Unpowered automatic impurity-removing device for river sand mining equipment

Abstract

The invention discloses a non-powered automatic impurity removal device for river sand mining equipment, which comprises a first impurity removal box, a second impurity removal box, a conical net cover, an inclined material guide plate, an iron impurity recovery device, an inner cylinder, arc-shaped net, rotating cylinder, propeller impeller, fixed cylinder and pressure relief valve, the upper side of the first miscellaneous removal box is fixedly connected with an inclined material guide plate in the shape of left lower and right higher; pebbles, water plants , plastic bags, branches and other sundries are blocked by the conical net cover, and move down to the inclined material guide plate, and the sundries move down and are discharged into the square tube through the miscellaneous discharge pipe, and the sundries fall out after passing through the square tube. The iron impurities are adsorbed on the magnet rod, which facilitates the recovery of iron impurities. The sand and water in the rotating cylinder are discharged through the sand outlet pipe, realizing the effect of two times of impurity removal without power, and when the water in the inner cylinder flows downward , it will make the propeller impeller rotate, then drive the rotating cylinder to rotate, which is convenient for the suction cylinder to rotate and absorb sand.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a non-powered automatic impurity removal device for river sand mining equipment. Background technique [0002] Only a simple mesh fence is used in river sand mining to intercept pebbles and other impurities mixed in river sand. Production practice has proved that when the water column rushes to the fence, only the pebbles will be effectively blocked and dropped due to their small size and heavy weight, while the lighter impurities such as aquatic plants, plastic bags, and branches contained in the water column will be blocked by the water column. The impact force firmly hits the fence and cannot fall, and manual cleaning is required from time to time, which affects work efficiency. In addition, in the filtration of sand and gravel, the filter screen needs to be cleaned regularly, which consumes manpower and material resources. Contents of the invention [0003] The ob...
