Description

Paste centrifugal grinding device

Technical Field

The invention belongs to the field of crushing and grinding devices, and particularly relates to a paste centrifugal grinding device.

Background

The ointment is prepared by uniformly mixing the medicine, the medicinal materials and the extracts of the medicinal materials with a proper matrix to prepare a semisolid external preparation with proper consistency, and is easy to be coated on skin, mucous membrane and wound surface to play roles in protecting, lubricating and treating locally, for example, the ointment is prepared by adopting vaseline, paraffin and the like as matrixes. Ointments are commonly used for chronic skin diseases, and after percutaneous absorption of some drugs in ointments, they are classified into three categories, namely ointments, creams and gels, according to the characteristics of ointments.

Since most ointments act on the skin surface, the quality of the ointments directly feels the extent to which the skin absorbs the ointments, and therefore, the fineness of the ointments directly determines the absorption properties of the skin for ointments, and accordingly, the better the fineness of the particles, the better the absorption. The ointment is usually ground to a finer fineness after the ingredients are mixed. The common paste grinding device consists of a rotor and a stator, paste flows through a gap between the rotor and the stator, and relies on two conical surfaces to rotate relatively at a speed of 3000r/mm, so that the paste generates vortex and high-frequency vibration under the action of great friction force, shearing force and centrifugal force, and the paste is crushed, thereby playing a good role in mixing, homogenizing and emulsifying. However, such a grinding device cannot unify the fineness of the particles, and particles with larger fineness are inevitably doped in most of the particles with better fineness, thereby affecting the quality of the paste.

As the materials finally led out from the discharge port are ground and filtered layer by layer, the fineness is consistent, and the quality of the paste is improved.

Further, the grinding machine also comprises a group of pushing rings, wherein the pushing rings are positioned between the outer rotating shaft and the grinding cylinder, between the adjacent grinding cylinders or between the grinding cylinder and the inner wall of the cylinder body, the pushing rings are in sliding connection with the inner wall of the grinding cylinder, the upper part of the pushing rings is provided with a pushing rod, and the pushing rod penetrates through the upper part of the cylinder body and is positioned on the outer wall of the cylinder body. The pushing ring is used for scraping the materials adhered to the wall of the grinding cylinder, then the materials are ground again through the filtering holes of the grinding cylinder, and finally all the materials are led out from the discharge hole through the outer grinding cylinder, so that the grinding is more thorough.

Further, outer pivot upper portion outer wall be equipped with first external ring, the lateral wall of first external ring is equipped with the spout, the upper portion outer wall of every grinding vessel all is equipped with the second and connects the ring, the lateral wall of second connects the ring also is equipped with the spout, the upper portion inner wall of every grinding vessel is equipped with a set of inserted bar of locating in the spout. The inserted link can slide in the chute of the first or second external ring, so that when centrifugal force is generated, the grinding cylinder is subjected to radial acting force, and the inserted link slides from the chute of the first or second external ring, so that adjacent grinding cylinders want to be close to each other for grinding.

Further, the outer wall of the pushing rod is provided with threads, and a locking nut is arranged at the part of the pushing rod positioned outside the cylinder body. The pushing rod can be locked by a locking nut, and when the centrifugal rotation is carried out, the pushing rod is pulled to the top of the cylinder body and locked, so that the grinding is prevented from being influenced.
