The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figures 1-6The utility model provides a technical solution: a pesticide preparation compound purification device, comprising an extraction tank 1 and a liquid separation tank 2, wherein one end of the top of the extraction tank 1 is provided with a feeding port 3, one end of the bottom of the side wall of the extraction tank 1 is connected to a first water pump 4, the output end of the first water pump 4 is connected to a first connecting pipe 5, the top of the first connecting pipe 5 is connected to a filter tank 6, a filter screen 7 is provided inside the filter tank 6, the bottom of the filter tank 6 is connected to the extraction tank 1 through a second connecting pipe 8, an adjacent end of the extraction tank 1 is provided with a liquid separation tank 2, the extraction tank 1 is connected to the liquid separation tank 2, the liquid separation tank 2 is funnel-shaped, and a sleeve is provided at the bottom of the liquid separation tank 2. 9, one end of the sleeve 9 is connected to a first discharge pipe 10, and the other end of the sleeve 9 is connected to a second discharge pipe 11; the bottom of the liquid separator 2 is connected to a cylindrical tube 12, and the bottom of the cylindrical tube 12 is connected to the bottom of the sleeve 9, and the side wall of the sleeve 9 is provided with through holes 13 at the cylindrical tube 12, the first discharge pipe 10 and the second discharge pipe 11; a plug 14 is rotatably connected to the sleeve 9, and a first flow channel 15 is provided at one end of the plug 14, and a second flow channel 16 is provided at the end of the plug 14 away from the first flow channel 15, and the first flow channel 15 and the second flow channel 16 are symmetrically distributed, and a knob 17 is fixedly connected to one end of the plug 14;

[0024] In this embodiment, when purifying the pesticide, the pesticide is first injected into the extraction tank 1 through the feed port 3, and then the extractant for purifying the pesticide is placed in the extraction tank 1. The extractant can interact with the extracted substance (such as the active ingredient or impurities in the pesticide) due to its specific chemical structure and properties to form an extractant soluble in the organic phase, thereby achieving separation and purification of the substance. After the extractant is placed in the extraction tank 1, the first water pump 4 is turned on, and the pesticide in the extraction tank 1 is transported to the filter tank 6 through the first water pump 4, so that the filter screen 7 in the filter tank 6 can filter out the solid impurities in the pesticide. In addition, the action of the first water pump 4 can transport the pesticide at the bottom of the extraction tank 1 to the top of the extraction tank 1, so that the pesticide can flow up and down in the extraction tank 1, thereby increasing the fluidity of the pesticide, and then To speed up the mixing of the extractant and the pesticide, when the pesticide and the extractant are fully mixed, they need to be transported to the separator tank 2 for standing and separation. After a period of standing, the drug components and impurity liquids in the pesticide will be stratified. At this time, the knob 17 can be turned to drive the stopcock 14 to rotate, so that one end of the first flow channel 15 in the stopcock 14 is connected to the through hole 13 at the bottom of the columnar tube 12. At this time, the liquid in the lower layer of the separator tank 2 will be discharged through the first discharge pipe 10. After the liquid in the lower layer of the separator tank 2 is discharged, the stopcock 14 is rotated again to allow one end of the second flow channel 16 in the stopcock 14 to be connected to the through hole 13 at the bottom of the columnar tube 12. At this time, the remaining liquid in the separator tank 2 will be discharged from the second discharge pipe 11, so that the purified pesticide and liquid impurities can be discharged separately, which is convenient for collection by the staff.

[0025] like Figure 6 As shown, a motor 18 is fixedly connected to the top of the extraction tank 1, an output end of the motor 18 is fixedly connected to a stirring shaft 19, and three stirring blades 20 are fixedly connected to both ends of the stirring shaft 19;

[0026] In this embodiment, when the pesticide is extracted, the motor 18 is turned on, and the stirring shaft 19 is driven by the motor 18 to rotate, thereby driving the stirring blade 20 to rotate, thereby stirring the pesticide so that the pesticide can be fully mixed with the extractant.

[0027] like Figure 1 and Figure 6 As shown, the bottom center of the extraction tank 1 is connected to a third connecting pipe 21, one end of the third connecting pipe 21 is connected to the liquid separator 2, and a valve 22 is installed at one end of the third connecting pipe 21 located at the extraction tank 1;

[0028] In this embodiment, the design of the third connecting pipe 21 allows the extraction tank 1 to be smoothly connected to the separator tank 2, and the design of the valve 22 can control the discharge of the pesticide in the extraction tank 1, so that the pesticide can be fully stirred in the extraction tank 1 before being discharged from the extraction tank 1.

[0029] like Figure 1 As shown, one end of the third connecting pipe 21 is connected to the second water pump 23, the output end of the second water pump 23 is connected to the fourth connecting pipe 24, and one end of the fourth connecting pipe 24 is connected to the liquid separation tank 2;

[0030] In this embodiment, after the pesticide is fully stirred in the extraction tank 1, the valve 22 is opened first, and then the second water pump 23 is turned on. Under the action of the second water pump 23, the pesticide will flow into the separation tank 2 through the third connecting pipe 21 and the fourth connecting pipe 24 to facilitate static separation.

[0031] Working principle: When purifying pesticides, first inject the pesticide into the extraction tank 1 through the feeding port 3, and then put the extractant for pesticide purification into the extraction tank 1. After the extractant is put into the extraction tank 1, turn on the motor 18. Driven by the motor 18, the stirring shaft 19 will rotate, thereby driving the stirring blade 20 to rotate, so as to stir the pesticide, so that the pesticide can be fully mixed with the extractant. While stirring, the first water pump 4 can be turned on to transport the pesticide in the extraction tank 1 to the filter tank 6 through the first water pump 4, so that the filter screen 7 in the filter tank 6 can filter out the solid impurities in the pesticide. Moreover, the action of the first water pump 4 can transport the pesticide at the bottom of the extraction tank 1 to the top of the extraction tank 1, so that the pesticide can flow up and down in the extraction tank 1, and at the same time cooperate with the stirring of the stirring shaft 19 and the stirring blade 20 to accelerate the mixing of the extractant and the pesticide. When the pesticide and the extractant are fully mixed , first open the valve 22, then turn on the second water pump 23. Under the action of the second water pump 23, the pesticide will flow into the separating tank 2 through the third connecting pipe 21 and the fourth connecting pipe 24. The pesticide will stand in the separating tank 2 for a period of time, so that the drug components and impurity liquids in the pesticide will be separated. At this time, the knob 17 can be turned to drive the stopcock 14 to rotate, so that one end of the first flow channel 15 in the stopcock 14 is connected to the through hole 13 at the bottom of the cylindrical tube 12. At this time, the liquid in the lower layer of the separating tank 2 will be discharged through the first discharge pipe 10. After the liquid in the lower layer of the separating tank 2 is discharged, the stopcock 14 is rotated again to allow one end of the second flow channel 16 in the stopcock 14 to be connected to the through hole 13 at the bottom of the cylindrical tube 12. At this time, the remaining liquid in the separating tank 2 will be discharged from the second discharge pipe 11, so that the purified pesticide and liquid impurities can be discharged separately, which is convenient for the staff to collect.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to these embodiments without departing from the principles of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
