Description

FIELD OF THE INVENTION [0001] The present invention relates to a fuel pellet manufacturing apparatus,

The present invention relates to an apparatus for producing pellets for fuel, and more particularly, to a pellet making apparatus for fuel, which can be reduced in size and weight with a relatively simple structure as compared with the conventional pelletizing apparatus, The present invention relates to an apparatus for producing pellets for fuel.

In general, boilers are used not only for heating of houses or public facilities but also for industrial use. Generally, oil or gas is used as fuel for these boilers. In this case, the boiler is usually equipped with a temperature control device and is configured so that oil or gas is automatically supplied to the combustion chamber so as to meet the set temperature, and is used as a power source for heating and industrial facilities through combustion heat generated as fuel is ignited.

On the other hand, oil or gas as a raw material of the boiler as described above is widely used as a raw material for a boiler because it is easy to manage fuel injection and temperature control, and high combustion heat can be obtained. However, And since the heating cost is increased due to a large amount of fuel, the combustion gas is not only economically burdened but also the combustion gas discharged during combustion destroys the environment by polluting the atmosphere.

Accordingly, as described above, there is a tendency that boilers using wood, which is relatively cheap compared to boilers using oil or gas, are being used. Boilers using such wood can be said to be more environmentally friendly than oil or gas as well as reduce heating costs.

In addition, due to the desire to escape from urban life and naturalize to nature, the power house has been activated, and the spread of heating stoves made of wood as a raw material has spread widely. Furthermore, the use of wood-based boilers is increasing as a method for heating the inside of a vinyl house in an agricultural method of cultivating various fruits and vegetables using a vinyl house.

However, as described above, the method using wood is advantageous in that it can reduce fuel cost compared with oil or gas, but it has a disadvantage in that thermal efficiency is lower than that of oil or gas. Of course, It is very difficult to supply them to the apparatus. Moreover, there is a troublesome problem because the user must continuously manually remove the combustion waste generated when the wood is burned.

Therefore, in recent years, techniques for producing pelletized solid fuel using sawdust have been developed and used with the aim of replacing fossil fuels and rediscovery of wood resources. Since such pelletized wood fuel is produced by compression, it is very economical in terms of heat generation and thermal efficiency for a long time.

However, the conventional apparatus for manufacturing wood pellets is not only very bulky, but also has a large noise and relatively long manufacturing time, which is difficult from the viewpoint of cost and facility area.

At this time, the rotation drive control block may be provided with a scale indication including a reference scale and a control scale for indicating gap adjustment.

Subsequently, the outer housing 500 housing the pelletizing drum unit 300 receives the pelletizing drum unit and is configured to communicate with a pellet feeder unit 600 described later, A reservoir for receiving and storing the pellets, which are consolidated from the unit, may be formed.

The present invention is characterized in that the present invention is constituted to extend from the outer housing 500 toward the forming drum 310 so that the pellet can be cut out from the pellet forming hole 311 of the forming drum 310 (Not shown).

When the pellets are compressed to a predetermined length, the pellets can be cut while being randomly boiled. The pellets of a certain length can be provided by forming the cutting blades in the outer housing 500.

At this time, the cutting blade may be configured such that the degree of protrusion of the cutting blade from the outer housing 500 is adjustable. This adjusts the length of the pellet being cut.

Next, a pellet feeder unit 600 for feeding the pellet feed into the pelletizing drum unit 300 is composed of a hopper part having an upper hopper shape, and extends from the hopper part to form the pelletizing drum unit 300 to the inside of the forming drum 310.

The operation of the fuel pellet manufacturing apparatus according to the present invention will now be described.

The rotational driving force of the driving motor 100 is transmitted to the reduction gear unit 200 and the rotational force decelerated from the reduction gear unit 200 is transmitted to the forming drum 300 of the pelletizing drum unit 300, (Not shown).

The pressing roller 440 of the pressing unit 400 fixed to the inside of the forming drum 310 presses the pellet raw material introduced into the forming drum 310 in the process of rotating the forming drum 310 And the compacted pellet is discharged from the pelletizing hole 311 formed in the forming drum 310. [

Here, the gap between the forming drum 310 and the pressing roller 440 can be finely adjusted through adjustment of the gap adjusting means, thereby adjusting the degree of compression of the pellet that is produced through consolidation.
