大街上的混凝土搅拌车为什么要边走边转动?
来源:https://www.cnzkjf.com/ 日期:2020-06-13
  大家好,欢迎收看中科搅拌机。我们都见过混凝土搅拌机,即使是在大马路上,它也会不停地转动罐子来搅拌水泥,这时候我们就会疑惑了,这种长时间工作,对不会损伤车子吗?还是说老板在车上装了摄像头,司机师傅不得不努力工作呢?
  Hello, everyone. Welcome to Zhongke mixer. We've all seen concrete mixers. Even on the road, they always rotate the cans to mix the cement. At this time, we'll wonder if this kind of long-time work will not damage the car? Or does the boss install a camera in the car and the driver has to work hard?
  作为一种运送或者搅拌建筑用混凝土的专用卡车,混凝土搅拌车无疑给建筑工人们省了许多事。只需要将水泥、水、砂石等建筑材料放到搅拌罐中,在搅拌装置的作用下,搅拌罐正转,混凝土沿罐子内部的螺旋叶片向里运动将材料混合均匀,然后再反转搅拌罐,混凝土便沿着叶片向外卸出。
  As a kind of special truck for transporting or mixing construction concrete, concrete mixer undoubtedly saves many things for construction workers. Just put the cement, water, sand and other building materials into the mixing tank. Under the action of the mixing device, the mixing tank is rotating forward, and the concrete moves inward along the spiral blade inside the tank to mix the materials evenly, and then reverse the mixing tank, and the concrete is discharged outward along the blade.

  然而干过工程的人都知道,混凝土一旦长时间静止,就很容易固化成块,当周围有东西时,会牢牢地黏在上面,一旦干了之后,很难去除,因此即使是运送已经搅拌好的混凝土,搅拌车也会不停地转动,以防止混凝土粘在搅拌罐内占用空间,减少搅拌罐的容积。而在使用搅拌车运送混凝土的时候,搅拌罐也会采用回转密封技术,将搅拌车的进出料口牢牢密封住,减少水份蒸发,从而进一步水泥固化的问题。
  However, people who have worked on the project know that once the concrete is stationary for a long time, it is easy to solidify into a block. When there is something around, it will be firmly stuck on it. Once it is dry, it is difficult to remove it. Therefore, even when transporting the already mixed concrete, the mixer will rotate constantly to prevent the concrete from sticking in the mixing tank and occupying space, reducing the volume of the mixing tank. When the mixer is used to transport concrete, the mixing tank will also adopt the rotary sealing technology to firmly seal the inlet and outlet of the mixer, reduce the evaporation of water, so as to further solve the problem of cement solidification.
  同时,为了延长搅拌车的寿命,在每次装料前,都需要用水冲洗进料口,使进料口在装料时保持湿润。到工地卸料后,人们还需要对出料槽以及搅拌罐记性清洗,一般的方法是往内加清洗用水,然后在车辆回程时,保持混凝土搅拌罐慢速转动。当然有时也会在运输途中进行干料搅拌以清洗系统。
  At the same time, in order to extend the service life of the mixer, before each loading, it is necessary to wash the feed port with water to keep the feed port wet during loading. After unloading at the construction site, people also need to clean the discharge tank and mixing tank in memory. The general method is to add cleaning water inside, and then keep the concrete mixing tank rotating slowly when the vehicle returns. Of course, there are also times when dry materials are mixed during transportation to clean the system.
