Description

Technical Field

[0001] This invention relates to the field of slag waste recycling technology, specifically to a waste incineration slag sorting device and slag recycling equipment. Background Technology

[0002] In the field of resource utilization of municipal solid waste incineration slag, after water quenching and cooling, the slag forms an ash slurry containing a large amount of water and mixed with light impurities and heavy components (such as metals, glass, and aggregates). Solid-liquid separation and preliminary sorting must be completed first to create conditions for subsequent metal recovery, aggregate preparation, and other processes. Traditional treatment methods mostly use fixed sedimentation tanks for ash slurry settling, but this has obvious limitations: First, the separation efficiency is low, relying on natural gravity sedimentation which takes 4-8 hours, making it difficult to match the industrial demand for 24-hour continuous slag discharge from incinerators, and easily causing ash slurry accumulation; second, maintenance is difficult, as sticky fine slag easily accumulates at the bottom of the tank, requiring manual cleaning after the machine is stopped, which is not only labor-intensive but also prone to clogging pipes due to residual slag, leading to frequent system interruptions.

[0003] To this end, Chinese Patent No. CN120169798B discloses a device and method for the resource utilization of municipal solid waste incineration slag. By setting up a flow sedimentation component, the slurry after adding water can be stored and collected in a sedimentation tank. During the operation of the sedimentation tank, the slurry gradually settles, and the light and heavy ash residues are separated. Compared with the fixed sedimentation tank, sedimentation can be achieved within the operating time. Moreover, it can be turned over and poured out, and flushed with high-pressure water, making it easier to clean the sludge inside and preventing blockage.

[0004] However, existing equipment relies solely on gravity sedimentation, which can only roughly separate light impurities from heavy slag based on density differences. Although the sedimentation tank cleaning method has been optimized, it still requires periodic shutdowns to complete slurry sedimentation and slag dumping. The processing efficiency is limited by the settling period, making it difficult to meet the industrial-scale processing needs of continuous slag discharge from incinerators. Summary of the Invention

[0007] Preferably, each mounting strip has multiple supports evenly arranged on the side away from the filter plate. Each support is equipped with a partition. Supports on two mounting strips are connected by the partition, and the partition is located between two adjacent filter plates. The partition forms a sealed shielding structure to prevent filter residue from leaking from the gap between adjacent filter plates.

[0009] Preferably, the extrusion device includes a base and an extrusion plate; the base is mounted on a frame, and a main shaft is mounted on the base; one end of the extrusion plate near the auxiliary roller is rotatably connected to the main shaft; the frame is provided with a drive device for driving the extrusion plate to reciprocate around the main shaft.

[0010] Preferably, the driving device includes a first mounting base, a rotating wheel, and a rotary drive assembly; the first mounting base is mounted on a frame, and a first rotating shaft is rotatably mounted on the first mounting base; the rotating wheel is fixedly sleeved on the first rotating shaft, and a first eccentric shaft is provided on the rotating wheel, the axis of the first eccentric shaft being parallel to the axis of the first rotating shaft; a straight groove is provided on the extrusion plate, and the first eccentric shaft on the rotating wheel is slidably engaged with the straight groove on the extrusion plate; the rotary drive assembly is used to drive the first rotating shaft to rotate.

[0011] Preferably, the rotary drive assembly is connected to the rotary driver; in the working state, the rotary driver drives the main roller to rotate while simultaneously driving the first shaft to rotate through the rotary drive assembly.

[0012] Preferably, the rotary drive assembly includes a second mounting base, a first drive wheel, a second drive wheel, and a first connecting rod; the second mounting base is mounted on the frame, and a second rotating shaft is rotatably mounted on the second mounting base, with the drive end of the rotary drive drive being connected to the second rotating shaft; the first drive wheel and the second drive wheel are respectively sleeved on the first rotating shaft and the second rotating shaft; a second eccentric shaft and a third eccentric shaft are respectively mounted on the first drive wheel and the second drive wheel; and both ends of the first connecting rod are hinged to the second eccentric shaft and the third eccentric shaft, respectively.

[0013] Preferably, the frame is provided with a guide rail, and a slider is slidably mounted on the guide rail; a second connecting rod and a gas spring are provided on the guide rail; the two ends of the second connecting rod are respectively hinged to the first eccentric shaft and the slider; the piston rod of the gas spring is connected to the slider.

