The main types of clay mixers
The main types of clay mixers:
① propeller mixers
From 2 to 3 propeller propeller blades, the work of high speed, the outer edge of the blade peripheral speed is generally 5 ~ 15m / s. Propeller-type agitator mainly produces axial flow, resulting in a large amount of circulation, suitable for mixing low viscosity (<2Pa · s) liquid, emulsion and solid particles less than 10% of the suspension. The shaft of the stirrer can also be inserted horizontally or obliquely into the tank. At this time, the circulation loop of the liquid flow is asymmetrical, which can increase the turbulence and prevent the liquid level from sagging.
② Turbine mixers
By the installation of 2 to 4 flat or curved blades on the horizontal disc. The outer diameter of the blade, the ratio of width to height, generally 20: 5: 4, the circumferential speed is generally 3 ~ 8m / s. Turbine in the rotation caused by a high degree of turbulent radial flow, suitable for gas and non-reciprocal liquid dispersion and liquid-liquid reaction process. The viscosity of the agitated liquid is generally not more than 25 Pa · s.
③ paddle mixers
There are two types of paddle and oblique paddle. The paddle stirrer consists of two straight blades. The ratio of diameter and height of the blade is 4 ~ 10, the circumferential velocity is 1.5 ~ 3m / s, and the radial velocity is smaller. The two blades of the oblique paddle stirrer are reversed by 45 ° or 60 °, resulting in axial flow. The paddle stirrer has a simple structure and is commonly used for the mixing of low viscosity liquids and the dissolution and suspension of solid particles.
④ anchor type mixers
The outer edge of the blade is consistent with the inner wall of the stirring tank, with only a small gap between them, which can remove the viscous reaction product attached to the groove wall or the solid material deposited on the bottom of the tank to maintain good heat transfer effect. The peripheral velocity of the outer edge of the blade is 0.5 ~ 1.5m / s, which can be used to agitate the Newtonian fluid and the plastic fluid with viscosity up to 200Pa · s (see the viscous fluid flow. Of the stagnant area.
⑤ Ribbon Mixer
The outer diameter of the ribbon is equal to the pitch, and is used to stir the high viscosity liquid (200 to 500 Pa · s) and the quasi-plastic fluid, usually in a laminar flow state.
⑥ magnetic mixers
Corning digital heaters come with a closed-loop knob to monitor and adjust the stirring speed. The microprocessor automatically adjusts the motor power to accommodate water, viscous solutions and semi-solid solutions.
⑦ magnetic heating mixers
Corning digital heating agitators with optional external temperature controller (Cat. No. 6795PR), they can also monitor and control the temperature in the container.
⑧ folding blade mixers
According to the physical properties of different media, capacity, stirring the purpose of selecting the appropriate mixing,] to promote the chemical reaction speed, improve production efficiency can play a significant role. Folding turbine agitator is generally adapted to the reaction of gas and liquid phase, and the number of revolutions of the stirrer should generally be 300r / min or more.
⑨ variable frequency double mixer
Variable frequency mixer base, pole, the use of patented motor technology as a whole. Patent chuck, no loose, no swing, will not fall off, safe and reliable. Chrome struts, under the coarse on the fine, strong steel, reasonable structure. With easy to move, light weight and other advantages. Suitable for all kinds of small containers.
