The section of the dredging tube is in the shape of the inclined rectangle, and the upper end of the dredging tube is conical, so that a phenomenon that sludge accumulated on the upper part of the dredging tube is stacked to carry out an anaerobic reaction is avoided.
Description
Technical field
The utility model relates to field of sludge treatment in sedimentation basin, is specially a kind of center-transmission single-pipe suction dredger.
Background technology
Suction dredge is generally key equipment in secondary sedimentation tank, is widely used in the eliminating of sedimentation basin precipitating sludge.
Center-transmission single-pipe suction dredger is mainly comprised of parts such as service bridge, drive unit, central post, collection mud cylinder, dredging tubes.Centre-driven device drives rotation in Xi Nijia pond, and dredging tube is suspended to be inhaled mud and spread out under frame and be connected with collection mud cylinder, relies at the bottom of inside and outside water-head ，Jiang pond, pond activated sludge to suck and collects mud cylinder, outside discharge pond during rotation.Surface skimmer device is collected liquid level scum silica frost to scrape to the deslagging bucket of pool side and is discharged outside pond.
Suction dredge in the course of the work, is failed optimal design due to dredging tube, and dredging tube often can not be inhaled mud fast, equably, causes mud to overflow across dredging tube top and causes and pile up or miss dredging tube, causes that part mud stops for a long time, causes long-pending rotten; Before dredging tube is inhaled mud, mud does not directly suck in dredging tube through liquefaction (appropriate disturbance), increases acting head loss, is difficult for carrying.
Utility model content
The purpose of this utility model is for above-mentioned defect, provides a kind of suction mud smooth and easy, even, guarantees without long-time mud accumulation, disturbance minimum, the simultaneously higher single-tube suction dredge of collection efficiency.
The technical scheme that realizes above-mentioned purpose is: a kind of center-transmission single-pipe suction dredger, it is characterized in that: comprise the rotating collection mud cylinder that is arranged on sedimentation basin center, the dredging tube that one side seal of collection mud cylinder connects, the opposite side of collection mud cylinder and the position of dredging tube symmetry are connected with counterweight frame, and described dredging tube is at sedimentation basin Di Rao pond central rotation; Center, Ji Nitong upper end is provided with vertically disposed central post, at the bottom of the lower end of central post is passed down through collection mud cylinder and is fixed on sedimentation basin, central post is equipped with dredging tube truss outward, the lower end of dredging tube truss is fixedly connected with collection mud cylinder, the top of dredging tube truss is provided with service bridge, one end of service bridge is fixedly connected on the upper end of dredging tube truss, the other end of service bridge is supported on sedimentation basin edge, on service bridge, be provided with the drive unit that drives dredging tube truss to rotate, the below of service bridge is provided with the skimmer device of installing by support.
Optimally, the cross section of above-mentioned dredging tube is the rectangle being in tilted layout, and the edge of the cross section of described dredging tube from the center of sedimentation basin to sedimentation basin dwindles gradually, is provided with mud-suction hole on dredging tube.
Optimally, above-mentioned dredging tube is formed by connecting by multistage, on every section of dredging tube, be provided with the equal mud-suction hole of equal and opposite in direction, spacing being evenly arranged, mud-suction hole from the center of sedimentation basin to each section of dredging tube at the edge of sedimentation basin diminishes gradually, mud-suction hole is arranged on the bottom of dredging tube, the bottom of dredging tube is provided with cuts mud plate, for cutting pool bottom sludge.
The beneficial effects of the utility model: the cross section of dredging tube of the present utility model is the rectangle being in tilted layout, and upper end is tapered, prevent from being deposited in the mud accumulation on dredging tube top, and anaerobic reaction occurs.
Mud-suction hole of the present utility model, over against the mud that will inhale collection, makes the mud that will inhale collection have a suitable initial velocity to mud suction mouth.
Dredging tube of the present utility model is divided into multistage, and the mud-suction hole footpath of section and section not etc., can not regarded the hydraulic condition in change section ,Bian aperture, varying head all the time as approx during dredging tube spoil disposal.Guaranteed that in dredging tube, mud flow velocity is even, prevented that aperture from stopping up and the interior sludge settling of pipe.If aperture is size equally, that is larger the closer to flow in core dredging tube, and flow velocity is certainly lower, easily causes the obstruction of mud extraction, sedimentation.
The bottom of dredging tube of the present utility model is provided with cuts mud plate, and for cutting pool bottom sludge, mud, before being sucked into mud-suction hole, is cut mud plate to cut, and has increased the mobility of mud, reduces the loss of flood peak, guarantees accurately, promptly the mud of precipitation is absorbed.Can guarantee, without long-time settled sludge, long-pending rotten few, to improve biologically active, reduce biological tank oxygen-supplying amount, and prevent that in mud, phosphate discharges and sludge bulking floating.Improve returned sludge concentration simultaneously, reduce reflux ratio, can reduce the aeration rate in aeration tank simultaneously.After mud-suction hole, there is liquefaction plate to be used for mud to liquefy.Can evenly absorb mud.
