Description

Technical Field

[0001] The present invention relates to the technical field of industrial hazardous waste treatment, and particularly to an industrial hazardous waste sintering and purification device. Background Art

[0002] Industrial hazardous waste refers to waste generated during industrial production processes that has dangerous characteristics such as toxicity, corrosiveness, flammability, reactivity, or infectivity. If these wastes are not properly treated, they may cause serious harm to the environment and human health.

[0003] Sintering and purifying industrial hazardous waste is an efficient treatment method. Through high-temperature sintering, harmful substances in the hazardous waste are stabilized, rendered harmless, and resource utilization is achieved. Most of the current sintering and purification devices on the market cannot avoid the problem of uneven heat distribution during the transmission process, and cannot ensure uniform heat distribution at each contact point of the waste products, resulting in local overheating or insufficient heating. For this reason, an industrial hazardous waste sintering and purification device is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the prior art, and to propose an industrial hazardous waste sintering and purification device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: An industrial hazardous waste sintering and purification device includes a sintering unit, a processing unit, and a barrier top cover. The processing unit is interposed in the inner cavity of the sintering unit, and the barrier top cover is installed at the top of the sintering unit. The barrier top cover can isolate the overall device from the high-temperature area and the external environment, reduce heat loss, and improve energy utilization efficiency. The processing unit includes a positioning mechanism arranged in the inner cavity of the sintering unit. The heating mechanism is cross-interposed on the upper end surface of the arranged positioning mechanism. The bottom of the heating mechanism is connected to the upper end surface of the sintering mechanism, and the lower end surface of the sintering mechanism is provided with a holding mechanism; The positioning mechanism includes a positioning block and a positioning groove opened in the inner cavity of the positioning block. A pressing motor is arranged at the middle position of the lower end surface of the positioning block. The other end of the pressing motor is inserted and connected to the middle position of the pressing block. A stabilizing box is installed at the bottom of the pressing block. A cover plate is opened on the outer end surface of the stabilizing box. The staff opens the cover plate covering the surface of the stabilizing box, places the waste products with reduced volume after sintering treatment into the inner cavity of the stabilizing box, and drives the pressing block downward through the pressing motor, so that the pressing force of the pressing block penetrates through the inner cavity of the stabilizing box and presses downward on the upper end surface of the waste products. The waste products are pressed and stabilized in the inner cavity of the stabilizing box, which not only prevents the waste products from shaking or shifting, but also ensures that the waste products maintain a stable position during subsequent processing, thereby enhancing the overall stability of the waste products.

[0006] Preferably, the heating mechanism includes a material passing pipe and a mounting top piece installed on the upper end surface of the intersecting material passing pipes. The other end of the material passing pipe is inserted through the upper end surface of the heating box. The staff takes out the block-shaped waste from the inner cavity and places it into the inner cavity of the material passing pipe from the outside to the inside. Since a blower is externally connected to the left end of the material passing pipe, the waste can smoothly enter the heating box along the inner cavity of the material passing pipe through the externally connected blower. This design uses the airflow provided by the blower to assist in the transportation of the waste, ensuring that the waste can effectively and continuously pass through each processing link, avoiding production interruptions caused by waste accumulation or blockage. Through this airflow boosting method, the waste can efficiently enter the next link from one link.

