[0004] However, in the comparison patent CN207793351U, when the furnace door is opened, the staff needs to be near the furnace door continuously, and since the aging furnace is closed and has a large temperature difference with the outside, hot air will gush out towards the furnace door after opening, and since the temperature is high and concentrated, it is easy to cause harm to the nearby staff, resulting in that the material piece car is not safe to take out, and in the comparison patent CN207793351U, hot air passes through the ventilation holes with different diameters on the car plate to heat the material pieces, so that the bottom of the material pieces will be directly impacted by hot air, and then the hot air flows back and circulates upwards, so that the top of the material pieces is not directly impacted by hot air, thus causing uneven heating of the material pieces. SUMMARY
[0005] In order to solve the problems of hot air gushing out after the aging furnace is turned on, causing harm to nearby workers and uneven heating of the bottom and top of the material, this invention proposes a hot air circulation aging furnace with good protection.
[0006] The hot air circulating aging furnace of the present invention, which has good protective effect, is composed of an aging furnace body, a heater, an aging furnace door, a first motor, a guide plate, a material cart, a flow guiding component, and a feeding component. The heater is located on the top of the aging furnace body, the aging furnace door is hinged to one side of the aging furnace body, and the first motor is located on the other side of the aging furnace body. The guide plate is located inside the upper part of the aging furnace body, and the material cart is located inside the lower part of the aging furnace body. The top of the guide plate is connected to the aging furnace body through a connecting rod. The outer side of the guide plate and the aging furnace body form a main air duct. The flow guiding component is located above the material cart, and the feeding component is located on both sides of the material cart. The output end of the first motor passes through the side wall of the aging furnace body and is fixedly connected to the airflow circulation wheel, which is located inside the main air duct. Several ventilation holes are opened around the bottom of the material cart.
[0007] The present invention has the following beneficial effects:
[0008] 1. This invention, by setting up a flow-guiding component including a guide plate, a guide plate, a return air duct, and a return hole, allows hot air to flow towards the bottom of the material cart in the main air duct after the heater heats the material during use in the aging furnace. Then, the hot air gradually passes through vents of different diameters to impact the bottom of the material cart. Afterward, the hot air flows upward and is guided by the guide plate, causing the hot air to flow towards the top of the material along the guide plate, thereby impacting the top of the material and ensuring that the bottom and top of the material are heated evenly. Afterward, the hot air sinks and enters the return air duct, and finally flows back to the main air duct through the return hole, forming a circulation under the action of the rotating air duct.
[0009] 2. This invention, by setting up a feeding assembly including a second motor, lead screw, crossbar, and slot, allows workers to evacuate to a safe position after unlocking the aging furnace door when it is necessary to remove the material cart and the materials inside. After the two second motors are running, the lead screw rotates, allowing the crossbar to move along the two lead screws. As the crossbar moves, it pushes the material cart through the slot, thus pushing the material cart out of the aging furnace. After the aging furnace is opened, the hot gas will not cause harm to nearby workers, providing good protection and greater safety. Attached Figure Description

The heater 2 is located on the top of the aging furnace body 1, the aging furnace door 3 is hinged to one side of the aging furnace body 1, and the first motor 4 is located on the other side of the aging furnace body 1. The guide plate 5 is located inside the upper part of the aging furnace body 1, and the material cart 6 is located inside the lower part of the aging furnace body 1. The top of the guide plate 5 is connected to the aging furnace body 1 through a connecting rod 501. The outer side of the guide plate 5 and the aging furnace body 1 form a main air duct 7. The flow guiding assembly 8 is located above the material cart 6, and the feeding assembly 9 is located on both sides of the material cart 6. The output end of the first motor 4 passes through the side wall of the aging furnace body 1 and is fixedly connected to an airflow circulation wheel 401, which is located inside the main air duct 7. Several ventilation holes 601 are opened around the bottom of the material cart 6.
