Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature melting of hazardous waste, and specifically to a high-temperature melting device for hazardous waste and its usage method. Background Art

[0002] Hazardous waste contains a large amount of toxic and harmful substances. If not properly treated, it will pose a serious threat to the environment and human health. Currently, the high-temperature melting technology is one of the effective methods for treating hazardous waste. It can cause physical and chemical changes to hazardous waste at high temperatures, fix harmful substances in the glass body, thereby achieving harmless treatment.

[0003] However, the existing high-temperature melting devices for hazardous waste have obvious deficiencies in the material handling process. During the material feeding process, due to the different forms and properties of hazardous waste, problems such as uneven feeding and blockage are likely to occur. This not only affects the treatment efficiency but may also lead to equipment failures. At the same time, for larger-sized hazardous waste, the existing crushing devices often cannot efficiently crush it to a suitable particle size, making it difficult for the material to be fully melted during the subsequent high-temperature melting process, reducing the treatment effect and energy utilization efficiency. Therefore, it is necessary to design and transform the high-temperature melting device for hazardous waste to effectively prevent the phenomena of poor melting efficiency, inconvenient feeding, and easy blockage.

[0012] A high-temperature melting device for hazardous waste and its usage method, comprising the following steps:

[0013] S1: During operation, the hazardous waste is conveyed to the treatment box through the screw conveying assembly. The principle of the screw conveying assembly is that the motor drives the screw conveyor rod to rotate, thereby conveying the hazardous waste evenly and relatively quantitatively into the crushing box. On the one hand, the purpose of quantitative feeding is achieved, and on the other hand, blockage can be avoided through uniform feeding. The hazardous waste enters the crushing box through the treatment box. The first motor is started to drive the crushing rollers to rotate. The two crushing rollers rotate towards each other to crush the hazardous waste. The crushed material falls into the filtering box and is filtered through the filtering box. The qualified material enters the feeding port of the melting assembly through the aggregate hopper and the guiding pipe on the surface of the support frame.

[0014] S2: During the process of the crushing rollers crushing, the second motor drives the adjusting rod to rotate. Since the cross-section of the adjusting rod is elliptical, when the adjusting rod rotates, it can drive the positioning frame to reciprocate up and down in the sliding groove, thereby driving the filtering box to reciprocate up and down, and then driving the filtering box to vibrate, thereby performing the first-level anti-blocking treatment on the filtering box. During the up and down movement of the filtering box, the anti-blocking frame will be driven to move up and down. Since the link frame is hinged to the anti-blocking frame, for example, when the anti-blocking frame moves upward, the two link frames on both sides will respectively push the two anti-blocking frames closer to each other. Similarly, during the up and down movement of the anti-blocking frame, under the action of the link frame, the anti-blocking frame slides left and right in the filtering box, thereby performing the second-level anti-blocking treatment on the filtering box. Through the setting of the torsion spring, the torsion spring always applies a torsion force to the link frame, so that the link frame applies a downward component force to the anti-blocking frame, thereby making the anti-blocking frame closely adhere to the bottom of the inner wall of the filtering box. At the same time, when the link frame reciprocates, it will drive the fixed rod to reciprocate. Then, under the cooperation of the fixed rod and the sliding frame, the fixed rod drives the sliding frame to reciprocate up and down, thereby driving the support plate and the dredging frame to reciprocate up and down, thereby dredging and preventing blockage of the feeding port of the crushing box. At the same time, during the up and down reciprocating movement of the positioning frame, it will drive the driving frame to reciprocate up and down, thereby driving the dredging rod to reciprocate up and down, thereby dredging the material in the treatment box to avoid blockage of the material at the feeding port of the crushing box and ensuring smooth feeding of the feeding assembly.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The present invention adopts the structural optimization and innovative design of the high-temperature melting device, which greatly improves the melting effect of hazardous waste. In the feeding link, the screw conveying component precisely controls the conveying amount of hazardous waste, ensuring that the material enters the crushing box evenly and quantitatively, effectively avoiding the problem of insufficient melting caused by uneven feeding. The design of the opposite rotation of the crushing rollers can efficiently crush the hazardous waste to an appropriate particle size, providing a good foundation for subsequent high-temperature melting, enabling the material to be fully heated and evenly mixed in the melting component, significantly improving the melting efficiency and quality, ensuring that harmful substances can be more effectively fixed in the glass body, and realizing the harmless treatment of hazardous waste. By the ingenious cooperation of the filter box and the positioning frame, when the second motor drives the adjusting rod to rotate, the positioning frame moves up and down reciprocally, not only realizing the vibration of the filter box and performing the first-level anti-blocking treatment on the filter box; at the same time, the anti-blocking frame slides left and right in the filter box under the action of the connecting rod frame and the torsion spring to complete the second-level anti-blocking treatment, effectively preventing material blockage and ensuring smooth feeding. In addition, the cooperation of the fixed rod and the sliding frame drives the support plate and the dredging frame to move up and down reciprocally to dredge and prevent blockage at the feeding port of the crushing box; the positioning frame drives the driving frame and the dredging rod to dredge the material in the treatment box to avoid material blockage at the feeding port, comprehensively ensuring the efficient operation of the feeding component, reducing the equipment maintenance cost, improving the overall stability and reliability of the device, enabling the operator to use the device to process hazardous waste more conveniently and efficiently, and the device has the advantages of good melting effect, good feeding effect and good anti-blocking effect.

