[0002]

2. Description of the Related Art Conventionally, organic fertilizers and methods for producing the same are roughly divided into straws and manures.
A basic thing called stacking fertilizer that matures a fully-ripened compost by adding a chisso component, a fermenting agent, etc. is known (for example, “How to make and use organic fertilizer” published by the Agricultural and Fisheries Village Cultural Association,
55-97).

In addition, recently, research is being conducted to ripen organic waste such as domestic garbage, food residues, livestock excrement and the like into organic fertilizer. For example, organic wastes such as fish ara, sludge, leftover rice, and okara are adjusted to a water content of about 60%, fermented at about 60 ° C, and finally dried to a water content of 15% for the entire process. An organic fertilizer is produced in 48 hours, and by using actinomycetes, which are agriculturally useful microorganisms, pathogens and pests are sterilized and killed in the high temperature fermentation process of organic substances, and dried okara or Fermentation treatment equipment for organic waste has been developed that uses cost-reducing bacteria that have been treated by mixing actinomycetes with okara, and uses hot water as a heat source to achieve cost reduction and complete automation (for example, monthly waste. , Nikkan Co., Ltd., December 1993 issue, page 21, middle section).

As a method for treating food waste mainly by heating and drying, the temperature is first raised by heating the boiler to decompose the food waste, and in the presence of oxygen, the spoilage bacteria (natural Bacteria attached to organic matter) are proliferated and decomposition is promoted by aerobic fermentation, and stirring is performed with special blades.
It utilizes a structure in which it is sterilized and dried after being decomposed with a heat chelate, and raw garbage becomes an uncle or state, followed by gradual drying to a porridge-like or dough-like state, and after about 10 hours it contains water. A method is known for obtaining a soil-conditioning material in a free-flowing sand state without adjusting the rate or adding fermenting bacteria (for example, monthly waste, Nikkan Inc., December 1993, p.23, middle and lower tiers). .

Further, as a domestic garbage erasing machine, a wood strip, which is a simple substance of microorganisms, is put in a decomposition tank in advance, and the temperature is kept at 25 to 4 in order to keep the activity of biotechnology constant.
Keeping an appropriate temperature of 0 ° C, keeping the temperature and humidity, and supplying oxygen to maintain the optimal conditions for growing microorganisms, the agitating blade with multiple blades on the rotating shaft is rotated forward and backward to mix raw garbage.
A device is known that is crushed and mixed into wood chips and naturally decomposed by bioactivity without composting (for example, monthly waste, daily report issued by Inc., 19
December 93 issue, page 26, upper and middle sections).

[0006]

SUMMARY OF THE INVENTION In the above-mentioned conventional method for manufacturing manure, even if quick-compost is used, the cut-back after loading is 2 times.
It takes 7 weeks to complete the process once and it is completed, and there is a problem that the handling method is restricted because the transportation work after completion is matured. In addition, organic waste that has been developed recently In the fermentation treatment equipment, since high temperature fermentation treatment is performed while warming with warm water using actinomycetes, which is an agriculturally useful microorganism, while adjusting the water content, it takes 48 hours for the entire process even though it is fully automated. However, there is a problem that a heat source such as electric heat is required.

[0007] In addition, in the method for adjusting the water content and for promoting the decomposition of the spoilage bacteria adhering to the garbage by heating without utilizing the fermenting bacteria to accelerate the decomposition and obtain a soil conditioner, about 10 treatments are required.
There is a problem that it takes time and heating must be equipped with a large-scale boiler.

[0008] Furthermore, in the domestic garbage erasing machine, in order to decompose and eliminate the garbage by microorganisms, a wood strip is put into a hotbed of bio, and the oxygen and temperature required for bioactivity are controlled by the controller from 25 to 25. Not only a heating device is required for the treatment while maintaining an appropriate temperature of 45 ° C., but it also takes a long time to disappear, and there is a problem that it cannot be used as an organic fertilizer.

