Description

Technical Field

[0001] The utility model relates to the technical field of autoclaves, in particular to a vent regulating device for ensuring the temperature uniformity of an autoclave. Background Art

[0002] During the curing of composite materials, temperature control is extremely stringent, particularly ensuring temperature uniformity within the autoclave. Existing autoclaves suffer from uneven temperature distribution, particularly in long autoclaves. Driven by a fan and impeller, the medium within the autoclave circulates through an air duct. Due to its long effective length, the flow rate gradually decreases from front to back, concentrating heat primarily at the front, resulting in a significant temperature difference between the front, middle, and back.

[0005] Furthermore, the lower end of each side connecting plate is rotatably connected to the elongated adjustment plate, and each side adjustment plate is provided with an elongated adjustment hole, and each side adjustment hole is fixedly connected to the fixed plate at the lower end of each side through an adjusting bolt.

[0006] Furthermore, a rotating shaft is fixed to the middle portion of each blade, and both ends of each rotating shaft pass through the corresponding fixing plates on both sides.

[0007] Furthermore, the wind guide plate is fixed on the side wall of the wind guide tube device, one end of the wind guide tube device is connected to the cooling tube, the other end of the cooling tube is connected to the heating tube, and the other end of the heating tube is connected to the air suction cone device, and the tip of the air suction cone device is provided with an impeller driven by a fan.

[0008] Furthermore, the air guide tube device is located in the tank body, and the fan is fixed on the outside of the tank body.

[0009] Furthermore, the blades are gradually widened from top to bottom, and the distance between each pair of fixing plates is also gradually widened from top to bottom.

[0010] Furthermore, the width of all blades is greater than or equal to the width of the hollow opening.

[0011] Through the above arrangement, the utility model fixes the outer frame of the vent adjustment device to the middle part of the autoclave air guide device, and connects all the blades through the rotation of the connecting plate. All the blades swing together, and the opening degree of all the blades can be freely adjusted by moving the position of the adjustment plate. The flow rate is limited by the opening and closing angles of multiple groups of blades to adjust the temperature uniformity in the tank.

It can effectively ensure the temperature uniformity in the long autoclave, thereby meeting the strict requirements of composite materials for temperature control. BRIEF DESCRIPTION OF THE DRAWINGS
