[0016] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects of the utility model will be described in detail below in combination with the drawings and preferred embodiments.
[0017] Example 1:
[0018] As Figures 1-6The utility model discloses a kind of fabric drying device, including box 1, two layers of horizontal baffle 2 are arranged at interval in box 1 inside, horizontal baffle 2 between forming the drying cavity 4 for fabric to pass, inlet 7 and discharge outlet 8 are arranged on the side wall of box 1 on both sides of drying cavity 4, vertical baffle 3 is arranged between the top wall of box 1 and the horizontal baffle 2 in upper side, vertical baffle 3 is also arranged between the bottom wall of box 1 and the horizontal baffle 2 in lower side, two independent cavities are formed in the both sides of vertical baffle 3, the cavity of one end close to inlet 7 is return air chamber 6, the cavity of one end close to discharge outlet 8 is hot air chamber 5, there are air outlet hole 11 on the horizontal baffle 2 in the range of hot air chamber 5, return air port 19 is arranged on the horizontal baffle 2 in the range of return air chamber 6, return air port 19 is close to one end of inlet 7, heating box 13 is arranged on the side wall of box 1, heating element 28 is arranged in heating box 13, heating box 13 is communicated with hot air chamber 5, return air chamber 6 by pipeline 9, condenser 14 is arranged on the pipeline 9 between heating box 13 and return air chamber 6, and the condenser 14 is used for condensing moisture in air;Fan 15 is arranged on the pipeline 9 between heating box 13 and return air chamber 6.
[0019] In actual use, fabric enters the drying cavity 4 of box 1 from the inlet 7 of one end of box 1, and is finally output from the discharge outlet 8. In this process, when the air passes through the heating box 13, the heating element 28 heats it, and the heated hot air enters the hot air chamber 5. The hot air in the upper and lower hot air chambers 5 enters the drying cavity 4 through the air outlet hole 11. At this time, the hot air will impact on the fabric above the drying cavity 4, and the hot air will flow to the end of the inlet 7 in the drying box 1. This process can continuously dry the fabric. The fabric close to the end of the discharge outlet 8 contacts hot air output from the hot air chamber 5, so the humidity is lower, and the drying effect on the fabric is better. In the drying process, the moisture in the fabric evaporates into the hot air, so the humidity of the hot air gradually increases. However, the hot air moves from the end of the discharge outlet 8 to the end of the inlet 7 in the drying cavity 4, so it does not affect the drying effect of the fabric at the discharge outlet 8. The humidity of the air close to the end of the inlet 7 is the highest, and at this time, the air is sucked into the return air chamber 6 from the return air port 19. The air in the return air chamber 6 is transported to the condenser 14 by the pipeline 9. When the hot air with high humidity enters the condenser 14, the water vapor in the air condenses due to the cold, forming liquid water, so that the air is relatively dry. The air temperature after dehumidification is still higher than the ambient air temperature, so the energy consumption required for heating to the specified temperature in the heating box 13 is lower.
[0020] The heating element 28 in the heating box 13 can be an electric heating tube or a steam heating tube, which are known technologies and their specific structures are not described in detail.
[0021] In actual work, the air humidity near the discharge port 8 of the drying box 1 is always less than that near the inlet port 7, to ensure the reliability of drying. When different humidity or different thickness of the fabric is dried, the conveying speed of the fabric can be adjusted to ensure that the fabric is dried more completely and reliably.
