Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to an o-fluorotoluene production synthesis reaction vessel that can be automatically cleaned. Background Technology

[0002] o-Fluorotoluene, a fluorinated aromatic compound, is a key intermediate in the pharmaceutical, pesticide, dye, and liquid crystal material industries. Its synthesis typically involves using fluorobenzene and methylating agents as raw materials, and preparing it through Friedel-Crafts alkylation reactions in the presence of catalysts (such as anhydrous aluminum trichloride), or through diazotization and fluorination reactions of o-toluidine. These reactions often require high-pressure reactors. Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, medical, and food industries as pressure vessels for chemical reactions. After use, the interior of the reactor generally needs to be cleaned. However, current methods mostly rely on manual scrubbing with brushes, which is ineffective at cleaning the inner walls, resulting in poor cleaning quality, time-consuming and labor-intensive cleaning, and inconvenience. Utility Model Content

[0003] The purpose of this invention is to provide an o-fluorotoluene production synthesis reactor that can be automatically cleaned, so as to solve the problems of inconvenient and inefficient cleaning of the reactor after use as mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an o-fluorotoluene production synthesis reactor capable of automatic cleaning, comprising a support storage tank, a top cover being snapped onto the outer surface of the support storage tank, a discharge solenoid valve being installed through the outer surface of the support storage tank at the end away from the top cover, a drive motor being fixedly installed on the outer surface of the top cover, a rotating shaft being rotatably installed on the outer surface of the top cover and connected to the drive motor, and the drive motor, rotating shaft and top cover being concentrically designed, a rotating disk being rotatably installed inside the support storage tank, and a scraper and a brush being fixedly installed on the outer surface of the rotating disk, respectively, and a rotating mechanism being provided between the support storage tank and the rotating disk.

[0005] Preferably, the rotating mechanism includes: a flywheel, which is inserted and installed on the outer surface of the rotating disk, and the rotating disk and the flywheel are concentrically designed; a rack is fixedly installed on the outer surface of the rotating shaft, and the rack is inserted and connected to the flywheel.

[0006] By adopting the above technical solution, when the drive motor drives the rotating shaft to rotate forward via the flywheel, it can drive the stirring blades to stir the raw materials stored in the support storage tank. When the drive motor drives the rotating shaft to rotate in reverse, the internal parts of the flywheel will engage and drive the rotating disk to rotate. This allows the inside of the support storage tank to be cleaned by rotating in reverse, and to rotate forward when cleaning is not required. This greatly extends the service life of the scraper and brush, significantly reduces the maintenance cycle and frequency, and improves the durability of the scraper and brush.

[0007] Preferably, stirring blades are respectively installed and fixed on the outer surface of the rotating shaft, and the stirring blades are fixed to the rotating shaft with screws.

[0008] The above technical solution allows for easy installation and disassembly of the mixing blades, facilitating subsequent comprehensive cleaning and maintenance / replacement.

[0009] Preferably, the drive motor and the rotating shaft are connected by a coupling, and a positioning sleeve is installed through the outer surface of the rotating shaft. The outer surface of the positioning sleeve is in contact with the outer surface of the rotating shaft. A bolt is threaded on the outer surface of the positioning sleeve, and the bolt on the outer surface of the positioning sleeve is in contact with the outer surface of the rotating shaft. The outer surface of the positioning sleeve is in contact with the inner ring of the flywheel.

[0010] By adopting the above technical solution, the position of the flywheel can be fixed by the positioning bushing, so that the flywheel can be firmly engaged with the rotating disk. When disassembly and maintenance are required, the positioning bushing can be loosened and the stirring blades can be removed. At the same time, the coupling between the drive motor and the rotating shaft can be disassembled, so that the support storage tank and the top cover can be completely disassembled and separated, which facilitates installation, disassembly and maintenance.

[0011] Preferably, the top cover and the support storage tank are connected and fixed with bolts, and the support storage tank is in close contact with the outer surface of the top cover, and the outer surface of the top cover is provided with a feed port.

