Description

TECHNICAL FIELD

[0001] The utility model relates to the sieve plate fixing device technical field of rectifying column, especially to sieve plate fixing device for rectifying column. BACKGROUND

[0002] Rectifying column is a tower type vapor-liquid contact device for rectification, which utilizes the different volatility of each component in the mixture, i.e. the different vapor pressure of each component at the same temperature, to transfer the light components in the liquid phase to the gas phase and the heavy components in the gas phase to the liquid phase, thereby achieving the purpose of separation. In rectifying column equipment, sieve plate column is one of the earliest structural forms, which has been used in production since 1832. At that time, the operation performance of sieve plate column was not well understood, and the unreasonable design of sieve plate column led to poor operation performance and poor stability, so it was not widely used. In the 1950s, researchers conducted extensive research on sieve plate column and obtained a large amount of experimental data. After in-depth study of the operation performance of sieve plate column, it was believed that sieve plate column was a well-performing equipment. The installation and removal of sieve plate of rectifying column also affect the use effect of rectifying column. The Chinese utility model patent with patent number CN212881108U discloses a high-efficiency energy-saving sieve plate for rectifying column. The both ends of the plate body are movably connected with movable clamping plates. The inner side of each movable clamping plate is provided with a fixed groove. A plurality of springs are connected between the inner side wall of the movable clamping plate and the inner wall of the fixed groove. The structure of the movable clamping plate and the fixed groove is matched, so that the movable clamping plate can be stretched and contracted in the fixed groove. When installing, the movable clamping plate is pressed inward to compress the springs, so that the movable clamping plate can be stably retracted into the fixed groove. Then, the sieve plate is placed on the inner side of the rectifying column wall. Since the inner wall of the rectifying column wall is provided with an arc-shaped clamping groove corresponding to the outer position of the movable clamping plate, the structure of the movable clamping plate and the arc-shaped clamping groove is matched, so that the sieve plate can be stably installed on the inner wall of the rectifying column wall. This makes the installation and removal more convenient, without the need for bolt fixation, improving the installation efficiency and facilitating the removal and cleaning.

[0003] The above device still has some problems when in use. The substances treated in the rectifying column are usually liquids. When used for a long time, the springs are constantly washed by the liquid and are very prone to rust. After the springs rust, their elasticity is lost. In the process of installing and removing the sieve plate, the springs cannot be compressed, and the movable clamping plate cannot be retracted into the arc-shaped clamping groove, causing difficulty in installing and removing the sieve plate.
