Description

Technical Field

[0001] The invention relates to the technical field of chemical solid waste treatment, in particular to a treatment device for chemical production solid waste. Background Art

[0002] In the chemical production process, the interaction between catalysts and chemical raw materials often generates a large amount of solid residues. The surface of these solid residues is usually adhered to the crystals of chemical synthesis, which may contain harmful components. If they are directly disposed of without treatment, they will cause potential pollution to the soil and the environment during subsequent treatment processes such as soil landfill. In order to ensure the harmless treatment of these wastes, the crystals of chemical synthesis attached to the surface of the residues must be further treated. A common practice is to decompose the chemical components in the crystals into harmless substances through a thermal decomposition process. This process can significantly reduce the harmful components in solid wastes, thereby ensuring that there will be no chemical pollution to the environment during soil landfill. Thermal decomposition treatment can not only reduce the cost of waste treatment, but also lay the foundation for its subsequent resource utilization.

[0003] At present, the existing chemical solid residue processing equipment usually lacks the function of effectively crushing the pre-treated chemical solid residue during use, and when the crushed chemical solid residue is screened, the screening may not be thorough. At the same time, the existing processing equipment has not yet been able to achieve accurate and controllable screening when performing high-temperature thermal decomposition of chemical solid residue, which may cause some chemical synthetic crystals inside the solid residue to not be completely decomposed during the pollution-free treatment process. In this process, the thermal decomposition screen may also be easily blocked.

[0004] Based on this, we propose a chemical production solid waste treatment equipment to solve the above-mentioned problems. Summary of the invention

[0007] Based on the above technical features, the chemical solid waste treatment equipment designed in the present invention is mainly composed of a thermal decomposition box, a gas treatment mechanism, a feeding mechanism and a mechanical transmission mechanism, wherein the mechanical transmission mechanism includes a metal cover, a drive motor, a transmission base plate, a drive gear, a first transmission member and a second transmission member. The mechanical transmission mechanism can transmit the first transmission component, the second transmission component, the third transmission component and the negative pressure adsorption component through a transmission belt and a transmission toothed belt. When the third transmission component is operated through the mechanical transmission mechanism, the chemical solid residue to be treated can be fed into the feeding port opened on both sides of the top of the thermal decomposition box through the feeding conveyor belt. When the first transmission component is operated 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 through a V-shaped sieve plate installed on the top of the decomposition cavity while being screened.

[0008] Preferably, in the above-mentioned chemical production solid waste treatment equipment, limit stop grooves are opened on both sides of the top of the decomposition cavity, and two groups of guide plate grooves are opened on both sides of the inner walls of the two groups of limit stop grooves, and the guide plate grooves match the guide card plate structure, and the guide plate grooves and the guide card plate are in a sliding fit, and four groups of oscillation guide grooves are opened on both sides of the bottom of the decomposition cavity, and the oscillation guide grooves match the oscillation guide seat structure, and the oscillation guide grooves and the oscillation guide seat are in a sliding fit.

[0009] Based on the above technical features, the limit stop groove and guide plate groove on the top of the decomposition cavity slide together with the guide card plate to ensure the stable installation and precise positioning of the V-shaped screen plate. This limit design helps to prevent the V-shaped screen plate from offset or shifting during use, thereby ensuring the stability and accuracy of screening. The sliding cooperation between the oscillation guide groove at the bottom and the oscillation guide seat can transmit the 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 the screening efficiency and avoiding the occurrence of blockage problems.

[0010] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the unloading mechanism includes a metal shell, a feed conveyor belt is installed inside the metal shell, and a third transmission assembly is also provided between the feed conveyor belt and one side of the metal shell.

[0011] Based on the above technical features, the feed conveyor belt in the unloading mechanism is responsible for conveying the chemical solid residue to be processed to the unloading port on the top of the thermal decomposition box. The setting of the feed conveyor belt ensures the continuous and smooth transportation of the residue, helps to improve the processing efficiency, and avoids the accumulation or jamming of the residue during the transportation process.

