Abstract

PURPOSE:To simplify a series of operation necessary for fermentation remarkably by providing a screw conveyor in a main body of a long-sized casing, and providing also a hopper at one end, a working part and a discharging part at another end. CONSTITUTION:A raw material prepd. by adding necessary amt. of water to an org. material such as fowl droppings, foods, is charged from a hopper 4, and the raw material is transferred toward the top end part successively by the action of screw blades 6 when a screw shaft 3 is revolved by a driving motor 8. During the transfer, the raw material is kneaded by the blades 6 and contact of fine particles with air is promoted, and heat of fermentation is induced by the heat of friction caused by the kneading. When the raw material reaches the working part 12, the transportation is inhibited by a stirring member attached to the external periphery of the screw shaft 3, and kneading and shearing is prompted and the density is increased. The material is pushed out during this stage from a discharging port 20 in the discharging part 19 to obtain porous built-up products.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fermentation-assisted screw conveyor that efficiently ferments waste materials such as chicken manure, feed/fertilizer, and food.

Currently, organic raw materials such as animal feed, fertilizers, and foods that are discarded from various industries are being effectively reused as fuel by fermenting them.

The best means for inducing rapid fermentation of raw materials in which water is included in an emulsified organic substance or a similar mixing density is as follows.

(1) Carefully shear and knead the raw materials to bring the fine particles into contact with air and incorporate oxygen.

(2) During the above operation, the emulsified water content is gelled and decomposed from the organic substance, and conditions for aerobic fermentation of the organic substance are applied.

(3) Furthermore, in parallel, the raw materials heat up due to frictional heat and become a raging flame of fermentation heat.

(4) The raw materials processed above are stacked to a thickness of 70 cm or more in a shape that enables a porous stacked structure.

If the above-mentioned fermentation assisting means is adopted, fermentation can be started from heat generation within the same day even with raw materials with a moisture content of 70 to 80%, and in addition, full ripening can be achieved without the need for cutting.

However, in the past, the raw materials were usually adjusted to 30-50%, or the fermentation was assisted through several turning operations, which required a long time to complete the fermentation and required a single device. However, it has disadvantages such as the fact that it requires a lot of time and effort to process.

In view of these drawbacks, the present invention has a casing body with a hopper erected at its base, and a screw shaft with screw blades screwed around the outer periphery is inserted into the casing body, and the tip of the screw shaft is arranged according to the properties of the raw material. A fermentation auxiliary screw conveyor is provided, in which a stirring part selected as appropriate is protruded so as to be freely replaceable, and the upper part of the casing body is provided with a number of discharge ports through which the raw material is extruded into thin sheets or thin rods. An embodiment of the present invention will be described below with reference to the drawings, with the aim of solving the above drawbacks.
Consisting of a casing body 2 with a cylindrical or U-shaped cross section and a screw shaft 3 inserted into the casing body 2, a hopper 4 is erected above the base of the casing body 2, and a tip is inserted through legs 5. As I go towards the direction.”
It is supported in an inclined manner to one side.

A screw blade 6 is screwed onto the outer periphery of the screw shaft 3, and the tip of the screw shaft 3 projects outward from the casing body 2 via a bearing 7.
The rotation of the screw shaft 3 is controlled by connecting the tip of the screw shaft 3 to the drive shaft 9 of a drive motor 8 mounted on the upper end of the casing body 2 via a sprocket 10, 10a and a chain 11. ing.

Reference numeral 12 denotes a processing section provided in a predetermined range of the upper part of the casing body 2, and on the inner periphery of the casing body 2 in the processing section 12, several stirring resistance rods 13, 13a, etc. are protruded in the axial direction. It is being formed.

Further, convex stirring parts 14.14a... are removably screwed onto the outer periphery of the portion of the screw shaft 3 corresponding to the processing section 12, and these stirring parts 14.14a...
is the bolt 1 as shown in Figure 4, depending on the nature of the raw material.
5 and NAND 16, etc., and is mounted so that the height of protrusion from the screw shaft 3 can be adjusted.

