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?
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!
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.
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.
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.
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.
