Description

Vertical high temperature coating autoclave Technical Field

[0001] This invention relates to the field of coating reactor technology, specifically a vertical high-temperature coating reactor. Background Technology

[0002] With the continuous development of the new energy industry, the quality of lithium battery raw materials is getting higher and higher, and the process of coating the negative electrode material at high temperature is a key step. After the raw materials enter the equipment, they are first radiated and heated at high temperature by heating equipment. When the temperature reaches the set value, the viscous liquid medium is uniformly mixed and coated with the powdered medium under the action of the stirring shaft.

[0003] The equipment commonly used in the industry for producing anode materials is the horizontal or vertical coating reactor. Both utilize a stirring component formed by welding internal and external spiral ribbons to a shaft for stirring and coating. Vertical coating reactors are relatively difficult to clean and maintain because material accumulates inside, requiring complete emptying during cleaning. Furthermore, the interior of the reactor may contain hard-to-reach corners, increasing the difficulty of cleaning. Additionally, due to its structural characteristics, material often naturally accumulates inside the vertical coating reactor, potentially leading to reduced material flowability, especially when processing highly viscous or easily agglomerated materials. Poor flowability can result in uneven reaction, affecting product quality. The high-temperature reaction in the coating reactor generates high-temperature fumes that are directly emitted, polluting the environment and wasting energy. Therefore, there is a need in the market for a high-efficiency, energy-saving coating reactor that allows for more uniform stirring and is easy to clean.

[0004] Summary of the Invention

[0005] The purpose of this invention is to provide a vertical high-temperature coating reactor to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A vertical high-temperature coating reactor includes a reactor body, a support frame installed at the bottom of the reactor body, a heat recovery device installed at the top of the reactor body, a drive assembly installed at the top of the reactor body, and a stirring assembly rotatably installed inside the reactor body. The output end of the drive assembly passes through the reactor 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 rinsing. 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 reactor body. A control system is installed inside the drive assembly, and the control system is used to control the entire coating reactor.

[0007] The mixing assembly includes a spiral agitator, a wall-scraping agitator, and a mixing and rinsing device. The mixing and rinsing device is rotatably connected to the vessel body and also rotatably connected to the output end of the drive assembly. The area from the top of the mixing and rinsing device to the bottom of the vessel body is a non-mixing zone. Dust will adhere to this non-mixing zone as the agitation progresses and the flue gas rises.

[0008] The wall-scraping agitator includes a first connecting shell, on which a wall-scraping connecting rod is mounted. A cross connecting rod is rotatably mounted at the bottom of the first connecting shell. Wall-scraping blades are mounted on the wall-scraping connecting rod. The first connecting shell is connected to both a spiral agitator and a mixing and rinsing device. The wall-scraping blades are used to scrape dust from the non-aggregated area. A sealing layer is provided at the mounting points of the wall-scraping connecting rod and the cross connecting rod with the first connecting shell.

[0009] The spiral mixing device includes a second connecting shell, a spiral cross link rotatably mounted on the side of the second connecting shell, an upper spiral sleeve rotatably mounted on the top of the second connecting shell, and a lower spiral sleeve rotatably mounted on the bottom of the second connecting shell. Spiral blades are mounted on the lower spiral sleeve. The spiral cross link is rotatably connected to the first connecting shell. Sealing layers are provided at the rotatable connections between the second connecting shell and the spiral cross link, the lower spiral sleeve, and the upper spiral sleeve.

[0010] The raw materials are added into the vessel, and the control system activates the drive assembly. The output of the drive assembly drives the upper spiral connecting rod to rotate via a pulley. The upper spiral connecting rod drives the spiral horizontal connecting rods on both sides and the lower spiral connecting rod at the bottom to rotate. The spiral horizontal connecting rod drives the entire wall scraping and stirring device and the stirring and rinsing device to rotate via the first connecting shell. This causes the stirring and rinsing device to rotate as a whole to stir the raw materials. The wall scraping and stirring device rotates to scrape and clean the non-stirring area from the top of the stirring and rinsing device to the bottom of the vessel, preventing dust from adhering to the inner wall of the vessel in the non-stirring area.

