Description

Technical Field

[0001] This invention relates to the technical field of overhaul slag treatment, and in particular to an integrated collection device for the harmless treatment of overhaul slag. Background Technology

[0002] Overhaul slag is the residue from the electrolytic aluminum production process. It comes into direct contact with the cathode material of the electrolytic cell, which is exposed to corrosive electrolytes and molten aluminum at temperatures exceeding 950 degrees Celsius. After a period of operation, the aluminum electrolytic cell requires major overhaul as the electrolytes and molten aluminum continuously corrode it. Overhaul slag mainly consists of cathode carbon blocks, refractory bricks, insulating bricks, and insulation boards. This waste is listed as HW48 hazardous waste in the National Hazardous Waste List. Currently, although wet and pyrometallurgical processes exist for treating overhaul slag, the disposal costs are prohibitively high, far exceeding the willingness of enterprises to bear them, leading to the widespread adoption of low-cost stockpiling methods.

[0003] In existing overhaul slag treatment processes, such as Chinese Patent Publication No. CN121649222A, a resource-based treatment device suitable for overhaul slag is disclosed, which includes a workbench, a support column is provided on the top right side of the workbench, a bracket is provided between the top left side of the workbench and the support column, a conveyor belt is provided on the top of the bracket, a preliminary crushing component is provided on the top right side of the bracket, and a feed hopper is provided on the upper part of the preliminary crushing component.

[0004] In the aforementioned existing technologies, graded crushing is mainly achieved through the integrated design of a preliminary crushing component and a ball mill component. With the help of a circular screen and a vibrator, qualified powder is quickly separated. However, the aforementioned existing technologies do not take into account that the high-risk pollutants in the overhaul slag are mainly concentrated in the surface crystalline layer. If the base bricks and waste slag are crushed together, it will cause low-risk brick chips to mix with high-risk waste slag, resulting in a surge in the amount of hazardous waste. This not only loses the recycling value of the bricks, but also greatly increases the cost and resource consumption of subsequent hazardous waste disposal.

[0005] Therefore, there is still room for improvement in the aforementioned existing technologies. Summary of the Invention

[0006] In order to target and collect the high-risk crystalline layer on the surface of overhaul slag, and avoid damage to the base bricks to ensure its original recycling, this application provides an integrated collection device for the harmless treatment of overhaul slag.

[0007] The integrated collection and treatment equipment for the harmless treatment of overhaul slag provided in this application adopts the following technical solution: An integrated collection device for the harmless treatment of overhaul slag includes an outer shell with an inlet and an outlet; a feeding module located on the outside of the outer shell, corresponding to the inlet; a support module located inside the outer shell for flexibly supporting the bricks; a pressing module located inside the outer shell, above the support module, with the pressing module and support module linked together via a linkage module; a cleaning module located at the bottom of the pressing module for cutting and breaking up surface crystals on the bricks; a pneumatic module located inside the outer shell, connected to the cleaning module; and a separating module located at the inlet and outlet, connected to the pneumatic module, which forms an air curtain to prevent slag from flying out.

[0008] Preferably, the feeding module includes a pusher cylinder, which is fixedly mounted on the feed slide, which is installed on the outside of the housing; and a pusher plate, which is mounted on the output end of the pusher cylinder. The pusher plate and the feed slide are in sliding fit, and the pusher plate corresponds to the position of the feed inlet.

[0009] Preferably, the support module includes a support base, which is fixedly installed inside the outer shell; and a support member, which is slidably disposed on the support base. A first spring is connected between the support member and the support base, and the first spring serves to support and reset.

[0010] Preferably, the pressing module includes a pressing drive component, which is disposed on the top inner wall of the housing, and a pressing plate is installed on the output end of the pressing drive component. The pressing plate has a hollow structure.

[0011] Preferably, the linkage module includes a first linkage member slidably disposed inside the support base, with the first linkage member and the support member having a compression fit; a first snap-fit ​​member mounted on the first linkage member, with a second spring connecting the first snap-fit ​​member and the support base, the second spring providing elastic reset; a second linkage member slidably disposed on the lower pressure plate; a second snap-fit ​​member mounted on the second linkage member, with a third spring connecting the second snap-fit ​​member and the lower pressure plate, the third spring providing elastic reset; the second snap-fit ​​member and the first snap-fit ​​member are arranged facing each other and can snap into each other; initially, the second snap-fit ​​member and the first snap-fit ​​member are offset in the height direction, and when they gradually approach and converge until they overlap in the height direction, they snap into each other in the horizontal direction.