[0014] Preferably, the frame is provided with a flow guide chamber for collecting filtrate, and the flow guide chamber is located below the filter plate.

[0015] A slag recycling device includes a waste incineration slag sorting device.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention achieves simultaneous conveying, filtering, sorting, and dewatering of waste incineration slag through a frame, mounting belt, and extrusion device. This improves slag sorting efficiency, reduces slag moisture content, and lowers the difficulty of subsequent processing, solving the problem of low efficiency caused by separate sorting and dewatering in traditional slag sorting equipment. Throughout the process, the mounting belt continuously conveys the slag, the filter plates and filter cloth achieve filtration, and the extrusion device enhances dewatering. All components work together to ensure simultaneous slag sorting and dewatering, thus improving processing efficiency.

[0018] 2. This invention, through a support and partition installed on the side away from the filter plate, and a sealed shielding structure formed by connecting the supports on both sides via the partition, achieves the function of preventing slag leakage from the gaps between adjacent filter plates. This improves the slag sorting and recovery rate, avoids pollution of the equipment by leaking untreated slag, and solves the problem of slag leakage and incomplete sorting caused by gaps between adjacent filter plates in traditional methods. Since gaps may exist between adjacent filter plates, the partition forms a shield between them. When the slag moves with the filter plates, the partition prevents slag from leaking out through the gaps.

[0019] 3. This invention achieves stable installation and convenient replacement of the filter cloth by connecting both ends of the filter cloth on the filter plate to the adjacent partition with bolts. It also enhances the filter cloth's sealing performance, ensuring stable filtration results, extending the filter cloth's lifespan, and reducing maintenance costs. This solves the problems of traditional filter cloths being easily detached, cumbersome replacement, and easy leakage of slag at the edges during filtration. When the filter cloth is worn and needs replacement, simply unscrew the bolts connecting the filter cloth and the partition, remove the old filter cloth, align the ends of the new filter cloth with the adjacent partition, and re-secure it with bolts. No disassembly of the filter plate or other components is required. This fixing method ensures that the filter cloth does not loosen during slag compression and movement, and makes filter cloth replacement simple and efficient, continuously maintaining good filtration results.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1-6 A waste incinerator slag sorting device includes a frame 1, mounting belts 2, and a pressing device 3. A main roller 11 and a secondary roller 12 are rotatably mounted on the frame 1, and a rotary driver 13 is provided on the frame 1 to drive the main roller 11 to rotate. Two mounting belts 2 are sleeved on the main roller 11 and the secondary roller 12, and the main roller 11 and the secondary roller 12 are connected by the mounting belts 2. Multiple connecting rods 21 are evenly arranged on the mounting belts 2, and two mounting belts 2 are connected by the connecting rods 21. Filter plates 22 are provided on the connecting rods 21, and two adjacent connecting rods 21 form a group. The two ends of the filter plates 22 are respectively hinged to two connecting rods 21 in the same group. Filter cloth 23 covers the filter plates 22. The frame 1 is provided with a pressing device 3 for pressing the slag on the filter plates 22.

[0033] This invention achieves the simultaneous conveying, filtering, sorting, and dewatering of waste incineration slag through a frame 1, mounting belt 2, and extrusion device 3. This improves slag sorting efficiency, reduces slag moisture content, and lowers the difficulty of subsequent processing, solving the problem of low processing efficiency caused by separate sorting and dewatering in traditional slag sorting equipment. Before processing the slag, it needs to be cooled by spraying or soaking, followed by dewatering and sorting. The rotary drive 13 is preferably a servo motor. In use, the rotary driver 13 starts and drives the main roller 11 to rotate. The main roller 11 drives the auxiliary roller 12 to rotate synchronously through the mounting belt 2. The mounting belt 2 rotates with the main roller 11 and the auxiliary roller 12 and transports the slag. The slag to be sorted is placed on the filter plate 22 of the mounting belt 2. Fine particles and moisture in the slag seep downward through the filter cloth 23 on the filter plate 22, realizing the preliminary filtration, sorting and dewatering of the slag. When the filter plate 22 moves with the mounting belt 2 to the bottom of the extrusion device 3, the extrusion device 3 extrudes the slag on the filter plate 22, further squeezing out the residual moisture in the slag. The squeezed-out moisture also seeps through the filter cloth 23. After extrusion, the filter plate 22 continues to move with the mounting belt 2. Since the filter plate 22 is hinged to the connecting rod 21, when the mounting belt 2 runs to the auxiliary roller 12, the filter plate 22 can naturally flip over, dumping the extruded slag into the designated collection area, completing one sorting and dewatering cycle. Throughout the process, the mounting belt 2 continuously conveys, the filter plate 22 and the filter cloth 23 achieve filtration, and the extrusion device 3 enhances dewatering. All components work together to ensure that slag sorting and dewatering are carried out simultaneously, thereby improving processing efficiency.