[0011] The upper spiral sleeve passes through the second connecting shell and is equipped with the second upper bevel gear. The lower spiral sleeve passes through the second connecting shell and is equipped with the second lower bevel gear. An upper spiral connecting rod is rotatably installed inside the upper spiral sleeve and is connected to the interior of the heat recovery device. A spiral transverse connecting rod passes through the second connecting shell and is equipped with the second side bevel gear. Sealed bearings are installed on both sides of the upper spiral connecting rod. The upper spiral connecting rod is rotatably connected to the spiral transverse connecting rod through the sealed bearings. The upper spiral connecting rod and the spiral transverse connecting rod are internally connected. The second upper bevel gear meshes with the second side bevel gear for transmission. The second side bevel gear meshes with the second lower bevel gear for transmission. A lower spiral connecting rod is rotatably installed inside the lower spiral sleeve and is connected to the bottom end of the upper spiral connecting rod.

[0012] The sealed bearing has a bearing structure and is equipped with a sealing layer to prevent internal liquid leakage; the upper helical connecting rod and the helical transverse connecting rod are hollow rods.

[0013] 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. This causes 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, which in turn 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 blades to rotate, and the rotation of the spiral blades causes the raw material at the bottom to turn upward, preventing the material from settling to the bottom and causing incomplete reaction. Meanwhile, when the entire stirring and rinsing device rotates in one direction, it will drive the raw materials to rotate in a fixed direction to generate a vortex, causing the materials in the vortex to not be fully stirred. At this time, the spiral blades rotate in the opposite direction at the center of the stirring and rinsing device, causing the raw materials at the bottom to turn up and collide with the raw materials in the vortex in the opposite direction. The collision between the raw materials breaks the vortex, thereby making the stirring uniform. Small lumps are broken up in the collision and stirring, thus making the reaction more complete. When feeding, the control system controls the spiral blades to rotate in the opposite direction. The spiral blades drive the finished product to rotate downward, quickly completing the feeding and preventing the bottom feeding port from being blocked.

[0014] A wall-scraping connecting pipe is installed inside the first connecting shell. A wall-scraping connecting rod passes through the first connecting shell and is rotatably mounted with a first upper bevel gear. A cross connecting rod passes through the first connecting shell and is mounted with a first lower bevel gear. A spiral transverse connecting rod passes through the first connecting shell and is mounted with a first side bevel gear. A sealed bearing is installed on the wall-scraping connecting pipe. The spiral transverse connecting rod is rotatably connected to the wall-scraping connecting rod through the sealed bearing. The cross connecting rod is rotatably connected to the bottom end of the wall-scraping connecting pipe through the sealed bearing. The wall-scraping connecting rod is connected to the top end of the wall-scraping connecting pipe. The wall-scraping connecting pipe is connected to the interior of the spiral transverse connecting rod and the cross connecting rod, respectively.

[0015] The rotation of the spiral horizontal connecting rod drives the first bevel gear at the other end to rotate. The rotation of the first 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 scraper rod to rotate through the connecting baffle and the end baffle. The scraper rod rotates while stirring the raw material and scraping the inner wall of the reactor, so that the sticky medium adhering to it is scraped off. As it is stirred, it reacts with the powdery medium. The spiral blades between the flushing connecting pipes rotate to stir and turn the raw material up, and disrupt the vortex generated by the rotation of the spiral stirring device.

[0016] A vibrating scraper is installed on the scraper connecting rod. A vibrating ring is installed on the top 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 baffle is installed on the vibrating head. A vibrating spring is installed between the spring baffle and the vibrating ring. The vibrating spring is located inside the vibrating housing. The vibrating head passes through the vibrating spring.

[0017] The first upper bevel gear rotates on the scraper connecting rod, driving the vibrating head at the top of the first bevel gear to rotate. The rotating vibrating head impacts the fixed, non-rotating vibrating scraper, generating vibration. Simultaneously, it slides and contracts along the vibrating shell due to the impact force. After the vibrating head passes the vibrating scraper, it is quickly reset by the elastic force of the vibrating spring. At the same time, the bottom of the vibrating head impacts the outer side of the vibrating ring, generating vibration. This cycle repeats, causing the first upper bevel gear and the scraper connecting rod to vibrate. The scraper connecting rod drives the scraper blades to vibrate, further shaking and dislodging the dust in the non-stirring zone of the vessel. The first upper bevel gear transmits the vibration to the first side bevel gear and the first lower bevel gear, ultimately driving the stirring and rinsing device to vibrate. The vibration breaks up the clumps in the raw materials, thus ensuring a full reaction. It also shakes off the finished product and unreacted powdery media adhering to the stirring and rinsing device during the feeding process.

