Description

Technical Field

[0001] This invention relates to the field of food waste treatment technology, specifically to a mobile, stable, decentralized device for the treatment of food waste. Background Technology

[0002] Currently, the main methods for treating food waste in my country include direct discharge after crushing, incineration, sanitary landfill, feed production, aerobic composting, and anaerobic fermentation. Anaerobic fermentation technology refers to the process where, under anaerobic conditions, food waste, through the combined action of hydrolytic acidifying bacteria, methanogenic bacteria, and other anaerobic or facultative anaerobic bacteria, synthesizes its own cellular material, simultaneously generating water, methane, and carbon dioxide, ultimately achieving the harmlessness, reduction, and resource recovery of food waste. Anaerobic fermentation technology is the most efficient way to convert organic waste into energy.

[0003] Currently, the most common technology is centralized collection and then disposal. However, food waste has a high moisture content and organic matter content, making it prone to spoilage. Long-distance transportation can easily cause leakage, odor, and other environmental problems, especially in hot weather when timely collection is not possible, severely impacting the living environment of residents. In rural areas where residents are scattered and food waste is relatively scarce, centralized collection is costly. Therefore, mobile small-scale biogas production devices can solve these problems, enabling decentralized on-site disposal of food waste.

[0004] Patent No. 201720440982.5, "Mobile Anaerobic Biogas System", discloses an anaerobic digestion unit and a biogas storage unit, mainly for human excrement sludge. The structure is relatively simple and is not suitable for kitchen waste. Kitchen waste needs to be crushed before it can be fermented better. In addition, part of the power of this device needs to be provided by solar energy, and the heating and stirring of the fermentation tank are provided by the biogas system. A single energy system has the problem of system stability.

[0005] Patent No. 200920003440.7, "Mobile Integrated Solar Biogas Generator with Heat Absorption and Insulation," discloses a heat absorption, light transmission, and insulation device installed on the outside of the biogas reactor. However, it also has the problem of unstable energy, especially in the cold winter, when fermentation is difficult to proceed normally.

[0006] Therefore, there is an urgent need for a mobile, stable, decentralized device for the disposal of food waste to solve the aforementioned problems. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) The mobile system for stable decentralized disposal of kitchen waste, through the design of the crushing mechanism, crushes the kitchen waste before fermentation, so that the device can better ferment the kitchen waste and improve the working efficiency of the device.

[0019] (2) This mobile, stable, decentralized device for disposing of kitchen waste utilizes an alarm unit on the fermentation tank, along with a power storage device and an external power supply. When the energy supply is unstable, the power storage device is activated first. Once the fermentation tank's gas production stabilizes, the power storage device is deactivated, and the biogas power generation system is activated simultaneously. When the power storage device reaches its threshold and the biogas system cannot start, the alarm device is activated, the fermentation tank needs to be adjusted, and an external power supply is connected. This provides triple protection for the fermentation process, ensuring normal fermentation operation.

[0020] (3) The mobile system for the stable decentralized disposal of kitchen waste is designed with a reversible motor. During operation, the reversible motor rotates in both forward and reverse directions. The reversible motor is connected to the first upright rod through the first wheel rod, and the second upright rod and the screw are driven to rotate through the second grinding column. This causes the pressure plate to move up and down along the screw inside the pressure cylinder, thereby pressing the kitchen waste above the pressure cylinder into the interior of the anti-splash structure in stages. This allows the kitchen waste to enter the lower part of the cylinder in a regular manner and be crushed, preventing the crushing mechanism from becoming clogged and improving the smoothness of the device's operation.

[0021] (4) The mobile system for the stable decentralized disposal of kitchen waste uses a reversible motor that rotates forward and reverse alternately during operation. This works in conjunction with the blades. When the motor rotates forward, it crushes the kitchen waste, and when it rotates reverse, it stirs the kitchen waste, thus making the kitchen waste more uniform and thorough in its crushing.

[0022] (5) This mobile system for the stable decentralized disposal of kitchen waste, through the design of the anti-splash structure and the pressing operation of the pressure plate, allows the kitchen waste to be pressed into the interior of the anti-splash structure. First, it contacts the upper side rod, thereby pushing the lower end of the upper side rod outward, thus opening the opening of the anti-splash cylinder and allowing the kitchen waste to pass through smoothly. When the side rod loses the pressure of the pressure plate, the presence of the spring shaft will cause the side rod to retract, and at the same time, the internal cutting blade will cut the kitchen waste. The retracted anti-splash structure can also separate the upper and lower parts of the anti-splash structure, thus preventing the waste liquid from splashing out.

