The polypropylene filter material first enters the interior of the fixed box 11 through the upper half of the guiding rod 12. Then the filter material approaches the upper positioning rod 13 near the left half and bypasses from the upper half of the upper positioning rod 13 at this position, and moves downward to the lower positioning rod 14 on the left half. The filter material winds around the right side of the lower positioning rod 14 at this position and moves to the lower part of the lower positioning rod 14. Then the filter material moves to the left and reaches the position of the avoiding rod 15, and then bypasses from the upper part of the avoiding rod 15, and successively passes through the left half and the lower half of the avoiding rod 15. The filter material moves towards the right half area of the fixed box 11 and approaches the tensioning rod 16, passes through the lower part area of the tensioning rod 16, and keeps moving to the right. At this time, it approaches the pulling-back rod 17. The filter material moves upward after passing through the lower part area of the pulling-back rod 17, and then passes through the right side area of the guiding rod 18. At this time, the filter material is controlled to move to the left and reaches the positions of the upper positioning rod 13 and the lower positioning rod 14 on the right half. The filter material moves downward after passing through the upper part area of the upper positioning rod 13 on the right half and successively passes through the left side area of the upper positioning rod 13 on the right half and the left side area of the lower positioning rod 14 in cooperation. Then the filter material is moved to the right and wound around the winding block 19. A motor is externally connected to the cylindrical rod of the winding block 19 for winding the filter material. Thus, the laying of the filter material path is completed.

[0021] The outer wall of the guiding rod 18 is rotatably connected to the inner wall of the fixed box 11, the outer wall of the lower positioning rod 14 is rotatably connected to the inner wall of the fixed box 11, and the outer wall of the fixed box 11 is fixedly connected to the outer wall of the soaking pool 4.

[0022] The singeing device 2 includes a fixing plate 21. A side wall inside the fixing plate 21 is fixedly connected with a ventilation box 22. An inner wall at the top of the ventilation box 22 is fixedly connected with an igniter 23. An inner wall of the ventilation box 22 is fixedly connected with a ventilation pipe 24. Above the ventilation box 22 is provided an air suction box 25. Above the air suction box 25 is provided a fan 27. An outer wall at the top of the air suction box 25 is fixedly connected with a concentration pipe 26. An outer wall at the top of the concentration pipe 26 is fixedly connected with a blowing pipe 28. And the inside of the concentration pipe 26 is communicated with the inside of the blowing pipe 28. Combustible gas is introduced into the ventilation box 22 through the ventilation pipe 24 and is ejected from the hole above the ventilation box 22. The igniter 23 is used to ignite the combustible gas to generate a high-temperature flame. At this time, the fan 27 blows air towards the concentration pipe 26 through the blowing pipe 28 and blows out from the ash discharging device 3 to generate negative pressure. At this time, due to the negative pressure condition, the concentration pipe 26 guides the air in the area below the air suction box 25 to enter, and the air suction box 25 generates suction force, making the flame stably eject upwards and difficult to flutter left and right. Thus, double-sided singeing treatment is performed on the passing polypropylene filter material.

[0023] The output end of the fan 27 is fixedly connected with the outer wall of the blowing pipe 28. The outer wall at the bottom of the fan 27 is fixedly connected with the outer wall of the fixed box 11. The outer wall of the fixed box 11 is fixedly connected with the outer wall of the fixing plate 21. The inner wall of the fixing plate 21 is slidably connected with the outer wall of the ventilation pipe 24. A side wall inside the fixing plate 21 is fixedly connected with the outer wall of the air suction box 25.

[0024] The ash discharging device 3 includes a double-headed bent pipe 31. The outer wall of the double-headed bent pipe 31 is fixedly connected with a straight pipe 32. A through hole 33 is opened in the wall of the straight pipe 32. One end of the straight pipe 32 far from the double-headed bent pipe 31 is fixedly connected with a connecting pipe 34. The outer wall at the bottom of the straight pipe 32 is fixedly connected with the inner bottom end of the immersion pool 4. One end of the double-headed bent pipe 31 far from the straight pipe 32 is fixedly connected with the outer wall of the blowing pipe 28. During the singeing process, the generated dust and impurities are inhaled by the air suction box 25 and enter the straight pipe 32 through the double-headed bent pipe 31. Since the straight pipe 32 is in the immersion pool 4 and is below the water surface, the through hole 33 in the wall of the straight pipe 32 can allow water to enter the straight pipe 32. The dust and impurities enter the water body under the action of wind pressure, are adsorbed and precipitated by the water, and are ejected from the straight pipe 32 under the push. The connecting pipe 34 then sends out the air flow that has been partially filtered and has not been discharged into the atmospheric environment through the through hole 33 to assist the air flow.

