PURPOSE:To lightly convert a wet refuse into an organic fertilizer by forming a net bottom near the bottom of a tank, dividing the tank into the upper and lower two chambers, providing a rotating blade and a stirring mechanism in the upper chamber and a blower in the lower chamber. CONSTITUTION:A lid plate 6 is opened and a wet refuse containing an aerobic bacterium mixed therein is charged into an upper chamber 10 of a tank 1. The lid plate 6 is then closed. The blade tip 30 on the outer peripheral part of a screw 3 supported by supporting rods 32 radially fixed on a rotating shaft 31 is then rotated to cut the wet refuse, which is simultaneously mixed with the aerobic bacterium. On the other hand, a blower 4 in the bottom of the lower chamber 11 divided with a net bottom 2 provided near the bottom of the tank 1 is operated. Air heated by a heater is fed into the lower chamber 11, passed through the net bottom 2 and fed into the upper chamber 10 to decompose and ferment the wet refuse. The resultant decomposed and fermented wet refuse is then discharged from a vent port 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic compost production tank for efficiently decomposing organic matter to be treated such as garbage mixed with aerobic microorganisms to obtain organic compost.

[0002]

2. Description of the Related Art In the present invention, there are plant residues such as vegetables and fruits, small cut residues of animals such as fish and shellfish and poultry, wastes of okara and the like produced in the process of manufacturing processed foods, leftover rice and shavings of timber. Sawdust, chips, and organic residue such as animal and poultry manure are collectively referred to as raw garbage. Conventionally, small incinerators are mainly used for treating these raw garbage in-house without sending them to the garbage collection. Has come.

Recently, among environmental problems, the problem of garbage disposal, which is familiar to the public, has been greatly highlighted. At the core of this problem is the recycling of products, but when we look at foods among products, the idea and technology to recycle and effectively utilize raw garbage in each household is still unclear. Not established, raw garbage is often only incinerated in household incinerators, and most of it is sent to garbage collection and ends up. The processing capacity has already reached its limit.

[0004]

However, when garbage is treated in each household, it is inevitable to accelerate the deterioration of the environment due to air pollution when the garbage is incinerated using an incinerator. In addition, most of the foodstuffs, including raw garbage, are the rest of the food, so it is absolutely unavoidable to simply incinerate it without using it effectively.

In view of the above-mentioned problems, the present inventor may reuse raw garbage for cultivation of flowers and foliage plants, cultivation of home gardens, etc., if it is possible to transform it into organic compost at home. Yes, it is possible to establish a social system to recycle it to the agricultural field as it goes, and it is thought that it can contribute to the problem of waste disposal by using this, and decomposes raw garbage by using aerobic bacteria. We obtained the knowledge that it can be changed to organic compost. Therefore, an object of the present invention is to provide a simple device that can easily convert raw garbage into organic compost in each home.

[0006]

In order to achieve the above object, the present invention forms a net bottom near the bottom of a tank to form the tank into two chambers, an upper chamber and a lower chamber, and a rotary blade and a stirring mechanism in the upper chamber. Installed, the rotary blade and stirring mechanism are driven by a motor, a blower for blowing air into the lower chamber is installed at an arbitrary location in the tank, and an exhaust port is opened in the upper chamber to contain a deodorant. An organic compost manufacturing tank was provided by attaching a container and providing a lid for the entry and exit of organic matter to be treated such as raw garbage at any location on the tank.

[0007]

To use the present invention, the above-mentioned plant residues such as vegetables and fruits, small cut residues of animals such as fish and shellfish and poultry, waste of okara, etc. generated in the process of manufacturing processed foods, leftover rice, timber Sawdust and chips that are shavings of, and further dropping manure of animal and poultry etc. into the upper chamber of the tank by opening the lid of the entrance, mixing a little aerobic bacteria (bio) that can decompose raw garbage, Close the entrance lid. Next, when the power of this machine is turned on, the motor rotates, the rotary blade cuts the garbage into small pieces, the stirring mechanism stirs and mixes the garbage and aerobic bacteria, and the blower operates to blow air into the lower chamber. The air blown into the lower chamber enters the upper chamber through the net bottom, passes through the mixture of organic substances to be treated such as garbage and aerobic bacteria, supplies oxygen to these, and the microorganisms grow. The environment is adjusted and the air is exhausted outside the tank through the exhaust port equipped with a deodorizer.

