Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0026] Example: Figure 1 As shown, a defoamer preparation and feeding device includes a collection tank 1, a liquid outlet pipe 2, a spiral guide 3, a grinding device 4, and a feeding pipe 5. The collection tank 1 has a liquid inlet 101 and a powder inlet 102, and a liquid outlet pipe 2 is provided at its bottom.

[0027] The stirring mechanism 103 is installed inside the collection tank 1 and is used to stir and mix the materials in the collection tank 1. It consists of a stirring motor and a stirring shaft. The stirring shaft is installed inside the collection tank 1 and the stirring motor drives the stirring shaft to rotate.

[0028] A spiral guide element 3 is installed on the outlet pipe 2 to guide the mixture within the outlet pipe 2. For example... Figure 2 As shown, the spiral guide component 3 includes a connecting sleeve 301, a fixing bracket 302, and a guide vane 303. The connecting sleeve 301 connects between the front and rear liquid outlet pipes 2 via a threaded connection for easy disassembly and maintenance. Two fixing brackets 302 are fixed inside the connecting sleeve 301, connected to the front and rear ends of the guide vane 303. The guide vane 303 is disposed inside the connecting sleeve 301 and fixed to the fixing bracket 302.

[0029] The guide vanes 303 are spirally arranged along the axial direction and are evenly distributed around the circumference of the connecting sleeve 301, forming a spiral flow channel between adjacent guide vanes 303. The spiral guide can guide the flow of the mixture, keeping the mixture evenly distributed during the flow process and reducing material separation caused by inconsistent flow speeds.

[0030] The grinding device 4 is connected between the liquid outlet pipe 2 and the feed pipe 5 and is used to grind the particles in the mixture.

[0031] like Figure 3 As shown, the grinding device 4 includes a grinding shell 401, a fixed mill 402, a moving mill 403, and a motor 404. The moving mill 403 is rotatably mounted inside the grinding shell 401. The fixed mill 402 is fixed inside the grinding shell 401 and located outside the moving mill 403. The front end of the grinding shell 401 is connected to the liquid outlet pipe 2, and its rear end is connected to the feed pipe 5. The rear end of the moving mill 403 is connected to the motor 404. Toothed protrusions are distributed on the adjacent sidewalls of the fixed mill 402 and the moving mill 403.

[0032] The inlet of the grinding housing 401 faces the front end face of the stationary mill 402. Multiple guide grooves 405 are circumferentially distributed on the front end face of the stationary mill 402, extending radially from the center of the stationary mill 402 to the sidewall. When the mixture enters the grinding housing 401 through the inlet, it first enters the guide grooves 405 on the front end face of the stationary mill 402, then, under centrifugal force, enters the gap between the stationary mill 402 and the moving mill 403, and finally enters the feed pipe 5.

[0033] The center of the fixed mill 402 is provided with a drain hole 406, which extends from the front end of the fixed mill 402 to the rear end. A filter screen 408 is provided at the front end of the drain hole 406, and a connecting end 6 is provided at the rear end of the fixed mill 402. The connecting end 6 is connected to the feed pipe 5 through the drain pipe 7.

[0034] The stationary mill 402 is rotatably connected to the connecting end 6. The stationary mill 402 is provided with a through hole 407 that connects to the drain hole 406. The inner wall of the connecting end 6 is provided with an annular connecting groove 601, and the through hole 407 is located in the annular connecting groove 601. The diameter of the liquid inlet of the grinding shell 401 is larger than the diameter of the drain hole 406. During operation, because the flow rate of the mixed liquid entering the grinding shell 401 is greater than the flow rate discharged through the drain hole 406, some of the mixed liquid will enter the gap between the stationary mill 402 and the moving mill 403. Large particles are blocked by the filter screen 408 and enter the gap between the stationary mill 402 and the moving mill 403 with the flow rate through the guide groove 405, while small particles pass directly through the filter screen and enter the feed pipe 5 through the drain pipe 7. This increases the grinding efficiency of the grinding device 4.