[0017] 2. Through the settings of the driving frame, the sliding groove and the dredging rod, when the positioning frame moves up and down reciprocally, it will drive the driving frame to slide up and down, and then drive the dredging rod to move up and down reciprocally, thereby dredging and preventing blockage of the material in the treatment box and avoiding material blockage at the feeding port of the crushing box.

Both the front side and the rear side of the inner wall of the support frame 9 are fixedly connected with fixing columns 12. A connecting rod frame 13 is rotatably connected inside the fixing columns 12. A torsion spring 15 is fixedly connected to the surface of the connecting rod frame 13. One end of the torsion spring 15 away from the connecting rod frame 13 is fixedly connected with the fixing column 12. Anti-blocking frames 14 are arranged on both sides of the bottom of the inner wall of the filter box 11. The anti-blocking frames 14 are hinged with the connecting rod frame 13. Fixing rods 16 are fixedly connected to both the front and the back of the connecting rod frame 13. Sleeves 17 are fixedly connected to both sides on the front and the back of the crushing box 3. A movable column 18 is slidably connected inside the sleeves 17. The bottom of the movable column 18 is fixedly connected with a sliding frame 19. The sliding frame 19 is slidably connected with the fixing rods 16. Support plates 20 are fixedly connected to both sides of the top of the sliding frame 19. A dredging frame 21 is fixedly connected to the top of the support plates 20.

[0028] Reference Figure 2 , a driving frame 22 is fixedly connected to the back of the positioning frame 10. A sliding groove is arranged on the back of the crushing box 3, and the driving frame 22 is slidably connected with the sliding groove. A dredging rod 23 is fixedly connected to the surface of the driving frame 22. The dredging rod 23 is slidably connected with the treatment box 5.

[0029] As a technical optimization scheme of the present invention, through the settings of the driving frame 22, the sliding groove and the dredging rod 23, when the positioning frame 10 moves up and down reciprocally, it will drive the driving frame 22 to slide up and down, and then drive the dredging rod 23 to move up and down reciprocally, so as to dredge and prevent blockage of the materials in the treatment box 5, and avoid the materials from being blocked at the feeding port of the crushing box 3.

[0030] Reference Figure 2 , guide plates 24 are fixedly connected to both sides of the inner wall of the crushing box 3.

[0031] As a technical optimization solution of the present invention, through the setting of the diversion plate 24, the materials falling from the treatment box 5 can be guided, so that the materials fall between the two crushing rollers 7, thereby improving the crushing effect of the device.

[0032] Reference Figure 2 , a collecting hopper 28 is fixedly connected to the surface of the support frame 9, a guiding pipe 29 is communicated with the bottom of the collecting hopper 28, and the discharge port of the guiding pipe 29 extends above the feed port of the melting assembly 1.

[0033] As a technical optimization solution of the present invention, through the setting of the collecting hopper 28 and the guiding pipe 29, the collecting hopper 28 can collect the materials falling from the filtering box 11, and then convey the materials to the feed port of the melting assembly 1 through the guiding pipe 29, thereby feeding the melting assembly 1.

