Description

Technical Field

[0001] This utility model relates to the field of chemical vessel clamping technology, and in particular to a clamping device for distillation vessels. Background Technology

[0002] Ammonium sulfate, after purification, can be used as a fertilizer. As a nitrogen fertilizer, nitrogen content is a crucial indicator of its quality, and it is typically determined by distillation. This determination usually requires a distillation apparatus, including a distillation flask, a splash-proof bulb, a condenser, and an absorption flask. The splash-proof bulb is a U-shaped tube, detachably connected at one end to the distillation flask and at the other end to one end of the condenser. The other end of the condenser is connected to the absorption flask. Since sodium hydroxide solution, which easily corrodes glass, is used during distillation, to prevent corrosion and subsequent adhesion of the apparatus, it is necessary to disassemble the apparatus as soon as possible after distillation. Conventional iron stands with claw-like clamps are not suitable for frequent assembly and disassembly of the distillation apparatus and can easily damage it due to improper handling.

[0003] Therefore, there is a need to provide a clamping device for distillation apparatus to solve the above problems. Utility Model Content

[0011] The second clamping block has a second recessed groove. The second clamping block can be connected to the first clamping block. The first groove and the second groove are spliced ​​together to form a clamping groove. The first clamping block and the second clamping block are close to each other so that the distillation flask / one neck of the anti-splash ball tube / the other neck of the anti-splash ball tube / the condenser tube are clamped and fixed in the clamping groove.

[0012] Preferably, the clamping assembly further includes:

[0013] A first locking member passes through the first clamping block and the second clamping block to connect the first clamping block and the second clamping block.

[0014] Preferably, there are two first locking members, which are located on opposite sides of the clamping groove.

[0015] Preferably, the clamping assembly further includes:

[0020] Preferably, the lifting mechanism includes a linkage assembly and a drive assembly, with multiple linkage assemblies spaced apart. Each linkage assembly includes:

[0021] A sliding rod, wherein the sliding rod is disposed on the mounting plate;

[0022] Two connecting rods are rotatably connected, one end of each connecting rod is rotatably connected to the support plate, the other end of one connecting rod is rotatably connected to the slide rod, and the other end of the other connecting rod is slidably connected to the slide rod. The drive assembly is configured to drive the other end of the other connecting rod to slide along the slide rod.

[0023] Preferably, the driving component includes:

[0024] A drive rod extends along the distribution direction of the linkage assembly, and the drive rod is connected to the other end of another connecting rod of the multiple sets of linkage assemblies;

[0031] This distillation apparatus clamping device includes support columns and lifting platforms. Two support columns are spaced apart along the X-axis, and two clamping components are spaced apart along the Z-axis. The two clamping components on one support column clamp one side of the neck of the distillation flask and the anti-splash bulb, respectively; the two clamping components on the other support column clamp the other side of the neck of the anti-splash bulb and the condenser. Two lifting platforms are spaced apart along the X-axis, and their height is adjustable along the Z-axis. One lifting platform holds an electric furnace to heat the distillation flask, while the other lifting platform supports the absorption flask. The support columns and clamping components securely hold the distillation flask, anti-splash bulb, and condenser, preventing the components from shaking or falling off during distillation, ensuring high operational safety. The adjustable height of the lifting platforms allows the device to accommodate distillation apparatus of different sizes, improving its versatility and adaptability. The contact level between the electric furnace and the distillation flask can be flexibly adjusted according to experimental needs, ensuring the lifting platform stably supports the absorption flask.

