[0020] Please see Figures 1 to 4 The present invention provides an air-source heat pump organic waste treatment system, including a fermentation pretreatment component, a bucket crushing component and a fermentation component, wherein the fermentation pretreatment component and the bucket crushing component are both connected to the fermentation component;

[0021] The fermentation assembly includes a base 1, a screw conveyor 2, a feed inlet 3, a fermentation chamber 4, multiple discharge blades 5, multiple central blades 6, multiple circulating discharge blades 7, a fermentation chamber top cover 8, a mixing reducer 9, a mixer 10, a screw conveyor discharge outlet 18, a screw conveyor reducer 12, multiple mixer single-layer sieve blades 13, a circulating discharge gate 14, multiple sieves 15, multiple sieve fixing feet 16, an exhaust pipe 17, a discharge outlet 18, a heating unit, and a control cabinet 23. The fermentation chamber 4 is located above the base 1. One end of the screw conveyor 2 is connected to the fermentation chamber 4, and the other end of the screw conveyor 2 is connected to the fermentation chamber 4 through the screw conveyor discharge outlet 18.

Multiple sieve plates 15 are respectively mounted inside the fermentation chamber 4 through corresponding sieve plate fixing feet 16. The exhaust pipe 17 is connected to the fermentation chamber top cover 8. The discharge port 18 is mounted on the fermentation chamber 4. The feed inlet 3 is connected to the fermentation pretreatment component. The heating unit is mounted on the base 1 and the fermentation chamber 4.

[0022] The heating unit includes a hot oil generator 19, a heat-conducting oil pipe 20, an industrial hot air blower 21, and a hot air duct 22. The hot oil generator 19 is mounted on the base 1 and located on one side of the fermentation chamber 4. The heat-conducting oil pipe 20 is connected to the hot oil generator 19 and is distributed on the inner bottom wall of the fermentation chamber 4. The industrial hot air blower 21 is mounted above the base 1 and located on one side of the control cabinet 23. The hot air duct 22 is connected to the industrial hot air blower 21 and is distributed on the inner wall of the fermentation chamber 4.

[0023] In this embodiment, the fermentation pretreatment component crushes and mixes various organic wastes, then conveys them to the fermentation chamber 4 through the feed inlet 3. The agitator 10, driven by the mixing reducer 9, performs the mixing and fermentation. Simultaneously, the hanging bucket crushing component crushes and conveys the perishable kitchen waste to the fermentation chamber 4. The mixture is then conveyed upwards by the screw conveyor 2 and returns to the fermentation chamber 4 from the screw conveyor outlet 18 for fermentation. The mixture is circulated and stirred for fermentation. After fermentation, the oil heater 19 heats the oil, maintaining the temperature below 250 degrees Celsius, and then conveys it to the inner bottom wall of the fermentation chamber 4 through the heat-conducting oil pipe 20, allowing the organic waste to be processed from below. The waste is heated, and the industrial hot air blower 21 is started, which delivers the hot air to the fermentation chamber 4 through the hot air duct 22 for hot air drying. The dried water vapor is discharged from the exhaust pipe 17 and finally from the discharge port 18. When the moisture content of the organic waste is controlled at 30%, the entire straw-to-organic-fertilizer production process is completed. The base 1 supports the fermentation chamber 4, and the fermentation chamber top cover 8 covers the top of the fermentation chamber 4 to prevent dust and foreign objects from entering. At the same time, it supports the mixing reducer 9. The mixing reducer 9 is started, which drives the agitator 10 to run and mix the organic waste.
