Description

Technical Field

[0001] This utility model relates to the field of new energy application technology, specifically to a rural solar biogas comprehensive utilization device. Background Technology

[0002] Comprehensive utilization of biogas, also known as "three-biogas utilization," refers to the technical measures that integrate biogas, biogas slurry, and biogas residue resources for agricultural production, aiming to reduce production costs and improve economic efficiency. This technology uses biogas as a link to build an ecological cycle model, covering planting, breeding, and processing, involving diverse scenarios such as energy substitution, fertilizer application, and integrated crop-livestock farming. Through optimized equipment adaptation and operational standards, this technology is gradually maturing and being applied; the biogas digester is one such device.

[0003] Existing rural solar biogas integrated utilization devices suffer from low fermentation efficiency. Due to the lack of an efficient stirring structure, materials in the biogas digester are prone to stratification and sedimentation, resulting in insufficient contact between microorganisms and substrates, leading to low and unstable biogas production. On the other hand, the transmission system design is unreasonable. Most devices do not have an integrated transmission structure, and functions such as stirring and mixing rely on multiple independent drive sources. This not only increases the complexity of the equipment but also leads to high energy consumption, which contradicts the energy-saving requirements of rural solar power supply. Especially when there is insufficient sunlight, the pressure on the battery power supply increases sharply, which can easily cause equipment operation to be interrupted. Utility Model Content

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] Example 1

[0025] like Figure 1-5As shown, this utility model provides a rural solar biogas comprehensive utilization device, including a biogas digester 1 and a gas storage tank 2. An inlet pipe 201 connects the biogas digester 1 and the gas storage tank 2. An inlet pipe 101 and a discharge pipe 102 are connected to the outer wall of the biogas digester 1. Several rotating holes 103 are provided at the top, and a rotating rod 6, a first spiral stirring rod 801, and a second spiral stirring rod 802 are rotatably connected to each of the rotating holes 103. A stirring blade 7 is fixedly installed at the bottom of the rotating rod 6. A protective cover 3 is fixedly installed at the top of the biogas digester 1, and an installation frame 4 is fixedly installed at the top of the protective cover 3. A solar panel 5 is fixedly installed at the top of the installation frame 4. A transmission mechanism 9 is provided inside the protective cover 3, which can drive the rotating rod 6, the first spiral stirring rod 801, and the second spiral stirring rod 802 to rotate. The spiral agitator 1 801 and spiral agitator 2 802 rotate in opposite directions. A storage battery 10 is fixedly installed on the top of the biogas digester 1. A connecting wire 11 connects the storage battery 10 to the solar panel 5. A slot is opened on the top of the mounting frame 4, and the storage battery 10 is placed in the slot. A reinforcing base 202 is fixedly installed on the outer wall of the gas storage tank 2. The air inlet pipe 201 is fixedly connected to the reinforcing base 202. The transmission mechanism 9 includes a motor 901 and a rotating shaft 902. The motor 901 is fixedly installed on the top of the inner wall of the protective cover 3. The two ends of the rotating shaft 902 are fixedly connected to the rotating rod 6 and the output end of the motor 901, respectively. Valves are fixedly installed on the outer walls of the feed pipe 101, the discharge pipe 102 and the air inlet pipe 201. The storage battery 10 is electrically connected to the motor 901. Sealing rings are provided at both ends of several rotating holes 103.

[0026] In this embodiment, livestock and poultry manure and crop straw generated from rural farming are fed into the biogas digester 1 through the feed pipe 101. The solar panel 5 absorbs sunlight during the day and stores the converted electrical energy in the battery 10 via the connecting wire 11, providing power to the motor 901. After the motor 901 starts, it drives the rotating shaft 902 to rotate. The rotating shaft 902 directly drives the rotating rod 6 and the bottom stirring blades 7 to rotate, vertically stirring the material at the bottom of the biogas digester 1 to prevent sedimentation. Simultaneously, the gas storage tank 2 collects the biogas produced by the biogas digester 1 through the air intake pipe 201. The reinforcing base 202 strengthens the connection between the air intake pipe 201 and the gas storage tank 2, preventing biogas leakage.

[0027] Example 2

[0028] Based on Example 1, such as Figure 4As shown, in one embodiment, the transmission mechanism 9 further includes a transmission shaft 903 and a synchronous belt 907. The transmission shaft 903 is fixedly connected to the spiral agitator 801. Synchronous pulleys are fixedly sleeved on both the rotating shaft 902 and the transmission shaft 903. The synchronous belt 907 is sleeved on the two synchronous pulleys. A fan blade 908 is fixedly installed on the top of the transmission shaft 903. Two ventilation openings 300 are opened on the outer wall of the protective cover 3. The transmission mechanism 9 also includes a transmission shaft 904, a drive gear 905, and a transmission gear 906. The transmission shaft 904 is fixedly connected to the spiral agitator 802. The drive gear 905 is fixedly sleeved on the rotating shaft 902. The transmission gear 906 is fixedly sleeved on the transmission shaft 904 and meshes with the drive gear 905.

[0029] In this embodiment, the rotating shaft 902 drives the transmission shaft 903 to rotate via the synchronous pulley and synchronous belt 907, causing the spiral stirring rod 801 to rotate clockwise. Simultaneously, the drive gear 905 on the rotating shaft 902 meshes with the transmission gear 906 on the transmission shaft 904, causing the transmission shaft 904 and the spiral stirring rod 802 to rotate counterclockwise, creating convective stirring and making the materials in the biogas digester 1 more evenly mixed. When the transmission shaft 903 rotates, it synchronously drives the fan blades 908 to rotate, expelling hot air from the protective cover 3 through the vent 300, while allowing cool external air to enter and replenish the air, thus dissipating heat from the motor 901 and transmission components. After fermentation is complete, the biogas slurry and biogas residue can be discharged through the discharge pipe 102 for use as fertilizer in farmland.

[0030] The working principle of this rural solar biogas integrated utilization device will be explained in detail below:

[0031] Fermentation raw materials are fed into the biogas digester 1 through the feed pipe 101. The solar panel 5 converts light energy into electrical energy and stores it in the battery 10. The battery 10 supplies power to the motor 901. The motor 901 drives the rotating rod 6 and the bottom stirring blade 7 to rotate through the rotating shaft 902. At the same time, the synchronous belt 907 drives the spiral stirring rod 801 to rotate clockwise. The drive gear 905 meshes with the transmission gear 906 to drive the spiral stirring rod 802 to rotate counterclockwise, realizing three-dimensional stirring of materials to promote microbial fermentation and biogas production. The biogas produced enters the gas storage tank 2 through the air intake pipe 201 for storage. When the transmission mechanism 9 is running, the fan blade 908 rotates with the transmission shaft 903 and cooperates with the ventilation port 300 to dissipate heat inside the protective cover 3. After fermentation is completed, the biogas liquid and biogas residue are discharged through the discharge pipe 102 for use as organic fertilizer, realizing the recycling of energy to fertilizer.

[0032] The present invention has been described in detail above, but modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are considered valid.
