Description

TECHNICAL FIELD

[0001] The utility model relates to metallurgical equipment technical field, especially a kind of cleaning device of filter core for anode mud of filter press. BACKGROUND

[0002] Anode mud is insoluble mud-like substance attached to the surface of residual anode or precipitated at the bottom of electrolytic cell in aqueous solution electro-metallurgical process. Generally gray, particle size is about 100-200 mesh, and various components are mostly in the form of metal, sulfide, selenide telluride compound, oxide, elemental sulfur and basic salt. Generally, wet separation or full wet process is used to extract precious metals, rare metals and other valuable metals contained in anode mud to obtain huge economic benefits. Wet separation usually needs multiple filtration, and filter press is generally used to apply certain pressure to anode mud, so that liquid in anode mud is exuded, which is a commonly used solid-liquid separation equipment. For example, the anode mud automatic cleaning system disclosed in Chinese patent document CN201720395134.7 includes a flow guide hopper, a mud discharge pipeline and a filter press arranged at the bottom of the electrolytic cell. The flow guide hopper is connected to the upper surface and the lower surface of the bottom of the electrolytic cell, and the flow guide hopper is in the form of a conical structure with an inclination angle of 38-50 degrees.

The mud discharge port is connected to the mud discharge pipeline, and the mud discharge pipeline transports the anode mud collected by the flow guide hopper to the filter press. After the anode mud is naturally settled, it falls into the bottom of the electrolytic cell and enters the flow guide hopper through the mud discharge port, and finally is transported into the filter press by the mud discharge pipeline. The whole process does not produce floating mud and does not have flow disturbance problem, and realizes timely recovery and treatment of the anode mud without the need to set anode mud settling tank and anode mud intermediate tank.
