Description

Technical Field

[0001] The invention belongs to the field of sludge drying, and relates to smoldering treatment of copper-containing sludge, in particular to flameless combustion treatment equipment for copper-containing sludge and a continuous feeding method thereof. Background Art

[0002] Traditional sludge smoldering furnaces usually use a gate valve or a star-shaped ash discharge valve for intermittent feeding. When feeding, open the valve to pour the sludge into the furnace, and then close the valve to seal the feed port. During the feeding process, smoke emerges from the gap of the gate valve, and the sealing effect is poor; the feeding is discontinuous and the processing efficiency is low. Due to the physical properties of the sludge, the sludge is easy to compact and bridge in the star-shaped ash discharge valve, resulting in poor feeding; the feeding is uneven, and the material layer height in the furnace is uneven, resulting in local overheating or overcooling, affecting the smoldering effect and the stability of the entire equipment operation.

[0003] The above intermittent feeding method results in discontinuous feeding process, which affects the processing efficiency and cannot meet the large-scale processing needs. Discontinuous feeding may also cause temperature fluctuations in the furnace, affecting the smoldering effect. During the feeding process, the smoke in the furnace is easy to emerge from the feeding port, which will also cause environmental pollution and waste of energy. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in order to solve the problems of unstable feeding, flue gas leakage and sludge compaction and bridging in traditional sludge smoldering furnaces in the above-mentioned background technology, a flameless combustion treatment equipment for copper-containing sludge is provided. By arranging components such as a telescopic rotating unit, a material dividing sealing cone and a rotary material equalizer, the technical problems of uneven feeding and unstable operation of the smoldering furnace are solved, thereby achieving the purpose of uniform and stable feeding of the smoldering furnace; at the same time, the technical problem of flue gas leakage during the feeding process of the traditional smoldering furnace is solved, thereby achieving the purpose of continuous and stable operation of the smoldering furnace.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a flameless combustion treatment device for copper-containing sludge, comprising a smoldering furnace, a continuous feeding mechanism is provided on the top of the smoldering furnace, and the continuous feeding mechanism comprises: A mounting frame, which is arranged at the feed inlet on the top of the smoldering furnace; A sludge storage hopper is installed inside the middle section of the mounting frame, the top of the sludge storage hopper is provided with a feed inlet, and the lower end thereof is open, and the opening is butted against the feed inlet; A telescopic rotating unit is mounted on the top of the mounting frame and extends through the sludge storage hopper into the smoldering furnace, wherein the lower end of the telescopic rotating unit is sequentially connected with a material distribution sealing cone and a rotary material distributor; When the telescopic and rotating unit ascends, the material distributing and sealing cone can seal the feeding port, and at the same time drive the sludge in the sludge storage hopper to ascend to prevent the leakage of smoldering flue gas. When the telescopic and rotating unit descends, the material distributing and sealing cone can evenly discharge materials and can break and level the sludge at the feeding port by the rotating material distributor.

[0006] Through the design of the continuous feeding mechanism, the continuous and stable feeding of sludge is realized, and the treatment efficiency is significantly improved. When ascending, the material distributing and sealing cone seals the feeding port to prevent the leakage of flue gas, improving the environmental protection performance of the equipment. When descending, the rotating material distributor breaks and levels the sludge to ensure uniform filling of materials in the smoldering furnace and prevent the occurrence of too high or too low local temperature, improving the smoldering effect.

[0007] According to an embodiment of the present invention, a plurality of anti-arching pieces are arranged on a section of the telescopic and rotating unit in the sludge storage hopper, which are evenly distributed in a staggered manner up and down. The anti-arching pieces stir the sludge in the sludge storage hopper when the telescopic and rotating unit ascends or descends.

[0008] The anti-arching pieces stir the sludge when the telescopic and rotating unit ascends or descends to prevent the sludge from caking and bridging and ensure smooth feeding. Through the stirring effect, manual intervention is reduced, and the automation level and operation efficiency of the equipment are improved.