The present invention has been made in consideration of the above circumstances, and it takes a long period of time to utilize the action of fermenting bacteria to produce an organic fertilizer from an organic waste, and further, the fermentation is performed. It is a solution to the conventional problem that a heat source such as a boiler and a management system are required for the treatment, and it does not require heat source management such as a boiler or fermentative bacteria at all and requires only a few minutes for fertilizer or soil. It is an object of the present invention to provide a method for pressurizing and crushing a fibrous organic waste and an apparatus therefor capable of producing an improved material.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a pressurizing / crushing apparatus used for pressurizing / crushing processing of the present invention will be described below with reference to the drawings. Overall Configuration of Pressurization / Crushing Treatment Device In FIG. 1, the pressure / crushing treatment device 1 has a built-in extrusion screw (rotating screw), and the drive source of the extrusion screw is from the drive unit 3 via the rotary shaft 2. To be given.

A cylindrical plate (cap member) 18 having a discharge hole 17 is attached to the front end of the cylindrical casing 5, and a fibrous organic waste material is attached to the rear end of the casing 1.
A supply hopper (supply unit) 6 for supplying the inside is provided. Each of these elements is mounted on the base 4.

An endless belt conveyor 7 is arranged on one side above the opening of the supply hopper 6, and an input hopper 8 is provided on the conveyor 7, whereby a fiber material which does not need to be shredded. Organic waste supply department 9
Is configured. The input hopper 8 and the supply hopper 6 do not necessarily have to be configured separately, and when they are integrated, the belt conveyor 7 can be omitted.

On the other side of the opening, a supply swash plate 10 and a cutter 11 communicating with the supply swash plate 10 are provided.
For cutting and introducing the fibrous organic waste, which has one end connected with the cutter 11 and the other end curved with the feed pipe 12 extending above the opening of the supply hopper 6. Introducing section (cutter device) 13 is arranged.

The configuration of each unit will be described in detail below. On the inner peripheral surface of the casing 5, prismatic liners 15, 15 having one corner portion 14 of the inner surface formed at an acute angle are screwed in the longitudinal direction of the casing 5 at eight circumferentially equally positions ( Figure 3
(See), and the extrusion screw 16 is disposed on the center side thereof. In this case, a groove is formed between the liners 15.

At the tip of the casing 5, there is attached a squeezing plate 18 having a large number of discharge holes 17, and the outermost peripheral side of the discharge holes 17 has a piercing position, as shown in FIG. Is located near the outer circumference of the rotation chamber R for rotating the. Therefore, the inner diameter D of the rotation chamber R is formed to be larger than the inner diameter d of the casing 5. The blade 19 is axially attached to the rotary shaft 2 of the extrusion screw 16 so as to rotate in sliding contact with the inner surface of the sliding plate 18, so that the object to be processed can be smoothly discharged without clogging. There is. Also, at the time of sliding contact rotation,
The object that has not been crushed between the liner 15 and the extrusion screw 16 can be further crushed, or the fibers of the object can be loosened and discharged.

A gap is provided between the tip of the screw blade of the extrusion screw 16 and the sliding plate 18.
A resistance rod (rod-shaped member) for preventing rotation is provided so as to project from the inner wall of the casing 5 to the void portion. The resistance rod 20 penetrates the casing 5 and pushes out the screw 1.
6 is deeply screwed into the rotary shaft.

Usually, when a fibrous material to be treated is treated with this type of screw, the material to be treated is not loosened into individual fibers, but becomes a lump in which many fibers are entangled. ing. And the lump is the extrusion screw 1
Attempt to keep rotating with the rotational movement of 6. On the other hand, since the discharge hole 17 is bored along the axial direction of the casing 5, if the object to be processed has a large velocity component in the rotation direction as described above, the discharge hole 17 may pass through the discharge hole 17. If this is not possible, there is the inconvenience of rotating the contact plate 18 in contact with the inner wall thereof. Such a phenomenon causes the clogging of the discharge hole 17. Therefore, if the rotation speed of the extrusion screw 16 is slowed down, the speed component in the rotational direction of the object to be processed may be reduced, but in this method, the force for pushing the object to be processed from the discharge hole 17 also decreases proportionally. Therefore, it is still impossible to eliminate the clogging.

On the other hand, in this embodiment, toward the gap formed between the blade 18 and the tip of the screw blade,
Since a plurality of resistance rods 20 are provided so as to project, clogging of the discharge holes 17 is prevented, and stable and continuous pressurization / crushing processing is realized.

