New pulse backflush continuous screen changer
The new pulse backflush continuous screen changer is the latest product developed by Deao of self-owned Chinese invention patent and international invention patent. It is no need to change the screen, but backflush of rapid pulse by little clean material in the machine. It is a symbol of internationally advanced technology, and is especially applicable for the machines of waste recycling and granulating, and direct waste processing . It is applied in the process of medium and large production lines with the features of high precision filtration, large production flow, good stability, and high automation.
How to work
The Back-flush screen changer from our company is similar with the double piston screen changer,and it adds a back-flush cylinder which is connected with the double piston. screen washing on line available(A small amount of clean material flows in reverse under high pressure, rinse the dirty screen.
Application fields:
1. Applicable to all the kinds of
plastic products. specially in the recycling and granulation combined with high impurities, such as
PE/PP/PS/ABS/PET/PA/etc.
2. Applicable to the
production line of chemical fiber, rubber, collosol, adhesive, coating and finishing materials and other blending agent products, used for filtration of the material mixture.
3. The pulse backflush continuous screen changer has been applied in the United States PS
recycling machine. Its output is 1100kg/hr, filtration precision of 40-60 mesh, new screen pressure of 2.5Mpa, material pressure of 7.5Mpa after admixture. The material pressure reduced to 2.5 -2.7Mpa after strongly washing the filter, filter cleaning rate exceeds 90%.
