Description

Technical Field

[0001] The utility model belongs to the field of stoves, and in particular relates to a dry distillation gasification stove for burning cow dung and sheep dung in all seasons. Background Art

[0002] A combustion furnace is an instrument that converts the energy of fuel into heat energy under the condition of oxygen through combustion. Nowadays, gas projects are connected to thousands of households, but in many remote areas, especially in northern Tibet, due to the difficulty in implementing HVAC projects, the ancient plateau combustion furnaces are still used for cooking and boiling water, and the heat emitted by its own structure can also be used for heating. Due to the harsh environment in high altitude areas, ordinary fuels are not only expensive but also difficult to obtain, while cow dung is easy to obtain, so most of the combustion furnaces use cow dung as the main raw material.

[0003] However, using cow dung, sheep dung, etc. as fuel will cause the following problems:

[0004] 1. Cow dung and sheep dung are not dry enough, the combustion is not complete, and the utilization rate is low;

[0005] 2. Cow dung and sheep dung are not easy to burn, and if they are not burned completely, they will produce a lot of smoke and pollute the environment. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model aims to provide a universal dry distillation gasification stove for burning cow dung and sheep dung in all seasons, and solves the above problems by changing the stove.

[0007] In order to solve the above problems existing in the prior art, the technical solution adopted by the utility model is:

[0008] A universal dry distillation gasification stove for burning cow dung and sheep dung in all seasons, comprising a stove body, wherein the stove body is divided into a material storage chamber, a combustion chamber, a heating chamber and a heat dissipation chamber;

[0009] A grate is provided at the lower part of the storage chamber, and the storage chamber is connected with a coke cleaning port and a secondary air distribution port;

[0010] A reverse burning plate is provided between the combustion chamber and the material storage chamber, and the reverse burning plate is provided with three air distribution ports;

[0011] Four air distribution ports are provided between the heating chamber and the combustion chamber;

[0012] The heat dissipation chamber is connected with an exhaust pipe, an adjustable fire sealing component is arranged between the heat dissipation chamber and the combustion chamber, and a water heating switching plate is arranged between the heat dissipation chamber and the heating chamber.

[0013] The four air distributions have their own characteristics. In addition to supporting combustion, they also have the following functions:

[0014] 1. The charging port is also the secondary air distribution port. The secondary air at the charging port solves the problem that the silo door cannot be opened due to long-term fire blocking and tar in the storage silo adhering to the silo door.

[0015] 2. The three-wind system at the cavity-type back-burning plate solves the problem of short life of the back-burning plate in the high-temperature area. At present, the back-burning plates of the barbecue stoves on the market are all single-layered, and the back-burning plates will carbonize and delaminate during combustion.

[0016] Furthermore, the middle portion of the anti-burning plate protrudes toward the combustion chamber.

[0017] The anti-burning plate is in the shape of “>”.

[0018] The tertiary air distribution port is arranged on the anti-firing plate, and the tertiary air distribution port is connected to the outside of the furnace body through the tertiary air inlet channel.

[0019] The tertiary air distribution port is mainly used to provide fresh air to the burning fuel, and the quaternary air distribution port is mainly used to provide fresh air to the burning flame.

[0021] 1. The “>” type cavity anti-burning plate increases the volume of the storage cavity because its middle part protrudes toward the combustion cavity. The storage cavity is used for burning materials, thus increasing the capacity of the silo.

[0022] 2. The dry distillation area is increased (the dry distillation area refers to the storage cavity), which can burn fuels with high humidity and fuels with humidity within 30%.

[0023] 3. The air velocity at the closing part of the “>” structure (the bottom of the anti-burning plate) is high, which can make the combustible gas and the tertiary and quaternary air intakes fully mixed. The flame temperature is high and the energy-saving effect is obvious. The heating and cooking effects are good, and the water boiling and cooking can be comparable to liquefied gas.