[0012] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the mechanical transmission mechanism includes a metal cover body, a driving motor is installed on the outer side of the metal cover body, and a transmission substrate is connected to one side of the metal cover body. The inner middle part of the transmission substrate is rotatably connected to two groups of driving gears, and the two groups of driving gears are meshed. One end of one group of driving gears, the third transmission assembly and the negative pressure adsorption assembly are all installed with a first transmission member, and the first transmission member is transmission-connected to the output end of the driving motor, and the two sides of the two groups of driving gears are also transmission-connected with second transmission members respectively.

[0013] 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 the drive gear, the power is transmitted from the output end of the drive motor to each transmission component. The first transmission member is connected to the output end of the drive motor. Through the meshing movement of the drive gear, the power is evenly distributed, providing sufficient power support for each part of the equipment.

[0014] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the first transmission assembly includes a transmission mounting shell, and two groups of transmission gears are rotatably connected inside the transmission mounting shell, and the two groups of transmission gears are meshingly connected. A crushing shaft is installed at one end of the two groups of transmission gears, and a third transmission member is also provided at one end of one group of transmission gears and the second transmission assembly.

[0015] Based on the above technical features, a crushing shaft is connected to the end of the transmission gear. Through the 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, which can effectively reduce the particle size of the residue and improve the efficiency of subsequent screening and thermal decomposition.

[0016] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the second transmission assembly includes a fixed base plate, a cam is provided on the side of the fixed base plate away from the third transmission member, and the cam is transmission-connected to the third transmission member.

[0017] Based on the above technical features, the present solution has a cam installed on one side of the fixed base plate. When the cam is in a rotating state, it can move the V-shaped screen plate and the first screening plate frame. The V-shaped screen plate can screen the chemical solid residues guided by the filter mesh surface, thereby preventing the chemical solid residues from adhering to or clogging the filter mesh surface of the V-shaped screen plate. Similarly, the first screening plate frame in the moved state can drive the second screening plate frame to shake through the pushing arm plates installed at the bottom of both sides. The first screening plate frame and the second screening plate frame in the shaking state can shake the electric heating base plates installed inside them, thereby preventing the chemical solid residues from adhering to and clogging the material holes of the two sets of electric heating base plates, while also improving the efficiency of the thermally decomposed chemical solid residues passing through the material holes.

[0018] 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 two sides of the outside of the heat exchange cylinder.

[0019] Based on the above technical features, this solution uses the structural design of the spiral heat exchange tube to form a long path flow of the high-temperature gas in the pipe, which not only prolongs the contact time between the high-temperature gas and the cooling water, but also improves the heat transfer efficiency. At the same time, hot water pipes are connected to both sides of the heat exchange cylinder, so that cooling water can enter from the outside and take away the heat.

[0020] Preferably, in the above-mentioned chemical production solid waste treatment equipment, a purification cavity is opened inside the refrigeration box, the interior of the purification cavity is filled with waste gas decomposition liquid, and an installation cavity is opened near the top of the purification cavity of the refrigeration box, and two groups of circulation pumps are arranged inside the installation cavity, and the two groups of circulation pumps are respectively connected to the middle of the hot water exchange pipe, and an exhaust valve is also arranged on the external side of the refrigeration box, and the exhaust valve and the purification cavity are through-connected.

[0021] Based on the above technical features, this solution sets up a purification cavity inside the refrigeration box and fills it with exhaust gas decomposition liquid. When the exhaust gas is discharged through the heat exchange component, the purification cavity allows the harmful components in the exhaust gas to react chemically with the exhaust gas decomposition liquid, thereby effectively decomposing the harmful substances. This design ensures that the exhaust gas is purified, greatly reduces its harm to the environment, and enhances the environmental performance of the equipment.

[0022] Preferably, in the above-mentioned chemical production solid waste treatment equipment, the discharge 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.