[0012] Using the above technical solution, the support storage tank and the top cover can be disassembled, allowing the support storage tank to be separated from the top cover, and enabling deep cleaning when changing the type of reaction material.

[0013] Preferably, the rotating shaft has a through cavity, and the outer surface of the rotating shaft has through holes that pass through the through cavity. The outer surface of the top cover has a feeding and dispersing cavity that is connected to the through cavity. A cleaning agent solenoid valve is fixedly installed on the outer surface of the top cover and is connected to the feeding and dispersing cavity. A diversion cavity is installed through the outer surface of the rotating shaft and is fixed to the rotating shaft with screws. A flushing and diversion mechanism is provided between the diversion cavity and the rotating shaft.

[0014] By adopting the above technical solution, the cleaning agent can be introduced into the feed dispersion chamber through the cleaning agent solenoid valve, allowing the cleaning agent to enter the distribution chamber through the connecting chamber, and then be evenly sprayed into the support storage tank through the spray nozzle. This facilitates the injection of the cleaning agent into the support storage tank for reaction and dissolution during cleaning. Combined with the rotation and brushing of the support storage tank by the scraper and brush, the cleaning effect and processing efficiency are greatly improved.

[0015] Preferably, the flushing and diversion mechanism includes: a sealing ring, which is respectively engaged and installed on the outer surfaces of both ends of the diversion cavity, and the outer surface of the diversion cavity is in close contact with the outer surface of the sealing ring, and the outer surface of the sealing ring is in close contact with the outer surface of the rotating shaft, the through hole of the rotating shaft is connected to the diversion cavity, and the outer surface of the diversion cavity is uniformly provided with spray nozzles, and the orientation of the spray nozzles is different.

[0016] By adopting the above technical solution, the gap between the distribution chamber and the rotating shaft can be sealed by the sealing ring, preventing the injected cleaning agent from leaking out from other places. It can be easily and quickly assembled and disassembled, and can maintain the pressure of the cleaning agent sprayed from the spray nozzle. Furthermore, by adjusting the direction of the spray nozzle, the sprayed cleaning agent can be sprayed in different directions into the bracket storage tank. In conjunction with the rotation of the rotating shaft, the cleaning agent can be rotated and sprayed into the interior of the bracket storage tank, greatly improving the spraying quality of the cleaning agent.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the automatically cleanable o-fluorotoluene production synthesis reactor:

[0018] 1. After the o-fluorotoluene has been mixed and reacted in the support storage tank, the discharge solenoid valve can be opened to discharge the mixed o-fluorotoluene into the finished product tank. Then, the cleaning agent can be injected into the support storage tank, and the rotating shaft can be rotated in the reverse direction by the reverse rotation of the drive motor, so that the flywheel can drive the rotating disk to rotate together, so that the scraper and brush can rotate and scrub and clean the inner wall of the support storage tank, ensuring the cleanliness of the support storage tank inside when used next time, so that the quality will not be affected by residues when o-fluorotoluene is prepared again.

[0019] 2. The forward rotation of the drive motor can drive the rotating shaft to rotate. In conjunction with the characteristics of the flywheel, the stirring blades can rotate to stir and prepare o-fluorotoluene. The reverse rotation of the drive motor can drive the rotating shaft to rotate in reverse, so that the rack can drive the flywheel to rotate in reverse, and the rotating disk can rotate together with the scraper and brush. By controlling the forward and reverse rotation of the drive motor, the operating state of the scraper and brush can be controlled, so that the scraper and brush can be used when needed, which greatly reduces the wear of the scraper and brush and improves the service life and maintenance cycle of the scraper and brush.

