Description

Technical Field

[0001] This utility model relates to the field of aeration treatment technology, specifically an aeration device for underground water wells. Background Technology

[0002] With the rapid development of industry, the extensive use of chemical fertilizers and pesticides in agriculture, and the indiscriminate discharge of urban sewage, groundwater pollution has become increasingly serious. Groundwater in many areas has been contaminated by pollutants such as heavy metals, organic matter, nitrogen, and phosphorus, leading to water quality deterioration. This not only affects the safety of residents' drinking water but also causes serious damage to the ecological environment. Aeration technology, as an effective groundwater remediation method, can increase the dissolved oxygen content in polluted groundwater by injecting air or oxygen into it, thereby promoting the growth and metabolism of aerobic microorganisms and accelerating the degradation and transformation of pollutants.

[0003] Currently, some groundwater well aeration devices use a simple single-pipe air distribution method, where gas enters the well directly from a single pipe. This results in uneven gas distribution within the well, with excessive aeration in areas near the inlet and insufficient aeration in areas far from the inlet. Consequently, the aeration effect throughout the well is inconsistent, failing to achieve uniform treatment of groundwater. Furthermore, traditional groundwater aeration devices are mostly made of stainless steel or engineering plastics, with a single set costing over a thousand yuan. They also require complex piping systems and power equipment, leading to long construction periods and high installation and maintenance costs, making them difficult to promote in rural areas or resource-limited regions. Utility Model Content

[0004] The purpose of this invention is to provide an aeration device for underground water wells to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An aeration device for groundwater wells, comprising:

[0007] The annular gas transmission pipe is made of PVC pipe. The annular gas transmission pipe is installed at the wellhead. Several connecting pipes are connected at equal angles at the bottom of the annular gas transmission pipe. The annular gas transmission pipe is connected to the air pump through connecting pipes.

[0008] Several vertical gas transmission pipes are provided. The material is corrosion-resistant PVC pipe with a diameter greater than 50mm. The vertical gas transmission pipes are respectively connected to the bottom of several connecting pipes. The vertical gas transmission pipes are laid vertically on the well wall.

[0009] The aeration branch pipe is made of PVC pipe and is provided in several units. Each aeration branch pipe is connected to a number of vertical air supply pipes. The aeration branch pipe is set perpendicular to the vertical air supply pipes. A number of aeration holes are evenly opened on the side of the aeration branch pipe. The diameter of the aeration holes is ≥3mm and the inclination is 45°. An aeration port is opened at the end of the aeration branch pipe.

[0010] Aeration heads are provided in several units. The aeration heads are installed at the aeration ports at the ends of the aeration branch pipes. The aeration heads include rubber diaphragm type or stainless steel screen type.

[0011] Adjustable supports, with several in number, are provided to assist in supporting the aeration branch pipes;

[0012] Several tees are provided for connecting the vertical air supply pipe and the aeration branch pipe.

[0013] Furthermore, it also includes an annular pipe, the periphery of which is provided with several connecting pipes II, and the ends of several aeration branch pipes are respectively connected to the corresponding connecting pipes II.

[0014] Furthermore, both ends of the aeration branch pipe are provided with threaded grooves on their outer walls, and the aeration branch pipe is threadedly connected to the tee pipe and the butt pipe.

[0015] Furthermore, the rubber diaphragm of the aeration head is 2-3mm thick, with a cross-shaped cut in the center, which opens and closes naturally with the airflow and closes to prevent backflow of impurities when the machine stops. The screen aperture of the aeration head is 3-5mm.

[0016] Furthermore, the aeration head is made from waste tire rubber cut into diaphragms or recycled stainless steel mesh through secondary processing, reducing the amount of new materials used.

[0017] Furthermore, the adjustable bracket includes a base, an upper clamping ring, and a lower clamping ring. A support column is fixedly connected to the top surface of the base. Two sliding slots are opened on the top surface of the support column. Two plug-in rods are fixedly connected to the bottom surface of the lower clamping ring. The two plug-in rods are slidably inserted into the two sliding slots respectively. Several threaded holes are opened at equal intervals on the outer side walls of the two plug-in rods.