[0007] Preferably, the material passing pipe is inserted into the inner cavity of the positioning groove, so that the outer end surface of the material passing pipe fits with the inner cavity wall of the positioning groove. The top of the mounting top piece is connected to the top end of the inner wall of the sintering unit. The heating box includes a second box body and a first heating pipe vertically installed in the inner cavity of the second box body. The bottom of the first heating pipe is inclined downward to provide a second heating pipe. The other end of the second heating pipe is inserted into the inner cavity of the sintering mechanism. The hot blower is connected to the other end of the first heating pipe. Heat treatment is carried out by the hot blower into the inner cavity of the first heating pipe. The waste enters the sintering mechanism for sintering treatment through the zigzag pipe formed between the first heating pipe and the second heating pipe. At this time, the block-shaped waste entering the inner cavity of the sintering box can be processed by a plurality of sintering ring pieces arranged in a surrounding manner; The waste is heated by the hot blower into the inner cavity of the first heating pipe. The heating design ensures that the waste can be fully heated before entering the sintering stage, avoiding inconsistent processing effects caused by uneven temperature or insufficient heating. Through the zigzag pipe formed between the first heating pipe and the second heating pipe, the time and efficiency of the waste heating process can be improved. The zigzag pipe makes the conduction of heat energy more uniform, and the waste can receive heat more fully when passing through the pipe, avoiding the problem of uneven heat that may occur in traditional straight pipes.

[0008] Preferably, the sintering mechanism includes a sintering box and a top cavity opened on the upper end surface of the sintering box. An outlet is provided at the bottom edge of the sintering box. A hot blower is opened at the edge of the top cavity. Three sintering ring pieces are vertically arranged in the inner cavity of the sintering box. Since the width of the formed block-shaped waste before sintering is greater than the inner wall width of the outlet, the unsintered waste will not pass through the inner cavity of the outlet and fall out of the device. However, when the block-shaped waste is sintered, the moisture inside it will evaporate, resulting in a reduction in the volume of the block-shaped waste, so that it can pass through the inner cavity of the outlet; Before the formed block-shaped waste products are sintered, their width is greater than the width of the inner wall of the discharge port. At this stage, the volume of the waste products is large and they cannot pass through the inner cavity of the discharge port smoothly, so they will not fall out of the device. The waste products stay in the device and wait for sintering treatment; During the sintering process of the block-shaped waste products, the moisture inside the waste products will be evaporated, resulting in the shrinkage of the volume of the waste products. Moisture evaporation is an important step in the sintering process. The waste products will lose a certain amount of moisture during the heating process, resulting in volume shrinkage. As the volume of the waste products shrinks during the sintering process, the width of the waste products will become smaller than the width of the inner wall of the discharge port. The waste products after sintering can pass through the inner cavity of the discharge port smoothly and finally fall into the inner cavity of the first box.

[0009] Preferably, the sintering ring member includes a ring body and an inner groove opened in the inner wall groove of the ring body. Heating baffles are arranged in the inner cavity of the inner groove. When the block-shaped waste products enter the inner cavity of the sintering ring member, an external heating motor is connected to the ring body. The ring body arranged in a surrounding manner and the heating baffles arranged in the inner cavity of the inner groove in a surrounding manner perform sintering treatment on the waste products. The waste products will move along a set path, so as to ensure that the waste products can receive heat evenly during the sintering process and be effectively sintered. When the waste products pass through these components arranged in a surrounding manner, they can obtain a uniform heat distribution at each contact point, avoiding the phenomena of local overheating or insufficient heating.

[0010] Preferably, the holding mechanism includes a holding box and forming baffles arranged in the inner cavity of the holding box. The processing unit further includes a diversion mechanism arranged below the positioning mechanism. The bottom of the diversion mechanism is connected in series with the processing mechanism. The side end face of the processing mechanism is connected to the inner grid through a circulation box. The diversion mechanism includes a slide rail and a diversion baffle installed at the bottom position of the slide rail. Both sides of the diversion baffle are connected to the outer end wall of the funnel. The rear end face of the slide rail fits against the inner cavity wall of the sintering unit. The industrial waste products that need to be purified are poured into the funnel from the top of the slide rail. Before entering the funnel, the industrial waste products will be blocked by the upper end face of the funnel. Some filamentous or curved strip-shaped industrial waste products that are easily hung will be hung and remain on the upper end face of the diversion baffle. It is suitable for processing these waste products with special shapes such as fibers and long strip-shaped substances, avoiding the situation that it is difficult to effectively purify them due to irregular shapes, effectively slowing down the entry speed of these complex waste products, enabling them to have more time for processing or decomposition, avoiding poor purification effects caused by the shape problems of the waste products, forming a "temporary stagnation" area for this type of waste products, reducing the risk of waste products being left or not fully purified during the processing, and being easy to clean or maintain, ensuring the effective solution of the waste product residue problem during the long-term stable operation of the equipment.

