Description

Technical Field

[0001] The present invention relates to the technical field of coating kettles, specifically a vertical high-temperature coating kettle. Background Art

[0002] With the continuous development of the new energy industry, the product quality of lithium battery raw materials is getting higher and higher, and the process of coating the negative electrode material at high temperature is one of the key links. After the raw materials enter the equipment, they are first heated by a radiation high-temperature heating device. When the temperature reaches the set value, the viscous liquid medium uniformly mixes and coats the powdery medium under the action of the stirring shaft.

[0003] In the industry, the equipment for producing more negative electrode materials is a horizontal coating kettle and a vertical coating kettle. They both use internal and external spiral belts welded to the shaft to form a stirring component for stirring and coating. Among them, the cleaning and maintenance of the vertical coating kettle are relatively difficult because the materials accumulate in the kettle. When cleaning, the materials need to be emptied, and there may be hard-to-reach dead corners inside the kettle body, increasing the cleaning difficulty. At the same time, due to its structural characteristics, the materials in the vertical coating kettle often form a natural accumulation, which may lead to poor fluidity of the materials, especially when dealing with materials with high viscosity and easy caking. Poor fluidity may lead to uneven reactions and affect the product quality. Due to the high-temperature reaction in the coating kettle, the generated high-temperature flue gas is directly discharged, which not only pollutes the environment but also causes energy waste. Therefore, there is a need in the market for an efficient energy-saving coating kettle that can make the stirring more uniform and is easy to clean. Summary of the Invention

[0004] The purpose of the present invention is to provide a vertical high-temperature coating kettle to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: The vertical high-temperature coating kettle includes a kettle body. A support frame is installed at the bottom end of the kettle body, a heat recovery device is installed at the top end of the kettle body, a drive assembly is installed at the top end of the kettle body, a stirring assembly is rotatably installed inside the kettle body, the output end of the drive assembly penetrates the kettle body and is rotatably connected to the stirring assembly. The heat recovery device is used to recover the heat of the high-temperature flue gas and provide hot water for flushing. The drive assembly is used to drive the stirring assembly and control the rotation speed of the stirring assembly. The stirring assembly is used to stir the reactants, assist in feeding, and clean the inside of the kettle body. A control system is installed inside the drive assembly, and the control system is used to control the entire coating kettle.

[0006] The stirring assembly includes a spiral stirring device. A scraping wall stirring device is installed on the spiral stirring device. A stirring and flushing device is installed on the spiral stirring device. The stirring and flushing device is rotatably connected to the kettle body and rotatably connected to the output end of the drive assembly. From the top of the stirring and flushing device to the bottom of the kettle body is a non-stirring area, and dust will adhere to the non-stirring area as the stirring and flue gas rise.

[0007] The scraping and stirring device includes a first connecting shell, on which a scraping link is installed. At the bottom end of the first connecting shell, a cross link is rotatably installed. A scraping blade is installed on the scraping link. The first connecting shell is respectively connected to a spiral stirring device and a stirring and flushing device. The scraping blade is used to scrape the dust in the non-stirring area. Sealing layers are provided at the installation positions of the scraping link and the cross link with the first connecting shell.

[0008] The spiral stirring device includes a second connecting shell. On the side of the second connecting shell, a spiral cross link is rotatably installed. At the top end of the second connecting shell, an upper spiral sleeve is rotatably installed. At the bottom end of the second connecting shell, a lower spiral sleeve is rotatably installed. A spiral blade is installed on the lower spiral sleeve. The spiral cross link is rotatably connected to the first connecting shell. Sealing layers are provided at the rotational connection positions of the second connecting shell with the spiral cross link, the lower spiral sleeve, and the upper spiral sleeve.

