Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a prefabricated integrated wastewater treatment device. Background Technology
[0002] With increasing environmental awareness and rising demand for wastewater treatment, wastewater treatment technology has received widespread attention in the environmental field. Among wastewater treatment processes, prefabricated integrated wastewater treatment devices are being used due to their advantages such as convenient installation and high treatment efficiency.
[0003] In the aerobic treatment stage of wastewater, the aerobic chamber plays a crucial role. The aerobic chamber is a place where aerobic microorganisms oxidize and decompose organic matter in wastewater. Its principle is to introduce air into the wastewater through an aeration device to increase the dissolved oxygen content in the wastewater, which meets the oxygen conditions required for the metabolism of aerobic microorganisms. At the same time, the mixing device ensures that the wastewater and oxygen are in full contact, ensuring that the microorganisms can effectively decompose pollutants in the wastewater.
[0004] However, existing prefabricated integrated sewage treatment devices have some problems in practical use. For example, the aeration heads are easily clogged or attached by impurities in the sewage during long-term operation, which affects the aeration effect. The common treatment method is to clean them manually on a regular basis. This method is not only time-consuming and labor-intensive, but also cannot clean the aeration heads in time, which will lead to uneven aeration, affecting the growth environment of aerobic microorganisms and treatment efficiency. Therefore, we propose a prefabricated integrated sewage treatment device. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 4. In this utility model, when a set of active plates is provided, the active plates of a single set will trigger the cleaning components on the aeration heads in sequence, so that the cleaning components will cover and clean the aeration heads in sequence, thereby effectively reducing the impact on microorganisms and the aeration system.

[0028] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.
[0029] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.
[0030] Example 1:
[0031] like Figures 1-6 As shown, a prefabricated integrated sewage treatment device includes a sewage treatment tank 1. The sewage treatment tank 1 includes an anaerobic chamber, an aerobic chamber 4, and a secondary sedimentation chamber. The aerobic chamber 4 is located between the anaerobic chamber and the secondary sedimentation chamber, and the aerobic chamber 4 is interconnected with both the anaerobic chamber and the secondary sedimentation chamber. The connection structure and connection method of the anaerobic chamber, the aerobic chamber 4, and the secondary sedimentation chamber are disclosed technologies and will not be described in detail here. The sewage treatment tank 1 is equipped with a sealed cover for cleaning the interior of each of the anaerobic chamber, the aerobic chamber 4, and the secondary sedimentation chamber.
[0032] Furthermore, an aeration device 2 and a stirring device 3 are installed on the sewage treatment tank 1 at the position corresponding to the aerobic chamber 4. A transmission pipe 7 is installed at the output end of the aeration device 2. The end of the transmission pipe 7 away from the aeration device 2 extends to the bottom of the aerobic chamber 4. Aeration heads 9 are arranged at intervals on the transmission pipe 7 and are interconnected with the inside of the transmission pipe 7.
[0033] Furthermore, a rotating shaft 5 is installed on the output end of the stirring device 3, and stirring blades 6 for stirring the solution inside the aerobic chamber 4 are installed in a ring at intervals on the side wall of the rotating shaft 5.
[0034] Furthermore, at least two sets of aeration heads 9 are provided on the transmission pipe 7, and the position of the rotating shaft 5 corresponds to the middle position of the two sets of aeration heads 9.
[0035] Furthermore, the aeration head 9 is equipped with a cleaning component for cleaning the aeration head 9.
[0036] Furthermore, the cleaning component is equipped with an adjustment component that can drive the cleaning component to perform cleaning operations on the aeration head 9.
[0037] Furthermore, an active plate 8 is provided on the side wall of the rotating shaft 5, which can trigger the adjustment component when the rotating shaft 5 rotates, and there is at least one set of active plates 8.
[0038] Furthermore, the cleaning components include a mounting housing 10, a fixed storage plate 12, a fixing block 13, an adjusting plate 16, a folding arc plate 20, a folding strip 21, and a cleaning block 22. The mounting housing 10 is fixedly mounted on the aeration head 9 and is an annular block shape. The fixing block 13 is located at the top center of the aeration head 9. Fixed storage plates 12 are fixedly mounted on both sides of the fixing block 13. The side of the fixed storage plate 12 away from the fixing block 13 is fixedly mounted on the inner wall of the mounting housing 10 at the corresponding position, and the curvature of the fixed storage plate 12 is adapted to the curvature of the aeration head 9. The inner side of the fixed storage plate 12 is hollow, and the hollow area of the inner side of the fixed storage plate 12 penetrates the side wall of the fixed storage plate 12 corresponding to the aeration head 9 and the side wall of the fixed storage plate 12.
