Description

Technical Field

[0001] This utility model relates to the technical field of paper drying, and in particular to a hot air circulation device for paper drying. Background Technology

[0002] Paper is produced continuously on a production line and requires drying during the process. This is typically achieved using methods such as the hot air hood disclosed in utility model patent CN218322098U and the hot air hood disclosed in utility model patent CN220685611U, which can accelerate the drying speed of paper.

[0003] However, during use, it was found that the existing drying equipment has a relatively simple structure, making it difficult to circulate the hot air, resulting in heat waste and inconvenience in cleaning the moisture in the hot air, which affects the drying effect and leads to poor practicality. Therefore, there is an urgent need for a paper drying hot air circulation device to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a paper drying hot air circulation device that uses a conveying mechanism to transport paper through a drying mechanism to dry the paper, and a dehumidification mechanism to remove moisture from the drying mechanism, thereby improving the practicality of the equipment.

[0005] This utility model discloses a paper drying hot air circulation device, which includes a conveying mechanism; it also includes a drying mechanism and a dehumidification mechanism, both of which are installed on the drying mechanism;

[0006] The conveying mechanism conveys the paper, the drying mechanism dries the paper, and the dehumidification mechanism removes moisture from the drying mechanism.

[0007] The paper is conveyed by a conveying mechanism and then passed through a drying mechanism for drying. At the same time, a dehumidification mechanism removes moisture from the drying mechanism, thereby improving the practicality of the equipment.

[0008] Preferably, the drying mechanism includes a drying chamber, a heater, an air jet pipe, and a circulation mechanism. The drying chamber has an inlet at its left end and an outlet at its right end. The heater is installed on the top of the drying chamber and has an inlet and an outlet. The outlet of the heater communicates with the interior of the air jet pipe. The air jet pipe is installed inside the drying chamber and has multiple sets of air jet nozzles. The circulation mechanism is installed on the drying chamber. One end of the paper is inserted into the drying chamber through the inlet and extends out through the outlet, passing through the middle of the air jet pipe. Simultaneously, the air is heated by the heater and then discharged into the air jet pipe, causing the air jet pipe to spray hot air onto the paper, drying it. The hot air in the drying chamber then enters the circulation mechanism, passes through the dehumidification mechanism, and then re-enters the heater, reducing heat waste and improving the practicality of the equipment.

[0009] Preferably, the circulation mechanism includes multiple sets of guide shafts, two sets of air supply pipes, an exhaust pump, an exhaust pipe, and a guide cap. The multiple sets of guide shafts are rotatably mounted in the drying chamber, and each set of guide shafts is provided with an exhaust passage. The two sets of air supply pipes are respectively installed at the front and rear ends of the drying chamber, and the front and rear ends of the multiple sets of guide shafts are rotatably connected to the two sets of air supply pipes. The exhaust pump is fixedly mounted on the drying chamber, and its intake port communicates with the interior of the drying chamber. The exhaust port of the exhaust pump communicates with the interior of the rear air supply pipe, and the front air supply pipe communicates with the interior of the dehumidification mechanism through the exhaust pipe. The guide cap is installed on the top of the exhaust pipe. The paper in the drying chamber is passed around the multiple sets of guide shafts from left to right. Then, the exhaust pump is turned on to discharge the hot air from the drying chamber into the multiple sets of guide shafts, allowing the multiple sets of guide shafts to work with the air jet pipes to dry the paper. Afterward, the multiple sets of guide shafts discharge the hot air into the dehumidification mechanism, thereby improving the practicality of the equipment.

[0010] Preferably, the dehumidification mechanism includes a dehumidification box, a rotating shaft, a drive motor, multiple sets of absorbent cotton, and multiple sets of rolling shafts. The exhaust pipe communicates with the interior of the dehumidification box, and the dehumidification box communicates with the inlet of the heater. The rotating shaft is rotatably mounted in the dehumidification box. The drive motor is fixedly mounted on the top of the dehumidification box, and the output shaft of the drive motor is connected to the top of the rotating shaft. Multiple sets of absorbent cotton are mounted on the rotating shaft, and the outer rings of the multiple sets of absorbent cotton are rotatably connected to the inner wall of the dehumidification box. The multiple sets of rolling shafts rotate. Installed in a dehumidification chamber, with multiple sets of rolling shafts located at the top and bottom of multiple sets of absorbent cotton; the exhaust pipe discharges hot air from the multiple sets of guide shafts into the dehumidification chamber, where the hot air passes through the multiple sets of absorbent cotton, which absorb the moisture in the hot air. At the same time, the drive motor is turned on, causing the rotating shaft to drive the multiple sets of absorbent cotton to rotate at high speed, while the multiple sets of rolling shafts roll the multiple sets of absorbent cotton, removing water from the multiple sets of absorbent cotton through centrifugal force and extrusion, thereby improving the practicality of the equipment.

[0011] Preferably, a liquid level sensor is installed inside the dehumidification box, and an electrically controlled valve is installed at the bottom of the dehumidification box. The height of the liquid level sensor is lower than the height of the exhaust pipe inside the dehumidification box. When the liquid level inside the dehumidification box is higher than the liquid level sensor, the electrically controlled valve opens to drain the water from the dehumidification box, thereby improving the practicality of the equipment.

[0012] Preferably, the conveying mechanism includes a support shaft and a winding shaft. The support shaft is rotatably mounted on the left end of the drying chamber, and the winding shaft is rotatably mounted on the right end of the drying chamber. The second drive motor is fixedly mounted on the right side of the drying chamber and provides power to the winding shaft. The paper is passed around the support shaft, then around multiple sets of guide shafts inside the drying chamber, and through the middle of the air jet pipe. The paper is then fixed onto the winding shaft. The second drive motor is turned on to rotate the winding shaft and roll up the dried paper, thereby improving the practicality of the equipment.

[0013] Preferably, the drying box is equipped with an observation window; this allows staff to observe the drying status of the paper inside the drying box, thereby improving the practicality of the equipment.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the paper is conveyed by the conveying mechanism, and then passes through the drying mechanism to dry the paper. At the same time, the dehumidification mechanism removes the moisture in the drying mechanism, thereby improving the practicality of the equipment. Attached Figure Description
