A kind of tray dryer for drying hydroxylamine hydrochloride

Abstract

The invention relates to the technical field of drying of hydroxylamine hydrochloride, in particular to a disc dryer for drying hydroxylamine hydrochloride, comprising a processing box, an inner wall of the processing box is fixedly connected with a circular pipe, and the inner wall of the circular pipe is evenly provided with a plurality of The inner wall of the processing box is fixedly connected with a support frame; the present invention can drive the screw rod to rotate through the rotation of the driving motor, and the rotation of the screw rod drives the rotating pipe and the plurality of fixed pipes to move through the two bevel gears, and the screw rod rotates at the same time. Drive the rotating fan blades to rotate, the rotating fan blades can inhale air, and the inhaled air can form warm air through two arc-shaped heating plates. When drying the raw materials, since the rotation direction of the fixed pipe is opposite to the direction of the jet of the nozzle, and the nozzle is located on the fixed pipe, the efficient stirring and drying of the raw materials is realized, thereby improving the drying speed of the raw materials.

Description

technical field [0001] The invention relates to the technical field of drying of hydroxylamine hydrochloride, in particular to a tray dryer for drying hydroxylamine hydrochloride. Background technique [0002] Hydroxylamine hydrochloride is a colorless crystalline, easily deliquescent, white chemical substance. It is mainly used as a reducing agent and an imaging agent. It is used to prepare oximes in organic synthesis. It is also used to synthesize anticancer drugs (hydroxyurea), sulfonamides ( sulfamethoxazole) and pesticide (methomyl) raw materials, hydroxylamine hydrochloride needs to be dried and formed by corresponding drying equipment during production. [0003] After searching the Chinese invention patent with the publication number CN114017997A, a drying device for hydroxylamine hydrochloride is disclosed, which includes a drying cylinder, a filter mechanism is arranged above the interior of the drying cylinder, and a dispersion device is arranged below the drying c...

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.
