[0018] 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 in 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.

[0019] Figure 1It is a structural schematic diagram of the utility model. As shown in the figure, the reactor with temperature control function includes a reactor body 1, a feed hopper 11 is installed on one side of the top of the reactor body 1, and a discharge pipe 12 is connected to the bottom end of the reactor body 1. A valve is installed on the discharge pipe 12, and a guide tube 2 with upper and lower openings is installed inside the reactor body 1, and a drive motor 3 is installed at the top of the reactor body 1. The drive motor 3 is a stepping motor, and a connecting tube 4 is installed at the output end of the drive motor 3. A liftable stirring rod 5 is provided in the connecting tube 4, and the stirring rod 5 extends into the guide tube 2, and a stirring paddle 6 is installed at the lower end of the outer wall of the stirring rod 5.

[0020] Through the above technical solution:

[0021] During specific use, the raw materials to be reacted are added from the feed hopper 11 into the reactor body 1. During the reaction, the drive motor 3 can be started, and the drive motor 3 can be used to drive the stirring rod 5 equipped with the stirring paddle 6 to rotate slowly, so as to stir radially. During the radial stirring process, the stirring paddle 6 has a pulling effect on the liquid in the guide tube 2, so that the raw materials are suspended upward and overflow upward, thereby realizing axial flipping, improving the crystallization retention state, and then changing the flow field. The product after the reaction can be discharged and collected from the discharge pipe 12.

[0022] Further, see Figure 1 and Figure 2 As shown, an electric heating tube 8 is installed in the shell of the reactor body 1, temperature sensors 9 are installed on the inner walls of the reactor body 1 and the guide tube 2, and a controller 14 is installed on the outer wall of the reactor body 1.

[0023] As mentioned above, during the reaction, the controller 14 can be used to control the operation of the electric heating tube 8 to heat the inside of the reactor body 1, wherein the reactor body 1 can be used to monitor the internal temperature of the reactor body 1 in real time, and adjust the temperature change in time to play a role in temperature control.

[0024] Among them, see Figure 1 As shown, a bearing 13 is installed at the middle end of the outer wall of the stirring rod 5, and electric telescopic rods 7 are installed on the top of the inside of the reactor body 1 and on both sides of the stirring rod 5. The electric telescopic rod 7 and the outer ring of the bearing 13 are connected by a connecting strip.

[0025] Second, see Figure 3 As shown, a slide groove 15 is provided on the inner wall of the connecting tube 4 along the length direction, and a slide bar 16 is fixed to the upper end of the outer wall of the stirring rod 5 , and the slide bar 16 is slidably connected to the slide groove 15 .

[0026] Through the above, when the output end of the driving motor 3 drives the connecting tube 4 to rotate, the stirring rod 5 connected to the inner ring of the bearing 13 rotates accordingly, thereby achieving stirring;

[0027] Starting the electric telescopic rod 7 can drive the bearing 13 to move up and down, and then the stirring rod 5 can move up and down to realize axial auxiliary stirring, wherein the axial slide bar 16 is used to slide linearly in the slide groove 15, on the one hand, to ensure the stability of the up and down movement of the stirring rod 5, on the other hand, the stirring rod 5 can only move up and down along the connecting tube 4 and cannot rotate relative to it.

[0028] In addition, see Figure 1 As shown, a guide plate 10 is provided at the bottom of the reactor body 1 and at the bottom end of the guide tube 2. The upper end surface of the guide plate 10 is arched upward. The upwardly arched guide plate 10 is used for guiding flow, reducing the distance between the stirring paddle 6 and the bottom of the reactor, and can better stir and flip. If the guide plate 10 is not provided, large particles will settle and accumulate at the bottom of the reactor, making it impossible to flip upward.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
