Description

Technical Field

[0001] This utility model relates to the field of adsorption instruments, specifically providing a heating furnace and an adsorption instrument. Background Technology

[0002] In adsorption analyzers, the heating furnace is primarily used for sample pretreatment. Heating removes moisture, gaseous contaminants, and volatile impurities from the sample surface and pores, ensuring sufficient contact between the target gas and the sample during subsequent adsorption tests. This allows for accurate measurement of parameters such as specific surface area and pore size distribution. After heating, the sample tube must be manually transferred to room temperature for natural cooling. Only after the temperature has dropped to a safe range can it be moved to the adsorption testing environment to prevent breakage due to sudden temperature changes. However, the heated sample tube is extremely hot, posing a risk of burns during manual transfer, and natural cooling is time-consuming, severely impacting experimental efficiency.

[0003] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0004] To address at least one problem in the prior art, namely the safety hazards during sample tube transfer and the time-consuming nature of natural cooling methods affecting experimental efficiency, this application provides a heating furnace, the heating furnace comprising:

[0008] In the preferred embodiment of the above-mentioned heating furnace, the baffle assembly includes a baffle and a connecting shaft, the connecting shaft being disposed in the heating channel near the cooling component; the baffle is disposed on the connecting shaft and is configured to allow the heating channel to be disconnected from or connected to the outlet.

[0009] In the preferred embodiment of the above-mentioned heating furnace, the connecting shaft is arranged along the axial direction of the heating channel, so that the baffle can move between a first position and a second position along the axial direction of the heating channel.

[0010] When the baffle is in the first position, it can disconnect the heating channel and the outlet; when the baffle is in the second position, it can connect the heating channel and the outlet.

[0011] In the preferred embodiment of the above-mentioned heating furnace, the heating channel includes a first channel and a second channel that are interconnected.

[0016] In the preferred embodiment of the above-mentioned heating furnace, the baffle assembly further includes a support, which is disposed in the heating channel near the cooling assembly; and

[0018] In the preferred embodiment of the above-mentioned heating furnace, the connecting shaft is arranged along the radial direction of the heating channel, and the baffle is rotatably arranged on the connecting shaft and is configured to be able to rotate between a third position and a fourth position.

[0019] When the baffle is in the third position, the baffle is in contact with the inner wall of the heating channel; when the baffle is in the fourth position, the angle between the baffle and the radial direction of the heating channel is greater than 0°.

[0020] In the preferred embodiment of the above-mentioned heating furnace, the number of heating channels is at least one.

[0021] In the preferred embodiment of the above-mentioned heating furnace, the heating assembly includes a heat-conducting block and a heating element, wherein the heating channel is formed on the heat-conducting block; the heating element is disposed on the outer wall of the heat-conducting block or inside the heat-conducting block.

[0022] In the preferred embodiment of the heating furnace described above, the heating assembly further includes a first heat insulation component, which has an annular structure and is fitted over the cooling assembly.

[0023] In the preferred embodiment of the heating furnace described above, the heating component further includes a second heat insulation component, which is disposed on the side of the heat-conducting block away from the cooling component, and has a third channel communicating with the heating channel.

[0026] In the preferred embodiment of the above-mentioned heating furnace, the heat insulation sheet is made of an elastic material.

[0027] In the preferred embodiment of the heating furnace described above, the heating component further includes a third heat insulation component, which is disposed on the side of the heat-conducting block near the cooling component, and has a fourth channel communicating with the heating channel.

[0028] In the preferred embodiment of the heating furnace described above, the heating furnace further includes a temperature measuring element, which is disposed on the heat-conducting block.

[0029] In the preferred embodiment of the above-mentioned heating furnace, the cooling component is a fan cooling component or an air compressor cooling component.

[0030] In the preferred embodiment of the heating furnace described above, the heating furnace further includes a protective cover, which is fitted over the heating component and / or the cooling component.

[0031] In the preferred embodiment of the heating furnace described above, the protective cover includes at least two connecting covers, and two adjacent connecting covers are detachably connected.

[0032] This application also provides an adsorption apparatus, which includes the heating furnace described in any of the above preferred technical solutions.

