Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, and particularly relates to a drying device for aquatic veterinary drug raw materials. Background Technique

[0002] Veterinary drugs refer to substances (including veterinary drug feed additives) used for preventing, treating, and diagnosing animal diseases or purposefully regulating the physiological functions of animals. Veterinary drugs mainly include: serum products, vaccines, diagnostic products, microecological products, Chinese medicinal materials, Chinese patent medicines, chemical drugs, antibiotics, biochemical drugs, radioactive drugs, and external pesticides, disinfectants, etc.

[0003] Before producing Chinese medicinal materials into finished veterinary drugs, it is necessary to clean the veterinary drug raw materials to remove some impurities on the raw materials. After the raw materials are cleaned, it is necessary to remove the moisture on the raw materials so as to enter the next production process. The traditional drying method is natural exposure to the sun, which is not only inefficient but also easily affected by the weather environment. Therefore, people have invented drying devices to replace the traditional natural exposure.

[0004] The drying device generally consists of a drying box and a hot air conveying pipeline. After loading the raw materials into the drying box, the raw materials are dried by hot air. However, the materials are in a static state in the drying box, and the drying speed of the surface materials is faster than that of the materials inside and at the bottom. In addition, the drying method of the above drying device is single and the drying effect is not ideal. In addition, after the drying operation is completed, powdery impurities smaller than the raw materials and other impurities larger than the raw materials are mixed with the raw materials. However, the above traditional drying device cannot perform screening and impurity removal operations on the dried raw materials. Therefore, it is urgent to design a drying device for aquatic veterinary drug raw materials to solve the above problems. Content of the Utility Model

[0005] The utility model provides a drying device for aquatic veterinary drug raw materials with reasonable structural design to solve the technical problems existing in the known technology. The utility model can use infrared radiation and high-temperature gas in combination to improve the operation efficiency of material drying, and can stir the materials during the drying process to accelerate the drying effect and working efficiency. At the same time, it can perform screening and impurity removal operations on the dried materials.

[0006] The technical solution adopted by the present utility model to solve the technical problems existing in the known technology is as follows: An aquatic veterinary drug raw material drying device includes a drying cylinder structure fixedly connected with multiple groups of legs at the bottom. An inlet is provided at the upper part of the drying cylinder structure, and a feed hopper is installed at the inlet.

[0032] Working principle:

[0033] The material to be dried is put into the feed hopper 7, and the stirring motor 2 and the reduction box 3 work together to drive the stirring shaft 4 to rotate, and then drive the heating and stirring component 15 to rotate. The rotating heating and stirring component 15 can stir the material in the drying cylinder structure; during the stirring process, hot gas is introduced into the heating and stirring component 15 through the passage rotary joint 13, and then the material stirred by the heating and stirring component 15 is heated and dried; wherein, the hot gas flows into the inflation chamber 15-12 from the central tube in the passage rotary joint 13 and the air inlet pipe 15-9, and the hot gas in the inflation chamber 15-12 flows into the stirring tube mechanism, thereby stirring and After drying, the hot gas flowing through the stirring tube mechanism flows back to the reflux chamber 15-8 through the return air radial tube 15-5 and the reflux port 15-11. Since the reflux chamber 15-8 is connected to the reflux channel 15-7, the gas flowing back to the reflux chamber 15-8 flows back to the passage rotary joint 13 through the reflux channel 15-7, and is recovered and processed through the passage rotary joint 13. At the same time, the infrared heater 8 is used in conjunction with the hot gas introduced into the heating and stirring assembly 15, which further improves the operating efficiency of material drying. At the same time, under the action of the axial flow fan 10, the moisture generated during the drying process is discharged from the exhaust port 11 to the outside of the drying cylinder 6.

[0034] After the drying operation of the materials is completed, the discharge valve installed on the discharge hopper 16 is opened, and the materials fall from the discharge hopper 16 into the screening assembly 17 for screening and impurity removal operations. Among them, the vibration motor 17-4 can drive the upper screening plate 17-3 and the lower screening plate 17-7 to vibrate. During the screening process, impurities with a particle size larger than that of the veterinary drug raw materials slide onto the storage plate 17-5 and are temporarily stored, impurities with a particle size smaller than that of the veterinary drug raw materials fall into the second material receiving part 17-8, and the raw materials that have completed screening and impurity removal fall into the first material receiving part 17-6. After working for a period of time, the staff will take out and transfer the screened impurities and the screened raw materials.