[0032] Compared to related technologies, this new method allows for the separate fixing of the distillation flask, anti-splash bulb, condenser, and absorption flask within the distiller's apparatus. When disassembly and cleaning are required, the connections between the distillation flask and one side of the anti-splash bulb's neck, between the other side of the anti-splash bulb's neck and the condenser, and between the condenser and the absorption flask are disconnected. The lifting platform carrying the electric furnace and absorption flask is then lowered, allowing for the direct and stable removal of the absorption flask. Finally, the individual clamping components are released to securely remove the distillation flask, anti-splash bulb, and condenser. This makes disassembly of the distiller's apparatus simpler, faster, and less difficult, reducing the risk of damage. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] When determining the nitrogen content in ammonium sulfate, a distillation apparatus of 100° is typically required, such as... Figure 1 As shown, the distillation apparatus 100 includes a distillation flask 1001, a splash-proof bulb 1002, a condenser 1003, and an absorption flask 1004. The splash-proof bulb 1002 is a U-shaped tube. One end of the splash-proof bulb 1002 is detachably connected to the distillation flask 1001, and the other end is detachably connected to one end of the condenser 1003. The other end of the condenser 1003 is connected to the absorption flask 1004. During the distillation process, a sodium hydroxide solution that easily corrodes glass is used. To prevent the interfaces of the distillation apparatus 100 from sticking together due to corrosion, the parts need to be disassembled as soon as possible after distillation. Conventional iron stands with claw-shaped clamps are not suitable for the frequent installation and removal of the distillation apparatus 100 and are easily damaged due to careless operation.

[0047] Therefore, such as Figure 2 , Figure 3As shown, this embodiment provides a clamping device for a distillation apparatus. This clamping device includes a support column 1 and a lifting platform 3. Two support columns 1 are spaced apart along the X-axis. Along the Z-axis, two clamping components 2 are spaced apart on the support column 1. The two clamping components 2 on one support column 1 clamp one side of the neck of the distillation flask 1001 and the anti-splash bulb 1002, respectively. The two clamping components 2 on the other support column 1 clamp the other side of the neck of the anti-splash bulb 1002 and the condenser 1003, respectively. Two lifting platforms 3 are spaced apart along the X-axis. The height of the lifting platforms 3 along the Z-axis is adjustable. An electric furnace is placed on one lifting platform 3 to heat the distillation flask 1001, and the other lifting platform 3 can support the absorption flask 1004. The distillation flask 1001, anti-splash bulb 1002, and condenser 1003 are securely clamped by the support column 1 and clamping assembly 2, preventing the components of the distillation apparatus 100 from shaking or falling off during distillation, thus ensuring high operational safety. The height-adjustable design of the lifting platform 3 allows the clamping device to adapt to distillation apparatus 100 of different sizes, improving the versatility and adaptability of the clamping device. The contact degree between the electric furnace and the distillation flask 1001 can be flexibly adjusted according to experimental needs, and the lifting platform 3 can stably support the absorption bottle 1004.

[0048] Compared with related technologies, this method allows the distillation flask 1001, anti-splash bulb 1002, condenser 1003, and absorption flask 1004 of the distillation apparatus 100 to be fixed separately. When the distillation apparatus 100 needs to be disassembled for cleaning, the connections between one neck of the distillation flask 1001 and the anti-splash bulb 1002, between the other neck of the anti-splash bulb 1002 and the condenser 1003, and between the condenser 1003 and the absorption flask 1004 are released. Then, the lifting platform 3 carrying the electric furnace and the absorption flask 1004 is lowered, allowing the absorption flask 1004 to be removed directly and stably. Then, each clamping component 2 is released to stably remove the distillation flask 1001, the anti-splash bulb 1002, and the condenser 1003. This makes the disassembly of the distillation apparatus 100 simpler and faster, reduces the difficulty of operation, and lowers the risk of damage to the distillation apparatus 100.

[0049] Specifically, such as Figure 2 As shown, the clamping assembly 2 includes a first clamping block 21 and a second clamping block 22. The first clamping block 21 is tunably connected to the support column 1 along the Z-axis and has a first groove. The second clamping block 22 has a second groove and can be connected to the first clamping block 21. The first groove and the second groove are joined to form a clamping groove 23. The first clamping block 21 and the second clamping block 22 are close to each other so that one neck of the distillation flask 1001 / splash-proof bulb tube 1002 / the other neck of the splash-proof bulb tube 1002 / condenser tube 1003 is clamped and fixed in the clamping groove 23.

