此類攪拌機(jī)多用于加藥反應(yīng)裝置，選型方法可參考槳式攪拌機(jī)，實(shí)際應(yīng)用中一般容器小于3噸的機(jī)架可以選配。

推進(jìn)式攪拌器是常用整體鑄造或焊接壓制而成，加工方便，結(jié)構(gòu)類似輪船的螺旋槳推進(jìn)器，常用三片槳葉構(gòu)成，俗稱螺旋槳攪拌器。

推進(jìn)式攪拌器選型一般直徑取容器內(nèi)徑的1/4-1/3，切向線速度可達(dá)5-15m/s，轉(zhuǎn)速一般為80-600r/min，最高轉(zhuǎn)速可達(dá)1750r/min，-般說(shuō)小直徑取高轉(zhuǎn)速，大直徑取低轉(zhuǎn)速。攪拌時(shí)能使所有物料在容器內(nèi)循環(huán)流動(dòng)，所起的作用以容積循環(huán)為主，剪切作用小，上下翻騰效果好，當(dāng)采用擋板或?qū)Я魍矂t軸向循環(huán)更好。

The mixer is mostly used for chemical feeding and reaction devices. As for the method for model selection, we can refer to that of the paddle mixer. In practical application, usually, a rack with a vessel less than 3 tons can be selected.

The propeller mixer is casted and welded as a whole and is easy to process. Its structure is similar to the propeller of a ship. It usually consists of three blades. The national standard for three-blade propeller mixers which are commonly known as propeller mixers is HG5- 222-65 in China.

As for model selection of propeller mixers, usually their diameters are 1/4 to 1/3 of the inner diameters of containers, their velocity can reach 5-15m/s, usually the rotation velocity is 80-600r/min,tangential linear velocity can reach 5-15m/s, usually the rotation velocity is 80-600r/min,the highest velocity can reach 1750r/min, usually the minor diameter uses the high rotation velocity and the major diameter uses the low velocity. The propeller mix can make all materials realize circular movements in the container. Its main function is volume circulation. The shearing action is small. The effect of up and down movements is good.If a bafle plate or guide cylinder is used, the axial circulation is better.

高排液量，低剪切性能，循環(huán)能力強(qiáng)，動(dòng)力消耗低。

推進(jìn)式攪拌器在低粘度、大容量均相、混合過(guò)程最能體現(xiàn)它節(jié)能的優(yōu)勢(shì)。

英文

High liquid discharge, low shear performance, strong cycle capability and low power consumption.

The push-type agitator can best reflect its energy-saving advantages in the low-viscosity, large -capacity homogeneous phase and mixing process.
