Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and an apparatus for producing fertilizer and feed from water-containing organic waste such as livestock manure and sludge, grass for feed, fruit dregs, etc. as raw materials. In particular, the present invention relates to a manufacturing method and apparatus in which the removal of moisture, which is essential for manufacturing fertilizers, etc., is achieved by introducing a new method to the cross-fertilization configuration.

Recently, attempts have been made to produce fertilizers and feeds using water-containing organic wastes such as livestock manure and sludge, or fruit scraps as raw materials. However, in order to use these substances with a high water content as fertilizer, it is necessary to remove the water at an equal pressure.
! The cost of drying and drying fuel was inefficient, and economic efficiency was still low. That is, conventionally, raw materials were placed in a sealed casing and heated and dried from the outside while being transported, or quicklime, etc., which had a chemical exothermic effect was placed inside the casing, and with the help of these, the raw materials were heated and dried. , water was removed.

The present invention fundamentally reviews such conventional methods, introduces a new method for mixing and transferring raw materials, efficiently processes this type of water-containing organic waste, and produces low-cost fertilizer and feed. In addition to proposing a method for manufacturing , we also propose a highly efficient and compact processing device. In other words, in the present invention, some of the raw materials are pushed back during cross-wire transfer to cause active collision of the raw materials with each other, and the heat generated by this is used to eliminate the special heating and chemical reactions that were conventionally required. The present invention is designed to be able to produce fertilizers, etc. from which moisture has been removed, without using an exothermic reaction, or even if it is used, by only using it as an auxiliary agent. This will be explained in detail based on the following. First, the configuration of an apparatus for carrying out the method of the present invention will be described, and then the method of the present invention will be described together with an explanation of the operation of the apparatus.

First, reference numeral 1 designates a stirring casing which constitutes the main body of the present invention, and a charging hopper 2 is attached thereto so as to cover the upper part of the stirring casing, and the two communicate with each other at one end. That is, within the hopper 2, for example, two crushing shafts 3.3 having a large number of blades rotate in a lying position, and a scree conveyor 4.4 is provided below them so as to overlap. Furthermore, above the supply port 5 through which the stirring casing 1 and the hopper 2 communicate, a screw conveyor-like drug supply conveyor 6 is provided so as to be orthogonal to the screw conveyor 4, and the hopper is connected directly above the screw conveyor. It is divided to constitute a drug input hopper 2'. Next, the configuration inside the stirring casing 1 will be described. The stirring casing 1 has, for example, a flat or horizontal eight-shaped cross section, and a pair of transfer rotors 7 are provided in parallel therein. This transfer rotary body 7 forms a conveyor-like spiral blade 9 in a range of approximately one-third to half of the total length from the supply port 5 side with respect to the shaft 8. The range in which the spiral blades 9 are formed is defined as the pumping range. Following this helical spring 9, the shaft 8 is provided with a main wing blade 10 which is bent into a scree shape.
are formed at appropriate intervals.

Between the main feeding blades, push-back blades 11 having a smaller feeding action are provided 4. In other words, the main feeder blades are curved in the same direction as the feeder direction by the spiral blade 9 in relation to the rotating direction of the shaft 8, whereas the pushback blades 11 are curved in the opposite direction. It is formed to form a surface. Incidentally, in this embodiment, a pair of these transfer rotating bodies 7 are provided in each casing, but it is not necessarily necessary to provide a pair.
There is no problem even if it is only one. And this shaft 8 is located there *! outside the stirring casing 1! The gears 12 are configured to rotate in opposite directions to each other. Note that some illustrations of the motors and the like that drive these are omitted. Such a stirring casing has an opening on the side opposite to the supply port 5,
This is the salt 9 outlet 13. A powder processing device 14 is connected to this outlet U. 1 This powder processing device 1
4 is sufficient as long as the desired shape of the product can be obtained, and since the illustrated embodiment shows a crusher 4 that performs a crushing process as an example, the crusher 4 is connected via a belt conveyor due to the take-out and outlet ratio. It is something.

In addition, it may also be made into granules using a pelletizer.
For example, with a configuration that has the same basic configuration as a so-called meat grinder, the processed material taken out from the removal port can be scraped.
It may be pushed out by a knife and pulled out by a cutting blade having a large number of holes provided in front of the knife.

The apparatus of the present invention has the configuration described above, and its operation will be explained below.

First, raw material A is charged into hopper 2 at the start of operation. At that time, the raw material AFi is a single raw material, which is good, or when the moisture content is extremely high, in order to obtain a product with an appropriate moisture content, it is necessary to use a finished raw material, such as simply crushed dried straw, etc. There is no problem in mixing it with the beans or adding the dried beans as a return material. The raw material A thus charged into the hopper is crushed by the rotation of the rotating crushing shaft 3 provided in the hopper and dropped into the lower part of the hopper. As mentioned above, the scrim conveyor 4 is rotating below the hopper, so that the scrim conveyor sequentially collects the scrims on the supply port 5 side and mixes them above the supply port 5. The raw material A that has entered the stirring casing 1 is first force-fed toward the outlet of the stirring casing 1 by the spiral blades 9 of the transfer rotary body 7. From the point where the spiral blade 9 ends, the main feed blade lO stirs the air and feeds it forward. During this transfer, for example, when two transfer rotors are arranged side by side on the left and right as in this embodiment, they collide with each other while being transferred as shown by the arrows in Fig. 4, resulting in more active stirring. is done. In this way, at the same time as the raw material A is fed by the action of the main feeding blades 10, the raw material A is not simply moved forward, but also receives the action of the push-back blades 11 provided between the main feeding blades 100. Part of it is pushed back and repeatedly collides with the advancing raw material. However, when comparing the amount of feeding action between the main feeding blade lO and the push-back blade 11, the amount of acting on the main feeding blade 9 is greater, and since it is also being pushed out by the helical spring QK, this raw material Viewed as a whole, they proceed one after another toward the position of the outlet 13 of the stirring casing 1. In this way, the raw material does not simply move toward the outlet B, but collides with the raw material (indicated by arrow A°) that is pushed back on the way and returns to the t-map. This promotes heat generation and removes the moisture from the kana. Incidentally, if we compare this with the simple cross-wire feed of the conventional manufacturing method, the raw material is conventionally heated from 0 degrees to 80 degrees in 40 minutes from the start of operation, but as in this case, the raw material is heated from 0 degrees to 80 degrees. When added, a temperature of approximately 60 degrees to 60 degrees can be obtained by adding approximately half of that amount, t. The raw material that has reached the stop of the accumulation outlet in this way is pushed out to the belt conveyor 15 toward the powder processing device 14K by straight blades provided corresponding to the outlet. Then, the powder processing device 14' converts the powder into powder or granules as appropriate.

As described above, according to the method of the present invention, while the raw materials are being kneaded and transferred, a portion of the raw materials is pushed back so that the raw materials actively collide with each other, so that the exothermic reaction therein is extremely effective. This allows sufficient moisture to be removed.

Furthermore, in order to carry out such a method, the apparatus of the present invention includes spiral blades, main feeding blades, and
Since the push-back blades are provided, a desired material transfer form can be adopted, and sufficient stirring can be expected.
Therefore, there is no need to make the stirring casing itself large in order to prolong the reaction time, and it can be formed into a continuous structure.
