Description

Technical Field

[0001] The invention relates to the technical field of copper material reprocessing equipment, and in particular to a decontamination combustion furnace for reprocessing copper waste. Background Art

[0002] In the field of copper scrap reprocessing, waste decontamination treatment is required to achieve efficient resource recycling, and incinerators are commonly used processing equipment. However, existing copper scrap decontamination incinerators have many problems that need to be solved. In the feeding process, the sealing performance of the feed port is poor, and the combustion gas leaks seriously, causing a large amount of energy loss and may also bring safety hazards. In terms of decontamination treatment, the internal structure design of the traditional combustion furnace is unreasonable, and the waste is heated unevenly in the furnace and cannot be fully rolled and moved, resulting in oil stains and impurities on the surface of some waste materials. It is difficult to completely remove the oil and impurities, and the decontamination effect is poor; in terms of energy utilization, existing equipment often ignores the waste heat generated by combustion and fails to effectively recycle and utilize it, resulting in a huge waste of energy, increasing the production cost of the enterprise, and not in line with the current green and energy-saving industrial development trend. In view of the above problems, there is an urgent need to develop a new type of copper waste recycling and decontamination combustion furnace to improve stability, enhance decontamination effect, achieve efficient energy utilization, improve environmental protection performance, and meet the development needs of the copper waste recycling industry. This patent came into being. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the technical solution adopted by the present invention to solve its technical problems is: a copper waste reprocessing and decontamination combustion furnace, comprising: a heating chamber, a combustion device is provided inside the heating chamber, a circulation device is provided outside the combustion device, the bottom end of the heating chamber is fixedly connected to a collecting device, and a pulley group is provided outside the collecting device; the combustion device comprises a rotating cylinder, the outer wall of the rotating cylinder is fixedly connected to a gear ring, the outer wall of the gear ring is provided with a driving gear, the inner wall of the rotating cylinder is fixedly connected to a spiral scraper, a dust exhaust groove is opened in the wall of the rotating cylinder, a flamethrower is symmetrically provided on the outside of the rotating cylinder, a feed baffle is provided on the outside of the gear ring, and a discharge baffle is provided at the end of the rotating cylinder away from the feed baffle; the circulation device comprises an exhaust fan, the outer wall of the exhaust fan is fixedly connected to an air condenser, the outer wall of the air condenser is fixedly connected to a connecting pipe, and the end of the connecting pipe away from the air condenser is fixedly connected to a circulation pipe.

[0004] The present invention further provides that the outer wall of the gear ring is rotatably connected to the inner wall of the heating chamber, the end of the rotating drum away from the gear ring is rotatably connected to the inner wall of the heating chamber, the drive gear is rotatably connected to the inner wall of the heating chamber, the drive gear meshes with the gear ring, and the outer wall of the flamethrower is fixedly connected to the inner wall of the heating chamber. When the copper scrap enters the rotating drum, an external servo motor drives the drive gear to rotate, which meshes with the gear ring to drive the rotating drum. The spiral scraper inside the rotating drum pushes the scrap to roll and move within the drum, causing it to burn more fully. Simultaneously, the flamethrower sprays flames to heat and burn the scrap, removing oil stains and impurities from the scrap surface. The scrap continuously turns within the rotating drum, ensuring that all parts of the scrap are fully heated.

[0005] The present invention further provides that the outer wall of the feed baffle is fixedly connected to the outer wall of the heating bin, the outer wall of the feed baffle is fixedly connected to the feed bin, the inner wall of the feed bin is rotatably connected to a rotating plate, the outer wall of the rotating plate is fixedly connected to a torsion spring, the other end of the torsion spring is fixedly connected to the outer wall of the feed bin, and the inner wall of the feed baffle is fixedly connected to a feed guide plate. Copper scrap enters the heating bin through the feed bin, and the rotating plate in the feed bin rotates under the action of the weight of the scrap, overcoming the resistance of the torsion spring, allowing the scrap to slide through the feed guide plate into the rotating drum. The feed baffle serves as a guide and preliminary barrier to ensure orderly entry of the scrap. After the copper scrap passes through the feed baffle, the torsion spring acts to rotate and reset the feed baffle, preventing a large amount of combustion gas from the heating bin from being discharged.

