Description

Technical Field

[0001] This utility model belongs to the field of teaching equipment technology, specifically a test bench for testing the oxygenation performance of aeration equipment. Background Technology

[0002] Aeration is a core component of wastewater treatment processes, and its performance testing is a crucial experimental component in the teaching and research of environmental engineering, water supply and drainage science and engineering, and related majors. Through laboratory-scale testing facilities, students can intuitively understand aeration principles, master the testing methods for key oxygenation performance parameters, and compare the operating characteristics of different aeration equipment. Therefore, a well-designed and easy-to-operate teaching experimental platform is essential for improving teaching quality.

[0003] Currently, the aeration performance testing devices used in teaching experiments at universities and vocational colleges are mostly pieced together from multiple independent instruments and devices. For example, the air source may be a single vortex blower or electromagnetic air pump, the stirring function relies on an external agitator, and the gas flow control, power supply, and data monitoring are controlled by different instruments and circuits. The lack of a unified mechanical structure and electrical control integration among these functional modules results in a complex experimental system. When conducting comparative experiments with different air sources or different aeration discs, it is necessary to manually disassemble and replace multiple components and reconnect the air and electrical circuits, making the operation cumbersome and time-consuming.

[0004] Therefore, there is an urgent need for a highly integrated and modular dedicated teaching experimental platform that can integrate gas source, stirring, control and detection functions into one unit to simplify the operation process, enrich the experimental content and improve the teaching effect.

[0029] 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.

[0030] Please see Figure 1 One specific embodiment of this utility model is: an experimental platform for measuring the oxygenation performance of an aeration device, comprising: an experimental platform 1, two aeration tanks 2 on the experimental platform 1, and a control box 3 on the experimental platform. The control box 3 can control a mechanical stirring structure 4, a vortex blower structure 5, and an electromagnetic air pump structure 6, thereby conducting aeration experiments on the aeration tanks 2 using three different aeration methods: mechanical stirring aeration, vortex blower aeration, and electromagnetic air pump aeration.

[0031] Please see Figure 2-35-6, the experimental platform 1 includes: a base body 101, with two first bases 102 symmetrically arranged on both sides of the upper part of the base body 101. Each first base 102 is a flat, circular protruding structure. A circular mounting groove 103 is provided on each first base 102 for mounting the aeration tank shell 201 of the aeration tank 2. A sealing ring made of elastic material is provided inside the mounting groove 103 to prevent water leakage after the aeration tank shell 201 is installed on the first base 102. Multiple fixing buckles 104 are provided around the mounting groove 103 on the first base 102 for fixing the aeration tank shell 201 installed in the mounting groove 103. A second base 105 is also provided on the first base 102. The second base 105 is a protruding circular ring with a diameter smaller than the diameter of the mounting groove 103. A threaded structure is provided on the inner wall of the second base 105 for mounting the aeration disc 202. The second base 105 also has an internal sealing ring made of elastic material to prevent air leakage after the aeration disc 202 is installed on the second base 105. The outer side of the aeration disc 202 has a threaded structure that matches the second base 105, and the side of the aeration disc 202 also has multiple wing-shaped handles 203 for easy tightening or removal from the second base 105. The aeration disc 202 is available in various pore sizes and materials, allowing for selection and replacement according to experimental needs.

[0032] The fixing buckle 104 is a lever-type buckle, including a collar 1043. A first lever 1041 and a second lever 1042 are respectively provided on both sides of the collar 1043, forming an L-shaped lever. The collar 1043 is mounted on a lever shaft 1045 and can rotate around the lever shaft 1045. A protrusion 1044 is provided on the collar 1043, and a slider 1046 with an inclined surface is provided on the lever shaft 1045. The slider 1046 is connected to the lever shaft 1045 via a spring 1047. When the collar 1043 rotates, the protrusion 1044 slides along the inclined surface of the slider 1046, pressing the slider 1046 and compressing the spring 1047. When the fixed buckle 104 is in the fixed state, the protrusion 1044 passes the dead point, i.e. the widest point, of the inclined surface of the slider 1046. When the first lever 1041 is in the vertical position, the restoring force of the spring 1047 will lock the protrusion 1044 into the stable position, thereby pressing the second lever 1042 against the protruding outer edge of the aeration tank shell 201, achieving locking and preventing accidental release.

