DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model.

[0028] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a non-woven fabric production heating device, comprising: drying oven and drying structure.

[0029] Drying oven includes box 10, exhaust fan 11 fixedly installed in the top wall in box 10, exhaust pipe 12 fixedly installed in the exhaust end of exhaust fan 11, and hollow guide pipe 14 and guide roller 13 fixedly installed in the inner wall of box 10 respectively, exhaust pipe 12 is used to discharge gas in box 10, rubber baffle 40 is fixedly installed in both ends of box 10, rubber baffle 40 can avoid that heat in box 10 is lost in large quantities from both sides of box 10.

[0030] There are multiple guide rollers 13 and hollow guide tubes 14. The multiple guide rollers 13 and hollow guide tubes 14 are staggered inside the box 10. The multiple guide rollers 13 are located on the left side of the multiple hollow guide tubes 14. An operation window 50 is opened on the front of the box 10, and a sealing plate 51 is fixed to the inner wall of the operation window 50 by bolts. The operation window 50 can be exposed by opening the sealing plate 51. When the non-woven fabric enters the box 10 from the left side, the operator can overlap the non-woven fabric on the multiple guide rollers 13 and hollow guide tubes 14 in the operation window 50 to form an "S" shaped fabric path. Then the non-woven fabric is led out from the right side of the box 10, thereby extending the travel distance of the non-woven fabric in the box 10 and achieving multi-sided heating in a limited space.

[0031] The drying structure includes a sleeve 20, an air inlet pipe 21 fixedly installed on the inner wall of the sleeve 20, a connecting pipe 22 fixedly installed on the right end of the air inlet pipe 21, a heat source fan 23 fixedly installed on the back of the connecting pipe 22, and a flow guiding component set on the back of the heat source fan 23. The flow guiding component includes a flow guiding pipe 30 fixedly installed on the exhaust end of the heat source fan 23, and an exhaust port 31 equidistantly opened on the left side of the hollow guide pipe 14. A U-shaped frame 60 is fixedly installed on the lower surface of the housing 10, and the sleeve 20 is located inside the U-shaped frame 60. The U-shaped frame 60 can support the sleeve 20 and improve the stability of the sleeve 20.

[0032] The other end of the guide pipe 30 is connected to the interior of the hollow guide pipe 14, and the exhaust port 31 is connected to the interior of the hollow guide pipe 14. Both the air inlet pipe 21 and the hollow guide pipe 14 are made of copper pipes. The heat source fan 23 can drive the external air into the heat source fan 23 along the air inlet pipe 21 and the connecting pipe 22. The heat source fan 23 can heat the air. The heated air will enter the hollow guide pipe 14 along the guide pipe 30 and be discharged into the box 10 along the exhaust port 31, thereby heating the non-woven fabric in the box 10. At this time, the hollow guide pipe 14 will also be heated. When the non-woven fabric passes through the hollow guide pipe 14, the surface temperature of the hollow guide pipe 14 will increase after being heated. When the non-woven fabric is in direct contact with the hollow guide pipe 14, conduction heat exchange occurs. The double effect is superimposed to improve the drying efficiency.

[0033] The surface of the sleeve pipe 20 is provided with a heat preservation layer, the sleeve pipe 20 and the air inlet pipe 21 are provided with a cavity 24, the lower end of the air outlet pipe 12 and the inside of the cavity 24 are communicated with each other, the inner right side wall of the cavity 24 is provided with an air flow outlet, and the inner left side wall of the cavity 24 is closed. After the heated air enters the box body 10 to heat the non-woven fabric, the air containing steam in the box body 10 can enter the cavity 24 along the air outlet pipe 12 under the driving of the air exhaust fan 11 and be discharged from the right side air flow outlet of the cavity 24. When the air containing steam passes through the cavity 24, the surface of the air inlet pipe 21 can be heated. Therefore, when the external air passes through the air inlet pipe 21, the external air can be preliminarily heated, so that the steam and part of the heat can be recycled, the energy consumption of the heat source fan 23 is reduced, and efficient recycling of heat energy is realized.

[0034] Specifically, the working principle and operation method of the utility model are as follows:

[0035] S-shaped cloth surface path optimization: the non-woven fabric passes through the staggered arrangement of the guide roller 13 and the hollow guide pipe 14 to form an "S" shaped path.

[0036] Air heating stage: the heat source fan 23 inhales external air, and the air is heated to a set temperature through the air inlet pipe 21→the connecting pipe 22→the heat source fan 23.

[0037] Non-woven fabric drying: the hot air is injected into the inside of the hollow guide pipe 14 through the flow guide pipe 30, and a uniform hot air curtain is formed through the equidistantly distributed air outlets 31. The high-temperature airflow is sprayed out of the air outlet 31, directly penetrates the non-woven fabric fiber layer, and rapidly evaporates the moisture.

[0038] Metal conduction heating: the surface temperature of the copper hollow guide pipe 14 rises after being heated, and the non-woven fabric is heated by heat conduction when being in contact with the copper hollow guide pipe 14.

[0039] Wet and hot waste gas collection: the air exhaust fan 11 guides the air containing steam to the cavity 24 between the sleeve pipe 20 and the air inlet pipe 21 through the air outlet pipe 12. The waste gas exchanges heat with the copper air inlet pipe 21 in the cavity 24. When the external air enters, the air is preheated. The preheated air is heated by the heat source fan 23 again, the energy consumption required for the target temperature rise is reduced, the low-temperature waste gas completing heat exchange is discharged from the right side of the cavity 24, and the heat pollution is reduced.

[0040] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and concept of the utility model, which should be covered in the protection scope of the utility model.
