Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an organic fertilizer manufacturing device, and is particularly suitable for manufacturing organic fertilizer using chicken manure, pig farm waste, and other livestock manure as raw materials. Regarding equipment.

(Prior Art) Fermenting livestock manure such as chicken manure to make organic fertilizer, which is then returned to farmland, has been practiced in some areas for some time.

The above-mentioned conventional organic fertilizers are obtained by naturally fermenting livestock manure for several months.

In addition, the applicant has conducted research and elucidation of the fermentation mechanism, and has found that 1 q of organic fertilizer rich in fertilizer components can be effectively produced in a short period of time using JP-A-61-232286 and JP-A-61-232287.
I proposed it.

In these previous proposals, organic fertilizer raw materials such as chicken manure (
By adding a mixed culture containing multiple types of bacteria to the "raw material" (hereinafter referred to as "raw material"), fermentation can be carried out efficiently, and by adding inorganic materials in addition to the above mixed culture, You can get a balanced organic fertilizer.

(Problems to be Solved by the Invention) However, in producing the above-mentioned conventional organic fertilizer, especially in the conventional production method, there is a drawback that it requires a long period of several months and the equipment becomes large. Also, in the manufacturing method previously proposed by the applicant,
Although there is an advantage in that useful organic fertilizer can be obtained in a very short period of time, a more compact and simple fertilizer manufacturing device has been desired. This is because the raw material has a high moisture content, so as a pre-treatment process, the centrifugal valve iI! This is because, in addition to requiring expensive equipment such as a Bell 1-press type dewatering machine, there was no fertilizer manufacturing equipment that involved a complete process.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned problems, and includes a raw material hopper that receives livestock manure such as chicken manure, and a mixture of mixed culture bacteria with the raw material from the raw material hopper. an evaporative fermentation tank for receiving the mixed raw material from the mixing agitator, fermenting the mixed raw material, and evaporating part of the water in the mixed raw material to obtain a fertilizer raw material; , a crusher for crushing the fertilizer raw material from the evaporative fermentation tank, and a sieve for sorting the fertilizer raw material processed by the crusher with a sieve to obtain organic fertilizer. .

(Function) Since the present invention is configured as described above, the raw material received in the hopper is uniformly mixed with the mixed culture bacteria by the mixing agitator, and the odor components in the raw material are decomposed. The mixture undergoes fermentation in an evaporative fermentation tank while evaporating excess water to become an organic fertilizer raw material, and this fertilizer raw material is roughly crushed and sieved to prepare an organic fertilizer.

It is a mixed culture of at least two types of fungi selected from Achromobacter, Flavobacterium, Aerobacter, and Nitrobacter mycelia. This mixed cultured bacteria is added to water in the adjustment tank 3, adjusted to a predetermined concentration, and then added to the mixing agitator 8!2.

The mixer 2 uniformly mixes and stirs the raw materials, mixed culture bacteria, and returned fertilizer to form a raw material mixture, and quickly biologically deodorizes odor components in the raw materials using the mixed culture bacteria and returned fertilizer.

This raw material mixture is then sent to the evaporative fermentation tank 4, where it is subjected to fermentation and evaporation.

This evaporative fermentation tank 4 includes three evaporative fermentation tanks 4a.

4b and 4G, and the above-mentioned raw material mixture moves in series in these three evaporative fermentation tanks while being reversed and agitated, and is subjected to fermentation operation and water evaporation action during this movement.

Further, each of the evaporative fermentation tanks 4a, 4b, and 4c is composed of an inner cylinder and an outer cylinder, as will be described later, and the outer cylinder is heated by hot water heated by the boiler 5. Therefore, the temperature inside the evaporative fermentation tank is such that microorganisms are easily active3.
The temperature is maintained at around 5°C, and the evaporation of water is promoted by heating.

In the evaporative fermentation tank 4, the raw material mixture undergoes fermentation and evaporation to produce B.
While the OD component is decomposed, the moisture content is adjusted to become a fertilizer raw material, and this fertilizer raw material is adjusted to a uniform particle size by a crusher 6.

As this crusher 6, a known one can be used. For example, there is a crusher in which a large number of rods protrude from the inner wall of a container, and a rotary shaft with a large number of beaks installed between the rods is rotated by a rotor.

The fertilizer raw material processed by the crusher 6 has its particle size adjusted by a sieve 7. That is, particles having a predetermined size or more are received into the product hopper 7a together with the product raw materials (1) without falling through the sieve, packed in bags, etc., and shipped.

On the other hand, the powdered fertilizer is received in the return hopper 7b, from which it is returned to the mixer agitator 2 described above.

In addition, in the figure, 8 is a condenser, which condenses the water vapor generated in the evaporative fermentation tank 4, and a part of the obtained condensed water is sent to the adjustment tank 3 in order to adjust the mixed culture bacteria.
and the remainder is discharged.

