Description

Technical Field

[0001] This utility model belongs to the technical field of slag treatment equipment, specifically relating to a device for treating municipal solid waste incineration slag that facilitates jig troughing and cleaning. Background Technology

[0002] The slag produced after municipal solid waste incineration typically contains recyclable metal resources (such as aluminum and copper), requiring sorting for resource reuse. In this process, jigs are widely used as key equipment. Jigs primarily separate materials based on density differences within a vertically flowing, variable-speed medium (such as water). Specifically, traditional water jigs use a reciprocating pusher within the chamber to drive the water level to rise and fall periodically, separating lighter materials (such as slag) from heavier metals. However, after long-term use, this fixed tank structure accumulates a large amount of adhering material (such as fine metal particles or impurities) on the inner walls and bottom, leading to a decrease in sorting efficiency. Currently, cleaning these accumulations is mostly done manually by workers, a time-consuming and labor-intensive operation that not only affects equipment continuity but also increases labor costs, resulting in low overall cleaning efficiency and failing to meet the needs of large-scale processing.

[0003] To address the cleaning problem of jigs, existing technologies have proposed improvements. For example, Chinese patent document CN218654887U discloses a cleaning structure for a mining screening jig, which includes a jig body, a screen plate inside the jig body, and a cleaning device. This cleaning device consists of a base, support rods, connecting plates, fixing plates, and a rotating drum, and automatically cleans impurities inside the tank by impacting them with high-pressure water. This structure simplifies the cleaning process to some extent and avoids the inconvenience of manual operation. However, this technology is mainly aimed at mining screening scenarios, and its cleaning mechanism focuses on preventing material blockage and maintaining equipment operation. Impurities are directly discharged with wastewater through water pressure, and the cleaned material usually has no recycling value. In the treatment of municipal solid waste incineration slag, the accumulated material stuck in the jig tank is mainly high-value metals (such as aluminum and copper), requiring both efficient cleaning and rapid recovery of these metal resources to avoid resource waste. The aforementioned existing technologies cannot meet these dual requirements. In particular, under water pressure cleaning mode, metal materials may be lost with the wastewater, resulting in a reduced recovery rate. Furthermore, their fixed tank design still makes it difficult to achieve rapid dumping and material collection. Summary of the Invention

[0004] In response to the problems in related technologies, this utility model proposes a device for treating municipal solid waste incinerator slag that facilitates the troughing and cleaning of a jig, thereby solving the technical problems of difficulty in quickly cleaning the fixed trough of the existing jig and the difficulty in recycling the cleaned material.

[0005] The technical solution of this utility model is implemented as follows: A device for treating municipal solid waste incineration slag that facilitates the lifting and cleaning of a jig, comprising a jig body, a movable trough, a V-shaped guide trough, and a truss lifting mechanism. The movable trough is detachably connected to the upper part of the jig body, and the top edge of the movable trough is provided with lifting lugs. The truss lifting mechanism includes a truss beam that spans above the movable trough, and a movable crane is installed on the truss beam.

[0006] The crane hook engages with the lifting lugs of the movable trough to lift the movable trough as a whole and tilt it to pour materials; a V-shaped guide trough is provided on one side of the movable trough, and a material collection port is provided at the bottom of the V-shaped guide trough.

[0007] This invention achieves overall lifting and tilting of the trough by detachably connecting the jig body to the movable trough and installing lifting lugs on the movable trough, in conjunction with a movable crane on the truss beam. This significantly reduces cleaning time and improves efficiency. Furthermore, a V-shaped guide chute is installed on one side of the movable trough to recover the tilted material, solving the problem of difficulty in simultaneously recovering material during jig cleaning.

[0008] As a further improvement to the above solution, the crane is an electric hoist, which is slidably connected to the truss beam via a traveling trolley. The traveling trolley moves horizontally along the truss beam, allowing the electric hoist to cover multiple work positions laterally and quickly align with the lifting lugs of the movable trough, avoiding the time-consuming manual adjustment of the hook position; at the same time, the electric hoist provides a controllable lifting speed to ensure that the movable trough is tilted and tilted smoothly after being lifted, preventing metal materials from scattering due to shaking.

[0009] As a further improvement to the above solution, the truss beam includes two parallel beams, and the traveling trolley drives the electric hoist to move laterally along the extension direction of the parallel beams.

