Embodiment 1

[0033] as attached figure 1 , a filter press system in the production process of manganese sulfate, the filter press system includes a pressure tank 101, a pressurization device, a moisture measurement module and a control system; the pressure tank forms a sealed working space and is formed by an air compressor High-pressure space; the pressurization device includes a screw compression rod 102, a plurality of filter press plates 104 and a driving device 103; the screw compression rod 102 rotates under the power of the driving device 103, thereby opening the compression stroke and compressing A plurality of filter press plates 104; the filter press plates 104 are used to filter the moisture in the pulp and guide the moisture to the collection container; the moisture measurement module enters the filter press chamber 108 with the pressure increase in the latter part of the filter press , and measure the water content in the filter residue; the control system is connected to the ...

Embodiment 2

[0048] This embodiment should be understood as at least including all the features of any one of the foregoing embodiments, and further improvements on the basis thereof;

[0049] In the compression stroke of the filter press system, due to the need to compress the plate shoulder 204 with a strong pressure, the pressure reaches 4 to 5Mpa and maintains it for a period of time, which will easily cause excessive loss of the plate shoulder 204; The pressing time directly affects the total duration of the pressing process, so the moisture measurement module is used to measure the water content of the filter residue to further optimize the overall pressing process;

[0050] The moisture measurement module can measure the water content in the filter residue without contact by using the principle of high-frequency microwave; microwave is a kind of high-frequency electromagnetic wave, and the attenuation and phase change generated when microwave penetrates the medium are mainly determin...

Abstract

The invention provides a filter pressing system in a manganese sulfate production process. The filter pressing system comprises a pressure tank, a pressurizing device, a moisture measuring module and a control system; the pressure tank forms a sealed working space, and an air compressor is adopted to form a high-pressure space; the pressurizing device comprises a spiral compression rod, a plurality of filter pressing plates and a driving device; the spiral compression rod is driven by power of the driving device to rotate, so that a compression stroke is started, and the filter pressing plates are compressed; the filter pressing plate is used for filtering filtrate in ore pulp and enabling the filtrate to enter a collecting container through a plurality of drainage holes in the spiral compression rod; and the moisture measuring module is used for measuring the moisture content in filter residues in the filter pressing process and adjusting the pressure and the pressure maintaining time of the filter pressing system according to the moisture content, so that the working efficiency of the filter pressing process is optimized.

Description

technical field [0001] The invention relates to the field of pulp processing machinery. Specifically, it relates to a filter press system in the production process of manganese sulfate. Background technique [0002] In the production process of high-purity manganese sulfate, it is first necessary to reduce the manganese dioxide ore to obtain the semi-finished powder of manganese oxide, and then continue to remove iron and vulcanization after pulping the semi-finished powder of manganese oxide. Miscellaneous process to obtain the secondary filter slurry; finally through the filter press equipment, filter the high cobalt slag (Co, Ni, Zn, Cu, etc.) impurities in it, so as to finally obtain a high-concentration manganese sulfate solution. [0003] In the traditional filter press process and equipment, plate and frame filter press or box filter press is generally used. After the liquid in the pulp is poured into the filter press plate by high-pressure equipment, the filter memb...
