Abstract
The utility model provides a conical double screw rod extruder cylinder body, which is composed of an outer cylinder (1), and an exchangeable lining (2) in the outer cylinder. The lining is a tapered column body with definite wall thickness, two intersecting round holes as inner holes, and a cross section of a splay ring shape. The lining can be formed by the corresponding segments butted or overlapped according to the segments of the outer cylinder. The lining (2) can also be formed by two half rings or one half ring with two one quarter rings or four one quarter rings on the cross section. Because the lining of the conical double screw rod extruder cylinder body can be exchanged conveniently after worn out, the utility model has the advantages of saving labour, saving time and reducing cost.
Description
Technical field
The utility model relates to a kind of conical double screw extruder machine barrel cylindrical shell, and the conical double screw extruder machine barrel cylindrical shell of slip bushing is arranged in especially a kind of.
Background technology
The conical double screw extruder machine barrel mainly is made up of cylindrical shell and twin-screw, and the cross section of cylindrical shell endoporus is two crossing circular holes, is loaded on conical double-screw it in from the linear change that diminishes greatly with cooperation along axis.Because the inwall of cylindrical shell will bear very big extruding friction during work, so require to have good abrasive resistance, existing for this reason cylinder inner surface, the surfaces nitrided processing of the employing that has, or at surface spraying alloy to improve case hardness, the way that the employing that also has is inlayed many pieces of carbide chips in cylinder inner surface serious wear part is as Chinese patent communique disclosed Chinese utility model patent on October 1st, 2003 " the conical double screw extruder machine barrel that the cylindrical shell abrasion resistance is good) " (02229223.3).Though top layer that can surfaces nitrided processing gained is very hard but also very thin, also just be easy to the top layer of wearing and tearing equally, and in case wearing and tearing be above standard and just can only process processing again, time-consuming take a lot of work very inconvenient, then cost is too high for the spraying alloy, can produce the wearing and tearing inequality again at drum surface tungsten carbide button blade.
The utility model content
The purpose of this utility model is to provide a kind of and had not only had higher scuff resistance inwall and restore the wearing and tearing back but also conical double screw extruder machine barrel cylindrical shell very simply and easily.
For achieving the above object, conical double screw extruder machine barrel cylindrical shell of the present utility model is made of the replaceable lining of urceolus and Qi Nei.
Described lining be have certain wall thickness, endoporus is the taper column that two crossing circular holes, cross sections are the splayed ring.
Described lining also can be divided into two semi-rings from the cross section or semi-ring adds two 1/4th rings, four 1/4th rings are formed.
Described lining sectional butt joint or overlap joint.
The beneficial effects of the utility model are: because this novel conical double screw extruder machine barrel cylindrical shell is made of urceolus and replaceable lining, just can be easily after liner wear more resleeve get final product, saving of work and time reduces cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the tube structure cross-sectional schematic of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
Fig. 4 is the cross-sectional schematic of urceolus segmental structure.
Fig. 5 is that schematic diagram is looked on the left side of Fig. 4.
Fig. 6 is the cross-sectional schematic of segmentation bush structure.
Fig. 7 is that schematic diagram is looked on the left side of Fig. 6.
Among the figure: 1 urceolus, 2 linings.
The specific embodiment
From Fig. 1 to Fig. 5, can see, conical double screw extruder machine barrel cylindrical shell of the present utility model, by urceolus 1 with fix lining 2 in it, replaceable and constitute, urceolus 1 by detachable segmentation to being connected into integral body, lining 2 also correspondingly segmentation butt joint form, it is shaped as has certain wall thickness, and endoporus is the taper column that two crossing circular holes, cross sections are the splayed ring.Ring adds two 1/4th rings, four 1/4th rings are formed.The lining endoporus should cooperate the conical double-screw that is loaded in it, and lining is made by the Chromador of high rigidity, can process spare part earlier, ejects the wearing and tearing lining when urceolus being taken apart after with liner wear, changes to new standby lining again and get final product.
Whether lining can determine segmentation according to the length segmentation situation of urceolus, and the segmentation lining also can adopt overlapping mode to fuse, and appearance is other form such as frustum, cylinder etc. also, and these all fall into this novel protection domain.
Claims (4)
1, a kind of conical double screw extruder machine barrel cylindrical shell is characterized in that: described cylindrical shell is made of urceolus (1) and the replaceable lining (2) in it.
2, conical double screw extruder machine barrel cylindrical shell according to claim 1, it is characterized in that: for to have certain wall thickness, endoporus is the taper column that two crossing circular holes, cross sections are the splayed ring to described lining (2).
3, conical double screw extruder machine barrel cylindrical shell according to claim 1 is characterized in that: described lining (2) is docked by the segmentation of correspondence according to the segmentation of urceolus (1) or overlap joint forms.
4, conical double screw extruder machine barrel cylindrical shell according to claim 1 is characterized in that: described lining (2) also can be divided into two semi-rings from the cross section or semi-ring adds two 1/4th rings, four 1/4th rings are formed.
