Fig. 2 be dividing element cross section and
The schematic diagram that Fig. 3 has represented to see from the side according to another multistage floatation equipment of the utility model.
The specific embodiment
Multistage floatation equipment according to the utility model relates to the floatation process that infeeds gas (being generally air).This multistage floatation equipment or reactor are vertical cylinder body, and wherein, 2 to 4 adjustings or flotation cells or one of groove are arranged on another.The wall of reactor also constitutes the wall of unit.Be typically for this equipment,, just in all unit, all realized strong mixing through in each unit, adopting a rotor blender.For the sake of simplicity, the flotation cells of in specification, mentioning also can be represented regulon.When with reference to accompanying drawing, only mention two unit in the content after specification, but according to the utility model, this equipment also can comprise more stacked unit.The unit of this equipment foot can be used as and roughly select flotation cells or regulon, and the cleaning flotation cells is used as in the unit of topmost.In some cases, this equipment also can be arranged to work upstream, and wherein, the feed that form foam is supplied to the flotation cells of topmost, and the cleaning flotation takes place in the flotation cells of foot.
Be typically for this equipment, in groove, form powerful vertical circulation flow pattern, and this is to realize through the blender of brute force and vertical baffle plate.Peripheral cone can be used for adjusting the direction of vertical circulation.Substitute and be arranged on the vertical baffle on the reactor wall usually, adopted the vertical plate that more is close to blender, the vertical plate that more is close to blender also can serve as stator simultaneously.
Fig. 1 has shown the vertical reactor 1 that is used for flotation, in this example, is made up of two stacked flotation cells 2 and 3.Previously knownly be, flotation can be carried out in the flotation cell of several successive, but in the present embodiment, flotation cells is one and is arranged on another.The top of upper unit is externally surrounded in foam washing trough 4.Pending slip supplies to the equipment from lower unit through inlet usually, and the foam that forms removes through foam washing trough 4 as overflow from upper unit.The material that does not form foam as yet removes through the outlet 6 in upper unit.Reactor is equipped with hollow shaft 7, and preferably from upper suspension, the rotor blender 8 and 9 of said two units all is connected on this hollow shaft.The required gas of flotation for example air is preferably introduced through hollow shaft or is introduced through other paths that are fit to.Dividing element 10 is arranged between the said unit.This dividing element has slit 11, and via this slit, flotation cells moves to the top flotation cells from the bottom for slip and foam.Dividing element is level substantially, but it also can be inclined upwardly towards hollow shaft in the scope of slit.
As shown in Figure 2, dividing element 10 is not solid plate, but is provided with radial slit 11 therein, and via this radial slit, slip and foam flow to upper unit from lower unit.It is apparent that dividing element also possesses the opening 12 that is used for mixer shafts.As shown in Figure 1, further preferably, in upper unit, above slit, place spoiler 13, to prevent the foam lower unit that flows backwards back.Spoiler is parallel with the slit of dividing element, so they can for example be placed on obliquity.
Floatation equipment is equipped with the stator that surrounds rotor usually, and this stator is made up of vertical plate.According in the equipment of the utility model, be arranged on baffle plate 14 in the reactor at United States Patent (USP) 5,078, the type of describing in 505, wideer than standard baffle plate, leave certain distance from reactor wall.Baffle plate has been replaced stator structure.According to the utility model, baffle plate extends to top edge 16 from the base section 15 of reactor.The radical length of baffle plate (width) is approximately 0.11-0.14 times of reactor diameter, and their outer rim is approximately 0.08-0.1 times of reactor diameter apart from the distance of reactor wall.The number of baffle plate is 6-10, depends on the size of reactor.In addition, the top flotation cells of reactor is equipped with two peripheral cones 17 and 18 at least, and they are arranged between reactor wall and the baffle plate and are positioned at blender 8 and 9 tops.In some cases, in lower unit, need not use peripheral cone.Peripheral cone has in more detail in application WO2010/043763 to be described.The diameter of rotor blender preferably is approximately the 35-45% of reactor diameter, and put in the reactor apart from the bottom or the height of dividing element be the blender diameter 0.7-1 doubly.
When reactor was equipped with the peripheral cone that on the center, rises, pulp flow turned to reposefully, and the mineral grain that is attached in the bubble can not separate from bubble.This material that will form foam very heavy and very difficult be particular importance when rising with air.
Further preferably, in some cases, weaken because upwards flowing of forming of peripheral cone through the guide plate 19 that is connected with each baffle plate.This guide plate preferably is placed in the flotation cells of top at least, and is as shown in Figure 1.Guide plate is connected peripheral cone top, and the 1.5-1.7 that common height apart from dividing element or reactor bottom is the blender diameter doubly.Guide plate is a rectangle, and identical with peripheral cone with the horizontal plane angulation, that is, the angle of 20-40 degree is risen at the center of guide plate orientating reaction device.Guide plate is identical in the length that reactor directly makes progress with baffle plate in the length that reactor directly makes progress, and that width is the pact of baffle plate is half the.Guide plate is connected with baffle plate, therefore with regard to width in bilateral symmetry.
The slip that does not form foam in the flotation cells of bottom can also remove through the outlet 20 that is connected with the bottom flotation cells.Likewise, for example water can 21 be injected into the top flotation cells through entering the mouth.
In all flotation cells, use the rotor blender realized on the blender with under powerful mixing.The mixer instance of this type is as at United States Patent (USP) 4,548,765 with WO2010/043763 in describe.
In some cases, the material that preferably at first will form foam supplies to the top flotation cells, and is as shown in Figure 3.The material that forms foam 22 supplies to the top flotation cells through entering the mouth, and the material that does not form foam in the flotation cells of top is directed to the bottom flotation cells through being positioned over the outside tube connector 23 of reactor.The mud that in the flotation cells of bottom, does not also form foam is through outlet 24 dischargings.
