How Is The Sand Washing Machine Cleaned
In highway engineering, a large amount of crushed stone material is required as the aggregate of asphalt mixture, and its content exceeds 80%. In addition to a certain gradation, various crushed stones should also be dehydrated, deslimed, and various debris removed. Especially when the stone is contaminated by soil, it will seriously affect its adhesion to asphalt, and then affect the quality and durability of the asphalt mixture and its pavement. When the sand washing machine is working, the power device drives the impeller to rotate slowly after deceleration by the V-belt, reducer, and gear. The sand and gravel enter the washing tank from the feeding trough, roll under the impeller, and grind each other to remove the covering sand and gravel surface. At the same time, it destroys the water vapor layer covering the sand grains to facilitate dehydration; at the same time, add water to form a strong water flow, timely take away impurities and foreign objects with small specific gravity, and discharge them from the overflow washing tank to complete the cleaning effect.
When the sand washer is cleaning, it can be divided into two parts, one is the cleaning outside the equipment, and the other is the cleaning in the sand washer tank.
When cleaning the outside of the sand washer, it is relatively simple. You can directly use the high-pressure faucet to rinse the outside of the tank. However, one thing to pay attention to in this process is to be careful not to splash water on the motor.
It is relatively troublesome when it is inside the tank of the sand washer. First of all, we can still use a high-pressure faucet for direct flushing, but because a large amount of slag dirt may accumulate in the sand washer tank during operation, sometimes just washing with clean water cannot effectively remove residual dirt. At this time, we It is necessary to use pickling or alkaline washing methods.
It has the advantages of large production processing capacity and less sand powder loss. The processing capacity of the sand washing machine required by different users in actual production is different. In order to meet the needs of different users, manufacturers need to focus on producing some different specifications and models. Sand Washing Machine.
