Siphon type suction dredge

Abstract

The invention relates to a siphon type suction dredge. The siphon type suction dredge comprises a working bridge, guide rails, a driving device, sludge suction nozzles, underwater sludge suction pipes and overwater sludge discharge pipes, wherein the working bridge stretches across the guide rails; and the driving device is arranged on the working bridge. The innovation is that: the bottom of a pool is provided with a plurality of transverse sludge suction pipes which are connected with the underwater sludge suction pipes and the overwater sludge discharge pipes, the tail ends of the overwater sludge discharge pipes are connected into a water sealing cylinder, and the overwater sludge discharge pipes are also connected with a vacuum-pumping system; and a plurality of sludge suction nozzles are arranged on each transverse sludge suction pipe, and a rhombic scraper is arranged between the adjacent sludge suction nozzles. The working bridge does reciprocating motion along the guide rails; after the vacuum-pumping system is started, sludge enters the transverse sludge suction pipes, the underwater sludge suction pipes and the overwater sludge discharge pipes through the sludge suction nozzles under negative pressure, and then falls into the water sealing cylinder; the sludge is divided toward two sides and is pushed to positions in front of the sludge suction nozzles by utilizing the forward movement of the rhombic scrapers, so that the sludge suction nozzles can suck the sludge conveniently, and the siphon type suction dredge has a good sludge suction effect; and meanwhile, the resistance when the working bridge moves forwards is reduced, so that the power and energy consumption of the driving device can be correspondingly reduced.

Description

technical field [0001] The invention relates to a siphon type dredge machine, in particular to a siphon type dredge machine with small walking resistance and good mud suction effect. Background technique [0002] The siphon suction mud machine is used for advection sedimentation in sewage treatment plants and waterworks. It scrapes the sludge settled at the bottom of the pool to the suction port, sucks the mud while walking, and then discharges the sludge out of the pool to remove and clean the sludge at the bottom of the pool. suffering. The siphon suction dredger consists of a working bridge, a dredging pipe, a dredging pipe, a driving mechanism, an electric control box, guide rails and a submerged dredging pump. The traditional mud scraper is a flat plate structure that is close to the bottom of the pool. The working bridge has great resistance during the movement process, and when the mud scraper scrapes the mud, the sludge is tightly accumulated on the front of the mu...

Problems solved by technology

The traditional mud scraper is a flat plate structure that is close to the bottom of the pool. The working bridge has great resistance during the movement process, and when the mud scraper scrapes the mud, the sludge is tightly accumulated on the front of the mud scraper, and the mud suction nozzle cannot absorb mud smoothly. The mud suction effect is not good, and maintenance is inconvenient