[0006] The present invention further provides that the outer wall of the discharge baffle is fixedly connected to the outer wall of the heating chamber, the inner wall of the discharge baffle is rotatably connected to a baffle, and the outer wall of the discharge baffle is fixedly connected to a discharge guide plate. Under the rotation of the rotating drum, the cleaned copper scrap is discharged from the discharge baffle through the discharge guide plate. The baffle can prevent the scrap from being discharged too quickly to a certain extent. Under the action of gravity, when no cleaned copper scrap passes through, the baffle rotates and resets, thereby preventing the loss of large amounts of smoke and temperature.

[0007] The present invention further provides that the outer wall of the vacuum pump is fixedly connected to the outer wall of the heating chamber, the outer wall of the circulation pipe is fixedly connected to the inner wall of the heating chamber, the circulation pipe is disposed outside the rotating drum, and an exhaust assembly is fixedly connected to the end of the circulation pipe remote from the connecting pipe. The vacuum pump draws exhaust gas generated by combustion into the circulation pipe through the air collecting hood and the connecting pipe. The exhaust gas flows within the circulation pipe. Because the circulation pipe is disposed within the heating chamber, the circulating high-temperature gas heats and insulates the heating chamber, thereby utilizing the heat energy.

[0008] The present invention further provides that the exhaust assembly includes an exhaust pipe, wherein fins are fixedly connected to the inner wall of the exhaust pipe, a rotating rod is rotatably connected to the inner wall of the exhaust pipe, an impeller is fixedly connected to the outer wall of the rotating rod, and a scraper is fixedly connected to the outer wall of the impeller. The fins dissipate heat from the exhaust pipe to prevent burns caused by direct discharge. The impeller in the exhaust pipe drives the rotating rod to rotate under the influence of the exhaust gas flow, and the scraper on the impeller scrapes dust and other impurities adhering to the fins to prevent clogging.

[0009] The present invention further provides a configuration in which the outer wall of the exhaust tube is fixedly connected to the outer wall of the circulation pipe, the inner wall of the scraper is slidably connected to the outer wall of the fin, the inner wall of the exhaust tube is threadedly connected to a placement tube, the inner wall of the placement tube is symmetrically fixedly connected to a filter, a dust outlet is formed in the wall of the exhaust tube, and the outer wall of the exhaust tube is slidably connected to a dust box. The filter in the placement tube further filters the exhaust gas, and the purified exhaust gas is discharged. The scraped dust falls from the dust outlet into the dust box, which collects the filtered impurities. The dust box and the exhaust tube are magnetically connected, making it easy to disassemble and clean.

[0010] The present invention is further configured such that the collecting device includes a bottom bin, an inclined groove is provided at the top of the bottom bin, a rotating roller is fixedly connected to the inner wall of the bottom bin, a dust inlet groove is provided in the wall of the rotating roller, a cleaning port is provided on the outer wall of the bottom bin, and a filter plate is provided inside the bottom bin.

[0011] The present invention is further configured such that the top of the bottom bin is fixedly connected to the bottom of the heating bin, the outer wall of the rotating roller is slidably connected to the inner wall of the dust inlet trough, the rotating roller is connected to a drive gear via a pulley assembly, an eccentric wheel is fixedly connected to the outer wall of the rotating roller, and an extrusion block is fixedly connected to the outer wall of the filter plate. The inclined groove at the top of the bottom bin facilitates the sliding of dust and other impurities into the dust inlet trough on the rotating roller. The driving gear drives the rotating roller to rotate via the pulley assembly, bringing dust into the interior of the bottom bin. The configuration of the rotating roller ensures that a fixed amount of dust is introduced each time, preventing dust from flying into the heating bin.

