It is interior.
The top surface in the vacuum sludge treatment cabin sets closure, and the through hole is provided with the closure.
The present invention technical concept be:To reduce moisture content, so as to reduce mud total amount, it is also necessary to entering the mud behind cabin
Handled again.It is more difficult using existing frequently-used centrifugal dehydration technology aboard ship because mud is rich in water in itself, the present invention
Fast dewatering processing is carried out to mud using vacuum drainage concretion technology.After mud enters application of vacuum cabin, the mud into cabin
Insert multigroup vertical drainage pipe, the spacing between vertical drainage pipe to be advisable no more than 800mm, through seal cover board after pass through water
Flat pipe is directly accessed vavuum pump, such as accompanying drawing 2.Vacuum drainage processing is implemented to mud in cabin, handled by high intensity Quick drainage
Afterwards, mud can reach the vehicle-mounted degree do not dripped, and be sent to through conveyer belt and entruck and carry away on the bank.
For excavated in training of channel engineering it is inefficient in sludge process and cause river bed harmful substance to water body again
Pollution, the present invention using pumping with machine dig be combined by the way of, by bed-silt control in the range of river bed, do not make to turn over thereon and
Water body is mixed, and inhales excavation method using submersible, i.e., slips into the digging head of mud in bed-silt, and spiral shell is carried out using mechanical system
Rotary rod type excavates mud, while negative pressure air is connected in screw rod, on the one hand can reduce the mud of rotary mining process to
Outer diffusion, mud is limited near spiral mining head, on the other hand can improve the lifting speed of mud, using this latent
Excavation method, it can also reduce water body and be excavated into mud in body, the overall accumulated amount of mud be reduced from digging end, as shown in Figure 1.
Beneficial effects of the present invention are mainly manifested in:1st, by vacuum dehydration technology application dredger, it is auxiliary to establish vacuum
Help the sludge treatment ship for excavating and being combined with silt vacuum dewatering;2nd, the excavation of mud and processing procedure are realized by sensor
The real-time control of processing, improve the efficiency of sludge treatment.

It is discharged into river course.
A set of Centralizing inspection control system is also set up on ship, lays underwater camera under water, reflects submerged digging feelings in real time
Condition, the vertical propulsion of mining head, the starting of chain mat machine, rising and falling for vertical drainage pipe support uses hydraulic pressure centralized Control.Mud is true
Empty dewater treatment is controlled by discharging water, and water ga(u)ge is installed in drainpipe, is discharged water by calculating, is determined mud
The reduction situation of water content, it can stop handling when mud water content is less than less than 50%, circulation is handled next time.
Specific embodiments of the present invention are as follows:
Above-mentioned technical scheme need to be adjusted according to Practical Project condition in specific implementation process, below as general
Engineering specifications brief description specific embodiment.
1) ship of the present invention is opened to river course, lake where engineering, to engineering specifications, the main depth of water including river course, become silted up
Mud thickness, pollution condition are adjusted on the spot, and carry out tentative excavation according to pre-determined arrangement and method for construction, so as to further
Examine the depth excavated and excavate form.
2) underwater camera is opened, setting takes mud depth, mining head casing is transferred to muck surface, can use latent
Enter depth h=200mm, decentralization spiral mining head to muck surface, open hydraulic drive valve, reach and take mud depth to retreat to silt automatically
Mud surface, when silt depth is small and softer, horizontal excavation form can be set, reaching need not retract after taking mud depth, keep deep
Degree directly horizontal promote takes mud.
3) while mining head starts to take mud, vavuum pump is opened, and spiral excavates and negative pressure air is connected in axle, negative pressure in axle
Being maintained at -50kPa is advisable, and can adjust negative pressure force value according to the size of mud exit water is taken, can be appropriate when water yield is big
Negative pressure absolute value is reduced, otherwise can suitably be increased, the water that do not suck in river course as far as possible;Also it can be observed and dug by underwater camera
Streamflow regime around pick head casing is adjusted, and pressure should be reduced when obvious flowing in the current direction mining head of casing periphery,
Whereas to suitably increase pressure.
4) treat that (mud suction cabin 13 can use with vacuum sludge treatment cabin 14 in the mud in mud suction cabin 13 close full cabin
Identical volume of compartment amount) when, the hatch door between mud suction cabin 13 and vacuum sludge treatment cabin 14 is opened, opens chain mat machine 17, will be true
Fill mud and close hatch door between two cabins in empty sludge treatment cabin 14;If mud water content is larger, when can not be completely filled up, can first close
Hatch door is closed, recycles dredge pump to inhale mud from mud suction cabin 13 and fills vacuum sludge treatment cabin 14.
5) mud water content w in vacuum sludge treatment cabin 14 is quickly determined, decentralization vertical drainage pipe support, compresses sealed compartment
Lid, vavuum pump breather valve and draining valve are opened, open water flow measurement sensors and mud face droop sensor, started vacuum and take off
Water;Vacuum dehydration pressure is maintained at -90kPa, and sealing dewatering time is by the water rate control discharged, when handled mud water content
During less than 50%, it is believed that mud can have vehicle to be transported, and vacuum dehydration processing can stop, and can also count as the following formula
Calculate and determine.
(abHw-Q)/ab(H-H1)<0.5
In formula, a, b and H are the length physical dimension in vacuum mud cabin, and w is the moisture content into cabin mud, and Q is vacuum
The water of pump discharge;H1For the consolidation deflection of mud in vacuum mud cabin.
6) hatch door between mud cabin 16 to be shipped after vacuum sludge treatment cabin 14 and dewater treatment is opened, opens chain mat machine, will
Mud cabin 16 to be shipped is to be shipped after mud after application of vacuum is delivered to dewater treatment;Close at vacuum sludge treatment cabin 14 and dehydration
Hatch door after reason between mud cabin 16 to be shipped, the hatch door between mud suction cabin 13 and vacuum sludge treatment cabin 14 is opened, is carried out
The vacuum of subsequent cycle mud departs from water process.
