Using method for movable riverway sludge dredging device

Abstract

The invention relates to a using method for a movable riverway sludge dredging device. According to the technical scheme, a movable hull and the sludge dredging device are included, a sludge agitator and a double-capacity mixer are used to fully mix the sludge at the bottom of a river with the river water to make the mixture into sewage, a suspending hammer at the front half part of the double-capacity mixer crushes the bulk material which is stirred out at the bottom of the river, and then a soft material such as a plastic bag or a rope is cut by a suspending slicing piece at the rear half part of the double-capacity mixer, so that the generated small-particle sewage is transported to a sewage storage tank in the form of fluid and then is pumped into the sludge treatment tank on the movable hull under the pumping action of a sewage pump for treatment, and the circulating water is sprayed to an inlet of the double-capacity mixer to drive the sludge into the double-capacity mixer to form a circulation. The using method has the beneficial effects that the riverway can be smoothly cleaned, the ecological impact on the riverway is very small, a lot of man-hours can be saved, and the serious influence on the use of the riverway and the traffic is unlikely; and in addition, compared to an existing dredging device, by the adoption of the using method, the efficiency is higher and the cleaning is thorough.

Description

technical field [0001] The invention relates to a sludge dredging device and method, in particular to a method for using a mobile river sludge dredging device. Background technique [0002] At present, in the dredging of the river channel, the method often used is: firstly block the original river channel, then drain the water in this section of the river channel, and finally use mechanical methods to clean it up. use. In this way, it is not only time-consuming and labor-intensive, but also has a serious impact on the ecological system in the river. At the same time, sometimes for the safety of construction, it is necessary to temporarily close the traffic line adjacent to the river, which seriously affects the traffic in the corresponding section. ; and this method does not apply to large rivers. [0003] The Chinese patent document publication number is 207749557U, and the patent title is "A kind of dredging equipment for river silt", which includes a hull and a dredging...

AI Technical Summary

Problems solved by technology

The existing problem is: use the movement of the hull to drive the scraper forward to scrape the river bottom silt into the scraper box, the river bottom is not flat, there may be not only a mud layer, but also a rock layer, so the scraper is not necessarily Can achieve the purpose of the invention of the patent

The existing problem is that the dredging device is installed on the slider on the fixed device through a cross bar, the dredging device moves left and right along the fixed device, and the fixed device is installed on the bank of the river, such a dredging device cannot be applied to large rivers Medium, only suitable for small rivers, can be fixed on the bank

The existing problems are: the adopted silt pumping device is mainly driven by the submersible motor to drive the winch, and then the silt is sucked onto the hull through the suction pipe. Firstly, this process causes the silt in the river channel to be muddied as a whole, seriously affecting the normal life of the organisms in it. Survival destroys the natural ecology; the second is that the reamer can only cut it into fragments when encountering rock layers, and the fragments cannot be sucked into the hull by the straw, so the rock layers or large stones cannot be dredged out, it cannot meet the needs of the site; moreover, without underwater positioning, the bottom of the river cannot be cleaned evenly and smoothly

The existing problem is: the underwater silt is directly transported to the hull under the crushing and guiding action of the claw knife and the ultrasonic vibrator, and there is still the problem that the gravel cannot be sucked out to the hull; The bottom cannot be cleaned evenly and flatly; although, considering the uneven softness and hardness of the bottom silt in the dredging environment and the instability of the equipment center caused by wind and waves in water surface operations, an unbalanced adjustment structure is designed, using buoys and semi-enclosed The rotating buoy matches the structure to balance the gravity of the front dredging mechanism and the instability caused by suction. When the equipment is tilted, the semi-enclosed rotating buoy can quickly respond to deflection around the movable bearing, changing its own draft, and the fuselage It maintains a level under the action of its own gravity to achieve the stability of the equipment operation process; however, it does not guarantee the smooth operation of the bottom of the water

[0007] In short, the existing river channel silt dredging devices cannot effectively process and dredge the rock layers or large stones that appear at the bottom of the river. The existing technology is for simple crushing, but the stones cannot be further processed into small stones or smaller size that can be sucked
