Description

Technical Field

[0001] This invention relates to the field of chemical solid waste treatment technology, specifically to a treatment device for solid waste from chemical production. Background Technology

[0002] In chemical production processes, the interaction between catalysts and chemical raw materials often generates a large amount of solid residue. These solid residues typically have crystalline forms of chemically synthesized compounds adhering to their surfaces. These crystals may contain harmful components, and if disposed of directly without treatment, they can cause potential pollution to the soil and environment during subsequent treatment processes such as landfilling. To ensure the harmless treatment of these wastes, the crystalline chemical compounds adhering to the residue surface must be further treated. A common practice is to use thermal decomposition processes to break down the chemical components in the crystals into harmless substances. This process can significantly reduce the harmful components in solid waste, thus ensuring no chemical pollution to the environment during landfilling. Furthermore, thermal decomposition not only reduces waste treatment costs but also lays the foundation for its subsequent resource utilization.

[0003] Currently, existing chemical solid residue treatment equipment typically lacks the function of effectively crushing pre-treated chemical solid residues during use. Furthermore, when screening the crushed chemical solid residues, incomplete screening may occur. In addition, existing treatment equipment has not yet achieved precise and controllable screening during high-temperature thermal decomposition of chemical solid residues. This may result in some chemically synthesized crystals inside the solid residues not being completely decomposed during the pollution-free treatment process. In addition, the thermal decomposition screen may easily become clogged during this process.

[0004] Based on this, we propose a treatment device for solid waste from chemical production to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a treatment device for solid waste from chemical production, which solves the problems mentioned in the background art, such as the lack of effective crushing function, incomplete screening, difficulty in achieving accurate screening during thermal decomposition, and easy clogging of the screen.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a treatment device for solid waste from chemical production, comprising a pyrolysis chamber, gas treatment mechanisms provided on both sides of the pyrolysis chamber, feeding mechanisms installed on both sides of the top of the pyrolysis chamber, and a mechanical transmission mechanism connected to one side of the top of the pyrolysis chamber.

[0007] The top two sides of the pyrolysis chamber are provided with feeding ports. A first transmission component is provided on the side of the pyrolysis chamber near the feeding port. A second transmission component is installed in the middle of one side of the pyrolysis chamber. Filter holes are also provided on the two sides of the pyrolysis chamber near the second transmission component.

[0008] The interior of the pyrolysis chamber is provided with a decomposition cavity. A V-shaped sieve plate is installed at the top of the inner cavity of the decomposition cavity, and a high-temperature decomposition component is provided at the bottom of the inner cavity of the decomposition cavity. A discharge pipe is also connected to the outer side of the pyrolysis chamber away from the second transmission component.

[0009] The V-shaped sieve plate has a collection slot in the middle, and a flow guide hood is installed at the bottom of the V-shaped sieve plate. The flow guide hood is connected to the discharge pipe. Two sets of guide plates are also provided at both ends of the V-shaped sieve plate.

[0010] The high-temperature decomposition assembly includes a first screening plate frame, with pusher arms connected to the bottom of both sides of the first screening plate frame, a second screening plate frame at the bottom of the first screening plate frame, and oscillating guide seats at both ends of the second screening plate frame and the first screening plate frame. High-temperature decomposition components are also respectively installed inside the second screening plate frame and the first screening plate frame.

[0011] The high-temperature decomposition component includes an electric heating substrate. Both ends of the electric heating substrate are provided with micro motors. The two sets of micro motors are connected by a positive and negative screw. An adjustment baffle is provided inside the electric heating substrate. Both ends of the adjustment baffle are threaded to the positive and negative screws. Multiple sets of material passage holes are opened through the adjustment baffle and the top of the electric heating substrate.

[0012] The gas processing mechanism includes a heat exchange component, one end of which is connected to a negative pressure adsorption component. A pressure storage component is provided between the heat exchange component and the negative pressure adsorption component. A refrigeration box is also provided at the bottom of the heat exchange component.

[0013] The pressure accumulator includes an air storage cylinder. One end of the inner cavity of the air storage cylinder is connected to a first compression spring. A sealing valve plate is installed at one end of the first compression spring. A sealing retaining ring is provided around the inner wall of the air storage cylinder near the sealing valve plate. A sensor switch is installed at both ends of the sealing retaining ring. Contact switches are respectively provided on both sides of the end of the air storage cylinder near the sealing valve plate. Telescopic adjustment grooves are provided on both sides of the air storage cylinder near the sealing retaining rings. A push block is provided inside each of the two sets of telescopic adjustment grooves. A second compression spring is also connected between the push block and the telescopic adjustment groove.

