[0022] By setting the filter 14, when defoaming, it is only necessary to use the sliding filter 14 to filter out the foam on the liquid surface, and then use the fan 8 to blow the foam into the storage box 3. The whole process is fast and convenient, and the stirring state of the stirring device is not changed.

[0023] like Figure 5As shown, the lifting structure includes a lifting block 23 and a sliding cylinder 24. The lifting block 23 is slidably arranged in the adjusting cylinder 4, and the sliding cylinder 24 is fixedly connected to the bottom of the lifting block 23; a connecting rod 16 is fixedly connected to the bottom of the sliding cylinder 24, and the connecting rod 16 is fixedly connected to the filter 14.

[0026] Principle of the utility model

[0027] like Figure 1-2 As shown, when the stirring device is working normally, the raw materials required for producing liquid fertilizer are added from the water inlet 6, and the liquid fertilizer is stirred by the stirring motor 11 and the stirring shaft 12. After the mixing production is completed, it can be discharged from the water outlet pipe 10. Figure 3-4 As shown, the filter screen 14 is placed below the liquid surface. When more foam is generated on the liquid surface, the micromotor 21 is started. Driven by the lifting structure, the filter screen 14 moves upward. When the filter screen 14 comes out of the liquid surface, a large amount of foam can be filtered out, and the foam is driven to the position corresponding to the fan 8. The fan 8 is started to blow the foam on the filter screen 14 into the storage box 3 through the slot 15, so that the defoaming work can be completed quickly. The whole process will not change the normal stirring parameters, and there is no need to add chemical substances such as defoaming agents to the liquid fertilizer to affect the composition of the liquid fertilizer.

[0028] like Figure 3-4 As shown, when the liquid level in the mixing box 2 changes during the mixing process, since the chute 17 is connected to the mixing box 2 through the connecting hole 20, the liquid level in the chute 17 will also change, thereby driving the floating block 18 and the displacement sensor 19 to move. The displacement sensor 19 transmits the displacement data to the controller 9, and the controller 9 controls the micromotor 21, thereby using the lifting structure to adjust the height of the filter screen 14, thereby ensuring that the filter screen 14 is always below the liquid level, which is convenient for filtering the foam on the liquid surface.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
