Description

[0001] PELLET MAKING EQUIPMENT [0002]

The present invention relates to a pelletizing apparatus capable of producing various kinds of raw materials as excellent pellets.

Due to the global economic recession, high oil prices, resource depletion, global warming, etc., the use of conventional fossil fuels and their utilization have been restricted, and the development of resources and technologies to replace fossil fuels has been requested more recently .

In particular, in order to reduce the use of fossil fuels for heating, a variety of technologies have been developed to recycle the wood that has just been thrown away in recent years as a resource. In other words, in a form for using wood as a fuel for heating, techniques and apparatuses for making solid fuel by making wood into sawdust are being developed in various forms.

For example, pellets produced by compressing sawdust, which is a byproduct of wood, into a certain size are being produced in large quantities using heating fuel, and the use thereof is also increasing.

On the other hand, pellets are solids obtained by compression molding of the raw materials at a high pressure. Depending on the raw materials, pellets are also used for various purposes such as fuel, fertilizer, and feed.

The technique of agglomerating raw materials when raw materials are formed is important in the production of such pellets. Conventionally, raw materials can not be agglomerated effectively, and it has been difficult to produce excellent pellets for various raw materials.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a process diagram schematically showing a pellet production apparatus according to a first embodiment of the present invention, FIG. 2 is a structural view showing electrical connection of a pellet production apparatus according to a first embodiment of the present invention, 2, structural characteristics of the pellet production apparatus according to the first embodiment of the present invention will be described.

The apparatus for producing pellets according to the first embodiment of the present invention comprises a raw material supply device 10, a liquid binder supply device 20, a solid-state binder supply device 30, a steam generator 40, a mixing device 50 , A moisture measurement sensor 60, a control device 70, and a pellet molding machine 80 to produce excellent pellets.

The raw material supply device (10) supplies a general raw material or powder raw material to the mixing device (20). At this time, the general raw material or the raw material of the powder is stored in the hopper provided in the raw material supplying device 10. Here, the term " raw material " refers to raw materials having moisture content (e.g., herbaceous trees, wood chips, grains, sludge, By-product of wood-fired power generation and by-products generated during the woodpellet mixing process at the power plant) through the grinding apparatus. On the other hand, raw materials (including general raw materials and powder raw materials, hereinafter referred to as raw materials, both of general raw materials and raw materials of powder) include various kinds of raw materials that are manufactured and used in the form of pellets such as fuel, fertilizer, feed, food, The raw material is applied.

The liquid binder supply device 20 agitates the water and the binder and supplies them to the mixing device 20. At this time, the agitated liquid binder is prepared by mixing 0.05 to 3.5% by weight of Cassava starch with respect to 100% by weight of water. On the other hand, in addition to the cassava starch, a variety of starches (for example, sweet potatoes, potatoes, corn, rice, wheat, etc.) may be used as the liquid binder and the following solid binder.

The solid-state binder supplying device (30) supplies the granular solid-state binder to the mixing device (20). At this time, the solid binder is preferably prepared by using Cassava starch, preferably by drying the cassava liquid binder. On the other hand, the solid-state binder supplying device 30 preferably has a stirring function so as to prevent the solid-state binder from aggregating.

The steam generator 40 receives water and heats the steam to spray the steam to the mixing device 50. At this time, the steam is preferably sprayed at a high pressure.

The mixing apparatus 50 receives the liquid binder from the liquid binder supply device 20, the solid binder from the solid-state binder supply device 30, and the steam from the steam generator 40, Is mixed with the raw material from the above. At this time, the mixing device 50 stirs the raw material to have an appropriate moisture content so that the raw material is in a state suitable for pellet molding.

The moisture measurement sensor 60 measures the moisture content of the raw material supplied to the mixing device 50. In this embodiment, the moisture measurement sensor 60 is preferably installed in the raw material supply device 10 to measure the moisture content of the raw material.

The control device 70 includes a raw material supply device 10, a liquid binder supply device 20, a solid-state binder supply device 30, a steam generator 40, a mixing device 50, 60, and a pellet molding machine 80. Particularly, the control device 70 selectively controls the liquid binder supply device 20, the solid-phase binder supply device 30 and the steam generator 40 according to the measurement signal according to the moisture measurement sensor 60, ), The amount of the solid binder, and the amount of steam.

