Abstract

PURPOSE:To dispose of wet garbage easily. CONSTITUTION:Garbage is processed into a fluid state using a stirring process tank 2, and it is stirred with the injection of air in a fermentation process tank 3. After that, it is allowed to be fermented to become dry and a solid, which is, in turn, stored in a storage tank 4. When the tank 4 is full of the solid material, then the solid material is taken out and incinerated. Thereby, the garbage is processed into a solid after fermentation, so that this processing can be automatically performed in a device. Therefore, the garbage has only to be dumped into the device and the device capable of processing the garbage simply is best suited for the disposal of garbage at a general household or a restaurant. In addition, this disposal technique and its device eradicate a source of stinking odor pollution and this device can be installed anywhere.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for processing garbage generated from homes, restaurants, ships, schools, hospital catering facilities, and the like.

0002

2. Description of the Related Art As methods for disposing of food waste, there are two known methods: digging a hole in the ground and burying the waste, and incinerating it.

0003

[Problem to be solved by the invention] However, the method of burying garbage in the soil cannot be used in urban areas where there is no land or on ships, and the buried garbage liquid will seep into the soil and eventually become groundwater. There is a problem of contamination.

Next, the incineration method requires fuel, is costly, and causes smoke and odor problems, making it difficult to adopt in urban areas and requiring safety monitoring during incineration. It is not suitable as a method for disposing of raw garbage.

[0005] An object of the present invention is to provide a method and apparatus for processing garbage that does not take up a lot of space, can be personally installed, and has low processing costs.

[0006]

[Means for Solving the Problems] The structure of the present invention is as follows.

1. The input garbage is processed into a fluidized state while being stirred, and then air is blown into the fluidized processing solution to ferment and dry the waste while stirring, and finally it is transformed into a solid material for processing. How to dispose of raw garbage.

2. The lower half of the main body of the device is divided by a partition wall into an agitation processing tank and a fermentation processing tank with a garbage inlet, and a storage tank with an outlet, and the lower half of the stirring blade is inserted into the agitation processing tank and the fermentation processing tank. The rotation direction and speed of the stirring tank and the fermentation tank are different, and a stirring device whose rotation is controlled by a controller is installed, and an air blowing pipe is placed at the bottom of the fermentation tank. A garbage disposal device comprising an odor trapping port provided above the container, and an odor evacuation device equipped with a blower and a deodorizing filter attached to the odor trapping port.

[0009]

[Operation] Garbage is thrown into the stirring treatment tank from the input port each time. The input garbage is stirred by rotating stirring blades and becomes fluid, and when the stirring tank becomes full, it flows over the partition wall into the fermentation tank and accumulates there. An air blowing pipe is disposed at the bottom of the fermentation treatment tank, and air is mixed into the fluidized processing liquid through this air blowing pipe, and is stirred by a stirring blade to cause fermentation. Normally, the temperature of the treatment liquid rises to 60 to 80°C due to this fermentation, and the odor is sucked out of the machine through the odor-catching port and through the filter. In addition, in order to promote fermentation and drying, a highly water-absorbing substance may be introduced into the fermentation tank as a promoter.

[0010] The treated solution fermented in this way is
Eventually it dries and turns into a small solid. These small solids are moved within the tank by the rotation of the stirring blades, and those that have exceeded the partition wall are collected in the storage tank. When the storage tank is full, the solid matter is taken out, and since this solid matter is in a state where it is easy to burn, it is burned as is.

[0011] The stirring blade is controlled by a timer, for example, by rotating it in the forward direction for 2 hours and in the reverse rotation for 1 hour once a day.
It is not something that should be kept rotating all the time. Since the rotation and blade angles of the stirring tank and the fermentation tank are reversed, the material to be processed moves within each tank by switching the rotation direction to the left or right. Eventually, when it becomes full, the material to be processed is shifted diagonally by the action of the stirring blades, and
This bias is moved in the opposite direction by switching the rotation direction, and fermentation is promoted by repeating this process.

[0012] In the above operation, the processing period for garbage discharged from a standard household (the period during which the storage chamber is full) is about one year. However, the stirring treatment tank is 40 liters,
Fermentation treatment tank 200 liters, storage tank 180 liters.

[0013]

[Embodiment] An embodiment of the present invention will be explained based on the drawings.

Reference numeral 1 designates the main body of the apparatus (processing machine), and the lower half of the main body 1 is connected to the stirring processing tank 2 by partition walls 5 and 5'.
, a fermentation treatment tank 3, and a storage tank 4.

Driven by

Reference numeral 11 denotes a stirring blade having a size such that the shaft 12 and its lower part can fit into the fermentation treatment tank 3, and is driven by a motor 13.

The shafts 9 and 12 have a rectangular cross section to prevent dust from getting stuck therein, and each side has stirring blades 8,
11 is attached, and the twist angles of the stirring blades 8 and 11 are opposite to each other. Further, the rotational speed P on the stirring blade 8 side is faster (larger) than the rotational speed P1 on the stirring blade 11 side. The reason for this is that although a certain degree of speed is required to fluidize food waste, such a speed is not required on the fermentation side.

Reference numeral 14 denotes a stirring blade within the storage tank 4, which is attached to the shaft 12. 15 is an outlet provided above the storage chamber 4, and 16 is a sealing lid.

Reference numeral 17 denotes an air blowing pipe arranged at the bottom of the fermentation processing chamber 3 for uniformity.
has many small holes facing upward, and the air blower 1

Reference numeral 19 denotes an odor trapping port opened above the fermentation treatment tank 3, and an odor exhaust pipe 20, a replaceable deodorizing filter 21, and a suction blower 22 are connected to the odor trapping port 19.

[0021] Reference numeral 23 indicates a drain for removing the drain accumulated in the deodorizing pipe 20, and reference numeral 24 indicates a drain tank.

The operation of the above embodiment will now be explained.

[0023] The raw garbage a is introduced into the stirring treatment tank 2 from the input port 6 each time. This input garbage a is stirred by the rotating stirring blade 8 and becomes a fluid state as shown in FIG. It flows into the processing tank 3 and accumulates there. An air blowing pipe 17 is arranged at the bottom of the fermentation treatment tank 3, and air is mixed into the fluidized processing liquid b from this air blowing pipe 17, and is stirred by the stirring blades 11.
Ferment. Usually, the temperature of treatment liquid b is 60°C due to this fermentation.
The temperature rises to ~80°C, and the odor is emitted from the odor capture port 19 to the odor exhaust pipe 20.
The odor is sucked and discharged outside the machine via a deodorizing filter 21 by a blower 22.

[0024] In this way, the fermented treated liquid b
eventually dries and turns into small solids c as shown in FIG. The small solids c move within the tank 3 by the rotation of the stirring blades 11, and those that exceed the partition wall 5' are stored in the storage tank 4. When the storage tank 4 is full, the solid matter c is taken out from the outlet 15, and since the solid matter c is in a state where it is easy to burn, it is burned as is.

Note that the stirring blades 8 and 11 are rotated for 30 to 60 minutes several times a day under timer control, and are not kept rotating all the time. Since the rotation of the stirring tank 2 side and the fermentation tank 3 side and the angles of the blades 8 and 11 are reversed, the processed materials in the respective tanks 2 and 3 are rotated to the left or right. The material moves in the tank by switching, and when it becomes full, the material to be processed is shifted diagonally by the action of the stirring blades 8 and 11, and this shift is moved in the opposite direction by switching the rotation direction, and by repeating this process, fermentation begins. is promoted.
