Abstract

A fast settling concentration tank for sewage in gangue includes an outer cylinder and an inner cylinder connected in the outer cylinder by a first bracket. The upper end of the inner cylinder is a sewage inlet. A baffle plate is provided in the middle of the inner cylinder by a second bracket. A feeding gap is formed between the edge of the baffle plate and the inner wall of the inner cylinder. At least one annular return plate is fixed on the outer wall of the inner cylinder. An overflow gap is formed between the outer edge of the return plate and the inner wall of the outer cylinder. A residue outlet is formed at the lower portion of the outer cylinder. An overflow tank is formed at the upper end of the outer cylinder. The overflow outlet of the overflow tank is separated from the sewage inlet.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a settling concentration technique for sewage in gangue, and more particularly to a fast settling concentration tank for sewage in gangue.

[0003] 2. Description of the Prior Art

[0004] A conventional sewage treatment system for metal mine and mineral separation comprises a settling pool, a rake frame, a transmission mechanism, a lift mechanism, a feeding mechanism and a discharge mechanism. When it is used to treat sewage, the sewage in the gangue is drained to a concentration pool through a feeding mechanism. The concentration pool is added with Aluminum Oxide to form mud. The rake frame is lowered to the concentration pool through the lift mechanism. The rake frame is used to stir the mud in the concentration pool through the transmission mechanism. The slag in the mud is settled to the lower portion of the concentration pool by gravity and drained through the discharge mechanism. The sepa...
