Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wet screening equipment, in particular to a flushing water device for an anti-blocking screening equipment. Background Technique
[0002] In the production of a concentrator, wet screening equipment is widely used and is often used in combination with grinding equipment. The wet screening equipment has the function of classification, that is, separating the coarse particles and fine particles of the material. The screened product of the screening equipment, namely the fine particle material, enters the next process of the concentrator; the oversize product of the screening equipment, namely the coarse particle material, needs to be returned to the grinding equipment for re-grinding until it is ground fine. Therefore, the fine particle material needs to be discharged in time, otherwise it will affect the overall effect of grinding classification. If the screening effect of the screening equipment is poor, the ground material cannot enter the undersize in time, but returns to the ball mill for re-grinding, which increases the load of the grinding equipment, affects the throughput of the system, and the processing capacity of the concentrator system will also be affected.
[0003] The ore mined in open-pit mines is fed into the screening equipment after being crushed. Since there is silt on the surface of the ore that will agglomerate, the whole agglomerate will directly enter the oversize and return to the grinding. The fine material cannot pass through the screen smoothly due to agglomeration and becomes the undersize product. Therefore, it is necessary to use a flushing water device to wash and disperse the silt impurities on the surface of the material, so that the material is in a loose state, does not agglomerate, and the fine-grained material is more likely to pass through the screen and become the undersize product. The production water of mining enterprises needs to be recycled, resulting in poor quality of production water. The spray holes of conventional flushing water devices are easily blocked by sundries, resulting in uneven flushing water acting on the screen surface. Some materials cannot even contact the flushing water, and the dispersing effect is poor. The screening effect of the screening equipment is not ideal, restricting the production of the concentrator, resulting in the fine-grained material not being able to enter the undersize and returning to the previous operation, affecting the processing capacity of the concentrator.

[0004] The purpose of the utility model is to provide a flushing water device for an anti-blocking screening equipment, which can effectively wash and disperse the materials on the screen, make the materials in a loose state, discharge the fine-grained materials in time, reduce the return amount of the oversize, improve the screening effect of the screening equipment, and enable the concentrator to produce efficiently and smoothly, so as to solve the problems raised in the above background technique.
