Description
Technical field
The utility model belongs to the technical field of other metallic ore dry method degree of depth sheddings such as raw coal and iron, phosphate, lead, zinc, classifying equipoment, specifically a kind of spiral ore deep-graded sieve.
Background technology
Present domestic Coal Preparation Plant is subjected to the restriction of the effectiveness of classification of existing vibrosieve equipment, and the raw coal separation granularity is now 13mm or 25mm.Along with the raising of coal winning technology mechanization degree, in raw coal, fine coal content increases the also raising thereupon of ash content, sulphur content greatly.The many high-sulfur smalls of China are used as power and must carry out washing with coal over environmental requirement.Although this partition size obtains economic benefit preferably to washing thermal coal, has also seriously affected the cleaning percent of raw coal and the clean utilization of coal.
The fluid bed Gas-making Furnace of coal gasification industry has strict requirement to the pulverized coal particle of pan feeding, and being necessary for granularity is the following pulverized coal particle of 6mm, can make like this pulverized coal friring abundant, and furnace temperature is stable, fully contacts with gasifying agent, obtains better gasification result.The restriction of vibrated screening plant effectiveness of classification, obtaining granularity is comparatively difficulty of the following pulverized coal particle of 6mm.For this reason, the classifying equipoment of the following granularity of research and development 6mm is very necessary.
Summary of the invention
The utility model is in order to solve in existing coal classification process, vibrosieve sizing of equipment precision is not enough, sieve aperture holds susceptible to plugging problem, a kind of compass screen surface self-cleaning function that possesses is provided, need not the high pressure water washing compass screen surface, energy-conserving and environment-protective can realize that the spiral ore deep-graded of dry method deep-graded sieves.
In order to address the above problem, the utility model is taked following technical scheme: a kind of spiral ore deep-graded sieve comprises drive motors, decelerator, feed chute, propellers, screen drum, discharge gate, material collecting tank and base; Below, screen drum bottom is provided with material collecting tank, and screen drum and material collecting tank are arranged on base, and screen drum one end connects discharge gate, and the other end connects into hopper, is equipped with propellers in screen drum, and propellers one end is connected with decelerator, and decelerator is connected with drive motors.
Described screen drum comprises gripper shoe I, gripper shoe III, screw rod, fixed ring sheet and rotating ring sheet, the screen drum two ends are respectively equipped with gripper shoe I and gripper shoe III, be equipped with screw rod between gripper shoe I and gripper shoe III, the screw rod two ends are screwed with nut, screw rod is provided with some fixed ring sheets, is provided with the rotating ring sheet between adjacent fixed ring sheet; Described fixed ring sheet and rotating ring sheet center have the circular hole that can penetrate propellers, have the circular hole supporting with screw diameter on fixed ring sheet annulus, and rotating ring sheet both sides are provided with some boss, are equipped with propellers in the fixed ring sheet in screen drum and the interior ring of rotating ring sheet.
Evenly be provided with 4 screw rods between gripper shoe I and gripper shoe III, the fixed ring sheet has 4 circular holes in the position of corresponding screw rod.
Screen drum alternately is made of successively a plurality of fixed ring sheets and rotating ring sheet.Process boss on the both side surface of rotating ring sheet, when alternately assembling in groups with the fixed ring sheet, formed some bar grizzl(e)ies seams between every group of rotating ring sheet and fixed ring sheet, sieve seam quantity determined by the number of boss, and sieve seam width boss height is determined.
Described screen drum is provided with locating pad between every two fixed ring sheets, locating pad sheathed with screw rod on, locating pad is circular.Locating pad can make sieve seam width keep constant, avoid long-term high load capacity work to cause sieving the extension of seam, affect effectiveness of classification, guarantee that simultaneously the rotating ring sheet is subject to not being subjected to displacement vertically when helical blade drives between adjacent fixed ring sheet, and the rotating ring sheet radially can obtain desirable free activity space between locating pad.
Described screen drum also is provided with gripper shoe II between gripper shoe I and gripper shoe III, is provided with clamping screw between gripper shoe II and gripper shoe III, and clamping screw two ends are screwed with nut.The screw rod two ends are respectively equipped with double nut.Due to the work of the long-time high load capacity of screen cloth, the nut at screw rod two ends easily occurs loosening, is difficult to make the moving fixed ring sheet of each group that serial connection forms to compress, thereby causes equipment fault.Screw rod two ends are adopted pairs of anti-loose nut and be provided with clamping screw between gripper shoe II and gripper shoe III, avoided moving, fixed ring sheet group to become flexible at work.
Described spiral ore deep-graded sieve, the external diameter of propellers is greater than the internal diameter 5 to 10mm of rotating ring sheet, preferred 7mm.Because the external diameter of propellers is larger than the internal diameter of rotating ring sheet, helical blade continues in the process of driven ring plate internal rotating, under the effect of rotating ring sheet self gravitation, the helical blade outer always has a bit and contacts with the rotating ring plate inner surface, the rotating ring sheet will be according to the variation of the position that comes in contact and cycle movement between its moving havens, the changing of the relative positions constantly occurs in adjacent rotating ring sheet and fixed ring sheet simultaneously, has played the effect of automated cleaning compass screen surface, effectively prevents from sieving the generation of seam clogging.
Screen drum from feed chute to the discharge gate 15 ° of settings that are inclined upwardly.
Compared with prior art, the beneficial effects of the utility model are:
1. screen drum alternately is made of successively a plurality of fixed ring sheets and rotating ring sheet.Be processed with boss on the both side surface of rotating ring sheet, when alternately assembling in groups with the fixed ring sheet, formed 6 bar grizzl(e)ies seams between every group of moving, fixed ring sheet, sieve seam width boss height is determined, thereby is controlled the screening plant effectiveness of classification.
2. utilize the rotation with the propellers of helical blade, ore particles in feed chute enters the figure screen drum is travelled forward under the progradation of helical blade vertically produce the layered effect of similar " Brazil nut effect " process, be that ore particles forms bulky grain upper, granule under orderly distribution, increased the granule possibility of sieve thoroughly.
3. ore particles is in the process of tubular screen surface motion, and the sieve seam that consists of between the boss of granule on fixed ring sheet and the rotating ring sheet passes through, and the bulky grain of failing to sieve is discharged from discharge groove at last.Different product is reprinted, is collected respectively, realizes the process of classification.
4. when the rotating ring sheet is subject to the propellers driving, with the adjacent fixed ring sheet generation changing of the relative positions, make the position generating period variation of sieve seam in its free interval, both guaranteed tubular compass screen surface high opening rate and effectiveness of classification, avoided again sieve seam blockage phenomenon.
