Description

Technical Field

[0001] The invention relates to the technical field related to aqueous solution processing, in particular to a micro-sample distillation instrument. Background Art

[0002] In the field of chemical and biological research and fine chemical production, distillation of solution samples is an important step to obtain pure products or analyze components. Among them, the steam condensation process plays a key role in product collection and quality assurance.

[0003] At present, the widely used steam condensation method is to use dry ice to cool the receiving flask to achieve rapid condensation of steam. However, this traditional method has exposed many problems in practical applications, which has greatly hindered the smooth progress of experiments and production.

[0004] From the perspective of convenience, operators must frequently wear protective gloves to add, replace, and perform related operations on dry ice. In some experiments or production scenarios that require continuous distillation, such frequent operations not only consume time and energy, but also interrupt the workflow and reduce work efficiency. Moreover, the process of preparing protective gloves before each operation and tidying up the gloves after the operation is cumbersome, which has a more significant impact on some experiments that require high operational continuity.

[0005] In terms of safety, dry ice is usually placed in exposed containers, which poses multiple risks. On the one hand, a large amount of carbon dioxide gas generated by the sublimation of dry ice accumulates in a limited space. If the ventilation conditions are not good, it is very easy for operators to experience dizziness, nausea, or even suffocation due to inhalation of excessive carbon dioxide. On the other hand, exposed dry ice containers lack effective protective measures and are prone to tipping over when people are walking or equipment is vibrating. Once the dry ice is tipped over, it will not only cause a waste of dry ice, but more seriously, dry ice that comes into contact with the human body will instantly freeze the skin, causing serious harm to the health of the operator.

[0006] In addition, the energy utilization efficiency of the existing dry ice cooling method is low. Since the dry ice is directly exposed to the environment, its refrigeration energy will quickly dissipate to the surrounding environment, a large amount of cold energy is wasted, and it cannot fully act on the cooling of the receiving flask, resulting in faster consumption of dry ice and increased experimental and production costs; at the same time, in order to maintain a certain cooling effect, the amount of dry ice used has to be increased, which further aggravates energy waste and operational inconvenience.

[0007] In some experiments or production processes that require high temperature control accuracy, the characteristic that the refrigeration effect of dry ice weakens over time makes it difficult to stably control the temperature of the receiving flask; temperature fluctuations will affect the condensation effect of steam, resulting in unstable product purity and output, which cannot meet the requirements of high-precision experiments and production.

[0008] In summary, the existing technology of using dry ice to cool the receiving flask for steam condensation has obvious shortcomings in convenience, safety and energy efficiency. There is an urgent need to develop a more efficient, convenient and safe steam condensation technology to meet the needs of scientific research and production.

[0009] Therefore, the present invention proposes a micro-sample distiller to solve the above problems. Summary of the invention

[0010] In view of this, the technical problem to be solved by the present invention is to propose a micro-sample distillation apparatus to solve the problems existing in the prior art.

[0011] To achieve the above-mentioned object, the present invention provides the following technical solution: a micro-sample distiller, comprising: a heating box, a distillation flask is placed in the heating box, a receiving flask is plugged into one side of the distillation flask, an auxiliary device is arranged on one side of the receiving flask, a protective component and a dry ice filling component are arranged between the heating box and the auxiliary device, and the dry ice filling component is located in front of the protective component; The protection component is used to ensure the safety of personnel during purification condensation; The dry ice filling assembly is used to assist operators in conveniently and safely filling dry ice during purification condensation.

[0012] As an improvement, the protective component includes a first fastening piece that is fastened to one side of the receiving flask, the first fastening piece is fixedly connected to a magnet group A, the first fastening piece is provided with an arc groove for placing heat insulation cotton, and the first fastening piece is provided with rubber buffer grooves at intervals.

[0013] As an improvement, a semi-arc threaded cavity A is fixedly connected to the bottom end face of the first fastening piece, a second fastening piece is fastened to the other side of the receiving flask, a magnet group B is fixedly connected to the second fastening piece, and the first fastening piece and the second fastening piece are fastened to form a fastening ball cavity.

[0014] As an improvement, a semi-arc threaded cavity B is fixedly connected to the bottom end surface of the second fastening piece, and the semi-arc threaded cavity A and the semi-arc threaded cavity B can constitute a threaded wire cavity. A spiral adjustment base is placed on one side of the heating box, and the semi-arc threaded cavity A and the semi-arc threaded cavity B constitute a threaded wire cavity and are threadedly adapted to the spiral adjustment base.

