Existing vibrating fluidized bed dryers consist of upper and lower bed bodies, with a vibrating motor mounted on the shell and vibration-damping springs installed at the bottom of the bed body. A mattress is placed between the upper and lower bed bodies. Commonly used plates (perforated plates) are mostly punched plates with straight, oblique, or tongue-shaped holes. Due to limitations in punching technology, the mattress thickness is generally 2mm.
Existing vibrating fluidized bed dryers have the following disadvantages: ① Due to insufficient plate thickness, rigidity is poor, making it difficult to ensure flatness. This causes the plate vibration frequency to be out of sync with the vibrating motor, resulting in the plate malfunctioning. Both of these factors affect the smoothness and uniformity of material movement. ② During vibration, material easily leaks through the holes and detaches from the bed body.
To solve these problems: The mattress is designed as a series-connected strip mesh plate. The series-connected strip mesh plate includes: multiple parallel metal strips, each with multiple series rings at its lower end. Adjacent series-connected metal wires and metal strips connect and fix the vertically distributed strips of each metal strip in series. The series-connected mesh plate has high rigidity and good flatness, allowing for smooth material flow, which helps to improve the drying speed, while preventing material leakage in vibrating materials.
