[0002] Adsorption separation experiments are processes that achieve separation by selectively adsorbing specific components in a mixture using an adsorbent, and by using an adsorbent material to absorb impurities carried inside the passing gas stream.

[0003] For example, patent application number 202010726237.3 published on the China Patent Network, entitled "An Apparatus and Method for Batch Adsorption Separation Experiments," includes: a cylinder, a sieve, a base, and a base support. The bases are connected to the base support, and the cylinder is fixed to the base via a fixing device. The sieve has a sieve frame around its perimeter, and the sieve frame has a gasket groove for placing gaskets. The sieve is connected to the cylinder and base via the sieve frame and sealed with a sealing ring. A discharge port is provided in the middle of the base.

The device is also low in cost, can be used multiple times, and has significant practical application value.

[0004] However, the existing screen installation method is relatively simple. The screen set inside the cylinder needs to be completely opened and removed, and it can only be operated from top to bottom, which is time-consuming and laborious, and affects the replacement efficiency of the bottom screen. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the cumbersome sieve plate replacement method in the existing technology, and to propose an adsorption separation test device.

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

[0007] An adsorption separation test device includes a base, on both sides of the top of the base, a frame is fixedly connected to the inner side of the frame, a support is fixedly connected to the side of the support away from the frame, a cylinder is fixedly connected to the inner side of the cylinder, a sieve plate is inserted into the cylinder, the sieve plate is slidably connected to the cylinder, and a positioning structure is provided on the top of the frame, the positioning structure can position the inserted sieve plate.

[0008] As a preferred technical solution of this application, the positioning structure includes a connecting plate fixedly connected to the outside of the frame. Both sides of the top of the connecting plate are movably connected to a swing rod via pins. The side of the swing rod away from the connecting plate is movably connected to a pressing rod via a bearing. The pressing rod is located on the outside of the cylinder and can clamp and position the screen plate by swinging the swing rod.

[0009] As a preferred technical solution of this application, a toothed ring is fixedly connected to the outer surface of the sieve plate, and a toothed column is fixedly connected to the outer surface of the extrusion rod. The toothed column is located outside the toothed ring and meshes with the toothed ring.

[0010] As a preferred technical solution of this application, a connecting frame is fixedly connected to the top of the cylinder body, and a bidirectional screw is movably connected to the inside of the connecting frame through a bearing. The left end of the bidirectional screw passes through to the left side of the connecting frame and is fixedly connected to a rotating wheel. Both sides of the surface of the bidirectional screw are threadedly connected to a screw sleeve, and both sides of the bottom of the screw sleeve are fixedly connected to a sliding rod located inside the swing rod. The sliding rod is slidably connected to the swing rod.

[0011] As a preferred technical solution of this application, a drive motor is fixedly connected to the top of one of the swing arms, and the output end of the drive motor passes through the swing arm and is fixedly connected to the top of the compression rod.

[0012] As a preferred technical solution of this application, the top of the connecting frame is set to be hollow, and the top of the screw sleeve is fixedly connected to a limiting block located inside the connecting frame, and the limiting block and the connecting frame are slidably connected.

[0013] Compared with the prior art, this utility model provides an adsorption separation test device, which has the following features:

[0014] Beneficial effects:

[0015] 1. This adsorption separation test device uses a frame and bracket to fix the cylinder body, forming a stable support and avoiding deformation caused by uneven stress on the sieve plate. At the same time, the positioning structure is directly integrated into the top of the frame, which can fix the inserted sieve plate without additional tools, simplifying the operation process. Moreover, the sieve plate is slidably connected to the cylinder body, and the insertion and removal path is clear, reducing the difficulty of alignment during replacement and improving replacement efficiency.

[0016] 2. This adsorption separation test device uses a swing arm to swing around a pin shaft, which drives the extrusion rod to move laterally to adapt to the clamping requirements of sieve plates of different sizes. The extrusion rod is connected by a bearing to ensure that the clamping force is evenly distributed along the outer surface of the sieve plate, avoiding local stress concentration that could damage the sieve plate.

[0017] 3. The adsorption separation test device uses a mechanical interlock formed by the meshing of the toothed ring and the toothed column to prevent the sieve plate from axially displacing under vibration or pressure. The meshing structure restricts the rotational freedom of the sieve plate, ensuring that the sieve plate maintains a fixed angle during the test.

[0018] 4. This adsorption separation test device drives the two screw sleeves on both sides to move synchronously in opposite directions through the rotation of the bidirectional screw, and pushes the pendulum to swing symmetrically through the slide bar to ensure symmetrical balance of the clamping force.

