Disc dryer for drying hydroxylamine hydrochloride

Abstract

The invention relates to the technical field of hydroxylamine hydrochloride drying, in particular to a disc dryer for hydroxylamine hydrochloride drying, which comprises a processing box, an annular pipeline is fixedly connected to the inner wall of the processing box, a plurality of blowing holes are uniformly formed in the inner wall of the annular pipeline, and a support frame is fixedly connected to the inner wall of the processing box; a lead screw can be driven to rotate through rotation of a driving motor, the lead screw rotates to drive a rotating pipe and a plurality of fixed pipes to move through two bevel gears, meanwhile, the lead screw rotates to drive rotating fan blades to rotate, the rotating fan blades rotate to suck air, and sucked air can form warm air through two arc-shaped heating plates; warm air enters the fixed pipe through the hose, the connecting pipe and the rotating pipe and then is sprayed out of the spray head to dry the raw materials, the rotating direction of the fixed pipe is opposite to the air spraying direction of the spray head, and the spray head is located on the fixed pipe in a matched mode, so that the raw materials are efficiently stirred and dried, and the drying speed of the raw materials is increased.

Description

Background technique Hydroxylamine hydrochloride is a kind of colorless crystal, easy deliquescence, white chemical substance, is mainly used as reducing agent and developing agent, It is used in the preparation of oximes in organic synthesis, and is also used in the synthesis of anticancer drugs (hydroxyurea), sulfa drugs (trimoxazole) and pesticides (methomyl). The raw material, hydroxylamine hydrochloride, needs to be dried and formed by corresponding drying equipment during production. Through retrieval publication number is the Chinese invention patent of CN114017997A, discloses a kind of hydroxylamine hydrochloride drying device, It includes a drying cylinder, a filter mechanism is arranged above the inside of the drying cylinder,...

AI Technical Summary

Problems solved by technology

[0005] In the process of drying hydroxylamine hydrochloride, the patent cannot adjust the frequency of discharge, and thus cannot adjust the drying time of hydroxylamine hydrochloride. Because the particle size of hydroxylamine hydrochloride is inconsistent, it is not conducive to drying hydroxylamine hydrochloride particles of different sizes.
