Detailed description of the invention
In order to explain technical scheme of the present invention further, be described in detail below by specific embodiment.
The blade connection structure of a kind of mixer helical axis of the present invention, as Figure 1-5, comprises spiral helical axis main body 1 and fixedly covers the abrasion-resistant blade 2 on the working face of helical axis main body 1.
Improvements are, abrasion-resistant blade 2 comprises and multiplely extends spirally along helical axis main body 1 the blade monomer 21 that direction arranges in turn, each blade monomer 21 all welds together with the both sides of the working face of helical axis main body 1, and weld together between adjacent blade monomer 21, in actual use, because abrasion-resistant blade 2 is made up of multiple blade monomer 21, deformation extent when abrasion-resistant blade 2 covers along helical axis main body 1 can be reduced, reduce the load of abrasion-resistant blade 2 and helical axis main body 1 fixed connection place, strengthen overall working strength, and arrangement covers blade monomer 21 one by one, technique is simple, easy to operate, and when situations such as local blade monomer 21 are damaged, dismounting can be carried out to partial blade monomer 21, repair and change, blade monomer 21 all welds with the both sides of the working face of helical axis main body 1, and namely weld 3 is on the non-working surface of working face both sides, the combination close and firm more of blade monomer 21 and helical axis main body 1, and be welded to form an integrated carrying wear-resistant surface between adjacent blade monomer 21, namely weld 4 is between two between blade monomer 21, form related fixed structure all linked with one another, when one blade monomer 21 ftractures with the weld 3 of helical axis main body 1, this blade monomer 21 can be fixed by the blade monomer 21 of the left and right sides, dropping situations can't occur, helical axis still can normally work, and service behaviour is stronger, the defects such as the bonding strengths such as entirety is secure rigid more, and the abrasion-resistant blade overcoming traditional mixer helical axis easily loosens, plug-hole, fracture, wearing and tearing come off are low, service behaviour is poor.
Preferably, blade monomer 21 is rectangle, and long edge the width of the working face of helical axis main body 1, this structure can guarantee that blade monomer 21 is less along the size in the hand of spiral of helical axis main body 1, and then reduce the deformation extent connected and in use procedure, and then be more convenient to carry out welding procedure, and reduce the load of weld 3 and weld 4, strengthen working strength.
Preferably, blade monomer 21 is in square.
In order to more adapt to the helical structure of helical axis main body 1, strengthen the matching of abrasion-resistant blade 2 and helical axis main body 1, preferably, blade monomer 21 is in fan-shaped, long arc limit is corresponding with the outer ledge of the working face of helical axis main body 1, and short arc limit is corresponding with the inside edge of the working face of helical axis main body 1.
Preferably, blade monomer 21 is the double layer composite board that wear resistant outer layer 211 is compounded to form with weldability internal layer 212, wear resistant outer layer 211 can ensure the scuff resistance of abrasion-resistant blade 2 entirety, and weldability internal layer 212 can ensure that blade monomer 21 and helical axis main body 1 implement welding procedure.
In order to specific implementation wear resistant outer layer 211 and weldability internal layer 212, preferably, wear resistant outer layer 211 is made up of carbide alloy, and the steel that weldability internal layer 212 is Q235 by yield strength are made.
The blade connection structure of mixer helical axis of the present invention, the material of wear resistant outer layer is preferably carbide alloy, the material of weldability internal layer is preferably Q235 steel, and when meeting the two performance requirement, the material of the two also can be chosen according to actual requirement; The version of blade monomer also can carry out adjusting and designing according to actual requirement; Shape, the size and quantity etc. of blade monomer all can be carried out adjusting and designing according to actual requirement; The structure of helical axis main body is roughly existing helical axis body format, but can be cooperation technical scheme of the present invention and do adaptive structural adjustment.
Product form of the present invention is not limited to this case diagram and embodiment, and anyone carries out suitable change or the modification of similar thinking to it, all should be considered as not departing from patent category of the present invention.
