Problems solved by technology

Although the rotation speed of the walking frame is relatively slow, it will cause some disturbance to the deposited sludge particles
And when there is a lot of sludge deposited on the bottom of the sewage tank, it is easy to cross the upper end of the mud scraper, reducing the effect of sludge discharge

Embodiment Construction

[0014] Such as figure 1 As shown, the present invention comprises a pool body 1, a walking platform 2 arranged on the side wall of the pool body 1, a walking frame 3 arranged at the upper end of the pool body 1, and a sewage tank 4, a sewage tank 4 is arranged inside the pool body 1 The inside of the clean water tank 5 is provided with a scum tank 6 inside.

[0015] The lower end of the sewage tank 4 is provided with a plurality of evenly distributed sewage tanks 7, and the lower end of the sewage tank 4 is provided with a mud scraper 8 opened in the direction of rotation. Frame 3 is fixedly connected.

[0016] The sewage discharge tanks 7 are all inclined to the direction of sewage flow, which can increase the area of ​​the sewage discharge tanks 7 .

[0017] The mud scraper 8 is involute, which greatly reduces the agitation of the mud scraper 8 to the sewage.

[0018] Working principle: when the involute scraper 8 rotates, it scrapes the deposited sludge at the bottom of ...

Abstract

The invention discloses a novel scraper shallow air flotation machine, which comprises a pool body, a walking platform arranged on the side wall of the pool body, and a walking frame arranged on the upper end of the pool body. The sewage tank, the inside of the sewage tank is provided with a clear water tank, and the inside of the clean water tank is provided with a scum tank; The mud scraper is opened in the direction, and the mud scraper is fixedly connected with the walking frame through a vertical connecting rod. The beneficial effect of the present invention is that the mud scraping efficiency is improved, and the disturbance of the mud scraper to sewage is reduced at the same time.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a novel scraper shallow air flotation machine. Background technique [0002] The shallow air flotation machine adopts the principle of dissolved air flotation. Part of the dissolved air water is passed into the water to be treated, and the suspended solids or oil in the water are floated out of the water surface by using the tiny bubbles released in the dissolved air water, thereby Environmental protection equipment to achieve the purpose of solid-liquid separation. [0003] At present, the existing air flotation machine still has the following technical defects: the mud scraper at the lower end of the sewage tank is perpendicular to the flow direction of the sewage, and there is only one mud discharge tank at the lower end. Although the rotation speed of the walking frame is relatively slow, it will cause some disturbance to the deposited sludge particles. And...