[0023] Based on the above technical features, the discharge port of the exhaust pipe is located at the bottom of the purification cavity, which means that the gas discharged from the heat exchange system can fully contact with the exhaust gas decomposition liquid. Since the exhaust gas usually contains harmful substances, the position of the exhaust pipe ensures that these gases can be fully reacted with the decomposition liquid at the bottom of the purification cavity when discharged through the bottom. Through this design, the harmful components in the exhaust gas can be effectively decomposed to achieve the purpose of purification. The air inlet port of the exhaust valve is located at the top of the purification cavity, utilizing the buoyancy principle of the gas. By setting the air inlet port at the top, the harmless gas after the reaction can be discharged in time during the purification process to prevent the gas from accumulating inside the cavity and causing excessive pressure.

[0024] 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.

[0025] Based on the above technical features, sodium hypochlorite solution, as a commonly used oxidant, can decompose harmful components in exhaust gas through strong oxidation, especially organic matter, sulfides or other reducing harmful substances. Treatment with sodium hypochlorite solution can quickly oxidize pollutants in exhaust gas and convert them into harmless substances, thereby ensuring the safety of exhaust gas.

[0026] The present invention provides a treatment device for solid waste from chemical production, which has the following technical points and beneficial effects: 1. This equipment realizes the crushing function of the chemical solid residue after pretreatment through the mechanical transmission mechanism, which effectively solves the problem of lack of crushing treatment in the existing equipment. The crushing shaft cooperates with the drainage and filtering function of the V-shaped screen plate to screen the crushed residue to ensure that the residue has reached the ideal particle size before entering the subsequent thermal decomposition treatment link. This not only improves the uniformity of residue treatment, but also reduces the blockage problem caused by uncrushed large particles. The chemical solid residue with a relatively large volume filtered out by the crushing shaft through the V-shaped screen plate can also be discharged outward using the discharge pipe. The chemical solid residue with a relatively large volume after discharge can be transported to the feed conveyor belt through other feeding devices, and crushed again using the crushing shaft until the chemical solid residue to be treated passes smoothly through the filter mesh surface of the V-shaped screen plate, which can provide a stable foundation for the continuous operation of the equipment.

[0027] 2. The V-shaped screen plate in this scheme is responsible for the preliminary screening of the crushed chemical solid waste in the equipment. Its design consists of a collection slot, a drainage hood and a guide card to ensure that smaller waste can directly enter the high-temperature decomposition component through the filter screen, while larger waste is discharged through the collection slot and the drainage hood. The drainage hood is connected to the discharge pipe, so that larger waste can be quickly discharged to prevent blockage. This screening process not only ensures the smooth progress of high-temperature decomposition, but also avoids incomplete decomposition of waste due to excessive volume, thereby improving the operating stability of the equipment.

[0028] 3. Through the scientific design of the screening plate frame and the electric heating base 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 enables the electric heating base plate to regulate the passage of chemical solid residues at different stages. Driven by a micro motor, the adjusting baffle prevents the residue from falling prematurely when necessary, and avoids excessive untreated particles in the high-temperature decomposition zone. This not only optimizes the thermal decomposition effect of the residue, but also effectively prevents the occurrence of blockage problems, ensuring that the equipment can maintain stable operating performance under high temperature processing.

[0029] 4. The negative pressure adsorption component in this scheme operates synchronously through a mechanical transmission mechanism to suck the toxic gas generated by thermal decomposition into the pressure storage component, and then the gas is transported to the heat exchange component for cooling through the adjustment of the compression spring. The heat exchange component is composed of a spiral heat exchange tube and a low-temperature exhaust gas decomposition liquid, which can effectively reduce the gas temperature and prevent the toxic gas from diffusing in a high temperature environment. The cooled gas further enters the sodium hypochlorite solution through the exhaust pipe for neutralization. This design ensures the multiple safety and effectiveness of the gas treatment process, avoids the pollution of the equipment to the external environment, and improves the efficiency of gas cooling and purification.

[0030] 5. This scheme ensures the thorough decomposition of chemical solid residues through the dual decomposition structure of the first screening plate frame, the second screening plate frame and the electric heating substrate. The electric heating substrate in the first screening plate frame performs preliminary decomposition of the chemical residues by adjusting the baffle under the control of the micro motor. This dual decomposition process not only solves the problem of incomplete decomposition of chemical synthetic crystals, but also prevents the blockage of the screen plate and the heating substrate, further improves the efficiency of high-temperature decomposition, and ensures the safety and thoroughness of the chemical solid waste treatment process.