In addition, the stirring parts 14.14a... are these bolts 15,
Cross section by nut 16? , Δ, opening, parallel rows of convex shapes, etc., spiral rows, etc. may be constructed by arbitrarily set uneven members.

Incidentally, the casing body 2 in the processing section 12 may have a structure that can be vertically separated via a plate flange 17, as shown in FIG. 6, to facilitate adjustment of the stirring parts 14, 14a... .

FIG. 11 shows the other invention, in which a reversing screw blade 18 is formed at the distal end portion of the screw shaft 3 in the processing section 2, and is rotated in the opposite direction to the other portions. The boundary between the reverse rotation screw blade 18 and the other normal rotation screw blade 6 may have an interrupted structure or a joint structure.

Reference numeral 19 denotes a raw material discharge section, which has a discharge port 20 formed by forming a large number of horizontal grooves, ms, round holes, etc. on the outer periphery of the casing body 2 in the processing section 12.

FIG. 9 shows another embodiment of the discharge part 19, in which an extrusion plate 21 is attached to the front end surface of the casing body 2, which has a number of discharge ports 20 such as horizontal grooves, vertical grooves, and round holes. , the raw material is transferred to the casing body 2 via the extrusion plate 21.
It is configured to be discharged from the tip.

Next, the operation of the fermentation-assisting screw conveyor according to the present invention will be explained. A raw material consisting of an organic substance emulsified or containing moisture in a similar mixed density is introduced from the popper 4, and the screw conveyor is conveyed by the operation of the drive motor 8. When the Shirt 3 is rotated, the raw materials are sequentially transferred to the tip by the action of the screw blades 60. During this time, the raw materials are kneaded by the screw blades 6, and the mixture progresses while promoting the air contact of the fine particles. The frictional heat caused by the pure water generates heat, which becomes the ignition force for the fermentation heat.

Then, the raw materials are sequentially transferred to the processing section 12.
In this case, the action of the stirring parts 14, 14a attached to the outer periphery of the screw shaft 3 obstructs stable quantitative transport by the screw blades 6, and due to this interfering action, the density of the continuously transported raw material decreases. As a result, the kneading and shearing actions are further promoted, and the generation of frictional heat is also more active, creating conditions suitable for promoting fermentation within the casing body 2.

Next, in the processing section 12, the raw material is forcibly extruded from the discharge port 20 of the discharge section 19 while being kneaded and sheared by the screw blades 6 and stirring parts 14, 14a. The raw materials are sequentially and continuously extruded in the form of thin sheets or thin rods corresponding to the shapes of 20,
This extruded raw material is deposited as a porous laminate that has a lot of contact with oxygen, and rapid fermentation takes place in this deposited state.

In short, in the present invention, a screw shaft 3 having screw blades 6 screwed on the outer periphery is inserted into a casing body 2 having a hopper 4 erected at its base, and the tip of the screw shaft 3 has a hopper 4 erected thereon. Since the stirring parts 14, ]Ja..., which are appropriately selected according to Thermal action can be applied at the same time, and the casing body 2
A large number of discharge ports 20 for extruding the raw material in the form of thin sheets or thin rods are installed through the upper part of the plate, so that the raw material that has been pre-treated for fermentation is deposited in a porous deposition structure with a large contact area with air. Therefore, the fermentation rate of the raw materials during deposition can be greatly improved.

In the invention of Biburu 2, since the tip of the screw shut 3 is formed with a reversing screw blade 18 that rotates in the opposite direction to the other parts, the kneading, shearing, and heating effects on the raw materials are made even stronger. This allows the fermentation to be effectively assisted.

Therefore, according to the present invention, it is possible to effectively provide the conditions necessary for fermentation to untreated raw materials using a single device, thereby greatly simplifying the series of operations required for fermentation compared to the conventional method. Its practical effects, such as being able to do so, are enormous.