For example, when the control device 50 receives a measurement signal indicating that the water content of the raw material is lower than a preset reference value from the moisture measurement sensor 60, the controller 50 controls the liquid binder supply device 20, And supplies the high-temperature steam to the mixing device 50 via the steam generator 40, if necessary. Then, the raw material in the mixing device 50 is mixed with the liquid binder and stirred to form a pellet-shaped state. At this time, the temperature of the steam inside the mixing device (50) is increased so that the raw material is mixed well with the liquid binder.

The control device 50 controls the solid-state binder supply device 30 to supply the solid-state binder to the mixing device 50 when receiving the measurement signal that the moisture content of the raw material is higher than the predetermined reference value from the moisture measurement sensor 60, And supplies the high-temperature steam to the mixing device 50 through the steam generator 40. [ Then, the raw material in the mixing device 50 is mixed with the solid-phase binder and mixed in a pellet form. At this time, the steam increases the temperature inside the mixing device (50) and melts the solid binder so that the raw material is mixed well with the solid binder.

Meanwhile, in the present embodiment, the controller 70 uses a liquid binder and steam as the low-moisture powder material, and uses a solid-state binder and steam as the high-moisture raw material. However, depending on the kind or the water content of the raw material, The binder, and steam may be supplied to the mixing device 50. [

In addition, in the present embodiment, the control device 70 can operate and control the configuration used in the present embodiment in addition to the above-mentioned configuration, and each configuration may be separately controlled separately from the control device 70. [

The pellet molding machine 80 receives the raw material from the mixing device 50 and forms it into pellets. In this embodiment, the pellet molding machine 80 can be applied to various devices as long as the material can be molded into a pellet shape.

The operation of the pellet molding apparatus according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

The raw material is stored in the hopper of the raw material supply device 10, and the raw material supply device 10 supplies the raw material to the mixing device 50 through the transfer device.

At this time, when a raw material (for example, sawdust) having a small amount of water is supplied to the mixing device 50, the control device 70 receives a measurement signal that the water content of the raw material is lower than the reference value from the moisture measurement sensor 60. The control device 70 then controls the liquid binder supply device 20 to supply the liquid binder to the mixing device 50 and supply the high temperature steam to the mixing device 50 through the steam generator 40 do. Here, the controller 70 may adjust the steam injection amount and the steam injection pressure of the steam generator 40 according to the kind of the raw material.

Further, when a general raw material (e.g., sludge) having a large amount of water is supplied to the mixing device 50, the control device 70 receives a measurement signal that the water content of the raw material is higher than the reference value from the moisture measurement sensor 60. The control device 70 controls the solid-state binder supply device 30 to supply the solid-state binder to the mixing device 50, and supplies the high-temperature steam to the mixing device 50 through the steam generator 40. [ Here, the control device 70 can adjust the steam injection amount and the steam injection pressure of the steam generator 40 according to the kind of the raw material and the water content of the raw material.

Thus, when the raw material is mixed with the binder (liquid binder or solid-state binder) in the mixing device 50, the raw material in the mixing device 50 is changed into a state suitable for molding in the pellet molding machine 80.

Thereafter, the raw material of the mixing device 50 is supplied to the pellet molding machine 80 according to the amount set through the raw material quantity feeder, and the pellet molding machine 80 molds the pellets according to the purpose of the raw material.

Subsequently, the pellets molded in the pellet molding machine 80 are selected in a pellet sorting transfer device, and the pellets conforming to the standard are contained in the ton back provided in the ton backing stand. At this time, the pellet sorting and conveying device is provided with a dust collecting device to remove dust generated when pellets are sorted.

On the other hand, in order to well form the raw material into pellets, it is very important how the liquid binder or the solid binder used above binds the raw materials well.

Table 1 shows the results of mixing the liquid binder with the raw material (sawdust) by mixing the cassava, the sweet potato starch and water, the potato starch and the water mixture ratio, After drying, the impact was applied at the same pressure, and the binding force of each of the liquid binder-based raw materials was measured. At this time, the amount of debris generated when the liquid binder binder mixed material according to the cassava was impacted was 1.0, and the relative amounts of the respective liquid binder blend materials were shown relatively.