[0037] When working, the gas storage cylinder 231 is used to store toxic and harmful gases.

[0044] A high-temperature decomposition component 13 is arranged at the bottom of the inner cavity of the decomposition cavity 11, and the high-temperature decomposition component 13 includes a first screening plate frame 131, and the bottoms of both sides of the first screening plate frame 131 are connected with push arm plates 132, and the bottom of the first screening plate frame 131 is provided with a second screening plate frame 133, and the second screening plate frame 133 and both ends of the first screening plate frame 131 are provided with oscillation guide seats 134, and the oscillation guide groove 113 matches the oscillation guide seat 134 structure, and the oscillation guide groove 113 and the oscillation guide seat 134 are slidably matched, and the second screening plate frame 133 and the first screening plate frame 131 are also respectively provided with There is a high-temperature decomposition component 135, which includes an electric heating substrate 1351. Micro motors 1352 are arranged on both sides of the two ends of the electric heating substrate 1351. A forward and reverse screw 1353 is transmission-connected between the two groups of micro motors 1352. An adjusting baffle 1354 is arranged inside the electric heating substrate 1351. Both ends of the adjusting baffle 1354 and the forward and reverse screws 1353 are threadedly matched. Multiple groups of material passing holes 1355 are penetrated through the top of the adjusting baffle 1354 and the electric heating substrate 1351. A discharge pipe 14 is also connected to the external side of the thermal decomposition box 1 away from the second transmission component 7.

[0045] During operation, the micro motor 1352 controls the movement of the adjusting baffle 1354 inside the electric heating substrate 1351 through the forward and reverse screws 1353. When the forward and reverse screws 1353 rotate clockwise, the adjusting baffle 1354 will block the chemical solid residue falling from the V-shaped screen plate 12 to prevent it from passing through the electric heating substrate 1351. After the electric heating substrate 1351 is powered on, high temperature is generated to thermally decompose the residue. Counterclockwise rotation of the forward and reverse screws 1353 resets the adjusting baffle 1354 to allow the residue to fall through the material passing hole 1355 onto the electric heating substrate 1351 in 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, so double thermal decomposition of the chemical solid residue can be achieved through repeated operations.

[0046] Working principle: The chemical solid waste treatment equipment designed by the present invention is mainly composed of a thermal decomposition box 1, a gas treatment mechanism 2, a feeding mechanism 3 and a mechanical transmission mechanism 4, wherein the mechanical transmission mechanism 4 includes a metal cover 41, a driving motor 42, a transmission base plate 43, a driving gear 44, a first transmission member 45 and a second transmission member 46. The mechanical transmission mechanism 4 can transmit the first transmission component 6, the second transmission component 7, the third transmission component 33 and the negative pressure adsorption component 22 through a transmission belt and a transmission toothed belt. When the driving motor 42 is powered on, it can drive one of the groups of driving gears 44 installed on one side of the transmission base plate 43 to rotate. Because the two groups of driving gears 44 are meshed and connected, and one side of the two groups of driving gears 44 is respectively connected to the second transmission member 46, the driving motor 42 can synchronously drive the two groups of second transmission members 46 to rotate when it is powered on, and the two groups of second transmission members 46 rotate in opposite directions. By respectively connecting one end of one group of transmission gears 62 and the second transmission component 7, the two groups of second transmission members 46 rotate in opposite directions. A third transmission member 64 is added, wherein a transmission belt is connected between the third transmission member 64 added at one end of the transmission gear 62 and the second transmission member 46, and a transmission toothed belt is connected between the first transmission member 45 added at one end of the third transmission assembly 33 and the third transmission member 64 added at one end of the transmission gear 62. The driving motor 42 can synchronously drive the feed conveyor belt 32 in the unloading mechanism 3 to rotate through the transmission belt and the transmission toothed belt. At the same time, the two groups of crushing shafts 63 installed inside the unloading port 5 can also be driven to rotate through the transmission belt and the transmission toothed belt. When the feed conveyor belt 32 is running, the chemical solid residue to be processed can be sent to the unloading port 5 opened on both sides of the top of the thermal decomposition box 1. When the two groups of crushing shafts 63 installed inside the unloading port 5 rotate, the chemical solid residue transported from the feed conveyor belt 32 can be crushed. At this time, the crushed chemical solid residue is filtered, screened and drained through the V-shaped screen plate 12 installed on the top of the inner cavity of the decomposition cavity 11.

