Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a methane fermentation device with an improved structure of the input opening for kitchen waste.

Conventional Structure and Problems Therewith As shown in FIG. 1, the kitchen waste inlet portion of the fermentation device 1 generally includes an inlet 2, an inlet cover 3, and a cover rotating shaft (or hinge) 4.

In this case, when the worker opens the input port 3 during actual work, the water that has condensed on the inner surface of the input port 3 does not fall into the input port 2, but flows along the inner surface of the lid 3 to the outside of the lid 3 (for fermentation). (on top of the equipment 1) and may fall on the operator. Also, when putting in kitchen waste, the kitchen waste gets into the 4 parts of the lid rotation shaft,
If the opening/closing of the input port lid 3 becomes obstructed, or if it is left as it is, the kitchen waste will spoil outside the fermentation device 1 and emit a bad odor, which is unhygienic. Removal of kitchen waste that has entered the area will result in heavy work being required.

Purpose of the invention The present invention solves these conventional drawbacks and provides a methane fermentation apparatus that has a simple configuration and can process dew condensation water and smoothly input kitchen waste.

Structure of the invention The inlet of the methane fermentation apparatus of the present invention is equipped with a drain plate that covers the rotating shaft of the lid and guides condensed water from the inlet to the inlet when the inlet is opened. The drain plate prevents condensed water or kitchen waste from entering the rotating shaft of the lid.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 2, the inlet portion of the fermentation device 5 includes an inlet 6a, an inlet socket 6b, an inlet cover 7,
It is composed of a rotating shaft (or hinge, etc.) 8 of the input port lid 7, a draining plate 9, and a rotating shaft 10 of the draining plate 9. In addition,
Both sides of the draining plate 9 are U-shaped, and the tip is rounded. Further, the rotation shaft 8 of the input port lid 7 is supported by a support plate 11 provided on the fermentation device 5, and the rotation shaft 10 of the draining plate 9 is supported by a support plate 12 provided on the inner surface of the input port cover 7, respectively. 13 is a gasket fixed to the input port lid 7. The dashed line is the input port 7.
Shows the open state. In this state, the rotating shaft 10 side of the draining plate 9 is in contact with the inner surface of the input port cover 7. 14 is a cover plate provided on the input port lid 7 and covering the rotation shaft 10.

In this way, when the input port cover 7 is opened, water condensed on the inner surface of the input port cover 7 is guided into the input port 6a without flowing out through the drain plate 9. Also, when putting in kitchen waste, the draining plate 9 rotates downward and covers the rotating shaft 8 section of the input port lid 7, so the kitchen waste does not get into the rotating shaft 8 section. There is no problem in opening and closing the input port lid 7. Further, the kitchen waste that has entered the rotating shaft 8 does not rot and emit a bad odor, and the operator is freed from the task of removing the kitchen waste. Furthermore, by providing the drain plate 9, the inner surface of the input port cover 7 can be used as a part of the input port receptacle 6b. Further, since the inside of the input port cover 7 can be used as an extension of the input port receptacle 6b, it becomes easier for some workers to perform the task of inputting kitchen waste. In addition, when closing the input port cover 7 from the open state, since the tip of the draining plate 9 is rounded, it can be closed smoothly without hitting the input port 6a.

Effects of the invention As described above, the present invention is equipped with a drain plate that covers the rotation shaft of the input port and guides condensed water from the input port to the input port when the input port is opened. By preventing foreign objects from getting caught in the input port, the gutter maintains smooth opening and closing operations of the input port, and the gutter has the effect of introducing water that has condensed on the inner surface of the input port into the input port each time the input port lid is opened and closed. This frees the operator from troublesome and unhygienic work such as removing kitchen waste spilled outside the inlet, prevents the condensed water from scattering outside the inlet, and provides an inlet receptacle on the inlet lid. Because it can be used as a mouth,
This will greatly help improve input work.