When air (oxygen) is blown into a mixture of raw garbage and aerobic bacteria, microorganisms promote the decomposition and fermentation of raw garbage, and after a required number of days, it is converted into organic compost. .. The volume of organic compost is about 20 to 2.5% less than the volume of original garbage, and aerobic bacteria grow during this period, so garbage can be added to this tank one after another. , It is possible to react repeatedly until the tank is full. Depending on the type of organic matter to be treated, some odor may be generated during this decomposition and fermentation process, but at this time the deodorant with a built-in deodorant finishes deodorizing it, so the exhaust from the exhaust port It is virtually odorless. Further, water and the like generated from raw garbage is dropped and stored from the net bottom into the lower chamber, so it may be removed if necessary. Since the action of microorganisms that promote the decomposition and fermentation of raw garbage is maximum when a large amount of oxygen and an appropriate temperature are given, the air blown into the lower chamber is used as warm air and any warm air that can generate the warm air can be generated. It is also preferable to provide a heating means.

EXAMPLE An example of the present invention will be described below, but the present invention is not limited to this example.

FIG. 1 is a partially cutaway perspective view of the first embodiment, FIG. 2 is a partial sectional view of an upper chamber 10 of this embodiment, and FIG. 3 is a partial sectional view of a lower chamber 11 of this embodiment. Yes, FIG. 4 is a sectional view of the deodorizer 50 of the present embodiment.

A net bottom 2 is provided near the bottom of a substantially cylindrical tank 1 made of stainless steel, and the inside of the tank 1 is provided with an upper chamber 10 and a lower chamber 1.
1, and the rotary shaft 31 is passed through the center of the upper chamber 10
The rotary shaft 31 is rotatably attached to a motor 33 fixed to the upper part of the upper chamber 10 via a speed reducer 34, and a blade 32 is radially fixed to a three-fold symmetrical position of the rotary shaft 31 and has a cutting edge 30 on the outside. Spiral 3 (also serves as a rotary blade and stirring means)
Was attached so that the blade edge 30 was close to the tank inner wall surface 13 of the upper chamber 10, the exhaust port 5 was opened in the top plate 12 of the upper chamber 10, and a deodorant such as activated carbon was put inside the exhaust port 5. The deodorizer 50 is attached, and the upper chamber 10 is opened through the opening 51.
The top plate 12 is ventilated inside, and an opening 61 is opened for charging raw garbage, and a lid plate 6 with a handle 60 is provided at the opening 61 so as to be openable and closable. Exit 7
1 is opened, a lid plate 7 with a handle 70 is openably and closably attached to the outlet 71, a blower 4 is fixed to a bottom plate 15 of the tank 1, and a pipe 41 is attached to the bottom plate 15 from the blower 4 via a heating device 40. The blower opening 14 is connected to the opened blower opening 14
The tray 9 is provided in the lower chamber 11 so that it can be freely taken in and out in the lateral direction so that it does not overlap, and leg portions 8 with casters are attached to the bottom plate 15 at three-fold symmetrical positions. Reference numeral 81 is a handle of the tank 1.