[0039] Furthermore, the fixed storage plate 12 is provided with a foldable and adjustable folding arc plate 20 inside. An adjustment plate 16 is provided on the side wall of the fixed storage plate 12, and the position of the adjustment plate 16 corresponds to the end of the folding arc plate 20 away from the inner side of the fixed storage plate 12. The adjustment plate 16 and the folding arc plate 20 are connected to each other. Folding strips 21 are provided on the inner side of the folding arc plate 20 near the mounting shell 10 and the fixed block 13.
[0040] In this embodiment, the foldable strips 21 at both ends of the foldable arc plate 20 enable the foldable arc plate 20 to expand or fold inside the mounting shell 10 in an arc shape. The arc expansion of the foldable arc plate 20 inside the mounting shell 10 allows for gradual adjustment of the aeration head 9. When the aeration head 9 is partially covered, a localized area with a low dissolved oxygen concentration is formed around the covered area. This local dissolved oxygen gradient can guide the directional movement of microorganisms. Microorganisms are oxygen-attracting, and under the stimulation of this dissolved oxygen gradient, they will move towards the area with a higher dissolved oxygen concentration, thereby promoting the redistribution of microorganisms in the aerobic tank.
[0041] Furthermore, both ends of the folded arc plate 20 are connected to the inner side of the fixed storage plate 12 and the inner side of the adjustment plate 16 near the aeration head 9.
[0042] In this embodiment, by bringing the two connecting ends of the folded arc plate 20 closer to the aeration head 9, the folded arc plate 20 can effectively conform to the surface of the aeration head 9 and move when it expands or folds and contracts.
[0043] Furthermore, a cleaning block 22 is fixedly installed at the folded corner of the folded arc plate 20 near the aeration head 9. The material of the cleaning block 22 includes, but is not limited to, sponge.
[0044] In this embodiment, the cleaning block 22 provided at the bottom of the folded arc plate 20 enables the aeration head 9 to be cleaned when the folded arc plate 20 expands.
[0045] In this embodiment, by setting cleaning blocks 22 on the folding corners of the folded arc plate 20, the spaced folded arc plates 20 can effectively increase the interval space for cleaning the aeration head 9 when cleaning it, so that the same area on the aeration head 9 can be effectively cleaned multiple times, greatly improving the cleaning efficiency of the aeration head 9.
[0046] Furthermore, the adjustment assembly includes a driven plate 11, an adjustment block 14, an adjustment groove 15, a fixed plate 17, a connecting column 18, and a torsion spring 19. The fixed block 13 is hollow inside. The adjustment block 14 is located on the side of the fixed block 13 away from the aeration head 9. The connecting column 18 is fixedly installed at the bottom of the adjustment block 14. The fixed plate 17 is located inside the fixed block 13, and the fixed plate 17 and the connecting column 18 are connected to each other at the ends away from the adjustment block 14. The torsion spring 19 is provided on the inner side of the fixed block 13. The connecting column 18 is located on the inner side of the torsion spring 19. The two ends of the torsion spring 19 are respectively fixedly installed on the corresponding side walls of the fixed plate 17 and the fixed block 13. The driven plate 11 is fixedly installed on the side wall of the adjustment block 14 near the rotating shaft 5, and the position of the driven plate 11 corresponds to the position of the active plate 8.
[0047] In this embodiment, the rotation of the rotating shaft 5 causes the driving plate 8 to push the driven plate 11 after rotating to a designated position, which in turn causes the driven plate 11 to drive the adjusting block 14 to rotate. When the driving plate 8 and the driven plate 11 disengage, the driven plate 11 and the adjusting block 14 will return to their original positions through the torsion spring 19.
[0048] Furthermore, the adjustment groove 15 is opened on the side wall of the fixed block 13 in the area between the two sets of fixed storage plates 12. The adjustment groove 15 penetrates the corresponding wall surface of the fixed block 13 and communicates with the interior of the fixed block 13. The side of the adjustment plate 16 near the fixed block 13 passes through the adjustment groove 15 and is connected to the fixed plate 17.