[0022] The condenser 14 comprises a shell 23, water inlet box 24 and water outlet box 25 are arranged at the upper and lower ends of the shell 23 respectively, water inlet pipe 16 is arranged on the water inlet box 24, water outlet pipe 17 is arranged on the water outlet box 25, condensing cavity 26 is formed in the shell 23 between the water inlet box 24 and the water outlet box 25, and a plurality of hollow fins 27 are arranged in the condensing cavity 26, the hollow fins 27 are connected with the water inlet box 24 and the water outlet box 25, and the pipeline 9 between the heating box 13 and the return air cavity 6 is connected to the two ends of the condensing cavity 26 of the shell 23. The hot air with relatively high humidity flowing back from the return air cavity 6 enters the condensing cavity 26 of the condenser 14, and the inside of the fin 27 has flowing water, so the surface temperature of the fin 27 is low, so the hot air and the fin 27 will cause the water in the air to condense on the fin 27, and finally flow to the bottom of the condensing cavity 26 of the shell 23. A drain pipe 18 and a valve can be arranged at the bottom of the condensing cavity 26 of the shell 23 for intermittent drainage. The water in the hot air condenses on the fin 27, which reduces the water content in the air and reduces the humidity, achieving the purpose of dehumidification.
[0023] The pipeline 9 on both sides of the heating box 13 extends into the hot air cavity 5 and the return air cavity 6, the pipeline 9 in the hot air cavity 5 and the return air cavity 6 is arranged in the width direction of the hot air cavity 5 and the return air cavity 6, and a plurality of through holes are arranged on the pipeline 9 in the hot air cavity 5 and the return air cavity 6. The conveying direction of the fabric is the length direction of the hot air cavity 5 and the return air cavity 6, so the horizontal direction perpendicular to the conveying direction of the fabric is the width direction of the hot air cavity 5 and the return air cavity 6. The pipeline 9 enters the hot air cavity 5 and the return air cavity 6 from the side wall of the box 1, traverses the hot air cavity 5 and the return air cavity 6, and the end is closed. The pipeline 9 in the hot air cavity 5 and the return air cavity 6 is provided with a plurality of through holes, which can convey hot air to each part of the width direction of the hot air cavity 5, and each part of the width direction of the return air cavity 6 can return air to the pipeline 9, so that the air conveying is more uniform and stable, to improve the air circulation performance.
[0024] A plurality of groups of guide rollers are arranged on the side walls in the drying box body 1, and each group of guide rollers comprises two ventilation guide rollers 10, which are arranged in a vertical direction and have a gap corresponding to the horizontal height of the feeding port 7 and the discharging port 8. The ventilation guide roller 10 comprises a short shaft 20 arranged on the side wall of a shell 23, a rotating disc 21 arranged on the short shaft 20, and a plurality of support rods 22 arranged in a circumferential direction on the outer periphery of the two rotating discs 21. Since the hot air is input from the upper and lower sides of the discharging port 8 in the drying cavity 4, and the air is output from the end of the discharging port 8, the fabric is easily subjected to excessive fluctuation during the process. Therefore, according to actual requirements, the guide roller group is arranged in the drying cavity 4 to limit the fluctuation range of the fabric. The gap between the two ventilation guide rollers in each guide roller group corresponds to the positions of the feeding port 7 and the discharging port 8, and is basically at the same horizontal height. Meanwhile, the ventilation guide roller 10 is hollow, and the two rotating discs 21 and the support rods 22 therebetween are connected to facilitate air flow and not affect the drying effect of the fabric.
[0025] An arc-shaped air deflector 12 is arranged on the horizontal partition plate 2 corresponding to the hot air cavity 5, and the arc-shaped air deflector 12 is located in the drying cavity 4, and the upper end of the arc-shaped air deflector 12 is bent towards the feeding port 7.
[0026] The design of the arc-shaped air deflector 12 allows the airflow to flow from the end of the discharging port 8 to the end of the feeding port 7 inside the drying cavity 4. Meanwhile, the hot air output from the air outlet hole 11 on the side of the arc-shaped air deflector 12 close to the discharging port 8 can directly act on the fabric at the corresponding position to perform the final drying of the fabric, so as to ensure the drying effect of the output fabric. The hot air output from the air outlet hole 11 on the side of the arc-shaped air deflector 12 close to the feeding port 7 flows quickly to the side of the feeding port 7 under the action of the arc-shaped air deflector 12, thereby improving the pre-drying of the fabric close to the feeding port 7.
