Description

Apparatus for disposing food, s waste matters

The present invention relates to a food waste processing apparatus, and more particularly, to a food waste processing apparatus having a double cutter composed of a cutter and a screw mill in order to easily grind a solid object in the food waste.

In recent years, households have been struggling with the disposal of wet garbage due to the prohibition of bringing in wet garbage to landfills. As a countermeasure, in order to dispose of food waste left after cooking or after meals, each household is processing food waste in a garbage bag after drying food waste in a place such as a balcony of an apartment in the house.

However, as mentioned above, drying of wet food waste causes odors, causing odors to vibrate and discomfort in the house, and can also cause disease by wet food waste in the summer when it rains frequently. A problem arises.

In order to dispose of these food wastes, a "fast composting device for food wastes", filed on February 5, 1993 and published in Utility Model Registration Publication No. 95-7395 on September 11, 1995, has been proposed.

The above-mentioned "high-speed composting device of food waste" is a fast composting of food waste by promoting the fermentation by the introduction of aerobic microorganisms in consideration of the complex fermentation fixing or drying process of food waste and low maturation of fermentation.

For this purpose, the "high-speed composting device of food waste" described above, as shown in Figure 1, the waste generated from a variety of food and various sludge and organic waste is introduced into the low temperature fermentation device 101 through the inlet 106 The waste introduced into the low temperature fermentation apparatus 101 and various sludges and organic wastes are rotated by the rotation of the rotary shaft 107 in the stirring vessel 101a provided in the low temperature fermentation apparatus 101 and the rod 109. Is stirred.

The rod 109 is for removing foreign matters attached to the wall of the stirring vessel 101a from the wall, and waste and various sludges and organic wastes are stirred and supplied at a low temperature by supplying a certain amount of aerobic microorganisms in the stirring vessel 101a. Fermented.

The waste fermented at low temperature in the low temperature fermentation apparatus 101 and various sludges and organic wastes are transferred to a warm jacket 111 supplied with steam at 150 to 200 ° C. by a transfer screw 102 formed of a spiral screw. In 111, garbage and various sludges and organic wastes are moved outwards by centrifugal force by a spiral blade 113 provided on a stirring shaft 112 installed upright in the warm jacket 111, and heated by steam. The heating surface 111a of the heated jacket 111 is uniformly contacted and dried.

In addition, the spiral screw 103 which is operated by the motor 104 to discharge the high temperature fermentation-dried waste to the discharge port 105 is installed on the side of the warm jacket 111, the waste jacket and the top of the warm jacket 111 Deodorizer 110 is installed to remove odor generated during the treatment of various sludges and organic wastes, and the dried food waste is discharged through the outlet 105 by the spiral screw 103 and is generated during drying. The odor is removed by the deodorizer 110.

According to the conventional food waste treatment apparatus as described above, after the food waste having moisture is low temperature fermented in the low temperature fermentation apparatus 101, the food waste is transferred to the warm jacket 111 of the high temperature fermentation and drying apparatus by the transfer apparatus 102. And dried by steam at 150 to 200 ° C. in the warming jacket 111 to achieve high temperature fermentation and water evaporation, and such work is continuously performed to enable high-speed composting.

However, as described above, in the conventional food waste processing apparatus, when the food waste is put into the low temperature fermentation apparatus, when the food waste is stirred by a stirrer, a dead zone does not reach the stirring rod, and therefore, it takes a long time to ferment the food waste. Therefore, there is a problem that the size of the device is increased due to unfermented food waste as well as the treatment efficiency is not reduced.

In addition, the conventional food waste treatment apparatus as described above is for composting the food waste by only fermenting the waste, there is a problem that it is almost impossible to reduce the volume of the waste.

In order to eliminate such a problem, the application utility No. 97-57093, filed August 25, 1997, published by the present inventors, published on November 10, 1997, as shown in FIG. (2), a pulverizer (3) for crushing the food waste introduced through the inlet (2), a pressurizing chamber (4) for pressing and storing the crushed food waste to a predetermined size, discharge for discharging the pressurized food waste When the food waste is discharged by the cylinder 12, the discharge cylinder 12, the opening and closing cylinder 15 for opening and closing the discharge port 16, and waste water generated when the food is pressurized in the pressure chamber (4) Wastewater treatment chamber 11 for

The pulverizer 3 is located in the lower portion of the inlet and is formed in a spiral shape having a pulverization blade. When the inlet 2 is closed, the pulverized food waste is pulverized and the pulverized food waste is pushed in one direction. The pressurization chamber 4 is provided with a pressurized cylinder 5 for pressurizing the crushed food waste to a predetermined size, and has a drain 9 for discharging water generated by the compression of the food waste. The inlet 2 is adapted to be connected to the power supply to shut off the power supply to the device 1 when it is opened and to supply power to the device 1 when it is closed.

The discharge cylinder 12 is installed at the lower side of the pressurizing chamber 4 to discharge the food waste pressurized to a predetermined size by the pressurizing cylinder 5 to the outside, and the switch 13 is connected to the discharge cylinder 12. It is installed on the opposite side and is operated simultaneously with the discharge cylinder 12 to open the slat conveyor 18 of food waste discharged by the discharge cylinder 12 to the discharge port 16.

The wastewater treatment chamber 11 communicates with the drainage port 9 of the pressurization chamber 4, stores moisture (wastewater) discharged from the drainage port 9, and accommodates microorganisms for decomposing contaminants in the stored moisture.

However, since the food waste disposal apparatus as described above has a grinder formed in a spiral shape, the foreign matters of small size mixed with the food waste are easily crushed, but are relatively large such as animal bones or fish thorns that may be mixed in the food waste. Difficult to crush hard foreign matter.

Accordingly, an object of the present invention is to easily grind relatively large and hard foreign matter mixed in food waste, and to have a structure that can easily transport the ground foreign matter, while reducing the volume of food waste to occupy a large volume. It is to provide a food waste processing apparatus that can reduce the waste disposal costs due to food waste.
