Technical Field

[0001] This utility model relates to the technical field of plate-type microporous aerators, specifically an adjustable high-efficiency rubber plate-type microporous aerator. Background Technology

[0002] Aerators are essential equipment for aeration and oxygenation in water supply and drainage. Currently, the energy efficiency of urban wastewater treatment in my country is at a low level, and the energy consumption per ton of water treated is still relatively high. Aerators are a very important part of the biological wastewater treatment process, mainly used to supply oxygen to aerobic tanks, and are also the most energy-consuming component.

[0003] The novel polymer elastomer plate-type microporous aerator disclosed in authorization announcement number CN208594087U includes an aeration membrane, a base fabric, and a base support plate. The upper surfaces of the aeration membrane and the base fabric are heat-sealed together. The edge of the base fabric is fixedly connected to the base support plate. A first air inlet hole is provided on the base support plate, and a second air inlet hole is provided on the base fabric at a position corresponding to the first air inlet hole. An air inlet is fixedly connected to the first air inlet hole, and the air inlet is sealed to the second air inlet hole. A rubber check valve is connected to the air inlet. Aeration holes are evenly distributed on the aeration membrane. With the above technical solution, the beneficial effects of this utility model are: long service life, uniform aeration distribution, high oxygen transfer efficiency, and prevention of sewage backflow.

[0004] Although the aforementioned patents have a long service life and uniform aeration distribution, the installation environment of aerators in wastewater treatment processes is complex and diverse. For example, the tank shapes are different (circular, rectangular, recirculating, etc.). However, once the aerators of the aforementioned patents are installed, their horizontal angle is fixed and cannot be adapted or adjusted. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution:

[0024] An adjustable high-efficiency rubber plate microporous aerator includes a flange joint 1, with a fixed shell 2 fixedly connected to its top. A movable shell 3 is located at the upper end of the fixed shell 2, and an aeration mechanism is located at the top of the movable shell 3. The aeration mechanism includes a pressure plate 5 fixedly connected to the top of the fixed shell 2, and a top plate 6 snapped onto the top of the pressure plate 5. An installation groove 7 is provided in the middle of the top plate 6, and an aeration membrane 8 is sandwiched between the installation groove 7 and the pressure plate 5. The aeration membrane 8 has aeration micropores evenly distributed on it and is made of EPDM. Several slots 9 are provided on both sides of the bottom end of the top plate 6. Several locking blocks 10 are fixedly connected to the outer walls of both sides of the pressure plate 5. The locking blocks 10 are inserted into the slots 9 and locked with bolts. A vent hole 11 communicating with the fixed shell 2 is provided in the middle of the pressure plate 5. A sealing strip 19 is provided on the outer periphery of the upper end of the pressure plate 5. A rotary joint 4 is provided between the fixed shell 2 and the movable shell. An angle adjustment mechanism is provided between the movable shell 3 and the fixed shell 2. The angle adjustment mechanism includes a positioning sleeve 12 fixedly connected to the inner wall of the movable shell 3 and a locking screw 13 threadedly connected to the bottom of one side of the fixed shell 2. Several threaded holes 14 are opened at the bottom of the positioning sleeve 12 with equal arc. Several positioning marks 15 are evenly distributed on the outer periphery of the movable shell 3. A positioning mark 16 that cooperates with the positioning mark 15 is fixedly connected to the outer wall of one side of the fixed shell 2. The angle adjustment mechanism also includes an annular groove 17 opened at the upper end of the fixed shell 2 and a sealing ring 18 fixedly connected to the bottom end of the movable shell 3. The sealing ring 18 is embedded in the annular groove 17 and forms a sealing sliding fit. The fixed end of the rotary joint 4 is fixedly connected to the fixed shell 2, and the movable end of the rotary joint 4 is fixedly connected to the movable shell 3. The fixed shell 2 and the movable shell 3 are rotatably connected through the rotary joint 4.

[0025] In this embodiment, by using the rotary joint 4 in conjunction with the angle adjustment mechanism, the aerator can be adjusted in multiple positions in the horizontal plane according to a preset angle (determined by the arc spacing of the threaded holes 14, etc.), which solves the technical problem that the fixed angle of the existing aerator after installation cannot be adapted to different pool layouts such as circles and rectangles.

[0026] Working principle: When compressed air enters the rotary joint 4 through the flange joint 1, the airflow is delivered upward through the vent 11 to the cavity between the pressure plate 5 and the top plate 6. At this time, the EPDM aeration membrane 8 expands and deforms under the action of air pressure, causing the aeration micropores evenly distributed on its surface to open. Air is released evenly into the water as small bubbles are formed through the micropores. When it is necessary to adjust the installation direction, loosen the locking screw 13 to release the fixation of the positioning sleeve 12. At this time, the movable shell 3 can rotate around the axis of the rotary joint 4. By observing the corresponding position of the positioning mark 15 on the outer periphery of the movable shell 3 and the positioning mark 16 on the fixed shell 2, after rotating the movable shell 3 to the target angle, the locking screw 13 is screwed into the corresponding threaded hole 14 at the bottom of the positioning sleeve 12 to achieve locking and fixation. During this process, the sealing ring 18 at the bottom of the movable shell 3 always maintains a sealed sliding fit with the annular groove 17 at the top of the fixed shell 2 to ensure that no gas leakage occurs during rotation adjustment.

[0027] It should be noted that in the specific implementation of this technical solution, the rotary joint 4 can be configured with conventional rotary connection components in the prior art (such as flange-type rotary joints, bearing-type rotary joints, or universal joint-type rotary joints). Although these rotary connection components are not described in detail in the technical solution, they are common standard parts that can be conventionally selected by those skilled in the art according to actual working conditions. Their structural parameters and performance indicators follow the well-known technology in this field and do not affect the implementation of the core innovation of this solution. In practical applications, the rotary joint 4 is mainly used to realize the relative rotational movement between the fixed shell 2 and the movable shell 3, but its specific type and connection method can be adjusted according to production requirements, all of which fall within the reasonable extension scope of this technical solution.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