[0011] Preferably, the processing mechanism includes a third box body and a top cavity opened at the top position of the third box body, the front end surface of the third box body is movably connected to the sealing baffle through a hinge, a through hole is opened at the bottom position of one end surface of the third box body, the inner cavity of the third box body is cross-arranged with processing and separation inclined plates, the through hole, the circulation box and the inner cavity of the forming baffle are connected, and the industrial waste after passing through the funnel and the top cavity falls into the inner cavity of the third box body. At this time, the waste passes through the cross-inclined design of the processing and separation inclined plates, so that the waste can fall along multiple cross-inclined surfaces, effectively controlling the falling path and speed of the waste, avoiding accumulation or blockage of the waste due to rapid or disordered falling during the processing process, and the alternating falling path helps to increase the contact time between the waste and the purification surface, thereby enhancing the waste processing and purification efficiency; because the waste will repeatedly fall on multiple cross-inclined surfaces, the contact time of the waste on each layer is increased, which helps to improve the waste processing efficiency. Especially for larger waste or waste with complex shapes, this multi-faceted alternating dropping method can better break up the waste and promote its contact with the purification medium; At the bottom, the partitioning inclined plate discharges the large amount of residual liquid in the waste into the inner cavity of the third box. The staff can collect the discharged residual liquid by opening the sealing baffle to prevent the liquid from accumulating or flowing poorly in the inner cavity of the device, reducing the accumulation of dirt inside the equipment, and preventing the waste from being incompletely sintered due to high humidity during the subsequent purification process. Waste with too high humidity may affect the heat conduction and material reaction during the sintering process, resulting in unsatisfactory or incomplete sintering results. Since waste with lower humidity can better adapt to the sintering process, this design makes the properties of the waste more stable when it enters the subsequent purification process. This not only optimizes the sintering process, but also avoids uneven heating and incomplete sintering caused by excessive humidity, improving the accuracy and efficiency of waste treatment. The waste discharged from the lowest processing and separation inclined plate slides along the transparent holes through the inner cavity of the circulation box and enters the inner compartment. The waste is separated and processed by multiple groups, and the waste is processed separately and orderly. The waste between each two groups can receive appropriate purification or decomposition treatment separately. The thrust generated during the sliding process of the processing and separation inclined plate is used as the basis to squeeze the waste into a block structure at the interval between each two groups. The formed block structure can effectively reduce the fluidity problem of the waste in the subsequent processing process. Since the waste has been compressed into blocks, the gaps and excess volume are reduced, and the undischarged liquid in the waste is mixed during the process of passing through the diversion mechanism, the processing mechanism, the circulation box and the inner compartment.

[0012] Preferably, the sintering unit includes a first box body and movable hinges on both sides of the edge of the front end surface of the first box body. The first box body is movably connected to the sealing door panel through the movable hinges. Universal wheels are installed at the four corners of the bottom of the first box body. A positioning rod is provided on one side of the universal wheel. The inner cavity of the first box body is divided into three working spaces by internal partitions. The universal wheels improve the flexibility of the overall device, and the positioning rod improves the stability of the overall device in the positioning state.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Pour the industrial waste that needs to be purified into the funnel from the top of the slide rail. Before entering the funnel, the industrial waste will be blocked by the upper end surface of the funnel. Some filamentous or curved strip-shaped industrial waste that is easily hung will hang and remain on the upper end surface of the diversion baffle. It is suitable for processing these special-shaped wastes such as fibers and long strips, avoiding the situation where they are difficult to purify effectively due to their irregular shapes, effectively slowing down the entry speed of these complex wastes, giving them more time to be processed or decomposed, and avoiding poor purification effects caused by waste shape problems. A "temporary stagnation" area is formed for this type of waste, which can reduce the risk of waste being left behind or incompletely purified during the processing process, and is easy to clean or maintain, ensuring the effective solution to the problem of waste residue during long-term stable operation of the equipment.

