Description

Food waste disposal apparatus

The present invention relates to a food waste treatment apparatus, and more particularly, to improve foreign matter removal efficiency and food waste shredding efficiency, and to prevent unnecessary load from being applied to a drive unit that rotates a blade that shreds food waste. It relates to a food waste disposal apparatus that can reduce noise in the workplace.

Recently, the rapid increase of industrial development and the increase of waste emission due to population increase have been pointed out as a serious environmental pollution factor.

Among these wastes, especially food wastes emitted from homes, restaurants, and food manufacturing plants produce severe odors, which are not only pollution in themselves, but also pollute water quality by promoting eutrophication of water when flowing into rivers. Causes serious problems such as back.

On the other hand, since these food wastes contain a large amount of water, they are difficult to collect and transport, are difficult to incinerate, and require a large amount of processing. Thus, landfills have been used for simple soil reclamation. There is a limit that it is not a method of causing secondary environmental pollution such as pollution and fundamentally treating food waste.

In order to solve this limitation, recently, a method of fermenting food waste or decomposing it into microorganisms has been used. However, such fermentation or decomposition quenching treatment method removes foreign substances such as plastic and metal cans, which are frequently included in food trash, from food trash before fermentation or decomposition quenching treatment, and quickly fermentation or decomposition quenching of food trash. It includes a process of crushing finely to be processed.

1 and 2 are a front view and a side view showing a conventional food waste processing apparatus for performing the operation of selectively removing the foreign matter from the food waste and finely crushing the food waste.

In the conventional food waste treatment apparatus, a crushing region 11 in which food waste introduced through the hopper 11-1 is accommodated and a storage region 12 in which the crushed food waste falls are accommodated and provided therein. The treatment tank 10, the rotary shaft 20 is provided with a plurality of blades 21 along the outer circumferential surface, the drive unit 30 for driving the rotary shaft 20, the shredding region 11 is provided on one side of the food waste contained in The blower 40 blows foreign matters to the other side of the shredding region 11 and the ejector 50 discharges the foreign matters blown to the other side of the shredding region 11 to the outside of the treatment tank 10.

In such a conventional food waste treatment apparatus, the food waste introduced into the shredding area 11 is crushed by the blade 21 of the rotating shaft 20, and the finely crushed food waste is formed in the porous wall 13 13-1, and falls into the storage area 12, and is discharged through the discharge port 12-1.

In this crushing process, the light foreign matter of the synthetic resin such as vinyl contained in the food waste is blown by the wind of the blower 40 is transported to the discharger 50 side. In addition, heavy debris that is not broken, such as a metal can, is pushed by the food waste introduced on the partition 13 and transported to the ejector 50. The foreign matters transferred to the discharger 50 side are discharged to the outside of the treatment tank 10 through the foreign matter discharge port 51 by the discharger 50.

However, in the conventional food waste treatment apparatus, there is a problem that a light foreign material of synthetic resin such as vinyl is frequently caught or stuck to the rotating blade 21.

When the foreign matter is caught or adhered to the blade 21, the foreign matter is not discharged to the outside through the ejector 50, the foreign matter removal efficiency is lowered, as well as rotates the blade 21 by the caught or adhered foreign matter There is a disadvantage in that an unnecessary additional load is applied to the rotating shaft to cause abnormal noise.

For this reason, the power consumption of the food waste processing apparatus is unnecessarily increased, and the noise level of the workplace is increased, thereby reducing the work efficiency of the worker.

In addition, when foreign matter is caught on the blade 21, the foreign material is wrapped around the blade 21, so that the blade 21 is not in direct contact with food waste, there is a disadvantage that the shredding efficiency for food waste.

In addition, since the wind of the blower 40 does not reach enough to reach the ejector 50 far from the blower 40, foreign matters may not be quickly transferred to the ejector 50, and thus the discharge efficiency may be lowered.

In addition, in the conventional food waste treatment apparatus, heavy foreign matter that is not broken, such as a metal can, is pushed by the inflow force of the food waste flowing into the shredding region 11 and transferred to the ejector 50. According to the kind, it is very easily crushed and quickly falls into the storage area 12, so that the inflow force of food waste is not sufficiently transmitted to the foreign matters, which also lowers its discharge efficiency.
