Description

Technical Field

[0001] This utility model relates to the field of wettable powder pulverizing devices, and more particularly to a wettable powder pulverizing device with a grading screen. Background Technology

[0002] As a core functional formulation in pesticides, coatings, and pharmaceuticals, wettable powders rely heavily on precise and controllable particle size distribution and excellent dispersion and suspension properties for their performance. High-quality wettable powders have a high suspension rate, and the pulverization process, by controlling particle fineness, specific surface area, and surface energy, directly determines the disintegration rate and stable suspension capacity of the powder in water, making it a crucial process affecting product performance.

[0003] The wettable powder pulverizing device mainly consists of a material conveying unit, a pulverizing component, and a screen assembly. The material is evenly fed into the pulverizing chamber by a screw feeder. The high-speed rotating grinding rod generates centrifugal force to impact and crush the material. The material is then sieved through screens of different aperture sizes to classify materials of different sizes.

[0004] Currently, wettable powder grinding devices can only grind materials of one particle size on a single machine. Workers need to use different machines to grind materials with different requirements, resulting in low work efficiency. To address this issue, a wettable powder grinding device with a grading screen is proposed. Utility Model Content

[0034] Reference Figure 1 , Figure 3 and Figure 5The screening assembly includes two screening screens 14. The screening screens 14 are used to classify and screen materials of different sizes to achieve the purpose of classification. Two fixing plates 16 are fixedly connected to both the front and rear ends of the screening screens 14. The function of the fixing plates 16 is to ensure that the materials fall evenly from the top. A fixing block 17 is fixedly connected inside the outer shell 23. A sliding groove 18 is opened inside the fixing block 17. A transmission column 21 is slidably connected inside the fixing block 17.

[0035] Working principle: The operator controls the cylinder 12 to pull the rotating shaft 11, causing the rotating shaft 11 to move backward, thereby causing the connecting column 9 to rotate on the rotating shaft 11. This, in turn, causes the connecting column 9 to rotate on the rotating shaft 8. During the rotation of the connecting column 9, the rotating shaft 8 is pulled, which in turn causes the telescopic rod 7 to retract on the fixed rod 6, thus reducing the distance between the two grinding rods 27. When a finer material is needed, the operator controls the cylinder 12 to push the rotating shaft 11, causing the telescopic rod 7 to extend on the fixed rod 6, thereby increasing the distance between the two grinding rods 27.

[0036] During the operation of the crushing device, the rotating shaft 20 is driven by the motor 22, which causes the rotating block 28 to rotate. As the rotating block 28 rotates, the transmission column 21 slides in the sliding groove 18. At this time, the transmission column 21 drives the fixed plate 16 to vibrate up and down, which causes the two screening screens 14 to move up and down reciprocally, causing the material at the top to shake and allowing the falling material to be fully screened, thereby achieving the classification and processing of materials of different sizes.
