Description

Technical Field

[0001] This application relates to the technical field of thermal cleaning furnaces, and particularly to a large-scale thermal cleaning furnace system. Background Art

[0002] In the chemical manufacturing industry, iron barrels are usually used to contain organic polymers such as resins; the residual materials in such iron barrels contain a large amount of organic substances, as well as nitrogen, sulfur, phosphorus, and halogen elements, and have characteristics such as high viscosity, corrosiveness, acute toxicity, leaching toxicity, flammability, or explosiveness, belonging to hazardous wastes, and are likely to cause short-term or long-term harmful effects on biological groups and the ecological environment. However, if the residues inside such iron barrels are separated, they can also be reused; however, due to the high viscosity and poor solubility of the residues in the barrels, it is difficult to completely separate them from the iron barrels by physical cleaning methods, and corresponding wastewater will also be generated, causing secondary pollution.

[0003] Currently, the means for treating such hazardous waste mainly include crushing + incineration, cleaning and reuse, and thermal cleaning furnace processes. The disadvantages of the direct crushing process are that the crushed materials still remain hazardous waste, and due to the flammability and explosiveness of the residues during the crushing process, deflagration or even explosion is likely to occur; at the same time, although the iron barrels can be rendered harmless after crushing and incineration, their utilization value is reduced; the disadvantages of the cleaning and reuse process are that due to the high viscosity of the residues in the barrels, they often cannot be completely dissolved by effective solvents within a short period of time, there are still residues in the barrels, and the generated wastewater causes secondary pollution; the advantage of the non-crushing pyrolysis incineration process is that the residues in the iron barrels are gasified through a high-temperature pyrolysis process, and the remaining part is residual carbon; the residual carbon is easy to separate from the iron barrels, and at the same time, the iron barrels can be recycled after discharging. Specifically during operation, the intact iron barrels containing hazardous waste are placed on the material cart, and are sent into the furnace for treatment through the material cart. After the hazardous waste is processed, the iron barrels are sent out through the material cart again.

[0004] Regarding the above related technologies, the inventor believes that in the prior art, since the inside of the thermal cleaning furnace is a high-temperature chamber and continuous feeding and discharging cannot be carried out, the thermal energy utilization rate of the thermal cleaning furnace is reduced; at the same time, the temperature of the processed material cart and the iron barrels is relatively high. At this time, when the staff unloads the iron barrels from the carrier vehicle, they are easily scalded, posing a safety hazard. Summary of the Invention

[0005] In order to improve the safety and treatment effect of removing the attachments on the surface of waste iron barrels and improve the thermal energy utilization rate of the thermal cleaning furnace, this application provides a large-scale thermal cleaning furnace system.

[0006] A large-scale thermal cleaning furnace system provided by this application adopts the following technical solutions:

[0007] A large-scale thermal cleaning furnace system includes a furnace body. Inside the furnace body, a first furnace door and a second furnace door are arranged at intervals. The first furnace door and the second furnace door divide the furnace body into a pyrolysis chamber in the middle of the furnace body, a feeding chamber and a discharging chamber respectively located at both ends of the furnace body. A material cart is slidably arranged in the furnace body along the length direction of the furnace body, and a lifting guide rail for the material cart to slide is arranged in the furnace body. Power components for driving the material cart to slide along the length direction of the lifting guide rail are arranged at both ends of the furnace body in the length direction.

[0008] By adopting the above technical solution, during the pyrolysis cleaning operation, the staff first load the metal workpieces into the material cart one by one, and place the corresponding material carts onto the lifting guide rails in the feeding chamber one by one. At the same time, the power component located at one end of the furnace body close to the feeding chamber drives the corresponding material cart into the pyrolysis chamber. Subsequently, the first furnace door and the second furnace door are closed, and the high-temperature environment in the pyrolysis chamber pyrolyzes the high-molecular dirt attached to the surface of the metal workpiece, making it fully carbonized, so as to achieve the cleaning of the metal workpiece.

