Description

Technical Field

[0001] The present application relates to the field of sewage treatment, and in particular to a multi-layer aeration pipe of a composite ecological filter. Background Art

[0002] In modern production industry and production life, a large amount of sewage of various types will be generated, which contains a large amount of organic matter and harmful substances. If it is discharged directly into nature without treatment, it will cause eutrophication of water bodies, trigger the massive reproduction of algae and other aquatic plants, consume oxygen in the water, cause hypoxia in the water body, and even produce stench and death. And it will cause serious harm to the environment and human health. After the sewage is treated, it can be transformed into normal industrial water or domestic water that meets the regulations, so it is necessary to purify the sewage. Existing sewage treatment mostly uses sewage treatment pools to treat sewage in biological or chemical forms. Among them, the composite ecological filter can use a biological layer with physical properties of fillers and aeration devices according to the characteristics of the sewage to be treated. The aeration pipes of the current composite ecological filter are mostly single-layer structures, and the bubbles generated rise quickly, stay in the water body for a short time, and the bubbles are easy to merge with each other during the rising process, making it more difficult to merge with the water body, reducing the sewage treatment efficiency and increasing the sewage treatment cost.

[0003] For example, the publication number is CN204211528U, which is a multi-layer aeration device, and its structure includes a tower body, an aeration plate, an air inlet pipe, a water inlet and a water outlet. The aeration plate is provided with a main pipe and a plurality of branch pipes, and the branch pipes are evenly provided with a plurality of aeration holes. The main pipe on each aeration plate is connected to the air inlet pipe through an air inlet valve, and a filler is also provided in the tower body. 2 to 5 layers of aeration plates are evenly distributed in the tower body. The above-mentioned aeration device only plays a certain role in increasing the flow of water bodies by cross-arranging and installing multi-layer aeration pipes, and it is impossible to cut and push the bubbles to further increase the flow of water bodies while strengthening the contact between the bubbles and the water body. Therefore, the present application designs a multi-layer aeration pipe of a composite ecological filter tank that can reduce the size of bubbles and reduce bubble fusion. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-layer aeration pipe of a composite ecological filter tank, comprising a tank body, a packing layer, an aeration mechanism and a cutting mechanism for cutting bubbles in a water body driven by gas flow, wherein the packing layer is arranged at the upper inner wall of the tank body, the aeration mechanism is arranged at the lower end of the tank body, the cutting mechanism is arranged above the aeration mechanism, aeration mechanisms and cutting mechanisms are arranged in several groups, and several groups of aeration mechanisms and cutting mechanisms are staggered in the vertical direction, an impeller and a partition are arranged inside the aeration mechanism, the upper part of the impeller passes through the aeration mechanism and is plugged into the cutting mechanism, and the partition is fixedly connected to the inner wall of the aeration mechanism; the partition drives the impeller to rotate by blocking the gas in the aeration mechanism, thereby driving the cutting mechanism to cut the bubbles generated by the aeration mechanism.

[0006] The gas in the aeration mechanism is separated by the provided partition, so that the impeller provided in the middle of the aeration mechanism is driven by the gas circulation to drive the cutting mechanism to rotate and cut the bubbles generated by the aeration mechanism, thereby reducing the size of the bubbles and making it easier for the bubbles to merge with the water body, thereby improving the sewage treatment efficiency and enhancing the sewage treatment effect.

[0012] By setting up the inverted cone aeration plate, the bubbles generated by the aeration holes are blocked by the plate body when moving upward, which slows down the rising speed of the bubbles and increases the time the bubbles stay in the water body. The spiral guide grooves are set to prevent the bubbles at the bottom of the plate from escaping and move along the spiral guide grooves, which further increases the residence time of the bubbles and enhances the integration of the bubbles with the water body.

[0013] The arc-shaped blade can be set to rotate and cut the bubbles generated by the aeration mechanism, and at the same time, the bubbles can be thrown around by rotation, thereby increasing the distance between the bubbles, reducing the fusion of bubbles, increasing the contact area between the bubbles and the water body, and shortening the time required for a single sewage treatment.

Among them, the blades of the impeller 5 are of a semicircular structure, and gas is transported into the water body through the aeration mechanism 3 to form bubbles in the water body, so that the water body contacts the gas and oxygen is dissolved in the water body. At the same time, the gas in the aeration mechanism 3 cooperates with the blocking of the partition 6 to drive the impeller 5 to rotate, so that the cutting mechanism 4 plugged into the impeller 5 cuts the bubbles formed by the aeration mechanism 3, thereby increasing the contact area between the bubbles and the water body.

The partition 6 at the connection between the aeration pipe 32 and the gas generator 31 is in an L-shaped structure, so that the gas generator 31 transports the gas to one side of the partition 6. The tail end of the partition 6 away from the gas generator 31 is not connected to the end of the aeration pipe 32, so that the gas can be transported to the other side of the partition 6 and enter the aeration plate 33. The gas flows on one side of the partition 6 to drive the impeller 5 to rotate. As the gas flows to the other side of the partition 6, the impeller 5 continues to be driven and enters the aeration plate 33 through the air supply pipe 34 for aeration. The impeller 5 is arranged in the middle of the aeration pipe 32, and the partition 6 at the position of the impeller 5 is provided with a hollow portion 61 according to the shape of the impeller 5, so that the impeller 5 can rotate normally.

[0026] See also Figure 3 and Figure 6 The aeration plate 33 includes a plate body 331, aeration holes 332 and a spiral guide groove 333. The plate body 331 is an inverted cone structure. A plurality of aeration holes 332 distributed in a circumference are fixedly connected to the lower part of the plate body 331.

The lower end of the impeller 5 is rotatably connected to the upper end of the air supply pipe 34.

[0028] See also Figure 6 The aeration hole 332 is a cylindrical structure connected up and down, and the lower end is an inclined surface; the inclined surface faces one side of the spiral guide groove 333, and when the bubbles flow out of the aeration hole 332, they fall into the spiral guide groove 333 from the inclined surface side.

[0029] As another example, Figure 3 As shown, the cutting mechanism 4 includes a knife seat 41 and a blade 42, the blade 42 is fixedly connected to the knife seat 41, and the lower end of the knife seat 41 is plugged into the upper end of the impeller 5.

The arc-shaped blades 42 cut the bubbles and collect the bubbles on the inner wall of the blades 42, and throw the bubbles out by rotating, so that the intervals between the bubbles become larger.

[0031] Working principle: When in use, the sewage to be treated is first transported to the pool body 1 through the sewage pipe 11. When the sewage volume reaches above the composite filler layer 2, the gas generator 31 is turned on. The gas generator 31 transports the gas used for sewage treatment to one side of the partition 6 in the aeration pipe 32. The gas flow in the aeration pipe 32 drives the impeller 5 to rotate. The gas passes through the tail end of the aeration pipe 32 and then turns to the other side of the partition 6. It is transported to the aeration plate 33 through the air supply pipe 34 and finally flows out through the aeration holes 332. It moves upward along the spiral guide groove 333 under the influence of buoyancy and continues to move upward in the water body at the edge of the aeration plate 33. At this time, the rotation of the cutter disc driven by the impeller 5 drives the arc blade 42 to rotate and cut the bubbles, cutting the bubbles into smaller bubbles, and throwing the bubbles outward as the blade 42 moves, increasing the distance between the bubbles.
