Description
Technical Field
[0001] The utility model relates to the technical field of sand and gravel slurry water collection, in particular to a sand and gravel slurry water collection device for belt transport in a concrete mixing station. Background Art
[0002] The sand and gravel separator is a device that can effectively separate sand and gravel mixtures containing mud and sand. The finished products are usually crushed stone and mud and sand. Cement slurry water continuously flows out from the slurry outlet at the bottom of the separator and flows into the slurry pool through the slurry guide trough. The cleaned sand and gravel are pushed by the spiral blades in the mixing separator. After the sand and stone are separated, they fall into the material pool through their respective outlets.
[0003] At present, when sand and gravel on the belt conveyor are recovered and cleaned, the outer wall of the belt conveyor is generally cleaned by spraying water, and the sand and gravel adhering to the outer wall of the belt conveyor is mixed with water and discharged into the interior of the collection sedimentation tank. However, after the belt conveyor is cleaned by water on its outer wall, there will be a certain amount of water stains adhering to the outer wall of the belt conveyor. When the sand and gravel come into contact with water, the adhesion between the belt conveyor and the sand and gravel is improved, resulting in an increase in the amount of sand and gravel adhering to the outer wall of the belt conveyor. These sand and gravel will enter the interior of the collection sedimentation tank after being cleaned by the spray head, which not only reduces the efficiency of sand and gravel transportation, but also increases the storage capacity inside the collection sedimentation tank, and increases the workload of subsequent separation of sand and gravel and water. Therefore, a concrete mixing station belt conveyor sand and gravel slurry water collection device is proposed. Utility Model Content
