摘要（英）：

Provided is a filter-press purifying device for high-concentration iron hydroxide feed liquid in production of ammonium sulfate. The filter-press purifying device comprises a filter press and a diaphragm pump. A compressed air inlet of the diaphragm pump is connected with an air-compressing pipeline, a discharge outlet of the diaphragm pump is connected with a feed inlet of the filter press through a pipeline, a feed end of the filter press is connected with the air-compressing pipeline, a first discharge outlet of the filter press is connected with a second feed inlet of a feed liquid collecting tank and a feed inlet of a feed box, a first feed inlet of the liquid feed collecting tank is connected with a production system, a discharge outlet of the feed liquid collecting tank is connected with a feed inlet of the diaphragm pump, a discharge outlet of the feed box is connected with the production system, a second discharge outlet of the filter press is connected with a feed inlet of a filter cake collecting box, and a discharge outlet of the filter cake collecting box is connected with the feed inlet of the diaphragm pump. The strong filter purifying function of the filter press is utilized sufficiently, so that materials and iron hydroxide byproducts in production of ammonium sulfate can be recycled, while environmental pollution is reduced, and the filter-press purifying device has a high practical value.