[0015] As an improvement, the dry ice filling assembly includes a transfer cavity fixedly connected to the second fastening member, and a filling strip opening is opened on the transfer cavity.

[0016] As an improvement, a push bar is slidably connected to the transfer cavity, a push rod is fixedly connected to the push bar, a spring is fixedly connected to the outer end surface of the transfer cavity, and a connecting bar is fixedly connected to the outer end of the spring.

[0017] As an improvement, a dry ice storage bin is fixedly connected to the transfer cavity.

[0018] As an improvement, a temperature sensor is fixedly connected in the buckling ball cavity, a conical member is fixedly connected in the buckling ball cavity, a partition net is fixedly connected to the bottom end of the conical member, and a through vent is opened on the second buckling member.

[0019] As an improvement, a through air inlet opening is provided on the second fastening member, and a blocking spacer is fixedly connected to the air inlet opening.

[0020] Compared with the prior art, the present invention provides a trace sample distiller, which has the following beneficial effects: 1. The present invention can effectively close the first fastening part and the second fastening part by adding a magnet group, thereby providing conditions for the steam condensation of the receiving flask. The above design can bring the following benefits: Enhanced installation convenience: The application of the magnet group greatly simplifies the installation process of the receiving flask, avoiding the cumbersome tightening, snap-on and other operations required in the prior art. Now, it is only necessary to bring the first fastening part with the receiving flask close to the corresponding position of the second fastening part, and the attraction of magnet group A and magnet group B can quickly guide the two to accurately dock and tightly close. In experiments or production scenarios where the receiving flask needs to be replaced frequently, this quick installation method greatly saves operation time and improves work efficiency; moreover, even in an environment with limited space and inconvenient operation, the automatic adsorption characteristics of the magnet can allow the operator to easily complete the installation, reducing the difficulty of operation, and is more friendly to novice operators.

[0021] Improve the stability of the device: The strong suction force generated by the magnet group ensures that the first and second fasteners fit tightly together, so that the receiving flask is firmly fixed during the entire steam condensation process. This effectively avoids the loosening and falling of the receiving flask due to device vibration and external force collision factors, and ensures the continuity of steam condensation. In a complex operating environment, such as a production workshop with machine vibration and frequent personnel movement, a stable installation can prevent steam leakage and deterioration of condensation effect caused by flask shaking, ensuring the collection efficiency and quality of the product.

[0022] Optimize steam condensation effect: The tightly closed first and second fasteners cooperate with the sealing effect of the magnet group to reduce the entry of external heat. During the steam condensation process, this helps to maintain the low temperature environment around the receiving flask, so that the coldness of the dry ice can be more effectively used for steam condensation, further improving the utilization efficiency of dry ice. At the same time, the stable installation ensures that the position of the receiving flask is fixed, and the steam can enter the flask more smoothly and condense fully, reducing the loss of steam during the transmission process, improving the effect of steam condensation, and thus increasing the collection rate of the product.

[0023] Improve the versatility and scalability of the equipment: This convenient and stable installation design has good versatility and can be adapted to receiving flasks of various specifications and materials, which provides convenience for different experimental or production needs, and does not require customized complex installation equipment for different types of receiving flasks. At the same time, the design facilitates equipment upgrades and expansions, and can easily add more functional modules, such as condensation efficiency monitoring devices, steam flow control devices, etc., to further improve the performance and application range of the equipment.

[0024] 2. The present invention designs the storage container for dry ice under the receiving flask into a conical container. Compared with square or hemispherical containers, it has significant advantages in dry ice utilization efficiency, condensation effect improvement, operational convenience, space utilization and stability.

[0025] Improve the utilization efficiency of dry ice: The conical design of the cone makes the dry ice in the container more concentrated at the bottom of the receiving flask. Since the cold air generated by the sublimation of dry ice has a high density, it will naturally sink. The shape of the cone guides the cold air to flow downward along the cone wall, which can act on the receiving flask more directly and efficiently, reduce heat loss, and improve the cooling effect on the receiving flask, thereby improving the utilization efficiency of dry ice and reducing the cost of dry ice consumption.