[0012] The present invention is further configured such that the inner walls at the four corners of the filter plate are slidably connected to a limiting rod, the outer wall of the limiting rod is fixedly connected to a push spring, the end of the push spring away from the limiting rod is fixedly connected to the outer wall of the filter plate, the outer wall of the limiting rod is fixedly connected to the inner wall of the bottom bin, and the outer wall of the extrusion block is slidably connected to the outer wall of the eccentric wheel.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention realizes automatic feeding of copper scrap by setting a combustion device and cooperating the rotating plate and the torsion spring in the feed bin, which does not require frequent manual operation and improves work efficiency. The feed baffle is reset in time after the waste enters, effectively preventing the leakage of combustion gas in the heating bin, maintaining a stable combustion environment, and reducing energy loss. The driving gear and the gear ring drive the rotating cylinder to rotate, and cooperate with the internal spiral scraper to make the waste roll and move fully in the cylinder. The flamethrower heats and burns in all directions, ensuring that all parts of the waste can be fully heated, greatly improving the decontamination effect, realizing deep cleaning treatment of copper scrap, and improving the cleaning effect.

[0014] 2. The present invention sets a circulation device, and the circulation pipe is set inside the heating chamber to recycle the high-temperature exhaust gas generated by combustion, insulate and heat the heating chamber, realize the secondary utilization of thermal energy, reduce the energy consumption of equipment operation, improve energy utilization rate, reduce energy waste, and meet the needs of green and energy-saving industrial development.

The end of the rotating cylinder 51 away from the gear ring 52 is rotatably connected to the inner wall of the heating chamber 1. The drive gear 56 is rotatably connected to the inner wall of the heating chamber 1 and meshes with the gear ring 52. The outer wall of the flamethrower 53 is fixedly connected to the inner wall of the heating chamber 1. An external servo motor drives the drive gear 56 to rotate, which meshes with the gear ring 52 to drive the rotating cylinder 51. The spiral scraper 510 inside the rotating cylinder 51 pushes the waste to roll and move within the cylinder, causing it to burn more completely. At the same time, the flamethrower 53 sprays flames to heat and burn the waste, removing oil stains and impurities from the waste surface. The waste is continuously turned within the rotating cylinder 51, ensuring that every part of the waste is fully heated.

[0023] The outer wall of the feed baffle 54 is fixedly connected to the outer wall of the heating bin 1. The outer wall of the feed baffle 54 is fixedly connected to the feed bin 55. The inner wall of the feed bin 55 is rotatably connected to a rotating plate 57. The outer wall of the rotating plate 57 is fixedly connected to a torsion spring 58. The other end of the torsion spring 58 is fixedly connected to the outer wall of the feed bin 55. The inner wall of the feed baffle 54 is fixedly connected to a feed guide plate 59. Under the action of the weight of the waste, the rotating plate 57 in the feed bin 55 overcomes the resistance of the torsion spring 58 and rotates, allowing the waste to slide through the feed guide plate 59 and into the rotating cylinder 51. The feed baffle 54 plays a guiding and preliminary blocking role, ensuring that the waste enters in an orderly manner. When the copper waste passes through the feed baffle 54, the feed baffle 54 rotates and resets under the action of the torsion spring 58, preventing a large amount of combustion gas from the heating bin 1 from being discharged.

The inner wall of the discharge baffle 512 is rotatably connected to the baffle 511, and the outer wall of the discharge baffle 512 is fixedly connected to the discharge guide plate 513. Under the rotation of the rotating drum 51, the cleaned copper scrap is discharged from the discharge baffle 512 through the discharge guide plate 513. The baffle 511 can prevent the scrap from being discharged too quickly to a certain extent. Under the action of gravity, when no cleaned copper scrap passes through, the baffle 511 rotates and resets, also preventing the loss of large amounts of smoke and temperature.

