on the tilt angle of the smelting furnace body 2, which can flexibly adapt to different discharge scenarios. The above is the complete usage of the high-efficiency alloy lead smelting furnace for waste battery recycling.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
