Cement, fly ash, mineral powder and other powder materials are usually used to produce concrete. Most of these powder materials are stored in the cement silo of automatic mixer truck, which is rainproof and moisture-proof. Generally, when purchasing mixing plant facilities, it is equipped with automatic mixer, and a reasonable number of cement silos are matched with your production needs.

日常使用的自動(dòng)攪拌車水泥倉(cāng)也比較簡(jiǎn)單，但在使用過程中，生產(chǎn)的影響是材料的管理，如材料過多，過少，導(dǎo)致材料破裂或缺乏。因此，典型水泥筒倉(cāng)中更重要的部件是液位計(jì)。水泥倉(cāng)用于避免爆炸和材料短缺。

Daily use of automatic mixer cement silo is also relatively simple, but in the process of use, the impact of production is the management of materials, such as too much or too little material, resulting in material rupture or lack. Therefore, the more important component in a typical cement silo is the level gauge. Cement silo is used to avoid explosion and material shortage.

自動(dòng)攪拌車的水泥倉(cāng)液位計(jì)大多采用開關(guān)式液位計(jì)，安裝在水泥筒倉(cāng)的底部。它具有結(jié)構(gòu)合理，性能可靠，安裝簡(jiǎn)單，性價(jià)比高的特點(diǎn)。簡(jiǎn)單地說，當(dāng)粉末倉(cāng)中的材料位置低于設(shè)定的下限或負(fù)荷高于設(shè)定的上限時(shí)，將發(fā)出警報(bào)信號(hào)以提示操作者執(zhí)行相應(yīng)的處理。

The liquid level meter of cement silo of automatic mixer mostly adopts switch type liquid level meter, which is installed at the bottom of cement silo. It has the characteristics of reasonable structure, reliable performance, simple installation and high cost performance. In short, when the material position in the powder bin is lower than the set lower limit or the load is higher than the set upper limit, an alarm signal will be issued to prompt the operator to carry out the corresponding processing.

水泥倉(cāng)液位計(jì)的工作原理如下：

The working principle of liquid level gauge in cement silo is as follows:

AC微電機(jī)在減速后驅(qū)動(dòng)葉片旋轉(zhuǎn)或振蕩。當(dāng)檢測(cè)到的材料上升到葉片的位置時(shí)，葉片作用被阻擋，并且檢測(cè)機(jī)構(gòu)的主軸產(chǎn)生旋轉(zhuǎn)位移。該位移產(chǎn)生微動(dòng)開關(guān)動(dòng)作，輸出切換信號(hào)，然后另一個(gè)微動(dòng)開關(guān)操作以切斷電動(dòng)機(jī)的電源以停止操作。只要倉(cāng)庫(kù)中的物料級(jí)別保持不變，此狀態(tài)將繼續(xù)。

The AC micromotor drives the blades to rotate or oscillate after deceleration. When the detected material rises to the position of the blade, the effect of the blade is blocked, and the spindle of the detection mechanism generates rotation displacement. The displacement first generates a micro switch action, outputs a switching signal, and then another micro switch operates to cut off the power supply of the motor to stop the operation. This status will continue as long as the item level in the warehouse remains unchanged.

當(dāng)材料降低時(shí)，葉片阻力消失，測(cè)量裝置通過彈簧的張力返回到原始狀態(tài)，并且控制電動(dòng)機(jī)電源的微動(dòng)開關(guān)以打開電動(dòng)機(jī)并旋轉(zhuǎn)。隨后，另一個(gè)微動(dòng)開關(guān)操作以輸出切換信號(hào)，只要沒有材料阻擋檢測(cè)葉片的旋轉(zhuǎn)，該切換信號(hào)將保持不變。彈簧的張力可以根據(jù)不同比重的材料進(jìn)行調(diào)節(jié)。當(dāng)比率大時(shí)，彈簧的張力可以非常強(qiáng)烈地調(diào)節(jié)，反之亦然。

When the material is reduced, the blade resistance disappears, the measuring device returns to the original state through the spring tension, and controls the micro switch of the motor power supply to turn on the motor and rotate. Then, another micro switch operates to output a switching signal, which will remain unchanged as long as there is no material blocking the rotation of the detection blade. The tension of the spring can be adjusted according to the material with different specific gravity. When the ratio is large, the spring tension can be adjusted very strongly, and vice versa.
