Single column duplex screen changer for PERT floor heating pipes

The single column double-station screen changer is designed with two detachable filter stations on the plunger. When working, one filter station is inside the main body to filter the melt, and the other station is outside the main body for backup. When the impurities on the filter accumulate to a certain degree during the work, the screen needs to be changed, you can press the operating handle button on the hydraulic station to start the accumulator hydraulic station to change the screen.

The single pillar screen changer is designed as an integral cylindrical type, made of high temperature alloy steel, which has good performance in high temperature resistance and pressure bearing, and has double filter channels working alternately, so it is easy to change the screen quickly for production and maintenance. It has high wear resistance and high precision screen design. Under the pressure of 30-50MPa and temperature of 300-400℃, it will not affect its performance. Designed with lead material exhaust structure, no stopping to change the screen, no leakage of material, no interruption of production, can ensure that the product is not interrupted when changing the screen.

Single column screen changer structure features:

1、Adopt rigid sealing structure, reliable sealing without leakage.
2、Optimized material flow channel design, no dead angle and no stagnation.
3、Matching accumulator hydraulic station to realize fast net change, no stoppage, no material leakage, simple and quick operation.
4, can be customized with different specifications of single-screw extruder, twin-screw extruder, reactor to do direct connection.
5、It is especially suitable for the materials with frequent color change.

Single pillar screen changer technical parameters:

1、Working temperature: ≤350℃.
2、Working pressure: ≤50MPa.
3、Differential pressure: ≤20MPa.
4、Applicable melt viscosity: 100~40000Pa.s.
5、Heating method: electric heating/thermal medium heating.

hydraulic screen changer optional configuration

1、Highly corrosive working conditions - optional high corrosion-resistant material solutions.
2、Movable installation trolley, integrated accumulator hydraulic station and electrical control system, easy to maintain on site.
3、Integrated melt gear pump, mixer, drive valve, underwater pelletizing die head and other components connection and control, can provide a complete set of solutions.

Single column double-station screen changer is suitable for the production of high pressure products, especially for pipe, blown film, cast film, double line stretching, drawing, pelletizing. Almost all thermoplastics, etc. info@battemachinery.com
