Abstract
The utility model relates to the technical field of extruders, in particular relates to an extruder barrel; the extruder barrel is provided with an alloy layer sprayed on the inner surface of the barrel, thus being good in wear resistance and erosion resistance; and according to the extruder barrel, as the homogenizing section of the barrel is easy to wear off, a lining is arranged on the alloy layer corresponding to the homogenizing section, so that the wear resistance and the erosion resistance of the extruder barrel are further improved.
Description
Technical field
The utility model relates to the extruder technology field, is specifically related to a kind of extruder barrel.
Background technology
The technical process such as double screw extruder is widely used in mixing in the processing such as plastics, rubber, synthetic fibers, coating, paper pulp and pharmacy, food, extrudes, moulding and reaction.Because the inwall of cylindrical shell will bear very large extrusion friction power during work, so require to have good abrasive resistance; Simultaneously in some occasion, extruder both need possess the ability of long-term high temperature resistant and temperature difference sudden change, tolerated again certain corrosion.
Therefore, producer adopts cylinder inner surface is carried out nitrogen treatment when making such extruder, although but the top layer of surfaces nitrided processing gained is very hard, but the same easily wearing and tearing of very thin thickness particularly are easy to wearing and tearing corresponding to homogenizing zone place cylindrical shell, and then make the cylinder inner surface corrosion and inhomogeneous.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of extruder barrel of wear resistant corrosion resistant is provided.
The utility model is realized by following technology: a kind of extruder barrel, comprise cylindrical shell, and the inner surface of described cylindrical shell is coated with alloy-layer, is provided with lining corresponding to the alloy-layer of homogenizing zone.
The thickness of described alloy-layer is 2-5mm.
Described lining is the carburizing alloy steel lining.
The beneficial effects of the utility model are: the utility model is coated with alloy-layer at the inner surface of cylindrical shell, not only wear-resisting but also good corrosion resistance arranged, because the cylindrical shell corresponding to the homogenizing zone place is easy to wearing and tearing, the utility model is provided with lining at the alloy-layer corresponding to homogenizing zone again, has further improved wearability of the present utility model and corrosion resistance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Reference numeral
1---cylindrical shell
2---alloy-layer
3---lining.
The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing the utility model is further described, the content that embodiment is mentioned not is to restriction of the present utility model.
See Fig. 1, a kind of extruder barrel comprises cylindrical shell 1, and the inner surface of cylindrical shell 1 is coated with alloy-layer 2, is provided with lining 3 corresponding to the alloy-layer 2 of homogenizing zone.The utility model is coated with alloy-layer 2 at the inner surface of cylindrical shell 1, not only wear-resisting but also good corrosion resistance arranged, because homogenizing zone place cylindrical shell 1 is easy to wearing and tearing, the utility model is provided with lining 3 at the alloy-layer 2 corresponding to homogenizing zone again, has further improved wearability of the present utility model and corrosion resistance.
The thickness of alloy-layer 2 is 2-5mm, not only saves cost but also can guarantee wearability of the present utility model and corrosion resistance.
Lining 3 is the carburizing alloy steel lining, and the wearability of carburizing alloy steel lining and corrosion resistance are good.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
