（1）喂料裝置的設(shè)計不合理。 如果水泥和粉煤灰進(jìn)料口的位置和方向不合理，則大部分粉末放在軸上，這樣粘接在軸上形成“抱抱”現(xiàn)象;

(1) The design of feeding device is unreasonable. If the position and direction of cement and fly ash inlet are not reasonable, most of the powder will be put on the shaft, which will form "hugging" phenomenon;

（2）沖洗點和沖洗方向的位置不正確，或沖洗壓力太低。 當(dāng)沖洗水箱時，粘附在攪拌裝置上的混凝土不會被沖洗掉，形成“擁抱”現(xiàn)象;

(2) The position of flushing point and direction is incorrect, or the flushing pressure is too low. When the water tank is flushed, the concrete adhered to the mixing device will not be washed away, forming a "hug" phenomenon;

（3）攪拌筒的體積利用率不合理，體積利用率太小，攪拌軸暴露在混凝土上，一部分附著在上部的混凝土不會攪拌， 在軸上凝固形成“抱軸”現(xiàn)象。

(3) The volume utilization ratio of the mixing drum is unreasonable, the volume utilization ratio is too small, the mixing shaft is exposed on the concrete, part of the concrete attached to the upper part will not be stirred, and the phenomenon of "holding shaft" is formed on the shaft.

（4）靠近攪拌軸的攪拌臂的速度太低。

(4) The speed of the mixing arm near the mixing shaft is too low.
            

攪拌機(jī)主機(jī)“保持軸”的方案：

The solution of mixer host "holding shaft"

（1）在進(jìn)料裝置的設(shè)計中，水泥和粉煤灰進(jìn)料口位置位于兩個攪拌軸之間，切割角度沿攪拌器的軸向。

(1) In the design of the feeding device, the cement and fly ash feeding port is located between the two mixing shafts, and the cutting angle is along the axial direction of the mixer.

（2）在混合機(jī)的制造過程中，應(yīng)確保噴水裝置的安裝焊接位置，以達(dá)到?jīng)_洗點的正確位置和沖洗方向。 在攪拌裝置的供水系統(tǒng)的設(shè)計過程中，確保沖洗的分壓的可靠性。 可以增加用于沖洗的特殊壓力泵或使用高水箱;

(2) In the manufacturing process of the mixer, the installation and welding position of the sprinkler should be ensured to achieve the correct position and direction of the flushing point. In the design process of water supply system of mixing device, the reliability of partial pressure of flushing is ensured. Special pressure pump for flushing or high water tank can be added;

（3）設(shè)備卸載和卸載后，設(shè)備操作人員應(yīng)及時清洗并沖洗油箱，以確保拆除粘附的混凝土。 設(shè)備操作人員應(yīng)定期檢查計量系統(tǒng)中計量料斗的連接和關(guān)閉緊度，注意是否有泄漏，如果是，請及時。

(3) After the equipment is unloaded and unloaded, the equipment operator shall clean and flush the oil tank in time to ensure the removal of the adhered concrete. Equipment operators should regularly check the connection and closing tightness of the metering hopper in the metering system, and pay attention to whether there is leakage. If so, please remove it in time.