[0009] According to an embodiment of the present invention, the included angle between two adjacent anti-arching pieces is 120°; the maximum outer diameters of the plurality of anti-arching pieces decrease successively from top to bottom, and when the material distributing and sealing cone seals the feeding port, the gaps between the outer side walls of the plurality of anti-arching pieces and the inner side wall of the sludge storage hopper are the same.

[0010] The anti-arching pieces are distributed in a staggered manner with an included angle of 120° to ensure uniform stirring effect and prevent the sludge from forming dead corners in the storage hopper. The maximum outer diameters of the anti-arching pieces decrease successively from top to bottom and the gaps with the inner side wall of the sludge storage hopper are the same, ensuring the comprehensiveness and consistency of stirring.

[0011] According to an embodiment of the present invention, the telescopic and rotating unit includes a telescopic cylinder, a connecting sleeve, a rotating assembly and a connecting rod. The telescopic cylinder is installed at the top of the mounting frame, and its piston rod passes through the top wall and is connected to the connecting sleeve. One end of the connecting rod is connected to the connecting sleeve, and a rotating assembly is installed on the connecting sleeve. The rotating assembly is composed of a rotating motor, a connecting frame, a driving gear and a driven gear. The connecting frame is fixed on the inner top surface of the mounting frame and sleeved on the connecting sleeve. The driven gear is fixed on the connecting sleeve, and the rotating motor is installed at one end of the connecting frame, and a driving gear meshing with the driven gear is installed on its output shaft.

[0012] The structural design of the telescopic and rotating unit simplifies the equipment and improves the reliability and maintenance convenience. Through the cooperation of the telescopic cylinder and the rotating assembly, the precise lifting and rotation of the material distributing and sealing cone are realized to ensure the continuity and uniformity of feeding.

[0013] According to an embodiment of the present invention, the connecting rod is coaxial with the central axis of the sludge storage hopper, and a seal is provided at the connection between the two.

[0014] The connecting rod is coaxial with the central axis of the sludge storage hopper and is provided with a seal to ensure the sealing performance during the feeding process and prevent flue gas from leaking. The seal reduces friction and wear during the operation of the equipment and extends the service life of the equipment.

[0015] According to an embodiment of the present invention, a level gauge is provided at the upper part of the sludge storage hopper. The level gauge is connected to the controller of the feeding control system. The feeding port is connected to an external feeding system, and the external feeding system is connected to the feeding control system.

[0016] The level gauge monitors the sludge height in real time to ensure that a high level is always maintained in the sludge storage hopper, achieving continuous feeding and a sealing effect. The external feeding system is linked with the feeding control system and automatically starts and stops according to the feedback of the level gauge, improving the automation level of the equipment.

[0017] According to an embodiment of the present invention, the sludge height in the sludge storage hopper is 73% - 85% of the total height of the sludge storage hopper.

[0018] The sludge height in the sludge storage hopper is 73% - 85%, forming an effective sealing layer to prevent flue gas from leaking. The high level ensures that there is always enough sludge supply in the sludge storage hopper to achieve continuous feeding.

[0019] According to an embodiment of the present invention, the rotary material distributor has a number of uniformly distributed scraping plates. The scraping plates have an inclination angle with the horizontal plane, and a bent portion that bends upward is provided at the outer end of the scraping plate.

[0020] The scraping plates of the rotary material distributor have an inclination angle with the horizontal plane and are provided with a bent portion that bends upward to ensure that the sludge is evenly distributed in the smoldering furnace. The bent portion prevents the sludge from splashing during the cloth feeding process, improving the cloth feeding effect and the stability of the equipment operation.