[0018] Furthermore, the aeration branch pipe has a pre-reserved reverse flushing interface, which is connected to a high-pressure water pump through a pipeline to achieve pore flushing.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By connecting several pairs of pipes at equal angles at the bottom of the annular gas transmission pipe, the gas is evenly distributed to each vertical gas transmission pipe. Then, the gas is evenly transported to each aeration branch pipe through a three-way pipe, so that the aeration holes and aeration heads can release gas into the well more evenly, thus improving the uniformity of aeration.

[0021] By opening several aeration holes on the aeration branch pipe, the air bubbles are dispersed and the attachment of suspended matter is reduced, which increases the contact area and contact time between the gas and water, allowing the gas to dissolve in the water more effectively, improving the aeration efficiency, and thus enhancing the treatment capacity of groundwater.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5In this embodiment of the invention, an aeration device for a groundwater well includes an annular air supply pipe 100, a vertical air supply pipe 200, an aeration branch pipe 300, an aeration head 400, an adjustable bracket 500, and a tee pipe 600. The annular air supply pipe 100 is made of PVC pipe and is horizontally installed at the wellhead via a mounting bracket. Several connecting pipes 110 are connected at equal angles to the bottom of the annular air supply pipe 100. The annular air supply pipe 100 is connected to an air pump via a connecting pipe. In areas without a power grid, a solar panel can be selected to power the air pump. Several vertical air supply pipes 200 are provided, made of corrosion-resistant PVC pipe with a diameter of 50-100mm. Each vertical air supply pipe 200 is connected to the bottom of one of the connecting pipes 110. The vertical air supply pipes 200 are laid vertically on the well wall. The aeration branch pipe 300... The system uses PVC pipes and has several aeration branch pipes 300 connected to corresponding vertical air supply pipes 200 via several tee pipes 600. The aeration branch pipes 300 are perpendicular to the vertical air supply pipes 200. Several aeration holes 320 are evenly distributed on the side of the aeration branch pipes 300. The diameter of the aeration holes 320 is ≥3mm and the inclination is 45°. An aeration port 310 is provided at the end of the aeration branch pipe 300. Several aeration heads 400 are provided and installed at the aeration ports 310 at the end of the aeration branch pipes 300. The aeration heads 400 include rubber diaphragm type or stainless steel screen type. Several adjustable brackets 500 are provided to assist in supporting the aeration branch pipes 300. A backwashing interface is reserved on the aeration branch pipes 300, and a high-pressure water pump is connected through a pipeline to achieve pore flushing.

[0029] Specifically, the air pump delivers air into the annular air supply pipe 100 through a connecting pipe. The air then flows through several vertical air supply pipes 200 into the corresponding aeration branch pipes 300, causing the aeration heads 400 to generate a large number of microbubbles, increasing the dissolved oxygen content in the groundwater. The rubber diaphragm type aeration head 400 or the stainless steel screen type aeration head 400 can effectively prevent backflow of impurities while ensuring good air permeability. The aeration branch pipes 300 horizontally disperse the compressed air to the central area of ​​the well shaft, and the aeration holes 320 on their sides are used to initially release the airflow (forming microbubbles). The aeration holes 320 on the aeration branch pipes 300 are arranged in a uniform ring, which makes the bubbles evenly dispersed, increases the contact area between the bubbles and the groundwater, and improves the aeration efficiency.

[0030] like Figure 2-3 As shown, in this embodiment, an annular pipe 700 is also included. Several connecting pipes 710 are arranged around the annular pipe 700. The ends of several aeration branch pipes 300 are respectively connected to the corresponding connecting pipes 710. The outer walls of both ends of the aeration branch pipe 300 are provided with threaded grooves 330. The aeration branch pipe 300 is threadedly connected to the tee pipe 600 and the connecting pipes 710, which enables quick and convenient disassembly and replacement, reducing maintenance costs and workload.

