Description

Technical Field

[0001] This utility model relates to the field of packing ring technology, and in particular to a tie rod type packing ring. Background Technology

[0002] In the field of chemical production, chemical towers are core equipment for realizing mass transfer, heat transfer and other processes. The stability of the packing inside the tower directly affects the operating efficiency and production quality of the entire tower. As a key mass transfer element in chemical towers, the packing needs to be fixed by specific internal components to prevent it from loosening, shifting or even being blown over by the impact of rising gas below. The packing pressure ring is an important internal component that undertakes this pressing and fixing function. It is widely used in chemical tower equipment such as pressure reducing towers and is a key component to ensure the stable operation of the tower.

[0003] Traditional packing pressure rings mostly adopt a grid-like integral structure with horizontal and vertical ribs arranged in an alternating manner. The horizontal and vertical ribs are connected to form a complete frame by welding or bolting. The technical principle is to use the structural rigidity and weight of the integral frame to form uniform and continuous pressure on the packing below. Through this integral pressing method, the impact force generated when the gas rises is resisted, thereby stabilizing and confining the packing within a preset area.

[0004] However, with traditional packing rings using this grid-type integral structure, when the packing in a local area of ​​the tower needs to be repaired or replaced due to wear, aging, or other reasons, the horizontal and vertical ribs are interconnected to form an inseparable integral frame. Therefore, a large area of ​​the entire packing ring structure must be dismantled before the packing to be repaired can be accessed. This not only significantly increases the workload of disassembly and installation during the repair process but also prolongs the repair time, adversely affecting the continuous production of the chemical tower. To address this issue, a tie-rod type packing ring is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tie-rod type packing pressure ring, which aims to improve the problem of large-area removal of the pressure ring and large workload required when repairing and replacing local packing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tie-rod type packing ring includes a chemical tower body and multiple parallel packing bars, each of which is composed of multiple longitudinally arranged round steel bars. Each packing bar is slidably connected inside the chemical tower body, and each packing bar has a connecting component at both ends.

[0008] Moreover, each of the connecting components includes a connecting plate one and a connecting plate two. One side of each connecting plate one is fixedly connected to one end of the pressure strip one and the pressure strip two, and one side of each connecting plate two is fixedly connected to the inner wall of the chemical tower body.

[0009] Furthermore, each of the connecting plates has symmetrical bolt holes and a bolt threaded into it. Adjacent pressure strips 1 and 2 are connected end to end through the connecting plates and bolts.

[0010] Furthermore, each of the connecting plates has an elongated hole inside, and each of the pressure strips is fixedly connected to a connecting plate, which also has an elongated hole inside.

[0011] Furthermore, each of the three connecting plates is attached to one side of the second connecting plate, and each of the three connecting plates and the second connecting plate has a bolt inserted inside.

[0012] Furthermore, the bolt two passes through the elongated hole to fix the connecting plate two and the connecting plate three, and the pressure strip one and the pressure strip two are arranged in parallel at intervals to form a whole for pressing the filler.

[0013] This utility model has the following beneficial effects:

[0014] In this utility model, a flexible connection structure is formed by connecting plate one, bolt one, connecting plate two, connecting plate three, and bolt two. When local packing needs to be repaired, disassembly and repair can be completed by simply removing the connecting bolts of the corresponding pressure strip, thereby achieving the effect of convenient packing repair. This provides convenient operation for maintenance personnel, solves the problem that traditional pressure rings need to be completely removed for local repair, greatly reduces the amount of maintenance work, and improves the efficiency of packing repair and maintenance.

[0023] 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.