[0021] A continuous feeding method for the copper-containing sludge flameless combustion treatment equipment in the above solution is also provided, specifically as follows: Starting feeding: After the feeding control system receives the feeding instruction, it starts the telescopic cylinder and the rotary motor. The telescopic cylinder drives the connecting rod to descend at a stroke speed of 10 - 20 nm / s. The material distribution and sealing cone follows the connecting rod to descend and opens the feeding port, and the sludge starts to fall. Continuous feeding: During the descent of the material distribution and sealing cone, the sludge is evenly distributed to ensure that the sludge enters the smoldering furnace at a stable flow rate. At the same time, the rotating motor drives the connecting rod to rotate at a rotational speed of 5 - 10 rmp. The arch-breaking pieces on the connecting rod stir the sludge in the sludge storage hopper, and the stirring frequency of the arch-breaking pieces is synchronized with the lifting frequency of the telescopic rotating unit to prevent the sludge from caking and bridging. The material distribution and sealing cone and the rotating material distributor rotate synchronously. The rotating material distributor crushes and flattens the sludge to ensure uniform filling of the material in the smoldering furnace. The level gauge monitors the sludge height in real time at a frequency of 1 time per second. When the sludge height is lower than 73% of the sludge storage hopper, the feeding control system activates the external feeding system to supplement the sludge to 82% of the sludge storage hopper. The feeding speed of the external feeding system is 0.5 - 1.0 m 3 / h; Feeding end: After the feeding control system receives the stop instruction, the telescopic cylinder drives the connecting rod to rise. The material distribution and sealing cone closes the feeding port of the smoldering furnace, driving the sludge liquid level in the sludge storage hopper to rise to 85% of the sludge storage hopper, stopping the sludge from falling, and preparing for the next feeding.

[0022] Continuous and stable feeding is achieved through the automatic control system, ensuring the tightness and uniformity of the feeding process. The stirring frequency of the arch-breaking pieces is synchronized with the lifting frequency of the telescopic rotating unit to prevent sludge caking and bridging and improve the feeding efficiency. The interlocking control of the level gauge and the external feeding system ensures that a high material level is always maintained in the sludge storage hopper, achieving continuous feeding and sealing effect.

[0023] According to an embodiment of the method of the present invention, during continuous feeding, the rotating motor performs forward and reverse rotations with a small stroke at a frequency of 10 times per minute. This setting improves the stirring effect, further prevents sludge caking and bridging, and ensures the uniformity of material dropping.

[0024] Advantages of the present invention: (1) Through the combination of the continuous feeding mechanism and the automatic control system, continuous and stable feeding of sludge is achieved, significantly improving the treatment efficiency and meeting the large-scale treatment requirements.

[0025] (2) The design of the material distribution and sealing cone and the high sludge level seal ensures the tightness during the feeding process, effectively preventing flue gas leakage, reducing environmental pollution and energy waste.

[0026] (3) The integrated stirring structure with arch-breaking pieces can prevent sludge from caking and bridging in the storage hopper, ensuring smooth sludge dropping, reducing manual intervention and maintenance costs.

[0027] (4) The combination of the rotating material distributor and the material distribution and sealing cone ensures uniform distribution of sludge in the smoldering furnace, improving the smoldering effect, preventing local overheating or overcooling, and ensuring the stability of equipment operation and treatment effect.

[0028] (5)Design of the level gauge and automatic control system to achieve automatic control and optimization of the feeding process, improve the automation level of the equipment, reduce manual operation, ensure the continuity and stability of the feeding process, and further optimize the operation efficiency of the equipment.

[0029] (6)Simplified design of the seal and structure, reducing friction and wear during equipment operation, extending the service life of the equipment, and reducing maintenance costs.

[0030] (6)Design of efficient sealing and uniform material distribution, reducing flue gas leakage and material splashing, improving the environmental protection performance of the equipment, and meeting environmental protection requirements.

[0031] The copper-containing sludge flameless combustion treatment equipment and its continuous feeding method of the present invention have significant advantages in improving treatment efficiency, enhancing sealing performance, preventing sludge caking and bridging, uniform feeding and material distribution, automatic control and optimization, extending the service life of the equipment, and improving environmental protection performance; not only improving the treatment efficiency and operation stability of the equipment, but also significantly enhancing the environmental protection performance and automation level of the equipment.

