Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering technology, and in particular to a sludge dewatering treatment device for river dredging. Background Technology

[0002] In the field of river management, river dredging and sludge dewatering equipment is a key piece of equipment for achieving the reduction and harmless treatment of river sludge. River dredging is primarily necessary because long-term accumulated sludge occupies river volume, reducing the river's flood control and drainage capacity. Simultaneously, the large amounts of pollutants and pathogens contained in the sludge can pollute water bodies, damage the aquatic ecosystem, and affect the production, lives, and ecological balance of surrounding residents. Therefore, dredging operations are needed to remove this sludge from the river. Solid-liquid separation of the dredged sludge is a crucial step in subsequent treatment and resource utilization. Its purpose is to separate the water from the solid sludge, reducing the volume and weight of the sludge, facilitating transportation, storage, or further processing, such as using the dewatered solid sludge for landfilling or soil improvement.

[0003] In existing technologies, filtration devices are commonly used for solid-liquid separation of dredged sludge. However, these devices have significant drawbacks, the most prominent being the tendency to clog the filter screen during filtration. Because river sludge has a complex composition, containing numerous fine particles, fibrous impurities, and colloidal substances, these materials easily accumulate on the filter screen surface during filtration. As filtration time increases, the pores of the filter screen gradually become clogged, leading to increased filtration resistance and requiring frequent shutdowns for cleaning or replacement. Furthermore, the device's self-cleaning and scraping capabilities are insufficient, increasing operating costs and labor intensity, and affecting the normal operation of solid-liquid separation. Additionally, the separation efficiency between sludge and liquid is relatively low, failing to adequately meet the needs of solid-liquid separation operations involving large quantities of sludge, and its ease of use is relatively limited. Therefore, we propose a river dredging sludge dewatering treatment device to address these issues. Utility Model Content

[0028] The extrusion separation hopper 6 is equipped with a filter and water removal screen 64, which can discharge water. The sludge is filtered and blocked by the mud removal filter screen 65. The driving component 8 can drive the liquid filter cover 7 to rotate, which makes it easy to clean and scrape off the dirt and sludge remaining on the surface of the filter and water removal screen 64 and the mud removal filter screen 65. It is easy to clean and not easy to clog.

[0029] The device has high mud-water separation efficiency, is easy to operate, has good self-cleaning and scraping effect of the filter screen, and is not easy to clog.

Running the cleaning motor 81 can drive the transmission disc 82, and then the transmission belt 83 can drive the other transmission disc 82 to clean the liquid filter cover 7, resulting in a good self-cleaning effect.

[0042] How to use and how to work this device:

[0043] By installing a solid-liquid separation pipe 2 and a drive motor 5 at the top of the processing platform 1, the drive motor 5 can drive the drive auger 4 inside the solid-liquid separation pipe 2 to rotate. The top of the solid-liquid separation pipe 2 is equipped with a feed hopper 3, and the sludge after dredging in the river can be poured into the feed hopper 3. The drive auger 4 inside the solid-liquid separation pipe 2 squeezes and guides the sludge to the squeeze separation hopper 6. Since the squeeze separation hopper 6 is conical, with the force of the drive auger 4 pushing and squeezing, the water source in the sludge can be squeezed out quickly. The water source is quickly discharged through the water outlet hole opened on the squeeze separation hopper 6. The sludge is discharged from the pipe of the squeeze separation hopper 6, thus completing the separation of sludge and water source. The sludge-water separation operation is relatively easy and the separation efficiency is relatively high.

[0044] The extrusion separation hopper 6 is equipped with a filter and dewatering screen 64, which can discharge water. The sludge is filtered and blocked by the sludge removal screen 65, which facilitates the discharge of water and the sludge filtration. At the same time as the mud and water are separated, the filter and dewatering screen 64 is equipped with a liquid filter cover 7. The running drive component 8 can drive the liquid filter cover 7 to rotate, which facilitates the cleaning and scraping of dirt and sludge remaining on the surface of the filter and dewatering screen 64 and the sludge removal screen 65. The cleaning is convenient and it is not easy to clog.

[0045] The side of the processing table 1 is provided with a liquid receiving basin 11, which facilitates the reception of water after mud-water separation.

When the pressure is high, the extrusion closing cover 63 can be opened to drain the soil. The sludge-water separation situation can be directly observed according to the pressure change. The filter water outlet 64 can squeeze out water during the sludge-water separation in the conical extrusion hopper 61. During the water discharge process, the sludge can be filtered by the sludge removal filter screen 65, making it difficult for soil to be discharged and resulting in good sludge-water separation effect.

The annular outer cover 71 is rotatably connected to the outside of the conical extrusion hopper 61 and sleeved on the outside of the filter water removal screen 64. When the annular outer cover 71 is driven by the driving component 8, it can drive the filter scraper 72 to quickly clean the mud and dirt remaining on the surface of the filter water removal screen 64 and the mud removal filter screen 65 to prevent clogging. The dirt inside can be discharged from the extrusion separation hopper 6 by the force of the driving auger 4, resulting in a good anti-clogging cleaning effect.

[0049] The drive unit 8 includes a cleaning motor 81, a transmission disc 82, and a transmission belt 83. The two transmission discs 82 are respectively connected to the output end of the cleaning motor 81 and the outside of the extrusion separation hopper 6.
