On the other hand, the present invention may be variously modified and may take various forms in applying the above configuration.

And it is to be understood that the invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood that.

Referring to the effect of the heat source recovery apparatus according to the combustion of the solid fuel of the present invention configured as described above are as follows.

In the present invention, when various solid fuels (firewood, charcoal, coal, briquettes, coke, wood, paper, etc.) are automatically injected into the combustion chamber 71 and ignited, a heat source is generated in the combustion chamber 71. It is designed to be used for cooling, heating and hot water of factories, buildings, houses, etc., and to use cooling, heating, and hot water using solar heat.

First, when each of the driving chains 55a, 55b, 55c is driven by the driving of the first driving motor 55, the fuel supply unit 50 and the fuel transfer unit 60 operate together.

The fuel supply unit 50 transports the solid fuel (firewood, charcoal, coal, briquettes, coke, wood, paper, etc.) of the supply box 51 and transfers it to the upper portion and then inputs the hopper 56.

The solid fuel introduced into the hopper 56 is introduced into the fuel box 61 of the fuel transfer unit 60 to be transferred to one side.

In this case, as shown in FIG. 4, the pushing plate 64, which is a space forming unit 63 connected between the fuel boxes 61, is in close contact with the curved section, and the pushing plate 64 is located on the horizontal line. As it is pushed to one side, the solid fuel is pushed to one side to form a space.

That is, in the curved section, the pusher plate 64 is opened so that the fuel tank 61 is in close contact with the fuel tank 61, and on the horizontal line, the distance between the fuel tank 61 and the fuel tank 61 is narrowed, so that it is relatively fixed. One side of the non-smiling plate 64 pushes the solid fuel to one side, thereby forming a space, and thus, the air smoothly flows into the bottom through-hole 62 to help the combustion of the solid fuel as described below.

On the other hand, the various solid fuel introduced into the fuel box 61 is introduced into the combustion section 70 and then burned by the heat source generated in the combustion chamber 71.

That is, when the solid fuel flows into the combustion chamber 71, the ignition unit 80 operates to combust the solid fuel. As shown in FIG. 6, the fuel in the fuel container 83 is connected to the fuel compression pump 84. By operation, it flows into the spark plug 81 and the fuel thus injected is ejected through the nozzle 82. In the present invention, a high voltage is generated at the ignition coil 81a provided at the tip of the spark plug 81 to generate a spark, and the spark generated thereby burns the solid fuel.

In the present invention, when the temperature is higher than the set temperature in the process of burning the solid fuel by the spark plug 81, the high temperature sensor 86 sends a signal to the optical sensor 87 to stop the operation of the ignition unit 80. On the contrary, when the temperature is lower than the set temperature, the low temperature sensor 85 sends a signal to the optical sensor 87 to operate the ignition unit 80.

In addition, the inside of the combustion chamber 71 is blown to the upper by operating the blower fan (70a) to maximize the combustion effect, when the operation of the blower fan (70a) the door 73 of one side is raised On the contrary, when the blowing fan 70a does not operate, the door 73 descends to close the inlet.

When the blower fan 70a stops and the door 73 descends to close the combustion chamber 71, the combustion blocking unit 78 descends by driving of the second driving motor 79 to block oxygen. In this case, when the temperature rises above the set temperature or stops the combustion as necessary, the combustion blocking unit 78 covers the fuel box 61 to block oxygen to stop the system.

In the process of operating the combustion unit 70 as described above, the heat source recovery unit 90 attached to the outer circumferential surface of the combustion chamber 71 at predetermined intervals receives and accumulates the heat source generated in the combustion process, and then cools, heats, and warm water. The role of supply is to produce a particularly high instantaneous heat.

That is, as shown in FIG. 5, when the hydraulic oil is introduced into the hydraulic oil inlet 94, the hydraulic oil flows into the inner mesh 95 of the heat insulating part 91, absorbs heat from the evaporator 92, and then reconnects the mesh 92. In order to radiate heat from the final condensation unit 93 to the outside, the operation is repeated so that the heat source is collected, and the final collected heat serves to use cooling, heating, or hot water.

On the other hand, the present invention as well as to obtain a heat source by the combustion of the solid fuel as described above, of course, it is also possible to obtain a heat source using solar heat.

That is, as shown in FIG. 3, the solar heat passes through the inner transparent plate 76 and the outer transparent plate 77 provided on the outer circumferential surface of the combustion chamber 71, and then is transferred to the heat source recovery unit 90 to accumulate solar heat. As such, the reason why the solar heat is transmitted to the heat source recovery unit 90 is possible because it is formed of a transparent plate, and the heat source recovery unit 90 integrating the solar heat as described above maintains high temperature so that cooling, heating, or hot water is performed. It will serve to supply.

In addition, the air layer 76a provided between the combustion chamber 71 and the inner transparent plate 76 serves to prevent a heat source from being transferred to the outside of the inner transparent plate 76, and also the inner transparent plate 76. And the vacuum layer 77a provided between the outer transparent plate 77 prevent the heat source of the combustion chamber 71 from being transmitted to the outside.

In addition, in the present invention, since the filter of the air purification unit 72 is filtered in the process of discharging the fine dust generated in the combustion chamber 71 to the outside to remove the dioxins and various air pollutants.

The present invention is also capable of maximizing thermal efficiency by the curved portion 71a protruding into the combustion chamber 71 and the heat source recovery portion 90 provided in the curved portion, which is located at the upper end of the ignition portion 80. Since the heat source recovery portion 90 of the curved portion 71a receives heat directly, heat can be accumulated as much as it is, thereby obtaining high efficiency.

Meanwhile, in the present invention, heat is prevented from being discharged to the outside by the first inlet blocking membrane 66a provided at the inlet of the combustion chamber 71, and the second inlet blocking membrane 66b provided at the outside of the combustion chamber 71 is The heat source discharged away from the first inlet blocking membrane 66a may be prevented secondarily.

According to the present invention, heat is prevented from being discharged to the outside by the first outlet blocking film 67a provided at the outlet of the combustion chamber 71, and the second outlet blocking film 67b provided at the outside of the combustion chamber 71 It is possible to prevent the heat source discharged away from the first outlet blocking membrane 67a to be secondary, and the blocking membranes are freely rotated about the hinge axis so that the progress of the fuel box 61 is not hindered.

The present invention can completely remove the flame of the solid fuel discharged through the combustion unit 70 as described above, the water is sprayed from the upper water spraying unit 100 just before the ash of the solid fuel is discharged to the collector 53 This will completely remove the embers left in the solid fuel.

As described in detail above, the present invention is provided with a fuel transfer unit, a combustion unit, an ignition unit, and a heat source recovery unit. In particular, when the various solid fuels are automatically put into the combustion chamber and ignited by the above technical configuration, This heat source is recovered and used for cooling, heating, and hot water in factories, buildings, and houses. As a result, the solid fuel has a high calorific value, which is excellent in thermal efficiency and complete supply of oxygen. It enables the combustion to remove air pollutants such as carbon monoxide and dioxin, and to produce high heat instantaneously. This greatly improves the quality and reliability of the product, and gives users a good image. It is a very useful invention.
