Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lead-acid battery manufacturing devices, and particularly relates to a lead slag filtering device. Background Art
[0002] When producing lead strip for lead-acid battery plates, the process typically involves melting a lead alloy, casting the molten lead alloy into a strip, and then cold-rolling the strip. However, this process has drawbacks: during the melting process, the alloying elements oxidize and burn away, producing lead slag. This slag, when carried along with the molten lead, enters the strip and, when rolled, can damage the strip, resulting in unnecessary waste. To overcome these shortcomings of the prior art, the present invention provides a lead slag filtering device. Utility Model Content
[0003] The utility model aims to provide a lead slag filtering device, which can filter out lead slag in lead liquid, prevent the lead slag from being brought into the blank strip, and ensure that subsequent production links proceed normally.
[0004] The technical solution adopted by the utility model is that the lead slag filtering device includes a trough-shaped lead liquid channel, semicircular grooves are symmetrically opened on both sides of the upper end of the trough-shaped lead liquid channel, a horizontal axis is arranged in the semicircular groove, and a filtering component is fixedly connected to the horizontal axis; counterweight screws are symmetrically fixedly connected to both ends of the horizontal axis, and a counterweight block is provided at the free end of the counterweight screw.
[0005] The utility model is also characterized in that:
[0006] The width of the filter component is the same as the width of the groove-shaped lead liquid channel; the counterweight screw is arranged outside the groove-shaped lead liquid channel.
[0007] The filter assembly includes a main filter frame, which is V-shaped and has an angle greater than 90 degrees; an auxiliary filter frame is fitted on the outer side of the main filter frame; a first filter and a second filter are respectively arranged between the two side surfaces of the main filter frame and the auxiliary filter frame, and the main filter frame, the auxiliary filter frame and the first filter and the second filter are fixed with bolts; one end of the main filter frame with the first filter is fixed to the horizontal axis.
[0008] Side plates are vertically arranged at both ends of the main filter frame that are in contact with the trough-shaped lead liquid channel.
[0009] The counterweight screw and the first filter screen are arranged on the same side of a vertical line of a plane where the second filter screen is located.
[0010] The beneficial effects of the utility model are:

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0016] The utility model of the lead slag filtering device is as follows Figure 1 and Figure 2 As shown, it includes a trough-shaped lead liquid channel 10, and semicircular grooves 9 are symmetrically opened on both sides of the upper end of the trough-shaped lead liquid channel 10. A horizontal axis 6 is arranged in the semicircular groove 9, and the horizontal axis 6 is circular and adapted to the semicircular groove 9; a filter assembly is fixedly connected to the horizontal axis 6, and the width of the filter assembly is the same as the width of the trough-shaped lead liquid channel 10, ensuring that the lead liquid is completely filtered through the filter assembly; the filter assembly includes a main filter frame 1, and the main filter frame 1 is V-shaped and the angle is greater than 90 degrees; and it is ensured that after the main filter frame 1 is placed in the trough-shaped lead liquid channel 10, after one side is in contact with the ground of the trough-shaped lead liquid channel 10, the height of the other side is consistent with the height of the trough-shaped lead liquid channel 10. A secondary filter frame 2 is fitted onto the outer side of the main filter frame 1. The secondary filter frame 2 is the same shape and size as the main filter frame 1. A first filter 3 and a second filter 4 are respectively positioned between the two side surfaces of the main filter frame 1 and the secondary filter frame 2. The first filter 3 and the second filter 4 are made of metal mesh with a pore size of approximately 5 mm. The main filter frame 1 and the secondary filter frame 2 are fixed to the first filter 3 and the second filter 4 with bolts. One end of the main filter frame 1, where the first filter 3 is provided, is fixed to the horizontal axis 6. Side panels 5 are perpendicularly mounted on both ends of the main filter frame 1 where they contact the trough-shaped lead liquid channel 10. The side panels 5 are provided to prevent lead residue accumulated on the filter from flowing into the filtered lead liquid when the filter device is removed. The main filter frame 1, the secondary filter frame 2, the first filter 3, the second filter 4, and the side panels 5 are all made of a metal material with a melting point greater than that of lead, typically steel.
[0017] The two ends of the horizontal axis 6 are symmetrically fixed with counterweight screws 7, and the free ends of the counterweight screws 7 are provided with counterweight blocks 8. The counterweight screws 7 are arranged outside the trough-type lead liquid channel 10 and are symmetrically arranged relative to the trough-type lead liquid channel 10. The counterweight screws 7 and the first filter screen 3 are arranged on the same side of the vertical line of the plane where the second filter screen 4 is located. Since the main filter screen frame 1, the auxiliary filter screen frame 2, the first filter screen 3, the second filter screen 4 and the side plate 5 are generally made of steel, and the density of steel is less than the density of the lead liquid, the filter device needs to sink into the lead liquid, and the counterweight screws 7 and the counterweight blocks 8 need to provide gravity. In order to ensure that the second filter screen 4 is always close to the bottom surface of the trough-type lead liquid channel 10, it is necessary to ensure that the counterweight screw 7 and the first filter screen 3 are arranged on the same side of the vertical line of the plane where the second filter screen 4 is located.
[0018] The lead slag filtering device of the present invention is inserted into the channel through which the lead liquid flows, so that the horizontal axis 6 at the upper end of the first filter screen 3 falls on the semicircular groove 9 on the outer wall of the groove-shaped lead liquid channel 10. At this time, when the lead liquid flows through the first filter screen 3, the lead slag in the lead liquid will be blocked, and the lead slag with lower density will float on the surface of the lead liquid, while the lead slag with higher density will sink to the bottom of the lead liquid and fall onto the upper part of the second filter screen 4 below, thereby filtering the lead slag. When it is necessary to clean the lead slag, the lead slag filtering device only needs to be slowly and vertically removed, and the lead slag blocked by the filter screens will be adsorbed on the first filter screen 3 and the second filter screen 4 and taken out together for cleaning.
[0019] During use, the first filter screen 3 tilts in the direction of the lead liquid flow, and the second filter screen 4 sinks into the lead liquid through the downward pressure provided by the counterweight block 8 and the counterweight screw 7 and clings to the bottom surface of the groove-shaped lead liquid channel 10. The first filter screen 3 can filter the lead residue contained in the lead liquid flowing through, and the second filter screen 4 is used to collect the lead residue that sinks to the bottom of the lead liquid channel after being filtered by the first filter screen 3, and can take out all the lead residue together when the filter device is vertically removed. The side plate 5 is to prevent the lead residue accumulated on the filter screen from flowing into the filtered lead liquid when the filter device is removed. The utility model can be used by directly placing it into the lead liquid channel, maintaining balance through the counterweight, and does not require rigid connections such as bolts and clips, making it easy to assemble and disassemble and maintain.
