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: the mixer of 91202977.3, on-stream when encountering stone, rock ballast, often occur that blade is by the phenomenon of card, because the blade of this kind of mixer is all rigid blade, the shaft also had is welded to connect with blade, so, suppress bad motor, Duan blade, not curved shaft or the accident damaging tank body happen occasionally.And this kind of mixer also bad angle of adjustment blade and the space between blade and inner tank wall.
Summary of the invention
Object of the present invention, be the blade that will design a kind of slurry mixer, this blade has flexibility, eliminates the defect of above-mentioned rigid blade with this.The structure of the blade of this slurry mixer is connected to form by blade face, petiole and nut.The blade face spring steel plate of blade is made (that of autobody sheet is a kind of), and the front shape on blade face is the thick middle on the isosceles trapezoid of fillet, blade face, periphery is thin and steel is tough sharp, good springiness, improves the shearing force of blade in stirring with this, thus improves the operating efficiency of mixer.In the major part one end on blade face, the central longitudinal axis along blade face is provided with row's (several) silk hole, is connected for 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, and be provided with row's silk hole in the draw-in groove section of petiole, this hole is corresponding with the silk hole be located on blade face.The one end (having a hole) on blade face is embedded in draw-in groove, in silk hole, inserts screw or rivet and fastening, one end of blade face and petiole is vertically connected integral.
Be provided with one section of screw thread at the other end of petiole, petiole can penetrate in the hole of shaft and (punch on shaft in advance), and petiole uses fastening nuts after penetrating the hole of shaft, and the blade face after fastening is fixed on shaft.Petiole can put pad, 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 rotating the orientation on blade face, angle of inclination when blade face is stirred can be adjusted.The blade of this slurry mixer run into stone by card after, self can produce elastic deformation, thus continue after getting around stone to stir, avoid the infringement that rigid blade brings.When needing to change blade, unload the nut of petiole.

Detailed description of the invention
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 of blade is made (that of autobody sheet is a kind of) with spring steel plate, and the front shape on blade face 1 is the thick middle on the isosceles trapezoid of fillet, blade face 1, periphery is thin and steel is tough sharp, good springiness, improves the shearing force of blade in stirring with this, thus improves the operating efficiency of mixer.In the major part one end on blade face 1, the central longitudinal axis along blade face 1 is provided with row's (several) silk hole 8, is connected for 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, is provided with row's silk hole 8 in the draw-in groove section of petiole 2, and this hole 8 is corresponding with the silk hole 8 be located on blade face 1.The one end (having a hole) on blade face 1 is embedded in draw-in groove 7, in silk hole 8, inserts screw or rivet and fastening, one end of blade face 1 and petiole 2 is vertically connected integral.
Be provided with one section of screw thread 3 at the other end of petiole 2, petiole 2 can penetrate in the hole of shaft 6, and petiole 2 is fastening with nut 4 after penetrating the hole of shaft 6, and the blade face 1 after fastening is fixed on shaft 6.Petiole 2 can put pad 5, by the pad quantity between plus-minus blade face 1 and shaft 6, the space between top, blade face 1 and inner tank wall can be adjusted.By rotating the orientation on blade face 1, angle of inclination when blade face 1 is stirred can be adjusted.The blade 1 of this slurry mixer run into stone by card after, self can produce elastic deformation, thus continue after getting around stone to stir, avoid the infringement that rigid blade brings.When needing to change blade 1, unload the nut 4 of petiole 2.