[0012] Preferably, the cleaning module includes a connecting pipe frame, which is slidably disposed inside the lower pressure plate. A limiting block that engages with the second linkage component is installed on the top of the connecting pipe frame. In the initial state, the second linkage component and the limiting block limit the connecting pipe frame in the vertical direction. A slitting component is installed at the lower end of the connecting pipe frame. The hollow slitting component is connected to the connecting pipe frame. The lower end of the slitting component protrudes from the lower surface of the lower pressure plate. Inclined air holes are evenly distributed on the side of the slitting component. The slitting component is arranged radially to divide the crystals into different areas for cutting. An internal groove plate is installed inside the lower pressure plate. The internal groove plate and the inner bottom surface of the lower pressure plate form a hidden groove. The side wall of the hidden groove has a docking hole, which corresponds to the position of the air hole. A rigid plate is slidably disposed in the hidden groove. A fourth spring connects the rigid plate and the hidden groove. The fourth spring provides elastic reset. An elastic plate is installed on the rigid plate. A crushing rod is disposed on the elastic plate. The bottom surface of the hidden groove has a clearance groove corresponding to the position of the crushing rod.

[0013] Preferably, the pneumatic module includes an air pump, which is disposed inside the outer casing.

[0014] Preferably, the separation module includes an air nozzle, which is located at the outlet end of the hidden pipe. A return groove corresponding to the location of the hidden pipe is provided on the outer casing. The return groove serves as a guide, guiding the gas ejected from the air nozzle back into the interior of the outer casing.

[0015] In summary, the beneficial technical effects of this application are as follows: 1. Targeted separation, hazardous waste reduction and resource recycling: Unlike the existing full-volume crushing method, this application achieves targeted stripping and centralized collection of high-risk crystals on the surface of overhaul slag, so that the base bricks are recycled in their original state, which greatly reduces the amount of hazardous waste and disposal costs from the source.

[0016] 2. Hardness sensing and adaptive mode switching: Utilizing the hardness difference between crystals and bricks, when the cutting piece touches the brick surface, the support piece is pressed down and triggered to automatically switch from "cutting" to "crushing" mode, ensuring that the peeling action is more targeted.

[0017] 3. Intensive Compression and Flexible Avoidance: To address the issue of rough and uneven brick surfaces, multiple crushing rods are used for intensive compression, effectively removing residual crystals from the pits. At the same time, to address the differences in the pressing stroke of each crushing rod caused by the uneven surface, an elastic plate adaptively absorbs excess extrusion pressure, allowing the crushing rods to flexibly resist the undulations of the brick surface. This ensures thorough crystal removal while avoiding rigid overpressure that could cause the brick to break, thus guaranteeing the integrity of the recycled bricks. Attached Figure Description

[0020] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0021] This application discloses an integrated collection device for the harmless treatment of overhaul slag. By sensing the difference in hardness between crystals and bricks, the device adaptively switches working modes. Combined with the linkage of pneumatic blowing and mechanical crushing, it efficiently removes high-risk crystals from the surface of bricks, realizing the centralized collection of hazardous waste and the recycling of bricks, and significantly reducing the overall treatment cost.

[0022] Reference Figure 1 , Figure 2As shown, an integrated collection device for the harmless treatment of overhaul slag includes an outer shell 1 with an inlet 11 and an outlet 12; a feeding module 2 located on the outside of the outer shell 1, corresponding to the inlet 11; a supporting module 3 located inside the outer shell 1 for flexibly supporting the bricks; a pressing module 4 located inside the outer shell 1, above the supporting module 3, with the pressing module 4 and the supporting module 3 linked by a linkage module 5; a cleaning module 6 located at the bottom of the pressing module 4 for cutting and breaking up surface crystals on the bricks; a pneumatic module 7 located inside the outer shell 1, connected to the cleaning module 6; and a separating module 8 located at the inlet 11 and outlet 12, connected to the pneumatic module 7, which forms an air curtain to prevent slag from flying out.

[0023] In actual operation, the feeding module 2 feeds the bricks into the inlet 11 and into the support module 3. Then, the pressing module 4 moves down, and the cleaning module 6 contacts the crystalline surface of the brick and cuts and crushes it into pieces. At the same time, the pneumatic module 7 blows the chopped crystals away from the surface of the brick. As the pressing module 4 continues to press down, the thickness of the crystalline layer is cut through. The cleaning module 6 contacts the surface of the brick, and the brick is squeezed down, thereby triggering the internal structure of the support module 3 to descend. Through the linkage of the linkage module 5, the cleaning module 6 switches from the cutting state to the full crushing state, and performs multi-point intensive crushing of the crystals remaining on the surface of the brick. Then, the pressing module 4 resets, and the feeding module 2 pushes the brick out from the outlet 12. Throughout the entire operation, the separating module 8 always forms an air curtain at the inlet 11 and the outlet 12 to block impurities from flying out. This application separates the crystalline layer on the surface of the brick, collects high-risk crystalline waste for abnormal treatment, reduces the processing cost, and makes the bricks recyclable.

