12 inch cutter suction dredger is a ship widely used in dredging engineering. It uses the front end of the suction pipe to install a rotary reamer device around the suction pipe to cut and stir the river bottom sediment, and then through the suction pipe, the twisted sediment material is transported to the mud with the help of powerful pump suction. Sand stockpile. Its dredging, mud transporting, mud unloading and other work can be completed continuously, with high efficiency and low cost. It is a good underwater excavating machine.
Performance characteristics of 12 inch cutter suction dredger:
- Wide range of uses. It can be used in rivers, lakes and seas for dredging, channel excavation, and land reclamation. In special cases, high-power reamer equipment is installed on the 12 inch cutter suction dredger, and rock formations such as basalt or limestone can be excavated without blasting.
- High working efficiency, large output and long pump distance. The output of large 12 inch cutter suction dredgers can reach thousands of cubic meters per hour, and the sediment or rock materials are pumped thousands of meters away through mud pumps and mud discharge pipelines with strong power.
- Simple operation and easy control. The dredger relies on the trolley at the stern to position and step the steel pile, uses the steel cables on both sides of the cutter arm frame and the anchors fixed on both sides of the excavation groove, is pulled by the winch, and the hatchback swings and cuts the sediment material. Working under the control of the swing angle, the twisted material is pumped to the accumulation yard through the mud pipe. The stepping of the dredger is to move forward alternately by two piles.
- The large 12 inch cutter suction dredgerhas a self-propelled system, which can be self-propelled in place during migration. Most of the small and medium dredgers have no self-propelled system and are towed by tugboats. Small and medium-sized dredgers can be designed to be assembled, transported to the site by land, and can be used after assembly.
- Good economy. The excavation and transportation of materials are completed without the need for other ships to cooperate with several times of handling, and the relative engineering cost is relatively low.
This equipment is a full hydraulic transmission cutter suction type, suitable for dredging operations in rivers, lakes and reservoirs. The whole equipment is assembled, and when the equipment is transferred over a long distance or operated in unconnected waters, it can be disassembled and transported by land. When passing through bridges and other height-limited places, the cab can also be disassembled separately.
The 10-inch pump 12 inch cutter suction dredger in our workshop was delivered to Russia. The customer used it for dredging locally. We designed the entire assembly line. Starting from the customer’s 12 inch cutter suction dredger pumping sand in the river, the sand is discharged to the shore through the pipeline. This 10-inch pump cutter suction sand pump is also the second sand pumping equipment purchased by the customer. Last year, the customer ordered a small jet suction sand pump for experimentation. The effect is good, but with the increase of sand pumping depth, encounter There are also many stones in the mud layer, so a 12 inch cutter suction dredger must be selected for work! At present, our 12 inch cutter suction dredger is designed according to the working environment of the customer.
This 10-inch pump 12 inch cutter suction dredger is designed to pump down to a depth of 12 meters, and the sand discharge distance can reach 500 meters. Since the customer’s project in Russia has begun to take shape and the electrical facilities are complete, the customer chooses to use the motor with lower cost in the later use as the main power. Our design is to use a 220KW motor to drive a 10-inch sand pump. The post-use cost of the whole ship will be lower than that of diesel engines, saving nearly half. Please see the detailed configuration of the ship:
- Hull design:
The hull is a three-body design, with the engine room in the middle and side floats on both sides (at the same time, the side floats are also a two-body structure, which is convenient for transportation)
Main cabin 12m*3.2*1.5m, side floating body 19m*1.2*1.5m (two groups)
Bottom plate 8mm, side plate 6mm, panel 5mm anti-skid plate
- Power and sand pump
Main engine 220KW-6 motor
Motor 30KW——drive the horizontal paddle
Sand suction pump – 10 inches, flow 1100 cubic meters
- Reamer
The diameter of the reamer is 1200mm, made of wear-resistant alloy, and the teeth can be replaced. Hydraulic motor torque reaches 24000N.M
- Hydraulic pump station
Including hydraulic oil tank, solenoid valve, hydraulic winch, hydraulic pipeline, etc.
- Others
Two heels of fixed piles, operating room, engine room, lighting system, etc.
