DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the specific implementation manner of the utility model will be clearly and completely described below.

[0019] The present application discloses a uniformly mixed reactor 100, such as Figure 1As shown, the reactor 100 includes a reactor body 11, a driving motor 12, a heating device 13 and a control device 14. The reactor body 11 constitutes the basic frame of the reactor 100, and the driving motor 12, the heating device 13 and the control device 14 are arranged on the reactor 100. The bottom of the reactor body 11 is recessed inward to form a material collection cavity. The reactor body 11 includes a hollow cavity, a reactor body feed pipe 111 passing through the upper part, a reactor body discharge pipe 112 passing through the material collection cavity, and a plurality of support parts 113 arranged at the bottom of the reactor body 11. The support part 113 is used to support the reactor body 11. The reactor body feed pipe 111 is provided with a feed valve, and the reactor body discharge pipe 112 is provided with a discharge valve. The material collection chamber is formed by the bottom of the kettle body 11 being concave inward. When the reaction kettle 100 stirs the material, the material with a higher density will enter the material collection chamber under the action of gravity. The kettle body 11 is used to place the material so that the material can be stirred and reacted in the kettle body 11. The material is introduced into the kettle body 11 from the kettle body feed pipe 111, and after the kettle body 11 is stirred and reacted, it is discharged from the kettle body 11 from the kettle body discharge pipe 112. The drive motor 12 is arranged on the upper part of the kettle body 11, and the drive motor 12 includes a drive rod 121, which extends into the interior of the kettle body 11 close to the bottom of the kettle body 11, such as Figure 2As shown, the driving rod 121 includes a material guide spiral piece 122 arranged around the driving rod 121, and the end of the material guide spiral piece 122 away from the driving motor 12 is arranged in the material collection chamber, and a plurality of stirring blades 123 are arranged on the side of the material guide spiral piece 122 away from the driving rod 121. The driving motor 12 is used to drive the driving rod 121 to rotate, and the material guide spiral piece 122 and the stirring blade 123 on the driving rod 121 are used to stir the material in the kettle body 11. The material guide spiral piece 122 can also drive the lower part of the material kettle body 11 in the material collection chamber to move to the upper part of the kettle body 11 when the driving rod 121 drives the rotation, so that the material inside the kettle body 11 is tumbled up and down, so that the material is mixed evenly. The heating device 13 is arranged on one side of the outside of the kettle body 11, and the heating device 13 includes a plurality of heating parts 131, and the heating parts 131 are evenly distributed on one side of the middle part of the kettle body 11 and one side of the bottom of the kettle body 11. The heating parts 131 of the heating device 13 are evenly distributed on the kettle body 11. The uniform heating of the materials by the reactor 100 is achieved through the combined effect of the evenly distributed heating parts 131 and the material guide spiral blades 122 that tumble the materials in the kettle body 11 up and down. The control device 14 is arranged on one side outside the kettle body 11, and the control device 14 is electrically connected to the drive motor 12 and the heating device 13. The control device 14 is used to control the drive unit and the heating device 13, and set the appropriate power according to different reaction requirements and material characteristics. The reactor 100 of the present application collects the materials with higher density under the action of gravity in the material collection chamber through the material collection chamber, and then drives the materials in the material collection chamber from the bottom of the reactor 100 to the top of the reactor 100 through the material guide spiral blades 122 arranged in the material collection chamber at one end away from the drive motor 12, so that the materials inside the kettle body 11 are tumbled up and down, so that the materials are mixed evenly. There are gaps between the spiral blades of the material guide spiral blade 122. When the material is driven from the bottom of the reactor 100 to the top of the reactor 100, material will flow out from both sides of the gap. The power of the drive motor 12 can be adjusted by the control device 14 to control the rotation speed of the material guide spiral blade 122 and reduce the material flowing out from both sides of the gap.

