Abstract

PURPOSE:To supply the optimum amount of garbage and incinerate it efficiently, by a method wherein the garbage is crushed by a garbage crusher and is sent into a garbage incinerating chamber by a garbage supplying device, thereafter, the garbage is incinerated by projecting microwave against it from a microwave generator. CONSTITUTION:When a power source switch is put ON, a crusher 21 in a garbage crushing unit 3 is operated to take out garbage from the lower opening of a garbage collector 2 and crush it into a proper size. The crushed garbage is transferred by the rotary blade of a rubbish supplying device 22 into a garbage incinerating chamber 4 and is dropped onto a rubbish receiver 7. The amount of crushed rubbish, sent into the rubbish incinerating chamber 4, can be set by the rotating number of the rotary blade. When the crushed garbage is sent into the garbage incinerating chamber 4 by the garbage supplying device 22, a microwave generator 10 is oscillated to generate microwave. The microwave is propagated to the inside of the rubbish incinerating chamber 4 through a wave guide 9 and is projected against the garbage on the rubbish receiver 7. Water, included in the rubbish, absorbs the microwave and generates heat, whereby the garbage is dried. The dried garbage receives the heat of a microwave absorbing and heat generating body 8, whereby the garbage is incinerated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a kitchen waste processing apparatus for incinerating kitchen waste, that is, food waste generated in a kitchen.

Conventional technology Traditionally, kitchen waste has been disposed of by pouring it into a mesh-like kitchen waste storage area installed at the drain of the water tank of the kitchen sink, and leaving the kitchen waste for a while. After natural dehydration, the kitchen waste is taken out and placed in a plastic bag, etc., and then stored in a kitchen waste storage cabinet located near the sink.When garbage is collected about twice a week, the bags are taken out and placed in the communal garbage collection area. They are transported to other locations and disposed of.

Alternatively, you can connect the disposer directly to the drain of the water tank in the sink and crush it every time kitchen waste is generated.
Another option is to flush it directly into the sewer system.

Problems to be Solved by the Invention However, in the former method of these conventional methods, if kitchen waste is left in the storage cabinet for even a while, it will rot and new food will be generated. Every time kitchen waste is generated and an attempt is made to put it away, the stench of rotten kitchen waste fills the kitchen, giving an unpleasant feeling.

In addition, although the latter method has the advantage of being able to dispose of kitchen waste easily, the raw food is discharged directly into the sewer, making it easy for sludge to accumulate in the sewer pipes. In Japan, the Sewerage Law prohibits the discharge of wastewater that exceeds the standard value into the sewer system, so the use of disposers must be avoided even in areas where sewage systems are widespread.

Furthermore, in areas where sewage facilities are not sufficiently developed, disposers cannot be used due to waste disposal laws.

The present invention solves these problems and aims to provide a processing device that incinerates kitchen waste every time it is generated.

Means for Solving the Problems The kitchen waste processing apparatus of the present invention crushes kitchen waste using a kitchen waste crusher, and then sends it to a kitchen waste incineration chamber using a kitchen waste supply device, where it receives microwaves from a microwave generator. It is irradiated and incinerated.

Function: With this configuration, kitchen waste is crushed by the kitchen waste crusher and sent in fixed amounts to the kitchen waste incineration chamber by the kitchen waste supply device. and,
Inside this kitchen waste incineration chamber, the waste is irradiated with microwaves and dried, then ignites and burns, turning into ash in a short period of time.

Embodiment Hereinafter, an embodiment of the kitchen waste processing apparatus of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the structure of this embodiment.

In the figure, reference numeral 1 denotes a metal casing, inside of which there are tapered tapered sequentially from top to bottom. Kitchen waste collector 2
, a kitchen waste crushing section 3, a kitchen waste incineration chamber 4, and an ash receiver 5 are arranged in this order. Reference numeral 6 denotes a lid body, which also serves as a member for preventing microwave leakage from the 2 parts of the garbage collector. 7
is a kitchen waste receptacle, which is arranged below the kitchen waste crushing section 3 within the housing 1, and constitutes the kitchen waste incineration chamber 4. A microwave absorbing heating element 8 is attached to the central portion of the kitchen waste receptacle 7. The microwave absorbing heating element 8 is made of, for example, a sintered body of silicon carbide and has a dish-like shape, and is rotatably supported within the housing 1 by a rotation mechanism (not shown). Reference numeral 9 denotes a waveguide, one end of which is open and connected to the kitchen waste incineration chamber 4 in a microwave manner. Reference numeral 10 denotes a microwave generator, such as a magnetron, which is attached to the other end of the waveguide 9. 11 is an exhaust gas purification device,
Its intake port is connected to the kitchen waste incineration chamber 4.

FIG. 2 is a diagram showing an example of the structure of the kitchen waste crushing section 3. As shown in FIG.

