Imidazolidine feeding device

Abstract

The invention relates to the field of imidazolidine feeding, in particular to an imidazolidine feeding device. The imidazolidine feeding device comprises a reaction kettle, a material adding pipe, a material adding hopper, a material conveying and lifting mechanism and a feeding frame, wherein the material adding pipe is arranged at a manhole position at the upper end of the reaction kettle; the material adding hopper is arranged at the upper end of the material adding pipe and is fixed on the feeding frame; the feeding frame is arranged above and at one side of the reaction kettle; the material conveying and lifting mechanism is arranged on the feeding frame and is positioned at one side of the reaction kettle. The imidazolidine feeding device has the advantages of simple design and convenience in use; by the arrangement of the material adding pipe, the distance between the material adding pipe and the reaction kettle is prolonged; meanwhile, an insertion plate is arranged on the material adding pipe, so that harm by gas volatilized from the reaction kettle to personnel during material adding is prevented; the material conveying and lifting mechanism is used for conveying large-package materials to a position above the feeding frame; an electric hoist above the feeding frame is used for feeding the large-package materials into the material adding hopper, so that a feeding requirement can be met at a time, and the time and the labor are saved; the imidazolidine feeding device is safe and reliable, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of imidazolidine feeding, in particular to an imidazolidine feeding device. Background technique [0002] Imidazolidine is a white needle crystal with a melting point of 216-218°C. Slightly soluble in cold water, easily soluble in hot water, ethanol, methyl ethyl ketone, DMF and other organic solvents, also easily soluble in cold alkali solution. Pesticide intermediates, mainly used in the production of pesticide imidacloprid, synthetic intermediates of pesticide imidacloprid. In the past, the feeding of the imidazolidine reactor was to manually feed the original small-package materials from the manhole of the reactor lid. When the manhole cover of the reactor was opened, irritating gas would be volatilized, which was toxic, and the personnel would feed the material through the manhole. , will breathe this gas at close range, and the small packaging materials need to be put in many bags to meet the requirements, whi...

In the past, the feeding of the imidazolidine reactor was to manually feed the original small-package materials from the manhole of the reactor lid. When the manhole cover of the reactor was opened, irritating gas would be volatilized, which was toxic, and the personnel would feed the material through the manhole. , will breathe this kind of gas at close range, and the small packaging materials need to be put in many bags to meet the requirements, which is time-consuming and labor-intensive, and has certain hazards to human health
