攪拌機是一種用于運輸混凝土施工的專用運輸車。如果出現(xiàn)問題，將嚴重影響工程進度。為了更好的使用攪拌機，我們下面來介紹一下攪拌機的一個常見問題：當混凝土在攪拌槽中凝結(jié)時，我們該怎么辦呢？

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。混凝土在攪拌槽中凝結(jié)的原因很多。主要原因是攪拌機啟動器不能工作，液壓機沒有動力輸入，導致液壓機停止工作，使上料罐不能轉(zhuǎn)動，混凝土在攪拌機罐內(nèi)凝結(jié)。用氣槍打碎凝固的混凝土，然后把它鏟出來一點！

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!

油箱的下部需要開一個口，打開一個原來用螺絲擰緊的蓋子。此罩用于工作時打開空氣，緊急情況下卸料。裝罐過程中，罐內(nèi)要有人通風，在加料罐入口處放置風機吹入，同時安裝氣槍。

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.

工作時要撿灰，接水管濕潤破碎的混凝土。將混凝土攪拌機的攪拌罐內(nèi)混凝土打碎鏟出后，可將部分切斷，焊接，封蓋，灌滿水測試是否能正常轉(zhuǎn)動，再加入少量材料，觀察液壓機是否能正常工作。如果沒有問題，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鈣、硅酸三鈣。理論上講，鹽酸可以與之反應(yīng)解除其固態(tài)形狀。由于攪拌機的料口很小，鹽酸量難以控制，且鹽酸也可以與攪拌機罐體發(fā)生反應(yīng)，所以操作很難實現(xiàn)。實踐中一旦出現(xiàn)這種情況，往往需要用電焊或氣割切開罐體，然后將凝固的混凝土機械破碎。

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.

事實上，這些措施并沒有像往常一樣做好保護工作。在正常的運輸過程中，司機必須保持油箱的運轉(zhuǎn)，以確?；炷敛粫??；炷两桓逗?，攪拌筒內(nèi)部通常用水沖洗，以防止殘余混凝土硬化。通常經(jīng)常修理小車，以保證攪拌機的發(fā)動機能隨時正常運轉(zhuǎn)，從而保證液壓機有足夠的動力來攪拌混凝土。

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.
