Hexagonal rotation guide roller (25a, 25b) is formed so as to move in contact with the node.

With reference to the accompanying drawings, the automatic coal boiler of the present invention configured as described above will be described in detail the operating state as follows.

In the automatic coal boiler of the present invention, as shown in FIG. 1, the coal is supplied to the crawler 20 inside the combustion chamber 10 through the coal hopper 33.

The coal discharged through the discharge port of the coal hopper 33 is supplied by its own weight through the coal hopper 33 when dragged along the movement of the crawler 20.

The thickness of the coal supplied and moved on the tracked portion 20 by the coal bed controller 47 is adjusted, and the coal bed controller 47 rotates the coal bed control knob 19 and the coal hopper 33. When the coal discharged through the bed is moved along the tracked portion 20, the coal of the upper side of the coal being stacked and moved can not be moved, so that the thickness of the coal can be adjusted.

Rotating the coal bed control knob 19 controls the thickness of the coal moved along the track 20, while the coal bed regulator 47 interlocked at this end is lowered or raised toward the crawler 20 side. Done. That is, when the coal supplied on the coal hopper 33 is piled up and moved while being fed and stacked on the tracker 20 by the height adjustment of the coal bed regulator 47, the accumulated coal collides with the coal bed regulator 47 and falls. Due to the coal moving on the tracked portion 20 is stacked and moved only by the height of the coal bed regulator 47 can adjust the amount of coal movement.

An ember observation port 29 is formed in the side surface of the combustion chamber 10 so that the combustion state of the coal moving along the caterpillar 20 can be seen inside the combustion chamber 10 of the main body 40. Can be observed.

Coal moved to the center of the combustion chamber 10 along the crawler 20 is combusted while moving toward the center of the combustion chamber 10.

The tracked portion 20 is caught and rotated by the sprockets 22 and 24 formed at both ends of the inner side of the combustion chamber 10, among which the sprocket 22 is rotated by the drive motor 26. Is rotated.

In addition, when the rotation of the crawler 20 is caught by the sprockets 22 and 24, the hexagon guide rollers 25a and 25b formed on the outer side of the sprockets 22 and 24 are thus rotated. Is rotated while being guided by). That is, the outer circumferential diameters of the hexagon guide rollers 25a and 25b are hexagonal, and the nodes of the hexagon guide rollers 25a and 25b are the coal seating portions 21 of the crawler portion 20. It is guided and rotated.

Therefore, when the sprockets 22 and 24 and the hexagonal guide rollers 25a and 25b formed on the outer side thereof are rotated, the knurled portion of the angled outer diameter is the same as the size of the coal seat 21, so that the coal is rotated. The seating portion 21 is characterized by moving one by one.

By this operation, the coal moved on the coal seating portion 21 of the crawler 20 is moved in a ignited state. That is, since the coal supplied to the crawler 20 is continuously supplied in a stripe shape on the crawler 20 so as to be continuously burned, the combustion continues continuously.

The coal located at the end of the track 20, which hangs on the sprocket 24 of the coal burned while moving along the coal seating portion 21 of the track 20, is moved to the re-recycle bin 12 on the lower side. Are collected apart.

In this way, the burnt coal ash collected in the recycling container 12 may be taken out of the combustion and then emptied again and then put again.

The high speed blower 30 is connected to move along the communication 16, and is connected to the end end side of the communication 16 so as to be supplied to the ascending air supply unit 14 so that the coal seat 21 on the crawler 20 is provided. Blows air onto the coal burning in

At this time, the external air supplied to the rising air supply unit 14 is supplied by the high speed blower 30 installed on the side of the main body 40 and at the same time the air is also lowered at the upper end of the orbit by the lower air supply unit 17. Infuse

In this way, since the air can be strongly blown into the coal combusted on the coal seat 21 on the crawler 20 by the rising air supply unit 14 and the falling air supply unit 17, the high-power blower 30 You can increase or decrease the firepower by adjusting the amount of air supplied from the unit.

When coal is burned along the endless track 20 in the combustion chamber 10, the heat of combustion naturally rises and is supplied to the heat exchanger 50 on the upper side.

The heat of coal that is burned by the inner heat exchanger part 50 of the main body part 40 flows along the heat exchange pipe 56 through which the heat exchanger water supplied through the water inlet 52 flows.

The heat exchange pipe 56 is formed to be layered at regular intervals in order to increase the heat exchange efficiency to conduct the coal heat of the combustion chamber 10 therebetween.

At this time, the combustion heat of the coal contacted with the heat exchange pipe 56 is conducted to the heat exchange pipe 56 to heat the heat exchange water passing through the heat exchange pipe 56.

In this way, the water warmed while passing through the heat exchange pipe 56 is discharged to the water outlet 54 and the vinyl house is supplied to the floor pipe or the radiator to be heated.

The heat of combustion of the coal passing between the heat exchange pipes 56 formed in the heat exchange unit 50 in a layered manner is discharged to the outside through the air outlet 58.

In the heat exchange part 50 formed on the upper side of the combustion chamber 10, the heat-absorbing / heat-dissipating plate 60, 62 is formed in two stages between the heat-exchanging pipes 56 formed in a layered manner so that the heat of combustion is immediately vertical. It is configured to return to the S-shape without being discharged to increase the heat efficiency of the combustion heat of the coal in the heat exchange unit 50 to increase the thermal efficiency.

