[0002] Domestic waste refers to solid waste generated in daily life or in activities that provide services for daily life, as well as solid waste that is deemed as domestic waste by laws and administrative regulations. It mainly includes household waste, market trade and commercial waste, public place waste, street cleaning waste, and waste from enterprises and institutions. Domestic waste can generally be divided into kitchen waste, recyclable waste, toxic and hazardous waste, and other waste. For example, kitchen waste includes leftovers, fruit peels and vegetable leaves generated in daily life; recyclable waste includes waste paper, waste plastics, waste metals, etc.; toxic and hazardous waste includes waste batteries, waste light bulbs, waste thermometers, etc.; other waste includes some waste that is difficult to classify, such as bricks, tiles, ceramics, and slag.

[0003] With the acceleration of urbanization, the amount of domestic waste is increasing. Traditional landfill, incineration and other treatment methods have problems such as environmental pollution and waste of resources. Aerobic degradation technology has received widespread attention as an environmentally friendly and efficient waste treatment technology. When treating domestic waste, the existing waste degradation device usually stirs the waste through a stirring device to promote full contact between the waste and the air, provide sufficient oxygen for aerobic microorganisms, and improve the degradation efficiency of the waste. However, this method requires a lot of energy and increases the energy consumption of the device. Stirring will destroy the temperature environment of the microorganisms in the garbage, and it will take a certain amount of time to restore the temperature to the appropriate range, resulting in a long waste treatment cycle and reduced degradation efficiency. Therefore, it is necessary to improve the existing technology and design an aerobic degradation device for domestic waste to improve the degradation efficiency, shorten the treatment cycle, and simplify the operation process.

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 5As shown, a garbage aerobic degradation device comprises a degradation box 1, a layer of infiltration screen 4 is fixedly provided near the bottom of the degradation box 1, a temperature control ventilation mechanism 3 is provided on the upper side of the infiltration screen 4, a circulation mechanism 2 is provided on the left side of the degradation box 1, a discharge port 5 is provided on the front side of the degradation box 1, and a sealing cover plate 6 is assembled inside the discharge port 5. This design solves the problem that the stirring method used in the prior art to promote garbage degradation requires a lot of energy and increases the energy consumption of the device, and the stirring will destroy the temperature environment of the microorganisms in the garbage, and then it takes a certain amount of time to restore the temperature to a suitable range, resulting in a long garbage treatment cycle and reduced degradation efficiency.

[0027] A layer of sealing rubber pad is pasted around the sealing cover plate 6. The sealing rubber pad can ensure the sealing of the discharge port 5 when it is closed, prevent harmful liquids in the garbage from leaking from the interface, and ensure the cleanliness and safety of the operating environment. The lower side of the sealing cover plate 6 is rotatably connected to the discharge port 5 through a hinge, and a handle is fixed on the front surface of the sealing cover plate 6.

[0028] The circulation mechanism 2 includes a circulation water pipe 22, a nozzle 23, a liquid inlet pipe 24, a water pump 25, a fixing plate 26 and a return pipe 27. The water pump 25 is fixed to the left side of the degradation box 1 through the fixing plate 26. The return pipe 27 is installed on the input end of the water pump 25. The other end of the return pipe 27 is connected to the bottom of the degradation box 1. A mouth-shaped circulation water pipe 22 is arranged on the upper side of the inner wall of the degradation box 1. The output end of the water pump 25 is connected to the circulation water pipe 22 through the liquid inlet pipe 24. The inner side of the annular surface of the circulation water pipe 22 is evenly equipped with multiple groups of nozzles 23. The design can reintroduce the leachate seeping from the garbage into the degradation process through the circulation mechanism 2, which can accelerate the reproduction of aerobic microorganisms and help improve the degradation efficiency.

[0029] A liquid level indicator 21 is installed on the lower left side of the degradation box 1. The liquid level indicator 21 can display the height of the garbage leachate at the bottom of the degradation box 1 in real time, providing intuitive liquid level information for operators, which helps to achieve accurate control and efficient management of the degradation process.