That is, in FIG. 2, if there is no resistance in front of the screw blade of the extrusion screw 16, the object to be processed reaches the squeeze plate 18 while maintaining the velocity component in the rotation direction. When such an object to be processed contains a large amount of long fibers, the rotational movement of the object to be processed becomes an obstacle when the object to be processed passes through the discharge holes 17 of the girder plate 18, resulting in clogging. Is likely to occur. Therefore, by disposing a plurality of resistance rods 20 that act as resistance against the rotational movement of the object to be processed in the circumferential direction of the casing 5, it is possible to eliminate clogging.

Since the resistance rod 20 is screwed into the casing 5, the amount of penetration can be changed in the diameter direction of the casing 5, and the degree of resistance can be adjusted. Therefore, according to such a configuration, an optimum resistance can be given according to the type of the object to be treated and the degree of drying.

A water supply valve (water supply section) is provided near the tip of the casing 5. The water supply valve 21 is formed in the shape of a needle valve, and a water pipe 22 that communicates with the outside is provided in communication with the side surface of the needle valve body, and the needle valve 23 is screwed into the inside. The tip end side of the needle valve 23 is arranged so as to face the above-mentioned space, and when the needle valve 23 is rotated to advance and retreat, the amount of water supplied into the casing 5 can be adjusted. There is.

The resistance rod 20 is, as shown in FIG.
Are arranged opposite to each other in the diametrical direction of the casing 5,
Further, the hydration valve 21 is arranged so as to face the resistance rods 20 at an angle in the circumferential direction.

Constitution of hydration valve Water is normally supplied for the purpose of smoothly feeding the object to be treated. However, according to the experiments on the treatment of weeds, weeds that propagate from summer to autumn (seta kawadachi, wormwood, litter, etc.) contain an appropriate amount of water, so they can be pressurized without supplementing with water. -It was found possible to operate the crushing treatment device.

On the other hand, it has been found that the weeds that grow in spring or the weeds on the waterside have an excessive water content, and it is necessary to add paper cotton or pellets made of paper cotton to absorb water. For the above reasons, in this embodiment, the water supply is not always performed, and the water supply and the water stop can be controlled. Further, when the water is stopped, the object to be treated does not enter the water supply opening and the piping system.

The needle valve 23a of the present embodiment has a conical tip, so that the thickness of the deposit adhered to the water supply opening is reduced. Thereby,
The deposits are easily removed during water supply.

The mounting position of the water supply valve 21 is arranged within a range of 3 pitches from the tip of the screw blade, that is, a portion where the object to be treated is pressurized on the tip side of the casing 5 by the feeding action of the pushing screw 16. ing.

More specifically, in the vicinity of the feed hopper 6 in the casing 5, the object to be processed is conveyed in the axial direction of the casing 5 while making a spiral motion as the extrusion screw 16 rotates. On the other hand, no compressive force is applied. Thereafter, pressure is applied as the object to be processed further moves in the axial direction.

When treating an object having a low water content such as paper cotton and rice husk, water may be added to avoid clogging. However, in the method of injecting water from the supply hopper or the method of injecting water from the casing portion in the vicinity of the supply hopper, compression by the extrusion screw starts before the material to be treated and water are sufficiently kneaded, and the compression Due to the action, the added water will be squeezed out. Therefore, since the pressurizing portion is not formed in the vicinity of the supply hopper, the mounting position of the water supply valve 21 is not appropriate.

On the other hand, according to the structure of this embodiment in which the water supply valve 21 is arranged within 3 pitches from the tip of the screw blade, the screw length from the water supply position is short, so that the fluidity of the object to be treated is enhanced. As a result, the pressure rise is suppressed, whereby the supplied water is not squeezed out of the object to be treated, and the clogging in the discharge hole 17 can be eliminated.

The number of the water supply valves 21 is not limited to the above embodiment, but may be two or more. By arranging a large number as described above, it is possible to deal with the case where the blade diameter of the extrusion screw 16 is enlarged and the water supply amount is increased for the purpose of improving the processing capacity. Further, in this case, since water can be supplied from a plurality of locations, the kneading effect is enhanced.

Further, in this embodiment, the object to be treated in the casing 5 can be discharged by rotating the pushing screw 16 in the reverse direction. Specifically, when clogging occurs, the extrusion screw 16 is usually rotated in the reverse direction. However, although the object to be processed between the screw blades can be fed backward to the position of the supply hopper 6, the screw tip and the sliding plate 18
The object to be processed in the space between and cannot be fed backward, and is left as a hard lump. However, if the hydration valve 21 is arranged at the position shown in FIG. 2, the hard lump is softened by the water supply, and if the extrusion screw 16 is normally rotated again after the lump is softened, the object to be treated stayed in the void portion. Can be smoothly discharged from the discharge hole 17. Therefore, the clogging can be eliminated without disassembling the device.

