Abstract
Description
Technical Field
[0001] This utility model relates to the field of extraction device technology, and in particular to a device for extracting waste seepage prevention material from aluminum overhaul slag treatment. Background Technology
[0002] In the aluminum electrolysis production process, the waste seepage prevention material in aluminum overhaul slag contains valuable metals such as lithium and aluminum, as well as harmful substances such as fluorides and cyanides. Traditional treatment methods, such as simple landfilling or incineration, not only waste resources such as lithium and aluminum, but also cause harmful substances to seep into the soil and water, leading to environmental pollution problems. Some early extraction devices suffer from unstable material conveying and insufficient mixing, which prevents defluorinating agents, alkalis, and lithium precipitation agents from fully reacting with the waste slag, resulting in low extraction efficiency. At the same time, the filtration effect in the solid-liquid separation stage is poor, making it difficult to effectively intercept precipitates, further affecting the extraction quality. Utility Model Content
[0003] The main purpose of this invention is to provide a device for extracting waste seepage prevention material from aluminum overhaul slag, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A waste seepage prevention material extraction device for aluminum overhaul slag treatment includes a mixing tank. Support legs are provided at the four corners of the lower end of the mixing tank, and a support plate is provided between the four support legs. A sliding groove is provided at the front of the upper center of the support plate, and a filtration extraction device is installed inside the sliding groove. A liquid outlet pipe is provided at the middle of the lower end of the mixing tank. A support frame is provided at the upper end of the mixing tank, and a stirring mechanism is provided at the upper end of the support frame. The lower part of the stirring mechanism penetrates the support frame and the upper wall of the mixing tank and extends into the interior of the mixing tank. An addition port is provided at the front of the upper end of the mixing tank. A conveying pipe is inserted and fixedly installed at the right end of the mixing tank. A first motor is fixedly installed at the right end of the conveying pipe, and a feeding port is provided at the upper right end of the conveying pipe. A spiral conveying blade is fixedly installed at the output end of the first motor via a rotating rod.
[0006] Preferably, the filtration extraction device includes a filter box, a handle is provided at the front end of the filter box, a telescopic tube is provided at the middle of the upper end of the filter box, a connecting seat is provided on the upper part of the outer surface of the telescopic tube and the lower part of the outer surface of the outlet tube, a fixing ear is provided on the left and right parts of the outer surface of the two connecting seats, and a bolt is threaded through the upper end of the two corresponding fixing ears. A drain pipe is fixedly installed at the middle of the lower end of the filter box, and a control valve is provided on the outer surface of both the outlet pipe and the drain pipe. Two layers of filter screens are provided inside the filter box.
[0007] Preferably, the two connecting seats are sealed together by a sealing gasket and a sealing groove.
[0008] By adopting the above technical solution, it is possible to effectively prevent liquid or gas from leaking from the connection between the two connectors.
[0009] Preferably, the two connecting seats are detachably connected together by fixing lugs and bolts.
[0010] By adopting the above technical solution—using fixing ears and bolts for detachable connection—the installation, disassembly, and maintenance of the equipment are facilitated.
[0011] Preferably, the filter box is connected to the interior of the mixing tank via a telescopic pipe and a liquid outlet pipe, and the liquid outlet pipe extends to the bottom of the support plate via a sliding groove.
[0012] By adopting the above technical solution, the use of telescopic tubes makes the connection between the filter box and the mixing box more flexible and facilitates subsequent disassembly.
[0013] Preferably, the stirring mechanism includes a second motor, a rotating rod is fixedly installed at the output end of the second motor, a small gear is provided on the upper part of the outer surface of the rotating rod, a large gear is meshed with the right part of the outer surface of the small gear, a driving rod is fixedly installed through the middle of the upper end of the large gear, four sets of stirring rods are provided on the outer surfaces of both the rotating rod and the driving rod, and bearings are provided on the upper part and lower part of the outer surface of the driving rod and the lower part of the outer surface of the rotating rod.
[0014] By adopting the above technical solution: the second motor drives the small gear to rotate via a rotating rod, and the meshing of the small gear with the large gear causes the driving rod to rotate as well, thus achieving the effect of dual-shaft mixing. This design can increase the mixing range and intensity, allowing materials to be more thoroughly mixed in the mixing tank. The bearing arrangement reduces friction between rotating parts, lowers energy loss, improves the operating efficiency and stability of the mixing mechanism, and extends the service life of the equipment.
[0015] Preferably, the four sets of stirring rods are arranged in an equidistant circular array, with the four sets of stirring rods on the left and right sides arranged in an alternating pattern.
[0016] By adopting the above technical solution, the stirring rods distributed in an equidistant ring array can evenly distribute the stirring force in the mixing tank, avoiding the formation of dead zones in the stirring. The staggered distribution of the left and right stirring rods further enhances the stirring effect, enabling the materials to produce more complex flow and mixing during the stirring process, thereby improving the uniformity of the material mixing.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. The waste seepage prevention material is precisely conveyed to the mixing tank by the spiral conveyor blades, and the materials are fully mixed by the staggered mixing rods in the mixing mechanism, so that the defluorinating agent, alkali and lithium precipitation agent react with the waste residue quickly; combined with the staged filtration of two layers of filter screens, the sediment is effectively intercepted, achieving efficient solid-liquid separation and greatly improving the extraction efficiency.
[0019] 2. The connector adopts a dual design of sealing gasket and sealing groove for sealing and snap-fit, and fixing ear and bolt for detachable connection. This not only ensures zero liquid leakage and a safe and stable extraction process, but also makes it easy to quickly pull out the filter box by the handle when the filter screen is clogged, so as to easily disassemble, clean and replace parts, reducing the difficulty and time cost of equipment maintenance.

