Description
Technical field
The utility model belongs to mine selecting and purchasing equipment technical field, especially relates to a kind of vortex sieve of ladder screen cloth.
Background technology
Screen cloth face is the vortex sieve in inferior pyramidal net cylinder face is a kind of gravity flow screen; it is the classification for fines; flow through compass screen surface so that ore pulp is for the helical movement; fines is discharged through sieve aperture; coarse grain is discharged through lower pyramid mouth; the shortcoming of this vortex sieve is because screen cloth is arc slope; many in ore pulp can the fine sand grain of open-work slip down along screen surface; manyly the particulate of open-work can to confuse coarse grain and emit through lower pyramid mouth; so waste the treating capacity of ore pulp greatly, this is the difficult problem in vortex sieve operation.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, the vortex sieve of ladder screen cloth easy to use, this device enters in cannelure with ore pulp from feed pipe, ore pulp in cannelure tangentially sprays from feed nozzle, ore pulp moving on the step surface of ladder screen cloth along hand of helix, this device on year-on-year basis slope vortex sieve improve sieve saturating rate be 30%, economize energy is 30% on year-on-year basis.
The purpose of this utility model is realized by following technical proposals:
The vortex sieve of ladder screen cloth of the present utility model, it is characterized in that comprising vortex sieve housing, be cemented in the cannelure of this vortex sieve housing upper periphery, be cemented in the feed pipe on this cannelure two mother rib lateral rotundum, be located at one group of feed nozzle at described vortex sieve housing upper barrel open plate place, be located at the bottom of the tilting feeding tube below described vortex sieve enclosure interior, be arranged on the circular screen I in described vortex sieve housing from top to bottom, the inner ring of circular screen I fixes and the annular ring I equal with the annular diameters of described circular screen I therewith, therewith annular ring I fix and with the circular screen II of described annular ring I equal diameters, the inner ring of circular screen II fixes and the annular ring II equal with the annular diameters of described circular screen II therewith, therewith annular ring II fix and with the circular screen III of described annular ring II equal diameters, the inner ring of circular screen III fixes and the annular ring III equal with the annular diameters of described circular screen III therewith, therewith annular ring III fix and with the circular screen IV of described annular ring III equal diameters, the inner ring of circular screen IV fixes and the solid material efferent duct equal with the annular diameters of described circular screen IV therewith, be connected with the conveying mouth of vortex sieve housing sidepiece at the bottom of described tilting feeding tube.
Described solid material efferent duct is connected with outside through at the bottom of described tilting feeding tube.
Described annular ring I, annular ring II and annular ring III are closed steel ring.
Advantage of the present utility model:
The vortex sieve of ladder screen cloth of the present utility model, this device enters in cannelure with ore pulp from feed pipe, ore pulp in cannelure tangentially sprays from feed nozzle, ore pulp moving on the step surface of ladder screen cloth along hand of helix, proportion due to the ore particulate in ore pulp is greater than the proportion of water, ore particulate rests on the ledge surface of ladder screen cloth, waits for the bump of ore pulp; Under the bump of ore pulp, the particulate being less than sieve aperture is rushed under sieve aperture by ore pulp water, the particulate ore pulp that open-work falls, and the conveying mouth be provided with below shell body at the bottom of tilting feeding tube is discharged; The coarse grain being greater than sieve aperture, by the screen cloth step surface that impacts below, impacts again; Because annular ring I, annular ring II and annular ring III are all closed steel rings, the ore pulp ejected from feed nozzle, along the impact forces of the hand of spiral, is on the surface of every layer of circular screen; Under the ore sand grains dropped on every layer of circular screen surface accept the bump of ore pulp, the sand grains that thoroughly can fall from sieve screen apertures all falls under sieve screen apertures, does not flow in solid material efferent duct by the coarse grain sand grains of sieve aperture and emits; This device on year-on-year basis slope vortex sieve improve sieve saturating rate be 30%, economize energy is 30% on year-on-year basis.
