Description

A kind of mixer with rotatable nozzle

Technical field

The utility model relates to a kind of mixer, relates in particular to a kind of mixer with rotatable nozzle.

Background technology

Stirring is the production technology that the mankind early grasp, and can make two or more different materials disperse mutually among each other, thereby reach even mixing; Also can accelerate to conduct heat and mass transport process.In industrial production, stirring operation is from chemical industry, and around food, fiber, papermaking, water treatment etc., as the part of technical process and be widely used, its main purpose is mass transfer or diabatic process in the acceleration system.Stirring technique also is developed and applies in the production of oil industry, especially in the design of some large-scale storage tanks and application, can make that liquid storage in storage tank mixes, temperature is even, promotes dilution, dissolves, disperses, and the strengthening heating, prevent layering and precipitation.In whipping process fluid flow and mix very complicated, the main semi-empirical approach that relies on of its design.

Stirring operation is divided into mechanical agitation and airflow stirring.Airflow stirring is to utilize gas sparging to pass through liquid level, and liquid is produced to stirring action, or makes bubble rely on effect of increasing to promote liquid to produce convection circulation.With mechanical agitation, compare, the only stirring of the effect of bubble to liquid, especially be difficult to use for the high viscosity liquid of several thousand milli handkerchiefs more than second.But the airflow stirring movement-less part, so, at the processing corrosive liquids, during the stirring of the reaction liquid under high-temperature and high-pressure conditions, be more easily.Mechanical agitation changes into the mechanical energy of paddle by rotation the kinetic energy of fluid, forms the overall flow in still, thereby completes the process of still inner transmission matter and heat transfer.In industrial production, most stirring operation is all mechanical agitation, in take, the mixing plant of low-pressure vertical steel vessel is as main.

Mixer is to make the medium forced convections such as liquid, gas mixed uniformly machine.Traditional mixer has manually and electronic dividing.Alleviated people's burden by electric motor driven mixer, and greatly be better than hand blender on stirring efficiency and effect.Various electric blender are arranged in productive life, and little only have the cup size, large just such as cement transporter.In mixing plant being of wide application in industrial production, especially chemical industry, a lot of Chemical Manufacture is all being applied stirring operation more or less.Why extensive like this range of application of mixing plant is, and also the controlled range because of mixing plant operating condition (as concentration, temperature, the time of staying etc.) is wider, can adapt to diversified production again.

At present, on the market more common to many components solid-solid phase, solid-liquid phase, liquid-liquid phase material mixed, the mixer of reaction, dispersion, dissolving, the processing such as modified all is provided with paddle usually, thereby and drive paddle by drive unit and rotate the material in material barrel is mixed, stirs in material barrel, because most of material viscosity are high, for uniformly by mixing of materials, stirring, to the more complicated of the structural design of paddle.When relating to the solid-liquid phase stirring, in the process stirred, material barrel bucket wall is easy to be stained with impurity, after impurity is piled up, bring pollution to material, can not be well that material stirring is even, under the while paddle, zone also is difficult to be stirred to, thereby make the effect of stirring, is not very desirable.

The utility model content

In order to solve the deficiencies in the prior art, solve and to stir liquid on the bucket wall and be detained the problem of condensing, designed and a kind ofly can extract stirring liquid, by the agitating device of the comprehensive douche can back and forth of nozzle wall.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of mixer with rotatable nozzle, comprise agitator, sealing ring, rotating shaft, cross bar and blade, cross bar is disposed across on agitator and is affixed by bolt and agitator edge, agitator bottom centre is provided with manhole, and the outer ring of rotating shaft is provided with sealing ring, and rotating shaft is through manhole, sealing ring is fixed on the agitator inner bottom surface, and blade is contained in the upper end of rotating shaft; The described mixer with rotatable nozzle also comprises fixed axis, axle sleeve, nozzle ring, water pump, balancing weight, flexible pipe, decelerator, motor and supersonic generator;

Described fixed axis top and cross bar are affixed, and the fixed axis upper end is provided with one section external screw thread;

Described axle sleeve is sleeved on fixed axis, and the upper end of axle sleeve is provided with one section internal thread, with the external screw thread of fixed axis upper end, coordinates;

Described nozzle ring is fixed in the upper end, outer ring of axle sleeve, and water pump is fixed on the lower end, outer ring of axle sleeve, on the axle sleeve outer ring, with the position of water pump symmetry, is provided with balancing weight, the water inlet connecting hose of water pump, and the delivery port of water pump is connected with nozzle ring by flexible pipe;

Described nozzle ring is provided with a pair of the first nozzle and a pair of second nozzle, and the liquid in nozzle is along the ejection of rotating shaft tangential direction, the first nozzle and second nozzle fluid opposite direction; The top, outer ring of described fixed axis and bottom are respectively equipped with the first contact-making switch and the second contact-making switch, and the first contact-making switch controls the unlatching with second nozzle of cutting out of the first nozzle, and the second contact-making switch controls the unlatching with the first nozzle of cutting out of second nozzle;

The bottom of described rotating shaft connects motor by decelerator;

Described ultrasonic generator is provided with two pairs, is symmetrically distributed in top, outer ring and the bottom, outer ring of barrel wall.

Compared with prior art, the utlity model has following advantage:

1, mixer is when stirring, and the material in agitator rotates along with the rotation of stirring vane, and blade stirs and has mixing inefficient zone, and such as the linear velocity minimum that is positioned at the material under spindle central, material often is difficult to by uniform stirring herein; The existence of mixing inefficient zone has had a strong impact on mixing quality and efficiency, water pump of the present utility model directly extracts stirring liquid by flexible pipe, effectively promoted near the material movement of flexible pipe import department, make near the stirring liquid of flexible pipe import produce tangential shear effect, improved the effect and the efficiency that stir, made the mixing effect of material more desirable.

2, mixer stir the time or when the mixer withdraw from service, a bucket wall tends to be detained a lot of stirring liquid, stirs liquid and easily condenses into solid, these solid particles are shed to stir in liquid and often cause the material after stirring inhomogeneous; After the water pump that the utility model is installed by the second rotating shaft lower end will stir liquid and extract by nozzle ejection to the bucket wall, the solid condensed on the bucket wall is rinsed, improved the mixing effect of material when having kept barrel wall clean.

3, nozzle of the present utility model adopts nozzle ring, rotation the second rotating shaft that the reaction force that the first nozzle ejection liquid produces can drive the second rotating shaft turns to triggering the first contact-making switch behind top, the first contact-making switch controls the first nozzle and cuts out, open second nozzle simultaneously, the reaction force that second nozzle ejection liquid produces drives the second rotating shaft and rotates backward, thereby realize when the second rotating shaft is rotated moving up and down, the zone of nozzle ejection can cover whole bucket wall, the problem of having avoided the part dead angle not flush.

4, the symmetrical supersonic generator that stirring barrel of the present utility model both sides arrange, can produce the effect that stirs material and smash bonding impurity when in use, thereby improve mixing effect.
