Description

Technical Field

[0001] This invention belongs to the technical field of nitrogen dryers, specifically, this invention relates to a protective device for a nitrogen dryer. Background Technology

[0002] In many fields such as chemical analysis, biopharmaceuticals, and food testing, nitrogen purging apparatus is a commonly used experimental device. It mainly uses nitrogen gas to purge the sample solution, thereby rapidly evaporating and concentrating the solution to achieve the purpose of separating and purifying the sample.

[0003] However, some nitrogen dryers currently on the market have problems that urgently need to be solved in practical use. Regarding safety features, most nitrogen dryers are directly exposed when not in operation. Since experimental environments are often complex and contain various potential hazards, such as dust, falling debris, and accidental collisions, this not only easily causes dirt to accumulate on the instrument surface, affecting its appearance and cleanliness, but more seriously, it may damage internal components, thus affecting the performance and lifespan of the nitrogen dryer. Once the instrument malfunctions, it will not only delay the experimental process but may also cause the loss of experimental data and economic losses. In terms of height adjustment, most existing nitrogen dryers have a fixed height or only limited adjustment methods. However, different users have different heights, and instruments with a fixed height cannot meet everyone's comfortable operation needs. For taller users, it may be necessary to bend over for a long time, which can easily lead to physical fatigue. For shorter users, additional auxiliary tools may be needed to raise their position, which not only increases the complexity of operation, but may also bring safety hazards. An inappropriate operating height will affect the user's operating experience and experimental efficiency, and may even lead to increased experimental errors due to inconvenience in operation.

[0019] Figure 1 This is a schematic diagram of the structure of the protective device for the nitrogen dryer in an embodiment of the present invention. Figure 1 ; Figure 2 This is a schematic diagram of the structure of the protective device for the nitrogen dryer in an embodiment of the present invention. Figure 2 ; Figure 3 This is a schematic diagram of the structure of the protective device for the nitrogen dryer in an embodiment of the present invention. Figure 3 .

[0020] like Figure 1 , Figure 2 as well as Figure 3As shown, the nitrogen dryer protective device provided by the present invention includes a workbench 10, a protective cover unit 20, a lifting unit 30, and a nitrogen dryer body 40. The workbench 10 includes a base plate 11 and a lifting plate 12 disposed on the base plate 11. The protective cover unit 20 is movably disposed on the base plate 11. The protective cover unit 20 can prevent the nitrogen dryer body 40 from being directly exposed to the outside when not in operation, and can prevent the surface of the nitrogen dryer body 40 from being contaminated with dirt, which is beneficial to improving the performance, appearance cleanliness and service life of the nitrogen dryer body 40. The lifting unit 30 is disposed on the base plate 11 and connected to the lifting plate 12. The nitrogen dryer body 40 is disposed on the lifting plate 12. The lifting unit 30 can adjust the height of the nitrogen dryer body 40 according to the height of the test personnel, improving the test personnel's operating experience and experimental efficiency.

[0021] The workbench 10 also includes a support assembly 13, which includes a support column 131, a support plate 132, and casters 133. One end of the support column 131 is connected to the base plate 11, and the other end of the support column 131 is connected to the support plate 132. The casters 133 are mounted on the support plate 132. The four sets of support assemblies 13 are respectively mounted at the four corners of the base plate 11 to facilitate the movement of the nitrogen drying instrument protective device provided by the present invention.

[0022] Figure 4 This is a schematic diagram of the structure of the workbench in an embodiment of the present invention; Figure 5 This is a schematic diagram of the positioning component in an embodiment of the present invention.

[0023] like Figure 4 and Figure 5 As shown, the workbench 10 also includes a positioning assembly 14, which includes a positioning sleeve 141, a positioning screw 142, a positioning disk 143, and a rubber pad 144. The positioning sleeve 141 is mounted on the base plate 11. One end of the positioning screw 142 is rotatably inserted into the positioning sleeve 141, and the other end of the positioning screw 142 is connected to the positioning disk 143. The rubber pad 144 is mounted on the positioning disk 143, and a lever 145 is mounted on the positioning disk 143. When the nitrogen dryer protective device is moved to a suitable working position, the pushing and pulling of the nitrogen dryer protective device is stopped. The positioning disk 143 is rotated by the lever 145. The rotation of the positioning disk 143 drives the positioning screw 142, which is coaxially fixed with it, to rotate. The positioning screw 142 moves downward while rotating. The positioning screw 142 moves downward until the rubber pad 144 on the positioning disk 143 is in close contact with the ground. The rotation of the positioning disk 143 is then stopped, and the nitrogen dryer protective device is stably positioned in a suitable working position. The base plate 11 is equipped with a push-pull handle 15, which makes it easy to support and push the protective device of the nitrogen dryer to a suitable working position.

[0024] Figure 6This is a schematic diagram of the structure of the protective cover body in an embodiment of the present invention; Figure 7 This is a schematic diagram of the structure of the adjustment drive component in an embodiment of the present invention. Figure 1 ; Figure 8 This is a schematic diagram of the structure of the adjustment drive component in an embodiment of the present invention. Figure 2 .

[0025] like Figure 6 , Figure 7 as well as Figure 8 As shown, the protective cover unit 20 includes a protective cover body 21 and an adjustment drive assembly 22 connected to the protective cover body 21. The two protective cover bodies 21 are located on both sides of the nitrogen dryer body 40. The adjustment drive assembly 22 is set on the base plate 11. The protective cover body 21 is in the shape of a cuboid shell. The adjustment drive assembly 22 is used to adjust the distance between the two protective cover bodies 21. The two protective cover bodies 21 are close to each other and splice the entire shell, covering the outside of the nitrogen dryer body 40. This can prevent the nitrogen dryer body 40 from being directly exposed to the outside when it is not in operation, and can prevent the surface of the nitrogen dryer body 40 from being contaminated with dirt. This is beneficial to improving the performance, appearance cleanliness and service life of the nitrogen dryer body 40.

