Efficient sedimentation centrifuge

Abstract

The invention provides an efficient sedimentation centrifuge capable of providing high working efficiency, automatic residue scraping and continuous operation. The efficient sedimentation centrifuge consists of a centrifuge body, a rotary drum, an impeller, an auger scraper, a drain pipe, a water outlet pipe, a motor and the like. During operation, to-be-treated waste water having certain pressure flows into the rotary drum through a water inlet pipe. Due to the fact that waste water in the rotary drum is subjected to solid-liquid separation under the centrifugal effect, separated clear water is discharged out of the centrifuge through the water outlet pipe, and the impeller produces certain centrifugal force with the high-speed rotation of the rotary drum. Due to the fact that liquid flows from the upper portion to the lower portion in the rotary drum, water of an inner ring of the impeller is forced to be discharged towards an outer ring of the impeller under the centrifugal force produced by the impeller, the impeller produces corresponding resistance through self rotation while having a centrifugal force water discharging function, accordingly the impeller and the rotary drum automatically produce relative differential. Due to the fact that the auger scraper is fixedly connected with the impeller, the auger scraper driven by the impeller can continuously scrap sediments on the wall of the rotary drum to the bottom of the rotary drum, then the sediments are discharged out of the centrifuge through the drain pipe, and the whole operation process is efficiently and continuously completed.

Description

technical field [0001] The invention relates to a settling centrifuge, especially a high-efficiency settling centrifuge composed of a machine body, a drum, an impeller, an auger scraper, a sewage discharge pipe, a water inlet pipe, a water outlet pipe and a motor. Background technique [0002] The structure of the decanter centrifuge currently on the market is composed of a body, a drum, a water inlet pipe, an overflow port and a motor. During operation, the sewage to be treated flows into the drum from the water inlet pipe. After the drum is driven by the motor, the sewage in the drum will undergo solid-liquid separation and settlement. The separated clarified water flows out of the machine from the overflow, and the separated solid The particles settle on the drum wall to form sediment. When the sediment accumulates to a certain thickness, it needs to be shut down frequently and scraped off manually, which results in the disadvantage of low working efficiency. Contents o...

Problems solved by technology

During operation, the sewage to be treated flows into the drum from the water inlet pipe. After the drum is driven by the motor, the sewage in the drum will undergo solid-liquid separation and settlement. The separated clarified water flows out of the machine from the overflow, and the separated solid The particles settle on the drum wall to form sediment. When the sediment accumulates to a certain thickness, it is necessary to stop frequently and manually scrape and clean it, resulting in the disadvantage of low working efficiency.
