TECHNICAL FIELD

[0001] The present application relates to the field of charcoal roasting, in particular to a ground cage type charcoal roasting device. BACKGROUND

[0002] At present, when roasting charcoal, civil charcoal roasting kiln is usually used, which heats wood in an oxygen-deficient environment to make it undergo pyrolysis reaction, thereby removing water, volatile and other impurities in the wood, and finally obtaining charcoal. However, this method has many problems, only low-temperature carbon can be roasted, high-temperature carbon cannot be roasted, and the carbon yield is low, and uncooked carbon is also easy to produce.

[0003] Through retrieval, it is known that in the prior art, for example, patent CN201920395986.5 discloses a charcoal roasting kiln, which comprises a furnace body, a furnace cover, a heating pump and a plurality of temperature monitors. The side wall of the furnace body is provided with an exhaust port and a plurality of air inlets, the exhaust port is located at the upper middle part of the furnace body, and the air inlets are close to the bottom of the furnace body; the furnace cover is movably installed on the top of the furnace body; the heating pump heats the inside of the furnace body near the bottom of the furnace body; the temperature monitors are distributed on the side wall of the furnace body and the furnace cover, and are used to monitor the temperature inside the furnace body. The above-mentioned charcoal roasting kiln still has the following defects in actual application:

[0004] The heating pump is located at the bottom of the furnace body for heating, which is easy to cause the temperature of the bottom to be too high and the temperature of the upper part to be relatively low; the heat distribution may have gradient difference, in the roasting process, the charcoal at the bottom may be carbonized too fast due to the too high temperature, and even be burned too much, while the charcoal at the upper part may not reach the ideal carbonization temperature, thereby affecting the overall quality of the charcoal; and the sealing property is difficult to reach the ideal state, in the roasting process, heat may be lost from the gap between the furnace cover and the furnace body, and cold air from outside may also enter the furnace, interfering with the internal temperature and further reducing the energy utilization efficiency. CONTENT OF THE UTILITY MODEL

[0005] In order to solve the problems existing in the prior art, the present application aims to provide a ground cage type charcoal roasting device. The ground cage type charcoal roasting device is arranged below the ground by arranging the fuel flow channel and the carbonization kiln below the ground. Since the heat conduction of the underground environment is relatively stable, compared with the kiln above the ground, the surrounding soil can be used as a natural heat insulation and heat equalization medium. When the fuel passes through the fuel flow channel and enters the carbonization kiln and burns, the heat will uniformly spread in the carbonization kiln, making the temperature distribution in the carbonization kiln more uniform, which helps to ensure that the charcoal in the roasting process can be subjected to relatively consistent temperature action at each part, reducing the uneven quality of the charcoal caused by temperature difference.

[0006] The charcoal roasting device comprises a fuel supply assembly, at least one fuel flow channel and at least one carbonization kiln.

[0007] The fuel flow channel is in communication with the fuel supply assembly, and the carbonization kiln is in communication with the fuel flow channel.

[0008] Preferably, a plurality of carbonization kilns are arranged adjacent to each other along the flow path of the fuel flow channel, forming a row of carbonization kilns, and the axis of each carbonization kiln is perpendicular to the flow path of the fuel flow channel.

[0009] Preferably, each fuel flow channel is provided with a row of carbonization kilns on both sides of the flow path, and the two rows of carbonization kilns are arranged oppositely.

[0010] Preferably, the carbonization kiln comprises a combustion cavity opened below the ground surface and a sealing cover installed on the upper end of the combustion cavity, and the combustion cavity is used for placing raw materials for roasting charcoal.

[0011] Preferably, each carbonization kiln is provided with an air inlet at one end close to the fuel flow channel, and the fuel flow channel is in communication with the carbonization kiln through the air inlet, and the fuel flowing through the fuel flow channel is introduced into the combustion cavity through the air inlet.

[0012] Preferably, each carbonization kiln is provided with an oxygen inlet at one end away from the fuel flow channel, and oxygen is introduced into the combustion cavity through the oxygen inlet.

[0013] Preferably, the charcoal roasting device further comprises a fuel recovery assembly in communication with the discharge end of the fuel flow channel.

[0014] Preferably, the fuel supply assembly stores carbonization gas, and the fuel supply assembly provides the carbonization gas to the fuel flow channel through the inlet end.