[0020] As an embodiment, the end of the material guiding spiral blade 122 close to the bottom of the kettle body 11 includes a material guiding inlet 1221, and the end of the material guiding spiral blade 122 away from the bottom of the kettle body 11 includes a material guiding outlet 1222, and the material guiding inlet 1221 and the material guiding outlet 1222 are horizontally processed, such as Figure 3As shown, the material guiding spiral blade 122 is recessed downward from both sides toward the center to form a material guiding groove capable of guiding the material. The material guiding spiral blade 122 is used to guide the material in the reactor 100 to move from the lower part to the upper part of the reactor 100. The horizontal material guiding inlet 1221 and the material guiding outlet 1222 are provided to facilitate the material guiding spiral blade 122 to guide the material. The material guiding spiral blade 122 is provided to be recessed downward from both sides toward the center to form a material guiding groove capable of guiding the material, which further facilitates the material guiding spiral blade 122 to guide the material movement, so that the material moves up and down in the reactor 100 and is evenly mixed.

[0021] As an implementation mode, at least part of the plurality of stirring blades 123 is arranged below the material guide outlet 1222. The material guide spiral blade 122 is arranged on the driving rod 121 extending through the top of the reactor 100 and extending into the interior of the reactor body 11, so the position of the material guide outlet 1222 is close to the upper part of the reactor 100. When the material is put into the reactor 100, the material will not submerge the material guide outlet 1222 in many cases. Therefore, when the material guide spiral blade 122 is opened in the reactor 100, a lot of material will flow out from the material guide outlet 1222 of the material guide spiral blade 122. The present application arranges stirring blades 123 below the material guide outlet 1222, so that the material flowing out of the material guide outlet 1222 can be stirred and dispersed by the stirring blades 123, further improving the uniformity of the material stirring in the reactor 100.

[0022] As an implementation mode, the extension direction of the driving rod 121 is the extension direction of the driving rod 121, and the extension direction of the straight line tangent to the material guide spiral piece 122 is the extension direction of the tangent line of the material guide spiral piece 122. The angle α between the extension direction of the driving rod 121 and the extension direction of the tangent line of the material guide spiral piece 122 is greater than or equal to 60° and less than or equal to 90°. The main function of the material guide spiral piece 122 is to guide the material inside the kettle body 11 to move from bottom to top. Setting the spiral piece of the material guide spiral piece 122 with a suitable angle can more effectively guide the material forward, optimize the conveying effect of the material, ensure the smooth flow of the material, set a certain angle can improve the mixing and distribution uniformity of the material, and a reasonable angle helps to enhance the structural stability and bearing capacity of the spiral piece, better cope with the pressure and friction of the material, and ensure the normal operation and service life of the material guide spiral piece 122. Further, the angle α between the extension direction of the driving rod 121 and the extension direction of the tangent line of the material guide spiral piece 122 is greater than or equal to 75° and less than or equal to 85°. Furthermore, the angle α between the extension direction of the driving rod 121 and the extension direction of the tangent of the material guiding spiral piece 122 is 80°.

[0023] As an embodiment, the distance between the two sides of the material guiding spiral blade 122 is 80%-90% of the length of the stirring blade 123. In the reactor 100, the material guiding spiral blade 122 is used to guide and stir the material, and the stirring blade 123 is used to stir the material. When the reactor 100 is in use, it is necessary to consider the space occupied by the spiral blade in the reactor 100 to ensure the guiding effect on the material, and also to consider the space occupied by the stirring blade 123 in the reactor 100 to ensure the stirring effect on the material. In order to ensure the uniformity of the material in the reactor 100, the stirring effect needs to be guaranteed. Further, the distance between the two sides of the material guiding spiral blade 122 is 85% of the length of the stirring blade 123.

[0024] As an embodiment, the stirring blade 123 includes a plurality of blade through holes. The blade through holes allow the material to pass through the through holes better during the stirring process, increase the flow path and exchange of the material, make the stirring more uniform and sufficient, and reduce the overall stirring resistance to a certain extent when the material passes through the blade through holes, making the stirring operation smoother and reducing energy consumption. The blade through holes can also help different material components to mix and penetrate better, and promote more efficient chemical reactions or physical mixing processes. The blade through holes can also prevent certain materials from excessively accumulating on the blade surface, maintaining the continuity and stability of the stirring.

[0025] As an implementation manner, the shape of the stirring blade 123 is at least one of an arc, a rectangle, an ellipse, a fan, and a triangle.

[0026] As an embodiment, a pressure safety valve 15 for releasing pressure is provided on one side of the kettle body 11 near the top. When the pressure in the reactor 100 exceeds the set safety value, the pressure safety valve 15 automatically opens to release the excess pressure to prevent the reactor 100 from being damaged or even exploding due to excessive pressure.
