[0002] In the process of manufacturing lead-acid batteries, lead blocks need to be melted into lead liquid, which is used for casting welding. The process of making lead liquid requires the lead slag in the lead pot to be salvaged, which contains lead ash and clear lead. In order to reduce costs, the clear lead (particles) needs to be screened out and returned to the furnace for further use, while the clear lead needs to be screened out from the lead slag.

DETAILED DESCRIPTION

[0022] like Figures 1 to 3 As shown, a lead slag separator is used to separate lead slag from lead liquid in the production process of lead-acid batteries, and the lead slag contains lead ash and clear lead. The lead slag separator includes a bracket 1, a screening frame 2 and a driving mechanism.

[0023] The screening frame 2 is arranged on the bracket 1. The screening frame 2 is a frame structure with a top surface as a whole. A feed port 21 is provided on one side of the top surface of the screening frame 2. The feed port 21 is a bell mouth, which is convenient for feeding. The bottom surface of the screening frame 2 is provided with a screen 22. Screen holes are arranged at intervals on the screen 22. The diameter of the screen holes is 5 to 10 mm, and the spacing between the screen holes is 10 to 20 mm. A lead outlet 23 is also provided on the bottom surface of the screening frame 2 away from the feed port 21; a lead ash receiving bucket 3 for collecting lead ash is provided below the screen 22, and a lead receiving bucket 4 for receiving lead is provided below the lead outlet 23.

[0024] Since the coverage area of ​​the screen 22 is large, in order to facilitate the collection of lead ash, the screening frame 2 is provided with a collecting baffle 24 below the screen 22, and a lead ash outlet 25 is provided in the middle of the collecting baffle 24. The collecting baffle 24 is inclined downward from the periphery to the middle lead ash outlet 25, so that the lead ash falling from the periphery of the screen 22 can first fall on the collecting baffle 24, and then slide to the lead ash outlet 25 and fall into the lead ash receiving bucket 3.

[0025] The bracket 1 is provided with a horizontal guide rail 11. The guide rail 11 includes two groups located on both sides of the vertical movement direction of the screening frame 1, each group of the guide rail 11 includes an upper limit plate 12 and a lower limit plate 13, and the gap between the upper limit plate 12 and the lower limit plate 13 forms the guide rail 11 for guiding.

[0026] A pulley 5 moving along the guide rail 11 is provided below the bottom surface of the screening frame 2. The pulley 5 includes at least two groups, each group of pulleys 5 is cylindrical with both ends passing through one side of the guide rail 11, and both ends of the pulley 5 are provided with limit baffles 51 at the parts extending out of the guide rail 11 to prevent the pulley 5 from escaping from the guide rail 11.

[0027] The bottom surface of the screening frame 2 has a limit slot 29 mounted on the pulley 5 .

[0028] The driving mechanism is arranged on the bracket 1, and the driving mechanism drives the screening frame 2 to move back and forth along the guide rail 11. The driving mechanism includes an eccentric wheel 7 driven to rotate by a motor 6. A driving rod 26 is arranged on one side of the screening frame 2, and a driving ring 27 is arranged at the end of the driving rod 26. The eccentric wheel 7 extends into the driving ring 27 and drives the driving ring 27 to move back and forth.

[0029] In a preferred embodiment, the driving rod 26 includes two sections, and the two sections are hinged by a rotating shaft 28 of the horizontal and vertical driving rod 26. Therefore, since the screening frame 2 is kept in a horizontal state under the action of gravity, the section of the driving rod 26 connected to the driving ring 27 can move up and down driven by the eccentric wheel 7 in addition to moving in the horizontal direction. The two-section driving rod 26 design can avoid the influence of the possible up and down movement of the driving ring 27 caused by the eccentric wheel 7 on the screening frame 2.

[0030] When the lead slag separator of the utility model is working, the lead slag fished out in the process of preparing lead liquid is put into the screening frame 2 from the feed port 21, the eccentric wheel 7 is driven by the motor 6 to rotate, the eccentric wheel 7 drives the driving ring 27 to move horizontally, and the driving rod 26 drives the screening frame 2 to move horizontally back and forth. During the horizontal back and forth movement of the screening frame 2, the lead ash with smaller particles falls from the sieve holes of the screen 22 and is collected by the lead ash receiving bucket 3; the clear lead with larger particles that has not fallen from the sieve holes of the screen 22 slowly moves to the clear lead outlet 23 on the other side and is collected by the clear lead receiving bucket 4.

[0031] The utility model screens by shaking back and forth, and is suitable for separating and recovering clear lead from lead slag fished out in the process of preparing lead liquid.