[0014] Based on the above technical features, the chemical solid waste treatment equipment designed in this invention mainly consists of a pyrolysis chamber, a gas treatment mechanism, a feeding mechanism, and a mechanical transmission mechanism. The mechanical transmission mechanism includes a metal cover, a drive motor, a transmission base plate, a drive gear, a first transmission component, and a second transmission component. This mechanical transmission mechanism can transmit power to the first transmission component, the second transmission component, the third transmission component, and the negative pressure adsorption component via a transmission belt and a transmission toothed belt. When the third transmission component is running through the mechanical transmission mechanism, the chemical solid residue to be treated can be fed into the feeding ports opened on both sides of the top of the pyrolysis chamber via a conveyor belt. When the first transmission component is running through the mechanical transmission mechanism, the chemical solid residue to be treated can be crushed by a crushing shaft. The crushed chemical solid residue can be discharged and screened simultaneously through a V-shaped sieve plate installed on the top of the decomposition cavity.

[0015] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the top two sides of the decomposition cavity are provided with limiting grooves, and the inner walls of the two sets of limiting grooves are provided with two sets of guide plate grooves. The guide plate grooves are matched with the guide plate structure, and the guide plate grooves and guide plates are in sliding fit. The bottom two sides of the decomposition cavity are provided with four sets of oscillating guide grooves. The oscillating guide grooves are matched with the oscillating guide seat structure, and the oscillating guide grooves and oscillating guide seats are in sliding fit.

[0016] Based on the above technical features, the limiting groove and guide plate groove at the top of the decomposition cavity, through sliding cooperation with the guide plate, ensure the stable installation and precise positioning of the V-shaped screen plate. This limiting design helps prevent the V-shaped screen plate from shifting or moving during use, ensuring the stability and accuracy of screening. The sliding cooperation between the bottom oscillating guide groove and the oscillating guide seat can transmit vibration to the V-shaped screen plate and other screening components. This design can effectively prevent solid residue from adhering to the screen plate, while improving screening efficiency and avoiding clogging problems.

[0017] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the feeding mechanism includes a metal shell, a conveyor belt is installed inside the metal shell, and a third transmission component is also provided on one side of the conveyor belt and the metal shell.

[0018] Based on the above technical features, the conveyor belt in the feeding mechanism is responsible for conveying the chemical solid residue to be processed to the feeding port at the top of the pyrolysis chamber. The setting of the conveyor belt ensures the continuous and stable conveying of the residue, which helps to improve the processing efficiency and avoid the accumulation or jamming of the residue during the conveying process.

[0019] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the mechanical transmission mechanism includes a metal cover, a drive motor is installed on one side of the outer side of the metal cover, a transmission base plate is connected to one side of the metal cover, two sets of drive gears are rotatably connected to the inner center of the transmission base plate, the two sets of drive gears are meshed together, one end of one set of drive gears, the third transmission component and the negative pressure adsorption component are all equipped with a first transmission component, the first transmission component is connected to the output end of the drive motor, and the two sides of the two sets of drive gears are respectively connected to a second transmission component.

[0020] Based on the above technical features, the drive motor in the mechanical transmission mechanism provides the core power for the operation of the equipment. Through the transmission base plate and drive gear, the power is transmitted from the output end of the drive motor to each transmission component. The first transmission component is connected to the output end of the drive motor. Through the meshing motion of the drive gear, the power is evenly distributed, providing sufficient power support for each part of the equipment.

[0021] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the first transmission component includes a transmission mounting shell, and two sets of transmission gears are rotatably connected inside the transmission mounting shell. The two sets of transmission gears are meshed together, and a crushing shaft is installed at one end of each set of transmission gears. A third transmission component is also provided at one end of one set of transmission gears and the second transmission component.

[0022] Based on the above technical features, the end of the transmission gear is connected to a crushing shaft. Through linkage with the transmission component, the crushing shaft can rotate and crush the chemical solid residue. This crushing process is crucial for the pretreatment of chemical solid residue, effectively reducing the particle size of the residue and improving the efficiency of subsequent screening and thermal decomposition.

[0023] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the second transmission component includes a fixed base plate, and a cam is provided on the side of the fixed base plate away from the third transmission component, and the cam is connected to the third transmission component for transmission.

[0024] Based on the above technical features, this solution uses a cam installed on one side of the fixed substrate. When the cam rotates, it can move the V-shaped sieve plate and the first screening plate frame. When the V-shaped sieve plate moves, it can screen the chemical solid residues flowing through the filter screen, preventing the chemical solid residues from adhering to or clogging the filter screen of the V-shaped sieve plate. Similarly, the first screening plate frame in the moved state can drive the second screening plate frame to shake through the push-top arms installed on both sides of the bottom. The first and second screening plate frames in the shaking state can shake the electric heating substrates installed inside. This can prevent chemical solid residues from adhering to and clogging the material passage holes of the two sets of electric heating substrates, while also improving the efficiency of the thermally decomposed chemical solid residues passing through the material passage holes.

[0025] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the heat exchange component includes a heat exchange cylinder, an air inlet pipe is installed at one end of the heat exchange cylinder, an exhaust pipe is connected to the end of the heat exchange cylinder away from the air inlet pipe, a spiral heat exchange tube is connected between the exhaust pipe and the air inlet pipe, the spiral heat exchange tube is located inside the heat exchange cylinder, and hot water exchange pipes are respectively connected to the outer two sides of the heat exchange cylinder.

