Description

Technical Field

[0001] This invention relates to the field of lead-acid battery production equipment, and in particular to a device for dredging lead slag from lead pots used in lead-acid battery production. Background Technology

[0002] In the production process of lead-acid battery grids, lead ingots need to be melted into molten lead in a lead pot. During this process, the surface of the molten lead oxidizes and accumulates a layer of slag, mainly composed of lead oxide, impurities, and other metal oxides, collectively known as lead slag. If this lead slag is not removed in time, it will affect the quality of subsequent grid casting, resulting in a loose grid structure that is prone to breakage, seriously affecting battery performance and lifespan.

[0003] Currently, the removal of lead slag from lead pots mainly relies on manual labor. Workers use simple strainers or shovels with long handles to work in harsh environments with high temperatures (usually exceeding 330°C) and harmful lead vapors.

[0004] Relying entirely on manpower results in slow salvage speeds, which cannot meet the needs of continuous production. People are exposed to high-temperature molten lead and harmful gases at close range, posing risks of burns and occupational health hazards. Summary of the Invention

[0005] This invention provides a device for dredging lead slag from lead-acid battery production pots, which can solve the problem of slow dredging speed due to complete reliance on manual labor in the prior art.

[0006] A lead slag removal device for lead-acid battery production includes a horizontally movable lead slag scraper inside the lead pot. A vertically movable lead slag baffle is located at one end of the lead pot, dividing the interior into a working area and a lead slag enrichment area. In its natural state, the bottom of the lead slag baffle is below the liquid surface, and the top of the baffle protrudes above the liquid surface. During lead slag removal, the lead slag scraper is moved from the working area to the lead slag enrichment area, driving the lead slag above the liquid surface into the enrichment area.

[0007] Furthermore, the lead slag scraper and the lead slag baffle are respectively provided with a C-shaped surface one and a C-shaped surface two that cooperate with each other; in the natural state, part of the C-shaped surface one extends below the liquid surface; and part of the C-shaped surface two protrudes from above the liquid surface.

[0008] Furthermore, flexible hanging components are connected to both ends of the upper surface of the lead slag scraper, and the ends of the flexible hanging components are connected to a crossbeam; One side of the crossbeam is connected to a telescopic component that drives it to move in the horizontal direction.

[0009] Furthermore, the flexible suspension component includes steel wire, chain, or rope; the telescopic component includes telescopic cylinder, electric telescopic cylinder, or telescopic hydraulic cylinder.

[0010] Furthermore, an anti-deviation rod is provided on the bottom side of the crossbeam, and an anti-deviation sleeve for inserting the anti-deviation rod is provided on the upper surface of the lead slag scraper, with the bottom end of the anti-deviation rod inserted into the anti-deviation sleeve.

[0011] Furthermore, the two ends of the lead slag baffle away from the working area are respectively connected to connecting frames, and the top of the connecting frame is connected to a connecting crossbar. The end of the connecting crossbar protrudes from the side wall of the lead pot. Two fixing seats are fixed on the side wall of the lead pot. A vertical rod is fixed on the upper surface of the fixing seat, and a crossbeam is fixed on the top of the two vertical rods. The vertical section of the connecting frame is located on the corner side of the lead pot. A spring is fixed on the bottom side of the crossbeam located around the vertical rod. The end of the spring is connected to a convex ring that moves up and down along the outer wall of the vertical rod. The end of the connecting crossbar is fixed on the convex ring.

[0012] Furthermore, it also includes a salvage mechanism, which includes a salvage box. The salvage box has a feed inlet and a filter hole 1 on its adjacent side walls, and a filter hole 2 is provided at the bottom of the salvage box. An operating rod is detachably installed on one side of the salvage box.

[0013] Furthermore, two outer walls of the lead pot are respectively provided with fixing blocks, the upper surface of the fixing blocks is fixed with a support column, the top of the support column is fixedly connected to a mounting seat, a pair of sliding rods are connected between the two mounting seats, and a slider is provided on the pair of sliding rods. The bottom side of the slider is connected to a support frame for supporting the retrieval box through a hanging rod; the support frame includes a base plate, the upper surface of the base plate is provided with positioning protrusions on both the peripheral edge sides, and the peripheral side wall of the retrieval box is provided with positioning rings that cooperate with the positioning protrusions.

