Description

Technical Field

[0001] This utility model relates to the field of tray technology, and in particular to composite tray structures. Background Technology

[0002] With the continuous development of modern industry, industries such as chemical, petroleum, and pharmaceutical have placed higher demands on the separation efficiency, processing capacity, and operational stability of tower equipment. Traditional tray structures, such as sieve tray towers and valve tray towers, have gradually revealed problems such as low mass transfer efficiency, low throughput, and narrow operational flexibility when handling some complex systems or high-difficulty separation tasks.

[0003] In current composite tray structures, the spacing between multiple packing layers and mesh plates cannot be adjusted. When the spacing cannot be adjusted, it is difficult to optimize the flow path of gas and liquid according to the actual situation, which can easily lead to gas flow deviation or liquid stagnation, preventing sufficient gas-liquid contact, reducing mass transfer efficiency, and causing liquid to accumulate locally, while gas will choose the channel with less resistance to pass through, resulting in uneven gas-liquid distribution. In addition, the packing in existing composite tray structures can become clogged after long-term use, and cannot be replaced individually, but only as a whole, which makes them impractical. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in existing technologies, the spacing between multiple packing layers and mesh plates cannot be adjusted. When the gap cannot be adjusted, it is difficult to optimize the flow path of gas and liquid according to the actual situation, which can easily lead to gas flow deviation or liquid stagnation, preventing sufficient gas-liquid contact, reducing mass transfer efficiency, causing liquid to easily accumulate locally, while gas will choose to pass through channels with less resistance, resulting in uneven gas-liquid distribution and blockage of the packing material after long-term use. The problem is that the packing material cannot be replaced individually and can only be replaced as a whole. Therefore, a composite tray structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a composite tower plate structure, including a mesh plate, with four support frames installed at the bottom of the mesh plate, and multiple connecting plates slidably placed inside the four support frames. The top of each connecting plate is fixed with packing material. The top of the mesh plate is provided with an installation / removal structure for installing and removing the support frames. A lifting plate is slidably connected between two support frames. Limiting plates are fixed on both sides of one end of the lifting plate. One end of the connecting plate is placed between the two limiting plates. A support plate is fixed to the outer wall of the lifting plate. The support plate is fixed to the support frame by a second bolt. Multiple limiting holes matching the second bolt are opened on the outer wall of the support frame.

[0006] Preferably, the installation and dismantling structure includes a plug fixed to the top of the support frame. The top of the plug penetrates the mesh plate and is located above the mesh plate. The top of the mesh plate is fixed to both sides of the plug. A pin is provided in both of the two fixed plates. The output end of the pin penetrates the two fixed plates and the plug and is threaded with a nut.

[0007] Preferably, both ends of the connecting plate are provided with a stop block, and a locking block is fixed to one end of each of the two stop blocks facing each other. The locking block is fixed to the connecting plate by a first bolt.

[0008] Preferably, a slider is installed at one end of the lifting plate by screws, and one end of one of the support frames is provided with a groove that matches the slider, and the slider slides in the groove.

[0009] Preferably, a mounting plate is fixed to the bottom end of the support frame, and the mounting plate has mounting holes.

[0010] Preferably, both ends of the connecting plate are provided with slots that match the card blocks, and the card blocks are inserted into the slots.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, two stops are installed at both ends of the connecting plate to limit its position, ensuring stable placement within the four support frames for installation. When the two stops are removed, one end of the connecting plate is no longer limited, allowing the user to directly move the connecting plate and the packing material fixed at its bottom for individual replacement, enhancing its practicality. Furthermore, the device features a lifting plate with limit plates fixed to both sides of one end. The connecting plate is placed within these limit plates. When the lifting plate moves up and down, it moves the connecting plate between the two limit plates, adjusting the gap between the packing material and between the packing material and the mesh plate. With the support plate, second bolt, and limiting holes, once the lifting plate is adjusted to the appropriate position, the height of the lifting plate can be determined by inserting the second bolt through the support plate and placing it within the corresponding limiting hole.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a composite tower plate structure, including a mesh plate 1. Four support frames 4 are installed at the bottom of the mesh plate 1. Multiple connecting plates 2 are slidably placed inside the four support frames 4. The top of the connecting plates 2 is fixed with packing 3. The top of the mesh plate 1 is provided with an installation and removal structure 5 for installing and removing the support frames 4. A lifting plate 10 is slidably connected between two support frames 4. Limiting plates 11 are fixed on both sides of one end of the lifting plate 10. One end of the connecting plate 2 is placed between the two limiting plates 11. A support plate 12 is fixed on the outer wall of the lifting plate 10. The support plate 12 is fixed to the support frame 4 by a second bolt 13. Multiple limiting holes 14 matching the second bolt 13 are opened on the outer wall of the support frame 4.

