Specific implementation mode
Fig. 1 to Fig. 3 shows a specific embodiment of this cutter suction dredger of the application, about for processing capacity
3500m3Large-scale twist of/h inhales ship.Identical with traditional dredger to be, which also includes hull, and hull is provided with：Inhale mud
Mouth 6, dredge pump, the reamer on the outside of mud suction mouth being connected with mud suction mouth.Wherein, reamer includes：Reamer wheel hub 1, reamer circle 2,
More reamer arms 3 being connected between reamer wheel hub and reamer circle are provided with numerous cutters tooth 4 on reamer arm 3.1 He of reamer wheel hub
Reamer circle 2 is coaxially arranged and in axially-spaced certain distance, and reamer arm 3 is helical structure, and each reamer arm 3 is along week
To uniform arrangement.
The key improvements of the present embodiment are, the reamer of cutter suction dredger is changed to five arms by six traditional arm reamers
Reamer, i.e. reamer arm 3 are provided with five and the unconventional six roots of sensation altogether, and five arm reamers are relative to six traditional arm reamers, between tool arm
Away from bigger, the generation of clay package reamer head phenomenon is reduced, while enhancing the passability of block stone, clay, improves construction
Efficiency.Also, anti-stone ring 5 is welded between each reamer arm 3, the anti-stone ring 5 of installation can twist large volume block stone and clay gear
Outside knife, prevent large volume block stone and clay from blocking mud suction mouth and dredge pump.
Above-mentioned anti-stone ring 5 is circular ring structure, and anti-stone ring 5 and reamer wheel hub 1 and 2 three of reamer circle are coaxially arranged.And
And anti-stone ring 5, altogether there are two settings, the spacing of the two anti-stone rings 5 and the spacing of each reamer arm 3 are of substantially equal, make anti-stone ring with
Reamer arm constitutes the mudstone channel of approximating square.
Moreover, the cutter tooth 4 on reamer arm 3 is wearability cutter tooth, wear-resistant material is used to cast, folder is excavated so as to reduce
The abrasion of stone flint clay has extended bridge and has changed tooth time interval (tooth number is changed in reduction), increased time availability.
In addition, the present embodiment has also been welded with anti-stone grid 7 in mud suction mouth 6, anti-stone grid 7 can pass through reamer to accident
Strip block stone is refiltered, and the probability that large volume block stone enters dredge pump is further decreased.
Obviously, anti-stone grid 7 can't block mud suction mouth 6 completely, and multiple mudstones, which have been collectively formed, with mud suction mouth 6 passes through
Mudstone channel.Naturally, anti-stone ring 5 will not block reamer completely, mudstone is also formed between anti-stone ring 5 and reamer arm 3
Channel.In the present embodiment, the mudstone channel formed by anti-stone grid 7 and mud suction mouth 6 is slightly larger than by 3 shape of anti-stone ring 5 and reamer arm
At mudstone channel (area in single mudstone channel).
As shown in figure 3, in the present embodiment, above-mentioned mud suction mouth 6 is arc-shaped structure, and anti-stone grid 7 is by along mud suction mouth 6
Spaced apart more grille strips are constituted length direction successively, and the length of grille strip is set along the radial direction extension of mud suction mouth 6
It sets.Also, the radial width of the spacing and mud suction mouth 6 of adjacent two grille strip is essentially identical.
In addition, the above-mentioned dredge pump that the present embodiment also pair twist inhales ship is transformed, which is powerful efficient dredge pump,
Diameter is shorter, impeller spacing bigger, can be effectively increased the percent of pass of mud and reduce dredge pump oil consumption.The big passability of efficient dredge pump
Keep strand suction ship more smooth to the conveying of flint clay with high-power, increases concentration of hydraulic mixture, reduces plugging probability.
When excavating horsestone flint clay using this cutter suction dredger of the present embodiment, can be used different construction parameters into
Row examination is dug, to obtain optimal construction parameter.It is dug by examination, it has been found that:The control of reamer rotating speed is in 20~25rad/min, traversing
Speed control pump diesel speed control in 8~10m/s, underwater and cabin exists in 960~1000rad/s, the control of reamer pressure
10~15MPa, the control of traversing pressure pump row pressure control in 5~10MPa, submersible pump vacuum control in 40%~60%, cabin and exist
0.95~1.05MPa, flow control 5.3~5.8m/s, concentration control below 20%, submersible pump electromechanics flow control is 190
When~200A is constructed, effect is preferable.
Moreover, in excavating work progress, if there is reamer pressure and the case where traversing pressure increases suddenly, can determine whether
Clay packet reamer phenomenon has occurred, in this regard, first reamer is carried out to wash away dredging using clear water, such as still unresolved, then bridge of having stopped work,
By manually removing packet reamer clay.If there is the case where vacuum increases, row pressure reduction and flow velocity reduce, can determine whether to be inhaled
Mud mouth blocks or dredge pump clogging, in this regard, first mud suction mouth and dredge pump are carried out washing away dredging using clear water, it is such as still unresolved,
It has then stopped work bridge, by manually removing the block stone for blocking mud suction mouth and the block stone for blocking dredge pump.If there is row pressure to increase and flow velocity
The case where reduction, can determine whether that sludge pipe plugging phenomenon has occurred, then carry out block part dredging by way of tearing pipeline open.
Certainly, above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to make people much of that
Solution present context is simultaneously implemented according to this, and the protection domain of the application can not be limited with this.It is all according to the application major technique
The equivalent transformation or modification that the Spirit Essence of scheme is done, should all cover within the protection domain of the application.
