Description

Technical Field

[0001] This invention relates to the field of reaction vessel technology, and in particular to a rotary reaction device. Background Technology

[0002] Rotary reaction devices are reaction devices that need to be rotated during operation. They are core equipment used for material reactions in industries such as chemical, pharmaceutical, and food. For example, the equipment used in the production of lithium hexafluorophosphate, such as the "crystallization vessel" or "crystallization tank", has the core function of achieving the process goal of precipitating the solute from the solution and forming uniform crystals by precisely controlling the temperature, stirring and heat exchange process. The stirring is accomplished by the rotation of the vessel itself.

[0003] In existing rotary reactors, the inlet and outlet are usually located on the reactor itself. When feeding or discharging is required, separate pipes are needed to complete the feeding and discharging, resulting in low automation and inconvenient operation. Summary of the Invention

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Reference Figures 1 to 8 This invention provides a rotary reaction device, comprising a main body assembly 100, including a venting assembly 200 connected to the left side of the main body assembly 100, a material feeding assembly 300 inserted into the main body assembly 100, an anti-loosening assembly 400 fixed between the venting assembly 200 and the material feeding assembly 300, a first seal 500 connected to the left side of the venting assembly 200 and fixed to the venting assembly 200, a gas guiding assembly 600 connected to the left side of the first seal 500, a second seal 700 fixed to the left side of the gas guiding assembly 600, a double-end mechanical seal 800 connected to the left side of the second seal 700, and a material guiding assembly 900 connected to the left side of the double-end mechanical seal 800.

[0044] Specifically, such as Figure 2 , 3 In the middle, the gas guiding assembly 600 includes a housing 601 connected to the left side of the first seal 500, a drain pipe 602 fixed to the bottom of the housing 601 for gas phase draining, and a first pipe 603 fixed to the top of the housing 601 for connecting the exhaust port and the second nitrogen port through a tee fitting.

[0045] Furthermore, such as Figure 2 , 3 In the middle, the material guiding assembly 900 includes a tail cap 901 connected to the left side of the double-end mechanical seal 800, a liquid outlet pipe 902 fixed to the bottom of the tail cap 901, the liquid outlet pipe 902 is used to connect to the liquid outlet, and a second pipe 903 fixed to the top of the tail cap 901, the second pipe 903 is used to connect the first nitrogen port and the liquid inlet through a tee fitting.

[0046] When the rotary reactor is working, the rotation of the main component 100 will drive the aeration component 200 and the feed component 300 to rotate. During this process, the end of the aeration component 200 is inside the gas guiding component 600 and is sealed by the first seal 500 and the second seal 700. The end of the feed component 300 is inside the feed guiding component 900 and is sealed by the double-end mechanical seal 800.

[0047] Specifically, the main component 100 includes a vessel body 101, a connecting pipe 102 fixed to the inner left side wall of the vessel body 101, the inner right side wall of the connecting pipe 102 is conical, and the outer wall of the connecting pipe 102 is provided with a through groove 103, which communicates with the interior of the vessel body 101.

[0048] Specifically, such as Figure 6 In the process, the ventilation assembly 200 includes a connecting pipe 201 connected to the left side of the vessel body 101, and a ventilation pipe 202 connected to the left side of the connecting pipe 201. The ventilation pipe 202 is connected to the gas guiding assembly 600, the connecting pipe 201, the connecting pipe 102, and the vessel body 101, and can allow the gas guiding assembly 600 to pressurize gas into the vessel body 101 or discharge it. The inner wall of the left side of the ventilation pipe 202 is provided with a threaded groove 203.

[0049] Furthermore, such as Figure 7 In the process, the feeding assembly 300 includes a feeding tube 301 inserted into the connecting tube 102, a compression ring 302 fixed to the outer right side of the feeding tube 301, a sealing ring 303 and a conical ring 304 sleeved on the outer wall of the feeding tube 301 corresponding to the right side of the compression ring 302. Both the sealing ring 303 and the conical ring 304 are made of soft sealing material, and there are two sealing rings 303, each with a radius larger than the compression ring 302. A screw 305 is threaded to the outer wall of the feeding tube 301 corresponding to the right side of the conical ring 304. In use, by inserting the feeding tube 301 into the connecting tube 102, the feeding tube is driven... The sealing ring 303 and the conical ring 304 fit against the inner wall of the connecting pipe 102, and the sealing ring 303 is squeezed by the extrusion ring 302. Because the extrusion ring 302 is smaller than the sealing ring 303, the two sealing rings 303 will be squeezed outward during the extrusion process, and force will also be applied to the conical ring 304, so that the conical ring 304 fits against the conical surface of the inner wall of the connecting pipe 102, thereby forming a good sealing performance. When disassembling, pulling out the feed pipe 301 will drive the screw 305 to drive the conical ring 304 and the sealing ring 303, thereby removing the screw 305 to replace the sealing ring 303 and the conical ring 304.

