DETAILED DESCRIPTION

[0023] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0024] Depend on Figure 1 Combination Figure 2-3 As shown, a reactor with a cooling function comprises a tank body 1, wherein a stirring space 11 is provided in the tank body 1, and further comprises:

[0025] The stirring shaft 2 is arranged on the tank body 1 and inserted into the stirring space 11, and is rotatably arranged relative to the tank body 1;

[0026] A stirring blade 3 is arranged on the stirring shaft 2 and is linked to the stirring shaft 2;

[0027] The cooling baffle 4 is arranged on the inner wall of the tank body 1 and is arranged toward the center of the stirring space 11. The cooling baffle 4 is provided with a cooling cavity 41 for the circulation of the cooling medium. The beneficial effect of the utility model is that a cooling baffle is provided to increase the stirring effect. At the same time, a cooling cavity is provided on the cooling baffle, and the medium in the stirring tank can be cooled by the medium in the cooling cavity, that is, the cooling baffle also plays a heat exchange effect, which reduces the setting of the cooling coil in the tank, reduces the difficulty of assembly, and is easy to install and maintain. The utility model also has the advantages of simple structure, easy assembly, good cooling effect, and long service life. The utility model makes the cooling baffle into a hollow structure that can pass the cooling medium (usually the cooling medium is water). While enhancing the stirring effect, the cooling water can also be used to exchange heat with the material inside the reactor, which greatly reduces the number of internal parts of the reactor and optimizes the stirring interference factors of the reactor.

[0028] There are multiple cooling baffles 4, and the multiple cooling baffles 4 are evenly distributed on the inner wall of the tank body 1 in the circumferential direction. Such a structure is easy to install and has a simple structure. The utility model also includes a support assembly 5, which is arranged on the inner wall of the tank body 1 and is used to support the cooling baffle 4. More specifically, each cooling baffle 4 is supported and limited by multiple support assemblies 5, and different support assemblies 5 are equidistantly arranged along the vertical direction of the cooling baffle 4. Such a structure makes the product strong and the cooling baffle is not easy to deform. The cooling baffle is arranged at the position where the stirring fluid has turbulence, and the surface is not easy to adhere to materials, and the heat exchange effect is good.

[0029] The support assembly 5 includes a first support plate 51 and a second support plate 52, both of which are arranged on the inner wall of the tank body 1, and the cooling baffle 4 is arranged between the first support plate 51 and the second support plate 52. Specifically, the first support plate 51 is provided with a first inclined surface 511, and the second support plate 52 is provided with a second inclined surface 521, and the inclined direction of the first inclined surface 511 and the inclined direction of the second inclined surface 521 are symmetrically arranged with respect to the cooling baffle 4. Specifically, the first support plate 51 is arranged on the impact surface of the stirring medium when the stirring shaft 2 is working, and the distance that the first support plate 51 extends into the center of the tank body is less than the distance that the second support plate 52 extends into the center of the tank body 1. The second inclined surface can play a supporting role to prevent the cooling baffle from being deformed. Such a structure allows the cooling baffle to be arranged at a position where the stirring fluid is turbulent, and the surface is not easy to adhere to materials, and the heat exchange effect is good.

[0030] A mounting groove is provided between the first support plate 51 and the second support plate 52, and the cooling baffle 4 is inserted into the mounting groove, and a flow cavity 53 is formed between the cooling baffle 4 and the inner wall of the tank body 1. The setting of the flow cavity facilitates the flow of the medium, avoids the formation of dead corners, avoids the accumulation of the medium, and facilitates cleaning.

[0031] The cooling baffle 4 is provided with a flow hole 42, and the flow hole 42 is connected with the cooling cavity 41. Specifically, a cooling pipe 6 is provided on the outer surface of the tank body 1. Such a structure makes the product structure simple and has a good heat dissipation effect.
