Description

Technical Field

[0001] This utility model relates to the field of plate towers in chemical production equipment, and in particular to a plate tower plate with a convenient disassembly device. Background Technology

[0002] In the field of chemical production, plate towers are widely used in operation units such as distillation, absorption, extraction, washing, and heat transfer. The structure and performance of plate towers, especially the structure and performance of the tower plates, not only have a decisive impact on production load and product quality, but are also important factors in determining the basic investment and operating costs of the equipment.

[0003] Traditional plate towers mostly use bolts or welding to fix the tower plates, which requires point-by-point operation during disassembly and assembly, which is time-consuming, labor-intensive, and prone to damaging the tower body. The support structure relies on single-sided locking or rigid connection, and the manually adjusted mechanical limit device lacks automated drive and trajectory control. The disassembly and assembly process is cumbersome and prone to jamming, making it difficult to meet the frequent maintenance needs under high load conditions, further increasing maintenance costs and downtime risks. To address these issues, a plate tower with a convenient disassembly device is provided. Utility Model Content

The embodiments of this utility model will be described below based on its overall structure.

[0026] Reference Figures 1 to 5 In this embodiment of the utility model, a plate tower plate with a convenient disassembly device includes:

[0027] Plate tower body 1;

[0028] The sieving tray mechanism 2 is installed inside the plate tower body 1. The sieving tray mechanism 2 is used to make the gas pass through the holes and have uniform and efficient contact with the liquid.

[0029] The rapid loading and unloading mechanism 3 is set at the bottom of the screening tray mechanism 2. The rapid loading and unloading mechanism 3 is used to quickly fix or disassemble the screening tray mechanism 2 inside the plate tower body 1.

[0030] The screening tray mechanism 2 includes a main body 21. Several sets of sieve holes 22 are evenly opened on the upper part of the main body 21. An inlet overflow weir 24 and an outlet overflow weir 25 are fixedly connected above the sieve holes 22. A liquid receiving platform 23 is provided between the inlet overflow weir 24 and the inner wall of the tray tower body 1. A downcomer 26 is opened on the upper part of the main body 21 at the position between the outlet overflow weir 25 and the inner wall of the tray tower body 1.

[0031] Using the above scheme: the main body 21 disperses the rising gas into a fine stream through the sieve holes 22 and passes through the liquid layer. The inlet overflow weir 24 controls the initial distribution of the liquid entering the main body 21. The outlet overflow weir 25 maintains the liquid layer height on the plate. The liquid flows from the upper layer into the receiving platform 23 through the downcomer 26 to eliminate the impact force. Then, it passes through the sieve hole 22 area and comes into countercurrent contact with the gas to complete the mass transfer. Finally, the liquid crosses the outlet overflow weir 25 and enters the downcomer 26 to flow to the next layer.

[0032] The tray quick loading and unloading mechanism 3 includes an upper fixed arc plate 31, which is fixedly connected to the lower part of the main body 21. Five sets of arc-shaped sliding grooves 32 are equidistantly arranged in an annular pattern below the upper fixed arc plate 31. A fixed rod 33 is fixedly connected to the lower part of the main body 21. An electric telescopic rod 34 is rotatably connected to the outer side of the fixed rod 33. A lower rotating arc plate 35 is rotatably connected to the lower part of the upper fixed arc plate 31. Five sets of straight sliding grooves 36 are equidistantly arranged in an annular pattern on the inner side of the lower rotating arc plate 35. A support spring 37 is fixedly connected to the inner wall of the straight sliding groove 36. Four sets of first sliding plates 38 and one set of second sliding plates 311 are arranged below the lower rotating arc plate 35. An inner support plate 310 is fixedly connected to the outer side of the first sliding plate 38. The second sliding plate 311 and the four sets of first sliding plates 38 are fixedly connected to the outer side of the second sliding plate 311. Each sliding plate 38 is fixedly connected to a guide slide post 39. Each set of guide slide posts 39 slides through the straight sliding groove 36 to the inner side of the arc-shaped sliding groove 32. The two ends of each set of support springs 37 are fixedly connected to the inner side wall of the straight sliding groove 36 and the outer side of the guide slide post 39 at the corresponding positions, respectively. Each set of straight sliding grooves 36 below the lower rotating arc plate 35 has symmetrically opened grooves parallel to it on both sides. The first sliding plate 38 and the inner support plate 310 are fixedly connected to a slider that matches the groove, so that the first sliding plate 38 and the inner support plate 310 can slide back and forth along the direction of the straight sliding groove 36. The second sliding plate 311 is fixedly connected to a rotating seat 312 on its side. The two sides of the electric telescopic rod 34 are rotatably connected to the outer side of the rotating seat 312 and the fixed rod 33, respectively.

