Description

Technical Field

[0001] The utility model specifically relates to the technical field of sludge treatment, in particular to a sludge treatment device for river channel cleaning. Background Art

[0002] When the water in the river flows, it will bring impurities such as mud from the upstream to the downstream. The impurities with larger mass will gradually settle in the water and eventually accumulate in the river. The river is wet all year round, so the impurities accumulated in the river gradually become silt. When there is too much silt, it will lift the river, reducing the amount of water in the river, or causing the water level in the river to rise. Therefore, it is necessary to lift up the silt in the river for cleaning.

[0003] Chinese patent announcement number CN 216236626 U discloses a sludge treatment device for river cleaning, which relates to the technical field of sludge treatment, and includes a device body, a sludge inlet pipe is connected to the middle of the top of the device body, and a first motor and a second motor are respectively installed on one side of the device body.

[0004] The above-mentioned sludge treatment device separates the water in the sludge by high-temperature evaporation and centrifugal force. However, the high-temperature evaporation method takes a long time and has a poor effect on separating the water in the sludge. In addition, the water in the sludge is thrown out by centrifugal force, and the weight of the sludge that needs to be centrifuged at one time cannot be too large, otherwise the bearing pressure of the centrifugal device will be too large, which will affect the centrifugal effect, making the sludge treatment efficiency of the above-mentioned sludge treatment device low.
