Kneading device for preparing magnesium stearate

Abstract

The invention discloses a kneading device for preparing magnesium stearate. The kneading device comprises a supporting frame, a conveying cylinder is arranged in the middle of the supporting frame, a crushing column is movably arranged in the conveying cylinder, at least three crushing grooves are formed in the crushing column, a rotating shaft is arranged in each crushing groove, two sets of smashing teeth and spiral feeding teeth used for conveying materials are sequentially arranged on the peripheral side walls of the rotating shafts, a transmission mechanism comprises a driving gear and three driven gears meshed with the driving gear, the driving gear is fixedly installed at the middle axis position of the top of the crushing column, and the driven gears are fixedly connected with the tops of the rotating shafts in a one-to-one correspondence mode. According to the kneading device for preparing magnesium stearate, provided by the invention, through kneading between the kneading column and the crushing teeth, the kneading column and the crushing teeth are subjected to primary crushing, through combination of the spiral feeding teeth and the crushing teeth, stearic acid and magnesium hydroxide can be mixed, the crushing and mixing effects are relatively good, and subsequent processing is facilitated.

Description

technical field [0001] The invention relates to magnesium stearate preparation and processing technology, in particular to a kneading device used for magnesium stearate preparation. Background technique [0002] Recently, due to the shortage of masks due to the new crown epidemic, one of the reasons is that the outbreak of demand has led to insufficient raw materials, and magnesium stearate has gradually become the research object of mask materials due to its superior performance. [0003] Magnesium stearate is a white loose and non-sandy fine powder, which has a greasy feeling when in contact with the skin and is easy to stick to the skin. Used as a lubricant, anti-sticking agent, and glidant, especially suitable for granulation of oils and extracts. The granules made have good fluidity and compressibility, and their texture is very soft, which can fill and level Due to the pits on the surface of the granules, the fit between the granules becomes weaker after use, and they...

Problems solved by technology

[0005] Obviously, in order to ensure the formability of magnesium stearate processing, it is necessary to mix stearic acid and granular magnesium hydroxide. Generally, stearic acid and granular magnesium hydroxide need to be pulverized by a kneader Kneading, and uniform mixing, because the state of stearic acid and magnesium hydroxide fusion is not liquid, its mixing efficiency is relatively low, the kneading machine in the prior art uses a Z-shaped kneading paddle to knead, as authorized announcement No. is: " CN 104209044B " Chinese patent provides " a kind of experimental vacuum kneader stirring paddle ", and it needs the operation of long time just can reach comparatively ideal kneading efficiency, in a word, the weak point of prior art is, The kneading and crushing effect is poor, resulting in too long kneading time and low production efficiency
