Description

Sewage settling tank sediment discharge device

Technical Field

The utility model relates to the technical field of sewage settling tank sediment discharge, in particular to a sewage settling tank sediment discharge device.

Background Art

The sedimentation tank is a key equipment in the oilfield wastewater treatment process. The efficiency of its sediment discharge is directly related to the water quality index of the sedimentation effluent.

In recent years, various problems have arisen in the production and operation of vertical sedimentation tank desilting technology in oil fields, among which the problem of large amount of sediment accumulation at the bottom of the sedimentation tank and inability to discharge smoothly is particularly prominent. On the one hand, this problem has a great impact on the subsequent filtration stage of the sewage treatment process. The suspended solids content in the sewage is high, and the quality of the filtered water is difficult to stably meet the standards; on the other hand, manual desilting of the tank is often required, which causes the tank to be shut down, increasing the load on other structures, affecting the separation effect, and the cleaning labor intensity is high, causing serious environmental pollution.

For example, the sediment discharge device for oilfield sewage settling tank disclosed in Chinese patent CN206252897U performs rotary scraping dynamic mud collection at the bottom of the settling tank through a dynamic mud collecting pipe driven by a central rotating body, wherein the radial rotation of the dynamic mud collecting pipe greatly increases the service area of the mud discharge device, and the mechanical driving action of the scraping screen plate effectively improves the fluidity of the silted sediment. By increasing the service area of the dredging device and improving the fluidity of the silted sediment layer, the sediment at the bottom of the sewage settling tank is completely discharged, thereby achieving the ultimate goal of improving the water quality index of the settling tank and reducing the frequency of manual dredging of the settling tank.

However, when the sediment is to be scraped, the sludge at the bottom of the settling tank adheres to the outside of the scraper, making it impossible to clean the sediment.

For this reason, we urgently need to provide a sewage settling tank sediment discharge device with a flushing structure.
