DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding apparatus for molding a fibrous material containing waste paper as a main raw material into a desired extrusion shape. INDUSTRIAL APPLICABILITY The apparatus of the present invention is widely used as an apparatus for producing agricultural fertilizers such as compost, or fertilizing / fertilizing materials, nursery materials, and culture mediums for growing agricultural products such as seedling wood for cultivating mushrooms.

[0002]

2. Description of the Related Art In recent years, recycled paper has been actively used for the purpose of resource conservation, and one of the methods is attempted to be used for compost in the agricultural field. For example, a cotton-like recycled pulp obtained by defibrating used paper with a dry defibrating device is used, and (a) the recycled pulp is mixed with plants (leaves, twigs, etc.), and water is supplied to obtain an appropriate moisture content. After adjusting the rate, a method of fermenting these to produce compost (see the process diagram in FIG. 14), or (b) the recycled pulp is excessively sprayed in orchards and paddy fields to absorb the accumulated fertilizer. A method of using it as fertilizer has been proposed.

The dry defibrated cotton-like recycled pulp has the following features (advantages and disadvantages). Repels water (non-hydrophilic). Dust is generated. Specific gravity is small. The features of the dry defibration treatment as compared with the wet defibration treatment include the following points. The fiber length is short. There is a lot of paper dust. There are many undefibrated materials. No wastewater treatment equipment is required, so equipment costs can be reduced and equipment can be made compact.

These characteristics can be advantages or disadvantages depending on the application field of the above-mentioned recycled pulp. For example, when using the above-mentioned pulp as recycled paper, it is necessary to suppress the undefibrated material to 0.1% or less to make the surface of the paper uniform, which is a drawback, but it is used as compost. In this case, there is a report that the undefibrated material may improve fertilizer retention, which may be an advantage.

In the case of composting using the above-mentioned recycled pulp, due to the property of repelling water, the recycled pulp and water are separated even if water is supplied, and the recycled pulp easily absorbs water. There is a problem that it cannot be done. By performing an operation such as artificially compressing the regenerated pulp in water, it is possible to allow the regenerated pulp to absorb water, but in that case, it is not possible to uniformly adjust the water content in the produced compost. It is difficult and very time-consuming, and is not useful for industrial use.

When the recycled pulp is used as a fertilizer, for example, when it is sprayed on an orchard or the like, it is easily scattered by wind because of its small specific gravity. This not only reduces the amount of pulp acting as a fertilizer, but may cause a kind of dust pollution due to pulp dust in the entire orchard.

When recycled pulp is used as seedling wood for mushroom cultivation by breeding fungi such as shiitake cultivation, it may be a medium of pathogenic bacteria depending on the history of waste paper before recycling. . Therefore, the defibrated pulp cannot be used as it is without being sterilized.

As described above, the dry defibrated pulp has advantages (eg, and etc.) in the dry defibration process, but on the other hand, when it is used in the agricultural field, it has improved water absorption capacity, dust prevention, and sterilization treatment. There is a problem that we have to overcome problems such as the addition of.

On the other hand, from the viewpoint of the field of agricultural machinery, a device for swelling and destroying tissues (organs) such as plant fiber materials or animal fiber materials by high temperature and high pressure treatment (Japanese Patent Laid-Open No. 52-1118). Has been developed, and attempts have been made to utilize the obtained swelling / disruption product as a material for raising seedlings, feed for livestock and poultry, and the like. FIG. 15 is a vertical sectional view showing the structure of this type of device. In the figure, 151 is the main body of the device, 152 is a screw,
Reference numeral 153 is a material input port, 154 is a discharge opening, 155 is a cutter, and 156 is an enlarged diameter part. This device continuously forms a screw vane portion 157 having a constant outer diameter and a tapered screw vane portion 158 which has a diameter that gradually decreases toward the discharge portion side. By rotating the screw 152, pressure and compression are performed while the material is being transferred, and thereby the swelled and softened destructible material due to the fibrous material is taken out from the discharge opening 154.