[0050] The first clamping block 21 is adjustablely connected to the support column 1 along the Z-axis. The height of the first clamping block 21 can be adjusted as needed to accommodate different sizes of distillation vessels 100, so that each clamping component 2 can stably clamp each part of the distillation vessel 100, improving the versatility and flexibility of the clamping device. When the second clamping block 22 is connected to the first clamping block 21, the first groove and the second groove are spliced ​​to form a complete clamping groove 23. By bringing the first clamping block 21 and the second clamping block 22 closer to each other, the corresponding parts of the distillation vessel 100 are clamped and fixed in the clamping groove 23, ensuring the stability of the clamping and fixing of each part of the distillation vessel 100.

[0051] Optionally, such as Figure 2 As shown, the clamping assembly 2 also includes a first locking member 24, which passes through the first clamping block 21 and the second clamping block 22 to connect the first clamping block 21 and the second clamping block 22. When it is necessary to clamp the various components of the distillation apparatus 100, the various components of the distillation apparatus 100 are placed in the first groove of the first clamping block 21, and then the second clamping block 22 is spliced ​​to the first clamping block 21. The first locking member 24 passes through the first clamping block 21 and the second clamping block 22. By tightening the first locking member 24, the second clamping block 22 moves toward the first clamping block 21, so that the first clamping block 21 and the second clamping block 22 are connected and clamp the various components of the distillation apparatus 100. When it is necessary to disassemble the various components of the distillation apparatus 100, simply loosen the first locking member 24 to easily separate the first clamping block 21 and the second clamping block 22, thereby releasing the clamping of the various components of the distillation apparatus 100.

[0052] In one alternative embodiment, such as Figure 2 As shown, there are two first locking members 24, located on opposite sides of the clamping groove 23. The placement of one first locking member 24 on each opposite side of the clamping groove 23 ensures that the first clamping block 21 and the second clamping block 22 are subjected to uniform force during clamping, helping to reduce the offset or tilting of the first clamping block 21 and the second clamping block 22 due to excessive force on one side, thereby improving clamping stability.

[0053] Optionally, the first locking element 24 may be a bolt.

[0054] Optionally, such as Figure 2As shown, the clamping assembly 2 also includes a second locking member 25. The first clamping block 21 has a first mounting hole, and the support column 1 has multiple second mounting holes spaced apart along the Z-axis. The second locking member 25 passes through the first mounting hole and any of the second mounting holes to connect the first clamping block 21 to the support column 1. The first mounting hole of the first clamping block 21 is aligned with the corresponding second mounting hole on the support column 1, and the second locking member 25 is sequentially passed through the first mounting hole and the corresponding second mounting hole to tighten the second locking member 25, thereby securely connecting the first clamping block 21 to the support column 1 and ensuring that the first clamping block 21 will not shift or loosen.

[0055] Specifically, such as Figure 2 , Figure 3 As shown, the lifting platform 3 includes a support plate 31 and a mounting plate 32, which are spaced apart along the Z-axis. A lifting mechanism 33 connects the support plate 31 and the mounting plate 32, and the lifting mechanism 33 can drive the support plate 31 to move along the Z-axis. By driving the support plate 31 to move along the Z-axis through the lifting mechanism 33, the height of the support plate 31 can be adjusted.

[0056] In one optional embodiment, the lifting mechanism 33 includes a motor, the output shaft of which extends along the Z-axis direction and is connected to the support plate 31. The motor can drive the support plate 31 to move along the Z-axis direction.