[0014] Furthermore, a protrusion is provided on each of the two sides of the top of the retrieval box, and a rectangular through hole is provided on the protrusion.

Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] To address the problems of low efficiency and dangerous working environment in manual lead slag retrieval in existing technologies, this invention aims to provide a mechanized and partially automated lead slag retrieval device to improve retrieval efficiency and reduce the risk of direct contact between manual workers and molten lead and harmful gases.

[0021] The present invention provides a lead slag retrieval device for lead pots in lead-acid battery production. A lead slag baffle 11 that can move up and down is set at one end inside the lead pot 1. In its natural state, the bottom end of the baffle 11 is below the surface of the lead liquid, and the top end protrudes from above the liquid surface, thereby dividing the interior of the lead pot 1 into two parts: a "working area" and a "lead slag enrichment area".

[0022] To effectively drive the lead slag from the work area to the lead slag enrichment area, this invention includes a lead slag scraper 2 that can move horizontally within the lead pot 1. The bottom end of the scraper 2 is also located below the liquid surface. During the dredging operation, the lead slag scraper 2 is controlled to move horizontally from the work area to the lead slag enrichment area. During its movement, the scraper 2 pushes the lead slag above the liquid surface to the lead slag enrichment area, achieving mechanized collection of the lead slag. Then, concentrated lead slag dredging operations are carried out in the lead slag enrichment area, improving efficiency and reducing labor intensity.

[0023] To ensure that the lead slag scraper 2 effectively pushes the lead slag through the lead slag baffle 11 into the enrichment zone when it moves to the lead slag baffle 11, and to prevent a large amount of lead slag above the liquid surface from returning to the working area when the scraper 2 returns to pass through the baffle 11, this invention provides mutually cooperating C-shaped surfaces 20 and 10 on the opposite end faces of the scraper 2 and the baffle 11, respectively. In its natural state, part of C-shaped surface 20 extends below the liquid surface, and part of C-shaped surface 10 protrudes above the liquid surface. Through the cooperation of C-shaped surfaces 20 and 10, the scraper 2 and the baffle 11 can form a good fit when in contact, which is beneficial for pushing all the lead slag into the enrichment zone. By utilizing C-shaped surfaces 20 and 10 to transmit force, the scraper 2 moves and compresses the baffle 11 downwards.

[0024] To enable the horizontal movement of the lead slag scraper 2 and adapt to high-temperature environments, this invention employs flexible suspension components 21, such as steel wires, chains, or ropes, to connect the two ends of the upper surface of the lead slag scraper 2. The ends of the flexible suspension components 21 are connected to a crossbeam 22. A telescopic component 23, which drives the horizontal movement of the crossbeam 22, is connected to one side of the crossbeam 22. By using the flexible suspension components 21 and mechanical drive technology, the scraper can be stably suspended and its movement precisely controlled above the lead pot, achieving automated or semi-automated operation. This isolates the operator from the high-temperature molten lead, improving safety.

[0025] To prevent the lead slag scraper 2 from swaying or deflecting during horizontal movement, an anti-deviation rod 221 is installed on the bottom side of the crossbeam 22, and an anti-deviation sleeve 201 is installed on the upper surface of the lead slag scraper 2 for inserting the anti-deviation rod 221. The guide structure formed by the combination of the anti-deviation rod 221 and the anti-deviation sleeve 201 can effectively constrain the scraper to move horizontally only along a predetermined path, thereby improving the stability and reliability of the slag scraping operation.

[0026] To enable the lead slag baffle 11 to move up and down and ensure its effective division of areas, the present invention connects the lead slag baffle 11 to an elastic lifting mechanism via a connecting frame 12 and a connecting crossbar 120. Specifically, the end of the connecting crossbar 120 protrudes from the side wall of the lead pot 1 and is fixed to a protruding ring 44 that can move up and down along the outer wall of the vertical rod 41. The protruding ring 44 is connected to a crossbeam 42 fixed to the top of the vertical rod 41 via a spring 43. When the C-shaped surface 20 and the C-shaped surface 10 are pressed against each other, the lead slag scraper 2 drives the lead slag baffle 11 to move downward under the action of gravity, and the spring 43 is stretched. When the C-shaped surface 20 and the C-shaped surface 10 separate, the lead slag baffle 11 moves upward and returns to its natural state under the rebound action of the spring 43.

