Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for producing compost using organic waste, mainly animal manure such as raw manure, as a raw material.

As is well known, moisture adjustment is an important issue in composting this type of organic waste, and in the past, sawdust was mixed in for this adjustment.

However, with such means, there are problems such as an increase in processing costs due to the recent difficulty in obtaining sawdust, and a decrease in processing efficiency due to the fact that the rate of fermentation and decomposition of sawdust is longer than that of manure.

The present invention aims to provide a compost manufacturing apparatus that can solve these problems.

The apparatus of the present invention will be explained below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a horizontally long exterior body, which houses therein a transport mechanism 2, a groove 3 as a liquid collection means, and a cut section 4 as a raw material stirring means.

Furthermore, inside the exterior body 1, there may be provided an evaporated water recovery gutter 5 and a dispersion pipe system 6 as a means for dispersing organic waste liquid, if desired.
The collection gutter 5 communicates with an external drainage channel (not shown), and the dispersion pipe system 6 is configured to spray the liquid collected in the channel 3 onto the raw material to be transported.

The exterior body 1 is formed long above the ground by, for example, sequentially connecting tunnel-shaped exterior units 11 of a predetermined length, and its roof portion 12 is formed in whole or in part as a transparent surface 13. There is.

It is desirable that the roof portion 12 has a convex curved surface as in the embodiment, and if so, as shown in FIG.
The evaporated water recovery gutter 5 is provided on both sides of the inner surface of the roof part 12, and water droplets condensed on the inner surface of the roof part 12 can be made to drip into the recovery gutter 5 along the inner surface of the roof part.

The transparent surface 13 is provided to heat the raw material 7 inside by solar heat and thereby evaporate the moisture in the raw material 7.

Therefore, it is unavoidable that the moisture content of the raw material 7 varies considerably between summer and winter, so for example, a light-shielding lid (not shown) may be provided on the light-transmitting surface 13 to increase or decrease the area of the light-transmitting surface 13. It is desirable to configure it in the same way.

Particularly in the case of large equipment where the length of the exterior body 1 exceeds 10 m, there is also a relationship with the raw material conveyance speed.
It is desirable to provide the roof portion 12 of the exterior body 1 with a partial non-light-transmitting surface.

An elongated tunnel-shaped processing chamber 14 is formed inside the exterior body 1, and a raw material input section 15 is provided at one end of the processing chamber 14, and a discharge section 16 is provided at the other end.

A conveyance mechanism 2 for conveying the raw material 7 inputted from the input section 15 to the discharge section 16 is installed inside the processing chamber 14, and all or a part of this conveyance mechanism 2 is configured as a deliquification path 21. ing.

The liquid removal path 21 includes a pair of belt conveyors 22,
23 are mounted in parallel along the conveyance direction, and the approach side of the belt conveyors 22 and 23 is lower than the other side, so that both conveyors 22 and 23 form a road surface with a V-shaped cross section. be.

The liquid removal path 21 is usually formed to vertically face the light-transmitting surface 13, but it is not necessarily limited to this.

At the bottom of this V-shaped liquid removal path 21, a groove path 3 as a liquid collection means is provided along the liquid removal path 21,
The liquid leached from the raw material on the draining path 21 is collected in the channel 3 and is stored at a predetermined location by the drain 31.

It is desirable that the belt conveyors 22 and 23 be constructed using porous belts such as net belts, and in this way, the liquid content will also seep out from the holes in the belts, so that the liquid removal process will be improved.

In this case, as shown in FIG. 2, it is desirable to extend the receiving plate 25 in an inclined manner below the belt conveyors 22, 23 to guide the leachate to the channel 3.

As described above, when the belt conveyors 22 and 23 are made of porous belts, compressed air can be blown up from inside the belt conveyors to supply oxygen to the raw material 7.

That is, it is necessary to supply oxygen to the raw material 7 in the processing chamber 14, but in this case,
As shown in FIG.
3) If a fume section 8 is provided as an oxygen supply means inside the reactor, the supply of oxygen to the raw material 7 can be improved.

Further, in the processing chamber 14, a stirring means for stirring the raw material 7 to increase the contact area with air is provided.
is used.

The above-mentioned cutting section 4 may mix the raw materials 7 in the vertical direction, for example, as shown in FIG. 5, the belt conveyor 2
A rotary feed member 41 may be provided between the belt conveyors 2 and 24, or a head 42 may be provided between the belt conveyors 22 and 24 as shown in FIG.

The above-mentioned dispersion pipe system 6 is for dispersing the urine component obtained from the raw material 7 onto the raw material 7, and this spraying is performed to replenish and adjust the liquid content of the raw material 7 when it becomes too small.

Therefore, if the design is designed to increase water evaporation from the raw material 7 and add a large amount of urine to the raw material 7, it is possible to improve the quality of the compost and treat the urine at the same time. In this way, the apparatus of the present invention utilizes water evaporation due to solar heat and liquid recovery through the dewatering path 21 to remove the raw material 7.
Since it adjusts the liquid content of the compost, it is possible to solve the problems mentioned above in conventional composting processing, and the temperature inside the processing chamber required for fermentation can be obtained from solar heat, which also has the effect of saving energy. There is.
