[0036] like Figure 3 、 Figure 10 As shown, specifically, a plurality of evenly distributed suspension racks 31 are fixedly installed on the bottom of the deodorizing barrel 1, and the bottom ends of the plurality of suspension racks 31 are fixedly installed with the same air outlet track 32. One end of the air outlet pipe 11 is connected to the interior of the air outlet track 32, and an air outlet slip ring 33 is slidably installed on the air outlet track 32, and a docking pipe 34 is fixedly installed on one side of the air outlet slip ring 33.

[0037] More specifically, by providing a docking pipe 34, when exhausting air, the hot air is transported to the inside of the air outlet track 32 and the air outlet slip ring 33 through the air outlet pipe 11, and then discharged into the exhaust pipe through the docking pipe 34. The air outlet slip ring 33 can rotate inside the air outlet track 32, and then adjust the position and direction of the docking pipe 34, so that the hot air outlet can be freely adjusted to meet different production needs.

[0038] like Figure 10 As shown, specifically, an interlayer flange 35 is movably sleeved on one end of the butt joint 34 , and two arc-shaped fastening claws 30 adapted to the air outlet track 32 are fixedly mounted on the side wall of the interlayer flange 35 .

[0039] More specifically, by setting the first diffuser 6 of the rectifier box 3, after adjusting the position of the docking pipe 34, the interlayer flange 35 is sleeved on the interlayer flange 35, so that the interlayer flange 35 is docked with the flange of the docking pipe 34 itself, and then the external pipe is docked and locked with the docking pipe 34 through the flange. The interlayer flange 35 is clamped in the middle by the flanges of the two pipes, so that the two arc-shaped fastening claws 30 press the air outlet track 32, thereby fixing the docking pipe 34 and realizing the positioning of the docking pipe 34.

[0040] The deodorizing barrel 1 is provided with a control mechanism for automatically opening and closing the air outlet pipe 11. Figure 5 As shown, specifically, the control mechanism includes a driven gear ring 15 rotatably mounted on the top inner wall of the deodorizing barrel 1, as shown in FIG. Figure 2 、 Figure 3 As shown, a motor box 12 is fixedly installed on the top of the deodorizing barrel 1, and a control motor 13 is fixedly installed inside the motor box 12. Figure 5 As shown, the output shaft of the control motor 13 extends to the interior of the deodorizing barrel 1 and is fixedly sleeved with a control gear 14 that meshes with the driven gear ring 15. The feed pipe 9 is located at one end inside the deodorizing barrel 1 and is fixedly sleeved with a hanging plate 16. A control ring 17 is rotatably installed between the inner wall of the deodorizing barrel 1 and the outer ring side wall of the hanging plate 16. The control ring 17 is fixedly installed at the bottom of the driven gear ring 15. A plurality of stirring rods 18 evenly distributed along the second diffusion bucket 8 are fixedly installed at the bottom of the control ring 17, as shown in FIG. Figure 6 、 Figure 7As shown, the bottom ends of the multiple stirring rods 18 are fixedly mounted with a same switch cone ring 19 , and the side wall of the switch cone ring 19 is provided with three switch air holes 1901 , which are adapted to the air outlet pipe 11 .

[0041] More specifically, by setting up a control mechanism, during the air supply and deodorization process, the control motor 13 inside the motor box 12 will drive the control gear 14 on the top of the suspension plate 16 to rotate, and then drive the control ring 17 to rotate through the meshing driven gear ring 15, and then drive the three stirring rods 18 at the bottom to deflect slightly, disturbing and stirring the material, accelerating the dispersion of harmful substances, and at the same time driving the switch cone ring 19 at the bottom to rotate, so that the three switch air holes 1901 are all misaligned with the air outlet pipe 11, so that the air outlet pipe 11 is closed by the switch cone ring 19, disconnecting the output channel of the hot air, and allowing the hot air to circulate inside the deodorization barrel 1 for deodorization.

[0042] The bottom of the deodorizing barrel 1 is provided with an external circulation unit for external circulation of the gas inside the deodorizing barrel 1. Figure 4 、 Figure 9 As shown, specifically, the external circulation unit includes a C-shaped tube 22 arranged at the bottom of the deodorizing barrel 1, and the inner ring of the C-shaped tube 22 is fixedly installed with three exhaust pipes 20 evenly distributed along the second diffusion bucket 8. One end of the exhaust pipe 20 extends to the interior of the deodorizing barrel 1 and is fixedly installed with an isolation net 21 adapted to the side wall of the switch cone ring 19. An external circulation pipe 23 is fixedly installed on one side of the C-shaped tube 22, as shown in FIG. Figure 2 As shown, a circulation pump 24 is fixedly installed at one end of the three-way valve 4, one end of the external circulation pipe 23 is connected to the air inlet end of the circulation pump 24, and the air outlet end of the circulation pump 24 is connected to the three-way valve 4.