[0025] The outer wall of the exhaust fan 31 is fixedly connected to the outer wall of the heating chamber 1, and the outer wall of the circulation pipe 34 is fixedly connected to the inner wall of the heating chamber 1. The circulation pipe 34 is located outside the rotating drum 51, and the end of the circulation pipe 34 away from the connecting pipe 33 is fixedly connected to the exhaust assembly 35. When the exhaust fan 31 is started, the exhaust fan 31 draws the exhaust gas generated by the combustion into the circulation pipe 34 through the wind collecting cover 32 and the connecting pipe 33. The exhaust gas flows in the circulation pipe 34. Because the circulation pipe 34 is located inside the heating chamber 1, the circulating high-temperature gas heats and insulates the heating chamber 1, thereby utilizing the heat energy.

[0026] Exhaust assembly 35 includes an exhaust tube 351, the inner wall of which is fixedly connected a fin 352. A rotating rod 354 is rotatably connected to the inner wall of exhaust tube 351. An impeller 353 is fixedly connected to the outer wall of rotating rod 354. A scraper 355 is fixedly connected to the outer wall of impeller 353. Fins 352 dissipate heat from exhaust tube 351, preventing burns caused by direct exhaust. The impeller 353 within exhaust tube 351 rotates the rotating rod 354 under the influence of the exhaust gas flow. The scraper 355 on impeller 353 scrapes away dust and other impurities adhering to the fins 352, preventing clogging.

A dust box 357 is slidably connected to the outer wall of the exhaust tube 351. The filter 359 in the mounting tube 358 further filters the exhaust gas, and the purified exhaust gas is discharged. The scraped dust falls from the dust discharge port 356 into the dust box 357, which collects the filtered impurities. The dust box 357 and the exhaust tube 351 are magnetically connected, making it easy to disassemble and clean.

[0028] The collection device 2 includes a bottom bin 21, the top of which is provided with an inclined slot 24. A rotating roller 22 is fixedly connected to the inner wall of the bottom bin 21. A dust inlet slot 23 is provided in the wall of the rotating roller 22. A cleaning port 210 is provided on the outer wall of the bottom bin 21. A filter plate 25 is provided inside the bottom bin 21. Dust and other impurities generated during the combustion and decontamination process fall into the bottom bin 21 through the dust discharge slot 514 on the wall of the rotating cylinder 51. The inclined slot 24 at the top of the bottom bin 21 facilitates the sliding of dust and other impurities into the dust inlet slot 23 on the rotating roller 22. The driving gear 56 drives the rotating roller 22 to rotate via the pulley assembly 6, bringing dust into the interior of the bottom bin 21. The arrangement of the rotating roller 22 ensures that a fixed amount of dust enters each time, preventing dust from flying into the heating chamber 1.

[0029] The top of the bottom bin 21 is fixedly connected to the bottom of the heating bin 1. The outer wall of the rotating roller 22 is slidably connected to the inner wall of the dust inlet trough 23. The rotating roller 22 is connected to the drive gear 56 via a pulley assembly 6. The outer wall of the rotating roller 22 is fixedly connected to the eccentric wheel 26, and the outer wall of the filter plate 25 is fixedly connected to the extrusion block 27. When the eccentric wheel 26 on the rotating roller 22 rotates, it squeezes the extrusion block 27 on the filter plate 25, causing the filter plate 25 to slide up and down on the limit rod 28, pushing the spring 29 to act as a buffer and reset, screening different impurities, and thus collecting and processing them according to their different impurities. Impurities in the bottom bin 21 can be regularly cleaned through the cleaning port 210.

[0030] The inner walls of the four corners of the filter plate 25 are slidably connected to the limit rods 28, and the outer wall of the limit rods 28 is fixedly connected to the push springs 29. The end of the push springs 29 away from the limit rods 28 is fixedly connected to the outer wall of the filter plate 25. The outer wall of the limit rods 28 is fixedly connected to the inner wall of the bottom bin 21, and the outer wall of the extrusion block 27 is slidably connected to the outer wall of the eccentric wheel 26.

