[0002] A fractionation tower is a tower-type vapor-liquid device for distillation, also known as a distillation tower. There are two main types of fractionation towers: plate towers and packed towers. According to the operation type, it can be divided into two types: continuous fractionation towers and intermittent fractionation towers. The design and manufacturing process of the plate tower is inseparable from the fixation of the tower plate, and the flatness and horizontality of the tower plate are crucial to the performance of the tower plate; and the specific form of the tower plate fixing structure also directly affects the production cycle of the plate tower.

[0003] After searching, a Chinese patent with publication number CN201394373Y discloses a tower plate fixing structure of a plate tower, which includes tower plates installed circumferentially on the inner wall of a tower body, a fixing ring is sealed and welded on the circumferential wall of the tower body, and a plurality of levers are equidistantly placed or arranged in the circumferential groove of the fixing ring. After the tower plate is placed on the fixing ring or the lever body, the lever is used to press the tower plate and fix it; the tower plate is placed on the flat upper surface of the fixing ring, and is pressed on the upper surface of the tower plate and fixedly connected with the lever; it has the characteristics of simple structure, easy use and installation, shortened manufacturing period, easy disassembly and assembly of the tower plate, and stable performance.

[0004] Although the above scheme can shorten the manufacturing period and facilitate the disassembly and assembly of the tower plates, the fixing structure in the above patent is difficult to use for tower plates of different specifications and can only fix one type of tower plate. Therefore, we provide a tower plate fixing structure for a plate tower to solve the above problems. Utility Model Content

[0016] 2. The utility model arranges a guide rod, a reset spring, a baffle rod, and a supporting ratchet, and supports the baffle rod through the reset spring, so that the baffle rod can always maintain contact with the teeth on the inner circumferential surface of the supporting ratchet. When the external force rod rotates in the forward direction, the inclined surface at one end of the baffle rod slides in contact with the teeth on the inner wall of the supporting ratchet. When the external force rod stops rotating, the baffle rod is located between the teeth on the inner wall of the supporting ratchet, which can prevent the external force rod from loosening due to reverse rotation.

An eccentric groove wheel 22 is fixedly arranged on one end of the external force-bearing rod 21, and a groove on one side of the eccentric groove wheel 22 is slidably connected to the outer circumferential surface of one end of a transmission rod 23, thereby further achieving the displacement of the transmission rod 23, and the other end of the transmission rod 23 is fixedly connected to the bottom side of a driven inner ring 24, thereby further achieving the rotation of the driven inner ring 24.

[0028] See also Figure 1 and Figure 3 The driven inner ring 24 and the fixed outer ring 28 are at the same axis, so that the support splint 26 fixes the tower plate body 4 more stably to prevent the tower plate body 4 from tilting. The fixed outer ring 28 is in a fixed state in the use scenario. One end of the blocking rod 14 is set as an inclined surface, so that when the blocking rod 14 follows the positive rotation of the external force rod 21, one end of the blocking rod 14 is in sliding contact with the teeth of the inner circumferential surface of the support ratchet 10. The top of the driven inner ring 24 is fixedly provided with a first support column 25, which plays a supporting and transmission role for the support splint 26. The outer circumference of the first support column 25 The circumferential surface is fixedly connected to one end of the support splint 26, and the outer surface of one end of the support splint 26 contacts the groove on the outer circumferential surface of the tower plate body 4, so as to facilitate stable support of the tower plate body 4.