Structure of the sliding plate and the casing The sliding plate 18 of this embodiment has a plurality of discharge holes 17 formed outside the inner diameter d of the casing 5. Therefore, according to this structure, a sufficient discharge path is secured even for the object to be processed that has been conveyed along the inner wall surface of the casing 5, and the flow of the object to be processed on the tip side of the extrusion screw 16 is ensured. Becomes smooth, and as a result, clogging is less likely to occur.

The liners attached to the casing 5 are linearly or spirally formed at eight equal intervals along the axial direction of the casing 5, and the inner surface of each liner 15 is arranged in the rotational direction of the extrusion screw 16. It is formed in an inclined surface so that the height thereof decreases. The number of liners is not limited to eight, and may be appropriately selected according to the diameter of the extrusion screw 16.

According to the above-mentioned structure of the casing, the object to be treated is sandwiched between the outer peripheral edge of the screw blade and the liner 15 by the forward rotation of the extrusion screw 16 and is broken as if it is torn, so that it is ruptured softly. . Further, the corner portion 14 of the liner 15 is formed at an acute angle so that the tearing effect is increased. Furthermore, since the inclined surface of the liner 15 has a gap between the outer peripheral edge of the screw blade of the extrusion screw 16 and the end widened, the frictional force does not increase with respect to the object sandwiched in the gap, and the processing device can be operated with a small power. I am able to drive.

When the extrusion screw 16 is rotated in the reverse direction and the liner 15 approaches the outer peripheral edge of the screw blade, the distance between the corner portion 14 and the outer peripheral edge of the screw blade is large, so that the object to be processed is not torn and is screwed. It moves between the blades and is returned to the supply hopper 6 side by the reverse rotation of the extrusion screw 16. Therefore, the load does not become large during reverse rotation, and large power is not required.

The liner described above is fixed with screws so that it can be replaced. The purpose of making the liner replaceable is to deal with the abrasion of the edge of the liner corner being remarkable when handling a hard object such as rice husk or pruning branch.

Conventionally, rice husks have been incinerated in the open state for about 3 days, but since environmental problems have been taken up, it has become impossible to freely incinerate the rice husks. Has become a problem. The rice husk itself is 1
If it can be crushed to less than / 3, it can be mixed with cattle feed to be used as a digestive agent, and it can be spread in the fields. And the decomposition time in the soil becomes shorter. Furthermore, when rice husks are swelled and broken, composting becomes possible. However, in the apparatus for treating rice husks, since the main parts are easily worn as described above, a widely used processing apparatus cannot be found.

On the other hand, with regard to the pruned branches, orchards, parks,
Street trees are pruned every year, and the pruned branches are either piled up waiting for decay, incinerated, or buried in the soil. It is difficult to treat such pruned branches as well as rice husks. Pruned branches can be made into fertilizer in a short time if they are broken by softening,
Since it is harder than weeds and wear of treated parts is remarkable, measures against wear are required. When such a hard material is treated, the outer peripheral edge of the screw blade and the liner 15 are each abraded, and the softening / fracturing effect is gradually reduced.
The replaceable liner of this embodiment can eliminate such inconvenience.

[0047] The wear of the structural screw blade of the screw, and a connecting structure by combining an extrusion screw, if a configurable replaceable screw blade on the distal end side can be always maintained constant膨軟depletion potential. It is preferable that the tip side screw is made of a material having excellent wear resistance and the base side screw is made of an inexpensive material.

5 and 6 show the structure of the split screw. First, referring to FIG.
Is composed of a tip side screw 16b and a base side screw 16c connected to the tip side screw 16b, and a blade tail of the tip side screw 16b and a blade head of the base side screw 16c are screwed when both are connected. The phases are matched. Therefore, a box-shaped protrusion 16d is formed on the connecting side shaft portion of the tip side screw 16b, while a box-shaped hole 16e capable of engaging with the protrusion 16d is formed on the connecting side of the base side screw 16c. Has been done.

