Truss Siphon Suction Dredge

Abstract

The invention discloses a truss siphoning type suction dredger which comprises a machine frame transversely arranged in a sedimentation tank, a siphoning device installed below the machine frame and driving mechanisms arranged at two ends of the machine frame.A flow adjusting mechanism connected with the siphoning device is further arranged on the machine frame.The siphoning device comprises a main siphoning pipe, a sludge suction pipe and a plurality of groups of suction branch pipes communicated with the main siphoning pipe and the sludge suction pipe, and multiple sludge suction ports are formed in the sludge suction pipe.The flow adjusting mechanism comprises a plurality of pull rods and blocking cylinders arranged at the lower ends of the pull rods, and multiple adjusting parts for adjusting flows are arranged on each pull rod.A limiting frame for limiting the flow adjusting mechanism is arranged on the machine frame.The truss siphoning type suction dredger utilizes water in the sedimentation tank and water in the main siphoning pipe to form a water level difference, further can directly suck sludge at the bottom of the tank into the main siphoning pipe, accordingly discharges the sludge into the main siphoning pipe, avoids the phenomenon that pump blockage is easily produced in the mode that a dredge pump is adopted to directly suck sludge, and improves the working efficiency.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a truss siphon type dredger. Background technique [0002] The truss suction dredger is one of the commonly used mechanical sludge removal devices for sedimentation tanks. It is widely used in the drainage of advection sedimentation tanks and inclined tube (plate) rectangular sedimentation tanks for sludge removal. It is characterized by working back and forth, sucking mud while walking, little interference to sludge, simple equipment structure, and convenient operation and management. [0003] The current truss type suction dredger generally includes a frame, an electric control device, a mud collection device, a mud suction device, a driving device, etc., and the electric control device, the mud collection device, and the mud suction device are all driven by the driving device, and its working principle is Use the submersible pump to pump out the air in the siphon pipe to form ...

AI Technical Summary

Problems solved by technology

[0004] At present, in the truss type suction dredger, there is no adjustment device to control the suction flow. At the same time, in order to ensure that the submersible pump can move with the truss, the connection between the submersible pump and the siphon piping system is mostly connected by steel pipes. When the submersible pump needs maintenance Or when maintaining or replacing, it is necessary to cut the steel pipe connecting the submersible pump and the siphon pipeline system, and take out the submersible pump. Because it is connected by a steel pipe, it is difficult to take out the submersible pump, which increases the labor intensity of the operator, wastes time, and reduces work efficiency.

Moreover, it is also difficult to discharge the mud accumulated in the inclined pipe. It is necessary to empty the pool manually and flush it with a high-pressure water gun. The work efficiency is low.
