Description

Technical Field

[0001] This utility model belongs to the field of wood fire door production technology, and in particular relates to a wood drying equipment for wood fire door production. Background Technology

[0002] Fire doors are typically installed on firewalls, at stairwell entrances, or at pipe shaft openings, playing an important role in reducing fire damage. Wooden fire doors are fire doors made of wood or wood products.

[0003] Utility model patent CN216347611U discloses a wood drying device for the production of fireproof wooden doors, including a drying chamber with an inlet and an outlet on both sides. A pair of symmetrically distributed heating plates are provided on the inner wall of the drying chamber, and the heating plates are slidably connected to the inner wall. An adjustment component is provided inside the drying chamber to adjust the distance between the pair of heating plates. A set of support legs is fixed to the bottom of the drying chamber. Baffles made of rubber are fixed to the upper and lower side walls of both the inlet and outlet. This device does not preheat the wood, thus failing to eliminate internal stress, making it prone to sudden heating and cracking. Furthermore, it generates moisture during heating, increasing the humidity inside the chamber and affecting the drying quality of the wood. Therefore, a wood drying device for the production of fireproof wooden doors is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a wood drying device for the production of wooden fire doors, so as to solve the problems mentioned in the background art.

[0005] A wood drying device for producing fireproof wooden doors includes a fixed plate, a conveyor frame fixedly connected to the fixed plate, a first reinforcing frame fixedly connected to the conveyor frame, a drive motor fixedly mounted on the first reinforcing frame, a rotating shaft connected to the output shaft of the drive motor, a first conveyor wheel rotatably connected to the conveyor frame, the first conveyor wheel connected to the rotating shaft, a second conveyor wheel rotatably connected to the conveyor frame, a conveyor belt connected between the first and second conveyor wheels, multiple support frames fixedly connected to the conveyor belt, a first drying chamber fixedly connected to the conveyor frame, multiple heaters installed in the first drying chamber, a first temperature sensor installed in the first drying chamber, a second drying chamber fixedly connected to the conveyor frame, multiple heating tubes installed in the second drying chamber, a second temperature sensor installed in the second drying chamber, a humidity sensor installed in the second drying chamber, a second reinforcing frame fixedly connected to the second drying chamber, an exhaust fan fixedly mounted on the second reinforcing frame, an exhaust fan connected to an exhaust pipe, and an exhaust hood connected between the exhaust fan and the second drying chamber.

[0006] Furthermore, multiple auxiliary rotating rollers are installed on the conveyor frame.

[0007] Furthermore, a beveled block is fixedly connected to the fixed plate.

[0008] The beneficial effects of this utility model are:

[0009] 1. This utility model heats wood by using heat generated by a heater. A first temperature sensor detects the heat generated by the heater, controlling the heat at 40℃-50℃, thereby preheating the wood, heating it evenly, eliminating internal stress, and preventing cracking due to sudden heating.

[0010] 2. This utility model uses the heat generated by the heating tube to reheat the wood. The second temperature sensor detects the temperature inside the second drying chamber, and the humidity sensor detects the humidity inside the second drying chamber. This allows the temperature to gradually rise to 60℃-70℃ and the humidity to drop to 50%-60%, accelerating the evaporation of moisture. The air extractor extracts the evaporated water vapor, which is then discharged through the air suction hood and air delivery pipe to prevent water vapor from interfering with the operation of the heating tube.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1 to 4The wood drying equipment for producing fireproof wooden doors shown in this utility model includes a fixed plate 1, a conveyor frame 2 fixedly connected to the fixed plate 1, a first reinforcing frame 3 fixedly connected to the conveyor frame 2, a drive motor 4 fixedly mounted on the first reinforcing frame 3, a rotating shaft 5 connected to the output shaft of the drive motor 4, the rotating shaft 5 being rotatably connected to the conveyor frame 2, a first conveyor wheel 6 rotatably connected to the conveyor frame 2, the first conveyor wheel 6 being connected to the rotating shaft 5, a second conveyor wheel 7 rotatably connected to the conveyor frame 2, a conveyor belt 8 connecting the first conveyor wheel 6 and the second conveyor wheel 7, a plurality of support frames 9 fixedly connected to the conveyor belt 8 for carrying wood, and a first drying chamber 11 fixedly connected to the conveyor frame 2. Multiple heaters 12 are installed on the first drying box 11. The heaters 12 are used to heat and dry the wood. A first temperature sensor 13 is installed on the first drying box 11. A second drying box 14 is fixedly connected to the conveyor frame 2. Multiple heating tubes 15 are installed on the second drying box 14. The heating tubes 15 are used to heat and dry the wood. A second temperature sensor 16 is installed on the second drying box 14. A humidity sensor 17 is installed on the second drying box 14. A second reinforcing frame 18 is fixedly connected to the second drying box 14. An exhaust fan 19 is fixedly installed on the second reinforcing frame 18. The exhaust fan 19 is used to extract steam. An air supply pipe 20 is connected to the exhaust fan 19. An air suction hood 21 is connected between the exhaust fan 19 and the second drying box 14.

[0018] Multiple auxiliary rotating rollers 10 are installed on the conveyor frame 2.

[0019] An inclined block 22 is fixedly connected to the fixed plate 1.

[0020] The working principle of this utility model is as follows: After the wood is placed on the support frame, the drive motor will drive the rotating shaft, the first conveyor wheel, the second conveyor wheel and the conveyor belt to rotate. The conveyor belt will transport the support frame and the wood. When the wood is transported into the first drying box, the drive motor will stop working. The heat generated by the heater will heat the wood. The first temperature sensor will detect the heat generated by the heater and control the heat at 40℃-50℃, thereby preheating the wood, heating the wood evenly, eliminating internal stress and avoiding sudden heat cracking.

[0021] After the wood is preheated, the drive motor continues to rotate the shaft, the first conveyor wheel, the second conveyor wheel, and the conveyor belt, causing the wood to leave the first drying chamber. Once the wood is transported to the second drying chamber, the drive motor stops, and the heat generated by the heating element reheats the wood. The second temperature sensor detects the temperature inside the second drying chamber, and the humidity sensor detects the humidity inside the second drying chamber, gradually increasing the temperature to 60℃-70℃ and reducing the humidity to 50%-60%, accelerating moisture evaporation. The exhaust fan extracts the evaporated water vapor, allowing it to be discharged through the suction hood and air pipe to prevent water vapor from interfering with the operation of the heating element. After the wood is dried, the conveyor belt transports the wood out of the second drying chamber. As the wood is turned over, it falls onto the inclined block and slides down the inclined block.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