FIG. 6 shows a modification of FIG.
In the figure, the tip side screw 16f is a through hole 16g.
And a projection 16 having a square edge at its connecting portion.
h is projected. On the other hand, the base side screw 16i has a through hole 16j that is coaxial with the through hole 16g, and a square hole 16k that can be engaged with the protrusion 16h is formed in the connecting portion thereof. And connect both, through-hole 16g, 1
The screw 16 is completed by inserting the shaft 75 into 6j. The keyway and the like are omitted.
If the tip portion of the screw is replaceable as described above, the expansion / softening fracture ability can be constantly maintained. The extrusion screw 16 of the present invention has a pitch that becomes closer to the tip side, and the compression ratio is selected according to the object to be treated.

Next, a method for producing an organic raw fertilizer using the pressurizing / crushing apparatus having the above-mentioned structure will be described.
One supply swash plate 10 of the pressurizing / crushing processing apparatus shown in FIG.
When more fibrous organic waste, for example, pruning branches such as bamboo are supplied, the pruning branches are cut into short pieces in advance by the cutter device 11 and are supplied from the supply hopper 6 to the pressurization / crushing processing device via the feeding pipe 12. It For fibrous organic waste that does not need to be cut, such as rice husk, directly
It is supplied from a supply hopper (supply unit) 6.

The object to be treated supplied to the pressurizing / crushing apparatus is fitted into the spiral groove of the screw blade and is conveyed toward the front end of the casing 5 while rotating spirally. At this time, the outer peripheral edge of the screw blade and the liner 15
The object to be processed advances while being sheared and crushed by the corners 14 and is further pressed and kneaded by the propelling force of the extrusion screw 16. At this time, the temperature of the object to be treated in the casing rises to about 80 to 90 ° C. At this time, the object to be treated is subjected to high pressure and high temperature and frictional action to destroy the cell shell, and the pest or its egg and the weed seed are killed.

Next, the object to be processed sent to the sliding plate 18 side by the propulsive force of the extrusion screw 16 is stopped by the resistance rod 20 from rotating, and further propulsive force acts in that state, whereby the discharge hole 17 More discharged. In this case, it is preferable to operate the water replenishment valve 21 to replenish water especially when the object to be processed is extremely dry.

As described above, the material to be treated is the fibrous material 1.
When it is 00%, it is discharged in a state of being loosened into fine fibrous form, so it has good air permeability, water absorption and water retention, is easily decomposed, and is easily compatible with soil. Therefore, it can be used, for example, as a soil improving material.

When the present invention is applied to the agricultural field,
Not only can organic raw fertilizers be produced, but also compost raw materials can be produced. For example, taking a pruned branch as an example, the fermentation time is 1/2 to 1/3 of that of the conventional method when the puffing treatment according to the present invention is performed in contrast to the usual compost manufacturing method of cutting with a chipper. Can be shortened to Even if the object to be treated is a hard tree branch, if the swelling / softening treatment according to the present invention is performed, the fiber structure of the branch is destroyed and becomes soft, thereby increasing air permeability. Therefore, an anaerobic spoilage bacterium does not grow, and a corrosive organic substance that is spoiled by an aerobic bacterium is obtained, so that a raw material suitable for compost can be obtained. The above-mentioned compost raw materials include nitrogen, phosphoric acid,
Conventionally known fertilizer elements such as potash can be added.

Further, since the pressurizing / crushing processing apparatus shown in the above-mentioned embodiment is extremely compact, the rotary screw can drive the power of the tractor by branching, for example. Further, the groove of the present invention is formed by mounting the liner in the above embodiment, but the present invention is not limited to this, and the groove may be formed directly on the inner wall of the casing.

Further, the present invention is not limited to the treatment of the pruned branches described in the above examples, but also the treatment of vegetable waste such as rice husks, weeds and harvested waste, and the treatment of used paper such as newspapers, old magazines and cardboard. Furthermore, the present invention can be applied to pressurization and crushing treatment of waste such as food waste whose main component is fiber.

[0057]

EFFECTS OF THE INVENTION According to the present invention, the fermentation process that takes a long time, the heating device such as the boiler, etc. are not required at all, and the organic waste is used for the spoilage to stop the spoilage in the soil. It is possible to produce raw fertilizer containing a large amount of fiber, which is naturally digested when broken. According to the present invention, crushing
Since the softening treatment can be performed, the compost raw material can be easily produced in a short time even with a hard organic waste such as a pruned branch.