[0049] In this embodiment, the adjusting plate 16 and the fixed plate 17 are connected to each other so that when the adjusting block 14 drives the fixed plate 17 to rotate, it can drive the adjusting plate 16 to move, thereby effectively driving the folding arc plate 20 and the cleaning block 22 on the folding arc plate 20 to move and complete the shielding and cleaning of the aeration head 9.
[0050] Example 2:
[0051] like Figure 7 As shown, a prefabricated integrated sewage treatment device includes active plates 8. The number of active plates 8 is the same as the number of aeration heads 9. The active plates 8 are evenly spaced on the side wall of the rotating shaft 5.
[0052] In this implementation scheme, the same number of active plates 8 as the aeration heads 9 can effectively drive the cleaning components on multiple sets of aeration heads 9 to synchronously cover and clean the aeration heads 9 during operation.
[0053] In this implementation scheme, when a set of active plates 8 is installed, a single set of active plates 8 will sequentially trigger the cleaning components on the aeration heads 9, so that the cleaning components will sequentially cover and clean the aeration heads 9, thereby effectively reducing the impact on microorganisms and the aeration system. This ensures that the decrease in dissolved oxygen concentration in the aerobic tank during the cleaning process is gradual and has little impact on the survival environment of microorganisms.
[0054] In this implementation scheme, when the number of active plates 8 is the same as the number of aeration heads 9, multiple sets of active plates 8 will simultaneously trigger the cleaning components, so that the cleaning components will simultaneously cover and clean multiple sets of aeration heads 9, thereby efficiently cleaning the aeration heads 9. At the same time, in some wastewater treatment processes that are not very sensitive to fluctuations in dissolved oxygen concentration or in systems with strong microbial adaptability, this simultaneous cleaning method can give full play to its high efficiency.
[0055] Working principle and usage process of this utility model:
[0056] In operation, wastewater is transferred to the anaerobic chamber for anaerobic treatment. The treated wastewater is then transferred to the aerobic chamber 4, where aeration and stirring are activated to induce an aerobic reaction. The treated wastewater is then transferred to the secondary sedimentation chamber. After completing its work in the secondary sedimentation chamber, the wastewater is pumped to a designated area. During the aerobic reaction, the slow rotation of the stirring device 3 causes the active plate 8 to intermittently contact the driven plate 11. When pressed, the driven plate 11 causes the adjusting block 14 to rotate, which in turn causes the fixing plate 17 inside the fixing block 13 to rotate the adjusting plate 16 inside the mounting housing 10. This causes the adjusting plate 16 to extend and expand the folded arc plate 20 inside the fixing and storage plate 12, thereby effectively allowing the cleaning block 22 on the mounting housing 10 to clean the aeration head 9. When the active plate 8 is separated from the driven plate 11, the fixing plate 17 will return through the torsion spring 19, thereby causing the adjusting plate 16 and the folded arc plate 20 to reset.
[0057] When the rotating shaft 5 drives the stirring blades 6 to slowly stir inside the aerobic chamber 4, the active plate 8 at the bottom of the rotating shaft 5 can effectively contact and squeeze the driven plate 11, thereby effectively cleaning the aeration head 9 and greatly reducing the interference of impurities inside the sewage on the aeration head 9.
[0058] By setting cleaning blocks 22 on the folding corners of the folded arc plate 20, the spaced folded arc plates 20 can effectively increase the interval space for cleaning the aeration head 9, so that the same area on the aeration head 9 can be effectively cleaned multiple times, greatly improving the cleaning efficiency of the aeration head 9.
[0059] When the cleaning component cleans the aeration head 9, it will temporarily obscure the aeration head 9, creating a localized area with a low dissolved oxygen concentration around the obscured area. This localized dissolved oxygen gradient can guide the directional movement of microorganisms. Microorganisms are oxygen-attracting, and under the stimulation of this dissolved oxygen gradient, they will move towards the area with a higher dissolved oxygen concentration, thereby promoting the redistribution of microorganisms in the aerobic tank and greatly improving the aerobic reaction effect of the wastewater inside the aerobic chamber 4.
[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