[0015] The charcoal roasting device has the following advantages:

[0016] The present application discloses a ground-cage type charcoal burning device, which includes a fuel supply component, at least one fuel channel and at least one carbonization kiln located below the ground surface; the feed end of the fuel channel is connected to the fuel supply component, and the carbonization kiln is connected to the fuel channel. By placing the fuel channel and carbonization kiln underground, the relatively stable heat conduction of the underground environment allows the surrounding soil to serve as a natural insulation and heat equalization medium, compared to kilns above ground. When fuel is introduced into the carbonization kiln through the fuel channel and burned, heat is evenly diffused within the kiln, resulting in a more uniform temperature distribution. This helps ensure that all parts of the charcoal receive a more consistent temperature during the firing process, reducing uneven charcoal quality caused by temperature differences. Since soil is an excellent insulation material, the carbonization kiln, surrounded by soil, effectively reduces heat loss. The heat generated by fuel combustion is well preserved in the underground space. Compared to kilns above ground, it is not necessary to frequently replenish heat to maintain the firing temperature. This allows for more efficient use of the heat generated by fuel combustion during charcoal firing, thereby improving energy efficiency and reducing fuel costs. Attached Figure Description

[0020] 20 - Fuel flow path;

[0021] 30 - Carbonization kiln; 301 - Air inlet; 302 - Oxygen supply port. Detailed Implementation

[0022] like Figure 1 As shown, the ground cage type charcoal burning device described in this application includes a fuel supply component 10, at least one fuel flow channel 20 opened below the ground surface, and at least one carbonization kiln 30; the fuel supply component 10 stores fuel for burning charcoal, and the fuel supply component 10 supplies fuel to the fuel flow channel 20, and the fuel flows in the fuel flow channel 20.

[0023] The feed end of the fuel flow channel 20 is connected to the fuel supply component 10, and the carbonization kiln 30 is connected to the fuel flow channel 20. Specifically, the flow path of the carbonization kiln 30 and the fuel flow channel 20 is connected, so that the fuel in the fuel flow channel 20 can enter the carbonization kiln 30 when it flows.

[0024] By arranging the fuel flow channel 20 and the carbonization kiln 30 below the ground surface, the surrounding soil can be used as a natural heat insulation and heat equalization medium due to the relatively stable heat conduction of the underground environment. When fuel is introduced into the carbonization kiln 30 through the fuel flow channel 20 and burns, the heat will spread evenly within the carbonization kiln 30, making the temperature distribution within the carbonization kiln 30 more uniform. This helps to ensure that the charcoal is subjected to a relatively consistent temperature throughout the entire burning process, reducing the likelihood of uneven charcoal quality caused by temperature differences. Since soil is a good heat insulation material, the carbonization kiln 30 is surrounded by soil, which effectively reduces heat loss. The heat generated by fuel combustion is well preserved in the underground space, eliminating the need for frequent replenishment of heat to maintain the burning temperature. This allows for more efficient use of the heat generated by fuel combustion during the charcoal burning process, thereby improving energy utilization efficiency and reducing fuel costs.

[0025] Further, in the present embodiment, a plurality of carbonization kilns 30 are arranged adjacent to each other along the flow path of the fuel flow channel 20, forming a row of carbonization kilns 30, and the axis of each carbonization kiln 30 is perpendicular to the flow path of the fuel flow channel 20.

[0026] Further, in the present embodiment, each fuel flow channel 20 has a row of carbonization kilns 30 arranged on both sides of the flow path, and the two rows of carbonization kilns 30 are arranged opposite to each other; that is, the two rows of carbonization kilns 30 corresponding to the two sides of the fuel flow channel 20 are arranged opposite to each other, and the carbonization kilns 30 on both sides of the flow path are in communication with the fuel flow channel 20.

[0027] Further, in the present embodiment, the carbonization kiln 30 includes a combustion cavity arranged below the ground surface, and a sealing cover installed on the upper end of the combustion cavity, the combustion cavity being used to place raw materials for burning charcoal;

[0028] The combustion cavity has an opening facing the direction above the ground surface, and the raw materials for burning charcoal are placed inside the combustion cavity through the opening, and then the sealing cover is installed on the opening to cover the opening on the upper end of the combustion cavity;

[0029] The raw materials for burning charcoal include wood and a small amount of charcoal placed at the bottom of the combustion cavity. Since the ignition point of wood is relatively high in the initial stage of burning charcoal, it may be difficult to ignite the wood directly. The small amount of charcoal placed at the bottom of the combustion cavity can serve as a fire starter because the ignition point of charcoal is lower than that of wood. The combustion of wood may be unstable due to factors such as humidity and density, resulting in fluctuations in heat generation. The combustion of charcoal is relatively stable and can release heat before or during the initial stage of wood combustion, helping to maintain the temperature inside the combustion cavity and allowing the temperature to quickly rise to a range suitable for wood drying and pyrolysis.