Since the above-mentioned device has both pressure compression and heat sterilization of the fibrous material, the above problems of the cotton-like recycled pulp can be overcome to some extent, but the expansion and contraction of the fibrous tissue (organ) is to the last. -Since the material is only destroyed, it is possible to soften the material, but it is not possible to solidify the product.

When using, for example, a dry defibrated cotton-like paper as the fibrous material, since the specific gravity of the paper itself is small, when it is sprayed on the soil, it is easily scattered by wind or the like. is there. In view of preventing this and applying to fields such as agricultural machinery, it is desired that the fibrous material can be molded.

[0012]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to apply a fibrous material mainly composed of waste paper, which has hitherto been difficult to be used in the agricultural field, to pressurization. An object of the present invention is to provide a fibrous material molding apparatus that can be compressed and further solidified.

[0013]

The basic structure of the present invention is as follows.
A fibrous material whose main raw material is waste paper fed from the raw material feeding port (hereinafter sometimes simply referred to as a fibrous material) is fed to the tip of the casing by the feeding action of the rotary screw provided in the tubular casing. A device for feeding and further discharging from the tip portion, wherein a molding and discharging member that compresses the sent fibrous material and discharges it in a predetermined shape is provided at the tip portion of the casing, and the tip portion of the rotating screw. It is a fibrous material molding apparatus provided with a screw support member for rotatably supporting.

Here, the screw supporting member may be provided on the molding and discharging member. For the purpose of adjusting the feed, the rotary screw can be formed such that the screw pitch becomes smaller continuously or stepwise toward the tip of the rotary screw. Further, the depth of the screw groove can be formed continuously or stepwise toward the tip of the rotary screw. The molding / discharging member may be composed of a molding die having one or a plurality of discharging holes. The diameter of the discharge hole is preferably in the range of 10 to 40% of the diameter of the rotary screw.

A cavity may be formed at the tip of the cylindrical casing by separating the molding die from the tip of the rotary screw. Further, the tubular casing can be formed in a throttle structure in which the cross-sectional area of the casing is reduced toward the tip thereof. Further, a plurality of straight grooves or spiral grooves parallel to the rotation axis of the rotary screw can be provided on the inner surface of the tubular casing.

Further, a liquid injection means may be provided on the raw material charging port or on the barrel wall of the cylindrical casing to mix with the fibrous material. Further, a cutter that rotates coaxially with the rotating screw may be provided in the tubular casing immediately before the molding discharge member. A cutting means for further cutting the fibrous material that has been molded and discharged may be provided outside the tip of the fibrous material molding device. The above-described fibrous material forming apparatus is also suitably used for producing seedling wood for mushroom cultivation.

[0017]

When the molding apparatus of the present invention is used, the waste paper material charged into the cylindrical casing is pressed and compressed by the feeding action of the rotary screw, and then molded and discharged. Here, as the screw pitch is made smaller continuously or stepwise toward the tip of the rotary screw, or if the depth of the screw groove is formed continuously or stepwise shallow, the water content of the molding discharge is reduced. The content can be made more uniform. In the device of the present invention, since the front of the rotary screw shaft is pivotally supported, it is possible to stably feed, compress, and discharge the waste paper material. Further, by further providing a cutting means on the outside of the molding device, it is possible to positively arrange the molding discharge product to an appropriate length. For example, it is useful in forming pellets and the like.

The apparatus for molding a fibrous material according to the present invention is used for producing fertilizing / fertilizing pellets (Japanese Patent Application No. 5-338701) and compost (Japanese Patent Application No. 5-313826 and Japanese Patent Application No. 5-138138). However, as a result of further studies, the present inventors have found that the above-mentioned device is also suitably used for producing seedling wood for mushroom cultivation. Of.

Hereinafter, the present invention will be described in detail based on examples, but the present invention is not limited thereto, and any modification or implementation is possible within the scope not departing from the gist of the above and the following. It is included in the technical scope.

[0020]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 13 below, (A) shows a left side view of the molding apparatus, and (B) shows a front view of the molding apparatus.

