Description

TECHNICAL FIELD

[0001] The utility model belongs to the equipment technical field of suction dredger, specifically a truss siphon type suction dredger. BACKGROUND

[0002] The siphon type suction dredger is a machine for horizontal sedimentation in sewage treatment plants and water supply plants. It is used to scrape the sludge settled at the bottom of the pool to the pump suction port for horizontal sedimentation in sewage treatment plants and water supply plants, and then to suck the sludge through the pump suction siphon type suction dredger to the edge of the pool, and then to discharge the sludge outside the pool, which can remove the sludge at the bottom of the pool.

[0003] The specific design and structure of the truss siphon type suction dredger may vary depending on different manufacturers and application requirements, but generally they include the following key parts: truss structure and siphon pipe, etc. The truss structure is usually made of section steel welding or bolt connection, with high strength and stability, which can span over the sedimentation tank to provide a support frame for the entire suction dredger. The siphon pipe is usually made of corrosion-resistant plastic or metal pipe, with one end deep into the sedimentation tank bottom near the sludge layer and the other end connected to the sludge discharge port or sludge collection device. The pipe diameter of the siphon pipe is selected according to the processing capacity of the suction dredger and the size of the sedimentation tank to ensure sufficient sludge conveying capacity.

[0004] In the traditional suction dredger, there are cases of unstable movement and limited movement range, which leads to the fact that the sludge in some areas of the sedimentation tank cannot be effectively sucked, and there are suction dead angles. Since the thickness of the sludge accumulation in the sedimentation tank and the working conditions are constantly changing, if the height of the suction part cannot be adjusted, the suction performance of the suction dredger may be affected under different sludge depths. During the working process of the siphon type suction dredger, the siphon branch pipe and the suction pipe are easily blocked by impurities, sticky substances or larger particles in the sludge. Once the pipeline is blocked, the suction amount of the sludge will decrease, and the suction speed will slow down, resulting in a significant decrease in the overall suction efficiency. SUMMARY
