[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] See also Figures 1 to 4A distillation column for hydrogen fluoride production includes: a column body 1, a tray 2, an operating box 3, a locking mechanism, a transmission mechanism, and a drive mechanism. The column body 1 has multiple through slots, and the tray 2 is disposed inside the column body 1. The operating box 3 is fixedly connected to each of the multiple through slots. Through the cooperation between the column body 1, the tray 2, the operating box 3, the locking mechanism, the transmission mechanism, and the drive mechanism, the tray 2 can be quickly and stably installed inside the column body 1. Furthermore, when the tray 2 needs to be disassembled for maintenance, it can be quickly disassembled and maintained, thus improving the efficiency of tray 2 maintenance.

[0047] Each of the multiple operating boxes 3 is equipped with a locking mechanism for locking the tower plate 2. The locking mechanism includes a locking plate 4, a clamping rod 5, a clamping block 6, a support plate 7, and a pushing assembly. The locking plate 4 is fixedly connected to the tower plate 2, the clamping rod 5 is rotatably connected to the operating box 3, the clamping block 6 is rotatably connected to the clamping rod 5, and the support plate 7 is fixedly connected to the operating box 3. The pushing assembly is located inside the operating box 3 and is used to push the clamping rod 5 to swing. The pushing assembly includes a sliding rod 8, a pushing wheel 9, and a transmission wheel 10. The sliding rod 8 is slidably located inside the operating box 3, the pushing wheel 9 is rotatably connected to the sliding rod 8 and contacts the clamping rod 5, and there are two transmission wheels 10, both of which are rotatably connected to the sliding rod 8. Specifically, the sliding rod 8 drives the pushing wheel 9 to move, which in turn drives the pushing wheel 9 to push against the clamping rod 5 and swing. When the clamping plate swings, it drives the clamping block 6 to clamp the locking plate 4 onto the operating box 3, and the support plate 7 supports the locking plate 4.

[0048] Each of the multiple operating boxes 3 is equipped with a transmission mechanism for driving the locking mechanism to move. The transmission mechanism includes: a sliding plate 11, a wedge block 12, a support shaft 13, and a linkage assembly. The sliding plate 11 is slidably disposed in the operating box 3, and the wedge block 12 is fixedly connected to the sliding plate 11 and contacts the transmission wheel 10. The support shaft 13 is rotatably connected in the operating box 3 and contacts the wedge block 12. The linkage assembly is disposed in the operating box 3 and is used to link the sliding plate 11 to move. The linkage assembly includes: a rotating screw 14 and a rotating gear 15. The rotating screw 14 is fixedly connected to the sliding plate 11, and the rotating gear 15 is rotatably connected to the operating box 3. The rotating gear 15 has a screw hole, and the rotating screw 14 is threaded into the screw hole. Specifically, the rotation of the rotating gear 15 drives the rotating screw 14 to move in the screw hole, thereby driving the sliding plate 11 and the wedge block 12 to descend. When the wedge block 12 descends, it supports the transmission wheel 10 to move, which in turn drives the slide bar 8 and the push wheel 9 to move.

[0049] The drive mechanism is mounted on the tower body 1 and is used to drive multiple transmission mechanisms to move. The drive mechanism includes a gear ring 16, a drive gear 17, and a first motor 18. The gear ring 16 is rotatably connected to the tower body 1 and meshes with the rotating gear 15. The drive gear 17 is rotatably connected to the gear ring 16 and meshes with the gear ring 16. The first motor 18 is mounted on the tower body 1 and its output end is fixedly connected to the drive gear 17. Specifically, the first motor 18 drives the drive gear 17 to rotate. When the drive gear 17 rotates, it drives the gear ring 16 to rotate. When the gear ring 16 rotates, it drives the rotating gear 15 to rotate, which in turn drives the rotating screw 14 to move within the screw hole.

[0050] In summary, when the pedal of the distillation column for hydrogen fluoride production is removed, the first motor 18 rotates in the reverse direction, driving the drive gear 17 and the gear ring 16 to rotate in the reverse direction, thereby driving the rotating screw 14 and the slide plate 11 to rise, which in turn drives the wedge block 12 to rise synchronously, thereby releasing the support on the transmission wheel 10 and the slide bar 8, thereby releasing the clamping force of the clamping rod 5 and the clamping block 6 on the locking plate 4, thus facilitating the quick removal of the pedal.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