[0026] Based on the above technical features, this solution uses a spiral heat exchange tube structure design to create a long-path flow of high-temperature gas inside the tube. This not only extends the contact time between the high-temperature gas and the cooling water, but also improves the heat transfer efficiency. At the same time, the heat exchange tubes on both sides of the heat exchange cylinder allow the cooling water to enter from the outside and carry away the heat.

[0027] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the interior of the refrigeration box is provided with a purification cavity, the interior of the purification cavity is filled with waste gas decomposition liquid, the top of the refrigeration box near the purification cavity is provided with an installation cavity, the installation cavity is provided with two sets of circulating pumps, the two sets of circulating pumps are respectively connected to the middle of the hot water exchange pipe, and an exhaust valve is also provided on the outer side of the refrigeration box, the exhaust valve is connected to the purification cavity.

[0028] Based on the above technical features, this solution sets up a purification cavity inside the refrigeration box and fills it with waste gas decomposition liquid. When the waste gas is discharged through the heat exchange components, the harmful components in the waste gas react chemically with the waste gas decomposition liquid through the purification cavity, thereby effectively decomposing the harmful substances. This design ensures that the emitted gas is purified, greatly reducing its harm to the environment and enhancing the environmental performance of the equipment.

[0029] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the exhaust ports of the exhaust pipe and the hot water exchange pipe are both located at the bottom of the inner cavity of the purification cavity, and the air inlet port of the exhaust valve is located at the top of the inner cavity of the purification cavity.

[0030] Based on the above technical features, the exhaust port of the exhaust pipe is located at the bottom of the purification cavity. This means that the gas discharged from the heat exchange system can fully contact the waste gas decomposition liquid. Since the waste gas usually contains harmful substances, the position of the exhaust pipe ensures that these gases can fully react with the decomposition liquid at the bottom of the purification cavity when they are discharged through the bottom. Through this design, the harmful components in the waste gas can be effectively decomposed to achieve the purpose of purification. The air inlet of the exhaust valve is located at the top of the purification cavity. By utilizing the principle of gas buoyancy, by setting the air inlet at the top, the harmless gas after the reaction can be discharged in time during the purification process, preventing the gas from accumulating inside the cavity and causing excessive pressure.

[0031] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the waste gas decomposition liquid is an oxidant solution, specifically a sodium hypochlorite solution.

[0032] Based on the above technical characteristics, sodium hypochlorite solution, as a commonly used oxidant, can decompose harmful components in waste gas through strong oxidation, especially organic matter, sulfides, or other reducing harmful substances. Using sodium hypochlorite solution for treatment can quickly oxidize pollutants in waste gas and convert them into harmless substances, thereby ensuring the safety of the emitted gas.

[0033] This invention provides a treatment device for solid waste from chemical production, which has the following technical features and beneficial effects:

[0034] 1. This equipment achieves the crushing function of pretreated chemical solid residues through a mechanical transmission mechanism, effectively solving the problem of existing equipment lacking crushing processing. The crushing shaft, in conjunction with the flow guidance and filtration functions of the V-shaped screen plate, can screen the crushed residues, ensuring that the residues reach the ideal particle size before entering the subsequent pyrolysis treatment stage. This not only improves the uniformity of residue processing but also reduces the clogging problem caused by uncrushed large particles. Furthermore, the larger chemical solid residues filtered by the crushing shaft through the V-shaped screen plate can be discharged externally using the discharge pipe. The discharged larger chemical solid residues can be transported to the conveyor belt by other conveying devices and crushed again by the crushing shaft until the chemical solid residues to be processed can smoothly pass through the filter screen of the V-shaped screen plate, providing a stable foundation for the continuous operation of the equipment.

[0035] 2. The V-shaped sieve plate in this solution is responsible for the preliminary screening of crushed chemical solid waste in the equipment. Its design consists of a collection trough, a flow guide hood, and a guide plate, ensuring that smaller waste can pass directly through the filter screen into the high-temperature decomposition component, while larger waste is discharged through the collection trough and the flow guide hood. The flow guide hood is connected to the discharge pipe, allowing larger waste to be discharged quickly and preventing blockage. This screening process not only ensures the smooth progress of high-temperature decomposition but also avoids incomplete decomposition caused by excessively large waste, thus improving the operational stability of the equipment.

[0036] 3. Through the scientific design of the screening plate frame and the electric heating plate, this solution greatly reduces the risk of screen blockage during the thermal decomposition process. The linkage design of the adjusting baffle and the forward and reverse screws allows the electric heating plate to regulate the passage of chemical solid residues at different stages. Driven by a micro motor, the adjusting baffle prevents residues from falling prematurely when needed, while also avoiding excessive untreated particles in the high-temperature decomposition zone. This not only optimizes the thermal decomposition effect of the residues but also effectively prevents blockage problems, ensuring that the equipment can maintain stable operating performance even at high temperatures.

