Description

Technical Field

[0001] The utility model relates to the technical field of lead refining, in particular to a copper removal device for refined lead production. Background Art

[0002] The recycling of scrap lead-acid batteries accounts for a significant portion of the secondary lead production process. Traditional methods for producing refined lead from scrap batteries involve fire refining. During this process, some methods add additives to the furnace during copper removal, causing the molten lead, copper-containing layer, and slag to separate into separate layers within the furnace, which are then discharged through different discharge ports. Other methods also add additives to the furnace, causing the molten lead, copper-containing layer, and slag to separate into separate layers within the furnace. The furnace temperature is then lowered, allowing the copper-containing layer and slag to form a copper-containing slag, which is then removed.

[0003] Patent document CN213086064U discloses a copper removal device for refined lead production. While this device is suitable for small-scale production, the device described in the patent arranges the collection trough and screen plate in an inclined structure. This is intended to allow the collected copper-containing slag to automatically enter the rotating shaft for discharge. However, because both the collection trough and screen plate are arranged at an angle, when the thickness of the copper-containing slag in the upper layer of liquid lead is relatively large, the upwardly tilted collection trough and screen plate cannot penetrate the copper-containing slag layer and enter the liquid lead layer. As the screen plate and collection trough rotate with the rotating shaft, the upper layer of copper-containing slag cannot be effectively collected. Furthermore, the collection trough described in the patent has a U-shaped cross-section. Therefore, when the screen plate and collection trough are moved upward, a large amount of liquid lead remains in the collection trough, resulting in serious waste of liquid lead.

[0004] The patent document with publication number CN219279991U discloses a copper removal device for refined lead production. During operation, recycled lead is put into the furnace body, and then the recycled lead in the furnace body is heated. When it is necessary to collect the copper-containing slag on the upper layer of the lead liquid in the furnace body, the upper telescopic cylinder is started to make the sliding sleeve and the slag collection device move downward, and the collection plate is located in the lead liquid in the lower layer. Then the motor is started to rotate the rotating tube. During the rotation of the rotating tube, the filter plate collects the copper-containing slag on the upper layer. When the rotating tube rotates a set number of times, the upper telescopic cylinder is started to make the sliding sleeve and the slag collection device move upward, and the copper-containing slag will fall onto the collection plate, and the lead liquid on the collection plate can flow out through the filter plate. As the sliding sleeve moves upward, when the through hole is connected to the opening, the vibration motor is started. The vibration motor can vibrate the rotating tube and the slag collection device. Under the guidance of the guide surface, the copper-containing slag on the collection plate will pass through the through hole and the opening into the rotating tube and then be discharged. When the lead liquid in the furnace needs to be discharged, the inner wall of the inner sleeve is cleaned, and then the lower telescopic cylinder is activated, causing the telescopic rod of the lower telescopic cylinder to drive the inner sleeve downward. Once the discharge is connected to the rotating tube, the lead liquid in the furnace can enter the rotating tube through the discharge hole and be discharged. In this device, the lead liquid and copper slag are both discharged through the inner sleeve, so the inner sleeve must be cleaned before the lead liquid is discharged, which is quite troublesome during use.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1: Reference Figure 1-Figure 2 As shown, the copper removal device for refined lead production includes a jacketed tank 1, the lower end of which is fixedly connected to a lower pipe 5, a heating pipe 14 fixed in the interlayer of the jacketed tank 1, and an inlet pipe 4 fixedly connected to the upper end of the jacketed tank 1. The heating pipe 14 can heat the lead in the tank.

[0025] A stirring rod 3 is rotatably provided in the jacketed tank 1, and a motor 2 connected to the stirring rod 3 is fixed to the upper end of the jacketed tank 1. After starting the motor 2, the stirring rod 3 rotates, and the stirring rod 3 can stir the lead liquid in the jacketed tank 1.