FIG. 1 is a diagram showing the basic construction of a fibrous material molding apparatus of the present invention. The configuration shown in the figure is such that the fibrous material charged from the raw material charging port 1 is fed by the equal pitch rotary screw 3 in the cylindrical casing 2 to cause the cylindrical casing 2 to move.
A device for discharging the fibrous material sent to the distal end of the tubular casing 2 and compressing the sent fibrous material to discharge the fibrous material into a predetermined shape. A screw support member 6 that rotatably supports the tip of the equal pitch rotary screw 3 on the molding discharge member 6.
a is provided.

The molding and discharging member 6 is composed of a molding die in which a plurality of discharging holes 5 are arranged in a circular shape. Reference numeral 4 denotes a drive shaft connected to the rear shaft of the rotary screw 3, and the rear shaft is supported by a bearing 7. In this device, the screw support member 6a is provided on the molding and discharging member 6, but the invention is not limited to this. Next, the operation of the apparatus having the above configuration will be described.

First, a fibrous material containing waste paper as a main raw material is fed from the raw material feeding port 1. Examples of used waste paper materials include waste paper materials such as newspapers, telephone directories, magazines, and OA papers, which have hitherto been difficult to press and compress / mold. The waste paper may be molded alone, but if necessary, other fibrous materials may be used together. Examples of such fibrous materials include sawdust, bagasse, tree hulls,
Examples include plant fiber materials such as wood chips, chaff, litter, litter, pruned branches, and straw; animal fiber materials such as wool debris, hair, feathers, and leather debris.

When these fibrous materials are put into the apparatus of the present invention, it is preferable that the fibrous materials be made into pieces in advance. For example, when throwing in waste paper, the waste paper that has been cut into strips in advance with a shredder is fed to a dry defibration machine and defibrated into cotton (hereinafter, the defibration of dry defibrated cotton is used as a cotton swab). However, the cutting machine is not limited to a shredder. For example, used paper may be cut by hand, or may be directly put into the defibrating machine without cutting. Examples of the dry defibrating machine used include the dry defibrating apparatus described in Japanese Patent Application No. 5-265895.

The above-mentioned paper cotton originally has a property useful for fertilization, that is, it has abundant fibers, is excellent in water absorption and air permeability, and has very high water retention ability, heat retention ability, fertilization ability and fertilization ability. Due to its properties, paper cotton that has been pressure-compressed and then molded can be a very good agricultural material.

Further, the fibrous material charged into the apparatus of the present invention needs to contain an appropriate amount of water in order to smoothly carry out the pressure compression treatment. For example, among the above fibrous materials, for those already containing water in the material itself, it is not necessary to newly supply water, but when introducing a material that does not contain water, such as paper cotton, It is necessary to supply an appropriate amount of water. Further, the type of the fibrous material put into the device of the present invention varies depending on the use of the obtained molded discharge, for example, when the molded discharge is used as a fertilizer or a nursery, a seedling wood for mushroom cultivation, etc. It is also possible to supply only paper cotton and water, but when the molding discharge is used as fertilizer or compost, it is desirable to add the above-mentioned plant fiber material or animal fiber material at the same time, and Fertilizers and the like may be added for the purpose of further enhancing the fertilizing effect.

The fibrous material charged into the raw material charging port 1 is sent to the tip of the cylindrical casing by the feeding action of the equal pitch rotary screw 3 in the cylindrical casing 2 and is compressed under pressure, and then discharged into the discharge hole. 5 is formed and discharged into a predetermined shape.

More specifically, the fibrous material first enters the space between the cylindrical casing 2 and the equal pitch rotary screw 3. When the equal-pitch rotating screw has a spiral shape in the right-hand screw direction, when the screw is rotated counterclockwise when viewed from the tip side of the tubular casing, the introduced fibrous material is tubular casing. Gradually move toward the tip of. When the fibrous material reaches the tip of the cylindrical casing, a part of the fibrous material is discharged to the outside of the apparatus through the discharge hole 5 formed in the molding die. However, since the diameter of the discharge hole as shown in the figure is generally small from the viewpoint of forming back pressure, and therefore the flow resistance is large, most of the fibrous material is successively conveyed by the feeding action of the equal pitch rotary screw 3. Under the axial transfer pressure of the fibrous material, as a result, a strong compressive action is exerted on the entire material, and water is forced to permeate between the fibers in the fibrous material.
For example, when paper cotton and a vegetable fiber material are put into the device of the present invention, the tissue of the plant is destroyed during pressure compression, and a large amount of water contained in the plant is absorbed by the paper cotton, resulting in a fibrous material. Make the overall moisture content uniform. At that time, a part of the pressure energy becomes heat energy to heat the fibrous material.

