工作原理

　　Working Principle

　　螺旋洗砂机工作时，电机通过三角带、减速机、齿轮减速后带动叶轮缓慢转动，砂石由给料槽进入洗槽中，在叶轮带动下翻滚，并互相研磨，除去覆盖砂石表面的杂质，同时破坏包覆砂粒的水汽层，以利于脱水;同时加水，形成强大水流，及时将杂质及比重小的异物带走，并从溢出口洗槽排出，完成清洗作用。干净的砂石由叶片带走，砂石从旋转地叶轮倒入出料槽，完成砂石的清洗作用。

　　When the spiral sａnd washing machine is working, the motor drives the impeller to rotate slowly after decelerating through the triangle belt, reducer and gear. The sａnd enters the washing tank from the feeding tank, rolls under the driving of the impeller, and grinds with each other to remove the impurities covering the surface of the sａnd and destroy the water vapor layer covering the sand, so as to facilitate dehydration. At the same time, add water to form a strong water flow, and timely change the impurities and small specific gravity The material is taken away and discharged from the overflow outlet washing tank to complete the cleaning function. The clean sａnd is taken away by the blade, and finally the sａnd is poured into the discharge chute from the rotating impeller to complete the cleaning function of the sand.

　　性能特点

　　Performance Characteristics

　　1、该洗砂机结构简单，性能稳定，叶轮传动轴承装置与水和受水物料隔离，大大避免了轴承因浸水、砂和污染物导致损坏的现象发生。

　　2、该类洗砂机用于砂石场洗砂时与传统的螺旋洗砂机相比有明显优势如下：

　　<1>中细砂和石粉流失极少，所洗建筑砂级配合细度模数达到《建筑用砂》、《建筑用卵石、碎石》标准。

　　<2>该机除筛网外几乎无易损件。

　　<3>使用寿命长，长期不用维修。 洗砂机具有洗净度高，结构合理，处理量大，功耗小，洗砂过程中砂子流失少，尤其是洗砂机传动部分均与水、砂隔离，故其故障率大大低于目前常用的洗砂机，是国内洗砂行业升级换代的合适选择。

　　1. The structure of the sａnd washing machine is simple and the performance is stable. The impeller drive bearing device is isolated from water and water receiving materials, which greatly avoids the damage of bearings caused by water immersion, sａnd and pollutants.

　　2. Compared with the traditional spiral sａnd washing machine, this kind of sａnd washing machine has the following advantages when it is used for sａnd washing in sａnd and stone field:

　　<1> The loss of medium and fine sａnd and stone powder is very little, and the fineness modulus of the washed construction sａnd grade meets the national standards of "construction sand", "construction pebble, gravel".

　　<2> There are almost no wearing parts except screen.

　　<3> Long service life, no maintenance for a long time. The sａnd washing machine has the advantages of high cleaning degree, reasonable structure, large processing capacity, small power consumption, less sａnd loss in the process of sａnd washing, especially the transmission part of the sａnd washing machine is isolated from water and sand, so its failure rate is much lower than that of the commonly used sａnd washing machine, which is a suitable choice for upgrading the domestic sａnd washing industry.
