[0003]

However, in the prior art, there is a problem that the heating efficiency is low and the processing takes time because of heating by the electric heater.

[0004] The present invention has been made in view of such conventional problems, and provides an organic waste treatment system and an organic waste treatment vehicle which can efficiently treat the waste in a short time. It is an object.

[0005]

In order to achieve the above object, an organic waste treatment system according to the present invention has a fermenter, a boiler, and a hopper, and the fermenter has a steam tank and a fermenter. A steam tank having a steam inlet and a steam discharge port, the fermentation tank being housed inside the steam tank, a waste inlet and a treated material An outlet, wherein the shaft extends through the fermenter and is rotatably provided by power;
The stirring fin is radially fixed to the shaft, the boiler has a steam discharge port connected to a steam intake port of the steam tank, and the hopper is A rotating blade connected to a processing material outlet of the tank and provided at the opening or inside of the shaft to rotate with the rotation of the shaft and to promote the passage of steam in the shaft is provided.

An organic waste treatment vehicle according to the present invention is characterized in that the organic waste treatment system according to claim 1 is integrally mounted.

[0007] A deodorizer is preferably connected to the fermenter. The fermentation tank is preferably divided into two tanks. It is preferable that the hopper and the processed product outlet of the fermenter are connected by a conveyor. The organic waste treatment vehicle is preferably equipped with a generator. The opening or the inside of the shaft is provided with a propeller or other rotating blade that rotates with the rotation of the shaft so as to promote the passage of steam through the shaft.

[0008] In the organic waste treatment system and the organic waste treatment vehicle according to the present invention, when the organic waste is treated, the organic waste is introduced into the waste inlet of the fermenter.
The steam generated by the boiler is sent from the steam outlet to the steam inlet of the steam tank, and the steam tank heats the internal fermentation tank by the steam. Inside the fermenter, the shaft and stirring blades rotate to stir the organic waste inside. The steam in the steam tank is also sent to the inside of the shaft to increase the heating efficiency inside the steam tank. The organic waste in the fermenter is dried and sterilized by heating, and fermentation bacteria are added to promote fermentation. The processed product after fermentation is sent to the hopper from the processed product outlet of the fermenter. The processed product is bagged as fermented fertilizer from a hopper.

Further, the organic waste treatment vehicle according to the present invention can be freely moved to a place where the treatment of the organic waste is required and treated.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. As shown in FIG. 1, the organic waste treatment vehicle 1 is integrally equipped with an organic waste treatment system. The organic waste treatment system is a fermenter 2
, A deodorizer 3, a boiler 4, and a hopper 5.

As shown in FIG. 2, the fermenter 2 has a steam tank 6, a fermentation tank 7, a shaft 8, and a stirring blade 9. The steam tank 6 has a steam inlet 6a and a steam outlet 6b.
And sealed. The fermentation tank 7 has a steam tank 6
Is housed inside. The fermentation tank 7 is divided into two tanks, each of which has a waste inlet and a processed material outlet. The shaft 8 penetrates the fermenter 7. The shaft 8 is rotatably provided by a generator 10 mounted on the organic waste treatment vehicle 1. The shaft 8 is tubular and has both ends communicating with the steam tank 6. A plurality of the stirring blades 9 are radially fixed vertically to the shaft 8.

The deodorizer 3 is composed of an ozone deodorizer and is connected to the fermenter 7 to deodorize the odor generated in the fermenter 7. The boiler 4 has a steam outlet connected to a steam inlet 6 a of the steam tank 6. The hopper 5 is connected to a processed product outlet of the fermenter 7 via a screw conveyor 11. The deodorizer 3 and the screw conveyor 11 are:
It is driven by the generator 10. The organic waste treatment system mounted on the organic waste treatment vehicle 1 is surrounded and accommodated by a wing 12 that can be opened and closed.

Next, the operation will be described. The organic waste treatment vehicle 1 can freely move to a place where the treatment of the organic waste is required and treat it. Organic waste suitable for treatment is sludge from agricultural settlements, sludge discharged from food factories such as okara, and household residues. Organic waste treatment vehicle 1
When treating organic waste with an organic waste treatment system mounted on a vehicle, first, the organic waste is put into a dehydrator mounted on another vehicle. 8 organic waste by dehydrator
Centrifugal dehydration to a dehydration rate of about 0 to 85%. The dehydrated product taken out of the dehydrator is put into the waste inlet of one of the two fermenters 7. In the other fermenter 7, the dehydrate is put in a one-day cycle.

The steam generated by the boiler 4 is sent from a steam outlet to a steam inlet 6a of a steam tank 6, and the steam tank 6 heats an internal fermenter 7 by the steam. Inside the fermenter 7, the shaft 8 and the stirring blade 9 rotate to stir the organic waste inside. The steam in the steam tank 6 is also sent to the inside of the shaft 8 to increase the heating efficiency inside the steam tank 6. The organic waste inside the fermenter 7 is 80
It is dried and sterilized by heating at a temperature of ~ 90 ° C, and fermentation bacteria are added to promote the fermentation at a temperature of 60 ~ 80 ° C. The odor generated in the fermenter 7 is deodorized by the deodorizer 3.

The processed product after fermentation is sent to the hopper 5 by the screw conveyor 11 from the processed product outlet of the fermenter 7. The processed product is bagged from the hopper 5 by the bagging device 13 as fermented fertilizer. According to this organic waste treatment system, organic waste can be efficiently treated in about 48 hours.

[0016]

According to the organic waste treatment system and the organic waste treatment vehicle according to the present invention, the organic waste can be efficiently treated in a short time. In addition, rotating blades that rotate with the rotation of the shaft are provided in the opening or inside of the shaft to promote the passage of steam in the shaft. In particular, according to the organic waste treatment vehicle according to the present invention, the vehicle can be freely moved and treated.