[0043] In this embodiment, the air outlet pipe 11, the end of the exhaust pipe 20 located inside the deodorizing barrel 1, and the top of the isolation net 21 all have a concave arc surface structure, which is compatible with the outer ring side wall of the switch cone ring 19.

[0044] More specifically, by setting up an external circulation unit, the switch air hole 1901 will be misaligned with the air outlet pipe 11 and will be rotated to a position where it connects with the three exhaust pipes 20, so that the exhaust pipe 20 is connected to the interior of the deodorizing barrel 1. At this time, the three-way valve 4 disconnects the first air duct 5 from the rectifier box 3, and connects the circulation pump 24 to the three-way valve 4. Then the hot air conveying equipment 2 stops conveying hot air, and the circulation pump 24 pumps it. After deodorization, the hot air is conveyed to the C-shaped tube 22 through the three exhaust pipes 20, and then is extracted into the first air duct 5 through the external circulation pipe 23 and the circulation pump 24 for circulation, thereby realizing the external circulation of the hot air and increasing the number of cycles of the hot air, thereby enhancing the emission of harmful substances by the hot air and improving the deodorization effect.

[0045] The deodorizing barrel 1 is provided with an internal circulation unit for internal circulation of the gas inside the deodorizing barrel 1. Figure 4 、 Figure 8 As shown, specifically, a plurality of evenly distributed support frames 25 are fixedly installed inside the deodorizing barrel 1, and a vertically arranged skid-shaped internal circulation pipe 26 is fixedly installed on the support frame 25. The bottom end of the skid-shaped internal circulation pipe 26 is fixedly installed with an inclined switch air pipe 27, and the positions of the three switch air pipes 27 correspond to the positions of the three exhaust pipes 20 respectively.

[0046] In this embodiment, the bottom end of the switch air pipe 27 is an outward convex arc structure, which is compatible with the inner ring side wall of the switch cone ring 19, and the top end of the skid-shaped internal circulation pipe 26 is bent downward to prevent material from entering the interior of the skid-shaped internal circulation pipe 26.

[0047] More specifically, by setting up an internal circulation unit, when the exhaust pipe 20 is connected to the switch air hole 1901, the switch air pipe 27 at the bottom end of the sled-shaped internal circulation pipe 26 will be connected to the other end of the switch air hole 1901, so that the hot air can only enter the sled-shaped internal circulation pipe 26 through the bent opening at the top of the sled-shaped internal circulation pipe 26, and then enter the external circulation through the switch air hole 1901, so that the hot air can be internally circulated inside the deodorizing barrel 1 through the first diffusion bucket 6, the stirring rod 18, and the switch air pipe 27, further improving the diffusion range of the hot air and ensuring the deodorizing effect.

[0048] like Figure 6 、 Figure 8 As shown, specifically, a plurality of auxiliary circulation pipes 28 evenly distributed from top to bottom are fixedly mounted on the side wall of the skid-shaped inner circulation pipe 26, and the openings of the auxiliary circulation pipes 28 are all vertically downward.

[0049] More specifically, by setting up the auxiliary circulation pipe 28, the auxiliary circulation pipe 28 adds multiple air inlets evenly distributed from top to bottom to the skid-shaped inner circulation pipe 26, so that hot air can flow into the skid-shaped inner circulation pipe 26 from the top of the skid-shaped inner circulation pipe 26 and the bottom of the auxiliary circulation pipe 28 simultaneously, which plays a guiding role in the internal circulation of the hot air, so that the hot air circulates in each layer of the material, accelerating the dispersion of harmful substances.

[0050] like Figure 6 、 Figure 7 As shown, specifically, a plurality of evenly distributed switch plate frames 29 are fixedly sleeved on the stirring rod 18 , and the positions of the plurality of switch plate frames 29 respectively correspond to the bottom ends of the plurality of auxiliary circulation pipes 28 .

[0051] In this embodiment, if Figure 7 As shown, the connection between the switch plate frame 29 and the stirring rod 18 is an arc-shaped rod structure, and the end thereof away from the stirring rod 18 is a solid circular plate for sealing the bottom end of the auxiliary circulation pipe 28.

[0052] More specifically, by setting the switch plate rack 29, when the hot air circulation time is sufficient, the stirring rod 18 drives the switch conical ring 19 to rotate in the opposite direction by the same angle, so that the exhaust pipe 20 and the switch air pipe 27 are both blocked, and the switch plate rack 29 is synchronously moved to the bottom end of the secondary circulation pipe 28 to block the secondary circulation pipe 28. At this time, the hot air cannot circulate inside and outside through the skid-shaped internal circulation pipe 26, and the air outlet pipe 11 is re-connected with the interior of the deodorization barrel 1. The deodorized hot air is discharged through the air outlet pipe 11, completing the initial deodorization of the material. After that, the three-way valve 4 reconnects the rectifier box 3 with the first air duct 5, and the hot air conveying equipment 2 continues to convey hot air for a new round of deodorization.

