Abstract
Description
Technical Field
[0001] This invention relates to the field of drying equipment technology, specifically to a vibrating screen and fluidized bed drying equipment. Background Technology
[0002] A press is a core piece of equipment that achieves solid-liquid separation through mechanical pressure. It is mainly divided into screw type and hydraulic type, and is widely used in food juicing, oil extraction, and chemical residue dehydration. It features a compact structure and high separation efficiency. A fluidized bed dryer is a highly efficient thermal convection drying device. Hot air passes through the material layer from bottom to top, causing the particles to be in a suspended fluidized state. This results in a large gas-solid contact area, extremely rapid heat and mass transfer, uniform drying, high efficiency, and continuous automation. It is suitable for powdery, granular, and heat-sensitive materials, and common types include horizontal, vibrating, and multi-layer types.
[0003] Chinese patent CN119958231B discloses a vertical vibration fluidized bed, relating to the field of fluidized bed technology. It includes a mounting base, on the top of which a fluidized bed body is mounted via multiple vibration springs. A vibration motor is mounted on the side of the fluidized bed body. In this invention, starting the vibration motor causes the material to move from the upper and lower perforated plates towards the discharge port. The air inlet is connected to a hot air inlet, and the air outlet is connected to an exhaust pipe, allowing drying during material transport. Activating the leveling mechanism drives the stirring mechanism to agitate the material leaving the upper perforated plate, improving the drying effect. The agitated material has varying thickness uniformity. After leaving the upper perforated plate, it falls onto the lower perforated plate, where the leveling mechanism flattens the material with varying thickness uniformity, ensuring the material moves on the vertical plate with a uniform thickness and allowing for control of the material thickness. However, this device still has the following problems: The device is located inside the drying chamber, where there is a large amount of dust and a high temperature, making it difficult to use stably for a long time.

[0019] In this invention, the crushed material in the crusher 2 enters the vibrating screen 3 for screening.

Initially, the holes on the uppermost second screening plate 512 align with the holes on the first screening plate 511, while the holes on all the lower second screening plates 512 are not aligned with the first screening plate 511, thus closing the screen openings. At this time, the screening diameter of the material is equal to the screen opening diameter of the uppermost second screening plate 512 and the first screening plate 511. If it is necessary to reduce the particle size of the screened material, the operator pulls out the locking pin 523 in the locking hole 524 of the corresponding screening component 51 and all the screening components 51 above it to unlock the rotating handle 521. Then, the rotating handle 521 is rotated so that the holes on the second screening plate 512 align with the first screening plate 511. After the holes of the screening plate 511 are aligned, the locking pin 523 is inserted into another locking hole 524 that aligns with the locking hole 524 on the rotating handle 521 to fix the position of the rotating handle 521; then all the first discharge ports 532 on the upper side of the first screening plate 511 with corresponding apertures are connected to the interior of the crusher 2, and the first discharge ports 532 on the lower side of the first screening plate 511 with corresponding apertures are connected to the fluidized bed 4.