[0057] In this embodiment, as Figure 2 , Figure 3 As shown, the lifting mechanism 33 includes a linkage assembly 331 and a drive assembly 332. Multiple linkage assemblies 331 are spaced apart. Each linkage assembly 331 includes a slide rod 3311 and two connecting rods. The slide rod 3311 is mounted on the mounting plate 32. The two connecting rods are rotatably connected. One end of each connecting rod is rotatably connected to the bearing plate 31. The other end of one connecting rod is rotatably connected to the slide rod 3311. The other end of the other connecting rod is slidably connected to the slide rod 3311. The drive assembly 332 is configured to drive the other end of the other connecting rod to slide along the slide rod 3311.

[0058] For ease of description, such as Figure 2 , Figure 3As shown, one connecting rod is named the first connecting rod 3312, and the other connecting rod is named the second connecting rod 3313. The first connecting rod 3312 and the second connecting rod 3313 form an X-shaped rotatable structure. In the initial state, the support plate 31 is at its lowest position, and the first connecting rod 3312 and the second connecting rod 3313 are at a certain angle. The other end of the second connecting rod 3313 is close to the end of the slide rod 3311. When it is necessary to raise the lifting platform 3, the drive assembly 332 pushes the other end of the second connecting rod 3313 to slide along the slide rod 3311 towards the first connecting rod 3312. At this time, the included angle between the first connecting rod 3312 and the second connecting rod 3313 gradually decreases, and the support plate 31 is gradually lifted and rises along the Z-axis. When it is necessary to lower the lifting platform 3, the drive assembly 332 pushes the other end of the second connecting rod 3313 to slide along the slide rod 3311 away from the first connecting rod 3312. At this time, the included angle between the first connecting rod 3312 and the second connecting rod 3313 gradually increases, and the support plate 31 is gradually lowered and descends along the Z-axis.

[0059] Multiple linkage components 331 are spaced apart and work synchronously to ensure the stability of the bearing plate 31 during the lifting process, improve the load-bearing capacity and stability of the lifting mechanism 33, and make the lifting mechanism 33 less prone to deformation or shaking.

[0060] Optionally, such as Figure 2 , Figure 3 As shown, the drive assembly 332 includes a drive rod 3321, a screw 3322, and a drive member 3323. The drive rod 3321 extends along the distribution direction of the connecting rod assembly 331, and the drive rod 3321 is connected to the other end of another connecting rod in the multiple sets of connecting rod assemblies 331. The screw 3322 is horizontally arranged with the slide rod 3311, and the screw 3322 is threadedly connected to the drive rod 3321. The screw 3322 is connected to the output end of the drive member 3323, and the drive member 3323 is configured to drive the screw 3322 to rotate. The drive rod 3321 is connected to the other end of the second connecting rod 3313 in the multiple linkage assemblies 331, realizing synchronous driving of the multiple linkage assemblies 331 and simplifying the structure of the drive assembly 332. The drive member 3323 drives the screw 3322 to rotate, and the rotation of the screw 3322 drives the drive rod 3321 to move along the length direction of the screw 3322, so that the drive rod 3321 can simultaneously drive the other end of the second connecting rod 3313 in the multiple linkage assemblies 331 to slide along the slide rod 3311. The conversion from rotary motion to linear motion is realized through the threaded connection, making the transmission path more direct and reducing energy loss. The screw 3322 transmission has self-locking property. When the drive member 3323 stops working, the screw 3322 can maintain its current position and prevent the support plate 31 from moving accidentally.

[0061] In one optional embodiment, an anti-slip layer is provided on the side of the support plate 31 facing away from the mounting plate 32. By providing the anti-slip layer, the electric furnace and the absorption bottle 1004 can be stably placed on the support plate 31, ensuring that the electric furnace can remain stable during lifting and lowering.

[0062] Alternatively, the anti-slip layer can be made of rubber, silicone, or the like.

[0063] In one alternative embodiment, such as Figure 2 As shown, the clamping device for this distillation apparatus also includes a base 4, with the support column 1 and the lifting platform 3 all mounted on the base 4. The base 4 serves as the supporting foundation for the entire clamping device for the distillation apparatus, providing a stable support surface so that the support column 1 and the lifting platform 3 can be stably placed on the base 4.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
