Description

Technical Field

[0001] The utility model belongs to the technical field of hydrophobic equipment, and in particular relates to a silicon dioxide powder surface hydrophobic equipment. Background Art

[0002] Silica is a common inorganic nanomaterial with good hydrophobicity. Hydrophobic silica is a specially treated silica whose surface is modified to reduce or eliminate its affinity for water. It is widely used in many fields. The production of hydrophobic silica is achieved by mixing a hydrophobic agent and silica powder through a hydrophobizing device to form hydrophobic silica, which makes the silica have hydrophobic properties.

[0003] When the existing silica powder surface hydrophobizing equipment is in use, the hydrophobic agent and silica powder are poured into the tank body of the equipment, and then stirred and mixed to become hydrophobic silica. During the stirring process by the stirring blades, some powder and hydrophobic agent will adhere to the inner wall surface near the top of the tank body. At this time, the attached powder and hydrophobic agent are prone to uneven stirring and mixing, affecting the production quality of hydrophobic silica. Moreover, when the inside of the tank body is cleaned after stirring and mixing, a full manual cleaning method is required to clean the inner wall, which increases the operator's operating fatigue. For this reason, we propose a silica powder surface hydrophobizing equipment. Utility Model Content

[0033] The working principle and use process of this utility model:

[0034] When the utility model is in use, the silicon dioxide powder and the hydrophobic agent are put into the tank body 100 together for stirring and mixing, and then the driving motor 200 is turned on to drive the rotating rod 203 to rotate, and the rotating rod 203 drives the small gear 205 to rotate and drive the large gear ring 206 to rotate, and drives the L-shaped frame 204 to rotate, and the L-shaped frame 204 drives the vertical frame 209 to rotate, and the vertical frame 209 drives the rubber scraper 208 to rotate.

After the discharge pipe 101 is inserted into the inside of the circular hole 302, the inner wall of the circular hole 302 is squeezed by the discharge pipe 101 to increase the friction between the discharge pipe 101 and the discharge pipe 101, thereby fixing the protective tube 300. At this time, the protective tube 300 can prevent foreign matter from entering the inside of the discharge pipe 101. When discharging, the protective tube 300 can be removed according to the reverse principle mentioned above.