[0031] In this embodiment, the annular pipe 700 is made of corrosion-resistant PVC material and is circular in shape. The number of connecting pipes 710 around the annular pipe 700 is determined according to the actual aeration requirements and the size of the well. The annular pipe 700 connects several aeration branch pipes 300 together, making the connection more secure. The air pump delivers gas to the annular air supply pipe 100 through the connecting pipe. The annular air supply pipe 100 distributes the gas evenly to each vertical air supply pipe 200. The gas enters the connected aeration branch pipe 300 directly through the tee pipe 600. The gas entering the aeration branch pipe 300 is discharged from the aeration holes 320 on the side of the pipe and the aeration head 400 at the end, releasing bubbles into the surrounding water. Another part of the gas enters the annular pipe 700, circulates within the annular pipe 700, and is then distributed to the connected aeration branch pipe 300 through the connecting pipe 710. This effectively improves the uniformity of aeration throughout the well, allowing the groundwater to be treated more comprehensively.

[0032] like Figure 5 As shown, in this embodiment, the adjustable bracket 500 includes a base 510, an upper clamping ring 530, and a lower clamping ring 540. The base 510 is fixedly connected to the bottom of the well by expansion bolts. A support column 520 is fixedly connected to the top surface of the base 510, which serves as a support and positioning element. The support column 520 can be made of stainless steel or hard plastic to ensure sufficient strength and corrosion resistance. Two sliding slots 521 are provided on the top surface of the support column 520. Two plug-in rods 550 are fixedly connected to the bottom surface of the lower clamping ring 540. The two plug-in rods 550 are slidably inserted into the two sliding slots 521 respectively. Several threaded holes 551 are provided at equal intervals on the outer side walls of the two plug-in rods 550. The upper clamping ring 530 and the lower clamping ring 540 together constitute a structure for clamping the aeration branch pipe 300.

[0033] In practice, the aeration branch pipe 300 is placed on the lower clamping ring 540, and then the upper clamping ring 530 is placed on the lower clamping ring 540. The upper clamping ring 530 and the lower clamping ring 540 are tightly connected by bolts or clips to securely clamp the aeration branch pipe 300. When it is necessary to adjust the height of the bracket according to factors such as the depth of the well and the installation position of the aeration branch pipe 300, first loosen the bolts fixing the lower clamping ring 540, and then move the lower clamping ring 540 up and down to allow the insertion rod 550 to slide in the sliding slot 521. After adjusting to the appropriate height, insert the bolt into the corresponding threaded hole 551 and tighten it to fix the lower clamping ring 540 on the support column 520.

[0034] like Figure 1-3As shown, in this embodiment, the rubber diaphragm type aerator head 400 has a rubber diaphragm thickness of 2-3mm and a cross-shaped cut in the center, allowing it to open and close naturally with airflow. It closes when the machine stops to prevent backflow of impurities. The stainless steel mesh type aerator head 400 has a mesh aperture of 3-5mm. The aerator head 400 uses diaphragms cut from waste tire rubber or recycled stainless steel mesh after secondary processing, reducing the amount of new materials used.

[0035] In practice, the thickness of the rubber diaphragm is precisely controlled between 2-3 mm. This thickness range ensures that the rubber diaphragm has sufficient flexibility to open and close naturally under airflow, while also ensuring that it has sufficient strength to prevent damage from water flow impact or impurities. The screen aperture is set to 3-5 mm. This aperture size ensures that the gas can pass through smoothly while effectively blocking larger impurities from entering the aeration pipe. At the same time, it allows the gas to be released in the form of relatively uniform fine bubbles, improving aeration efficiency. In response to the call for environmental protection and resource conservation, the aeration head 400 in this embodiment is made from waste tire rubber cut into diaphragms or recycled stainless steel mesh through secondary processing. This reduces the amount of new materials used, lowers production costs, and is also conducive to resource recycling and environmental protection.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
