Abstract
The utility model discloses an abrasion-proof helical blade of a screw conveyor, which comprises helical blades. A manganiferous welded metal material layer is uniformly laid in peripheral areas at the top of the helical blades of the screw conveyor. In the technical scheme, welding material adopts alloy steel welding rods, and the manganiferous welded metal material layer is uniformly laid in the peripheral areas at the top of the helical blades of the screw conveyor in a build-up welding manner, thereby improving the abrasiveness and the corrosion resistance of the helical blades, reducing the cost, and prolonging the service life of the complete machine.
Description
(1) technical field:
The utility model mechanical transport equipment is specifically related to the helicallobe of conveyor screw.
(2) background technology:
Conveyor screw is a kind of load transfer device that is industry widespread uses such as chemical industry, building materials, grain, is mainly used in conveying powdered, graininess and piece material.The ubiquitous problem of present conveyor screw is: the position that blade contacts with material, wearing and tearing, the corrosion of special blade periphery are serious.The material of the general usefulness of blade of common conveyor screw is structural carbon steel Q235, but structural carbon steel resistance to abrasion, corrosion-resistant, used a period of time after, helicallobe is fragile, has reduced the service life of complete machine.
(3) utility model content:
The purpose of this utility model is to provide a kind of abrasion resistant spiral blade of spiral conveyer, and cost of manufacture is low, simple and reliable, and the resistance to abrasion and the resistance to corrosion of helicallobe obviously strengthen, and have prolonged the service life of complete machine.
For achieving the above object, the technical scheme that a kind of abrasion resistant spiral blade of spiral conveyer of the utility model adopts comprises helicallobe, it is characterized in that: the top perimeter zone at the helicallobe of conveyor screw evenly is covered with the welded metal material layer that one deck contains manganese.
In technique scheme, owing to evenly be covered with the welded metal material layer that one deck contains manganese in top perimeter zone at the helicallobe of conveyor screw, this metal material layer resistance to abrasion and resistance to corrosion are good, can effectively strengthen the in-use performance of helicallobe, reduce cost, prolonged the service life of complete machine.
(4) description of drawings:
Fig. 1 is the mounting structure scheme drawing of a kind of abrasion resistant spiral blade of spiral conveyer of the utility model;
Fig. 2 is the structural representation of a kind of abrasion resistant spiral blade of spiral conveyer of the utility model.
(5) specific embodiment:
Following structure accompanying drawing is described in further detail a kind of abrasion resistant spiral blade of spiral conveyer of the utility model.
In Fig. 1, Fig. 2, the parent material of the helicallobe 1 of present embodiment remains and adopts structural carbon steel Q235, manufacture craft also is polylith annular arrangement steel plate to be drawn moulding link together, be welded on the conveying axis of control, use the alloy steel welding rod then, as: the D212 welding rod, the mode of employing built-up welding evenly is covered with the welded metal material layer 2 that one deck contains manganese in circumferential outer edge zone, helicallobe 1 top.Welding region as shown in Figure 2, the welding scope be helicallobe 1 with the positive friction face that contacts of material, the outer perimeter of helicallobe 1, helicallobe 1 and the reverse side material contact surface are apart from outer rim 10mm zone, throat depth is generally 3mm and gets final product.In order to obtain certain throat depth, adopt the layering welding.Mother metal will be incubated more than 300 ℃ in the welding process, prevents that the crack of weld in the welding process from producing.Through after such PROCESS FOR TREATMENT, just obtained relatively evenly and fine and close weld structure, helicallobe 1 resistance to abrasion and resistance to corrosion obviously improve, reduced cost, prolonged the service life of complete machine.
Claims (2)
1, a kind of abrasion resistant spiral blade of spiral conveyer comprises helicallobe (1), it is characterized in that: the top perimeter zone at the helicallobe (1) of conveyor screw evenly is covered with the welded metal material layer (2) that one deck contains manganese.
2, a kind of abrasion resistant spiral blade of spiral conveyer according to claim 1, it is characterized in that: the thickness of described welded metal material layer (2) is 3mm.