100% by weight of starch (cassava, wheat, corn) The amount of debris produced by mixing the cassava starch mixture Amount of debris produced by sweet potato starch mixture Amount of debris produced by potato starch mixture 0.05 wt% 1.0 1.5 1.7 1.0 wt% 1.0 1.5 1.7 2.0 wt% 1.0 2.0 2.1 3.5 wt% 1.0 2.2 2.2

As shown in Table 1, it can be seen that the liquid binder-mixed raw material mixed with the liquid binder using cassava starch produced less debris when the same impact was applied than the liquid binder mixed with the liquid binder using the sweet potato starch and potato starch . This indicates that the liquid binder using cassava starch has better bonding strength than the liquid binder using sweet potato starch and potato starch.

FIG. 3 is a schematic view for explaining a mixing apparatus according to a second embodiment of the present invention. Referring to FIG. 3, a pellet manufacturing apparatus according to a second embodiment of the present invention will now be described.

The apparatus for producing pellets according to the second embodiment of the present invention is provided with the stirring transfer device 51 in the mixing device 50. [ In the present embodiment, the stirring transporter 51 is composed of a rotating shaft 51a and a blade 51b provided at the periphery of the rotating shaft 51a. At this time, the stirring transporter 51 is a conventional one for stirring and conveying the mixture in the mixing device 50. The wing 51b may be an impeller type or a screw type, and the mode may be variously modified.

Meanwhile, in the pellet manufacturing apparatus according to the second embodiment of the present invention, the rotating shaft 51a of the stirring and conveying unit 51 is made of an electromagnet, and the blade 51b is made of a metal material.

At this time, the rotating shaft 51a of the stirrer 51 is connected to both ends of a coil provided inside, and each electric wire is connected to a power source, thereby functioning as an electromagnet. The electric wires connected to both ends of the rotary shaft 51a are preferably connected through separate connectors so that the rotary shaft 51a is not twisted by the rotation of the rotary shaft 51a when the rotary shaft 51a is rotated. Is a technique well known in the art and can be easily carried out.

When the rotating shaft 51a of the stirring device 51 is energized by electricity and the wing 51b is also magnetized by the rotating shaft 51a in the mixing device 50 according to the present embodiment, The metal material contained in the raw material is attached to the rotating shaft 51a or the blade 51b when the stirring is performed so that the metallic material mixed with the raw material is separated from the raw material. Accordingly, the pellets molded in the pellet molding machine 80 are manufactured to be more suitable for use.

At this time, after the pellet manufacturing process is completed, when the worker cuts off the power supply to the coil in the rotary shaft 51a of the stirrer 51, the rotary shaft 51a and the blade 51b lose their magnetic force, The metal material attached to the blade 51a and the blade 51b falls due to its own weight. Therefore, the metal material can be more easily removed in the mixing device 50, so that it is easy to clean, and it is possible to effectively prevent the existing metal material from being mixed with the raw material when the mixing device 50 is restarted in the future.

A pellet manufacturing apparatus according to a third embodiment of the present invention will now be described.

In the pellet producing apparatus according to the third embodiment of the present invention, the stirrer 61 provided in the mixing device 50 is made of a magnet material. The stirring transporter 51 in this embodiment has the same structure as that of the second embodiment but comprises a rotating shaft 51a made of a rigid material and a wing 51b made of a magnet material and provided at the periphery of the rotating shaft 51a.

Therefore, when stirring the raw material in the mixing device 50, it is possible to effectively remove the metal material (for example, flour, usually generated from the crushing device upon crushing the raw material by the crushing device) mixed with the raw material.

That is, when the blade 51b of the stirrer 51 is rotated, the metallic material adheres to the blade 51b, so that the metallic material mixed with the raw material is separated from the raw material. Accordingly, the pellets molded in the pellet molding machine 80 are excellently manufactured to be more suitable for use.

FIG. 4 is a process diagram showing a pellet production apparatus according to a fourth embodiment of the present invention, FIG. 5 is a structural view showing an electrical connection of the pellet production apparatus according to the fourth embodiment of the present invention, and FIGS. 4 and 5 A pellet manufacturing apparatus according to a fourth embodiment of the present invention will now be described with reference to FIGS.