[0026] Enhanced condensation effect: The large amount of low-temperature gas generated by the sublimation of dry ice concentrated at the bottom of the receiving flask can form a more stable and low-temperature environment in the conical space. This stable low-temperature environment is conducive to faster and full condensation of steam, improving the condensation efficiency of steam, making the collection of products more efficient, reducing steam escape losses, and improving the collection rate of products.

[0027] Easy to clean and replace dry ice: The conical structure of the cone makes it easier to clean dry ice. When the dry ice needs to be replaced, the residual dry ice and melted water are easier to pour out of the cone and less likely to remain. Compared with the corner residue of square containers and the problem of hemispherical containers being difficult to clean thoroughly, the conical state of the cone can reduce the residual dry ice, reduce the difficulty of cleaning, and improve the convenience and efficiency of operation.

[0028] Improved operational safety: When adding and replacing dry ice, the shape of the cone reduces the contact area between the operator's hand and the dry ice. Since the temperature of dry ice is extremely low, reducing the contact area can reduce the risk of frostbite for the operator and improve safety during operation.

[0029] 3. The overall design of the present invention can bring the following benefits to the work: Simplified operation process: The operator no longer needs to manually touch the dry ice for filling. The operator only needs to use the signal from the temperature sensor to make the push rod move back and forth in a straight line in the transfer cavity to complete the dry ice delivery and filling process, which greatly simplifies the operation process and saves time and labor costs.

[0030] Enhanced safety and avoidance of frostbite risk: Operators do not need to directly contact dry ice, eliminating the risk of frostbite caused by contact with dry ice and ensuring the personal safety of operators; at the same time, the protective shell composed of the first and second fasteners, the arc groove for placing the thermal insulation cotton, and the rubber buffer groove are safely added, which effectively prevents the risk of explosion caused by the high-pressure gas generated by the sublimation of dry ice, as well as the fire hazard caused by dry ice leakage.

[0031] Improve the utilization rate of dry ice and reduce the loss of dry ice sublimation: The double-layer insulation structure composed of the arc groove for placing the insulation cotton and the rubber buffer groove can greatly reduce the sublimation speed of dry ice during use and reduce the waste of dry ice.

[0037] in: The protection component 5 is used to ensure the safety of personnel when purifying condensation.

[0038] Magnet group A502 is used in conjunction with magnet group B507.

[0039] When in use, the receiving flask 3 is snap-fitted and stabilized in the snap-fit ​​ball cavity 508 .

[0040] The spiral adjustment base 510 is mainly used in conjunction with the threaded thread cavity composed of the semi-arc thread cavity A505 and the buckled ball cavity 508 to adjust the overall height of the device.

[0041] For further examples, please refer to Figures 5 to 7 As shown: The dry ice filling assembly 6 is used to assist the operator to conveniently and safely fill dry ice during purification and condensation. The dry ice filling assembly 6 includes a transfer cavity 601 fixedly connected to the second buckle 506, a filling strip opening 602 is opened on the transfer cavity 601, a push strip 603 is slidably connected in the transfer cavity 601, a push rod 604 is fixedly connected to the push strip 603, a spring 605 is fixedly connected to the outer end surface of the transfer cavity 601, and the outer end of the spring 605 is fixedly connected There is a connecting strip 606, a dry ice storage bin 607 is fixedly connected to the transfer cavity 601, a temperature sensor 608 is fixedly connected in the buckling ball cavity 508, a conical member 609 is fixedly connected in the buckling ball cavity 508, a partition net 610 is fixedly connected to the bottom end of the conical member 609, a through air vent 611 is opened on the second buckling member 506, a through air inlet port 612 is opened on the second buckling member 506, and a blocking partition strip 613 is fixedly connected to the air inlet port 612.

[0042] in: The dry ice filling assembly 6 is used to assist the operator to conveniently and safely fill dry ice during purification condensation.

[0043] The temperature sensor 608 is mainly used to monitor the temperature in the buckled ball cavity 508, so as to remind relevant personnel to replenish dry ice through an external reminder.

[0044] The dry ice vapor in the conical member 609 rises and quickly enters the receiving flask 3 which is very close. The receiving flask 3 is usually placed in a cooling environment such as a dry ice bath. The vapor is quickly condensed into liquid at low temperature, thereby obtaining an evaporated product.

