Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
See accompanying drawing 1-4, this three products heavy medium cyclone disclosed in this invention, comprises heavy-media suspension entrance 1, one section of truncated cone-shaped cyclone 2, raw ore feeding mouth 3, two sections of cone cyclones 4, concentrate outlet 5, chats outlet 6, mine tailing outlet 7, connecting pipe 8.
One section of truncated cone-shaped cyclone and two sections of conical cyclones are connected in series, and wherein one section of truncated cone-shaped cyclone one end is provided with heavy-media suspension entrance and mine tailing outlet, and the other end is provided with raw ore feeding mouth; One end of two sections of conical cyclones is provided with concentrate outlet, and the other end is provided with chats outlet.Installation form between one section of truncated cone-shaped cyclone and heavy-media suspension entrance is involute mode, as shown in Figure 2, heavy-media suspension entrance is arranged on the side of one section of truncated cone-shaped cyclone, its suspension pan feeding pipeline is arc shape pipeline, adopt involute mode to install setting between itself and one section of truncated cone-shaped cyclone, the cone angle of one section of truncated cone-shaped cyclone is defined between 0-20 degree.Tangent line pan feeding is had to change involute pan feeding into the enter material way of one section of feed cylindrical cyclone, rounder and more smooth relative to tangent line pan feeding, decrease turbulent phenomenon, thus the impact wear reduced medium inlet, also in a disguised form increase the volume of one section of circular platform type cyclone, angle of taper becomes 0 ° ~ 20 ° truncated cone-shaped cyclones, like this can when ensureing to enter two sections of cyclone overbottom pressure, improve the concentrated effect of cyclone one section, the density of suspending liquid entering two sections of cyclones is improved relatively.
Two sections of conical cyclones are bicone cyclone, and it comprises the slender cone section of leading portion and the big-taper-angle taper body section of back segment, and it is into a single integrated structure that slender cone section and big-taper-angle taper body section pass through Flange joint; The tapering of its slender cone section is between 0-20 degree, and the tapering of its big-taper-angle taper body section is between 20-180.Conical for two cylindrical sections cyclone is become two sections of bicone structures, and upper end conical section cone angle is 0 ° ~ 20 °, and lower end conical section is the large cone angle of 20 ° ~ 180 °.Due to adopt double tapered angle, be enter two sections suspension inspissation strengthen, substantially increase the separating density of two sections of cyclones, thus realize effective sorting of high density mineral.Also change involute by one section into the connected mode of two sections to be connected simultaneously, can be that the mixture of a section of remaining suspension, chats and concentrate enters two sections with rounder and more smooth form like this, realize two sections of sortings in advance, reduce the wearing and tearing to tube connector.
As shown in Figure 1: density is that in 1.8 ㎏/L ~ 2.4 ㎏/L heavy-media suspensions, low-density suspension is fed with involute in form with the edge of certain speed by truncated cone-shaped cyclone by heavy-media suspension entrance, and the non magnetic ore of high density is directly fed by gravity by raw ore feeding mouth.Ore, after one section of truncated cone-shaped cyclone and the sorting of two sections of cone cyclones, can realize the high density sorting of 2.4 ㎏/L ~ 3.2 ㎏/L, and the high density chats product obtained is exported by chats and discharges, and concentrate product is exported by concentrate and discharges.The concentrate of discharging, chats and mine tailing carry out the dehydration of product and the recycling of dense media by the method for dehydration and dielectric film filter.Each angle in the present invention includes two endpoint value.
As shown in Figure 2: the entrance of one section of circular platform type cyclone heavy-media suspension adopts the entry mode of involute, rounder and more smooth relative to tangent line pan feeding, decrease turbulent phenomenon, thus the impact wear reduced medium inlet, also in a disguised form increase the volume of one section of circular platform type cyclone, improve the disposal ability of equipment.
The big-taper-angle taper body section of one section of truncated cone-shaped cyclone and two sections of conical cyclones, all adopts involute mode to be connected between they with connecting pipe.Connecting pipe is integral by Flange joint by multistage arc pipe.
As shown in Figures 3 and 4: the connecting pipe of a section and two sections, adopting the pipeline of involute mode to connect, can be that material enters Pre-sorting before two sections of prerequisites, keep laminar stable, reduce the wearing and tearing to tube connector, increase the volume of two sections of bicone cyclones, improve the disposal ability of equipment.
