Description
Technical field
The utility model relates to a kind of fly cutter that is used for mixer, and this fly cutter is particularly useful for colter formula mixer, belongs to the mixer field that has gyratory agitation device in fixed container.
Background technology
Mixer is a plant equipment of utilizing mechanical force and gravity etc. that two or more material is evenly mixed.Mixer can fit in various materials uniform mixture, as cement, sand, rubble and water are mixed into concrete wet feed etc.Colter formula mixer is as mixer at present commonly used, the drying that is widely used in powders such as dry powder and mortar, plastics, rubber additive with mix.
Chinese patent literature CN201231142Y discloses a kind of colter formula mixer, comprise bleeder valve, reductor, cylindrical shell, colter, main shaft and charging aperture, mixer starts the back colter by the main shaft driven rotary, make material radially do circumferential turbulence along cylindrical shell, material is dished out along the normal direction of colter two sides, many group fly cuttves are installed on the main shaft of the output motor of cylinder body outer wall, when being dished out and make the described fly cutter of the too much group of material flow warp of circumferential turbulence, the strong rapidly throwing of the described fly cutter that is rotated is at a high speed loose, and makes material reach full and uniform mixing.Find in use which kind of structure fly cutter adopts the abundant mixing of material is had a significant impact.The prior art does not disclose the fly cutter structure, the applicant recognizes that from traditional fly cutter structure fly cutter be arranged in parallel at certain intervals along described electric machine main shaft the prior art, each fly cutter comprises along circumferential four the straight knife sheets (as shown in Figure 1) radially of described electric machine main shaft, the fly cutter of this kind traditional structure can play the diffusing effect of good throwing for bulky grain, heavy material, but in use find: this kind fly cutter structure is relatively poor for the mixed effect of the light material that contains bulk glass chopped strand, can not realize the full and uniform mixing of material.
The applicant finds through further investigation and test: for the mixing of the light material that contains bulk glass chopped strand, should consider that fly cutter is shed in rotation at a high speed can not twine too much fiber in the material process and influence and shed efficient, also to consider bulk glass chopped strand fully can be opened to realize the abundant mixing of material, the fly cutter of above-mentioned prior art is when applying to the mixing of bulk glass chopped strand light material, it utilizes the mode of by the high speed revolving force bulk fiber being opened in the tip insertion bulk glass chopped strand of straight knife sheet to satisfy the requirement that fly cutter can not twine too much fiber, but because each straight knife sheet has only a tip in the fly cutter direction of rotation, this kind set-up mode has determined the fly cutter of this kind structure well bulk glass chopped strand not to be opened, but, if simple increase most advanced and sophisticated quantity and then can not solve bulk glass chopped strand and in shedding process, twine too much problem, thus the high efficiency requirement can't satisfy mixing of materials the time.
In sum, fly cutter structure of the prior art can not solve the problem of the high efficiency requirement of stirring for material simultaneously and avoid material to twine the problem of fly cutter in whipping process when being applied to the mixing of bulk glass chopped strand light material.
The utility model content
For this reason, technical problem to be solved in the utility model is to provide a kind of fly cutter that can solve the problem of the high efficiency requirement of stirring for material simultaneously and avoid the problem of material winding fly cutter in whipping process.
For solving the problems of the technologies described above, the utility model provides a kind of fly cutter that is used for mixer, be suitable for being installed in the mixer cylindrical shell and be suitable under the driving of fly cutter drive unit the driving rotating shaft with described fly cutter drive unit and together rotate, described fly cutter comprises a plurality of blades of circumferentially arranging radially that are suitable for along described driving rotating shaft; Side towards direction of rotation of described blade is stairstepping, and the height that is the described blade of stairstepping one side is extremely successively decreased away from the top of described driving rotating shaft step by step by the root near described driving rotating shaft.
Forming from high to three low steps of described blade towards a side of direction of rotation root to top away from described driving rotating shaft near described driving rotating shaft (3).
Described blade is four, and evenly is provided with along the direction of rotation of described blade.
Angle between the two adjacent described fly cuttves is 90 °.
The angle of the axis of described blade and described driving rotating shaft is 60 °-90 °.
The angle of the axis of described blade and described driving rotating shaft is 90 °.
Described fly cutter is the antifriction alloy foundry goods.
Technique scheme of the present utility model has the following advantages compared to existing technology:
1, in the utility model, side towards direction of rotation of described blade is stairstepping, the height that is the described blade of stairstepping one side is extremely successively decreased away from the top of described driving rotating shaft step by step by the root near described driving rotating shaft, this species stage shape structure provides a plurality of tips to be used to insert bulk glass chopped strand and has opened it, improved the mixing efficiency of mixer, and the height of described blade that is stairstepping one side is by having prevented that near the root of described driving rotating shaft to the set-up mode that successively decreases step by step away from the top of described driving rotating shaft fly cutter from can not twine too much bulk glass chopped strand in the high speed rotary course for the light material that contains bulk glass chopped strand
2、。In the utility model, angle between the axis of described blade and described driving rotating shaft is 90 °, be directed to chopped strand (the about 5-12mm of length of specific standard, fibre diameter 7-13 μ m), in mixed process, because fiber is relative with the frictional force between powder less, if angle too small, fiber because of very easily uniting, causes the dispersion effect variation in mixed process.The applicant attempts by experiment repeatedly, draws when angle is 90 °, and the fly cutter shearing force provides enough dispersion space, make fiber fully rub and mix with powder, the while mixed material under fly cutter shear stress and stirring blade effect, dispersion effect the best.
3, in the utility model, described fly cutter is the antifriction alloy foundry goods, and high abrasion resistance properties is arranged, and can prolong described fly cutter effectively is the antifriction alloy foundry goods.
