Description

Technical Field

[0001] This utility model relates to the field of lead recycling technology, specifically to a lead ingot smelting and heating device for lead-acid battery recycling. Background Technology

[0002] Lead-acid batteries are rechargeable batteries whose electrodes are primarily made of lead and its oxides, and whose electrolyte is a sulfuric acid solution. In the discharged state, the positive electrode is mainly composed of lead dioxide, and the negative electrode is mainly composed of lead. In the charged state, both the positive and negative electrodes are mainly composed of lead sulfate. Lead bars are a commonly used component, and their quality is crucial to the production of lead-acid batteries. Lead bars are generally formed by heating and melting lead ingots, then cooling and shaping them.

[0003] Patent document CN215810150U discloses an electrically heated lead ingot smelting pot. This pot, employing the aforementioned structure, heats and melts lead ingots via a heater and heating tubes. The molten lead flows into the casting head through a discharge channel within a plug. The flow rate of the molten lead is controlled by a plug rod, and the opening of the discharge channel is controlled by a control cylinder. A hood collects harmful gases. When the molten lead is discharged from the pot, it exits through a discharge hole on the plug. However, when impurities in the molten lead enter the discharge hole, the plug rod cannot penetrate it, making it difficult to effectively clear the blockage.

[0004] Patent document CN208532896U discloses a lead ingot smelting and heating device for lead-acid battery recycling. During operation, a gas supply pipe delivers fuel gas to the cylinder. The operator ignites the gas and continues to supply gas into the cylinder. By controlling the forward movement of the wheels, the feed cover is moved open, exposing the feed inlet. Recycled lead raw material is fed into the cylinder through the feed inlet. After a specified amount is delivered, the wheels are controlled to move in the reverse direction to close the feed inlet. The gas supply pipe continues to supply fuel gas into the cylinder, while simultaneously driving gears to rotate the cylinder until smelting is complete. The cylinder rotates until the discharge cover faces downwards, the gas supply pipe stops supplying fuel gas, and the cylinder stops rotating. At this point, the sliding discharge cover opens the discharge outlet, and the recycled lead is discharged from the cylinder under its own weight. This device directly heats the lead inside the cylinder through the gas supply pipe; therefore, the gas supply pipe can only rapidly heat the nearby recycled lead raw material, resulting in low efficiency in heating the recycled lead raw material. Utility Model Content

[0005] The technical problem to be solved by this utility model is a lead ingot smelting heating device for lead-acid battery recycling that can prevent lead liquid from clogging the outlet channel, facilitate the unblocking of the outlet channel, and has high heating efficiency for recycled lead raw materials.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A lead ingot smelting heating device for lead-acid battery recycling includes a furnace body. An arc-shaped tube is fixed to one side of the furnace body, with both ends of the arc-shaped tube connecting to the inside and outside of the furnace body respectively. Both ends of the arc-shaped tube are bent upwards. An arc-shaped rod is slidably sealed inside the arc-shaped tube, passing through the arc-shaped tube. One end of the arc-shaped rod inside the furnace body is fixedly connected to the lower end of a swing rod. The upper end of the swing rod is rotatably connected to an ear plate via a pin. The ear plate is fixed inside the furnace body. The pin, arc-shaped rod, and arc-shaped tube are concentric. A top cover is detachably fixedly connected to the upper end of the furnace body. An upper hole is opened on one side of the top cover. A winch is fixed to the upper end of the top cover. The wire rope of the winch passes through the upper hole and is fixedly connected to the swing rod. A storage tank is fixed to the outside of the furnace body. One end of the arc-shaped tube outside the furnace body is connected to the storage tank. An outlet pipe is fixedly connected to the storage tank. A valve is installed on the outlet pipe. A lower heating component and an upper heating component are respectively installed at the lower and upper ends of the furnace body.

[0008] Specifically, the lower heating assembly includes an electric heating tube fixed inside the lower end of the furnace body.

