Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.
[0032] Referring to Figure 1 , Figure 3 and Figure 5 , an embodiment provided by the present utility model: a pressurized pyrolysis gasification furnace, including a furnace body 1 and a special-shaped scraper 11. A furnace cover 3 is provided at the top of the furnace body 1. A gas outlet pipe 4 is connected to the right side of the top of the furnace cover 3. A double-headed motor 5 is fixedly connected to the left side of the gas outlet pipe 4. A driving bevel gear 6 is fixedly connected to the left output end of the double-headed motor 5. A rotating rod 7 is rotatably connected to the middle of the top of the furnace cover 3. A fixing rod 8 is fixedly connected to the top of the rotating rod 7. A driven bevel gear 9 is fixedly connected to the outer side of the fixing rod 8. The driven bevel gear 9 is meshed with the driving bevel gear 6. The middle and lower part of the rotating rod 7 penetrates through the furnace cover 3. A plurality of stirring rods 10 are fixedly connected to the outer periphery of the rotating rod 7 at equal intervals. One ends of the plurality of stirring rods 10 are respectively fixedly connected to one side of the corresponding special-shaped scraper 11. A vibration mechanism 2 is arranged inside the gas outlet pipe 4. The vibration mechanism 2 is used to facilitate the collection of the processed combustible gas. The sizes of the plurality of special-shaped scrapers 11 are all matched with the sizes of the inner periphery of the furnace body 1;
[0033] Specifically, start the double-headed motor 5 and the heating rod 14. The heat generated by the heating rod 14 can be transferred to the materials inside the furnace body 1 so that the materials can be pyrolyzed under a suitable temperature environment. At the same time, one output end of the double-headed motor 5 can drive the driving bevel gear 6 to rotate, and the meshed driven bevel gear 9 will also rotate accordingly. The rotation of the driven bevel gear 9 further drives the rotation of the rotating rod 7, and the stirring rods 10 installed thereon will also rotate synchronously. The design of the stirring rods 10 can fully disperse the materials inside the furnace body 1, thereby accelerating the rate of the pyrolysis reaction. While the stirring rods 10 are rotating, the special-shaped scrapers 11 on their outer sides will rotate together to effectively scrape the inner wall of the furnace body 1, which can avoid the situation that impurities remain on the inner wall of the furnace body 1 and cause inconvenience for the staff to clean, thereby reducing the workload of the staff and meeting the needs of users.
[0034] Referring to Figure 2 , Figure 3 and Figure 4, the vibration mechanism 2 includes a disc 201 and a connecting rod 208. The disc 201 is arranged inside the air outlet pipe 4. The right output end of the double-headed motor 5 penetrates through the air outlet pipe 4 and is fixedly connected to one side of the disc 201. A fixed column 202 is fixedly connected to the right side of the disc 201. The right end of the fixed column 202 is rotatably connected to a first rotating shaft 203. The middle and lower part inside the air outlet pipe 4 is fixedly connected with a filter screen 210. The top of the filter screen 210 is fixedly connected with a fixing plate 204. A chute 205 is opened in the upper middle part of one side of the fixing plate 204. A slider 206 is slidably connected inside the chute 205. The left side of the slider 206 is rotatably connected to a second rotating shaft 207. The second rotating shaft 207 is connected to the first rotating shaft 203 through the connecting rod 208. The bottom right side of the slider 206 is fixedly connected with a knocking rod 209;
[0035] Specifically, the double-headed motor 5 can drive the disc 201 to rotate. During the rotation of the disc 201, the first rotating shaft 203 on it will rotate synchronously. With the rotation of the first rotating shaft 203, through the ingenious connection of the connecting rod 208, the power is further transmitted to the second rotating shaft 207, so as to drive the second rotating shaft 207 to rotate. At this time, the knocking rod 209 will move up and down inside the chute 205 to knock on the filter screen 210. Through continuous knocking, it can ensure that impurities on the filter screen 210 will not accumulate in large amounts, and always keep the pores of the filter screen 210 unblocked, so as to ensure that gas can smoothly pass through the filter screen 210 and enter the air outlet pipe 4 and be smoothly discharged into the next processing link, thereby improving the practicability of the device.
[0036] Refer to Figure 1 and Figure 2 , a cavity 13 is opened inside the furnace body 1. A plurality of heating rods 14 are fixedly connected at equal intervals around the inner bottom of the cavity 13. Bolts 12 are threadedly connected to both the left and right sides of the furnace cover 3. One end of the bolt 12 sequentially penetrates through the furnace cover 3 and the furnace body 1;
[0037] Specifically, the heating rods 14 can pyrolyze the materials inside the furnace body 1, and the provided bolts 12 can release the limit fixation of the furnace cover 3. At this time, the furnace cover 3 can be removed to carry out maintenance work on the structure at its bottom.
[0038] Refer to Figure 1 and Figure 2 , a feeding port 15 is communicated with the front side of the top of the furnace cover 3. A discharging port 16 is communicated with the bottom of the furnace body 1. Sealing covers 17 are threadedly connected to the far ends of the feeding port 15 and the discharging port 16. An observation window 19 is arranged in the middle of the front side of the furnace body 1;
[0039] Specifically, the charging port 15 facilitates the feeding of materials into the furnace body 1, the provided discharge port 16 facilitates the collection of the solids generated after the pyrolysis treatment of the materials, and the provided observation window 19 facilitates the staff to check the internal situation of the furnace body 1 at any time.
[0040] Refer to Figure 1 , on the right side of the furnace body 1, a control panel 18 is fixedly connected, and the control panel 18 is electrically connected to the double-headed motor 5;
[0041] Specifically, the operation of the double-headed motor 5 can be controlled through the control panel 18, and the model of the double-headed motor 5 is 63ZYT.
[0042] Working principle: When using this furnace body 1, first unscrew the sealing cover 17 on the charging port 15, then pour the material to be processed into the furnace body 1 through the charging port 15, and finally screw on the sealing cover 17. At this time, start the double-headed motor 5 and the heating rod 14. The heat generated by the heating rod 14 can be transferred to the materials inside the furnace body 1, so that the pyrolysis treatment work can be carried out. One output end of the double-headed motor 5 can drive the driving bevel gear 6 to rotate, and the driven bevel gear 9 engaged with it will rotate accordingly, which can drive the rotating rod 7 to rotate. At this time, the stirring rod 10 on the rotating rod 7 will rotate accordingly to disperse the materials inside the furnace body 1, thereby improving the pyrolysis efficiency of the materials. The special-shaped scraping plate 11 on the stirring rod 10 will rotate accordingly to scrape the inner wall of the furnace body 1, which can avoid the situation that the inner wall of the furnace body 1 remains with impurities and causes inconvenience for the staff to clean;
[0043] And after the pyrolysis work is completed, the solids generated by the materials can be collected through the discharge port 16. The generated gas will first filter the impurities inside through the filter screen 210, and then be discharged into the next treatment link through the air outlet pipe 4. When the double-headed motor 5 is started, its other output end can drive the disc 201 to rotate, and the first rotating shaft 203 on the disc 201 will rotate accordingly. The second rotating shaft 207 will also rotate through the connecting rod 208, which can drive the knocking rod 209 to move up and down inside the sliding groove 205 to continuously knock on the filter screen 210, which can avoid the impurities in the processed gas from blocking the filter screen 210 and affecting the subsequent gas treatment work.
