Description

Bamboo pellet and method for manufacturing same and manufacturing apparatus therefor {Bamboo pallet and Method for manufacturing and facility for manufacturing the same}

The present invention relates to bamboo pellets and a method for manufacturing the same and a manufacturing apparatus thereof, and more particularly, to select the bamboo as a pellet material that can replace the existing wood pellets and to produce the pellets using the bamboo material as the most optimal method It relates to a bamboo pellet and a manufacturing method and a manufacturing apparatus thereof.

Fossil fuels are widely used because they are easy to manage such as fuel injection and temperature control.However, fossil fuels are not only expensive, but are also very expensive and are recognized as pollutants that destroy the environment such as carbon dioxide emitted during combustion causing global warming. .

Therefore, efforts are being made to use wood as a source of energy, which is low in carbon dioxide and relatively inexpensive compared with fossil fuels.However, when burning firewood, chips or sawdust as it is, the shape of the fuel is irregular and the calorific value per unit volume of the existing fuel Compared to the lower level, industrial use was impossible.

Therefore, the wood pellets manufactured by compressing the wood, that is, sawdust, large fat rice or ground chips, under high pressure and high temperature, have high heat generation per unit volume and have a constant shape and size, thereby providing a stable heat source. In recent years, it is a very useful fuel in terms of industrial use.

At this time, the wood pellet (pellet) has been internationally set in order to enable a fixed quantity supply by making the shape and size constant, mainly the diameter is 4 ~ 10mm, the length is 3 ~ 5 times the diameter.

However, recently, as wood raw materials such as sawdust, large fat rice, or ground chips are widely used as raw materials for floor coverings and natural fertilizers, sufficient pellet production cannot be secured. to be.

In addition, in order to manufacture wood pellets, raw materials input process, sorting process, grinding process, drying process, pelletization process, cooling process, sorting and packaging process have to go through various processes. Especially, wood pellets must be more homogeneous before pelletizing. However, since various types of wood are mixed, the homogeneity is poor. In particular, wood with low lignin content such as hardwoods has disadvantages such as the addition of expensive additives such as starch.

Also, to get enough wood to be used as wood pellets, it has to be grown for more than three years, and cutting other wood to make wood pellets is another deterioration of the natural environment, which is a good alternative to fossil fuels. It is not a good way for the future of our planet.

Therefore, the inventors of the present invention are looking for a material that can replace wood pellets from a completely different perspective, while the water pipes between the bamboos are weak, thin, and hollow, and thus have a low water content compared to other woods. It has been found that the flammability is very good without doing so. In addition, bamboo has a tremendous growth capacity, which allows it to grow enough to be used as a pellet material in three months, and has good yielding capacity and high density and high yield per unit area, and is widely distributed in subtropical areas. It was found that the material of the pellet was sufficient.

However, bamboo is composed of a neck, a yarn, a flow cell, and a milk tube sokcho, and has a disadvantage that it is difficult to manufacture in the form of sawdust or chips, which is a previous stage of pellets, because it is made of a very tough fiber with a dense bundle of milk tube sock.

Therefore, the present invention was devised to solve the above problems, and if the purpose of the development of wood pellets is limited to simply using wood as an energy source, the diameter of bamboo pellets is 4 ~ 10mm, the length is 3 ~ If it had a size of 5 times, it was judged that it could be used as a sufficient energy source as there was no problem in quantitative supply like the existing wood pellets. For this purpose, the bamboo was cut but the diameter was 4-10mm, and the length was 3-5 It is to provide a bamboo pellet obtained by cutting in the size range of the pear.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a method for producing bamboo pellets by first flattening the bamboo (A) by flattening step, cutting the flattened bamboo in the longitudinal direction, and cutting the vertically cut bamboo in the horizontal direction again. Is done.

In the present invention, flattening means flattening the flat cylindrical bamboo or semi-circular shape (splitting the bamboo in half in the longitudinal direction) and flattening, and thus flattening the flat pressing the bamboo (A) in the present invention. The reason is that when the cylindrical or semi-circular bamboo is to be cut in the longitudinal direction, that is, in the longitudinal direction, a space is created between the work table and the bamboo and is unstable, and it is not easy to cut. In particular, the bamboo has a characteristic that it is well split in the longitudinal direction is preferably cut in a row to increase the cutting efficiency, for this reason it is necessary to maintain a flat state of bamboo.