[0009] The raw materials are added into the kettle body. The control system starts the driving component. The output end of the driving component drives the upper spiral link to rotate through a pulley. The upper spiral link drives the spiral cross links on both sides and the lower spiral link at the bottom end to rotate. The spiral cross link drives the entire scraping and stirring device and the stirring and flushing device to rotate through the first connecting shell, so that the stirring and flushing device rotates as a whole to stir the raw materials, and the scraping and stirring device rotates to scrape and clean the non-stirring area from the top of the stirring and flushing device to the bottom of the kettle body, preventing dust from adhering to the inner wall of the non-stirring area of the kettle body.

[0010] The upper spiral sleeve penetrates through the second connecting shell and is installed with a second upper bevel gear. The lower spiral sleeve penetrates through the second connecting shell and is installed with a second lower bevel gear. An upper spiral link is rotatably installed inside the upper spiral sleeve. The upper spiral link is internally connected to the heat recovery device. The spiral cross link penetrates through the second connecting shell and is installed with a second side bevel gear. Sealing bearings are installed on both sides of the upper spiral link. The upper spiral link is rotatably connected to the spiral cross link through the sealing bearings. The upper spiral link and the spiral cross link are internally connected. The second upper bevel gear meshes and drives with the second side bevel gear. The second side bevel gear meshes and drives with the second lower bevel gear. A lower spiral link is rotatably installed inside the lower spiral sleeve. The lower spiral link is connected to the bottom end of the upper spiral link.

[0011] The sealing bearing is a bearing structure and is provided with a sealing layer to prevent internal liquid leakage; the upper spiral link and the spiral cross link are hollow rods.

[0012] Since both the upper spiral sleeve and the second upper bevel gear are fixed and do not rotate, when the spiral cross-link rotates around the central axis of the upper spiral link, the second side bevel gear meshes with the second upper bevel gear, causing the second side bevel gear to drive the spiral cross-link to rotate around its own central axis. The rotation of the second side bevel gear drives the second lower bevel gear to rotate, and the second bevel gear drives the lower spiral sleeve to rotate around its own central axis. At this time, the rotation direction of the lower spiral sleeve is opposite to the rotation direction of the upper spiral link. The lower spiral sleeve drives the spiral blade to rotate, and the rotation of the spiral blade drives the raw materials at the bottom to turn up, preventing the materials from settling at the bottom and causing insufficient reaction and caking. At the same time, when the stirring and flushing device rotates in one direction as a whole, it will drive the raw materials to rotate in a fixed direction to generate eddies, resulting in the materials in the eddies not being fully stirred. At this time, the spiral blade rotates reversely in the center of the stirring and flushing device, turning up the raw materials at the bottom and reversely impacting the raw materials in the eddy. The raw materials collide with each other to destroy the eddy, so as to make the stirring uniform. The fine lumps are broken up during the impact and stirring, making the reaction more sufficient. When discharging, the control system controls the spiral blade to rotate reversely, and the spiral blade drives the finished product to rotate downward, quickly completing the discharging and preventing the bottom discharging port from being blocked.

[0013] A scraping wall connecting pipe is installed inside the first connecting shell. The scraping wall connecting rod passes through the first connecting shell and is rotatably installed with a first upper bevel gear. The cross connecting rod passes through the first connecting shell and is installed with a first lower bevel gear. The spiral cross-link passes through the first connecting shell and is installed with a first side bevel gear. A sealing bearing is installed on the scraping wall connecting pipe. The spiral cross-link is rotatably connected to the scraping wall connecting rod through the sealing bearing. The cross connecting rod is rotatably connected to the bottom end of the scraping wall connecting pipe through the sealing bearing. The scraping wall connecting rod is connected to the top end of the scraping wall connecting pipe. The scraping wall connecting pipe is internally communicated with the spiral cross-link and the cross connecting rod respectively.

