Description

Technical Field

[0001] The utility model relates to the technical field of secondary lead smelting equipment, in particular to a secondary lead smelting furnace. Background Art

[0002] With the development of the national economy, the use of lead is increasing, and the consumption and scrapping of lead-acid batteries are increasing. How to efficiently and environmentally recycle waste lead-acid batteries, especially the treatment of lead sludge and lead paste in waste batteries, has attracted widespread attention. The production process of recycled lead is to melt the metal waste in the lead-acid battery through a metal smelting furnace, and then synthesize recycled lead.

[0003] The existing method for smelting metal scraps is to place the metal scraps in a smelting box of a metal smelting furnace, and then the metal smelting furnace smelts the metal scraps in the smelting box. After the smelting is completed, the smelting box needs to be manually lifted out of the metal smelting furnace through a lifting device, and then the molten metal in the smelting box is poured out. However, it is difficult to manually operate the lifting device, and the lifting device has a complex structure, is easily damaged, and has a high cost.

[0004] In the published Chinese patent application, the publication number is CN217733230U, and the patent name is: an energy-saving and environmentally friendly recycled lead multi-chamber metal smelting furnace. The prior art puts the metal waste into the smelting box, and then the smelting furnace body smelts the metal waste in the smelting box. After the smelting of the metal waste in the smelting box is completed, the two sets of hydraulic cylinders are opened, and the two sets of hydraulic rods drive the two sets of extension plates to move downward under the hinge of four sets of articulated frames, four sets of articulated blocks and four sets of articulated shafts. The two sets of extension plates drive the smelting box to move upward under the constraint of the hinge, and the metal waste melt in the smelting box is introduced into the material guide channel through the pouring nozzle, and then the metal waste melt in the material guide channel is introduced into the next process for processing. Although the prior art can solve the above problems through the above scheme. However, in the prior art, when pouring the molten metal, the smelting box as a whole is moved, and the molten metal is poured into the material guide channel during the movement, which easily causes the molten metal to shake violently in the smelting box, and there is a risk of the molten metal tipping over and spilling. Therefore, in order to solve the problem of tipping over and spilling of the recycled lead molten metal in the prior art, the present application is proposed to solve the problem.

[0029] Embodiment 1

[0030] See also Figure 1 to Figure 2 The utility model provides a technical solution: a secondary lead smelting furnace, including a support plate 1, a high-temperature component, a driving component, a material receiving component and a furnace body 7 for holding secondary lead raw materials, two symmetrically arranged rotating shafts are fixedly connected to the outer wall of the furnace body 7, and the furnace body 7 is rotatably connected to the support plate 1 through the rotating shaft.

[0031] The support plate 1 is used to support the furnace body 7. The high temperature component is used to heat the furnace body 7 as a whole. After the furnace body 7 is heated up, the recycled lead raw material inside is melted. The driving component is used to drive the furnace body 7 to rotate around the rotating axis at a certain angle so that the furnace body 7 can dump the recycled lead melt. The receiving component is used to receive the recycled lead melt.

[0032] The high temperature component includes a boiler burner 8 , which is disposed on the support plate 1 and is located below the furnace body 7 .

[0033] The boiler burner 8 is used to generate a heat source and heat the furnace body 7 to increase the temperature.

[0034] The driving assembly includes a worm wheel 2, a worm 4 and a servo motor 6. The worm wheel 2 is fixedly mounted on a rotating shaft, the servo motor 6 is fixedly mounted on a side wall of the support plate 1, and the output shaft of the servo motor 6 is transmission-connected to the worm 4 through a coupling, and the helical teeth of the worm 4 are meshed with the teeth of the worm wheel 2.

[0035] Among them, the first fixed plate 3 and the second fixed plate 5 are fixedly connected to the outer wall of the support plate 1, and the two ends of the worm 4 are rotatably connected to the first fixed plate 3 and the second fixed plate 5 respectively. The output shaft of the servo motor 6 is connected to the worm 4 through a coupling, and the servo motor 6 is fixedly installed on the outer wall of the support plate 1. The servo motor 6 is used to drive the worm 4 to rotate. After the servo motor 6 is started, the worm 4 is driven to rotate through the coupling, and the spiral teeth on the worm 4 drive the worm wheel 2 to rotate. Since the worm wheel 2 is fixedly connected to the furnace body 7 through the rotating shaft, when the worm wheel 2 rotates, the furnace body 7 rotates a certain angle with the rotating shaft as the center, so that the furnace body 7 is tilted.

[0036] The material receiving assembly comprises a material receiving hopper 9 and a support frame 13 . The material receiving hopper 9 is slidably arranged on the support frame 13 . After sliding, the material receiving hopper 9 is located at one side of the furnace body 7 and can receive the recycled lead poured out of the furnace body 7 .

