Double plunger large filter cartridge hydraulic screen changer applicable working conditions and screen changing process

Dual pillar large filter cartridge hydraulic screen changer is widely used in chemical fiber, blown film, flat film, cast film production, pipe, sheet, wire, fiber manufacturing, pelletizing line, recycling, etc. It is suitable for melt temperature below 450℃, and the designed operating melt pressure does not exceed 40MPa. It can operate normally under 40MPa melt pressure. The applicable production output is 1.5-4.0 T/H. It can meet the production capacity of at least 2T/h under the single-plunger filtration condition (the melt pressure is slightly higher than that of the double-plunger working condition, about 0.5-2.0MPa).

dual bolt screen changer

The main body and plunger of the hydraulic screen changer with double plunger and large filter cylinder are made of high-quality alloy steel, which has undergone heat treatment and nitriding treatment. After nitriding treatment of the flow channel, it is mirror-polished. Polishing requires the use of abrasives of more than 800 mesh to polish to mirror-level grade or above. , with high finish and wear resistance; excellent sealing and durability can be achieved through rigid material face-to-face sealing by strictly controlling the gap between the body and the plunger.

polymer melt filter

The dual-plunger large filter cartridge hydraulic screen changer adopts a dual-channel filter cartridge design, which can achieve a large filter area and have higher pressure resistance; during normal production, dual-channel simultaneous filtration and filter replacement. One plunger pushes out the main body After replacing the filter screen, after the material is introduced and exhausted, it immediately returns to the working position, and then the other plunger is replaced alternately, which solves the production interruption or hollow particles caused by the introduction of air during the screen replacement process. The main body of the device is equipped with a physical positioning ruler. The operator operates the control handle of the hydraulic station, and performs basic operations on the upper and lower plungers of the screen changer alternately: push out the plunger--clean the silo--replace the filter screen--pull the plunger to the leading and exhausting position --After the exhaust is completed, the main body of the screen changer is completely pulled into the working position, and the electric control cabinet instrument transmits the temperature and pressure signals of the screen changer to the central control center to ensure the stable production.
