Filter press for magnesium oxide dechlorination

The invention relates to the technical field of filter presses, in particular to a filter press for magnesium oxide dechlorination, which comprises a filter press body, a guide rail of the filter press body is slidably connected with a plurality of filter plates, each filter plate comprises a first sliding plate and a second sliding plate, and the surfaces of the first sliding plates and the second sliding plates are provided with communicating holes. The communicating hole is communicated with the output end of a pumping device of the filter press body; material storage cavities are formed in the two sides of the first sliding plate, a slurry inlet groove is formed in the surface of the first sliding plate, and the communicating holes communicate with the material storage cavities through the slurry inlet groove; before next filter pressing, polluted filter cloth is conveyed through the winding mechanism, new filter cloth is conveyed to one side of the liquid storage cavity, after the filter cloth is conveye
