Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, and particularly relates to a rotary oven for producing powder aquaculture veterinary drugs. Background Technique

[0002] Veterinary drugs refer to substances used for preventing, treating, and diagnosing animal diseases or purposefully regulating the physiological functions of animals. Their production process is roughly the same as that of ordinary drugs, and the raw materials prepared during production need to be pulverized and dried. In order to improve the drying efficiency of materials, drying equipment is mostly used in the prior art to dry veterinary drug raw materials.

[0003] Drying equipment dries materials through hot air drying, and there are two types: horizontal and vertical. Most existing horizontal drying equipment uses a drum dryer, also known as a rotary dryer. Its structure usually includes a machine body, and an inclined drum is installed inside the machine body. In order to make the material contact with the hot air, it also includes a lifter plate arranged on the inner wall of the drum. The lifter plate can lift the material so that it can fully contact the drying air, and at the same time move the material forward, and finally collect the dried material from the other end.

[0004] During the actual working process, when drying materials with high humidity, it is necessary to reduce the rotation speed of the drum and increase the retention time of the material in the drum, thereby increasing the drying time to ensure that the material is completely dried. However, after reducing the rotation speed of the drum, the rotation speed of the lifter plate will also decrease, and the amplitude of the lifter plate turning over the material during frying will decrease, making the material unable to fully contact the drying gas. Moreover, due to the reduction of the rotation speed of the lifter plate, the conveying efficiency of the material in the drum will also decrease, easily causing the material to accumulate in the drum, further affecting the drying effect of the material. Content of the Utility Model

[0005] The utility model provides a rotary oven with a reasonable structural design for producing powder aquaculture veterinary drugs to solve the technical problems existing in the known technology. The utility model can efficiently dry and bake the raw materials for preparing veterinary drugs, and avoid the situation where the materials accumulate in the drum and the materials are not completely dried.
