Embodiment 1

[0018] A domestic automatic fruit and vegetable waste composting device, the device is equipped with a seven-character switch 1, a motor 2, a pull-out main composting chamber 3, an odor processing unit 6, and a fermentation liquid storage chamber 4;

[0019] The feeding port 11 of the seven-character feeder 1 is located at the top of the device, and one end of the auger 12 in the seven-character feeder 1 is connected with the shaft pulley 13, and the shaft pulley 13 is connected with the motor 2 through the belt 5, and the The other end of the auger 12 is provided with a cross blade 14, and the discharge port of the seven-character channel 1 is provided with a baffle plate 15 with a porous structure, and the discharge port of the seven-character channel 1 is connected with the inlet of the main composting chamber 3. Feed mouth is connected, and the top of described main composting chamber 3 is provided with odor treatment unit 6, is provided with reticular activated carbon in d...

Embodiment 2

[0021] A composting method using the device described in Example 1, the composting method is as follows: turn on the motor 2, put fruit and vegetable waste and fermentation bacteria into the seven-character channel 1, and the motor 2 drives the auger through the belt 5 and the shaft pulley 13 12. Convey and stir the fruit and vegetable waste, crush the fruit and vegetable waste when it reaches the cross blade 14, and then control the degree of crushing of the fruit and vegetable waste through the aperture of the blocking plate 15, and the crushed fruit and vegetable waste is driven by the rotating force Enter the main composting chamber 3 under the dual action of extrusion force and composting fermentation, the composting period is 12d, the fermented liquid that can be used as a natural detergent during the fermentation process enters the fermented liquid storage chamber under the action of gravity through the liquid outlet hole 4, and then recovered from the outlet of the ferm...

Abstract

The invention relates to a household automatic fruit and vegetable waste composting device, and belongs to the technical field of garbage disposal. A straight tee joint, a motor, a main composting chamber, an odor treatment unit and a fermented liquid storage chamber are arranged in the device, a feeding port of the straight tee joint is positioned at the top of the device, one end of an auger inthe straight tee joint is connected with an axle belt pulley, the axle belt pulley is connected with the motor through a belt, a cross blade is arranged at the other end of the auger, a discharging port of the straight tee joint is provided with a porous baffle plate and connected with a feeding port of the main composting chamber, the odor treatment unit is arranged at the top of the main composting chamber, a plurality of vent holes are formed in the bottom of the odor treatment unit, a plurality of liquid outlet holes are formed in the bottom of the main composting chamber, and the fermented liquid storage chamber is connected with the bottom of the main composting chamber. Fruit and vegetable wastes composted by the device can be degraded to 70-80% of the original and can be reduced.

Description

technical field [0001] The invention relates to a domestic automatic fruit and vegetable waste composting device, which belongs to the technical field of garbage treatment. Background technique [0002] At present, kitchen waste is a kind of solid waste, and its treatment methods mainly include incineration, landfill and composting. Due to the high biodegradability and water content of kitchen waste, it is not suitable to use incineration for its low calorific value. If it is disposed of in landfill, the leachate will have a lot of leachate, which is difficult to recover and will cause secondary pollution. Instead, it should be treated with compost Its fermented liquid can be used as natural detergent again and its fermented residue can be used as organic fertilizer. Therefore, composting is a more suitable treatment method. However, kitchen waste is widely scattered and not easy to collect centrally, so it is more reasonable to compost on a household basis. Currently, the...
