Description

Technical Field

[0001] This utility model relates to the field of high-efficiency visual dehydration and drying tube technology, specifically a high-efficiency visual dehydration and drying tube. Background Technology

[0002] Visual dehydration drying tubes are devices used in chemical experiments to dry gases or remove impurities from gases.

[0003] For example, a gas drying tube with authorization announcement number "CN210495833U" has a second vent located outside the drying chamber. A second airflow channel extends from inside the drying chamber to the inside of the upper cover and communicates with the second vent. The gas drying tube also includes a first metal filter and a second metal filter. The two ends of the first and second metal filters are connected to the upper cover and the base, respectively. The drying chamber is filled with color-changing silica gel desiccant to dry the gas. The gas drying tube is small in size and simple in structure, and has a good drying effect. However, in the use of the drying tube, the desiccant is placed outside the internal filter. At this time, the inside of the filter is hollow. In addition, the gas cannot stay inside the drying tube, and the gas will be directly discharged through the filter. This results in a short contact time and insufficient contact range between the gas and the desiccant, which reduces the dehydration effect of the drying tube and affects its normal use. Utility Model Content

[0004] The purpose of this invention is to solve the problem of reduced dehydration effect of the drying tube, which affects the normal use of the drying tube, and to propose a high-efficiency visual dehydration drying tube.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a high-efficiency visual dehydration and drying tube, including a straight tube and a second port. The second port is machined on the rear end face of the straight tube. A control structure is connected to the inner wall of the straight tube. A top cover is attached to the front of the straight tube. Fixing structures are connected to the left and right sides of the top cover. Groove plates are fixed to the front ends of the left and right sides of the straight tube.

[0007] Preferably, the control structure includes curved plates and round rods. The outer sides of the two curved plates are fixedly connected to the upper and lower sides of the inner wall of the straight tube, respectively. The front side of the curved plates is fixedly connected to the rear end face of the round rod. A mesh tube is inserted into the outer wall of the round rod, and a vertical plate is fixedly connected to the front of the inner wall of the mesh tube.

[0008] Preferably, the front of the outer wall of the mesh cylinder is in contact with the front of the curved plate.

[0009] Preferably, the front side of the top cover is machined with a first opening.

[0010] Preferably, the fixing structure includes straight plates and round blocks. The outer ends of the outer walls of the multiple straight plates are respectively fixed to the left and right sides of the top cover. The inner side of the straight plates is rotatably connected to the outer wall of the round blocks. A straight rod is fixed to the rear end face of the round blocks. A protruding rod is slidably connected to the outer wall of the straight rod. A spring is sleeved on the outer wall of the straight rod. The two ends of the spring are respectively fixed to the rear end face of the round blocks and the front face of the protruding rod.

[0011] Preferably, the outer wall of the protruding rod is inserted into the inner wall of the groove plate.

[0012] The present invention proposes a high-efficiency visual dehydration and drying tube with the following advantages: by controlling the structure to inject desiccant in front of the mesh cylinder, the desiccant fills the mesh cylinder behind the vertical plate. Then, the mesh cylinder is inserted into the straight tube, so that the round opening in front of the mesh cylinder is inserted into the outer wall of the round rod, so that the mesh cylinder is completely located inside the straight tube, forming a mesh cylinder wrapping stroke, which increases the contact area between the gas and the desiccant, improves the dehydration effect of the drying tube, and ensures the normal use of the drying tube.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] Please see Figure 1-5In this embodiment, a high-efficiency visual dehydration and drying tube includes a straight tube 1 and a second port 7. The rear end face of the straight tube 1 is machined with the second port 7. The inner wall of the straight tube 1 is connected to a control structure 2. The front side of the straight tube 1 is fitted with a top cover 5. The left and right sides of the top cover 5 are respectively connected to a fixing structure 3. The front ends of the left and right sides of the straight tube 1 are respectively fixed with a groove plate 4.

[0022] The control structure 2 includes curved plates 201 and round rods 202. The outer sides of the two curved plates 201 are fixed to the upper and lower sides of the inner wall of the straight pipe 1, respectively. The front side of the curved plates 201 is fixed to the rear end face of the round rods 202. A mesh tube 203 is inserted into the outer wall of the round rods 202. Granular desiccant is placed inside the mesh tube 203. When the mesh tube 203 is pulled forward, it can be separated from the outer wall of the round rods 202. The mesh tube 203 is made of stainless steel. A vertical plate 204 is fixed to the front of the inner wall of the mesh tube 203. The front of the outer wall of the mesh tube 203 is in contact with the front side of the curved plates 201.