[0024] 4. When the fuel is burning, the burning speed is fast at the throat (bottom) of the anti-burning plate. The fuel at the slope of the “>” structure slides down to the throat under the action of gravity to replenish the cavity produced by the combustion. (Other manufacturers use straight anti-burning plates that cannot replenish the combustion cavity at the throat well).

[0025] Furthermore, the lower part of the material storage chamber is connected to the lower part of the combustion chamber. The upper part of the material storage chamber is connected to the combustion chamber through an overflow hole. A combustible gas overflow hole is added to the material storage bin.

The water-heating component is detachably connected to the furnace body, and the water-heating component can be disassembled during actual use. Independently removable water-heating heating body. Since cattle and sheep manure contains high humidity and highly corrosive acidic substances, and the water-heating part is more susceptible to corrosion due to the low temperature, the removable water-heating heating body can also be replaced by the user. The water-heating component extends into the furnace body and is connected to the furnace body through the water-heating shells on both sides. The water-heating pipe is directly connected to the external heating pipeline to realize water-heating heating. There is a hollow structure between the two water-heating shells, and only the water-heating pipe passes through it to facilitate the circulation of heat.

[0027] Furthermore, the adjustable fire sealing assembly includes an upper fire sealing plate and a lower fire sealing plate, the lower fire sealing plate is connected to the anti-burning plate and the cover plate, the upper fire sealing plate is connected to the lower fire sealing plate, and the upper fire sealing plate is provided with a plurality of adjustment holes. By adjusting the upper fire sealing plate, the fire sealing control can be realized easily.

[0028] Furthermore, the furnace body is provided with an anti-scalding shell on the outside, a hot air channel is provided between the anti-scalding shell and the furnace body, and the anti-scalding shell is provided with an air inlet and an air outlet. The anti-scalding shell and the furnace body are directly provided with a hot air channel, a blower is connected to the hot air channel, and the hot air channel is provided with an air outlet. By providing the blower and the air outlet, the hot air in the hot air channel is blown out by the blower, so that the hot air can be quickly supplied to the room.

[0048] A fourth air distribution port 82 is provided between the heating chamber 12 and the combustion chamber 11;

[0049] The heat dissipation chamber 13 is connected to an exhaust pipe, an adjustable fire sealing component 5 is provided between the heat dissipation chamber 13 and the combustion chamber 11 , and a water heating switching plate 4 is provided between the heat dissipation chamber 13 and the heating chamber 12 .

[0050] The four air distributions have their own characteristics. In addition to supporting combustion, they also have the following functions:

[0051] 1. The charging port is also the secondary air distribution port 2. The secondary air at the charging port solves the problem that the silo door cannot be opened due to long-term fire blocking and tar in the storage silo adhering to the silo door.

[0052] 2. The three-way air flow at the cavity-type back-burning plate 6 solves the problem of short life of the back-burning plate 6 in the high-temperature zone. At present, the back-burning plates 6 of the stoves on the market are all single-layered, and the back-burning plates 6 are carbonized and delaminated during combustion.

[0053] Embodiment 2:

[0054] On the basis of Example 1, the middle portion of the anti-burning plate 6 protrudes toward the combustion chamber 11 .

[0055] The anti-burning plate 6 is in a “>” shape.

[0056] The tertiary air distribution port 62 is provided on the anti-firing plate 6 , and the tertiary air distribution port 62 is connected to the outside of the furnace body through the tertiary air inlet channel 7 .

[0057] The tertiary air distribution port 62 is mainly used to provide fresh air to the burning fuel, and the quaternary air distribution port 82 is mainly used to provide fresh air to the burning flame.

[0058] The primary air distribution enters the storage chamber 9 from the bottom of the storage chamber 9 through the grate 10 at the bottom of the furnace body, the secondary air distribution enters the storage chamber 9 through the feeding port, the tertiary air distribution enters the combustion chamber 11 through the tertiary air inlet channel 7, and the quaternary air distribution enters the combustion chamber 11 through the quaternary air inlet channel 81.

