Description

  The present invention is mainly used in the case of pruning materials other than the parts used as wood and bamboo such as wood and bamboo, end materials, remaining materials, etc. without using chips or chopping in advance. The present invention relates to a pulverization apparatus that can directly pulverize even if it remains in a long state or a large lump state.

  Conventionally, in the use of wood, the part other than the use of timber is made into chips and used for paper making or firewood use, and it is difficult to sell it. It was about. For this reason, forests and bamboo forests have become aging, and it has become difficult to generate maintenance costs.

However, due to the recent waste of fossil energy resources, the depletion of fossil energy resources, the global warming problem due to CO2 emitted by combustion, and the food problems including livestock feed received from bioethanol production, etc. Unused plant resources such as bamboo are expected to be widely used in addition to renewable energy sources and livestock alternative feeds.

It is considered that miniaturization is a keyword for the utilization of this unused plant resource. However, as a conventional technique for making trees finer, there are many uses of chip materials for papermaking or the like. The mainstream method is to use a cutter wheel to make a chip by shearing primary cutting with a cutter knife incorporated therein and then grinding and secondary processing with a hammer knife. In the case of a finer powder than the chip-shaped material, there is a ground powder that is produced as a secondary product during sawing, but this is not a manufacturing purpose and the amount of the product is limited. In addition, there has been almost no demand for powdered materials such as wood and bamboo until now, and when powdered materials such as wood and bamboo are necessary, generally a method of pulverizing the chip-shaped material with a roller mill or the like Is considered to be used. For this reason, there are hardly any pulverization apparatuses that can directly pulverize and produce wood, bamboo, or the like from a long or large block state without going through a chip forming process.

For example, Patent Document 2 has been proposed as a few examples of techniques aimed at directly finely pulverizing without forming chips. However, as a subject to be pulverized by this technology, small objects such as bark and cane scraps, paper scraps, plastic scraps, etc. are mainly targeted, and one main purpose is to rationalize pneumatic transportation of the pulverized body by connecting a blower. Yes.

In the above proposal, a drum in which a plurality of saw blades having the same diameter are continuously assembled through a spacer is used as a grinding means, and a plurality of holes are provided in the outer peripheral portion of the saw blade assembly for grinding. The inlet is also in the vertical direction, the stress during pulverization becomes large, and it is not easy to maintain the shape of the drum, and it can be expected that small pieces or the like slightly larger than the chip state can be directly pulverized. It is considered difficult to pulverize scales and large chunks. Considering the fact that circular saws of the same diameter are connected via a spacer as an example of the shape of the saw blade assembly, since it is not cut in the spacer, it is longer if the width of the spacer is large. Those that remain in the scale or large lump state are not easily pulverized, and if the width of the spacer is made too narrow, there is a greater risk of pulverized material remaining between the circular saws. If the width is extremely narrow, it will be the same as cutting with gears, and it will be necessary to increase the horsepower of the prime mover for pulverization, and there is no possibility of pulverized material to escape, so the pulverization efficiency may be extremely reduced Conceivable. For this reason, it is not possible to attempt to pulverize a long or large block of wood, bamboo, etc. with the current state of the art, omitting the processing steps such as chipping or fragmentation. It is considered difficult.

In order to meet the expectation of utilization of unused plant resources, it is necessary to expand the possibility of using parts other than wood timber and charcoal use, bamboo bamboo material and bamboo charcoal use, only to make chips The use is limited, and if it is pulverized, it is expected to open up the possibility of using food additives and raw material blends in alternative feeds, fertilizers, straw beds, and bamboo. There is a demand for further miniaturization than the form. For this reason, there is a demand for an apparatus that can easily and easily pulverize wood, bamboo, etc. to a certain extent in a long or large mass.