[0030] Further, in the embodiment, each carbonization kiln 30 is provided with an air inlet 301 at one end close to the fuel flow channel 20, and the fuel flow channel 20 is communicated with the carbonization kiln 30 through the air inlet 301, and the fuel flowing through the fuel flow channel 20 is introduced into the combustion chamber through the air inlet 301.

[0031] Further, in the embodiment, each carbonization kiln 30 is provided with an air inlet 301 at one end close to the fuel flow channel 20, and the fuel flow channel 20 is communicated with the carbonization kiln 30 through the air inlet 301, and the fuel flowing through the fuel flow channel 20 is introduced into the combustion chamber through the air inlet 301.

[0032] By introducing an appropriate amount of oxygen into the combustion chamber through the oxygen inlet, the fuel can be in contact with oxygen, so that a more complete oxidation reaction can be carried out, and complete combustion can be carried out; and the introduction of oxygen can make the wood burn fully and release more heat, which helps to maintain a stable and high enough temperature in the carbonization kiln 30, which is very critical for efficient charcoal burning; the specific amount of oxygen introduced is selected according to the actual situation.

[0033] Further, in the embodiment, the ground cage type charcoal making device further comprises a fuel recovery assembly, which is communicated with the discharge end of the fuel flow channel 20; that is, most of the fuel flowing through the fuel flow channel 20 is introduced into the carbonization kiln 30, but part of the fuel does not flow into the carbonization kiln 30 and flows to the discharge end of the fuel flow channel 20, and the fuel recovery assembly is communicated with the discharge end of the fuel flow channel 20 to recover and process the fuel that is not used in the carbonization kiln 30.

[0034] If the fuel that is not used in the carbonization kiln 30 is directly discarded, it will cause waste of resources, and by recovering the fuel through the fuel recovery assembly, the fuel can be reused in the charcoal making process, thereby improving the overall utilization rate of the fuel; to a certain extent, the production cost is reduced, and the economic benefit is improved; and if the unused fuel is not recovered, the unused fuel will be treated as waste, which may accumulate and rot in the natural environment, or produce a large amount of harmful gas and dust in the process of improper combustion (such as open-air burning), and by recovering the fuel, the amount of waste generated is reduced, and the pollution risk to the surrounding soil, water and atmospheric environment is reduced.

[0035] Further, in the embodiment, the fuel supply assembly 10 stores carbonization gas, and the fuel supply assembly 10 provides the carbonization gas to the fuel flow channel 20 through the feed end; the carbonization gas can be carbon monoxide.

[0036] The working process of the ground cage type charcoal making device of the embodiment will be described in detail below in combination with the above.

[0037] The embodiment takes two fuel flow channels 20 as an example, and each fuel flow channel 20 has a row of carbonization kilns 30 on both sides of the flow path.

[0038] Firstly, the sealing cover corresponding to each carbonization furnace 30 is taken out, and the raw material for burning charcoal is put into the combustion cavity through the opening of the combustion cavity, including wood and a small amount of charcoal placed at the bottom of the combustion cavity. After the placement is completed, the sealing cover is installed at the opening of the combustion cavity to isolate air from entering the inside of the combustion cavity.

[0039] Then, the fuel supply assembly 10 provides fuel to the fuel flow channel 20, and the fuel is carbonization gas, so that the carbonization gas flows along the flow path of the fuel flow channel 20, that is, from the inlet end of the fuel flow channel 20 to the outlet end in the direction of the flow path.

[0040] Then, the carbonization gas flowing in the flow path of the fuel flow channel 20 enters the combustion cavity through the gas inlet of the carbonization furnace 30, and the appropriate amount of oxygen is introduced through the oxygen supply port of the carbonization furnace 30, so that the small amount of charcoal placed at the bottom of the combustion cavity starts to burn, and then the wood in the combustion cavity is burned.

[0041] Finally, after a period of burning, the charcoal is burned, and since the charcoal is burned in the carbonization furnace 30 below the ground, the surrounding soil can be used as a natural heat insulation and heat equalization medium during the charcoal burning process, and heat loss can be effectively reduced. Compared with using above-ground furnaces for burning, the burning time can be greatly shortened.
