Abstract

The invention discloses a pumping truss type suction dredger and a mounting method, and belongs to the technical field of sewage treatment. The pumping type truss suction dredger comprises a horizontal truss, and further comprises an end beam fixedly connected to the bottom of the horizontal truss, a steel frame and a mud scraping box; and a driving part used for driving the horizontal truss to move is arranged on the end beam; the steel frame is fixed at the bottom of the horizontal truss; the sludge scraping box is fixedly connected to the bottom of the steel frame; and sludge is guided through the sludge scraping box, so that the sludge is prevented from overflowing all around, the situation that the overflowing sludge is separated from the adsorption range of the suction dredger is avoided, and the sludge treatment effect is prevented from being reduced. The key in construction, namely, the construction method of the pumping type truss type suction dredger, is researched; a set of comprehensive construction technology for mounting the pumping truss type suction dredger is formed, the engineering quality is guaranteed, the reworking phenomenon is reduced, the engineering cost is saved, the mounting technology is simple, operation is convenient, and the engineering quality is easy to guarantee.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a pump-suction truss-type dredge and an installation method. Background technique [0002] With the rapid development of society, the recycling of urban domestic sewage and production wastewater is an increasingly urgent need for the social situation of increasingly scarce water resources; it is also an important measure to further improve regional environmental sanitation, reduce water pollution and protect the environment. Pump suction truss type Suction dredger is the core equipment of urban water treatment unit. [0003] In the prior art, when the dredger is processing the sludge at the bottom of the pool, the sludge often overflows to the surroundings in the pool, resulting in a reduced sludge cleaning effect, and the existing pump-suction truss-type dredge requires more labor for installation. , so the cost is higher, so it is necessary to design a pump-suction tr...
