Description

Filter device for preparing magnesium sulfate heptahydrate Technical Field The utility model relates to the technical field of preparation of magnesium sulfate heptahydrate, in particular to a filtering device for preparing magnesium sulfate heptahydrate. Background The magnesite flotation tailings can obtain a lot of magnesium carbonate, and magnesium sulfate heptahydrate can be prepared by taking magnesium carbonate as a raw material through the technological processes of dissolution, filtration, evaporation concentration, crystallization and the like. Wherein, the filtration is an important ring, and insoluble impurities such as sediment, ore and the like in the magnesium carbonate solution are removed by filtration. The existing filter device adopts filter cloth to filter, but insoluble impurities can be accumulated on the filter cloth to cause blockage after a period of use, the filter cloth is required to be manually detached for cleaning, and the filter device is troublesome, so that aiming at the current situation, the filter device with the function of self-cleaning the impurities on the filter cloth is urgently required to be developed, and the filter device for preparing magnesium sulfate heptahydrate is more convenient to use, so that the defects in the current practical application are overcome, and the current requirements are met.