[0014] 2. After passing through the funnel and the top cavity, the industrial waste falls into the inner cavity of the third box. At this time, the waste passes through the cross-inclined design of the separation inclined plates, so that the waste can fall along multiple cross-inclined surfaces, effectively controlling the falling path and speed of the waste, avoiding accumulation or blockage caused by rapid or disorderly falling of the waste during the processing process, and helping to improve the waste processing efficiency.

[0015] 3. Based on the thrust generated during the sliding process of the partition inclined plate, the waste is squeezed to form a block structure at the interval between each two groups. The formed block structure can effectively reduce the fluidity problem of the waste in the subsequent processing process. Since the waste has been compressed into blocks, the gaps and excess volume are reduced. The staff takes the block-shaped waste out of the inner cavity and places it from the outside to the inside into the inner cavity of the feeding pipe. Because the left end of the feeding pipe is externally connected to a blower, the external blower allows the waste to smoothly enter the heating box along the inner cavity of the feeding pipe, avoiding production interruptions caused by waste accumulation or obstruction. Through this airflow boosting method, the waste can efficiently enter the next link from one link.

[0016] 4. The scrap is heated by a hot air blower in the inner cavity of the first heating tube. This heating design ensures that the scrap is fully heated before entering the sintering stage, avoiding inconsistent treatment results due to uneven temperatures or insufficient heating. The tortuous pipe formed between the first and second heating tubes improves the time and efficiency of the scrap heating process. The tortuous pipe allows for more uniform heat transfer, ensuring that the scrap receives more heat as it passes through the pipe, avoiding the uneven heating issues that can occur with traditional straight pipes.

[0017] 5. The blocky waste enters the inner cavity of the sintering ring, and the external heating motor is connected to the ring body. The ring body and the heating baffles arranged in the inner cavity of the built-in groove are arranged in a surrounding manner to sinter the waste. The waste will move according to the set path, thereby ensuring that the waste can receive heat evenly during the sintering process and sinter effectively. When the waste passes through these surrounding components, it can obtain uniform heat distribution at each contact point, avoiding local overheating or insufficient heating.

[0018] 6. Because the width of the formed block waste before sintering is greater than the width of the inner wall of the discharge port, the unsintered waste will not pass through the inner cavity of the discharge port and fall out of the device. However, when the block waste is sintered, the moisture inside the waste will evaporate, causing the volume of the waste to shrink. Moisture evaporation is an important step in the sintering process. The waste will lose a certain amount of moisture during the heating process, resulting in volume shrinkage. As the volume of the waste shrinks during the sintering process, the width of the waste will become smaller than the width of the inner wall of the discharge port. The waste after sintering can smoothly pass through the inner cavity of the discharge port and eventually fall into the inner cavity of the first box.

