Description
Technical field
The present invention relates to a kind of agitating device, particularly relate to a kind of agitating device produced for soft fixed grain all living creatures.
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.
Agitating device makes the medium such as liquid, gas forced convection and mixed uniformly machine.Traditional agitating device has manually and electronic dividing.The agitating device driven by motor alleviates the burden of people, and is greatly better than hand operated mixing device on stirring efficiency and effect.In productive life, have various electric mixing device, 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.
Modern manufacturing more and more pursues high efficiency and environmental protection, and the Laser Intensifying Processing Technology used in die surface processing, substantially increase wearability and the hardness of die surface, this has higher requirement to the free form surface technique of processing mold.In traditional processing method, Machining Free-Form Surfaces free abrasive used can realize good profiling degree, but the polishing efficiency of the cutting force that it can provide to processing high abrasion, high rigidity surface is very low, and rigid tool is difficult to form desirable face with work surface and contacts.Therefore, its use is greatly limited.
In order to realize having high rigidity after laser reinforcing, the material of mold freedom curved surface of high strength removes, and we have proposed the new method of soft fixed grain air-pressure grinding wheel finishing processing.
Soft fixed grain Pneumatic grinding wheel is a hollow hemisphere be made up of rubber matrix, and has certain thickness high polymer binder blend of abrasive particles (i.e. soft fixed grain group) at its surface bonding one deck.This Novel pressure emery wheel is made up of elastic caoutchouc base layer and bound abrasive grains mixed layer, and wherein rubber layer is matrix, bears the various service load of structure; Soft fixed grain group is working lining, plays the effect on cutting workpiece top layer.For this reason, the guarantee that the soft fixed grain group with superperformance is good material removal ability is made.
So-called soft fixed grain group (softness consolidation abrasives), refer in particular to the abrasive particle colony being bonded in Pneumatic grinding wheel matrix surface by high polymer cemented dose, it macroscopically can move freely unlike free abrasive, and on microcosmic, each abrasive particle is all subject to the resiliency supported of binding agent in all directions.
We devise the production of a closed mixer for soft fixed grain group for this reason, and wherein the sealing of mixer, negative pressure are one of key points of technology.
When design mixer, we have used freeze dryer and gas circulator.
The Vacuum Freezing & Drying Technology that freeze dryer (lyophilizer or freeze dryer) originates from the twenties in 19th century experienced by decades fluctuating and after hovering, made significant progress in last 20 years.Enter 21 century, the advantage that vacuum freeze drying technology relies on other drying means incomparable, more and more be subject to the favor of people, except being used widely in medicine, biological products, food, blood product, active material field, its application scale and field are also in constantly expanding.For this reason, vacuum freeze drying will become the important application technology of 21 century.
Gas circulator refers to the vavuum pump for gas circulation, possesses each one of the air exhaust nozzle of one-in-and-one-out, exhaust nozzle, and can continue to form vacuum or negative pressure in import department; Exhaust nozzle place forms pressure-fired; Working media is mainly gas, is mainly used in a kind of miniature instrument of gas circulation.Gas circulator is a branch of minipump classification by use, minipumps (herein means the vavuum pump of diaphragm type) all substantially all can be used for gas circulation, so minipump is also called gas circulator by popular in gas circulation industry.The operation principle of gas circulator: the circular motion of motor, the barrier film of pump inside is made to do reciprocating by mechanical eccentric device, thus the air in the pump chamber of fixed volume is compressed, stretch formed vacuum (negative pressure), pressure differential is produced at pump bleeding point place and external atmosphere pressure, under the effect of pressure differential, gas pressure (suction) is entered pump chamber, then discharges from exhaust outlet.
