Description

Technical Field

[0001] This application relates to the field of aerator design, and more specifically, to an aerator for treating sewage in rivers. Background Technology

[0002] In water treatment processes, aerators are key equipment for biological pretreatment of water supply and biological treatment of wastewater. Their function is to use specific technical measures to transfer air into the liquid within the aeration tank, supplying the oxygen needed for aerobic biological metabolism, while simultaneously ensuring thorough and uniform mixing of the water within the tank, thus achieving the purpose of biological treatment.

[0003] The bottom of the riverbed is uneven due to the sediment of sludge and rocks. Common aerators usually connect the aeration discs and the blower with stainless steel pipes. To place the aeration discs at the bottom of the riverbed to achieve the best mixing effect between the air and the river water, it is very complicated and time-consuming to adjust the angle and length of the stainless steel pipes when arranging the aeration discs. Summary of the Invention

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section above, some embodiments of this application provide an aerator for treating river sewage, comprising: a blower forming an exhaust end; a ventilation structure forming an input interface and an output interface, the input interface being connected to the exhaust end of the blower; a flexible hose, one end of which is connected to the output interface of the ventilation structure; and an aeration disc connected to the other end of the flexible hose.

[0006] Furthermore, the ventilation structure includes: a first pipe, a second pipe, and a third pipe; one end of the first pipe forms the input interface, the other end of the first pipe is connected to the second pipe, the second pipe is parallel to the edge of the riverbank, multiple third pipes are provided, one end of the multiple third pipes is arranged along the length direction of the second pipe and connected to the second pipe, and the other end of the third pipe forms the output interface.

[0007] Furthermore, the ventilation structure includes a valve; the valve is disposed on the third pipe.

[0008] Furthermore, the inner diameters of the first pipe, the second pipe, and the third pipe decrease sequentially.

[0009] Furthermore, the aeration disc includes: a disc body and a buckle; the buckle is used to engage the hose, the buckle is fixed to one side of the disc body, and multiple buckles are arranged in a circumferential array around the axis of the disc body.

[0010] Furthermore, the buckle forms multiple slots along its length, and the slots form a detachable connection with the hose.

[0011] Furthermore, one side of the disc body has a central protrusion forming a frustum shape, and the buckle is fixed to the curved surface of the frustum.

[0012] The beneficial effects of this application are as follows:

[0013] Air from the blower exhaust end passes through the ventilation structure and hoses before entering the aeration discs. When the aeration discs need to be placed on the riverbed, workers simply throw them into the river, and the hoses are pulled into the water by the discs. Because the hoses are flexible, they can bend to allow air to pass through the discs regardless of their position relative to the ventilation structure, thus simplifying the arrangement of the aeration discs and saving time and manpower.

[0026] Reference Figure 1-2 ,

[0027] An aerator for treating sewage in rivers includes: a blower, a ventilation structure, a hose, and an aeration disc. The blower is a conventional blower product, forming the exhaust end for outputting air, and is installed on the riverbank. The ventilation structure is located on the riverbank, forming an input interface and an output interface. The input interface is connected to the blower, and the air output by the blower enters the ventilation structure through the input interface. The hose is DN10, 10 meters long, and is immersed in the river water. The aeration disc is a conventional technology concept, placed on the riverbed. The output interface of the ventilation structure is connected to one end of the hose, and the other end of the hose is connected to the aeration disc. Air enters the aeration disc through the hose, and then forms microbubbles from the aeration disc before entering the water at the riverbed.

[0028] Specifically, the ventilation structure includes a first pipe, a second pipe, and a third pipe. One end of the first pipe forms an input interface and connects to the exhaust end of the blower. The other end of the first pipe connects to the middle of the second pipe via a tee. The second pipe runs parallel to the edge of the riverbank. Multiple third pipes are installed, with their upper ends arranged along the length of the second pipe and connected to it via reducing tees, allowing one blower to deliver air into multiple aeration discs. The other end of the third pipe forms an output interface, which is a pagoda-shaped connector. The output interface is inserted into the port of a flexible hose for connection.

[0029] Specifically, the ventilation structure includes a valve. In this embodiment, the valve is a ball valve, which is installed on the third pipe. The operator can control the opening and closing of a single third pipe through a single valve, thereby controlling the opening and closing of a single aeration disc.

[0030] Specifically, as the air drawn in by the blower is distributed to each hose through the ventilation structure, the total amount of air gradually decreases. In order to avoid a drop in air pressure, the inner diameters of the first, second, and third pipes decrease sequentially, so that the air pressure passing through the ventilation structure gradually increases, causing the air to be discharged from the aeration disc under high pressure, thus reducing the probability of the aeration disc becoming clogged.

[0031] Specifically, the aeration disc includes a disc body and clips. The clips are used to secure the hose; they are integrally formed and fixed to one side of the disc body. Multiple clips are arranged in a circumferential array around the axis of the disc body; in this embodiment, there are eight clips. Before throwing the aeration disc into the riverbed, workers measure the required length of the hose based on the width and depth of the river channel. Excess hose is then coiled and clipped to the clips to prevent the excessively long hose from getting tangled in foreign objects on the riverbed, making the aeration disc difficult to retrieve.

[0032] Specifically, the buckle forms multiple slots along its length. In this embodiment, there are four slots. The slots form a detachable connection with the hose. The worker can spiral the excess hose around the axis of the disc from the center outward and insert it into the four slots one by one.

[0033] Specifically, one side of the disc has a raised center forming a frustum shape, and the buckle is integrally formed and fixed with the curved surface of the frustum, so that the hose spirally wound on the buckle can be separated layer by layer.

[0034] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
