Description

Technical Field

[0001] The utility model relates to the technical field of anti-splashing of sludge feeding, in particular to a device for preventing splashing of sludge feeding. Background Art

[0002] During industrial wastewater treatment, sludge is produced through solid-liquid separation. This sludge is then transported via dump trucks through a discharge port. This sludge typically contains 40-60% water. During discharge, it comes into contact with the truck bed and easily splashes out of the truck bed, which does not meet clean production requirements. This requires workers to clean the surrounding area, increasing labor intensity. While these issues can be addressed through technical improvements such as reducing the water content or upgrading solid-liquid separation equipment, these improvements are time-consuming and require system downtime, making them difficult to achieve in a short period of time. To address these issues, a sludge discharge anti-splash device is proposed. Summary of the Invention
