Abstract

The invention relates to a filter press device, in particular to a filter press device for producing nanometer calcium carbonate. The invention provides a filter press device for nano calcium carbonate production which can automatically pull plates and conveniently remove residual solids. A filter press device for producing nano-calcium carbonate, comprising: a bottom plate, a first support frame is arranged on one side of the bottom plate; a support plate, two support plates are arranged at intervals in the middle of the bottom plate; a feeding mechanism, the bottom plate is far away from the first support frame A feeding mechanism is arranged on one side; a filtering mechanism is arranged between the two supporting plates; a discharging mechanism is arranged at the bottom of the two supporting plates. Through the intermittent movement of the discharge mechanism and the first cable intermittently pulling the plates and frames apart, the structure is simple and the efficiency is stable.

Description

technical field [0001] The invention relates to a filter press device, in particular to a filter press device for the production of nanometer calcium carbonate. Background technique [0002] The production process of nano-calcium carbonate generally uses limestone as raw material, and is prepared through calcination, digestion, carbonization, separation, drying, etc. The liquid-solid separation stage of nano-calcium carbonate suspension usually uses a plate and frame filter press to obtain nano-carbonic acid. For calcium solids, in a complete filter press process, it is necessary to manually remove the evenly arranged adjacent plates and frames one by one, so that the filter cake falls off by itself, which is not convenient for the factory environment of mass production. There will be residual solids on the plate frame and filter cloth and should not be removed, which will affect the next filtration effect. [0003] Therefore, there is an urgent need to develop a filter pre...