[0033] Those skilled in the art will understand that the heating furnace of this application, by setting a cooling component on one side of the heating component and setting a baffle component in the heating channel of the heating component, can control the connection state between the heating channel and the outlet of the cooling component. After the heating furnace has heated the sample in the sample tube, the baffle component can connect the heating channel and the outlet of the cooling component, thereby enabling the cooling airflow generated by the cooling component to quickly cool the sample tube, improving the cooling efficiency. This avoids the safety hazards during the sample tube transfer process and solves the problem that the natural cooling method is time-consuming and affects the experimental efficiency.

[0034] Furthermore, by setting a connecting shaft within the heating channel and placing a baffle on this connecting shaft, the baffle can move between a first position and a second position along the axial direction of the heating channel under the action of the connecting shaft. When the baffle is in the first position, the connection between the heating channel and the outlet is disconnected, ensuring temperature uniformity within the heating channel. When the baffle is in the second position, the heating channel and the outlet of the cooling component are connected, allowing the cooling airflow generated by the cooling component to rapidly cool the sample tube, thus improving cooling efficiency.

[0035] Furthermore, by setting the inner diameter of the second channel to be smaller than the inner diameter of the first channel and smaller than or equal to the outer diameter of the baffle, the baffle can be made to abut against the connection between the first and second channels or to fit against the inner wall of the second channel, thereby disconnecting the heating channel from the outlet and ensuring the uniformity of the heating channel temperature.

[0036] Furthermore, by gradually reducing the inner diameter of the second channel from the heating component to the cooling component, and by making its minimum inner diameter smaller than that of the baffle, the baffle can be made to fit against the inner wall of the second channel, thereby disconnecting the connection between the heating channel and the outlet and ensuring the temperature uniformity of the heating channel.

[0037] Furthermore, by extending and fixing the connecting shaft along the axial direction of the heating channel, the baffle can move between a first position and a second position along the axial direction of the connecting shaft, thereby disconnecting or connecting the outlet of the heating channel and the cooling component. Additionally, by extending the through hole on the bracket along the axial direction of the heating channel and movably inserting the connecting shaft with the baffle fixed into the through hole, the baffle can move between a first position and a second position along the axial direction of the through hole under the action of the connecting shaft, thereby disconnecting or connecting the outlet of the heating channel and the cooling component.

[0038] Furthermore, by arranging the connecting shaft radially within the heating channel and rotatably mounting the baffle on the connecting shaft, the baffle can rotate between a third and a fourth position. In the third position, the baffle adheres to the inner wall of the heating channel, disconnecting the heating channel from the outlet and ensuring temperature uniformity within the heating channel. In the fourth position, the angle between the baffle and the radial direction of the heating channel is greater than 0°, connecting the heating channel to the outlet of the cooling component. This allows the cooling airflow generated by the cooling component to rapidly cool the sample tube, improving cooling efficiency.

[0039] Furthermore, by installing a first insulation component over the heat-conducting block, the heat insulation performance of the heating component can be effectively enhanced, reducing the interference of the external environment on the heating process, thereby ensuring that the sample inside the sample tube is heated uniformly.

[0040] Furthermore, by setting a second insulation component on the side of the heat-conducting block away from the cooling component, and setting a third channel on the second insulation component that communicates with the heating channel, the interference of the external environment on the sample heating process can be reduced, and the sample tube can be installed and operated more easily.

[0041] Furthermore, by installing a heat insulation sheet in the third channel and setting at least one through-slit on the heat insulation sheet, the installation of the sample tube can be ensured, and the interference of the external environment on the sample heating process can be further reduced.

[0042] Furthermore, by setting a third insulation component between the heat-conducting block and the cooling component, and setting a fourth channel on the third insulation component that is connected to the heating channel, it is possible to ensure that the sample in the sample tube is heated evenly when the heating channel is disconnected from the outlet of the cooling component, and at the same time, when the heating channel is connected to the outlet of the cooling component, the cooling airflow generated by the cooling component can quickly cool the sample tube, thereby improving the cooling efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0054] Combination Figure 1-6 The heating furnace described in this application will be explained.

