Description

Technical Field

[0001] This utility model relates to the field of oscillator technology, and specifically to an automatic oscillation device. Background Technology

[0002] Specific surface area is one of the important parameters characterizing the physical properties of solid materials, and it is widely used in the performance evaluation of catalysts, adsorbents, battery materials, and porous materials. To ensure the accuracy of specific surface area test data, sample pretreatment is necessary to remove moisture and impurities and ensure the consistency of sample state. Among these pretreatment steps, the sample loading process is a key step and has a significant impact on the stability and repeatability of the test results.

[0003] Currently, U-shaped glass tubes are commonly used as sample containers in the sample pretreatment process for specific surface area testing. Operators first number, weigh, and record the mass of the dried U-shaped glass tubes. Then, they use weighing paper to weigh an appropriate amount of sample and transfer it into the U-shaped tube through a funnel. Because some sample particles are fine or have a certain degree of adhesion, manual filling can easily lead to problems such as sample adhesion to the tube wall or funnel inner wall, insufficient filling, or uneven filling, thus affecting the reliability of subsequent tests. Utility Model Content

[0004] This invention provides an automatic oscillation device to solve the problem in the prior art where samples tend to adhere to the tube wall or the inner wall of the funnel during the transfer of samples to the U-tube, resulting in insufficient or uneven filling.

[0005] This utility model provides an automatic oscillation device for pretreatment of samples for specific surface area testing, comprising: a housing, wherein a support plate and a mounting assembly are arranged sequentially from bottom to top inside the housing, and a vibration cavity is formed between the support plate and the mounting assembly; the mounting assembly is provided with a mounting hole, through which a U-shaped tube can be inserted, and the bottom of the U-shaped tube extends into the vibration cavity; the bottom of the support plate is provided with a vibration structure, which is adapted to drive the U-shaped tube to vibrate.

[0006] According to some embodiments of the present invention, the top of the tray is provided with a buffer, and the bottom of the U-shaped tube abuts against the buffer.

[0007] According to some embodiments of this utility model, the buffer is a rubber pad or a silicone pad.

[0008] According to some embodiments of the present invention, a placement cavity is formed between the tray and the bottom of the housing, the vibration structure is located in the placement cavity and is fixedly installed on the bottom of the tray, and the vibration structure drives the tray to vibrate, thereby causing the U-shaped tube to vibrate.

[0009] According to some embodiments of this utility model, the vibration structure is a turbine-type pneumatic vibrator or a slider-type pneumatic vibrator.

[0010] According to some embodiments of the present invention, the automatic oscillation device further includes a monitoring component and a controller. The monitoring component and the vibration structure are both communicatively connected to the controller. The monitoring component is disposed on the side wall of the housing to detect the feeding parameters of the funnel inside the U-shaped tube and feed them back to the controller in real time. The controller is adapted to accept the feeding parameters to control the start and stop of the vibration structure.

[0011] According to some embodiments of the present invention, the mounting assembly includes a first mounting partition and a second mounting partition. The first mounting partition and the second mounting partition are spaced apart within the housing and located above the support plate. The first mounting partition has a first mounting hole, and the second mounting partition has a second mounting hole. The first mounting hole and the second mounting hole are coaxially arranged, and the U-shaped tube passes through the first mounting hole and the second mounting hole from top to bottom.

[0012] According to some embodiments of the present invention, a first buffer ring is provided on the wall of the first mounting hole, and a second buffer ring is provided on the wall of the second mounting hole, and the sidewalls of the U-shaped tube abut against the first buffer ring and the second buffer ring.

[0014] According to some embodiments of the present invention, the mounting assembly further includes a spacer plate disposed on the first mounting partition plate and between two adjacent mounting holes.

[0015] Beneficial effects: The automatic oscillation device provided by this utility model, by having a support plate and mounting components inside the housing, forming a vibration chamber therebetween, and in conjunction with a vibration structure at the bottom of the support plate, allows the U-shaped tube installed in the mounting hole to vibrate within the vibration chamber. This effectively prevents the sample from adhering to the inner wall of the U-shaped tube or funnel during transfer, thereby improving the uniformity and completeness of sample loading in the U-shaped tube. The vibration structure drives the U-shaped tube to oscillate automatically, allowing the sample to enter the U-shaped tube more completely, eliminating the need for manual tapping or auxiliary loading, reducing the impact of human factors on the consistency of sample processing, and improving the automation level and efficiency of pre-experimental processing. Furthermore, this automatic oscillation device avoids sample loss caused by sample adhesion or residue on the inner wall of the U-shaped tube or funnel, contributing to improved test repeatability and data accuracy.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1 As shown, this utility model provides an automatic oscillation device for pretreatment of samples for specific surface area testing, including: a shell 1, in which a support plate 3 and a mounting assembly 2 are arranged sequentially from bottom to top, and a vibration cavity is formed between the support plate 3 and the mounting assembly 2; the mounting assembly 2 is provided with a mounting hole, through which a U-shaped tube can be inserted, and the bottom extends into the vibration cavity; the bottom of the support plate 3 is provided with a vibration structure 5, which is adapted to drive the U-shaped tube to vibrate.