[0023] (6) The mobile system for stable decentralized disposal of kitchen waste, through the design of the grinding structure, after the grinding column is driven to rotate by the upright rod, will gradually squeeze the kitchen waste and gradually convey it to the crushing structure below through the design of the spiral thread belt. Through the design of the grinding structure, the kitchen waste is ground and squeezed while being conveyed, thereby improving the crushing efficiency of the device.

[0024] (7) This mobile system for stable decentralized disposal of kitchen waste, through the bottom structure and the liquid level inside the fermentation tank, the waste liquid will gradually flow into the fermentation tank through the slurry outlet pipe, and the biogas generated inside the fermentation tank will be produced through the gas pipe. When the liquid level inside the fermentation tank is too high, the float will float on the liquid surface inside the fermentation tank, thereby pushing the lower column two upward, thereby causing gear two to separate and mesh with gear one, thereby stopping the crushing mechanism from working, avoiding the problem of excessive input of the device and causing waste liquid to enter the gas pipe, thus improving the overflow prevention function of the device.

It is intended for use in agricultural markets.

[0049] Example 6: Please refer to Figure 1Based on Example 1, this invention provides a technical solution: a fermenter 101 with a volume of 3 cubic meters, a processing capacity of 10 kg / d, a fermentation temperature of 35-30℃, and a biogas production of 6 m³ / d. It is suitable for 10 households, particularly in remote rural areas.

[0050] Working principle:

[0051] Step 1: By designing a crushing mechanism, the kitchen waste is crushed before fermentation, enabling the device to ferment the kitchen waste more effectively and improving the device's working efficiency.

[0052] The second step involves using the alarm unit on the fermenter, along with the energy storage device and alarm, and connecting to an external power source. When the energy supply is unstable, the energy storage device will activate first. Once the fermenter's gas production stabilizes, the energy storage device will shut off, and the biogas power generation system will start simultaneously. When the energy storage device reaches its threshold and the biogas system cannot start, the alarm will activate, requiring the fermenter to adjust its fermentation process, and an external power source will be connected. This triple protection system ensures the fermentation process operates normally.

[0053] Step 3: Through the design of the reversing motor 301, the reversing motor 301 operates alternately in forward and reverse rotation during operation. This is achieved by connecting the first upright 203 through the first wheel rod 305, and driving the second upright 409 and the screw 610 to rotate through the second grinding column 406. This causes the pressure plate 606 to move up and down along the screw 610 inside the pressure cylinder 601, thereby pressing the kitchen waste above the pressure cylinder 601 into the interior of the anti-splash structure 5 in stages. This allows the kitchen waste to enter the lower part in a regular manner and be crushed, preventing clogging of the crushing mechanism and improving the smoothness of the device's operation.

[0054] Step 4: The reversing motor 301 operates alternately in forward and reverse rotation during operation, which, in conjunction with the blade 205, crushes the kitchen waste when it rotates forward and stirs it when it rotates reverse, thus making the kitchen waste more evenly and thoroughly crushed.

[0055] Step 5: Through the design of the anti-splash structure 5, in conjunction with the downward pressing operation of the pressure plate 606, when the kitchen waste is pressed into the interior of the anti-splash structure 5, it first contacts the upper side rod 504, thereby pushing the lower end of the upper side rod 504 outward, thus opening the opening of the anti-splash cylinder 501, allowing the kitchen waste to pass through smoothly. When the side rod 504 loses the pressure of the pressure plate 606, the presence of the spring shaft 506 will cause the side rod 504 to retract, and at the same time, the internal cutting blade 508 cuts the kitchen waste. The retracted anti-splash structure 5 can also isolate the upper and lower parts of the anti-splash structure 5, thus preventing the garbage liquid from splashing out.

[0056] Step 6: Through the design of the grinding structure 4, after the grinding column 2 406 is driven to rotate by the upright rod 203, the kitchen waste will be gradually squeezed and gradually conveyed to the crushing structure 2 below through the design of the spiral thread belt 405. Through the design of the grinding structure 4, the kitchen waste is ground and squeezed while being conveyed, which improves the crushing efficiency of the device.

[0057] Step 7: Through the bottom structure 3 and the liquid level inside the fermentation tank 101, the waste liquid will gradually flow into the fermentation tank 101 through the slurry outlet pipe 202. The biogas generated inside the fermentation tank 101 will be produced through the gas pipe 108. When the liquid level inside the fermentation tank 101 is too high, the float plate 310 will float on the liquid surface inside the fermentation tank 101, thereby pushing the lower column 309 upward, thereby causing the gear 2 304 to disengage from the gear 1 303, thus stopping the crushing mechanism from working, avoiding the problem of waste liquid entering the gas pipe 108 due to excessive input of the device, and improving the overflow prevention function of the device.
