Description of Newly designed self cleaning screen changer for melt filtration

The new high-pressure pulse back flush 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 back flush 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.

Performance Characteristics of Newly designed self cleaning screen changer for melt filtration

1. Equipped with a strong pulse screen washing system (of self-owned patent ), screen washing online available, cleaning rate of the filtering screen up to 80%-95%, no production interrupt, more than 200 times of usage of the filtering screen (depending on the density of the screen),minimizing the screen cost..

2. Filtering area from 365 cm2 to10000 cm2, initiative internationally (international patent), advanced technology, already put into practical application.

3. Simple construction, reliable operation; Easy maintenance, lower running cost;

Automatic screen changing by hydraulic; Machine non-stopped with screen changing.

Application fields of Newly designed self cleaning screen changer for melt filtration

1. Applicable to all the kinds of plastic products. Especially 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. 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%.