As mentioned above, it can be seen that cassava has a better binding force than sweet potato and potato when used as a binder. However, cassava contains toxins (eg, tapioca, a starch taken from cassava root roots), which pose a risk when producing pellets for feed use. Therefore, the present embodiment further includes a device for removing the toxin of cassava, and the structure of some components is changed.

This embodiment further includes a temperature measuring sensor 90, a cassava supplying device 100 and a cassava immersing device 110 and includes a liquid binder supplying device 20 and a solid-phase binder supplying device 30 and a steam generator 40 and the control device 70 are modified.

The temperature measuring sensor 90 is installed in the mixing device 50 to measure the temperature in the mixing device 50. [

The cassava supplying device 100 powders the cassava and supplies it to the cassava immersion device 110. [

The cassava immersion device 110 has a water reservoir structure capable of holding water, and immerses the cassava for a predetermined time to remove toxins contained in the cassava.

The liquid binder supply device 20 and the solid-state binder supply device 30 are configured such that the cassava liquid binder in the liquid binder supply device 20 and the cassava solid binder in the solid-phase binder supply device 30 are supplied to the steam column from the steam generator 40 . Particularly, the solid-state binder supply device 30 dries the wet cassava powder in the cassava immersion device 110 through the steam heat to remove the toxins that may remain in the cassava powder through the high heat while reducing the moisture content of the cassava powder .

On the other hand, in the liquid binder supply device 20 and the solid-state binder supply device 30, a steam passage is formed on the inner wall of the storage tank containing the liquid binder and the solid binder, and steam from the steam generator 40 passes through the steam passage , Indirect heat exchange is performed at the inner wall of the storage tank, and the cassava solid binder and the cassava liquid binder are supplied with heat through the indirect heat exchange.

The control device 70 analyzes the measurement signal from the temperature measurement sensor 90 so that when the temperature in the mixing device 50 is higher than the reference value, the steam from the steam generator 40 is supplied to the liquid binder supply device 20 and the solid phase To be supplied to the binder supply device 30. Then, the steam from the steam generator 40 is indirectly heat-exchanged with the liquid binder supply device 20 and the solid-state binder supply device 30 while raising the temperatures of the liquid binder supply device 20 and the solid-phase binder supply device 30 , And is supplied to the mixing device (50). At this time, since the mixing device 50 maintains the temperature higher than the reference value, the steam from the steam generator 40 maintains the internal temperature even though the steam passes through the liquid binder supply device 20 and the solid-phase binder supply device 30 It is not greatly affected.

The operation of the pellet production apparatus according to the fourth embodiment of the present invention will be described with reference to FIGS. 4 and 5. FIG.

The control device 70 drives the temperature measuring sensor 90 when a signal for supplying heat to the liquid binder supplying device 20 and the solid state binder supplying device 30 is inputted to the control device 70. [

The control device 70 analyzes the measurement signal from the temperature measurement sensor 90. When the temperature in the mixing device 50 is higher than the reference value, steam from the steam generator 40 is supplied to the liquid binder supply device 20, And the solid-state binder supply device 30 as shown in FIG. Then, the steam from the steam generator 40 is indirectly heat-exchanged with the liquid binder supply device 20 and the solid-state binder supply device 30 while raising the temperatures of the liquid binder supply device 20 and the solid-phase binder supply device 30 , And is supplied to the mixing device (50).

On the other hand, when a signal to use the cassava as a binder is inputted to the control device 70, the control device 70 drives the cassava supply device 100 to supply the cassava powder to the cassava immersion device 110, After immersed in the cassava immersion device 110 for a certain period of time, the cassava powder is supplied to the liquid binder supply device 20 and the solid-phase binder supply device 30.

At this time, the cassava liquid binder in the liquid binder supply device 20 and the cassava solid binder in the solid-state binder supply device 30 are heated by the heat from the steam generator 40.

Then, the cassava liquid binder and the cassava solid binder are supplied to the mixing device 50 under the control of the control device 70 according to the first embodiment.

FIG. 6 is a view showing a pellet molding machine according to a fifth embodiment of the present invention, and FIGS. 7 and 8 are views showing a part of FIG. 6, wherein the pellet molding machine according to the present embodiment The following is an explanation.

A conventional pellet die type pellet molding machine is equipped with a reservoir 81, a pellet molding machine main body 82 and a presser 84 to mold the pellet.

