Description

Technical Field

[0001] This utility model relates to the field of distillation column technology, and more specifically, to a low-temperature distillation column. Background Technology

[0002] Low-temperature distillation columns utilize the different boiling points of components in a mixture, partially liquefying the gas through cooling and then separating it through distillation. An existing two-stage distillation column for low-temperature heat pump distillation, disclosed in CN213790037U, includes a tank. The top of the tank is connected to a discharge pipe, and the bottom is connected to a first drain pipe. A skirt is fixedly installed externally on the tank. A first grid plate is fixedly installed internally. A first packing is fixedly installed internally on top of the first grid plate. A second grid plate is fixedly installed internally above the first packing, and a second packing is fixedly installed internally on top of the second grid plate. A baffle ring is fixedly installed internally below the second grid plate. This aforementioned two-stage distillation column for low-temperature heat pump distillation has a stable and reasonable structure, enabling single-stage and two-stage distillation of mixed gases. It effectively saves on equipment purchase costs and gas pipeline costs, and improves gas separation efficiency.

[0003] However, in the above solution, since the distillation column has a certain height, when cleaning its exterior, the staff need to use tools to climb it, which consumes the staff's physical strength. In addition, the staff need to frequently change climbing locations, which is very time-consuming and reduces cleaning efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide a low-temperature distillation column that can effectively solve the problem in the prior art where distillation columns have a certain height, requiring workers to use tools to climb and expend physical strength when cleaning their exteriors. Furthermore, workers need to frequently change climbing locations, which is very time-consuming and reduces cleaning efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A low-temperature distillation column includes a column body, a support ring fixedly fitted on the outer wall of the column body, and a plurality of support legs fixedly installed on the lower surface of the support ring.

[0007] Uprights are fixedly installed on both sides of the upper surface of the support ring. A lifting seat is slidably mounted on the two uprights. Two limit rods are fixedly installed on the lifting seat. A drive assembly for driving the lifting seat to move is provided at the upper end of the two uprights.

[0008] Preferably, the drive assembly includes a gantry frame, which is fixedly installed on the upper ends of two uprights, and a dual-axis motor is fixedly installed on the top of the gantry frame via a mounting bracket;

[0009] The gantry frame is rotatably mounted on one side away from each other. The opposite ends of the two rotating rods pass through the gantry frame and are fixedly connected to the output shaft of the dual-axis motor. The shafts of the two rotating rods are fitted with winches, and steel wire ropes are wound around the winches.

[0010] Preferably, a limit ring is fixedly installed at one end of each of the two wire ropes, and the two limit rings are respectively sleeved on the corresponding limit rod body.

[0011] Preferably, protective sleeves are fixedly installed on both sides of the bottom of the lifting seat, and the two protective sleeves are respectively fitted onto the outside of the corresponding uprights.

[0012] Preferably, the upper surface of the gantry frame is provided with a protective structure for protection.

[0013] Preferably, the protective structure includes a cylinder, which is fixedly mounted on the upper surface of the gantry, and the cylinder output end passes through the gantry and is fixedly mounted with a limit bracket.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The staff enters the lifting seat through the gap in the lifting seat. Then the staff starts the dual-shaft motor, which drives the rotating rod to rotate. Under the rotation of the winch, the wire rope is continuously wound around the winch body, so that one end of the wire rope pulls the limit ring, which in turn pulls the limit rod, thereby raising the lifting seat. This makes it convenient for the staff to clean the outer wall of the tower. The staff does not need to climb, and there is no need to frequently change the climbing position, which reduces the physical exertion of the staff and improves the cleaning efficiency.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1-4 As shown, a low-temperature distillation column includes a column body 1, a support ring 2 fixedly fitted on the outer wall of the column body 1, and a plurality of support legs 3 fixedly installed on the lower surface of the support ring 2.

[0023] Uprights 4 are fixedly installed on both sides of the upper surface of the support ring 2. The lifting seat 5 is slidably mounted on the two uprights 4. Two limit rods 6 are fixedly installed on the body of the lifting seat 5. The upper end of the two uprights 4 is provided with a drive assembly 7 for driving the lifting seat 5 to move.

[0024] The drive assembly 7 includes a gantry frame 701, which is fixedly installed on the upper ends of two uprights 4. A dual-axis motor 703 is fixedly installed inside the top of the gantry frame 701 via a mounting bracket 702.

[0025] The gantry frame 701 has rotating rods 704 mounted on opposite sides. The opposite ends of the two rotating rods 704 pass through the gantry frame 701 and are fixedly connected to the output shaft of the dual-axis motor 703. The shafts of the two rotating rods 704 are fitted with winches 7041, and steel wire ropes 705 are wound around the winches 7041.

[0026] Each of the two steel wire ropes 705 has a limit ring 706 fixedly installed at one end, and the two limit rings 706 are respectively sleeved on the corresponding limit rod 6.

[0027] In another embodiment of this utility model, protective sleeves 8 are fixedly installed on both sides of the bottom of the lifting seat 5, and the two protective sleeves 8 are respectively fitted onto the outside of the corresponding uprights 4.

[0028] Workers enter the lifting platform 5 through the opening in the lifting platform 5. Then, the workers start the dual-shaft motor 703, which drives the rotating rod 704 to rotate. Under the rotation of the winch 7041, the wire rope 705 continuously winds around the winch 7041, causing one end of the wire rope 705 to pull the limiting ring 706, which in turn pulls the limiting rod 6, thereby raising the lifting platform 5. This makes it easier for workers to clean the outer wall of the tower 1 without having to climb or frequently change climbing positions, reducing the physical exertion of workers and improving cleaning efficiency.

[0029] In another embodiment of this utility model, a protective structure 9 for protection is provided on the upper surface of the gantry frame 701.

[0030] The protective structure 9 includes a cylinder 901, which is fixedly installed on the upper surface of the gantry 701. The output end of the cylinder 901 passes through the gantry 701 and is fixedly installed with a limit bracket 902.

[0031] After the lifting seat 5 stops moving, the cylinder 901 is activated, causing its output end to drive the limit frame 902 to move, so that the limit frame 902 presses against the rotating rod 704 to prevent it from rotating, thereby improving the protection effect and effectively ensuring the personal safety of the staff.

[0032] The working principle of this type of low-temperature distillation column:

[0033] In use, workers enter the lifting platform 5 through the notch in the lifting platform 5. Then, the workers start the dual-shaft motor 703, which drives the rotating rod 704 to rotate. Under the rotation of the winch 7041, the wire rope 705 is continuously wound around the winch 7041, causing one end of the wire rope 705 to pull the limiting ring 706, which in turn pulls the limiting rod 6, thereby raising the lifting platform 5. This makes it easier for workers to clean the outer wall of the tower 1 without having to climb or frequently change climbing positions, reducing the physical exertion of workers and improving cleaning efficiency.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
