Linear vibrating fluidized bed dryer

Principle:
    Material enters the machine from the feed inlet. Under the action of vibration force, the material is thrown forward along the horizontal direction and moves continuously. Hot air passes upward through the fluidized bed to exchange heat with the wet material. The humid air is dedusted by the cyclone separator and then discharged from the exhaust outlet. The dried material is discharged from the discharge outlet.

Features of large-scale fluidized beds:

1. The output of a large-scale fluidized bed is high and can reach a processing capacity of 20-30 tons per hour.

2. Compared with the combined output of several small fluidized beds, the equipment investment of a large fluidized bed is smaller, the operating cost investment is *, the energy consumption is lower, the management and maintenance cost is low, and the investment in auxiliary equipment is small (such as: feeding equipment, the number of sets of electrical control cabinets, the size of the equipment site, discharge packaging equipment, and equipment operators).

Structural differences:

1. Since the width of the mesh plate of the fluidized bed is above 2.6, the uniform distribution of materials is a great challenge. If bed deviation occurs in the bed body, material drying will first be affected (some are dried, some are not dried). * Long-term use under bed deviation causes great damage to the bed body, and in severe cases, bed body fracture may occur. After more than ten years of improvement by our company's engineers, from feeding to the overall improvement of the material movement path, the phenomenon of uneven material distribution has been completely and thoroughly solved.

2. Since the self-weight of the lower bed body reaches more than 13 tons, the structure of the bed body is very different from that of ordinary fluidized beds. Ordinary light fluidized beds generally directly vibrate the lower bed plate without reinforcement. The large-scale fluidized bed developed by our company adopts a frame-type structure in which the lower bed plate is welded onto an integral frame, thereby strengthening the overall bed body structure so that the service life of the entire equipment reaches more than 15 years. Multiple sections of reinforcement are used inside the bed body to greatly improve the overall rigidity of the bed body.

3. The damping form of the bed body is also much more reliable than before. Ordinary bed bodies use air cushions and rubber for vibration. For a bed body with a self-weight of 13 tons, these two forms can no longer be used. Our company, together with a domestic * spring factory, jointly developed a dedicated fluidized bed vibration spring. Its performance is good, and its working life is about three times longer than ordinary springs. The equipment maintenance interval is longer, and the use and maintenance costs for customers are lower.

Features:
● The vibration source is driven by a vibration motor, with stable operation, convenient maintenance, low noise, long service life, and convenient maintenance.
● High thermal efficiency, which can be 30% or more than that of general drying devices. The bed layer temperature is evenly distributed, with no local overheating phenomenon, uniform fluidization, and no dead corners.
● Good adjustability and wide adaptability. The material layer thickness, the moving speed inside the machine, and the uniform change of the full amplitude can all realize stepless adjustment.
● Little damage to the material surface, so it can be used for drying fragile materials; irregular material particles also do not affect the working effect.
● A fully enclosed structure is adopted, which effectively prevents cross-infection between materials and air, and keeps the working environment clean.
● When used for large-scale production of high-moisture materials, multiple units can be connected in series to meet user requirements (typical materials: such as polyacrylamide, etc.).
