Description

Technical Field

[0001] The utility model relates to the field of corrugated paper processing equipment, in particular to a corrugated paper continuous production and drying tunnel furnace. Background Art

[0002] Corrugated paper is a roll paper material made of pulp as raw material, and its structure presents a multi-layered wavy shape. In the production and processing of corrugated paper, a drying tunnel furnace is required. A heating mechanism is provided on the top of the tunnel furnace, and the corrugated cardboard is placed vertically in the fixing device. Due to the hardness of the corrugated cardboard itself as support, the corrugated cardboard will be in a vertical state between the two baffles and enter the tunnel furnace for drying.

[0003] When the existing corrugated paper continuous production drying tunnel furnace is drying the corrugated paper, the water vapor generated is gathered at the top of the drying tunnel furnace. Due to the lack of a mechanism to recycle hot air, the water vapor exists inside the drying tunnel furnace, which affects the drying efficiency of the corrugated paper. When the water vapor is directly discharged, the heat inside the drying tunnel furnace will be lost, which also affects the drying efficiency of the corrugated paper. Based on this, we proposed a corrugated paper continuous production drying tunnel furnace. Utility Model Content

[0023] In this embodiment, the water vapor at the top of the drying tunnel furnace body 1 is introduced into the connecting channel 2 through the circulation conveying mechanism, and the water molecules in the water vapor are stirred and filtered through the filtering mechanism, and then the filtered hot air is reintroduced into the drying tunnel furnace body 1 in conjunction with the circulation conveying mechanism. The hot air required for corrugated paper drying is guaranteed, and the hot air is circulated in this process to prevent the water vapor inside the drying tunnel furnace body 1 from affecting the drying efficiency of the corrugated paper.

[0024] Specifically, the circulation conveying mechanism includes a suction fan 6 , a mounting frame 4 is embedded at the top of the connecting channel 2 through bolts, a mounting plate 5 is fixedly connected to one side of the mounting frame 4 , and the suction fan 6 is installed on one side of the mounting plate 5 .

[0025] In this embodiment, the suction fan 6 is used to facilitate the water vapor gathered at the top of the drying tunnel furnace body 1 to be sucked into the connecting channel 2 for processing.

[0026] Specifically, one end of the connecting channel 2 away from the suction fan 6 is fixedly connected to the air outlet pipe 3, and one end of the air outlet pipe 3 is fixedly connected to the top of the drying tunnel furnace body 1.

[0027] In this embodiment, two air outlet pipes 3 are used to facilitate the introduction of filtered hot air into the interior of the drying tunnel furnace body 1 .

Then the motor 9 is started, so that the motor 9 drives the rotating rod 10 to rotate, so that the rotating rod 10 drives a number of extension plates 13 to rotate, and then the extension plate 13 drives the filter screen 12 to rotate. The extension plate 13 stirs the water vapor and cooperates with the filter screen 12 to filter the water molecules. Then the filtered hot air is reintroduced into the interior of the drying tunnel furnace body 1 through the two air outlet pipes 3 to ensure the hot air required for the drying of the corrugated paper. In this process, the hot air is circulated to prevent the water vapor inside the drying tunnel furnace body 1 from affecting the drying efficiency of the corrugated paper.

[0035] Secondly, when the corrugated paper is dried, the cover plate 17 is opened by bolts, and then the baffle plate 16 is rotated 90 degrees, so that the baffle plate 16 rotates on the stud 15. The inner side of the baffle plate 16 is away from one end of the extension plate 13, thereby releasing the restriction on the sliding plate 11. It is convenient for the staff to pull the sliding plate 11 out of the slot 14 and replace and clean the filter screen 12.