[0055] See Figure 1The heating furnace includes a protective cover 4, a temperature measuring element 14, a heating component 1, a cooling component, and a baffle assembly 3. The cooling component is a fan cooling component 2, and the heating component 1 is located on one side of the fan cooling component 2. The outlet of the fan cooling component 2 is located close to the heating component 1, and the inlet of the fan cooling component 2 is located away from the heating component 1. The protective cover 4 includes two connecting covers 41, which are detachably connected. The protective cover 4 formed by the two connecting covers 41 is fitted over the heating component 1 and the fan cooling component 2 as a whole, and serves a protective function.

[0056] It should be noted that a protective net can be installed at the inlet of the fan cooling component 2 to effectively prevent foreign objects from entering the fan cooling component 2 and ensure the safe and stable operation of the fan cooling component 2.

[0057] In the exemplary embodiments, the number of connecting covers 41 is not fixed and can be adjusted by those skilled in the art as needed. For example, the number of connecting covers 41 can be one, three, or other numbers. When there is only one connecting cover 41, it serves as a protective cover 4, which is directly fitted over the heating assembly 1 and the fan cooling assembly 2. When there are three or more connecting covers 41, adjacent connecting covers 41 are detachably connected. Furthermore, this application does not limit the detachable connection method of adjacent connecting covers 41, as long as it allows for the connection of adjacent connecting covers 41. For example, fasteners consisting of connecting pieces 42, bolts, and nuts can be used to connect adjacent connecting covers 41 together.

[0058] In the exemplary embodiments, the components protected by the protective cover 4 are not fixed and can be adjusted as needed by those skilled in the art. For example, the protective cover 4 may only be fitted over the heating component 1, or only over the cooling component.

[0059] In the exemplary embodiments, the specific type of cooling component is not fixed in this application, and those skilled in the art can adjust it according to the setting requirements. For example, the cooling component can also be an air compressor cooling component, which can also generate cooling airflow to cool the sample tube containing the sample.

[0060] See next Figure 1-6 The heating assembly 1 includes a heating element, a heat-conducting block 12, and a temperature-sensing element 14. The heat-conducting block 12 is disposed inside the connecting cover 41, and the temperature-sensing element 14 is disposed therein. The heating element is a heating wire 13, which is wound around the outside of the heat-conducting block 12. Four heating channels 121 are formed on the heat-conducting block 12, each extending in the same direction and penetrating the heat-conducting block 12. Each heating channel 121 is connected to the outlet of the cooling assembly. The four heating channels 121 can simultaneously heat four sample tubes containing samples, thereby improving experimental efficiency.

[0061] In the exemplary embodiments, the positions of the heating wire 13 and the temperature measuring element 14 are not fixed in this application, and those skilled in the art can adjust them as needed. For example, the heating wire 13 may also be disposed within the heat-conducting block 12, and / or the temperature measuring element 14 may be disposed within the heating channel 121. Furthermore, the specific arrangement of the heating element is not fixed in this application, and those skilled in the art can adjust it as needed. For example, the heating element may also be a heating rod, which may be disposed within the heat-conducting block 12.

[0062] In the exemplary embodiments, the number of heating channels 121 is not fixed and can be selected by those skilled in the art as needed. For example, the number of heating channels 121 can be 1, 2, 3 or other numbers.

[0063] See next Figure 3-4 The heating channel 121 includes a first channel 1211 and a second channel 1212 that are interconnected. The first channel 1211 is located away from the fan cooling assembly 2 and is a channel of equal diameter, allowing the bottom of the sample tube to be inserted into it. The second channel 1212 is located close to the fan cooling assembly 2 and is used to connect the first channel 1211 and the outlet of the cooling assembly. The second channel 1212 is funnel-shaped, and its inner diameter gradually decreases from the first channel 1211 toward the cooling assembly.

[0064] In the exemplary embodiments, the configuration of the second channel 1212 is not fixed and can be adjusted by those skilled in the art according to specific application scenarios. For example, the second channel 1212 can be a channel of equal diameter, with its inner diameter being smaller than that of the first channel 1211. Alternatively, the inner diameters of the first channel 1211 and the second channel 1212 can be the same.