[0026] The adjustment drive assembly 22 includes an adjustment drive motor 221, a mounting plate 222, a bidirectional lead screw 223, a first connecting rod 224, and a second connecting rod 225. The mounting plate 222 is mounted on the base plate 11, and the adjustment drive motor 221 is mounted on the mounting plate 222. The motor shaft of the adjustment drive motor 221 is connected to the bidirectional lead screw 223 via gear transmission, enabling the adjustment drive motor 221 to drive the bidirectional lead screw 223 to rotate. The ends of the bidirectional lead screw 223 are rotatably mounted on the mounting plate 222. The two ends of the bidirectional lead screw 223 have opposite thread directions. The first connecting rod 224 is connected via a threaded connection. The first connecting rod 224 and the second connecting rod 225 are rotatably mounted on the bidirectional lead screw 223 via a threaded connection. Both the first connecting rod 224 and the second connecting rod 225 are L-shaped and are connected to the two protective cover bodies 21 respectively. The first connecting rod 224 and the second connecting rod 225 are respectively mounted on two sections of the bidirectional lead screw 223 with opposite thread directions, so that when the bidirectional lead screw 223 rotates, the first connecting rod 224 and the second connecting rod 225 move closer to or further away from each other, thereby adjusting the distance between the two protective cover bodies 21.

[0027] The base plate 11 is provided with a limiting slide groove 111, and the adjustment drive assembly 22 also includes a limiting slider 226. The limiting slider 226 is slidably disposed in the limiting slide groove 111. The two limiting sliders 226 are respectively connected to the first connecting rod 224 and the second connecting rod 225, so that the first connecting rod 224 and the second connecting rod 225 can slide smoothly, ensuring that the protective cover body 21 can move smoothly and improving the reliability of the structure.

[0028] Figure 9 This is a schematic diagram of the lifting unit in an embodiment of the present invention. Figure 1 ; Figure 10 This is a schematic diagram of the lifting unit in an embodiment of the present invention. Figure 2 .

[0029] like Figure 9 and Figure 10 As shown, the lifting unit 30 includes a lifting drive motor 31, a lifting screw 32, a lifting block 33, a connecting rod 34, and a vertical plate 35. The vertical plate 35 is mounted on the base plate 11. The lifting drive motor 31 is mounted on the vertical plate 35 and connected to the lifting screw 32. The lifting block 33 is movably fitted onto the lifting screw 32 via a threaded connection. One end of the connecting rod 34 is connected to the lifting block 33, and the other end of the connecting rod 34 is connected to the lifting plate 12. The vertical plate 35 is L-shaped and has a lifting groove 351. One end of the lifting block 33 is slidably mounted in the lifting groove 351. The base plate 11 has a lifting hole 112, and the connecting rod 34 is movably inserted into the lifting hole 112.

[0030] When the height of the nitrogen dryer body 40 needs to be adjusted, the lifting drive motor 31 starts, and the output shaft of the lifting drive motor 31 rotates, driving the lifting screw 32 to rotate, which in turn drives the lifting block 33 and connecting rod 34 to move upward. The lifting plate 12 moves upward, which in turn drives the nitrogen dryer body 40 to move upward. This allows the height of the nitrogen dryer body 40 to be adjusted according to the height of the experimenter, improving the operator's experience and experimental efficiency. After the nitrogen dryer body 40 moves to the appropriate height, it is used to dry and concentrate the sample. After drying and concentration are completed, the lifting drive motor 31 reverses, and the nitrogen dryer body 40 resets. At the same time, the two protective cover bodies 21 move closer together and fit together, so that the nitrogen dryer body 40, when not in operation, is located inside the two protective cover bodies 21.

[0031] The nitrogen dryer protective device provided by this invention includes a workbench 10, a protective cover unit 20, a lifting unit 30, and a nitrogen dryer body 40. The workbench 10 includes a base plate 11 and a lifting plate 12 disposed on the base plate 11. The protective cover unit 20 is movably disposed on the base plate 11. The protective cover unit 20 can prevent the nitrogen dryer body 40 from being directly exposed to the outside when not in operation, and can prevent the surface of the nitrogen dryer body 40 from being contaminated with dirt, which is beneficial to improving the performance, appearance cleanliness, and service life of the nitrogen dryer body 40. The lifting unit 30 is disposed on the base plate 11 and connected to the lifting plate 12. The nitrogen dryer body 40 is disposed on the lifting plate 12. The lifting unit 30 can adjust the height of the nitrogen dryer body 40 according to the height of the test personnel, improving the test personnel's operating experience and experimental efficiency.

[0032] When the height of the nitrogen dryer body 40 needs to be adjusted, the lifting drive motor 31 starts, and the output shaft of the lifting drive motor 31 rotates, driving the lifting screw 32 to rotate, which in turn drives the lifting block 33 and connecting rod 34 to move upward. The lifting plate 12 moves upward, which in turn drives the nitrogen dryer body 40 to move upward. This allows the height of the nitrogen dryer body 40 to be adjusted according to the height of the experimenter, improving the operator's experience and experimental efficiency. After the nitrogen dryer body 40 moves to the appropriate height, it is used to dry and concentrate the sample. After drying and concentration are completed, the lifting drive motor 31 reverses, and the nitrogen dryer body 40 resets. At the same time, the two protective cover bodies 21 move closer together and fit together, so that the nitrogen dryer body 40, when not in operation, is located inside the two protective cover bodies 21.

[0033] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
