JP2000070176A - Septic tank of microbial degradation type - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a septic tank of a microbial degradation type wherein excrements are evenly dispersed in a culture medium in which soil microorganisms live, and hence the excrements can be effectively decomposed. SOLUTION: Turning forces are transmitted from a motor with reduction gear 11 to two rotation axes 14 in a septic tank 10 through a chain 12 and a sprocket 13. A plurality of mixing blades 15 are mounted on each axis 14. The mixing blade 15 is formed in such a manner that slits are formed radially in a disk-like material and each slit is then extended intermittently along a boss 16 so that a portion, wherein the slit is formed intermittently, is formed and such portions are bent at any angle alternately in opposite directions. If the blades 15 are randomly spaced apart and at an angle, excrements are mixed into globular culture mediums, and if the axes 14 are oscillated in the axial direction, the excrements can be mixed much better.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of storing wood chips, sawdust or plant cuttings (hereinafter simply referred to as culture media) inhabiting soil microorganisms (hereinafter simply referred to as microorganisms) in a toilet tank. The present invention relates to a microbial-decomposition type toilet tub that decomposes excrement by heating a temperature at which the activity of soil microorganisms is activated (hereinafter referred to as an activation temperature) while agitating the granular medium and excrement.

[0002]

2. Description of the Related Art As shown in FIG. 4, excrement is guided to a toilet tank 2 containing a culture medium 1 in which microorganisms inhabit as a microbial decomposition type toilet tank, and the excrement is evenly dispersed in the culture medium 1. In such a case, the excrement is decomposed by stirring with a stirring blade 3 and heating to an activation temperature by a heater (not shown).

[0003]

As a result of repeated tests of the above-mentioned proposals under actual use conditions, if the stirring blades are always rotating along the same trajectory, a blind spot area where stirring cannot be reached will be defined. It was found that when excrement enters the blind spot area, the excrement is combined with the following excrement and gradually becomes a large lump, which is not decomposed forever and causes a bad smell.

[0004] Based on the above findings, the present invention intends to provide a microbial decomposition type toilet tank in which excreta are evenly dispersed in a medium contained in the toilet tank and decomposed efficiently. .

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a method for introducing excrement into a toilet tank containing a granular medium in which soil microorganisms inhabit, and stirring the excrement to form a culture medium. In a microbial-decomposition type toilet tub that disperses and disperses excrement by heating to a temperature that activates the activity of the soil microorganisms, a stirring blade is arranged in the toilet tub so that a blind spot of stirring does not occur. Wherein the stirring blade is attached to a plurality of rotating shafts, and the stirring blade is bent at an arbitrary angle with respect to the rotating shaft about a line perpendicular to the rotating shaft, At least one of the rotating shafts is configured to swing in the axial direction.

[0006] Further, a hopper for guiding excrement together with the culture medium into the cylinder, a propulsion wing for pushing out the excrement guided into the cylinder and the culture medium to the downstream side, and a culture medium for excreting extruded together with the culture medium. A crushing / extruding mechanism having crushing wings for dispersing in the base is provided, and the excrement dispersed in the culture medium extruded by the crushing / extruding mechanism is circulated through the cylinder.

In the present invention constructed as described above, since the stirring is performed by the stirring blade which does not form the blind spot area of the stirring, the undecomposed excrement does not collect to form a large mass, and the excrement is contained in the culture medium. The dispersal becomes uniform and the decomposition proceeds effectively.

[0008]

Next, embodiments of the present invention will be described with reference to the drawings. To the toilet tub 10, rotational force is transmitted from a motor 11 with a speed reducer to two rotary shafts 14 via a chain 12 and a sprocket 13. A plurality of stirring blades 15 are attached to each rotating shaft 14. In addition, 18 is a cover of a drive part, and 19 is a floor plate to which a toilet is attached.

The stirring blade 15 radially slits a disk-shaped material, and continuously extends from the base of the slit to the boss 1.
6 are intermittently slit, and the portions are bent at an arbitrary angle in the opposite direction to each other.
If the installation interval and bending angle are set at random, the excrement mixes well with the culture medium. Further, when the rotating shaft 14 is swung in the axial direction, the mixing is further improved.

[0010] In addition to the above embodiment, as a second embodiment,
A plurality of bosses 16 are fixed to the rotating shaft 14,
A bar 17 (which may be a round bar, a square bar, or a flat bar) is radially implanted into a stirring blade 15 ', and the stirring blade 15'
It is also possible to adopt a configuration in which the rotating shaft is swung in the axial direction while rotating the rotating shaft.

As a third embodiment, a hopper 2 for receiving the excrement 21 in the toilet tank 10 containing the culture medium 22 is provided.
The excrement 21 is introduced into the cylinder 23 via the hopper 24 together with the culture medium 22, and the excrement 21 is collected by the propulsion wings 25 provided in the cylinder 23. And crushing wings 26
The excrement 21 may be dispersed in the culture medium 22 while crushing, and the excrement 21 finely dispersed in the culture medium 22 may be circulated through the cylinder 23 together with the culture medium. Reference numeral 27 denotes a crushing and dispersing mechanism including the cylinder 23, the propulsion wing 25, and the crushing wing 26; 28, a screw shaft for driving the propulsion wing 25 and the crushing wing 26; 29, a geared motor for driving the screw shaft.

[0012]

As described above, according to the present invention, the dead zone of agitation in the stool layer is eliminated, excreta is mixed with the medium in which soil microorganisms have inhabited, and decomposition by microorganisms is not biased. Proceed effectively.