[0047] The V-shaped sieve plate 12 in this solution is composed of a collecting slot 121, a drainage cover 122 and a guide card plate 123. When the chemical solid residue passes through the filter mesh surface of the V-shaped sieve plate 12, the chemical solid residue with a smaller volume can fall onto the pyrolysis component 13 through the filter mesh surface of the V-shaped sieve plate 12, while the chemical solid residue with a larger volume is discharged into the drainage cover 122 through the collecting slot 121. Since the drainage cover 122 and the discharge pipe 14 are connected through, the chemical solid residue collected in the drainage cover 122 can be discharged from the inside of the pyrolysis box 1 by using the discharge pipe 14, which can prevent the chemical solid residue with a larger volume from falling on the pyrolysis box 1. The high-temperature decomposition component 13 avoids the situation in which the chemical solid residues are too large and the internal chemical compound crystals are not completely decomposed due to their large volume. At the same time, it can also prevent the high-temperature decomposition component 13 from being blocked due to the large volume of the chemical solid residues. It should be noted that the chemical solid residues with large volume filtered out by the V-shaped sieve plate 12 will be discharged outward through the discharge pipe 14. After being discharged, the chemical solid residues with large volume will be re-transported to the feed conveyor belt 32 through other feeding devices, and will be re-crushed by the crushing shaft 63 until the chemical solid residue to be processed successfully passes through the filter mesh surface of the V-shaped sieve plate 12.

[0048] The gas processing mechanism 2 in this scheme is composed 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 negative pressure suction pump structure in the prior art, and is composed of a negative pressure shell, a suction impeller and other components. When the suction impeller rotates inside the negative pressure shell, the transition fit between the impeller and the shell forms a closed space, and a negative pressure effect is generated by the high-speed rotation of the impeller. In this process, external air is sucked in through the suction port of the negative pressure shell. After being pushed by the impeller, the air is continuously sucked into the negative pressure shell and compressed. The first transmission member 45 installed at one end of the negative pressure adsorption component 22 and the second transmission component A transmission toothed belt is connected between the third transmission member 64 installed at one end of 7, and a transmission toothed belt is connected between the third transmission member 64 installed at one end of the second transmission assembly 7 and the first transmission member 45 installed at one end of one of the driving 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 shell to rotate. The suction impeller rotating inside the negative pressure shell can draw the toxic and harmful gases generated by the thermal decomposition of the chemical compound crystals into the interior of the pressure storage assembly 23 as soon as possible, which can effectively prevent the toxic and harmful gases generated by the thermal decomposition of the chemical compound crystals from overflowing from the inside of the thermal decomposition box 1.

[0049] The pressure storage component 23 of the present scheme is composed of an air storage cylinder 231, a first compression spring 232, a sealing valve plate 233, a sealing retaining ring 234, an induction switch 235, a contact switch 236, a telescopic adjustment groove 237, a push-up block 238 and a second compression spring 239, wherein the air storage cylinder 231 can temporarily store the toxic and harmful gases transported by the negative pressure adsorption component 22. When the toxic and harmful gas storage inside the air storage cylinder 231 reaches a certain value, so that the air pressure inside the air storage cylinder 231 is greater than the pulling force of the first compression spring 232, the sealing valve plate 233 installed at one end of the first compression spring 232 can be pushed up by the toxic and harmful gas with a relatively high pressure stored inside the air storage cylinder 231. When the sealing valve plate 233 is pushed open by the toxic and harmful gas, the toxic and harmful gas temporarily stored inside the air storage cylinder 231 is released. The gas can be released into the heat exchange component 21 instantly. Through the telescopic adjustment groove 237, the push-up block 238 and the second compression spring 239 respectively arranged on both sides of one end of the gas storage cylinder 231, the push-up block 238 can temporarily limit the gap of the sealing valve plate 233 that is pushed open under the action of the second compression spring 239 pushing outward, so as to keep the sealing valve plate 233 continuously open and prevent the sealing valve plate 233 from opening and closing or other unstable situations during the change of air pressure. When the air pressure inside the gas storage cylinder 231 is less than the pulling force of the first compression spring 232, the sealing valve plate 233 can squeeze and reset the push-up block 238 that pushes up at the gap of the sealing valve plate 233 under the action of the pulling force 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.

