A device for recycling organic silicon synthetic waste

Abstract

The invention belongs to the technical field of organic silicon production, and in particular to a device for recycling waste of organic silicon synthesis. The device comprises an upper seal head, a cylindrical barrel, a cone-shaped cylinder large in the upper part and small in the lower part, a residue outlet and a stirring module, wherein the stirring module comprises an air cylinder, support plates, connecting rods and arc-shaped sliding blocks; a group of support plates are arranged at intervals at the middle part of a push rod of the air cylinder; a group of connecting rods radially arranged along the support plates are arranged at outer rings of the support plates; one ends of the connecting rod are fixedly connected at one sides of the arc-shaped sliding blocks; elastic films are arranged in through grooves; one sides of the elastic films are fixedly connected with one sides of the through grooves; the other ends of the elastic films are fixedly connected with sliding plates; through notches are formed in the middle parts of the elastic films; and the sliding plates are used for controlling the closing or the opening of the notches. The device disclosed by the invention hasthe beneficial effects that the support plates are driven to move up and down by the push rod and when the arc-shaped sliding blocks slide to the cylindrical barrel, the sliding plates move outwards and the notches are opened, so that the flow path of organic silicon slag slurry is increased, the convection of the organic silicon slag slurry is more sufficient and the distillation efficiency of high-boiling point substances is improved.

Description

technical field [0001] The invention belongs to the technical field of organosilicon production, in particular to a recycling device for organosilicon synthetic waste. Background technique [0002] Organosilicon slurry is the waste produced during the synthesis of organosilicon monomers, especially methyl chlorosilane monomers. It is mainly composed of a large amount of high boilers and a small amount of unreacted silicon powder and copper powder brought out of the fluidized bed. , High boiler refers to the high boiling point polysilane mixture with silicon-silicon bond, silicon-carbon-silicon bond, silicon-oxygen-silicon bond, silicon-oxygen-silicon bond, silicon-silicon bond, silicon-carbon-silicon bond, silicon-oxygen-silicon bond, and a boiling range of 70.3-250 °C produced during the synthesis of methylchlorosilane monomer. . If this part of the material is exposed to the air, it will burn or form a strong acid mist or liquid. Therefore, if it is directly discharged, i...

Problems solved by technology

[0005] This technical scheme can steam out the high boilers, but this scheme uses the rotary stirring method to stir the organic silicon slurry, so that the temperature of the organic silicon slurry near the inner wall of the barrel is relatively high, and the convection of the organic silicon slurry is not sufficient, which restricts high The steaming efficiency of boiling matter is improved, and at the same time, some agglomerated materials cannot be broken, making it inconvenient to clean up