[0010] Two walking components are provided on both sides of the two parallel crossbeams. The two walking components are correspondingly arranged on the parallel longitudinal beams and move longitudinally along the extension direction of the parallel longitudinal beams.

[0011] As a further improvement to the above solution, the walking trolley includes a support frame, and the bottom of the support frame is provided with a first drive wheel and a first driven wheel, and the first drive wheel and the first driven wheel slide back and forth along the extension direction of the parallel crossbeam.

[0012] The traveling component includes a crossbar, and two parallel crossbeams are fixedly connected to the crossbars on both sides to form a frame structure. At least one crossbar has a second drive wheel and a second driven wheel at its bottom, and slides back and forth along the extension direction of the parallel longitudinal beams via the second drive wheel and the second driven wheel. Through the cooperation between the traveling trolley and the traveling component, the crane can quickly move to the designated position in the horizontal or vertical direction, smoothly lift the movable trough at the corresponding position, and realize the material dumping operation.

[0013] As a further improvement to the above solution, the outer wall of the movable tank is provided with several positioning blocks, and the jig body is provided with corresponding positioning slots. The positioning blocks and positioning slots are connected to each other and locked with bolts. When the movable tank is hoisted and lowered, the positioning blocks automatically enter the positioning slots to achieve docking guidance assistance, eliminate manual calibration, and improve the efficiency of the reset operation after tilting.

[0014] As a further improvement to the above solution, the lifting lugs are symmetrically arranged on both sides of the movable trough wall. The lifting lugs are close to the upper edge of the side wall of the movable trough wall and are spaced apart from the upper edge. The symmetrical distribution of the lifting lugs and the distance between them and the upper edge ensure that the lifting force is evenly transmitted, avoiding single-point stress that could cause deformation of the trough wall or cracking of the lugs, and ensuring the structural integrity of the trough wall during repeated lifting operations.

[0015] As a further improvement to the above solution, the device includes a V-shaped guide trough located in the middle, with several jig main bodies arranged side by side on both sides of the V-shaped guide trough; the movable troughs of each jig main body share the same V-shaped guide trough and truss lifting mechanism. Multiple jig main bodies are equipped with a shared V-shaped guide trough and truss lifting mechanism. The crane alternately slides to serve multiple workstations and tilts the jig onto the same V-shaped guide trough, enabling one machine to clean while another continues sorting, effectively improving capacity utilization.

[0016] As a further improvement to the above solution, a movable metal recycling tanker is provided below the material collection port, with the top opening of the tanker connected to the material collection port. The tanker's bottom casters adapt to the narrow spaces of the workshop, facilitating transportation, and directly connect to the V-shaped guide chute, enabling multi-point recycling with a single tanker.

[0017] As a further improvement to the above solution, the inner wall of the movable tank is lined with wear-resistant ceramic plates, which are fixed to the inner side of the tank by countersunk bolts. The ceramic plates have a high Mohs hardness, resisting the continuous erosion of metal particles and quartz sand in the slag, effectively extending their service life compared to traditional steel tanks. Simultaneously, the countersunk bolt fixing ensures a smooth, unprotruding surface of the liner, reducing material adhesion and supporting the replacement of individual liner plates.

[0018] As a further improvement to the above solution, a screen is detachably connected to the bottom of the movable tank. The screen has multiple mesh openings; the screen is pressed and fixed by a pressure plate at the bottom. After the pressure plate is unscrewed, the screen can be removed to thoroughly clean out fine metal particles stuck in the mesh openings, preventing metal loss due to blockage.

[0019] Beneficial effects:

[0020] By detachably connecting the jig body to the movable trough and installing lifting lugs on the movable trough, along with a movable crane on the truss beam, the entire trough can be lifted and tilted, completely replacing the traditional manual shoveling method. The crane directly lifts the movable trough and tilts it for unloading, allowing the accumulated metal material to quickly detach from the trough under gravity, greatly reducing cleaning time. This is particularly suitable for the cleaning needs of continuous sorting scenarios for municipal solid waste incineration slag. Furthermore, a V-shaped guide chute is installed on one side of the movable trough to recover the tilted material. The tilted metal material slides along the V-shaped guide chute into the collection port, solving the problem of difficulty in simultaneously recovering material during the jig cleaning process.

Therefore, they should not be construed as limitations on this utility model.

