Flow up feeding mouth, upper up-flow feeding mouth is located at the bottom of shallow-tank separator ontology 1, suspension upper up-flow pipe arrangement direction with it is shallow
The bottom of slot sorting machine ontology 1 is parallel, and the size of the pars infundibularis big opening end of upper up-flow device 3 measures ability by shallow slot and medium follows
Circular rector determines, generally occupies the 15%-30% of global cycle amount, and realization reduces cost, reduces maintenance, easy to adjust, reduces work
It measures, reduce operation difficulty, enhance stability of suspension and separating effect in shallow slot, while by level stream feeding mouth and upper
Up-flow feeding mouth is both provided with cloth flowing plate, and cloth flowing plate is equipped with several cloth discharge orifices, and the aperture of cloth discharge orifice is less than sorting particle lower limit
50%, can effectively prevent after shutting down during medium back flow, remaining coarse granule is sunk in the channel of upper up-flow in shallow slot,
Upper up-flow pipeline is blocked, coarse granule, which enters conjunction medium bucket, also to be influenced to close the monitoring of matter bucket density, and one side suspension can pass through
Cloth discharge orifice, another aspect cloth discharge orifice can prevent coarse granule from passing through, and reduce and close pollution of the matter bucket from sorting material residue, improve
The accuracy of separating density.
