水泥自动搅拌车为什么会出现粘灌现象？经过实践和分析，我们认为水泥自动搅拌车粘罐原因可以分为两大类：即设计不合理和使用不当，主要有以下几种形式：

Why does the cement automatic mixer stick? Through practice and analysis, we believe that the causes of tank sticking of automatic cement mixer can be divided into two categories: unreasonable design and improper use, mainly in the following forms:

（1）卸料残余率和叶片设计的不合理。

(1) Discharge residual rate and blade design are unreasonable.

从搅拌筒的内部结构看，水泥自动搅拌车的拌筒是依靠回转的筒体带动其中的两条螺旋叶片所产生的螺旋运动，使混凝土获得既有“切向”又有“轴向”的复合运动，从而使搅拌筒具有搅拌和卸料的功能，因此形成这一螺旋运动的有关因素，诸如螺旋叶片的曲线参数，搅拌筒的几何形状和尺寸等对搅拌车的卸料残余率都有重要影响。

From the perspective of the internal structure of the mixing drum, the mixing drum of the cement automatic mixer is driven by the rotating cylinder to produce the spiral movement of the two spiral blades, so that the concrete can obtain the composite movement of both "tangential" and "axial", so that the mixing drum has the functions of mixing and unloading. Therefore, the factors related to the formation of this spiral movement, such as the curve parameters of the spiral blades, The geometric shape and size of the mixing drum have an important influence on the discharge residual rate of the mixer truck.

而过大的卸料残余率意味着搅拌车在卸料结束后在水泥自动搅拌车里会有更多的余料，因而更有可能因日积月累在搅拌罐中粘料。目前大多数厂家采用的是等角对数螺旋线叶片，在卸料残余率上还有很大的改进空间。

However, excessive discharge residual rate means that there will be more residual materials in the cement automatic mixer truck after the completion of discharge, which is more likely to stick materials in the mixing tank due to accumulation over time. At present, most manufacturers use equiangular logarithmic spiral blades, and there is still much room for improvement in the discharge residual rate.

（2）水泥自动搅拌车工作环境温度过高。

(2) The working environment temperature of automatic cement mixer is too high.

夏季在南方地区白天中午前后，环境温度经常超过30℃，在这种情况下运输混凝土，将会由于混凝土坍落度损失快以及罐体周围温度相对更高，因而混凝土更容易粘罐。

In summer, around noon in the day in the south, the ambient temperature often exceeds 30 ℃. When transporting concrete in this case, the concrete will be easier to stick to the tank because of the rapid loss of concrete slump and the higher temperature around the tank relative to the center.

（3）运输距离过长。

(3) The transportation distance is too long.

随着城市化的进程及城市规划的要求，越来越多的搅拌站被要求迁到郊区和郊县，与市区的距离越来越远，而由于混凝土这一产品的特殊性，任何预拌混凝土在未添加缓凝剂的情况下，都在1h左右进入初凝状态。

With the process of urbanization and the requirements of urban planning, more and more mixing plants are required to be moved to the suburbs and suburban counties, which are more and more far away from the urban area. Due to the particularity of concrete, any ready mixed concrete will enter the initial setting state in about 1h without adding retarder.

如果这时才进行混凝土浇注施工，不但影响混凝土的工程质量，而且因混凝土失去流动性，易在搅拌筒及叶片上凝结，导致粘罐，严重时甚整车混凝土粘在罐内及造成液压设备的损坏，所以水泥自动搅拌车运送预拌混凝土有其时间控制的输送半径，一般应控制在1h以内。

If the concrete pouring construction is carried out at this time, it will not only affect the quality of the concrete project, but also because the concrete loses its fluidity, it is easy to condense on the mixing drum and blades, which will lead to tank sticking, even if the whole vehicle concrete sticks in the tank and causes damage to the hydraulic equipment. Therefore, the automatic cement mixer has its time controlled delivery radius for transporting ready mixed concrete, which should be controlled within 1h generally.

此外水泥自动搅拌车驾驶员在搅拌车卸料完毕后未及时清理清洗搅拌罐内及叶片上残留的混凝土，在搅拌车回站过程中不转动搅拌罐，残留的混凝土干燥后凝固在拌筒及叶片上，以后就会越聚越多，形成粘罐现象。更多相关内容就来我们网站http://www.sdzkjf.cn咨询吧！

In addition, the driver of the automatic cement mixer failed to clean and clean the residual concrete in the mixing tank and on the blades in time after the unloading of the mixer truck, did not rotate the mixing tank when the mixer truck returned to the station, and the residual concrete dried and solidified on the mixing tank and blades, which will accumulate more and more in the future, forming the phenomenon of tank sticking.
