[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5The utility model provides a technical solution: a base paper drying and dehumidifying device, comprising a drying box 1, a symmetrically arranged shaft roller 2 is rotatably connected at the middle position of the drying box 1, an exhaust pipe 3 is fixedly installed at the bottom of the drying box 1, an air pump 4 is fixedly installed on one side of the drying box 1, one end of the air pump 4 is fixedly connected to the exhaust pipe 3, an air collecting box 5 is fixedly installed on the end of the air pump 4 away from the exhaust pipe 3, a first filter plate 6 is fixedly installed on one side of the air collecting box 5, an air delivery pipe 7 is fixedly connected to the top of the air collecting box 5, and the end of the air delivery pipe 7 away from the air collecting box 5 It is fixedly connected to the top of the drying box 1, and an air heater 8 is fixedly installed on the drying box 1 near the top of the exhaust pipe 3. A baffle 9 is fixedly connected to the drying box 1 near the top of the air heater 8. A plurality of heat conducting plates 10 are fixedly connected to the top of the baffle 9. A guide groove 11 is provided at the bottom of the baffle 9. A symmetrically arranged second filter plate 12 is fixedly installed on the drying box 1 corresponding to the heat conducting plate 10. A through groove 13 is provided on one side of the drying box 1 near the baffle 9, and a storage box 14 is fixedly connected to the drying box 1 near the bottom of the through groove 13.

[0019] A conduit 15 is fixedly connected to one side of the bottom end of the storage box 14, and a switch valve 16 is fixedly connected to the conduit 15, which is convenient for collecting and storing condensed water. The baffle 9 is designed as an inclined structure, and the baffle 9 is arranged corresponding to the storage box 14, which is convenient for the baffle 9 to discharge the condensed water. The heat conducting plate 10 is evenly distributed on the top of the baffle 9, and the two ends of the heat conducting plate 10 are arranged corresponding to the second filter plate 12, which is convenient for air to be sucked in from the second filter plate 12 and transported to the storage box 14 after heat conduction by the heat conducting plate 10. The exhaust pipe 3 is designed as a bamboo ladder structure, and the exhaust pipe 3 is arranged corresponding to the air heater 8, which is convenient for air heating.

[0020] Specifically, when the utility model is used, when the base paper is conveyed by the shaft roller 2, the air heater 8 and the air pump 4 are started, the air pump 4 draws air from the first filter plate 6, and discharges it to the bottom of the base paper through the exhaust pipe 3, so as to dry and heat the base paper. When the moisture in the base paper is heated and evaporates to the baffle 9, the air pump 4 extracts the air from the top of the baffle 9 through the air pipe 7, so that the temperature of the baffle 9 is relatively low. When the steam meets the baffle 9 with a relatively low temperature, it condenses water droplets and releases heat. Since the baffle 9 is designed as an inclined structure, the condensed water droplets slide along the guide groove 11 toward the through groove 13. The water droplets slide into the storage box 14 through the through groove 13. At the same time, the heat released when the water droplets condense is transmitted to the heat conduction plate 10 by the baffle 9. Since the two ends of the heat conduction plate 10 are arranged corresponding to the second filter plate 12, the air drawn by the air pump 4 through the air pipe 7 passes through the gap of the heat conduction plate 10 to absorb the heat, and the air that absorbs the heat is transported to the air collecting box 5 along the air pipe 7, and then transported to the bottom of the air heater 8 through the air pump 4 and the exhaust pipe 3. The secondary heated air can effectively dry and heat the base paper, thereby improving the drying efficiency of the base paper and reducing the energy consumption required for drying the base paper.
