Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste, and in particular to a stepwise fermentation hydrogen production reactor for kitchen waste. Background Technology

[0002] Food waste refers to the waste generated in daily life, food processing, catering services, and institutional catering. Food waste is characterized by its large volume and complex composition. If not treated promptly, it will not only pollute the environment but also waste its resources. Traditional methods of food waste disposal often involve simple landfilling or incineration, which not only fails to fully utilize the resources in the waste but may also cause secondary pollution. Therefore, how to efficiently treat food waste and achieve resource reuse has become an urgent problem to be solved. The stepwise fermentation hydrogen production reactor for food waste is a device designed to address these issues. Through stepwise fermentation of food waste, it can effectively extract hydrogen resources while simultaneously achieving the harmless treatment of the waste.

[0003] In the process of treating food waste through a fermentation hydrogen production reactor, uneven mixing during the stirring process can easily occur, making it difficult to achieve an ideal level of mixing of the food waste inside the reactor. This results in some of the waste not being fully fermented, thus affecting the hydrogen production efficiency, leading to resource waste and poor treatment results. Therefore, most methods use forced stirring or increasing the number of stirrers to improve the mixing effect. However, this method often increases the complexity of the equipment and energy consumption, and the results are not always ideal. Utility Model Content

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] The following describes an embodiment of the present invention: a stepwise fermentation reactor for hydrogen production from kitchen waste.

[0024] like Figures 1-4 As shown, the stepwise fermentation hydrogen production reactor for kitchen waste according to this utility model includes: reactor body 1 and stirring mechanism 2.

[0025] The stirring mechanism 2 includes a mounting bracket 21, a cylinder 22, a connecting rod 23, a stirring impeller 24, a first gear 25, a second gear 26, and a motor 27.

[0026] The mounting bracket 21 is mounted on the reactor body 1, the cylinder 22 is mounted on the mounting bracket 21, the connecting rod 23 is connected to the output end of the cylinder 22, the stirring impeller 24 is mounted on one end of the connecting rod 23, the first gear 25 is mounted on the outer wall of the connecting rod 23, the second gear 26 is meshed with the first gear 25, and the second gear 26 is connected to the rotating shaft of the motor 27.

[0027] Specifically, cylinder 22, driven by air pressure, can drive connecting rod 23 to reciprocate vertically, allowing the stirring impeller 24 to be adjusted in height within tank 13. When motor 27 starts, the meshing of second gear 26 and first gear 25 drives connecting rod 23 to rotate circumferentially, causing stirring impeller 24 to undergo three-dimensional composite motion within tank 13. This structural design enables multi-directional mixing of materials and allows for precise control of stirring depth by adjusting the stroke of cylinder 22, ensuring thorough mixing of kitchen waste within tank 13. This mixing method not only improves mixing efficiency but also significantly enhances mixing uniformity, increases hydrogen production efficiency, and avoids problems such as dead zones and material accumulation.

[0028] In one embodiment of this application, such as Figure 3 As shown, a cleaning mechanism 3 is provided on the outer wall of the reactor body 1.

[0029] The cleaning mechanism 3 includes a water tank 31, an inlet pipe 32, a water pump 33, an outlet pipe 34, a water delivery pipe 35, a nozzle 36, a connecting plate 37, a fixing rod 38, and a scraper 39.

[0030] The water storage tank 31 is installed on the reactor body 1, the water inlet pipe 32 is installed on the outer wall of the water storage tank 31, the input end of the water pump 33 is connected to the other end of the water inlet pipe 32, the water outlet pipe 34 is connected to the output end of the water pump 33, the water delivery pipe 35 is connected to the other end of the water outlet pipe 34, multiple nozzles 36 are equidistantly arranged on the outer wall of the water delivery pipe 35, the connecting plate 37 is installed on the outer wall of the connecting rod 23, the fixing rod 38 is installed on the outer wall of the connecting plate 37, and the scraper 39 is installed at one end of the fixing rod 38.

