搅拌车:那么为何宁愿倒掉也不能闷罐呢?

作者:http://www.zkzsljbc.com 时间:2021-11-30

因为混凝土是由石头,砂子,水泥和水组成,如果运输过程中不转,并且不停的颠簸,石头就会下沉到最底下,砂子在中间,水泥和水在最上面,等运输到目的地就会出现结块的现象,也是我们常说的闷罐。
Because concrete is composed of stone, sand, cement and water, if it doesn't rotate and bumps constantly during transportation, the stone will sink to the bottom, the sand is in the middle, and the cement and water are on the top. When it is transported to the destination, there will be caking, which is also what we often call a stuffy tank.
因此,转动既可以防止混凝土凝固,又可防止混凝土分层,而且还可以让混凝土混合的更均匀。
Therefore, rotation can not only prevent concrete solidification, but also prevent concrete stratification, but also make concrete mix more evenly.

相信很多小伙伴都看到过在路边倒混凝土,好奇的是这也太浪费了吧,这么一车混凝土就不要了吗?
I believe many friends have seen pouring concrete on the roadside. Curiously, it's too wasteful. Don't you want such a load of concrete?
混凝土搅拌车在运输过程中,有时候也会出现各种故障或者长时间堵车等情况,这就会让混凝土凝固在罐体中,出现闷罐现象。
During the transportation of concrete mixer truck, sometimes there will be various faults or traffic jam for a long time, which will make the concrete solidify in the tank and lead to tank stuffing.
出现这种情况后人们也想出了很多办法,有采用在罐体某个位置切一个洞,然后人工用风镐将里面的混凝土一点点的清理出来,最后再把开孔焊接封上。
After this situation occurred, people also came up with many methods, including cutting a hole at a certain position of the tank, manually cleaning out the concrete inside with an air pick, and finally welding and sealing the opening.
也有利用破壁机配合水钻打孔,这样能够减少粉尘和沙石飞溅,然后从出料口排出,这种方法效率也较高。
Some also use the wall breaking machine to cooperate with the water drill to drill holes, which can reduce the dust and sand splash, and then discharge it from the discharge port. This method is also more efficient.
还有就是利用热胀冷缩的方法,即便是罐内被堵住,但罐内还是会有空间,用油烧混凝土后迅速浇水冷却,混凝土会变脆,这样也更容易清理自上料搅拌车
There is also the method of thermal expansion and cold contraction. Even if the tank is blocked, there will still be space in the tank. After burning the concrete with oil, water it quickly for cooling, and the concrete will become brittle, which is easier to clean.
据说国外也有直接用火药来炸的,但是这是需要专业的人才能操作,而且风险也是很大的,当然了,最省事的办法就是直接换一个罐体。
It is said that foreign countries also directly use gunpowder to explode, but this requires professional people to operate, and the risk is also great. Of course, the easiest way is to directly change a tank.
清理闷罐的费用根据不同的地方和清理的方法,价格也都不一致,但是最低也要五千以上,有的地方则会达到2万,还有就是经过清理后的罐体或多或少都有损坏,使用寿命也将变短。
The cost of cleaning the stuffy tank varies according to different places and cleaning methods, but the minimum price is more than 5000, in some places it will reach 20000, and the cleaned tank will be damaged more or less, and the service life will be shorter.
混凝土搅拌车的结构

罐体外壳是由非常耐磨的钢材制成的,为了能够自动装卸混凝土,内部还焊有特殊形状的旋转叶片,转动时混泥土会随着叶片旋转的方向运动,在不断的旋转和翻动过程中让各种材料充分混合和搅拌。
The tank shell is made of very wear-resistant steel. In order to automatically load and unload the concrete, a rotating blade with special shape is welded inside. When rotating, the concrete will move with the direction of blade rotation, and various materials will be fully mixed and stirred in the process of continuous rotation and turnover.
在进料和运输过程中罐体正转,混凝土会随叶片向里运动,在出料过程中,罐体则会反转,混凝土沿着叶片向外将卸出。
In the process of feeding and transportation, the tank rotates forward, and the concrete will move inward with the blade. In the process of discharging, the tank will reverse, and the concrete will be discharged outward along the blade.
罐体的旋转则是靠着卡车上的液压驱动系统来完成的,通常都是通过卡车上的动力输出轴带动液压泵从而驱动搅拌罐体旋转的。
The rotation of the tank is completed by the hydraulic drive system on the truck. Usually, the hydraulic pump is driven by the power take-off shaft on the truck to drive the mixing tank to rotate.
我们经常能够在各种报道中看到关于混凝土搅拌车的各种交通事故,也造成了很多的伤亡,其主要有这些原因,混凝土搅拌车的整个底盘都非常的高,驾驶员在操作过程中就会出现很多的盲区,特别是转弯的时候。
We can often see various traffic accidents of concrete mixer truck in various reports, which also caused a lot of casualties. These are the main reasons. The whole chassis of concrete mixer truck is very high, and the driver will have a lot of blind spots during operation, especially when turning.
还有就是混凝土搅拌车的速度都普遍较快,加上车身和载有很重的混凝土,制动距离就会变长等,都是造成事故多发的原因。
In addition, the speed of concrete mixer truck is generally fast. In addition, the braking distance will become longer due to the body and heavy concrete, which are the reasons for frequent accidents.