In addition, 9 in the figure is a blower for blowing air to the mixer and agitator 2, which supplies the enzyme necessary for fermentation of the raw material mixture in the mixer and agitator 2, and also removes the water vapor generated in the mixer and agitator 2. It is efficiently sent to the condenser 8.

In addition, in the figure, raw material hopper 1. Mixing agitator 2, evaporative fermentation tank 4. To transfer the raw materials, mixed raw materials, or fertilizer raw materials between the crusher 68 and the sieve 7, known conveyance means such as a bell 1 to conveyor, a chain conveyor, or a screw conveyor can be used.

2 and 3 show details of the above-mentioned mixer agitator 2.

In other words, a closed box body 2 whose cross section is approximately oval in shape.
Two rotating shafts 22, 23 are provided in the longitudinal direction of the 1, and a plurality of stirring blades 24, 23 are provided on these rotating shafts 22, 23.
25 is installed by welding.

Stir these! 24 and 25 are made of rectangular plates, and one end of the short side of these plates is welded to extend radially around the rotating shaft 22°23 at predetermined intervals in the longitudinal direction of the rotating shaft. ing. Moreover, the direction of the plate material of the stirring blade in the width direction is installed at an angle other than perpendicular to the axis of each rotating shaft 22, 23, and the angle of installation is not uniform for each stirring blade 24° 25 and is random. It has become.

Furthermore, a claw 24' is provided at the tip of the stirring blade 24 provided on the rotating shaft 24 so as to be perpendicular to the plate surface of the stirring blade 24.

Note that each stirring blade 24 provided on the rotating shaft 23, 24
．． 25 is located between the rotary blades of each rotary shaft and arranged so as not to inhibit each other's rotation.

In the figure, reference numerals 26 and 27 are gears provided at each rotation @ 22 and 23, which are rotated by the prime mover 28. Note that the rotational directions of the respective rotating shafts 22 and 23 are such that they rotate outward in opposite directions, so that the motor 2
Gear 26 rotated by 8 is in communication with gear 27 via an intermediate gear (not shown).

In addition, 29 is an opening/closing lid, which is closed during mixing and stirring.
It is normally closed with bolts and can be opened for maintenance and inspection.

Further, 30a and 30b are 7 lunges, and 30a
The flange 30b is for inputting raw materials, mixed culture solution, and returned fertilizer, and the 7 lunges 30b are for discharging the mixture.

In the mixing agitator configured as described above, the raw material, mixed culture solution, and returned fertilizer introduced from the flange 30a are thoroughly mixed and agitated to form a uniform mixed raw material. In particular, since the stirring blades 24.25 are attached to the rotating shaft 22.23 at a predetermined angle, and the claw 24' is provided at the tip of one of the stirring blades 24, a part of the raw material is inside the mixing stirrer. It will not be allowed to stand still without being subjected to stirring action. Therefore, the raw material, mixed culture bacteria, and returned fertilizer are mixed uniformly, so that the odor components in the raw material are evenly decomposed, and the moisture content of the raw material is effectively adjusted.

In addition, in the illustrated mixing agitator, one of the agitating blades 24
Although an example is shown in which a claw is provided only on the stirring m25, the other stirring m25 may also be provided with a claw. However, in this case, it is necessary to take care not to interfere with the rotation of each other's rotation axes.

Generally speaking, the rotating shafts are rotated by a combination of gears, but this may also be done using a V-belt. do.

4 and 5 show details of the evaporative fermentation tank 4 described above. This evaporative fermentation tank 4 is mainly composed of an outer cylinder 41 and an inner cylinder 42.

The outer cylinder 41 has a plurality of passages 43 for hot water to pass through in the longitudinal direction of the cylinder, through which the hot water produced by the hot water boiler 5 enters from one side of the passage 43, and the hot water flows out from the other end. is piped to return to hot water boiler 5 again (
(See Figure 1).

On the other hand, the inner cylinder 42 has ring members 44 arranged at equal intervals,
A large number of rods 45 are passed through these ring members 44 to form a curtain-like body, and raking blades 46 having an arcuate cross section and having the same length as the rods are welded to the rods 45. . In addition, end plates 47a and 47b are provided at both ends of the inner cylinder 42, and gears 48a and 48b are arranged concentrically with the inner cylinder 42 roughly outward from the end plates 47a and 47b. Therefore, by rotating the gears 48a and 48b, the inner cylinder 42 can be rotated.

Note that the inner cylinder rotates in each evaporative fermentation tank 4a, 4b.

This is done by connecting one gear 48a attached to the 4G inner cylinder with a chain and driving this with a drive machine 49. Also, in order to ensure smooth rotation of the inner cylinder, the other gear 48b is connected with a chain. (See Figure 1).

