Description

TECHNICAL FIELD

[0001] The utility model belongs to silica gel raw material mixing production technical field especially relates to a silica gel raw material mixing reaction equipment. BACKGROUND

[0002] The moisture in the moisture-proof package is adsorbed by the drying agent to delay the increase of the water content of the packaged goods, thereby inhibiting the survival of microorganisms and weakening chemical reactions, photolysis reactions and enzymatic reactions, realizing mildew-proof, moisture-proof, rust-proof and antioxidant packaging, and achieving the purpose of prolonging the shelf life of products. This effective measure has been widely used in scientific research, production and daily life. Silica gel drying agent is a kind of high-activity adsorption material, and the main component is silicon dioxide, which is a kind of high-activity adsorption material. The reason why silica gel can absorb water is that the silicon hydroxyl group on the surface of silica gel can form intermolecular hydrogen bonds with water molecules, so it can adsorb water and play a drying role. The silica gel drying agent is usually prepared by reacting sodium silicate with sulfuric acid, melting the raw material sodium silicate into a liquid, and carrying out a series of post-treatment processes such as filtration and dilution. In the existing production process of silica gel drying agent, the raw materials cannot be fully and uniformly mixed in the mixing process, resulting in low mixing efficiency. For example, in the patent No. CN210846219U disclosed a kind of raw material stirring device for silica gel production, including stirring barrel, first stirring shaft is rotationally connected to the top of stirring barrel, hollow box is welded to the inner wall of the top of stirring barrel, and the box is rotationally connected with the first stirring shaft, a plurality of equidistantly distributed broken blades are welded to the outer circle of the end of the first stirring shaft extending into the box, a conical disc is rotationally connected with the first stirring shaft below the broken blade, and the conical disc is welded to the inner wall of the box, the conical disc is arranged in the box to help the powder-like raw materials to be discharged, and the broken blades are welded to the outer wall of the first stirring shaft, so that the powder-like raw materials added into the box are further crushed, to avoid the agglomeration of the powder raw materials directly entering the stirring barrel, resulting in insufficient stirring. However, when the barrel is stirred, the raw materials in the middle of the barrel along the radial direction cannot be mixed with the raw materials on the outside, resulting in insufficient mixing of the raw materials and low efficiency, which reduces the use efficiency of the equipment.