[0065] See next Figure 3-4 In addition to component 6, the heating assembly 1 also includes a first insulating component 15, a second insulating component 16, and a third insulating component 17. The first insulating component 15 has a ring-shaped structure, is sleeved on the outside of the heat-conducting block 12, and covers the heating wire 13. This effectively enhances the heat insulation performance of the heating assembly 1, reduces interference from the external environment on the heating process, and ensures uniform heating of the sample inside the sample tube. The second insulating component 16 is located on the side of the heat-conducting block 12 away from the fan cooling assembly 2 and is connected to the end face of the first insulating component 15. The third insulating component 17 is located between the heat-conducting block 12 and the fan cooling assembly 2 and is connected to the end face of the first insulating component 15. This arrangement effectively prevents heat loss from the heat-conducting block 12 and the heating wire 13, and significantly improves the overall heat insulation performance of the heating furnace.

[0066] In exemplary embodiments, the inclusion of at least one of the first insulation member 15, the second insulation member 16, and the third insulation member 17 in this application is not mandatory, and those skilled in the art can select them as needed.

[0067] In an exemplary embodiment, a first support plate 11 can be provided on the side of the second insulation component 16 away from the fan cooling assembly 2, and the first support plate 11 is connected to the second insulation component 16. A connecting piece can be provided on the first support plate 11, and the position of the connecting piece corresponds to the connection point of two adjacent connecting covers 41. The connecting cover 41 is then connected to the connecting piece by bolts and nuts. This connection method not only realizes the connection of adjacent connecting covers 41, but also allows the protective cover 4 to be connected to the first support plate 11. It should be noted that the third channel 161 on the second insulation component 16 can penetrate the first support plate 11 to facilitate the installation of the sample tube.

[0068] In an exemplary embodiment, a second support plate 21 may also be provided on the fan cooling component 2. The second support plate 21 is provided on the side of the fan cooling component 2 close to the heating component 1, which facilitates the support of the heating component 1 and improves the overall stability of the heating furnace.

[0069] See next Figure 3-4 The second insulation component 16 has four third channels 161, which correspond one-to-one with the four first channels 1211 and are coaxially arranged. The inner diameter of the third channels 161 is the same as that of the first channels 1211, allowing the bottom of the sample tube to pass through the third channels 161 and extend into the heating channel 121. This effectively reduces interference from the external environment during the sample heating process and facilitates sample tube installation. The third insulation component 17 has four fourth channels 171, which correspond one-to-one with the four second channels 1212 and are coaxially arranged. The inner diameter of the fourth channels 171 is the same as the minimum inner diameter of the second channels 1212, and both are connected to the outlet of the fan cooling component 2. This allows the cooling airflow generated by the fan cooling component 2 to enter the heating channel 121 through the fourth channels 171 to rapidly cool the sample tube, improving cooling efficiency.

[0070] In an exemplary embodiment, the number of third channels 161 and fourth channels 171 needs to be adjusted according to the number of heating channels 121. For example, when there is one heating channel 121, there is also one third channel 161 and one fourth channel 171. When there are two heating channels 121, there are also two third channels 161 and two fourth channels 171.

[0071] See next Figure 1-3A heat insulation sheet 18, made of elastic material, is installed within the third channel 161. The heat insulation sheet 18 has through holes 181, giving it a ring-shaped structure. Eight radially arranged through slits 182 along the inner circumference of the heat insulation sheet 18 divide it into eight petal-like structures. When the sample tube passes through the through holes 181 into the heating channel 121, the petals are compressed and unfolded, thus adhering tightly to the outer wall of the sample tube to form effective heat insulation. This ensures the installation of the sample tube and further reduces interference from the external environment during the sample heating process. After the sample tube is removed, the elastic heat insulation sheet 18 automatically returns to its original shape.

[0072] In the exemplary embodiment, the number of penetration slits 182 is not fixed and can be adjusted by those skilled in the art as needed. For example, the number of penetration slits 182 can be 2, 3, or other numbers.

[0073] In the exemplary embodiments, the through hole 181 on the heat insulation sheet 18 is not mandatory, and those skilled in the art can adjust it according to the specific application scenario. For example, if the through hole 181 is not provided, a through slit 182 can be directly provided on the heat insulation sheet 18, which is also conducive to the installation of the sample tube and can further reduce the interference of the external environment on the sample heating process.

