Description
Technical field
The present invention relates to a kind of mixer, particularly relate to a kind of mixer with rotatable nozzle.
Background technology
Stirring is the production technology that the mankind comparatively early grasp, and two or more different materials can be made to disperse mutually among each other, thus reach Homogeneous phase mixing; Also heat transfer and mass transport process can be accelerated.In the industrial production, stirring operation be chemically industry start, around food, fiber, papermaking, water treatment etc., as technical process a part and be widely used, its main purpose is mass transfer or diabatic process in acceleration system.Stirring technique have also been obtained development and application in the production of oil industry, especially in the design and devdlop of some large-scale storage tanks, can make that the liquid storage in storage tank mixes, homogeneous temperature, promotes dilution, dissolves, dispersion, and strengthening heating, prevents layering and precipitation.In whipping process fluid flowing and mixing very complicated, its design mainly relies on semi-empirical approach.
Stirring operation is divided into mechanical agitation and airflow stirring.Airflow stirring utilizes gas sparging by liquid level, produces stirring action to liquid, or liquid produces convection circulation to make bubble rely on effect of increasing to promote.Compared with mechanical agitation, only the effect of bubble is to the stirring of liquid, is especially difficult to use for high viscosity liquids more than several thousand milli handkerchief seconds.But airflow stirring movement-less part, so at process corrosive liquids, is than conveniently during the stirring of the reaction liquid under high-temperature and high-pressure conditions.Mechanical agitation, by rotating the changes mechanical energy of paddle kinetic energy fluidly, forms the overall flow in still, thus completes the process of still inner transmission matter and heat transfer.In the industrial production, most stirring operation is all mechanical agitation, based in, the mixing plant of low-pressure vertical steel vessel.
Mixer makes the medium such as liquid, gas forced convection and mixed uniformly machine.Traditional mixer has manually and electronic dividing.The mixer driven by motor alleviates the burden of people, and is greatly better than hand blender on stirring efficiency and effect.In productive life, have various electric blender, little only has cup size, large just such as cement transporter.Mixing plant being of wide application in the industrial production, especially in chemical industry, a lot of Chemical Manufacture applies stirring operation all more or less.Why extensive like this range of application of mixing plant is, and the controlled range also because of mixing plant operating condition (as concentration, temperature, the time of staying etc.) is comparatively wide, 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 mix, the mixer of processing such as reacting, disperse, dissolve, be modified is all provided with paddle usually, and drive paddle rotate in material barrel thus mix the material in material barrel, stir by drive unit, because most of material viscosity is high, in order to uniform by mixing of materials, stirring, to the more complicated of the structural design of paddle.When relating to solid-liquid phase and stirring, in the process stirred, material barrel bucket wall is easy to be stained with impurity, after impurity buildups gets up, pollution is brought to material, can not be even by material stirring well, immediately below paddle, region is also difficult to be stirred to simultaneously, thus makes the effect stirred not be very desirable.
Summary of the invention
In order to solve the deficiencies in the prior art, solving problem bucket wall stirring liquid delay condensation, devising one and can extract stirring liquid, by the agitating device of nozzle comprehensive douche can back and forth wall.
For achieving the above object, the technical solution adopted in the present invention is: a kind of mixer with rotatable nozzle, comprise agitator, sealing ring, rotating shaft, cross bar and blade, cross bar to be disposed across on agitator and by bolt and agitator edge affixed, 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 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 affixed, fixed axis upper end is provided with one section of external screw thread;
Described axle sleeve is sleeved on fixed axis, and the upper end of axle sleeve is provided with one section of internal thread, coordinates with the external screw thread of fixed axis upper end;
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, and axle sleeve outer ring is provided with balancing weight with the position of water pump symmetry, 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 first jet and a pair second nozzle, and the liquid in nozzle is along the ejection of rotating shaft tangential direction, and first jet is contrary with second nozzle fluid 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 cut out of first jet and the unlatching of second nozzle, and the second contact-making switch controls the cut out of second nozzle and the unlatching of first jet;
The bottom of described rotating shaft connects motor by decelerator;
It is two right that described ultrasonic generator is provided with, and is symmetrically distributed in top, outer ring and the bottom, outer ring of barrel wall.
Compared with prior art, the present invention has the following advantages:
1, mixer is when stirring, and the material in agitator rotates along with the rotation of stirring vane, and blade stirs exists mixing inefficient zone, and the linear velocity being such as positioned at the material immediately below spindle central is minimum, and material is often 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 invention directly extracts stirring liquid by flexible pipe, the effective material movement promoted near flexible pipe import department, the stirring liquid near flexible pipe import is made to produce tangential shear effect, improve effect and the efficiency of stirring, make the mixing effect of material more desirable.
2, mixer stir time or mixer withdraw from service time, bucket wall is often detained and much stirs liquid, stirs liquid and easily condenses into solid, and these solid particles are shed to stir in liquid and often cause the material after stirring uneven; The present invention is ejected on barrel wall by nozzle after being extracted by stirring liquid by the water pump that the second rotating shaft lower end is installed, and is rinsed by the solid that bucket wall condenses, maintains the mixing effect that improve material while barrel wall cleans.
3, nozzle of the present invention adopts nozzle ring, the first contact-making switch is triggered after the reaction force that first jet ejection liquid produces can drive rotation second axis of rotation to top of the second rotating shaft, first contact-making switch controls first jet and cuts out, open second nozzle simultaneously, the reaction force that second nozzle ejection liquid produces drives the second rotating shaft to rotate backward, thus move up and down while realizing the second axis of rotation, the region that nozzle sprays can cover whole bucket wall, avoids the problem that part dead angle does not flush.
4, the symmetrical supersonic generator of stirring barrel both sides of the present invention setting, can produce the effect stirring material and smash bonding impurity when in use, thus improve mixing effect.