[0037] 4. In this solution, the negative pressure adsorption component operates synchronously through a mechanical transmission mechanism, drawing the toxic gases generated by thermal decomposition into the pressure storage component. Subsequently, the gas is transported to the heat exchange component for cooling through the adjustment of the compression spring. The heat exchange component consists of spiral heat exchange tubes and low-temperature waste gas decomposition liquid, which can effectively reduce the gas temperature and prevent the diffusion of toxic gases in a high-temperature environment. The cooled gas is further neutralized by entering a sodium hypochlorite solution through the exhaust pipe. This design ensures multiple safety and effectiveness of the gas treatment process, avoids pollution of the external environment by the equipment, and improves the efficiency of gas cooling and purification.

[0038] 5. This solution ensures the complete decomposition of chemical solid waste through a dual decomposition structure consisting of a first screening plate, a second screening plate, and an electric heating plate. Under the control of a micro motor, the electric heating plate in the first screening plate performs preliminary decomposition of chemical residues by adjusting the baffle. This dual decomposition process not only solves the problem of incomplete decomposition of chemically synthesized crystals but also prevents clogging of the screening plate and heating plate, further improving the efficiency of high-temperature decomposition and ensuring the safety and thoroughness of the chemical solid waste treatment process.

[0076] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0077] Please see Figures 1 to 15 This invention provides a technical solution for a treatment device for solid waste from chemical production:

[0078] A chemical production solid waste treatment device includes a pyrolysis chamber 1, gas treatment mechanisms 2 are provided on both sides of the pyrolysis chamber 1, and feeding mechanisms 3 are respectively installed on both sides of the top of the pyrolysis chamber 1. The gas treatment mechanism 2 includes a heat exchange component 21, which includes a heat exchange cylinder 211. An air inlet pipe 212 is installed at one end of the heat exchange cylinder 211, and an exhaust pipe 213 is connected to the end of the heat exchange cylinder 211 away from the air inlet pipe 212. A spiral heat exchange tube 214 is connected between the exhaust pipe 213 and the air inlet pipe 212. The spiral heat exchange tube 214 is located inside the heat exchange cylinder 211, and hot water pipes 215 are respectively connected to the outer sides of the heat exchange cylinder 211.

[0079] One end of the heat exchange component 21 is connected to the negative pressure adsorption component 22. A pressure storage component 23 is provided between the heat exchange component 21 and the negative pressure adsorption component 22. The pressure storage component 23 includes an air storage cylinder 231. One end of the inner cavity of the air storage cylinder 231 is connected to a first compression spring 232. A sealing valve plate 233 is installed at one end of the first compression spring 232. A sealing retaining ring 234 is provided around the inner wall of the air storage cylinder 231 near the sealing valve plate 233. A sensor switch 235 is installed at both ends of the sealing retaining ring 234. A contact switch 236 is provided on both sides of the end of the air storage cylinder 231 near the sealing valve plate 233. A telescopic adjustment groove 237 is provided on both sides of the air storage cylinder 231 near the sealing retaining ring 234. A push block 238 is provided inside the two sets of telescopic adjustment grooves 237. A second compression spring 239 is also connected between the push block 238 and the telescopic adjustment groove 237.

[0080] A refrigeration box 24 is located at the bottom of the heat exchange assembly 21. A purification cavity 241 is opened inside the refrigeration box 24, which is filled with waste gas decomposition liquid 242. An installation cavity 243 is opened at the top of the refrigeration box 24 near the purification cavity 241. Two sets of circulating pumps 244 are installed inside the installation cavity 243. The two sets of circulating pumps 244 are respectively connected to the middle of the hot water exchange pipe 215. An exhaust valve 245 is also provided on the outside of the refrigeration box 24. The exhaust valve 245 is connected to the purification cavity 241. The exhaust ports of the exhaust pipe 213 and the hot water exchange pipe 215 are both located at the bottom of the inner cavity of the purification cavity 241. The air inlet port of the exhaust valve 245 is located at the top of the inner cavity of the purification cavity 241. The waste gas decomposition liquid 242 is an oxidant solution, specifically a sodium hypochlorite solution.

[0081] During operation, the gas storage cylinder 231 stores toxic and harmful gases. When the internal gas pressure exceeds the tension of the first compression spring 232, the gas pushes the sealing valve plate 233 open, rapidly releasing it into the heat exchange assembly 21. The telescopic adjustment groove 237, the push block 238, and the second compression spring 239 of the gas storage cylinder 231 ensure the stable opening of the sealing valve plate 233. When the gas pressure is lower than the tension of the first compression spring 232, the first compression spring 232 resets the sealing valve plate 233, allowing the heat exchange cylinder body 211 to open. Hot water pipe 215 is connected to circulating pump 244 inside the refrigeration box 24. One set is responsible for drawing the waste gas decomposition liquid 242 in the purification cavity 241 into the heat exchange cylinder 211, and the other set is responsible for discharging the waste gas decomposition liquid 242 after heat exchange back into the purification cavity 241. High-temperature toxic and harmful gases come into contact with low-temperature waste gas decomposition liquid 242 through spiral heat exchange pipe 214 to achieve rapid cooling. The cooled gas is discharged into the waste gas decomposition liquid 242 in the purification cavity 241 through exhaust pipe 213 to complete the decomposition and purification of the gas.

