Drying production line of chlorinated polyethylene

Abstract

The invention discloses a chlorinated polyethylene drying production line which comprises a hot air circulating oven, a hot air supply box and a vacuum transfer box, and the hot air supply box is connected with the hot air circulating oven through a fan; a material containing box is arranged at the upper end of the hot air circulation oven, a first electronic pneumatic valve is arranged at the bottom of the material containing box, the vacuum transfer box is located at the bottom of the hot air circulation oven, and a soft metal barrel is arranged in the hot air circulation oven and rotationally connected into the hot air circulation oven through a rotating mechanism. A plurality of independent cavities are formed in the soft metal barrel, and a valve device is arranged between every two independent cavities; according to the drying production line, the rotating mechanism and the structure that the multiple independent cavities are formed in the soft metal barrel are adopted, the problems that in the drying process of chlorinated polyethylene, wall sticking is likely to happen, and dry and wet materials are likely to be mixed are solved, and the drying production line is simple in structure, low in equipment cost and suitable for industrial production. The maintenance is simple.

Description

technical field [0001] The technical field of drying equipment for chemical products of the present invention particularly relates to a drying production line for chlorinated polyethylene. Background technique [0002] Chlorinated polyethylene is a modified chlorinated high polymer obtained by chlorination of high-density polyethylene. Its chlorine content is generally controlled at about 30-50%. The appearance of chlorinated polyethylene is generally white powder or granules. It decomposes into a rubber-like elastomer at a temperature above 170°C. In the preparation process of chlorinated polyethylene, drying is one of the left and right processes. Hot air is usually used as the medium for fluidized drying, that is, particles with moisture When the material is in contact with the hot air flow, since the water vapor pressure on its surface is greater than the partial pressure of water vapor in the hot air, the water vapor diffuses from the surface of the material particles i...