[0018] The stirring and rinsing device includes a rinsing connecting pipe, which is internally connected to a cross connecting rod. Screw blades are installed between the rinsing connecting pipes. Several telescopic spray washing devices are installed on the rinsing connecting pipe, which are internally connected to the rinsing connecting pipe. A connecting baffle is installed on the rinsing 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 meshes with the telescopic spray washing device for transmission.

[0019] The telescopic spray washing device includes a washing housing, which is installed on a washing connecting pipe. A water inlet plate is installed on the washing housing and connected to the washing connecting pipe. The water inlet plate has a water inlet hole that communicates with the washing connecting pipe. A telescopic nozzle is slidably installed inside the washing housing. A washing spring is installed between the telescopic nozzle and the washing housing. The telescopic nozzle has threads and is driven by engaging with a scraper rod through the threads.

[0020] The gas-liquid mixture flows from the upper spiral connecting rod into the spiral cross connecting rod, then through the cross connecting rod into the flushing connecting pipe, and finally into 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 shell, and drives the two closed scraper rods to rotate and open. The telescopic nozzle fully extends and sprays the high-temperature and high-pressure gas-liquid mixture. In conjunction with the rotation of the stirring and flushing device, it completes the cleaning of the inner wall of the vessel 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 components inside the vessel, and in conjunction with the vibration of the stirring components, shake off the dust on the stirring components inside the vessel and wash it away, thereby achieving the purpose of self-cleaning of the vessel and the stirring components.

[0021] The heat recovery device includes an insulated outer shell, an inlet pipe, and an outlet pipe. The insulated outer shell is installed on the vessel body, and a heating water tank is installed inside the insulated outer shell. A heating water pipe is installed on the heating water tank and is connected to the inside of the heating water tank. A flue gas baffle is installed inside the heating water tank, and the heating water pipe passes through the flue gas baffle. The flue gas baffle and the top of the water tank form a sealed chamber. One end of the inlet pipe passes through the heating water tank and is connected to the inside of the sealed chamber, and the other end of the inlet pipe is connected to the inside of the vessel body. An outlet pipe is installed on the insulated outer shell and is located at the top of the sealed chamber. An expansion cap is installed at the top of the insulated outer shell, and a steam chamber is formed between the expansion cap and the flue gas baffle.

[0022] The heating water tank is connected to an external water pump, which supplies water to the tank. Electric valves are installed on the inlet pipe, outlet pipe, upper spiral connecting rod, and heating water pipe. The expansion top cover is made of expandable high-temperature resistant material, and the insulation shell is made of insulation material. The heating water tank has a built-in gas-liquid stirring device to mix water vapor and hot water in the tank. An air pump is connected to the outside of the steam chamber to pressurize the steam chamber.

[0023] When the high-temperature flue gas inside the reactor needs to be discharged, the control system opens the electric valve on the flue gas inlet pipe. The high-temperature flue gas enters the sealed chamber along the flue gas inlet pipe, where it 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 steam flows from the heating water pipe into the steam chamber. The water pump supplies water to the water tank to replenish the water in the heating water tank. After the material is unloaded, when cleaning the reactor, the electric valve on the upper spiral connecting rod is opened, and the gas-liquid stirring device mixes the steam, hot water, and air. The air pump is turned on to pressurize the steam chamber, and the gas-liquid mixture flows in from the upper spiral connecting rod under high pressure.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. The heat recovery device absorbs the heat of the high-temperature flue gas generated in the reaction inside the vessel, and uses the absorbed heat to heat cold water to generate steam and hot water. The steam, hot water and air are mixed to generate a high-temperature and high-pressure gas-liquid mixture. The gas-liquid mixture is used in conjunction with the rotation and vibration of the stirring component to complete the cleaning of the vessel and the self-cleaning of the stirring component itself, and to clean the high-melting-point residues and dust.