[0042] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present invention in a schematic way, so they only show the components related to the present invention.

[0043] Embodiment 1 As Figure 1 and Figure 2 shown, the flameless combustion treatment equipment for copper-containing sludge in this embodiment includes a smoldering furnace 1. A continuous feeding mechanism is provided at the top of the smoldering furnace 1. The continuous feeding mechanism includes a mounting frame 2, a sludge storage hopper 3 and a telescopic and rotating unit 4. The mounting frame is arranged at the feed inlet 11 at the top of the smoldering furnace 1, specifically at the exact center of the top of the smoldering furnace 1. The sludge storage hopper 3 is a conical structure with a large top and a small bottom, and it is installed inside the middle section of the mounting frame 2. The top of the sludge storage hopper 3 has an inlet 31, and the inlet 31 is arranged close to the edge of the sludge storage hopper 3. In this way, it will not interfere with the telescopic and rotating unit 4. The lower end of the sludge storage hopper 3 is open, and this opening is docked with the feed inlet 11. The telescopic and rotating unit 4 is installed on the top of the mounting frame 2 and passes through the sludge storage hopper 3 and extends into the smoldering furnace 1. The lower end of the telescopic and rotating unit 4 is successively connected with a material distributing and sealing cone 5 and a rotating material equalizer 6. When the telescopic and rotating unit 4 rises, the material distributing and sealing cone 5 can seal the feed inlet 11, and at the same time drive the sludge in the sludge storage hopper 3 to rise to prevent the leakage of smoldering flue gas; when the telescopic and rotating unit 4 descends, the material distributing and sealing cone 5 can evenly discharge materials and can break and level the sludge at the feed inlet 11 by the rotating material equalizer 6.

[0044] As Figure 3 shown, the telescopic and rotating unit 4 includes a telescopic cylinder 41, a connecting sleeve 42, a rotating assembly 43 and a connecting rod 44. The telescopic cylinder 41 is installed on the top of the mounting frame 2, and its piston rod passes through the top wall and is connected with the connecting sleeve 42. One end of the connecting rod 44 is connected with the connecting sleeve 42, and the rotating assembly 43 is installed on the connecting sleeve 42. Specifically, the rotating assembly 43 is composed of a rotating motor 431, a connecting frame 432, a driving gear 433 and a driven gear 434. The connecting frame 432 is fixed on the inner top surface of the mounting frame 2 and sleeved on the connecting sleeve 42. The driven gear 434 is fixed on the connecting sleeve 42. The rotating motor 431 is installed at one end of the connecting frame 432, and a driving gear 433 meshing with the driven gear 434 is installed on its output shaft.

[0045] As shown Figure 4 in the figure, three arch-breaking pieces 7 are arranged on a connecting rod 44 within a sludge storage hopper 3 at upper and lower staggered and evenly distributed positions. The three arch-breaking pieces 7 stir the sludge within the sludge storage hopper 3 when the telescopic and rotating unit 4 ascends or descends. Specifically, the included angle between two adjacent arch-breaking pieces 7 is 120°; the maximum outer diameters of the three arch-breaking pieces 7 decrease successively from top to bottom, and when the material distribution and sealing cone 5 seals the feed inlet 11, the clearances between the outer side walls of the three arch-breaking pieces 7 and the inner side wall of the sludge storage hopper 3 are the same. The connecting rod 44 is coaxial with the central axis of the sludge storage hopper 3, and a seal 45 is provided at the connection between the two.

[0046] As shown Figure 5 in the figure, a level gauge 8 is provided at the upper part of the sludge storage hopper 3. The level gauge 8 is connected to the controller of the feed control system. The feed inlet 31 is connected to an external feeding system, and the external feeding system is connected to the feed control system. The height of the sludge within the sludge storage hopper 3 is 73% - 85% of the total height of the sludge storage hopper 3.