[0026] An annular groove 6 is provided in the jacketed tank 1 for sliding in the vertical direction. The outer side of the annular groove 6 is in sliding contact with the inner wall of the jacketed tank 1 . The height of the vertical part inside the annular groove 6 is lower than the height of the vertical part outside the annular groove 6 .

[0027] The jacketed tank 1 is provided with a driving assembly capable of driving the annular groove 6 to move up and down in the jacketed tank 1 .

[0028] The driving assembly includes a support rod 15, the lower end of the support rod 15 is fixed in the annular groove 6, and the upper end of the support rod 15 is connected to the upper end of the jacket tank 1 through a telescopic rod 16. The telescopic rod 16 is a high temperature resistant cylinder.

[0029] The lower end of the annular groove 6 is fixedly connected to a plurality of vertical connecting pipes 7. The lower ends of the connecting pipes 7 are slidingly and sealingly inserted into the vertical portion of the outlet pipe 8. The lower end of the vertical portion of the outlet pipe 8 is fixedly connected to a straight portion. The straight portion of the outlet pipe 8 extends through the side wall of the jacketed tank 1 on one side. The outlet end of the straight portion of the outlet pipe 8 is connected to the filter assembly, which is in turn connected to the annular sleeve 11. Specifically, the filter assembly includes a connecting box 9 with an open lower end. The upper end of the annular sleeve 11 inside the connecting box 9 is provided with holes, and the holes are fixed in the holes. The filter screen 12 is fixed in the holes. The side of the connecting box 9 away from the jacketed tank 1 is removably fixed and sealed with a sealing plate 10.

[0030] The annular sleeve 11 is fixed on the outside of the jacketed tank 1 , and the lower end of the annular sleeve 11 is fixedly connected to a discharge pipe 13 , on which a valve is installed.

[0031] During operation, a copper removal agent is added to the lead liquid in the jacketed tank 1 through the inlet pipe 4, and the motor 2 is started, which drives the stirring rod 3 to rotate and stir the lead liquid in the jacketed tank 1. After stirring the lead liquid for a period of time, copper slag will float on the upper end of the lead liquid.

[0032] According to the liquid level of the lead liquid in the jacketed tank 1, the annular groove 6 is moved downward by the telescopic rod 16 and the support rod 15, so that the upper layer of the lead liquid and the copper slag enter the annular groove 6. Since the height of the vertical portion inside the annular groove 6 is lower than the height of the vertical portion outside the annular groove 6, the lead liquid can enter the annular groove 6 more easily.

[0033] As the annular groove 6 descends, the connecting pipe 7 moves into the vertical portion of the outlet pipe 8. The upper layer of molten lead and copper slag enter the annular groove 6 and are then discharged through the connecting pipe 7 and the outlet pipe 8. The molten lead and copper slag discharged from the outlet pipe 8 enter the connecting box 9. The molten lead then flows through the filter screen 12 into the annular sleeve 11, while the copper slag is intercepted by the filter screen 12 and retained in the connecting box 9. Opening the sealing plate 10 facilitates the discharge of the lead slag from the connecting box 9.

[0034] Example 2: Based on Example 1, refer to Figure 1 As shown, the inner wall of the ring sleeve 11 is in close contact with the outer wall of the jacketed tank 1, and the outer side of the jacketed tank 1 above and below the ring sleeve 11 is covered with a heat-insulating sleeve, and the outer side of the ring sleeve 11 is covered with a heat-insulating sleeve.

[0035] The lead liquid with the lead residue filtered out flows into the ring sleeve 11, which is fixed to the outside of the jacketed tank 1, and the inner wall of the ring sleeve 11 is in close contact with the outer wall of the jacketed tank 1. The heat of the jacket tube can be transferred to the ring sleeve 11, which can prevent the lead liquid in the ring sleeve 11 from cooling and solidifying.

[0036] By arranging heat-insulating sleeves on the outer side of the jacketed tank 1 above and below the annular sleeve 11 and arranging heat-insulating sleeves on the outer side of the annular sleeve 11, heat loss can be reduced during the copper removal process of refined lead.

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