Kongskilde presents its Air Wash and Venturi system
New technique for cleaning dry of crushed plastics
The idea behind the Air Wash of Kongskilde system is the secure solution for the combination of transport and separation of light particles, dust and impurities in crushed plastics, plastic pellets and other granular materials.
The content of light particles and dust in the raw always reduces the use of this material and the quality of the finished products. For this reason, Kongskilde sees in the Air Wash system with great potential. The new Air Wash system consists of components kongskilde, such as fans, rotary valves, cyclone and modular pipeline.
The new Air Wash is available as a modular solution, being possible installation in an existing production process. The transport of the material until the cleaning unit travels through a modular tubing system, whose design allows its adaptation to any solution in plant. Material being transported not passes through the fan of transport by which reduces the additional production of dust and fine, at the same time requiring less maintenance.
The Air Wash of Kongskilde system consists of 3 different models. These systems offer cleaning capabilities from 200-900 kg per hour. If you require higher capacities Kongskilde also has other solutions.
The capacity of the Air Wash system is up to 3,000 m3 of air per hour. This means that the aspiration made directly from a windmill will help cool both the mill and the aspirated material. For this reason, Air Wash technology helps to improve the functioning of the process.
Transport in continuous without moving parts
The system venturi for the transport of cuts, products of rejection and strips continuous is characterized by transporting the material through a duct without any obstruction or mechanical parts in motion.
The essential part of the system is its ITF venturi with diameters of 160 or 200 mm through connection, which offers a high capacity for the extraction of, for example, strips continuous cutting machines and rewinders.
Given that there are no surfaces punched in the system, the particles of the transported product cannot block any internal system area. Similarly, the absence of moving parts eliminates the risk of braided or jam in the flow of the material. Therefore the system is very suitable for use with light of low thickness materials that have tendency to block air with punched parts returns.
To achieve the optimal flow of transport, the system can be combined with fans Multiair or TRL ranges. The fan creates the air flow by the increase in pressure in the Chamber that surrounds the ITF venturi. At a certain point, the air passes through a small narrowing towards the exit of the venturi, then producing an aspiration throughout the entire line of transportation.
The inner diameter of the venturi is the same as the diameter of the conduit of transportation. However, the output of the venturi through is larger diameter to accommodate more flow at the side of exit of the venturi.
This system is designed without return of air, so that the fan does not increase the temperature of the air transport. Thus, air flow that should separate from the material carried on the aire-material tab is greater than the systems that use the return of the air.
The fan and the venturi are placed near the point of discharge of the system. This makes the entry of material into the system easier and not require any system of feeding. The material is simply sucked through one or more ducts and transported through the venturi to the point of download.