[0031] Working principle: During use, the copper scrap enters the heating chamber 1 through the feed bin 55. The rotating plate 57 in the feed bin 55 overcomes the resistance of the torsion spring 58 and rotates under the action of the scrap weight, so that the scrap slides into the rotating cylinder 51 through the feed guide plate 59. The feed baffle 54 plays a guiding and preliminary blocking role to ensure that the scrap enters in an orderly manner. When the copper scrap passes through the feed baffle 54, the feed baffle 54 rotates and resets under the action of the torsion spring 58 to prevent the combustion gas in the heating chamber 1 from being discharged in large quantities, thus avoiding frequent manual operations, improving work efficiency, and preventing the scrap from overflowing. When the copper scrap enters the rotating drum 51, the external servo motor drives the driving gear 56 to rotate, meshing with the gear ring 52 to drive the rotating drum 51 to rotate. The spiral scraper 510 in the rotating drum 51 pushes the scrap to roll and move in the drum, making it burn more fully. At the same time, the flamethrower 53 sprays flames to heat and burn the scrap, removing oil stains and impurities on the surface of the scrap. The scrap is continuously turned in the rotating drum 51, ensuring that all parts are fully heated, improving the decontamination effect, and making the copper scrap more thoroughly processed. During the combustion and decontamination process, the exhaust fan 31 is started through the provided circulation device 3. The exhaust fan 31 sucks the exhaust gas generated by the combustion into the circulation pipe 34 through the wind collecting hood 32 and the connecting pipe 33. The exhaust gas flows in the circulation pipe 34. Since the circulation pipe 34 is provided inside the heating chamber 1, the circulating high-temperature gas heats the heating chamber 1 and utilizes the heat energy. Finally, the exhaust gas is discharged from the exhaust assembly 35. The heat in the exhaust pipe 351 is dissipated by the provided fins 352 to prevent burns caused by direct discharge. The impeller 353 in the exhaust pipe 351 The exhaust gas flow drives the rotating rod 354 to rotate, and the scraper 355 on the impeller 353 scrapes off dust and other impurities attached to the fins 352 to prevent blockage. The filter 359 in the cylinder 358 further filters the exhaust gas, and the purified exhaust gas is discharged. The scraped dust falls into the dust box 357 from the dust discharge port 356. The dust box 357 collects the filtered impurities. The dust box 357 and the exhaust pipe 351 are magnetically connected to facilitate disassembly and cleaning. This process effectively treats the exhaust gas generated by combustion, reduces environmental pollution, and ensures that the discharged gas meets environmental protection standards. The cleaned copper scrap is discharged from the discharging baffle 512 through the discharging guide plate 513 under the rotation of the rotating drum 51. The baffle 511 can prevent the scrap from being discharged too quickly to a certain extent. Under the action of gravity, when there is no cleaned copper scrap passing through, the baffle 511 rotates and resets, which can also prevent the loss of a large amount of smoke and temperature. The discharging process is stable and orderly, ensuring the smooth output of the treated copper scrap. The dust collecting device 2 is provided, and the dust and other impurities generated during the combustion and decontamination process fall into the bottom bin 21 through the dust discharge groove 514 on the wall of the rotating cylinder 51. The inclined groove 24 at the top of the bottom bin 21 makes it convenient for the dust and other impurities to slide into the dust inlet groove 23 on the rotating roller 22. The driving gear 56 drives the rotating roller 22 to rotate through the pulley group 6, and brings the dust into the interior of the bottom bin 21. By setting the rotating roller 22, the dust can be quantitatively entered each time to prevent the dust from flying into the heating bin 1. When the eccentric wheel 26 on the rotating roller 22 rotates, the extrusion block 27 on the filter plate 25 is squeezed to make the filter plate 25 slide up and down on the limit rod 28, pushing the spring 29 to play a buffering and resetting role, screening different impurities, thereby collecting and processing according to different impurities. The impurities in the bottom bin 21 can be cleaned regularly through the cleaning port 210. The collecting device 2 can effectively collect impurities generated during the combustion process, keep the interior of the equipment clean, and avoid impurity accumulation affecting the normal operation of the equipment.
