A bending blade is arranged inside the first inner cavity, and the bending blade is fixedly connected to the inner wall of the feeding end - in a circle.

[0018] Preferably, a method for using an atmosphere feeding structure for a pressure - bearing tubular screw ribbon furnace includes the following steps:

[0019] S1: When using this pressure - bearing tubular screw ribbon furnace, adjust the inclination of the whole machine through the chassis adjustment mechanism, and then turn on the gear pneumatic drive mechanism and the rotating shaft power drive mechanism. Drive the gear ring to rotate through the gear pneumatic drive mechanism, and then provide rotational kinetic energy to the rotating ring by the rotating shaft power drive mechanism;

[0020] S2: The material enters the conveying cavity through the provided feeding nozzle. The rotating tubular screw ribbon furnace body drives the feeding end - and the conveying pipeline to rotate. Thus, after the material enters the conveying cavity, it is conveyed forward into the first inner cavity, and then through the opening where the first inner cavity contacts the tubular screw ribbon furnace body, the material enters the stirring pipe.

[0021] S3: When setting for stirring, the started equipment first rotates in the positive direction to continuously convey the material inside the stirring tube. With the arrangement of the first thread blades, the material entering the stirring tube is conveyed forward, and the material can be conveyed from the first conveying cavity to the interactive winding cavity. Meanwhile, the small first thread blades are only arranged at the position of the interactive winding cavity, and the direction of the second thread blades is opposite to that of the first thread blades and the small first thread blades. Thus, when the equipment rotates in the positive direction, the second thread blades are arranged in the position area of the interactive winding cavity, and the material is only conveyed to the interactive winding cavity and stops conveying forward. When the material stops entering the feed nozzle, the conveyed material can finally completely concentrate in the interactive winding cavity. With the heating mechanism started, the heat can be effectively transferred to the interactive winding cavity area of the stirring tube;

[0022] S4: During the material stirring process, the atmosphere gas is added through the arranged atmosphere gas input pipe. After being added by the atmosphere gas input pipe, it is conveyed to the collecting block, and then from the collecting block, it is conveyed to the atmosphere gas conveying pipe through the dispersion pipe. Finally, the gas is conveyed into the stirring tube through the atmosphere gas conveying pipe to supply the material during the reaction;

[0023] S5: When the set time for drying and stirring the material is reached, the forward rotation of the gear pneumatic drive mechanism and the rotating shaft power drive mechanism is stopped, and then it rotates in the reverse direction. When rotating in the reverse direction, the whole machine rotates in the reverse direction synchronously. Thus, due to the arrangement of the second thread blades, the material can be conveyed forward in the stirring tube and finally enters the discharging rotating pipe, and then through the discharging rotating pipe into the discharging pipe to discharge the material from the inside of the device.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. Through the first conveying cavity, the interactive winding cavity, and the second conveying cavity provided inside the stirring tube, as well as the first thread leaf, the small first thread leaf, and the second thread leaf provided inside the first conveying cavity, the interactive winding cavity, and the second conveying cavity, and the first thread leaf and the second thread leaf are in opposite directions. The device first rotates in the forward direction to continuously convey the material inside the stirring tube. As the first thread leaf is provided, the material entering the stirring tube is conveyed forward and can be conveyed from the first conveying cavity to the interactive winding cavity. At the same time, the small first thread leaf is only provided at the position of the interactive winding cavity, and the second thread leaf is in the opposite direction to the first thread leaf and the small first thread leaf. Therefore, when the device rotates in the forward direction, the second thread leaf is provided in the position area of the interactive winding cavity, and the material is only conveyed to the interactive winding cavity and stops moving forward. When the material stops entering the feed nozzle, the conveyed material can finally concentrate all the material in the interactive winding cavity. With the heating mechanism turned on, the heat can be effectively transferred to the interactive winding cavity area of the stirring tube. After the set drying and stirring time is reached, the forward rotation of the gear pneumatic drive mechanism and the rotating shaft power drive mechanism is stopped, and then it rotates in the reverse direction. When rotating in the reverse direction, the whole machine rotates in the reverse direction synchronously. Therefore, due to the setting of the second thread leaf, the material can be conveyed forward in the stirring tube and output from the inside of the stirring tube, effectively avoiding the problem that in the existing tube spiral belt furnace during the stirring reaction of the material, the material inside cannot be evenly distributed and concentrated in one place for heating, resulting in uneven stirring, tumbling, and heating of the material.

[0045] Embodiment 3

[0046] Please refer to Figures 1-5 , a method for using an atmosphere feeding structure for a pressure-bearing tube-and-ribbon furnace includes the following steps:

[0047] S1: When using the pressure-bearing tube spiral ribbon furnace, adjust the inclination of the whole machine through the chassis adjustment mechanism 103, then turn on the gear pneumatic drive mechanism 101 and the rotating shaft power drive mechanism 102. Drive the gear ring 203 to rotate through the gear pneumatic drive mechanism 101, and then provide the rotational kinetic energy for the rotating ring 201 by the rotating shaft power drive mechanism 102;

[0048] S2: The material enters the conveying cavity 403 through the set feed nozzle 401. The rotating tube spiral ribbon furnace main body 200 drives the feed end 200-1 and the conveying pipeline 402 to rotate. Therefore, after the material enters the conveying cavity 403, it is conveyed forward into the first inner cavity 206, and then through the opening where the first inner cavity 206 contacts the tube spiral ribbon furnace main body 200, the material enters the stirring tube 209.

