Abstract
The utility model discloses a kind of sieve bend even feeding case, belong to coal preparation equipment technical field.Technical scheme is: have manhole (1) side to be provided with feeding pipe (2) above casing (6), bottom is provided with discharging opening (7), in casing, feeding pipe top is provided with inclination stock guide (3), stock guide (3) can adjust angle, lower box has dashpot (8) and downflow weir (4), and weight (5) can adjust the angle of discharging.Good effect of the present utility model: the pan feeding situation of sieve bend is obviously improved, not only pan feeding is even, and material flow is all well controlled, and improves the de-mediated efficiency of sieve bend; Make sieve bend oversize evenly slowly enter vibration sculping screen, thus also improve the de-medium effectiveness of vibration sculping screen, reduce the consumption that is situated between, improve product quality.
Description
Technical field
The utility model relates to a kind of sieve bend even feeding case, belongs to coal preparation equipment technical field.
Background technology
In the hydrocyclone system washing process of coal preparation, material after cyclone process enters material collection case, then sieve bend feed box is entered, material is given on sieve bend by sieve bend feed box, first time de-mediated is carried out by sieve bend, qualified medium enters qualified medium bucket, and sieve bend oversize enters vibration sculping screen and carries out second time de-mediated.Because the feed of sieve bend feed box is uneven, cause sieve bend de-medium effectiveness poor, and sieve bend oversize enters the phenomenon that vibration sculping screen material also can produce skewness, also reduce the de-medium effectiveness of vibration sculping screen simultaneously, a large amount of medium powder is run off with the product of washing, not only cause the loss of medium, add coal washing cost, also have impact on the quality of coal preparation product.Cause the main cause of above problem to be that the feed flow velocity of sieve bend feed box is too fast and feed uneven, cause sieve bend and follow-up vibration sculping screen de-medium effectiveness poor.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model object is to provide one and makes sieve bend even feeding case, slows down feed flow velocity, and feed is even, solves the problems referred to above that background technology exists.
The technical scheme that the utility model adopts is: sieve bend even feeding case, contains feeding pipe, stock guide, manhole, discharging opening, dashpot, downflow weir, weight and casing, the top of casing is provided with manhole, there is feeding pipe side, bottom is provided with discharging opening, and in casing, the top of feeding pipe is provided with stock guide, the angle of stock guide can regulate, be provided with dashpot and downflow weir below stock guide, discharging opening is provided with weight, can adjust the feed angle of material.
Casing covers and is provided with manhole, can be used for observing pipeline and other positions of foreign material in feed situation, cleaning casing and maintenance box house, for preventing material from spilling, manhole is normal off status.
Material enters the utility model, and through too much stock guide, dashpot, after overflow edge and discharging opening, not only reduces the flow velocity of material, and make material evenly enter sieve bend from discharging opening, guarantee sculping screen best results, reduces the consumption of medium powder.
Good effect of the present utility model: the pan feeding situation of sieve bend obviously improves, not only pan feeding is even, and flow velocity is all well controlled, and makes material have the sufficient time to carry out de-mediated by sieve bend and vibration sculping screen; Improve de-mediated efficiency, reduce the consumption that is situated between; Sieve bend discharging opening feed angle can be adjusted by weight, applies more convenient; Feed box realizes integration, only need connect feeding pipe from outside, easy for installation; Equipment inner structure is simple, and disposable input is not high, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is that the utility model implements inside top structural representation;
In figure: manhole 1, feeding pipe 2, stock guide 3, downflow weir 4, weight 5, casing 6, discharging opening 7, dashpot 8.
Detailed description of the invention
Below in conjunction with accompanying drawing, by embodiment, the utility model is described further.
Sieve bend even feeding case, comprises manhole 1, feeding pipe 2, stock guide 3, downflow weir 4, weight 5, casing 6, discharging opening 7, dashpot 8.Feeding pipe has two and is fixed on body side, is divided into the pipe of little No. one of 4 diameters in casing.The top of casing is provided with manhole, and there is feeding pipe side, and bottom is provided with discharging opening, in casing, the top of feeding pipe is provided with stock guide, and the angle of stock guide can regulate, and is provided with dashpot and downflow weir below stock guide, discharging opening is provided with weight, can adjust the feed angle of material.
Casing covers and is provided with manhole, can be used for observing pipeline and other positions of foreign material in feed situation, cleaning casing and maintenance box house.For preventing material from spilling, manhole is closed condition.
Material enters the utility model, and through too much stock guide, dashpot, after overflow edge and discharging opening, not only reduces the flow velocity of material, and make material evenly enter sieve bend from discharging opening, guarantees the sieve best results that is situated between, reduces iron powder consumption.
Casing is metal weldedstructure part, material enters in case through feeding pipe 2, impact stock guide 3 homogenized, by stock guide 3, material is introduced dashpot 8, material flow is slowed down, through downflow weir 4, makes material be evenly distributed further, last uniform material enters sieve bend by discharging opening 7, and weight 5 can adjust the feed angle of discharging opening.