In addition, the endothermic / heat sink 60, 62 absorbs the heat of combustion of coal initially generated and continues to absorb the heat absorbed by the endothermic / heat sink 60, 62 for a predetermined time even when the combustion of coal is stopped. Since the heat is emitted into the heat exchanger 50, the heat exchanged in the heat exchange pipe 56 is characterized in that the cool gradually without dropping.

In addition, the endothermic / heat-dissipating plate (60), 62 is the heat that is burned when the coal on the coal seat 21 of the trackless portion 20 is burned directly heat exchange pipe (56) of the heat exchange unit (50) It can be blocked so as not to close the can extend the life of the heat exchange pipe (56).

Since the endothermic / heat sink 60 and 62 are formed to be inclined to one side, when coal ash is blown up to the upper side of the heat exchanger 50, the heat sink / heat sink 60 and 62 sinks to the upper side of the endothermic / heat sink 60 and 62. It is rolled down and discharged to the recleaning ports 63 and 64 formed at the end thereof.

At this time, since the re-cleaning mouths 63 and 64 do not have a large amount of coal ash, the re-removal of the ashes 63 and 64 is carried out along the endothermic / heat-dissipating plate 60 and 62 by setting a periodic time. It can be discharged after opening.

As shown in FIG. 3, the automatic coal boiler according to the present invention includes an induction plate temperature sensor 59 capable of measuring the temperature of coal heat burned on the coal seat 21 of the crawler 20 inside the combustion chamber 10. By controlling the rotational force of the drive motor 26 can be adjusted the moving speed of the coal.

In addition, the heat exchanger 50 heated by the coal heat of the combustion chamber 10 is checked by using a water temperature sensor 57 to check the temperature of the water heated while passing through the heat exchange pipe 56.

When the temperature of the heat exchanger 50 is lowered by the water temperature sensor 57 as described above, the high speed blower 30 is operated to help the combustion of coal heat to increase the thermal power.

The heat exchanger 50 has a low water level sensor 55 that can be checked to ensure that the heat exchange water is always filled, so that not only an appropriate amount can be maintained at all times, but also the low water level sensor 55 of the heat exchanger 50 When the water level is lowered, this can be detected and a warning sound can be generated through the alarm buzzer 39 by the signal value set in the main controller 80.

That is, the present invention, as shown in Figure 3, the automatic coal boiler is automatically controlled by the control value set by the main controller 80.

The temperature of coal burnt on the track 20 in the boiler combustion chamber 10 of the present invention is transmitted to the signal processor 70 by an analog signal sensed by the platen temperature sensor 59.

When the analog signal received by the signal processing unit 70 is converted into a digital signal and then transmitted to the main control unit 80, the main control unit 80 uses the received signal to set the signal according to the signal value set in the main control unit 80. The drive motor 26 is driven.

As such, while the rotational force of the driving motor 26 is controlled, the amount of coal moved can be adjusted, and at the same time, the coal heat burned can also be controlled.

In addition, the water temperature sensor 57 mounted on the heat exchanger 50 detects the temperature of the water warmed inside and transmits the detected analog signal to the signal processor 70 and converts it into a digital signal. The main controller 80 thereby operates the high speed blower 30.

That is, the high speed blower 30 operated by the water temperature sensor 57 stops the high speed blower 30 when the temperature is 5 ° C. or more above the set temperature by using the signal value set in the main controller 80, and generally coal The natural combustion state is maintained, and when the temperature is -10 ° C or more lower than the set temperature, the high speed blower 30 is operated to increase the combustion of coal.

The analog signal based on the temperature of the water detected by the water temperature sensor 57 of the heat exchanger 50 converts the signal received from the signal processor 70 into a digital signal, and then transmits the signal to the main controller 80 to transmit the digital signal to the main controller 80. In response to the digital signal, which is the water temperature, is compared with the signal value set in the main controller 80, the circulation pump 34 is operated when the boiler is over the set temperature, and when the temperature falls below the set temperature, the circulation pump 34 ) Is stopped.

The circulation pump 34 may be mounted on either the water inlet 52 or the water outlet 54 of the heat exchanger 50, but is preferably mounted and operated at the water inlet 52 side.

This is because when the circulation pump 34 is mounted on the water outlet 54 side of the heat exchanger 52, a problem may occur that increases the heat in the pump itself that is operated because the temperature of the hot water discharged is high. It is good to be mounted on the water inlet 52 side through which the low temperature returning water flows.

The analog low water level signal sensed by the low water level sensor 55 is transmitted to the signal processor 70.

The signal sensed by the low water level sensor 55 is converted into a digital signal through the signal processor 50 and then forcibly stops the high speed blower 30 at the low water level by using the signal value set by the main controller 60. Alarm sound is generated through the alarm buzzer 39 to prevent overheating of the heat exchange part 2.

As shown in FIG. 4, the coal seating portion 21 formed of the node of the crawler portion 20 of the present invention is bent toward the upper side and protrudes from the rear side of the coal seating portion 21. It is configured to be folded in shape.

The coal seating portion 21 configured as described above is formed so that the rear end portion of the moving portion protrudes toward the upper side to prevent the coal from falling out between the chains connected to the rear side, and the front end portion of the moving direction is bent by a curved shape. It is configured to prevent the coal from falling between connected to the city, the node of the coal seating portion 21 is closely connected to prevent the coal from falling between the connecting portion.

Therefore, an automatic coal boiler capable of automatically burning low-cost coal so as to raise the indoor temperature in order to prevent the east sea of crops grown indoors such as a vinyl house by the automatic coal boiler of the present invention as described above. In providing.