[0033] Using the above scheme: During disassembly, the electric telescopic rod 34 retracts and pulls the second sliding plate 311 towards the center, causing the rotating seat 312 to rotate, so that the four sets of first sliding plates 38 slide outward along the straight sliding groove 36, and the inner support plate 310 moves outward simultaneously and disengages from the support position of the inner wall of the plate tower body 1. At this time, the guide slide column 39 slides in the arc-shaped slide groove 32, and the support spring 37 is compressed and stores energy. When all the inner support plates 310 are completely disengaged, the entire screening tower plate mechanism 2 can be vertically moved down and removed. During installation, the operation is reversed. The electric telescopic rod 34 extends and pushes the second sliding plate 311 to reset. The support spring 37 releases its elastic force to make the guide slide column 39 reset and slide along the arc-shaped slide groove 32, causing the first sliding plate 38 and the inner support plate 310 to tighten inward and lock the inner wall of the plate tower body 1.

[0034] The working principle of this utility model is as follows: In the initial state, the inner support plate 310 of the tower plate quick loading and unloading mechanism 3 is in a retracted state, and the screening tower plate mechanism 2 is vertically hoisted to the preset height inside the tower body 1 of the plate tower.

[0035] When the electric telescopic rod 34 is activated, it extends and pushes the second sliding plate 311 to move away from the fixed rod 33, causing the rotating seat 312 to rotate. The movement of the second sliding plate 311 is driven by the sliding of the guide slide column 39 in the straight sliding groove 36, which drives the four sets of first sliding plates 38 to slide synchronously along the straight sliding groove 36 towards the inner wall of the plate tower body 1. The inner support plate 310 expands outward accordingly. During the sliding process, the guide slide column 39 slides along the arc-shaped sliding groove 32 of the upper fixed arc plate 31, and the support spring 37 is stretched to the initial state to ensure the stability of the sliding trajectory. When the inner support plate 310 is completely pressed against the inner wall of the plate tower body 1, the electric telescopic rod 34 stops moving. The inner support plate 310 is mechanically locked by the cooperation of the slider and the sliding grooves on both sides of the straight sliding groove 36, thus completing the fixation of the screening tower plate mechanism 2.

[0036] When the screening tray mechanism 2 needs to be disassembled, the electric telescopic rod 34 is activated to retract, pulling the second sliding plate 311 to move closer to the fixed rod 33. The rotating seat 312 rotates in the opposite direction. The movement of the second sliding plate 311 drives the four sets of first sliding plates 38 to slide outward along the straight sliding groove 36 through the guide slide column 39. The inner support plate 310 moves outward synchronously and disengages from the inner wall of the plate tower body 1. During the sliding process, the support spring 37 is compressed and stores energy. The guide slide column 39 slides along the arc-shaped slide groove 32 to ensure that the inner support plate 310 smoothly exits the locking position. When all the inner support plates 310 are completely disengaged from the inner wall of the plate tower body 1, the entire screening tray mechanism 2 is released from radial constraints and can be moved vertically downward to be removed from the plate tower body 1.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