This kitchen waste crushing section 3 includes a crusher 21 and a crushing kitchen waste supply device 2.
2. The crusher 21 consists of at least a pair of gears whose teeth mesh with each other. Further, the kitchen waste supply device 22 is composed of a pair of metal rotary vanes that rotate synchronously, and the rotor vanes have a structure in which a plurality of vanes protrude radially from a rotating body. By selecting the dimensions and number of rotary vanes, the kitchen waste crushing section 3 can be shielded from the kitchen waste incineration chamber 4 by microwaves.

The operation of the apparatus of this embodiment will be explained.

First, when kitchen waste is put into the kitchen waste collector 2 and the lid 6 is closed, a power supply operation section (not shown) becomes operable. As such a safety device, a commonly used device can be used. When a power switch (not shown) is turned on, the crusher 21 of the kitchen waste crusher 3 is activated, and the kitchen waste is taken out from the lower opening of the kitchen waste collector 2 and crushed into a suitable size. The crushed kitchen waste is transferred to the kitchen waste incineration chamber 4 by the rotor of the kitchen waste supply device 22, and falls onto the kitchen waste receiver 7. At this time, the amount of pulverized kitchen waste to be sent to the kitchen waste incineration chamber 4 can be set by the rotation speed of the rotor blade.

The crushed kitchen waste in the kitchen waste incineration chamber 4 is transferred to the kitchen waste supply device 22.
When the microwave is sent in, the microwave generator 10 oscillates and generates microwaves. The microwave propagates into the kitchen waste incineration chamber 4 through the waveguide 9 and is radiated to the kitchen waste on the kitchen waste receiver 7. First, the water contained in this kitchen waste absorbs microwaves, generates heat, evaporates, and dries. When the kitchen waste dries, the microphone ρ-wave absorbing heating element 8 absorbs the microwave and starts generating heat, and its temperature reaches 700-900°C.
It becomes °C. Dry kitchen waste is heated by microwave absorption heating element 8
It burns when it receives heat. The resulting ash is dropped into the ash receiver 5 by inverting the kitchen waste receiver 7, and is discarded when a certain amount has accumulated.

As described above, the kitchen waste supply device 22 can control the amount of kitchen waste supplied to the kitchen waste incineration chamber 4 by selecting the temporary rotational speed of its rotor blades, so that there is always a constant amount of food in the kitchen waste incineration chamber 4. An appropriate amount of pulverized kitchen waste can be supplied, and the kitchen waste can be combusted under optimal conditions.

Gas generated by combustion of kitchen waste is led from the kitchen waste incineration chamber 4 to the exhaust gas purification device 11, where carbon monoxide and harmful nitrogen oxides are removed by a catalyst or the like, and then it is discharged to the outside.

FIG. 3 is a diagram showing another example of the structure of the kitchen waste crushing section 3.

This device is equipped with one rotary vane, and when rotating, the tips of the plurality of vanes are always in contact with the inner wall surface of the kitchen waste passage, so that microwaves do not leak out.

In this device as well, the amount of pulverized kitchen waste to be supplied to the kitchen waste incineration chamber 4 can be adjusted by selecting the rotation speed of the rotary vane.

As described above, according to the kitchen waste processing apparatus of this embodiment, the kitchen waste is first crushed by the kitchen waste crusher 21 and then supplied to the four kitchen waste incineration chambers by the kitchen waste supply device 22, so that the kitchen waste is is always supplied in appropriate amounts. In the kitchen waste incineration chamber 4, the kitchen waste is sent in a pulverized state, so its surface area is large, so when microwaves are irradiated, the moisture contained in it evaporates in a short period of time, increasing efficiency (combustion). Since the kitchen waste is pulverized, the feeding rate to the kitchen waste incineration chamber 4 can be easily controlled, and the amount of incineration can be kept constant.For this reason, the kitchen waste can be collected all at once. Compared to incineration, the amount of exhaust gas generated is constant, so it is not only easy to purify, but also the combustion heat can be used as residual heat, reducing the incineration time. Since it is possible to suppress the sudden temperature rise that occurs when incinerating the gas all at once, the burden on the purification catalyst is lightened (its lifespan is extended, and the amount of catalyst required can be reduced.
Being able to suppress temporary temperature rises also leads to safety and eliminates the risk of fires. Furthermore, unlike the case where a large amount of kitchen waste is combusted at once, there is no need to supply a large amount of air, and the blowing fan may be small.

Effects of the Invention According to the kitchen waste processing apparatus of the present invention, the kitchen waste is first crushed by a crusher and then sent to the kitchen waste incineration chamber, where it is irradiated with microwaves, so that the evaporation of water during microwave irradiation is prevented. It can be accelerated. In addition, since the kitchen waste is sent to the incineration chamber after being crushed, the amount of food waste can always be supplied in an appropriate amount, and it can be burned efficiently.
