Abstract

<P>PROBLEM TO BE SOLVED: To provide a microbial degradation excreta tank capable of evenly agitating microbial proliferation bed without causing stress cracks at roots of agitator blades for a long operation. <P>SOLUTION: The agitation blades 16 for agitating the microbial proliferation bed 12 comprises: agitation blades 16a agitating while contacting a bottom face of the tank; agitation blades 16b attached at a slant to a rotation shaft; and agitation blades 16c for moving the growth bed 12 in the rotation shaft 15 direction and circulating it. The agitation blades are attached to the rotation shaft 15 via bosses 15b. By this configuration, the microbial growth bed 12 is evenly agitated, and microbial culture material is prevented from solidifying or sticking to the inner surface of the tank, moved, circulated and dispersed to activate growth of the microorganisms to promote decomposition of dung or urine. As the agitation blades are attached to the shaft via bosses without welding, breakage of that part caused by rusting and stress crack can be prevented. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a microbial decomposition toilet tank that decomposes and purifies manure by heating, moisturizing and stirring a microbial growth bed.

  In the microbial decomposition toilet tank 10 in which the present applicant forms in Japanese Patent Application No. 2002-164521, “the microbial growth bed 12 is formed, and the microbial growth bed 12 is heated, moisturized, and stirred to decompose manure, The stirring blade 16a that stirs all or part of the stirring blade 16 that is in contact with the bottom surface of the toilet tank 11 and the stirring blade 16b that stirs the middle layer of the microorganism growth bed 12 and the remaining stirring blade 16b. A microbe-decomposing stool (see FIGS. 5 and 6) with a scraper 22 made of a flexible material attached to the end of 16a was proposed.

  By the above proposal, the entire microbial growth bed can be agitated uniformly, and the culture material (wood chips, wood fibers) on which the microorganisms have been imbedded is uniformly heated, moisturized and dispersed without solidifying. The cause of inhibiting the growth of microorganisms was removed, and a certain evaluation was obtained from customers.

Thereafter, the following problems occurred in the course of long-term use.
A: Since culture materials such as wood chips and wood fibers constituting the microbial growth bed do not move and circulate in the stool, heating is performed depending on where the stirring ability of the stirring blade extends and where it does not. There is a difference in the moisturizing state and there is a difference in the decomposition state of manure.
B: Since the stirring blade is directly welded to the rotating shaft, the metal structure of the portion becomes coarse and easily rusts, and stress cracks may occur due to the concentrated attack of the corrosive components in manure, leading to breakage of the stirring blade. There is.

  In view of the above, the present invention uniformly stirs the culture material constituting the microbial growth bed, and further improves the heating and moisturizing state of the entire microbial growth bed so as to move and circulate in the stool. It is another object of the present invention to provide a microorganism-degrading toilet tank that does not break the stirring blade even during long-time operation.

  In order to solve the above-described problems, the present invention provides a stirring blade for stirring a microorganism growth bed in a microorganism-decomposing stool in which a microorganism growth bed is formed, and the microorganism growth bed is heated, moisturized, and stirred to decompose manure. Agitating while in contact with the bottom surface of the toilet tank, agitating the intermediate layer of the microorganism growth bed by being inclined with respect to the rotation axis of the stirring blade, and the direction of the rotation axis of the microorganism growth bed The stirring blade is attached to the rotating shaft via at least a boss, and has the stirring action of moving and circulating the microorganism growth bed in the direction of the rotating shaft. The stirring blade employs a configuration in which the attachment angle with respect to the rotating shaft can be adjusted.

  According to the present invention configured as described above, the stirrer blade that is attached to the bottom surface of the stool is prevented from sticking to the inner surface of the stool by the stirrer blade, and the stirrer blade that is attached to the rotating shaft is inclined. As a result, the stirring force propagates to any part of the middle layer, and the culture material is stirred and moved and circulated in an optimal state by the stirring blade attached so that the thrust works and the angle can be adjusted. Heating / moisturizing / dispersion is further improved, and the stirrer blades are not welded directly to the rotating shaft, but are attached with bosses. In addition, the concentrated attack by corrosive components in manure on the rusted portion was eliminated, and the problem of breakage of the stirring blade caused by the stress crack was solved.

  Next, an embodiment of the present invention will be described with reference to FIGS. Inside the toilet tank 11 is formed a microbial growth bed 12 into which wood chips, wood fibers (microorganism culture material), etc., on which microorganisms have been implanted are placed, and a heater 13 is disposed outside the bottom of the toilet tub 11, and the sled A water tank 14 is formed around.

  In the toilet tank 11, an agitating blade 16a attached to a rotating shaft 15 rotating in the direction of the arrow (inward from the outside with respect to each other) via a boss 15b so that the rotating end is in contact with the bottom surface of the toilet tank 11, a rotating shaft A stirrer blade 16b attached at an inclination to 15 and a stirrer blade 16c that moves and circulates the culture material constituting the microbial growth bed 12 (at least both ends are twisted in opposite directions) are respectively attached. A scraper 22 made of a flexible material is attached to the rotating end of the.

  The stirring blade 16a to which the scraper 22 is attached acts so that the culture material does not stick to the bottom surface of the stool 11, and the stirring blade 16b is attached to the rotating shaft 15 so as to be inclined to the middle layer of the microorganism growth bed 12. Stirring is performed throughout, and the agitating blade 16c is designed so that thrust is applied and the culture material is moved and circulated in the stool 11, so that the heating, moisturizing and dispersing of the culture material become uniform, and the excrement caused by microorganisms The decomposition of becomes active.

  A sheave 20 is attached to the rotary shaft 15 to which the agitating blade 16 is attached, and a cable wire 18 is wound around the sheave 20 and fixed. When the pedal 17 is depressed, the stirring blade 16 is rotated together with the rotating shaft 15, and the microorganism growth bed 12 is uniformly stirred.

  From the water tank 14, a toilet cleaning pipe 23 and a water supply pipe 24 for retaining the microorganism growth bed 12 are extended through pumps P1 and P2.

  As can be seen in FIG. 2 (the arrow view of FIG. 1), the cable wire 18 extending from the pedal 17 rotates the left and right rotating shafts via the sheave 20 and the gear mechanism 21. The cross section of the stool 11 is shaped along the rotational miracle of the stirring blade 16a so that the culture material does not stick to the inner surface of the stool 11 by the scraper 22.

  A heater 13 is attached to the outside of the bottom surface of the toilet tub 11, and the microorganism growth bed 12 is heated to 50 ° C to 80 ° C.

  FIG. 4 is a temporary toilet equipped with the microbial decomposition toilet tank 10 of the present invention, a solar power generation plate 26 is arranged on the ceiling, and the generated electric power is stored in a battery (not shown) and used for indoor lighting at night.
