[0004] In the prior art, in order to make the reaction more uniform and sufficient, the polymer needs to be stirred. For example, in a horizontal polymer reactor with a publication number of CN115475577A in the prior art, a stirring shaft is used to drive a stirring rod to rotate continuously for stirring. However, most polymers are relatively viscous, and continuous rotation and stirring can easily cause the polymer to splash and cause it to adhere to the inner wall of the reactor, which in turn prevents the polymer from fully flowing out during discharge and produces residue.

DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0023] In order to address the shortcomings of the existing technology, such as Figure 1-5 As shown, the utility model provides a horizontal polymer reactor, comprising a reaction container 1, a motor 7 is fixedly provided at one end of the reaction container 1, an output shaft of the motor 7 extends into the interior of the reaction container 1 and is fixedly provided with a drive shaft 12, a stirring shaft 9 is provided on an inner wall of one side of the reaction container 1 through a rotating shaft, and a toggle assembly 13 is provided at the outer ends of the stirring shaft 9 and the drive shaft 12;
[0024] The toggle assembly 13 includes a toggle plate 1301, and the two toggle plates 1301 are fixedly mounted on the outer ends of the driving shaft 12 and the stirring shaft 9, respectively. A mounting groove 1302 is formed at one end of the toggle plate 1301, and a roller 1303 is disposed on the inner wall of the mounting groove 1302 via a rotating shaft.
[0025] The polymer to be reacted is placed inside the reaction container 1, and the motor 7 is turned on. The driving shaft 12 is driven to rotate by the motor 7. During the rotation process, the driving shaft 12 drives the toggle component 13 fixed at the outer end thereof to rotate. When the toggle component 13 rotates to another toggle component 13 at the outer end of the stirring shaft 9, the two toggle plates 1301 are in contact with each other. During the contact process, the roller 1303 rolls to reduce the friction between the two toggle plates 1301. The toggle component 13 at the outer end of the driving shaft 12 toggles another toggle component 13 on the stirring shaft 9, thereby driving the stirring shaft 9 to rotate. As the toggle component 13 on the driving shaft 12 further rotates upward, the two toggle components 13 gradually separate, and this cycle is repeated. The driving shaft 12 toggles the stirring shaft 9 once every rotation, thereby driving the stirring shaft 9 to swing, and the polymer inside the reaction container 1 is stirred by the swing of the stirring shaft 9.
[0026] In order to perform reciprocating oscillating stirring, Figure 3 As shown, a plurality of stirring rods 10 are fixedly provided at the outer end of the stirring shaft 9, and the polymer is stirred by the swing of the stirring rods 10. A spring 11 is provided at the connection between the stirring shaft 9 and the inner wall of the reaction container 1, and the two ends of the spring 11 are fixedly connected to the outer end of the stirring shaft 9 and the inner wall of the reaction container 1 respectively.
[0027] When the driving shaft 12 rotates and moves the stirring shaft 9, the stirring shaft 9 and the stirring rod 10 at the outer end of the stirring shaft 9 are driven to rotate. During the rotation of the stirring shaft 9, the clockwork spring 11 is tightened. After the stirring shaft 9 and the stirring rod 10 rotate to a certain angle, the two moving components 13 are separated, and the elastic force of the clockwork spring 11 is released and drives the stirring shaft 9 and the stirring rod 10 to rotate back to their original positions, so that the stirring shaft 9 and the stirring rod 10 swing back and forth to stir the polymer. In this way, the stirring is performed in a swinging manner instead of the rotating manner in the prior art, which can prevent the polymer from splashing and adhering to the inner wall of the reaction vessel 1, thereby avoiding residue when discharging. In this stirring method, the polymer inside the reaction vessel 1 should not be too much, and the position of the polymer needs to be lower than that of the stirring shaft 9.
[0028] The polymer is automatically discharged after the reaction is completed, such as Figure 1 , 2 As shown, a feed pipe 8 is fixedly provided at the top of the reaction vessel 1, and the raw materials to be reacted are poured into the reaction vessel 1 through the feed pipe 8. An inspection end plate 2 is provided at the other end of the reaction vessel 1 through bolts, and the components inside the reaction vessel 1 can be inspected by disassembling the inspection end plate 2. A discharge pipe 3 is fixedly provided on one side of the inspection end plate 2, and valves are fixedly provided on the discharge pipe 3 and the feed pipe 8.
[0029] A plug plate 14 is fixedly provided at the bottom end of the reaction container 1, a support block 4 is provided at the bottom of the reaction container 1, a notch is opened at the top of the support block 4, the bottom end of the plug plate 14 extends into the notch and is movably connected to the inner wall of the notch through a rotating shaft, and the support block 4 can support the weight of the reaction container 1.
[0030] A support block 4 and an insert plate 14 are arranged at the bottom end of the reaction vessel 1, and the two can support the reaction vessel 1. When the reaction is completed and the material is discharged, the reaction vessel 1 can be controlled to rotate, and the insert plate 14 can be rotated relative to the support block 4. The reaction vessel 1 is tilted toward the end where the inspection end plate 2 is located. At this time, the valve on the discharge pipe 3 is opened, and the polymer will flow out through the discharge pipe 3 under the action of gravity, thereby realizing automatic discharge.
[0031] During discharge, the inclination of the reaction vessel 1 is automatically controlled by the lifting assembly 5. Figure 1 , 5 As shown, lifting components 5 are provided on both sides of the reaction container 1. The lifting components 5 include a hydraulic cylinder 501. A detachable mounting plate 502 is provided at the top of the piston rod of the hydraulic cylinder 501. The tilt angle of the reaction container 1 is adjusted by telescoping the hydraulic cylinder 501.
[0032] The mounting plate 502 is provided with a connecting shaft 503 penetrating the mounting plate 502 . The mounting plate 502 and the connecting shaft 503 are movably connected via a rotating shaft. When the hydraulic cylinder 501 is extended or retracted, the mounting plate 502 will rotate relative to the connecting shaft 503 .
[0033] Sliding plates 6 are provided on both sides of the reaction container 1 through slide rails. One end of the connecting shaft 503 is fixedly connected to the sliding plate 6 on the corresponding side. The sliding plate 6 can adjust its relative position with the reaction container 1 when the lifting assembly 5 is working.
[0034] When it is necessary to discharge the material, the piston rod of the lifting assembly 5 is controlled to move upward, thereby pushing one end of the reaction container 1 upward. During this process, the connecting shaft 503 rotates relative to the mounting plate 502, and the sliding plate 6 also moves slightly at the outer end of the reaction container 1. The upward movement of one end of the reaction container 1 realizes the tilting of the reaction container 1 to facilitate discharge of the material.
[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