[0082] As one embodiment of the present invention, such as Figures 2 to 11 As shown, the top of the pyrolysis chamber 1 is provided with a discharge port 5 on both sides. The side of the pyrolysis chamber 1 near the discharge port 5 is provided with a first transmission assembly 6. The first transmission assembly 6 includes a transmission mounting shell 61. Two sets of transmission gears 62 are rotatably connected inside the transmission mounting shell 61. The two sets of transmission gears 62 are meshed together. A crushing shaft 63 is installed at one end of each set of transmission gears 62. A third transmission component 64 is also provided at one end of one set of transmission gears 62 and the second transmission assembly 7. The third transmission component 64 installed on one side of the transmission gear 62 is connected to the output end of the drive motor 42.

[0083] A second transmission assembly 7 is installed in the middle of one side of the pyrolysis chamber 1. The second transmission assembly 7 includes a fixed base plate 71. A cam 72 is provided on the side of the fixed base plate 71 away from the third transmission member 64. The cam 72 and the third transmission member 64 are connected by transmission. Filter holes 8 are also provided on both sides of the pyrolysis chamber 1 near the second transmission assembly 7.

[0084] During operation, the drive motor 42 synchronously drives two sets of second transmission components 46 to rotate in opposite directions via the transmission base plate 43 and the meshing drive gear 44. These transmission components are connected to the third transmission component 64 and the first transmission component 45 via transmission belts and toothed belts, thereby driving the conveyor belt 32 and the crushing shaft 63. The chemical solid residue is fed into the discharge port 5 by the conveyor belt 32, crushed by the crushing shaft 63, and screened by the V-shaped screen plate 12. The V-shaped screen plate 12 allows smaller residues to fall into the high-temperature decomposition area. On component 13, larger residues are discharged into the diversion hood 122 through the collection trough 121, and finally discharged from the pyrolysis chamber 1 through the discharge pipe 14. This process prevents incomplete decomposition caused by large-volume residues and blockage of the high-temperature decomposition component 13. After the large-volume residues are discharged, they are returned to the conveyor belt 32 through other conveying devices, and crushed again by the crushing shaft 63 until they can pass through the filter screen of the V-shaped sieve plate 12. This cyclic treatment ensures that all chemical solid residues are effectively treated.

[0085] As one embodiment of the present invention, such as Figures 3 to 10 As shown, the feeding mechanism 3 includes a metal housing 31, a conveyor belt 32 is installed inside the metal housing 31, and a third transmission component 33 is also provided on one side of the conveyor belt 32 and the metal housing 31.

[0086] A mechanical transmission mechanism 4 is also connected to the top side of the pyrolysis chamber 1. The mechanical transmission mechanism 4 includes a metal cover 41. A drive motor 42 is installed on the outer side of the metal cover 41. A transmission base plate 43 is connected to one side of the metal cover 41. Two sets of drive gears 44 are rotatably connected to the inner center of the transmission base plate 43. The two sets of drive gears 44 are meshed together. One set of drive gears 44, the third transmission component 33, and the negative pressure adsorption component 22 are all equipped with a first transmission component 45. The first transmission component 45 is connected to the output end of the drive motor 42. The two sides of the two sets of drive gears 44 are also connected to a second transmission component 46.

[0087] The interior of the pyrolysis chamber 1 is provided with a decomposition cavity 11. Limiting grooves 111 are provided on both sides of the top of the decomposition cavity 11. Two sets of guide plate grooves 112 are provided on both sides of the inner wall of the two sets of limiting grooves 111. The guide plate grooves 112 and guide plates 123 are structurally matched and are slidably fitted. Four sets of oscillation guide grooves 113 are provided on both sides of the bottom of the decomposition cavity 11. A V-shaped screen plate 12 is installed on the top of the inner cavity of the decomposition cavity 11. A collection slot 121 is provided in the middle of the V-shaped screen plate 12. A flow guide hood 122 is installed on the bottom of the V-shaped screen plate 12. The flow guide hood 122 is connected to the discharge pipe 14. Two sets of guide plates 123 are also provided at both ends of the V-shaped screen plate 12.

The high-temperature decomposition assembly 13 includes a first screening plate frame 131. Pushing arm plates 132 are connected to the bottom of both sides of the first screening plate frame 131. A second screening plate frame 133 is provided at the bottom of the first screening plate frame 131. Vibration guide seats 134 are provided on both ends of the second screening plate frame 133 and the first screening plate frame 131. The vibration guide groove 113 and the vibration guide seat 134 are structurally matched and are in sliding fit. The interiors of the second screening plate frame 133 and the first screening plate frame 131 are also respectively provided with The device includes a high-temperature decomposition component 135, which includes an electric heating substrate 1351. Both ends of the electric heating substrate 1351 are equipped with micro motors 1352. The two sets of micro motors 1352 are connected by a positive and negative screw 1353. An adjustment baffle 1354 is provided inside the electric heating substrate 1351. Both ends of the adjustment baffle 1354 are threaded to the positive and negative screw 1353. Multiple sets of material passage holes 1355 are opened through the adjustment baffle 1354 and the top of the electric heating substrate 1351. A discharge pipe 14 is also connected to the outer side of the pyrolysis chamber 1 away from the second transmission component 7.

