Abstract

The utility model relates to a plastic regeneration high-efficient filtering extruder head which pertains to devices used for forming thermoplastic materials. A filtering pipe bundle is fixedly arranged in an external cylinder of an extruder, each opening end of the filtering pipe bundle passes through an end plate and is fixed with the end plate; the end plate is inosculated with an outlet of the external cylinder of the extruder, a press cover of the extruder head tightly presses the end plate and is connected with a screw jaw of the external cylinder of the extruder, and a filter mesh is fixed on the inner wall of the press cover of the extruder head. The plastic regeneration high-efficient filtering extruder head of the utility model has reasonable design, simple structure, increased filter specific surface area and significant filtration effect, and the use of the device can greatly delay the time and the times of mesh cleaning, improve the production efficiency, reduce the production cost and have the advantages of convenient use, energy conservation and low cost.

Description

Plastic reclaimed high efficiency filter extruder head

Technical field

The utility model belongs to thermoplastic moulding device, particularly relates to a kind of plastic reclaimed high efficiency filter extruder head.

Background technology

Waste or used plastics is abundant in china natural resources, reclaims inexpensively, be national support project, and equipment investment is few, and production technology is simple, so China's reclaiming and utilizing waste plastics has " money " greatly on the way.The technics of reclaim of plastic waste amount is very big now in our country, estimates the output at 3,000 ten thousand tons, should have about 4,000,000 tons in 1 year.If be not used, will cause to environment " white pollution ".Use special-purpose Granulation Equipments, can produce market regenerated granule salable with waste or used plastics such as waste polyethylene, polypropylene by fragmentation-cleaning-heating plasticizing-extrusion forming process.But well-known, there are impurity such as dust, greasy dirt on the waste or used plastics surface, and these impurity are though through cleaning, still have residual.Utilize existing machinery equipment that waste or used plastics is added man-hour; because its filter area is little; these remaining impurities are in the process of plastic extruding pelletization; can stop up the screen pack of plastic extruding pelletization machine head, need frequent replacing screen pack in the production, cause screen pack short, replacement cycle weak point service time, not only lose time; reduce output; but also can cause significant loss, and the consumption that increases electric power, thus production cost strengthened.

Summary of the invention

The utility model is intended to overcome the deficiencies in the prior art, has designed a kind of plastic reclaimed high efficiency filter extruder head of simple and practical, easy and simple to handle, low power consuming high efficiency.

Plastic reclaimed high efficiency filter extruder head of the present utility model is to have fixedly mounted to filter tube bank in the extruder urceolus, each openend of filtration tube bank passes end plate and fixes with it, the outlet of end plate and extruder urceolus matches, and the head gland compresses end plate and links with extruder urceolus spiral shell and connects.

As further improvement of the utility model, described filtration tube bank is to coat the screen pack formation outside the filter tube excessively, and is having the filtrate through hole on the filter tube excessively.

As further improvement of the utility model, on the inwall of head gland, be fixed with screen pack.

Utilize this device, original plastic extruding pelletization unit need not be done any change, this device need only be got final product to be threaded with original extruder, and fuselage has prolonged 30cm.The plastic medium of fusion is mobile forward in extruder, and the filtration tube bank through this device remains in the impurity in the medium between the screen pipe, and cleaner medium continues to flow forward, and the screen pack of process head goes out extruder.Because the space of filtering between the tube bank is very big, can retain a certain amount of impurity, not as screen pack, a spot of impurity is only arranged, changes with regard to network blocking, thereby delayed time of clear net greatly.

The plastic reclaimed high efficiency filter extruder head of the utility model specific filtration resistance surface area, filter effect reasonable in design, simple in structure, that increase is remarkable, use this device, can delay the time of netting clearly and number of times greatly, improved production efficiency, reduce production cost, had advantage easy to use, energy-saving and cost-reducing, that cost is low.

Fig. 2 is that plastic reclaimed high efficiency filter extruder head A-A of the present utility model is to schematic diagram.

The specific embodiment

Plastic reclaimed high efficiency filter extruder head of the present utility model is to have fixedly mounted to filter tube bank 4 in extruder urceolus 1, each openend 6 of filtration tube bank 4 passes end plate 5 and fixes with it, end plate 5 matches with the outlet of extruder urceolus 1, head gland 3 compresses end plate 5 and links with extruder urceolus 1 spiral shell and connects, be fixed with screen pack 2 on the inwall of head gland 3, material is extruded by the extrusion cavities on the head gland 3 10 through filter screen 2 by the openend 6 of crossing filter tube 7.Wherein, filter tube bank 4 and be crossing the outer screen pack 8 that coated of filter tube 7 and constitute, have filtrate through hole 9 on the filter tube 7.