A telescopic tube 52 is provided at the middle of the upper end of the filter box 50.

A drain pipe 56 is fixedly installed at the middle of the lower end of the filter box 50. A control valve 57 is provided on the outer surface of the liquid outlet tube 6 and the drain pipe 56. Two layers of filter screens 58 are provided inside the filter box 50. The two connecting seats 53 are sealed together by a sealing gasket and a sealing groove. The two connecting seats 53 are detachably connected together by the fixing ears 54 and the bolts 55. The filter box 50 is connected to the interior of the mixing tank 1 through the telescopic tube 52 and the liquid outlet tube 6. The drain pipe 56 extends to the bottom of the support plate 3 through the sliding groove 4.
[0031] Through the above scheme: the connecting seat 53 on the upper part of the outer surface of the telescopic pipe 52 and the lower part of the outer surface of the outlet pipe 6 is sealed and snapped together by the sealing gasket and the sealing groove to prevent liquid leakage; at the same time, it is detachably connected by the fixing ear 54 and the bolt 55, which is convenient for installation and maintenance.

After the liquid enters the filter box 50, it passes through two layers of filter screens 58 in sequence to remove the sediment. The filter box 50 can be pulled out by the handle 51 for easy disassembly and replacement.
[0032] In this embodiment, the stirring mechanism 8 includes a second motor 81. A rotating rod 82 is fixedly installed at the output end of the second motor 81. A small gear 83 is provided on the upper part of the outer surface of the rotating rod 82. A large gear 84 is meshed with the right side of the outer surface of the small gear 83. A driving rod 85 is fixedly installed through the middle of the upper end of the large gear 84. Four sets of stirring rods 86 are provided on the outer surfaces of both the rotating rod 82 and the driving rod 85. Bearings 87 are provided on the upper and lower parts of the outer surface of the driving rod 85 and the lower part of the outer surface of the rotating rod 82. The four sets of stirring rods 86 are arranged in a equidistant circular array, and the four sets of stirring rods 86 located on the left and right are staggered.
[0033] Through the above scheme: the second motor 81 starts, driving the rotating rod 82 to rotate, and the small gear 83 on the rotating rod 82 rotates accordingly. The small gear 83 drives the large gear 84 that meshes with it to rotate, and the large gear 84 drives the driving rod 85 to rotate, so that the rotating rod 82 and the driving rod 85 rotate simultaneously. The four sets of stirring rods 86 on the outer surface of the rotating rod 82 and the driving rod 85 are distributed in a circular array at equal distances, and the left and right stirring rods 86 are staggered, which can fully stir the material in the mixing box 1 and make the material evenly mixed. The bearings 87 on the upper and lower parts of the outer surface of the driving rod 85 and the lower part of the outer surface of the rotating rod 82 reduce friction during rotation and ensure the stable operation of the stirring mechanism 8.
[0034] It should be noted that this utility model is a waste seepage prevention material extraction device for aluminum overhaul slag treatment. During use, the waste seepage prevention material after aluminum overhaul slag treatment is fed into the inlet 12 of the conveying pipe 10. The first motor 11 is started, and the first motor 11 drives the rotating rod to rotate the spiral conveying blades 13, conveying the waste seepage prevention material into the mixing tank 1, completing the initial conveying and feeding of the waste slag. The second motor 81 is started by the controller, and its output end drives the rotating rod 82 to rotate. The small gear 83 on the outer surface of the rotating rod 82 rotates accordingly. Through gear meshing, the small gear 83 drives the large gear 84 to rotate, and the large gear 84 in turn drives the driving rod 85. The rotation causes the rotating rod 82 and the driving rod 85 to rotate synchronously. The four sets of stirring rods 86, which are distributed in a circular array at equal distances on their outer surfaces and are staggered left and right, fully stir the waste seepage prevention material in the mixing tank 1 to achieve preliminary mixing of the materials. Then, through the addition port 9 at the front of the upper end of the mixing tank 1, the defluorinating agent, alkali and lithium precipitation agent are added in sequence. After the agents are added, the stirring mechanism 8 continues to work to allow the agents to fully mix and react with the waste seepage prevention material, so that the defluorinating, pH adjustment and lithium precipitation reactions can be fully carried out. Finally, the control valve 57 on the liquid outlet pipe 6 is opened, and the liquid after reaction in the mixing tank 1 flows into the filter box 50 through the liquid outlet pipe 6 and the telescopic pipe 52. The connecting seat 53 on the upper part of the outer surface of the telescopic tube 52 and the lower part of the outer surface of the outlet tube 6 are sealed by a sealing gasket and a sealing groove to prevent liquid leakage. At the same time, the fixed ear 54 and bolt 55 enable detachable connection for easy installation and maintenance. After the liquid enters the filter box 50, it passes through two layers of filter screens 58 in sequence to intercept and remove the sediment, achieving solid-liquid separation. Open the control valve 57 on the drain pipe 56, and the filtered liquid is discharged through the drain pipe 56. The drain pipe 56 extends through the sliding groove 4 to the bottom of the support plate 3 for easy collection of the filtered liquid for further processing or extraction of target products. When the filter screen 58 intercepts too much sediment and affects the filtration effect, the filter box 50 can be pulled out from the sliding groove 4 by the handle 51, the bolt 55 on the connecting seat 53 can be removed, and the filter box 50 can be removed for cleaning, replacement of filter screens 58, and other maintenance operations.
