Equipment for drying hydroxylamine hydrochloride

Abstract

The invention discloses equipment for hydroxylamine hydrochloride drying, and relates to the technical field of hydroxylamine hydrochloride drying, the equipment comprises a feeding cylinder, a pre-drying cylinder and a drying box, a material conveying inclined pipe is fixedly connected between the feeding cylinder and the pre-drying cylinder, and the end, away from the feeding cylinder, of the pre-drying cylinder communicates with the interior of the drying box; a liquid removing assembly is arranged on the feeding cylinder, a heating mechanism is installed on the pre-drying cylinder, and a material turning and drying assembly is arranged in the pre-drying cylinder. The liquid removing assembly comprises a liquid seepage end arranged at the middle end of the feeding cylinder, an outer cover is fixedly installed at the end, close to the liquid seepage end, of the outer wall of the feeding cylinder, a driven shaft is arranged in the feeding cylinder, and a material pressing twisting piece is fixedly installed on the circumferential outer wall of the driven shaft. In the rotating process of the material pressing twisting pieces, materials can be downwards transmitted, and the materials and the inner wall of the seepage end are extruded, so that a good filter pressing effect is achieved, and good liquid removal treatment can be carried out on hydroxylamine hydrochloride which is seriously deliquesced.

Description

technical field [0001] The invention relates to the technical field of drying hydroxylamine hydrochloride, in particular to a device for drying hydroxylamine hydrochloride. Background technique [0002] Hydroxylamine hydrochloride is an inorganic substance, mainly used as a reducing agent and imaging agent, used in the preparation of oximes in organic synthesis, and also used as a raw material for the synthesis of anticancer drugs, sulfonamides and pesticides. Hydroxylamine hydrochloride is easy to deliquesce, and it is easy to deliquesce due to improper protection during storage and transportation, and it needs to be dried before it can be used. [0003] After searching, the Chinese utility model patent whose publication number is CN211717108U discloses a kind of equipment for drying hydroxylamine hydrochloride, which includes a bottom plate and a separation chamber. A drying chamber, the top of the drying chamber is installed with a connected separation chamber, the separ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned invention has the following disadvantages: the above-mentioned patent directly adds the material to the interior of the device through the nozzle, making it contact with hot air to achieve the purpose of drying. , more serious deliquescence phenomenon is prone to occur, which makes the water content in the material larger, and the drying efficiency of direct hot air is low. Thereby further reducing the drying effect, so a kind of drying equipment is urgently needed now to dry the seriously deliquescent hydroxylammonium hydrochloride
