Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example:

A stirring shaft 3 is fixedly installed at the output end of the motor 2. A stirring plate 4 is fixedly sleeved on the outer wall of the stirring shaft 3. Two inclined plates 5 are fixedly installed on the outer wall of the stirring plate 4. A bottom plate 6 is slidably connected to the inside of the reaction tank 1. Two top rods 7 are fixedly welded to the bottom of the bottom plate 6. Two springs 8 are fixedly welded to the outer wall of the bottom plate 6. Two stabilizing plates 9 are fixedly installed on the inner side of the reaction tank 1. A rotating plate 10 is fixedly sleeved on the outer wall of the stirring shaft 3.

After the motor 2 is turned on, it drives the stirring shaft 3 to rotate. The stirring shaft 3 will drive the stirring plate 4 and the inclined plate 5 to rotate, which will drive the material inside the reaction tank 1 to stir. The inclined plate 5 can achieve the effect of tumbling the material, which can achieve a better stirring effect. When stirring, the stirring shaft 3 can drive the rotating plate 10 to rotate. The rotating plate 10 will drive the arc plate 11 to rotate. The arc plate 11 will squeeze the top rod 7. The top rod 7 will drive the bottom plate 6 to move upward. When the arc plate 11 moves away, under the action of the spring 8, the bottom plate 6 will be stretched to move downward, which can drive the material to move up and down. It can change the stirring position between the stirring plate 4 and the inclined plate 5 to achieve a better stirring effect. This solves the problems of existing bioreactors for soil remediation, which are complex in structure, high in manufacturing cost, cumbersome in use, and have poor stirring effect, resulting in incomplete biological reaction and low efficiency in soil remediation.

[0027] Specifically, the push rod 7 is slidably connected to the stabilizing plate 9, which can achieve the effect of stabilizing the movement of the push rod 7. The spring 8 is fixedly connected to the stabilizing plate 9, which can achieve the effect of supporting the spring 8 and applying a supporting force to the spring 8.

The bottom end of the push rod 7 is arc-shaped, which makes it easier to push the bottom plate 6 to move upward.
[0030] In the embodiment: two inclined plates 5 are arranged in a circular array on the outside of the stirring shaft 3, and an observation window is provided on the outer wall of the reaction tank 1, and the inside of the observation window is provided with glass.
[0031] Specifically, the inclined plates 5 are arranged in a circular array on the outside of the stirring shaft 3, which can achieve better stirring effect. The outer wall of the reaction tank 1 is provided with an observation window, and the inside of the observation window is equipped with glass, which can facilitate the observation of the stirring effect inside the reaction tank 1.

It is common knowledge in the art, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.
[0033] Working principle: The materials and reactants are placed into the feed pipe 14. The motor 2 is turned on to drive the stirring shaft 3 to rotate, which in turn drives the stirring plate 4 and the inclined plate 5 to rotate, thus stirring the materials inside the reaction tank 1. When stirring, the stirring shaft 3 drives the rotating plate 10 to rotate, which in turn drives the arc plate 11 to rotate. The arc plate 11 will squeeze the top rod 7, causing the bottom plate 6 to move upward. When the arc plate 11 moves away, the materials can move up and down under the action of the spring 8, which can change the stirring position between the stirring plate 4 and the inclined plate 5.