[0034] Reference Figures 3-6Each mounting strip 2 has multiple supports 24 evenly arranged on the side away from the filter plate 22. Each support 24 is equipped with a partition 25. The supports 24 on two mounting strips 2 are connected by the partition 25, and the partition 25 is located between two adjacent filter plates 22. The partition 25 forms a sealing and shielding structure to prevent filter residue from leaking from the gap between adjacent filter plates 22.

[0035] This invention utilizes a support 24 and a partition 25 on the side of the mounting belt 2 away from the filter plate 22, along with a sealed shielding structure formed by connecting the two supports 24 via the partition 25. This structure effectively prevents slag leakage from the gaps between adjacent filter plates 22, thereby improving slag sorting and recovery rates and preventing untreated slag leakage from contaminating the equipment. It solves the problems of slag leakage and incomplete sorting caused by gaps between adjacent filter plates 22 in traditional systems. In operation, the rotary drive 13 starts and drives the main roller 11, auxiliary roller 12, and mounting belt 2 to rotate. The slag, placed on the filter plate 22, moves with the mounting belt 2. The filter cloth 23 filters fine particles and moisture, and the extrusion device 3 extrudes and dehydrates the slag. Since gaps may exist between adjacent filter plates 22, the partition 25 forms a shield between them. When the slag moves with the filter plate 22, the partition 25 prevents slag from leaking out through the gaps. When the filter plate 22 moves to the tilting position to dump the slag, the partition 25 moves synchronously with the mounting belt 2, without affecting the dumping of the slag. The sealed shielding structure formed by the partition 25 prevents untreated slag from leaking and contaminating the equipment, and also prevents slag from accumulating on the filter plate 22, ensuring smooth conveying. The partition 25, moving with the installation belt 2, comes into contact with the slag on the filter plate 22, pushing the slag forward synchronously with the installation belt 2, preventing slag from accumulating on the filter plate 22 due to friction from the filter cloth 23 or its own accumulation. Throughout the process, the sealed shielding structure effectively prevents slag leakage, ensuring that all slag is filtered and compressed, improving the sorting effect and recovery rate, while reducing the contamination of the equipment by leaked slag.

[0036] Reference Figure 3 and Figure 4 Each filter plate 22 is provided with a filter cloth 23, and the two ends of the filter cloth 23 are respectively connected to two adjacent partition plates 25 by bolts 251.

[0037] This invention connects the filter cloth 23 on the filter plate 22 to the adjacent partition plate 25 with bolts 251 at both ends, achieving stable installation and convenient replacement of the filter cloth 23. At the same time, it enhances the filtration sealing of the filter cloth 23, thereby ensuring stable filtration effect, extending the service life of the filter cloth 23, and reducing maintenance costs. It solves the problems of traditional filter cloth 23 being not securely installed and easy to fall off, cumbersome replacement, and easy leakage of residue at the edges during filtration. In operation, the slag is placed on the filter plate 22, and the partition plate 25 pushes the slag to move and prevents slag leakage through gaps. The filter cloth 23 tightly covers the filter plate 22 under the fixation of the bolts 251. Fine particles and squeezed water in the slag are filtered through the filter cloth 23. Because the edge of the filter cloth 23 is fixed to the partition plate 25 by the bolts 251, the slag is prevented from leaking out from the gap between the edge of the filter cloth 23 and the filter plate 22 during filtration. When the filter cloth 23 is worn and needs to be replaced, the bolts 251 connecting the filter cloth 23 and the partition plate 25 are unscrewed, the old filter cloth 23 is removed, the two ends of the new filter cloth 23 are aligned with the adjacent partition plate 25, and it is fixed again with the bolts 251. There is no need to disassemble the filter plate 22 or other parts. This fixing method not only ensures that the filter cloth 23 does not loosen during the slag compression and movement, but also makes the replacement operation of the filter cloth 23 simple and efficient, and maintains a good filtration effect.

