[0016] The structure of the present invention is further described below in conjunction with the accompanying drawings.
[0017] Reference Figures 1 to 3 An external adjustment device for an aromatic crystallizer corrugated jacket includes a sleeve 10 and a corrugated aromatic crystallizer corrugated jacket 20 arranged on the sleeve. The aromatic crystallizer corrugated jacket is fixedly connected to the sleeve through a corrugated jacket connecting portion 21 between adjacent corrugations. The adjustment device also includes a positioning member 30 and an adjustment member 40. The positioning member 30 is fixedly connected to the corrugated jacket connecting portion. The adjustment member 40 includes an arc plate 41 matched with the corrugated top surface of the corrugated jacket and a pressure rod 42 for pressing the arc plate and the corrugated jacket. The pressure rod is adjustably arranged on the positioning member.
[0018] In this embodiment, the positioning member 30 includes a support plate 31 and an Ω-shaped arc plate 32. The support plate is fixedly connected to the corrugated jacket connection portion. The Ω-shaped arc plate is located on the support plate. The support plate 31 is provided with a support platform 311 that matches the bottom plane of the Ω-shaped arc plate. The Ω-shaped arc plates are evenly arranged along the circumference to form a circular ring. The support platform supports the bottom plane of the Ω-shaped arc plate. The Ω-shaped arc plates are evenly arranged along the circumference to form a circular ring, so that the Ω-shaped arc plate as a whole forms a stable circular self-clamping. Therefore, the overall structure is simple and easy to install.
[0019] In this embodiment, the radial cross-section of the support plate 31 is an inverted V-shaped structure, and the two sides of the inverted V-shaped structure of the support plate are fixedly connected to the corrugated jacket connection part, and the two sides of the inverted V-shaped structure of the support plate can be connected to the corrugated jacket connection part by welding. In specific implementation, it can also be fixedly connected by screws or connected in other ways. The two sides of the length direction of the support plate are inclined surfaces, the support platform is located in the middle of the inclined surface of the support plate, and the arc surface of the Ω-shaped arc plate is above the top of the support plate. During installation, the two sides of the inverted V-shaped structure are welded to the corrugated jacket, and the arc surface of the Ω-shaped arc plate is covered on the support plate so that the bottom plane of the Ω-shaped arc plate is located on the support platform, which is simple and convenient to install.
[0020] In this embodiment, the platforms on both sides of the bottom of the Ω-shaped arc plate are provided with equally spaced adjustment holes corresponding to the corrugated jacket. The pressure rod 42 is a bolt, the adjustment hole is a bolt through hole, and the bolts on both sides of the adjustment hole are provided with adjustment nuts 43. Through the adjustment of the bolt and the nut, the bolt presses the arc plate on the outside of the corrugated jacket, thereby adjusting the geometric shape of the corrugated jacket and supporting the corrugated jacket. In specific implementation, the pressure rod can also be a screw rod, and the adjustment hole is a threaded hole that cooperates with the screw rod. The screw rod can be adjusted to press the arc plate on the outside of the corrugated jacket.
[0021] The positioning piece of the external adjustment device of the corrugated jacket of the aromatic hydrocarbon crystallizer of the present invention is fixedly connected to the corrugated jacket connection part, and the pressure rod is adjustably arranged on the positioning piece. The arc plate and the corrugated jacket can be pressed tightly by adjusting the pressure rod so that the corrugated jacket can be restored to its original shape, so that the corrugated jacket can maintain uniformity and rigidity. After the crystallizer is assembled or operated for a period of time, the external shape of the corrugated jacket is observed, and the corrugated jacket with a changed external geometric shape is adjusted to ensure the uniformity and rigidity of its channel.