This embodiment is an organic compost manufacturing tank of a type that is mainly configured for home use and can be stored under a sink or the like. Small pieces of food such as poultry and poultry, leftover food, etc. are put into the upper chamber 10 of the tank 1 by opening the lid plate 6 at the entrance, and a very general aerobic bacterium capable of decomposing these garbage (bio ) Is mixed in a little, and the lid plate 6 at the inlet is closed. Next, when the power of the machine is turned on, the motor 33 rotates, the spiral 33 rotates to stir and mix the raw dust and aerobic bacteria, and the blade edge 30 at the outer edge of the spiral 33 cuts the raw dust into small pieces. The blower 4 at the bottom of the chamber 11 operates to send air to the pipe 41, but the air is blown into the lower chamber 11 after being appropriately warmed by the heating device 40. The warm air blown into the lower chamber 11 enters the upper chamber 10 through the net bottom 2 and passes through the mixture of garbage and aerobic bacteria to supply them with temperature and abundant oxygen. The odor is raised by the deodorizer 52 in the deodorizer 50 through the passage 51 while preparing the environment for the growth of microorganisms, and is discharged to the outside of the tank 1 through the exhaust port 5. In this series of processes, when warm air (oxygen) is blown into the mixture of garbage and aerobic bacteria, the decomposition and fermentation of garbage is promoted by the action of microorganisms, and it depends on the type of organic matter to be treated. But,
Example: 3 days for vegetables, 5 days for citrus peels (known to decompose from the back of the skin), 3-5 days for wild grasses, 20 days for meats with relatively low fat content, Bone can be converted into organic compost after the required number of days on the 23rd. When treated in this way, the volume of organic compost is 20 to 2.5% smaller than the volume of raw garbage, though aerobic bacteria continue to grow, although it depends on the type of organic compost. Therefore, garbage can be added to the tank 1 one after another, and the reaction can be repeated until the tank 1 is full. Also, during this treatment process, water etc. will come out from the garbage,
Since water is drip-stored from the net bottom 2 into the lower chamber 11, the tray 9 may be pulled out and removed in front of the water when it has accumulated to some extent. Further, the generated organic compost is scraped out from the outlet 71 by opening the lid plate 7 below the upper chamber 10.

In the present embodiment, the warm air from the blower 4 is blown into the lower chamber 11 through the blower port 14 and is sent from the net bottom 2 to the upper chamber 10. The warm air is decomposed and fermented of raw garbage. This is because the environment of the microorganisms that assist the heating is adjusted, so that the heating device 40 does not necessarily have to be operated when the temperature is high or in a rural area. Further, the upper chamber 10 may be configured not to be jetted from the net bottom 2 but to be ejected from a hollow rotary shaft 31 through a radial hollow support rod 32 and a small hole opened in the support rod 32. (In this case, lower chamber 1
1 can be thought of as a container for storing the water generated from raw garbage). In the present embodiment, the net bottom 2 is for dropping the water discharged from the garbage into the lower chamber 11 and for sending warm air to the upper chamber 10, so that the net bottom 2 has many arbitrary plates. May be opened, and in the present invention, this is also defined as a net bottom.

Next, FIG. 5 is an internal plan view of the upper chamber 10 of the second embodiment. Unlike the agitating mechanism of the spiral 3 having the cutting edge 30 on the outside of the first embodiment, the same plane 3 is shown. It is a stirring mechanism that is formed in a rotationally symmetrical manner and has a scoop 35 having a cutting edge 30 on the outer edge formed in multiple stages on a rotary shaft 31. The charged organic matter is pressed by the cutting edge 30 and the inner wall surface of the upper chamber 10. It is configured such that it is crushed by a scoop and agitated by the scoop 35.

Next, FIG. 6 is a partial sectional view of the lower chamber 11 of the third embodiment. A motor 33 for driving the rotating shaft 31 is provided under the top plate 12 of the upper chamber 10 of the first embodiment. And reducer 3
4 is disliked, and another casing is formed further below the bottom of the lower chamber 11, and the blower 4, the motor 33, and the speed reducer 34 are arranged in the casing. A blower opening 42 for the blower 4 and a through hole 91 for draining water from the garbage are opened. Doorway 91
A tank 90 for storing water is installed on the lower side of the tank 9, and the lid plate 16 formed on the wall surface of the tank 1 at this portion is opened / closed to open the tank 9
