Description

Drug ultrafine pulverization device

technical field

The utility model relates to a medicine ultrafine pulverization device.

Background technique

Superfine pulverization is a high-tech developed rapidly in the past 20 years. It can process raw materials into micron or even nanometer micropowder, and has been widely used in various industries. In view of the fact that pulverization is the basic processing technology in the production and application of traditional Chinese medicine, ultrafine pulverization has attracted more and more attention. Although this technology started late and there are relatively few varieties developed, it has revealed its unique advantages and vast potential. application prospects. the

Ultrafine pulverization technology is an important part of powder engineering, including ultrafine pulverization of powder raw materials, high-precision classification and surface activity changes. According to the size or granularity of raw materials and finished product particles, pulverization can be divided into coarse pulverization, fine pulverization, micro pulverization and ultrafine pulverization, which is a rough classification. It is worth noting that due to the differences in the use of ultrafine powders, preparation methods and technical levels in various countries and industries, the particle size of ultrafine powders is divided differently. the

The superfine pulverizer is generally a sieveless pulverizer. The particle size of the pulverized material is controlled by the airflow speed. The pulverized particle size requires 95% to pass through 0.15mm (100 mesh). It is generally used for special aquatic bait or aquatic open bait. Micro pulverizer, pneumatic conveying, and classifier are matched to complete. The crushing particle size of raw materials is very fine, which may show unexpected characteristics, but it also brings more problems, such as electrostatic adsorption, poor fluidity of materials, and large energy consumption for crushing, which increases production costs and affects processing operations. Relatively large, these adverse effects can be overcome by different methods (such as changing the feed processing technology). the

Superfine pulverization is achieved by means of impact, collision, shearing, grinding, and dispersion of materials. The extrusion crushing method in traditional crushing cannot be used for ultrafine crushing, otherwise it will produce granulation effect. When choosing a crushing method, it must be determined by the nature of the crushed material and the required crushing ratio, especially the physical and chemical properties of the crushed material have a great decisive effect, and the hardness and fracture of the material are more important. , for hard and brittle materials, the impact is very effective; while for Chinese herbal medicines, it is better to use grinding and shearing methods. In fact, any kind of crushing machine is not purely a certain crushing mechanism. Generally, two or more crushing mechanisms are combined for crushing. For example, the jet mill is crushed by the mutual impact and collision of materials; The high-speed impact mill is crushed by impact and shear; the crushing mechanism of vibratory mill, stirring mill and ball mill is mainly grinding, impact and shear; and the working process of colloid mill is mainly through the high-speed rotating grinding body and fixed grinding The strong shear, friction, impact, etc. generated by the relative motion of the body.

In the field of drug production, in order to ensure the dosage, the requirements for the size of the drug are very strict. The particles of some drugs are very small, which requires the crushing of drugs with larger particles to meet the requirements.

Detailed ways

Referring to Fig. 1, a kind of medicine ultrafine pulverization device, comprises tank body 2 that is fixedly installed on bracket 1, and feed tank 3 is fixedly welded on bracket 1, and the bottom of tank body 2 is provided with feed inlet 4, feed tank 3 and the feed port 4 are connected with a feed pipe 5, and a blower 6 is installed in the feed pipe 5; a blade 7 is installed in the rotation of the tank body 2, and a filter screen 8 is arranged above the blade 7, and the side wall of the tank body 2 The upper end of the tank body is provided with a discharge port 9 and is connected with a discharge pipe 10, and an induced draft fan 11 is installed in the discharge pipe 10; the bottom of the tank body 2 is provided with a miscellaneous material outlet 12.

The discharge pipe 10 is respectively provided with several feeding openings 13 .

Large particles of medicine are poured into the feed tank 3, and under the guidance of the blower 6, enter the tank body 2 through the feed pipe 5 and the feed port 4, and become fine particles under the continuous rotation of the blade 7, and then After being screened by the filter screen 8, the particles that meet the requirements pass through and are discharged from the discharge pipe 10 under the guidance of the induced draft fan 11, and then proceed to the next process of processing or finished product packaging. The medicine that is not pulverized in time then falls, and is discharged through the miscellaneous material outlet 12, and continues to be circulated in the feed tank 3 for the superfine pulverization process.
