Description

Technical Field

[0001] This utility model belongs to the field of microbial culture technology, and in particular relates to a microbial culture device for industrial wastewater treatment. Background Technology

[0002] Against the backdrop of accelerated industrialization, the total discharge of industrial wastewater continues to rise. Its complex composition and high pollutant concentration pose severe challenges to treatment technologies. As the core equipment for biological treatment of industrial wastewater, microbial culture devices degrade organic pollutants into harmless substances through microbial metabolism, playing a key role in the field of environmental protection. However, with increasingly stringent environmental standards, the limitations of traditional microbial culture devices in terms of treatment efficiency, energy consumption control, and ease of maintenance are becoming increasingly apparent, necessitating technological innovation to adapt to the needs of industry development.

[0003] Currently, most common industrial wastewater treatment microbial cultivation devices adopt an aeration structure. Their technical principle is based on the activated sludge process or biofilm process. Such devices usually consist of a reaction tank, an aeration system, a stirring component, and inlet and outlet pipes. The aeration system delivers oxygen to the reaction tank through blowers and aeration heads to provide the metabolic environment required by aerobic microorganisms. The stirring component promotes thorough mixing of wastewater and microorganisms through mechanical stirring, thereby improving mass transfer efficiency. However, the stirring components of existing devices are mostly single rotating structures, and the aeration heads generally adopt a fixed connection design. The overall operation relies on fixed parameter control and lacks dynamic adaptability to complex water quality changes.

[0004] In existing technologies, traditional mixing components struggle to effectively handle sludge and viscous substances adhering to the inner walls of reaction tanks during operation. Due to the lack of targeted inner wall cleaning structures, suspended solids, colloids, and viscous substances produced by microbial metabolism in industrial wastewater easily form stubborn deposits on the inner walls. This not only reduces the effective volume of the reaction tank but also creates "dead volume" areas, hindering normal fluid flow and reducing mixing uniformity. Furthermore, the presence of these deposits reduces heat and mass transfer efficiency, increases mixing resistance, and consequently leads to increased energy consumption and reduced treatment efficiency. Frequent manual cleaning also increases maintenance costs and downtime. Therefore, a microbial cultivation device for industrial wastewater treatment is proposed to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a microbial culture device for industrial wastewater treatment, which aims to solve the problems in the prior art where sludge and sticky substances easily adhere to the inner wall of the reaction tank, resulting in reduced effective volume, uneven mixing, and increased energy consumption.

[0006] The technical solution of this utility model is implemented as follows: a microbial culture device for industrial wastewater treatment includes a reaction tank, an aerator is slidably connected inside the reaction tank, and a stirring assembly is provided inside the reaction tank.

[0007] The stirring assembly includes a fixed plate, one side of which is fixedly connected to the top of the reaction tank. A motor is fixedly connected inside the fixed plate, and a transmission rod is fixedly connected to the output end of the motor. Multiple stirring rods are fixedly connected to the outer wall of the transmission rod, and each stirring rod has multiple holes and slots inside. A connecting rod is fixedly connected to the outer wall of the transmission rod, and multiple springs are provided on one side of the connecting rod. One end of each spring is fixedly connected to the side wall of the connecting rod, and the other end is fixedly connected to a scraper. One side of the scraper contacts the inner wall of the reaction tank, and the scraper is made of rubber. The outer wall of the aerator is provided with symmetrical disassembly components.

[0008] Optionally, the disassembly assembly includes a connecting block and a fixing frame, with one side of the connecting block fixedly connected to the outer wall of the aerator and one side of the fixing frame fixedly connected to the bottom of the connecting block.

[0009] Optionally, the fixing frame is slidably connected inside the reaction tank, and the reaction tank has multiple slots inside.

[0010] Optionally, a compression plate is fixedly connected inside the fixing frame, and a shrink rod is fixedly connected to both sides of the compression plate.

[0011] Optionally, a transmission disc is fixedly connected to the other end of each retractable rod, and a pull block is fixedly connected to the outer wall of each transmission disc.

[0012] Optionally, the pull block is slidably connected inside the fixed frame, and a locking post is fixedly connected to one side of the transmission disc.

