Abstract

PURPOSE:To dry and burn garbage and to easily treat garbage by providing both a heating means by microwave and a heat release means of silicon carbide. CONSTITUTION:When garbage A is introduced onto a grate 6, a cover 4 of an introduction port is closed and an electric power source is turned on, microwave generated from a microwave generator 7 is passed through a waveguide 8 and then passed through the heating element 18 of silicon carbide and collides against a filter 20 or the like and reflected. When garbage A is dried with the reflected microwave and water content is removed, heating elements 10, 10a of silicon carbide of the lower part are heated by absorbing microwave and garbage A is burned. In the case when exhaust gas is passed through a secondary combustion chamber 19, it is purified by direct combustion and furthermore purified by a catalytic combustion equipment 22, and discharged to the outside through an exhaust outlet 24. Thereby the blocking of a sewer can be prevented and also atmospheric pollution can be avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a kitchen waste processing machine that processes kitchen waste such as vegetable waste by drying and burning it.

Conventional technology Traditionally, disposers have been widely used as home kitchen waste disposal machines in Europe and the United States, but in Japan, sewage treatment facilities are fully equipped, and the wastewater becomes contaminated and clogged. The reality is that the use of Western-style disposers is prohibited (administrative guidance prohibiting their use has been issued) because they may not be able to process the waste.

Therefore, in ordinary households, kitchen waste such as vegetable scraps is currently stored in a sink accessory, a triangular corner basket at the corner of the sink, or a plastic container in the kitchen.

Problems to be Solved by the Invention If kitchen waste such as vegetable scraps is stored in a sink accessory, a triangular corner basket at the corner of the sink, or a plastic container in the kitchen as described above, then vegetable scraps and other kitchen waste can be stored in the kitchen waste. The bad odor that occurs
They were troubled by dirt and bulk, and also had the disadvantage of spilling sewage when moving kitchen waste such as vegetable scraps.

The present invention eliminates the above-mentioned drawbacks, and its purpose is to eliminate the problem of bad odor, dirt, bulk, etc. caused by kitchen waste such as vegetable scraps, and to remove wastewater from kitchen waste such as vegetable scraps. This is related to a kitchen waste disposal machine that can extremely easily dispose of kitchen waste even if it is spilled.

Means for Solving the Problems The present invention provides a kitchen waste processing machine for drying and burning kitchen waste A such as vegetable scraps, which is equipped with a microwave heating means for drying and burning the kitchen waste A and a silicon carbide heating means. The structure is as follows.

Effect Kitchen waste A such as vegetable scraps is dried and burned using microwave heating means and silicon carbide heating means to process it, resulting in excessive odors, dirt, bulk, etc. produced by kitchen waste such as vegetable scraps. It is extremely easy to process.

A is a hole for air intake, and A is kitchen waste such as vegetable scraps.

Next, the operating state of the garbage processing machine of the present invention constructed as described above will be explained.

First, when the input port cover 4 is opened and the kitchen waste A is placed on the Rosdol 6, the input port cover 4 is closed and the power is turned on, the microwaves generated by the microwave generator 7 pass through the waveguide 8 and are almost directly in front of the It passes through the silicon carbide heating element 18 of the exhaust port 16 located in the air, hits the filter 20, etc., and is reflected. At this time, the silicon carbide heating element 18 is heated by microwaves. The microwaves reflected by the filter 20 and the like hit the upper inner wall 2C of the incinerator body 2 and are further reflected, heating and evaporating the moisture in the kitchen waste A at the lower part and drying the kitchen waste A. In this case, the heating element 10.10a is not heated until the moisture in the kitchen waste A is exhausted.

When the kitchen waste A dries and loses moisture, the silicon carbide heating elements 10 and 10a at the bottom absorb microwaves and heat them, igniting and burning the red-hot and dry kitchen waste A. to ashes.

When the kitchen waste A becomes ash, the ash receiver below the hole 6a of the Rosdol 6 and the small hole 9a of the Rosdol net 9 falls into the box 11.

When the inside of the box 11 becomes full of ashes, the ash receiver takes out the box 11 and throws the ashes outside.

Soot, odor, gas, smoke, etc. in the exhaust gas emitted during drying and combustion of kitchen waste A is purified by direct combustion as it passes through the secondary combustion chamber (heated to 700-800°C) 19, and is further purified in the exhaust pipe 21.
