Description

Technical Field

[0001] The utility model belongs to the technical field of Chinese medicinal material pulverization, and particularly relates to an ultrafine pulverization device for Chinese medicinal materials. Background Art

[0002] Chinese herbal medicine is a unique medicine used by traditional Chinese medicine to prevent and treat diseases. It is also an important symbol that distinguishes Chinese medicine from other medicines. China is the birthplace of Chinese herbal medicine. There are about 12,000 kinds of medicinal plants in China, which is not available in other countries. Chinese herbal medicine is applied in various forms, including decoctions made by decocting the medicine with water and removing the residue and leaving the juice, powders ground into powder, pills, ointments, wine, tablets, granules, injections, etc. Traditional Chinese herbal medicine grinding is mostly done manually by using grinding rollers to crush and grind the Chinese herbal medicine, which is not only time-consuming and labor-intensive, but also has poor grinding effect and the degree of grinding is not fine enough. Even some small powder grinders on the market have a rough grinding effect and low grinding efficiency when encountering some medicinal materials with high moisture content or high viscosity. Therefore, there is an urgent need for a Chinese herbal medicine ultrafine grinder with good grinding effect and high grinding efficiency.

[0003] To this end, a Chinese herbal medicine ultrafine pulverizer with the announcement number "CN213315471U" includes a quick-freezing chamber, a liquid nitrogen generator, a pulverizing chamber and a sealing cover, wherein a support frame is welded on the top of the liquid nitrogen generator, and the other end of the support frame is welded to the bottom of the quick-freezing chamber, an air supply pipe is connected to the top of the liquid nitrogen generator, and the other end of the air supply pipe is connected to the quick-freezing chamber, a feed port is connected to the side of the quick-freezing chamber, and the other end of the feed port is connected to the inside of the pulverizing chamber, and a sealing cover is provided above the quick-freezing chamber. By pre-quick freezing the Chinese herbal medicines that need to be ultra-finely pulverized, especially the Chinese herbal medicines with high moisture content or high viscosity, the physical properties of the Chinese herbal medicines become crisp and brittle, which is more conducive to fine pulverization, and then the Chinese herbal medicines are fully pulverized by the pulverizing paddle and the grinding wheel to improve the fineness of the pulverization, which is not only more time-saving and labor-saving than traditional manual and ordinary pulverizers, but also has high pulverization efficiency, and the pulverization effect of the Chinese herbal medicines is better and the fineness is higher.

[0004] However, for the above-mentioned Chinese herbal medicine ultrafine grinder, although liquid nitrogen is used to pre-quickly freeze the Chinese herbal medicine to make the physical properties of the Chinese herbal medicine become crisp and brittle, which is more conducive to its fine grinding, and then the Chinese herbal medicine is fully ground using a grinding paddle and a grinding wheel to improve the fineness of the grinding, there are still the following obvious defects during use: after the Chinese herbal medicine is quick-frozen with liquid nitrogen, ultrafine grinding takes a certain amount of time, and in the process of ultrafine grinding, the liquid nitrogen has a certain time effect on the quick freezing of the Chinese herbal medicine, so the grinding roller will fail to speed up the grinding of the Chinese herbal medicine, and there will still be a problem of Chinese herbal medicine adhering to the surface of the grinding roller.

A circulating feeding box 9 is provided on the other side of the outside of the box body 1 for circulating and re-grinding the filtered medicinal materials, which can filter and remove unqualified Chinese medicinal materials and transport them to the inside of the integrated ultra-fine grinding and grinding cylinder 3 for ultra-fine grinding, thereby improving the quality of ultra-fine grinding of traditional Chinese medicine. The output connection of the circulating feeding box 9 has a pipeline that passes through one side of the upper end of the integrated ultra-fine grinding and grinding cylinder 3, which can recycle the filtered Chinese medicinal materials and transport them to the inside of the integrated ultra-fine grinding and grinding cylinder 3 for ultra-fine grinding.

[0024] One end of the shaft 4 passes through the upper end of the box body 1 and is connected to the servo motor 11 installed at the end of the box body 1, driving the shaft 4 and the crushing blade 5 and the ultra-fine grinding roller 6 to rotate inside the integrated ultra-fine grinding cylinder 3 to perform ultra-fine grinding on the Chinese medicinal materials. A conical guide block 12 is fixed to one end of the shaft 4 located between the crushing blade 5 and the ultra-fine grinding roller 6, so that the initially crushed Chinese medicinal materials trough is transported to the surroundings by the conical guide block 12, and it is conducive to transporting it to the ultra-fine grinding cavity between the ultra-fine grinding roller 6 and the integrated ultra-fine grinding cylinder 3. A crushing bucket 13 is provided on the outside of the crushed blade 5, which can make the initially crushed Chinese medicinal materials fall downward on the surface of the conical guide block 12. It is evenly transported by falling all around, the upper end of the crushing bucket 13 is fixed to the upper end of the inner side of the integrated ultra-fine grinding cylinder 3, and a feeding pipe 14 is provided at the position of the crushing bucket 13 corresponding to the box body 1, which is beneficial for the Chinese medicinal materials to enter the integrated ultra-fine grinding cylinder 3 for preliminary crushing, and one side of the cleaning plate 7 is embedded and fixed with the outer wall of the integrated ultra-fine grinding cylinder 3, which is beneficial for the high-pressure gas to enter the air blowing cleaning effect, and one side of the cleaning plate 7 is vertically and evenly provided with air blowing holes 15, and a mesh plate is provided inside the air blowing holes 15 to prevent Chinese medicinal materials from entering the cleaning plate 7, and the air blowing holes 15 penetrate to one side of the inner wall of the integrated ultra-fine grinding cylinder 3, so as to realize the effect of high-pressure gas entering the integrated ultra-fine grinding cylinder 3 for high-pressure air blowing to clean the residue.