[0025] 2. The wall-scraping agitator scrapes away dust from the non-aggregated area, and vibration is used to shake the dust off. The spiral blades on the spiral agitator rotate counterclockwise in the center of the agitation and flushing device, causing the raw material at the bottom to turn up and collide with the raw material in the vortex. The collision between the raw materials breaks the vortex, making the agitation uniform and allowing small lumps to break up during the collision and agitation, preventing the raw material from clumping and making the reaction more complete. When feeding, the control system controls the spiral blades to rotate in the opposite direction. The spiral blades drive the finished product to rotate downward, quickly completing the feeding and preventing the bottom feed port from being blocked.

[0026] 3. The stirring and rinsing device completes overall stirring, rotational stirring, and raw material turning, preventing raw material agglomeration and making the raw material more uniformly mixed. At the same time, vibration is used to quickly break up agglomerates during stirring and vibration, improving production efficiency. The scraper rod scrapes the inner wall of the vessel to prevent raw materials from sticking to the inner wall of the vessel. The integrated telescopic spray washing device completes the cleaning of the vessel body and the spiral stirring device, as well as the cleaning of the stirring and rinsing device itself.

A flue gas outlet pipe 25 is provided on the insulation shell 21 and is located at the top of the sealed chamber 28. An expansion cap 26 is provided at the top of the insulation shell 21. A steam chamber 29 is formed between the expansion cap 26 and the flue gas baffle 27.

[0049] The heating water tank 23 is connected to an external water pump, which is used to supply water to the water tank. The inlet pipe 24, the outlet pipe, the upper spiral connecting rod 521, and the heating water pipe 22 are all equipped with electric valves. The expansion top cover 26 is made of expandable high-temperature resistant material, and the heat insulation shell 21 is made of heat insulation material. The heating water tank 23 is equipped with a gas-liquid stirring device, which is used to mix water vapor and hot water in the water tank. The steam chamber 29 is connected to an external air pump, which is used to pressurize the steam chamber 29.

[0050] The stirring and rinsing device 53 includes a rinsing connecting pipe 536, which is internally connected to the cross connecting rod 533. A screw ribbon blade 532 is installed between the rinsing connecting pipes 536. Several telescopic spray washing devices 535 are installed on the rinsing connecting pipes 536, and the telescopic spray washing devices 535 are internally connected to the rinsing connecting pipes 536. A connecting baffle 534 is installed on the rinsing connecting pipes 536. End baffles 537 are installed at both ends of the connecting baffle 534. A scraper rod 531 is rotatably installed between the end baffles 537. The scraper rod 531 meshes with the telescopic spray washing device 535 for transmission.

[0051] The telescopic spray washing device 535 includes a washing housing 5353, which is installed on a washing connecting pipe 536. A water inlet plate 5351 is installed on the washing housing 5353 and connected to the washing connecting pipe 536. The water inlet plate 5351 has a water inlet hole that communicates with the washing connecting pipe 536. A telescopic nozzle 5352 is slidably installed inside the washing housing 5353. A washing spring 5354 is installed between the telescopic nozzle 5352 and the washing housing 5353. The telescopic nozzle 5352 has threads and is driven by engaging with the scraper rod 531 through the threads.

[0052] The working principle of this invention is as follows: When the raw material is added into the vessel body 1, the control system activates the drive component 3. The output end of the drive component 3 drives the upper spiral connecting rod 521 to rotate via a belt pulley. The upper spiral connecting rod 521 drives the spiral horizontal connecting rods 5210 on both sides and the lower spiral connecting rod 528 at the bottom to rotate. The spiral horizontal connecting rods 5210 drive the entire wall scraping and stirring device 51 and the stirring and rinsing device 53 to rotate via the first connecting shell 511. This causes the stirring and rinsing device 53 to rotate as a whole to stir the raw material. The wall scraping and stirring device 51 rotates to scrape and clean the non-stirring area from the top of the stirring and rinsing device 53 to the bottom of the vessel body 1, preventing dust from adhering to the inner wall of the vessel body 1 in the non-stirring area.

