Description
Technical field
The present invention relates to a kind of chip filter, belong to the filter technology field of extruder or feed back machine.
Background technology
The extrusion mechanism of plastic extruder mainly is made of extrusion screw rod, machine barrel, hopper and head and template etc., and plastics plastify into uniform melt by extrusion system, and in this course under the build-up pressure, melt is extruded the head of screw extruder.Because be subjected to the influence of the cleanliness factor of raw material, solution needs to filter before extruding, filter adopts filter screen structure usually.Because screen pack often stops up, the draping frequency is higher, and the tired lock of operation is so some employings are shut down draping and do not shut down draping at present.Though and net exchanging device can adopt automatic draping, the filter screen cost is very high, and is subjected to hydraulic pressure and current affects, and it is bigger to fluctuate.The manual draping time is long, and labor intensity is big, and production cost strengthens, and especially is to reach the purpose of reusing filter screen, even with the filter screen burning of changing, causes environmental pollution.
At present no net is not shut down filter, has solved the problem of the big and production cost increasing of inefficiency, labour intensity that frequent draping causes.But its filter is made of filter conical tube, the filtration pore and the charging aperture that are arranged on the body; filtering pore is distributed in around the filter conical tube on the circumference; this filtration pore is inner small and outside big bellmouth orifice; conical screw is arranged in the filter conical tube; to accumulate in the impurity that filters pore aperture place by conical screw in rotation releases; make the inboard import of filtering pore be in clean clean conditions, realize the continuous filtration of not shutting down.But said structure not shut down its main vital part of filter be the filter conical tube; because the filter conical tube has certain thickness; in filtration, need bearing certain pressure; therefore the filter conical tube is made by metal material; several filtration pores must be made by machined on the filter conical tube; make the filter conical tube reach 60 order to 100 purpose filter openings per square inch; usually adopt modes such as digital control hole drilling or laser drill to process; process very difficult; not only processing cost is very high; and yield rate is low, also can't further improve the order number of filtration.Moreover, this kind structure filter conical tube is provided with the melt charging aperture, melt enters in the filter conical tube by plastic feed, because the material pipe of this plastic feed and extruder links, and melt has certain pressure, be anti-leak-stopping material, the filter conical tube must have certain radial tightening power with the extruder charging basket when being connected, therefore cause the stressed complexity of filter conical tube, make the filter conical tube occur breaking in early days, and lose filtering function.
Summary of the invention
The purpose of this invention is to provide rational in infrastructurely, easy to process, can cut down finished cost significantly, good filtration effect improves functional reliability and the chip filter in service life.
The present invention is that the technical scheme that achieves the above object is: a kind of chip filter, it is characterized in that: comprise the front end-plate end plate and be arranged on front end-plate and end plate between stacked filter plate more than ten, securing member is connected front end-plate and each filter plate with end plate, described each filter plate has cylindrical hole or taper hole, filter plate simultaneously radially is provided with plurality of grooves for plane, another side, adjacent two its plane of filter plate and the grooves of fitting constitute radially filter opening, and the inner aperture of described radially filter opening is less than the aperture, outer end.
Filter of the present invention adopt front end-plate, end plate and be arranged on front end-plate and end plate between stacked filter plate more than ten, because filter plate simultaneously radially has a plurality of grooves for plane, another side, adjacent two filter plate plane and the grooves of fitting can constitute radially filter opening, therefore can be combined into the filtration device structure of tubular by each filter plate, rational in infrastructure, compact.Groove on the filter plate of the present invention is open type processing, can adopt general process equipment processing, not only convenient processing, and reduce manufacturing cost significantly.The convenient control of the present invention groove size just can make filter reach the above filter effect of 100 orders per square inch, therefore can control the size of each filter plate upper groove according to different solutions, and is to reach rational filter effect, practical.The present invention is not provided with charging aperture on filter, make filter no longer be subjected to radially to connect stress influence, and filter only is subjected to melt pressure, therefore functional reliability and the service life that can improve filter.Chip filter of the present invention can be used for the filtration of extruding of various fat meltings, can use at various petroleum products, the extruder that is particularly suitable for plastics, terylene goods and feed back machine.