[0009] Specifically, the upper heating assembly includes a cover plate with an eccentrically connected connecting pipe. The connecting pipe movably passes through the cover plate and is perpendicular to it. A branch pipe perpendicular to the connecting pipe is fixedly connected to the lower end of the connecting pipe, and multiple burners are fixedly connected to the lower end of the branch pipe. The connecting pipe portion below the cover plate passes through the inlet hole on the upper cover, and the connecting pipe portion below the cover plate movably passes through a connecting plate. The connecting plate is fixed inside one side of the inlet hole. A vertical cylinder is fixed to the upper end of the cover plate, and an upper plate is fixed to the telescopic rod of the cylinder. The upper plate is rotatably connected to the upper end of the connecting pipe. A motor is fixed to the upper end of the upper plate, and the output shaft of the motor is concentrically fixedly connected to the upper end of the connecting pipe. A rotating sleeve is rotatably and sealingly connected to the connecting pipe portion between the upper plate and the cover plate. The rotating sleeve is connected to the connecting pipe and fixedly connected to the upper plate. A flexible hose is fixedly connected to the rotating sleeve.

[0010] Specifically, a solenoid valve is installed on the hose, and a gas concentration sensor is fixed at the lower end of the upper cover. The gas concentration sensor, controller, and solenoid valve are electrically connected.

[0011] Specifically, the furnace body includes an inner shell and an outer shell. A heat-conducting metal plate is fixed between the inner shell and the outer shell at the arc-shaped tube. The heat-conducting metal plate is in close contact with the outer wall of the inner shell and the inner wall of the outer shell. The arc-shaped tube passes through the heat-conducting metal plate, and the outer shell and the inner shell can conduct heat to the storage tank through the heat-conducting metal plate.

[0012] Specifically, refractory cement is used to fill the space between the inner shell and the outer shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device, by setting up upper and lower heating components, can rapidly heat the recycled lead raw materials entering the furnace.

[0015] 2. The upper heating component can move up and down and rotate at the same time. The flames emitted from the burner can evenly heat the recycled lead raw materials in the furnace, thereby improving the heating efficiency of the recycled lead raw materials in the furnace.

[0016] 3. The curved rod can pass through the curved tube, and the curved rod can clear the blockage of the curved tube.

[0017] 4. By setting up a storage tank and installing a valve on the outlet pipe of the storage tank, the outflow of lead liquid can be easily controlled by controlling the opening degree of the valve.

[0018] 5. A heat-conducting metal plate is installed between the outer shell and the inner shell at the arc-shaped tube, and the outer shell and the inner shell can conduct heat to the storage tank through the heat-conducting metal plate.

[0019] 5. Because one end of the arc-shaped rod inside the furnace is bent upwards, impurities that settle in the lower layer of the molten lead inside the furnace cannot flow out through the arc-shaped pipe, thus maintaining the purity of the molten lead flowing out of the arc-shaped pipe.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1: Refer to Figures 1-3As shown, the lead ingot smelting heating device for lead-acid battery recycling includes a furnace body. An arc-shaped tube 6 is fixed on one side of the furnace body. The two ends of the arc-shaped tube 6 are connected to the inside and outside of the furnace body respectively. Both ends of the arc-shaped tube 6 are bent upward. An arc-shaped rod 7 is slidably sealed inside the arc-shaped tube 6. The arc-shaped rod 7 passes through the arc-shaped tube 6. One end of the arc-shaped rod 7 inside the furnace body is fixedly connected to the lower end of the swing rod 8. The upper end of the swing rod 8 is rotatably connected to the ear plate 9 through a pin. The ear plate 9 is fixed inside the furnace body. The pin, the arc-shaped rod 7 and the arc-shaped tube 6 are concentric. A top cover 4 is detachably fixedly connected to the upper end of the furnace body. A top hole 11 is opened on one side of the top cover 4. A winch 12 is fixed to the upper end of the top cover 4. The wire rope 10 of the winch 12 passes through the top hole 11 and is fixedly connected to the swing rod 8.

[0026] When the winch 12 is started, the wire rope 10 is wound up. The swing arm 8 drives the arc rod 7 to rotate, causing the arc rod 7 to exit from the arc tube 6, allowing the molten lead in the furnace to flow out through the arc tube 6. When the winch 12 is started, the wire rope 10 is unwound. Under the gravity of the arc rod 7, the swing arm 8 and the arc rod 7 rotate, allowing the arc rod 7 to enter the arc tube 6. At the same time, the arc rod 7 is cleared, preventing impurities in the molten lead from clogging the arc tube 6.

[0027] Because one end of the arc-shaped rod 7 inside the furnace is bent upwards, impurities that settle in the lower layer of the lead liquid inside the furnace cannot flow out through the arc-shaped pipe 6, thus maintaining the purity of the lead liquid flowing out from the arc-shaped pipe 6.

