One side of the straight pipe 11 is connected to the air supply pipe 12, and the other side of the air supply pipe 12 is connected to the side of the inert gas storage box 13 installed at the lower part of the support leg 5. A rotating mixing part is provided inside the straight pipe 11, and the rotating mixing part passes through the air guide pipe 10.

[0026] The inert gas storage box 13 has a support plate 21 at its bottom, and the side of the support plate 21 is fixed to the lower side of the support leg 5. The bottom of the gas guide pipe 10 is fixedly installed on the top side of the support plate 21 by a retaining block 22. The bottom of the support plate 21 has an L-shaped seat 23, and the bottom of the L-shaped seat 23 has a base plate 24. The base plate 24 is fixedly installed at the lower part between the support legs 5. The shell 2 is a sealed shell. An interlayer is formed between the inner wall of the shell 2 and the porous distribution sleeve 15. Nitrogen gas is introduced into the interlayer. The two ends of the dust collector bag 19 are sealed to the transverse explosion-proof plate 17 and the top and bottom of the porous distribution sleeve 15 by clamps.

[0027] In addition, the spiral guide section includes a guide plate 25, which has several guide grooves 26. Each guide groove 26 has an expansion groove 27 between adjacent guide grooves.

[0028] By incorporating a spiral guide section, the problem of dust accumulation and blockage can be solved. Compared to the existing single spiral rod, it is less prone to dust entanglement and localized bridging. This invention generates radial centrifugal force through the rotation of the guide plate 25, several guide channels 26, and expansion channels 27, dispersing dust into multiple guide channels 26. The expansion channels 27 further expand the distribution space. Combined with the axial conveying force of the spiral rod 28, dust flows without dead zones, thereby reducing the accumulation and blockage rate. Compared to the existing simple spiral structure, this structure effectively avoids the disorderly impact of large dust particles, thus reducing the wear of the inner wall.

A sleeve 53 is provided on the side of disc 1 52 away from U-shaped clamping block 7 51. Several blades 5 are provided on the other side of sleeve 53. 4. A cylinder 59 is sleeved on the outside of the rotating shaft 55. An L-shaped frame 58 is provided on one side of the cylinder 59. The side of the L-shaped frame 58 is fixed to the inner wall of the straight pipe 11. A second disc 57 is provided on the top of the rotating shaft 55. A bent pipe 56 is provided on the outside of the second disc 57. The bent pipe 56 extends into the gas guide pipe 10. The second disc 57 is embedded in the right outlet end of the bent pipe 56. Expanded graphite sealing strips are provided on the contact surfaces of the transverse explosion-proof plate 17 and the longitudinal explosion-proof plate 16 with the inner wall of the porous distribution sleeve 15.

[0030] By setting up a rotating mixing section, the inert gas and the dust-laden gas can be rapidly diffused and merged, shortening the mixing time. In the existing simple mixing structure, the airflow after mixing will randomly impact the filter plate, resulting in a low interception rate of large particles and easy wear of the filter plate. The bend 56 in the rotating mixing section extends into the air guide pipe 10, and guides the mixed airflow to hit the filter plate 14 at an angle when rotating, which improves the interception rate of large particles and reduces the impact wear of the airflow on the filter plate 14.

[0031] Detailed usage and function of this embodiment: Before starting the equipment, nitrogen from the inert gas storage tank 13 is injected into the interlayer formed by the shell 2 and the porous distribution sleeve 15 through the gas flow control valve on the gas supply pipe 12. The pressure inside the interlayer is monitored by a pressure sensor to ensure that the oxygen concentration inside the shell 2 is maintained within the specified value. Dust-laden gas is introduced into the gas guide pipe 10, and the gas supply pump installed on the gas supply pipe 12 is started to transport the inert gas from the inert gas storage tank 13 to the straight pipe 11 through the gas supply pipe 12. The second motor 34 is started and runs. The second motor 34 drives the first U-shaped clamp 35 to rotate, the first U-shaped clamp 35 drives the second U-shaped clamp 38, and further, the third U-shaped clamp 40 drives the fourth U-shaped clamp 43 to rotate, and so on. The blades 54 rotate, and the bent pipe 56 also rotates together. Therefore, the bent pipe 56 and the blades 54 form a vortex rotation motion in the air guide pipe 10, which uniformly mixes the inert gas introduced into the air supply pipe 12 with the dust-laden gas entering into the air guide pipe 10. The mixed gas impacts the filter plate 14 in a directional manner, and the filter plate 14 intercepts large particles of impurities. The pre-filtered gas is driven by the conveying propeller in the inverted conical feed hopper 6, and enters the housing 2 through the connecting pipe 8 and the feed pipe 9. It passes through the pores of the porous distribution sleeve 15 and enters each independent dust removal unit 18. The dust removal bag 19 filters the fine dust particles in the gas, and the purified gas is discharged from the air outlet 4 through the fan box 3. The housing 2 has a porous distribution sleeve 15 inside, which forms an interlayer with the inner wall of the housing 2. The interlayer forms a flow guide cavity. The inner wall of the flow guide cavity is a porous ceramic plate, and the outer wall of the flow guide cavity is a flexible explosion-proof membrane. A spiral flow guide plate can be installed on the inner wall of the flow guide cavity to guide the high-temperature gas to be ejected at a preset angle during pressure relief, so as to avoid direct impact on surrounding equipment or dust accumulation areas. The surface of the flow guide plate is coated with a high-temperature resistant ceramic coating to prevent high-temperature ablation. The dust generated during filtration falls into the inverted conical hopper 7 under gravity. The motor 29 is started and runs, driving the screw 28 to rotate. The rotation of the screw 28 drives the guide plate 25 to rotate. After the guide plate 25 rotates, it guides the particulate dust generated in the shell 2 into the guide groove 26 and the expansion groove 27, and then transports it to the lower part of the inverted conical hopper 7. As the screw 28 rotates, the dust is rolled down and then enters the screen 31. Since the screen 31 also rotates with the screw 28, the particulate dust entering the screen 31 will be screened out by the screen 31. The dust containing particles is screened out and remains in the screen, while the powder falls from the bottom of the inverted conical hopper 7 and re-enters the air guide pipe 10.

[0032] A filter membrane made of high-temperature resistant material is installed at the discharge port 33. The filter membrane is connected to the air guide pipe 10 through a return pipe at the discharge port at the bottom of the inverted conical discharge hopper 7. The inverted conical discharge hopper 7 and the support plate 1 are installed using a detachable structure.

[0033] Through the specific embodiments described above, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
