Description

Technical Field

[0001] This utility model relates to the field of tap water treatment technology, and in particular to a retention device applied to the sedimentation tank of a tap water plant. Background Technology

[0002] Existing interception devices used in sedimentation tanks of water treatment plants consist of a tank and internal filter components. After adding flocculants to the sedimentation tank, tiny particles in the water will agglomerate into larger flocs. The interception device can intercept these flocs, making the settled water clearer and greatly reducing suspended particles and impurities in the water. If these impurities enter natural water bodies, they may affect the water's transparency, hinder the photosynthesis of aquatic organisms, and thus have an adverse impact on the aquatic ecosystem.

[0003] However, during its use, it lacks a cleaning component that can continuously clean the filter plates during the interception process to remove solids from the filter plate surface. Solid impurities easily accumulate on the filter plates, causing them to become clogged. This reduces the speed at which water flows through the filter plates, affecting the working efficiency of the sedimentation tank. After the filter plates become clogged, they need to be manually disassembled and cleaned or replaced, increasing maintenance costs and workload. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a retention device for sedimentation tanks in waterworks. During retention, the arc-shaped scraper scrapes the solids on the surface of the filter plate into the transfer box, ensuring that the filter plate remains relatively clean and improving filtration efficiency. Then, the solids are pushed to the sludge storage box for storage through the sludge discharge pipe and the pusher auger. This achieves the orderly collection and treatment of solids, facilitating subsequent cleaning and disposal, and reducing the risk of environmental pollution caused by the scattering of solids. Through the filter plate and return pipe inside the sludge storage box, the water remaining on the solids in the sludge storage box can be filtered back into the tank, realizing the recycling of water resources. This design can reduce the waste of water resources.

[0013] Beneficial effects

[0014] 1. Compared with existing technologies, this interception device applied to the sedimentation tank of a waterworks can, during interception, use an arc-shaped scraper to scrape solids on the surface of filter plate one into a transfer box, ensuring that filter plate one always remains relatively clean and improving filtration efficiency.