[0045] The partition net 610 is used to prevent the dry ice in the cone 609 from falling from the bottom end thereof.

[0046] When the dry ice needs to be replaced, the remaining dry ice and melted water are more easily transferred through the air vent 611 and are less likely to remain.

[0047] The blocking spacer 613 is mainly used to ensure that the dry ice in the transfer chamber 601 does not enter the conical member 609 through the air inlet port 612 during the non-pushing period of dry ice.

[0048] Everything in the above example works like this: In the initial state: Insulation cotton is placed in the arc groove 503 to maintain the temperature of the dry ice in the conical part 609, and a rubber strip is plugged in the rubber buffer groove 504. Due to the adsorption of the magnet group A502 and the magnet group B507, the threaded cavity composed of the semi-arc threaded cavity A505 and the buckling ball cavity 508 located below the first buckle 501 and the second buckle 506 is in a threaded matching state with the spiral adjustment base 510; dry ice is arranged in the dry ice storage bin 607; the filling strip port 602 is blocked by the push strip 603, and the spring 605 is in an unstressed state.

[0049] The following is the working process of protection component 5: When in use, since the first fastening member 501 and the second fastening member 506 are magnetically matched through the magnet group A502 and the magnet group B507 arranged thereon, the fastening ball cavity 508 formed by them can cover the receiving flask 3 therein. Furthermore, when the dry ice in the conical member 609 performs a cold bath treatment on the steam in the receiving flask 3, since the arc groove 503 for placing the heat insulation cotton is plugged with the heat insulation cotton, the temperature of the dry ice in the conical member 609 will not cause harm to external personnel through the first fastening member 501. In addition, the rubber strip in the rubber buffer groove 504 can serve as a buffer layer to absorb possible dry ice impact, thereby preventing the dry ice from hitting the first fastening member 501 and the magnet group A502 and causing cracking and splashing. Furthermore, by adding a magnet group, the first fastening member 501 and the second fastening member 506 can be effectively closed, providing conditions for the steam condensation work of the receiving flask 3 and enhancing the convenience of installation; the application of the magnet group greatly simplifies the installation process of the receiving flask 3, avoiding the cumbersome tightening, snapping and other operations required in the prior art. Now, it is only necessary to bring the first fastening member 501 with the receiving flask 3 close to the corresponding position of the second fastening member 506, and the attraction of the magnet group A502 and the magnet group B507 can quickly guide the two to accurately dock and tightly close. In experimental or production scenarios where the receiving flask 3 needs to be frequently replaced, this quick installation method greatly saves operation time and improves work efficiency; moreover, even in an environment with limited space and inconvenient operation, the automatic adsorption characteristics of the magnet can allow operators to easily complete the installation, reducing the difficulty of operation and being more friendly to novice operators; Improve the stability of the device: The strong suction force generated by the magnet group ensures that the first fastening piece 501 and the second fastening piece 506 fit tightly together, so that the receiving flask 3 is firmly fixed during the entire steam condensation process. This effectively avoids the loosening and falling of the receiving flask 3 due to device vibration and external force collision factors, and ensures the continuity of the steam condensation work. In a complex use environment, such as a production workshop with machine vibration and frequent personnel movement, a stable installation can prevent steam leakage and deterioration of the condensation effect caused by the shaking of the flask, thereby ensuring the collection efficiency and quality of the product; Optimize the steam condensation effect: The tightly closed first fastener 501 and the second fastener 506 cooperate with the sealing effect of the magnet group to reduce the entry of external heat. During the steam condensation process, this helps to maintain the low temperature environment around the receiving flask 3, so that the cold energy of the dry ice can be more effectively used for steam condensation, further improving the utilization efficiency of the dry ice. At the same time, the stable installation ensures that the position of the receiving flask 3 is fixed, and the steam can enter the flask more smoothly and be fully condensed, which reduces the loss of steam during the transmission process, improves the effect of steam condensation, and thus improves the collection rate of the product; Improve the versatility and scalability of the equipment: This convenient and stable installation design has good versatility and can be adapted to receiving flasks 3 of various specifications and materials, which provides convenience for different experimental or production needs, and does not require customized complex installation equipment for different types of receiving flasks 3. At the same time, this design facilitates equipment upgrades and expansions, and can easily add more functional modules, such as condensation efficiency monitoring devices, steam flow control devices, etc., to further improve the performance and application range of the equipment.

