Cambered surface sprawls the mine-feeding equipment of film concentration machine
Technical field
The utility model belongs to gravity separation technology and equipment field, be related to one kind be exclusively used in fine-particle minerals sorting set
It is standby --- cambered surface sprawls the novel ore feeding device of film concentration machine.
Background technology
The current increasingly poor thin hydridization of mineral resources, thus it is low to head grade, disseminated grain size is thin, complicated components difficult ore dressings
Stone sorts and fine-particle minerals sorting technology becomes the focus that Mineral Processing Industry is attracted attention.The fine fraction in tailing is recycled in gravity treatment
Valuable mineral, beneficiation cost is low, technological process is simple, production management is convenient, pollution-free, efficient gravitational separation equipment is useful to realizing
The recycling of mineral is most important.
It is peculiar shape of the ore pulp by equipment to sprawl stream film gravitational separation equipment, forms millimetre-sized stream film, cambered surface sprawls stream
Flow of slurry is gradually sprawled thinning from top to bottom in circular conical surface when film sorting machine sorts, and the stream film flow velocity of formation gradually slows down, ore pulp
Film concentration machine surface is sprawled in cambered surface and rapidly and evenly sprawls into thin stream film, and ore pulp is in very thin fluid media (medium) in thin stream film
The effect of the shearing dispersion pressure of dispersion pressure and equipment rotary motion is sheared in layer by itself fluid and enhances fine mineral particle
Suspension, loose, layering and enrichment process.Effectively realize effective sorting of wide grade fine grained valuable mineral and gangue.
In thin film concentration, the shearing of ore pulp itself internal fluid sprawls film concentration machine items mineral processing index to cambered surface
Raising has facilitation.But industrially lack efficient, the economic and practical ore feeder for sprawling film concentration machine, Mou Xieliu at present
What film preparation equipment used is all fixed, such as cannot uniformly generate efficient wave to the flat of ore used in suspended vibrating concentrating machine with conical surface
Dynamic stream film layer, it is limited to mining area domain, it is difficult to which that multi-direction generation largely sprawls stream film layer on sorting bed surface.Therefore, stream film is sprawled
Reselection technique theory and practice it is further research and it is perfect, have to the promotion of microfine sludge mineral technologies very important existing
Sincere justice.
Utility model content
The utility model provides one kind and being exclusively used in fine-particle minerals screening installation --- and cambered surface sprawls the new of film concentration machine
Type mine-feeding equipment.
Cambered surface described in the utility model sprawls the mine-feeding equipment of film concentration machine by being formed to mine cone disk and mine-separating box body, gives
Mine cone disk is located in mine-separating box body;Directly connected with concentric shafts to mine cone disk by concentric axis connection with mine-separating box body to mine cone disk
It connects and dynamic with shaft rotation, bores disk for controllable rotating speed, mine-separating box body is connected and fixed to support arm with concentric shafts by bearing or sets
Standby upper not dynamic with shaft rotation, concentric shafts are driven by shaft coupling and frequency modulation motor connecting shaft;
It is with horizontal plane into the conical surface at 25 ° ~ 35 ° angles to mine cone disk, is 8 or more sharp miniatures to mine by barrier partitions
Area, each point miniature are provided with gape to mining area end;
Mine-separating box body is cylinder;Paraxial hold in top of the box is equipped at one third into mine hole;Box baseplate outer three is divided
A part be equipped with reverse flow baffle, rest part hollow out;Reverse flow baffle and sharp miniature are opposite to the gape of mining area end, and with
Horizontal plane is at 5 ° -10 ° of angle;Height-adjustable bolt is equipped with outside mine-separating box body for being fixed on support arm or installation
On device housings.
The course of work of the utility model:Mine-separating box body is fixed on support arm with four height-adjustable bolts or sets
Standby upper, when work, frequency modulation motor drives concentric shafts to drive and bores disk to mine and rotate by shaft coupling, by the ore pulp of appropriate concentration from into
Mine hole is fed bores panel surface to mine, and ore pulp is evenly distributed to each sharp miniature to mining area, with the fortune for boring disk to mine by baffle
Turn, ore pulp be discharged from sharp miniature to mining area end mineral ejection hole largely by the vacancy section of mine-separating box body bottom rapidly and evenly
It spreads into cambered surface and sprawls the surface of film concentration machine, while generating the wavy cambered surface of interval pulsating fish scale and sprawling stream film, few portion
It gives on the reverse flow baffle of box baseplate, reverse flow baffle makes ore pulp flow back into the vacancy section of mine-separating box body bottom, then feeds
The surface of sorting machine.
The beneficial effects of the utility model:1, sharp miniature can effectively facilitate ore pulp to the mineral ejection hole in mining area and sprawl stream in cambered surface
Film sorting machine surface is rapidly and evenly sprawled, and is generated the wavy cambered surface of interval pulsating fish scale and sprawled stream film, ore pulp itself stream
Internal portion shear action increases substantially every mineral processing index of sorting machine, creates conditions for effective sorting of subsequent mineral;2、
The ore pulp of reverse flow baffle being provided with conducive to this region is flowed to flows back into vacancy section;3, mine-separating box body uses height-adjustable spiral shell
Bolt is fixed on support arm or on device housings, is convenient for the flexible modulation of device height;4, device overall structure is simple,
Operation noise is small, and low energy consumption, is easily installed, Operation and maintenance.
