Product in kind: Gnoss Automatic Rotary Melt Filter With the patented rotary filtration technology, the gneuß fully automatic melt filter is the highest standard of melt filters on the market today, with impeccable product quality,50l rotovap, cost-effectiveness, ease of operation and maintenance. The automatic melt filter consists of three main parts-inlet block, outlet block and filter disc. The filter screen is distributed in the annular part of the filter disc. When the melt flows through the filter screen,wiped film evaporator, the pollutant particles are intercepted and the pressure difference is slightly increased. By sensing the pressure change, the control system automatically rotates the filter disc to make it rise by 1-2 degrees. The dirty screen leaves the melt channel while the clean screen is fed into the melt channel with the effective filter area unchanged. As a result of this mode of operation, the filtration system runs continuously without interruption and the pressure remains constant. In the standard case, the maximum variation of the filter differential pressure is only 2 bar. Melt Filter Operation Schematic The following data is from a customer of gneuß. This customer produces PP stretch film. The thickness at the exit was 335 μm, after which the film was stretched to 150 μm. The extrusion line consists of a 90 mm single screw extruder with RSF75 fully automatic melt filter installed downstream of the extruder. The production capacity of the extrusion line is 330 kg/H with 40 μm filter screen. The film is continuously monitored by a thickness measuring device. Expand the full text The graph below shows the percentage of the relative roll width. The left axis shows the absolute film thickness in μm, and the right axis shows the maximum relative deviation from the set value of 335 μm. The base time for the melt filter was set to 180 seconds. Select this time setting so that you can see if the operating cycle of the filtration system has an effect on the membrane thickness. In theory, thin film distillation ,thin film distillation, there should be a change every 180 seconds or every 10 measurement intervals. Looking at these values on the graph, you can see that the graph above is marked with I. The film thickness is a maximum absolute deviation of +/-5 μm with an average of +/-3 μm, representing a relative deviation of +/-1.5 or +/-0.9%. Compared to the normal deviation of about +/-0.6% for other factors in the extrusion line, these figures are only minimally improved in the filtration system. Considering that this extrusion line does not have a gear pump installed downstream of the filtration system (which may inhibit pressure variations), these values are very good.  Welcome to carry out technical exchanges and program discussions with Binlian Science and Technology.