[0013] Optionally, the engaging post engages with the slot, and the outer wall of the retractable rod is provided with a spring.

[0014] Optionally, one end of the spring is fixedly connected to the side wall of the transmission disc, and the other end is fixedly connected to the side wall of the extrusion disc.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the motor drives the transmission rod to move, and the groove reduces the resistance of the stirring rod during stirring, while increasing the flow of liquid. The movement of the transmission rod further drives the connecting rod to move synchronously, so that the scraper scrapes against the inner wall of the reaction tank, thereby achieving the effect of quickly scraping the residue on the inner wall of the reaction tank. This solves the problems of reduced effective volume, uneven mixing and increased energy consumption caused by residue adhesion, and improves wastewater treatment efficiency and equipment operation stability.

[0017] 2. In this utility model, by pressing the two pull blocks simultaneously, the retracting rod retracts synchronously. The retraction of the retracting rod drives the locking column to disengage from the slot, thereby unlocking the aerator and achieving the effect of quick installation and disassembly. This solves the problems of time-consuming maintenance, easy clogging, and need for shutdown cleaning of traditional fixed aerators, and improves equipment maintenance efficiency and the operational stability of the aeration system.

[0025] 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.

[0026] Reference Figures 1-3An embodiment of this utility model is provided: a microbial culture device for industrial wastewater treatment, including a reaction tank 1, an aerator 2 slidably connected inside the reaction tank 1, the aerator 2 continuously releases gas to ensure that the microorganisms in the reaction tank 1 grow and reproduce under optimal conditions, and a stirring component is provided inside the reaction tank 1 to maintain the uniform distribution of substances in the water and promote the decomposition of wastewater by microorganisms.

[0027] The stirring assembly includes a fixed plate 3, one side of which is fixedly connected to the top of the reaction tank 1 to ensure the stability of the stirring assembly. A motor 4 is fixedly connected inside the fixed plate 3, serving as the power source for the stirring assembly and providing sufficient rotational power. A transmission rod 5 is fixedly connected to the output end of the motor 4. The outer wall of the transmission rod 5 is fixed to the connection points of multiple stirring rods 6, enabling the transmission rod 5 to drive the multiple stirring rods 6 to rotate. Multiple stirring rods 6 are fixedly connected to the outer wall of the transmission rod 5, and each stirring rod 6 has multiple slots 7 inside. These slots 7 help substances in the wastewater react better with microorganisms. To improve gas diffusion efficiency, a connecting rod 8 is fixedly connected to the outer wall of the transmission rod 5. Multiple springs 9 are installed on one side of the connecting rod 8. One end of each spring 9 is fixedly connected to the side wall of the connecting rod 8, and the other end is fixedly connected to a scraper 10. The scraper 10 is used to clean the deposits on the inner wall of the reaction tank 1 to prevent the deposits from affecting the reaction effect. One side of the scraper 10 is in contact with the inner wall of the reaction tank 1. The scraper 10 is made of rubber, which has good elasticity and wear resistance, and can maintain stable performance during high-frequency stirring. The outer wall of the aerator 2 is equipped with symmetrical disassembly components for easy maintenance and cleaning of the equipment.

[0028] Specifically, when the inner wall of the reaction tank 1 of the microbial culture device for industrial wastewater treatment is prone to sludge, sticky substances, or scaling, leading to a reduction in effective volume, uneven mixing, decreased heat and mass transfer efficiency, or increased maintenance costs, the user first places the microorganisms inside the reaction tank 1 to begin the reaction process. Next, the motor 4 drives the transmission rod 5 to rotate, which in turn drives the stirring rod 6. The rotation of the stirring rod 6 achieves thorough mixing of the liquid and microorganisms, increasing reaction efficiency. During the stirring process, the perforated grooves 7 effectively reduce the resistance of the stirring rod 6 during rotation, thereby enhancing the mixing effect. This mechanism not only improves the fluidity of the liquid but also ensures that microorganisms can react uniformly with the liquid, promoting the stability and efficiency of the reaction process. As the transmission rod 5 rotates, the connecting rod 8 also moves synchronously. The movement of the connecting rod 8 causes the scraper 10 to contact the inner wall of the reaction tank 1, and the spring-9 is squeezed to make it elastically deformed, increasing the contact force between the scraper 10 and the inner wall of the reaction tank 1. The friction of the scraper 10 effectively removes residual substances on the inner wall of the reaction tank 1, keeping the inner wall of the reaction tank 1 clean and avoiding the accumulation of impurities, thereby ensuring the cleanliness of the reaction environment and the long-term stable operation of the equipment.

