Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 、 Figure 2 and Figure 4, an embodiment provided by the present utility model: a five-stage pyrolysis gasification furnace, which includes a combustion chamber 1. A hollow shell 3 is fixedly connected to the top of the combustion chamber 1. A first hollow cone 4 is arranged on the upper side of the hollow shell 3.

A fixed column 19 is arranged inside the hollow column 205. The bottom of the fixed column 19 is fixedly connected to the inner bottom end of the second hollow cone 13. The top end of the fixed column 19 is fixedly connected to a combustion furnace 20;

[0033] Specifically, when using this device, first, the staff pours solid waste into the combustion chamber 1 from the feed inlet 14. Then, the combustion furnace 20 is started to heat the solid waste in the combustion chamber 1. When the combustion furnace 20 is started, the first motor 6 is also started accordingly. After the first motor 6 is started, it drives the driving bevel gear 7 to rotate. Since the driven bevel gear 9 is meshed with the driving bevel gear 7, when the driving bevel gear 7 rotates, the driven bevel gear 9 will also be driven to rotate, thereby driving the connected hollow rod 8 to rotate. When the hollow rod 8 rotates, it will drive the connected plurality of hollow stirring rods 10 to rotate together. At the same time, the air inlet pipe 12 connected to the top end of the hollow rod 8 is connected to a blower. At this time, the blower is started, and after the blower is started, it sends air into the hollow rod 8 through the air inlet pipe 12. After the air enters the hollow rod 8, it will enter the hollow stirring rods 10 along the hollow rod 8, and then be dispersed into the combustion chamber 1 through the holes 11 on the hollow stirring rods 10. In this way, the oxygen content in the combustion chamber 1 can be increased. At this time, through the stirring action of the hollow stirring rods 10 and the continuously supplied oxygen, the solid waste in the combustion chamber 1 can fully react, improving the practicability of this device and meeting the needs of users.

[0034] Refer to Figure 1 and Figure 5, the collecting mechanism 2 includes a fixing plate 201, the fixing plate 201 is fixedly connected to the lower middle part on the right side of the second hollow cone 13, a second motor 202 is fixedly connected to the top of the fixing plate 201, the output end of the second motor 202 penetrates through the second hollow cone 13 and is fixedly connected to a transmission rod 203, a worm 204 is fixedly connected to the right end of the transmission rod 203, the middle part of the inner bottom end of the second hollow cone 13 is rotatably connected to a hollow column 205, a worm gear 206 is fixedly connected to the middle and lower part on the outer side of the hollow column 205, the worm gear 206 is meshed and connected with the worm 204, the top end of the hollow column 205 sequentially penetrates through the second hollow cone 13 and the combustion chamber 1, straight scraping plates 207 are fixedly connected to both the left and right side top ends of the hollow column 205, a first filter screen 208 is fixedly connected to the middle and lower part on the inner side of the combustion chamber 1, a plurality of curved scraping plates 209 are fixedly connected to the outer side of the hollow column 205, and a collecting port 210 is communicated with the bottom end on the right side of the combustion chamber 1;

[0035] Specifically, after the reaction in the combustion chamber 1 proceeds for a period of time, the second motor 202 is started and drives the transmission rod 203 to start rotating. Once the transmission rod 203 rotates, it will drive the worm 204 connected thereto to rotate. Due to the meshing between the worm gear 206 and the worm 204, when the worm 204 rotates, the worm gear 206 will rotate accordingly, thereby driving the hollow column 205 to rotate. When the hollow column 205 rotates, it will drive the straight scraping plates 207 and the curved scraping plates 209 connected thereto to rotate together. When the straight scraping plate 207 rotates, it will scrape the ash accumulated on the first filter screen 208. Under the scraping of the straight scraping plate 207, the ash accumulated on the first filter screen 208 can smoothly fall to the bottom of the combustion chamber 1. After the ash falls to the bottom of the combustion chamber 1, the curved scraping plate 209 will scrape the ash that has fallen to the bottom of the combustion chamber 1 and push the ash to move outward. Eventually, the ash will fall out of the combustion chamber 1 through the collecting port 210, thus completing the cleaning and collection work of the ash and reducing the workload of the staff.

[0036] Refer to Figure 1 , Figure 2 and Figure 3 , a feed port 14 is communicated with the top end on the left side of the combustion chamber 1, a gas collecting port 15 is communicated with the middle and upper part on the right side of the hollow shell 3, a second filter screen 16 is fixedly connected to the left side inside the gas collecting port 15, a gas collecting cover 17 is threadedly connected to the right end of the gas collecting port 15, and a plurality of screws 18 are threadedly connected to the periphery of the top of the first hollow cone 4. The bottom ends of the plurality of screws 18 all penetrate through the first hollow cone 4 and are threadedly connected to the same hollow shell 3;

[0037] Specifically, solid waste can be added into the combustion chamber 1 through the feed inlet 14, combustible gas generated by the device can be collected through the gas collection port 15, the combustible gas can be filtered through the second filter screen 16, the gas collection port 15 can be closed by the gas collection cover 17 when the combustible gas does not need to be collected, and the first hollow cone 4 can be disassembled by unscrewing a plurality of screws 18 for maintaining the device.

[0038] Refer to Figure 1 and Figure 3 As shown in the figure, fixed pieces 22 are fixedly connected to the bottoms of a plurality of support legs 21, fixing holes 23 are formed in the tops of the plurality of fixed pieces 22, a controller 24 is fixedly connected to the middle and lower part of the front side of the combustion chamber 1, and the controller 24 is electrically connected to the first motor 6 and the second motor 202 respectively;

[0039] Specifically, the plurality of support legs 21 can be fixed through the fixed pieces 22, and screws can be installed inside the fixing holes 23 for fixation. The operations of the first motor 6 and the second motor 202 can be controlled respectively through the controller 24. The models of both the first motor 6 and the second motor 202 are MS8012.

[0040] Working principle: When using this device, first pour the solid waste into the combustion chamber 1 from the feed inlet 14, and then start the combustion furnace 20 to heat the solid waste. At this time, the first motor 6 will start. The start of the first motor 6 will drive the driving bevel gear 7 to rotate. Since the driven bevel gear 9 meshes with the driving bevel gear 7, the driven bevel gear 9 will drive the hollow rod 8 to rotate accordingly. When the hollow rod 8 rotates, it will drive a plurality of hollow stirring rods 10 to rotate together. At the same time, the air inlet pipe 12 connected to the top end of the hollow rod 8 is connected to a blower. At this time, the blower will start and send air into the hollow rod 8 through the air inlet pipe 12. The air then enters the hollow stirring rods 10 through the hollow rod 8 and is dispersed into the combustion chamber 1 through the holes 11, increasing the oxygen content in the combustion chamber 1. At this time, the solid waste in the combustion chamber 1 can fully react through stirring and the supplied oxygen;

[0041] And after the reaction in the combustion chamber 1 proceeds for a period of time, the second motor 202 starts and drives the transmission rod 203 to rotate. The rotation of the transmission rod 203 will drive the worm 204 to rotate. Since the worm gear 206 meshes with the worm 204, the worm gear 206 will drive the hollow column 205 to rotate accordingly. When the hollow column 205 rotates, it will drive the straight scraper 207 and the curved scraper 209 to rotate. When the straight scraper 207 rotates, it will scrape the ash accumulated on the first filter screen 208, making it fall smoothly to the bottom of the combustion chamber 1. When the ash falls to the bottom of the combustion chamber 1, the curved scraper 209 will scrape it and push it to move outward, and finally it will fall out through the collection port 210, thus easily completing the collection work of the reaction ash.
