Description

Technical Field

[0001] The invention relates to the technical field of sludge aging and stacking, in particular to a brick-burning sludge processing device with a screening function. Background Art

[0002] The main function of the sludge aging bin is to promote the full penetration of the mixture of sludge and clay during the aging process, so as to prepare for the subsequent granulation and shaping process. Specifically, the aging bin allows the moisture and chemical components between the sludge and clay to be fully mixed and penetrated through an aging process of 7-14 days, ensuring the uniformity and stability between the materials. The sludge aging bin reduces the moisture content in the sludge to a certain level through natural volatilization and biaxial stirring, and fully mixes it with the clay. The mixed materials are sent to the aging warehouse for long-term aging, during which physical and chemical changes will occur between the materials, further enhancing their uniformity and stability;

[0003] The role of sludge aging bin in sludge treatment. Sludge aging bin plays a vital role in the sludge treatment process. It ensures that the mixture of sludge and clay reaches the best physical and chemical state before entering the granulation shaping process, thereby improving the quality and efficiency of granulation. In addition, the aging process can also improve the physical properties of sludge, making it more suitable for subsequent treatment and utilization.

[0004] At present, when sludge is transported to the aging bin, it is usually transported to the bin by a forklift and stacked. This stacking method not only requires a large enough operating space, but also the stacking height of the forklift is limited, resulting in a waste of space inside the aging bin. In addition, the sludge is stacked by forklift transportation, so that the sludge that does not meet the particle diameter requirements cannot be screened.