[0024] Reference Figure 2 As shown, in order to feed bricks, this application provides a feeding module 2, which includes a pushing cylinder 21, which is fixedly mounted on the feeding slide 22, which is installed on the outside of the outer shell 1; and a pushing plate 23, which is installed on the output end of the pushing cylinder 21. The pushing plate 23 and the feeding slide 22 are in sliding fit, and the pushing plate 23 corresponds to the position of the feeding port 11.

[0025] In actual operation, the pusher cylinder 21 pushes the pusher plate 23 to move along the feed slide 22, thereby pushing the bricks to move.

[0026] Reference Figure 5As shown, the support module 3 includes a support base 31, which is fixedly installed inside the outer shell 1; and a support member 32, which is slidably disposed on the support base 31. A first spring 33 is connected between the support member 32 and the support base 31, and the first spring 33 plays the role of support and reset.

[0027] In actual operation, the support member 32 supports the brick, and the first spring 33 elastically supports and fixes the relative position between the support member 32 and the support base 31. When the removal module 6 breaks the crystals on the surface of the brick, the extrusion and cutting force of the removal module 6 is relatively small due to the low hardness of the crystals, and cannot overcome the elastic force of the first spring 33. Therefore, the distance between the support member 32 and the support base 31 remains unchanged. When the thickness of the crystal layer is cut through, and the removal module 6 comes into contact with the brick surface, the extrusion and cutting force of the removal module 6 gradually increases due to the high hardness of the brick surface, until it overcomes the elastic force of the first spring 33 and pushes the support member 32 downward. The movement of the support member 32 is used to determine whether the crystal layer has been cut through.

[0028] Reference Figure 5 As shown, the pressing module 4 includes a pressing drive 41, which is disposed on the top inner wall of the outer shell 1. A pressing plate 42 is installed on the output end of the pressing drive 41, and the pressing plate 42 has a hollow structure.

[0029] In actual operation, the downward driving component 41 drives the downward pressure plate 42 to descend, thereby causing the cleaning module 6 to contact the surface of the brick to remove the crystals.

[0030] Reference Figure 5 As shown, this application includes a linkage module 5 that coordinates the support module 3 and the removal module 6. The linkage module 5 includes a first linkage member 51, which is slidably disposed inside the support base 31, and the first linkage member 51 and the support member 32 are in a compression fit; a first latching member 52, which is mounted on the first linkage member 51, and a second spring is connected between the first latching member 52 and the support base 31, the second spring serving as an elastic reset function; a second linkage member 53, which is slidably disposed on the lower pressure plate 42; and a second latching member 54, which is mounted on the second linkage member 53, and a third spring is connected between the second latching member 54 and the lower pressure plate 42, the third spring serving as an elastic reset function. The second latching member 54 and the first latching member 52 are arranged facing each other and can latch onto each other. In the initial state, the second latching member 54 and the first latching member 52 are offset in the height direction. When they gradually approach and converge until they overlap in the height direction, they latch onto each other in the horizontal direction.

[0031] In actual operation, when the lower pressure plate 42 descends, it squeezes the first linkage 51 to move outward. The outward movement of the first linkage 51 pushes the second locking member 54 to move outward. The second linkage 53 follows the second locking member 54 to move outward, and the moving second linkage 53 triggers the clearing module 6.

[0032] Reference Figures 3-7 As shown, in order to remove the crystallization on the surface of the bricks, this application provides a cleaning module 6. The cleaning module 6 includes a connecting pipe frame 61, which is slidably disposed inside the lower pressure plate 42. A limiting block 62 that is pressed and engaged with the second linkage 53 is installed on the top of the connecting pipe frame 61. In the initial state, the second linkage 53 and the limiting block 62 limit the connecting pipe frame 61 in the vertical direction. A cutting piece 63 is installed at the lower end of the connecting pipe frame 61. The hollow cutting piece 63 is connected to the connecting pipe frame 61. The lower end of the cutting piece 63 protrudes from the lower surface of the lower pressure plate 42. Inclined air holes 631 are evenly opened on the side of the cutting piece 63. The cutting piece 63 as a whole... The arrangement is radial, thus dividing the crystals into different areas for cutting; an internal groove plate 64 is installed inside the lower pressure plate 42, and the internal groove plate 64 and the inner bottom surface of the lower pressure plate 42 form a hidden groove 65. The side wall of the hidden groove 65 has a docking hole 651, which corresponds to the position of the air blowing hole 631; a rigid plate 66 is slidably disposed in the hidden groove 65, and a fourth spring is connected between the rigid plate 66 and the hidden groove 65, which plays an elastic restoring role; an elastic plate 67 is installed on the rigid plate 66; a crushing rod 68 is disposed on the elastic plate 67, and the bottom surface of the hidden groove 65 has a clearance groove corresponding to the position of the crushing rod 68.

