Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment aeration tank with an aeration enhancement function. Background Art

[0002] The principle of sewage treatment aeration tank is mainly through aeration, that is, by injecting air or oxygen into sewage to promote the metabolic decomposition of microorganisms and the oxidative decomposition of organic pollutants, so as to achieve the purpose of purifying water quality.

[0003] At present, the mechanical aeration device in the aeration tank generally scoops out sewage through a scooping trough installed on the surface of the sewage in the tank to contact the air. Although it can contact with the air when pouring, the pouring range is fixed, resulting in a small area in contact with the air, which causes the problem of low oxygen absorption and the aeration function still needs to be improved. For this reason, we propose a sewage treatment aeration tank with enhanced aeration function. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The rotating shaft rotates to drive the scooping trough on the fixed rod to scoop out sewage continuously. When the scooping trough moves out of the water surface and continues to rotate, the scooped sewage can be poured out. The poured sewage contacts the air and can be aerated. The fallen sewage falls into the water receiving cylinder through the water receiving bucket and can be thrown out through the through hole on the rotating water receiving cylinder to expand the contact area with the air. Compared with the method of sewage falling back directly, the number of contacts is increased, the oxygen absorption is increased, and the aeration function is improved;

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] As mentioned in the background technology, the mechanical aeration device in the prior art generally scoops out sewage through a scooping trough installed on the surface of the sewage in the pool to contact the air. Although the sewage can contact the air when pouring, the pouring range is fixed, resulting in a small area in contact with the air, which causes the problem of low oxygen absorption, and the aeration function still needs to be improved. The utility model proposes a sewage treatment aeration tank with improved aeration function.

[0024] The rotating shaft 3 is evenly provided with fixed rods 4, and the rear ends of the fixed rods 4 are all provided with scooping troughs 5. The rotating shaft 3 drives the scooping troughs 5 on the fixed rods 4 to continuously scoop out sewage. When the scooping troughs 5 are moved out of the water surface and continue to rotate, the scooped sewage can be poured out, and the poured sewage contacts the air and can be aerated.

[0025] The bottom inner wall of the pool body 1 is evenly provided with mounting rods 11, and the mounting rods 11 are L-shaped. A connecting rod 6 is provided at the front left end of the mounting rod 11. A driving motor is provided in the connecting rod 6. A water receiving cylinder 7 is provided on the output shaft of the driving motor. The driving motor is used to drive the water receiving cylinder 7 to rotate. Through holes 8 are evenly provided on the outer bottom of the water receiving cylinder 7, so that the rotating water receiving cylinder 7 can throw water out of the through holes 8, thereby increasing the contact area and contact time with the air. A water receiving bucket 9 is provided on the top of the water receiving cylinder 7 to catch the falling sewage.

[0026] A mounting groove is provided in the connecting rod 6, and the driving motor is arranged in the mounting groove. A porous plate 10 which is interpenetrating with the mounting groove is provided on the right side of the connecting rod 6 for dissipating heat of the driving motor. The driving motor can also be maintained after the porous plate 10 is removed.

[0027] The connecting rod 6 is located above the rotating shaft 3 and does not affect the rotation of the rotating shaft 3 .

[0028] The water receiving bucket 9 is located at the rear side of the fixing rod 4 and does not affect the rotation of the fixing rod 4.

[0029] The mounting rod 11 is located at the rear side of the water scooping trough 5 , which does not affect the rotation of the rotating shaft 3 and the water scooping trough 5 , and can also fix the connecting rod 6 to achieve support for the docking water cylinder 7 .

[0032] The rest of the structure is the same as that of Example 1.

[0033] The rotating shaft 3 rotates, driving the scooping trough 5 on the fixed rod 4 to continuously scoop out sewage. When the scooping trough 5 moves out of the water surface and continues to rotate, the scooped sewage can be poured out. The poured sewage contacts with the air and can be aerated. The fallen sewage falls into the water receiving cylinder 7 through the water receiving bucket 9 and can be thrown out through the through hole 8 on the rotating water receiving cylinder 7, thereby expanding the contact area with the air. Compared with the method in which the sewage directly falls back, the number of contacts is increased, the oxygen absorption amount is increased, and the aeration function is thereby improved.