[0074] See next Figure 3-5A baffle assembly 3 is provided within the second channel 1212. The baffle assembly 3 includes a baffle 31, a connecting shaft 32, and a bracket 33. The bracket 33 is fixed to the inner wall of the second channel 1212. The connecting shaft 32 is fixed to the bracket 33 and extends along the bracket 33 toward the first channel 1211. A limit plate is provided at the end of the connecting shaft 32 away from the fan cooling assembly 2. The baffle 31 is located on the side of the bracket 33 away from the fan cooling assembly 2, and its inner diameter is larger than the minimum inner diameter of the second channel 1212 but smaller than the maximum inner diameter of the second channel 1212. The baffle 31 is provided with a connecting hole for the connecting shaft 32 to pass through, so that the baffle 31 is movably mounted on the connecting shaft 32, thereby being able to move along the connecting shaft 32 between a first position and a second position. In addition, the limit plate on the connecting shaft 32 effectively prevents the baffle 31 from falling off the connecting shaft 32 during movement. With the above configuration, when the heating component 1 heats the sample in the sample tube, the baffle 31 is in the first position, which is in contact with the inner wall of the second channel 1212, disconnecting the connection between the second channel 1212 and the fourth channel 171, thereby ensuring the heat insulation effect of the heating component 1. After the heating process is completed, the fan cooling component 2 operates, and the generated cooling airflow pushes the baffle 31 along the connecting shaft 32 to the second position, that is, to move away from the fan cooling component 2. At this time, the baffle 31 can be set near the first channel or the second channel, so that the baffle is no longer in contact with the inner wall of the second channel 1212, and the second channel 1212 and the fourth channel 171 form a connecting path, allowing the cooling airflow to enter the first channel 1211 through this path, thereby cooling the sample tube.

[0075] In the exemplary embodiments, the connection method between the bracket 33 and the connecting shaft 32 is not fixed, and those skilled in the art can adjust it according to the specific application scenario. For example, the bracket 33 is provided with a direction along the axial direction of the heating channel 121 (e.g., Figure 1-3 The connecting shaft 32 is movably inserted into the connecting hole (shown in the vertical direction as shown in Figure 6), and a baffle 31 is fixed thereon. To prevent the connecting shaft 32 from detaching from the channel, limit plates are provided at both ends of the connecting shaft 32. With this configuration, when the heating assembly 1 heats the sample in the sample tube, the baffle 31 is in the first position, fitting against the inner wall of the second channel 1212, disconnecting the connection between the second channel 1212 and the fourth channel 171. After the heating process is completed, the fan cooling assembly 2 operates, and the generated cooling airflow pushes the baffle 31, causing the connecting shaft 32 to move along the axial direction of the through hole 181 towards the second position, i.e., away from the fan cooling assembly 2. This also allows the second channel 1212 and the fourth channel 171 to form a connecting path, enabling the cooling airflow to enter the first channel 1211 through this path, thereby cooling the sample tube.

[0076] In the exemplary embodiments, the positional relationship between the baffle 31 and the bracket 33 is not fixed and can be adjusted as needed by those skilled in the art. For example, the bracket 33 can also be fixed to the inner wall of the first channel 1211. In this case, a connecting shaft 32 extending along the axial direction of the heating channel 121 can be fixed on the bracket 33, or a connecting hole extending along the axial direction of the heating channel 121 can be provided on the bracket 33, and the connecting shaft 32 can be movably inserted into the connecting hole. When the connecting shaft 32 is fixed on the bracket 33, the connecting shaft 32 extends along the bracket 33 toward the fan cooling component 2, and the baffle 31 is located on the side of the bracket 33 near the fan cooling component 2 and is movably disposed on the connecting shaft 32. When the connecting shaft 32 is movably disposed on the bracket 33, the connecting hole on the bracket 33 extends along the axial direction of the heating channel 121, and the baffle 31 is disposed on the connecting shaft 32 on the side of the bracket 33 near the fan cooling component 2.

