Abstract
The utility model relates to a pressurizing filtering machine for flotation ore concentrate, which belongs to a solid-liquid separating device and comprises a pressurizing chamber filled with compressed air, etc. An ore slurry tank whose upper part is provided with a filtering main shaft is arranged in the chamber, and a plurality of filtering disk on the main shaft are immersed into ore slurry and rotate in the ore slurry. Under the action of the compressed air, the granules in the ore slurry are adsorbed on the surface of the stainless steel screen of a filtering fan, and filter cakes are formed. The separated water penetrates the inner cavity of the filtering fan and then is discharged through a filtering pipe, a distributing valve and a liquid discharging pipe. The filter cakes are peeled off by an unloading scraper to a scraping plate conveyor and then are conveyed to a discharging device for discharge. The pressure difference of the pressure filtration is 4-5 higher than that of the vacuum filtration, so that the utility model has the advantages of little product moisture, high productive rate, and low energy consumption.

Describe the structure and the embodiment of flotation concentrate pressing filter in detail below in conjunction with accompanying drawing.
Fig. 1 represents the front section view of flotation concentrate pressing filter.
Fig. 2 represents the side sectional view of flotation concentrate pressing filter.
Fig. 3 presentation graphs 1 is along A-A cutaway view.
Fig. 4 presentation graphs 1 is along B-B cutaway view.
As the flotation concentrate pressing filter that Fig. 1, Fig. 2 represent, comprise pressurization storehouse 1, this pressurization storehouse is a cylindrical pressure vessel, under the effect of pressure-regulating device, cause a pressure stable confined space, compressed air enters from air inlet 2, generally make the pressurization storehouse in operating pressure be 0.3 MPa; Pressurization storehouse integral body is horizontal, with 20 supportings of supporting saddle.Set firmly a pulp tank 3 in the pressurization storehouse, pulp-entering pipe 4 communicates (Fig. 2) with the pulp tank bottom, and the forward and backward support of this pulp tank connects firmly mutually with at the bottom of the pressurization storehouse, and the upper end of pulp tank connects firmly the bearing block that filters main shaft 5 in order to install.The filtration main shaft of representing as Fig. 45, it is a hollow tubular axis, and along uniform 20 filtrate pipes 6 of the outer rim of its circumference, these filtrate pipes support by the block set at hollow tubular axis both ends, the corresponding pulp tank upper end that is installed in the filtrate pipe end of distributing valve 9, the inner chamber of distributing valve communicates with discharging tube 10.Equally spacedly on the main shaft be provided with 5 and filter disks 7 filtering, each filters disk and is uniformly distributed along the circumference 20 and filters fan 29; Filter disk and immerse pulp tank, make its liquid level reach the axis that filters disk, promptly immersion depth reaches 50%.As the filter fan 29 that Fig. 4 represents, it is the fan-shaped framework of being made by fiberglass, the outer casing stainless steel silk screen, and its inner chamber communicates with corresponding filtrate pipe 6 on the filtration main shaft; Adjacent filter fan is fixed to be connected with interval stay-bolt 32, pressing plate 31 and guide rail 30 and filters on the main shaft.On the ledge of the pairing pulp tank of each filtration disk a unloader knife 11 is set.Filtration main shaft and filtration disk are dragged by main drive gear, and this mechanism is installed in the top of pulp tank, and it comprises that the main buncher 21 that passes connects master's biography gear-shift mechanism 22, and the final stage gear of this gear-shift mechanism is meshed with the gear wheel 23 that connects firmly filtering on the main shaft.In adjacent two pulp tanks that filter between the disk, an axial flow type stirrer 8 is set, promptly 5 filtration disks are provided with 4 agitators, structure such as Fig. 3 of this agitator represent, it comprises lower end pulp inlet 27, in pulp inlet, settle agitator arm 26, this impeller is connected with stirring main shaft 25, stirs the main shaft upper end and connects stirring buncher 24, and housing top is provided with stirring grout outlet 28.In the pulp tank bottom, and parallel with pulp tank install scratch board conveyor 12, the head of this scratch board conveyor is corresponding with the sealed discharging device 13 that bottom, pressurization storehouse connects.As Fig. 1, sealed discharging device 13 comprises feeding bin 14, and the lower end of feeding bin connects firmly upper sealing ring seat 15, between upper sealing ring seat and the blanking bin 17 discharge sluice valve 16 is set, the lower end of blanking bin connects firmly lower seal ring seat 18, and discharge sluice valve 19 is set down between lower seal ring seat and the discharge gate.
Ore pulp is by pulp-entering pipe 4, enter (Fig. 2) from the bottom of pulp tank 3, the stirring buncher 24 of axial flow type stirrer 8 (Fig. 1, Fig. 3) drives when stirring main shaft 25 and agitator arm 26 rotations, ore pulp sucks in the housing of agitator by pulp inlet 27, stir grout outlet 28 and flow to pulp tank top through stirring to be threaded to vertically, make the ore pulp even particle distribution of pulp tank upper, middle and lower portion thus, eliminated the phenomenon of layered filtration.Compressed air enters in the pressurization storehouse 1 from air inlet 2, makes it cause the confined space of 0.3 MPa.Filtration main shaft 5 passes under gear-shift mechanism 22 and the drive of gear wheel 23 speed changes through main at the main buncher 21 that passes, with 0.38～1.54 rev/min rotating speed filtration disk 7 is rotated, the filter fan 29 that filters disk immerses ore pulp gradually, under the compressed air effect in the pressurization storehouse, solid particle in the ore pulp is adsorbed on the surface of the stainless steel cloth on the filter fan, form filter cake, the gentle inner chamber of stainless steel cloth to the filter fan that then see through of the water that separates excretes through filtrate pipe 6, distributing valve 9 and discharging tube 10; When the filter fan produces mineral syrup liquid, continue under the compressed air effect, the moisture in the filter cake further is depressed into filter fan inner chamber, continues to excrete through filtrate pipe, distributor and discharging tube.Filter cake is dry gradually, it is peeled off to scratch board conveyor 12 through unloader knife 11, be transported to the feeding bin 14 of sealed discharging device 13, open discharge sluice valve 16, filter cake drains into blanking bin 17, closes then and closes the discharge sluice valve, open down discharge sluice valve 19, filter cake excretes, and closes down the discharge sluice valve again, so the upper and lower sealing discharging of alternately realizing.
Advantage of the present utility model: under barotropic state, its filtration pressure difference is than disk vacuum mistake Filter pressure reduction is big 4～5 times, therefore has the advantage that product moisture is low, productive rate is high and energy consumption is low. Through floatation clean coal pressure filtration being tested filter cake moisture 19.2～20.98%, unit are Disposal ability 0.4～0.75 ton/square metre hour, 6.86 kilowatt-hours of electrical energy consumption per tonne of raw coal. Because floatation clean coal moisture reduces, to railway transportation, improve the coke oven thermal efficiency and environmental protection all Significant.
