Resin production dehydration device

Abstract

The invention discloses a resin production dehydration device, and belongs to the technical field of resin solid raw material dehydration, the resin production dehydration device comprises a dehydration kettle body, the bottom of the dehydration kettle body is fixedly provided with a kettle base, the inner cavity of the dehydration kettle body is slidably connected with an inner kettle body, and the outer side wall of the inner kettle body is fixedly connected with a jacket heat exchange mechanism. According to the device, an inflation pipe feeds gas into an expansion air bag, so that the expansion air bag is unfolded to push an abutting arc-shaped block to move upwards, and the abutting arc-shaped block moves upwards to pull a hinge block to rotate around one end of a first connecting rod to drive a top flexible unfolding cover to expand and unfold upwards; the distance between the flexible unfolding cover and the liquid level of a resin raw material in the inner kettle body can be adjusted, the situation that the resin raw material splashes and adheres to the interior of the flexible unfolding cover to affect the exhaust effect is avoided, meanwhile, when the flexible unfolding cover is unfolded and contracted, the pressure of the inner kettle body can be adjusted through the change of the space of the inner kettle body, and the pressure in the drying kettle during drying and heating is effectively controlled; the regulation and control treatment requirements of heating and drying are met.

Description

technical field [0001] The invention belongs to the technical field of resin solid raw material dehydration, and in particular relates to a resin production dehydration device. Background technique [0002] Resin usually refers to an organic polymer that softens or melts after being heated. When softened, it has a tendency to flow under the action of an external force. It is generally a solid state organic polymer at room temperature. The resin raw material often absorbs a certain amount of water in a solid state due to storage environment problems. Molecules, which will affect the reaction effect during processing, and need to be dried and dehydrated. Generally, during dehydration, heat is used to wait for water molecules to become steam and be discharged. [0003] In the existing resin dehydration, when the dehydration kettle is used, it is inconvenient to adjust the pressure in the dehydration kettle, which affects the pressure control ability of the resin production. At ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the inconvenient pressure adjustment in the dehydration kettle, which affects the pressure regulation ability during resin production, and at the same time, because the heating reaction will affect the foaming of the resin, resulting in splashing to the bottom side of the kettle lid, resulting in resin at the bottom of the kettle lid Drying and foaming block the mouth of the gas pipe, which affects the normal exhaust of steam, and a dehydration device for resin production is proposed