[0014] The self-rotation of the spiral cross-link drives the first side bevel gear at the other end to rotate. The rotation of the first side bevel gear drives the first upper bevel gear and the first lower bevel gear to rotate. The first lower bevel gear drives the cross connecting rod to rotate. The cross connecting rod drives the flushing connecting pipe to rotate. The flushing connecting pipe drives the scraping blade rod to rotate through the connecting baffle and the end baffle. The rotation of the scraping blade rod stirs the raw materials while scraping the inner wall of the kettle body, so that the viscous medium adhered to it is scraped off and reacts with the powdery medium along with the stirring. The spiral blade between the flushing connecting pipes rotates to stir and turn up the raw materials and destroys the eddies generated by the self-rotation of the spiral stirring device.

[0015] A vibrating scraping blade is installed on the scraping wall connecting rod. A vibrating ring is installed at the top end of the first upper bevel gear. A vibrating housing is installed on one side of the vibrating ring. The bottom end of the vibrating housing is connected to the bottom end of the first upper bevel gear. A vibrating head is slidably installed on the vibrating ring. The vibrating head passes through the vibrating housing. A spring retaining piece is installed on the vibrating head. A vibrating spring is installed between the spring retaining piece and the vibrating ring. The vibrating spring is located inside the vibrating housing. The vibrating head passes through the vibrating spring.

[0016] The first upper bevel tooth rotates on the scraper connecting rod, driving the vibration head at the top of the first bevel gear to rotate. The vibration head rotates and hits the fixed non-rotating vibration scraper to generate vibration. At the same time, it slides and shrinks along the vibration shell due to the impact force. When the vibration head passes the vibration scraper, it is quickly reset by the elastic force of the vibration spring. At the same time, when resetting, the bottom of the vibration head hits the outside of the vibration ring to generate vibration. This cycle causes the first upper bevel gear and the scraper connecting rod to vibrate. The scraper connecting rod drives the scraper blades to vibrate, so that the dust in the non-stirring area of ​​the kettle body is further vibrated and falls. The first upper bevel gear transmits the vibration to the first side bevel gear and the first lower bevel gear, and finally drives the stirring and flushing device to vibrate. The vibration breaks the lumps in the raw materials, thereby fully reacting them. The finished products and unreacted powdered media stuck to the stirring and flushing device are also shaken off during the unloading process.

[0017] The stirring and flushing device includes a flushing connecting pipe, which is connected to the inside of the cross connecting rod, and spiral blades are installed between the flushing connecting pipes. A plurality of telescopic spray devices are installed on the flushing connecting pipe, and the telescopic spray device is connected to the inside of the flushing connecting pipe. A connecting baffle is installed on the flushing connecting pipe, and end baffles are installed at both ends of the connecting baffle. A scraper rod is rotatably installed between the end baffles, and the scraper rod is meshed with the telescopic spray device for transmission.

[0018] The telescopic spraying device includes a flushing shell, which is installed on a flushing connecting pipe. A water inlet plate is installed on the flushing shell, which is connected to the flushing connecting pipe. A water inlet hole communicating with the flushing connecting pipe is provided on the water inlet plate. A telescopic spray head is slidably installed in the flushing shell, a flushing spring is installed between the telescopic spray head and the flushing shell, a thread is provided on the telescopic spray head, and the telescopic spray head is engaged with the scraper rod through the thread for transmission.

[0019] The gas-liquid mixture flows from the upper spiral connecting rod into the spiral cross connecting rod, then flows into the flushing connecting pipe through the cross connecting rod, and finally enters the water inlet hole of the water inlet plate. Driven by the high-pressure gas-liquid mixture, the telescopic nozzle overcomes the elastic force of the flushing spring, slides and extends in the flushing outer shell, and the sliding of the telescopic nozzle drives the two closed scraper rods to rotate and open. The telescopic nozzle is fully extended and sprays a high-temperature and high-pressure gas-liquid mixture, and cooperates with the rotation of the stirring and flushing device to complete the cleaning of the inner wall of the kettle body and the spiral stirring device, and also completes the self-cleaning between the stirring and flushing devices. The high-temperature gas-liquid mixture will clean the high-melting-point residues remaining on the stirring assembly in the kettle box, and cooperate with the vibration of the stirring assembly to shake off the dust on the stirring assembly in the kettle box and be washed away together, thereby achieving the purpose of self-cleaning of the kettle body and the stirring assembly.

