Description

Pellet Manufacturing Equipment {PELLET MANUFACTURING APPARATUS}

The present invention relates to a pellet manufacturing apparatus, and more particularly, to a pellet manufacturing apparatus capable of miniaturization and light weight with a simple structure, excellent structural strength, and can improve production yield.

In general, boilers are used for heating of houses or public facilities as well as industrial. The fuel used in such a boiler is mainly oil or gas. Boilers are usually equipped with a temperature control device so that oil or gas is automatically supplied to the combustion chamber in accordance with the set temperature to provide the heat of combustion generated by ignition of fuel as a power source for heating and industrial equipment.

Oil or gas as a raw material of the boiler has the advantages of easy management of fuel injection and temperature control and high heat of combustion. Therefore, although a lot of oil or gas is used as a raw material of the boiler, the oil or gas is quite expensive, the fuel is consumed a lot, and the heating cost is increased, so the economic burden is large, and the combustion gas discharged during combustion pollutes the air. There is a problem of destroying the environment.

Recently, as described above, the spread of boilers using wood as a raw material, which is relatively inexpensive, is increasing compared to boilers using oil or gas. Such wood-based boilers can reduce heating costs and are more environmentally friendly than oil or gas.

In addition, as the number of power homes for people who want to escape from urban life and naturalize into nature increases, the spread of heating stoves using wood as a raw material is spreading. In particular, the use of wood-based boilers is increasing as a method for heating the interior of the plastic house in the farming method of growing various fruits and vegetables using the plastic house.

However, the method of using wood as described above has the advantage of reducing the fuel cost compared to oil or gas, but has the disadvantage of lowering the thermal efficiency compared to oil or gas, as well as wood due to the characteristics of a bulky solid combustion chamber There is a problem that is difficult to supply continuously. In addition, there is a cumbersome problem because the user has to manually remove the combustion waste generated by burning wood.

In order to solve this problem, recently, technologies for manufacturing pellet-type solid fuel using sawdust have been developed and used for the purpose of replacing fossil fuels and for the efficient use of wood resources. Such pellet-type wood fuel is produced by compression, so it may be useful in terms of economics because it is very heat-producing and thermal efficiency for a long time.

However, the conventional apparatus for producing wood pellets is not only very bulky, but also has a high noise, and a relatively long manufacturing time, which is difficult in terms of cost or in consideration of facility area.

For example, it will be described as being spaced apart at intervals of 120 degrees along the direction.

The widths and pitches of the pressure roller teeth 183, 186, 189 provided in each of the three pressure rollers 180, 185, and 188 are different from each other. That is, the width and pitch spacing of the pressure roller teeth 183, 186, 189 are the same in the same pressure roller and are different for different pressure rollers. The pressure roller teeth 183, 186 and 189 respectively provided in the plurality of pressure rollers 180, 185 and 188 are press rollers 180 and 185 along the rotational direction of the pellet forming drum 133 ( According to the arrangement order of the 188, the width is gradually provided in the plurality of pressing rollers 180, 185, 188 in the form of gradually increasing. In addition, the pressure roller teeth 183, 186, 189 provided in each of the plurality of pressure rollers 180, 185, 188 are press rollers 180, 185 along the rotational direction of the pellet forming drum 133. In accordance with the arrangement order of the 188), the pitch interval is provided in a plurality of pressing rollers 180, 185, (188) in the form of gradually decreasing.

Specifically, as shown in Figure 8, the first pressure roller (hereinafter referred to as "first pressure roller") disposed in the lower left of the three pressure rollers 180, 185, 188, and disposed above Pressure roller teeth 183 provided in each of the second pressure roller (hereinafter referred to as "second pressure roller") and the third pressure roller (hereinafter referred to as "third pressure roller") disposed on the lower right side. The width and pitch interval of (186) and 189 are different from each other. Assuming that the rotation direction of the pellet-forming drum 133 is clockwise with reference to FIG. 8, the pressure roller teeth 183, 186, 189 provided in each pressure roller 180, 185, 188 are The width of the pellet forming drum 133 from the first pressing roller 180 to the third pressing roller 188 along the rotation direction is provided in a form that gradually increases, the first pressing roller 180 in the third The pitch interval is gradually provided to the pressing roller 188 is reduced in form.

Thus, the width and pitch spacing of the pressure roller teeth 183, 186 (189) provided in each of the pressure rollers 180, 185, 188 are arranged in sequence along the rotation direction of the pellet forming drum 133. In other words, the injected pellet raw material can be more effectively pulverized by a plurality of press rollers 180, 185 and 188, and the pellet raw material can be more effectively indented into the forming hole 135 of the pellet forming drum 133. Can be. That is, when the pellet is manufactured, the pellet raw material introduced into the portion between the first press roller 180 and the third press roller 188 through the raw material input unit 107 is first rotated according to the rotation of the pellet forming drum 133. It is conveyed to the pressure roller 180 side. Since the pellet raw material can be more easily cut by the pressure roller teeth having a smaller width than the pressure roller teeth having a wide width, the pellet raw material conveyed to the first pressure roller 180 is relatively smaller in the first pressure roller 180. It can be smoothly crushed by the pressure roller tooth 183 of the.

The pellet raw material passed through the first press roller 180 is transferred to the second press roller 185 by the rotation of the pellet forming drum 133. The pellet raw material transferred to the second pressure roller 185 may be more finely crushed by the pressure roller tooth 186 provided in the second pressure roller 185. The pellet raw material passed through the second press roller 185 is transferred to the third press roller 188 in accordance with the rotation of the pellet forming drum 133. The pellet raw material conveyed to the third pressure roller 188 is pulverized more finely by the pressure roller teeth 189 provided in the third pressure roller 188 to be pressed into the forming hole 135 of the pellet forming drum 133. Can be. Since the pellet raw material can be pressed to the inner circumferential surface side of the pellet forming drum 133 more smoothly by a pressure roller tooth having a relatively wider width than the pressure roller tooth having a smaller width, it is more smoothly formed by the third pressure roller 188. It may be pressed into the hole 135.

The plurality of press rollers 180, 185 and 188 share their respective roles, and thus, the pellet raw materials are not crushed or pressed into the forming holes 135, but all have the same function, but as described above, each press By varying the width and pitch of the pressure roller teeth 183, 186, 189 provided in the rollers 180, 185, and 188, the injected pellet raw material is more effectively pulverized, and the pellet raw material is a pellet forming drum. It is possible to press more effectively into the forming hole 135 of the (133).

The specific configuration of the pressing rollers 180, 185, 188 is not limited to those shown. That is, the shape, width, and pitch spacing of the pressure roller teeth 183, 186, 189 provided in the pressure rollers 180, 185, and 188 may be variously changed without being limited to those shown. . In addition, the number or arrangement angle of the pressing rollers 180, 185 and 188 may also be variously changed.
