Description

Technical Field

[0001] This utility model relates to the technical field of household biogas production devices, and in particular to a mobile small-scale household biogas production device. Background Technology

[0002] Household small-scale biogas production units are a type of renewable energy system suitable for home use. They typically consist of a fermentation tank, an inlet, and an outlet. They utilize organic matter such as agricultural waste and livestock manure to produce biogas (mainly methane) through anaerobic fermentation. This biogas can be used for cooking, lighting, etc. Meanwhile, the fermented biogas residue and liquid can be used as organic fertilizer. Portable household small-scale biogas production units are lightweight and modular in design compared to traditional biogas devices, allowing for easy relocation to meet the needs of different locations.

[0003] However, during use, the biogas device can only be moved. After the movement, it still cannot be better adapted to the corresponding biogas production operation, and the position of the biogas device cannot be further adjusted or changed. This results in poor convenience when producing biogas, which reduces its practicality in reality and makes it unsuitable for use in different locations.

[0004] Therefore, this application provides a portable, small-scale household biogas production unit to meet the demand. Summary of the Invention

[0005] To overcome the problems in the prior art, this utility model provides a portable, small-scale household biogas production device.

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0016] This utility model discloses a portable household small biogas production device, mainly including a platform 1. The upper surface of the platform 1 is provided with an adjustment component 5. The adjustment component 5 includes a sliding support plate 502, a fixed toothed plate 503, a mounting plate 504, a rotating rod 505, and a gear 506. The lower surface of the sliding support plate 502 is attached to the upper surface of the platform 1. The bottom of the fixed toothed plate 503 is fixedly installed at the center position of the upper surface of the platform 1. The bottom of the mounting plate 504 is fixedly installed to the top of the sliding support plate 502. The outer surface of the rotating rod 505 is rotatably connected to the inner wall of the mounting plate 504. The inside of the gear 506 is fixedly installed to the outer surface of the rotating rod 505. Hand handles 507 are fixedly installed on the outer surfaces of both ends of the rotating rod 505.

[0017] Fixed slide rails 501 are fixedly installed on both sides of the upper surface of the vehicle plate 1. The outer surface of the fixed slide rail 501 is slidably connected to the inner wall of the bottom end of the sliding support plate 502. The outer surface of the gear 506 meshes with the upper surface of the fixed gear plate 503, and the front and rear sides of the gear 506 are in contact with the opposite sides of the two sets of mounting plates 504.

[0018] The upper surface of the sliding support plate 502 is provided with a fermentation component 4, which includes a fermentation tank 401, a metal tile 402, a feed pipe 404, and a discharge pipe 405. The bottom of the fermentation tank 401 is fixedly installed on the upper surface of the sliding support plate 502, the inner ring of the metal tile 402 is fixedly installed on the outer surface of the fermentation tank 401, the outer surface of one end of the feed pipe 404 is fixedly installed on the inside of the fermentation tank 401, and the outer surface of one end of the discharge pipe 405 is fixedly installed on the inside of the fermentation tank 401.

[0019] When the rotating rod 505 rotates, it drives the gear 506 to rotate. The gear 506 rolls on the fixed toothed plate 503, thereby driving the sliding support plate 502 to slide on the carriage 1. Since the bottom of the fermentation tank 401 is fixedly installed with the upper surface of the sliding support plate 502, the outer surface of one end of the feed pipe 404 is fixedly installed with the inside of the fermentation tank 401, and the outer surface of one end of the discharge pipe 405 is fixedly installed with the inside of the fermentation tank 401, when the sliding support plate 502 slides along the fixed slide rail 501, it drives the fermentation tank 401, the feed pipe 404 and the discharge pipe 405 to move synchronously. This achieves the adjustment of the position of the fermentation tank 401, the feed pipe 404 and the discharge pipe 405 relative to the carriage 1, and achieves the effect of position adjustment through simple rotation operation, which is convenient for users to adjust the position of the relevant components of the device according to actual needs. By fixing handles 507 to the outer surfaces of both ends of the rotating rod 505, a force point is provided for the user to operate the rotating rod 505, which makes it convenient for the user to rotate the rotating rod 505 to achieve the adjustment function and improves the ease of use of the device.

[0020] Both sides of the bottom of the vehicle platform 1 are equipped with movable wheels 2, and a handrail 3 is fixedly installed on the left side of the upper surface of the vehicle platform 1. This structure enables the entire mobile household small biogas production device to move flexibly, so that users can move the device to different locations according to actual needs, thereby improving the convenience of use and site adaptability of the device.

[0021] The outer surface of the fermenter 401 is provided with a heat insulation layer 403. During use, the polyurethane foam material in the heat insulation layer 403 has a low thermal conductivity, which can effectively prevent heat from being conducted outward through the tank wall. In low-temperature environments, it can maintain the temperature inside the tank and reduce heat loss. In high-temperature environments, it can also prevent the temperature inside the tank from becoming too high. This achieves the effect of maintaining a stable temperature inside the fermenter 401, creating good temperature conditions for biogas fermentation, and improving fermentation efficiency and gas production.

[0022] Limiting holes 8 are provided at the four corners inside the vehicle plate 1. A counterweight slot 6 is provided on the left side of the upper surface of the vehicle plate 1, and a counterweight slot 7 is provided on the right side of the upper surface of the vehicle plate 1. Users can place counterweights in the corresponding counterweight slots according to the center of gravity requirements of the device under different usage conditions, thereby achieving the effect of adjusting the overall center of gravity of the device and keeping the device balanced during movement or use.

[0023] Working process: During use, the user pushes the cart 1 as a whole to move using the handrail 3 and the moving wheels 2; the adjustment component 5 is used to adjust the position of the fermentation tank 401. Turning the handle 507 drives the gear 506 to mesh with the fixed toothed plate 503, so that the sliding support plate 502 slides along the fixed slide rail 501, thereby adjusting the position of the fermentation tank 401 to adapt to the site layout requirements; counterweight slot 1 6, counterweight slot 2 7 and limiting hole 8 can be fitted with counterweight blocks and fixing bolts to further enhance the stability of the device when placed. During fermentation, the user feeds organic waste such as livestock and poultry manure and straw into the fermentation tank 401 through the feed pipe 404. Under anaerobic conditions, microorganisms decompose the organic matter to produce biogas (mainly methane), which is temporarily stored on the top of the fermentation tank 401. During fermentation, the metal tile 402 and the insulation layer 403 maintain the temperature inside the tank and improve fermentation efficiency. The biogas produced can be piped out for cooking or lighting, while the biogas liquid and biogas residue are discharged through the discharge pipe 405 as fertilizer.

[0024] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