[0029] Reference Figure 4 and Figure 5 The disassembly assembly includes a connecting block 11 and a fixing frame 12. One side of the connecting block 11 is fixedly connected to the outer wall of the aerator 2, and one side of the fixing frame 12 is fixedly connected to the bottom of the connecting block 11. The fixing frame 12 is slidably connected inside the reaction tank 1. Multiple slots 13 are provided inside the reaction tank 1. A squeezing disc 14 is fixedly connected inside the fixing frame 12. Both sides of the squeezing disc 14 are fixedly connected to a shrinking rod 15. The other end of each shrinking rod 15 is fixedly connected to a transmission disc 16. Pull blocks 17 are fixedly connected to the outer wall of each transmission disc 16. The pull blocks 17 are slidably connected inside the fixing frame 12. With this design, the pull blocks 17 can change position as the transmission disc 16 rotates. This drives other components to perform corresponding operations. The pull block 17 is slidably connected inside the fixed frame 12. Each side of the transmission disc 16 is fixedly connected with a locking post 18, which engages with the slot 13 to ensure that the entire disassembly assembly can be firmly installed in the reaction tank 1 without loosening or falling off due to vibration or other external forces. The outer wall of the retraction rod 15 is provided with a second spring 19. The second spring 19 can provide a certain elasticity to ensure the smooth operation of the assembly and extend its service life during use, while providing elastic restoring force for the assembly. One end of the second spring 19 is fixedly connected to the side wall of the transmission disc 16, and the other end is fixedly connected to the side wall of the extrusion disc 14.

[0030] Specifically, when it is necessary to disassemble and maintain aerator 2, the user presses the pull block 17. The pressing force of the pull block 17 causes the transmission disc 16 to slide inside the fixed frame 12. The sliding of the transmission disc 16 causes the contraction rod 15 to contract, thereby squeezing the second spring 19, causing the second spring 19 to undergo elastic deformation and store elastic potential energy. This process also causes the locking column 18 to disengage from the slot 13, successfully unlocking the device. After unlocking, the user can easily disassemble aerator 2, greatly improving the convenience of equipment maintenance and operational efficiency.

[0031] Working Principle: When using this industrial wastewater treatment microbial culture device, the microorganisms are first placed inside the reaction tank 1 by personnel. Then, the motor 4 drives the transmission rod 5 to rotate, which in turn drives the stirring rod 6 to rotate. The stirring rod 6 mixes the liquid and microorganisms. Simultaneously, the perforated groove 7 reduces the resistance during the rotation of the stirring rod 6, further enhancing the mixing effect and increasing the fluidity of the liquid. While the transmission rod 5 rotates, it also drives the connecting rod 8 to move synchronously. The movement of the connecting rod 8 causes the scraper 10 to contact the inner wall of the reaction tank 1, thereby compressing the spring 9 and causing it to elastically deform, allowing the scraper 10 to move more... The scraper 10 is in good contact with the inner wall of the reaction tank 1. The friction of the scraper 10 scrapes away the residual material on the inner wall of the reaction tank 1. When it is necessary to disassemble and maintain the aerator 2, the user can press the pull block 17 at the same time. Under the action of the pressing, the pull block 17 drives the transmission disc 16 to slide inside the fixed frame 12. The sliding of the transmission disc 16 further drives the contraction rod 15 to contract, thereby squeezing the second spring 19, causing the second spring 19 to undergo elastic deformation and store elastic potential energy. During the movement of the transmission disc 16, it will also drive the locking column 18 to disengage from the locking groove 13 to unlock. After unlocking, the user can quickly disassemble the aerator 2, providing the user with convenient operation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
