Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering technology, specifically to a sludge dewatering device. Background Technology

[0002] To improve the quality of family life, people cultivate and decorate with horticultural plants in indoor spaces, balconies, rooftops, and courtyards. Plants purify the air by fixing carbon and releasing oxygen. Planting containers are an indispensable part of this process, and currently, most are made of plastic or ceramic clay. However, plastic containers have poor air permeability and are not environmentally friendly, while ceramic clay containers are costly and energy-intensive. As a result, an ecological planting container has emerged. This type of container is made from river and lake silt and agricultural waste as raw materials. It can reuse the silt generated during the excavation of rivers and lakes, which has the advantages of being ecological and environmentally friendly. At the same time, it uses natural raw materials, which are more similar to the characteristics of nutrient soil and are conducive to plant cultivation.

[0003] When using river and lake sludge for container preparation, dewatering pretreatment is required. The commonly used dewatering method is filter press. In a closed filter chamber, a high-pressure pump applies pressure to the flocculated sludge, and the sludge is dewatered by squeezing through the filter cloth. Existing sludge filter press dewatering equipment requires shutdown to remove the sludge after dewatering, which affects efficiency and is inconvenient to use.
