Description

Rotary ventilation drying device

Technical Field

The utility model relates to the technical field of drying devices, in particular to a rotary type ventilation drying device.

Background

The structure of the existing rotary type ventilation drying device is as follows: the long cylinder body wall installed almost horizontally is provided with a plurality of small holes, the inner wall of the cylinder body is provided with a plurality of triangular shoveling plates along the circumference at equal distance, the end parts of the shoveling plates incline from the inlet side to the outlet side, and the shoveling plates are also provided with a plurality of small holes. The cylinder is provided with 2 groups of rollers which are respectively supported by 2 supporting riding wheels. The motor drives the large gear to drive the cylinder to rotate through the pinion after the motor is decelerated, and the rotary cylinder, the material inlet end and the material outlet end are all provided with sealing structures. The device body box is arranged outside the rotary cylinder body, and a partition plate is arranged in the device body along the axial direction and divides the dryer into a plurality of independent heating chambers. Each heating chamber is provided with a hot air inlet and outlet. And a dynamic seal is arranged between the rotary cylinder body and the device body to prevent the hot air from being short-circuited. A fine powder receiving hopper and a screw conveyer are arranged under the device body.

Since the hot air is blown only from the lower part of the shoveling plate where the material layer is retained, the hot air from the inlet to the outlet is blown into the cylinder from the side lower quarter of the material. Because of the dynamic sealing structure, the hot air is not short-circuited. The residence time distribution is narrow because the material in the dryer is moved forward by rotation, approaching plug flow. When the drying time needs to be prolonged, the residence time of the material in the dryer can be regulated by the outlet regulating baffle, and the continuous discharging is changed into intermittent discharging. Fine powder particles carried by tail wind are captured by a cyclone separator and then are emptied by an induced draft fan.

The cyclone type ventilation drying device has the following advantages:

1. since the object to be dried is always smoothly mixed during the drying process. Therefore, the machine is suitable for processing materials with strong adhesiveness, easy occurrence of drying difference and requirement of mixing motion all the time in the drying process.

2. For materials which are liable to undergo drying shrinkage during the drying process, such as polymer laminates, resins, synthetic rubbers, etc., the mobile layer can be averaged, so that a highly efficient drying process can be obtained.

3. For processed materials such as steamed rice, the appearance is not damaged in the processing process, and the uniform water content is maintained, so that the yield of a relative finished product is improved.

4. In the case of kelp, a plurality of pieces of a scaly processed material such as a fish processed product are overlapped at the time of inputting, but can be discharged in a single piece state to a product discharge port at the time of discharging a finished product. And ensures that an even drying is obtained.

In the practical use process, although a plurality of triangular shoveling plates are arranged on the inner wall of the cylinder body at equal intervals along the circumference, the small particle materials with strong adhesiveness still easily adhere to the intervals formed by the triangular shoveling plates, and the fluidity is not very high; because the long cylinder body is almost horizontally installed, the discharging time is slow for the discharging of the scaly large-volume processing raw materials by the rotation of the cylinder body.