[0059] 1. The “>” type cavity anti-burning plate 6, because its middle part protrudes toward the combustion chamber 11, increases the volume of the storage chamber 9, and the storage chamber 9 is used for burning materials, thus increasing the capacity of the silo.

[0060] 2. The dry distillation area is increased (the dry distillation area refers to the storage chamber 9), and fuels with high humidity can be burned, and fuels with humidity within 30% can be burned.

[0061] 3. The air velocity at the closing part of the ">" structure (the bottom of the anti-burning plate 6) is high, which can make the combustible gas and the tertiary and quaternary air intakes fully mixed. The flame temperature is high and the energy-saving effect is obvious. The heating and cooking effects are good, and the water boiling and cooking can be comparable to liquefied gas.

[0062] 4. When the fuel is burning, the burning speed is fast at the throat (bottom) of the anti-burning plate 6. The fuel at the slope of the ">" structure slides down to the throat under the action of gravity to supplement the cavity produced by the combustion. (Other manufacturers use a straight anti-burning plate 6 which cannot supplement the combustion cavity at the throat well).

[0063] Embodiment 3:

[0064] On the basis of Example 2, the lower part of the storage chamber 9 is communicated with the lower part of the combustion chamber 11.

[0065] The upper portion of the storage chamber 9 is connected to the combustion chamber 11 through an overflow hole 61 .

[0066] The storage bin is equipped with a combustible gas overflow hole 61. A combustible gas overflow hole 61 is added to the upper part of the storage bin to solve the problem of the bin explosion (the dry distillation gasification furnace on the market does not have a combustible gas overflow hole 61, and the probability of the bin explosion is high)

[0067] A thickened guide platform 8 is provided inside the furnace body. The thickened guide platform 8 is provided with four air inlet channels 81 . The four air distribution ports 82 are connected to the outside of the furnace body through the four air inlet channels 81 .

[0068] The water heating switching plate 4 is arranged close to the cover plate 32, and one end of the water heating switching plate 4 is rotatably connected to the furnace body.

[0069] Embodiment 4:

[0070] On the basis of Example 3, Figure 5-7 As shown, the water heating assembly includes a cover plate 32 at the top, and two ends of the cover plate 32 are respectively connected to a water heating shell 3, and the water heating shell 3 is connected to a plurality of water heating pipes 31.

[0071] The water heating component is detachably connected to the furnace body, and the water heating component can be disassembled when actually in use.

[0072] Independently removable water heating element. Since cow and sheep manure contains high humidity and highly corrosive acidic substances, and the water heating part is more susceptible to corrosion due to its low temperature, the removable water heating element can also be replaced by the user.

[0073] Available in all seasons. The combustion system and water heating system can be switched freely, with powerful cooking function and good fuel adaptability. It can burn cow dung, sheep dung, wood, biomass pellets, combustible domestic garbage, etc. It can be used all year round.

[0074] The water heating assembly extends into the furnace body, and is connected to the furnace body through the water heating shells 3 on both sides, and the water heating pipe 31 is directly connected to the external heating pipeline to achieve water heating. There is a hollow structure between the two water heating shells 3, and only the water heating pipe 31 passes through, which is convenient for the circulation of heat.

[0075] When the water heating assembly is used, the water heating switch plate 4 is rotated to connect the heating chamber 12 with the heat dissipation chamber 13 , so that hot air will enter the heat dissipation chamber 13 through the heater and then be discharged, thereby heating the water heating shell 3 .

[0076] When the water heating component is not in use, the water heating switching plate 4 is rotated to overlap the water heating switching plate 4 with the furnace body, blocking the heating chamber 12 and the heat dissipation chamber 13, so that the hot air will directly enter the heat dissipation chamber 13 through the combustion chamber 11 and then be discharged.

