Description

Rice chaff expanding device {Rice-Chaff Expanding Apparatus}

The present invention is to provide a chaff expansion device capable of mass production by securing rotational safety and being able to operate for a long time through a male-female-type plate-shaped stone-type expansion device.

The present invention relates to a chaff swelling device, and more particularly, to a chaff swelling device that destroys the chaff's hard tissue and has good water absorption properties by compressing and crushing the chaff under high temperature and high pressure. .

Rice bran is the main by-product produced during the operation of the Migok Treatment Plant and the Tojeong Plant, which accounts for about 17% of the grain (based on weight). The use of chaff is being avoided due to the sharp decrease in packaging, the high quality of packaging materials and the increase in transportation costs.

These rice husks are used as compost by crushing them with a grinder because coarse bristles are present on the surface, compacted with lignin, and deposited with silicic acid in epidermal cells, making the tissues strong and difficult to penetrate due to moisture penetration. However, when the rice husk is simply crushed and used, there is a problem in that it is difficult to use because the texture of the chaff is strong and the moisture is difficult to penetrate due to the nature of the chaff.

In addition, in the case of crushing rice husk with an existing grinder, there is a problem that the parts of the rice husk are frequently replaced due to severe wear of the grinder because the structure of the chaff is strong. In view of these problems, a chaff bulging device is known to expand and soften the tissue of chaff so as to improve the water absorption rate. In the case of the chaff, swelling chaff generally has a soft tissue and water absorption that is significantly different from crushed chaff. Because of its fast fermentation, gas generation is significantly reduced, and the water content and crushed particles are very constant. Due to these characteristics, expanded chaff can be used for various purposes such as moisture control agents, barn rugs, forages, horticultural soils, and rice cultivation soils.

Looking at the conventional chaff expansion device, the outlet is formed in the cylindrical casing compressing the introduced chaff to discharge the expanded chaff in the horizontal direction and is configured to taper so that the end face of the cylindrical casing is narrowed, and at the same time, the spiral screw in the cylindrical casing It is configured to rotate and compress the screw shaft provided with it, and it is tapered so that the end face of the screw shaft is narrowed to expand and soften the chaff.

That is, in the conventional chaff expansion device, when the chaff is compressed by rotating the screw shaft while adding the chaff, the chaff is heated by compression, and the compressed chaff is released into the atmosphere from the outlet of the end of the cylindrical casing to crush the chaff at the same time as adiabatic expansion. It is supposed to.

The expanded chaff produced by the chaff-expansion device is formed with a smaller particle size than the chaff as a raw material, and the particle size of the chaff is made smaller by reducing the gap formed between the screw shaft and the outlet wall. It is possible to roughen the grains of the expanded chaff by increasing the gap.

However, the conventional horizontal chaff expansion device is supported by a bearing only on the opposite axis where the screw shaft is tapered in the cylindrical case, so that the horizontal shaking of the screw shaft increases when rotating, and the horizontal shaking becomes larger due to the uneven distribution and the uneven distribution of the chaff. As a result, the rotational moment of inertia is not constant, resulting in fatigue failure of the screw shaft, and the wear rate of the screw is high, so the replacement time is shortened.

1) In the Republic of Korea Patent Application No. 10-2005-0038720 as a chaff expansion device, a main body, a transfer screw disposed on the upper portion of the main body to transport chaff, and a hopper disposed at the bottom of the conveying screw to input chaff , Chaff expansion device having a cylindrical casing formed inside the body, a rotating shaft disposed to penetrate the cylindrical casing, and a pressurized and quantitative chaff supply screw formed on the outer surface of the rotating shaft and a discharge port for discharging the expanded chaff to the outside It is characterized by and has been described as being able to safely produce expansion, but it has the disadvantage of overlooking a decline in productivity or expansion performance compared to a millstone type as a screw type.

2) In the Republic of Korea Patent Application No. 10-2006-0075660, chaff expansion device, similar to the contents of 1), inserts a spacer adjustment liner to adjust the spacing of the finish when using a long time of the expansion screw and the spiral teeth of the expansion housing Although it uses a method, it shows a shortcoming that it is insufficient to explain whether the material of the gap adjusting liner can be used for a long time.

3) In the Republic of Korea Patent Application No. 10-2005-0090064, a method and a manufacturing device for puffed rice husk pellets, by softening and pelleting rice husks, the tissue softens and becomes a good compost that absorbs nitrogen and moisture well, and rice bran (board rice bran) ) There is an advantage of extruding into pellets of a predetermined shape size by mixing, but the detailed description of the process of expanding and the device for expanding is showing the disadvantages of insufficient.

In the case of the above-mentioned existing invention, various methods are proposed as a chaff expansion device, but as in the present invention, the present invention secures rotational safety through a male and female coupling type plate-shaped expansion device and enables long-term operation. There is no case of providing a chaff expansion device capable of mass production.
