Abstract
The utility model discloses a magnetic separator with self-cleaning accumulated material function, which comprises a plurality of scraping plates, wherein each scraping plate is vertically fixed on the outer wall of the magnetic separator; every scraper blade is all along the axial setting of cylinder, all the scraper blade is followed the outer wall of cylinder is the heliciform setting, and every two adjacent scraper blade corresponds the central angle of cylinder is 25 to 35. At cylinder pivoted in-process, the scraper blade removes to the position that corresponds with the separation tank, the scraper blade can be stored up the mineral particles at the separation tank bottom and promote, mineral particles can produce the motion, and strike under the ore pulp that injects into for the ore deposit passageway, from the gap to the direction motion in tailing groove between two adjacent scraper blades, the piling up of the production of effectual avoidance separation tank, make the smooth and easy flow of the ore pulp in the separation tank, increase area of contact, improve separation efficiency, increase the sorting capacity.
Description
The technical field is as follows:
the utility model relates to a coal washing and selecting equipment field, concretely relates to magnet separator with from long-pending material function of clearance.
Background art:
the magnetic separator is used as important equipment for recycling magnetite powder in the process of heavy-medium coal separation, and the quality of the magnetic separation recycling effect is directly related to the medium consumption level of a coal separation plant. The magnetic separator has the characteristics of high strength magnetism, high medium recovery rate and the like; when the ore pulp separator is used, ore pulp is injected into the ore feeding box 4 and enters the separation tank 6 through the ore feeding channel 5, magnetic substances in the ore pulp are adsorbed to the outer wall of the roller 7 under the action of a magnetic system of the roller 7 and are conveyed into the concentrate tank 8 under the driving of the roller 7, and non-adsorbed ore pulp particles enter the tailing tank 9 along with the ore pulp.
But the magnetic separator is comparatively sensitive to the granularity constitution of granule in the pan feeding, and especially large granule material piles up in separating tank 6 easily, can make the friction that cylinder 7 and accumulational material produced for the area of contact of cylinder 7 and ore pulp diminishes, seriously influences the medium recovery effect and the unit throughput of magnetic separator, and to above-mentioned problem, can only solve through artifical clearance after strict control pan feeding granularity upper limit and the shut down at present.
The utility model has the following contents:
an object of the utility model is to provide an avoid separating the magnetic separator that has from long-pending material function of clearance of long-pending material of groove.
The utility model discloses by following technical scheme implement:
a magnetic separator with a self-cleaning material accumulation function comprises a plurality of scraping plates, wherein each scraping plate is vertically fixed on the outer wall of the magnetic separator;
every scraper blade is all along the axial setting of cylinder, all the scraper blade is followed the outer wall of cylinder is the heliciform setting, and every two adjacent scraper blade corresponds the central angle of cylinder is alpha.
Preferably, the scraper conveyor further comprises a plurality of connecting plates, the connecting plates are arranged tangentially along the outer wall of the roller and fixed on the outer wall of the roller through bolts, and each scraper is correspondingly fixed on one connecting plate.
Preferably, the scraper is made of nonmagnetic stainless steel.
Preferably, said α is 25 ° to 35 °.
The utility model has the advantages that: at cylinder pivoted in-process, the scraper blade removes to the position that corresponds with the separation tank, the scraper blade can be stored up the mineral particles at the separation tank bottom and promote, mineral particles can produce the motion, and strike under the ore pulp that injects into for the ore deposit passageway, from the gap to the direction motion in tailing groove between two adjacent scraper blades, the piling up of the production of effectual avoidance separation tank, make the smooth and easy flow of the ore pulp in the separation tank, increase area of contact, improve separation efficiency, increase the sorting capacity.
Description of the drawings:
FIG. 1 is a schematic diagram of the working state of a magnetic separator in the background art;
FIG. 2 is a schematic structural diagram of the installation of the magnetic separator of the present invention;
FIG. 3 is a distribution diagram of the present invention on a drum;
fig. 4 is a schematic structural diagram of the present invention.
In the figure: scraper blade 1, connecting plate 2, bolt 3, ore feeding case 4, ore feeding passageway 5, separation trough 6, cylinder 7, concentrate groove 8, tailing groove 9.
The specific implementation mode is as follows:
as shown in fig. 2 to 4, a magnetic separator with a self-cleaning material accumulation function comprises a plurality of scrapers 1 and a plurality of connecting plates 2, wherein the connecting plates 2 are arranged tangentially along the outer wall of a roller 7 and fixed on the outer wall of the roller 7 through bolts 3, each scraper 1 is correspondingly fixed on one connecting plate 2, and each scraper 1 is arranged vertically to the corresponding connecting plate 2;
each scraper blade 1 is arranged along the axial direction of the roller 7, all the scraper blades 1 are spirally arranged along the outer wall of the roller 7, and the central angle of the roller 7 corresponding to each two adjacent scraper blades 1 is 25-35 degrees;
in the process of rotation of the roller 7, the scrapers 1 move to the position corresponding to the separation groove 6, the scrapers 1 push the mineral particles accumulated at the bottom of the separation groove 6, the mineral particles move, under the impact of ore pulp injected into the ore feeding channel 5, the mineral particles move from the gap between two adjacent scrapers 1 to the direction of the tailing groove 9, and the mineral adsorbed by the magnetic system of the roller 7 rotates along with the roller 7 until the mineral particles reach the upper part of the concentrate groove 8 and fall into the concentrate groove 8 under the action of gravity;
because the scraper blade 1 is perpendicular to the outer wall of the roller 7, mineral particles can collide with the scraper blade 1 in the rotating process, and when the scraper blade 1 is seriously deformed, the bolt 3 is screwed off, and the corresponding scraper blade 1 is replaced.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
