Liquid nitrogen cooling device of synthetic resin preparation reaction kettle

Abstract

The invention discloses a liquid nitrogen cooling device of a synthetic resin preparation reaction kettle. The liquid nitrogen cooling device comprises a reaction kettle and a cooling box, a cover plate is installed at the upper end of the reaction kettle through screws, a feeding port is formed in the upper end of the cover plate, a motor is arranged at the upper end of the cover plate, and the outer side of a rotating shaft of the motor is sleeved with a connecting sleeve; a square rod is fixedly connected to the lower end of the connecting sleeve, a cross rod is fixedly connected to the outer side of the square rod, a first stirring rod is fixedly connected to the outer side of the cross rod, the cooling box is fixedly connected to the outer side of the reaction kettle in a sleeving mode, a flow channel is formed in the cooling box, and a supporting rod is fixedly connected to the lower end of the cooling box; a supporting plate is fixedly connected with the outside of the supporting rod. The liquid nitrogen cooling device of the synthetic resin preparation reaction kettle has the characteristics that the stirring reaction effect of the reaction kettle is better, and the coolingeffect of the reaction kettle is better.

Description

technical field [0001] The invention belongs to the technical field of synthetic resin production, in particular to a liquid nitrogen cooling device for a synthetic resin preparation reactor. Background technique [0002] Synthetic resin is a kind of artificially synthesized high molecular weight polymer. It is a resin that has both or exceeds the inherent characteristics of natural resins. ASTM D883-65T defines synthetic resins as solid, semi-solid or pseudo (quasi) solid organic substances with unrestricted molecular weight but often of high molecular weight, which tend to flow when stressed, often have a softening or melting range and break when broken It is in the shape of a shell, and the synthetic resin needs to be prepared in a reaction kettle. There are several problems in the use of traditional reactors: 1. The stirring effect of the stirring device inside the reactor is not ideal, which makes the reaction incomplete; 2. The cooling effect of the reactor is not go...

AI Technical Summary

Problems solved by technology

There are several problems in the use of traditional reactors: 1. The stirring effect of the stirring device inside the reactor is not ideal, which makes the reaction incomplete; 2. The cooling effect of the reactor is not good enough, so that the use of the reactor cannot reach the expected Effect, for this, it is necessary to design a liquid nitrogen cooling device for synthetic resin preparation reactor