[0023] By filling the desiccant into the front of the mesh cylinder 203 through the control structure 2, the desiccant fills the mesh cylinder 203 behind the vertical plate 204. Then, the mesh cylinder 203 is inserted into the straight tube 1, so that the round opening at the front of the mesh cylinder 203 is inserted into the outer wall of the round rod 202, so that the mesh cylinder 203 is completely inside the straight tube 1, forming a mesh cylinder wrapping stroke, which increases the contact area between the gas and the desiccant, improves the dehydration effect of the drying tube, and ensures the normal use of the drying tube.

[0024] The top cover 5 has a first opening 6 on its front side. The fixing structure 3 includes a straight plate 301 and a round block 302. The outer ends of the multiple straight plates 301 are fixedly connected to the left and right sides of the top cover 5 respectively. The inner side of the straight plate 301 is rotatably connected to the outer wall of the round block 302. The round block 302 rotates through the inner pin of the straight plate 301 under force. A straight rod 303 is fixedly connected to the rear end face of the round block 302. A protruding rod 304 is slidably connected to the outer wall of the straight rod 303. The protruding rod 304 slides back and forth through the outer wall of the straight rod 303 under force. A spring 305 is sleeved on the outer wall of the straight rod 303. The two ends of the spring 305 are fixedly connected to the rear end face of the round block 302 and the front side of the protruding rod 304 respectively. After the protruding rod 304 moves backward under force, it rebounds through the elastic force of the spring 305. The outer wall of the protruding rod 304 is inserted into the inner wall of the groove plate 4.

[0025] Working principle:

[0026] Dryer tube material filling:

[0027] The desiccant is poured into the front of the mesh cylinder 203, so that the desiccant fills the mesh cylinder 203 behind the vertical plate 204. Then, the mesh cylinder 203 is inserted into the inside of the straight tube 1, so that the round opening at the front of the mesh cylinder 203 is inserted into the outer wall of the round rod 202, so that the mesh cylinder 203 is completely inside the straight tube 1, forming a mesh cylinder wrapping stroke, which increases the contact area between the gas and the desiccant and improves the gas dehydration effect.

[0028] Dryer tube installation:

[0029] Make the rear of the top cover 5 fit against the front of the straight tube 1. Then, the protruding rod 304 is pulled backward on the outer wall of the straight rod 303, so that the protruding rod 304 stretches the spring 305. Then, the round block 302 rotates from the inside of the straight plate 301 to the outer wall of the straight tube 1, so that the outer wall of the protruding rod 304 is inserted into the inner wall of the groove plate 4. Then, the protruding rod 304 is released, the spring 305 loses its tension and provides a rebound force, so that the protruding rod 304 moves forward on the outer wall of the straight rod 303. At this time, the front of the outer wall of the protruding rod 304 abuts against the rear end face of the groove plate 4, thus completing the fixation of the top cover 5.

[0030] Drying tube usage:

[0031] The intake pipe is connected to the first port 6, and the exhaust pipe is connected to the second port 7. The gas enters the first port 6 through the intake pipe and then enters the straight pipe 1. At this time, the desiccant inside the mesh cylinder 203 will adsorb the water vapor in the gas. Then the gas is discharged through the mesh cylinder 203 at the second port 7.

[0032] Dryer tube material replacement:

[0033] The desiccant adsorption inside the mesh cylinder 203 can be observed through the straight tube 1. When replacing it, pull the protruding rod 304 backward to disengage it from the slot plate 4. Then, the round block 302 rotates from the inside to the outside of the straight plate 301, causing the straight rod 303 to rotate outward with the protruding rod 304, so that the protruding rod 304 disengages from the slot plate 4. Then, remove the top cover 5 from the straight tube 1. Next, pull the upright plate 204 forward to pull the mesh cylinder 203 out through the inner wall of the straight tube 1. Then, replace the desiccant inside the mesh cylinder 203. Finally, reinstall the mesh cylinder 203 and close the top cover 5 after performing the above operations.

[0034] Example 2:

[0035] Please see Figure 1-5 In this embodiment, a high-efficiency visual dehydration and drying tube further includes plugs 8, with the two plugs 8 respectively inserted into the inner walls of the first port 6 and the second port 7.

[0036] Working principle:

[0037] When placing the drying tube, insert the two plugs 8 into the inner walls of the first port 6 and the second port 7 respectively. The plugs 8 use their own rubber material to seal the tube.

[0038] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
