Description

Technical Field

[0001] This utility model relates to the technical field of sieve tray tower accessories, and in particular to a sieve tray tower that is easy to install. Background Technology

[0002] Sieve trays are a classic gas-liquid mass transfer device, widely used in chemical unit operations such as distillation and absorption. Their structure mainly consists of trays with numerous sieve openings. Liquid flows down from the upper tray through downcomers, forming a liquid layer on the tray, while gas flows upward through the sieve openings, achieving full contact with the liquid to realize mass and heat transfer. Sieve trays have advantages such as simple structure, low cost, moderate pressure drop, and ease of maintenance, making them suitable for the separation of clean systems or low-viscosity liquids.

[0003] Existing sieve trays are typically composed of multiple trays joined together, with adjacent trays connected by ribs having several connection holes. Bolts are inserted into these holes for assembly, but the large number of bolts makes tray assembly slow and inconvenient. Secondly, the trays themselves are fixed to the inner wall of the tower with bolts. Each time the trays need cleaning, the bolts must be removed and the trays disassembled, then cleaned and reinstalled. This installation method is inefficient and requires further improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-install sieve tray tower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sieve tray for easy installation, comprising two semicircular discs and two mounting plates. Each of the two semicircular discs has several circular holes, and each of the two semicircular discs has a rib plate fixed on its adjacent lower surface. The surfaces of the two rib plates are jointly fixed with a connecting component. Each of the two semicircular discs has a notch on its opposite side. The upper surface of each semicircular disc and near the notch is fixed with a mounting component. The two mounting plates pass through the notches of the two semicircular discs respectively, and the surfaces of the mounting plates are fixed with clips for engaging the mounting components.

[0006] Furthermore, each of the two prism plates is provided with a plurality of connecting holes. The docking assembly includes a U-shaped plate located on the surface of the two prism plates. A screw is rotatably connected to the side wall of the U-shaped plate through a thread. A movable plate is rotatably connected to the side of the screw near the prism plate through a bearing. A plurality of insert rods are fixed to the side of the movable plate away from the screw. The plurality of insert rods are respectively inserted into the plurality of connecting holes. A handle is fixed to the other end of the screw.

[0007] Furthermore, a guide rod is fixed to the side of the movable plate near the screw, and the guide rod passes through the U-shaped plate and is slidably connected to the U-shaped plate.

[0008] Furthermore, the mounting plate has mounting holes, and bolts are connected inside the mounting holes.

[0009] Furthermore, the mounting assembly includes a vertical plate fixed to the upper surface of the semi-circular disk, and a through hole is provided in the middle of the vertical plate. A locking rod is slidably connected inside the through hole. The end of the locking rod near the mounting plate is inserted into the inside of the retaining sleeve. An end plate is fixed to the end of the locking rod away from the retaining sleeve. A tension spring is fixedly connected between the end plate and the vertical plate.

[0010] Furthermore, a pull ring is fixed to the side of the end plate away from the lever.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a sieve tray for easy installation is disclosed, comprising two semi-circular discs 1 and two mounting plates 7. Each of the two semi-circular discs 1 has several circular holes 2, and each of the two semi-circular discs 1 has a rib plate 3 fixed on the lower surface of the adjacent side. The surfaces of the two rib plates 3 are jointly fixed with a connecting component 4. Each of the two semi-circular discs 1 has a notch 5 on the side away from each other. The upper surface of the semi-circular discs 1 and near the notch 5 are fixed with a mounting component 6. The two mounting plates 7 pass through the notches 5 of the two semi-circular discs 1 respectively, and the surfaces of the mounting plates 7 are fixed with a retainer 71 for engaging the mounting component 6.

[0023] Both prism plates 3 are provided with several connecting holes 31. The docking assembly 4 includes a U-shaped plate 41 located on the surface of the two prism plates 3. The side wall of the U-shaped plate 41 is penetrated and connected to a screw 42 by a thread. The side of the screw 42 near the prism plate 3 is connected to a movable plate 43 by a bearing. Several insert rods 44 are fixed on the side of the movable plate 43 away from the screw 42. The insert rods 44 are respectively inserted into the several connecting holes 31. The other end of the screw 42 is fixed with a handle 45.

[0024] In this embodiment, the number of connecting holes 31 on each prism plate 3 is the same as the number of insert rods 44. When splicing two semi-circular disks 1 by prism plates 3, the prism plates 3 of the two semi-circular disks 1 are first attached and spliced ​​together, then the U-shaped plate 41 is clamped on the surface of the two prism plates 3, and then the handle 45 on the screw 42 is rotated to drive the screw 42 and the moving plate 43 to move to one side of the prism plate 3, so that multiple insert rods 44 are inserted into multiple connecting holes 31 respectively, thereby realizing the compression, positioning and fixing of the two prism plates 3.

[0025] A guide rod 46 is fixed on the side of the movable plate 43 near the screw 42. The guide rod 46 passes through the U-shaped plate 41 and is slidably connected to the U-shaped plate 41.

[0026] Since the screw 42 needs to rotate, the guide rod 46 guides the moving plate 43 to prevent the moving plate 43 from rotating with the screw 42.

[0027] The mounting plate 7 has mounting holes 72, and bolts are connected inside the mounting holes 72.

[0028] When fixing the mounting plate 7, screw the bolts that pass through the mounting hole 72 into the holes inside the tower body to fix the mounting plate 7.

[0029] Mounting assembly 6 includes a vertical plate 61 fixed to the upper surface of the semi-circular disk 1, and a through hole 62 is provided in the middle of the vertical plate 61. A locking rod 63 is slidably connected inside the through hole 62. The end of the locking rod 63 near the mounting plate 7 is inserted into the sleeve 71. An end plate 64 is fixed to the end of the locking rod 63 away from the sleeve 71. A tension spring 65 is fixedly connected between the end plate 64 and the vertical plate 61.

[0030] After the mounting plate 7 is fixed, install the assembled semi-circular disk 1. First, pull the end plate 64 to move it away from the mounting plate 7. Then, move the semi-circular disk 1 downwards so that the retaining sleeve 71 passes through the notch 5. When the retaining rod 63 is aligned with the retaining sleeve 71, release the end plate 64. The tension spring 65 will pull the end plate 64 back to its original position, causing the retaining rod 63 to engage inside the retaining sleeve 71, thus fixing the semi-circular disk 1. When it is necessary to disassemble the semi-circular disk 1, simply pull the end plate 64 to separate the retaining rod 63 from the retaining sleeve 71.

[0031] A pull ring is fixed to the side of the end plate 64 away from the latch 63. The pull ring makes it easier to pull the end plate 64.

[0032] Working principle: During installation, the two mounting plates 7 are first symmetrically fixed inside the tower body with bolts. Then, the two semi-circular disks 1 are spliced ​​on the outside of the tower body. The splicing method is to use the mating assembly 4 to clamp the bottom edge plates 3 of the two semi-circular disks 1, thus completing the splicing of the two semi-circular disks 1. After the splicing is completed, the two semi-circular disks 1 are placed inside the tower body, and then the clamping rod 63 of the mounting assembly 6 engages with the clamping sleeve 71 on the mounting plate 7 to achieve quick installation of the two semi-circular disks 1. When disassembling the semi-circular disks 1, simply pull the end plate 64; it is not necessary to disassemble the mounting plate 7.

[0033] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