[0033] In actual operation, the lower pressure plate 42 moves downward, and the cutting piece 63 contacts and squeezes the crystals on the surface of the brick. The pneumatic module 7 inputs gas into the connecting pipe rack 61, and the gas is blown out from the air blowing hole 631, blowing the shredded crystals along the upper surface of the brick and blowing them off. When the cutting piece 63 cuts through the crystal layer and contacts the surface of the brick, the cutting piece 63 cannot cut the brick, but the lower pressure plate 42 continues to move downward. Therefore, the pressure of the cutting piece 63 on the brick gradually increases until it overcomes the elastic force of the first spring 33, squeezing the support piece 32 downward. When the lower pressure plate 42 descends, it squeezes the first linkage piece 51 to move it outward. The outward movement of the first linkage piece 51 pushes the second locking piece 54 to move outward. The second linkage piece 53 follows the second locking piece 54 to move outward, thereby causing the second linkage piece 53 to separate from the limiting block 62. As the connecting pipe rack 61 unlocks in the vertical direction, the cutting piece 63 is squeezed upward and retracts into the interior of the lower pressure plate 42 as the lower pressure plate 42 moves downward. The retracted lower pressure plate 42 connects the air blowing hole 631 with the docking hole 651, and the gas enters the hidden groove 65 from the air blowing hole 631 and the docking hole 651. The pressure in the hidden groove 65 increases, and the rigid plate 66 descends under the pressure. The elastic plate 67 and the breaking rod 68 follow the rigid plate 66 down. The breaking rod 68 extends out of the bottom surface of the lower pressure plate 42 and squeezes and crushes the brick surface. Because the brick surface is relatively rough and it is uncertain whether there is still a crystalline layer remaining, the distance that the breaking rod 68 can extend is uncertain. When the breaking rod 68 continues to squeeze after it is pressed against the brick surface, the elastic plate 67 is squeezed and deformed to absorb the excessive squeezing force and prevent the brick from being crushed.

[0034] Reference Figure 2 As shown, the pneumatic module 7 includes an air pump 71, which is installed inside the outer casing 1. The air pump 71 is connected to the connecting pipe frame 61 through an air pipe 72. An air pipe 73 connects the air pump 71 to a hidden pipe 13 opened on the side wall of the outer casing 1. The outlet of the hidden pipe 13 is connected to the partition module 8.

[0035] In actual operation, the air pump 71 pumps out gas, which is then pumped into the connecting pipe rack 61 through the first air pipe 72, and then pumped into the hidden pipe 13 through the second air pipe 73.

[0036] Reference Figure 8 As shown, the separation module 8 includes an air nozzle 81, which is located at the outlet end of the hidden pipe 13. A return groove 14 corresponding to the position of the hidden pipe 13 is provided on the outer shell 1. The return groove 14 plays a guiding role, guiding the gas ejected from the air nozzle 81 back into the interior of the outer shell 1.

[0037] In actual operation, the air pump 71 pumps gas into the hidden pipe 13 through the air pipe 2 73. The gas is sprayed out from the air nozzle 81 to form an air curtain, and then guided back into the interior of the outer shell 1 through the return groove 14.

[0038] The implementation principle of this embodiment is as follows: Step 1: Feeding and blocking: The feeding module 2 pushes the bricks in, and the separating module 8 forms an air curtain to block the debris; Step 2: Slitting and blowing away: The lower pressure plate 42 moves down, the slitting piece 63 cuts the crystals, and the air blowing hole 631 blows away the debris; Step 3: Bottom-touch linkage: When the cutting component 63 touches the brick, the supporting component 32 moves down, triggering the linkage module 5. The second linkage component 53 disengages from the limiting block 62 and unlocks the connecting pipe rack 61. Step 4: Switching to crushing: The connecting pipe rack 61 moves upward and retracts, the air blowing hole 631 connects with the docking hole 651 to guide air into the hidden groove 65, the air pressure pushes the hard plate 66 downward, so that the crushing rod 68 extends to crush the residual crystals densely, and the elastic plate 67 deforms to absorb energy and prevent the bricks from breaking. Step 5: Reset and discharge: The pressing module 4 is reset, and the brick is pushed out.

[0039] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
