Mesh belt type melt filtration automatic screen changer

The mesh belt type melt filtration fully automatic screen changer adopts water-cooled sealing and controls the screen changing action by using melt pressure or time. The distance and speed of filter movement can be freely set. When the pressure or time reaches the set value, the control system automatically starts the heating rod at the outlet of the filter belt. After reaching the set temperature, the filter screen automatically moves, bringing impurities in the melt out of the screen changer with the filter screen. The pressure drops to the normal working value, and the control system automatically stops heating. The outlet end is water-cooled and sealed, and the net movement is fully automatic. The replacement of the mesh is fully automated, without the need for manual operation. The mesh belt moves smoothly, with small distances and no fluctuations in material pressure and flow, truly achieving constant pressure production.

Application scope of mesh belt automatic screen changer

1. The production of high-quality, long process products such as film coating, casting film, various types of wire drawing, sheet metal, sheet metal, chemical fiber, etc.

2. The production of high-precision products with strict requirements for pressure fluctuations.

3. Production of raw materials such as PP, PE, ABS, PS, PMMA, etc.

Performance characteristics of mesh belt automatic screen changer

1. The pressure during the screen replacement process does not fluctuate and has no impact on product quality;

2. Fully automatic network switching without manual operation;

3. No power grid, small space occupation, novel structure, convenient and simple installation;

4. Replacing the mesh without wear and tear, long service life, using internal heating, high thermal efficiency;

5. Detachable movable filter block (porous plate), convenient for maintenance and cleaning.

The hydraulic screen changer is an indispensable auxiliary equipment in the current rubber and plastic field. The function of the screen changer is to filter out impurities in the plastic melt, provide clean and impurity free plastic melt for subsequent processes, and ensure the quality of the final product. The common screen changers in the market can be divided into hydraulic plate screen changers, high-performance hydraulic double column screen changers, hydraulic double column ultra large area screen changers, manual screen changers, and mesh belt fully automatic screen changers and other products.