[0037] The receiving hopper 9 is used to hold the recycled lead melt. After the smelting is completed, the receiving hopper 9 slides close to the furnace body 7, and the receiving hopper 9 receives the melt poured out of the furnace body 7 in time.

[0038] Specifically, the material receiving assembly also includes an electric push rod 12, which is installed on a support frame 13, and the piston shaft end of the electric push rod 12 is detachably connected to the material receiving hopper 9.

[0039] The electric push rod 12 is used to push and pull the receiving hopper 9, so that the receiving hopper 9 slides on the support frame 13, and the receiving hopper 9 slides close to or away from the furnace body 7.

[0040] More specifically, the piston shaft end of the electric push rod 12 is fixedly connected to the first clamping block 10, and the side wall of the hopper 9 is fixedly connected to the second clamping block 11, and the first clamping block 10 and the second clamping block 11 are detachably connected. One end of the support frame 13 is fixedly connected to the support plate 1.

[0041] The first clamping block 10 is clamped with the second clamping block 11. The cooperation between the first clamping block 10 and the second clamping block 11 facilitates the disassembly of the receiving hopper 9.

[0042] Specifically, a secondary lead smelting furnace also includes a control panel, which is electrically connected to the boiler burner 8, the electric push rod 12, and the servo motor 6 respectively.

[0043] Among them, the control board is used to control the start and stop of the boiler burner 8 and the electric push rod 12. The control board can adopt an editable logic controller. The control board is equipped with a logic control program and a timing control program to meet the control requirements of the boiler burner 8 and the electric push rod 12.

[0044] When in use, first put the metal waste into the furnace body 7, then start the boiler burner 8 through the control panel to heat the furnace body 7, so as to melt the metal waste in the furnace body 7. After the metal waste in the furnace body 7 is melted, start the servo motor 6 and the electric push rod 12, the servo motor 6 drives the worm 4 to rotate clockwise, and the worm 4 drives the worm wheel 2 to rotate clockwise, so that the furnace body 7 turns clockwise. During the clockwise turning of the furnace body 7, the electric push rod 12 continuously pushes the receiving hopper 9, and the receiving hopper 9 moves to the bottom of the opening of the furnace body 7. As the inclination angle of the furnace body 7 increases, the solution in the furnace body 7 is poured into the receiving hopper 9. After emptying, the control panel controls the output shaft of the servo motor 6 to rotate counterclockwise, and at the same time, the control panel controls the piston rod of the electric push rod 12 to retract. At this time, the receiving hopper 9 can be directly inserted into the hole of the receiving hopper 9 with the help of an external tool, and then the receiving hopper 9 is pulled upward to make the first clamping block 10 disengage from the second clamping block 11, and the receiving hopper 9 can be directly taken out, and the next process can be directly moved to, so that it is convenient to use.

When the furnace body 7 is turned over, the rotating shaft is also in a rotating state, and the rotating shaft drives the second connecting rod 17 to rotate (rotate a certain angle), and the second connecting rod 17 drives the first connecting rod 16 to move. When the first connecting rod 16 moves, the sliding plate 15 is pulled to slide on the support frame 13. The sliding plate 15 slides to push (or pull) the receiving hopper 9 close to (or away from) the furnace body 7.

[0048] When in use, first put the metal waste into the furnace body 7, then start the boiler burner 8 to heat the furnace body 7, so as to melt the metal waste in the furnace body 7. After the metal waste in the furnace body 7 is melted, start the servo motor 6, the servo motor 6 drives the worm 4 to rotate clockwise, the worm 4 drives the worm wheel 2 to rotate clockwise, so that the furnace body 7 turns clockwise. During the clockwise turning of the furnace body 7, the furnace body 7 will drive the second connecting rod 17 to rotate clockwise. During the rotation of the second connecting rod 17, the first connecting rod 16 will be pulled to move, thereby driving the sliding plate 15 to move in the direction of the furnace body 7. During the gradual turning of the furnace body 7, the position of the receiving hopper 9 will always be at the discharge position of the furnace body 7, so that the receiving process is more accurate and the solution will not spill. When the solution in the furnace body 7 is poured out, the servo motor 6 is turned over, and during the resetting of the furnace body 7, the receiving hopper 9 will also move away from the furnace body 7. At this time, the receiving hopper 9 can be directly inserted into the hole of the receiving hopper 9 with the help of an external tool, and then the receiving hopper 9 can be pulled upward to disengage the first clamping block 10 from the second clamping block 11, so that the receiving hopper 9 can be directly taken out and the next process can be directly moved to.
