Abstract

PROBLEM TO BE SOLVED: To prevent the dislodgment of agitating vanes under operation by boring a revolving shaft driven by a driving mechanism in a reaction vessel in which microorganisms and microorganism medium agents are housed with plural through-holes in a zigzag form at a prescribed interval and set angle and mounting the agitating vanes at these through-holes. SOLUTION: The agitating mechanism of the garbage treating device which mixes and agitates the microorganisms with the garbage is constituted by mounting the agitating vanes 2 at the revolving shaft 1. A suitable number of notched parts 5 and the through-holes bored in these notched parts 5 are formed at the revolving shaft 1. These notched parts 5 and the through-holes are arranged zigzag in such a manner that mounting shafts 3 adjacent to each other have an angle of about 135 deg. with each other. After the mounting shafts 3 are inserted into the through-holes, nuts are screwed to the threaded parts of the mounting shafts 3, by which the mounting shafts are tightened and fixed to the revolving shaft 1. If the mounting shafts 3 are inserted into the through-holes in such a manner and are screwed and fixed by means of the nuts, the occurrence of such accident that the agitating vanes 2 are dislodged from the revolving shaft 1 to hinder the operation is surely prevented.

2. Description of the Related Art Conventionally, there are various techniques for treating food waste generated from various fields such as households, and one of the means is to mix and stir the microorganisms with the food waste, and to mix the microorganisms with the enzyme. There is one that decomposes the food waste into water and carbon dioxide by a synergistic action.

[0003]

This means is to put raw garbage into a reaction tank containing a biomicroorganism mainly consisting of aerobic bacteria and a microbe consisting of biowood, and then throwing the raw garbage into the reaction tank and mixing / mixing. It is extremely effective as a means for treating food waste because it decomposes the food waste into water and carbon dioxide gas by stirring and extinguishes it, but the conventional technique is that when the stirring blade is radially extended from the rotating shaft. , As shown in FIG.
Since the rotary shaft is sandwiched and fixed to the shaft, there is a possibility that the mixture and agitation of the mixture of the food waste and the microbial medium agent may not be carried out uniformly. Due to the resistance, the stirring blade may come off from the rotating shaft, which may hinder the processing work.

An object of the present invention is to make the mixing and stirring uniform based on the above causes and to prevent the stirring blade from being separated from the rotating shaft.

[0005]

[Means for Solving the Problems] That is, the present invention is a raw material in which raw garbage is put into a reaction tank, and the introduced raw garbage is decomposed into water and carbon dioxide gas by the microorganism and the microbial medium agent contained in the reaction tank. In the waste treatment device, a rotary shaft driven by a drive mechanism is provided in the reaction tank, and a plurality of through holes are formed in a zigzag shape at a predetermined interval and a set angle (about 135 °) in the rotary shaft. The above problem is solved by adopting a structure in which a mounting shaft of a stirring blade is inserted into the through hole and an end portion of the shaft is screwed.
