Features of the pulse backflush screen changer
1, Filtering area from 365 cm2 to 10000 cm2, initiative internationally (international patent)
2, No need to change the screen, but backflush of rapid pulse by little clean material in the machine
3,Cleaning area of the filtering screen up to 80%-95%
4,No interrupt the product
5, The filtering screen can be used more than 100 times.(depending on the density of the screen)
PS:
It 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%.
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.
