Description

Sedimentation and rotay-flow sizing machine

The utility model relates to a kind of classifying equipoment, particularly a kind of sedimentation, cyclosizer.

" classification " is meant solid material difference according to particle sinking speed in fluid (water or air), and press the granule size separating process, the sinking speed of particle is not only relevant with granular size, but also it is relevant with factors such as the density of solid material, shapes, classification also will be subjected to the influence of pulp density and viscosity in water, therefore classification is not strict is undertaken by the grain graininess difference, it is very inaccurate that this just makes partition size separate, the coarse granule material enters the classification overflow, the fine particle grain enters sand setting, and causes classification low.Existing classifying equipoment resembles spiral classifier, and its floor space is big, the device structure complexity, and classification efficiency is low, generally at 20%-30%; The classification efficiency of hydrocyclone is only at 20%-30%, and cause can't operate as normal owing to sand setting stops up, the classifying equipoment of other type, and as hydraulic classifier, classification efficiency is lower, between 10%-30%.

The sedimentation, the cyclosizer that provide a kind of classification efficiency high is provided the purpose of this utility model.

The purpose of this utility model realizes in the following manner: into slurry central cylinder is housed in the grader cylindrical shell, grader cylindrical shell bottom is provided with sand setting orifice plate and the outlet of coarse granule sand setting, grader cylindrical shell periphery wall is provided with stock inlet and fine grained row overflow lip, stock inlet advances to starch the central cylinder lower cone through channel connection, the transmission vertical shaft runs through into slurry central cylinder, eddy flow fixed guide comb drum and eddy flow rotation dispersion impeller are positioned at into, and slurry central cylinder lower cone bottom is loaded on the transmission vertical shaft, advance to starch the central cylinder periphery wall and be provided with fine grained classification mouth just, the transmission vertical shaft is driven through transmission mechanism by motor, is supported on the support platform at grader cylindrical shell top; For preventing that into the vibration of slurry central cylinder is excessive, bottom control centre cylindrical shell pull bar is housed on the grader cylinder inboard wall.

The utility model can realize in the flyash wet classification that thickness is separated efficiently, improve the fineness of flyash, guarantee that flyash meets the fineness of the appropriate level of respective country standard code, use the steady quality of ash in order to building material industry, national important Architectural Equipment construction, make concrete admixture, reduce cement consumption, improve late strength of concrete, improve workability, reduce the heat of hydration, to realize turning waste into wealth protection environment, and the life-span of storage ash field, corresponding prolongation thermal power plant; Can realize the wet separation of metal and non-metal solid in mine ore dressing, fine grained separates with coarse grained, reduces fine grinding abrasion power, improve the breeze grade, stable equipment operation can adapt to the variation of different pulp densities, and operation control is simple, classification efficiency can reach 80%-85%, floor space is little, and cost is low, and is easy to maintenance, life-span is long, is a kind of desirable update grader.

Accompanying drawing has provided an embodiment of the present utility model.

With reference to the accompanying drawings the utility model is described in further detail.

With reference to Fig. 1, into slurry central cylinder 9 is housed in grader cylindrical shell 2, the bottom is provided with sand setting orifice plate 16 and coarse granule sand setting outlet 17, periphery wall is provided with stock inlet 1 and fine grained row overflow lip 11, and fine grained row overflow lip 11 is higher than stock inlet 1, support platform 10 is loaded on grader cylindrical shell 2 tops, and transmission vertical shaft 18 runs through into that slurry central cylinder 9 is loaded on the support platform 10; Advance to starch central cylinder 9 periphery walls and be provided with fine grained classification mouth 12 just, its lower end is coniform, stock inlet 1 through passage with enter to starch central cylinder 9 lower ends and be communicated with, eddy flow fixed guide comb drum 14 and eddy flow rotation dispersion impeller 15 are positioned at into, and slurry central cylinder 9 lower cones bottom is loaded on the transmission vertical shaft 18, with reference to Fig. 3, Fig. 4, Fig. 5, Fig. 6, eddy flow fixed guide comb drum 14 and eddy flow rotate dispersion impeller 15 and are the disk of offering some waist shape grooves along the disk tangential direction, and both rotation directions are opposite; Dragging motor 6 is loaded on the bearing support 3, and driving transmission vertical shaft 18,8 through small belt pulley 5, big belt pulley 7 is the cardan-shaft suspension seat; With reference to Fig. 2, sand setting orifice plate 16 is a circular slab, and radially circumference has some circular holes.Bottom control centre cylindrical shell pull bar 13 is housed on grader cylindrical shell 2 inwalls prevents that into 9 vibrations of slurry central cylinder are excessive, 4 is the AC frequency conversion controller of dragging motor 6.

The utility model course of work is as follows: ore pulp enters central cylinder lower cone turbulization from stock inlet 1, part proportion is little, the solid that particle is thin upwards floats after fine grained classification mouth 12 overflows just again through 11 outflows of fine grained row overflow lip, reach classification just, another part enters eddy flow fixed guide comb drum 14 macropores and enters eddy flow rotation dispersion impeller 15 again, eddy flow rotates dispersion impeller 15 and drives rotation by transmission vertical shaft 18, its rotating speed is adjusted motor speed by AC frequency conversion controller 4 makes eddy flow rotation dispersion impeller 15 reach the rate maximum, whole ore pulp produces rotational field in central cylinder 9, the rotational field central speed is zero, heavy coarse granule free settling, part proportion is little, the solid impact sand setting orifice plate 16 that particle is little upwards floats, up to overflow size separation, another part is thick, heavy particle moves to spigot 17 directions with helical trajectory under the effect of rotational field, reach the classification purpose, realize pressing proportion simultaneously and separate.
