Hydraulic Screen Changer-pulse Backflush Screen Changer 

The new high-pressure pulse backflush screen changer is the latest product developed by Deao of self-owned Chinese invention patent and international invention patent. There 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.

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%.

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.

12 months with proper operation by user, all the spare parts shall be replaced free of charge under guarantee period, fee for transportation and packing will be borne by users.