The fibrous material having a uniform moisture content after being subjected to such high-pressure and high-temperature treatment is discharged from the discharge hole 5, and at that time, the fibrous material exerts a very strong compressive force as described above. Upon receipt, solidification proceeds. Therefore, the fibrous material discharged from the discharge hole 5 is molded into a solid material having a cross-sectional shape substantially equal to the shape of the discharge hole 5. Alternatively, depending on the kind of the fibrous material loaded into the device of the present invention, it may be broken into pellets by its own weight when it is discharged from the discharge holes 5.

Further, in the pressurizing and compressing step, since a very large force acts on the screw shaft, vibration and the like may occur, but the molding and discharging member 6 is provided at the tip of the cylindrical casing 2 and Equal pitch rotary screw 3
Support member 6a for rotatably supporting the tip of the screw
Since such a structure is provided, it is possible to obtain effects such that molding and discharging can be stably performed, the rotation speed of the screw can be increased, and the throughput of the fibrous material can be increased.

The fibrous material thus molded and discharged has a uniform water content, and the fibrous material can be sterilized and disinfected by the heat generated during the pressure and compression treatment. Further, when paper cotton is used as the fibrous material, it is needless to say that the effect of not generating dust due to the paper cotton can be obtained because the water is sufficiently absorbed in the paper cotton.

Therefore, by using the apparatus having the structure as shown in FIG. 1, there has been a problem when the conventional dry defibrated pulp is used for compost etc. It was possible to solve "additional processing".

The apparatus shown in FIG. 2 is provided with a rotary screw whose screw pitch is continuously or gradually reduced toward the tip of the rotary screw for the purpose of adjusting the feed rate of the screw.

In this apparatus, an unequal pitch rotary screw 8 whose pitch becomes smaller toward the tip is used instead of the equal pitch rotary screw 3 of FIG. 1, so that it becomes closer to the fiber material conveying direction. The space per pitch formed between the screw and the tubular casing becomes smaller, and the feed rate of the rotary screw decreases. As a result, the fibrous material compresses slowly.
By receiving the heating action, it is possible to make the water content of the molded discharge uniform over a sufficient period of time. The device having the above configuration is particularly useful when a vegetable fiber material is used.

The apparatus shown in FIG. 3 has a nonuniform uniform pitch rotary screw 13 in which the depth of the screw groove is formed continuously or stepwise shallower toward the tip of the rotary screw for the purpose of adjusting the screw feed rate. (The screw grooves are non-uniform in depth, and the screw pitches are equidistant).

When the depth of the screw groove gradually decreases,
The space per pitch formed between the screw and the tubular casing becomes smaller, and the paper cotton receives a slow pressurization / heating action, and the water is gradually absorbed by the paper cotton. Since the compression action works slowly in this way, the water content of the molding discharge can be made more uniform than in the case of using an equal pitch rotary screw.

The apparatus shown in FIG. 4 is provided with a cutter 9 which rotates coaxially with the unequal pitch rotating screw 8 in the cylindrical casing and immediately before the forming die. In the figure, (C)
FIG. 4 is an explanatory view showing the shape of a cutter.

