Description
Technical Field
The utility model belongs to viscose filament yarn production field specifically is a be applicable to viscose filament yarn internal pressure formula filter core.
Background
With the innovation of the existing viscose process, the defects existing in the aspects of three-stage filtration and subsequent process filtration are more and more prominent, and the three-stage filtration refers to that viscose is subjected to three-stage filtration, and in use: 1. the filter period is shortened from 20-30 days to 11 days, i.e. the total filtering time is greatly shortened compared with the prior art. 2. The big filter element of the machine head is changed from 1 poplin +1 single velvet into 1 poplin. 3. The monofilament period is shortened from the original 14 days to 7 days and 4 days and gradually reduced to the current 2 days. 3. The number of the nozzle filter cloth is changed from the original 420 meshes to 120 (the aperture of the filter cloth is enlarged). 4. The nozzle has more impurities and poor spinnability, and the head changing rate is increased from 1.31 percent to 2.28 percent in actual production. 5. The filter element has more impurities. At present, the filtration before spinning adopted at home and abroad is a candle filter, the candle filter is composed of a filter sleeve and a filter element, the candle filter adopts a mode of filtration from inner pressure to outer pressure, but if an inner pressure type structure is adopted, the pressure and flow of the filter element need to be considered, if the filter hole of the filter element is blocked due to more impurities in viscose, the viscose in the filter element is accumulated too much and can not be filtered, and the filter element is cracked and leaks seriously, so that the function of filtering the viscose can not be achieved; the filtering direction of the viscose and the flowing direction form an angle of 90 degrees, the filtered viscose can not realize first-in first-out, so that the maturation degree difference is caused, and the spinnability is influenced to a certain extent.
For example, the utility model patent with the application number of 200420073299.5, the application date of 2004-07-07 and the name of 'spinning high-efficiency viscose filter' has the technical proposal as follows: the filter comprises an upper filter disc with a glue outlet nozzle, a lower filter disc with a glue inlet nozzle and a fastening device between the upper filter disc and the lower filter disc, wherein both the upper filter disc and the lower filter disc are provided with concave cavities, so that filter cavities are formed after the upper filter disc and the lower filter disc are folded, a filter screen is arranged in each filter cavity, the wall of each cavity of the upper filter disc is provided with a flow guide rib, and glue solution channels are respectively arranged among the glue inlet nozzle, the glue outlet nozzle and the filter cavities. The problem of current candle filter area is little, easily cause interior hourglass, can not make earlier filterable viscose flow out earlier is solved. Although the above patent document solves the problem that the first-in first-out cannot be realized, the filtering effect is still poor, and the filter element is easily blocked. And the internal pressure type filter element is directly fixed on the swing rod, if the filter element needs to be cleaned or replaced, the filter sleeve and the filter element need to be separated, and then the filter element and the swing rod are separated, so that the operation is troublesome.
