The utility model relates to the technical field of titanium dioxide treatment, and discloses a premixing device for producing titanium dioxide through continuous acidolysis, which comprises a collecting base, a support frame body is arranged at the top of the collecting base, a support pipe fitting is arranged on the right side of the top of the collecting base, and a treatment barrel piece is arranged on the side surface of the support pipe fitting. A feeding assembly is arranged at the top of the treatment cylinder part, and an inner mixing treatment assembly is arranged on the inner wall of the treatment cylinder part. According to the premixing device for producing titanium dioxide through continuous acidolysis, by arranging the feeding assembly, titanium dioxide needing to be premixed is added from the feeding assembly arranged at the top, the titanium dioxide can be placed on the uppermost first sieve plate during adding, and screening treatment can be conducted through cooperation of the reciprocating assembly with the first sieve plate and the second sieve plate; it is ensured that the particle size of the entering titanium dioxide meets the requirement, and it is avoided that too large caked titanium dioxide is added into the treatment barrel to affect the internal mixing efficiency.

The utility model discloses a geological sample grinding and screening integrated equipment relates to geological sample detection technical field. Including work table, the work table top central part is provided with grinding mechanism, and grinding mechanism contains jar body, and the connection between jar body and work table, the jar body bottom central rotation is connected with rotating shaft, and rotating shaft outer wall fixedly connected with a plurality of equidistance connecting plates, and the one side of connecting plate rotatable connection has a plurality of equidistance grinding block, and the one side of connecting plate rotatable connection has first filter plate. The utility model discloses through the setting of grinding mechanism and filter mechanism, in the use process, first geological sample passes into the jar body through the feed pipe, then motor drive rotating shaft rotation drives connecting plate and grinding block rotation, and the sample on first filter plate is ground, and the particle size is smaller and enters the next layer and continues to grind, and the device can effectively reduce the grinding length, and improve the work efficiency through multistage grinding.

The present application belongs to the technical field of optical film opening agent, and particularly relates to a preparation method of silica opening agent for optical film, which comprises the following steps: S1, keeping the temperature of a reaction kettle A at 200-300 DEG C and the pressure at 0.3-1.0 Mpa, simultaneously injecting a water glass solution W1 and sulfuric acid F1 into the reaction kettle A, and keeping the pH at 0.5-2.0 to form a silica sol; S2, transferring the silica sol to a reaction kettle B, keeping the temperature at 15-25 DEG C, simultaneously emulsifying and dispersing, and adjusting the pH to 10-12, then simultaneously adding a water glass solution W2 and sulfuric acid F2 into the reaction kettle B, after the addition is completed, aging at 80-100 DEG C, adjusting the pH to 3.0-5.0, and forming a silica precipitate through aging; S3, washing the precipitate and then wet grinding; and S4, spray drying the slurry to obtain the silica. The silica prepared by the method has a large pore volume, a small particle size and a low conductivity, has good opening property and transparency in the field of optical film, and has been successfully applied in the field of optical film.

The utility model relates to the technical field of broken screening machine, and disclose a kind of broken screening machine of internal circulation, solve the existing broken screening machine without the ability of internal circulation, leading to material cannot be broken by multiple circulation, leading to the particle size of material crushing does not meet the requirement, its use effect is not good, it includes device main body, the bottom four corners of device main body are fixedly installed with support leg, one side of device main body is fixedly installed with support frame, one side of support frame is fixedly installed with servo motor, one side in device main body is equipped with broken plate, the upper portion of broken plate is rotatably installed with axle rod, and one side of broken plate is rotatably connected with the inside of one side of device main body by hinged link, and the lower portion of one side of broken plate is rotatably installed with spring rod;The broken screening machine has the ability of internal circulation crushing, can realize the multiple circulation crushing of material, ensure that the particle size of material crushing meets the requirement, has very good use effect.
