Abstract
The invention provides an agitator with a variable diameter, comprising a wheel hub connected with an agitating shaft, fixed blades, sliding blades and elastic elements, wherein the fixed blades are fixedly connected with the wheel hub in a welding or bolt connection manner and other manners; the sliding blades and the parts of fixed blades are sleeved together; the sliding blades can slide along the fixed blades; one end of each elastic element is fixedly arranged on each fixed blade or the wheel hub and the other ends of the elastic elements are fixedly arranged on the sliding blades; and the parts of sliding blades are sleeved with the fixed blades all the time due to the restriction of the elastic element. When the agitator is operated, the sliding blades overcome the pull force of the elastic elements due to the effect of centrifugal force to slide outwards along the fixed blades, so that the diameter of the agitator is increased; when the agitator is stopped, the sliding blades slide inwards due the pull force of the elastic elements and the diameter of the agitator is reduced and recovered to the previous state; and therefore, the agitating resistance and the starting power of the agitator are reduced when the agitator is restarted. The agitator with the variable diameter is suitable for solid-liquid mixing agitation with easily deposited or hardened solid phase and the agitation of materials with viscosity gradually reduced due to the agitation effect.

At present, according to different application scenarios, various dissimilar agitators are arranged.But existing agitator is the agitator of fixed diameter mostly, and stirrer diameter is immutable in whipping process.Existing fixed diameter agitator can satisfy the needs that most of industrial production material stirs, but has open defect at some occasion fixed diameter agitator.The solid-liquid mix and blend occasion that deposits easily even harden in solid phase, have a power failure or special process need to need again to start after stopping to stir a period of time when stirring when running into, because of solid precipitation or harden, the fixed diameter agitator probably causes stirring resistance and increases and can't start because being buried by solid phase, even burns stirring motor.Make it when being buried by solid phase, to start smoothly if reduce the diameter of agitator, then can reduce not reach because of stirrer diameter stirring intensity or the effect of technological requirement.The material that some colloid material or other viscosity are higher in addition is constantly liquid feeding dilution in whipping process, and the viscosity of material can reduce in whipping process gradually, the agitator of certain diameter, and its required power of agitator reduces along with the reduction of material viscosity.The agitator of fixed diameter, if it just satisfies stirring intensity after material viscosity reduces, power is fully used, then high because of material viscosity when the stirring startup, overloading easily occurs even can't start in agitating device; If change stirrer diameter little or be equipped with the large motor of power headroom, then agitator does not reach mixing effect or the motor operational efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of agitator of variable-diameter, overcome former agitator and in whipping process, can't change the shortcoming that the stirring diameter satisfies mixing effect.
A kind of agitator of variable-diameter is characterized in that: comprise the wheel hub, fixed blade, sliding blade and the flexible member that are connected with shaft, fixed blade adopts welding or bolt connecting mode to be fixedly connected with wheel hub; Sliding blade partly is linked in fixed blade, and sliding blade can slide along fixed blade; Flexible member one end is fixed on the fixed blade or on the wheel hub, the other end is fixed on the sliding blade; Sliding blade remains part and fixed blade fit because of the constraint of flexible member.When sliding blade was linked in the fixed blade outside, this moment, sliding blade was provided with the fit inner chamber, and flexible member is arranged on the outside of fixed blade; When sliding blade was linked in the inside of fixed blade, flexible member was arranged in the inner chamber of fixed blade.
Preferably, wheel hub is monoblock type or dissection type steel wheel hub, and the multi-disc fixed blade is weldingly fixed on the wheel hub, can have certain inclination angle.Two groups or three groups blades of agitator operated by rotary motion, a fixed blade and a sliding blade are one group, and mixing arm arranges symmetrically with respect to the wheel hub center, and blade tilt is 30 degree or 45 degree.
Preferably, flexible member is the steel extension spring, and every group of blade is symmetrical arranged two springs.The spring rate centrifugal force that sliding blade can produce according to the maximum slippage of sliding blade with when rotating carries out calculative determination.Spring was in relaxed state when agitator was in the minimum diameter state.
Preferably; the gap of sliding blade and fixed blade fit part is less than 1mm; sliding blade is provided with the flexible rings such as felt collar, cushion rubber by the hub end end face, prevents that effectively solid particle or gluey material from entering in the gap of fixed blade and sliding blade fit part, affects the normal slip of sliding blade.
Preferably, when agitator was in the diameter maximum rating, the length of sliding blade and fixed blade fit part was not less than hub diameter, the blade stiffness when stirring with assurance.
Variable-diameter agitator of the present invention is after startup; agitator increases stirrer diameter automatically by the centrifugal force of himself; agitator automatically returns to the minimum diameter state by the pulling force of flexible member after shutting down; need not the power set of additional adjustment diameter; need not in the stirrer diameter adjustment process to shut down, need not manually-operated.Useful technique effect of the present invention is: agitator can change diameter in whipping process, and in the solid-liquid mix and blend occasion that solid phase easily deposits or hardens, agitator starts with less diameter state, has effectively reduced the stirring resistance, has reduced starting power; Behind solid phase dispersion, the sliding blade of agitator outwards slides under the effect of centrifugal force, and stirrer diameter increases, and has effectively strengthened stirring intensity, has strengthened mixing effect.In the occasion that material viscosity reduces with stirring action, the variable-diameter agitator has same beneficial effect.The variable-diameter agitator can adapt to that solid phase easily deposits or the intermittent stirring operation of the material that the solidliquid mixture that hardens and viscosity reduce with stirring action, can satisfy some and require intermittent special process requirement of stirring.
