Abstract
The utility model relates to a feed box for realizing uniform distribution of feeding material of an arc-shaped sieve and belongs to the technical field of coal preparation and processing equipment. The technical scheme adopted by the feed box is that a feed opening (1) is formed in the upper part of a box body (9); a discharge opening (8) is formed in the lower part of the box body (9); a porous separating plate is arranged below the feed opening, below which a grid plate (2) is arranged; an inclined material guide plate (4) is arranged below the grid plate; and an adjustment plate is arranged at the discharge opening and is provided with an adjustment rigging (6) in a matched manner. The feed box has the positive results that the feeding condition of the arc-shaped sieve is greatly improved; not only is the feeding uniform, but also the flow and flow rate are well controlled, and accordingly non-pressure feeding of the arc-shaped sieve of a washing and sorting system of a swirler is realized, and the materials have abundant time for medium draining through the arc-shaped sieve; and the materials entering a vibration medium draining sieve are low and uniform, thereby avoiding quick splashing phenomenon which in turn ensures excellent medium draining of the vibration medium draining sieve and reduces medium consumption.
Description
Technical field
The utility model relates to a kind of sieve bend pan feeding material feed box that evenly distributes, and belongs to the coal washing technical field of processing equipment.
Background technology
In the cyclone system washing process of coal washing processing, when the underflow (or overflow) of cyclone directly enters underflow case (or spill box), enter the sieve bend feed box again, material enters on the sieve bend through the sieve bend feed box, carry out the de-mediated first time by sieve bend, qualified medium enters the native system circulation, and the sieve bend oversize enters the vibration sculping screen and carries out the de-mediated second time.The mixture of the underflow of cyclone (or overflow), underflow case (or spill box) through cyclone enters the sieve bend feed box, because the skewness of material, cause the reduction of sieve bend task performance, de-mediated weak effect, directly cause the sieve bend oversize to enter vibration sculping screen material skewness, also reduced the de-mediated effect of vibration sculping screen simultaneously, a large amount of media (iron powder) just mix loss with washing smalls without abundant de-mediated, cause the loss of medium, improved the coal washing cost.Consumption continues high because coal washing is situated between, the part of outbalance was the feed box transformation of cyclone washing system sieve bend during reduction Jie consumption improved equipment, because sculping screen de-mediated effect is not very desirable in the cyclone washing system always, and the reason of influence vibration sculping screen de-mediated is the too fast and feed inequality of feed flow velocity of top sieve bend, cause sieve bend de-mediated effect relatively poor, make that also material splashed when material entered the vibration sculping screen, be difficult to reach good de-mediated effect.
The utility model content
The utility model purpose provides a kind of sieve bend pan feeding material feed box that evenly distributes, and improves cyclone washing system sieve bend feed effect, slows down the feed flow velocity, and feed is even, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: the sieve bend pan feeding material feed box that evenly distributes, comprise charging aperture, flase floor, porous demarcation strip, inclination stock guide, adjust plate, adjust with rigging, discharging opening and casing, the top of casing is provided with charging aperture, the bottom is provided with discharging opening, in casing, is provided with the porous demarcation strip below the charging aperture, be provided with flase floor below the porous demarcation strip, be provided with the inclination stock guide below the flase floor, discharging opening is provided with the adjustment plate, and adjusting the plate coupling has the adjustment rigging.
Described flase floor is provided with grate opening.
Cover on the described casing and be provided with peep hole, so that observe feed situation, the interior foreign material of cleaning casing.
The underflow of cyclone (or overflow) directly enters underflow case (or spill box), enter the utility model again, through porous demarcation strip, flase floor, inclination stock guide with after adjusting plate, the material of reuniting is scatter enters the vibration sculping screen in uniform way, guarantee to vibrate the sculping screen best results, reduce iron powder consumption.
Good effect of the present utility model: the pan feeding situation of sieve bend obviously improves, not only pan feeding is even, and flow and flow velocity all be well controlled, and realized that cyclone washing system sieve bend does not have the material of being pressed into, thereby made material have the sufficient time to carry out de-mediated by sieve bend; The material that enters the vibration sculping screen is not only evenly slow, and the phenomenon of not splashing fast, thereby has guaranteed the good de-mediated of vibration sculping screen, having reduced the consumption that is situated between; The pan feeding of the uniform feed box of sieve bend pan feeding material is not awarded the position influence of material point, uses more convenient; Save the expense of changing spare part, reduced maintainer's labour intensity; The disposable input of equipment is not high, and maintenance of equipment is simple, and consumes energy not.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model embodiment A-A sectional structure schematic diagram;
Among the figure: charging aperture 1, flase floor 2, porous demarcation strip 3, inclination stock guide 4, adjustment plate 5, adjustment rigging 6, grate opening 7, discharging opening 8, casing 9.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further by embodiment.
The sieve bend pan feeding material feed box that evenly distributes, comprise charging aperture 1, flase floor 2, porous demarcation strip 3, inclination stock guide 4, adjust plate 5, adjust with rigging 6, discharging opening 8 and casing 9, the top of casing is provided with charging aperture, the bottom is provided with discharging opening, in casing, is provided with the porous demarcation strip below the charging aperture, be provided with flase floor below the porous demarcation strip, be provided with the inclination stock guide below the flase floor, discharging opening is provided with the adjustment plate, and adjusting the plate coupling has the adjustment rigging.
Described flase floor is provided with grate opening 7.Cover on the described casing and be provided with peep hole, so that observe feed situation, the interior foreign material of cleaning casing.
The underflow of cyclone (or overflow) directly enters underflow case (or spill box), enter the utility model again, through porous demarcation strip, flase floor, inclination stock guide with after adjusting plate, the material of reuniting is scatter enters the vibration sculping screen in uniform way, guarantee to vibrate the sculping screen best results, reduce iron powder consumption.
Casing is a metal weldedstructure spare, the material of reuniting enters in the case through charging aperture 1, through grate opening 7 backs of porous demarcation strip 3 and flase floor 2 by progressively evenly, pass through inclination stock guide 4 more again by further even, last material uniformly enters the sieve bend casing through adjustment plate 5 and discharging opening 8, adjusts with rigging 6 set for the aperture of control material discharging opening adjustment plate.
In the present embodiment, the sieve bend sheet changed 3 times in original one month, changed 1 time in one month behind employing the utility model, be example only, economized 1.4 ten thousand yuan in one month, can economize 16.8 ten thousand yuan in 1 year with a sieve bend, certain coal washery cyclone system has 12, and it is up to a million to economize fund in 1 year.
