Description

Technical Field

[0001] The invention relates to the technical field of resource recycling, in particular to a lead-acid battery shell micro-lead separation device. Background Art

[0002] At present, the batteries used in cars and electric bicycles are mainly lead-acid batteries, which are low-cost and simple to manufacture. They dominate the electric bicycle market. In 2011, the national production of lead-acid batteries reached 240 million kVA. The service life of lead-acid batteries for cars and electric bicycles is one and a half to two years. Although the quality is strictly controlled according to the process flow during production, many batteries will age after half a year, thus shortening their service life. The amount of waste lead-acid batteries for cars and electric bicycles is increasing year by year, and the total amount is huge, which has a great impact on the environment.

[0003] In order to scientifically and standardizedly recycle discarded lead-acid batteries, a special recycling market has been established. The recycling of lead-acid batteries includes the recovery of lead, the recycling and reuse of the shell, and the separation of acid. The shell of lead-acid batteries is mainly PP, so the development of the recycling and reuse technology of PP shells not only provides a guarantee for the long-term development of the electric bicycle lead-acid battery industry, but also requires sustainable development to save raw materials and secondary utilization of resources.

[0004] According to the process for re-separating micro-lead from the shell of lead-acid batteries of scrap automobiles and electric vehicles described in patent number CN104868189A, the shell fragments are sprayed with a configured spray liquid during use. A single spraying cannot effectively separate the lead ions, and a large amount of spray liquid is wasted, increasing the recycling cost. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a lead-acid battery casing micro-lead separation device to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a lead-acid battery shell micro-lead separation device, comprising a frame, a spraying mechanism arranged on the frame, a bearing mechanism arranged above the frame for bearing shell fragments, and a driving mechanism for driving the bearing mechanism, the bearing mechanism comprising five loading assemblies arranged on the surface of the frame, the four loading assemblies on both sides are slidably arranged in a sliding groove in the frame through a sliding block, and the loading assembly at the center is rotatably arranged on the surface of the frame;

[0007] The loading assembly includes a fixed base, the top of which is fixedly connected to a placement frame via an elastic rubber pad, a filter carrier frame for loading shell fragments is placed in the inner cavity of the placement frame, and drainage ports are provided on both sides of the placement frame;

[0008] The driving mechanism includes a rotating shaft driven by a motor at the back of the frame, one end of the rotating shaft passes through and extends to the front of the frame, one end of the rotating shaft is fixedly connected to the fixed base of the loading assembly at the center, one end of the rotating shaft is fixedly connected to a push rod, and the backs of the sliding blocks of the two or four loading assemblies are fixedly connected to guide rods that pass through and extend to the rear of the sliding groove, and the surfaces of the push rods are respectively in contact with the bottoms of the four guide rods;

[0009] Five loading assemblies are arranged one by one on the surface of the frame in an alternating manner. When in use, the shell of the lead-acid battery is crushed and passed through an 80-100 mesh sieve to obtain crushed materials, and then the crushed materials are evenly stacked in the filter carrier frame. The five filter carrier frames with crushed materials stacked are placed in the placement frame through the handle. At this time, the rotating shaft is in a horizontal state, and then the motor drives the rotating shaft to rotate 9 degrees, driving the push rod to rotate right, and the push rod drives the guide rod to move. The guide rod drives the sliding block to move in the sliding groove. The two sliding blocks on the left move upward in the sliding groove, and the two sliding blocks on the right move downward in the sliding groove. The fixed base in the middle rotates to the right, and the right side of the placement frame is limited by the right limit rod. At this time, the elastic rubber pad is deformed, driving the placement frame to tilt to the right, adjusting the inclination angle, and facilitating the flow of the spray liquid. At this time, the cylinder drives the stop rod to extend from the inner groove to limit the left and right four placement frames to make them tilted. While being able to drive the placement frame to move, its angle is limited to keep it in a horizontal state with the other placement frames to prevent the inclination angle from being too large. After the adjustment is completed, the five placement frames All of them are tilted to the right, and are arranged in parallel and staggered up and down, and the height gradually decreases from left to right. At this time, the filter carrier frames inside the five placement frames are sprayed with cleaning liquid through the spray pipe at the same time. The cleaning liquid spray separates the lead contained in the crushed material and is discharged with the cleaning liquid. At this time, the cleaning liquid inside the leftmost placement frame flows into the silicone guide strip along the drain port on the right, and then flows into the next placement frame for repeated cleaning. After spraying for 20 minutes, the cylinder drives the baffle rod to be retracted, and then the rotating shaft rotates 18 degrees counterclockwise to -9 degrees. At this time, the above steps are repeated, and then the five placement frames adjust their positions. The height of the placement frame on the far right is the highest, and it gradually decreases from right to left, and then sprays for another 20 minutes. After the spraying is completed, the rotating shaft is reset, and then the filter carrier frame is removed, and new fragments are replaced for re-spraying. While the internal lead ions can be effectively removed by spraying, the spray liquid is effectively utilized, which greatly increases the flow of the spray liquid. It automatically circulates through gravity until the fragments in the five placement frames are all rinsed, and each placement frame retains an effective spraying effect.

[0010] As a further solution of the present invention: the surface of the frame is provided with inner grooves located above and below the fixed base of the four loading assemblies on both sides, and the inner cavities of the eight inner grooves are slidably connected with baffle rods driven by cylinders. When in use, through the setting of the baffle rod, when the driving mechanism drives the fixed base to move, a limit is formed on one side of the placement frame, so that the five loading assemblies are tilted in sequence to form a horizontal state, which can accelerate the flow efficiency of the spray liquid.

[0011] As a further solution of the present invention: the surface of the frame is fixedly connected with two limit rods located on the left and right below the fixed base of the center loading assembly. When the rotating shaft rotates, the fixed base is driven to rotate. At this time, the side of the placement frame is limited. At this time, the elastic rubber pad is deformed, driving the placement frame to tilt and adjust the inclination angle to facilitate the flow of the spray liquid.

[0012] As a further solution of the present invention: both sides of the placement frame of the multiple loading components are fixedly connected with silicone guide strips. Through the setting of the silicone guide strips, the internal spray liquid can flow smoothly into the next placement frame, and the spray liquid can be reused. In addition, the nature of the silicone guide strips is that they are squeezed and contracted when the placement frame is raised or lowered, and can automatically reset when the squeezing is lost, and will not interfere with the workflow.

[0013] As a further solution of the present invention: the spray mechanism includes a spray pipe fixed above the frame and connected to the spray liquid source, and the spray pipe is located above the multiple loading assemblies.

[0014] As a further solution of the present invention: the spray mechanism also includes a collection box fixed below the frame, and the collection box is located below the multiple loading assemblies.

[0015] As a further solution of the present invention: the rotation axis has two rotation angles, positive 9 degrees and negative 9 degrees.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention can effectively remove internal lead ions by spraying, and at the same time effectively utilize the spray liquid, greatly increasing the flow of the spray liquid, and automatically circulates through gravity until the fragments in the five placement frames are all washed, and each placement frame retains an effective spraying effect.

[0018] 2. The present invention drives the fixed base to rotate when the rotating shaft rotates. At this time, the side of the placement frame is limited. At this time, the elastic rubber pad is deformed, driving the placement frame to tilt and adjust the inclination angle to facilitate the flow of the spray liquid. The position and angle of the placement frame can be quickly adjusted, and the driving effect can be achieved with only a single power source. BRIEF DESCRIPTION OF THE DRAWINGS