[0034] Reference Figure 4 , limiting blocks 32 are fixedly connected to the front side and the rear side of the inner wall of the positioning frame 10, the limiting blocks 32 are in contact with the filtering box 11, mounting blocks 31 are fixedly connected to both sides of the front surface of the filtering box 11, and the mounting blocks 31 and the positioning frame 10 are fixedly connected by bolts.

[0035] As a technical optimization solution of the present invention, through the setting of the limiting blocks 32, the filtering box 11 can be supported. Through the setting of the mounting blocks 31, the mounting blocks 31 can be installed with the positioning frame 10 by bolts, thereby limiting the filtering box 11 to prevent the filtering box 11 from moving back and forth when moving up and down reciprocally. When the operator needs to disassemble the filtering box 11, the operator disassembles the bolts and then pulls the filtering box 11 forward. Before pulling out the filtering box 11, the operator needs to adjust the rotation of the connecting rod frame 13, so that the anti-blocking frame 14 rotates upward, thereby preventing the anti-blocking frame 14 from interfering with the filtering box 11 during the front-back movement, thereby taking out and cleaning the unqualified materials in the filtering box 11. The cross section of the adjusting rod 26 is elliptical, and the surface of the adjusting rod 26 is smooth, so no materials will accumulate on the surface of the adjusting rod 26.

[0036] Reference Figure 1 , protective frames 30 are fixedly connected to the front surface and the rear surface of the crushing box 3, the number of the protective frames 30 is several, and the protective frames 30 are evenly distributed on the surface of the crushing box 3.

[0037] As a technical optimization solution of the present invention, through the setting of the protective frames 30, it can play a role in anti-collision to a certain extent, thereby improving the protection effect of the device.

[0038] Reference Figure 2, a bearing is fixedly connected inside the support block 25, and the outer ring of the bearing is fixedly connected to the support block 25, and the inner ring of the bearing is fixedly connected to the adjusting rod 26.

[0039] As a technical optimization scheme of the present invention, through the setting of the bearing, the frictional force between the support block 25 and the adjusting rod 26 can be reduced, thereby facilitating the rotation of the adjusting rod 26.

[0040] Reference Figure 1 , a high-temperature melting device for hazardous waste and its use method, comprising the following steps:

[0041] S1: During operation, the hazardous waste is conveyed to the treatment tank 5 through the screw conveying assembly 6. The principle of the screw conveying assembly 6 is that the motor drives the screw conveyor rod to rotate, thereby conveying the hazardous waste evenly and relatively quantitatively into the crushing tank 3. On the one hand, the purpose of quantitative feeding is achieved, and on the other hand, clogging can be avoided by uniform feeding. The hazardous waste enters the crushing tank 3 through the treatment tank 5. The first motor 8 is started to drive the crushing roller 7 to rotate. The two crushing rollers 7 rotate towards each other to crush the hazardous waste. The crushed material falls into the filter tank 11 and is filtered through the filter tank 11. The qualified material enters the feed port of the melting assembly 1 through the aggregate hopper 28 and the guide pipe 29 on the surface of the support frame 9.

[0042] S2: During the crushing process of the crushing roller 7, the second motor 27 drives the adjusting rod 26 to rotate. Since the cross-section of the adjusting rod 26 is elliptical, when the adjusting rod 26 rotates, it can drive the positioning frame 10 to reciprocate up and down in the sliding groove, thereby driving the filter box 11 to reciprocate up and down, further driving the filter box 11 to vibrate, and then performing the first-level anti-blocking treatment on the filter box 11. During the up and down movement of the filter box 11, it will drive the anti-blocking frame 14 to move up and down. Since the connecting rod frame 13 is hinged to the anti-blocking frame 14, for example, when the anti-blocking frame 14 moves upward, the connecting rod frames 13 on both sides will respectively push the anti-blocking frames 14 on both sides to approach each other. Similarly, during the up and down movement of the anti-blocking frame 14, under the action of the connecting rod frame 13, the anti-blocking frame 14 slides left and right in the filter box 11, and then performs the second-level anti-blocking treatment on the filter box 11. Through the setting of the torsion spring 15, the torsion spring 15 always exerts a torsion force on the connecting rod frame 13, so that the connecting rod frame 13 exerts a downward component force on the anti-blocking frame 14, thereby making the anti-blocking frame 14 closely adhere to the bottom of the inner wall of the filter box 11. At the same time, when the connecting rod frame 13 reciprocates, it will drive the fixed rod 16 to reciprocate. Then, under the cooperation of the fixed rod 16 and the sliding frame 19, the fixed rod 16 drives the sliding frame 19 to reciprocate up and down, further driving the support plate 20 and the dredging frame 21 to reciprocate up and down, and then dredging and preventing blockage of the feeding port of the crushing box 3. At the same time, during the up and down reciprocating movement of the positioning frame 10, it will drive the driving frame 22 to reciprocate up and down, further driving the dredging rod 23 to reciprocate up and down, and then dredging the materials in the processing box 5, avoiding the blockage of the materials at the feeding port of the crushing box 3, and ensuring the smooth feeding of the feeding assembly 2.