[0089] During operation, the micro motor 1352 controls the movement of the adjusting baffle 1354 inside the electric heating substrate 1351 via the forward and reverse screws 1353. When the forward and reverse screws 1353 rotate clockwise, the adjusting baffle 1354 blocks the chemical solid residue falling from the V-shaped sieve plate 12, preventing it from passing through the electric heating substrate 1351. After the electric heating substrate 1351 is energized, it generates high temperature and performs thermal decomposition treatment on the residue. Rotating the forward and reverse screws 1353 counterclockwise resets the adjusting baffle 1354, allowing the residue to fall through the feed hole 1355 onto the electric heating substrate 1351 inside the second screening plate frame 133. The design and function of the second screening plate frame 133 are the same as those of the first screening plate frame 131. Therefore, the dual thermal decomposition treatment of chemical solid residue can be achieved through repeated operation.

[0090] Working Principle: The chemical solid waste treatment equipment designed in this invention mainly consists of a pyrolysis chamber 1, a gas treatment mechanism 2, a feeding mechanism 3, and a mechanical transmission mechanism 4. The mechanical transmission mechanism 4 includes a metal cover 41, a drive motor 42, a transmission base plate 43, drive gears 44, a first transmission component 45, and a second transmission component 46. This mechanical transmission mechanism 4 can transmit power to the first transmission component 6, the second transmission component 7, the third transmission component 33, and the negative pressure adsorption component 22 via transmission belts and toothed belts. When the drive motor 42 is energized, it drives one set of drive gears 44 mounted on one side of the transmission base plate 43 to rotate. Because the two sets of drive gears 44 are meshed, and each set of drive gears 44 is connected to a second transmission component 46 on one side, the drive motor 42 can synchronously drive the two sets of second transmission components 46 to rotate in opposite directions. This is achieved by connecting one set of drive gears 62 to one end of the second transmission component 7. The added third transmission component 64 is connected to the second transmission component 46 by a transmission belt, and the first transmission component 45 is connected to the third transmission component 64 at one end of the transmission gear 62 by a transmission toothed belt. The drive motor 42 can synchronously drive the conveyor belt 32 in the feeding mechanism 3 to rotate through the transmission belt and the transmission toothed belt. At the same time, the two sets of crushing shafts 63 installed inside the feeding port 5 can also be driven to rotate through the transmission belt and the transmission toothed belt. When the conveyor belt 32 is running, it can send the chemical solid residue to be processed into the feeding port 5 opened on both sides of the top of the pyrolysis chamber 1. When the two sets of crushing shafts 63 installed inside the feeding port 5 rotate, they can crush the chemical solid residue conveyed from the conveyor belt 32. At this time, the crushed chemical solid residue is filtered, screened and discharged through the V-shaped screen plate 12 installed on the top of the decomposition cavity 11.

[0091] The V-shaped sieve plate 12 in this design consists of a collection slot 121, a flow guide hood 122, and a guide plate 123. When chemical solid residues pass through the filter screen of the V-shaped sieve plate 12, smaller chemical solid residues can fall onto the high-temperature decomposition assembly 13 through the filter screen, while larger chemical solid residues are discharged into the flow guide hood 122 through the collection slot 121. Since the flow guide hood 122 and the discharge pipe 14 are connected, the chemical solid residues collected in the flow guide hood 122 can be discharged from the inside of the pyrolysis chamber 1 through the discharge pipe 14, preventing larger chemical solid residues from falling into the high-temperature decomposition assembly 13. The high-temperature decomposition component 13 avoids the situation where the chemical solid residue is too large, resulting in incomplete decomposition of the internal chemical compound crystals. It also prevents blockage accidents caused by the large volume of the chemical solid residue in the high-temperature decomposition component 13. It should be noted that the large chemical solid residue filtered by the V-shaped screen plate 12 will be discharged outward through the discharge pipe 14. After being discharged, the large chemical solid residue will be transported back to the conveyor belt 32 by other conveying devices, and then crushed again by the crushing shaft 63 until the chemical solid residue to be processed can pass smoothly through the filter screen of the V-shaped screen plate 12.

