Description

Filter for extruder

Technical Field

The utility model relates to a filter technical field for the extruder specifically is filter for extruder.

Background

In the process of plastic extrusion, after long-time plasticization and heating of plastic melt, decomposition residues can be generated in the melt, and impurities in raw materials enter an extruder head, so that a flow channel can be blocked, and plastic products have defects and even can not be normally produced: in order to filter impurities and enable pure melt to smoothly enter and be extruded into the shape, a filter screen is usually arranged between a picea wilsonii head and an extrusion molding machine head and used for preventing the impurities and the impurities from entering the extrusion molding machine head and continuing extrusion time, the impurities on the filter screen are gradually accumulated to cause pressure rise of the machine head and flow reduction, at the moment, the die head needs to be detached, the filter screen needs to be cleaned and replaced, the temperature needs to be increased again, blanks need to be pulled to be normally produced and extruded, the whole operation process is few dozens of minutes and many hours, raw material loss, energy waste and production cost increase are caused

The filter replacing device for the patent No. CN213137746U extruder effectively solves the problems of raw material loss, energy waste and production cost increase caused by the fact that the existing extruder needs to be stopped all the time when the filter screen is replaced; the technical scheme who solves is, drum including the level form, the drum left end is globular, there is vertical annular section of thick bamboo in the globular cavity of drum left end, annular section of thick bamboo outer fringe face is globular, the outer fringe of annular section of thick bamboo constitutes the ball pivot structure with the contact of spherical cavity inside wall, the filter screen is all installed in the cover of annular section of thick bamboo both ends, there is the plectane rather than coaxial in the annular section of thick bamboo, plectane outer fringe face and the contact of annular section of thick bamboo inside wall, the plectane can be along the annular section of thick bamboo horizontal slip, annular section of thick bamboo lower extreme has vertical play feed cylinder, it runs through the drum lateral wall and arranges the drum lower extreme in to go out the feed cylinder lower extreme, there is vertical pivot annular section of thick bamboo upper end, the pivot upper end runs through the drum and arranges the drum outside in, there is the rectangle piece on the drum, it has the pin to run through on the rectangle piece, the pin other end runs through the pivot.

The device realizes switching the filter screen of an annular section of thick bamboo both sides through annular section of thick bamboo and inside circular baffle, the realization is cleared up the filter screen, but adopt this kind of mode, a filter screen is located the outside always, collect up the dust, direct work after the switching gets into, can influence the quality of product, it is comparatively complicated to switch the mode simultaneously, the operation is inconvenient, simultaneously the round platform of the inside plectane of the device is protruding to form the gap with the annular arch in laminating back top easily, lead to the raw materials to remain inside, pile up for a long time, also produce easily and adhere to, cause the jam, for this reason, we disclose filter for the extruder.
