Turtle type pump dredge

Abstract

The invention relates to a turtle type pump dredge. The turtle type pump dredge is characterized in that the middle part of the dredge is provided with a displacement type slurry pump, a material distributing machine is fixed at the front part of the dredge, and the material distributing machine comprises a bracket, a supporting arm and a dredge pipe; a bench rack which can rotate for 360 degrees is arranged on the rack, the bench rack is connected with a folding supporting arm, the dredge pipe is fixed on the supporting arm and the lower end of the dredge pipe is connected with the outlet of the displacement type slurry pump. The turtle type pump dredge has the advantages: firstly, the slurry transmitted has high concentration with the solid-to-liquid ratio of 80 percent, the water precipitation time is decreased, dredge field is not needed and the thick slurry can be directly loaded into tank vessels and transmitted, thus avoiding the secondary pollution; secondly, the transmission distance is long and can usually come up to 1,000-2,000m; and thirdly, the turtle type pump dredge can run in marsh, shoals and inland rivers and lakes in cities to dispose the domestic garbage and industrial wastes in cities.

Description

Technical field [0001] The invention belongs to water conservancy dredging, and specifically refers to dredging equipment. Background technique [0002] There are about 3.7 billion m in our country every year 3 Most of the sediment enters the sea, most of which are deposited in the estuary area and the coasts on both sides, causing the continent to expand continuously to the sea, forming coastal beaches and swamps. In addition, when the sediment enters the sea, a large amount of siltation is formed in rivers and channels, leading to flood For this reason, the state invests heavily in river dredging and management every year. However, the current cutter suction, bucket wheel, and trailing suction dredgers in China all use centrifugal mud pumps. The dredging methods of these machines have the following disadvantages: First, the mud concentration is low, generally between 10% and 30%. It is necessary to have a suitable mud yard; otherwise, the return of sewage will cause secondary p...

Problems solved by technology

However, at present, the cutter suction, bucket wheel and trailing suction dredgers in China all use centrifugal mud pumps. The dredging methods of these machines have the following disadvantages: First, the mud concentration is low, generally between 10% and 30%. A suitable mud discharge site is required; otherwise, the backflow of sewage will cause secondary pollution to the surrounding areas; the second is that conventional cutter suction or bucket wheel dredgers cannot handle dredging in urban rivers, lakes and reservoirs. Domestic and industrial waste, such as bricks, stones, woven bags, old shoes, etc., so that construction can not be done, only manual dredging
