Embodiment 1

[0021] see Figure 1-3 , a high-efficiency aeration device for sewage purification, comprising an aeration box 1 and a sedimentation box 13 connected thereto, the top of the aeration box 1 is provided with a servo motor 24, and the servo motor 24 is driven and connected with a reversing mechanism, The reversing mechanism is driven and connected with a rotating sleeve 7 installed in the aeration box 1, the rotating sleeve 7 is sleeved with a rotating frame 30, and the rotating frame 30 is provided with a stirring mechanism for stirring. The hollow shaft 2 extending to the inside of the aeration box 1 is rotated inside the rotating sleeve 7, and several nozzles 31 are evenly installed on the side wall of the hollow shaft 2, and a bellows 8 is connected between the aeration box 1 and the sedimentation box 13 The lower end of the bellows 8 is connected with a submersible pump 14 located in the settling tank 13. The settling tank 13 is provided with an adjustment mechanism for driv...

Embodiment 2

[0028] On the basis of Embodiment 1, in addition, this device is also provided with an adjustment mechanism, including an adjustment gear 11 driven by an adjustment motor 29 to rotate. The bellows 8 is sleeved and fixed with a connecting block 9, and the connecting block 9 is vertically A straight toothed rack 10 engaged with the adjusting gear 11 is fixed, and a guide rod 12 fixed on the settling tank 13 is slidably installed in the straight toothed rack 10 .

[0029] The adjustment gear 11 is driven by the adjustment motor 29 to realize the rotation, and the adjustment gear 11 drives the spur rack 10 meshed with it to realize the adjustment effect of the vertical height under the guidance of the guide rod 12, that is, the spur rack 10 can be driven by the connecting block 9. The bellows 8 is adjusted vertically so that the height of the submersible pump 14 inside the sedimentation tank 13 can be adjusted, so that the submersible pump 14 can effectively transport the clarified...

Abstract

The invention discloses a highly-efficient aeration device for sewage purification treatment, and relates to the technical field of forestry machinery. The highly-efficient aeration device comprises an aeration box and a settling box connected with the aeration box, wherein a rotating frame is fixedly arranged on a rotating sleeve pipe in a sleeving mode; a hollow shaft extending into the aerationbox is rotatably arranged in the rotating sleeve pipe; and an air delivery pipe I extending into the hollow shaft is arranged at the outlet end of an air pump I. According to the invention, through arrangement of the air pump I and an air pump II, external air can respectively enter the aeration box through spray heads and an air spray disc; through arrangement of a stirring mechanism, sewage andair in the aeration box can realize aeration under the action of stirring, so the content of oxygen in water is greatly improved, and full oxidation and decomposition of microorganisms to organic matters are promoted; through arrangement of a reversing mechanism, the stirring mechanism can be driven to alternately rotate forwards and backwards, so the stirring efficiency is significantly improved; and through arrangement of stirring plates which can rotate around rotating shafts and can rotate around the rotating sleeve pipe at the same time, sufficient mixing of oxygen and sewage is greatlypromoted, and the aeration effect is significantly improved.

Description

technical field [0001] The invention relates to the technical field of forestry machinery, in particular to a high-efficiency aeration device for sewage purification treatment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid, the purpose of which is to obtain sufficient dissolved oxygen. In addition, aeration also has the purpose of preventing the suspension of the tank from sinking and strengthening the contact between the organic matter in the tank, microorganisms and dissolved oxygen. In thi...
