Description

Technical Field

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

[0002] River dredging generally refers to the management of rivers, which is a water conservancy project. When there is less silt, mechanical equipment is used to blow the silt deposited on the riverbed into turbid water, which flows away with the river water, thereby playing a role in dredging. When there is more silt, an excavator or a mud pump is needed to discharge the silt from the river, and then the silt is dehydrated and reused through a dehydration device.

[0003] After searching, the patent number "CN217556042U" mentioned in the text that "the utility model provides a high-pressure filter pressing and dehydration device for river sludge treatment, which belongs to the technical field of river sludge treatment devices, including an accommodation box; the bottom of the high-pressure device is fixedly connected to the accommodation box; the bottom of the auxiliary filtering device is fixedly connected to the accommodation box; the water filtering mechanism is slidably installed inside the auxiliary filtering device; the utility model is provided with a water filtering mechanism and an auxiliary filtering device inside the device, which can quickly filter and dehydrate the top surface of the sludge, and can also assist in rapid filter pressing and dehydrating the inside of the sludge." It filters the sludge through a filter cloth, but in actual use, the sludge itself has a certain viscosity. After high-pressure squeezing, it is easy to stick to the filter cloth, causing the filter cloth to be blocked and unable to discharge the mud and water normally, so that the mud and water are sucked back by the sludge again after the squeezing is completed, resulting in the sludge dehydration cannot be completed normally. At the same time, the sludge often loses fluidity after squeezing and cannot be automatically discharged from the device normally.

[0004] To this end, we provide a dewatering device for river sludge cleaning to solve the above problems. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Through the setting of the sedimentation component, the muddy water squeezed out of the sludge will flow directly into the first sedimentation tank, and then flow into the second sedimentation tank again. At the same time, the muddy water is filtered through the first filter screen and the second filter screen, and then a secondary sedimentation is performed to reduce the content of debris and sediment in the muddy water and improve the purity of the discharged muddy water;

After the silt enters the dehydration box, the extrusion controller is started to control the hydraulic push rod to extend, and the silt in the dehydration box is squeezed and dehydrated through the extrusion plate.

When the mud pushing plate is cleaning the sludge, the scraper plate at its bottom will scrape the bottom of the dewatering box. At the same time, the mud on the dewatering filter will be brushed and cleaned by the hard-bristle mesh brush to prevent the silt from clogging the dewatering filter and ensure the dewatering effect of the silt. In this way, after the silt is squeezed and dehydrated, the silt can be automatically discharged from the dewatering box. At the same time, the dewatering filter in the dewatering box can be scraped and cleaned to prevent the silt from sticking to the dewatering filter and affecting the dewatering effect. At the same time, the mud water is filtered and precipitated to reduce the content of mud and sand in the mud water, thereby improving the overall use effect of the device.
