Abstract
The invention relates to a mixing stirrer with a paddle with airflow driven by air pressure, which is structurally distinguished from other stirrers. Gas is blown from the outside by an air inlet pipe welded on a kettle body, enters a hollow stirring paddle connected to the air inlet pipe by a one-way valve and finally, is discharged by air holes on a paddle. The gas can act on fluid directly; and moreover, reverse thrust can be generated to drive the stirrer to work so as to achieve double stirring (the structural drawing is shown in the accompanying drawing of the abstract of a specification). The mixing stirrer with the paddle with the gas driven by the air pressure is designed aiming at the energy consumption, the production cost and the stirring effect in the stirring process. The mixing stirrer with the paddle with the airflow driven by the air pressure has the characteristics of making up some defects of other stirrers, simplifying the structure of equipment and lowering the manufacturing cost, so that the installation of the stirrer is diversified. The occurrence of leakage and pollution when the reactions of oxidation, hydrogenation and the like are carried out in the processes of petrochemical engineering, organic synthesis and food processing can be better avoided.
Description
Technical field:
Stir and be widely used in forming by blade, shaft, drive unit and sealing device etc. in the industry such as petrochemical industry, biology, food, pharmacy.Stirring has the form of two of liquid-liquid, liquid-solid, solution-airs etc. or multinomial medium.The purpose that stirs is that liquid dissolves to stirring, dispersion, fermentation, crystallization, reaction etc.At present, the development of the mixing plant of China is rapid, and various new and effective agitators emerge in an endless stream, and novel agitator and stirring means are used widely.
Background technology:
Mechanical agitation is to utilize shaft to drive a kind of mechanical device of the rotation of blade to still inner fluid input mechanical energy.Multiple agitators such as the six straight leaf disc turbine types that are widely used almost can be accomplished all stirring operations effectively, and its advantage has bigger shearing force, can make fluid micellar disperse very carefully, are applicable to that low pressure, low viscosity mixes to the fluid of medium viscosity; But too high rotating speed can make vacuum side of blade produce air pocket, reduce mass-transfer efficiency, and too high shearing force is unfavorable for the cultivation of microorganism; Also some agitator needs the high operating modes of ask for something such as the gentle speed of high rotational speed in order to reach production requirement, and this has just increased production cost and energy resource consumption.
Compare with mechanical agitation, gas agitation has stable operation, simple in structure, low power consumption and other advantages, but too high gas speed also is unfavorable for mass transfer, and mass tranfer coefficient is descended.
The present invention drives the motor driven that replaces in the past with air pressure; Carry out dual stirring with gas and blade convection cell; Can alleviate the defective that stirring brought of single form like this; Can be issued to good mixing effect in the gentle speed of low rotating speed, invention this time is mainly used in food industry and chemical processes such as GAS ABSORPTION, oxidation, hydrogenation, polymerization, and the mechanical and dual stirring of gas can improve stirring efficiency greatly; Cut down the consumption of energy, under certain gentle speed of rotating speed, can give full play to the advantage of mechanical agitation and gas agitation.
Summary of the invention:
The objective of the invention is to overcome in the existing agitator because the shortcoming that power consumption is big, heat radiation is many, device structure is complicated, cost is high, and simplified equipment can avoid labyrinth that stirring liquid is caused unnecessary pollution.Be issued to higher stirring efficiency in low consumption.
Air pressure drives air-flow-blade mixing agitator and structurally is different from other agitator.Stir by the direct convection cell of driven by motor shaft; Become by the outside and blast gas through the breather pipe that is welded on the cylindrical shell; Be connected the hollow paddle on the breather pipe through the check valve entering; Discharged by the pore that designs according to operating mode on the blade at last, not only gas can directly act on fluid, and can produce propulsive thrust and drive agitator and carry out work and reach dual stirring.Blade back side institute's open pore and level are angled avoids spraying gas by the back leaf baffle; Breather pipe directly is welded on the cylindrical shell; Motor connects the movable sealing structure of shaft before so just replacing with static seal structure; Not only effectively simplified device structure; Reduce manufacturing cost, make agitator installation variation, more can avoid in petrochemical industry, organic synthesis, food processing process, carrying out producing when oxidation, hydrogenation etc. are reacted and reveal and pollution; Gas drives agitator work can reduce the heat that driven by motor produces, and the gas of being gone out by pore simultaneously also acts on simultaneously and stirs liquid and can effectively control the raising stirring efficiency to the air pocket that is produced behind the blade back.Stir at axial convection cell, improve stirring efficiency if adopt the Rushton turbine can also on the disk of turbine, open suitable pore, make stirring more abundant according to the production needs.
Because the simplification of structure has not only reduced manufacturing requirements.More can reduce production costs to reach and make rational use of resources, exchange high value for low energy consumption.
Description of drawings:
With six straight leaf disc turbine stirrers is example:
Fig. 1 air pressure drive air-flow-blade mixing agitator installation diagram (1, air inlet pipe, 2, kettle, 3, Non-return air valve, 4, the band distributed pores and drive the paddle of pore)
Fig. 2 air pressure drives the B-B of air-flow-blade mixing agitator to view
The specific embodiment:
The gas of choosing proper temperature and pressure according to different operating modes as shown in Figure 1 is fed through breather pipe (1) by the outside; Process unidirectional breather valve (3), the distributed pores that sets that gets on the hollow stirrer paddle (4) is discharged with the driving pore, and distributed pores discharge gas directly acts on liquid and plays distribution and stirring action; Drive pore and discharge gas generation rotary impetus; Gas is when promoting stirrer paddle (4) rotation, and the gas that ejects is uniformly distributed in the liquid, and the stirrer paddle of rotation (4) promotes liquid agitation and plays mechanical agitation; Made full use of the positive and negative kinetic energy of air pressure, effectively energy savings.
