[0021] Reference Figure 1-4 A reactor temperature control device comprises a reactor body 1, wherein two symmetrically arranged electric heating rods 8 are fixedly connected between the inner bottom and the inner top of the reactor body 1, and a cleaning mechanism for cleaning the electric heating rods 8 is arranged in the reactor body 1, and the cleaning mechanism comprises a moving plate 6 slidably connected in the reactor body 1, and two through grooves 15 are provided on the moving plate 6, and cleaning rings 16 are embedded in the two through grooves 15, and the inner wall of the cleaning ring 16 contacts the outer surface of the electric heating rod 8.

[0022] In the utility model, two electric heating rods 8 are respectively inserted into two cleaning rings 16 and cooperate with them. A moving mechanism for moving the moving plate 6 is provided in the reactor body 1. The moving mechanism includes two fixed blocks 13 respectively fixedly connected to the front and rear side walls of the moving plate 6. A reciprocating screw 12 is connected and rotated together between the inner bottom and the inner top of the reactor body 1. The reciprocating screw 12 passes through one of the fixed blocks 13 and cooperates with it. The rotation of the reciprocating screw 12 drives the moving plate 6 to move back and forth, so that the stirring mechanism moves back and forth. During the movement, the material in the reactor body 1 is stirred, which can greatly improve the stirring effect of the device.

[0023] In the utility model, a limiting mechanism for limiting the movable plate 6 is also provided in the reactor body 1, and the limiting mechanism includes a limiting rod 14 fixedly connected between the bottom and the top of the reactor body 1, and the limiting rod 14 passes through another fixed block 13 and is slidably connected thereto. The limiting rod 14 can limit the fixed block 13 and the movable plate 6, thereby improving the stability of the movable plate 6 during movement.

[0024] In the utility model, a stirring mechanism for stirring the material in the reactor body 1 is provided at the lower end of the movable plate 6, and the stirring mechanism includes a rotating ring 10 rotatably connected to the lower end of the movable plate 6, a threaded sleeve 11 is fixedly connected to the lower end of the rotating ring 10, and two symmetrically arranged stirring blades 7 are fixedly connected to the side wall of the threaded sleeve 11, a threaded rod 9 is fixedly connected between the inner bottom and the inner top of the reactor body 1, a through hole 17 is opened on the movable plate 6, the threaded rod 9 passes through the through hole 17 and is slidably connected thereto, and the threaded sleeve 11 is threadedly connected to the threaded rod 9.

The buffer pad can buffer the reactor body 1 and can also increase the friction with the ground, thereby improving the stability of the device.

[0026] When the utility model is used, the material is first injected into the reactor body 1 through the feed pipe 3, and then the material in the reactor body 1 is heated by the electric heating rod 8. During the heating process, the output shaft of the driving motor 5 rotates, driving the reciprocating screw 12 to rotate, thereby driving the movable plate 6 matched therewith to move back and forth in the reactor body 1. During the movement, the rotating ring 10, the threaded sleeve 11 and the stirring blade 7 are driven to move back and forth. Under the action of the threaded rod 9, the threaded sleeve 11 reciprocates, driving the stirring blade 7 to reciprocate, so as to achieve full stirring of the material in the reactor body 1 and improve the heating effect.
