Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrugated pipe processing, specifically a drying device for corrugated pipe processing. Background Technology
[0002] A drying device for corrugated pipe processing is a specialized piece of equipment used during the production of corrugated pipes to remove surface or internal moisture and improve the drying quality of the product. Its core function is to ensure that the corrugated pipes meet the required drying standards before subsequent processing, such as shaping, coating, or packaging. The corrugated pipe drying device uses heat transfer, such as hot air, infrared radiation, or steam, to evaporate or separate moisture from the surface or interior of the corrugated pipe, achieving a rapid and uniform drying effect. It removes residual moisture from the corrugated pipe forming, cleaning, or cooling processes, preventing oxidation, corrosion, or processing defects caused by moisture.
[0003] Patent CN220728789U discloses a drying device for corrugated pipe processing. The drying chamber has a heat conveyor at its bottom interior, with a conveying pipe attached to the heat conveyor. The end of the conveying pipe is connected to a supporting rod. A first rotating shaft is located on the proximal side wall of the supporting rod. The heat conveyed by the heat conveyor is transferred to the first rotating shaft via the supporting rod. The first rotating shaft has a driven block with multiple heat outlet holes communicating with the first rotating shaft. Depending on the specific size of the corrugated pipe, a telescopic rod can extend to fix an arc-shaped abutment plate against the inner wall of the corrugated pipe. The rotation of the first rotating shaft ensures that the entire corrugated pipe body is heated and dried. The heat outlet holes on the driven block allow for the dissipation of hot air, further drying the interior of the corrugated pipe.
[0004] The existing drying device uses the rotation of the first rotating shaft to heat and dry the body of the bellows. The driven block is equipped with heat outlet holes to release hot air to dry the inside of the bellows. However, when hot air is sprayed into the surface of the bellows for drying, the water on the surface of the bellows is heated and turns into water vapor. If the water vapor is not dealt with in time, it will re-adhere to the surface of the pipe, resulting in incomplete drying of the pipe. Utility Model Content
[0005] The purpose of this utility model is to provide a drying device for corrugated pipe processing, so as to solve the problems mentioned in the background art and overcome its technical defects.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0025] An embodiment of the present invention is shown in conjunction with the accompanying drawings.
[0026] Please see Figures 1 to 4A drying device for corrugated pipe processing includes a device housing 1, a fixing member 2 connected to one side of the device housing 1, a circulation mechanism for circulating air on the right side of the fixing member 2, and a quick-release mechanism for splicing the device on the left side of the device housing 1.
[0027] The circulation mechanism includes a heating element 3, which is connected to the right side of the fixing element 2 via a pipe. A circulating air pump 31 is connected to one side of the heating element 3 via a pipe. A dust removal element 32 is connected to the input end of the circulating air pump 31. A filter screen 33 is installed vertically inside the dust removal element 32. A moisture absorption plate 34 is placed on the right side of the filter screen 33. Both ends of the moisture absorption plate 34 and the filter screen 33 are fixed with a locking block 35 that is slidably connected to the dust removal element 32. An electric heating wire 36 is fixed inside the heating element 3. A placement cavity 5 is opened inside the outer shell 1 of the device. The inner shell 4 of the device is placed inside the placement cavity 5. A fixing bracket 6 is welded to the inner wall of the fixing element 2 and fixedly connected to one end of the inner shell 4 of the device. Three sets of adjusting screws 8 are threadedly connected to the inner walls of the outer shell 1 and the inner shell 4 of the device. Ball bearings 9 are installed at the ends of the three sets of adjusting screws 8.
[0028] By adopting the above technical solution, the outer shell 1 of the device is placed in a suitable position. The corrugated pipe to be dried is placed horizontally into the placement cavity 5 between the outer shell 1 and the inner shell 4. The adjusting screws 8 on the outer shell 1 and the inner shell 4, in cooperation with the ball bearings 9, guide and limit the corrugated pipe, effectively reducing the possibility of pipe misalignment. The adjusting screws 8 can be turned with a tool to adjust the distance between the ball bearings 9 and the corrugated pipe, facilitating support and limiting of corrugated pipes of different diameters. The circulating air pump 31 is started, drawing air from inside the outer shell 1 and delivering it to the heating element 3. The air is heated by the heating wire 36 inside the heating element 3. The heated air then enters the fixing element 2 and then into the placement cavity 5 inside the outer shell 1. In the process, the inner and outer walls of the corrugated pipe are dried, and the hot air entering the inner shell 4 can be discharged through the vent 10 on the inner shell 4 to ensure the utilization effect of the hot air. The fixing bracket 6 on the fixing component 2 fixes the inner shell 4. The dried air is then drawn out by the circulating air pump 31, so that the moisture carried in the air is also sucked out. When passing through the dust removal component 32, the filter screen 33 can filter the dust and impurities in the air. The moisture absorption plate 34 is made of cotton fabric and lime, so that the moisture absorption plate 34 can dehumidify the moisture in the air, thereby effectively reducing the moisture in the air. Then, it is circulated and heated again, which can effectively reduce the re-adhesion of moisture to the surface of the corrugated pipe. The filter screen 33 and the moisture absorption plate 34 can be disassembled by the locking block 35 for easy replacement.
[0029] Specifically, such as Figures 1-4As shown, the quick-release mechanism includes a connector 7, which is movably connected to the left side of the device housing 1. A first magnet 71 is fixed to the side wall of the connector 7, and a second magnet 72, which is fixed to the device housing 1, is movably connected to the right side of the first magnet 71. A conveying pipe 73 is connected to the outer wall of the connector 7, and a connector 74, which is inserted and connected to the dust removal component 32, is connected to the end of the conveying pipe 73. Several ventilation holes 10 are equidistantly opened inside the inner housing 4 of the device.
[0030] By adopting the above technical solution, the connector 7 and the device housing 1 are connected, and the first magnet 71 and the second magnet 72 can limit the connection of the connector 7. The connector 74 on the conveying pipe 73 is inserted into the dust removal component 32 through the pipe to achieve the function of communication.
[0031] Working principle: The corrugated pipe to be dried is placed horizontally into the placement chamber 5. The adjusting screws 8 on the outer shell 1 and the inner shell 4, in cooperation with the ball bearings 9, guide and limit the corrugated pipe. The adjusting screws 8 can be turned with a tool to adjust the distance between the ball bearings 9 and the corrugated pipe, supporting and limiting corrugated pipes of different diameters. Then, the connecting piece 7 is connected to the outer shell 1. The connector 74 on the conveying pipe 73 is inserted into the dust removal component 32 through the pipe. The circulating air pump 31 is started to draw the air out of the outer shell 1 and deliver it to the heating component 3. The air is heated by the heating wire 36 in the heating component 3. The heated air enters the fixing component 2 and then enters the placement chamber inside the outer shell 1. In cavity 5, the inner and outer walls of the corrugated pipe are dried, and the hot air entering the inner shell 4 can be discharged through the vent 10 on the inner shell 4 to ensure the utilization effect of the hot air. The fixing bracket 6 on the fixing component 2 fixes the inner shell 4. The dried air is drawn out again by the circulating air pump 31, and the moisture carried in the air is also sucked out. When passing through the dust removal component 32, the filter screen 33 can filter the dust and impurities in the air, and the moisture absorption plate 34 can dehumidify the moisture in the air, thereby effectively reducing the moisture in the air. After circulating heating again, the moisture can be effectively reduced from adhering to the surface of the corrugated pipe again. The filter screen 33 and the moisture absorption plate 34 can be disassembled by the locking block 35.
[0032] The technical scope of this utility model is not limited to the content described above.
