Description

Medical treatment medicine spiral vibrations drying equipment

Technical Field

The invention relates to the technical field of medicine drying equipment, in particular to medical medicine spiral vibration drying equipment.

Background

Drying techniques and equipment have a wide range of applications, and relate to the petroleum and chemical industry, the feed industry, the plastics and rubber industry, the wood industry, building material work, the food industry, the pharmaceutical industry and the like, and the drying techniques are techniques with properties of experimental science across industries and subjects. The field of petrochemical industry: according to incomplete statistics, the drying requirement of the petrochemical industry accounts for 70% of the market of the whole drying industry, and the investment of drying equipment in petrochemical equipment in China is large and the energy consumption is high. Petroleum contains a large amount of organic matters, hydrocarbons, oils, petroleum sludge and the like, the boiling points and the gasification heat of the substances are different, a plurality of petrochemical enterprises face a plurality of problems of technical equipment aging, high cost, environmental protection standard exceeding and the like, and some companies even generate secondary pollution. Petrochemical sludge drying is also a major problem faced by petrochemical enterprises, and almost every petrochemical enterprise is confused at present because of insufficient landfill amount and incapability of meeting environmental protection requirements. The field of petrochemical industry needs to find and develop a drying device and a drying method with high efficiency, low energy consumption and low cost. The field of feed industry: the feed industry is a very large industry, and China has become a relatively complete industrial system which is across departments and across disciplines and comprises the feed processing industry, the feed raw material industry and the feed additive industry after the development for more than 20 years. Drying equipment and technology are required to different degrees in the production process of feed raw materials and feed additives, and the drying technology is widely applied to the field of feed industry. The wood industry field: the wood contains a certain amount of water, and according to the difference of tree species, tree age and felling season, in order to ensure the quality and prolong the service life of the wood and wood products, proper measures must be adopted to reduce the water content in the wood, and in order to reduce the water content of the wood, drying equipment and a mode must be adopted to evaporate the water in the wood and leave the wood. The drying of the wood is an important link for guaranteeing and improving the quality of the wood, reducing the loss of the wood and improving the utilization rate of the wood. Meanwhile, wood drying is also the most energy-consuming process in the production process of wood quality. The food industry field is as follows: the important agricultural products except grains in agricultural production of fruits and vegetables are delicious, have rich nutrients, are main sources of vitamins, inorganic substances, carbohydrates and cellulose for people, are rich in vitamin A, carotene and the like in some fruits and vegetables, and the vitamin C in human diet is mainly obtained from the fruits and the vegetables. However, most of fresh fruits and vegetables have moisture content of more than 90%, and the fresh fruits and vegetables are rotten due to slight mishandling in the processes of picking, transporting, storing and transporting and selling, so that the drying treatment after the vegetables and fruits are picked is of great significance. At present, China has several different devices and methods in the aspect of medicine drying, and the devices and the methods have respective advantages and also have a plurality of defects. Drying by a boiling fluidized bed: the equipment is widely applied to pharmacy, chemical industry and food processing, and comprises an air filter, a boiling bed main machine, a cyclone separator or a bag-type dust collector, a high-pressure centrifugal ventilator, an operation table and the like. Because the dry materials have different properties, when the cyclone separator is matched with dust removing equipment, the materials with larger specific gravity only need to be selected. The disadvantages are as follows: the requirements on the dried materials are high, the effect is best when the particle size of the materials is generally required to be not less than 30 micrometers and not more than 4 millimeters, when a plurality of different materials are mixed together for drying, the gravities of the materials are best close to each other, otherwise, the phenomenon that the effect is not complete in drying is poor occurs; since the material dried by the fluidized bed is mixed back violently and the retention time of the material is not uniform, the material which is not dried is discharged out of the bed layer along with the product possibly. A drum dryer: wet material is delivered to a feed hopper by a belt conveyor or a bucket elevator, and enters a drier from a feed inlet, a main body of the rotary drier is a cylinder which is slightly inclined and can rotate, the material enters the cylinder and then is dried by being contacted with hot air passing through the cylinder in a downstream or upstream manner, and a dried product is discharged from the lower part of the other end. During the drying process the material moves under gravity from the high end to the lower end by means of the slow rotation of the drum. The disadvantages are as follows: the equipment has large volume, complex assembly and disassembly, small heat capacity coefficient, low heat efficiency, long retention time of materials in the dryer and large retention time difference among material particles. Rake drying: the rake type drying equipment is a domestic traditional drying technology and has a certain effect on drying various materials in the form of pulp, paste, particles, powder, fibers and the like. The transmission part of the rake type drying equipment adopts a cylindrical gear speed reducer which works stably and is durable, a main shaft adopts a solid shaft, the stable operation of the equipment is ensured, the dried material is added from the middle above the shell, the material moves back and forth in the axial direction under the stirring of the continuous rake teeth which rotate positively and reversely, the surface which is contacted with the inner wall of the shell is continuously updated, and the indirectly heated material is heated. The disadvantages are as follows: the structure is too complex, the cost is expensive, and because of intermittent operation, the drying time is long, and the stock yield is low; and the materials are not easy to be discharged and cleaned, so that the materials are not suitable for frequent exchange.
