近期有不少车友在咨询关于混凝土搅拌机搅拌筒的相关知识,小编在查阅资料时发现,这学问可大了,今天,就为大家详细详解一下混凝土搅拌机搅拌筒的构成以及工作原理。
Recently, many motorists have been consulting about the mixing cylinder of the concrete mixer. Xiao Bian found that this knowledge is great when looking up materials. Today, I will explain the composition and working principle of the mixing cylinder of the concrete mixer in detail.
混凝土搅拌机搅拌筒一般由前锥、中间筒和后锥三段组成。筒内有两条间隔180°的,对称焊接在筒壁上的螺旋叶片,这两条螺旋线与筒壁形成了螺旋通道,混凝土就沿着这些螺旋通道完成进料、搅拌和卸料等工作。一般前锥、后锥分别采用相同等升角的圆锥对数螺旋片,中间筒一般是圆柱体,一般采用不同等升角的圆柱螺旋叶片。
The mixing cylinder of concrete mixer is generally composed of three sections: front cone, middle cylinder and rear cone. There are two spiral blades symmetrically welded on the cylinder wall with an interval of 180 ° in the cylinder. These two spiral lines form spiral channels with the cylinder wall, along which concrete can complete feeding, mixing and unloading. Generally, the front cone and the rear cone adopt the cone logarithmic spiral slice with the same equal lift angle respectively, the middle cylinder is generally a cylinder, and the cylindrical spiral blades with different equal lift angles are generally used.
混凝土搅拌机的搅拌筒是依靠回转的筒体带动两条螺旋叶片对混凝土进行搅拌和卸料作业的。工作时,搅拌筒绕其轴线转动,使得混凝土沿搅拌叶片的螺旋线运动,螺旋曲线促使混凝土沿相反的方向移到末端和顶层,这是混凝土搅拌时的主要运动。
The mixing cylinder of the concrete mixer is used to mix and unload concrete by driving two spiral blades with the rotary cylinder. When working, the mixing cylinder rotates around its axis, making the concrete move along the spiral line of the mixing blade. The spiral curve makes the concrete move to the end and top layer in the opposite direction, which is the main movement of concrete mixing.
同时,由于混凝土与筒壁和叶片的摩擦力及其内在的附着力作用,所以在筒体转动过程中,混凝土达到一定高度后,必在其自重作用下,克服上述摩擦力和内聚力而向下翻跌和滑移。其次在叶片的底部,由于叶片的形状是曲线型,故混凝土在外力的作用下产生旋转式的搅动。
At the same time, due to the friction between concrete and cylinder wall and blade and its internal adhesion, when the cylinder rotates, the concrete reaches a certain height, under its own weight, it must overcome the above friction and cohesion and fall down and slip. Secondly, at the bottom of the blade, because the shape of the blade is curved, the concrete will produce rotary agitation under the action of external forces.
混凝土搅拌机
由于搅拌筒在连续转动,所以混凝土所做的是3种运动混合一起的复合运动,即三维搅拌运动。从而使混凝土被均匀的搅拌,保证其匀质性。
Because the mixing cylinder is rotating continuously, the concrete is doing a composite movement of three movements, namely three-dimensional mixing movement. So that the concrete can be evenly mixed to ensure its homogeneity.
搅拌筒结构应简单,紧凑,轻便,以尽量降低上车自重,这有利于提高混凝土搅拌机的有效装载容量和相对减少上车的功率消耗。同时,结构的布置要适应底盘的狭长体形和高度限制,应尽量降低搅拌筒和混凝土搅拌机的整车高度和重心,以保证混凝土搅拌机的行使稳定性和通过性,还应有足够的有效装载容积,满足规定的搅拌和装、卸料性能,在结构上适应运载底盘和搅拌工作的特点等要求。
The mixing drum shall be simple, compact and light in structure to minimize the deadweight of the truck, which is conducive to improving the effective loading capacity of the concrete mixer and relatively reducing the power consumption of the truck. At the same time, the layout of the structure should adapt to the narrow and long shape of the chassis and height restrictions. The height and center of gravity of the mixing drum and concrete mixer should be reduced as much as possible to ensure the running stability and trafficability of the concrete mixer. It should also have sufficient effective loading capacity to meet the specified mixing, loading and unloading performance, and structurally adapt to the characteristics of the transport chassis and mixing work.
搅拌筒的外形比较复杂,沿轴线方向的断面直径是变化的。中部直径大,两边逐渐收缩。大容量的搅拌筒则在两段截锥体间加一段圆柱体,以扩大装载容积,同时避免搅拌筒中部尺寸过大。更多相关内容就来我们网站http://www.zkhntjbc.com进行咨询了解吧!
The shape of the mixing drum is relatively complex, and the section diameter along the axis direction is variable. The middle diameter is large, and the two sides gradually shrink. For the large capacity mixing cylinder, a section of cylinder is added between the two truncated cones to expand the loading capacity and avoid excessive size in the middle of the mixing cylinder.