[0020] 3. When cleaning the inside of the support storage tank, the cleaning agent can be injected into the feeding dispersion chamber through the cleaning agent solenoid valve, and then into the distribution chamber through the connecting chamber. This allows the cleaning agent to be dispersed to each spray nozzle and sprayed out from the nozzle. The cleaning agent is sprayed into different directions inside the support storage tank by the different directions of the spray nozzles. The rotation of the rotating shaft drives the distribution chamber to rotate as well, allowing the cleaning agent to be sprayed evenly into the inside of the support storage tank, greatly improving the cleaning and rinsing effect. Afterwards, injecting clean water into the cleaning agent solenoid valve will rinse the inside of the support storage tank, greatly improving the rinsing and cleaning effect and efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: an o-fluorotoluene production synthesis reactor capable of automatic cleaning, including a support storage tank 1, a top cover 2 fitted onto the outer surface of the support storage tank 1, a discharge solenoid valve 18 installed through the outer surface of the support storage tank 1 away from the top cover 2, a drive motor 3 fixedly installed on the outer surface of the top cover 2, the top cover 2 and the support storage tank 1 are connected and fixed by bolts, and the outer surfaces of the support storage tank 1 and the top cover 2 are tightly fitted, a feed port is opened on the outer surface of the top cover 2, a rotating shaft 4 is rotatably installed on the outer surface of the top cover 2, and the rotating shaft 4 is connected to the drive motor 3, and the drive motor 3, the rotating shaft 4 and the top cover 2 are concentrically designed, stirring blades 5 are respectively inserted and fixed on the outer surface of the rotating shaft 4, and the stirring blades 5 are fixed to the rotating shaft 4 by screws, a rotating disk 6 is rotatably installed inside the support storage tank 1, and a scraper 7 and a brush 8 are respectively fixedly installed on the outer surface of the rotating disk 6.

[0030] First, after the o-fluorotoluene is stirred and reacted inside the support storage tank 1 by the stirring blades 5, the discharge solenoid valve 18 is opened and discharged into the finished product tank. Then, the discharge solenoid valve 18 is closed and the pipeline is connected to the wastewater treatment pipeline. Subsequently, the drive motor 3 rotates in the reverse direction, driving the rotating shaft 4 to rotate. The rotating shaft 4 drives the flywheel 12 to rotate together through the rack 14, causing the rotating disk 6, which is engaged with the flywheel 12, to rotate in the same direction. The rotation of the rotating disk 6 causes the scraper 7 and the brush 8 to rotate together. The scraper 7 can scrape and wash the inside of the support storage tank 1, and the brush 8 can brush and wash the stubborn stains inside the support storage tank 1. This makes it easy to clean the inside of the support storage tank 1, greatly improving the cleaning and washing efficiency and ensuring the cleanliness of the inside of the support storage tank 1. This ensures that the quality will not be affected by the residue inside the support storage tank 1 when o-fluorotoluene is prepared again.

[0031] A rotating mechanism is provided between the storage bucket 1 and the rotating disk 6. The rotating mechanism includes a flywheel 12, which is inserted and installed on the outer surface of the rotating disk 6. The rotating disk 6 and the flywheel 12 are concentrically designed. A rack 14 is fixedly installed on the outer surface of the rotating shaft 4, and the rack 14 is inserted and connected to the flywheel 12.

[0032] Secondly, when it is not necessary to clean the inside of the support storage tank 1, simply drive the motor 3 to rotate in the forward direction, which will drive the rotating shaft 4 to rotate. The rotating shaft 4 can then drive the stirring blades 5 to stir and prepare o-fluorotoluene in the support storage tank 1. When it is necessary to clean the residue in the support storage tank 1, simply drive the motor 3 to rotate in the reverse direction, which will drive the flywheel 12 to rotate through the reverse rotation of the rotating shaft 4 and the rack 14. Through the engagement of the internal parts of the flywheel 12, the flywheel 12 drives the rotating disk 6 to rotate. The forward and reverse rotation of the drive motor 3 can control the movement of the scraper 7 and the brush 8, so that the scraper 7 and the brush 8 will not rotate continuously and cause wear, which greatly improves the service life of the scraper 7 and the brush 8 and reduces the maintenance cycle of the scraper 7 and the brush 8.

[0033] The drive motor 3 is connected to the rotating shaft 4 by a coupling, and a positioning sleeve 13 is installed through the outer surface of the rotating shaft 4. The outer surface of the positioning sleeve 13 is in contact with the outer surface of the rotating shaft 4. A bolt is threaded on the outer surface of the positioning sleeve 13, and the bolt on the outer surface of the positioning sleeve 13 is in contact with the outer surface of the rotating shaft 4. The outer surface of the positioning sleeve 13 is in contact with the inner ring of the flywheel 12.

