Description

Technical Field

[0001] The utility model relates to the technical field of sludge cleaning devices, in particular to a sludge cleaning device for water conservancy project construction. Background Art

[0002] During the construction of water conservancy projects, a lot of silt will appear inside the river channel. In order to prevent the silt from accumulating in the river channel for a long time and affecting the normal drainage of the river channel, it is necessary to clean the silt inside the river channel regularly. At this time, silt cleaning agencies are needed to clean the silt.

[0003] After searching, Chinese patent CN213741299U in the prior art discloses a river channel silt cleaning device for water conservancy project construction, including a ship plate, wherein the surface of the ship plate is respectively provided with a sludge suction hole and a water screening hole, and the upper surface of the ship plate is respectively fixedly connected with a hydraulic telescopic rod and an auxiliary limiting sleeve, the number of the hydraulic telescopic rods is two, and the telescopic end of the hydraulic telescopic rod is fixedly connected with a mounting plate, the surface of the mounting plate is provided with a sludge suction hole, the inner wall of the sludge suction hole is fixedly connected with a sludge suction pipe, and the top of the sludge suction pipe is fixedly connected with a three-way connecting pipe. The utility model utilizes the arrangement of a ship plate, a mounting plate, a sludge suction pipe and a sludge suction pump to suck out the sludge in the river channel, and by arranging a sludge discharge pipe, a screening bucket and a filter net, the sucked out sludge can be contained, and the filter net can be used to filter the river water in the sludge, thereby reducing the weight and volume of the sludge, avoiding the river water occupying the position in the bucket, and improving the load-bearing capacity of the device.

[0004] However, during the sludge suction period of the utility model sludge cleaning device, some sludge will adhere to the inner wall of the pipe. If it is not cleaned, the sludge will dry and adhere to the inner wall of the pipe for a long time, which not only reduces the diameter of the inner wall of the pipe, but also reduces the efficiency of sludge suction. At the same time, during the filtration of sludge and river water, the lack of a stirring mechanism makes it difficult to separate the river water and the sludge, and the natural separation efficiency is relatively low, which cannot meet the production needs. Therefore, a sludge cleaning device for water conservancy project construction is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problem that some sludge will adhere to the inner wall of the pipe. If it is not cleaned, the sludge will dry and adhere to the inner wall of the pipe for a long time, which not only reduces the diameter of the inner wall of the pipe, but also reduces the efficiency of sludge suction. At the same time, during the filtration of sludge and river water, there is a lack of a stirring mechanism, which makes it difficult to separate the river water and sludge, and the natural separation efficiency is relatively low.

[0015] Compared with the prior art, the utility model provides a sludge cleaning device for water conservancy project construction, which has the following beneficial effects:

[0016] 1. The sludge cleaning device for water conservancy project construction absorbs the sludge and discharges it into the inner side of the filter screen through the sludge suction pump.