The reservoir 81 is filled with the raw material and stored.

The pellet molding machine main body 82 has a receiving portion 82a in which a space is formed and a plurality of pellet molding holes 82b1 penetrating the upper and lower chambers and a pellet forming mold And a pellet discharge portion 82c provided on a side surface of the receiving portion 81a and through which pellets are discharged. In this embodiment, the pellet forming mold 82b has a disk shape, and may be modified in various ways as long as it has a plate shape.

The pressurizer 84 includes a drive portion 84a located at the center of the upper portion of the pellet forming mold 82b of the pellet molding machine main body 82 and a roller 84b formed with a concave portion and a groove portion at the periphery thereof and rotated by a drive portion 84a ), And presses the raw material to the pellet forming mold 82b. In this embodiment, two rollers 84b are provided on both sides of the driver 84a.

In such a conventional pellet molding machine, the raw material pressurized by the roller 84b of the presser 84 passes through the pelletizing hole 82b1 of the pellet forming mold 82b, and is discharged as pellets. At this time, if the raw material contains a large amount of foreign matter or the moisture is not controlled properly, the pellet forming hole 82b1 of the pellet forming mold 82b is easily clogged, thereby reducing the pellet production amount or making the pellet itself impossible.

Therefore, conventionally, the pellet forming hole 82b1 of the pellet forming mold 82b is pierced with a drill, and this operation not only increases the workload of the operator but also takes a lot of time to drill a large number of pellet forming holes 82b1 It was very inefficient.

The pellet die pellet molding machine 80 according to the present embodiment for solving such a problem further includes a guide panel 83, a pushing device 85, and a pellet discharging device 86.

The guide panel 83 has a guide hole 83a corresponding to the pellet molding hole 82b1 of the pellet forming mold 82b and penetrating the guide hole 83a in the vertical direction. The guide panel 83 is inserted in the receiving portion 82a of the pellet molding machine main body 82, And a lower portion than the pellet discharge portion 82c.

The pushing device 85 is provided with a pushing member 85a and a pushing device 85b to pierce the pellet forming hole 82b1 of the pellet forming mold 82b.

The pushing member 85a includes a moving panel 85a1 accommodated in the receiving portion 82a of the pellet molding machine main body 82 and positioned below the guide panel 83 so as to be movable up and down, And a plurality of push bars 85a2 provided on the upper portion of the moving panel 85a1 and passing through the guide hole 83a of the guide panel 83 and the pelletizing hole 82b1 of the pellet forming mold 82b.

The pushing device 85b supplies the hydraulic or pneumatic pressure to the receiving portion 82a of the pellet molding machine main body 82 to move the pushing member 85a up and down. In this embodiment, the pushing device 85b includes a first connection line 85b1 connected to the receiving portion 82a of the pellet molding machine main body 82 so as to be positioned below the moving panel 85a1, A second connection line 85b2 connected to the receiving portion 82a of the first panel 82 and connected to the upper portion of the moving panel 85a1 and a first connection line 85b1 and a second connection line 85b2, And a pump 85b3 for providing pneumatic or hydraulic pressure to the connecting line 85b1 and the second connecting line 85b2 to move the pushing member 85a up and down. In this embodiment, the pump 85b3 may be a pneumatic pump or a hydraulic pump. Meanwhile, in the present embodiment, a technique using pneumatic or hydraulic pressure is applied to the pushing device 85b. However, if the pushing member 85a can be moved up and down, various techniques such as a technology using a ball screw can be applied.

The pellet discharging device 86 is connected to the receiving portion 82a of the pellet molding machine main body 82 and has a connecting line 86a connected to the upper portion of the guide panel 83, And a pneumatic pump 86b for providing pneumatic pressure to the line 86a so as to push the pellet falling onto the upper portion of the guide panel 83 toward the pellet discharge portion 82c of the pelletizing machine body 82. [

FIG. 9 is a view for explaining the operation of the pellet molding machine according to the fifth embodiment of the present invention. Referring to FIG. 9, the pellet manufacturing according to this embodiment will be described as follows.

The pellet molding machine 80 drives the roller 84b of the presser 84 when the raw material from the mixing device 50 is supplied to the reservoir 81 of the pellet molding machine 80.