In addition, the present invention in the manufacture of the bamboo pellet may be made by the circular cross-section, or by pressing the bamboo in order to increase the calorific value per unit volume, in this case before cutting in the longitudinal direction to facilitate the deformation of the bamboo Bamboo must be heated by heating means in advance. The heating means is preferably formed on the upper and lower portions of the bamboo so that the entire bamboo is heated.

The heated bamboo is pressurized by a pair of pressing rollers formed so that a plurality of semicircular grooves and blades are repeated around the surface of the bamboo to cut the bamboo in the longitudinal direction and to press the bamboo to make a circular cross section. It is formed.

In addition, the present invention can remove the endothelial side of the low fiber density to increase the calorific value per unit volume and manufacture pellets only with the outer skin. In this case, the cylindrical bamboo is cut in half, the endothelial portion It is preferable to make it face down. This is because the endothelial removal is easily performed by being cut at the same time as the bamboo endothelial removal device 170 is installed below the work table and has a blade rotating at high speed. Of course, only the discarded bamboo endothelium can be collected again to produce pellets by known wood pellet processes.

Bamboo pellet manufacturing apparatus 100 of the present invention is a bamboo flattening device 110 for flattening the bamboo (A) large and the vertical longitudinal cutting device 120 for cutting the flattened bamboo in the vertical direction, and Bamboo transverse cutting device 130 for cutting the longitudinally cut bamboo in the horizontal direction again.

The bamboo flattening device 110 is composed of a pair of flat rollers 111, the inclined surface 113 is formed on a portion of the outer peripheral surface of the flat rollers 111. This is because the bamboo is flattened and flattened so that it has a considerable diameter, so if there is no slope 113 on the roller 111, it is not easy to bite bamboo. Therefore, the inclined surface 113, it is preferable to form a rough concave-convex portion on the surface so as to easily enter the bamboo.

Bamboo, which is inherited by the flat roller 111, is pressed flat to the portion after the inclined surface 113, which is spaced apart from other portions of the flat roller 111 except for the inclined surface 113. Because it is only about twice as long, bamboo is inevitably flattened.

However, the problem is that there is a bark of bamboo, the thickness of the section is significantly thicker than the general thickness, so if you fix the separation interval of the flat roller 111, there is a fear of breakage of the bark section of the bamboo or flat roller (111) There is a problem of going to the axis. In addition, when the spacing interval of the flat roller 111 is fixed, the spacing when the inclined surfaces 113 face each other is too wide to press the bamboo perfectly, thus causing a slight problem in the flattening operation,

Therefore, in order to solve the problem, the axis of the flat roller 111 located above the flat roller 111 may be moved up and down by the long hole 112 formed in the frame 101. Do. As a result, the bamboo can be flattened at any portion of the flat roller 111, and the flat roller 111 pressurizes the bamboo by the weight of the upper flat roller 111.

In this case, in order to increase the pressing force, a spring force may be applied to the shaft of the upper flat roller 111 to apply a stronger pressure.

Bamboo longitudinal cutting device 120 is for cutting the bamboo pushed out flat by the flattening device 110 vertically, that is, in the longitudinal direction, consisting of a pair of vertical cutting roller 121. The vertical cutting roller 121 is to cut the bamboo cutting up and down while the blades of the upper and lower vertical cutting roller 121 is engaged with each other, which is the smallest because the grain of the bamboo is formed in the longitudinal direction The easiest way to split bamboo is by force. Of course, instead of the vertical cutting roller 121, a plurality of circular blades that rotate can be arranged at regular intervals, which consumes a lot of energy in the rotation of the blade and also generates a lot of wasteful elements such as bamboo sawdust as the blade thickness. It is not a preferred method because it loses.

Alternatively, instead of the vertical cutting roller 121, a plurality of sharp blades may be fixed vertically at regular intervals, and may be configured to be split vertically by the propulsion pressure of the bamboo. The blade has a disadvantage of dullness, which is also not a preferred method.

In addition, the vertical cutting roller 121 may make the cutting of the bamboo easier by forming a sharp blade in the interlocking portions as shown in Figure 3, the gap between the blade and the blade as shown in Figure 3 (H) will eventually be the width or height of the bamboo pellet 300 produced by the present invention.

