Description

Organic material processing device

The present invention relates to an organic matter treatment apparatus for decomposing organic matter such as kitchen waste by the action of microorganisms.

As one method for treating organic matters such as kitchen waste generated in kitchens of general households and restaurants, there is a method using decomposition by microorganisms.

The organic material treatment apparatus according to this method is configured by providing an inlet in the upper part of a treatment tank for accommodating microorganisms for decomposing organic matter and carriers of the microorganisms (small pieces of wood, sawdust, activated carbon, etc.) and arranging stirring means therein. The organic material introduced into the treatment tank through the inlet is mixed in the carrier by the operation of the stirring means, and left in this state to decompose by the activity of the microorganisms reproduced in the carrier.

In order to improve the decomposition of the organic matter contained in the carrier, it is necessary to supply an appropriate amount of air (oxygen) in the carrier which contains an appropriate amount of water, and maintain the inside of the carrier in an environment suitable for the activity of microorganisms. It is important to provide a ventilation means inside the treatment tank and a heating means to supply external air into the treatment tank by the operation of the ventilation means, and to discharge the moisture and gas generated by the decomposition out of the treatment tank, While maintaining an appropriate amount of air and moisture inside, while maintaining the inside of the treatment tank at a proper temperature by the heating operation of the heating means, and again by the operation of the agitating means, the carrier is frequently agitated to provide air into the carrier. At the same time, the operation of maintaining the internal environment of the treatment tank is performed by releasing water and gas generated by decomposition. .

By the way, in this kind of organic matter treatment apparatus, in accordance with the continuous operation proceeded as described above, the residue of the decomposition treatment portion and the hardly decomposed matter (vinyl bag, disinfection bottom, clamshell, etc.) introduced together with the organic matter are added to the inside of the treatment tank. Since the reproductive environment of microorganisms gradually accumulates in the carrier and degrades the processing capacity, it is necessary to draw the carrier in the treatment tank at a suitable cycle and replace it with a new carrier.

As disclosed in Japanese Patent Laid-Open No. 7-136627 (B09B 3/00), Japanese Patent Laid-Open No. 7-222967 (B09B 3/60), and the like so as to facilitate the above-mentioned carrier exchange, The carrier discharge outlet can be opened and closed freely by the shutter under one side (front side) of the treatment tank, and when the carrier is replaced, the carrier inside the treatment tank can be easily pulled out by removing the shutter and opening the outlet. Adopted.

However, when the outlet of the carrier is provided on the bottom of the treatment tank, it is inevitable that the strength of the peripheral edge of the opening part of the outlet decreases, and the weight of the carrier in the treatment tank and the stirring force of the carrier by the stirring means are inevitable. Due to the action, the circumferential edge portion of the discharge opening is bent, and there is a problem that the closure by the shutter is not smooth.

This problem can be alleviated by forming a reinforcing rib on the circumferential edge of the outlet, on the outer surface side or the inner surface side of the treatment tank, but when the reinforcing rib is installed on the outer surface, interference with the shutter must be avoided. In the case of mounting in the air, the agitation of the carrier due to the operation of the stirring means may be inhibited.

For this reason, conventionally, the thickness of the entire treatment tank is increased and the circumferential edge of the discharge port is made thicker than other parts to cope. However, such a treatment tank is a large volume hollow container, and its molding is performed. The mold form of the dragon is complicated, and there is a disadvantage that causes an increase in the total weight.

The present invention has been made in view of such circumstances, and the circumferential terry portion of the carrier discharge port provided at the bottom of the treatment tank can be strengthened without treatment at the treatment tank side, and effectively prevents warping due to the weight and stirring force of the carrier. It is an object of the present invention to provide an organic material treating apparatus which can maintain a closed state by a shutter for a long time.
