搅拌机是一种用于运输混凝土施工的专用运输车。如果出现问题，将严重影响工程进度。为了更好的使用搅拌机，我们下面来介绍一下搅拌机的一个常见问题：当混凝土在搅拌槽中凝结时，我们该怎么办呢？

Mixer is a special transport vehicle used for transporting concrete construction. If any problem occurs, it will seriously affect the project progress. In order to better use the mixer, let's introduce a common problem of the mixer: what should we do when the concrete coagulates in the mixing tank?

找出原因。混凝土在搅拌槽中凝结的原因很多。主要原因是搅拌机启动器不能工作，液压机没有动力输入，导致液压机停止工作，使上料罐不能转动，混凝土在搅拌机罐内凝结。用气枪打碎凝固的混凝土，然后把它铲出来一点！

Find out why. There are many reasons for concrete setting in the mixing tank. The main reason is that the mixer starter can not work, and the hydraulic press has no power input, resulting in the hydraulic press stopping working, so that the feeding tank can not rotate, and the concrete coagulates in the mixer tank. Use an air gun to break the solidified concrete, and then shovel it out a little!

油箱的下部需要开一个口，打开一个原来用螺丝拧紧的盖子。此罩用于工作时打开空气，紧急情况下卸料。装罐过程中，罐内要有人通风，在加料罐入口处放置风机吹入，同时安装气枪。

A hole shall be opened at the lower part of the oil tank to open a cover that was previously screwed down. This cover is used to open the air during operation and discharge materials in case of emergency. In the process of tank filling, there shall be ventilation in the tank. A fan shall be placed at the inlet of the charging tank to blow in, and an air gun shall be installed at the same time.

工作时要捡灰，接水管湿润破碎的混凝土。将混凝土搅拌机的搅拌罐内混凝土打碎铲出后，可将部分切断，焊接，封盖，灌满水测试是否能正常转动，再加入少量材料，观察液压机是否能正常工作。如果没有问题，你可以照常操作。

Ash shall be collected during work, and the water pipe shall be connected to wet the broken concrete. After the concrete in the mixing tank of the concrete mixer is broken and shoveled out, some parts can be cut off, welded, capped, filled with water to test whether it can rotate normally, and then a small amount of materials are added to observe whether the hydraulic press can work normally. If there is no problem, you can proceed as usual.

混凝土凝固后，其主要成分是硅酸二钙、硅酸三钙。理论上讲，盐酸可以与之反应解除其固态形状。由于搅拌机的料口很小，盐酸量难以控制，且盐酸也可以与搅拌机罐体发生反应，所以操作很难实现。实践中一旦出现这种情况，往往需要用电焊或气割切开罐体，然后将凝固的混凝土机械破碎。

After the concrete is solidified, its main components are dicalcium silicate and tricalcium silicate. Theoretically, hydrochloric acid can react with it to remove its solid state shape. Since the feed port of the mixer is very small, it is difficult to control the amount of hydrochloric acid, and hydrochloric acid can also react with the tank of the mixer, so the operation is difficult to achieve. Once this happens in practice, it is often necessary to cut the tank body with electric welding or gas cutting, and then mechanically break the solidified concrete.

事实上，解决这些措施并没有像往常一样做好保护工作。在正常的运输过程中，司机必须保持油箱的运转，以确保混凝土不会凝固。混凝土交付后，搅拌筒内部通常用水冲洗，以防止残余混凝土硬化。通常经常修理小车，以保证搅拌机的发动机能随时正常运转，从而保证液压机有足够的动力来搅拌混凝土。

In fact, these measures have not done a good job of protection as usual. During normal transportation, the driver must keep the oil tank running to ensure that the concrete will not set. After the concrete is delivered, the inside of the mixing drum is usually washed with water to prevent the residual concrete from hardening. The trolley is usually repaired frequently to ensure that the mixer engine can run normally at any time, so as to ensure that the hydraulic press has enough power to mix concrete.