[0035] Example:

[0036] like Figures 1-6 As shown, a device for treating municipal solid waste incinerator slag that facilitates jig trough lifting and cleaning includes a jig body 1, a movable trough 2, a V-shaped guide trough 3, and a truss lifting mechanism 4. The movable trough 2 is detachably connected to the upper part of the jig body 1, and the top edge of the movable trough 2 is provided with a lifting lug 21. The truss lifting mechanism 4 includes a truss beam 41, which spans above the movable trough 2, and a movable crane 42 is installed on the truss beam 41. The V-shaped guide trough 3 is provided on one side of the movable trough 2, and a material collection port 31 is provided at the bottom of the V-shaped guide trough 3.

[0037] In this embodiment, the V-shaped guide trough 3 is located in the middle, and two jig bodies 1 are arranged side by side on each side of the V-shaped guide trough 3. The movable troughs 2 of each jig body 1 share the same V-shaped guide trough 3 and truss lifting mechanism 4. Multiple jig bodies 1 are provided with a shared V-shaped guide trough 3 and truss lifting mechanism 4. The crane 42 alternately serves multiple workstations by sliding and tilting onto the same V-shaped guide trough 3, so that when one machine is cleaning the trough, another machine continues to sort, effectively improving the capacity utilization rate.

[0038] In this embodiment, the crane 42 is an electric hoist, which is slidably connected to the truss beam 41 via a traveling trolley 43. The traveling trolley 43 moves horizontally along the truss beam 41, allowing the electric hoist to cover multiple work positions laterally and quickly align with the movable trough 2 to lift the hook 21, avoiding the time-consuming manual adjustment of the hook 421 position. The lifting speed of the electric hoist is controlled at 0.5-1m / min to ensure stable lifting. At the same time, the electric hoist provides a controllable lifting speed to ensure that the movable trough 2 tilts and falls smoothly after being lifted, preventing metal materials from scattering due to shaking.

[0039] The truss beam 41 includes two parallel beams 411. A traveling trolley 43 drives an electric hoist to move laterally along the extension direction of the parallel beams 411. Traveling components 44 are provided on both sides of the two parallel beams 411, and the two traveling components 44 are correspondingly mounted on parallel longitudinal beams 45 and move longitudinally along the extension direction of the parallel longitudinal beams 45. The two parallel longitudinal beams 45 are fixed to the ground foundation by columns, and the bottom of the columns is anchored to the ground foundation with anchor bolts to a depth ≥500mm.

[0040] Specifically, the traveling trolley 43 includes a support 431, with a first drive wheel 432 and a first driven wheel 433 at its bottom, which slide back and forth along the extension direction of the parallel crossbeam 411 via the first drive wheel 432 and the first driven wheel 433. The traveling component 44 includes a crossbar 441, with two parallel crossbeams 411 fixedly connected to the crossbars 441 on both sides to form a frame structure. At least one crossbar 441 has a second drive wheel 442 and a second driven wheel 443 at its bottom, which slide back and forth along the extension direction of the parallel longitudinal beam 45 via the second drive wheel 442 and the second driven wheel 443. Specifically, each drive wheel includes a motor and rollers connected to the motor, which slide on the parallel crossbeam 411 or the parallel longitudinal beam 45. Through the cooperation of the traveling trolley 43 and the traveling component 44, the crane 42 can quickly move to a designated position in the horizontal or vertical direction, smoothly lifting the movable trough 2 at the corresponding position, thus realizing the material dumping operation.

[0041] The hook 421 of the crane 42 cooperates with the lifting lugs 21 of the movable trough 2 to lift the movable trough 2 as a whole and tilt and dump materials. Specifically, the lifting lugs 21 are symmetrically arranged on both sides of the movable trough 2. The lifting lugs 21 are square, close to the upper edge of the side wall of the movable trough 2, and have a distance between them and the upper edge. Specifically, four or eight lifting lugs 21 are symmetrically arranged. The symmetrical distribution of the lifting lugs 21 and the distance between them and the upper edge ensures that the lifting force is evenly transmitted, avoiding single-point stress that could cause deformation of the trough or cracking of the lugs, and ensuring the structural integrity of the trough under repeated lifting. In this embodiment, the drum of the electric hoist is connected to four hooks 421 respectively through steel wire ropes. When lifting the movable trough, the four hooks 421 hook onto the lifting lugs, so that the lifting force is evenly transmitted to the movable trough, ensuring the smooth progress of the lifting and dumping operation.

