Description

Technical Field

[0001] This utility model relates to the field of aerobic fermentation technology, specifically to an aeration fermentation device. Background Technology

[0002] Fermentation tanks are common and crucial facilities in wastewater treatment, organic waste treatment, and bioenergy production, used to achieve the biodegradation and transformation of waste. Aerobic fermentation is a commonly used fermentation method that relies on oxygen supply to sustain the metabolic activities of microorganisms. In traditional aerobic fermentation processes, gas (usually air or oxygen) is typically released into the fermentation tank through aeration devices. The main function of the aeration devices is to provide sufficient oxygen so that microorganisms can successfully oxidize and decompose organic waste. Oxygen is essential for the growth and degradation of waste by aerobic microorganisms; it participates in the oxidation reaction of organic matter and produces final products such as water and carbon dioxide.

[0003] Currently, Chinese utility model patent CN220502802U discloses an aeration device for fermentation tanks, including an aerator installed on the outside of the fermentation tank. The bottom of the fermentation tank has a main pipe mounting groove and several parallel branch pipe mounting grooves connected to the main pipe mounting groove. The air outlet of the aerator has a main aeration pipe arranged in the main pipe mounting groove, and several branch aeration pipes arranged in the branch pipe mounting grooves are connected to the main aeration pipe. Both the main aeration pipe and the branch aeration pipes have several aeration holes. Protective plates are fitted at the upper ends of the main pipe mounting groove and the branch pipe mounting grooves, and the protective plates have several ventilation holes. The advantages of this application compared to the prior art are: this aeration device for fermentation tanks improves the aeration effect, protects the main aeration pipe and branch aeration pipes, and enhances anti-clogging capabilities through design details such as protective plates and nano-flexible hoses. This will help optimize the aerobic microbial metabolic purification effect inside the fermentation tank and improve the treatment performance of the tank.

[0004] Based on the aforementioned patent searches and the findings of existing equipment, while the aforementioned equipment can solve the problem of clogging of the aeration holes in the main and branch aeration pipes by fecal residue, foreign objects, or sludge, leading to poor gas release and affecting the aeration effect, this not only reduces the metabolic activity of microorganisms but may also cause instability in the fermentation process and a decrease in treatment efficiency. Secondly, traditional aeration devices may suffer from uneven gas distribution, potentially leading to oxygen deficiency in some areas and reducing the overall treatment capacity of the fermentation tank. Furthermore, during use, the lack of a cleaning structure means that some fecal residue remains and solidifies around the aeration holes after fermentation, making it difficult for users to clean the area around the aeration holes and thus affecting the aeration effect of the fermentation tank.

[0021] 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.

[0022] like Figures 1 to 3 As shown, the present invention provides an aeration fermentation device, including a fermentation tank 1, an aerator 2, an installation groove 3, an aeration pipe 4, a protective plate 5, and aeration holes 6. The aerator 2 is fixedly installed on the right side of the front side of the fermentation tank 1. The installation groove 3 is opened at the bottom of the inner wall of the fermentation tank 1. The aeration pipe 4 is fixedly installed on the inner wall of the installation groove 3, and one end of the aeration pipe 4 is connected to the output end of the aerator 2. The protective plate 5 is fixedly installed on the inner wall of the installation groove 3, and the aeration holes 6 are opened on the surface of the protective plate 5. A cleaning scraper 7 is movably connected to the inner wall of the fermentation tank 1. The bottom of the cleaning scraper 7 is movably connected to the top of the protective plate 5. A pulling component 8 is fixedly installed on the top of the left side of the fermentation tank 1, and a cleaning component 9 is fixedly installed on the top of the right side of the fermentation tank 1.

[0023] refer to Figure 1 and Figure 2 The pulling component 8 includes a dual-axis motor 81, which is fixedly installed on the top left side of the fermentation tank 1. The output end of the dual-axis motor 81 is fixedly connected to a rope winding roller 82. A pull rope 83 is provided on the top of the fermentation tank 1. Circular holes 84 are provided on both sides of the top left side of the cleaning scraper 7. One end of the pull rope 83 is fixedly wrapped around the inner wall of the circular hole 84, and the other end of the pull rope 83 is fixedly wrapped around the surface of the rope winding roller 82.

[0024] As a technical optimization of this utility model, by setting up the pulling component 8, the dual-shaft motor 81 can effectively drive the rope winding roller 82 to rotate, so that the rope winding roller 82 can wind up the pull rope 83 and pull the cleaning scraper 7 through the round hole 84, so that the cleaning scraper 7 can move inside the fermentation tank 1, thereby scraping the inner wall of the fermentation tank 1 and the top of the protective plate 5, cleaning the residual fecal residue, and preventing the fecal residue from solidifying and affecting the aeration effect of the aeration hole 6.

[0025] refer to Figure 1 and Figure 2 The cleaning assembly 9 includes a cleaning pump 91, which is fixedly installed on the top right side of the fermentation tank 1. The output end of the cleaning pump 91 is connected to a telescopic pipe 92, and the bottom of the telescopic pipe 92 is connected to a U-shaped pipe 93, which is located on the left side of the cleaning scraper 7.