[0092] The gas handling mechanism 2 in this solution consists of a heat exchange component 21, a negative pressure adsorption component 22, a pressure storage component 23, and a refrigeration box 24. The negative pressure adsorption component 22 adopts the existing negative pressure pump structure and is composed of components such as a negative pressure housing and an impeller. When the impeller rotates inside the negative pressure housing, the transition fit between the impeller and the housing forms a sealed space, and a negative pressure effect is generated by the high-speed rotation of the impeller. During this process, external air is drawn in through the suction port of the negative pressure housing. Driven by the impeller, the air is continuously drawn into the negative pressure housing and compressed. The first transmission component 45 and the second transmission component are installed at one end of the negative pressure adsorption component 22. A transmission toothed belt is connected to the third transmission component 64 installed at one end of the second transmission component 7, and a transmission toothed belt is connected to the third transmission component 64 installed at one end of one set of drive gears 44. When the drive motor 42 is powered on, the transmission belt and the transmission toothed belt can drive the suction impeller installed inside the negative pressure housing to rotate. The rotating suction impeller inside the negative pressure housing can draw the toxic and harmful gases generated by the thermal decomposition of chemical synthesis crystals into the pressure storage component 23 in the first time, which can effectively prevent the toxic and harmful gases generated by the thermal decomposition of chemical synthesis crystals from overflowing out of the thermal decomposition chamber 1.

[0093] The pressure accumulator assembly 23 of this scheme consists of a gas storage cylinder 231, a first compression spring 232, a sealing valve plate 233, a sealing retaining ring 234, an inductive switch 235, a contact switch 236, a telescopic adjustment groove 237, a push block 238, and a second compression spring 239. The gas storage cylinder 231 can temporarily store the toxic and harmful gases transported by the negative pressure adsorption assembly 22. When the toxic and harmful gases stored inside the gas storage cylinder 231 reach a certain value, causing the internal pressure to exceed the tension of the first compression spring 232, the higher-pressure toxic and harmful gases stored inside the gas storage cylinder 231 can push the sealing valve plate 233 attached to one end of the first compression spring 232. When the sealing valve plate 233 is opened by the toxic and harmful gases, the temporarily stored toxic and harmful gases inside the gas storage cylinder 231 are released. Gas can be released instantly into the heat exchange component 21. Through the telescopic adjustment groove 237, the push block 238, and the second compression spring 239 respectively set on both sides of one end of the gas storage cylinder 231, the push block 238 can temporarily limit the gap of the opened sealing valve plate 233 under the outward push of the second compression spring 239, so as to keep the sealing valve plate 233 continuously open and prevent the sealing valve plate 233 from opening and closing unstablely during the gas pressure change. When the gas pressure inside the gas storage cylinder 231 is less than the tension of the first compression spring 232, the sealing valve plate 233 can squeeze and reset the push block 238 pushed at the gap of the sealing valve plate 233 under the tension of the first compression spring 232, so that the sealing valve plate 233 can be reset at one end inside the gas storage cylinder 231.

[0094] This solution utilizes inductive switches 235 installed at both ends of the sealing ring 234 and contact switches 236 installed on both sides of one end of the gas storage cylinder 231. Since the inductive switches 235 and 236 are electrically connected to the micro motors 1352 installed on both sides of the uniformly heated substrate 1351, in the initial state, the sealing valve plate 233 is always in contact with the inductive switches 235. When the sealing valve plate 233 contacts the inductive switches 235 to reset the horizontally aligned feed hole 1355, it can control the micro motors 1352 to drive the positive... When the reverse screw 1353 rotates clockwise a certain number of times, and the micro motor 1352 drives the output end of the reverse screw 1353 to rotate clockwise, it can drive the adjusting baffle 1354, which is threadedly connected to the reverse screw 1353, to move inside the electric heating plate 1351. This prevents the material passage hole 1355 through the surface of the electric heating plate 1351 and the adjusting baffle 1354 from being horizontally aligned. Therefore, the adjusting baffle 1354 can block the chemical solid residue falling from the V-shaped sieve plate 12 during this process, preventing the chemical solid residue from directly passing through the first sieve plate 12. An electrically heated base plate 1351 installed in the first screening plate frame 131 rests on an electrically heated base plate 1351 installed in the second screening plate frame 133. When the electrically heated base plate 1351 installed in the first screening plate frame 131 is energized, it can generate extremely high temperatures to thermally decompose chemical solid residues. Similarly, when the sealing valve plate 233 contacts the contact switch 236, it can control the micro motor 1352 to drive the positive and negative screws 1353 installed at the output end to rotate counterclockwise a certain number of times. The positive and negative screws 1353 rotating counterclockwise a certain number of times can heat the electrically heated base plate. The adjustment baffle 1354 inside the plate 1351 can be moved so that the electric heating plate 1351 and the material passage hole 1355 through the surface of the adjustment baffle 1354 are horizontally aligned. At this time, the chemical solid residue can fall into the electric heating plate 1351 installed in the second screening plate frame 133 through the two sets of horizontally aligned material passage holes 1355. The second screening plate frame 133 and the electric heating plate 1351 installed inside it have the same structure as the first screening plate frame 131 and the electric heating plate 1351 installed inside it, so that the chemical solid residue can be subjected to dual thermal decomposition treatment.

