Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceuticals, in particular to a colloid mill for pharmaceuticals. Background Art

[0002] The colloid mill is composed of stainless steel or semi-stainless steel colloid mills. The basic principle is to use high-speed relative motion between fixed and movable teeth. Except for the motor and some parts, all parts that come into contact with the material are made of high-strength stainless steel. In particular, the key dynamic and static grinding discs are reinforced, thus having excellent corrosion and wear resistance, ensuring that the processed materials are clean, hygienic and pure.

[0003] Since the existing colloid mill has no shielding on the feeding shell, dust and other impurities from the outside can easily enter the feeding shell, causing contamination of the material in the feeding shell, resulting in impurities in the ground fluid or colloidal raw materials, causing the product to be unqualified. In addition, when processing some relatively viscous materials or some powdery materials, these materials often adhere to the inner wall of the feed hopper and cannot enter the grinding disc, resulting in insufficient material grinding. Utility Model Content

[0004] The purpose of the present utility model is to provide a colloid mill for pharmaceutical use to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solution: a pharmaceutical colloid mill comprises a support box and a bucket cover, the top of the support box is fixedly mounted with a collecting box, the interior of the collecting box is rotatably mounted with a rotating shaft, the top of the rotating shaft is fixedly mounted with a grinding table, the top of the grinding table is fixedly mounted with a connecting sleeve block, the bottom of the rotating shaft is fixedly mounted with a driven wheel, two collecting frames are movably mounted on the inner side of the collecting box, the top of the collecting box is connected with a blanking cylinder, the end of the blanking cylinder away from the collecting box is connected with a feed hopper, the inside of the feed hopper is fixedly mounted with a grinding sleeve, the top of the support box is fixedly mounted with a driving motor, the output end of the driving motor is fixedly mounted with a driving wheel, the outer side of the driving wheel is sleeved with a transmission belt, the bottom of the bucket cover is rotatably mounted with a rotating disk, the interior of the rotating disk is fixedly mounted with a rotating knob, the bottom of the rotating knob is rotatably mounted with a connecting rotating column, the interior of the connecting rotating column away from the rotating knob is provided with a connecting sleeve groove, scraping rods are fixedly mounted on both sides of the connecting rotating column, and the interiors of the bucket cover and the rotating disk are both provided with a feeding trough.