[0025] Working principle:

[0026] During use, the polypropylene filter material is guided by the guiding device 1 to pass through the singeing device 2 to complete the singeing operation. The guiding device 1 mainly consists of a fixed box 11, a guiding rod 12, a pair of symmetrically arranged upper positioning rods 13, a pair of symmetrically arranged lower positioning rods 14, an avoidance rod 15, a tensioning rod 16, a pulling-back rod 17, a guiding rod 18, and a winding block 19. The polypropylene filter material first enters the interior of the fixed box 11 through the upper half of the guiding rod 12. Then the filter material approaches the upper positioning rod 13 near the left half and bypasses from the upper half of the upper positioning rod 13 at this position, moving downward to the lower positioning rod 14 on the left half. The filter material winds around from the right side of the lower positioning rod 14 at this position and moves below this lower positioning rod 14. Then the filter material moves to the left and reaches the position of the avoidance rod 15, and then bypasses from the upper part of the avoidance rod 15, successively passing through the left half and the lower half of the avoidance rod 15. The filter material moves towards the right half area of the fixed box 11 and approaches the tensioning rod 16, passes through the lower part area of the tensioning rod 16, and maintains the direction of moving to the right. At this time, it approaches the pulling-back rod 17. The filter material moves upward after passing through the lower area of the pulling-back rod 17, and then passes through the right side area of the guiding rod 18. At this time, the filter material is controlled to move to the left and reaches the positions of the upper positioning rod 13 and the lower positioning rod 14 on the right half. The filter material moves downward after passing through the upper area of the upper positioning rod 13 on the right half and successively passes through the left side area of the upper positioning rod 13 on the right half and the left side area of the lower positioning rod 14 for cooperation. Then the filter material is moved to the right and wound around the winding block 19. The cylindrical rod of the winding block 19 is externally connected to a motor for winding the filter material. Thus, the laying of the filter material path is completed, keeping the filter material in the correct position, preventing it from shifting during transmission, and at the same time enabling both sides of the filter material to pass through both sides of the singeing device 2 respectively, so that a single singeing device 2 can simultaneously perform singeing processing on both sides of the filter material. The settings of the avoidance rod 15 and the tensioning rod 16 can adjust the path of the filter material to be far away when passing below the singeing device 2, avoiding continuous approach to the heating position of the filter material and preventing discoloration caused by rapid temperature rise. During this process, the filter material is tensioned by multiple rods, and both sides of the filter material are tensioned by multiple rods, thereby completing the calendering of the filter material. The guiding device 1 can ensure the stable and accurate transmission of the filter material in the device, improve the reliability and efficiency of the entire processing process, keep the filter material in good flatness and tension during the processing, and is beneficial to improving the quality of singeing and calendering;

[0027] The singeing device 2 includes a fixing plate 21, a ventilation box 22, an igniter 23, a ventilation pipe 24, a suction box 25, a central pipe 26, a fan 27, and a blowing pipe 28. Combustible gas is introduced into the ventilation box 22 through the ventilation pipe 24 and ejected from the upper hole of the ventilation box 22. The igniter 23 is used to ignite the combustible gas to generate a high-temperature flame. At this time, the fan 27 blows air towards the central pipe 26 through the blowing pipe 28 and blows out from the ash discharging device 3 to generate negative pressure. At this time, due to the negative pressure condition, the central pipe 26 guides the air in the area below the suction box 25 to enter, and the suction box 25 generates suction, making the flame spray stably upwards and difficult to flutter left and right. Then, double-sided singeing treatment is carried out on the passing polypropylene filter material. Since the high-temperature flame can quickly burn off the fluff on the surface of the filter material, making the surface of the filter material smoother, the singeing device 2 can efficiently remove the fluff on the surface of the filter material, improving the quality and performance of the filter material. The role of the fan 27 can make the flame more stable, ensuring the consistency of the singeing effect. At the same time, the design of the suction box 25 can also timely suck away the dust and impurities generated during the singeing process, keeping the working environment clean;

[0028] The ash discharging device 3 is composed of a double-headed bent pipe 31, a straight pipe 32, a through hole 33, and a connecting pipe 34. After the dust and impurities generated during the singeing process are sucked into by the suction box 25, they enter the straight pipe 32 through the double-headed bent pipe 31. Since the straight pipe 32 is in the immersion pool 4 and is below the water surface, the through hole 33 in the wall of the straight pipe 32 can allow water to enter the straight pipe 32. The dust and impurities enter the water body under the action of wind pressure, are adsorbed and precipitated by the water, and are ejected from the straight pipe 32 under the push. The connecting pipe 34 sends out the air flow that has passed through partial filtration and has not been discharged into the atmospheric environment through the through hole 33 to assist the air flow. The ash discharging device 3 can effectively handle the dust and impurities generated during the singeing process, avoiding pollution and damage to the environment and equipment caused by them. The design of the through hole 33 and the immersion pool 4 can achieve dust treatment, reducing the difficulty and cost of subsequent treatment.