Pruning branches, leaves with branches, as fibrous material,
When a tree bark or the like is used, the material itself is so hard that it may not be possible to sufficiently destroy the internal organs of the plant only by the compression action of the rotary screw. The device having the above configuration is a very effective device when pressure-molding such a fibrous material, and by providing the cutter 9 inside the device, not to mention twigs attached to the leaves, It also becomes possible to sufficiently destroy the organs in the plant (for example, petiole, vein, etc.) to allow water to flow out. Further, if the above material is used, the discharge hole may be clogged, but if the cutter 9 is used, the twig or the like can be cut and crushed, so that the clogging can be prevented. Further, by providing the cutter 9, it is possible to arrange the molded discharge product in the form of pellets. When the molding apparatus of the present invention is used for the production of seedling wood for mushroom cultivation, it is recommended to use a cutter without using a cutter and to form a molded product to a certain extent. In the apparatus of FIG. 5, the diameter of the discharge hole 5 formed in the molding die is set to be 10 to 40 times the diameter of the unequal pitch rotary screw 8.
It is in the range of%.

By thus increasing the diameter of the discharge holes 5 and preferably the number of the discharge holes 5, the diameter of the molded discharge product can be increased. Therefore, the device having the above configuration is very useful as a device for producing seedling wood for mushroom cultivation, which requires a molded product that is long to some extent. Other reasons are that a sterilizing and disinfecting effect can be obtained, that air permeability is excellent, that the water content can be adjusted to suit the cultivation of mushrooms such as shiitake mushrooms, and the conventional The weight is much lighter than that of saplings, and the labor can be reduced. If the diameter of the discharge hole exceeds 40%, the area of the mounting portion of the molding die becomes narrow and the screw support member 6a
Installation is structurally restricted. On the other hand, if the diameter of the discharge hole is less than 10%, the diameter of the molded discharge product becomes small, which causes a problem that it is difficult to discharge the molded discharge product into a size suitable for seedling wood for mushroom cultivation.

In the apparatus shown in FIG. 6, the molding die and the tip of the rotary screw are separated from each other to form a cavity at the tip of the cylindrical casing. As shown in FIG. 6, since the tip end of the unequal pitch rotary screw 8 is cut by a plane perpendicular to the rotation axis, the tip end of the cylindrical casing (molding die).
It has a structure in which a flat surface is formed. When the cavity between the tip of the rotary screw and the molding die is narrow,
The formed flat surface is the discharge hole 5 formed in the molding die.
It acts as a cover against. Since the rotary screw pivotally supported by the molding die is constantly rotating, as a result, all the discharge holes 5 are blocked. That is, it becomes impossible to uniformly take out the molded discharge product from all the discharge holes.

By using the device having the above structure,
Since a wide cavity can be formed between the tip of the unequal pitch rotary screw 8 and the molding die, the tip of the screw does not act as a lid as described above,
The fibrous material that has reached the tip of the unequal pitch rotary screw is temporarily stored in this wide cavity, and then the molded discharge product can be uniformly discharged through the discharge hole 5 by the feeding action of the rotary screw.

FIG. 7 has a throttle structure in which the cross-sectional area of the casing is reduced toward the tip of the tubular casing. With the device having such a configuration, the resistance in the axial direction is further increased, so that the compression effect can be further enhanced, and as a result, the water content of the molded discharge can be made more uniform.

In FIG. 8, a plurality of linear grooves or spiral grooves parallel to the rotation axis of the rotary screw are provided on the inner surface of the cylindrical casing. In the figure, (1) to (3) are cross-sectional views taken along the line AA of FIG. 8, and the shape of the groove is (1) is an uneven shape, (2) is a tooth shape, and (3) is a saw shape. For example:

In the apparatus of the present invention, when there is no groove on the inner surface of the cylindrical casing 2, a large frictional resistance is generated between the fibrous material and the cylindrical casing 2 during the transportation of the fibrous material.
It is necessary to apply a large amount of power to the rotating shaft. By providing the groove on the inner surface of the tubular casing as described above, a gap is created between the material and the tubular casing, so that the resistance in the axial direction is reduced and the power can be reduced. Further, this space also acts as a resistance force in the rotating direction of the fibrous material, and brings about an effect of preventing slip. As a result, the fibrous material can be positively conveyed in the direction of the tip of the casing, and the fibrous material supplied to the raw material input port is promptly conveyed and compressed under pressure. It is possible to process quality materials.