[0043] Working principle and usage process of the present invention: During use, the melting component 1, as the core part, mainly consists of a high-temperature resistant furnace, a heating system, a stirring mechanism, and a temperature control system. The high-temperature resistant furnace is made of special high-temperature and corrosion-resistant materials, which can withstand extremely high temperatures and ensure that the internal materials will not damage the furnace wall in a high-temperature environment. Its internal space is cylindrical, with a feeding port at the top, which is docked with the discharging end of the feeding component 2, and a discharging port at the bottom for discharging the melted materials. The heating system surrounds the outside of the furnace and consists of multiple high-power heating elements. These heating elements can be resistance heating wires or gas burners, etc. Through different energy supply methods, they provide stable and high-intensity heat for the furnace to ensure that the internal temperature of the furnace can quickly rise and be maintained in the high-temperature range required for the melting of hazardous waste, generally reaching 1200°C - 1600°C. The stirring mechanism is installed inside the furnace and consists of a stirring motor, a stirring shaft, and stirring blades. The stirring motor is located at the top of the furnace and is connected to the inside of the furnace through a sealing device to prevent heat dissipation and leakage of harmful gases. The stirring shaft vertically penetrates the top of the furnace and extends to the bottom of the furnace, and multiple groups of stirring blades with different shapes and angles are fixed on the shaft. These blades can rotate at high speed under the drive of the stirring motor to fully stir the hazardous waste in the furnace. The temperature control system includes a temperature sensor, a controller, and a display panel. The temperature sensor is installed at different positions inside the furnace to continuously monitor the temperature inside the furnace and transmit the data to the controller. The controller automatically adjusts the power of the heating system according to the preset temperature value to keep the temperature inside the furnace stable. The display panel is installed on the equipment operation platform to facilitate the operator to intuitively understand the temperature situation inside the furnace.

[0044] When the hazardous waste that has been crushed and filtered by the feeding component 2 enters the high-temperature resistant furnace through the feeding port, the heating system starts to work. The heating elements quickly heat up and transfer the heat to the furnace wall, thereby rapidly increasing the internal temperature of the furnace. During the process of gradually increasing the temperature, the stirring mechanism starts to operate. The stirring motor drives the stirring shaft and blades to rotate to stir the hazardous waste. The function of stirring is on the one hand to make the materials heat more evenly, avoiding local overheating or overcooling and improving the melting efficiency; on the other hand, it can fully mix different types of hazardous waste, promote the progress of chemical reactions, and make harmful substances more effectively fixed in the glass body. The temperature sensor continuously monitors the temperature inside the furnace and feeds back the data to the controller. If the temperature is lower than the preset value, the controller will increase the power of the heating system to make the heating elements generate more heat; conversely, if the temperature is higher than the preset value, the controller will reduce the power of the heating system to ensure that the temperature is always stable within the optimal melting temperature range of the hazardous waste. When the materials are completely melted into a uniform liquid state, they are discharged through the discharging port at the bottom to complete the entire melting process. The above-mentioned melting component 1 is a common existing technology and is common knowledge in this field, so it will not be elaborated in detail in this application.

