The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of liquid-solid piece-rate system of suspension as shown in Figure 1, be made of following structure: suspension liquid bath 1 is delivered to filter 3 with the slurries after the desiliconization by inlet valve 7, and the turbid solution after filter 3 will filter is sent suspension liquid bath 1 back to by circulating valve 9; Clear solution after filter 3 will filter is delivered to clear liquid groove 5 by bleeder valve 8; Solid filter residue and attached liquid thereof after filter 3 filters entered filter residue storage tank 6 from the filter bottom by residual cake valve 10; Suspension liquid bath 1, clear liquid groove 5 and mistake filter residue storage tank 6 are located at the below of filter 3; The outlet of suspension liquid bath 1 is provided with filter feed pump 2; Inlet valve 7, circulating valve 9 and bleeder valve 8 are located on the pipeline that links to each other with filter 3, inlet valve 7, circulating valve 9, bleeder valve 8 and filter feed pump 2 are electrically connected with PLC control panel on the filter 3, and the PLC control panel is regulated start-stop, the revolution of filter feed pump 2 and carried out control automatically; The bottom of filter 3 is provided with and is used for and will filters the solid filter residue of gained and the deslagging spiral reamer 4 that attached liquid rubbed and sent into the filter residue storage tank thereof; Residual cake valve is electrically connected with torque sensor on the filter.
The utility model operation principle is as follows: an one work period comprises the steps: circulation step, suspension enters the suspension liquid bath, slurries in the suspension liquid bath are sent into filter through the filter feed pump that is located at the outlet of suspension liquid bath, the turbid solution that filters gained returns the suspension liquid bath, suspension is meant and once pressurizes alumina producing to contain admittedly after the desiliconization be the slurries of 40～70g/L, or to contain admittedly behind the alumina producing secondary atmospheric silicon removing be the slurries of 15～25g/L; Filter the deslagging step, the clear solution that filters gained enters the clear liquid groove, filters the solid filter residue of gained and attached liquid thereof and discharges from filter and fell into the filter residue storage tank, and the spiral reamer of filter bottom will filter the solid filter residue of gained and attached liquid thereof and send and be the filter residue storage tank; The accumulation of energy step only is transported to filter with the liquid in the suspension liquid bath, the filter internal pressure is raise put aside energy; Exfoliation step, the pressure in the filter discharges, and makes the energy recoil of savings in the filter hang over filter residue on the filter cloth, and filter residue falls to filter cone bottom.
Opening or closing of described inlet valve, bleeder valve and circulating valve, the filter feed pump open or stop, revolution regulates and all to be controlled automatically by the PLC on the filter; Torque sensor on residual cake valve and the filter is chain, controls opening or closing of residual cake valve automatically by PLC.
