[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The following is combined with Figure 1-7 The present invention is further described.

[0030] In order to solve the problems existing in the background technology, the present application proposes the following technical scheme: a chemical reactor comprises a reactor body 1, a reactor cover 2 is detachably mounted on the reactor body 1, a feed pipe 3 is fixedly mounted on the reactor cover 2, a pipe cover 4 is detachably connected to the feed pipe 3, a pressure gauge 7 is fixedly mounted on the reactor cover 2, a discharge pipe 5 is fixedly connected to the bottom of the reactor body 1, an electromagnetic valve 6 is fixedly mounted on the discharge pipe 5, a mounting frame 8 is fixedly connected to the reactor cover 2, a drive motor 9 is fixedly mounted on the mounting frame 8, a rotating shaft 10 is coaxially fixedly connected to the drive shaft of the drive motor 9, the rotating shaft 10 is rotatably mounted in the reactor body 1, a mounting plate 11 is fixedly mounted on the outside of the rotating shaft 10, a plurality of groups of connecting blocks 12 are fixedly connected to the mounting plate 11, arc plates 13 are fixedly mounted on both upper and lower ends of the connecting block 12, and an auxiliary stirring mechanism is also provided in the reactor body 1.

[0031] The reactor body 1 and the reactor cover 2 are detachably connected, which is convenient for cleaning and maintaining the inner walls of the reactor body 1 and the reactor cover 2. The inner walls of the reactor body 1 and the reactor cover 2 are finely ground and polished to improve the smoothness of the inner walls and reduce the phenomenon of material adhesion on the inner walls. The feed pipe 3 adopts a side pipe design to allow the material to slowly fall into the reactor body 1 at a certain angle to avoid splashing the material onto the inner wall of the reactor body 1. The pressure gauge 7 can monitor the changes in the internal pressure of the reactor body 1, and can timely understand the progress of the chemical reaction, so as to take corresponding measures. The material is slowly added to the reactor body 1 through the feed pipe 3, and then the pipe cover 4 is installed on the feed pipe 3 to ensure that the reactor body 1 is closed. The drive motor 9 drives the shaft 10 to rotate, and the shaft 10 drives the mounting plate 11 to rotate. The mounting plate 11 drives the arc plate 13 to rotate through the connecting block 12. The rotation direction of the arc plate 13 is the same as its inner arc surface. The arc plate 13 rotates to throw the material around, forming a strong radial flow. This flow mode helps to flush the material on the reactor wall, thereby reducing the occurrence of wall hanging. During the chemical reaction process, if the material adheres to the reactor wall for a long time, it may cause problems such as uneven reaction, poor heat transfer and material waste. The use of a radial flow agitator can effectively solve these problems, improve reaction efficiency and product quality. At the same time, the arc plate 13 can generate a large shear force during the stirring process, so that the material particles are dispersed more finely. This shear force helps to promote the chemical reaction, improve the reaction rate and product quality. The auxiliary stirring mechanism is used to further improve the stirring effect of the material. After sufficient reaction, the material is discharged from the reactor body 1 through the discharge pipe 5, and the electromagnetic valve 6 controls the switch of the discharge pipe 5.

[0032] It is further explained that a propeller agitator 14 is fixedly mounted on the outside of the rotating shaft 10 , and the propeller agitator 14 is arranged below the mounting plate 11 .

[0033] The rotating shaft 10 can also drive the propeller agitator 14 to rotate. The propeller agitator 14 generates a driving force to lift the material at the bottom of the reactor body 1 upward. The lifted material passes through the rotating arc plate 13 to form a radial flow. The propeller agitator 14 cooperates with the arc plate 13 to achieve a better stirring effect on the material.

[0034] It is further explained that the auxiliary stirring mechanism includes a mounting plate 15 and a stirring plate 16 fixedly mounted on the outside of the rotating shaft 10, a rotating rod 17 rotatably mounted between the mounting plate 15 and the stirring plate 16, a stirring block 18 fixedly mounted on the outside of the rotating rod 17 and a gear 22 fixedly mounted on one end of the rotating rod 17, and a gear ring 21 is arranged inside the reactor body 1, and the gear ring 21 is meshed with the gear 22.