[0047] As shown Figure 6 in the figure, the material distribution and sealing cone 5 is a conical structure with a smaller upper part and a larger lower part, and the inclination angle of its side wall is less than 60 degrees, which helps the sludge to slide smoothly under the action of gravity and avoid blockage. Since the sludge slides from the surface of the material distribution and sealing cone 5, the surface roughness thereof is about Ra1.6 - 3.2 microns, which can not only reduce the friction between the sludge and the conical surface to ensure smooth sliding, but also avoid slipping or adhesion caused by the surface being too smooth.

[0048] As shown Figure 7 in the figure, the rotating material leveling device 6 has four evenly distributed scraping plates 61. The scraping plates 61 have an inclination angle with the horizontal plane, and the angle of the inclination is 15° - 30°, ensuring that the sludge is evenly paved. A bent portion that bends upward is provided at the outer end of the scraping plate 61, and the height of the bent portion is 50 - 100 mm, which can prevent the sludge from splashing during the falling process.

[0049] In the copper-containing sludge flameless combustion treatment equipment of this embodiment, the material distribution and sealing cone 5 can evenly discharge materials when the telescopic and rotating unit 4 descends. At the same time, the rotating material leveling device 6 crushes and levels the sludge, ensuring uniform filling of materials within the smoldering furnace 1; avoiding material accumulation or uneven distribution, and improving the smoldering efficiency and the stability of equipment operation. The three arch-breaking pieces 7 on the connecting rod 44 stir the sludge when the telescopic and rotating unit 4 ascends or descends, preventing the sludge from caking or bridging within the sludge storage hopper 3, and further optimizing the uniformity of feeding. The included angle between adjacent arch-breaking pieces 7 is 120°, the maximum outer diameters decrease successively from top to bottom, and the clearances with the inner side wall of the sludge storage hopper 3 are the same, ensuring that the arch-breaking pieces 7 can efficiently prevent sludge accumulation during the stirring process and avoid interference with the inner wall of the sludge storage hopper 3.

[0050] When the telescopic and rotating unit 4 rises, the material distribution and sealing cone 5 can tightly seal the feed inlet 11 of the smoldering furnace 1, while driving the sludge in the sludge storage hopper 3 to rise, preventing the smoldering flue gas from leaking out of the feed inlet 11; effectively improving the sealing performance of the equipment, reducing the risk of flue gas leakage, and enhancing the safety and environmental protection performance of the equipment. The connecting rod 44 is coaxial with the central axis of the sludge storage hopper 3, and a seal 45 is provided at the connection, further ensuring the sealing performance during the operation of the equipment and preventing material leakage or external impurities from entering. The sludge storage hopper 3 adopts a conical structure with a larger upper part and a smaller lower part, and the feed inlet 31 is arranged close to the edge, avoiding interference with the telescopic and rotating unit 4 and optimizing the overall layout of the equipment. Through the coordinated control of the rotating motor 431 and the telescopic cylinder 41, the equipment can achieve precise telescopic and rotating movements, ensuring the continuity and uniformity of the feeding process. The rotating assembly 43 consists of a rotating motor 431, a connecting frame 432, a driving gear 433, and a driven gear 434, achieving efficient and stable rotating movements through gear transmission; not only improving the mechanical transmission efficiency, but also reducing the noise and energy consumption during the operation of the equipment.

