Description

Mpp power pipe extruded stock defecator

Technical field

This utility model relates to a kind of mpp power pipe extruded stock defecator, relates generally to plastic extruding forming processing neck Territory.

Background technology

MPP power pipe uses modified polypropene to be main raw material(s), is need not to dredge in a large number, cut the earth and destroy road surface, The construction works such as road, railway, building, riverbed inferior Special zone roughing-in, cable.With traditional " grooving pipe laying method " Comparing, no-dig technique power pipe engineering more adapts to current environmental requirement, remove because of traditional construction caused stir up a cloud of dust, traffic The factors that disturb residents such as obstruction, this technology can also be at some regional pipeline installations that cannot implement to excavate operation, such as paleovolcanic structure District, business district, crops and farmland protection area, highway, river etc..

Mpp power pipe, by extruder for shaping, can add various filler in production process, these fillers are in extrusion Having the more part being difficult to and plastifying before, extruding in power pipe if allowing this part mix, can be to the quality of power pipe Produce various impact, such as stain, flake etc..Therefore screen plate is set between extruder and mould, when the impurity on screen plate After blocking up completely, need screen plate is carried out remove impurity.In the extrusion processing of Application No. 200910042353.7 title one polyvinyl chloride resin In the patent of device for filtering impurities, disclose a kind of defecator alternately worked, two independent melting charge roads be set, Two melting charge roads alternately work, and can reach to remove filter element although using this scheme just can not shut down Miscellaneous, but when melting charge road is in period alternately, raw material cannot pass through pipeline, now needs for stopping producing, because of This cannot solve to produce the extruding pipe material successional problem of work thoroughly.

Utility model content

For above the deficiencies in the prior art, the utility model proposes a kind of mpp power pipe ensureing continuous production and squeeze Discharge filtering device.

For reaching above-mentioned purpose, the technical solution of the utility model is: include extruder, mould and screen plate, whole mistake Being laid with some filtration through holes on filter plate, a screen plate part is arranged between mould and extruder cross section, and screen plate connects There is driving means that the zones of different of screen plate is contacted with extruder cross section.

Know-why of the present utility model is as follows: carrying out mpp power pipe production and processing when, by raw material from extrusion Machine is extruded, stays the side of screen plate through filter plate impurity, enter mould through the raw material filtered.The electricity of extruder Pressure and electric current be when significantly increase, and the impurity of screen plate is described, and it is enough, needs remove impurity.Start driving means, will Screen plate moves, and makes the region not having impurity move to mould and extruder interface zone, moves to mould when not having extrinsic region Tool and extruder section, have impurity part just to depart from from mould and extruder section, the most just can carry out this region Remove impurity.

The beneficial effects of the utility model are as follows: owing to whole screen plate is designed with filtering holes, therefore having impurity part The when of the filtering holes break away from moulds of screen plate and extruder cross section, the filtering holes of impurity Partial filtration plate is not had to simultaneously enter Mould and extruder section, the passage not havinging extruder and mould changing filter plate plate filtering holes when is complete Full isolation, raw material has new filtering holes and enters at mould.The most whole production process will not stop, and can fully ensure that production Seriality and efficiency.

Further, screen plate is rectangular slab, and screen plate is driven up and down by cylinder, producing when, by cylinder band Dynamic screen plate moves up and down, and then changes rectangular slab and mould and extruder cross section and contact area.

Further, screen plate is circular slab, and the axle center of this circular slab is driven by motor, is turned by driven by motor circular slab Dynamic, it is circular slab directional rotating, therefore continuous being partially between mould and extruder either with or without impurity.

Detailed description of the invention

Below in conjunction with accompanying drawing, the technical scheme in this utility model is clearly and completely described, it is clear that retouched The embodiment stated is only preferred embodiment of the present utility model rather than whole embodiments.Based in this utility model Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all Belong to the scope of this utility model protection.

Embodiment

Embodiment 1

As shown in Figure 1: the present embodiment includes top cap plate 4, extruder 5 and mould 6, top cap plate 4 is arranged on crowded Going out between machine 5 and mould 6, extruder 5 and mould 6 joint are provided with vertical sliding into, top cap plate 4 be arranged in slideway with It is slidably matched.

As in figure 2 it is shown, be vertically provided with cylinder 1, cylinder outfan by support 7 above extruder 5 and mould 6 joint 2 are connected with the top of top cap plate 4, and by the drive of cylinder 1, rectangular slab moves up and down, and the impurity on rectangular slab is too much When, start cylinder 1 and top cap plate 4 is driven downwards or downwards, do not have the top cap plate 4 of impurity part to be positioned at crowded Go out between machine 5 and mould 6, have the top cap plate 4 of impurity part skid off outside and then top cap plate 4 is cleared up.

On whole top cap plate 4, local is provided with some filtering holes 3.

Embodiment 2

Being provided with circular filter plate 8 at extruder 5 and mould 6 joint, the center of circle of circular filter plate 8 is positioned at extruder 5 sections Outside the circle of face, by driven by motor, motor output end 9 is connected with the center of circle of circular filter plate 8.

Principle with embodiment 1, when circular filter plate 8 extruder 5 go out impurity too much when, impurity part will be had to rotate Go out, do not have impurity part to rotate and enter to replace.

On whole circular filter plate 8, local is provided with some filtering holes 3.
