[Dehydration Equipment for Plastic Recycling Granulation Lines] Shaking and Blowing Machine Product Introduction
—The final chapter in the process of removing moisture from the noodles, achieving deep dehydration through mechanical shaking and air knife blowing.
Core positioning:The shaking water blower is specially designed for"Underwater strip pulling" or "water ring strip pulling" pelletizing processThe designed combined dehydration unit. It is located in...Between the pelletizer and the vibrating screen or pneumatic conveying system,pass"High-frequency mechanical vibration" and "powerful cross-shaped air blades"The combined effect of these factors will cause the adhesive residue to adhere to the surface of the plastic strip.Most of the free water is forcibly stripped off and blown away.This significantly reduces the amount of water entering the pelletizer, therebyThis reduces the load on the subsequent centrifugal dryer (water blower), lowers overall energy consumption, and improves the dryness of the final particles.。
I. The Core Role of the Shaking Strip Blower in the Granulation Production Line
In the water-jetting process, the plastic strips drawn from the water tank have a large water film adhering to their surface. If they are directly fed into the pelletizer, it will cause:
The pelletizer is overloaded:A large amount of moisture is introduced into the pelletizer, increasing the resistance and energy consumption of its rotating parts, and may affect the pelletizing accuracy.
The subsequent drying process will be extremely stressful:All moisture must be processed by a centrifugal blower at the end, which greatly increases its heat consumption and the difficulty of dehydration.
Water stains remain on the surface of the particles:Even after passing through a water blower, the dense moisture introduced in strips can still cause uneven drying of the particle surface.
Limited production efficiency:To wait for the moisture to evaporate or to worry about incomplete drying, the speed of pulling the strips may be forced to be reduced.
The core value of the shaker-style water blower lies in:It is a dish"Pre-dehydration" processIt actively and efficiently removes most of the free water before pelleting, achieving moisture..."Segmented governance"This optimizes the energy efficiency and performance of the entire dehydration system.
II. Core Product Design and Technological Advantages
We adoptThe dual dehydration principle of "mechanical shaking + air knife stripping"This enables efficient pre-dehydration.
1. High-efficiency mechanical vibration system:
High-frequency low-amplitude vibration device:Plastic strips pass through one or more groupsHigh-frequency, low-amplitude vibrating elastic rollers or gridsThis specific frequency of mechanical vibration energyEffectively break the surface tension of the water filmThis causes the water droplets that have condensed on the surface of the plastic strip to be shaken apart and detached.
Adjustable amplitude/frequency:The vibration frequency and amplitude can be adjusted according to the thickness, speed and material (such as the different hardness of PP and PE) of the material (strips) to achieve the best water shaking effect without affecting the continuity and shape of the strips.
2. High-powered cross air knife system:
Multi-angle high-pressure air knife:After the shaking area, setStrip air knives arranged vertically or horizontallyThe wind blades sprayed out.Filtered compressed air at room temperature or low temperature, forming a"Air curtain wall"。
