Magnetic-force material-pushing-type rapid decolorization device for producing epoxy soybean oil plasticizer

Abstract

The invention discloses a magnetic-force material-pushing-type rapid decolorization device for producing an epoxy soybean oil plasticizer. A first magnet in a rotating state alternately attracts and repels a second magnet, so that a movable rod drives a material pushing plate to make reciprocating movement, and therefore the decolorization effect and efficiency of epoxy soybean oil raw materials,hydrogen peroxide and alkali liquid are further improved; through a stirring function of stirring blades and a U-shaped mixing frame, the decolorization effect and efficiency are more obvious, and thegood practical effect is achieved; hydrogen peroxide swirls along the inner wall of a tank body through a hydrogen peroxide outer extension pipe and is injected into the inner lower side of the tankbody, the epoxy soybean oil raw materials are injected into the tank body through a feeding hopper, and therefore hydrogen peroxide swirling along the inner wall of the tank body can be quickly mixedwith the epoxy soybean oil raw materials; hydrogen peroxide evenly falls on the epoxy soybean oil raw materials in the tank body through dropping holes, the mixing efficiency is improved, and the decolorization efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plasticizer processing, in particular to a magnetic pusher type rapid decolorization device for the production of epoxy soybean oil plasticizer. Background technique [0002] Plasticizer is a polymer material additive widely used in industry. Adding this substance in plastic processing can make it more flexible, easy to process, and can be legally used for industrial purposes. Taiwan manufacturers use a common plasticizer DEHP (later detected DINP, DNOP, DBP, DMP, DEP, etc.) instead of palm oil to prepare a clouding agent that can also produce a thickening effect similar to that of an emulsifier. [0003] The existing traditional production process of epoxy soybean oil plasticizer mainly adopts the method of alkali refining and refining, which is refined with concentrated alkali and low temperature process. Affected by raw materials and processing conditions, the traditional process control conditions are...

Problems solved by technology

[0003] The existing traditional production process of epoxy soybean oil plasticizer mainly adopts the method of alkali refining and refining, which is refined with concentrated alkali and low temperature process. Affected by raw materials and processing conditions, the traditional process control conditions are not only to generate the main glycerol fatty acid In addition to the ester mixture, there are also various impurities in different quantities, such as phospholipids, proteins, pigments, water, etc. The existence of these substances will undoubtedly affect the epoxidation reaction and product quality, and the removal rate of impurities under traditional process conditions is relatively low. Low, and the traditional equipment removal method mainly uses activated carbon or silica gel to remove directly in the tank, resulting in poor decolorization effect of epoxy soybean oil, which cannot improve the decolorization effect, and there will be many impurities, which cannot be fundamentally depigmentation
