Description
Technical field
The present invention relates to construction implement technical field, relate in particular to a kind of mixer.
Background technology
Mixer, is that a kind of blade-carrying axle rotates in cylinder or groove, and plurality of raw materials is uniformly mixed, and makes it to become the machine of a kind of mixture or suitable denseness.Mixer is mainly divided into these three kinds of forced mixers, single horizontal shaft blender, twin-shaft mixer.
In building, common mixer is cement concrete mixer, and its purposes is exactly the mixing cement concrete of mechanization, and its kind is more.
One, by operating type, be divided into two kinds of cycle operation formula and continuous operatings.
The feed of cycle operation formula, stirring, discharging three process were undertaken by the certain time interval cycle, by a part mixing.Because the various materials of mixing are all through weighing accurately, therefore mixing quality is good; Therefore in actual use, mostly adopt the operating type of this type.
The above-mentioned three process of continuous operating is to carry out continuously in a longer cylindrical shell.Although its productivity ratio is high compared with cycle operation formula, because match ratio, the mixing time of each material is difficult to control, therefore mixing quality is poor, actual use less.
Two, by agitating mode, be divided into two kinds of gravity type stirring, forced action type stirrings.
Self-dumping mixer is exactly that compound is placed in the mixing drum of a rotation, and along with the rotation of mixing drum, the blade in drum rises to certain height compound, then by deadweight, freely scatters.Carry out so again and again, until mix thoroughly.The general mixing plasticity of this mixer and semi plastic concrete.
Forced mixer is that mixing drum is motionless, and by the blade action of forced stirring of all putting on rotating shaft in drum.This mixer mixing quality is good, and production efficiency is high; But power consumption is large, and blade wear is fast.Generally be applicable to mixing dry concrete.
Common forced mixer in prior art, is to adopt the structure that drills through hole on shaft, this structural deterioration the original rigidity of steel, reduced shaft deflection, thereby the life-span of axle is shorter.
Publication number is CN 203170238U, the Chinese patent literature that open day is on 09 04th, 2013 discloses a kind of biaxial rneader, comprise motor, pneumatic clutch, decelerator, uncovered agitator tank, described motor is by pneumatic clutch connection reducer, it is characterized in that: described biaxial rneader also comprises two shafts and a protective cover, described two shafts are set in parallel in described agitator tank, on described shaft, be arranged with stirring blade, one end of described two shafts is all connected with the output shaft of decelerator, described protective cover is fixed on the top of described agitator tank, and the size of protective cover and described agitator tank is uncovered in the same size, described protective cover equal intervals arranges a plurality of reinforcements.
The disclosed biaxial rneader of this patent documentation, stirring blade is directly set on shaft, one end of shaft is directly connected with the output shaft of decelerator, connected mode adopts two cross shaft coupling heads to connect, wherein a cross shaft coupling head is assemblied on shaft, and another part cross shaft coupling head is assemblied on reductor slow-speed shaft, its span that stirs arbor is excessive, after the long-term use of equipment, mixer shaft deflection is excessive, stir the flexible distortion of arbor, thereby it is not high to cause stirring material amount of cure, brickmaking weak effect; Stirring blade blade is directly through at the structure stirring on arbor, can affect the rigidity of axle, shortens the service life of stirring arbor; Meanwhile, this project organization also can make stirring blade blade exchanging difficulty, increases the consumable accessory replacement cost of user in equipment is used.
