Description

Apparatus for disposing food garbage

The present invention relates to an apparatus for treating household waste, and more particularly, to dry and dehydrate household waste in a short time so that it can be used as a livestock feed or organic fertilizer, and to prevent pollutants from being discharged to the environment during processing. It relates to a household waste treatment apparatus that can prevent the.

In general, when household waste is put in a garbage bag without being drained, odors and pollutants emitted from the garbage often appear as the main culprit of environmental pollution. In order to solve the above problems, recently, there has been an attempt to process food waste containing water by drying it using combustion heat to reduce the amount of residues in a minimized state and to put it in a pay-per-use bag.

The food waste processor registration utility model registration No. 0137798 will be described in detail with reference to the accompanying drawings.

1 is an overall perspective view of a conventional food waste, Figure 2 is a cross-sectional view showing the configuration of a conventional food waste disposal. As shown in these figures, the larger and smaller ones of the residues A in the separating cylinder 5 composed of the upper mesh 5a and the horizontal mesh 5b are respectively the upper mesh 5a and the horizontal mesh 5b. Hangs on and separates. The water mixed with the waste water is drained through the drain hole 3 provided in the bottom portion of the horizontal mesh 5b. And, only the debris (A) having good dehydration state is caught on the meshes (5a, 5b), but the residue (A) attached to the upper mesh (5a) is relatively large, so it is removed manually and small caught on the horizontal mesh (5b). The residue A of the form is transferred to the grinding rollers 7a and 7b by the conveyor 6 connected to the grinding rollers 7a and 7b operated by the motor M1 to the separating cylinder 5, and then the hopper 4 Is put into. Food waste injected into the interior through the hopper 4 is turned right on the upper heating plate 8a, left on the middle heating plate 8b and evenly stirred by the wings 9 of the wing body that again turns right on the lower heating plate 8c. Heated and dried by the combustion heat of the honors Ba and Bb, it is discharged through the outlet 2 in powder form. And combustion gas and water vapor generated during drying is discharged through the chimney (1).

However, the above-described food waste disposal device includes various problems described below.

First, there is a hassle that the food debris hanging on the upper mesh mentioned above must be removed manually by hand.

Second, the combustion gas and pollutants generated during drying are discharged to the outside without a purification process, which may cause a bad smell.

Third, the burner must be used to heat a fairly large portion of the heating plate, and there are significant structural inefficiencies.

Another conventional attempt to treat food waste has been attempted to compost and organic feed by adding fermentation aids to food waste directly to ferment.

Conventional food waste disposal system using the fermentation aid described above will be described in detail with reference to the accompanying patent registration No. 0151299.

Hereinafter will be described the operation and effect of the household waste treatment apparatus according to the present invention.

First, the user operates the household waste treatment apparatus described above, and puts household garbage in the hopper 110 to be loaded. The household waste accumulated in the hopper 110 is guided by the guide mountain of the transfer screw 113 as the transfer screw 113 rotates and is transferred to the connection duct 114 at the edge portion of the loading portion. Thus, the waste is sent to the upper region of the grinding chamber 130 through the connection duct 114. Garbage falling from the top of the grinding chamber 130 is crushed to the size of the concave groove 133 or less while passing through the mating contact surface of the grinding gears (131a, 131b) rotated in mutually in the grinding chamber 130. To the bottom of 130). The crushed garbage is transferred to the discharge port side of the grinding chamber 130 by the pressure screw (132a, 132b), and is sent to the receiving chamber 140.

At this time, the high frequency generator 142 is operated to radiate high frequency into the receiving chamber 140, the waste contained in the receiving chamber 140 is evaporated by the high frequency of its contained moisture and contaminants are solidified. The solidified waste is sandwiched between the solidifying holes 147 of the rotating plate 141, and as the rotating plate 141 rotates, the solidified waste is solidified into the solidifying hole 147 by the discharge plate 148. Garbage is pushed to the bottom to fall to the bottom of the rotating plate (141). Thus, the solidified waste of a thin film form is collected and collected in the collecting unit 149 provided below the rotating plate 141.

The vapor gas evaporated from the waste passes through the passage duct 160 above the receiving chamber 140 to neutralize the smell and the gas, and the ozone generator 161 releases the ozone to the passage duct 160 so that the ozone vapors. By adding to the gas, the vapor gas is purified. Typically, ozone (O ₃ ), which is used as a disinfectant and disinfectant to sterilize water and air by oxidizing power, is also used as a bleach and as an air purifier to purify exhaust gas as described above. In general, the exhaust gas is mainly composed of hydrogen sulfide methane (CH ₃ -SH), and hydrogen sulfide methane (CH ₃ -SH) is a main cause of environmental pollution as a substance causing odor. Therefore, when ozone (O ₃ ) is added to the exhaust gas, methane sulfate (CH ₃ -SO ₃ H) is formed by an oxidation reaction in which hydrogen sulfide methane (CH ₃ -SH) chemically bonds with ozone (O ₃ ). Is generated. Thus, toxic hydrogen sulfide methane (CH ₃ -SH) in the exhaust gas is naturally removed and odorless methane sulfate (CH ₃ -SO ₃ H) is produced. Table 1 shows the above chemical reactions.

TABLE 1

CH ₃ -SH + O _3- > CH ₃ -SO ₃ H

Purified vapor gas containing odorless methane sulfate (CH ₃ -SO ₃ H) is discharged to the outside through the steam discharge duct (165).

As a result, dehydration is dried, has a uniform shape, and a non-solid solid is formed, so that it can be used as an organic fertilizer, and can be produced and used immediately due to short drying and dehydration time, and separately stores or collects food waste discharged from the home. It has the advantage that it can be processed as soon as it is created without the need to do it. In addition, the water vapor generated during the dehydration drying process is discharged to the outside, and most of the pollutants from the waste are removed during the drying process, but the excess contaminants are removed through the filtering means, and only the purified air is By discharging to a unique odor and pollutants generated during the disposal of food waste is effective. In addition, the household waste treatment apparatus according to the present invention does not need to be driven all the time, and when a certain amount of food waste is collected, it can be operated for a short time to obtain a desired result, and it can be operated only when livestock feed and organic fertilizer are quite economical. It will be called an invention.

In the above-described and illustrated example, the solidification-forming hole formed in the rotating plate 141 installed below the receiving chamber 140 has been described as being formed in a square shape, but the present invention is not limited thereto. Of course, it can be formed into a circle of 13.

Therefore, according to the household waste treatment apparatus according to the present invention, it can be used as an organic fertilizer because it is dehydrated and has a constant shape and a non-solid waste solid is formed. There is no need to store or collect food waste from the home separately, so that it can be disposed of immediately.

In addition, the water vapor that can be generated during the dehydration drying process is discharged to the outside, and most of the pollutants from the waste are removed during the drying process, and the excess pollutants are filtered out, so only the purified air is discharged to the outside. It has the effect of removing unique odors and pollutants generated at the time.

In addition, the household waste treatment apparatus according to the present invention does not need to be driven all the time, and when a certain amount of food waste is collected, it can operate for a short time to obtain a desired result. You can get it.