[0038] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 The extrusion device 3 includes a base 31 and an extrusion plate 32. The base 31 is mounted on the frame 1 and a main shaft 311 is mounted on the base 31. The end of the extrusion plate 32 near the auxiliary roller 12 is rotatably connected to the main shaft 311. The frame 1 is equipped with a drive device 4 for driving the extrusion plate 32 to reciprocate around the main shaft 311.

[0039] This invention achieves gradual pressurization and dehydration of slag through a base 31, an extrusion plate 32, a main shaft 311, and a drive device 4. It adapts to the extrusion requirements of different amounts of slag, thereby improving dehydration efficiency, avoiding slag splashing, and ensuring uniform extrusion. It solves the problems of fixed space in traditional extrusion structures, which are prone to insufficient extrusion or component damage due to fluctuations in the amount of slag. When the device is working, the mounting belt 2 drives the filter plate 22 and filter cloth 23 to move. The slag enters from the side closest to the main roller 11. The drive device 4 drives the extrusion plate 32 to rotate downward around the main shaft 311. The extrusion plate 32 gradually approaches the filter plate 22 from the high side to the low side. Utilizing the spatial gradient characteristic of "large inlet and small outlet", the slag is gradually extruded from loose to tight, avoiding instantaneous strong pressure that could cause slag to splash. During the extrusion process, the moisture in the slag is gradually squeezed out and seeps through the filter cloth 23. As the mounting belt 2 continues to move, the extruded slag is discharged from the small space on the right side. After the extrusion is completed, the drive device 4 drives the extrusion plate 32 to rotate upward and reset, leaving space for the slag on the next set of filter plates 22 to enter. This structure is suitable for slag of different thicknesses to enter from a wide inlet when the amount is large, and can also be effectively extruded when the amount is small. It also improves the dewatering effect through progressive extrusion. Combined with the horizontal conveying of the mounting belt 2, the entire extrusion process is stable and efficient.

[0040] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 The drive device 4 includes a first mounting base 41, a rotating wheel 42, and a rotary drive assembly 43. The first mounting base 41 is mounted on the frame 1, and a first rotating shaft 411 is rotatably mounted on the first mounting base 41. The rotating wheel 42 is fixedly sleeved on the first rotating shaft 411, and a first eccentric shaft 421 is provided on the rotating wheel 42. The axis of the first eccentric shaft 421 is parallel to the axis of the first rotating shaft 411. A straight groove 321 is provided on the extrusion plate 32, and the first eccentric shaft 421 on the rotating wheel 42 is slidably engaged with the straight groove 321 on the extrusion plate 32. The rotary drive assembly 43 is used to drive the first rotating shaft 411 to rotate.

[0041] This invention achieves the function of converting the rotational motion of the rotating wheel 42 into the reciprocating rotation of the extrusion plate 32 around the main shaft 311 through the sliding cooperation of the first mounting base 41, the rotating wheel 42, the first eccentric shaft 421 and the straight groove 321, and the rotational drive assembly 43. This results in stable driving, controllable extrusion frequency, and adaptability to the horizontal extrusion requirements of the extrusion plate 32 with "large inlet and small outlet". It solves the problems of easy jamming and discontinuous extrusion action of traditional drive structures, which are difficult to adapt to the progressive extrusion requirements. In operation, the first rotating shaft 411 is driven to rotate synchronously with the rotating wheel 42 by the rotary drive assembly 43. The first eccentric shaft 421 on the rotating wheel 42 moves in a circular motion with the rotating wheel 42. Since the first eccentric shaft 421 is embedded in the straight groove 321 of the extrusion plate 32 and can slide along the straight groove 321, the circular motion is converted into the reciprocating rotational motion of the extrusion plate 32 around the main shaft 311 through the straight groove 321. When the first eccentric shaft 421 rotates to the side close to the main shaft 311, the extrusion plate 32 rotates downward around the main shaft 311 to progressively extrude the slag on the filter plate 22. By controlling the rotational speed of the first rotating shaft 411, the reciprocating frequency of the extrusion plate 32 can be controlled to match the conveying speed of the installation belt 2, ensuring that the slag on each filter plate 22 can be fully extruded. The entire driving process is smooth and provides continuous power for stable dewatering.