[0053] In summary: when the dual-duct deodorization equipment is in use, the material is poured into the deodorization barrel 1 from the feed pipe 9 on the top of the deodorization barrel 1, so that the material accumulates in the deodorization barrel 1, and then the hot air conveying equipment 2 draws air for filtration and heating before conveying it to the rectification box 3 for rectification and preliminary dispersion, and then conveyed to the deodorization barrel 1 through the first air duct 5 and the second air duct 7 respectively, and double-layer diffusion is performed through the first diffusion hopper 6 above and the second diffusion hopper 8 below, so as to dry and deodorize the material inside the deodorization barrel 1, and discharge it from the air outlet pipe 11 together with the harmful substances emitted by the material, and finally the shut-off valve 10 at the bottom of the deodorization barrel 1 is opened, the material is discharged, and the automatic deodorization of the material is completed. The dual-duct structural setting can increase the diffusion range of the hot air and improve the deodorization effect on the material. A control mechanism is provided so that during the process of air delivery and deodorization, the control motor 13 inside the motor box 12 will drive the control gear 14 on the top of the suspension plate 16 to rotate, and then drive the control ring 17 to rotate through the meshing driven gear ring 15, and then drive the three stirring rods 18 at the bottom to deflect slightly, disturbing and stirring the material, accelerating the dispersion of harmful substances, and at the same time driving the switch cone ring 19 at the bottom to rotate, so that the three switch air holes 1901 are all misaligned with the air outlet pipe 11, so that the air outlet pipe 11 is closed by the switch cone ring 19, disconnecting the output channel of the hot air, and allowing the hot air to circulate inside the deodorization barrel 1 for deodorization. By providing an external circulation unit, the switch air hole 1901 will be rotated to a position where it is docked with the three exhaust pipes 20 after being misaligned with the air outlet pipe 11. , so that the exhaust pipe 20 is connected to the interior of the deodorizing barrel 1. At this time, the three-way valve 4 disconnects the first air duct 5 from the rectifier box 3, so that the circulation pump 24 is connected to the three-way valve 4, and then the hot air conveying device 2 stops conveying hot air, and is pumped by the circulation pump 24. After deodorization, the hot air is conveyed to the C-shaped tube 22 through the three exhaust pipes 20, and then is extracted into the first air duct 5 through the external circulation pipe 23 and the circulation pump 24 for circulation transportation, realizing the external circulation of the hot air, increasing the number of circulations of the hot air, thereby improving the emission of harmful substances by the hot air and improving the deodorizing effect. By setting the internal circulation unit, when the exhaust pipe 20 is connected to the switch air hole 1901, the switch air pipe 27 at the bottom end of the sled-shaped internal circulation pipe 26 will be docked with the other end of the switch air hole 1901, so that the hot air can only The hot air enters the skid-shaped inner circulation pipe 26 through the opening bent at the top of the skid-shaped inner circulation pipe 26, and then enters the external circulation through the switch air hole 1901, so that the hot air is internally circulated in the deodorizing barrel 1 through the first diffusion bucket 6, the stirring rod 18, and the switch air pipe 27, further improving the diffusion range of the hot air and ensuring the deodorizing effect. By setting the auxiliary circulation pipe 28, the auxiliary circulation pipe 28 adds multiple air inlets evenly distributed from top to bottom to the skid-shaped inner circulation pipe 26, so that the hot air can flow into the skid-shaped inner circulation pipe 26 from the top of the skid-shaped inner circulation pipe 26 and the bottom of the auxiliary circulation pipe 28 simultaneously, playing a guiding role in the internal circulation of the hot air, so that the hot air circulates and surges in each layer of the material, accelerating the dispersion of harmful substances. By setting the switch plate rack 29, when the hot air circulation time is sufficient,The stirring rod 18 drives the switch cone ring 19 to rotate in the opposite direction at the same angle, so that the exhaust pipe 20 and the switch air pipe 27 are both blocked. At the same time, the switch plate frame 29 moves synchronously to the bottom end of the auxiliary circulation pipe 28 to block the auxiliary circulation pipe 28. At this time, the hot air cannot circulate inside and outside through the skid-shaped internal circulation pipe 26, and the air outlet pipe 11 is re-connected with the interior of the deodorization barrel 1. The deodorized hot air is discharged through the air outlet pipe 11, completing the initial deodorization of the material. After that, the three-way valve 4 reconnects the rectifier box 3 with the first air duct 5, and the hot air conveying equipment 2 continues to convey hot air for a new round of deodorization. By setting the docking pipe 34, when exhausting, the hot air is transported to the inside of the air outlet track 32 and the air outlet slip ring 33 through the air outlet pipe 11, and then docked. The pipe 34 is discharged into the exhaust pipeline. The air outlet slip ring 33 can rotate inside the air outlet track 32, thereby adjusting the position and direction of the docking pipe 34, so that the hot air outlet can be freely adjusted to meet different production needs. By setting the first diffuser 6 of the rectifier box 3, after adjusting the position of the docking pipe 34, the sandwich flange 35 is sleeved on the sandwich flange 35, so that the sandwich flange 35 and the flange of the docking pipe 34 are docked.
