The blade of slurry mixer
Technical field
A blade for slurry mixer, belongs to mud stirring apparatus field.
Background technology
Existing slurry mixer is vane type mostly, as application number: 91202977.3 mixer, on-stream while encountering stone, rock ballast, often occur the phenomenon that blade is blocked, because the blade of this class mixer is all rigid blade, the shaft also having is to be welded to connect with blade, so, suppress bad motor, Duan blade, not curved shaft or the accident of damaging tank body happen occasionally.And this class mixer is the angle of bad adjustment blade and the space between blade and inner tank wall also.
Summary of the invention
Object of the present invention, is the blade that will design a kind of slurry mixer, and this blade has flexibility, with this, eliminates the defect of above-mentioned rigid blade.The structure of the blade of this slurry mixer is connected to form by blade face, petiole and nut.(autobody sheet that a kind of), the isosceles trapezoid that the front shape on blade face is fillet, the thick middle on blade face are made with spring steel plate in the blade face of blade, periphery is thin and steel is tough sharp, good springiness, improves the shearing force of blade in stirring with this, thereby improves the operating efficiency of mixer.Major part one end on blade face, is provided with row's (several) silk hole along the central longitudinal axis on blade face, for being connected with petiole.
Petiole is one section of cylinder, and the diameter of petiole is greater than the interior thickness on blade face, at the middle part of petiole, longitudinally be provided with one section of draw-in groove, the width of draw-in groove equals the interior thickness on blade face, in the draw-in groove section of petiole, is provided with row's silk hole, and this hole is corresponding with the silk hole being located on blade face.The one end on blade face (having a hole) is embedded in draw-in groove, in silk hole, inserts screw or rivet fastening, one end of blade face and petiole is vertically connected and is integral.
The other end at petiole is provided with one section of screw thread, and petiole can penetrate in the hole of shaft (punching on shaft in advance), and petiole penetrates after the hole of shaft with fastening nuts, and the blade face after fastening is fixed on shaft.On petiole, pad can be put, by the pad quantity between plus-minus blade face and shaft, the space between top, blade face and inner tank wall can be adjusted.By the orientation on rotation blade face, the angle of inclination in the time of can adjusting blade face stirring.The blade of this slurry mixer, after running into stone and being blocked, can self produce elastic deformation, thereby after getting around stone, continues to stir the infringement of having avoided rigid blade to bring.In the time that blade need to being changed, unload the nut of petiole.

The specific embodiment
As shown in Figure 1, 2, the structure of the blade of slurry mixer is connected to form by blade face 1, petiole 2 and nut 3.The blade face 1 use spring steel plate of blade is made (autobody sheet that a kind of), the isosceles trapezoid that the front shape on blade face 1 is fillet, the thick middle on blade face 1, periphery is thin and steel is tough sharp, good springiness, improves the shearing force of blade in stirring with this, thereby improves the operating efficiency of mixer.Major part one end of 1 on blade face, along blade face, 1 central longitudinal axis is provided with row's (several) silk hole 8, for being connected with petiole 2.
Petiole 2 is one section of cylinder, and the diameter of petiole 2 is greater than the interior thickness on blade face 1, at the middle part of petiole 2, longitudinally be provided with one section of draw-in groove 7, the width of draw-in groove 7 equals the interior thickness on blade face 1, in the draw-in groove section of petiole 2, is provided with row's silk hole 8, and this hole 8 and the silk hole 8 being located on blade face 1 are corresponding.The one end on blade face 1 (having a hole) is embedded in draw-in groove 7, and interior insertion screw or rivet fastening in silk hole 8, be vertically connected one end of blade face 1 and petiole 2 and be integral.
The other end at petiole 2 is provided with one section of screw thread 3, and petiole 2 can penetrate in the hole of shaft 6, and petiole 2 penetrates after the hole of shaft 6 fastening with nut 4, and the blade face 1 after fastening is fixed on shaft 6.On petiole 2, pad 5 can be put, by the pad quantity between plus-minus blade face 1 and shaft 6, the space between 1 top, blade face and inner tank wall can be adjusted.By the orientation on rotation blade face 1, the angle of inclination in the time of can adjusting blade face 1 stirring.The blade 1 of this slurry mixer, after running into stone and being blocked, can self produce elastic deformation, thereby after getting around stone, continues to stir the infringement of having avoided rigid blade to bring.In the time that blade 1 need to being changed, unload the nut 4 of petiole 2.