[0051] A level gauge 8 is provided at the upper part of the sludge storage hopper 3. The level gauge 8 is connected to the controller of the feeding control system and can real-time monitor the sludge height. The sludge height in the sludge storage hopper 3 is controlled at 73% - 85% of the total height. When the level is lower than the set value, the external feeding system is automatically started to supplement the sludge to the set height; not only ensuring a high level to prevent flue gas leakage, but also optimizing the operation efficiency of the equipment and reducing equipment failures caused by too high or too low levels. This automated design reduces manual intervention and improves the stability and efficiency of equipment operation. The rotating and leveling device 6 has four evenly distributed scraping plates 61. The scraping plates 61 have an inclination angle of 15° - 30° with the horizontal plane, and the outer ends are provided with upwardly bent portions, preventing the splashing of sludge during the falling process, reducing the material accumulation inside the equipment, and reducing the maintenance cost of the equipment; not only improving the uniformity of material distribution, but also reducing the wear of the equipment and extending the service life.

[0052] Embodiment 2 A method for continuous feeding using the copper-containing sludge flameless combustion treatment equipment of Embodiment 1 is as follows: Starting feeding: After the feeding control system receives the feeding instruction, it starts the telescopic cylinder 41 and the rotating motor 431. The telescopic cylinder 41 drives the connecting rod 44 to descend at a stroke speed of 10 - 20 nm / s, and the material distribution and sealing cone 5 follows the connecting rod 44 to descend and open the feed inlet 11, and the sludge starts to fall, as Figure 1 shown Continuous feeding: During the descent of the material distribution and sealing cone 5, the sludge is evenly distributed to ensure that the sludge enters the smoldering furnace 1 at a stable flow rate. At the same time, the rotary motor 431 drives the connecting rod 44 to rotate at a rotational speed of 5 - 10 rmp. The arch-breaking pieces 7 on the connecting rod 44 stir the sludge in the sludge storage hopper 3, and the stirring frequency of the arch-breaking pieces 7 is synchronized with the lifting frequency of the telescopic and rotating unit 4 to prevent sludge caking and bridging. The material distribution and sealing cone 5 and the rotary material distributor 6 rotate synchronously. The rotary material distributor 6 crushes and levels the sludge to ensure uniform filling of the material in the smoldering furnace 1. The level gauge 8 monitors the sludge height in real time at a frequency of 1 time per second. When the sludge height is lower than 73% of the sludge storage hopper 3, the feeding control system activates the external feeding system to supplement the sludge to 82% of the sludge storage hopper. The feeding speed of the external feeding system is 0.5 - 1.0 m 3 / h; Feeding end: After receiving the stop instruction, the telescopic cylinder 41 drives the connecting rod 44 to rise. The material distribution and sealing cone 5 closes the feeding port 11 of the smoldering furnace 1, driving the sludge liquid level in the sludge storage hopper 3 to rise to 85% of the sludge storage hopper 3, stopping the sludge from falling, and preparing for the next feeding, as Figure 2 shown.

[0053] During continuous feeding, the rotary motor 431 performs forward and reverse rotations with small strokes at a frequency of 10 times per minute.

[0054] In the method of this embodiment, the telescopic cylinder 41 controls the connecting rod 44 to descend at a speed of 10 - 20 mm / s. The material distribution and sealing cone 5 can evenly distribute the sludge, ensuring that the sludge enters the smoldering furnace 1 at a stable flow rate. The precise flow control avoids the problems of material accumulation or insufficient supply, and improves the smoldering efficiency. The rotating material homogenizer 6 rotates synchronously during the descent of the material distribution and sealing cone 5, crushing and leveling the sludge, further optimizing the filling uniformity of the materials in the smoldering furnace 1 and enhancing the smoldering effect. The arch-breaking piece 7 on the connecting rod 44 is driven by the telescopic and rotating unit 4 to stir, and the stirring frequency is synchronized with the lifting frequency, effectively preventing the sludge from caking or bridging in the sludge storage hopper 3, ensuring that the sludge can smoothly and evenly enter the smoldering furnace 1. During continuous feeding, the rotating motor 431 rotates forward and backward in small strokes at a frequency of 10 times per minute, further optimizing the stirring effect, preventing sludge accumulation, and improving the feeding efficiency. The level gauge 8 monitors the sludge height in real time at a frequency of 1 time per second. When the material level is lower than 73%, the external feeding system is automatically started to supplement the sludge to 82%. The automated design reduces manual intervention and improves the stability and reliability of the equipment operation. The external feeding system is linked with the feeding control system and automatically starts and stops according to the feedback of the level gauge 8 to ensure that an appropriate material level is always maintained in the storage hopper, optimizing the operation efficiency of the equipment. The operating speeds of the telescopic cylinder 41 and the rotating motor 431 are precisely designed (such as the rotation speed is 5 - 10 rpm), ensuring the high efficiency and stability of the equipment operation, while reducing the energy consumption and wear of the equipment. At the end of feeding, the material distribution and sealing cone 5 rises and closes the feeding port 11, and at the same time drives the sludge liquid level in the sludge storage hopper 3 to rise to 85%, effectively preventing the leakage of flue gas and improving the sealing performance and environmental protection performance of the equipment. By precisely controlling the actions of the telescopic cylinder 41 and the rotating motor 431, the equipment can operate stably, reducing the downtime caused by mechanical failures and improving the reliability and service life of the equipment.

