Description

Vertical high temperature coating reactor

Technical Field

The invention relates to the technical field of coating kettles, in particular to a vertical high-temperature coating kettle.

Background technique

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 radiated and heated by the heating equipment. When the temperature reaches the set value, the viscous liquid medium is evenly mixed and coated with the powder medium under the action of the stirring shaft.

The equipment used to produce the most negative electrode materials in the industry is horizontal coating kettle and vertical coating kettle. They are all welded by inner and outer spiral belts and shafts to form a stirring component for stirring and coating. The cleaning and maintenance of the vertical coating kettle is relatively difficult because the material accumulates in the kettle and needs to be emptied during cleaning. In addition, there may be dead corners inside the kettle that are difficult to reach, which increases the difficulty of cleaning. At the same time, due to its structural characteristics, the material in the vertical coating kettle often forms a natural accumulation in the kettle, which may cause the fluidity of the material to deteriorate, especially when dealing with materials with high viscosity and easy to agglomerate. Poor fluidity may lead to uneven reaction and affect product quality. Due to the high-temperature reaction of the coating kettle, the high-temperature flue gas generated is directly discharged, which will not only pollute the environment, but also cause energy waste. Therefore, there is a need on the market for an efficient and energy-saving coating kettle that can make the stirring more uniform and easy to clean.

The sealed bearing is a bearing structure and is provided with a sealing layer to prevent leakage of internal liquid; the upper spiral connecting rod and the spiral cross connecting rod are hollow rods.

Since 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 connecting rod, the second side bevel gear meshes with the second upper bevel gear, so that the second side bevel gear drives the spiral cross-link to rotate around its own central axis, and 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 that of the upper spiral connecting rod, and the lower spiral sleeve drives the spiral blades to rotate, and the rotation of the spiral blades drives the bottom raw materials to turn up, so as to avoid insufficient reaction caused by the sinking of materials to the bottom. and agglomeration; 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 a vortex, so that the material in the vortex cannot be fully stirred. At this time, the spiral blades rotate reversely in the center of the stirring and flushing device, causing the bottom raw materials to turn up and reversely hit the raw materials in the vortex. The raw materials collide with each other and destroy the vortex, so that the stirring is uniform, and the small agglomerates are dispersed during the collision and stirring, so that the reaction is more complete. When unloading, the control system controls the spiral blades to rotate in the opposite direction, and the spiral blades drive the finished product to rotate downward, so as to quickly complete the unloading and prevent the bottom unloading port from being blocked.

The rotation of the spiral cross-link drives the first side bevel gear at the other end to rotate, and 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-link to rotate, and the cross-link 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 materials and scrapes the inner wall of the kettle body, so that the viscous medium adhered to it is scraped off, and reacts with the powdered medium as the stirring occurs. The spiral ribbon blades between the flushing connecting pipes rotate to stir and turn over the raw materials, and destroy the vortex generated by the rotation of the spiral stirring device.

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 shell is installed on one side of the vibrating ring, the bottom end of the vibrating shell 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 shell, 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 shell, and the vibrating head passes through the vibrating spring.

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.

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.

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 steam flows from the heating water pipe into the steam chamber.

The working principle of the present invention is as follows: raw materials are added into the kettle body 1, the control system starts the driving component 3, the output end of the driving component 3 drives the upper spiral connecting rod 521 to rotate through the 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 wall scraping 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 wall scraping 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 to prevent dust from adhering to the inner wall of the kettle body 1 in the non-stirring area.

Since the upper spiral sleeve 522 and the second upper bevel gear 523 are both fixed and do not rotate, when the spiral cross-link 5210 rotates around the central axis of the upper spiral link 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-link 5210 to rotate around its own central axis, and 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 that of the upper spiral link 521, and 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 up to prevent them from sinking to the bottom, which would lead to incomplete reaction and agglomeration. At the same time, when the stirring and flushing device 53 rotates in one direction as a whole, it will drive the raw materials to rotate in a fixed direction to generate a vortex, so that the materials in the vortex cannot be fully stirred. At this time, the spiral blades 529 rotate in the reverse direction at the center of the stirring and flushing device 53, causing the bottom raw materials to turn up and hit the raw materials in the vortex in the reverse direction. The raw materials collide with each other to destroy the vortex, thereby making the stirring uniform. The small agglomerates are dispersed in the collision and stirring, thereby making the reaction more complete. When unloading, the control system controls the spiral blades 529 to rotate in the opposite direction, and the spiral blades 529 drive the finished product to rotate downward, so as to quickly complete the unloading and prevent the bottom unloading port from being blocked.

The rotation of the spiral cross link 5210 drives the first side bevel gear 514 at the other end to rotate, and 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, and the first lower bevel gear 517 drives the cross link 533 to rotate, and the cross link 533 drives the flushing connecting pipe 536 to rotate, and the flushing connecting pipe 536 drives the scraper rod 531 to rotate through the connecting baffle 534 and the end baffle 537, and the scraper rod 531 rotates while stirring the raw materials and scraping the inner wall of the kettle body 1, so that the viscous medium adhered to it is scraped off, and reacts with the powdered medium as stirring, and the spiral ribbon blades 532 between the flushing connecting pipe 536 rotate to stir and turn over the raw materials, and destroy the vortex generated by the rotation of the spiral stirring device 52.

The first upper bevel gear rotates on the wall scraper connecting rod 513, driving the vibration head 5121 on the top of the first bevel gear to rotate. The vibration head 5121 rotates and hits the fixed vibration scraper 5131 that does not rotate, generating vibration. At the same time, it is subjected to the impact force and slides and contracts along the vibration housing 5123. When the vibration head 5121 rotates past the vibration scraper 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, and this cycle continues. The first upper bevel gear 512 and the scraper connecting rod 513 are vibrated, and the scraper connecting rod 513 drives the scraper blade 518 to vibrate, so that the dust in the non-stirring area of the kettle body 1 is further vibrated and falls. The first upper bevel gear 512 transmits the vibration to the first side bevel gear 514 and the first lower bevel gear 517, and finally drives the stirring and flushing device 53 to vibrate. The vibration breaks up the lumps in the raw materials, thereby fully reacting. In the process of unloading, the finished products and unreacted powdered media stuck on the stirring and flushing device 53 are also shaken off.

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, and 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 steam flows from the heating water pipe 22 into the steam chamber 29. The water pump supplies water to the water tank to replenish the water in the heating water tank 23. When the unloading is completed, when the kettle body 1 is cleaned, the electric valve on the upper spiral connecting rod 521 is opened, and the water vapor, hot water and air are mixed by the gas-liquid stirring device, and 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 the action of high pressure.

The gas-liquid mixture flows from the upper spiral connecting rod 521 into the spiral cross connecting rod 5210, then flows into the flushing connecting pipe 536 through the cross connecting rod 533, and finally enters 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 sliding of the telescopic nozzle 5352 drives the two closed scraper rods 531 to rotate and open. The telescopic nozzle 5352 is fully extended and sprays the high-temperature and high-pressure gas-liquid mixture, and cooperates with the rotation of the stirring and flushing device 53 to complete the cleaning of the inner wall of the kettle body 1 and the spiral stirring device 52, and also completes the self-cleaning between the stirring and flushing devices 53. The high-temperature gas-liquid mixture will clean the high-melting-point residues remaining on the stirring component 5 in the kettle body 1, and cooperate with the vibration of the stirring component 5 to shake off the dust on the stirring component 5 in the kettle body 1 and be washed away together, thereby achieving the purpose of self-cleaning of the kettle body 1 and the stirring component 5.