[0030] The temperature control ventilation mechanism 3 includes a blower 32, an electric heater 33, a base plate 34, a ventilation pipe 35 and a ventilation assembly 37. The electric heater 33 is fixed on the right side of the degradation box 1 through the base plate 34. The blower 32 is equipped on the rear side of the electric heater 33. Multiple groups of ventilation assemblies 37 are evenly fixed on the infiltration screen 4. The electric heater 33 is sealed and connected with the ventilation assembly 37 through the ventilation pipe 35. The temperature and air circulation in the degradation box 1 can be accurately controlled by the temperature control ventilation mechanism 3, which avoids the temperature fluctuations that may be caused by the traditional stirring method, and ensures that the microorganisms can continuously and efficiently degrade garbage under a suitable temperature environment. At the same time, the ventilation mechanism can also provide sufficient oxygen to meet the needs of aerobic microorganisms.

[0031] Two groups of temperature sensors 31 are symmetrically installed on the rear side of the degradation box 1, and a temperature controller 36 is arranged on the front side of the electric heater 33. The temperature sensors 31 and the electric heater 33 are connected to the temperature controller 36 through wires. The temperature distribution in the box can be monitored in real time by the two groups of temperature sensors 31, and the data can be transmitted to the temperature controller 36. At the same time, the changing trend of the temperature in the box can be better grasped to ensure the uniformity and stability of the temperature. The electric heater 33 can heat the environment in the degradation box 1 according to the instructions of the temperature controller 36 to maintain a suitable degradation temperature. The temperature controller 36 receives real-time data from the temperature sensor 31 and makes judgments and adjustments according to a preset temperature range. When the temperature in the box is lower than the set value, the controller will instruct the electric heater 33 to start heating; when the temperature reaches or exceeds the set value, the controller will adjust the heating power or turn off the electric heater 33 to avoid excessive temperature from having an adverse effect on microbial activity.

[0032] The ventilation assembly 37 is composed of a wind tube 371 and a wind hood 373. The wind hood 373 is set to a cone structure and is inverted and fixed on the infiltration screen plate 4. The wind tube 371 is connected to the upper side of the wind hood 373. The surfaces of the wind tube 371 and the wind hood 373 are provided with multiple groups of through holes 372. The design of the through holes 372 further increases the contact area between air and garbage, improves the ventilation effect, and enables the leachate in the garbage to flow into the wind hood 373 through the through holes 372 and be introduced into the bottom of the degradation box 1. The ventilation assembly 37 can be provided to transport air to the inside of the garbage, which can effectively promote the air circulation and oxygen supply inside the garbage aerobic degradation device. By providing sufficient oxygen and a uniform ventilation environment, it helps to accelerate the degradation process of garbage, improve the degradation efficiency, and maintain the activity of the microbial community.

[0033] The working principle of the aerobic garbage degradation device is as follows: in actual use, the domestic garbage is first piled into the degradation box 1, so that the garbage height is slightly lower than the height of the circulating water pipe 22, and then the heating temperature is preset through the temperature controller 36, and the electric heater 33 and the blower 32 are started. The electric heater 33 heats the wind blown by the blower 32, and then the hot wind is transported to the wind tube 371 and the wind cover 373 through the ventilation pipe 35, and then transported to the garbage through the through hole 372 thereon, promoting the air circulation and oxygen supply inside the garbage, providing sufficient oxygen for the degradation of aerobic microorganisms, and facilitating the degradation of garbage. When the temperature in the box is lower than the set value, the controller will instruct the electric heater to start heating; when the temperature reaches or exceeds the set value, the controller will adjust the heating power or turn off the electric heater to avoid the adverse effect of excessive temperature on microbial activity. At the same time, the leachate at the bottom of the degradation box 1 can be pumped out by the water pump 25 and transported to the circulating water pipe 22, and then evenly sprayed into the garbage from the upper side through the nozzle 23. Since the leachate contains a large amount of aerobic microorganisms, the reproduction of aerobic microorganisms can be accelerated, which helps to improve the degradation efficiency.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