[0035] The rotating shaft 10 can also drive the mounting plate 15 and the stirring plate 16 to rotate at the same time. The mounting plate 15 and the stirring plate 16 drive the rotating rod 17 to rotate. The rotating rod 17 rotates around the rotating shaft 10. The rotating rod 17 drives the stirring block 18 to rotate to stir the material. While the rotating rod 17 rotates around the rotating shaft 10, the gear 22 is meshed with the gear ring 21. The gear 22 drives the rotating rod 17 to rotate, so that the rotating rod 17 rotates on itself, so that the stirring block 18 rotates around the rotating rod 17. The stirring block 18 forms an axial flow for the material. The stirring block 18 stirs the material around the inside of the reactor body 1, and cooperates with the arc plate 13 and the propulsion agitator 14 to stir the material in the middle of the reactor body 1, thereby stirring the material. The materials inside the reactor body 1 are fully stirred to improve the chemical reaction rate and product quality. In the actual use of the reactor body 1, the reactants shall generally not be less than 30% and not more than 80%. However, in the case of high-viscosity reactants that are easy to adhere to the inner wall of the reactor body 1, the reactants shall not be greater than 2 / 3 of the volume of the reactor body 1, so that the reactants are not easy to adhere to the gear 22 and the gear ring 21. At the same time, the reactor body 1 and the reactor cover 2 are detachably connected. After long-term use, the reactor cover 2 can be removed to clean the parts inside the reactor body 1 such as the gear 22 and the stirring block 18, thereby improving the service life and normal use of the reactor body 1.

[0036] It is further explained that an annular splash plate 20 is fixedly mounted on the inner wall of the reactor body 1 , and the gear ring 21 is fixedly mounted on the inner circumferential surface of the annular splash plate 20 .

[0037] The annular splash plate 20 provides installation conditions for the gear ring 21. At the same time, when the stirring block 18 stirs the material, the annular splash plate 20 can effectively prevent the axial flow material from splashing onto the inner wall of the kettle cover 2, avoid the material from adhering to the inner wall of the kettle cover 2, and reduce the cost of cleaning and maintenance of the kettle cover 2.

[0038] It is further explained that a scraper plate 23 is fixedly mounted on the mounting plate 15 , and the upper end of the scraper plate 23 is in contact with the lower end surface of the annular splash plate 20 .

[0039] The material in the axial flow will splash and adhere to the lower end surface of the annular splash plate 20. During the stirring process, the mounting plate 15 will drive the scraper 23 to rotate, and the scraper 23 will scrape the material adhered to the lower end surface of the annular splash plate 20. The scraped material will fall back into the reactor body 1, avoiding waste of material and reducing the cleaning cost of the annular splash plate 20.

[0040] It is further explained that a movable cavity 25 is provided on the stirring block 18 , a stirring paddle 19 is slidably installed in the movable cavity 25 , a spring 28 is fixedly installed at the bottom of the movable cavity 25 , and one end of the spring 28 is fixedly connected to one side of the stirring paddle 19 .

[0041] When the rotating rod 17 drives the stirring block 18 to rotate, centrifugal force is generated when the stirring block 18 rotates, causing the stirring paddle 19 to slide out of the active cavity 25. One end of the stirring paddle 19 contacts the inside of the reactor body 1. As the stirring block 18 drives the stirring paddle 19 to rotate, one end of the stirring paddle 19 scrapes off the material adhering to the inside of the reactor body 1, which can effectively prevent the material from adhering to the inner wall of the reactor body 1. The spring 28 acts as a buffer for the stirring paddle 19, preventing the stirring paddle 19 from rapidly sliding out of the active cavity 25 and hitting the inner wall of the reactor body 1 under the action of centrifugal force, thereby improving the practicality of the stirring paddle 19.

[0042] It is further explained that a limiting groove 26 is provided on the side wall of the movable cavity 25 , a limiting block 27 is slidably installed in the limiting groove 26 , and the limiting block 27 is fixedly connected to the stirring paddle 19 .

[0043] The limiting block 27 cooperates with the limiting groove 26 to guide and limit the movement of the stirring paddle 19, thereby improving the smoothness of the sliding of the stirring paddle 19 in the active cavity 25 and improving the stability of the auxiliary stirring mechanism.