[0019] 7. The staff opens the cover covering the surface of the stabilizing box and places the scrap that has been shrunk in size after sintering into the inner cavity of the stabilizing box. The pressing motor drives the pressing block downward so that the extrusion force of the pressing block passes through the inner cavity of the stabilizing box and presses down on the upper end surface of the scrap. The scrap is pressed and stabilized in the inner cavity of the stabilizing box, which not only prevents the scrap from shaking or deflecting, but also ensures that the scrap maintains a stable position during the subsequent processing process, thereby enhancing the overall stability of the scrap.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Refer to Figures 1 - 10, Example 1, An industrial hazardous waste sintering and purification device, including a sintering unit 1, a processing unit 2, and a barrier top cover 3. The processing unit 2 is inserted into the inner cavity of the sintering unit 1, and the barrier top cover 3 is installed at the top of the sintering unit 1. The barrier top cover 3 can isolate the overall device from the high-temperature area and the external environment, reduce heat dissipation, and improve energy utilization efficiency. The processing unit 2 includes a positioning mechanism 21 arranged in the inner cavity of the sintering unit 1. The heating mechanism 22 is cross-inserted on the upper end surface of the arranged positioning mechanism 21. The bottom of the heating mechanism 22 is connected to the upper end surface of the sintering mechanism 23, and the lower end surface of the sintering mechanism 23 is provided with a containing mechanism 24; The positioning mechanism 21 includes a positioning block 211 and a positioning groove 212 opened in the inner cavity of the positioning block 211. A pressing motor 213 is arranged at the middle position of the lower end surface of the positioning block 211. The other end of the pressing motor 213 is inserted and connected to the middle position of the pressing block 214. A stabilizing box 215 is installed at the bottom of the pressing block 214. A cover plate 216 is opened on the outer end surface of the stabilizing box 215. The staff opens the cover plate 216 covering the surface of the stabilizing box 215, places the waste product with reduced volume after sintering treatment into the inner cavity of the stabilizing box 215, and drives the pressing block 214 downward through the pressing motor 213, so that the extrusion force of the pressing block 214 penetrates through the inner cavity of the stabilizing box 215 and presses downward on the upper end surface of the waste product. The waste product is pressed and stabilized in the inner cavity of the stabilizing box 215, which not only prevents the waste product from shaking or shifting, but also ensures that the waste product maintains a stable position during the subsequent treatment process, thereby enhancing the overall stability of the waste product.

[0024] Example 2, The heating mechanism 22 includes a material passing pipe 221 and a mounting top piece 222 installed on the upper end surface of the cross-set material passing pipe 221. The other end of the material passing pipe 221 is inserted into the upper end surface of the heating box 223. The staff takes out the block-shaped waste product from the inner cavity of 161 and places it into the inner cavity of the material passing pipe 221 from the outside to the inside. Since the left end position of the material passing pipe 221 is externally connected to a blower, the waste product is smoothly introduced into the heating box 223 along the inner cavity of the material passing pipe 221 through the externally connected blower. This design uses the airflow provided by the blower to assist in the transportation of the waste product, ensuring that the waste product can effectively and continuously pass through each processing link, avoiding production interruption caused by waste product accumulation or blockage. Through this airflow boosting method, the waste product can efficiently enter the next link from one link.

[0025] Embodiment 3: The material passing pipe 221 is inserted through the inner cavity of the positioning groove 212, so that the outer end surface of the material passing pipe 221 fits against the inner cavity wall of the positioning groove 212. The top of the installation top piece 222 is connected to the top end of the inner wall of the sintering unit 1. The heating box 223 includes a second box body 2231 and a first heating pipe 2232 vertically installed in the inner cavity of the second box body 2231. At the bottom position of the first heating pipe 2232, a second heating pipe 2233 is inclined downward. The other end of the second heating pipe 2233 is inserted into the inner cavity of the sintering mechanism 23. The hot air blower 234 is connected to the other end of the first heating pipe 2232. Heat treatment is carried out by blowing hot air into the inner cavity of the first heating pipe 2232 through the hot air blower 234. The waste products enter the sintering mechanism 23 through the zigzag pipe formed between the first heating pipe 2232 and the second heating pipe 2233 for sintering treatment. At this time, the block-shaped waste products entering the inner cavity of the sintering box 231 can be processed by a plurality of sintering ring members 235 arranged in a surrounding manner.

[0026] Embodiment 4: The waste products are heat-treated by blowing hot air into the inner cavity of the first heating pipe 2232 through the hot air blower 234. The heating design ensures that the waste products can be fully heated before entering the sintering stage, avoiding inconsistent treatment effects caused by uneven temperature or insufficient heating. Through the zigzag pipe formed between the first heating pipe 2232 and the second heating pipe 2233, the time and efficiency of the waste product heating process can be improved. The zigzag pipe makes the conduction of heat energy more uniform, and the waste products can receive heat more fully when passing through the pipe, avoiding the problem of uneven heat that may occur in traditional straight pipes.

