Abstract
The utility model discloses a conical twin-screw extruder barrel, which comprises a feeding section, a melting section and an extrusion section. A wear-resistant layer is lined on the inner wall of a barrel inner cavity fitted with twin screws in the melting section and/or the extrusion section in the manner of shaking off; the wear-resistant layer completely covers the inner wall of the barrel inner cavity; and the shape of the surface of the inner wall of the wear-resistant layer is fitted with the twin screws. The conical twin-screw extruder barrel disclosed by the utility model has the advantages that the wear-resistant layer is lined on the inner wall the barrel inner cavity fitted with twin screws in the melting section and/or the extrusion section in the manner of shaking off, and as the wear-resistant layer completely covers the inner wall of the barrel inner cavity and the shape of the surface of the inner wall of the wear-resistant layer is fitted with the twin screws, the structure is simple, and the inner wall of the barrel inner cavity cannot be easily abraded. When the wear-resistant layer is abraded, only the whole wear-resistant layer needs to be replaced. The wear-resistant layer not only is convenient and rapid to replace, but also is not high in cost.
Description
Technical field
The utility model relates to extruder and makes technical field, especially relates to a kind of cone double machine barrel.
Background technology
Existing a kind of application number is that the CN02254687.1 name is called the Chinese utility model patent of " the conical dual-screw plastic extruder barrel that the cylindrical shell abrasion resistance is good ", the good conical dual-screw plastic extruder barrel of a kind of cylindrical shell abrasion resistance is disclosed, it is comprised of cylindrical shell and screw rod, the endoporus of cylindrical shell is two crossing bellmouths, be respectively equipped with conical screw in two bellmouths, be inlaid with carbide chip on the inner hole wall of cylindrical shell.Cylinder bore of the present utility model the inside tungsten carbide button blade, because the hardness of carbide alloy is far longer than the case hardness after the oxidation, the thickness that adds its blade surpasses bimetallic coating thickness, so under specific pressure, it is very small that the wearing and tearing of its cylindrical shell become, so that be largely increased the service life of cone double shell.But, this alloy blade is embedded on the inner hole wall of cylindrical shell dispersedly, the phenomenon of wearing and tearing appears in inner hole wall easily that be not coated with alloy blade, thereby so that the machine tube inner wall wearing and tearing are uneven, and after wearing and tearing appear in alloy blade, need alloy blade is changed one by one, both lost time, increase again cost, therefore, the structure of this machine barrel needs further improvement.
Also having a kind of application number is that the CN200420044207.0 name is called the Chinese utility model patent of " the conical dual-screw plastic extruder barrel that the cylindrical shell abrasion resistance is good ", a kind of conical double screw rod extruder tubular body is disclosed, replaceable lining by urceolus and Qi Nei consists of, lining is to have certain wall thickness, and endoporus is the taper column that two crossing circular holes, cross sections are the splayed ring.Lining can be according to the segmentation of urceolus and formed by segmentation docking or the overlap joint of correspondence; Lining also also can be divided into two semi-rings from the cross section or a semi-ring adds two 1/4th rings, four 1/4th ring compositions.Since can be easily after this novel conical double screw rod extruder tubular body liner wear resleeve more, thereby saving of work and time reduces cost.But the lining mar proof of this machine barrel is good not, and it is frequent to cause lining to be changed, and increases cost, so the structure of this machine barrel also needs further improvement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure for above-mentioned prior art present situation, and is wear-resistant, changes convenient and the low cone double machine barrel of cost.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this cone double machine barrel, include feed zone, fusing section, extruding zone, it is characterized in that: in described fusing section and/or extruding zone with the suitable machine barrel of twin-screw on the cavity wall dismountable type lining wearing layer is arranged, this wearing layer all covers cavity wall in the machine barrel, and inner wall surface shape and the twin-screw of this wearing layer are suitable.
As improvement, described wearing layer forms by two, and every is " C " shape, respectively symmetrically lining in machine barrel on the cavity wall.
Improve, the structure of described dismountable type is that described wearing layer is axially tapered again, and the outer wall shape of described wearing layer is corresponding with the shape of machine tube inner wall, and by the conical surface machine tube inner wall and wearing layer outer wall is close to mutually to tighten together.
Improve, dismountable type is provided with wearing layer on the machine tube inner wall of described feed zone again.
Improve, described extruding zone is that dismountable type is connected with the machine barrel of fusing section again.
Improve, described dismountable type is connected to extruding zone and is connected by bolt with the machine barrel of fusing section again.
Improve, described fusing section is that dismountable type is connected with the machine barrel of feed zone again.
Improve, described dismountable type is connected to the fusing section and is connected by bolt with the machine barrel of feed zone again.
Compared with prior art, the utility model has the advantage of in fusing section and/or extruding zone with the suitable machine barrel of twin-screw on the cavity wall dismountable type lining wearing layer is arranged, because this wearing layer all covers inwall, and inner wall surface shape and the twin-screw of this wearing layer are suitable, simple in structure, and make the difficult wearing and tearing of cavity wall in the machine barrel, when wearing and tearing appear in wearing layer, only need to change whole wearing layer and get final product, both convenient, quick again, and cost is not high.Also have, extruding zone is that dismountable type is connected with the machine barrel of fusing section, melts section machine barrel with feed zone also for dismountable type is connected, and this structure is convenient to dismounting and the cleaning of machine tube inner wall, and makes the easier for installation, quick of wearing layer.