[0009] After that, the first furnace door and the second furnace door are opened simultaneously, and the driving component located at one end of the furnace body close to the discharging chamber drives the material cart in the pyrolysis chamber into the discharging chamber. At the same time, the driving component located at one end of the furnace body close to the feeding chamber drives the material cart in the feeding chamber into the pyrolysis chamber, and so on, to carry out the next round of cleaning operation. By connecting and setting the feeding chamber and the discharging chamber at the furnace door of the pyrolysis chamber, the situation that the temperature in the pyrolysis chamber is dissipated to the surrounding environment from the furnace door is reduced, thereby narrowing the temperature difference at both ends in the length direction of the pyrolysis chamber, reducing the difference between the temperatures at each part in the thermal cleaning furnace and the actually set temperature, and further effectively improving the effect of cleaning the high-molecular dirt attached to the surface of the metal workpiece by the large-scale thermal cleaning furnace.

[0010] Preferably, the inlet of the feeding chamber is located on one side in the width direction of the furnace body, and a third furnace door is movably arranged at the inlet of the feeding chamber; the outlet of the discharging chamber is located on the same side of the furnace body, and a fourth furnace door is movably arranged at the inlet of the discharging chamber.

[0011] By adopting the above technical solution, setting the third furnace door to seal the feeding chamber and setting the fourth furnace door to seal the discharging chamber helps to reduce the situation that the heat in the pyrolysis chamber is dissipated to the surrounding environment successively through the first furnace door and the feeding chamber or successively through the second furnace door and the discharging chamber, helps to further reduce the temperature difference between each part in the thermal cleaning furnace, and reduces the difference between the temperatures at each part in the thermal cleaning furnace and the actually set temperature, so as to ensure the normal progress of the cleaning operation of the high-molecular dirt attached to the surface of the metal workpiece.

[0012] Preferably, a heat-insulating layer is fixedly laid on the inner wall of the furnace body corresponding to the pyrolysis chamber.

[0013] By adopting the above technical solution, the heat insulation layer is used to reduce the heat loss from the side wall of the pyrolysis chamber to the surrounding environment, which helps to further reduce the error value between the temperatures at various locations in the pyrolysis chamber and the actually set temperature, thus effectively ensuring the normal progress of the pyrolysis process in the furnace body.

[0014] Preferably, an exhaust port is provided on the side wall of the pyrolysis chamber, and the exhaust port is communicated with an external gas treatment device.

[0015] By adopting the above technical solution, during actual operation, after the material truck runs to the pyrolysis chamber, the high-temperature environment in the pyrolysis chamber incinerates and pyrolyzes the polymer contaminants on the surface of the metal workpiece in the material truck; during the pyrolysis process, a large amount of gas containing substances such as S, N, and H is generated in the pyrolysis chamber, and this part of the gas is discharged into the external gas treatment device through the explosion-proof port, so as to balance the pressure inside and outside the furnace body and reduce the occurrence of the furnace body cracking or even exploding due to excessive air pressure in the pyrolysis chamber, which helps to ensure the safety during the use of the thermal cleaning furnace.

[0016] Preferably, a feeding platform is connected and arranged at the entrance of the feeding chamber, and the feeding platform is communicated with the feeding chamber through a feeding slide rail; a discharging platform is connected and arranged at the exit of the discharging chamber, and the discharging platform is communicated with the discharging chamber through a discharging slide rail.

[0017] By adopting the above technical solution, during actual use, after the staff places the material truck on the feeding slide rail at the feeding platform by using a lifting tool, the material truck moves along the feeding slide rail into the feeding chamber; after the material truck enters the discharging chamber, the corresponding power assembly drives the material truck to move along the discharging slide rail onto the discharging platform, and then the staff uses the lifting tool to take the material truck off the discharging platform, thus completing the discharging operation of the material truck; setting the feeding platform helps to improve the convenience for the staff to place the material truck into the feeding chamber; similarly, setting the discharging platform helps to improve the convenience for the staff to take the material truck out of the discharging chamber, thereby effectively improving the working efficiency of the metal workpiece cleaning operation.

