Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a household kitchen waste disposal device that processes and composts kitchen waste mainly discharged from the kitchen.

BACKGROUND OF THE INVENTION As shown in FIG. 2, a kitchen waste composting device conventionally used at home has an input port 23 on the top of a substantially cylindrical case 22 with an opening 21 on the bottom. Input port 23 to 1
124, it is installed by digging slightly into the ground, and kitchen waste is thrown into the case 22 together with microorganisms.
The idea is to create compost through anaerobic decomposition and fermentation.

Problems to be solved by the invention However, the above-mentioned installation requires ground, microorganisms are required because it uses anaerobic fermentation, and the product rots extremely inside and produces a bad odor. or
It took several months to turn into compost, so it was a rudimentary composting device, and it was difficult to use to actively compost kitchen waste.

The present invention solves these conventional drawbacks, and by providing a configuration suitable for the aerobic fermentation kitchen waste composting procedure, it can be installed even in areas without ground, does not require special microorganisms, and does not generate bad odors. To provide a household kitchen waste processor capable of reliably composting kitchen waste in a short period of time.

Means for Solving the Problem In order to solve this problem, the household garbage disposal device of the present invention has a substantially cylindrical shape with a partition wall inside and multiple chambers, and is covered with a heat insulating material. The top side of the outer case is provided with an inlet for the material to be processed and an air outlet, and the side of the case is provided with an outlet for the material to be processed and an air suction port. A pipe-shaped rotating support is provided through the wall, driven by a motor, and hollow on the inside and having appropriate ventilation holes in the wall surface. A spiral-shaped cut-back board that gets higher? ! Install several pieces, bottom tJ
The partition wall is provided with a communication port that can be opened and closed at any time, and the other partition walls are provided with a large number of holes that gradually become smaller in size than the upper part.

With this structure, the kitchen waste dropped from the input port falls onto the partition wall, is turned back by the cutting board and is sieved one by one, and the kitchen waste that remains on the partition wall soil undergoes initial fermentation through aerobic fermentation, and is further sieved and transferred to the bottom stage. It reaches the partition wall, where it is cut back with a cut board to continue the main fermentation, and when it reaches a certain amount, it is dropped to the bottom through the communication port of the partition wall, where it is further cut back with a cut board and stored for aging. and composted.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, reference numeral 1 denotes an outer case, and a heat insulating material 2 is provided on the inner surface of the outer case 1.

Reference numeral 3 denotes partition walls provided in the exterior case 1 at intervals of a plurality of stages, and 4 is a partition wall at the lowest stage.

Furthermore, a kitchen waste inlet 5 and an air exhaust tube 6 are provided on the upper surface of the exterior case 1. 7 is a compost outlet provided on the lower side wall of the outer case 1; 8 is an air intake port provided in the lid of the compost removal lower; 10 is a rotary pipe extending vertically through the partition walls 3 and 4. The lower end of the column is rotatably held by a rotary support part 9 provided on the bottom of the outer case 1, and the upper end is connected to a drive motor 11 provided on the top of the outer case 1. 12 is a pipe-shaped rotating support 1
This is a ventilation hole appropriately provided on the side wall of 0. 13 is a hole bored in the partition 13, the size of which gradually decreases from top to bottom. 14 is a cut-back board, and the lower end of each is a partition li! 3.4 and is formed in a spiral shape close to the bottom surface of the exterior case 1 and has a higher upper end, and the cut-back plate 14
The base is fixed to the rotating support 10 and rotates together with the rotating support 13, and the kitchen waste accumulated on the partition walls 3, 4 and the bottom is sequentially turned over and brought into contact with the air. Reference numeral 15 denotes a communication port provided in the lowermost partition wall 4, and an opening/closing shutter 16 that is operated when moving kitchen waste from the F chamber to the lower chamber is attached.

In the above configuration, to explain its operation, the kitchen waste dropped from the input port 5 falls on the partition wall 3, and the cut-back plate 1
4, particles finer than the holes 13 fall onto the lower partition wall 3, are sequentially sieved, and reach the lowermost partition wall 4. On the other hand, each partition wall 3''-
While being cut back, the kitchen waste is fermented and decomposed by bacteria in the air through so-called aerobic fermentation, and when it becomes smaller than the hole 13, it falls to the lower stage, where it is similarly sieved and reaches the bottom partition wall 4. . The fallen kitchen waste is cut back by a cut-back plate 14 that moves with the rotation of the rotating support 10, and fermentation continues.

In the process up to this point, the kitchen waste is sieved, initial fermentation, and main fermentation by cutting. Furthermore, the kitchen waste that has mainly fermented on the partition wall 4 can be removed from the communication port 1 on the partition wall 4 by operating the opening/closing shutter 16 when it is collected in quantity.
5 and falls to the bottom side. Note that the kitchen waste is dropped by being scraped out through the communication port 15 by rotating the cut-back plate 14.

The fallen kitchen waste is further cut back by the cut-back board 14 and aged and stored to become compost, and the finished compost is appropriately taken out from the take-out lower and used for gardening, etc.

The air that maintains aerobic fermentation enters through the air suction port 8 and is heated by the fermentation heat released during fermentation of kitchen waste (50~
60℃), from the ventilation hole 12 of the lower chamber to the rotating column 1
The air rises inside the room, flows into the room from the vent 12 in the upper room, and is discharged from the air exhaust tube 6, creating a flow that further promotes aerobic fermentation.

In addition, 1. :r Since the heating material 2 has the ability to effectively retain fermentation heat, there is no need to reduce the amount of air in order to limit heat loss due to the heat carried out by the exhaust air compared to the case without it. , since more air can flow in, it has the effect of further promoting aerobic fermentation.

Effects of the Invention As described above, the household kitchen waste processor of the present invention is suitable for the aerobic composting procedure of kitchen waste, has a simple configuration, can be installed even in a place without ground, and has special microorganisms. It also eliminates the need for waste, does not generate bad odors, and can reliably compost kitchen waste in a short period of time.
