DETAILED DESCRIPTION

[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings of the specification.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0035] Reference Figures 1-7 One embodiment of the present invention provides a kitchen wastewater treatment system, which comprises at least a treatment tank 1 and a concentration detection unit. Specifically, an outer pipe 2 (first air inlet) is fixedly disposed at the bottom of the treatment tank 1, and an inner pipe 3 (second air inlet) is disposed inside the outer pipe 2 and fitted against its own inner wall. The inner pipe 3 can rotate inside the outer pipe 2. An opening 4 is constructed on the wall of the outer pipe 2, and multiple air inlets 5 are constructed on the wall of the inner pipe 3. The diameter of the multiple air inlets 5 varies linearly along the circumference of the inner pipe 3. For details, please refer to [reference needed]. Figure 3 As shown, when the inner tube 3 rotates to different positions, the air inlets 5 of different diameters are connected to the outlet 4. One end of the inner tube 3 is connected to the outside and is used to connect to the air supply source. In order to facilitate the air supply, a main pipe 6 is fixedly installed on the outside of the treatment tank 1. The end of the inner tube 3 is rotatably connected to the main pipe 6. The main pipe 6 is connected to the air supply source. The treatment tank 1 is also equipped with a first drive motor 7 (drive unit), which is connected to the other end of the inner tube 3 for transmission, so that the inner tube 3 can be controlled to rotate to different angles.

[0036] Regarding the structure of the concentration detection unit, specifically, as follows: Figures 4-7As shown, it includes an inlet channel 8, which is configured in the sewage inlet pipe of the treatment tank 1, so that the sewage first passes through the inlet channel 8 when entering the treatment tank 1. The inlet channel 8 is provided with a rotating shaft 9 that can rotate along its own axis, and an interceptor 10 (blocking part) is fixedly connected to it. The interceptor 10 can be a float or an interceptor plate, etc., and the number can be set to several. An abutment end 15 is fixedly connected to the inlet channel 8. A flywheel 14 is rotatably connected to one end of the rotating shaft 9, and a second pressure detection unit 16 abuts between the flywheel 14 and the abutment end 15. The other end of the rotating shaft 9 is connected to a force-applying frame 12 through a first pressure detection unit 11. Specifically, the first pressure detection unit 11 is connected to the rotating shaft 9 and abuts against the force-applying frame 12; of course, the first pressure detection unit 11 can also be connected to the force-applying frame 12 and abut against the end of the rotating shaft.

[0037] The force-applying frame 12 is used to apply the detection driving force. Specifically, a second drive motor 13 is fixedly configured here, which is relatively fixed to the water inlet channel 8. The output end of the second drive motor 13 is connected to the force-applying frame 12, which provides a rotational force to the force-applying frame 12, so that the force-applying frame 12 contacts the first pressure detection unit 11 to drive the rotating shaft 9 and the interceptor 10 to rotate in the sewage. Both the first pressure detection unit 11 and the second pressure detection unit 16 can be pressure strain gauges, so that the pressure can be tested. An electrical linkage is established between the first pressure detection unit 11 and the first drive motor 7, and an electrical linkage is established between the second pressure detection unit 16 and the air supply source. If the air supply source is an air pump or blower, it can establish an electrical linkage with the second pressure detection unit 16, so as to control the air intake speed according to the detected pressure.

[0038] Based on the above, during the process of sewage passing through the inlet channel 8, when the oil concentration in the sewage is higher, the water becomes more viscous. At this time, the interceptor 10 is more difficult to rotate in the water, that is, the resistance it encounters is greater. Therefore, the force value detected by the first pressure detection unit 11 is greater. At this time, the control inner tube 3 corresponding to the first drive motor 7 rotates to keep the larger diameter air inlet 5 connected to the outlet 4. When the airflow enters the water from the inner tube 3, it needs to pass through the larger diameter air inlet 5, so that the diameter of the formed bubbles is larger. Based on this, conversely, when the oil concentration in the sewage is lower, the control air inlet 5 with a smaller diameter is connected to the outlet 4, so that the diameter of the bubbles formed at the bottom of the treatment tank 1 is smaller and the number is larger, which is conducive to the floating of small oil particles. Thus, the effect of automatically adjusting the diameter of the generated bubbles according to the oil concentration is achieved to maintain a good oil floating effect.

[0039] Furthermore, based on the above, the direction of the sewage flow in the inlet channel 8 is as follows: Figure 5As shown by the middle arrow, when the sewage passes through the interceptor 10, it also exerts a thrust along its rotation axis on the interceptor 10, which is a thrust on the second pressure detection unit 16. The faster the sewage flows, the greater the force value detected by the second pressure detection unit 16, that is, the faster the sewage flows into the pool. Therefore, according to the linkage between the second pressure detection unit 16 and the air supply source, when the detected inflow is larger, the working speed of the air supply source will also increase accordingly, thereby ensuring that the provided air flow rate can match the sewage inflow in the treatment pool 1, so that the power of the air supply source during operation matches the actual demand, thus avoiding energy waste.

[0040] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
