Description

Technical Field

[0001] The utility model belongs to the technical field of river channel desilting and dredging, and particularly relates to a mobile flushing device for a vibrating screen of an aquatic silt conditioning ship. Background Art

[0002] Ecological dredging is a key technical means to solve the pollution problem of rivers, lakes and reservoirs. Its core advantage lies in its ability to effectively remove polluted sediments, thereby reducing the release of endogenous pollutants and further improving the water ecological environment. However, in actual application, due to the high water content of sludge and the high transportation cost, the large amount of sludge generated during dredging operations can only be dumped in the form of abandoned soil in the area around the dredging area for natural or artificial dehydration. This practice not only occupies a large amount of land resources for a long time, but also may cause secondary pollution during the long-distance transportation of sludge, bringing additional burden to the environment.

[0003] With the increasing and recurring demand for dredging, the land resources required for local sludge treatment are becoming increasingly scarce. This problem has become more and more urgent and has become an environmental problem that needs to be solved urgently. In order to meet this challenge, an innovative equipment platform came into being, and its publication number is CN117509945A. The equipment platform integrates sludge conditioning vessels, sludge conditioning vessels, filter press volume reduction vessels and residual water treatment vessels, realizing an integrated process of water operations, greatly improving the efficiency and processing capacity of dredging operations.

[0004] Specifically, the sludge conditioning ship is responsible for collecting and transporting sludge, and the sludge conditioning ship removes impurities and regulates the sludge through advanced impurity removal and conditioning systems. Subsequently, the sludge is transported to the filter press volume reduction ship for further screening, impurity removal and dehydration and volume reduction. The filtered mud cake can be transported out through mud barges, effectively avoiding the pollution of sludge to the water body and solving the problem of land occupation in sludge treatment.

[0005] The silt slurry sucked up by the dredging vessel is screened by the vibrating screen of the sludge conditioning ship to remove large particles of debris, and the remaining slurry is further processed and utilized; after screening for a period of time, debris will adhere to the surface of the vibrating screen, causing the sieve holes of the vibrating screen to be blocked. The current treatment method is to manually flush the vibrating screen with a high-pressure water pipe at intervals. The flushing process increases the labor burden and has low efficiency.

[0029] In order to make the objectives, technical solutions and advantages of this utility model more clear and understandable, the following further details this utility model in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not used to limit this utility model.

[0030] Refer to Figures 1 to 3 , a movable flushing device for a vibrating screen of an aquatic sludge conditioning vessel, which is movably arranged on the top surface of the vibrating screen of the sludge conditioning vessel. For the convenience of installation, through holes with the same length are opened on both sides of the frame 1 of the vibrating screen of the sludge conditioning vessel, and the guide rail 8 of this device is placed in the through holes and welded or bolted to the frame 1.

[0031] This device further includes a movable chassis 10, and the movable chassis 10 is arranged in a symmetrical structure and includes connecting beams 9 respectively arranged on both sides. Both ends of the connecting beam 9 are respectively rotatably connected with rollers 4; the rollers 4 are driven by a motor to drive this device to reciprocate on the vibrating screen so as to flush the surface of the vibrating screen.

[0032] Support beams 5 are respectively arranged on the connecting beam 9. The support beam 5 is arranged obliquely to the vibrating screen surface, and the inclination angle forms an angle of 50 degrees to 60 degrees with the connecting beam 9. The inclined arrangement of the support beam 5 is conducive to reducing the length of the flushing branch pipe 3 and lowering the overall height of the device.

[0033] The top end of the support beam 5 fixedly supports a main flushing pipe 7, and the main flushing pipe 7 is communicated with a high-pressure water source; a number of flushing branch pipes 3 are communicated with the main flushing pipe 7, and the number of the flushing branch pipes 3 is determined according to the width of the vibrating screen; the flushing branch pipes 3 are arranged to incline downward, and the included angle between the flushing branch pipe 3 and the support beam 5 is set to be 50 degrees to 60 degrees. The inclined arrangement of the flushing branch pipe 3 towards the vibrating screen surface is beneficial to the high-pressure water sprayed by the flushing branch pipe 3 to impact the vibrating screen surface obliquely, thereby improving the cleaning efficiency.

[0034] A nozzle 6 is arranged at the end of the flushing branch pipe 3; further, the nozzle 6 is set as a rotating nozzle, and the rotating nozzle enables the flushing to have no dead angle and improves the cleaning efficiency of the vibrating screen surface.

[0035] Further, the guide rail 8 is set as a U-shaped groove structure, and the U-shaped groove is used to accommodate the roller 4 to roll therein; it is used to provide guidance for the operation of the device.

[0036] The working process of the utility model: The silt slurry sucked by the cutter suction dredger is screened by the vibrating screen of the silt conditioning ship to remove large-particle sundries, and the remaining slurry is further processed and utilized; after the vibrating screen is screened for a period of time, sundries will adhere to the surface, resulting in the blockage of the vibrating screen holes. The current treatment method is to flush the vibrating screen with a high-pressure water pipe manually at intervals for a period of time. The flushing process increases the manual burden and has low efficiency.

[0037] After adopting this device, the initial position of this device is at the higher end of the vibrating screen. The high-pressure water source is regularly turned on, and the control motor of the roller 4 is turned on. This device runs forward along the guide rail 8 while flushing the vibrating screen. The flushing method from high to low is more conducive to the cleaning of the vibrating screen surface; after the flushing is completed, the high-pressure water is turned off, and the motor drives the roller 4 to drive this device to return to its position; after adopting this device, the flushing efficiency of the vibrating screen is improved and the flushing has no dead angle.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
