[0034] A polyurethane thermal insulation layer is arranged outside the composting chamber 103. The polyurethane thermal insulation layer has good thermal insulation performance, can reduce the heat loss during the composting process, and keep the temperature in the composting chamber 103 stable. A stable temperature environment is conducive to the growth and activity of microorganisms, improves the composting efficiency and quality, and also reduces energy consumption.

[0035] Working principle:

[0036] The waste wooden furniture enters the crushing chamber 101 of the housing 1 from the feed hopper 2. First, it passes through the primary crushing mechanism. The first driving motor 22 drives the first rotating shaft 18 and the first crushing roller 19 to rotate. The first teeth 20 perform a preliminary rough crushing on the furniture, disassembling the larger pieces of furniture into smaller sizes for subsequent further processing. Then the material falls into the secondary crushing mechanism. The second driving motor 27 drives the second rotating shaft 23 and the second crushing roller 24 to rotate. The second teeth 25 perform a finer crushing on the material to ensure that the particle size of the material meets the requirements for composting. The crushed material is screened by the filter screen 3, and the qualified material enters the storage chamber 102 for temporary storage. When composting is required, the on-off valve 5 on the material guiding pipe 4 is opened, and the material enters the composting chamber 103. During the composting process, the temperature sensor 6, humidity sensor 7, oxygen concentration sensor 8, and pH value sensor 9 continuously monitor the various parameters in the composting chamber 103 and transmit the data to the control display screen 33. The operator can, based on these parameters, control the solenoid valves 14 on the nitrogenous organic additive pipe 10, active microorganism inoculation pipe 11, compost physical and chemical adjustment material input pipe 12, and ventilation pipe 13 through the control display screen 33 to add the corresponding materials and gases into the composting chamber 103. The nitrogenous organic additive pipe 10 inputs livestock manure, urea, etc., providing a key nitrogen source for the reproduction of microorganisms. The microorganisms utilize the nitrogen to rapidly proliferate and decompose the organic matter of the waste wooden furniture, accelerating the composting and ripening process. The active microorganism inoculation pipe 11 inputs white rot fungus agent and Bacillus subtilis agent. The lignin-degrading enzymes secreted by the white rot fungus target and break through the lignin barrier. Bacillus subtilis helps the conversion of organic matter with various extracellular enzymes and simultaneously inhibits harmful pathogens to maintain the ecological stability of the compost. The compost physical and chemical adjustment material input pipe 12 inputs peat soil, perlite, and lime. The peat soil and perlite improve the air permeability and water retention of the material, preventing the compost from caking. The lime precisely neutralizes acidic substances to maintain an appropriate pH value and create good living conditions for microorganisms. The ventilation pipe 13 continuously introduces air to ensure aerobic respiration of the microorganisms. Occasionally, purified carbon dioxide or nitrogen is introduced according to the composting situation to fine-tune the gas atmosphere and promote the balanced progress of composting. At the same time, the electric heating sheet 15 can adjust the temperature in the composting chamber 103. The turning mechanism drives the rotating shaft 34 and the turning blades 35 to rotate through the rotating motor 36 to turn the material. The spraying mechanism sprays water mist into the composting chamber 103 through the atomizing nozzle 37 and the water valve 39 to adjust the humidity. When the composting is completed, the discharge valve 17 on the discharge pipe 16 is opened, and the organic fertilizer is discharged from the discharge pipe 16.

[0037] This device avoids the environmental pollution caused by traditional landfill and incineration treatment methods, realizes the resource recycling of waste wooden furniture, and converts it into organic fertilizer.
