Abstract

The utility model relates to a straw (veneer) water washing machine, which is mainly suitable for washing and purifying straws steamed in pulping paper-making industry. Two steel pipes with the same diameter intersect each other to form a Y-shaped structure; antislip strips are welded on the inner wall of pipes; one screw shaft is fixed in each pipe, and the transmission end is arranged on the upper end of the screw shaft; the screw shaft is driven by a speed reducing electric motor; a dreg storage pipe and a dreg discharge system are arranged on the lower end of the screw shaft. The straws and the water are added in the upper part of an inlet pipe at the same time, and the straws (veneers) are pushed down to a discharge pipe by a feed screw; weights subside under the choosing and separating action of water, and the straws (veneers) float upward and go against a flow of purified water to strengthen the washing action; a slapping rod is used for peeling off dregs; the straws (veneers) are pushed up above the liquid surface by a discharge screw and thrown out by discharge blades, then water washing operations are completed.

Description

Blade (wood chip) rinsing machine

The utility model relates to a kind of being used for the blade after machine cut (wood chip) is carried out the pulping and paper-making industry special equipment that weights such as removing its earth that is mingled with, sandstone, metal are used in the continuous washing operation.

At present this type of device of using of domestic manufacturer mostly is from the product of external introduction and the Counterfeit Item of domestic production, and such device is used to wash the drum-type that is of wood chip, be used to wash blade for centrifugal, both function singlenesses can not dual-purpose.Especially wash leather sheet device, complex structure big because of floor space, moving consumption is big, accident rate is high, this class device washing quality is low in addition, operating cost is high, can not satisfy industrial production and require and be difficult to promote.

The purpose of this utility model is: a kind of waterpower wash mill that is used for the blade after machine cut (wood chip) is implemented high wash degree is provided.The moving consumption of the utility model is low, simple in structure, floor space is little, simple to operation, process adjustments is strong, operating cost is low.

The purpose of this utility model is achieved in that the steel pipe that two certain diameters (being decided by production capacity) are uneven in length becomes " Y " font to intersect, and is welded with the many tread plates that evenly vertically distribute on the inner tubal wall.Two driving ends are inserted in respectively in the long and short two arm at last cantilever screw rod.Long tube is a discharge nozzle, and short tube is a feed pipe.Washings are injected continuously by top, and the bottom has drainpipe to link to each other with balanced reservoir.Sheet material moves to the discharge nozzle lower end from top to bottom with injecting water in the lump in the access to plant of feed pipe upper end under the promotion of feed auger, weight sank to two pipe bottoms, intersection and regularly discharged this moment.Blade (wood chip) floats less than water because of proportion and injects water with discharge nozzle top and is the back flushing state, no spiral shell leaf on the discharging spiral lower end axle and knock bar along circumferentially being welded with, beat and stir constantly come-up flushing continuously of blade (wood chip), after sheet material rises to certain altitude, the spiral shell leaf of discharging spiral is left the water it, behind the flowable water that elimination is not absorbed by blade (wood chip) by discharge blade with its centrifugal dishing out from the discharging opening of discharge nozzle side, thereby finished whole laundry operation.

Such scheme is addressed its design feature: this device has utilized the choosing branch effect of water and the back flushing effect of water fully; The great advantage that this device is different from external product is that the weight that is mingled with in the blade (wood chip) not only can effectively separate, and can not damage device, realized this best washing process process of countercurrent washing that inlet device can't be finished simultaneously, because this device has made full use of the characteristic of water, therefore it is simple in structure, and moving consumption is low.

The utility model concrete structure provides with following embodiment and accompanying drawing thereof:

(figure one) is blade (wood chip) rinsing machine artwork

(figure two) are blade (wood chip) rinsing machine profiles

Among the figure: 1, blade (wood chip) water washing device; 2, adjustable water level balance water tank; 3, aqua storage tank; 4; Centrifugal water pump; 5, centrifugal pulp cleaner; A, feed pipe; B, discharge nozzle; C, feed auger; D, discharging spiral; E, charging aperture; F, discharging opening; G, drive sprocket; H is by movable sprocket; I, bearing utmost point motor bearing; J, reducing motor; K, water injection pipe; L, remove the balanced reservoir drainpipe; M, slag storage tube; N, slag-discharging valve; O, tread plate; P, knock bar; Q, discharge blade; R, helical blade

In (figure one), water adds from blade (wood chip) rinsing machine charging aperture continuously with the blade (wood chip) that contains weight impurity, and pushed when coming downwards to the discharge nozzle of blade (wood chip) water washing device (1) by the spiral shell leaf along axis, big impurity continues descending with water and sinks to the row for the treatment of in the slag storage tube, tablet is under buoyancy, float along the discharge nozzle axis, and with descending water generation countercurrent washing, discharging spiral lower end ring Zhou Junbu knocks bar, impact blade (wood chip) and strengthen washing, make fine impurities from blade (wood chip) sur-face peeling, with walking to the row for the treatment of in the slag storage tube under water.Blade (wood chip) floats when the back is pushed into the discharge height vertically by discharging spiral (D) to liquid level, and the centrifugal force that rotation produces by load displacing screw is discharged from the discharge nozzle exit.Water level is transferred to adjustable water level balance water tank (2) by communicating pipe with sewage and adjusts the purpose that the overflow valve of this balance can play adjustment and control blade (wood chip) water washing device water level in the device; Overflow water flows into aqua storage tank (3) reuse again after centrifugal water pump (4) is sent into centrifugal pulp cleaner (5) to remove weight impurity.In (figure two), represented is the concrete structure of blade (wood chip) water washing device.Feed pipe (A) and discharge nozzle (B) intersect " Y " font, and are welded in the phase cross surface and to be one.There is being spiral (R) position inwall circumferentially equidistantly to be welded with tread plate (O).Respectively putting one in feed pipe (A) and the discharge nozzle (B) is located by motor bearings bearing (I); , stud with and stud with helical blade (R) bottom in the middle of the discharge blade (Q) and stud with respectively one on the discharging spiral that knocks bar (P) by drive sprocket (G) and by reducing motor (J) but pre-rotation studs with the feed auger (C) of helical blade (R) and top by movable sprocket (H) transferring power.Quilt is washed blade (wood chip) and flushing water enters in the feed pipe (A) from discharging opening (E) in the lump, when feed auger is rotated, being washed blade (wood chip) is admitted in the discharge nozzle along axis is descending, and choosing divides back weight impurity to sink to entering slag storage tube (M) and regularly discharged by slag-discharging valve (N).The last warp float discharging spiral of blade (wood chip) pushes when going upward to discharge blade (Q) position is dished out from discharging opening by centrifugal force.Water inlet pipe (K) is used to inject washings, and drainpipe (L) is delivered to adjustable balanced reservoir with wash water.