[0050] Please refer to the above working process Figures 1 to 5 .

[0051] The following is the working process of the dry ice filling assembly 6: Furthermore, as the temperature sensor 608 detects the temperature of the dry ice at the conical member 609 in the buckled ball cavity 508, when the temperature is lower than the required process requirement, the temperature sensor 608 will remind the relevant personnel through the external prompter that the dry ice needs to be replenished. At this time, the relevant personnel only need to pull the connecting strip 606, and the connecting strip 606 will pull the filling strip opening 602 through the fixedly connected pushing rod 604, so that the pushing strip 603 that originally blocked the filling strip opening 602 can unblock the filling strip opening 602. At this time, the spring 605 is stretched, and the dry ice storage bin 607 is filled with dry ice. The dry ice will fall into the transfer cavity 601 through the filling strip opening 602. Furthermore, at this time, the push rod 604 is pushed, and the push rod 604 will push the dry ice in the transfer cavity 601 to the direction of the second fastening member 506 with the push strip 603. At this time, the spring 605 is compressed. Furthermore, with the push of the push strip 603, the dry ice will eventually pass through the air inlet 612 and break the blockage of the blocking strip 613 to enter the conical member 609 in the fastening ball cavity 508 composed of the first fastening member 501 and the second fastening member 506, thereby completing the filling of the dry ice. Furthermore, by designing the storage container for holding dry ice under the receiving flask 3 into a conical container, the utilization efficiency of dry ice can be improved; the conical design of the conical member 609 makes the dry ice in the container more concentrated at the bottom of the receiving flask 3. Since the cold air generated by the sublimation of dry ice has a high density, it will sink naturally. The shape of the conical member 609 guides the cold air to flow downward along the cone wall, which can act on the receiving flask 3 more directly and efficiently, reduce heat loss, and improve the cooling effect on the receiving flask 3, thereby improving the utilization efficiency of dry ice and reducing the cost of dry ice consumption; Enhanced condensation effect: The large amount of low-temperature gas generated by the sublimation of dry ice concentrated at the bottom of the receiving flask 3 can form a more stable and low-temperature environment in the conical space. This stable low-temperature environment is conducive to faster and full condensation of steam, improves the condensation efficiency of steam, makes the collection of products more efficient, reduces steam escape loss, and improves the collection rate of products; Easy to clean and replace dry ice: The conical structure of the conical part 609 makes it easier to clean dry ice. When the dry ice needs to be replaced, the residual dry ice and melted water are easier to pour out of the conical part 609 and are not easy to remain. Compared with the problem of residual corners in square containers and the problem of hemispherical containers being difficult to clean thoroughly, the conical state of the conical part 609 can reduce the residual dry ice, reduce the difficulty of cleaning, and improve the convenience and efficiency of operation; Improved operational safety: During the process of adding and replacing dry ice, the shape of the conical member 609 reduces the contact area between the operator's hand and the dry ice. Since the temperature of dry ice is extremely low, reducing the contact area can reduce the risk of frostbite for the operator and improve safety during operation.

[0052] Please refer to the above working process Figures 5 to 7 .

[0053] Furthermore, the overall design can simplify the operation process; the operator no longer needs to manually touch the dry ice for filling, and only needs to use the signal from the temperature sensor 608 to make the push bar 603 perform reciprocating linear motion in the transfer cavity 601 through the push rod 604 to complete the dry ice delivery and filling process, which greatly simplifies the operation process and saves time and labor costs. Enhanced safety and avoidance of frostbite risk: Operators do not need to directly contact dry ice, eliminating the risk of frostbite caused by contact with dry ice and ensuring the personal safety of operators; at the same time, the protective shell composed of the first fastening member 501 and the second fastening member 506, the arc groove 503 for placing the heat insulation cotton, and the rubber buffer groove 504 are safely added to effectively prevent the risk of explosion caused by the high-pressure gas generated by the sublimation of dry ice, as well as the fire hazard caused by the leakage of dry ice; Improve the utilization rate of dry ice and reduce the loss of dry ice sublimation: the double-layer insulation structure composed of the arc groove 503 for placing the heat insulation cotton and the rubber buffer groove 504 can greatly reduce the sublimation speed of dry ice during use and reduce the waste of dry ice.
