Embodiment 1

[0011] Embodiment 1: as figure 1 As shown in the figure, an installation structure of a rotating disc surface aerator for a cylindrical tank body includes bearing housings 2 fixed on both sides of the tank body 1 wall, a rotating shaft 3 pierced in the tank body 1, and a reducer 6 . A variable frequency drive motor 4 capable of reversing forward and reverse. The two ends of the rotating shaft 3 pass through the wall of the tank body 1 and are installed in the bearing seat 2. The driving end of the rotating shaft 3 passes through the bearing seat 2 and is connected to the main shaft of the driving motor 4. 4 The groups of rotating discs 5 are sleeved on the rotating shaft 3 at intervals, and the outer diameter of each group of rotating discs 5 decreases gradually from the inside to the outside along with the height of the section of the tank body 1, forming a stepped shape.

[0012] Every group of rotating disks 5 is made up of a piece of rotating disks, and the size of rotatin...

Embodiment 2

[0013] Embodiment 2, with reference to Embodiment 1, other features remain unchanged, consists of 2 groups of rotating discs, each group of rotating discs is composed of two rotating discs, the size of the rotating discs is 1200mm, 1200mm, 800mm, 800mm. The distance between adjacent discs is 250mm~300mm.

Embodiment 3

[0014] Embodiment 3: With reference to Embodiment 1, other features remain unchanged. It consists of 2 groups of rotating discs. The first group of rotating discs is composed of three rotating discs. The size of the rotating discs is 1000mm. The second group of rotating discs consists of one rotating Composed of discs, the size of the rotating disc is 800mm. The distance between adjacent discs is 250mm~300mm.

Abstract

The invention discloses a mounting structure of a rotating disc surface aerator for a cylindrical tank. The mounting structure comprises bearing seats fixedly connected to two sides of the cylindricalwall of the tank, a rotating shaft arranged in the tank in a penetrating manner and a driving motor capable of rotating forwards and backwards, wherein two ends of the rotating shaft penetrate the cylindrical wall of the tank and are mounted in the bearing seats; the driving end of the rotating shaft penetrates the bearing seats and is connected with a main shaft of the driving motor; a pluralityof groups of rotating discs are connected to the rotating shaft at intervals in a sleeving manner, and the outer diameters of each group of rotating discs are gradually reduced from inside to outsidealong with height of the tank section to form a step shape. Surface aeration efficiency is high, and size is small.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an installation structure for an aerator on the surface of a rotating disc in a horizontal tank. Background technique [0002] The rotary disc aerator is generally used for surface aeration of sewage treatment, and it is widely used in the oxidation ditch process because it has good aeration and push flow effects, but the oxidation ditch is generally an open-air civil construction facility, and it is not used In the horizontal tank body, the rotary disc aerator is set in the horizontal tank body and no one uses it. Contents of the invention [0003] The object of the present invention is to provide a rotary disc aerator applicable to horizontal cylindrical tanks, which has high surface aeration efficiency and small volume. [0004] In order to achieve the purpose of the above invention, the technical solution of the present invention is: an installation structure for a rotating...