[0095] As can be seen from the above, this solution can effectively overcome the problem of incomplete decomposition of chemically synthesized crystals inside chemical solid residues. In this solution, the mesh size of the V-shaped sieve plate 12 is the same as the mesh size of the electric heating substrate 1351 installed in the first screening plate frame 131, which can ensure that the chemical solid residues falling from the V-shaped sieve plate 12 will not cause blockage of the electric heating substrate 1351 installed in the first screening plate frame 131. By installing the electric heating substrate 1351 in the second screening plate frame 133, and the second screening plate frame 133 and the electric heating substrate 1351 installed inside it having the same structure as the first screening plate frame 131 and the electric heating substrate 1351 installed inside it, the falling chemical solid residues can be subjected to dual thermal decomposition treatment, thereby improving the working efficiency of the equipment in thermal decomposition of chemical solid residues.

[0096] This solution uses a second transmission component 7 installed in the middle of one side of the pyrolysis chamber 1. The second transmission component 7 consists of a fixed base plate 71 and a cam 72. A third transmission component 64 installed at one end of the second transmission component 7 is connected to a first transmission component 45 installed at one end of one set of drive gears by a transmission belt. When the drive motor 42 is powered on, it can drive the cam 72 connected to one end of the third transmission component 64 to rotate synchronously. The rotating cam 72 can move the bottom side of the V-shaped sieve plate 12 installed inside the pyrolysis chamber 1 and the top side of the first screening plate frame 131. Since the V-shaped sieve plate 12 is slidably connected to the top of the decomposition cavity 11 through the structure of guide plate groove 112 and guide plate 123, the V-shaped sieve plate 12 can screen the chemical solid residues that are guided by the filter screen surface, which can prevent the chemical solid residues from adhering to or clogging on the filter screen surface of the V-shaped sieve plate 12.

[0097] In this design, the first screening plate frame 131 and the second screening plate frame 133 are connected to the bottom of the decomposition cavity 11 by means of vibration guide seats 134 installed at both ends and vibration guide grooves 113 opened on both sides of the bottom of the cavity 11. Since the vibration guide grooves 113 and the vibration guide seats 134 are in sliding fit, the first screening plate frame 131 and the second screening plate frame 133 can be slidably connected to the bottom of the decomposition cavity 11. The vibration guide seat 134 is composed of a guide slider and a support spring. The support spring can provide upward support for the bottom of the guide slider that is slidably connected in the vibration guide groove 113. When the rotating cam 72 moves the V-shaped screen plate 12 and the first screening plate frame 131, the first screening plate frame 131 moves in the vibration guide groove 113 and the guide slider. Under the action of the support spring, it can vibrate up and down at the bottom of the decomposition cavity 11. The support spring can also amplify the up and down vibration of the first screening plate frame 131, which can increase the frequency of the up and down vibration of the first screening plate frame 131 at the bottom of the decomposition cavity 11. The first screening plate frame 131 can also drive the second screening plate frame 133 to vibrate through the push arm plates 132 installed on both sides of the bottom. The first screening plate frame 131 and the second screening plate frame 133 in the vibrating state can vibrate the electric heating base plate 1351 installed inside. This can prevent chemical solid residues from adhering to and clogging the material passage holes 1355 of the two sets of electric heating base plates 1351, while also improving the efficiency of the thermally decomposed chemical solid residues passing through the material passage holes 1355.

[0098] The heat exchange assembly 21 designed in this scheme consists of a heat exchange cylinder 211, an inlet pipe 212, an exhaust pipe 213, a spiral heat exchange tube 214, and a heat exchange water tube 215. Two sets of heat exchange water tubes 215 are installed on both sides of the heat exchange cylinder 211 and connected to a circulating pump 244 inside the refrigeration chamber 24. One set of heat exchange water tubes 215 and the circulating pump 244 is responsible for drawing the decomposed waste gas liquid 242 after refrigeration treatment inside the purification cavity 241 into the interior of the heat exchange cylinder 211, while the other set is responsible for circulating the waste gas liquid 242 after heat exchange in the heat exchange cylinder 211. The waste gas decomposition liquid 242 is discharged back into the purification cavity 241. When the high-temperature toxic and harmful gas is discharged from the gas storage cylinder 231 into the spiral heat exchange tube 214 installed inside the heat exchange cylinder 211, the spiral heat exchange tube 214, together with the low-temperature waste gas decomposition liquid 242 circulating inside the heat exchange cylinder 211, can quickly cool the high-temperature toxic and harmful gas. The cooled toxic and harmful gas is discharged through the exhaust pipe 213 into the waste gas decomposition liquid 242 filled inside the purification cavity 241, thereby achieving the decomposition and purification of the toxic and harmful gas.

[0099] It should be noted that the chemical solid residue in this solution will produce toxic organic compounds and gaseous substances, such as dioxins, under the high-temperature thermal decomposition of the electrically heated substrate 1351. The waste gas decomposition liquid 242 filled inside the purification cavity 241 is an oxidant solution, specifically a sodium hypochlorite solution, which can effectively neutralize toxic and harmful gases such as dioxins, thus avoiding air pollution and environmental damage caused by the high-temperature thermal decomposition of chemical solid residues by this equipment.
