Technical Field
[0001] The utility model relates to the technical field of sludge cleaning, in particular to a river channel sludge cleaning device. Background Art
[0002] The organic matter and various mineral mixtures carried in the wastewater, after a long period of sedimentation, form sludge at the bottom of the water body. At the same time, the random dumping of domestic garbage and urban garbage brought by rainwater scouring are also important sources of river sludge. The accumulation of river sludge will not only cause the riverbed to rise, reduce the water-passing section of the river, and affect the flood discharge function, but may also cause secondary pollution to the water quality due to the pollutants accumulated in the sludge. Therefore, the cleaning of river sludge is particularly important. At present, the cleaning of river sludge is mainly carried out by sludge pumps. The sludge pumps use high-pressure water flow to flush the sludge at the bottom of the riverbed into mud, and the mud is pumped out through the pump body and discharged to a designated location for treatment;
[0003] Silt generally contains various debris. When the silt contains plastic bags and fishing nets, the mud inlet of the sludge pump is prone to blockage, and the existing sludge pump does not have a cleaning function.
[0004] In order to solve the above problems, a river silt cleaning device is proposed in the present application. Utility Model Content

[0011] Preferably, the annular pipe fitting includes a sleeve shaft, an assembly rod and an annular pipe body. The sleeve shaft is fixedly sleeved on the mud suction pipe. There are several assembly rods, one ends of which are respectively connected to the four sides of the sleeve shaft. The annular pipe body is sleeved on one end of the several assembly rods away from the sleeve shaft. One end of the water supply pipe is connected to the annular pipe body, and the end of the water supply pipe away from the annular pipe body is connected to a water pump.

[0014] The above technical solution of the utility model has the following beneficial technical effects:
[0015] By means of the filter element, flushing element and rotary cutting element, the sludge pump can be placed in the sludge for extraction. During the extraction process, the debris in the sludge can be filtered through the filter element at the bottom end of the sludge extraction pipe. In order to prevent the filter element from being blocked, high-pressure water can be guided to the annular pipe through the water supply pipe while the sludge is being extracted. Then, the high-pressure water is distributed to the corresponding flushing element through the annular pipe. The surrounding of the filter element can be flushed through the flushing element to prevent the filter element from being blocked. When the high-pressure water is discharged through the flushing element, the water flow can drive the rotary cutting element to rotate. When the rotary cutting element rotates, it can cut the plastic bags and fishing net lines in the sludge to prevent the debris in the sludge from adhering to the filter element. This structure can filter the debris entrained in the sludge during the sludge extraction process, and can prevent the filter element and the mud inlet end of the sludge pump from being blocked by flushing with water flow and cutting the debris, thereby maintaining the efficiency of sludge extraction.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0020] like Figure 1 and Figure 2 As shown, a river silt cleaning device proposed by the utility model comprises a sludge pump 1;
[0021] In this embodiment, the mud inlet end of the mud pump 1 is connected to the mud pumping pipe 2, and the bottom end of the mud pumping pipe 2 is connected to the filter element 3. The filter element 3 includes a sleeve 31 and a conical filter cartridge 32. A through threaded channel is provided in the sleeve 31, an external thread is provided at the bottom end of the mud pumping pipe 2, the sleeve 31 is threadedly sleeved on the bottom end of the mud pumping pipe 2, the conical filter cartridge 32 is connected to the bottom of the sleeve 31 and communicates with the threaded channel, and the outer periphery of the conical filter cartridge 32 is provided with densely arranged filter holes.
[0022] In this embodiment, an annular pipe fitting 4 is sleeved on the mud pumping pipe 2, and a water supply pipe 7 is connected to the annular pipe fitting 4. The annular pipe fitting 4 includes a sleeve shaft 41, an assembly rod 42 and an annular pipe body 43. The sleeve shaft 41 is fixedly sleeved on the mud pumping pipe 2, and there are a plurality of assembly rods 42. One end of the plurality of assembly rods 42 is respectively connected to the periphery of the sleeve shaft 41. The annular pipe body 43 is sleeved on one end of the plurality of assembly rods 42 away from the sleeve shaft 41. One end of the water supply pipe 7 is connected to the annular pipe body 43, and one end of the water supply pipe 7 away from the annular pipe body 43 is connected to a water pump.
[0023] In this embodiment, the bottom of the annular pipe member 4 is connected to a plurality of flushing members 5 arranged around the filter element 3. The flushing member 5 includes a flushing pipe 51, which is connected to the bottom of the annular pipe body 43 and arranged circumferentially around the conical filter cartridge 32, and the bottom ends of the flushing pipes 51 are connected to a fixing block 52, and the sides of the bottom ends of the flushing pipes 51 are connected to a flushing nozzle 53 arranged toward the conical filter cartridge 32.
[0024] In this embodiment, the bottom of the flushing member 5 is rotatably connected with a rotating cutting member 6. The rotating cutting member 6 includes a rotating rod 61, which rotates through the fixed block 52 and extends into the flushing pipe 51, and an axial flow blade 62 located at the end of the flushing nozzle 53 is installed at the top of the rotating rod 61, and a plurality of circumferentially arranged blades 63 are installed at the bottom of the rotating rod 61.
[0025] It should be noted that the sludge pump 1 can be placed in the sludge for extraction. During the extraction process, the conical filter cartridge 32 at the bottom of the sludge extraction pipe 2 can be used to filter the debris in the sludge. In order to prevent the conical filter cartridge 32 from being blocked, the water supply pipe 7 can be connected to the water pump while the sludge is being extracted.
