Paddle mixer (1) Category: flat leaf blade stirrer and flap paddle stirrer (2) Features: low speed, viscosity is more sensitive, not too long blades. (3) Application: medium low viscosity liquids. Mainly used in chemical dissolution and mixing. (4) The structure of the paddle mixer paddle mixer structure is simple, its blades are generally made with flat, ribbed need when strong enough, single ribbed effect 2.3.2 propeller stirrer (1) Features : The volume of the main loop, circulation rate, small shearing, good upper and lower churn effect. (2) Applications: Pharmacy dissolved and suspended operation. (3) The propeller stirrer general structure of cast iron, cast steel as a whole, sometimes with welding. 2.3.3 turbo agitator (1) Category: Open-type and disk types, there are flat leaf blades, curved leaf and flap (2) features: liquid can be uniformly changed by the movement in the vertical direction into a horizontal direction movement, since the turbine speed flow flowing tangentially spread out, whereby vigorous agitation throughout the liquid. (3) Applications: widely used in fast-dissolving stirrer and emulsified operations (4) turbo agitator structure 2.3.4 Other types of stirrer also other types of frame type agitator, anchor, screw, ribbon and so on, not in this repeat. Annex 2.4 blender attachment stirrer main baffle or draft tube. The reason is easy to set swirl flow stirrer speed is high, the influence of the stirring effect, combined with vigorous swirling liquid vortex effect, have an impact on the role of the agitator shaft, thus affecting the life of the agitator. DK produced side-stirring apparatus using a wide range, in fermentation, food engineering, desulfurization tower, petrochemical, titanium dioxide crystal cans, paper and other industries are widely used. 1, the side into the mixing device is mounted on the side wall of the device, greatly reducing the stirring shaft, the stirring device to enhance stability. 2, side-stirring device during the installation have a horizontal and vertical angle, angle is generally not too large, can be formed to promote the circulation of material in the mix the whole body of the tank. 3, side-stirred with a mechanical seal requires very high, our choices are set side-mounted stirring special double mechanical seal. Ensure the tightness of the device. Mechanical seal is balanced, double-end cartridge mechanical seal. The mechanical seal with spring built-in design, media reach of the spring, to avoid the failure of the factors leading to the spring of the spring corrosive medium and medium particles and clogging impurities such as a spring, extended service life. And the spring is placed in the stationary ring side, to a certain extent, to overcome the error is not connected to the flange surface perpendicular to the shaft. Mechanical seal for the friction surface and other surface design that avoids contaminant particles remain in the sealing surface, the particles can be contained in the medium without flushing harsh conditions used, to reduce the wear rate of the friction surface. And its friction material selection silicon carbide (tungsten carbide or tungsten carbide, tungsten carbide on silicon carbide), this material is more resistant than other materials, but also extend the life of DK stirrer biopharmaceutical industry has done a very many success stories, especially in the most important is in this bio-fermentation process, the biological fermentation process requires gas, solid, uniform mixing of liquid three. First biopharmaceutical fermentation blender is used in combination with a multi-layer, so as to achieve gas, solid and liquid three uniform use, after the blender is a blender four broad leaf axial cycle, running up to achieve very good axial mixing cycle, so that the material reaches uniformity, all the stirring is polished, very bright, is generally the blender is using two layers. In the process of fermentation, the lower agitator is crucial, it is ventilated, the gas should be evenly distributed on the inside, asymmetric parabolic disk turbine agitator, it has a great advantage to be able to make bubbles FIG dispersion stirrer, is also bubbled achieve Good cut, stirred reduce energy consumption, in addition to the entire blade forming is a forming process, there is no dead zone turbo agitator map, while the bio-fermentation inside this requirement sealing is very strong, in the mechanical seal this one has our unique place, our mechanical seal is quick - mechanical structure, and dry friction, there will be no accumulation of the entire material without contamination, the entire tank after contamination material will destroy the dosing stirrer map, we choose different types of agitation for different processes, in which the entire field of biological engineering, we can do an agitator than the same industry manufacturers to achieve 30% energy saving for customers saving the entire operating costs and enhance the competitiveness of customers turbo agitator Figure |.