[0027] Embodiment 5: The sintering mechanism 23 includes a sintering box 231 and a top cavity 232 opened on the upper end surface of the sintering box 231. An outlet 233 is provided at the bottom edge position of the sintering box 231. A hot air blower 234 is opened at the edge position of the top cavity 232. Three sintering ring members 235 are vertically arranged in the inner cavity of the sintering box 231. Since the width of the formed block-shaped waste products before sintering treatment is greater than the inner wall width of the outlet 233, the unsintered waste products will not pass through the inner cavity of the outlet 233 and fall out of the device. However, when the block-shaped waste products are sintered, the moisture inside them will evaporate, resulting in a reduction in the volume of the block-shaped waste products, so that they can pass through the inner cavity of the outlet 233. Before the formed block-shaped waste products are sintered, their width is greater than the inner wall width of the outlet 233. At this stage, the volume of the waste products is large and they cannot pass through the inner cavity of the outlet 233 smoothly, so they will not fall out of the device. The waste products stay in the device and wait for sintering treatment; During the sintering process of the bulk waste, the moisture inside the waste will be evaporated, resulting in the shrinkage of the waste volume. Moisture evaporation is an important step in the sintering process. The waste will lose a certain amount of moisture during the heating process, leading to volume shrinkage. As the volume of the waste shrinks during the sintering process, the width of the waste will become smaller than the width of the inner wall of the discharge port 233. The sintered waste can smoothly pass through the inner cavity of the discharge port 233 and finally fall into the inner cavity of the first box body 11.

[0028] Embodiment 6. The sintering ring 235 includes a ring body 2351 and an inner groove 2352 formed in the inner wall groove of the ring body 2351. Heating baffles 2353 are arranged in the inner cavity of the inner groove 2352. When the bulk waste enters the inner cavity of the sintering ring 235, an external heating motor is connected to the ring body 2351. The ring body 2351 arranged in a surrounding manner and the heating baffles 2353 arranged in the inner cavity of the inner groove 2352 perform sintering treatment on the waste. The waste will move along a set path, so as to ensure that the waste can receive heat evenly during the sintering process and be effectively sintered. When the waste passes through these components arranged in a surrounding manner, it can obtain a uniform heat distribution at each contact point, avoiding the phenomena of local overheating or insufficient heating.

[0029] Embodiment 7. The holding mechanism 24 includes a holding box 241 and forming baffles 242 arranged in the inner cavity of the holding box 241. The processing unit 2 further includes a shunting mechanism 25 arranged below the positioning mechanism 21. The bottom of the shunting mechanism 25 is connected in series with the processing mechanism 26. The side end face of the processing mechanism 26 is connected to the inner grid 16 through a circulation box 27. The shunting mechanism 25 includes a slide rail 251 and a shunting baffle 252 installed at the bottom position of the slide rail 251. Both sides of the shunting baffle 252 are connected to the outer end wall of the funnel 253. The rear end face of the slide rail 251 is attached to the inner cavity wall of the sintering unit 1. The industrial waste to be purified is poured into the funnel 253 from the top of the slide rail 251. Before entering the funnel 253, the industrial waste will be blocked by the upper end face of the funnel 253. Some filamentous or curved strip-shaped industrial wastes that are easily hung will be hung and remain on the upper end face of the shunting baffle 252. It is suitable for treating these special-shaped wastes such as fibers and long strip-shaped substances, avoiding the situation that they are difficult to be effectively purified due to irregular shapes, effectively slowing down the entry speed of these complex wastes, enabling them to have more time for treatment or decomposition, avoiding poor purification effects caused by waste shape problems, forming a "temporary stagnation" area for this type of waste, reducing the risk of waste being left or not fully purified during the treatment process, and being easy to clean or maintain, ensuring the effective solution of the waste residue problem during the long-term stable operation of the equipment.