[0045] During operation, hazardous waste is conveyed to the treatment tank 5 through the screw conveyor assembly 6 and then enters the crushing tank 3. The first motor 8 is started to drive the crushing roller 7 to rotate, crushing the hazardous waste. The crushed material is filtered through the filter tank 11, and the qualified material enters the feed port of the melting assembly 1 through the aggregate hopper 28 and the guide pipe 29 on the surface of the support frame 9. The second motor 27 drives the adjusting rod 26 to rotate. Since the cross-section of the adjusting rod 26 is oval, it can push the positioning frame 10 to move up and down in the chute during rotation, thereby driving the filter tank 11 to move up and down to achieve the filtering adjustment of materials with different particle sizes. During the filtering process, the connecting rod frame 13 drives the anti-blocking frame 14 to slide in the filter tank 11 under the action of the torsion spring 15 to prevent the material from blocking the filter tank 11. At the same time, when the positioning frame 10 moves up and down, the sliding frame 19 and the dredging frame 21 are driven to move up and down through the fixing rod 16 to further dredge the filter tank 11 to ensure smooth filtering. The principle of the above screw conveyor assembly 6 is similar to that of a screw conveyor. It drives the screw conveyor rod to rotate through a motor, thereby quantitatively and uniformly conveying the material, and then achieving the purpose of uniform and quantitative feeding. The above screw conveyor assembly 6 is a common existing technology and is well-known to those skilled in the art, so it will not be described in detail in this application.

8. The usage method of a high-temperature melting device for hazardous waste according to claim 1, characterized in that: Comprising the following steps: S1: During operation, hazardous waste is conveyed to the treatment box (5) through the screw conveying assembly (6). The principle of the screw conveying assembly (6) is that the motor drives the screw conveyor rod to rotate, so as to convey the hazardous waste evenly and relatively quantitatively into the crushing box (3). On the one hand, the purpose of quantitative feeding is achieved. On the other hand, blockage can be avoided by uniform feeding. The hazardous waste enters the crushing box (3) through the treatment box (5). The first motor (8) is started to drive the crushing roller (7) to rotate. The two crushing rollers (7) rotate towards each other to crush the hazardous waste. The crushed material falls into the filter box (11) and is filtered by the filter box (11). The qualified material enters the feed port of the melting assembly (1) through the hopper (28) on the surface of the support frame (9) and the guide pipe (29). S2: During the crushing process of the crushing roller (7), the second motor (27) drives the adjusting rod (26) to rotate. Since the cross-section of the adjusting rod (26) is oval, when the adjusting rod (26) rotates, it can drive the positioning frame (10) to reciprocate up and down in the chute, thereby driving the filter box (11) to reciprocate up and down, and then driving the filter box (11) to vibrate, thereby performing the first-stage anti-blocking treatment on the filter box (11). During the up and down movement of the filter box (11), it will drive the anti-blocking frame (14) to move up and down. Since the connecting rod frame (13) is hinged to the anti-blocking frame (14), for example, when the anti-blocking frame (14) moves upward, the connecting rod frames (13) on both sides will respectively push the anti-blocking frames (14) on both sides to approach each other. Similarly, during the up and down movement of the anti-blocking frame (14), under the action of the connecting rod frame (13), the anti-blocking frame (14) slides left and right in the filter box (11), thereby performing the second-stage anti-blocking treatment on the filter box (11). Through the setting of the torsion spring (15), the torsion spring (15) always applies a torsion force to the connecting rod frame (13), so that the connecting rod frame (13) applies a downward component force to the anti-blocking frame (14), thereby making the anti-blocking frame (14) closely adhere to the bottom of the inner wall of the filter box (11). At the same time, when the connecting rod frame (13) reciprocates, it will drive the fixed rod (16) to reciprocate. Then, under the cooperation of the fixed rod (16) and the sliding frame (19), the fixed rod (16) drives the sliding frame (19) to reciprocate up and down, thereby driving the support plate (20) and the dredging frame (21) to reciprocate up and down, thereby dredging and preventing blockage of the feeding port of the crushing box (3). At the same time, during the up and down reciprocating movement of the positioning frame (10), it will drive the driving frame (22) to reciprocate up and down, thereby driving the dredging rod (23) to reciprocate up and down, thereby dredging the materials in the processing box (5), preventing the materials from blocking at the feeding port of the crushing box (3), and ensuring the smooth feeding of the feeding assembly (2).
