A kind of shimmy formula blender
Technical field
The utility model relates to a kind of mixture Mixing Machines, more particularly to one kind is suitable for cement stabilized soil, pitch mixes
Close the shimmy formula blender of material, cement concrete and cement mortar.
Background technique
The function of blender is prepared various materials in proportion to be mixed by stirring into uniform, and meets quality and wants
The mixture asked.
Currently used blender is generally divided into self-falling mixer and forced mixer.Self-falling mixer is to utilize
Its internal flow distribution plate carries out being repeatedly lifted up segmentation to material in cylinder when a mixing bowl rotates, gravity falls, to keep material continuous
Dispersion is distributed and achievees the purpose that uniform mix;
Forced mixer then shears material using the agitating shaft of rotation and its blade, squeezed, stirs and turns over it
Mix is forced in rolling, convection current etc., so that material, which is in relatively violent relative motion, obtains uniform mix.
The stirring intensity of forced mixer is much larger than self-falling mixer, can produce relative mass and preferably mix
Material.Therefore, forced mixer has been that building trade and road construction industry produce cement concrete, cement stabilized soil, drip
The main type of green mixture.
Although forced action type stirring can produce relatively good mixture, microcosmic above to still have non-uniform phenomenon.
By taking cement class mixture as an example, such as cement stabilized soil, cement concrete and cement mortar, it is microcosmic on still have 10% -30%
Cement granules there are adhesive aggregation conglomerations, i.e., the material being stirred by forced mixer can still find more under the microscope
" cement granule ".Again by taking asphalt as an example, due to bituminous binder sticky nature itself, in addition in asphalt
Aggregate is made of coarse aggregate, fine aggregate, powder, and attached, and fine aggregate and powder are relatively easily wrapped up in coarse aggregate surface by pitch
Surface is then difficult to be wrapped up in completely attached under general stirring action, can not form high performance cementing material, so that between coarse aggregate
Cementation reduces.
In order to solve the above technical problems, occurring following two Vibratory Mixing mode in recent years, it is mainly characterized in that:
1, on the basis of forced mixer, in the both ends or one end of agitating shaft (hollow or solid), using eccentric shaft
Installation stirs the form of bearing to support agitating shaft in bearing sleeve, and eccentric shaft bearing sleeve makes to stir by motor driven high speed rotation
Axis generates vibration, to realize the Vibratory Mixing of mixture.But in place of the blender Shortcomings of this structure:Agitating shaft
Either hollow shaft or real axis, after installing mixing arm and stirring blade, construction weight is all relatively large, to be its production
Raw vibration, needs biggish driving power.In addition the driving high-speed rotating vibration bearing seat of eccentric shaft bearing sleeve and other components
It rigidly fixes together on the rack, frame vibration is very big, influences working environment.Vibration can also make the fastener pine of other components
It is dynamic, or even the components earlier period damage having.This device, structure is complex, and manufacture difficulty is larger, especially hollow shaft sleeve,
Product cost is higher.
2, it on the basis of forced mixer, by the stirring bearing block of agitating shaft both ends or one end, is mounted on one and floats
On dynamic frame, floating frame is connected using damper with rack, the upper plane of floating frame or side install vibrating motor or
Other forms vibration excitor, vibrates floating frame, to drive stirring shaft vibration, realizes Vibratory Mixing.But this structure
It has the following disadvantages:It is all knot due to the mixing arm and stirring blade and floating frame installed on agitating shaft and agitating shaft
The very big component of structure weight will make so big construction weight generate vibration, it is necessary to which applying very big oscillation power can make
It stirs shaft member and floating frame vibration is got up, realize Vibratory Mixing.