[0042] Reference Figure 1 , Figure 2 and Figure 9 The rotary drive assembly 43 is connected to the rotary driver 13 in a transmission manner; in the working state, the rotary driver 13 drives the main roller 11 to rotate while simultaneously driving the first rotating shaft 411 to rotate through the rotary drive assembly 43.

[0043] This invention, through the rotary drive assembly 43 and the supplementary mounting roller 131, pulley and transmission belt structure, not only achieves synchronous driving of the main roller 11 and the first rotating shaft 411 by a single power source, but also can synchronously adjust the transmission speed of the mounting belt 2 and the swing speed of the extrusion plate 32 by adjusting the output speed of the rotary drive 13. This achieves the effect of adapting to different slag processing volumes and avoiding slag accumulation or insufficient extrusion, solving the problem of easy misalignment and frequent manual calibration required by the independent adjustment of transmission and extrusion speeds in traditional devices. When the device is working, the rotary driver 13 is started. On one hand, it directly drives the main roller 11 to rotate. The main roller 11 drives the auxiliary roller 12 to rotate synchronously through the mounting belt 2. The mounting belt 2 transports the filter plate 22 and the slag on the filter plate 22 to the extrusion device 3. On the other hand, the rotary driver 13 drives the first rotating shaft 411 to rotate synchronously through the rotary drive assembly 43. The first rotating shaft 411 drives the rotating wheel 42 to rotate. The eccentric shaft on the rotating wheel 42 slides along the straight groove 321 of the extrusion plate 32, pushing the extrusion plate 32 to reciprocate around the main shaft 311. When the slag is transported to the area below the extrusion plate 32 by the mounting belt 2, the extrusion plate 32 rotates downward to extrude and dewater the slag. The slag transport and extrusion actions are precisely synchronized. After extrusion, the extrusion plate 32 moves upward to reset with the movement of the eccentric shaft, without affecting the subsequent slag transport. The whole process relies on a single power source to achieve dual-action coordination, which simplifies the structure and avoids action misalignment, ensuring continuous and efficient sorting and dewatering.

[0044] Reference Figure 2 , Figures 7-10 The rotary drive assembly 43 includes a second mounting base 431, a first drive wheel 432, a second drive wheel 433, and a first connecting rod 434. The second mounting base 431 is mounted on the frame 1, and a second rotating shaft 4311 is rotatably mounted on the second mounting base 431. The drive end of the rotary driver 13 is connected to the second rotating shaft 4311. The first drive wheel 432 and the second drive wheel 433 are respectively sleeved on the first rotating shaft 411 and the second rotating shaft 4311. A second eccentric shaft and a third eccentric shaft are respectively mounted on the first drive wheel 432 and the second drive wheel 433. The two ends of the first connecting rod 434 are respectively hinged to the second eccentric shaft and the third eccentric shaft.

[0045] This invention enables a single power source to synchronously and stably drive the main roller 11 and the first rotating shaft 411 through multi-stage belt and linkage transmissions. This improves power transmission stability, reduces transmission losses, and ensures precise synchronization of conveying and extrusion actions, solving the problems of slippage and uneven power distribution leading to asynchronous movements in traditional power transmission structures. A mounting roller 131 is sleeved on the drive end of the rotary driver 13, and a first pulley 132 and a third pulley 133 are sleeved on the mounting roller 131. A second pulley 4312 is sleeved on the second rotating shaft 4311, and a fourth pulley 111 is sleeved on the main roller 11. A first transmission belt 435 spans across the first pulley 132 and the second pulley 4312, connecting them. A second transmission belt 134 spans across the third pulley 133 and the fourth pulley 111, connecting them.

[0046] When the device is working, the rotary driver 13 is started, and its driving end drives the mounting roller 131 to rotate. The mounting roller 131 synchronously drives the first pulley 132 and the third pulley 133 to rotate. The third pulley 133 drives the fourth pulley 111 on the main roller 11 to rotate through the second transmission belt 134. The main roller 11 drives the mounting belt 2 to rotate, realizing the conveying of the filter plate 22 and the slag. The first pulley 132 drives the second pulley 4312 on the second rotating shaft 4311 to rotate through the first transmission belt 435. The second rotating shaft 4311 drives the second drive wheel 433 to rotate. The third eccentric shaft of the second drive wheel 433 pulls the second eccentric shaft of the first drive wheel 432 through the first connecting rod 434, so that the first drive wheel 432 drives the first rotating shaft 411 to rotate. The first rotating shaft 411 drives the rotating wheel 42 to rotate. The eccentric shaft on the rotating wheel 42 slides along the straight groove 321 of the extrusion plate 32, pushing the extrusion plate 32 to reciprocate around the main shaft 311.

