Description
Technical field
The utility model relates to a kind of Novel pulp settling box, is specially adapted to the precipitation of metal mine high density ore pulp and the concentrating and precipitating bucket of the higher underflow density of acquisition, belongs to solid-liquid separating equipment field.
Background technology
The method of metal current mine high density slurry concentrating precipitation generally adopts multifeed clarifier nature concentrating and precipitating, the deficiency of existence: floor space is large, and efficiency is low; The common raker thickener of employing that the method that metal mine high density slurry concentrating precipitates has, key organism, center agitating device, support, overflow pipe, supporting leg and drainage conduit form, the main deficiency existed: energy consumption is large, and maintenance cost is high.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide the Novel pulp settling box that a kind of floor space is little, Non-energy-consumption, thickening efficiency are high.
In order to achieve the above object, the technical scheme that the utility model is taked is: include as the body of shell, the support being arranged on body upper, the drainage conduit that is arranged on overflow pipe outside body upper, is arranged on supporting leg outside underpart, is arranged on underpart; It is characterized in that: also comprise the froth breaking mineralizer in the middle part of rack-mount end, be arranged on the feeding device on froth breaking mineralizer top, be arranged in the middle part of body and swash plate that the mixing device of support bottom, radial skew inside body and outside mixing device are installed, be arranged on disperser that in the middle part of mixing device and upper end is connected with the discharge nozzle of froth breaking mineralizer, the overflow pipe of feeding device is connected with the feeding pipe of mixing device.
The utility model is owing to devising for the feeding device of classification process, for the structure such as flocculant and ore pulp well-mixed froth breaking mineralizer, the mixing device for the rapid free settling of the floc sedimentation in ore pulp, the swash plate for increasing settling area, the disperser that disperses for ore pulp, improve the mixed effect of ore pulp and flocculant, improve the sinking speed of floc sedimentation in ore pulp, slurry concentrating efficiency is high; The height of this technical scheme body compared with common rake concentrator is more than the twice of body internal diameter, highly higher, the time of staying of ore pulp in body is longer, and the pressure that floc sedimentation is subject to is larger, pulp density after compression is also higher, and the concentration and settlement effect of ore pulp is better; This settling box Non-energy-consumption in addition, for user saves electric energy and maintenance cost.
Theory practice proves: when being added by flocculant in conventional mine tailing ore pulp, although ore pulp defines floc sedimentation state, mutually interfere between floc sedimentation, and sinking speed raising is also not obvious; If joined by flocculant in thin ore pulp, ore pulp can form large floc sedimentation rapidly, and occur clear water between floc sedimentation, floc sedimentation becomes free settling from hindered settling, and sinking speed may improve decades of times even hundreds of times; This technical scheme utilizes flocculant can form large floc sedimentation in thin ore pulp, realizes the principle of free settling and design.
The important difference of this technical scheme and common rake concentrator, the filter course of tens centimetres high is upwards had exactly from the upper surface of mixing device, also can be called and filter subsiding belt, this filter course is by little floc sedimentation, granule at large, flocculant remaining in water and a large amount of water composition, in this filter course, along with the rising of current, little floc sedimentation, granule continues to be flocculated agent and catches the large floc sedimentation of formation and drop to Compression Settlement band, the quality of water becomes totally transparent, finally rise to clear water layer, there are again many little floc sedimentations newly simultaneously, granule and remaining flocculant are from the top of mixing device out, constantly add to filter course, form a balance dynamically.
The utility model devises, and feeding device is provided with feeding pipe, control valve K, cyclone classification body, mine tailing discharge nozzle, overflow pipe; In the middle part of the overflow cylinder that mine tailing discharge nozzle is arranged on froth breaking mineralizer and the top of taper dispersion plate; Overflow pipe one end is connected with cyclone classification body overfall, and the other end is connected with the feeding pipe of mixing device.The Main Function of described feeding device: the mixed ore pulp of ore pulp and flocculant is delivered to feeding device by Pulp pump, regulates the pressure of mixed ore pulp by control valve K, improve treatment effect, be applicable to the mixed ore pulp of variable concentrations different pressures; Make mixed ore pulp by quality grading by cyclone classification body, heavier high-concentration ore slurry is ejected into the top of taper dispersion plate by mine tailing discharge nozzle, and lighter low concentration ore pulp enters the inside of mixing device by overflow pipe; Because flocculant is relatively light, the inside of mixing device to be entered by overflow pipe along with lighter low concentration ore pulp, form large floc sedimentation and realize free settling.
The static settling test in laboratory carries out with 1000ml standard graduated cylinder, settling test result shows, adopt identical flocculant usage, feed ore concentration be 8% than feed ore concentration be 20% sinking speed faster, underflow density is more or less the same, and feed ore concentration is when being 26%, the effect adding flocculant is not fairly obvious; This technical scheme relies on this principle exactly, by cyclone classification body, is added to by flocculant in the ore pulp of low concentration, forms large floc sedimentation and realize free settling.
The utility model devises, and froth breaking mineralizer is provided with blast pipe, staving, upper spoiler, lower spoiler, overflow cylinder, taper dispersion plate, uniform distribution plate, discharge nozzle; Blast pipe is arranged on the top edge of staving; Upper spoiler, lower spoiler, taper dispersion plate are arranged on the inner side of staving from top to bottom successively; Overflow cylinder is arranged on the upper center of taper dispersion plate.
Described overflow cylinder is rolled by wear-resisting steel plate and forms, and the upper limb of overflow cylinder and lower edge have several " rectangle " to slot respectively.Its Main Function: be ejected into the heavier high-concentration ore slurry in the top of taper dispersion plate through overflow cylinder side wall collision rift, part ore pulp overflows on inferior pyramidal dispersion plate through " rectangle " fluting of cylinder upper limb, another part ore pulp is slotted by " rectangle " of cylinder lower edge and is flowed automatically on inferior pyramidal dispersion plate and collide with overflow pulp, ore pulp is through the process such as " shunting ", " falling ", " collision ", " mixing ", flocculant mixes with ore pulp, and remineralization efficacy is good; Consumed the kinetic energy of ore pulp by taper dispersion plate and overflow cylinder, consumed the kinetic energy of ore pulp by lower spoiler, upper spoiler further, the bubble simultaneously in ore pulp is discharged by blast pipe, avoids bubble and enters settling box, improve flocculation sediment effect.
The utility model devises, and disperser is provided with feeding pipe, cone cylinder dispersion plate, cone, bottom part fall apart; The lower end of feeding pipe is connected with the upper end of cone cylinder dispersion plate, and bottom part falls apart to be arranged on and bores cylinder dispersion plate lower end inside, and cone is arranged on bottom part and falls apart upper center.
