Description

Technical Field

[0001] The utility model relates to the technical field of biological fermentation, in particular to a solar-powered biological decomposition and digestion device. Background Art

[0002] Biodegradation and fermentation is a process that uses microorganisms such as bacteria, fungi or yeast to convert organic matter into simpler compounds. This process usually involves the degradation of organic matter, producing carbon dioxide, water and organic waste. Biodegradation and fermentation are widely present in nature and are also widely used in many industrial and environmental fields.

[0003] A search revealed a solar biodegradation and digestion device with publication number CN206632111U, comprising a housing, a feed port and a controller being arranged on the left side of the housing from top to bottom, a solar heat absorbing plate being arranged on the top of the housing, an ultraviolet sterilization lamp being fixedly mounted on the inner top of the housing, and an air purification device, a decomposition plate, and a water collection tank being arranged inside the housing and below the ultraviolet sterilization lamp. The device absorbs heat energy generated by the sun to decompose and digest the material, thereby achieving energy-saving and environmental protection effects and reducing environmental pollution. The provision of a vibration plate can evenly distribute the material and improve the decomposition efficiency. However, the above technical solution still has the following deficiencies in actual use:

[0004] In this solution, the solar heat absorbing plate acts on the top of the casing, and its heating range inside the casing is limited, which means that the temperature difference inside the casing is large, which in turn leads to a large temperature difference between the material at the top layer and the material at the bottom layer, affecting the decomposition and digestion efficiency of the material. Although a vibration plate is set at the bottom of the decomposition plate in this solution, the biological material will produce water during the decomposition process, and the materials will stick together. Especially when decomposing larger materials, it is difficult for the biological material at the bottom layer to move to the upper layer to be heated under the action of the vibration plate, which will affect the overall decomposition and digestion efficiency of the biological material and the decomposition effect of the bottom material.

[0005] Therefore, it is necessary to design a solar biodegradation and digestion device to solve the above problems. Utility Model Content

[0025] Reference Figure 1 and Figure 4 The stirring assembly includes a driving shaft 6 rotatably connected to the bottom of the decomposition tank 1, and two connecting rods 9 are fixedly connected to the side wall of the driving shaft 6. A rotating shaft 7 is connected between the two connecting rods 9 for common rotation. A plurality of stirring plates 8 are fixedly connected to the side wall of the rotating shaft 7. The stirring assembly also includes a driving member, which is used to drive the rotation of the driving shaft 6 and the rotating shaft 7. The stirring plates 8 can break up the accumulated and bonded biological materials, so that the materials are fully heated, thereby ensuring the decomposition quality of the biological materials.

[0026] Reference Figure 1 and Figure 4 The driving part includes a motor 15 fixedly connected to the decomposition tank 1, and the motor 15 is electrically connected to the solar photovoltaic device 2. Using the solar photovoltaic device 2 to power the hot air blower 4 and the motor 15 can save energy. The end of the output shaft of the motor 15 is axially connected to the drive shaft 6. The inner side of the decomposition tank 1 is fixedly connected with an inner ring gear 16. A gear 17 is fixedly sleeved on the rotating shaft 7, and the gear 17 is engaged with the inner ring gear 16. Under the action of the motor 15, the rotating shaft 7 can rotate around the drive shaft 6. Under the transmission action of the gear 17 and the inner ring gear 16, the rotating shaft 7 will also rotate on its own, so that the stirring plate 8 can fully stir the biological material, so that the material can be fully and evenly heated, thereby improving the overall decomposition and digestion efficiency of the biological material.

[0027] Reference Figure 1-3The heating assembly includes an air inlet pipe 10, which is embedded in the drive shaft 6 and one of the connecting rods 9. One end of the air inlet pipe 10 is connected to the air outlet end of the hot air blower 4. A heating pipe 11 is embedded in the rotating shaft 7 and all the stirring plates 8. One end of the heating pipe 11 is connected to the other end of the air inlet pipe 10. A connecting pipe 13 is provided in the drive shaft 6 and the other connecting rod 9.

The hot air in the ventilation pipe 5 and the hot air in the heating pipe 11 will re-enter the air inlet end of the hot air blower 4, forming a circulation of hot air, which can reduce the loss of heat energy in the air and improve the heating efficiency. By setting the heating component, the inside of the biological material in the decomposition tank 1 can be fully heated, which is conducive to reducing the temperature difference between the materials, ensuring the consistency of biological decomposition, and improving the overall decomposition efficiency.

[0028] Reference Figure 1 The cross-section of the heating tube 11 located in the stirring plate 8 is a U-shaped structure, which can increase the contact area between the heating tube 11 and the stirring plate 8, thereby increasing the heating range of the heating tube 11 on the biological material, which is beneficial to the growth of microorganisms and thus improves the efficiency of biological decomposition and digestion.

[0029] Reference Figure 1 The vent pipe 5 has a spiral structure, which can increase the contact area between the vent pipe 5 and the decomposition tank 1 and ensure the heating and heat preservation effect of the vent pipe 5 on the decomposition tank 1.

[0030] The specific working principle of this utility model is as follows:

[0031] During operation, the solar photovoltaic device 2 converts solar energy into electrical energy and supplies it to the motor 15 and the hot air blower 4. The hot air blower 4 heats the air and sends it into the ventilation pipe 5. The ventilation pipe 5 heats the tank wall of the decomposition tank 1. This can reduce the temperature difference in the decomposition tank 1 and ensure the consistency of the decomposition and digestion of the biological material. Secondly, it can keep the tank at a constant temperature, which is conducive to the growth of microorganisms and thus ensure the fermentation effect of the material.

[0032] Secondly, another part of the heated air can enter the air inlet pipe 10 and then enter the interior of the heating pipe 11. Since the heating pipe 11 and the air inlet pipe 10 are located in the center of the biological material, this can increase the heating range of the device, reduce the temperature difference between the materials, and improve the overall decomposition efficiency of the biological material. After the hot air in the ventilation pipe 5 finishes heating the tank wall, it will re-enter the air inlet end of the hot air blower 4. Similarly, the hot air in the heating pipe 11 will also enter the air inlet end of the hot air blower 4 through the connecting pipe 13 and the air outlet pipe 14, thus forming a circulation of hot air, which can reduce the loss of heat energy in the air.

[0033] While the hot air blower 4 is working, the rotation of the output shaft of the motor 15 will drive the drive shaft 6 to rotate, so that the connecting rod 9, the rotating shaft 7 and the stirring plate 8 rotate around the drive shaft 6. The rotating shaft 7 and the stirring plate 8 will stir the biological material in the decomposition tank 1 during the rotation process, so that the device can heat the material evenly. Furthermore, the rotation of the rotating shaft 7 will drive the gear 17 to rotate together. Under the action of the inner ring gear 16, the rotating shaft 7 will rotate around the drive shaft 6 while also rotating on its own. In this way, the stirring plate 8 can fully stir the biological material, so that the material can be fully and evenly heated, which is more conducive to the thoroughness and consistency of the decomposition and digestion of the material, and improves the decomposition efficiency.