[0077] Figure 1 The two working positions of the water heating switch board 4 are drawn in the figure. The solid line is drawn for the state where the water heating component is not used, and the dotted line is drawn for the state where the water heating component is used.

[0078] Embodiment 5:

[0079] Based on Example 4, the adjustable fire sealing assembly 5 includes an upper fire sealing plate 51 and a lower fire sealing plate 52, the lower fire sealing plate is connected to the anti-burning plate 6 and the cover plate 32, the upper fire sealing plate is connected to the lower fire sealing plate 52, and the upper fire sealing plate is provided with a plurality of adjustment holes 53.

[0080] By adjusting the upper fire sealing plate 51, fire sealing control can be realized conveniently.

[0081] Two fire-blocking plates and two fire channels. The fire-blocking time can be adjusted when switching the fire-blocking plates, the fire power can be adjusted, and the fire-blocking time can be adjusted. This solves the problem of short fire-blocking time when burning cow dung and sheep dung, and the fire-blocking time for burning cow dung and sheep dung is more than 8 hours. The two solve the problem of smoke coming out of the charging door when the furnace lid is opened for cooking (the dry distillation gasification stoves on the market have the phenomenon of smoke coming out of the charging bin door when the furnace lid is opened for cooking)

[0082] The grate 10 is a push-pull grate 10. The large-stroke push-pull grate 10 is pulled forward when burning cow dung to form coke. At this time, a large gap is left behind the grate 10, and the coke slag falls into the ash hopper. Then the grate 10 is pushed back to its original position. This solves the problem that the coking of cow dung affects the combustion. (When the fuel on the market is coked and taken out from the charging port with tongs, a large amount of dust flies out of the furnace and falls into the room)

[0083] Embodiment 6:

[0084] On the basis of Example 5, a scalding-proof shell 14 is provided outside the furnace body, a hot air channel 17 is provided between the scalding-proof shell 14 and the furnace body, and the scalding-proof shell 14 is provided with an air inlet (the air inlet is connected to a blower 15) and an air outlet 16.

[0085] Hot air heating. The product has an anti-scalding shell 14 installed on the outside of the furnace to prevent people and clothes from being scalded. The anti-scalding shell 14 increases the heat dissipation area. The shell is provided with air inlet and outlet 16. After installing pipes in the gap between the shell and the furnace body, it can be used for heating other rooms, solving the problem of multiple furnaces in one household and gas poisoning.

[0086] A hot air passage 17 is directly provided between the anti-scalding housing 14 and the furnace body. A blower 15 is connected to the hot air passage 17 . An air outlet 16 is provided in the hot air passage 17 .

[0087] By providing the blower 15 and the air outlet 16 , the blower 15 can blow out the hot air in the hot air passage 17 , so that the hot air can be quickly supplied into the room.

[0088] Specific working principle: When in use, fuel is added through the secondary air distribution port 2, and the bottom of the storage chamber 9 and the bottom of the combustion chamber 11 are the main combustion areas. While the bottom of the storage chamber 9 is burning, the upper fuel can be dry-distilled. When the fuel at the bottom is burned, the burned slag falls through the grate 10, and the fuel above falls down and continues to burn.

[0089] When cooking is needed, the water heating switching plate 4 is rotated so that the water heating switching plate 4 contacts the inner wall of the furnace body, and the upper fire sealing plate 51 is opened at the same time. At this time, the heat flows along the combustion chamber 11 and enters the heat dissipation chamber 13 for daily cooking.

[0090] When water heating is needed, the water heating switch plate 4 is turned so that the water heating switch plate 4 is in contact with the inner wall of the furnace body, and the upper fire sealing plate 51 is closed. At this time, heat enters the water heating component from the combustion chamber 11, heats the water heating pipe 31, and then passes through the heating chamber 12 to the right side of the furnace body ( Figure 1 on the right side of the drain.

[0091] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
