[0019] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] See also Figure 1 and Figure 2 The utility model provides a stirring structure for a reactor, which comprises a reactor body 1 and a stirring structure installed on the reactor body 1; the reactor body 1 comprises a tank body 11 and a snap-fit ​​cover 12 covering the upper end thereof, and adding or discharging the solvent in the tank body can be performed by opening the snap-fit ​​cover 12, or a special supply port 13 and a discharge port can be set on the outer wall of the reactor body 1.

[0021] The stirring structure includes a stirring shaft 2 extending into the interior of the reactor body 1, a driver 3 driving the stirring shaft 2 to rotate, and a plurality of stirring paddles 4 installed at the end of the stirring shaft 2. In the present embodiment, the stirring paddles 4 are provided in two groups, and are arranged relative to each other (of course, the number and distribution of the stirring paddles 4 can be adaptively set as needed, for example, three groups, four groups, etc.), and the shape of the stirring paddles 4 is adaptively set as needed; specifically in the present embodiment, in order to optimize the mixing effect of the liquid, the stirring shaft 2 is aligned with the axis of the tank body 11, the driver 3 can be a traditional motor and is installed on the snap-on cover 12, and the end of the stirring shaft 2 is fixedly connected to the driving shaft of the motor.

[0022] When stirring is performed, the driver 3 is started to drive the stirring shaft 2 to rotate, and further drives the stirring paddle 4 to rotate, so as to achieve stirring of the solvent.

[0023] See also Figure 2 and Figure 3 Each stirring paddle 4 is hinged to the end of the stirring shaft 2. Specifically, the end of the stirring shaft 2 is provided with a hinge buckle for connection. The stirring paddle 4 is installed in the hinge buckle through the hinge shaft. The stirring paddle 4 rotating around the hinge can switch between a working state and a non-working state. The stirring paddle 4 in the working state forms a predetermined angle with the stirring shaft 2. Specifically, in this embodiment, the stirring paddle 4 is vertically arranged with the stirring shaft 2. The stirring effect is best at this angle.

[0024] The end of the stirring paddle 4 in the non-working state rests on the stirring shaft 2 or is close to the stirring paddle 4. The above-mentioned non-working state is applied during the assembly of the equipment. In this state, the stirring paddle 4 occupies a small space (the diameter of the occupied space is small), and can easily pass through the mouth of the tank body 11 (provided that the diameter of the space occupied by the stirring paddle 4 in the non-working state is smaller than the diameter of the mouth of the tank body 11).

[0025] It should be further explained that the switching between the working state and the non-working state of the stirring paddle 4 is achieved by the following structure: a return spring (torsion spring) is installed at the hinge between the stirring shaft 2 and the stirring paddle 4 to drive the stirring paddle 4 to enter the working state. A blocking portion 5 is provided at the hinge between the stirring shaft 2 and the stirring paddle 4 to limit the working angle of the stirring paddle 4, and the blocking portion 5 can be a positioning block.

[0026] See also Figure 4 At the same time, the above state is also applied when the equipment is in the process of transportation. Further, on the basis of the above state, a positioning assembly is used to fix the plurality of stirring paddles 4. Specifically, the positioning assembly includes a connection portion 41 provided at each stirring paddle 4 away from the hinged end, and the connection portions 41 of the stirring paddles 4 at adjacent positions are detachably connected. Further, the connection portions 41 of the stirring paddles 4 at adjacent positions are fixedly connected by threaded connectors. The positioning assembly allows the stirring paddle 4 to remain stable in the non-working state, further ensuring the stability of the equipment state during transportation.

[0027] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
