TECHNICAL FIELD

[0001] The utility model relates to the field of silica production, especially to a superfine silica mixing collection and packaging device. BACKGROUND

[0002] Ultra-fine silica (Ultra-fine Silica) generally refers to high-purity silica (SiO2) powder with a particle size of nanometers to microns (generally ≤10 μm), which has a high specific surface area (up to hundreds of m 2 / g), excellent dispersibility, chemical inertness and thermal stability, and is widely used in high-tech industries and traditional material modification fields.

[0003] The existing superfine silica mixing collection and packaging field has the following technical bottlenecks. First, after the collection of superfine silica, the mixing device used is basically a single stirring structure device, which cannot avoid the agglomeration of superfine silica particles, affecting the dispersion performance of the product. In addition, during packaging, manual weighing or simple filling equipment is relied on, resulting in large fluctuations in single package quality and increasing subsequent use and deployment costs.

[0004] Therefore, in view of the poor mixing uniformity and large quality fluctuation after packaging of the traditional superfine silica mixing collection and packaging device, a superfine silica mixing collection and packaging device can be designed. SUMMARY

[0007] Further, the collection barrel is installed at the front end with a control cylinder; the screening net is provided at the left and right ends with a rim; the inner side of the collection barrel is fixedly connected with left and right symmetrical limiting slide ways; the rim is located inside the limiting slide ways and is in sliding connection with the limiting slide ways.

[0008] Further, the bottom end of the collecting barrel is designed as a concentrated bucket structure which is wide at the top and narrow at the bottom.

[0009] Further, the left and right ends of the collecting barrel are connected with the left and right end connecting ears of the barrel cover, and a telescopic air cylinder group is arranged between the left and right end connecting ears.

[0010] Further, the discharge channel and the feeding channel are provided with quantitative valves on the inner sides.

[0011] Further, the upper end of the transmission belt is provided with a baffle for positioning the packaging box of the ultrafine silicon dioxide.

[0012] Further, the control air cylinder piston rod is connected with the side wall of the screening net.

[0013] Beneficial effects are that: the utility model discloses a preliminary screening is realized through the reciprocating motion of the front end screening net, and the secondary mixing of the electric mixing part and the reprocessing assembly is combined, so that coarse particles are effectively removed, the uniformity of the material is improved, and the particle size distribution of the ultrafine silicon dioxide powder meets the high standard requirement.
