Description

[Detailed Description of the Invention] The present invention relates to an organic substance fermentation device that supplies air to fertilizer, feed, etc. to promote aerobic fermentation.

Conventionally, this type of fermentation equipment for organic substances such as fertilizer and feed was (
a) A method for high-temperature aerobic fermentation by inserting a ventilation pipe into a hollow rotating body and supplying organic substances such as compost and feed with air.
(b) A method in which a stirrer is moved through the organic material to bring it into contact with air; (C) A method in which a blade or screw is rotated in a fixed cylinder to send out the organic material while stirring, etc. are used; (a) In this case, if more than 50% of the organic material is placed in the rotary drum, the rotation of the organic material will stagnate and the organic material will form lumps inside, making it difficult for it to come into contact with the air, making it impossible to process a large amount at once.

In addition, (b) has the disadvantage that it takes too much time.

Next, in the case of (C), the contact between the organic substance and the air is good and the processing time is short, but it requires a large amount of power to rotate the heavy object with a blade or screw, which is unsuitable from the viewpoint of energy saving. .

In view of the above-mentioned problems, the present invention is designed to send out the fermentation material made of organic substances in one direction using the feeding blades arranged spirally on the inner circumferential surface of the hollow rotary cylinder, while a large number of ventilation holes are fixed at the center of the feeding blades. Feather pieces are protruded radially from the open ventilation pipe,
These blade pieces were arranged in multiple stages in the length direction of the ventilation pipe, and by rotating the blade pieces as the rotating cylinder rotated, stirring was achieved with less power, and the ventilation hole was located on the underside of the blade piece. In order to prevent blockage caused by the material to be fermented and to ensure effective ventilation, the reversing plate inserted along almost the entire length in the length direction ensures that the heavy fermented materials are mutually aligned along the entire length as the rotating cylinder rotates. This is to invert it.

Next, the configuration of an embodiment of the present invention will be explained with reference to the accompanying drawings.

1 is a long hollow rotating cylinder, and this rotating cylinder 1 is attached to a frame 2.
It is rotatably supported by rollers 3 on the top.

A sprocket gear 4 is fixed to the outer periphery of the rotating cylinder 1 and is driven by an electric motor 6 via a chain 5.

Further, a ventilation pipe 7 is inserted along the entire length of the rotating cylinder 1 in the central axis direction, and four blade pieces 9 are provided radially protruding from the circumferential surface of the ventilation pipe 7. They are formed in multiple stages at the same axial position in the length direction.

Further, in the ventilation pipe 7 between the blade pieces 9 in the circumferential direction, ventilation holes 10 are opened at several locations along the length direction of the blade piece 9 and biased to one side.

Furthermore, a large number of fin-shaped feed blades 11 are protruded from the inner surface of the rotary cylinder 1, and the length direction of the feed blades 11 is slightly inclined to one side with respect to the direction parallel to the axial direction, so that the entire body is They are arranged in a spiral pattern.

In addition, the blade pieces 9 are fixed to the inner ends of support arms 8 that protrude from the inner surface of the rotating cylinder 1 toward the axis at appropriate intervals, and the ventilation pipes 7
is supported.

The support arm 8 has one end fixed to a protrusion 24 protruding from the inner surface of the rotary cylinder 1, and protrudes from the protrusion 24 in a slightly inclined direction that is substantially on the same plane as the blade piece 9 and not orthogonal to the axial direction. The tip is fixed to the blade piece 9 so that the inclination direction is opposite to that of the adjacent support arm 8.

Further, in the middle of the support arm 8, a reversing plate 25 in the form of an elongated plate is fixed on substantially the same plane as the blade piece 9 and inserted over substantially the entire length of the rotary cylinder body 1.

Further, reference numerals 12 and 13 are fixed cover plates that are in contact with the openings at both ends of the rotary cylinder body 1, and these fixed cover plates 12 and 13 are fixedly supported by rising frames 14 and 15 that are raised from the frame 2. Flanges 16 attached to both ends of the rotating cylinder 1.
It is inserted in 17.

Further, one end of a ventilation pipe 7 inserted into the rotary cylinder 1 is rotatably protruded from the center of one cover plate 12, and a blower pipe 18 connected to a blower is rotatably connected to the ventilation pipe 7.

