The invention relates to a structure of a concentration pool underflow pump inlet filtering device. The structure comprises an ore pulp inlet pipe (1), a filtering device (2), an outlet pipe (3) and an underflow pump (4), the filtering device (2) is an upright thick wall steel tube, grilles (21) are installed in the thick wall steel tube and used for filtering impurities in the ore pulp, the grilles (21) are axially or radially distributed in the thick wall steel tube, a bottom plate (23) is welded at the bottom end of the thick wall steel tube, a top cover (22) is disposed at the top end of the thick wall steel tube, and the top cover (22) is connected with the thick wall steel tube through a set screw (5). The ore pulp inlet pipe (1) is mounted on the upper portion of the thick wall steel tube, the outlet pipe (3) is disposed on the lower portion of the thick wall steel tube, during working, the ore pulp enters into the filtering device (2) through the ore pulp inlet pipe (1) to be filtered, and then the filtered ore pulp enters into the underflow pump (4) through the outlet pipe (3). The concentration pool underflow pump inlet filtering device has the advantages that the manufacturing and installing are simple, the underflow pump device with a high value can be effectively protected, and unnecessary economic losses are reduced.
Description
technical field [0001] The invention belongs to the technical field of iron ore concentrate long-distance transport pipelines, and in particular relates to an inlet filter device for a concentration pool bottom flow pump. Background technique [0002] Iron concentrate concentration pools are generally open pools. During the production process, it is easy for foreign matter to fall into the pool. Once the object falls into the pool, it will flow into the underflow pump along with the iron concentrate into the delivery pipeline, which not only causes foreign matter to The damage of the pump body, and the shutdown of production will affect the production efficiency, and eventually cause unnecessary economic losses. Contents of the invention [0003] The invention designs a filter device for the bottom flow pump inlet of the concentration pool, which solves the problem of unnecessary economic loss caused by damage to the body of the bottom flow pump caused by foreign matters i...