[0021] The overall effect of Embodiment 1 is that, through the setting of the mesh plate 1 and the packing 3, the gas rises through the openings on the mesh plate 1, and the liquid flows through the packing 3 under the action of gravity. The gas and liquid phases have sufficient contact and mass transfer on the surface and gaps of the mesh plate 1 and the packing 3. The mesh plate 1 can disperse the gas and support the packing 3, while increasing the gas-liquid contact area. The packing 3 further enhances the gas-liquid mass transfer process and improves the mass transfer efficiency. Through the setting of the lifting plate 10, and the fact that the limiting plates 11 are fixed on both sides of one end of the lifting plate 10, and the connecting plate 2 is placed in the limiting plate 11, when the lifting plate 10 is raised or lowered, it can drive the connecting plate 2 placed between the two limiting plates 11 to be raised or lowered, thereby adjusting the gap between the packing 3 and the packing 3 or between the packing 3 and the mesh plate 1. Through the setting of the support plate 12, the second bolt 13 and the limiting hole 14, after the lifting plate 10 is adjusted to a suitable position, the height of the lifting plate 10 can be positioned by simply passing the second bolt 13 through the support plate 12 and placing it in the corresponding limiting hole 14.

[0022] Example 2, as Figure 1-4 As shown, the installation and dismantling structure 5 includes a plug 501 fixed to the top of the support frame 4. The top of the plug 501 passes through the mesh plate 1 and is located above the mesh plate 1. Fixing plates 502 are fixed on both sides of the top of the mesh plate 1. A pin 503 is provided in both fixing plates 502. The output end of the pin 503 passes through the two fixing plates 502 and the plug 501 and is threadedly connected to a nut 504. Both ends of the connecting plate 2 are provided with a stop block 6. A locking block 7 is fixed at the opposite end of the two stop blocks 6. The locking block 7 is fixed to the connecting plate 2 by a first bolt 9. A slider 15 is installed at one end of the lifting plate 10 by a screw. One end of one of the support frames 4 is provided with a groove 16 that matches the slider 15. The slider 15 slides in the groove 16. An installation plate 17 is fixed at the bottom of the support frame 4. An installation hole 18 is provided in the installation plate 17. Both ends of the connecting plate 2 are provided with a slot 8 that matches the locking block 7. The locking block 7 is inserted into the slot 8.

[0023] The overall effect of Embodiment 2 is that, by installing two stops 6 at both ends of the connecting plate 2, the two ends of the connecting plate 2 can be limited, allowing it to be stably placed within the four support frames 4, thus achieving the installation effect. When the two stops 6 are removed, one end of the connecting plate 2 is no longer limited by the two stops 6, and the user can directly move the connecting plate 2 and the packing 3 fixed at its bottom end horizontally to replace the individual packing 3, making it more practical. This is achieved through the insertion block 501, fixing plate 502, pin 503, and... With the nut 504 in place, when the pin 503 passes through the fixing plate 502 and the insert block 501 and is threadedly connected to the nut 504, the mesh plate 1 and the insert block 501 are fixedly installed, thus allowing the four support frames 4 to be installed. When the nut 504 is unscrewed and the pin 503 is removed, the insert block 501 is no longer fixed to the support frame 4. At this time, the user can remove the mesh plate 1 separately and replace it, making it more practical. The mounting plate 17 and the mounting hole 18 facilitate the overall installation and disassembly of the device.

[0024] Working Principle: In use, the device allows gas to rise through openings in the mesh plate 1 and the packing 3, while liquid flows through the packing 3 under gravity. The gas and liquid phases fully contact and transfer mass on the surfaces and in the gaps of the mesh plate 1 and packing 3. The mesh plate 1 disperses the gas and supports the packing 3, increasing the gas-liquid contact area. The packing 3 further enhances the gas-liquid mass transfer process and improves mass transfer efficiency. Two baffles 6 are installed at both ends of the connecting plate 2, limiting its position and ensuring stable placement within the four support frames 4. When the baffles 6 are removed, one end of the connecting plate 2 is no longer limited, allowing the user to move it horizontally. The connecting plate 2 and the packing 3 fixed at its bottom end allow for individual replacement of each packing 3, making it more practical. In addition, the device is equipped with a lifting plate 10, with limit plates 11 fixed on both sides of one end of the lifting plate 10. The connecting plate 2 is placed inside the limit plates 11. When the lifting plate 10 is raised or lowered, it can drive the connecting plate 2 placed between the two limit plates 11 to be raised or lowered, thereby adjusting the gap between the packing 3 and the packing 3 or between the packing 3 and the mesh plate 1. With the support plate 12, the second bolt 13 and the limiting hole 14, after the lifting plate 10 is adjusted to a suitable position, the height of the lifting plate 10 can be positioned by simply passing the second bolt 13 through the support plate 12 and placing it in the corresponding limiting hole 14.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
