A vertical buoy type decanter

Abstract

The invention provides a vertical float type decanter. The decanter comprises a decanter plate, a float and three guide rods. The float is a triangle formed by splicing three stainless steel pipes with the thickness being 1.5 mm and the diameter being 250 mm, triangular connection plates are welded to joints of the stainless steel pipes, vertical guide holes are formed in the triangular connection plates, guide sleeves are welded into the guide holes, a ball regulator is arranged on the side wall of each guide sleeve, the guide rods are sleeved with the guide sleeves, and each guide rod is provided with adjusting holes corresponding to the corresponding ball regulator at intervals from top to bottom. The decanter plate comprises a plate body, a downflow weir, a drainage pipe and three connection arms, wherein the downflow weir is arranged in the center of the plate body, the drainage pipe is arranged at the bottom end of the downflow weir, and the three connection arms are connected with the plate body and the downflow weir. Each connection arm inclines downwards by 15-35 degrees, the connection arms are provided with vertical screws, the vertical screws penetrate through corresponding through holes formed in the stainless steel pipes of the float, and fixing nuts are in screwed connection with the top ends of the vertical screws. The vertical float type decanter is small in occupied area, simple in structure, convenient to manufacture and capable of automatically adjusting the float.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a buoyancy decanter. Background technique [0002] At present, with the widespread application of the sequencing batch activated sludge wastewater treatment process, the water outlet method needs to meet the requirements of intermittent water outlet according to the operation cycle. In order to meet this requirement, domestic and foreign manufacturers have developed various types of decanters. The main types of equipment are: 1. Rotary decanters. , drain the pool water out of the pool. This type of decanter is most commonly used in China. Its advantage is that it uses a weir to flow out water, and the water is more uniform. However, there are two main problems. One is that this type of decanter can only be installed against the wall of the pool, and the outlet weir is short. At about 10m, and only one side of the weir tank decants water, the water output per unit weir width is l...