Furthermore, a hopper 19 and an exhaust pipe 20 are attached to the cover plate 12, which communicate with the inside of the rotary cylinder 1.

A discharge port 21 is opened in the other cover plate 13, and an opening/closing plate 22 is attached to the outer surface of this discharge opening 21.
2 is connected to a screw punch 23 attached to the cover plate 13 so as to be able to move up and down, so that it can be opened and closed.

Next, the operation of the above embodiment will be explained.

The rotating cylinder 1 is rotated on the rollers 3 via the sprocket gear 5 by driving the electric motor 6.

Fermented materials such as fertilizers and feed (approximately 80% water content) are supplied from a hopper 19 into the rotating cylinder 1, and at the same time, compressed air supplied from the blast pipe 18 to the ventilation pipe 7 is blown out from the vent hole 10 and comes into contact with the fermented material. This is then subjected to oxidative fermentation.

As the rotary cylinder 1 rotates, the ventilation pipe 7, blade piece 9, and reversing plate 25 also rotate simultaneously, and the material to be fermented is stirred by the blade piece 9 and is arranged in a spiral while coming into contact with the air blown out from the ventilation hole 10. The rotary cylinder body 1 is moved forward by the blade pieces 9.

At this time, even if the space inside the rotary cylinder 1 is filled with about 80% of the material to be fermented, the material to be fermented descends in one layer on the lower surface side of the blade piece 9, creating a space a.
A sufficient amount of air is blown out from the vent hole 10 located on the lower side, dispersed in the space a, and blown into the material to be fermented.

Further, the material to be fermented that is filled in the rotary cylinder 1 outside the rotational position of the blade piece 9 is scooped up and reversed by the reversing plate 25 inserted between the blade piece 9 and the rotary cylinder 1. This prevents the material to be fermented from being locally rotated and clumped into balls.

The air that has passed through the material to be fermented is exhausted through the exhaust pipe 20.

In addition, fin-shaped feeding blades 11 are formed on the inner circumference of the rotating cylinder 1.
This prevents the material to be fermented from slipping on the inner periphery of the rotating cylinder 1, and since it is not parallel to the axial direction but is inclined to one side and arranged in a spiral shape as a whole, it prevents the material to be fermented from slipping forward. It acts to send out.

In this way, the material to be fermented that has sufficiently come into contact with air is gradually sent forward, so the front opening/closing plate 22 is pulled up, the discharge port 21 is opened, and the material is discharged onto the belt conveyor waiting below. and sent out.

According to the present invention, a ventilation pipe with a large number of ventilation holes opened in the direction of the central axis of a hollow rotating cylinder is fixed, and a large number of blade pieces are protruded from this ventilation pipe radially and in multiple stages in the length direction. As the rotary cylinder rotates, the material to be fermented is dispersed by a large number of blades as it rotates, so approximately 80% of the space of the rotary cylinder is occupied.
Even when the material to be fermented is filled to a certain extent, there is no fear that the material to be fermented will form lumps, and a large amount of material to be fermented can be processed at once.

Furthermore, since a space is created below the ventilation hole located on the lower surface side of the blade piece, the air from the ventilation hole is dispersed and absorbed into the fermentation material through this space, which increases the effect of contact with the air. I can do it.

Also, since the cylinder body to which the ventilation pipe is fixed is rotated instead of rotating the ventilation pipe provided with the blade pieces, the rotational force is small even though it is filled with a large amount of heavy objects, thus saving power. I can do it.

In addition, since the ventilation pipe is supported by a large number of support arms protruding from the rotary cylinder through blade pieces, even if the pipe is relatively thin, a large amount of fermented material filled in the rotary cylinder can be absorbed during rotation. It does not move or deform due to material resistance.

Furthermore, since a reversing plate was inserted into the gap between the rotary cylinder and the tip of the blade along approximately the entire length of the rotary cylinder in the axial direction and fixed to the support arm, the blades were not stirred as the rotary cylinder rotated. By scooping up and inverting the material to be fermented that is out of reach by the reversing plate, it is possible to prevent the material to be fermented from locally rotating within the rotary cylinder and form lumps, allowing fermentation to proceed homogeneously. I can do it.