[0050] Furthermore, such as Figure 8In the middle section of the outer wall of the feed pipe 301, the anti-loosening component 400 includes a fixed pipe 401 fixed to the middle section of the outer wall of the feed pipe 301. The right side of the fixed pipe 401 is adapted to the threaded groove 203. The outer wall of the fixed pipe 401 is provided with a slot 402. The outer wall of the fixed pipe 401 has multiple slots 402. The function of the slots 402 is to connect the air guide component 600 and the air pipe 202. A movable ratchet disc 403 slides on the right side of the fixed pipe 401. A fixed ratchet disc 404 is fixed on the left side of the air pipe 202. A spring 405 is fixed between the fixed pipe 401 and the movable ratchet disc 403. A pull ring 406 is fixed on the left side of the movable ratchet disc 403. In use, in the feed pipe During assembly 301, the fixed tube 401 is connected to the threaded groove 203 of the vent tube 202, thereby facilitating the subsequent compression of the sealing ring 303 and the conical ring 304 through the threaded pushing force. During this process, the fixed tube 401 drives the movable ratchet disc 403 to rotate. The movable ratchet disc 403 moves to the left due to the ratchet teeth of the fixed ratchet disc 404 and repeatedly compresses the spring 405. When the feed tube 301 is installed, the movable ratchet disc 403 will engage and fix the ratchet disc 404 due to the compression of the spring 405. Therefore, when the vessel body rotates, whether it rotates clockwise or counterclockwise, the feed tube 301 will not loosen.

[0051] During this process, the feed tube 301 is inserted into the connecting tube 102, which causes the sealing ring 303 and the conical ring 304 to adhere to the inner wall of the connecting tube 102. The extrusion ring 302 extrudes the sealing ring 303. Because the extrusion ring 302 is smaller than the sealing ring 303, the two sealing rings 303 are extruded outward during the extrusion process. Force is also applied to the conical ring 304, causing the conical ring 304 to adhere to the conical surface of the inner wall of the connecting tube 102, thereby forming a good sealing performance. When disassembling, pulling out the feed tube 301 will drive the screw 305 to drive the conical ring 304 and the sealing ring 303. The sealing ring 303 and the conical ring 304 can be replaced by removing the screw 305.

[0052] In summary, the main component 100, the feeding component 300, and the anti-loosening component 400 work together to facilitate the installation of the feeding pipe 301, provide good sealing performance, and prevent the feeding pipe 301 from loosening when the reactor body is operating in both forward and reverse directions.

[0053] The specific operation of the rotary reaction apparatus is as follows:

[0054] Liquid feeding process: Open the liquid inlet and simultaneously open the exhaust port, close the liquid outlet, nitrogen port 1, and nitrogen port 2. The material enters the material guiding component 900 through the second pipe 903 and enters the vessel body 101 through the material passage pipe 301 of the material passage component 300 to achieve feeding. At the same time, the original gas in the vessel body 101 enters the ventilation component 200 through the passage 103, passes through the connecting pipe 102, connecting pipe 201, and ventilation pipe 202 in sequence, and is discharged through the exhaust port of the first pipe 603.

[0055] Drainage process: Close the liquid inlet, exhaust outlet, nitrogen inlet No. 1, and nitrogen inlet No. 2, and at the same time open the drain outlet to drain the liquid remaining in the feed guide assembly 900 during the liquid inlet process.

[0056] Material reaction process control: Close the liquid inlet, liquid outlet, and exhaust outlet, open the second nitrogen port to charge nitrogen, and the nitrogen passes through the first pipe 603 of the gas guiding component 600, then through the vent pipe 202, connecting pipe 201, connecting pipe 102, and through channel 103, and finally enters the reactor body 101.

[0057] Liquid discharge process: The liquid inlet, nitrogen port 1, and exhaust port are opened simultaneously, and the liquid discharge port and nitrogen port 2 are opened. The nitrogen gas forces the material in the vessel body 101 into the feed pipe 301, and then the material is discharged from the liquid discharge port through the liquid discharge pipe 902 of the feed guide assembly 900.

[0058] Purging and drying process: Open nitrogen port 1 and exhaust port, close liquid inlet, liquid outlet and nitrogen port 2. Nitrogen gas enters the material passage pipe 301 of material passage component 300 through the second pipe 903 of material guide component 900 through nitrogen port 1, and then enters the vessel body 101 to purge and dry the vessel body 101. Afterwards, it returns through passage 103, passes through connecting pipe 102, connecting pipe 201 and vent pipe 202 in sequence, and is discharged through the exhaust port of first pipe 603.