[0050] In this solution, the induction switch 235 is respectively installed at both ends of the sealing retaining ring 234, and the contact switch 236 is respectively installed at both sides of one end of the gas storage cylinder 231. Because the induction switch 235 and the contact switch 236 are electrically connected to the micro motors 1352 installed at both ends of the substrate 1351, the sealing valve plate 233 is always in contact with the induction switch 235 in the initial state. When the sealing valve plate 233 contacts the induction switch 235 to reset the horizontally aligned material through hole 1355, the positive displacement switch installed at the output end can be controlled to drive the micro motor 1352 to rotate. The reverse screw 1353 rotates clockwise for a certain number of turns. When the micro motor 1352 drives the forward and reverse screws 1353 installed at the output end to rotate clockwise, the adjusting baffle 1354 threadedly connected to the forward and reverse screws 1353 can be driven to move inside the electric heating substrate 1351, so that the electric heating substrate 1351 and the material passing hole 1355 opened through the surface of the adjusting baffle 1354 cannot be horizontally aligned. Therefore, the adjusting baffle 1354 can block the chemical solid residues falling from the V-shaped screen plate 12 during this process, and can prevent the chemical solid residues from directly passing through the first The electric heating substrate 1351 installed in the first screening plate frame 131 falls on the electric heating substrate 1351 installed in the second screening plate frame 133. When the electric heating substrate 1351 installed in the first screening plate frame 131 is powered on, it can generate ultra-high temperature to thermally decompose the chemical solid residue. Similarly, when the sealing valve plate 233 contacts the contact switch 236, the micro motor 1352 can be controlled to drive the forward and reverse screws 1353 installed at the output end to rotate counterclockwise for a certain number of turns. The forward and reverse screws 1353 that rotate counterclockwise for a certain number of turns can heat the electric heating substrate 1351. The adjusting baffle 1354 inside the plate 1351 can be moved to horizontally align the electric heating substrate 1351 with the material passing holes 1355 opened through the surface of the adjusting baffle 1354. At this time, the chemical solid residue can fall through the two sets of horizontally aligned material passing holes 1355 onto the additional electric heating substrate 1351 installed in the second screening plate frame 133. The second screening plate frame 133 and the additional electric heating substrate 1351 installed inside are consistent in structure with the first screening plate frame 131 and the additional electric heating substrate 1351 installed inside, so that double thermal decomposition treatment of the chemical solid residue can be achieved.

[0051] From the above, it can be seen that the present scheme can effectively overcome the problem of incomplete decomposition of the crystals of chemical synthetic substances inside the chemical solid residue. In the present scheme, the mesh aperture of the V-shaped sieve plate 12 is the same as the mesh aperture of the electric heating substrate 1351 installed in the first screening plate frame 131, which can ensure that the chemical solid residue falling from the V-shaped sieve plate 12 will not cause blockage to 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 internally installed electric heating substrate 1351 are consistent with the first screening plate frame 131 and the internally installed electric heating substrate 1351, the falling chemical solid residue can be subjected to double thermal decomposition treatment, thereby improving the working efficiency of the equipment for thermal decomposition of chemical solid residue.