Further, in the figure, 508 is an opening for introducing the mixed raw material from the above-mentioned mixing/stirring [2], and 50b is an opening for sending the evaporative and fermented fertilizer raw material to the next evaporative fermentation tank or crusher 6. It is.

Although not shown, the outer cylinder 41 is provided with an air intake port from the blower 9 and an exhaust port for sending the air containing the above to the condenser 8.

In the evaporative fermentation tank configured as described above, the opening 5
The mixed raw materials introduced from 0a are maintained at an appropriate temperature by hot water and are reversely stirred by the raking blades 46, so that enzymes can be sufficiently incorporated and the fermentation action can be carried out efficiently.

Moreover, water in the mixed raw materials can be effectively evaporated.

Although the illustrated evaporative fermentation tank 4 is composed of three evaporative fermentation tanks, the number may be one or two, or even four or more, taking into consideration the amount of raw material generated. Roughly speaking, the rotation of the evaporative fermentation tank is controlled by one drive machine 49.
Although the two cylinders 42 are rotated, it is of course possible to provide a driving machine for each evaporative fermentation tank.

FIG. 6.7 shows details of the sieve 7, and in both figures 71 is a sieve whose overall shape forms part of a cylinder. Both ends of this @71 in the longitudinal direction are supported between a support frame 72 with a low height and a support frame 73 with a high height. In addition, these support frames 72, 73
is provided with a long hole 74, into which a protrusion 75 provided on the frame 71a of 1171 is loosely fitted.

Roughly speaking, the frame 71a of the sieve 71 has the motor 7 at the other end.
One end of a link 78 is rotatably connected to a rotary eccentric disk 77 rotated by a rotary eccentric disk 77 . Therefore, the sieve 71 can be swung left and right by the rotation of the rotating eccentric disk 77 (see arrows in FIG. 7).

In addition, 79 in the figure is a guide plate provided at the bottom of the sieve 71, and the fertilizer that has passed through the mesh of the sieve 71 is transferred to the screw conveyor 8.
It is designed to guide you to 0.

Therefore, this guide plate corresponds to the return hopper 7b in FIG.

In the m machine 7 having the above configuration, the fertilizer raw material sent from the crusher 6 is f! Received above i71, 1i7
When the fertilizer raw material is moved downward by the tilting and swinging of 1, the powdered fertilizer passes through the sieve mesh during this movement and is returned to the mixing agitator 2 described above by the screw conveyor 80. On the other hand, the fertilizer that has moved downward on the sieve is packaged in bags (not shown) and shipped as an organic fertilizer product.

In the above embodiment, the raw material from the raw material hopper 1 is mixed with the mixed culture bacteria from the adjustment tank 3 in the mixing agitator 2, so that odor components in the raw material are rapidly biologically deodorized. Furthermore, by mixing the fertilizer returned from FJ machine 7, the deodorizing effect is greatly promoted, and
Moisture adjustment in the raw materials is also carried out.

The mixed raw materials processed by the mixer agitator 2 are heated in the evaporative fermentation tank 4, and are reversely agitated by the scraping blades 45 provided in the inner cylinder 42, so that water is effectively evaporated and water is removed from the air. Fermentation proceeds by consuming oxygen.

Therefore, when the treatment is completed in this evaporative fermentation tank 4, an organic fertilizer is produced which has a low moisture content and is rich in fertilizer components in which the BOD components in the raw materials have been decomposed.

However, since the fertilizer raw material obtained from this evaporative fermentation tank 4 is in a state where the particle size is uneven including lumps, it is necessary to crush it with the crusher 6 and further separate the powdered fertilizer with the @machine 7. It will be done. Therefore, the fertilizer sorted by the sieve 7 is granular, has a low moisture content, and is easy to handle.

An example of the ingredients of the fertilizer obtained using this example device is as follows: per 100 g of fertilizer, moisture is 13.3 a, nitrogen is 2°6 (1), phosphoric acid (P2O3 is >5.6 (II) and potassium (K
A product rich in fertilizer components can be obtained with a low moisture content of 2.6o (as 2O).

(Effects) In the present invention, the mixed raw material obtained by adding mixed culture bacteria to the raw material and stirring it with a mixing agitator is fermented and evaporated in an evaporative fermentation tank, and the particle size is adjusted with a rough sieve machine. With this structure, deodorization is performed during mixing and stirring, and moisture adjustment is also performed at the same time as fermentation, so there is no need for separate dehydrator or deodorizer equipment, and the particle size can be adjusted using the II machine. Because the organic fertilizer is produced in a uniform manner, a uniform organic fertilizer can be obtained. What's more, this manufacturing process has the benefit of allowing everyone to work together from the input of raw materials to the discharge of the product.