[0053] Since both the upper spiral sleeve 522 and the second upper bevel gear 523 are fixed and do not rotate, when the spiral horizontal 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, causing the second side bevel gear 526 to drive the spiral horizontal 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, which in turn 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 bottom... The raw materials are turned upwards to prevent them from settling to the bottom, which would lead to incomplete reaction and clumping. At the same time, when the stirring and rinsing device 53 rotates in one direction, it will drive the raw materials to rotate in a fixed direction to generate a vortex. As a result, the materials in the vortex are not fully stirred. At this time, the spiral blades 529 rotate in the opposite direction at the center of the stirring and rinsing device 53, causing the raw materials at the bottom to turn upwards and collide with the raw materials in the vortex in the opposite direction. The collision between the raw materials breaks the vortex, thereby making the stirring uniform. Small clumps are broken up in the collision and stirring, thus making the reaction more complete. When feeding, the control system controls the spiral blades 529 to rotate in the opposite direction. The spiral blades 529 drive the finished product to rotate downwards, quickly completing the feeding and preventing the bottom feeding port from being blocked.

[0054] The rotation of the spiral cross link 5210 drives the first bevel gear 514 at the other end to rotate. The rotation of the first 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 link 533 to rotate. The cross link 533 drives the flushing connecting pipe 536 to rotate. The flushing connecting pipe 536 drives the scraper rod 531 to rotate through the connecting baffle 534 and the end baffle 537. The scraper rod 531 rotates while stirring the raw material and scraping the inner wall of the vessel body 1, so that the sticky medium adhering to it is scraped off. As it is stirred, it reacts with the powdery medium. The spiral blades 532 between the flushing connecting pipes 536 rotate to stir and turn the raw material up, and disrupt the vortex generated by the rotation of the spiral stirring device 52.

[0055] The first upper bevel gear rotates on the scraping connecting rod 513, driving the vibrating head 5121 at the top of the first bevel gear to rotate. The rotating vibrating head 5121 impacts the fixed, non-rotating vibrating scraper 5131, generating vibration. Simultaneously, it is subjected to the impact force and slides and retracts along the vibrating housing 5123. After the vibrating head 5121 rotates past the vibrating scraper 5131, it is subjected to the elastic force of the vibrating spring 5124, causing it to quickly return to its original position. At the same time, during the return, the bottom of the vibrating head 5121 impacts the outer side of the vibrating ring 5122, generating vibration. This cycle continues. The first upper bevel gear 512 and the scraper rod 513 vibrate, and the scraper rod 513 drives the scraper blade 518 to vibrate, which further vibrates the dust in the non-stirring zone of the vessel body 1 and causes it to fall. The first upper bevel gear 512 transmits the vibration to the first side bevel gear 514 and the first lower bevel gear 517, which ultimately drives the stirring and rinsing device 53 to vibrate. The vibration breaks up the clumps in the raw materials, thereby allowing for a full reaction. It also shakes off the finished products and unreacted powdery media that are stuck to the stirring and rinsing device 53 during the feeding process.

[0056] When the high-temperature flue gas inside the vessel 1 needs to be discharged, the control system opens the electric valve on the inlet pipe 24, allowing the high-temperature flue gas to enter the sealed chamber 28 along the 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 steam flows from the heating water pipe 22 into the steam chamber 29. The water pump supplies water to the water tank, replenishing the water in the heating water tank 23. After the material is unloaded, when cleaning the vessel 1, the electric valve on the upper spiral connecting rod 521 is opened, and the steam, hot water, and air are mixed using a gas-liquid stirring device. The air pump is turned on to pressurize the steam chamber 29, and the gas-liquid mixture flows in from the upper spiral connecting rod 521 under high pressure.

[0057] The gas-liquid mixture flows from the upper spiral connecting rod 521 into the spiral cross connecting rod 5210, then through the cross connecting rod 533 into the flushing connecting pipe 536, and finally into the water inlet hole of the water inlet plate 5351. Under the push of 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 shell 5353. The telescopic nozzle 5352 slides and drives the two closed scraper rods 531 to rotate and open. The telescopic nozzle 5352 fully extends and sprays the high-temperature and high-pressure gas-liquid mixture. With the rotation of the stirring and flushing device 53, the inner wall of the vessel body 1 and the spiral stirring device 52 are cleaned. At the same time, the self-cleaning between the stirring and flushing devices 53 is also completed. The high-temperature gas-liquid mixture will clean the high-melting-point residues remaining on the stirring assembly 5 inside the vessel body 1. With the vibration of the stirring assembly 5, the dust on the stirring assembly 5 inside the vessel body 1 is shaken off and washed away, thereby achieving the purpose of self-cleaning of the vessel body 1 and the stirring assembly 5.