[0030] Embodiment 8. The processing mechanism 26 includes a third box body 261 and a top cavity 262 opened at the top position of the third box body 261. The front end face of the third box body 261 is movably connected to a sealing baffle 263 through a hinge bar. A through hole 264 is opened at the bottom position of one side end face of the third box body 261. Processing partition inclined plates 265 are arranged crosswise and oppositely in the inner cavity of the third box body 261. The through hole 264, the circulation box 27 and the inner cavity of the forming baffle 242 are communicated. Industrial waste after passing through the funnel 253 and the top cavity 262 falls into the inner cavity of the third box body 261. At this time, due to the design of the processing partition inclined plates 265 arranged crosswise and obliquely, the waste can fall along multiple crosswise and inclined surfaces, effectively controlling the falling path and speed of the waste, avoiding the accumulation or blockage caused by the rapid or disorderly falling of the waste during the processing. The alternating falling of the path helps to increase the contact time between the waste and the purification surface, thereby enhancing the processing and purification efficiency of the waste; since the waste will fall repeatedly on multiple crosswise and inclined surfaces, the contact time of the waste on each layer increases, which helps to improve the processing efficiency of the waste. Especially for larger waste or waste with complex shapes, this multi-sided alternating falling method can better break the waste and promote its contact with the purification medium.

[0031] Embodiment 9. A large amount of residual liquid in the waste is discharged into the inner cavity of the third box body 261 by the lowermost processing partition inclined plate 265. The staff can collect the discharged residual liquid by opening the sealing baffle 263, avoiding the accumulation or poor flow of the liquid in the inner cavity of the device, reducing the dirt accumulation inside the equipment, and preventing the situation that the waste will not be sintered completely due to high humidity during the subsequent purification process. Waste with too high humidity may affect the heat conduction and material reaction during the sintering process, resulting in an unsatisfactory or incomplete sintering effect. Since waste with lower humidity can better adapt to the sintering process, this design makes the properties of the waste more stable when it enters the subsequent purification treatment. This not only optimizes the sintering process but also avoids uneven heating and incomplete sintering caused by too high humidity, improving the accuracy and efficiency of waste treatment.

[0032] In Example 10, waste discharged from the lowest processing and partitioning inclined plate 265 slides along the through-holes 264 through the inner cavity of the circulation box 27 and enters the inner compartment 16. The waste is separated and processed by the multiple groups 162, and the waste is processed separately and orderly. The waste between each two groups 162 can each receive appropriate purification or decomposition treatment. Based on the thrust generated when the processing and partitioning inclined plate 265 slides toward 162, the waste is squeezed to form a block structure between each two groups 162. The formed block structure can effectively reduce the fluidity problem of the waste during subsequent processing. Since the waste has been compressed into blocks, the gaps and excess volume are reduced. In addition, the undischarged liquid in the waste is mixed during the process of passing through the diversion mechanism 25, the processing mechanism 26, the circulation box 27 and the inner compartment 16.

[0033] In embodiment 11, the sintering unit 1 includes a first box body 11 and movable hinges 12 opened on both sides of the edge of the front end surface of the first box body 11. The first box body 11 is movably connected to the sealing door panel 13 through the movable hinges 12. Universal wheels 14 are installed at the four corners of the bottom of the first box body 11. A positioning rod 15 is set on one side of the universal wheel 14. The inner cavity of the first box body 11 is divided into three working spaces by an internal partition 16. The universal wheel 14 improves the flexibility of the overall device, and the positioning rod 15 improves the stability of the overall device in the positioning state.

