JP2010120366A - Compressed woody material formed by compression using a plurality of rollers - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To solve such a problem that importance is given to the use of a woody fuel in association with price escalation of fossil fuels to surely increase heating by woody pellets but its spread is unfavorable because the woody pellet is more expensive than expected even in consideration of requiring more labor and time such as ash disposal than the use of petroleum fuels. <P>SOLUTION: A compressed woody material 23 is produced by making the woody chip 19 in a hopper 20 pass through a woody material compression device 21. The compressed woody material has such characteristics that tangling of the woody chips with each other is prevented because fine woody fibers present on the surface of the chip lessen by compression action. Thus, the compressed woody material can be used as a litter tray for livestock or fuel. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The soaring oil created the spread of wood-based pellet stoves. However, the price of wood pellets is also higher than expected, which hinders further diffusion. The present invention has been developed for the purpose of solving these problems.

The formation of wood pellets is greatly influenced by the moisture content of the raw wood and the type (nature) of the wood. Therefore, it costs money to solve these issues, and as a result, it is reflected in the product price and becomes higher.
Woody combustion does not interfere with combustion even if there is a certain moisture content. However, in the formation of wood pellets, the pellets will not be in shape unless the moisture content is constant (15% to 17%). In other words, it is said that a lot of expenses are used to secure the shape.
The present invention aims to solve these problems from the viewpoint of wood combustion and pellet shape.
We investigated the patent literature, but there was no similar literature related to the present invention.

With the invention substance of claim 1, currently there is a problem of shortage of laid straw on the barn floor in Japanese beef production (including dairy cattle). Insufficient litter is a shortage of rice straw, because when harvesting rice, the rice straw is cut using a combine and scattered in the field. What was developed for the purpose of solving these problems is the compressed woody material 23 of claim 1, which was developed for the purpose of solving the problems by using relatively surplus wood.
Inventive substance 26 of claim 2 is aimed at further low-priced wood fuel. The spread of pellet stoves is regarded as important from the viewpoint of CO2 reduction, but here the spread figures have been sluggish. Therefore, it was developed for the purpose of promoting heating using wood as fuel by realizing even lower prices.

In relation to the livestock litter (laying straw) according to claim 1, a large amount of wood chips are introduced from the hopper of FIG. Heat is generated at the same time that the wood is destroyed by the twisting action. The generated heat evaporates moisture contained in the wood, and as a result, an effect of lowering the moisture content of the formed compressed wood material 23 can be obtained. Furthermore, as shown in Fig. 1, the wood is destroyed and simultaneously compressed from the left and right, forming a 2 mm thick rice cracker-like wood. By producing a large amount of the compressed woody material 23, a woody material that exhibits a fluffy aggregate and has the characteristics of an alternative rice straw is generated.
In the small-sized woody material 26 according to the second aspect, after the compressed woody material 23 is formed, the small-sized woody material 26 is further generated by the functions of the wood chipper devices 24 and 25. The feature of this substance is that the moisture content is reduced and the feather shape on the surface is reduced, so that the entanglement obstacle (bridge trouble) in the process of being conveyed to the combustion section is eliminated, and the smoothly flowing conveying action is obtained. .
Next, the other feature, a method for solving the problem relating to production cost in production, is that the wood fuel of the present invention is structurally simple and low-cost production compared to the production cost associated with the production of wood pellet fuel currently used. Is possible. Therefore, the production of invented wood fuel with low manufacturing costs will enable the supply of wood fuel at low prices to general consumers.

The production of low-cost wood fuel will become possible, and it is thought that the spread of wood fuel will further advance. Moreover, the effect which contributes also to elimination of a CO2 subject can be acquired by promotion of spread.

The mechanical production structure of the substance of the present invention is very simple for wood pellet manufacturing. Therefore, it seems that the best mode is to collect data by first creating a production device, performing demonstration production, and simultaneously performing a combustion test using a pellet stove.

Currently, we are conducting a verification test using the equipment shown in Fig. 2 for the verification test and the wooden chippers 24 and 25 that were used before. Therefore, the implementation process will be described with reference to the drawings.
By putting the wood chip 19 into the hopper 20 (10 to 30 millimeters), it enters into the rotor compressor at the same time, and compression is started. The rotation speed of the rotor 15 is different from that of the rotor 11, and the wood is made into a rice cracking shape by applying a tearing force simultaneously with the compression action from the left and right, and at the same time the wood is destroyed, the compressed wood material 23 is generated .
The produced substance 23 is conveyed by the conveyor 22 and is further broken by being put into the wood chippers 25 and 24, whereby the inventive substance small-shaped woody material 26 shown in claim 2 is formed.

Although the present invention can achieve multiple effects, the most effective feature is aimed at an alternative to wood pellet fuel. Therefore, we believe it will become popular as a low-cost wood fuel heating material for general households.

Claims (2)

By passing the wood chip 19 in the hopper 20 through the driven chip wood compression apparatus in FIG. 2, the compression wood material 23 which is the present invention material and is compressed and deformed is generated. The feature of the compressed wood is that the minute wood fibers (feather-like material) present on the surface of the chip are reduced by the compression action, thereby preventing the wood chips from being entangled with each other. Furthermore, it is a substance that is compressed and has an effect of reducing the water content in the wood by generating heat when the wood shows destruction.
At the same time, the wood is compressed very thinly, so many gather together to show a fluffy aggregate. Therefore, it will be used as an alternative material for litter laid on the floor of livestock farms when raising livestock. Compressed wood material formed from roller compression with multiple features. By passing the wood material 23 formed in claim 1 through the wood chipper devices 24 and 25 using the belt conveyor 22 (driving action), the wood material is further reduced and a small-shaped wood material 26 which is the material of the present invention is formed. The
The feature of the present invention material has been developed as an alternative fuel for wood pellets for heating currently used, and has the feature that the production cost can be produced at a very low cost compared to the current wood pellets.
