Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0024] like figure 1 , 2 Shown, a large buoy type decanter construction method, including the following steps:

[0025] 1. Material hoisting: allocate parts according to each sewage treatment tank, and transport the allocated parts to the site;

[0026] 2. Erection: Set up a decanter support 12 at the bottom of the sewage treatment tank, then set up a temporary support 2 equal to the decanter support 12 at the pool wall where the wall-through pipe 5 is provided, and decant the water The device 11 is placed on the decanter support 12, and the elbow 1 is placed on the support 2;

[0027] 3. Connect the wall pipe 5 to one end of the water inlet pipe 4 through the flange 6, connect the other end of the water inlet pipe 4 to one end of the elbow 1 through the connecting bolt 3, and connect one end 8 of the rubber hose 8 to the other end of the elbow 1 ; When installing the con...

Abstract

The invention discloses a method for constructing a large pontoon-type decanter. The method comprises the following steps of: distributing parts to each sewage treatment tank, and transporting to a site; fixedly arranging a decanter bracket at the bottom of the sewage treatment tank, erecting a bracket close to a tank wall provided with a through-wall pipe, arranging the decanter on the decanter bracket, and arranging a bent pipe on the bracket; connecting the through-wall pipe and one end of a water inlet pipe through a flange, connecting the other end of the water inlet pipe and one end of the bent pipe through a connecting bolt, connecting one end of a rubber hose and the other end of the bent pipe, and fixedly connecting the other end of the rubber hose and one end of a decanter steelpipe; connecting the other end of the decanter steel pipe to the decanter, and arranging a decanter pontoon on the top of the decanter; removing the bracket; and performing a full water test. The method has the advantages that by constructing a temporary bracket, the decanter is conveniently and reliably installed; the bracket can be recycled, so that material waste is avoided, cost is low, and construction time is short; the safety factor of each joint is high; and a small area is occupied during construction.

Description

technical field [0001] The invention relates to the technical field of decanters, in particular to a construction method of a large buoy type decanter. Background technique [0002] The construction of large buoy decanters in urban sewage treatment plants can better protect the equipment, ensure the smooth operation of the sewage treatment plant, and reduce the economic losses caused by the damage of the equipment or the shutdown of the sewage treatment plant due to poor maintenance. loss. At present, most of the new small and medium-sized sewage treatment plants in the country have adopted a large number of rotary decanters, but the use of large buoyant decanters is still seldom, and there is no detailed and specific construction guidance for the construction method of large buoyant decanters. Judging from the future development trend, the construction of large buoy decanters in urban sewage treatment plants will be widely used in the construction of various types of sewag...
