Description

Spiral propelling type multistage countercurrent ore washing and sorting machine Technical Field The invention relates to the technical field of mineral aggregate processing, in particular to a spiral propelling type multistage countercurrent ore washing and sorting machine. Background The spiral propelling multistage countercurrent washing and sorting machine is one kind of efficient mineral treating equipment based on countercurrent washing principle. The device mechanically advances the material by the internal rotating helical blade and forms countercurrent contact with clean washing water introduced from the discharge end, thereby realizing the crushing, desliming and primary separation of ores in continuous operation. The multistage design strengthens the cleaning efficiency, and is particularly suitable for treating placer ores or weathered ores with high mud content and high viscosity. However, the device has obvious technical pain points in the actual operation process that the spiral pushing rod can mutually squeeze and rub when the mineral blocks move along with the rising of the spiral blades in the process of pushing the mineral blocks, so that fine crushed aggregates can be peeled off from the surfaces of the mineral blocks, and small particle crushed aggregates can be entrained in mineral aggregates entering the mineral washing groove. Because a fixed gap exists between the spiral push rod and the inner wall of the ore washing tank, under the scouring action of strong water flow, the crushed aggregates and the washed sediment can be gradually deposited at the bottom of the ore washing tank. Along with the extension of the running time, the deposited crushed aggregates and sediment accumulation amount is continuously increased, on one hand, the rotation resistance of the spiral push rod is obviously increased, equipment jam and even stalling can be caused when the rotation resistance is serious, the production continuity is directly affected, and on the other hand, the turbidity of a water source at the feeding end of the ore washing tank is rapidly increased due to the mixing of the crushed aggregates and sediment, so that the washing effect of water flow on ores in the area is greatly attenuated. In order to compensate the reduction of the flushing effect of the feeding end, operators often need to additionally increase the injection amount of fresh water to try to maintain the ore washing effect by improving the water flow intensity, the operation directly leads to abnormal increase of water resource consumption, the production operation cost is improved, the treatment load of a rear-end water treatment system is greatly increased, the economical efficiency and the environmental protection of the whole set of mineral treatment process are reduced, and the operation efficiency and the application and popularization of the equipment are limited. Disclosure of Invention In view of the problem that the fine crushed aggregates flow downwards along with water flow and are accumulated at the bottom of the ore washing tank in the ore washing process in the prior art, the spiral propelling type multi-section countercurrent ore washing and sorting machine is provided.