[0034] Remove the coupling between the drive motor 3 and the rotating shaft 4, and remove the bolts between the support storage tank 1 and the top cover 2. Then, the support storage tank 1 and the top cover 2 can be separated, and the positioning bushing 13 can be exposed and removed. Then, the flow divider 15 and the stirring blade 5 can be removed and separated. This facilitates the deep cleaning and scrubbing of the inside and parts of the support storage tank 1, and makes maintenance, replacement and disassembly convenient.

[0035] A connecting cavity 9 is provided through the interior of the rotating shaft 4. Through holes are respectively opened on the outer surface of the rotating shaft 4, and the through holes of the rotating shaft 4 pass through the connecting cavity 9. A feeding dispersion cavity 10 is opened on the outer surface of the top cover 2, and the feeding dispersion cavity 10 is connected to the connecting cavity 9. A cleaning agent solenoid valve 11 is fixedly installed on the outer surface of the top cover 2, and the cleaning agent solenoid valve 11 is connected to the feeding dispersion cavity 10. A diversion cavity 15 is installed through the outer surface of the rotating shaft 4, and the diversion cavity 15 is fixed to the rotating shaft 4 with screws. A flushing and diversion mechanism is provided between the diversion cavity 15 and the rotating shaft 4. The flushing and diversion mechanism includes a sealing ring 16, which is respectively engaged and installed on the outer surfaces of both ends of the diversion cavity 15. The outer surface of the diversion cavity 15 is in close contact with the outer surface of the sealing ring 16, and the outer surface of the sealing ring 16 is in close contact with the outer surface of the rotating shaft 4. The through hole of the rotating shaft 4 is connected to the diversion cavity 15. Spray nozzles 17 are evenly opened on the outer surface of the diversion cavity 15, and the orientation of the spray nozzles 17 is different.

[0036] Furthermore, when cleaning is required, the cleaning agent is simply injected into the feed dispersion chamber 10 through the cleaning agent solenoid valve 11, allowing the cleaning agent to move along the connecting chamber 9 inside the rotating shaft 4, and then into the distribution chamber 15. The distribution chamber 15 and the rotating shaft 4 are sealed by the sealing ring 16, allowing the cleaning agent to be injected into the distribution chamber 15 and sprayed into the bracket storage tank 1 through the spray nozzle 17. At the same time, the different orientations of the spray nozzle 17 and the rotation of the distribution chamber 15 driven by the rotating shaft 4 allow the cleaning agent to be sprayed more evenly inside the bracket storage tank 1. Combined with the scraper 7 and brush 8 to scrub the bracket storage tank 1, the residue inside the bracket storage tank 1 can be cleaned by the cleaning agent. The scrubbing of the scraper 7 and brush 8 makes the inside of the bracket storage tank 1 cleaner, greatly improving the convenience and practicality of cleaning the bracket storage tank 1.

[0037] Working principle: After o-fluorotoluene is prepared, it can be discharged into the finished product tank through the discharge solenoid valve 18. Then, the discharge solenoid valve 18 can be closed again, and the cleaning agent solenoid valve 11 can be opened to inject the cleaning agent into the feed dispersion chamber 10 and into the diversion chamber 15 through the connecting chamber 9. The cleaning agent is sprayed in different directions through the spray nozzle 17. Then, the reverse rotation of the drive motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the rotating disk 6 to rotate together through the rack 14, so that the scraper 7 and the brush 8 can rotate together to clean the inside of the support storage tank 1. Then, clean water is injected through the cleaning agent solenoid valve 11, and the clean water can be sprayed out through the cleaning agent solenoid valve 11, the feed dispersion chamber 10, the connecting chamber 9, and the diversion chamber 15 to rinse away the cleaning agent. The wastewater can be discharged through the discharge solenoid valve 18, which greatly improves the efficiency and quality of cleaning the support storage tank 1 and improves the convenience of use.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