[0055] Through automated control and real-time monitoring, the equipment can continuously work in a stable operating state, reducing the environmental pollution risk caused by equipment failures or operation errors.

7. The flameless combustion treatment equipment for copper-containing sludge according to claim 1, characterized in that: The height of the sludge in the sludge storage hopper (3) is 73% - 85% of the total height of the sludge storage hopper (3).

8. The flameless combustion treatment equipment for copper-containing sludge according to claim 1, characterized in that: The rotary material distributor (6) has a number of scraping plates (61) with uniform parts. The scraping plates (61) have an inclination angle with the horizontal plane, and a bent part that bends upward is provided at the outer end of the scraping plate (61).

9. A continuous feeding method for a flameless combustion treatment device for copper-containing sludge according to any one of claims 1 to 8, characterized in that, Specifically: Starting feeding: After the feeding control system receives the feeding instruction, the telescopic cylinder (41) and the rotary motor (431) are started. The telescopic cylinder (41) drives the connecting rod to descend at a stroke speed of 10 - 20 nm / s. The material distributing and sealing cone (5) follows the connecting rod (44) to descend and opens the feeding port (11), and the sludge starts to fall. Continuous feeding: During the descending process of the material distributing and sealing cone (5), the sludge is evenly distributed to ensure that the sludge enters the smoldering furnace (1) at a stable flow rate. At the same time, the rotary motor (431) drives the connecting rod (44) to rotate at a rotational speed of 5 - 10 rmp. The arch-breaking pieces (7) on the connecting rod (44) stir the sludge in the sludge storage hopper (3), and the stirring frequency of the arch-breaking pieces (7) is synchronized with the lifting frequency of the telescopic and rotating unit (4) to prevent the sludge from caking and bridging. The material distributing and sealing cone (5) and the rotary material distributor (6) rotate synchronously. The rotary material distributor (6) crushes and levels the sludge to ensure uniform filling of the materials in the smoldering furnace (1). The level gauge (8) monitors the sludge height in real time at a frequency of once per second. When the sludge height is lower than 73% of the sludge storage hopper (3), the feeding control system activates the external feeding system to supplement the sludge to 82% of the sludge storage hopper (3). The feeding speed of the external feeding system is 0.5 - 1.0m 3 / h; End of feeding: After the feeding control system receives the stop instruction, the telescopic cylinder (41) drives the connecting rod (44) to rise. The material distributing and sealing cone (5) closes the feeding port (11) of the smoldering furnace (1), driving the sludge liquid level in the sludge storage hopper (3) to rise to 85% of the sludge storage hopper (3), stopping the sludge from falling, and preparing for the next feeding.

10. The continuous feeding method of the flameless combustion treatment equipment for copper-containing sludge according to claim 9, characterized in that: During the continuous feeding process, the rotary motor (431) performs forward and reverse rotations with small strokes at a frequency of 10 times per minute.