[0018] Preferably, the lifting guide rail includes multiple rows of in-furnace wheel groups arranged at intervals in the width direction of the furnace body. Any one of the in-furnace wheel groups includes multiple rollers arranged at intervals in the length direction of the furnace body. The rotation axis of any one of the rollers is parallel to the width direction of the furnace body, and a driving member for driving any one of the rollers to lift is arranged on the furnace body; a transverse track is correspondingly arranged at the bottom of the material truck for any one of the in-furnace wheel groups, and any one of the transverse tracks is erected on the corresponding in-furnace wheel group and is in rolling cooperation with the corresponding roller in the length direction of the furnace body.

[0019] By adopting the above technical solution, with the help of the rolling cooperation between the transverse track and the roller, the sliding movement of the material truck in the furnace body is realized, and the structure is simple, which helps to save the production cost of the enterprise.

[0020] Preferably, a support rod is provided corresponding to any roller in the furnace body, and the length of any support rod is higher than the distance from the feed slide rail to the bottom surface of the furnace body and the distance from the discharge slide rail to the bottom surface of the furnace body; one end of any support rod is rotatably connected to the bottom surface of the furnace body, and the rotation axis of any support rod is parallel to the width direction of the furnace body; adjacent rollers of any wheel group in the furnace are connected by a linkage rod, and the length direction of any linkage rod is parallel to the length direction of the furnace body; any adjacent support rods of adjacent wheel groups in the furnace are coaxially connected by a connecting shaft;

[0022] By adopting the above technical scheme, after the material cart moves along the feed slide rail to the feed chamber, the piston rod of the hydraulic cylinder extends or shortens and drives the connecting rod to rotate, the connecting rod drives the driving rod to rotate, and the driving rod then synchronously drives the connecting shaft to rotate around its own axis, thereby driving the corresponding two support rods to rotate synchronously; since the adjacent support rods of the wheel group in the same furnace are connected by a linkage rod, when any support rod rotates, any support rod of any wheel group in the furnace is driven to rotate until any support rod is vertically arranged; at this time, any roller is higher than the feed slide rail and the discharge slide rail, and the corresponding roller supports the horizontal track at the bottom of the material cart, so that the material cart is separated from the upper surface of the feed slide rail, thereby realizing the steering of the material cart.

[0023] After the material trolley moves into the discharge chamber, the piston rod of the hydraulic cylinder shortens or lengthens, thereby driving the connecting rod to swing in the opposite direction, and the connecting rod drives the driving rod and the supporting rod to rotate in the opposite direction until any roller of the wheel group in the furnace is lower than the discharge slide rail, so that the material trolley is mounted on the discharge slide rail; after that, the material trolley moves along the length direction of the discharge slide rail to one side of the discharge platform, so as to realize the re-steering of the material trolley; the steering structure is simple, which helps to improve the convenience during production, thereby saving the production cost of the enterprise.

[0024] Preferably, a cooling chamber is provided between the discharge chamber and the discharge platform, and a fifth furnace door is movably provided on a side of the cooling chamber close to the discharge platform.

[0025] By adopting the above technical solution, after the material cart enters the cooling chamber along the discharge slide rail, the air cooling device in the cooling chamber blows and quickly cools down the material cart and the workpieces thereon, thereby improving the cooling efficiency of the material cart and the workpieces thereon, and further effectively improving the work efficiency and discharge safety of the pyrolysis cleaning operation of metal workpieces.

[0026] Preferably, a movable gantry for transferring material vehicles is provided between the discharging platform and the feeding platform.

[0027] By adopting the above technical solution, after the material cart runs to the discharging platform, the electric hoist on the mobile gantry is used to lift the material cart, and the material cart is transferred to the corresponding position for unloading. After the cleaned metal workpieces are unloaded from the material cart, the staff reloads the uncleaned metal workpieces into the material cart; then, the electric hoist of the mobile gantry lifts the material cart and transfers it to the feeding platform again, thereby realizing automatic transfer of the material cart, with a high degree of automation, saving time and effort.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. With the help of the first furnace door and the second furnace door, the inner cavity of the furnace body is divided into a pyrolysis chamber in the middle, a feeding chamber and a discharging chamber at both ends, so as to reduce the heat loss from the furnace door to the surrounding environment in the pyrolysis chamber, reduce the temperature difference between various places in the pyrolysis chamber, and effectively improve the effect of large-scale thermal cleaning furnaces in cleaning high-molecular dirt attached to the surface of metal workpieces;

[0074] In this embodiment of the present application, the structures of the second furnace door 121, the third furnace door 112, the fourth furnace door 131 and the fifth furnace door 71 are the same as the installation structure of the first furnace door 111.