[0028] A storage tank 26 is fixed on the outside of the furnace body. One end of the arc-shaped pipe 6 on the outside of the furnace body is connected to the storage tank 26. An outlet pipe 27 is fixedly connected to the storage tank 26, and a valve 28 is installed on the outlet pipe 27.

[0029] By setting up a storage tank 26 and installing a valve 28 on the outlet pipe 27 of the storage tank 26, the outflow of lead liquid can be easily controlled by controlling the opening degree of the valve 28.

[0030] The furnace body is equipped with a lower heating element and an upper heating element at its lower and upper ends, respectively. This device, by incorporating the upper and lower heating elements, enables rapid heating of the recycled lead raw materials entering the furnace body.

[0031] Specifically, the lower heating assembly includes an electric heating tube 5 fixed inside the lower end of the furnace body.

[0032] The upper heating assembly includes a cover plate 18, on which a connecting pipe 16 is eccentrically connected. The connecting pipe 16 movably passes through the cover plate 18 and is perpendicular to it. A branch pipe 24 perpendicular to the lower end of the connecting pipe 16 is fixedly connected to the lower end of the branch pipe 24, and multiple burners 25 are fixedly connected to the lower end of the branch pipe 24. A portion of the connecting pipe 16 below the cover plate 18 passes through an inlet hole 13 on the upper cover 4, and another portion of the connecting pipe 16 below the cover plate 18 movably passes through a connecting plate 17. The connecting plate 17 is fixed inside one side of the inlet hole 13. A vertical cylinder 19 is fixed at the upper end of the 8. An upper plate 20 is fixed on the telescopic rod of the cylinder 19. The upper plate 20 is rotatably connected to the upper end of the connecting pipe 16. A motor 21 is fixed at the upper end of the upper plate 20. The output shaft of the motor 21 is concentrically fixedly connected to the upper end of the connecting pipe 16. A rotating sleeve 22 is rotatably and sealingly connected to the connecting pipe 16 between the upper plate 20 and the cover plate 18. The rotating sleeve 22 is connected to the connecting pipe 16 and fixedly connected to the upper plate 20. A flexible hose 23 is fixedly connected to the rotating sleeve 22.

[0033] Rotate the cover plate 18 to misalign it with the inlet hole 13, thus facilitating the feeding of recycled lead raw materials into the furnace. Activating the electric heating element 5 heats the recycled lead raw materials at the lower end of the furnace interior.

[0034] The gas flows through hose 23, rotating sleeve 22, connecting pipe 16, and branch pipe 24 before being ejected from nozzle 25. Igniting the gas from nozzle 25 heats the upper part of the recycled lead material within the furnace. Starting cylinder 19 allows the upper plate 20, motor 21, rotating sleeve 22, connecting pipe 16, branch pipe 24, and nozzle 25 to move vertically, bringing the nozzle 25 closer to the recycled lead material and improving heating efficiency. Starting motor 21 allows the connecting pipe 16, branch pipe 24, and nozzle 25 to rotate, and the flame from nozzle 25 provides uniform heating to the upper part of the recycled lead material within the furnace, further enhancing heating efficiency.

[0035] A solenoid valve 15 is installed on the hose 23, and a gas concentration sensor 14 is fixed at the lower end of the upper cover 4. The gas concentration sensor 14, the controller, and the solenoid valve 15 are electrically connected.

[0036] When the flame goes out and the gas concentration in the furnace exceeds the standard, the gas concentration sensor 14 sends a signal to the controller, and the controller closes the solenoid valve 15 to prevent an explosion caused by excessive gas in the furnace.

[0037] Example 2: Based on Example 1, refer to 1 and Figure 2As shown in the figure, the furnace body includes an inner shell 3 and an outer shell 1. A heat-conducting metal plate 29 is fixed between the inner shell 3 and the outer shell 1 at the arc-shaped tube 6. The heat-conducting metal plate 29 is in close contact with the outer wall of the inner shell 3 and the inner wall of the outer shell 1. The arc-shaped tube 6 passes through the heat-conducting metal plate 29, allowing the outer shell 1 and the inner shell 3 to conduct heat to the storage tank 26 through the heat-conducting metal plate 29. Specifically, refractory cement 2 is filled between the inner shell 3 and the outer shell 1.

[0038] The refractory cement 2 filling the space between the inner shell 3 and the outer shell 1 can insulate the furnace body. The outer shell 1 and the inner shell 3 can conduct heat to the storage tank 26 through the heat-conducting metal plate 29, which can prevent the lead liquid in the storage tank 26 from cooling and solidifying.

[0039] 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.
