A sampling mechanism for a reaction kettle for producing diethyl allylmalonate

Abstract

A sampling mechanism for a reactor for producing diethyl allyl malonate relates to the technical field of reactor sampling, and comprises a reactor body, wherein an L-shaped support plate is fixedly provided on the upper outer wall of the reactor body, a horizontally arranged fixed tube is fixedly provided on the end of the L-shaped support plate, rotating cylinders are coaxially provided on both sides of the fixed tube, the open ends of the two rotating cylinders are arranged facing each other, the open ends of the two rotating cylinders extend into the two ports of the fixed tube respectively and are connected to the fixed tube in a rotatable sealing manner, a pressure control circular plate connected to the fixed tube in a sliding seal is coaxially provided in the rotating tube, and a horizontally arranged control telescopic cylinder is fixedly provided on the inner wall of the rotating tube. The present invention solves the problems that the existing sampling device for reactors for producing diethyl allyl malonate affects the normal progress of the reaction, the materials are easily contaminated, and the sampling process is cumbersome; the sampling process is inconvenient and the sampling cycle is long; the sampling process has safety risks; and the sampling material is wasted.
