Problems solved by technology

However, when the mud discharge slope is relatively large, if the dredger stops digging in the relay pump system, the pump station stops, or the system suddenly stops operating for some reason (including an accident), the mud pipe on the slope will cause dredging. The mud flows back, forming the mud recoil in the relay pump pipeline and damaging the relay pump system

Embodiment 1

[0033] figure 2 It is the mud pool scheme for station selection and climbing in the remote series relay pump system of the present invention. The remote series relay pump system can make the backflow mud flow into the mud pool in each section of the relay mud pumping station, and then transport the mud to the mountain for filling.

[0034] The dredger 1 is connected to the first mud pump station (ship) 3 through the first mud discharge pipe 2, the outlet of the first mud pump station (ship) 3 is connected to the entrance of the second mud discharge pipe 4, and the second mud discharge pipe The outlet of 4 is connected to the inlet of the second mud pumping station 5, and the outlet of the second mud pumping station 5 is provided with a first check valve 12, and a first explosion-proof bypass piping system is arranged in front of the first check valve 12, and the first check valve 12 is provided. An explosion-proof bypass pipeline system is composed of the first explosion-pro...

Embodiment 2

[0061] image 3 It is the reverse flow scheme for station selection and climbing in the remote series relay pump system of the present invention. The remote series relay pump system can reverse the flow of mud into the excavation area of ​​the dredger through the joint action of the multi-stage mud return pipe and the mud discharge pipe.

[0062] The dredger 1 is connected to the first mud pumping station (ship) 3 through the first mud discharge pipe 2, and a first check valve 12 is provided at the outlet of the first mud pumping station (ship) 3, and the first check valve 12 There is a first explosion-proof bypass piping system in front, the first explosion-proof bypass piping system includes a first explosion-proof valve 15 and a first mud return pipe 14, and the mud flowing out from the first mud return pipe 14 can directly flow back to the dredger opening. digging area.

[0063] The first check valve 12 is connected with the inlet of the second mud discharge pipe 4 at th...

Abstract

The invention relates to a conveyer device in a dredging process, in particular to a remote serially-connected booster pump station system used for conveying mud via a booster pump station provided with a dredge. The remote serially-connected booster pump station system comprises a dredge, a dredge pipe and a mud pump station; the dredge pipe and the mud pump station are connected in series; the remote serially-connected booster pump station system further comprises a mud pump station control system; a check valve is arranged at the exit of the mud pump station; and an anti-explosion valve bypass piping line is arranged before the check valve. Through the arrangement of the check valve, the anti-explosion valve bypass piping line and the related control system, the booster pump station system can prevent the mud from flowing back and kicking back and is particularly suitable for climbing for the remote serially-connected booster pump station system; moreover, the booster pump station system is safe and reliable.

Description

technical field [0001] The invention relates to a conveying device in dredging, in particular to a remote relay pumping station system for conveying mud through a relay pumping station with a dredger. Background technique [0002] The system of multiple relay pumps connected in series includes local series (close series) and remote series; the former only uses a few meters long pipeline to directly connect the outlet of the previous mud pump with the suction of the latter mud pump; the latter connects the two pumps in series The distance between the mud pumps is hundreds of meters or thousands of meters, and the relay pumps are connected in series in the middle. This kind of remote series connection has many advantages, which makes the pressure distribution of the entire pipeline relatively uniform, so the remote series connection relay pump system is widely used. [0003] In order to transport mud remotely, several mud pumps are connected in series with mud discharge pipes ...