[0027] To facilitate safe and labor-saving salvage operations, an operating rod 6 is detachably installed on one side of the salvage box 5. The operating rod 6 includes a rod body 60, with a limiting part 61 at the end of the rod body 60. One side of the limiting part 61 is connected to an insert rod 62 that passes through two rectangular through holes 56. The upper surface of the end of the insert rod 62 has an upwardly protruding part 63. The included angle between the rod body 60 and the limiting part 61 is 90°-150°. The operating rod 6 is inserted into the rectangular through hole 56 of the protrusion 55 on the top of the salvage box via the insert rod 62, and is fixed and limited by the limiting part 61 and the protruding part 63. The use of a long rod operating tool that can be quickly disassembled and assembled allows operators to carry out salvage operations away from the lead pot, further ensuring personnel safety and reducing labor intensity.

[0028] To remove the lead slag concentrated in the lead slag enrichment area from the lead pot, this invention also includes a specialized retrieval mechanism. This mechanism comprises a retrieval box 5, with an inlet 51 and a first filter hole 52 on its adjacent side walls, and a second filter hole 53 at the bottom. By using the retrieval box 5 with the first and second filter holes 53, when scooping up the lead molten slag, the molten lead can flow back to the lead pot 1 through the first and second filter holes 53, while the solid lead slag is retained inside the box, thus achieving the separation of lead slag from the lead molten slag.

[0029] To facilitate control of the retrieval box 5 moving horizontally at the same height, fixing blocks 13 are respectively provided on the two outer walls of the lead pot 1. A support column 14 is fixed on the upper surface of the fixing block 13, and a mounting seat 15 is fixedly connected to the top of the support column 14. A pair of sliding rods 16 are connected between the two mounting seats 15. A slider 17 is fitted on the pair of sliding rods 16. The bottom side of the slider 17 is connected to a support frame for supporting the retrieval box 5 through a hanging rod 18. The support frame includes a base plate 7. The upper surface of the base plate 7 is equipped with positioning protrusions 71 on both the peripheral edges. The peripheral side wall of the retrieval box 5 is provided with positioning rings 54 that cooperate with the positioning protrusions 71. The operator can move the retrieval box 5 by pushing the slider 17, so that it can move and be positioned precisely above the lead pot 1. The retrieval is more labor-saving and stable, especially suitable for situations where frequent retrieval is required or the retrieval box 5 is heavy.

[0030] To facilitate adjustment of the immersion depth of the retrieval box 5 according to the liquid level, a rod sleeve 19 is provided through the slider 17, and the lifting rod 18 passes through the rod sleeve 19. The rod sleeve 19 is provided with locking bolts to fix the lifting rod 18.

[0031] When lead slag needs to be retrieved, the drive telescopic component 23 is activated, causing the crossbeam 22 and the lead slag scraper 2, suspended by the flexible hanging component 21, to move horizontally from the working area to the lead slag enrichment area within the lead pot. The bottom end of the scraper 2 is below the liquid surface, pushing the lead slag floating on the surface towards the enrichment area during its movement. When the scraper 2 contacts the baffle 11, its C-shaped surface 20 at its end engages with the C-shaped surface 10 on the baffle 11, forcing the baffle 11 to move downwards against the tension of the spring 43, allowing the scraper 2 to smoothly push the lead slag past the baffle into the enrichment area. After the scraper 2 passes, the baffle 11 resets under the action of the spring 43, preventing the lead slag from flowing back.

[0032] After the lead slag accumulates in the enrichment zone, it is retrieved using a retrieval box 5. The operator places the retrieval box 5 on the base plate 7 of the support frame, securing it with the positioning protrusion 71 and positioning ring 54. By pushing the slider 17 along the sliding rod 16, the operator controls the movement of the retrieval box 5 above the liquid surface in the enrichment zone. The feed inlet 51 on the side of the retrieval box 5 is submerged in molten lead, and the lead slag enters the box along with the molten lead. The molten lead flows back to the lead pot through the filter holes 52 on the box wall and 53 at the bottom, while the lead slag is retained. Once full, the operating rod 6 is attached, with its insertion rod 62 inserted into the rectangular through hole 56 of the protrusion 55 for fixation. The retrieval box 5 is then removed from a safe location away from the lead pot, and the lead slag is cleaned, completing one retrieval operation.

[0033] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