[0047] Reference Figure 9 and Figure 10 The frame 1 is provided with a guide rail 44, and a slider 441 is slidably mounted on the guide rail 44; a second connecting rod 442 and a gas spring 443 are provided on the guide rail 44; the two ends of the second connecting rod 442 are respectively hinged to the first eccentric shaft 421 and the slider 441; the piston rod of the gas spring 443 is connected to the slider 441.

[0048] This invention utilizes a guide rail 44 on the frame 1, a slidably mounted slider 441, a second connecting rod 442 connecting the first eccentric shaft 421 and the slider 441, and a gas spring 443 connecting the slider 441. These components achieve the functions of buffering the impact of motion driven by the first eccentric shaft 421, stabilizing the reciprocating rotation trajectory of the extrusion plate 32, and preventing rigid collisions between components. This extends the service life of the transmission components, makes the extrusion action smoother, and improves the stability of the dewatering effect. It solves the problems of rigid impacts, rapid component wear, or extrusion action deviation that are easily generated during the movement of traditional extrusion drive mechanisms. The gas spring 443 can adaptively adjust the buffering force according to the movement speed of the slider 441, ensuring smooth movement of the extrusion plate 32 under different processing capacities. Simultaneously, the guide rail 44 restricts the movement trajectory of the slider 441, indirectly ensuring precise transmission between the first eccentric shaft 421 and the second connecting rod 442, preventing misalignment of the extrusion plate 32 due to transmission deviation, and further ensuring stable slag dewatering. The entire structure improves the operational stability and durability of the device through flexible buffering without affecting power transmission efficiency.

[0049] Reference Figure 2 and Figure 3 The frame 1 is equipped with a flow guide chamber 14 for collecting filtrate, which is located below the filter plate 22.

[0050] This invention utilizes a flow guide chamber 14 mounted on the frame 1 to centrally collect the filtrate generated during the slag filtration and compression process. This prevents filtrate from leaking and contaminating equipment components, facilitates subsequent unified treatment or recycling of the filtrate, and maintains a clean operating environment. It solves the problems of traditional devices lacking a dedicated filtrate collection structure, leading to filtrate overflow, equipment corrosion, or environmental pollution. During operation, the slag to be sorted is placed on the filter plate 22. As it moves with the mounting belt 2, natural moisture and fine particles in the slag leak through the filter cloth 23 and fall directly into the flow guide chamber 14 below. When the filter plate 22 moves below the compression device 3, the compression plate 32 squeezes and dehydrates the slag. The resulting large amount of filtrate also passes through the filter cloth 23 and flows along the surface of the filter plate 22 into the flow guide chamber 14. The flow guide chamber 14 guides the collected filtrate to a designated storage container or processing system through a preset tilt angle or flow channel, preventing filtrate accumulation inside the frame 1.

[0051] Reference Figures 1-6 A slag recycling device, including a waste incineration slag sorting device.

[0052] The slag recycling equipment uses a waste incineration slag sorting device as the core processing unit. It can be equipped with a feeding mechanism and subsequent slag recycling components according to actual needs. When the equipment is working, the feeding mechanism transports the waste incineration slag to be recycled to the filter plate 22 on the installation belt of the sorting device. The subsequent process is completed by the sorting device. As the main roller 11 and auxiliary roller 12 rotate, fine impurities and natural moisture in the slag seep through the filter cloth 23 and fall into the lower guide chamber 14. The guide chamber 14 guides the filtrate to the treatment system, achieving initial solid-liquid separation. The filter plate 22 carries the slag to the extrusion device 3, where the extrusion plate 32 reciprocates around the main shaft 311, gradually extruding the slag using the horizontal space with a large inlet and a small outlet to further remove moisture. The extruded filtrate is also collected by the guide chamber 14. The dehydrated slag continues to move with the filter plate 22. When it reaches the curved section of the installation belt 2, the filter plate 22 naturally flips over, dumping the slag with higher dryness and fewer impurities to subsequent recycling components such as a magnetic separator to separate metals and a crushing device to refine the slag, ultimately completing the slag recycling.