[0033] Please see Figure 2-4The mechanical agitation structure 4 includes: agitator blades 401, which are mounted in the aeration tank shell 201 via a rotating shaft. The upper part of the rotating shaft is connected to a rotary motor 402, which is placed on top of the aeration tank shell 201. The rotary motor 402 drives the agitator blades 401 to rotate, causing the water in the aeration tank 2 to flow, generating eddies or waves, and increasing oxygen dissolution. The rotary motor 402 is connected to a control box 3 via wires, is powered by the control box 3, and can receive electrical signals transmitted by the control box 3.

[0034] The vortex blower structure 5 includes a vortex blower 501, and the airflow generated by the vortex blower 501 is output through a first output pipe 502. The electromagnetic air pump structure 6 includes an electromagnetic air pump 601, and the airflow generated by the electromagnetic air pump 601 is output through a second output pipe 602. Both the vortex blower 501 and the electromagnetic air pump 601 are connected to the control box 3 via wires, are powered by the control box 3, and can receive electrical signals transmitted by the control box 3.

[0035] The control box 3 includes a three-way solenoid valve 309, which is a two-position three-way solenoid valve. Its two input ports are connected to the first output pipe 502 and the second output pipe 602, respectively, and its output port is connected to the first connecting pipe 310. The three-way solenoid valve 309 can receive electrical signals from the control box 3 and control the opening or closing of the two input ports through the control box 3. The outlet of the first connecting pipe 310 is connected to two second connecting pipes 311. The airflow generated by the vortex fan 501 or the electromagnetic air pump 601 is evenly distributed to the two second connecting pipes 311 through the first connecting pipe 310. The outlet of the second connecting pipe 311 is connected to a flow meter 306, which can detect the airflow rate output from the second connecting pipe 311 and display it on a scale in real time. The outlet of the flow meter 306 is connected to the third connecting pipe 312. The airflow is transmitted to the second base 105 through the third connecting pipe 312. The airflow then passes through the aeration disc 202 installed on the second base 105 to form bubbles of different sizes and flow rates, which enter the outer shell 201 of the aeration tank to aerate the water in the aeration tank 2.

[0036] The control box 3 further includes: a first switch 301 and a second switch 302. The first switch 301 controls the opening and closing of the interface between the vortex blower 501 and the three-way solenoid valve 309 connected to the first output pipe 502; the second switch 302 controls the opening and closing of the interface between the electromagnetic air pump 601 and the three-way solenoid valve 309 connected to the second output pipe 602, thereby controlling whether the aeration tank 2 is aerated by the vortex blower or by the electromagnetic air pump. Two third switches 303 control the opening and closing of the rotary motor 402, thereby controlling the mechanical stirring and aeration of the aeration tank 2. Two knobs 304 control the motor speed of the rotary motor 402, thereby controlling the stirring speed of the stirring blades 401. Two dissolved oxygen indicators 305 are also installed on the top of the control box 3. The two dissolved oxygen indicators 305 are connected to two dissolved oxygen detectors 308 respectively. The dissolved oxygen detectors 308 are installed inside the outer shell 201 of the aeration tank and can monitor the dissolved oxygen value of the water in the aeration tank 2 in real time and display it on the dissolved oxygen indicator 305.

[0037] The rotary motor 402, vortex blower 501, electromagnetic pump 601, three-way solenoid valve 309, flow meter 306, and dissolved oxygen detector 308 used in this embodiment are all commercially available conventional products. Their internal structure and working principle are well-known technologies in the field and will not be described in detail here. The rotary motor 402, vortex blower 501, and electromagnetic pump 601 are all powered by the power supply unit 307 within the control box 3, which is connected to an external power source. The control logic implemented by the above-mentioned electric components through the control box 3, such as start / stop via a switch, speed adjustment via a knob, and switching of solenoid valve pathways, has been fully described above. The specific circuit connections inside the control box, such as relay control, signal transmission, and power management, are electrical technologies that can be conventionally configured by those skilled in the art according to functional requirements and do not need to be elaborated upon here. This embodiment has clearly and completely disclosed the structural composition and working method of this utility model, meeting the requirements of sufficient disclosure under the Patent Law.