[0044] It is further explained that the bottom of the active chamber 25 and one side of the stirring paddle 19 are both fixedly connected with a guide column 29 , and the spring 28 is sleeved on the outside of the guide column 29 .

[0045] The guide column 29 guides and limits the spring 28 , thereby preventing the spring 28 from deflecting during deformation and improving the stability of the spring 28 during use.

[0046] Furthermore, a curved surface 24 is formed on one side of the stirring plate 16 , and the direction of the curved surface 24 is the same as the inner curved surface of the curved plate 13 .

[0047] When the rotating shaft 10 rotates, the stirring plate 16 is driven to rotate at the same time. The direction of the arc surface 24 is the same as the rotation direction. The rotating stirring plate 16 stirs the material deposited at the bottom of the reactor body 1, causing it to move along the arc surface 24. The stirred material is lifted upward by the propeller agitator 14, so that the material inside the reactor body 1 is fully stirred, and the stirring dead angle is eliminated as much as possible, thereby improving the reaction efficiency and product quality.

[0048] It is further explained that a heating resistor 30 is fixedly installed in the reactor body 1 , a controller 31 is fixedly installed outside the reactor body 1 , the controller 31 is electrically connected to the heating resistor 30 , and a heat preservation sleeve 32 is provided outside the reactor body 1 .

[0049] The heating resistance wire 30 is set in a spiral shape. The heating resistance wire 30 can increase the temperature of the material during the reaction of the reactor body 1. The temperature of the material during the reaction can be controlled by the controller 31 in cooperation with the heating resistance wire 30 to avoid crystallization of the material when the reaction temperature is too low and reduce the adhesion of the material to the inner wall of the reactor body 1. The setting of the insulation sleeve 32 can effectively reduce the heat loss of the reactor body 1, which is beneficial to saving energy. The controller 31 adopts a PLC programmable controller.

[0050] Specific reference is made to the following operation: the material is slowly added into the reactor body 1 through the feed pipe 3, and then the pipe cover 4 is installed on the feed pipe 3, the driving motor 9 drives the rotating shaft 10 to rotate, the rotating shaft 10 drives the mounting plate 11 to rotate, and the mounting plate 11 drives the arc plate 13 to rotate through the connecting block 12, and the arc plate 13 rotates to throw the material to the surroundings, forming a strong radial flow, and the rotating shaft 10 can also drive the propulsion agitator 14 to rotate, and the propulsion agitator 14 generates a driving force to lift the material at the bottom of the reactor body 1 upward, and the lifted material passes through the rotating arc plate 13 to form a radial flow, and the rotating shaft 10 can also drive the mounting plate 15 and the stirring plate 16 to rotate at the same time, and the mounting plate 15 and the stirring plate 16 drive the rotating rod 17 to rotate, and the rotating rod 17 rotates around the rotating shaft 10, and the rotating rod 17 drives the stirring block 18 to rotate to stir the material, and while the rotating rod 17 rotates around the rotating shaft 10, the gear 22 is meshed with the gear ring 21, and the gear 22 drives the rotating rod 17 to rotate, so that the rotating rod 17 rotates on itself, so that the stirring The block 18 rotates around the rotating rod 17, and the stirring block 18 makes the material form an axial flow. The stirring block 18 stirs the materials around the inside of the reactor body 1, and cooperates with the arc plate 13 and the propulsion agitator 14 to stir the materials in the middle of the reactor body 1, so as to fully stir the materials inside the reactor body 1. The mounting plate 15 will drive the scraper 23 to rotate, and the scraper 23 scrapes the materials adhered to the lower end surface of the annular splash plate 20. In the process of the stirring block 18 driven by the rotating rod 17 to rotate, the stirring block 18 will generate centrifugal force when rotating, so that the stirring paddle 19 slides out of the active cavity 25, and one end of the stirring paddle 19 contacts the inside of the reactor body 1. As the stirring block 18 drives the stirring paddle 19 to rotate, one end of the stirring paddle 19 scrapes the materials adhered to the inside of the reactor body 1, which can effectively prevent the materials from adhering to the inner wall of the reactor body 1, reduce the cleaning and maintenance costs of the reactor body 1, and the fully reacted materials are discharged from the reactor body 1 through the discharge pipe 5.