[0031] Specifically, when the reactor interior needs cleaning, the water pump 33 draws cleaning liquid from the water storage tank 31 through the inlet pipe 32 and pressurizes and delivers the cleaning liquid to the outlet pipe 34 through its output end. The outlet pipe 34 then guides the cleaning liquid into the water supply pipe 35, which in turn sprays the cleaning liquid evenly onto the inner wall of the reactor body 1 through multiple nozzles 36. At the same time, the scraper 39, driven by the fixed rod 38, scrapes along the inner wall of the reactor body 1, effectively removing residues and dirt adhering to the reactor inner wall. This cleaning mechanism 3 design not only improves cleaning efficiency but also ensures the cleanliness of the reactor body 1, providing a good environment for the subsequent fermentation and hydrogen production process. It avoids performance degradation or malfunction of the reactor body 1 due to improper human operation or incomplete cleaning, greatly reducing the labor intensity of manual cleaning and improving work efficiency.

[0032] In one embodiment of this application, such as Figure 1 As shown, the reactor body 1 includes a base 11, multiple support legs 12, a tank body 13, and a tank cover 14.

[0033] Multiple support feet 12 are respectively set on the base 11, the tank body 13 is set on the support feet 12, and the tank cover 14 is set on the tank body 13.

[0034] Specifically, the tank body 13 and the tank cover 14 are sealed together by bolts to ensure the airtightness of the reactor body 1. The design of the base 11 allows the entire reactor body 1 to be placed stably on the ground, while multiple support feet 12 provide additional support and stability to prevent the tank body 13 from shaking or tilting during operation. The tank body 13 is usually made of corrosion-resistant and high-temperature-resistant materials to adapt to the complex environment in the process of hydrogen production from food waste fermentation.

[0035] In one embodiment of this application, such as Figure 4 As shown, each of the multiple nozzles 36 has a dustproof mesh 4 installed inside.

[0036] Understandably, the dustproof net 4 can effectively prevent dust and impurities accumulated inside the main body 1 of the purification equipment from entering the nozzle 36 during long-term use, causing the nozzle 36 to become clogged or damaged, affecting the cleaning effect and normal operation of the equipment. The material of the dustproof net 4 also needs to be selected as corrosion-resistant and high-temperature resistant to ensure that it can operate stably for a long time in the harsh working environment inside the reactor body 1.

[0037] In one embodiment of this application, such as Figure 2 As shown, cylinder 22 and connecting rod 23 form a telescopic structure.

[0038] Understandably, the telescopic structure formed by the cylinder 22 and the connecting rod 23 allows the stirring impeller 24 to be adjusted in height according to different stirring requirements.

[0039] In one embodiment of this application, such as Figure 2 As shown, the motor 27 and the second gear 26 form a rotating structure.

[0040] Understandably, the rotating structure formed by the motor 27 and the second gear 26 ensures that the stirring impeller 24 can rotate circumferentially within the tank 13, thereby further enhancing the mixing effect of the materials.

[0041] In one embodiment of this application, such as Figure 2 As shown, one end of the connecting rod 23 is connected to multiple stirring impellers 24.

[0042] Understandably, the design of connecting one end of the connecting rod 23 to multiple stirring impellers 24 can increase the stirring area and make the stirring more uniform. Especially when processing a large amount of food waste, this design can significantly improve the stirring efficiency and ensure that each part of the material can be fully mixed, thereby improving the uniformity and efficiency of hydrogen production.

[0043] In summary, the stepwise fermentation hydrogen production reactor for kitchen waste of this invention, through the setting of the stirring mechanism and the coordinated work of the cylinder and motor, enables the stirring impeller to form a three-dimensional composite motion within the tank. This not only improves the stirring efficiency and enhances the uniformity of stirring, but also avoids the problems of dead zones and material accumulation, thereby improving the hydrogen production efficiency. At the same time, the design of the cleaning mechanism allows for a comprehensive and thorough cleaning of the reactor interior, ensuring the cleanliness and performance stability of the reactor, and providing a good environment for the subsequent fermentation hydrogen production process.