[0020] The heat recovery device includes a heat-insulating outer shell, a smoke inlet pipe and a smoke outlet pipe. The heat-insulating outer shell is installed on the kettle body. A heating water tank is installed inside the heat-insulating outer shell. A heating water pipe is installed on the heating water tank. The heating water pipe is internally connected to the heating water tank. A flue gas partition is provided inside the heating water tank. The heating water pipe penetrates through the flue gas partition. The flue gas partition and the top end of the water tank form a sealed chamber. One end of the smoke inlet pipe penetrates through the heating water tank and is internally connected to the sealed chamber. The other end of the smoke inlet pipe is internally connected to the kettle body. A smoke outlet pipe is provided on the heat-insulating outer shell. The smoke outlet pipe is located at the top end of the sealed chamber. An expansion top cover is provided at the top end of the heat-insulating outer shell. A steam chamber is formed between the expansion top cover and the flue gas partition.

[0021] A water pump is externally connected to the heating water tank. The water pump is used to supply water to the water tank. Electric valves are provided on the smoke inlet pipe, the smoke outlet pipe, the upper spiral connecting rod and the heating water pipe; The expansion top cover is made of an expandable high-temperature resistant material, and the heat-insulating outer shell is made of a heat-insulating material; A gas-liquid stirring device is installed inside the heating water tank, which is used to mix the water vapor and the hot water in the water tank. An air pump is externally connected to the steam chamber, and the air pump is used to pressurize the steam chamber.

[0022] When the high-temperature flue gas in the kettle body needs to be discharged, the control system controls the electric valve on the smoke inlet pipe to open. The high-temperature flue gas enters the sealed chamber along the smoke inlet pipe. The high-temperature flue gas exchanges heat with the low-temperature water in the heating water pipe, causing the water to absorb heat and evaporate. At this time, the electric valve on the heating water pipe is opened, and the steam flows from the heating water pipe into the steam chamber. The water pump supplies water to the water tank to make up for the water in the heating water tank. When the feeding is completed and the kettle body is cleaned, the electric valve on the upper spiral connecting rod is opened, and the gas-liquid stirring device is used to mix the water vapor, hot water and air. The air pump is opened to pressurize the steam chamber, and the gas-liquid mixture flows into the upper spiral connecting rod under high pressure.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. The heat recovery device is used to absorb the heat of the high-temperature flue gas generated by the reaction in the kettle body, and the absorbed heat is used to heat cold water to generate water vapor and hot water. The water vapor, hot water and air are mixed to generate a high-temperature and high-pressure gas-liquid mixture. The gas-liquid mixture is used to cooperate with the rotation and vibration of the stirring assembly to complete the cleaning of the kettle body and the self-cleaning of the stirring assembly itself, and clean the high-melting-point residues and dust.

[0024] 2. The scraping wall stirring device is used to scrape the dust in the non-stirring area and cooperate with the vibration to make the dust fall off; The spiral blades on the spiral stirring device rotate reversely at the center of the stirring and flushing device, causing the raw materials at the bottom to turn up and reversely impact the raw materials in the eddy current. The eddy current is destroyed by the mutual collision of the raw materials, making the stirring uniform, causing the fine agglomerates to break up during the impact and turning, preventing the raw materials from caking, and making the reaction more sufficient; When feeding, the control system controls the spiral blades to rotate reversely, and the spiral blades drive the finished product to rotate downward, quickly completing the feeding and preventing the bottom feeding port from being blocked.

[0025] 3. The overall stirring, self-rotation stirring, and upward turning of raw materials are completed by the stirring and rinsing device, preventing the raw materials from caking and making the raw material mixing more uniform. At the same time, in cooperation with vibration, the caking is quickly broken during stirring and vibration, improving the production efficiency. The inner wall of the kettle body is scraped by the scraping rod to prevent the raw materials from sticking to the inner wall of the kettle body. The integrated telescopic spraying and rinsing device is used to complete the cleaning of the kettle body and the spiral stirring device, as well as the self-cleaning of the stirring and rinsing device.