[0028] The flow diversion assembly 8 consists of a guide plate 801, a guide plate 802, and a return flow hole 804. The guide plate 801 is fixedly installed at the bottom of the flow guide plate 5, and a plurality of guide plates 802 are evenly distributed laterally on the bottom surface of the guide plate 801 along the length direction of the guide plate 801. A return flow channel 803 is formed between the guide plate 801 and the flow guide plate 5. A plurality of return flow holes 804 are provided on the side of the flow guide plate 5 near the aging furnace door 3, which are opened along the thickness direction of the flow guide plate 5.
[0029] The feeding assembly 9 consists of a second motor 901, a lead screw 902, and a crossbar 903. The two second motors 901 are located on the outside of the aging furnace body 1. The two lead screws 902 penetrate the side wall of the aging furnace body 1 and are respectively located on both sides of the material cart 6. The ends of the two lead screws 902 are respectively connected to the output ends of the two second motors 901. The material cart 6 has a slot 904 opened laterally on the side away from the aging furnace door 3. The crossbar 903 is laterally sleeved on the outer surface of the two lead screws 902 and locked in the slot 904.
[0030] Heat insulation pads 10 are provided on the outer wall and back of the aging furnace body 1. The guide plate 5 has an L-shaped cross-section, with a rounded end on the side near the aging furnace door 3, which fits against the inner wall of the aging furnace door 3. The other end of the guide plate 5 is interference-fitted with the top side of the material cart 6. One side of the guide plate 802 is inclined towards the material cart 6. One side of the return air duct 803 is connected to the main air duct 7 through the return hole 804, and the other side of the return air duct 803 is located on the top side of the material cart 6. The crossbar 903 matches the slot 904, and the crossbar 903 is connected to the lead screw 902 by a thread.
[0031] When the aging furnace body 1 is in use, after the heater 2 heats the material, the air circulation wheel 401 rotates to allow hot air to flow in the main air duct 7 toward the bottom of the material cart 6. Then, the hot air gradually passes through the ventilation holes 601 of different diameters to impact the bottom of the material cart 6.
[0032] After the hot air flows upward, it will be guided by the guide plate 801, so that the hot air flows along the guide plate 802 towards the top of the material, thereby impacting the top of the material and making the bottom and top of the material evenly heated. Then the hot air sinks and can enter the return air duct 803, and finally flows back to the main air duct 7 through the return hole 804, forming a circulation under the action of the airflow circulation wheel 401.
[0033] When it is necessary to remove the material cart 6 and the materials inside, the staff can evacuate to a safe position after unlocking the door lock of the aging furnace 3. Then, after the two second motors 901 are running, the lead screw 902 will rotate, allowing the crossbar 903 to move along the two lead screws 902. As the crossbar 903 moves, it can push the material cart 6 through the slot 904, thereby pushing the material cart 6 out of the aging furnace body 1. After the aging furnace is turned on, the hot gas will not cause harm to the nearby staff, and the protection effect is good and safer.
[0034] This embodiment, by setting up a flow-guiding component including a guide plate, a guide plate, a return air duct, and a return hole, allows hot air to flow towards the bottom of the material cart in the main air duct after the heater heats the furnace body during use. Then, the hot air gradually passes through vents of different diameters to impact the bottom of the material cart. Afterward, the hot air flows upward and is guided by the guide plate, causing the hot air to flow towards the top of the material along the guide plate, thereby impacting the top of the material and ensuring that the bottom and top of the material are heated evenly. Afterward, the hot air sinks and enters the return air duct, and finally flows back to the main air duct through the return hole, forming a circulation under the action of the rotating air duct.
[0035] This embodiment, by setting up a feeding assembly including a second motor, lead screw, crossbar, and slot, allows workers to evacuate to a safe position after unlocking the aging furnace door when it is necessary to remove the material cart and the materials inside. After the two second motors are running, the lead screw rotates, allowing the crossbar to move along the two lead screws. As the crossbar moves, it pushes the material cart through the slot, thus pushing the material cart out of the aging furnace. After the aging furnace is turned on, the hot gas will not cause harm to nearby workers, providing good protection and greater safety.