[0019] 5. This adsorption separation test device uses a drive motor to drive the toothed column to rotate and mesh with the toothed ring, eliminating the need for manual rotation of the squeezing rod, reducing operational intensity. Moreover, the drive motor can precisely control the rotation angle of the toothed column to ensure consistent meshing depth and improve locking reliability.

[0020] 6. This adsorption separation test device restricts the screw sleeve to move only along the screw axis by limiting the limiting block, which avoids the screw sleeve from deflecting due to the rotational inertia of the screw. The hollow design reduces the weight of the connecting frame, while retaining the sliding track of the limiting block, thus balancing lightweight and structural strength. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Reference Figure 1-4An adsorption separation test device includes a base 1. The base 1 has a frame 2 fixedly connected to both sides of its top. A support 3 is fixedly connected to the inner side of the frame 2. A cylinder 4 is fixedly connected to the side of the support 3 away from the frame 2. A sieve plate 5 is inserted into the inner side of the cylinder 4, and the sieve plate 5 is slidably connected to the cylinder 4. A positioning structure 6 is provided on the top of the frame 2. The positioning structure 6 can position the inserted sieve plate 5. The cylinder 4 is fixed by the frame 2 and the support 3, forming a stable support and preventing deformation caused by uneven force on the sieve plate 5. Simultaneously, the positioning structure 6 is directly integrated into the top of the frame 2, allowing for the fixing of the inserted sieve plate 5 without additional tools, simplifying the operation process. Furthermore, the slidable connection between the sieve plate 5 and the cylinder 4 provides a clear insertion and removal path, reducing alignment difficulty during replacement and improving replacement efficiency. The positioning structure 6 includes a connecting plate 7 fixedly connected to the outer side of the frame 2. A swing rod 8 is movably connected to both sides of the top of the connecting plate 7 via pins. A pressing rod 9 is movably connected to the side of the swing rod 8 away from the connecting plate 7 via a bearing. Located outside the cylinder body 4, the sieve plate 5 is clamped and positioned by a swinging rod 8. A toothed ring 10 is fixedly connected to the outer surface of the sieve plate 5. A toothed column 11 is fixedly connected to the outer surface of the extrusion rod 9. The toothed column 11 is located outside the toothed ring 10 and meshes with the toothed ring 10. A connecting frame 12 is fixedly connected to the top of the cylinder body 4. A bidirectional screw 13 is movably connected to the inside of the connecting frame 12 through a bearing. The left end of the bidirectional screw 13 extends through to the left side of the connecting frame 12 and is fixedly connected to a rotating wheel 14. Both sides of the surface are threaded with threaded sleeves 15. Both sides of the bottom of the threaded sleeves 15 are fixedly connected with slide rods 16 located inside the rocker arm 8. The slide rods 16 are slidably connected to the rocker arm 8. The top of one of the rocker arms 8 is fixedly connected with a drive motor 17. The output end of the drive motor 17 passes through the rocker arm 8 and is fixedly connected to the top of the extrusion rod 9. The top of the connecting frame 12 is set to be hollow. The top of the threaded sleeves 15 is fixedly connected with a limiting block 18 located inside the connecting frame 12. The limiting block 18 and the connecting frame 12 are slidably connected.

[0029] Specifically, during operation / use of this adsorption separation test device: the operator rotates the rotating wheel 14, driving the bidirectional screw 13 to rotate. The rotation of the bidirectional screw 13 causes the two side sleeves 15 to move outward along the screw. The sleeves 15 push the bottom end of the swing rod 8 outward through the slide rod 16. The swing rod 8 rotates around the pin on the connecting plate 7, causing the top pressing rod 9 to move away from the cylinder 4, releasing the clamping force on the sieve plate 5. When the pressing rod 9 is completely disengaged, the sliding constraint between the sieve plate 5 and the cylinder 4 is released. The operator slides along the inside of the cylinder 4 to pull out the old sieve plate 5, completing the disassembly, and then the new sieve plate 5 is removed. The sieve plate 5 is aligned with the slot of the cylinder body 4 and pushed smoothly into the inner side of the cylinder body 4 until the sieve plate 5 reaches the preset working position. When the sieve plate 5 is installed, the rotating wheel 14 is rotated in the opposite direction, and the bidirectional screw 13 drives the screw sleeve 15 to move inward. The slide rod 16 pulls the bottom end of the swing rod 8 to swing inward. The swing rod 8 rotates around the pin shaft, causing the extrusion rod 9 to move closer to the cylinder body 4, forming clamping pressure on the sieve plate 5. At the same time, the drive motor 17 is started to rotate forward, driving the extrusion rod 9 to rotate. The toothed column 11 and the toothed ring 10 of the sieve plate 5 are precisely engaged, which enhances the locking stability and can also improve the uniformity of airflow distribution.

[0030] 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.