The telescopic spraying and flushing devices 535 are internally communicated with the flushing connecting pipe 536. A connecting baffle 534 is installed on the flushing connecting pipe 536. End baffles 537 are installed at both ends of the connecting baffle 534. A scraping rod 531 is rotatably installed between the end baffles 537. The scraping rod 531 is meshed and driven with the telescopic spraying and flushing device 535.

[0050] The telescopic flushing device 535 includes a flushing housing 5353, which is installed on the flushing connecting pipe 536. An inlet plate 5351 is installed on the flushing housing 5353. The inlet plate 5351 is connected to the flushing connecting pipe 536. The inlet plate 5351 is provided with an inlet hole communicating with the flushing connecting pipe 536. A telescopic nozzle 5352 is slidably installed in the flushing housing 5353. A flushing spring 5354 is installed between the telescopic nozzle 5352 and the flushing housing 5353. The telescopic nozzle 5352 is provided with threads, and the telescopic nozzle 5352 is in meshing transmission with the wiper rod 531 through the threads.

[0051] The working principle of the present invention: Add raw materials into the kettle body 1. The control system turns on the driving component 3. The output end of the driving component 3 drives the upper spiral connecting rod 521 to rotate through a pulley. The upper spiral connecting rod 521 drives the spiral cross connecting rods 5210 on both sides and the lower spiral connecting rod 528 at the bottom to rotate. The spiral cross connecting rod 5210 drives the entire scraping and stirring device 51 and the stirring and flushing device 53 to rotate through the first connecting shell 511, so that the stirring and flushing device 53 rotates as a whole to stir the raw materials, and the scraping and stirring device 51 rotates to scrape and clean the non-stirring area from the top of the stirring and flushing device 53 to the bottom of the kettle body 1, preventing dust from adhering to the inner wall of the non-stirring area of the kettle body 1.

[0052] Since the upper spiral sleeve 522 and the second upper bevel gear 523 are both fixed and do not rotate, when the spiral cross connecting rod 5210 rotates around the central axis of the upper spiral connecting rod 521, the second side bevel gear 526 meshes with the second upper bevel gear 523, so that the second side bevel gear 526 drives the spiral cross connecting rod 5210 to rotate around its own central axis. The rotation of the second side bevel gear 526 drives the second lower bevel gear 527 to rotate, and the second bevel gear drives the lower spiral sleeve 525 to rotate around its own central axis. At this time, the rotation direction of the lower spiral sleeve 525 is opposite to the rotation direction of the upper spiral connecting rod 521. The lower spiral sleeve 525 drives the spiral blade 529 to rotate, and the rotation of the spiral blade 529 drives the raw materials at the bottom to turn up, avoiding the situation that the materials sink to the bottom, resulting in insufficient reaction and caking. At the same time, when the stirring and flushing device 53 rotates as a whole in one direction, it will drive the raw materials to rotate in a fixed direction to generate a vortex, resulting in the materials in the vortex not being fully stirred. At this time, the spiral blade 529 rotates reversely at the center of the stirring and flushing device 53, turning up the raw materials at the bottom and reversely impacting the raw materials in the vortex. The raw materials collide with each other to break the vortex, so that the stirring is uniform, and the fine caking is broken up during the impact and agitation, making the reaction more sufficient. When discharging, the control system controls the spiral blade 529 to rotate reversely, and the spiral blade 529 drives the finished product to rotate downward, quickly completing the discharging and preventing the bottom discharging port from being blocked.