9 and 10 show the liquid injection means provided on the raw material inlet or the body wall of the casing, respectively, and in the figures, 12 indicates a nozzle. Examples of the liquid to be injected include water or an adhesive such as starch paste. Examples of the liquid injecting means include a nozzle and the like, but the type thereof is not particularly limited.

By thus supplying water through the injection means, it is possible to improve the slippage during the transportation of the fibrous material. Further, by supplying an adhesive such as starch paste, the adhesive and the fibrous material are mixed, and the starch paste sufficiently penetrates between the materials under the compression action due to the rotation of the screw and the resistance of the molding die, As a result of the fibrous materials strongly adhering to each other, a hard molded discharge product having a cross-sectional shape close to that of the discharge hole can be obtained.

The liquid injection means can be installed on both the body wall of the raw material inlet 1 and the cylinder wall of the tubular casing 2. For example, water is supplied from the raw material inlet 1 at the same time as paper cotton. In such a case, due to the "non-hydrophilic" nature of the paper cotton itself, it repels water, making it difficult to mix these fibrous materials quickly. In consideration of the fact that the inlet becomes narrower and the amount of the fibrous material input decreases, the liquid injection means 1 is provided on the barrel wall of the tubular casing.
It is preferable to set 0. By providing the liquid injection means 10 on the body wall of the cylindrical casing 2, it is possible to obtain an effect that the paper cotton and water can be efficiently mixed without reducing the area of the raw material inlet 1.

When the apparatus having the above-mentioned structure is used, the solidification of the molding discharge is further progressed, so that the handling becomes easier and the mechanization of agricultural work can be further promoted. Further, since the fibrous materials are strongly adhered to each other due to the use of the adhesive, dust is not generated when paper cotton is used, and there is no fear of dust pollution. The apparatus of FIG. 11 is provided with two raw material inlets, and in the figure, (C) shows a plan view of the molding apparatus.

By providing a plurality of raw material feeding ports 1 in this way, the area of the material which comes into contact with the equal pitch rotary screw 3 at the time of feeding the fibrous material can be widened.
A large amount of fibrous material can be loaded into the device. Also, when two or more different materials (for example, paper cotton and pruned branches) are put into the device, it is possible to put them separately if there are multiple raw material inlets, so that work efficiency is improved. You can In the device of FIG. 12, the drive shaft has an electric motor 11
Is used. A gasoline engine or a water turbine may be used instead of the electric motor.

As described above, the device of the present invention can use a driving force which is easily utilized depending on the processing amount of the fibrous material and the installation location of the device. For example, when the input amount of the fibrous material is very small, the manual operation is sufficient, but when the input amount is large, these drive forces are used to improve the handling property of the device and the processing cost. Can be reduced.

In the apparatus shown in FIG. 13, a cutter 9 is provided as a cutting means outside the tip of the molding apparatus. By thus providing the cutter 9 on the outside of the apparatus, the fibrous material molded and discharged from the tip of the tubular casing 2 can be continuously cut and arranged into pellets. Even if the cutter 9 is not provided on the outside of the device, it may be broken into pellets by the self-weighting action of the molding discharge or by providing the cutter 9 inside the device as shown in FIG. 4, but as shown in FIG. If the cutter 9 is provided, it is possible to positively and accurately cut into pellets after molding and discharging, and a pellet having a desired length can be obtained by appropriately selecting the cutter speed. it can. Therefore, this apparatus is suitable for applications other than the production of seedling wood for mushroom cultivation, like the apparatus shown in FIG.

Alternatively, as an example of the shape of the molding discharge,
In addition to the pellets, mats, sheets, and the like can be mentioned, and these shapes can be adjusted by further connecting the molding apparatus to a mat manufacturing apparatus or a sheet manufacturing apparatus.

Although the plant material is used as the fibrous material in the above-described embodiments, the bodies of aquatic organisms (for example, the heads and tails of fish) can be included in addition to the above.

This device is particularly suitable for producing seedling wood for mushroom cultivation such as shiitake mushrooms.
