Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4This utility model provides a high-safety alkylation reaction apparatus technical solution: It includes a tank body 1, with a top cover 101 on the outer top surface of the tank body 1. A feed cover 4 is rotatably connected to the right end of the top surface of the top cover 101. The feed cover 4 is opened by holding the handle, and then the material to be alkylated is poured into the tank body 1. The feed cover 4 is then closed. A discharge pipe 401 is fixedly and continuously connected to the outer bottom surface of the tank body 1. The valve on the discharge pipe 401 is opened to open the discharge pipe. 401. After that, the material that has completed the alkylation reaction can be discharged. At the same time, the top cover 101 is fixed to the tank body 1 by bolts and threads. The threaded connection facilitates disassembly, maintenance and replacement in the future. A limit ring 5 is fixed to the bottom of the outer wall of the tank body 1. Support rods 501 are fixed to the four corners of the outer bottom surface of the limit ring 5. The outer bottom surface of the four support rods 501 is fixed to the load-bearing blocks 502. The limit ring 5, support rods 501 and load-bearing blocks 502 can achieve the effect of supporting and fixing the tank body 1.

[0027] A rotating shaft 102 is rotatably mounted inside the tank body 1 and on the outer bottom surface of the top cover 101. A wall-scraping assembly 2 for scraping the inner wall of the tank body 1 is provided outside the rotating shaft 102. The wall-scraping assembly 2 includes a block 201 fixedly mounted on the outer wall of the rotating shaft 102. A square cavity 202 is formed inside the block 201. Cylindrical tubes 203 are fixed to the outer walls of both sides of the block 201. U-shaped plates 204 are fixedly mounted on the outer walls of both cylinders 203. Scraper blades 205 are provided on the inner sides of both U-shaped plates 204. The top end of the rotating shaft 102 extends rotatably to the outer top surface of the top cover 101, and a gear 1 is fixed to its outer wall. A connecting rod 207 is rotatably mounted on the outer top surface of the top cover 101 and outside the rotating shaft 102. A gear 208 is fixed to the outer wall of the connecting rod 207. Gear 206 and gear 208 are meshed together. Gear 1 and gear 208 are meshed together. A drive motor 209 is fixed on the outer top surface of the top cover 101 and at the corresponding position of the connecting rod 207. The output end of the drive motor 209 is fixed to the connecting rod 207. By controlling and starting the drive motor 209, the connecting rod 207 is driven to rotate gear 208. Under the meshing connection characteristics of the gears, gear 1 is driven to rotate the rotating shaft 102. This not only fully stirs and mixes the material inside the tank 1, but also cleans the material adhering to the inner wall of the tank 1. Similarly, when cleaning later, after injecting cleaning water into the tank 1, the cleaning is carried out in the same way. This not only reduces the labor intensity of workers, but also improves work efficiency and reaction effect, and increases practicality.

[0028] A circular hole 3, communicating with the square cavity 202, is opened on the outer top surface of the rotating shaft 102. A circular rod 301 is rotatably mounted inside the circular hole 3. One end of the circular rod 301 extends into the interior of the square cavity 202 and a bevel gear 302 is fixed to its outer wall, while the other end extends to the outer top surface of the rotating shaft 102 and a knob 303 is fixed thereon. Circular rods 304 are rotatably mounted on the inner walls of both the left and right sides of the square cavity 202. A bevel gear 305 is fixed to one end of each of the two circular rods 304, while the other end... The ends extend into the inner sides of the two cylinders 203, and the outer walls are threaded. Simultaneously, the external threads of the two cylindrical rods 304 are fitted with sleeves 306. The opposite ends of the two sleeves 306 are fixedly connected to the two scrapers 205. The first bevel gear 302 and the two second bevel gears 305 mesh with each other. Sliding rods 307 are symmetrically installed on the corresponding outer walls of the two scrapers 205. The corresponding ends of the two pairs of sliding rods 307 slide and extend to the corresponding outer walls of the two U-shaped plates 204. The rotary knob 303 can drive the first round rod 301 to rotate the first bevel gear 302 inside the square cavity 202 (after turning, the first round rod 301 is locked by the shaft locking device installed on the outer top surface of the rotating shaft 102). Under the meshing connection characteristics of the first bevel gear 302, it synchronously drives the two second bevel gears 305 to drive the two second round rods 304 to rotate inside the two cylinders 203 (the threads on the two second round rods 304 run in opposite directions), and drives the two cylinders 203 through the threaded connection characteristics. The circular sleeves 306 move relative to each other inside the cylinder 203, either moving away from each other or moving closer to each other. This allows the scraper 205 to move out from the inside of the U-shaped plate 204 and come into contact with the inner wall of the tank 1 of different sizes and specifications, thus enabling cleaning and further improving practicality. At the same time, the two circular sleeves 306 are fitted with accordion sleeves on the outside. The two ends of the accordion sleeves are fixedly connected to the scraper 205 and the U-shaped plate 204 respectively, thereby preventing materials and water from entering the inside of the cylinder 203 during use and causing any impact.

[0029] The working principle of this utility model is as follows: When in use, the material to be alkylated is first poured into the tank 1 through the feed cover 4, and then the drive motor 209 is started to drive the connecting rod; 207 drives the gear two to rotate, and drives the gear one to drive the rotating shaft 102 to rotate, thereby not only fully stirring and mixing the material inside the tank 1, but also cleaning the material adhering to the inner wall of the tank 1.

[0030] At the same time, turning the knob 303 drives the first round rod 301 to drive the first bevel gear 302 to rotate inside the square cavity 202, and simultaneously drives the two second bevel gears 305 to drive the two second round rods 304 to rotate inside the two cylinders 203, thereby driving the two round sleeves 306 to move relative to each other inside the cylinders 203, thereby pushing the scraper 205 to clean the inner wall of the tank 1 of different sizes and specifications.

[0031] At the same time, open the discharge pipe 401 to discharge the material.

[0032] Finally, pour the cleaning water into tank 1 and follow the steps above to complete the cleaning operation.

[0033] It should be noted that the tank 1 is an alkylation reaction tank (alkylation reaction tanks are conventional instruments, and their working principle will not be described in detail). All electrical components mentioned in the text are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.

[0034] All standard parts used can be purchased from the market, and can be customized according to the instructions and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology, and the structure and principle of the components known to those skilled in the art can be known by those skilled in the art through technical manuals or conventional experimental methods.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