[0053] The spiral cross connecting rod 5210 rotates itself, driving the first side bevel gear 514 at the other end to rotate. The rotation of the first side bevel gear 514 drives the first upper bevel gear 512 and the first lower bevel gear 517 to rotate. The first lower bevel gear 517 drives the cross connecting rod 533 to rotate. The cross connecting rod 533 drives the flushing connecting pipe 536 to rotate. The flushing connecting pipe 536 drives the wiper rod 531 to rotate through the connecting baffle 534 and the end baffle 537. As the wiper rod 531 rotates, it stirs the raw materials while scraping the inner wall of the kettle body 1, scraping off the viscous medium adhered to it, and reacting with the powdery medium during stirring. The spiral blade 532 between the flushing connecting pipes 536 rotates to stir and turn over the raw materials, and destroys the eddy current generated by the rotation of the spiral stirring device 52.

[0054] The first upper bevel gear rotates itself on the scraping wall connecting rod 513, driving the vibration head 5121 at the top of the first bevel gear to rotate. The rotation of the vibration head 5121 hits the fixed non-rotating vibration wiper 5131 to generate vibration, and at the same time slides and contracts along the vibration housing 5123 under the impact force. When the vibration head 5121 rotates past the vibration wiper 5131, it is subjected to the elastic force of the vibration spring 5124, causing it to quickly reset. At the same time, when resetting, the bottom of the vibration head 5121 hits the outside of the vibration ring 5122 to generate vibration. This cycle causes the first upper bevel gear 512 and the scraping wall connecting rod 513 to vibrate. The scraping wall connecting rod 513 drives the scraping wall blade 518 to vibrate, causing the dust in the non-stirring area of the kettle body 1 to further fall due to vibration. The first upper bevel gear 512 transmits the vibration to the first side bevel gear 514 and the first lower bevel gear 517, ultimately driving the stirring and flushing device 53 to vibrate. The vibration breaks the lumps in the raw materials, enabling full reaction, and also shakes off the finished products and unreacted powdery medium adhered to the stirring and flushing device 53 during the feeding process.

[0055] When the high-temperature flue gas in the kettle body 1 needs to be discharged, the control system controls the electric valve on the smoke inlet pipe 24 to open. The high-temperature flue gas enters the closed chamber 28 along the smoke inlet pipe 24. The high-temperature flue gas exchanges heat with the low-temperature water in the heating water pipe 22, causing the water to absorb heat and evaporate. At this time, the electric valve on the heating water pipe 22 is opened, and the steam flows from the heating water pipe 22 into the steam chamber 29. The water pump supplies water to the water tank to make up the water in the heating water tank 23. When the feeding is completed and the kettle body 1 is cleaned, the electric valve on the upper spiral connecting rod 521 is opened, and the gas-liquid stirring device is used to mix water vapor, hot water, and air. The air pump is turned on to pressurize the steam chamber 29, and the gas-liquid mixture flows into the upper spiral connecting rod 521 under high pressure.

[0056] The gas-liquid mixture flows into the spiral cross connecting rod 5210 from the upper spiral connecting rod 521, then flows into the flushing connecting pipe 536 through the cross connecting rod 533, and finally enters the water inlet holes of the water inlet plate 5351. Driven by the high-pressure gas-liquid mixture, the telescopic nozzle 5352 overcomes the elastic force of the flushing spring 5354 and can slide and extend in the flushing housing 5353. The sliding of the telescopic nozzle 5352 drives the rotation and opening of the two closed wiper rods 531. The telescopic nozzle 5352 fully extends and sprays the high-temperature and high-pressure gas-liquid mixture. Cooperating with the rotation of the stirring and flushing device 53, the inner wall of the kettle body 1 and the spiral stirring device 52 are cleaned, and at the same time, the self-cleaning between the stirring and flushing devices 53 is completed. The high-temperature gas-liquid mixture will clean the high-melting-point residues remaining on the inner box stirring assembly 5 in the kettle body 1, and cooperate with the vibration of the stirring assembly 5 to shake off the dust on the inner box stirring assembly 5 in the kettle body 1, and the dust will be washed away together, so as to achieve the purpose of self-cleaning of the kettle body 1 and the stirring assembly 5.
