Abstract

The invention discloses a method and a device for cleaning sand gravel. The method for cleaning the sand gravel comprises the following steps of: allowing fine aggregate which is fed by primary sieving conveying equipment (6) to fall into a mortar mixer (1), injecting clean water from a water filling nozzle (4), rotating a stirring arm (2) under the drive of a drive motor (3) to stir and extrude the fine aggregate in water, and fully wetting and dissolving soil adhered to the sand gravel in water; and extruding from a discharge hole (5) when the fine aggregate is stacked to the height of the discharge hole (5), and allowing the fine aggregate to fall onto secondary sieving conveying equipment, and sieving and washing. In the device for cleaning the sand gravel, the primary sieving conveying equipment (6) is arranged above the left side of the mortar mixer (1), the water filling nozzle (4) is formed above the right side of the mortar mixer (1), the discharge hole (5) is formed on the right side of a machine body of the mortar mixer (1) and above the stirring arm (2), and the secondary sieving conveying equipment (7) is arranged below the discharge hole (5).

Description

technical field [0001] The invention relates to a sand and gravel cleaning method and a cleaning device. Background technique [0002] Most of the sand and gravel used in the construction and crushing process is mountain gravel, which is directly excavated from the mountain and transported to the construction site. It is crushed and classified by crushing equipment to meet the construction and production requirements. The mountain gravel has a large mud content, generally between 20% and 30%, which is far greater than the design value of 3%, so the mud content must be reduced during gravel processing. However, it is difficult for traditional crushing equipment to wash the soil clean during processing, which cannot meet the requirements of construction and production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sand and gravel cleaning method and a cleaning device, so as to overcome the shortcomings in the ...
