Description

Technical Field

[0001] The utility model relates to the technical field of hydrolysis reactors, in particular to a continuous production hydrolysis reactor. Background Art

[0002] A hydrolysis reactor is a special reaction vessel used for hydrolysis reactions. Hydrolysis is a type of chemical reaction, which usually refers to the process of decomposing chemical substances into simpler substances by adding water molecules. In a hydrolysis reactor, the substance to be hydrolyzed and an appropriate amount of water are usually added, and the reaction is promoted by controlling parameters such as temperature, pressure and stirring speed. Hydrolysis reactors are widely used in the chemical industry, such as organic synthesis reactions, drug synthesis and food processing.

[0003] The Chinese patent authorization announcement number is CN219849480U, and the name is a hydrolysis reactor, which includes a reactor body, an inner cylinder is installed inside the reactor body, a motor is installed on the top of the reactor body, and the output end of the motor is connected to a stirring shaft extending into the reactor body. A rotating assembly and a pressure relief assembly are respectively arranged above the reactor body. The rotating assembly includes a movable shaft and a movable groove arranged above the reactor body and a driving gear sleeved on the outside of the stirring shaft. By providing a rotating assembly, when the stirring shaft rotates, it drives the driving gear to rotate, and then drives the driven gear to rotate. After the driven gear rotates, it drives the gear ring to rotate. The rotation of the gear ring drives the stirring frame to rotate. Since the rotation direction of the stirring frame is opposite to that of the stirring shaft, the stirring frame and the stirring shaft can fully stir the hydrolyzate. At the same time, this method does not require the addition of an additional driving mechanism, so as to achieve energy-saving effect.

[0004] The shortcomings of the above-mentioned prior art solutions are: although the above-mentioned solution can make the stirring frame and the stirring shaft move in opposite directions without adding an additional driving mechanism, so that the stirring is more sufficient, during the hydrolysis process, the water inside the reactor will evaporate and adhere to the top wall of the reactor body, causing the concentration of the reactants after hydrolysis to be greater than the original calculated concentration. The staff will subsequently need to dilute the concentration, which increases the operating burden of the staff. In addition, the evaporated water vapor carries the material and adheres to the top wall of the reactor body, which is also likely to cause corrosion to the reactor body, reducing the service life of the device.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-4 As shown, a continuous production hydrolysis reactor comprises a reactor 1, an explosion-proof inner tank 2 is arranged inside the reactor 1, and a water bath cover 3 is arranged on the outer side of the explosion-proof inner tank 2;

[0024] The explosion-proof inner tank 2 is provided with a rotating rod 4 for rotation inside. Four groups of stirring paddles 5 are connected to the outer side of the bottom end of the rotating rod 4 at intervals. A water injection groove 6 is provided through the top of the rotating rod 4. Four groups of connecting grooves 7 communicating with the water injection groove 6 are provided at intervals on the outer side of the top end of the rotating rod 4. A sealing sleeve 8 is provided on the outer side of the top end of the rotating rod 4. Four groups of supporting tubes 9 distributed at intervals are connected to the outer side of the sealing sleeve 8. A circular tube 10 is connected to one end of the supporting tube 9. A nozzle 11 is connected to the top of the circular tube 10. The top of the rotating rod 4 can be rotatably connected to an external water pipe, so that water is input into the supporting tube 9 through the water injection groove 6 and the connecting groove 7, and then converged into the circular tube 10 through the supporting tube 9. The nozzle 11 provided on the circular tube 10 can spray the top wall of the explosion-proof inner tank 2 Sprinkle, when the rotating rod 4 rotates, it can also drive the nozzle 11 to rotate and spray. The tops of the two groups of support tubes 9 are connected with arc scrapers 12. The inner wall of the sealing sleeve 8 is penetrated with a through hole 13 for connecting the connecting groove 7 and the support tube 9. When the hydrolysis reaction is carried out inside the material device, the generated water vapor will carry the material and adhere to the top wall of the kettle body. At this time, the rotating rod 4 can drive the support tube 9 to rotate, so that the arc scraper 12 can scrape the water vapor attached to the top wall of the explosion-proof inner tank 2. The top of the arc scraper 12 fits with the top wall of the explosion-proof inner tank 2, and the upwardly protruding top also forms a drainage effect when scraping off the water vapor. When the top wall of the explosion-proof inner tank 2 needs to be cleaned, the top of the rotating rod 4 is rotatably connected to the external water pipe.

[0025] The top end of the rotating rod 4 passes through the explosion-proof inner tank 2 and the top wall of the reactor 1 in sequence, and a power mechanism for driving the rotating rod 4 to rotate is arranged above the reactor 1, and the power mechanism includes a motor and a reduction gear box. The reduction gear set arranged inside the reduction gear box is meshed with the rotating rod 4, so that the motor drives the reduction gear set arranged inside the reduction gear box to rotate, thereby causing the rotating rod 4 to rotate, stirring the material inside the device, so that the hydrolysis reaction can be carried out more fully.

[0026] Four groups of material pipes 14 are arranged through the top of the reactor 1, and the bottom ends of the material pipes 14 are communicated with the top of the explosion-proof inner tank 2. Different types of materials can be injected into the interior of the explosion-proof inner tank 2 at different stages through the material pipes 14, so as to realize continuous production. A discharge pipe 15 is arranged at the bottom of the reactor 1, and the input end of the discharge pipe 15 is communicated with the bottom of the explosion-proof inner tank 2. When the reaction of various materials inside the device is completed, the reactants can be discharged through the discharge pipe 15.

[0027] An outer sleeve 16 is connected to the top central area of ​​the reactor 1. The outer sleeve 16 is located outside the rotating rod 4. The outer sleeve 16 not only protects the rotating rod 4, but also supports the power mechanism, thereby ensuring the stability of the power mechanism during operation.

[0028] A hot water pipe 17 is connected to one side of the reactor 1, and the output end of the hot water pipe 17 is communicated with one side of the water bath cover 3. A reflux pipe 18 is connected to the other side of the reactor 1, and the output end of the reflux pipe 18 is communicated with the other side of the water bath cover 3. The reflux pipe 18 is located above the hot water pipe 17. When the device needs to be heated, the external pipeline of the hot water pipe 17 injects hot water into the water bath cover 3. Since the hot water pipe 17 is lower than the reflux pipe 18, the water body can fully heat the explosion-proof inner tank 2 in a water bath and then be discharged through the reflux pipe 18.

[0029] The bottom of the reactor 1 is connected to a base 19, which supports the entire device and ensures the overall stability of the device when it is working.

[0030] The working principle of the utility model is as follows: when the device is in use, different kinds of materials are injected into the interior of the explosion-proof inner tank 2 through the material pipe 14, and the power mechanism is used to drive the rotating rod 4 and the stirring paddle 5 to rotate to stir the materials inside the device. When the reaction of various materials inside the device is completed, the reactants can be discharged through the discharge pipe 15, and the arc scraper 12 is driven to rotate by the rotating rod 4 to scrape off the water vapor attached to the top wall of the explosion-proof inner tank 2 during the hydrolysis process. When it is necessary to clean the top wall of the explosion-proof inner tank 2, the external water pipe is connected to the top of the rotating rod 4, so that the water body is input into the support tube 9 through the water injection groove 6 and the connecting groove 7, and then converged into the circular tube 10 through the support tube 9, and the top wall of the explosion-proof inner tank 2 can be sprayed by the nozzle 11 arranged on the circular tube 10, thereby completing the cleaning.

[0031] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model.
