Embodiment 1

[0036] refer to figure 1 , figure 2 , image 3 , Figure 5 , Figure 7 and Figure 8 , a combined aeration treatment device for chemical sewage, comprising a tank body 1, an aeration mechanism is arranged in the tank body 1, a bottom plate 2 is connected to the inner wall of the tank body 1, and a casing 3 is connected to the top inner wall of the tank body 1 in rotation, The outer wall of the casing 3 is connected with a stirring mechanism, and the inside of the casing 3 is connected with a threaded rod 4 through the first bearing. The output end is connected with a rotating shaft 501, the outer wall of the rotating shaft 501 is connected with a first gear 5011 and a second gear 5012, and the second gear 5012 is a half gear, and the outer wall of the casing 3 is connected with a third gear that meshes with the first gear 5011 6. The outer wall of the threaded rod 4 is connected with the fourth gear 7 which meshes with the second gear 5012, the outer wall of the tank bod...

Embodiment 2

[0042] refer to Figure 2-4 , a combined aeration treatment device for chemical sewage, which is basically the same as in Example 1, furthermore, the aeration mechanism includes a blower 12, the blower 12 is connected to the outer wall of the tank body 1, and the air outlet end of the blower 12 is connected with The exhaust pipe 121, the end of the exhaust pipe 121 away from the blower 12 passes through the tank body 1 and is connected with four air distribution pipes 122, the four air distribution pipes 122 are evenly distributed on the outside of the threaded rod 4 in a circle, and the outer wall of each air distribution pipe 122 Both are connected with an aeration head 123.

[0043] Control the operation of the blower 12, so that the air enters the four air distribution pipes 122 through the exhaust pipe 121, and then enters the aeration head 123, so that the air is converted into air bubbles in the aeration head 123 and enters the sewage, so that the oxygen dissolves into ...

Embodiment 3

[0045] refer to figure 2 , image 3 , Figure 4 and Figure 8 , a combined aeration treatment device for chemical sewage, which is basically the same as that of Embodiment 1, furthermore, the outer wall of the threaded rod 4 is connected with a fifth gear 13, and the outer wall of the fifth gear 13 is meshed with a sixth gear 141, The outer wall of the sixth gear 141 is connected with a fixed rod 14, and the fixed rod 14 is connected to the outer wall of the base plate 2 in rotation. The gas head 123 activities offset.

[0046] The end of the connecting plate 142 away from the sixth gear 141 is connected with a moving block 144 , and the inner wall of the tank body 1 is dug with an annular groove 145 matching with the moving block 144 .

[0047] During the rotation of the threaded rod 4, the fifth gear 13 and the sixth gear 141 will mesh with each other, so that the sixth gear 141 drives the connecting plate 142 to rotate with the fixed rod 14 as the center of circle, and...

Abstract

The invention provides a combined aeration treatment device for chemical sewage, which comprises a tank body, an aeration mechanism is arranged in the tank body, a bottom plate is connected to the inner wall of the tank body, a sleeve is rotatably connected to the inner wall of the top of the tank body, a stirring mechanism is connected to the outer wall of the sleeve, a threaded rod is rotatablyconnected into the sleeve through a first bearing, the bottom of the threaded rod is rotationally connected into the bottom plate, the outer wall of the top of the tank body is connected with a motor,the output end of the motor is connected with a rotating shaft, the outer wall of the rotating shaft is connected with a first gear and a second gear, and the second gear is a half gear. According tothe invention, large bubbles can be conveniently divided into small bubbles, the rising speed of the bubbles in the wastewater is slowed down, the mixing efficiency of the bubbles and the wastewaterin the same time is increased, and the small bubbles can more quickly dissolve oxygen into the water so as to improve the concentration of dissolved oxygen, so that the sewage treatment effect is improved, and the cost is lower.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a combined aeration treatment device for chemical sewage. Background technique [0002] Aeration refers to increasing the contact area between water and air by inflating water or mechanically agitating. It is an intermediate process of aerobic biological treatment of wastewater. The water surface is vigorously stirred with impeller brushes or other tools to continuously contact the atmosphere with a new interface. Water treatment methods for exchanging gaseous substances and removing volatile substances in water, or allowing gases to escape from water, such as removing water odor or harmful gases such as carbon dioxide and hydrogen sulfide, or dissolving oxygen into water to increase the concentration of dissolved oxygen, To achieve the purpose of removing iron and manganese or promoting the degradation of organic matter by aerobic microorganisms. [0003] At present, t...
