Description

High-efficiency slurry filtering device for quartz sand washing Technical Field The utility model relates to the technical field of quartz sand processing, in particular to a high-efficiency slurry filtering device for quartz sand washing. Background Quartz sand has a variety of uses, one of which is useful as a fracturing propping agent for petroleum. When quartz sand is used as a fracturing propping agent for petroleum, strict requirements are imposed on the particle size. Therefore, the quartz sand requires water washing and screening classification. During screening, quartz sand with different mesh numbers is obtained by flushing with water and passing through screens with different apertures. In the screening process, quartz sand and mud with different meshes also enter water flow to form mud mortar. And after the mud mortar is treated, the quartz sand in the mud mortar can be recovered. The remaining slurry is rich in clay and cannot be filtered through a screen. The slurry is generally treated by natural sedimentation, but the natural sedimentation time is longer on the one hand, and clay accumulated at the bottom is difficult to clean on the other hand. Disclosure of utility model In view of the above, it is necessary to provide a high-efficiency slurry filtering device for quartz sand washing that rapidly separates clay in slurry. The utility model provides a quartz sand washes sand and uses high-efficient mud filter equipment, includes drainage pipeline, filter bed, high-pressure spraying mechanism, the drainage pipeline is used for carrying mud, and the play thick liquid mouth of drainage pipeline is located the filter bed directly over to spread the mud on the filter bed, high-pressure spraying mechanism is located the below of filter bed, in order to wash the filter bed, the filter bed includes the fixed bolster, goes up backing roll, guide roll, lower back-up roll, filter cloth, the both sides of going up the backing roll are connected with the upper end of fixed bolster, the both sides and the end-to-end connection of fixed bolster of guide roll, and the both sides and the lower extreme of fixed bolster of lower back-up roll are connected, and the filter cloth encircles and goes up backing roll, guide roll, lower back-up roll setting and can rotate. Preferably, the high-pressure spraying mechanism comprises a supporting plate, a spraying pipeline and a plurality of spray heads, wherein the upper end of the supporting plate is connected with a fixed support, the two ends of the spraying pipeline are erected on the supporting plate, the spray heads are uniformly distributed on the spraying pipeline, and the spray heads are opposite to the filter cloth on the lower layer so as to wash the filter cloth. Preferably, the filter bed further comprises a tensioning mechanism, the tensioning mechanism comprises a tensioning support, an air cylinder, a movable support and a tensioning roller, the lower end of the tensioning support is connected with the fixed support, the fixed end of the air cylinder is connected with the tensioning support, the telescopic end of the air cylinder is connected with the movable support to drive the movable support to move, the movable support is clamped with the fixed support, and two sides of the tensioning roller are fixedly connected with the movable support to drive the movable support to move. Preferably, the high-efficiency slurry filtering device for quartz sand washing further comprises a scraping plate, wherein the scraping plate is arranged at the tail end of the filter bed and is tangential to the guide roller so as to separate clay on the filter bed.