In the present invention, the upper and lower longitudinal cutting rollers (120a) surface as shown in Figure 7 so as to be pressed at the same time cutting to make a circular cross-sectional shape of the bamboo in the longitudinal direction in the bamboo cutting in the longitudinal direction The plurality of semi-circular grooves 121a and the blades 122a may be formed to be repeated around the ice. In this case, in order to help the deformation of the bamboo to facilitate the pressing of the bamboo more may be formed a heating means 190 having a heater 191 between the bamboo flattening device 110 and the bamboo longitudinal cutting device 120. At this time, the heating means 190 may be installed on both the upper and lower portions so as to heat both the upper and lower portions of the bamboo. In this case, the heater 191 may be a heating wire or a halogen lamp.

Bamboo horizontal cutting device 130 is for cutting the bamboo cut in the longitudinal direction by the vertical cutting roller 121 horizontally, that is, perpendicular to the longitudinal direction of the bamboo, a pair of horizontal cutting roller 131 Is done. The horizontal cutting roller 131 is the upper and lower blades of the horizontal cutting roller 131 are engaged with each other to cut the already vertically cut bamboo at a predetermined interval (L), as is well known bamboo cut in the horizontal direction Although most difficult to do, in the present invention, since the bamboo is already divided into several branches in the longitudinal direction, a large force is not required to cut in the transverse direction.

In addition, the horizontal cutting roller 131 may be made easier to cut the bamboo by forming a sharp blade in the interlocking portion as shown in Figure 1, the gap between the blade and the blade as shown in Figure 3 (L) will eventually be the length of the bamboo pellet 300 produced by the present invention.

The present invention forms a bamboo endothelial removing device 170 between the bamboo flattening device 110 and the vertical longitudinal cutting device 120 in order to remove the endothelial side of low fiber density in order to increase the amount of heat generated per unit volume. You may. At this time, the bamboo endothelial removal device 170 is preferably installed in the lower workbench, the pressure roller 180 is formed on the upper portion of the bamboo endothelial removal device 170 to prevent the hearing of the bamboo when the endothelial removal.

In the present invention, between the bamboo flattening device 110 and the bamboo longitudinal cutting device 120, the bamboo longitudinal cutting device 120 and the bamboo horizontal cutting device 130 is an auxiliary pressure roller as shown in FIG. It can be configured to form a plurality. That is, the auxiliary pressure roller between the bamboo flattening device 110 and the bamboo longitudinal cutting device 120 presses the bamboo exiting the bamboo flattening device 110 to guide the bamboo vertical cutting device 120 to a more stable state. The auxiliary pressure roller between the bamboo longitudinal cutting device 120 and the bamboo horizontal cutting device 130 is configured to press the bamboo exiting the bamboo vertical cutting device 120 to make the bamboo horizontal cutting device more stable ( 130) to guide the configuration.

One end of the bamboo horizontal cutting device 130 is formed with a hopper 160 for collecting the bamboo pellet 300 is cut off.

The bamboo pellets 300 of the present invention are 4 to 10 mm in diameter obtained by the bamboo pellet manufacturing method and apparatus described above, and the length means bamboo having a size of 3 to 5 times the diameter. In this case, since the diameter is an expression limited to bamboo pellets having a circular cross-sectional shape, in the case of bamboo pellets having a rectangular cross-sectional shape, it means a width or a height. Therefore, if the diameter of the bamboo pellet in the present invention is 4mm, the length will be 12 ~ 20mm.

The present invention as described above in detail according to each step is as follows.

First, when the well-grown cylindrical or semi-circular bamboo is placed on the conveyor belt 150, the bamboo is flattened by being bitten by the bamboo flattening device 110, and thus the flattened bamboo discharged from the bamboo flattening device 110 is vertically bamboo. It is split vertically while being inherited by the direction cutting device 120.

The vertically divided bamboo is then split horizontally again by the bamboo horizontal cutting device 130 is eventually put in the hopper 160.

The bamboo pellets 300 contained in the hopper 160 are transported by the transport means and packed by the packaging apparatus.

Although the present invention has been described by the limited embodiments as described above, the present invention is not limited thereto and the technical spirit of the present invention and a patent to be described below by those skilled in the art to which the present invention pertains. Various modifications and variations will be possible within the scope of the claims.
