一、産品介紹
根據不同介質的物理學性質、容量、攪拌目的選擇相應的攪拌機，對化學反應速度、提高生産效率能起到很大的作用。一般使用于粥狀物料的攪拌，絮凝加藥攪拌
框式攪拌機，其結構比較堅固，攪動物料量大。如果這類攪拌機底部形狀和反應釜下封頭形狀相似時，通常稱爲錨式攪拌機。直徑較大，一般取反應器內徑的2/3~9/10，50~70r/min。使用于低粘度液體時，錨式葉輪的葉徑與罐徑比爲0.7～0.9，對于高黏度液體則爲0.8～0.95，轉速通常爲10～50r/min。攪拌機與釜壁間隙較小，有利于傳熱過程的進行，快速旋轉時，攪拌機葉片所帶動的液體把靜止層從反應釜壁上帶下來；慢速旋轉時，有刮板的攪拌機能産生良好的熱傳導。這類攪拌機常用于傳熱、晶析操作和高粘度液體、高濃度淤漿和沈降性淤漿的攪拌。
錨式、屬于同一類，統稱絮凝攪拌機，爲了增大攪拌範圍和帶走罐壁上的殘留物或液層，錨攪拌機的外廓要接近攪拌罐的內壁，其底部的形狀爲適應罐底的輪廓也有橢圓、錐形等。爲了增大對高粘度物料的攪拌範圍以及提高葉輪的剛性，還常常要在錨式及框式上增加一些立葉和橫梁，這樣使得錨框式的結構形狀出現了多種多樣。

二、桨型分类根据其形状大致可分为：锚式、椭圆框式、锥底框式、方框式以及锚框式等。

三、適用黏度
適用的黏度爲200～300Pa·s。

四、應用領域
搅拌机通常在低速下运行，在搅拌低粘度液体时不产生大的剪切力，因此它不适用于液-液和气-液分散。另一个方面，该种叶轮在罐内移动的流量大，水平回转流占支配地位，不具有良好的混合均一性，然而在罐壁附近的流速比其他叶轮，能达到大的传热膜系数，故常用于传热、晶析操作。另外，由于桨叶直径较大，且与罐底贴近，也常用它来搅拌高浓度淤浆和沉淀性淤浆。还有它也常用于高粘度流体的搅拌。

五、流動狀態
不同高度上的水平環向流。

六、結構
搅拌机与搅拌轴的连接方式类似于桨式，即叶轮与搅拌轴连接的一端制成半圆状的轴环，然后两侧叶片的两个半圆环用螺栓在搅拌轴上夹紧，同时用穿轴螺栓来固定叶片与搅拌轴。由于叶轮的外廓尺寸大，为便于装拆，叶片之间多数是螺栓连接，只有小型的采用铸造或焊接。叶轮以扁钢、角钢制造居多，为了提高叶轮的强度，也可采用加筋的钢板。

用途
主要用于给水厂、污水處理厂投加药剂的溶解搅拌。

‘That is very kind of her. But, indeed, I think we had better go.’ "Certainly," Frank responded. "Here we go again;" and there was another "Hip! hip! hurrah!" "Indeed he does! I don't like to say it, and I don't say he drinks 'too much', as they call it; but, Smith, he drinks with men who do! Oh, I admire him; only I do wish--" I got the words out in some form, that I believed Charlotte loved him deeply, as deeply, passionately, exaltedly, as ever a true woman loved a man-- The boy passed on whistling under his breath. Outside Hetty opened her message. Her fingers trembled slightly. "I have seen them; I have had them in my hands." Charlton was about to say more, but he checked himself in time. After all, the woman and her accomplice had not stolen the real gems, but the paste imitations. But Lawrence would be in a position to clear that point. And so, with the dissolution of our bodily organism, the music of consciousness would pass away for ever. Perhaps no form of psychology taught in the Greek schools has approached nearer to modern thought than this. It was professed at Thebes by two Pythagoreans, Cebes and Simmias, in the time of Plato. He rightly regarded them as formidable opponents, for they were ready to grant whatever he claimed for the soul in the way of immateriality and superiority to the body, while denying the possibility of its separate existence. We may so far anticipate the course of our exposition as to mention that the direct argument by which he met them was a reference to the moving power of mind, and to the constraint exercised by reason over passionate impulse; characteristics which the analogy with a musical harmony failed to explain. But his chief reliance was on an order of considerations, the historical genesis of which we shall now proceed to trace. Those of the servants and seamen who were not too excited by the escape of the hydroplane to hear, followed the Sky Patrol as they raced through the grove. Jeff, supported by Sandy and friends among the men, came more slowly, still unwell from the blow in a tender spot. “Well—think! If they can freeze lemonade, and get yellow ice cubes, they can freeze lime juice—even something darker—and get——” "Forward! Can't stop to pay attention to them," commanded the Lieutenant, in whom the battle-fever was burning. 'the Prisoners Had Too Much Solicitude About Their Garments to Think of Anything Else.' 185 The yells that soon rose from that thicket would have indicated that either a boy was being skinned alive or was having his face washed by his mother.
