Abstract
Description
Technical Field
[0001] This utility model relates to the field of bioreactor technology, and in particular to a bioreactor. Background Technology
[0002] Bioreactors play a crucial role in treating agricultural waste, such as crop straw and livestock manure, which contain large amounts of organic matter. When agricultural waste is thoroughly mixed with microorganisms, appropriate amounts of water, and nutrient additives, the microorganisms in the bioreactor can decompose these complex organic compounds into simpler compounds, such as breaking down cellulose and hemicellulose into monosaccharides and proteins into amino acids. Simultaneously, the metabolic activities of the microorganisms release essential nutrients for plant growth, such as nitrogen, phosphorus, and potassium, making them more readily absorbed and utilized by plants.
[0003] Traditional bioreactors have several shortcomings in biological reaction processes such as agricultural waste treatment. For example, aeration systems are prone to clogging, affecting gas distribution and reaction efficiency; the internal structure of the reactor is not conducive to thorough mixing and reaction of materials, resulting in poor treatment outcomes. Therefore, an improved bioreactor is needed to address these issues. Utility Model Content
[0004] This invention provides a bioreactor to solve the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A bioreactor includes a reaction tank, an air pump, and a water pump. Multiple support legs are fixedly connected to the bottom of the reaction tank, and a cover plate is provided on the top of the reaction tank. An air supply pipe is fixedly connected to the output end of the air pump. One end of the air supply pipe is fixedly inserted through the central bottom sidewall of the reaction tank. A rotating pipe is rotatably connected to the end of the air supply pipe extending into the reaction tank via a sealed bearing. Three air outlet pipes are fixedly connected to the sidewall of the rotating pipe. Multiple aeration holes are opened on the sidewall of each air outlet pipe, and a conical mesh is fixedly connected to each aeration hole. Multiple stirring rods are fixedly connected to the sidewall of each air outlet pipe. A water supply pipe is fixedly connected to the output shaft of the water pump, and one end of the water supply pipe extends from the sidewall of the reaction tank into the interior of the reaction tank.
[0007] Preferably, an exhaust pipe is fixedly connected to the cover plate, and a sealing cap is provided at the top of the exhaust pipe.
[0008] Preferably, the side wall of the reaction tank is provided with an observation window, which is made of transparent glass.
[0009] Preferably, both the air outlet pipe and the rotating pipe are made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention achieves a highly efficient and stable biological reaction process. The conical mesh effectively solves the problem of aeration hole blockage.

[0024] Please see Figures 1-6 In this embodiment of the present invention, a bioreactor includes a reaction tank 3, an air pump 1, and a water pump 9. The reaction tank 3 is arranged in a cylindrical shape with an open top. This shape is conducive to the uniform distribution of the mixed liquid and the diffusion of gas in the reaction tank 3. Multiple support legs 16 are fixedly connected to the bottom side of the reaction tank 3. A cover plate 5 is provided on the top of the reaction tank 3. The cover plate 5 serves to seal the reaction tank 3, prevent external impurities from entering, and ensure a relatively stable reaction environment. An exhaust pipe 7 is fixedly connected to the cover plate 5. A sealing cap 6 is provided at the top of the exhaust pipe 7. During the reaction, when it is necessary to discharge the gas generated by the reaction, the sealing cap 6 can be opened. During normal reaction, the sealing cap 6 remains closed to prevent gas leakage and the entry of outside air from affecting the reaction.
[0025] Please see Figure 4 , Figure 5 and Figure 6 The output end of the air pump 1 is fixedly connected to the air supply pipe 2. One end of the air supply pipe 2 is fixedly connected through the central bottom side wall of the reaction tank 3. The end of the air supply pipe 2 extending into the reaction tank 3 is rotatably connected to the rotating pipe 12 through the sealed bearing 15. Three air outlet pipes 11 are fixedly connected to the side wall of the rotating pipe 12. Both the air outlet pipe 11 and the rotating pipe 12 are made of stainless steel, which has good corrosion resistance and strength and can adapt to the complex environment inside the reaction tank 3. Multiple aeration holes 13 are opened on the side wall of each air outlet pipe 11. A conical mesh 14 is fixedly connected to each aeration hole 13. The conical mesh 14 can not only effectively block large particles of impurities in the mixed liquid from entering the aeration hole 13 and prevent the aeration hole 13 from being blocked, but also make the gas more evenly dispersed in the mixed liquid and improve the aeration efficiency. Multiple stirring rods 10 are fixedly connected to the side wall of the air outlet pipe 11. The output shaft of the water pump 9 is fixedly connected to the water supply pipe 8. One end of the water supply pipe 8 extends from the side wall of the reaction tank 3 into the interior of the reaction tank 3.
[0026] Specifically, the side wall of the reaction tank 3 is provided with an observation window 4, which is made of transparent glass. The reaction process can be observed through the observation window 4, and the aeration rate of the air pump 1 and the water supply of the water pump 9 can be adjusted in a timely manner according to the reaction conditions (such as the generation of bubbles, changes in the color of the mixed liquid, etc.).
[0027] The working principle of this utility model is as follows:
[0028] In the biological reaction process, agricultural waste and other reaction raw materials are first mixed with appropriate amounts of water and nutrient additives and then added to the reaction tank 3. The air pump 1 is then started, which delivers air or other gases through the air supply pipe 2 to the rotating pipe 12, and then disperses them into the mixed liquid through the aeration holes 13 and conical mesh 14 of the air outlet pipe 11. Simultaneously, when the airflow exits from the aeration holes 13, it drives the air outlet pipe 11 to rotate around the rotating pipe 12. The rotation of the air outlet pipe 11 drives multiple stirring rods 10 to stir the mixed liquid, ensuring sufficient contact between the reactants and microorganisms.
[0029] Water pump 9 supplies water to reaction tank 3 through water supply pipe 8 as needed for the reaction, adjusting the moisture content of the mixture. Operators can observe the reaction process through observation window 4 and adjust the aeration rate of air pump 1 and the water supply rate of water pump 9 as needed. Gases generated during the reaction are discharged through exhaust pipe 7; when venting is required, the sealing cover 6 can be opened.
[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
