Description
Technical field
The utility model relates to the mine, and a kind of solid-liquid separating equipment in the chemical field is specially a kind of hydraulic classifier.
Background technology
The hydraulic grader is that tiny mineral have the equipment that different sinking speed is carried out classification after utilizing ore grinding in water or in other medium.
In classification process, it mainly is to carry out in ore pulp flow to the flow process of overflow place to the place, ore deposit that ore particle separates, and bigger ore particle sedimentation and tiny ore particle halfway flow to overfall and discharges, and obtains containing the sand return of fine-grained overflow and coarseness simultaneously.
The length of traditional hydraulic grader casing, width, depth dimensions design be key very.Design too narrow material and emit groove easily, do not have the effect of classification too greatly.And downward easily the flowing rapidly of ore pulp when discharge is rough; thereby to open the time stage process destroyed easily when the ore discharge valve; and ascending current is very inhomogeneous in the grading room upper and lower part; because of no ascending water constant-current stabilizer; can not guarantee the flow velocity uniformity of ascending current; cause the wide and thickness confusion of particle size range, have a strong impact on grading effect.
Chinese patent ZL97225727.6 discloses a kind of micron power hydraulic classifier, can realize the multicell classification, but only is applicable to processing 0.005mm～0.1mm particulate mineral aggregate.
The utility model content
Goal of the invention of the present utility model is: the thickness particle easily mixes during at existing hydraulic classifier classification, discharge the defective of rough time stage process destructible, the multicell hydraulic classifier that a kind of classification process is stable, grading effect significantly can be handled the coarse grain mineral aggregate is provided.
The technical scheme that the utility model adopted is: a kind of hydraulic classifier comprises in height being a plurality of grading rooms that ladder is arranged that each grading room is made up of cavity, transmission device and agitating device; Cylindrical section between adjacent two grading room cavitys is interconnected, and each grading room upper end is provided with overflow launder, and the lower end tipping has the ore discharge chamber, is provided with the ore discharge valve between grading room and the ore discharge chamber; Described agitating device comprises the hollow impellers axle, be contained in the worm gear on hollow impellers axle top, be contained in the radial impeller in hollow impellers axle bottom, place in the hollow impellers axle and the top has the lifting arm of lever arm; Be fixed with cam bit on the described worm gear, the lifting arm lower end connects the ore discharge valve, and the lifting arm lever arm is positioned at the worm gear top; Described cavity top is cylindricality, and the bottom is taper, and described impeller is the shape of falling the vertebra and places the cavity bottom.
Ore pulp is fed by the narrow end of grader, and sludge is suspended in the stream of ore deposit and discharges from effluent head, and coarse granule then falls into each grading room cavity bottom respectively according to the sinking speed difference.Transmission device deposits in the teeter chamber to prevent ore in sand form, and prevents contingent vortex phenomenon by the rotation of worm gear drives impeller.Be fixed on cam bit on the worm gear with lifting arm lever arm jack-up, drive lifting arm the ore discharge valve is opened, make sand setting enter the ore discharge chamber and discharge.Because the section of grading room cavity diminishes from top to bottom, so ascending water increases from top to bottom, can form significantly by the granularity layering, and the bottom coarse granule is subjected to the flushing of upwelling, classification once again in infall process.When the ore discharge valve is opened sand grains is discharged at last, the ascending water of each grading room reduces gradually, thereby the sand setting granularity of each chamber also diminishes with regard to corresponding.Thereby guarantee that coarse grained material discharges fast in first Room, short grained material continues to move ahead, and discharges in several grading rooms subsequently, finally reaches the purpose of classification.
The beneficial effects of the utility model: this hydraulic classifier is applicable to that handling granularity is the rough particle of 0.074mm～2mm, and simple in structure, easy to operate, classification process stable, grading effect obviously, also can be realized automatically ore discharge regularly.
Description of drawings
The structural representation of an embodiment of Fig. 1 the utility model.
In the drawings:
The 1-grading room, the 2-transmission device, 3-ore discharge valve,
4-ore discharge chamber, 5-grading room cavity, the 6-overflow launder,
7-hollow impellers axle, the 8-worm gear, the 9-lifting arm,
The 10-impeller, 11-cam bit, 12-lifting arm lever arm.
The specific embodiment
A kind of hydraulic classifier as shown in Figure 1, is included in the layout that laterally is in line, and the upper end flushes on short transverse, and the lower end is four grading rooms 1 that ladder is arranged, and each grading room 1 is made up of cavity 5, transmission device 2, agitating device; Top between adjacent two grading room cavitys 1 is interconnected, and broadens gradually from the first grading room cavity, 5 to the 4th grading room cavitys 5, and each grading room 1 upper end is provided with overflow launder 6, and the lower end tipping has ore discharge chamber 4, is provided with ore discharge valve 3 between grading room 1 and the ore discharge chamber 4; Described agitating device comprises hollow impellers axle 7, be contained in the worm gear 8 on hollow impellers axle top, be contained in hollow impellers axle bottom impeller 10, place in the hollow impellers axle 7 and the top has the lifting arm 9 of lever arm; Be fixed with cam bit 11 on the described worm gear, the lifting arm lower end connects ore discharge valve 3, and lifting arm lever arm 12 is positioned at worm gear 8 tops; Described cavity 5 tops are cylindricality, and the bottom is taper, and described impeller 10 is the shape of falling the vertebra and places cavity 5 bottoms, and are vertically mounted on hollow impellers axle 7 bottoms radially.
Ore pulp is fed by the narrow end of hydraulic classifier, and sludge is suspended in the stream of ore deposit and discharges from overflow launder 6, and coarse granule then falls into each grading room cavity 5 bottom respectively according to the sinking speed difference.Transmission device 2 deposits in grading room 1 to prevent ore in sand form, and prevents contingent vortex phenomenon by 10 rotations of worm gear 8 impeller.Be fixed on cam bit 11 on the worm gear 8 with lifting arm lever arm 12 jack-up, drive lifting arm 9 ore discharge valve 3 is opened, make sand setting enter ore discharge Room 4 and discharge.Because the cross section of grading room cavity 5 diminishes from top to bottom, so ascending water increases from top to bottom, can form significantly by the granularity layering, and the bottom coarse granule is subjected to the flushing of upwelling, classification once again in infall process.When ore discharge valve 3 is opened sand grains is discharged at last, the ascending water of each grading room 1 reduces gradually, thereby the sand setting granularity of each grading room 1 also diminishes with regard to corresponding.Thereby guarantee that coarse grained material discharges fast in first Room, short grained material continues to move ahead, and subsequently second, third, discharge in the 4th grading room, thereby reach the purpose of classification.
Because the effect of cam bit 11, the described hydraulic classifier of present embodiment can realize automatically ore discharge regularly, this just can make it discharge denseer product, and the consumption of having lowered water can prevent the obstruction of grading room cavity 5 simultaneously.In addition, ore particle focuses in the receiver when ore discharge, and this can prevent downward the flowing rapidly of ore pulp when discharge is rough, thereby has avoided opening the ruined possibility of time stage process when ore discharge valve 3.
The ore pulp material size is generally the bulky grain of 0.074mm～2mm in this hydraulic classifier, and maximum is no more than 6mm, and pan feeding concentration is about 20%, overflow granularity is generally 0.10mm～0.25mm, maximum is no more than 6mm, and effluent concentration is about 10%～15%, and sand setting concentration is 50%.
