Description

Technical Field

[0001] This utility model relates to the field of vacuum drying technology, specifically a vacuum drying device equipped with feed protection. Background Technology

[0002] Vacuum drying is a drying technology carried out in a low-pressure environment. Under normal atmospheric pressure, the boiling point of water is 100℃, but in a vacuum environment, the air pressure is reduced, and the boiling point of water is also reduced. This allows the moisture in the material to evaporate quickly at a lower temperature, avoiding the impact of high temperature on the quality of the material. It is particularly suitable for heat-sensitive substances, such as pharmaceuticals and vitamins in food. The vacuum environment reduces the number of gas molecules, allowing the water vapor formed after the moisture evaporates to diffuse more quickly from the surface of the material into the surrounding environment, thus accelerating the drying speed and improving drying efficiency. Vacuum drying equipment has various feeding methods. Common feeding methods include gravity feeding, which uses the material's own gravity to allow it to fall naturally from a high-level silo or storage container into the vacuum drying equipment through pipes or chutes.

[0003] Existing vacuum drying equipment generally has an internal stirring structure to increase the drying effect during operation. However, during feeding, the direct impact of the material on the internal structure of the drying equipment increases wear, which will shorten the service life of the equipment and reduce its practicality.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the vacuum drying device equipped with feed protection:

[0019] 1. The device is equipped with a support mounting block and a support buffer baffle. When the device is working, the material is introduced into the protective shell through the feed pipe. The material will then fall on the surface of the support buffer baffle, which will cushion the material and prevent damage to the internal parts.

The upper surface of the protective shell 1 is through which the feed pipe 2 is installed, and the lower surface of the protective shell 1 is through which the discharge pipe 3 is installed. The vacuum pump 4 is fixed on the upper surface of the protective shell 1, and the heating rod 5 is installed on the outer surface of the protective shell 1. The feed pipe 2 and the protective shell 1 are offset from the axis. The heating rod 5 is arc-shaped and evenly distributed on the outer surface of the protective shell 1. When using this device, the material is first introduced into the protective shell 1 through the feed pipe 2. At this time, the material will fall on the surface of the support buffer baffle 10. The support buffer baffle 10 reduces the impact force, thereby preventing damage to the internal parts of the device.

[0030] A drive motor 6 is fixedly connected to the upper surface of the protective shell 1. A cavity is provided inside the protective shell 1, and a stirring cylinder 7 is installed on the top surface of the cavity. An agitator blade 8 is fixedly connected to the lower outer surface of the stirring cylinder 7. The upper end of the stirring cylinder 7 penetrates the upper surface of the protective shell 1.

The agitator blade 8 is symmetrically arranged about the axis of the stirring cylinder 7. Inclined blades are provided on the surface of the agitator blade 8. The support mounting block 9 and the supporting buffer baffle 10 are rotatably connected. A spring is connected between the supporting buffer baffle 10 and the protective shell 1. The supporting buffer baffle 10 rotates relative to the support mounting block 9 to facilitate the material falling. Then, the supporting buffer baffle 10 is pulled by the spring on its surface to rotate and reset. The material enters the material dispersion disc 12 for collection.

[0031] Two support mounting blocks 9 are fixedly connected to the inner wall of the cavity of the protective shell 1. A support buffer baffle 10 is set between the two support mounting blocks 9. The material dispersion mechanism includes a limiting fixing frame 11, which is fixed to the inner wall of the cavity of the protective shell 1. A material dispersion disk 12 is fixed between the limiting fixing frames 11. A guide pusher plate 13 is fixed to the outer surface of the upper end of the stirring cylinder 7. A discharge guide pipe 14 is installed through the lower surface of the material dispersion disk 12.

[0032] The inner wall of the cavity of the protective shell 1 is provided with a material dispersion mechanism. The material dispersion disc 12 is installed through the limiting and fixing frame 11 and the material is guided to the discharge guide pipe 14 through the guide pusher plate 13. The material dispersion disc 12 is designed as a disc and has grooves on its surface. The inner wall of the grooves of the material dispersion disc 12 is designed to be inclined. The guide pusher plate 13 is distributed circumferentially on the outer surface of the stirring cylinder 7. The stirring cylinder 7 penetrates the surface of the material dispersion disc 12. The discharge guide pipe 14 is arranged in a circumferential array. The driving motor 6 drives the stirring cylinder 7 and the stirring blade 8 to rotate, which facilitates the stirring blade 8 to stir the material and increases the processing effect. Finally, the material is discharged from the discharge pipe 3.

[0033] Working principle: When using this vacuum drying device with feed protection, the material is introduced into the protective shell 1 through the feed pipe 2, so that the supporting buffer baffle 10 buffers the raw material. Then the supporting buffer baffle 10 is pulled back by the spring, and the material is collected by the material dispersion plate 12, which facilitates the drive motor 6 to drive the stirring cylinder 7 and the guide push plate 13 to rotate, thereby pushing the material out from the discharge guide pipe 14, which facilitates the stirring cylinder 7 to drive the material stirring blade 8 to rotate, and finally the material is discharged from the discharge pipe 3, which increases the overall practicality.