[0034] Working principle: The industrial waste to be purified is poured from the top of the slide rail 251 into the funnel 253. Before entering the funnel 253, the industrial waste will be blocked by the upper end surface of the funnel 253. Some filamentous or curved strips of industrial waste that are easily hung will hang and remain on the upper end surface of the diverter baffle 252. After passing through the funnel 253 and the top cavity 262, the industrial waste falls into the inner cavity of the third box 261. Since the waste repeatedly falls on multiple intersecting inclined surfaces, the contact time of the waste on each layer is increased. The multi-surface alternating falling method can better break up the waste and promote its contact with the purification medium. At the bottom, the partition inclined plate 265 is used to discharge a large amount of residual liquid in the waste into the inner cavity of the third box 261. The staff can collect the residual liquid discharged by opening the sealing baffle 263; Waste is discharged from the lowest processing and separation inclined plate 265, slides along the transparent hole 264 through the inner cavity of the flow box 27, and enters the inner compartment 16. The waste is separated and processed by the multiple groups 162, and the waste is processed separately and orderly. The waste between each two groups 162 can receive appropriate purification or decomposition treatment separately. Based on the thrust generated by the processing and separation inclined plate 265 sliding toward 162, the waste is squeezed into a block structure at the interval between each two groups 162. The undischarged liquid in the waste is mixed during the process of passing through the diversion mechanism 25, the processing mechanism 26, the flow box 27 and the inner compartment 16. The staff takes the block of waste out of the inner cavity of 161 and places it from the outside to the inside into the inner cavity of the feeding tube 221. Because the left end of the feeding tube 221 is externally connected to a blower, the external blower allows the waste to smoothly enter the heating box 223 along the inner cavity of the feeding tube 221. At this time, the hot blower 234 is connected to the other end of the first heating tube 2232, and the inner cavity of the first heating tube 2232 is heated by the hot blower 234, and then enters the sintering mechanism 23 downward through the tortuous pipe formed between the first heating tube 2232 and the second heating tube 2233 for sintering treatment. At this time, the block waste entering the inner cavity of the sintering box 231 can be processed by multiple groups of sintering rings 235 arranged around it.

[0035] The waste is heated by the heat blower 234 in the inner cavity of the first heating tube 2232. The waste passes through the tortuous pipe formed between the first heating tube 2232 and the second heating tube 2233. The tortuous pipe makes the heat transfer more uniform, so the waste can receive heat more fully when passing through the pipe. The bulk waste enters the inner cavity of the sintering ring 235. An external heating motor is connected to the ring body 2351. The ring body 2351 and the heating baffles 2353 arranged in the inner cavity of the built-in groove 2352 surround the waste and sinter it. The waste moves along a set path. When the waste passes through these surrounding components, it can obtain uniform heat distribution at each contact point. Because the width of the formed block waste before sintering is greater than the width of the inner wall of the discharge port 233, the unsintered waste will not pass through the inner cavity of the discharge port 233 and fall out of the device. However, when the block waste is sintered, the moisture inside it will evaporate, causing the volume of the block waste to shrink, so that it can pass through the inner cavity of the discharge port 233. Before the sintering process, the width of the formed block waste is greater than the width of the inner wall of the discharge port 233. At this stage, the volume of the waste is too large to pass through the inner cavity of the discharge port 233 smoothly, and it will not fall out of the device. The waste will stay in the device and wait for sintering.

[0036] During the sintering process of the block-shaped waste products, the moisture inside the waste products will be evaporated. The waste products will lose a certain amount of moisture during the heating process, resulting in volume shrinkage. As the volume of the waste products shrinks during the sintering process, the width of the waste products will become smaller than the width of the inner wall of the discharge port 233. The sintered waste products can smoothly pass through the inner cavity of the discharge port 233 and finally fall into the inner cavity of the first box body 11.

[0037] The staff opens the cover plate 216 covering the surface of the stabilizing box 215, places the waste products with reduced volume after the sintering process into the inner cavity of the stabilizing box 215, and drives the pressing block 214 downward by pressing the motor 213, so that the pressing force of the pressing block 214 penetrates through the inner cavity of the stabilizing box 215 and presses downward on the upper end surface of the waste products. The waste products are pressed and stabilized in the inner cavity of the stabilizing box 215 and wait for subsequent processing.
