Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a sewage pool bottom aeration device. Background Art

[0002] Industrial production and urban life generate large amounts of wastewater. Industrial wastewater is particularly polluting because it contains high levels of pollutants, including organic and inorganic substances. Therefore, wastewater can only be recycled or directly discharged into the environment after undergoing environmentally friendly treatment to remove pollutants.

[0003] Sewage is pumped into a sewage tank and treated using a mature ecological treatment process, resulting in not only significant treatment results but also an environmentally friendly process. Specifically, ecological sludge is mixed into the sewage, where microorganisms degrade pollutants while adsorbing them. During the microbial treatment process, aeration is required for aerobic treatment. This process not only pumps oxygen into the sewage for microbial degradation but also stirs the ecological sludge with the sewage airflow, enhancing treatment effectiveness.

[0004] Currently, aeration pipes are used in sewage pools to release aeration gases. However, since the aeration pipes are laid at the bottom of the sewage pool, in order to increase the aeration coverage, the aeration pipe laying surface needs to be increased. Obviously, the laying cost is relatively high.

[0005] Secondly, horizontally laid aeration pipes are easily buried by sludge, which can easily lead to silt accumulation at the bottom of the sewage pool and blockage of the aeration pipes, thus greatly reducing the aeration effect. This is especially true when a large amount of sludge settles during the sewage treatment process, which can make the aeration effect even worse. Utility Model Content

[0006] Based on the above background, the purpose of the present utility model is to provide a sewage pool bottom aeration device.

[0007] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0008] A sewage pool bottom aeration device comprises a plurality of aeration mechanisms connected and arranged;

[0009] The aeration mechanism comprises a long aeration tube, and the long aeration tube is equipped with a plurality of aeration cylinder components;

[0015] Preferably, the first blade portion and the second blade portion of the aeration guide plate at the upper end are arranged to be inclined upward;

[0018] Preferably, the aeration cylinder assembly comprises a pair of aeration cylinders;

[0019] The aeration cylinders are connected through a connecting pipe, and the connecting pipe is connected to the long aeration pipe.

[0020] Preferably, the long aeration tubes are connected via a U-shaped connecting pipe;

[0021] The U-shaped connecting pipe is connected to an aeration inlet pipe, and the aeration inlet pipe is equipped with an aerator.

[0039] Example 1

[0040] like Figure 1-5 As shown, a sewage pool bottom aeration device includes a plurality of interconnected aeration mechanisms, specifically, aeration mechanisms symmetrically arranged in the upper and lower parts, so as to achieve aeration treatment of the upper and lower layers of the sewage system in the sewage pool.

[0041] The specific structure of the aeration mechanism is as follows: Each aeration mechanism includes a long aeration tube 1, which is connected to a plurality of aeration cylinder assemblies 21. Specifically, the aeration cylinder assemblies 21 include a pair of aeration cylinders, which are connected by a connecting pipe, which is connected to the long aeration tube 1. The aeration cylinders are also provided with a plurality of small holes 213. According to existing methods, to reduce clogging of the small holes 213, circular filter screens are fixed in these small holes 213.

[0042] The aeration cylinder includes a cylinder portion 211 and a tapered portion 212 integrally formed on the cylinder portion 211 . The tapered portion 212 is connected to the long aeration tube 1 (ie, the tapered portion 212 is connected to the connecting pipe).

[0043] The advantages of using an aeration cylinder structure as an aeration structure are: during the aeration process, the cylindrical aeration cylinder has a large aeration volume, which can fully stir up the ecological mud air flow in the sewage; secondly, it can effectively avoid the burial of settled sludge.

[0044] The aeration tubes 1 are connected to each other through a U-shaped connecting pipe 11; the U-shaped connecting pipe 11 is connected to an aeration inlet pipe 12. According to the existing aeration method, the aeration inlet pipe 12 is equipped with an aerator (not shown in the figure). During operation, the aerator releases gas.

[0045] The aeration cylinders at the upper and lower ends are fixedly connected by a U-shaped connecting rod 22 .

[0046] Example 2

[0047] like Figure 1-5 As shown, based on the structure of Example 1, in order to increase the aeration coverage area and solve the defects of traditional aeration pipes that the laying area is too large and the laying cost is too high, the above-mentioned aeration mechanism also includes aeration guide plates 3 respectively installed on the aeration long tubes 1, and the aeration guide plates 3 include a first blade portion 31 and a second blade portion 32 arranged at an angle.

[0048] Specifically, during the aeration process, the aeration airflow passes through the first blade portion 31 and the second blade portion 32 to guide the aeration gas, thereby increasing the aeration coverage area.

[0049] Specifically, the first blade portion 31 and the second blade portion 32 of the aeration guide plate 3 at the upper end are tilted upward; the first blade portion 31 and the second blade portion 32 of the aeration guide plate 3 at the lower end are tilted downward.

[0050] Because aeration plate 3 covers both the upper and lower portions of the aeration cylinder, during aeration, the aerated gas is distributed to both sides by the V-shaped aeration plate 3 at the upper portion, and the V-shaped structure directs the aerated gas toward the upper portion of the sewage layer. Similarly, the V-shaped aeration plate 3 at the lower portion directs the aerated gas to both sides, and the inverted V-shaped structure directs the aerated gas toward the lower portion of the sewage layer. This significantly increases the coverage of the aeration gas radiation within the sewage, not only increasing the agitation effect on the ecological sludge in the sewage tank but also significantly improving the efficiency of sewage aeration treatment.

[0051] A plurality of weight-reducing holes 34 are defined on the first blade portion 31 and the second blade portion 32 .

[0052] Example 3

[0053] like Figure 1-5As shown, this embodiment builds on the structure of Example 2. Angle adjustment plates 33 are fixedly attached to the left and right ends of the aeration plate 3. The lower ends of these angle adjustment plates 33 are threadedly connected to the aeration tube 1. Correspondingly, the tube 1 has a threaded structure, and the lower ends of the angle adjustment plates have threaded holes. During operation, the angle position of the aeration plate 3 can be adjusted by rotating the angle adjustment plates, thereby facilitating the adjustment of the aeration gas flow direction, significantly enhancing the aeration effect.

[0054] The upper end of the angle adjustment plate is integrally formed with a protruding connection portion, and the connection portion is threadedly connected with a connection bolt, and the connection bolt is fastened to the aeration guide plate 3.

[0055] Example 4

[0056] like Figure 1-5 As shown, this embodiment builds on the structure of Example 3. The bottom of the sewage tank bottom aeration device is suspended in the sewage tank via support structures spaced apart on both sides. Specifically, the support structure includes a U-shaped support 41 supported on the lower end of the long aeration tube 1. A telescopic rod 42 is fixedly connected to the bottom of the U-shaped support 41. Telescopic rod 42 is a conventional telescopic sleeve rod disclosed in the prior art. Its bottom is fixedly connected to a base 411 supported on the bottom of the sewage tank. Base 411 is anchored to the bottom of the sewage tank, such as by an anchor rod.

[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
