Description
Technical field
The utility model belongs to forced stirring equipment field, more particularly to a kind of vertical vibrating with spiral vibrator
Blender.
Background technology
Cement concrete occupies extremely important status in modern construction, is widely used in highway communication, bridge
Tunnel, building construction etc..It is needed for this purpose, the performance of cement concrete must satisfy performance more and more high in current engineering construction
It asks.Numerous studies show that the interface between inside concrete aggregate and Behavior of Hardened Cement Paste is a ring weaker in concrete, pass through reinforcing
Whipping process or optimization stirring technique are come to improve interface binding intensity be one of important channel for improving concrete strength.Mesh
Before, the use of extensive blender is forced mixer in engineer application both domestic and external, operation principle is to pass through agitating device
Rotation, make raw material move in circles in mixing drum flowing so as to be uniformly mixed it, produce concrete.Forced action type stirs
Machine is compared with other types of blender, and production efficiency is high, and mixing quality is good, applied widely.
Although there are many advantages of forced mixer, there is also the solutions of some problems demands in practical applications.It is first
First, the stirring of forced mixer is macroscopically easily reaching uniform, but there are still sub-fraction cement on a microscopic scale
Clustered particles, this clustered particles reduce the contact area between cement and water, prevent hydration reaction between the two from filling
Divide and carry out, the performance of cement waste and mixture is caused not give full play to.Secondly, forced mixer leans in whipping process
The mixture flowing velocity in nearly agitating shaft region is small, influences the immixture between material, forms the inefficient area of stirring.Blender
After a long-term service, mixture can be attached to around agitating shaft, easily cause seizing phenomenon, tieed up to the cleaning of blender
Protecting band carrys out difficult, the reduction blender service life.
Exactly because there is deficiency, oscillating mixers to come into being for forced mixer.Oscillating mixer is to force
Vibrator is provided on the basis of formula blender, the high-frequency vibration and agitating device generated by vibrator jointly carries out material
Stirring action, to improve mixing quality and efficiency.The vibrator of existing oscillating mixer generates vibration, shaft end using eccentric center principle
Sealing effect it is bad, shaft strength is not in good state, and material is easily infiltrated between axis and bearing, under high speed rotation state easily
Fever exacerbates the abrasion of bearing, reduces bearing life；Meanwhile real work situation stress is complicated, vibrator at work by
Power is not easy to balance, and vibrational energy cannot all act on manipulating object and easily generate noise pollution so that construction condition
Badly, it does not meet the current environmentally protective requirement in China or even construction personnel's health can be influenced.

Compared with prior art, the utility model has following technique effect：
The utility model is provided with the spiral vibrator with N number of raised polygon, and during work, spiral vibrator often rotates one
Week, N number of protrusion collide with material, and material can be by the axial force and radial direction masterpiece generated from raised spiral at this time
With in chatter state.Material is stirred under high-frequency vibration state, the internal friction and cohesive strength between particle reduce,
Under the stirring action of agitating device, it is uniform that material can reach both macro and micro simultaneously.In addition, the vibration of vibrator promotes agglomerate
Dispersion becomes smaller cement little particle rapidly, increases the contact area with water, accelerates hydration reaction, further enhance aggregate and water
Interface binding intensity between mudstone.As it can be seen that the collective effect of vibration and stirring improves mixing quality and efficiency.With eccentric vibrating
Principle is different, and spiral vibrator generates vibration by protrusion, and vibrator barycenter overlaps always with rotation center during work, vibrational energy
Amount is only transmitted to material without being transmitted to rack, overcomes the deficiency of conventional vibration blender.
The utility model is related to spiral vibrator compared with existing blender vibrator, can be by changing spiral liter
Angle changes material movement direction and state so as to fulfill different mixing effects, while again can be by improving the number of polygon
Change exciting amplitude to improve excited frequency or change height of projection, it is simple in structure, it is easy for installation；In addition, the type vibrator
Barycenter rotate center coincidence, do not generate eccentricity excitation power to spring bearing in high speed rotation, shaft strength state compared with
It is good, noise pollution can be effectively reduced, extends bearing life.