[0042] In this embodiment, a movable metal recycling tanker 5 is provided below the material collection port 31, and the top opening of the tanker is connected to the material collection port 31. The omnidirectional wheels at the bottom of the tanker are adapted to the narrow space of the workshop, facilitating transportation, and directly connecting to the V-shaped guide chute 3 to realize multi-point recycling with a single tanker.

[0043] In this embodiment, the outer wall of the movable trough 2 is provided with a plurality of positioning blocks 22, and the jig body 1 is provided with corresponding positioning slots 11. The positioning blocks 22 and the positioning slots 11 are connected to each other and locked with bolts. Specifically, the lower part of the positioning block 22 is chamfered, and the positioning slot 11 matches it. When the movable trough 2 is hoisted and lowered, the positioning block 22 automatically enters the positioning slot 11, realizing docking guidance assistance, eliminating manual calibration, and improving the efficiency of the reset operation after tilting.

[0044] In this embodiment, the inner wall of the movable tank 2 is lined with a wear-resistant ceramic liner 12, which is fixed to the inner side of the tank by countersunk bolts. The ceramic liner 12 has a high Mohs hardness, resisting the continuous erosion of metal particles and quartz sand in the slag, effectively extending its service life compared to traditional steel tanks. Simultaneously, the countersunk bolt fixing ensures a smooth, unprotruding surface of the liner 12, reducing material adhesion and supporting the replacement of individual liner 12 pieces. Specifically, the ceramic liner 12 has a thickness of 15-20mm and a Mohs hardness ≥9, resisting slag erosion; the countersunk bolts are installed 2mm below the surface of the liner 12, ensuring a smooth surface and reducing material adhesion.

[0045] In this embodiment, a screen 13 is detachably connected to the bottom of the movable trough 2. The screen 13 has multiple mesh openings. The screen 13 is pressed and fixed by a pressure plate 14 at the bottom. After the pressure plate 14 is unscrewed, the screen 13 can be removed to thoroughly clean out fine metal particles stuck in the mesh openings, preventing metal loss due to blockage. Specifically, the pressure plate 14 is tightly fitted to the bottom of the movable trough 2 via a support shaft to press the screen 13.

[0046] In specific applications, the above-described solution of this utility model provides the following:

[0047] First, the slag from the municipal solid waste incineration furnace is continuously fed into the movable tank 2 of four parallel jigs 1. The jig 1 drives the push rods to reciprocate, causing the water flow in the movable tank 2 to rise and fall at varying speeds. Metals (aluminum, copper) and light slag in the slag are separated according to density. Metal particles are deposited on the screen 13 at the bottom of the tank, and light slag is discharged with the overflow. The sorting continues until the metal accumulation at the bottom of the tank reaches a set threshold, usually 50% to 60% of the tank volume.

[0048] Secondly, when a single jig needs cleaning, the worker loosens the bolts on the side wall of the movable trough 2, disconnects the positioning block 22 from the jig body 1, starts the electric hoist on the truss beam 41, and manipulates it to move horizontally to directly above the movable trough 2. The hook 421 descends and hooks the hoisting lug 21.

[0049] Next, the electric hoist lifts the movable trough 2 and moves it above the V-shaped guide trough 3 in the middle; the movable trough 2 is tilted at 30°-45°, and the metal material slides into the guide trough under the action of gravity, and connects with the metal recycling tanker 5 below through the material collection port 31.

[0050] Finally, the empty movable tank 2 is hoisted back to the jig body 1, the positioning block 22 is automatically inserted into the positioning slot 11, and the sorting can be restarted after the bolts are tightened; the crane 42 slides along the track to another jig station, and the hoisting and tilting steps are repeated.

[0051] This embodiment achieves overall lifting and tilting of the trough by detachably connecting the jig body 1 and the movable tank 2, and by installing lifting lugs 21 on the movable tank 2, in conjunction with the movable crane 42 on the truss beam 41. This significantly reduces cleaning time and improves efficiency. Furthermore, a V-shaped guide chute 3 is installed on one side of the movable tank 2 to recover the tilted material, solving the problem of difficulty in simultaneously recovering material during jig cleaning.

[0052] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