[0049] S3: When setting for stirring, the started equipment first rotates in the positive direction to continuously convey the material inside the stirring tube 209. With the setting of the first thread blade 20902, the material entering the stirring tube 209 is conveyed forward, and the material can be conveyed from the first conveying cavity 20901 to the interactive winding cavity 20903. At the same time, the set small first thread blade 20904 is only set at the position of the interactive winding cavity 20903, and the set second thread blade 20906 is in the opposite direction to the first thread blade 20902 and the small first thread blade 20904. Therefore, when the equipment rotates in the positive direction, the second thread blade 20906 is set in the position area of the interactive winding cavity 20903, and the material is only conveyed to the interactive winding cavity 20903 and then stops conveying forward. When the material stops entering the feed nozzle 401, the conveyed material can finally concentrate all the material in the interactive winding cavity 20903. With the opening of the heating mechanism 211, the heat is effectively transferred to the interactive winding cavity 20903 area of the stirring tube 209;

[0050] S4: During the material stirring process, add the atmosphere gas through the set atmosphere gas input pipe 700. After being added by the atmosphere gas input pipe 700, it is conveyed to the collecting block 701, and then from the collecting block 701 through the dispersion pipeline 702 to the atmosphere gas conveying pipe 703. Finally, the gas is conveyed into the stirring tube 209 through the atmosphere gas conveying pipe 703 to supply the needs during the material reaction;

[0051] S5: When the set time for material drying and stirring is reached, stop the forward rotation of the gear pneumatic drive mechanism 101 and the rotating shaft power drive mechanism 102, so as to rotate in the reverse direction. When rotating in the reverse direction, the whole machine rotates in the reverse direction synchronously. Thus, due to the arrangement of the second thread blades 20906 on the stirring pipe 209, the material can be continuously conveyed forward in the stirring pipe 209 and finally enter the discharging rotating pipe 500, and then enter the discharging pipe 600 through the discharging rotating pipe 500 to discharge the material from the inside of the device.

9. A gas-feeding structure according to claim 8, which is used for a pressure-bearing tubular spiral ribbon furnace, is characterized in that: One end of the shell-and-tube helical ribbon furnace main body (200) is provided with a feed end (200-1). The feed end (200-1) is provided with a first inner cavity (206). Inside the first inner cavity (206), a curved blade (207) is provided, and the curved blade (207) is fixedly connected to the inner wall of the feed end (200-1) around it.

10. A method of using an atmosphere feeding structure as claimed in claims 1-9 for a pressure-bearing shell-and-tube spiral ribbon furnace, characterized in that, Including the following steps: S1: When using the pressure-bearing tube spiral ribbon furnace, adjust the inclination of the whole machine through the chassis adjustment mechanism (103), then turn on the gear pneumatic drive mechanism (101) and the rotating shaft power drive mechanism (102). Drive the gear ring (203) to rotate through the gear pneumatic drive mechanism (101), and then the rotating shaft power drive mechanism (102) provides the rotational kinetic energy for the rotating ring (201). S2: The material enters the conveying cavity (403) through the set feed nozzle (401). The rotating tube spiral ribbon furnace body (200) drives the feed end (200-1) and the conveying pipeline (402) to rotate. Thus, after the material enters the conveying cavity (403), it is conveyed forward into the first inner cavity (206), and then through the opening where the first inner cavity (206) contacts the tube spiral ribbon furnace body (200), the material enters the stirring tube (209). S3: When setting for stirring, the started equipment first rotates in the forward direction, so that the material is continuously conveyed inside the stirring tube (209). With the setting of the first thread blade (20902) after the material enters the stirring tube (209), the material is conveyed forward, and the material can be conveyed from the first conveying cavity (20901) to the interwinding cavity (20903). At the same time, the set small first thread blade (20904) is only set at the position of the interwinding cavity (20903). The set second thread blade (20906) is in the opposite direction to the first thread blade (20902) and the small first thread blade (20904). Thus, when the equipment rotates in the forward direction, the second thread blade (20906) is set in the position area of the interwinding cavity (20903), and the position where the material is conveyed only conveys the material to the interwinding cavity (20903) and then stops conveying forward. When the material stops entering the feed nozzle (401), the conveyed material can finally concentrate the material completely in the interwinding cavity (20903). With the opening of the heating mechanism (211), the heat is effectively transferred to the interwinding cavity (20903) area of the stirring tube (209). S4: During the material stirring process, add the atmosphere gas through the set atmosphere gas input pipe (700). After being added by the atmosphere gas input pipe (700), it is conveyed to the collecting block (701), and then the collecting block (701) conveys it to the atmosphere gas conveying pipe (703) through the dispersion pipeline (702). Finally, the gas is conveyed into the stirring tube (209) through the atmosphere gas conveying pipe (703) for supply when the material reacts. S5: When the set time for material drying and stirring is reached, stop the forward rotation of the gear pneumatic drive mechanism (101) and the rotating shaft power drive mechanism (102), and then rotate in the reverse direction. When rotating in the reverse direction, the whole machine rotates in the reverse direction synchronously. As a result, due to the arrangement of the second threaded blade (20906) in the stirring pipe (209), the material can be continuously conveyed forward in the stirring pipe (209), and finally enters the discharging rotating pipe (500), and then enters the discharging pipe (600) through the discharging rotating pipe (500) to discharge the material from the inside of the device.
