工作原理

　　Working Principle

　　螺旋洗砂機工作時，電機通過三角帶、減速機、齒輪減速后帶動葉輪緩慢轉動，砂石由給料槽進入洗槽中，在葉輪帶動下翻滾，并互相研磨，除去覆蓋砂石表面的雜質，同時破壞包覆砂粒的水汽層，以利于脫水;同時加水，形成強大水流，及時將雜質及比重小的異物帶走，并從溢出口洗槽排出，完成清洗作用。干凈的砂石由葉片帶走，砂石從旋轉地葉輪倒入出料槽，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.

　　性能特點

　　Performance Characteristics

　　1、該洗砂機結構簡單，性能穩定，葉輪傳動軸承裝置與水和受水物料隔離，大大避免了軸承因浸水、砂和污染物導致損壞的現象發生。

　　2、該類洗砂機用于砂石場洗砂時與傳統的螺旋洗砂機相比有明顯優勢如下：

　　<1>中細砂和石粉流失極少，所洗建筑砂級配合細度模數達到《建筑用砂》、《建筑用卵石、碎石》標準。

　　<2>該機除篩網外幾乎無易損件。

　　<3>使用壽命長，長期不用維修。 洗砂機具有洗凈度高，結構合理，處理量大，功耗小，洗砂過程中砂子流失少，尤其是洗砂機傳動部分均與水、砂隔離，故其故障率大大低于目前常用的洗砂機，是國內洗砂行業升級換代的合適選擇。

　　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.