[0024] Reference Figure 1 - Figure 6 This utility model provides an embodiment of a tie-rod type packing pressure ring, including a chemical tower body 1, multiple parallel pressure strips 2 and 3. Each pressure strip 2 and 3 is composed of multiple longitudinally arranged round steel bars. These round steel bars are distributed in an orderly manner along the axial direction of the chemical tower and jointly undertake the function of pressing the packing inside the tower. Each pressure strip 2 and 3 is slidably connected inside the chemical tower body 1. Each pressure strip 2 and 3 has connecting components at both ends for splicing the pressure strip itself and connecting it to the chemical tower body 1. Each connecting component includes a connecting plate 4 and a connecting plate 7. One side of each connecting plate 4 is fixedly connected to one end of the pressure strip 2 and the pressure strip 3. One side of the connecting plate 4 is connected by welding and fixed to the end of the pressure strip 2 and the pressure strip 3. The other side of the connecting plate 7 is also fixed to the inner wall of the chemical tower body 1 by welding, serving as a support base for connecting the pressure strip to the tower body.

[0025] Each connecting plate 27 is fixedly connected to the inner wall of the chemical tower body 1 on one side. Each connecting plate 14 has symmetrical bolt holes 5 inside. Each connecting plate 14 has a threaded bolt 6 inside. When it is necessary to splice adjacent pressure strips 12 and 23, the ends of adjacent pressure strips can be precisely connected by using the connecting plate 14 and the bolt 16 to achieve end-to-end connection, so that multiple pressure strips form a continuous pressing structure, ensuring the overall pressing effect on the packing.

[0026] Adjacent pressure strips 1 and 2 are connected end to end by connecting plate 1 and bolt 16. Each connecting plate 2 has an elongated hole 10 inside. The elongated hole 10 has a certain length, which can provide a certain amount of movement for the connecting bolt when the pressure strip slides to adjust its position. The other end of each pressure strip 1 and 2 is fixedly connected to a connecting plate 3. The connecting plate 3 and the connecting plate 2 cooperate to fix the pressure strip to the tower body.

[0027] Each connecting plate 3 (8) and connecting plate 2 (7) has an elongated hole 10 inside. One side of each connecting plate 3 (8) fits against the connecting plate 2 (7). After they are fitted together, bolt 2 (9) passes through the elongated hole 10 to fix the connecting plate 2 (7) and connecting plate 3 (8). The cooperation between the elongated hole 10 and bolt 2 (9) restricts the displacement of the pressure strip in the non-sliding direction, ensuring connection stability, while also allowing bolt 2 (9) to move slightly within the elongated hole 10 during sliding adjustments of the pressure strip, adapting to changes in the pressure strip's position. Each connecting plate 3 (8) and connecting plate 2 (7)... Bolts 2 and 9 are inserted inside each of the two plates 7. Bolts 2 and 9 pass through the elongated holes 10 to fix the two plates 7 and 8. The pressure strips 1 and 2 are arranged in parallel and spaced apart. Multiple pressure strips cooperate with each other to form a mesh pressing structure covering the corresponding packing area in the chemical tower. Pressure is applied to the packing from multiple directions, thereby forming an integral structure for pressing the packing. This effectively prevents the packing from being blown over by the rising gas below, ensuring the stable operation of mass transfer, heat transfer and other processes in the chemical tower, and forming an integral structure for pressing the packing.

[0028] Working principle: When using this tie-rod type packing pressure ring, firstly, multiple pressure strips 2 and 3 are arranged in parallel. Then, bolts 6 are inserted into bolt holes 5 inside connecting plate 4 to form an integral pressing structure. At the same time, connecting plate 8 at one end of pressure strips 2 and 3 is aligned with connecting plate 7 on the inner wall of the chemical tower body 1. Bolts 9 are inserted into the elongated hole 10 and then tightened to fit and install, so that pressure strips 2 and 3 can be firmly connected to the chemical tower body 1. In this way, the pressure ring can effectively compress the packing inside the packing tower, resist gas impact, and ensure the stability of the packing. When local packing needs maintenance, the corresponding pressure strip can be removed by rotating the corresponding bolt, solving the problem of traditional pressure ring maintenance requiring overall removal and achieving efficient operation.