[0077] In an exemplary embodiment, when the second channel 1212 is a channel of equal diameter and its inner diameter is smaller than that of the first channel 1211, the baffle 31 can not only disconnect the connection between the second channel 1212 and the fourth channel 171 by fitting against the second channel 1212, but also abut against the connection between the first channel 1211 and the second channel 1212 to disconnect the connection between the second channel 1212 and the fourth channel 171; when the baffle 31 is located inside the first channel 1211, the connection between the second channel 1212 and the fourth channel 171 is maintained. However, it should be noted that when the connection between the second channel 1212 and the fourth channel 171 is disconnected by abutting against the connection between the first channel 1211 and the second channel 1212, the outer diameter of the baffle 31 is larger than the outer diameter of the baffle 31 when the connection between the second channel 1212 and the fourth channel 171 is disconnected by fitting against the second channel 1212.

[0078] In the exemplary embodiment, the bracket 33 is not mandatory, and those skilled in the art can choose to install it according to their needs. When the bracket 33 is not installed, and the inner diameter of the second channel 1212 gradually decreases from the heating component 1 towards the cooling component, the connecting shaft 32 can be fixed to the inner wall of the second channel 1212 and extend in the direction of the first channel 1211. When the bracket 33 is not installed, and the second channel 1212 is a channel of equal diameter, and its inner diameter is smaller than the inner diameter of the first channel 1211 and smaller than the outer diameter of the baffle 31, the connecting shaft 32 is fixed at the connection between the first channel 1211 and the second channel 1212 and extends in the direction of the first channel 1211.

[0079] In the exemplary embodiments, the specific configuration of the baffle assembly 3 is not fixed and can be adjusted as needed by those skilled in the art. For example, the baffle assembly 3 includes a baffle 31 and a connecting shaft 32. The connecting shaft 32 is located near the cooling component in the heating channel 121 and extends radially along the heating channel 121. The baffle 31 is rotatably mounted on the connecting shaft 32 and can rotate between a third position and a fourth position. When the baffle 31 is in the third position, it fits against the inner wall of the heating channel 121. When the baffle 31 is in the fourth position, the angle between the baffle 31 and the heating channel 121 in the radial direction is greater than 0°, allowing the second channel to communicate with the fourth channel. In this structure of the baffle assembly 3, the second channel 1212 in the heating channel 121 is a channel of equal diameter, with an inner diameter smaller than that of the first channel 1211, or the inner diameters of the first channel 1211 and the second channel 1212 can be the same. The connecting shaft 32 can be located in either the first channel 1211 or the second channel 1212. With the above configuration, when the heating assembly 1 heats the sample in the sample tube and the baffle 31 is in the third position, the baffle 31 is in contact with the inner wall of the first channel 1211 or the second channel 1212, disconnecting the connection between the heating channel 121 and the fourth channel 171. After the heating process is completed, the fan cooling assembly 2 operates, and the generated airflow pushes the baffle 31 to rotate around the connecting shaft 32, causing the baffle 31 to rotate from the third position to the fourth position. At this time, the baffle 31 forms a certain angle with the heating channel 121 in the radial direction, and the heating channel 121 is connected to the fourth channel 171, allowing the cooling airflow to enter the first channel 1211 through this path, thereby cooling the sample tube.

[0080] Combination Figure 1-6 This describes the working process of the heating furnace in this application.

[0081] When it is necessary to heat the sample in the sample tube, the sample tube containing the sample is inserted into the heating channel 121 through the heat insulation sheet 18. At this time, the baffle 31 is in the first position, in contact with the inner wall of the second channel 1212, and the second channel 1212 and the fourth channel 171 are not connected to each other. This heating channel 121 can ensure that the heat is concentrated during the heating process and provide a stable heating environment for the sample.

[0082] After the heating process is completed, the fan cooling component 2 will operate, and the generated cooling airflow will push the baffle 31 to move along the connecting shaft 32 to the second position, that is, move away from the fan cooling component 2, so that the baffle 31 is no longer in contact with the inner wall of the second channel 1212, and the second channel 1212 and the fourth channel 171 form a connecting path, so that the cooling airflow can enter the first channel 1211 through this path, thereby cooling the sample tube.

[0083] After the sample tube cools down, it can be removed from the heating channel 121 and then transferred to the adsorption testing device for subsequent analysis and testing.

[0084] In addition, this application also provides an adsorption apparatus, which includes the heating furnace described in any of the above embodiments.