[0052] The present solution is to install a second transmission assembly 7 in the middle of one side of the thermal decomposition box 1, and the second transmission assembly 7 is composed of a fixed base plate 71 and a cam 72, and a transmission toothed belt is connected between a third transmission member 64 installed at one end of the second transmission assembly 7 and a first transmission member 45 installed at one end of one group of driving gears 44. When the driving motor 42 is powered on, the cam 72 connected to one end of the third transmission member 64 can be driven to rotate synchronously. The rotating cam 72 can move the bottom side of the V-shaped sieve plate 12 installed inside the thermal decomposition box 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 guide plate groove 112 and the guide card plate 123 structure, the V-shaped sieve plate 12 can screen the chemical solid residue guided by the filter screen surface, thereby preventing the chemical solid residue from adhering to or clogging the filter screen surface of the V-shaped sieve plate 12.

[0053] The first screening plate frame 131 and the second screening plate frame 133 in the present scheme are respectively connected to the bottom of the decomposition cavity 11 through the oscillation guide seats 134 installed at both ends and the oscillation guide grooves 113 respectively opened on both sides of the bottom of the decomposition cavity 11. Since the oscillation guide grooves 113 and the oscillation guide seats 134 are slidably matched, 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, wherein the oscillation guide seat 134 is composed of a guide slider and a support spring, and the support spring can play a role of upward support for the bottom of the guide slider slidably connected in the oscillation guide groove 113. When the rotating cam 72 toggles the V-shaped screen plate 12 and the first screening plate frame 131, the first screening plate frame 131 is in the oscillation guide groove 113 and the guide slider. Under the action of the supporting spring, it can shake up and down at the bottom of the decomposition cavity 11, and the supporting spring can also amplify the up and down shaking of the first screening plate frame 131, which can increase the frequency of the up and down shaking of the first screening plate frame 131 at the bottom of the decomposition cavity 11, and the first screening plate frame 131 can also drive the second screening plate frame 133 to shake through the pushing arm plates 132 installed at the bottom of both sides. The first screening plate frame 131 and the second screening plate frame 133 in the shaking state can shake the electric heating substrate 1351 installed inside them, which can prevent chemical solid residues from adhering to and clogging the through holes 1355 of the two groups of electric heating substrates 1351, and can also improve the efficiency of the thermally decomposed chemical solid residues passing through the through holes 1355.

[0054] The heat exchange assembly 21 designed in this scheme is composed of a heat exchange cylinder 211, an air inlet pipe 212, an exhaust pipe 213, a spiral heat exchange tube 214 and a hot water exchange pipe 215. The two groups of hot water exchange pipes 215 are respectively connected to the circulation pump 244 in the refrigeration box 24 through the hot water exchange pipes 215 installed on both sides of the outside of the heat exchange cylinder 211. One group of hot water exchange pipes 215 and the circulation pump 244 are responsible for pumping the waste gas decomposition liquid 242 after the refrigeration treatment in the purification cavity 241 into the interior of the heat exchange cylinder 211, and the other group is responsible for pumping the waste gas decomposition liquid 242 after the heat exchange in the heat exchange cylinder 211. The waste gas decomposition liquid 242 is discharged back into the purification cavity 241. When the toxic and harmful gases containing high temperature are 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 cooperates with the low-temperature waste gas decomposition liquid 242 circulated inside the heat exchange cylinder 211 to quickly cool the high-temperature toxic and harmful gases. The toxic and harmful gases after cooling are discharged into the waste gas decomposition liquid 242 filled in the purification cavity 241 through the exhaust pipe 213 to achieve decomposition and purification of the toxic and harmful gases.

[0055] It should be noted that the chemical solid residue in this scheme will produce toxic organic compounds and gaseous substances, such as dioxins, under the action of high-temperature thermal decomposition of the electric heating substrate 1351, and the waste gas decomposition liquid 242 filled in the purification cavity 241 is an oxidant solution, specifically a sodium hypochlorite solution, which can effectively neutralize toxic and harmful gases such as dioxins, thereby avoiding air pollution and environmental damage caused by the high-temperature thermal decomposition treatment of the chemical solid residue by the equipment.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
