使液體、氣體介質(zhì)強迫對流并均勻混合的器材。拌和器的類型、尺寸及轉(zhuǎn)速，對拌和功率在整體活動和湍流脈動之間的分配都有影響。一般說來，渦輪式拌和器的功率分配對湍流脈動有利，而旋槳式拌和器對整體活動有利。關(guān)于同一類型的拌和器來說，在功率耗費相同的條件下，大直徑、低轉(zhuǎn)速的拌和器，功率首要耗費于整體活動，有利于宏觀混合。小直徑、高轉(zhuǎn)速的拌和器，功率首要耗費于湍流脈動，有利于微觀混合。拌和器的擴大是與工藝過程有關(guān)的復(fù)雜問題，至今只能經(jīng)過經(jīng)驗擴大，根據(jù)取得的擴大判據(jù)，外推至工業(yè)規(guī)模。
A device for forced convection and uniform mixing of liquid and gas media. The type, size and speed of mixer have influence on the distribution of mixing power between the whole activity and turbulence fluctuation. Generally speaking, the power distribution of Turbo mixer is beneficial to turbulence fluctuation, while the propeller mixer is beneficial to overall activity. For the same type of mixer, under the condition of the same power consumption, for the mixer with large diameter and low rotation speed, the power is mainly consumed in the overall activity, which is conducive to the macro mixing. For the mixer with small diameter and high rotating speed, the power is mainly consumed in turbulence fluctuation, which is beneficial to micro mixing. The expansion of the mixer is a complex problem related to the process. Up to now, it can only be expanded by experience. According to the obtained expansion criteria, it can be extrapolated to the industrial scale.
拌和器是用來拌和用的設(shè)備，通常會用它拌和物料，為了提高設(shè)備的使用效率，在放料時需求留意哪些？
Mixer is used for mixing equipment. It is usually used to mix materials. In order to improve the use efficiency of the equipment, what should be paid attention to when placing materials?
1、它在加料時要當(dāng)心，應(yīng)盡量避免空罐加熱料或許熱罐加冷料，過大的溫差沖擊關(guān)于琺瑯的功能有一些影響，一起應(yīng)該確保不會讓堅硬固體物體調(diào)入釜內(nèi)，關(guān)于不必參加大塊硬質(zhì)物料，應(yīng)破壞后參加。
1. It should be careful when adding materials. It should try to avoid heating materials in empty tanks or cold materials in hot tanks. Too large temperature difference impact has some impact on the function of enamel. Together, it should be ensured that hard solid objects will not be transferred into the kettle. As for large hard materials that do not need to participate, they should be added after damage.
2、運轉(zhuǎn)過程中應(yīng)該留意，經(jīng)過夾套對設(shè)備進行升溫時，要徐徐加壓升溫。要預(yù)先通入0.1MP的壓力，保持一刻鐘后，再慢慢通入蒸氣達操作壓力。
2. During operation, it should be noted that when the temperature of the equipment is raised through the jacket, it is necessary to slowly increase the pressure and temperature. The pressure of 0.1mp shall be applied in advance, and after a quarter of an hour, the steam shall be applied slowly to reach the operating pressure.
3、運轉(zhuǎn)中，要留意拌和器法蘭、接盤、人孔及填料箱的密封狀況，如發(fā)現(xiàn)泄漏應(yīng)采納辦法。
3. During operation, pay attention to the sealing conditions of mixer flange, adapter plate, manhole and stuffing box, and take measures in case of leakage.
4、關(guān)于出料時應(yīng)該留意，如遇拌和器堵塞，不能用金屬器具鏟打，可用竹竿或塑料棒、木棒悄悄捅開，反響結(jié)束需求放冷時，要待溫度自然下降到一些程度后再向夾套內(nèi)通放冷水。
4. When discharging, it should be noted that if the mixer is blocked, it can not be shoveled with metal tools, but can be quietly poked open with bamboo or plastic rods or wood rods. When the response is over and the cooling is required, the cold water should be put into the jacket after the temperature naturally drops to some extent.
所以說，拌和器放料的時候，需求留意觀察機器的使用狀況，根據(jù)狀況再進行加料，檢查配件。
Therefore, when the mixer is discharging, it is necessary to pay attention to observe the use of the machine, add materials according to the condition, and check the accessories.