[0075] The implementation principle of a large-scale thermal cleaning furnace system in an embodiment of the present application is as follows: when performing pyrolysis cleaning operations, the third furnace door 112 is opened first, and the first furnace door 111 and the second furnace door 121 remain closed, and the electric hoist of the mobile gantry 8 places the material cart 4 loaded with metal workpieces to be cleaned on the feed slide 21 on the feed platform 2; then, the push rod 612 located on the side of the feed platform 2 away from the furnace body 1 pushes the material cart 4 to slide along the feed slide 21 toward the side of the feed chamber 11; after the material cart 4 enters the feed chamber 11 from the feed platform 2 along the feed slide 21, and the transverse track 42 is located directly above the corresponding wheel group 51 in the furnace, the hydraulic cylinder 91 is started, and the piston rod of the hydraulic cylinder 91 is extended or shortened, thereby driving the roller 511 of the lifting guide rail 5 in the feed chamber 11 to rise until any roller 511 is higher than The feed slide rail 21 is used to lift the material cart 4 from the feed slide rail 21, so that the material cart 4 is transferred to the lifting guide rail 5; then, the third furnace door 112 is closed, and the first furnace door 111 and the second furnace door 121 are opened. The push rod 612 located on the side of the feed chamber 11 away from the pyrolysis chamber 12 pushes the material cart 4 to move along the lifting guide rail 5 toward the pyrolysis chamber 12, and the push rod 612 located on the side of the discharge chamber 13 away from the pyrolysis chamber 12 pulls the original material cart 4 in the pyrolysis chamber 12 to move toward the discharge chamber 13; thereby, the replacement of the metal workpiece to be cleaned in the pyrolysis chamber 12 is completed; subsequently, the first furnace door 111 and the second furnace door 121 are closed at the same time, and the high temperature environment of the pyrolysis chamber 12 pyrolyzes the polymer dirt attached to the surface of the metal workpiece, fully carbonizes it, and peels it off from the surface of the metal workpiece, thereby achieving the cleaning of the metal workpiece.

[0076] At the same time, the fourth furnace door 131 and the fifth furnace door 71 are opened, and the lifting guide rail 5 in the discharge chamber 13 descends, causing the material cart 4 to gradually descend onto the discharge slide rail 31; thereafter, driven by the push rod 612 on the side of the discharge platform 3 away from the furnace body 1, the material cart 4 moves along the discharge slide rail 31 toward the cooling chamber 7; the material cart 4 and the workpieces thereon are cooled in the cooling chamber 7 and then pulled onto the discharge platform 3; then, the electric hoist of the mobile gantry 8 lifts the material cart 4, and transports the material cart 4 along the length direction of the mobile gantry 8 crane bridge to the loading and unloading area for unloading and reloading operations; this cycle is repeated until the cleaning operation of all metal workpieces is completed.

[0077] By adopting this method, the heat loss in the pyrolysis chamber 12 to the surrounding environment can be effectively reduced, thereby reducing the difference between the temperature at various locations in the pyrolysis furnace and the actual set temperature, effectively improving the effect of large-scale thermal cleaning furnaces in cleaning high-molecular dirt attached to the surface of metal workpieces and the thermal energy utilization rate of the system; improving the sealing performance of the thermal cleaning furnace's feeding and unloading process, effectively controlling the operating environment in the furnace, and enhancing the safety of the thermal cleaning furnace's operation; at the same time, the metal workpiece pyrolysis cleaning process has a high degree of automation, which effectively saves manpower and improves work efficiency.

[0078] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
