Description

Technical Field

[0001] This utility model relates to the field of aeration head technology, specifically to an adjustable aeration head assembly. Background Technology

[0002] In wastewater treatment, aquaculture, and other scenarios requiring continuous oxygen supply, aeration systems are widely used in various biochemical reaction tanks and water purification systems as core equipment for increasing dissolved oxygen content in water. Traditional aeration devices mostly use aeration heads with fixed orifice diameters and structures. Their air output and bubble distribution often depend on pipeline pressure and layout, resulting in poor adjustment flexibility and difficulty in fine-tuning according to different treatment stages or local water quality differences. This not only easily leads to insufficient aeration or oxygen waste in certain areas but may also affect overall treatment efficiency and energy consumption.

[0003] Furthermore, since the aeration system operates underwater for extended periods, suspended particles, silt, algae, and other impurities in the water can easily clog the aeration holes. This is especially true when aeration intensity is low or the system is shut down, significantly increasing the risk of backflow of water and impurities into the pipes, further exacerbating the system's failure rate and maintenance difficulty. Although some existing devices attempt to incorporate check valves or flow-limiting structures to prevent clogging, their response sensitivity, structural compactness, and service life remain insufficient.

[0004] Therefore, there is an urgent need to design an adjustable aeration head assembly to solve these problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable aeration head assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable aeration head assembly, comprising a box body, wherein air outlets are provided on both the front and back sides of the box body, and an anti-clogging air outlet assembly is installed on the air outlets; an air inlet pipe is provided on the top side wall of the box body; and an adjustment assembly is provided in the inner cavity of the box body, comprising an adjustment bolt and an adjustment plate, wherein two adjustment plates are placed in the inner cavity of the box body, and the adjustment plates are connected by a connecting rod, forming an overall U-shape; an adjustment bolt is provided on the connecting rod, and both adjustment plates are in contact with the inner cavity side wall of the box body.

[0007] As a preferred technical solution of this utility model, the anti-clogging venting component is conical in shape, comprising a circular base and a rubber diaphragm, wherein the rubber diaphragm is triangular in shape and arranged in a ring array on the circular base, and a hole communicating with the box body is opened in the middle of the circular base.

[0008] As a preferred technical solution of this utility model, the adjustment plate is provided with an air outlet.

[0009] As a preferred technical solution of this utility model, the adjusting bolt includes a screw and a nut, wherein the screw is connected to the connecting rod and the nut is screwed onto the screw.

[0010] As a preferred technical solution of this utility model, the outer wall of the box body is provided with a hole for the screw to move up and down.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention provides an adjustable aeration head assembly. By incorporating an adjustment component and an anti-clogging air outlet component, it effectively achieves the distribution and control of aeration airflow and automatic anti-clogging function of the channels. The adjustment plate structure in the adjustment component can be moved up and down by adjusting bolts, thereby flexibly controlling the relative position of the air outlet of the adjustment plate and the air outlet of the housing, realizing the adjustment of aeration intensity in different areas, and meeting the oxygen supply requirements under various operating conditions. Compared with traditional fixed-structure aeration devices, this device has excellent adjustment performance and adaptability, significantly improving the system's flexibility and operating efficiency.

[0013] Furthermore, the anti-clogging air outlet assembly features an automatic opening and closing structure with a rubber diaphragm. It opens the air outlet channel when gas is supplied and automatically closes when gas supply stops, effectively preventing water backflow and blockage caused by suspended particles entering the channel. This reduces the frequency of manual maintenance and extends the equipment's lifespan. The overall structure is compact and easy to install, making it suitable for various aeration applications such as wastewater treatment and aquaculture, demonstrating excellent engineering practicality and promising prospects for widespread adoption.

[0020] 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.

[0021] See Figure 1-5 This utility model provides an adjustable aeration head assembly, which has a compact structure and multiple functions. It can adjust the gas distribution state according to actual needs and effectively prevent the air outlet from being blocked, thereby improving aeration efficiency and equipment operation stability.

[0022] The adjustable aeration head assembly described in this embodiment includes a hollow box 1. The box 1 is generally rectangular in shape and made of corrosion-resistant plastic or stainless steel to adapt to humid and highly corrosive environments. Multiple air outlets are provided on both the front and back of the box 1. Each air outlet is equipped with an anti-clogging air outlet component 4. The anti-clogging air outlet component 4 has a conical structure, consisting of a circular base 41 and a rubber diaphragm 42. The rubber diaphragm 42 is triangular and evenly distributed in a ring array on the circular base 41. A through hole is provided in the center of the base 41, which communicates with the air outlet inside the box 1 to ensure smooth gas passage. The rubber diaphragm 42 can slightly bulge under gas impact to form a channel, and when the gas supply stops, it rebounds to cover the through hole, effectively preventing water backflow and impurities from entering, thus achieving the anti-clogging function.

[0023] The top side wall of the box 1 is provided with an air inlet pipe 2 for connecting to an external blower system, which delivers compressed air into the box 1 via a blower. After the air enters the box 1, it is distributed by an internal regulating component 3 and then discharged into the water through the air outlet.

[0024] The adjustment assembly 3 includes two adjustment plates 32 and a connecting rod. The adjustment plates 32 are connected by the connecting rod to form an integral U-shaped structure, which is attached to the left and right side walls of the inner cavity of the box body 1. Each adjustment plate 32 has several air outlets 5, which are distributed to correspond to the air outlets on the box body 1. By moving the position of the adjustment plate 32, the alignment of the air outlets on the adjustment plate 32 with the air outlets on the box body 1 can be achieved, thereby adjusting the actual air output. The length and width of the adjustment plate 32 are smaller than the length and width of the front panel and back panel of the box body 1.

[0025] An adjusting bolt 31 is provided in the middle of the connecting rod. The adjusting bolt 31 includes a screw and a nut. The screw is fixedly connected to the connecting rod, and the nut can be screwed onto the screw. The adjusting bolt 31 passes through a guide hole provided on the outer wall of the housing 1. The user moves the screw up and down, thereby driving the connecting rod and the adjusting plate 32 to rise and fall synchronously to achieve the adjustment purpose. The guide hole is used to limit the direction of movement of the screw and ensure its smooth operation. After adjusting to the appropriate position, the nut can be tightened.

[0026] Through the above structural design, users can quickly adjust the position of the adjusting plate 32 by rotating the adjusting bolt 31 during operation, flexibly controlling the air output intensity and uniformity. Simultaneously, the automatic opening and closing mechanism of the rubber diaphragm 42 effectively prevents impurities from entering and clogging the channels, improving the durability and stability of the entire system. This device is particularly suitable for applications such as sewage treatment plants and aquaculture farms where high aeration efficiency and operational reliability are required.
