Abstract
The utility model relates to a floating suction dredge, which comprises a buoy, a mud suction and discharge device and a transmission device. The utility model is characterized in that the mud suction and discharge device comprising a sucker and a mud pipe is fixed on the buoy which floats on the water surface of the mud sedimentation tank; the transmission device comprising a pulley, a winch and steel wires drives the suction dredge to do reciprocating motion under the control of the electric control system; mud sucked by the sucker is discharged outside the mud sedimentation tank by the mud pipe extending outside the mud sedimentation tank. The utility model has the advantages of light weight, low requirement for mud sedimentation tank, small driving power and simple structure, therefore can be applied to mud discharging of various mud sedimentation tanks.
Description
Technical field
The utility model relates to a kind of soil discharging facility, especially relates to a kind of suction dredger that is used for sedimentation basin of sewage disposal.
Background technology
Suction dredger is a kind of common equipment that is used for sludge from sedimentation tank in sewage treatment process, and at present, the pond type of settling tank mainly contains rectangle and two kinds of circles, and rectangle form pool mainly adopts the running type suction dredger, and the rotary type suction dredger is adopted in circular pond.The suction pipe of running type suction dredger is fixed on the crane span structure, and crane span structure is by wheel back and forth operation on the track on both sides, pond, is drawn in the sludge pipe back and discharges outside the pond by being deposited in mud at the bottom of the pond with the joining suction pipe of sump pump (or claim sludge pump).,, can be divided into two kinds of full-bridge type and semibridge systems again according to the difference of point of suppon.There is a point of suppon at center, full-bridge type pond, the crane span structure two ends respectively have a rubber tire to drop on the pool wall, the semibridge system point of suppon is at crane span structure one end, the other end drops on the pool wall by rubber tire, two kinds of forms all are that crane span structure is done turning motion, are drawn in the sludge pipe back and discharge outside the pond by being deposited in mud at the bottom of the pond with the joining suction pipe of sump pump (or claim sludge pump).For the rotary type suction dredger, be peripheral driven type by what rubber tire drove, be the center driven type by the point of suppon driving.
There is following defective in this suction dredger: 1. the structure of this suction dredger is because crane span structure is unsettled, and the span of crane span structure big (mostly being 10~20 meters), crane span structure will be born the moment of flexure that equipment on it and the weight of self produce, therefore himself higher intensity must be arranged, thereby the deadweight that causes crane span structure is big (being generally 5~10 tons), increased the consumption and the facility investment of material; 2. because the deadweight of this suction dredger is bigger, and its weight passes on the pool wall by wheel, the supporting capacity and the smooth degree of pool wall there is certain requirement, thereby has increased construction investment, and limited this kind suction dredger and only can be applicable to cement pit; 3. the running resistance of simultaneously this silt pumping car wheel is big, and required driving power is higher; 4. in addition, this suction dredger tool transmission rig is complicated, and operation and maintenance cost are higher.
Summary of the invention
For overcome in the prior art suction dredger weight big, settling tank requirement height, driving power are reached baroque deficiency greatly, the utility model provides a kind of floating type suction dredger.
Floating type suction dredger of the present utility model is achieved in that
Floating type suction dredger of the present utility model comprises suction mud device and transmission mechanism, and its maximum characteristics are that described suction mud device is fixed on the floating drum that floats on the mudpan water surface.
Above-mentioned suction mud device comprises sludge pipe and the suction pipe that is fixed on the floating drum, and wherein suction pipe is positioned at the bottom of mudpan, and the sludge pipe of Lian Tonging upwards passes the water surface and stretches to pond outside with it.
This suction dredger had both gone for the rectangle settling tank, back and forth moved along the settling tank long side direction, was driven by rope traction by the drive unit that is fixed on the settling tank minor face.In addition, this suction dredger also goes for circular settling tank, and this suction dredger can be the center with the circular settling tank, along settling tank circumferential direction rotating operation.
When above-mentioned mudpan was the rectangle settling tank, the control that described transmission mechanism is included in electrical control system drove reciprocating pulley, winch and the steel wire of this suction dredger down.
When above-mentioned mudpan also was circular settling tank, the control that described transmission mechanism is included in electrical control system drove rubber tire and the track that this suction dredger is made circumferential motion down.
The form that suction dredger of the present utility model can adopt pump to inhale also can adopt the form of siphon to discharge mud.Therefore above-mentioned suction mud device can also comprise the sump pump between sludge pipe and suction pipe, wherein suction pipe connects inlet, the sludge pipe connection sewage pump outlet of sump pump, sump pump is drawn into mud in the sludge pipe by suction pipe, by sludge pipe mud is discharged outside the settling tank.
According to service condition, suction dredger of the present utility model can be with Scraping device, also can not be with Scraping device.Therefore, above-mentioned suction mud device can also comprise the cleaning shoe that is positioned at the mudpan bottom.
Suction dredger of the present utility model is owing to come load capacity by floating drum, there is not heavy crane span structure, weight has only 1/3 of common suction dredger, equipment manufacturing cost can reduce near half, equipment is easier for installation, owing to do not need wheel on pool wall, to move, drive by rope traction, thereby can reduce weight of equipment and cost; Reduce simultaneously pool wall supporting capacity and planeness are required, greatly reduce the requirement to structures, the construction cost of structures can reduce by 30%, it can use in the native pond cheaply, be used with the floating type aerating apparatus that can in native pond, move equally, can reduce the cost of whole engineering significantly; The resistance of motion of the floating drum of this suction dredger in water also reduces much than the running resistance of wheel, thereby can reduce driving power; Simultaneously, do not need complex drive mechanism, thereby cost and operation and maintenance cost are all lower because this suction dredger only needs simple transmission mechanism.Be specially adapted to the sewage disposal of under-developed area, Midwest.
Description of drawings
Fig. 1 is the schematic top plan view of a kind of structure of the utility model.
Fig. 2 is the longitudinal section synoptic diagram of a kind of structure of the utility model.
Embodiment
To be used for rectangle settling tank pump suction type suction dredger be example, the utility model is described in further detail in conjunction with the accompanying drawings with a kind of below, and scope of the present utility model is not limited.Scope of the present utility model proposes in claims.
As depicted in figs. 1 and 2, floating drum 2 swims on the settling tank water surface, and the suction mud device of being made up of suction pipe 7, sump pump 8 and sludge pipe 3 is fixed on by steelframe 4 below the floating drum 2, and the suction inlet of suction pipe 7 is facing at the bottom of the pond, and sludge pipe reaches outside the sludge sump outward; Drive unit is fixed on the minor face of settling tank, floating drum 2 links with wireline 5, floating drum 2 is reciprocating by the control lower edge settling tank long side direction that is pulled in electrical control system of the towing mechanism be made up of wireline 5, pulley 1 and winch 6, the mud that precipitates is drawn in the sludge pipe 3 by suction pipe 7 by sludge pump 8, and is discharged to thus in the mud canal on settling tank side among Fig. 1.Thus, adopt the utility model suction dredger the mud in the settling tank can be discharged.
Wherein Fig. 2 elects Figure of abstract of the present utility model as.
