Description

Crusher device of refuse}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste disposal apparatus, and more particularly, to a waste disposal apparatus in which food waste or other moisture-rich wastes are pulverized and dried in a vertical type vertical grinder to greatly reduce the volume. .

Generally, the garbage disposal device is to reduce the weight and volume of garbage by evaporating and drying the moisture contained in the polluted waste that is discharged from ordinary homes or restaurants. By incineration and microbial fermentation.

Among them, the incineration treatment apparatus currently used is a method of directly heating food waste, and when the water content of the food waste to be treated is high, it consumes a lot of energy and treatment cost, and also generates smoke and odor generated during incineration. Due to this, there is a disadvantage that secondary pollution occurs.

In addition, the fermentation food waste treatment apparatus is a method to reduce the volume by biologically fermentation decomposition by putting microorganisms having a decomposition characteristics for food waste into the food waste is loaded, but this is a slow processing speed of food waste and odor Has the disadvantage that occurs.

In addition to the two methods described above, there is a dry pulverization treatment method for crushing and drying waste, and as an example of the prior art, as shown in Korean Patent Registration No. 202428, 'Food Waste Treatment Device', food waste is transported and stirred. In addition to the application of heat and dry treatment method is adopted,

In addition, as another example of the prior art, 'Food Waste Disposer (Application No. 99-39283)' filed on September 15, 1999 by the same applicant is used to grind the waste containing a lot of water with a grinder and pulverize the waste. By separating the waste into liquid and sludge and drying to drastically reduce the volume, the waste can be processed quickly and the weight and volume can be drastically reduced.

In the conventional food processing apparatus having such a configuration, since the grinder is installed in a horizontal state, the waste that is supplied drop from above is subjected to a process of being crushed while passing through the blade of the grinder that is rotated.

Therefore, the conventional food waste treatment apparatus has a disadvantage in that the grinding efficiency is lowered during the crushing process of waste, and thus, the drying efficiency of the waste is also reduced.

In addition, the conventional food waste treatment apparatus has not only a difficult separation process for separating waste into sludge and liquid, but also has a disadvantage in that energy and processing time are consumed in a drying process for separating waste.

The present invention was made in view of the above-mentioned problems, and an object thereof is to shorten the treatment time of garbage containing a lot of water, and to reduce the energy consumption and volume of the garbage disposal apparatus. To provide.
