Quick dehydration device for producing citrate plasticizers

Abstract

The invention discloses a rapid dehydration device for the production of citric acid lipid plasticizers, which comprises a tank body, a rotating wheel, a hopper, an air blowing device, a deflector, a sliding rail, a sliding sleeve, an elastic expansion device, a rotating disc, and a first dehydration device. A magnet, a second magnet and a dispersing device; the plasticizer is thrown out and hits the inner wall of the tank, so that the plasticizer is evenly contacted with the hot gas in the tank, and the dehydration efficiency is improved. The phases are staggered, so that the hot air evenly overflows into the tank, so that the amount of hot air per unit area is uniform, and the reciprocating swing of the deflector makes the plasticizer located on the deflector thrown out in an arc shape, thereby improving the plasticity. The contact effect between the chemical agent and the hot air, and the hopper on the rotating wheel throws the plasticizer at the bottom in the shape of a windmill, and the upper rotating wheel receives the plasticizer thrown by the lower rotating wheel. Continue to throw, thereby improving the contact efficiency of the plasticizer and the hot air again, and improving the dehydration efficiency.

Description

technical field [0001] The invention relates to the technical field of plasticizer production, in particular to a quick dehydration device for the production of citric acid lipid plasticizers. 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. Chinese 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] In the production of citrate plasticizers, the post-treatment of citrate plasticizers, especially the dehydration process, has a great influence on the product color, thermal stability and other indicators. In the existing production process, the dehydration operation is mostly conventional distillation dehydration, and the ...

AI Technical Summary

Problems solved by technology

In the existing production process, the dehydration operation is mostly conventional distillation dehydration, and the material is dehydrated under reduced pressure in the distillation kettle. Due to the long distillation time, the product color is light yellow to yellow, and prolonged heating will also cause some oil-soluble impurities to enter the finished product. , resulting in poor product thermal stability and low dehydration efficiency, which limits the production efficiency of plasticizers
