Abstract
The invention discloses a filter screen for an extruding machine. The filter screen comprises a hollow cylindrical outer cylinder body and filter cylinders arranged in the hollow cylindrical outer cylinder body. An inlet is formed in one end of the hollow cylindrical outer cylinder body, an outlet is formed in the cylinder wall of the hollow cylindrical outer cylinder body, a filter cylinder mounting base is arranged at the other end of the hollow cylindrical outer cylinder body, a cavity communicated with the outlet is formed in the filter cylinder mounting base, and the filter cylinders comprise a first filter cylinder, a second filter cylinder and a third filter cylinder. The first filter cylinder, the second filter cylinder and the third filter cylinder are the same in structure and comprise a thread portion and a conical cylinder portion with a plurality of filter holes each. The diameter of the filter holes of the first filter cylinder, the diameter of the filter holes of the second filter cylinder and the diameter of the filter holes of the third filter cylinder decrease in turn. According to the mode, the filter screen for the extruding machine is simple and reasonable in structure and not prone to being blocked, and different filtering precisions can be selected according to needs.

Technical field
The present invention relates to filter technical field, particularly relate to a kind of screen pack for extruder.
Background technology
Plastic extruder is to make plastic melting under a kind of high temperature about 200 degree, again the plastics of melting are formed to a kind of equipment of required shape by mould, the goods of extruding are all continuous section bars, as pipe, rod, silk, plate, film, electric wire clad etc.Screen pack is the important component part in extruder, is used for filtering out the granule foreign in molten plastic, guarantees the quality of product.Existing a kind of typical filter device, comprises shell and cylindrical cartridge filter, but gap between cylindrical cartridge filter and shell is less, if run into larger particles impurity, granule foreign is easily stuck in gap, results in blockage.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of screen pack for extruder, simple and reasonable, be difficult for to stop up, and can have more and need to select different filtering accuracies.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of screen pack for extruder is provided, comprise: hollow cylinder outer cylinder body and the cartridge filter that is arranged on described hollow cylinder outer cylinder body inside, one end of described hollow cylinder outer cylinder body is import, the barrel of described hollow cylinder outer cylinder body is provided with outlet, the other end of described hollow cylinder outer cylinder body is provided with cartridge filter mount pad, described cartridge filter mount pad is provided with the cavity being communicated with described outlet, described cartridge filter comprises the first cartridge filter, the second cartridge filter and the 3rd cartridge filter, described the first cartridge filter, the second cartridge filter is identical with the 3rd cartridge structure, include threaded portion and the conical tube body that is provided with a plurality of filter bores, described the first cartridge filter, the aperture of the filter bores on the second cartridge filter and the 3rd cartridge filter is more and more less.
In a preferred embodiment of the present invention, between described the first cartridge filter, the second cartridge filter and the 3rd cartridge filter and filter vat mount pad, be threaded.
In a preferred embodiment of the present invention, between described cartridge filter mount pad and hollow cylinder outer cylinder body, be provided with sealing gasket.
In a preferred embodiment of the present invention, described the first cartridge filter, the second cartridge filter and the 3rd cartridge filter are all to adopt stainless-steel sheet to make, and wall thickness is 3 ~ 5 millimeters.
In a preferred embodiment of the present invention, described filter bores assumes diamond in shape, and a plurality of filter bores form mesh-structured.
The invention has the beneficial effects as follows: the present invention is for the screen pack of extruder, simple and reasonable, be difficult for stopping up, and can have more and need to select different filtering accuracies.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is that the present invention is for the structural representation of screen pack one preferred embodiment of extruder.
In accompanying drawing, the mark of each parts is as follows: 1, hollow cylinder outer cylinder body, 2, import, 3, outlet, 4, cartridge filter mount pad, 5, cavity, the 6, first cartridge filter, the 7, second cartridge filter, the 8, the 3rd cartridge filter, 9, threaded portion, 10, conical tube body.
The specific embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of screen pack for extruder, comprise: hollow cylinder outer cylinder body 1 and the cartridge filter that is arranged on described hollow cylinder outer cylinder body 1 inside, one end of described hollow cylinder outer cylinder body 1 is import 2, between import 2 and extruder barrel, by flange, be connected, the barrel of described hollow cylinder outer cylinder body 1 is provided with outlet 3, the raw material that process is filtered is from exporting 3 out, enter the inside of extruder, the other end of described hollow cylinder outer cylinder body 1 is provided with cartridge filter mount pad 4, described cartridge filter mount pad 4 is provided with the cavity 5 being communicated with described outlet 3, described cartridge filter comprises the first cartridge filter 6, the second cartridge filter 7 and the 3rd cartridge filter 8, described the first cartridge filter, the second cartridge filter is identical with the 3rd cartridge structure, include threaded portion 9 and the conical tube body 10 that is provided with a plurality of filter bores, space between conical tube body 10 and hollow cylinder outer cylinder body 1 is larger, granule foreign is difficult for being stuck between both spaces, be difficult for resulting in blockage, extend lasting service time of the present invention.