[0026] As a technical optimization of this utility model, by setting up a cleaning component, the cleaning pump 91 can effectively draw water from the water source and transport the water to the U-shaped pipe 93 through the telescopic pipe 92. The U-shaped pipe 93 can clean the inner wall of the fermentation tank 1, thereby improving the cleaning effect of the cleaning scraper 7.

[0027] refer to Figure 1 and Figure 3 The surface of the U-shaped tube 93 is fixedly fitted with a reinforcing block 10, and the right side of the reinforcing block 10 is fixedly connected to the left side of the cleaning scraper 7.

[0028] As a technical optimization of this utility model, by setting the reinforcing block 10, the cleaning scraper 7 can be effectively fixed to the reinforcing block 10. The reinforcing block 10 can reinforce the U-shaped tube 93, improving the stability of the U-shaped tube 93 during cleaning. At the same time, the cleaning scraper 7 can drive the U-shaped plate to move accordingly.

[0029] refer to Figure 1 and Figure 2 A baffle plate 11 is provided on the left side of the U-shaped tube 93, and electric push rods 12 are fixedly connected to both sides of the right side of the cleaning scraper 7. The output end of the electric push rod 12 is fixedly connected to both sides of the top of the baffle plate 11.

[0030] As a technical optimization of this utility model, by setting the baffle plate 11 and the electric push rod 12, the baffle plate 11 can effectively block the fecal residue, thereby preventing the fecal residue from entering the interior of the U-shaped tube 93 and causing blockage. The electric push rod 12 drives the baffle plate 11 to rise, so that the U-shaped tube 93 and the cleaning scraper 7 can be cleaned.

[0031] refer to Figure 2 and Figure 3 Limiting grooves 13 are provided on both sides of the inner wall of the fermentation tank 1. Limiting blocks 14 are movably connected to the inner wall of the limiting grooves 13. The inner side of the limiting blocks 14 is fixedly connected to both sides of the cleaning scraper 7.

[0032] As a technical optimization of this utility model, by setting the limiting groove 13 and the limiting block 14, the cleaning scraper 7 can effectively drive the limiting block 14 to slide on the inner wall of the limiting groove 13, thereby limiting the cleaning scraper 7, thus improving the stability of the cleaning scraper 7 and preventing the cleaning scraper 7 from tilting or deviating.

[0033] refer to Figure 1 and Figure 2 A cleaning hole 15 is provided on the left side of the fermentation tank 1, and baffles 16 are movably connected to both sides of the inner wall of the cleaning hole 15 by means of a pivot pin.

[0034] As a technical optimization of this utility model, by setting a cleaning hole 15 and a baffle 16, the baffle 16 can be effectively opened from the inside of the cleaning hole 15, and the fecal residue generated during cleaning can be discharged through the cleaning hole 15.

[0035] The working principle and usage process of this utility model are as follows: When aeration is performed in the fermentation tank 1, the user first starts the aerator 2 to deliver gas into the aeration pipe 4. The gas then travels through the aeration pipe 4 to the inside of the mounting slot 3 and is released into the fermentation tank 1 through the aeration holes 6 at the top of the protective plate 5. When the fermentation tank 1 is cleaned after aeration, some fecal residue will remain around the aeration holes 6 and on the inner wall of the fermentation tank 1. The electric push rod 12 is activated to move the baffle plate 11 upwards. At this time, the user starts the dual-shaft motor 81 to drive the rope roller 82 to rotate, causing the rope roller 82 to wind up the pull rope 83 and pull the cleaning scraper 7 through the round hole 84. This causes the cleaning scraper 7 to move to the left inside the fermentation tank 1, thereby cleaning the inner wall and the baffle plate 5. The top of the protective plate 5 is scraped to remove residual fecal sludge, preventing it from solidifying around the aeration holes 6 and affecting the aeration effect. This facilitates cleaning. While cleaning the fermentation tank 1 and the area around the aeration holes 6 using the cleaning scraper 7, the user connects the cleaning pump 91 to the water source to draw water and delivers it to the U-shaped pipe 93 through the telescopic pipe 92. Spraying water around through the U-shaped pipe 93 cleans the inner wall of the fermentation tank 1, thereby improving the cleaning effect of the fermentation tank 1 and the top of the protective plate 5 and increasing the efficiency of fecal sludge removal. Then, the user opens the baffle 16 inside the cleaning hole 15, allowing the wastewater and fecal sludge generated during cleaning to be discharged through the cleaning hole 15, preventing wastewater and fecal sludge from remaining inside the fermentation tank 1.

[0036] In summary, this aeration fermentation device, by incorporating a cleaning scraper 7, a pulling component 8, and a cleaning component 9, effectively enables the pulling component 8 to move the cleaning scraper 7 within the fermentation tank 1. This allows the cleaning scraper 7 to clean the residual manure residue on the top of the protective plate 5, preventing the manure residue from solidifying around the aeration holes 6 and affecting the aeration effect. Simultaneously, the cleaning component 9 cleans the protective plate 5 and the interior of the fermentation tank 1. This solves the problem that, during fermentation, the lack of a cleaning structure leads to some manure residue remaining and solidifying around the aeration holes after use, making it difficult for users to clean the area around the aeration holes and thus affecting the aeration effect of the fermentation tank.