[0021] Specifically, by providing a support plate 3 and mounting assembly 2 within the housing 1, forming a vibration chamber therebetween, and cooperating with the vibration structure 5 located at the bottom of the support plate 3, the U-shaped tube installed in the mounting hole can vibrate within the vibration chamber. This effectively prevents the sample from adhering to the inner wall of the U-shaped tube or funnel during transfer, thereby improving the uniformity and completeness of sample loading in the U-shaped tube. The vibration structure 5 drives the U-shaped tube to oscillate automatically, allowing the sample to enter the U-shaped tube more completely, eliminating the need for manual tapping or auxiliary loading, reducing the impact of human factors on the consistency of sample processing, and improving the automation level and efficiency of pre-experimental processing. This automatic oscillation device avoids sample loss caused by adhesion or residue, helping to improve the repeatability of tests and the accuracy of data.

[0022] Understandably, this automatic oscillation device features a compact structure, with the vibration chamber and mounting assembly 2 integrated within the housing 1. It is suitable for sample pretreatment steps in various existing specific surface area testing systems, demonstrating good versatility and adaptability. Through a rational structural design and the coordination of the vibration mechanism, it solves the problems of low sample transfer efficiency and uneven loading, exhibiting significant practical value and promising prospects for wider application.

[0023] In some embodiments of this utility model, the top of the tray 3 is provided with a buffer 4, and the bottom of the U-shaped tube abuts against the buffer 4.

[0024] In some embodiments of this utility model, the buffer 4 is a rubber pad or a silicone pad.

[0025] Specifically, the buffer 4, as a flexible contact structure, effectively mitigates the mechanical impact generated when the vibrating structure 5 drives the U-shaped tube, preventing the bottom of the U-shaped tube from cracking, wearing, or displacing due to rigid contact during repeated oscillations, thus improving the service life and reliability of the device. While reducing impact, the buffer 4 also provides a certain degree of support, ensuring the U-shaped tube maintains a stable stress state during vibration, preventing a decrease in vibration efficiency due to loosening or shaking, thereby enhancing the vibration transmission effect during sample loading.

[0026] Understandably, the buffer 4 can be designed to fit the shape of the U-tube, improving the fit accuracy between the U-tube and the support plate 3, facilitating installation and disassembly, and improving the overall maintainability of the device.

[0027] Buffer 4 is made of rubber or silicone pads. Both rubber and silicone pads have good elasticity and flexibility, which can effectively absorb and disperse mechanical stress during the vibration of the U-shaped tube, further reducing the impact force of vibration on the bottom of the glass or brittle U-shaped tube, preventing damage, and improving the safety performance of the device. In addition, rubber or silicone pads have good chemical corrosion resistance and temperature resistance, and can adapt to various complex environments in the specific surface area test sample processing, such as solvent residue, high temperature or low temperature treatment, etc., ensuring the long-term stable operation of buffer 4.

[0028] By using rubber or silicone pads as the cushioning material, good cushioning performance is ensured while also improving the environmental adaptability and maintainability of the structure, further optimizing the overall use effect and practical value of this utility model.

[0029] In some embodiments of this utility model, a placement cavity is formed between the tray 3 and the bottom of the housing 1. The vibration structure 5 is located in the placement cavity and is fixedly installed on the bottom of the tray 3. The vibration structure 5 drives the tray 3 to vibrate, thereby causing the U-shaped tube to vibrate.

[0030] Specifically, by forming a placement cavity between the tray 3 and the bottom of the housing 1, and setting the vibration structure 5 in the placement cavity and fixing it to the bottom of the tray 3, the vibration structure 5 can directly drive the tray 3 to vibrate, thereby driving the U-shaped tube to vibrate. The vibration structure 5 is integrated into the placement cavity formed between the tray 3 and the housing 1, making full use of the internal space of the housing 1, avoiding exposure or occupying additional installation space, making the overall device structure more compact and beautiful, and facilitating equipment integration and batch deployment.

[0031] It is understandable that the vibration structure 5 is fixed to the bottom of the support plate 3 and can directly drive the support plate 3 to generate vibration. Compared with the method of transmitting vibration through indirect components, it has higher energy utilization and vibration response efficiency, which is conducive to forming a stable and uniform oscillation state, thereby improving the looseness and distribution uniformity of the sample in the U-shaped tube.

[0032] Furthermore, encapsulating the vibration structure 5 within the placement cavity helps isolate the vibration source from other parts of the housing 1 or the external environment, reducing mechanical noise or interference generated during vibration and improving the operating environment. The placement cavity provides dedicated installation space for the vibration structure 5, facilitating the installation, positioning, and subsequent maintenance of the vibration device, thus improving maintainability and assembly efficiency.

[0033] In some embodiments of this utility model, the vibration structure 5 is a turbine-type pneumatic vibrator or a slider-type pneumatic vibrator.

[0034] Specifically, both turbine-type and slider-type pneumatic vibrators can adjust the vibration frequency and amplitude by regulating the air supply pressure. They possess strong vibration force output and can flexibly adjust the oscillation intensity according to samples with different particle sizes or densities, improving the applicability and reliability of sample loading. Compared to electric vibrators, pneumatic vibrators are driven by compressed air, avoiding electrical sparks or heat generation. They are particularly suitable for sample processing environments requiring explosion protection or high cleanliness, such as chemical laboratories or powder material laboratories, improving the overall safety of the device.

[0035] In some embodiments of this utility model, the automatic oscillation device further includes a monitoring component and a controller. Both the monitoring component and the vibration structure 5 are communicatively connected to the controller. The monitoring component is located on the side wall of the housing 1 to detect the feeding parameters of the funnel inside the U-shaped tube and feed them back to the controller in real time. The controller is adapted to receive the feeding parameters to control the start and stop of the vibration structure 5.

[0036] Specifically, by incorporating a monitoring component and a controller into the automatic oscillation device, and ensuring that both the monitoring component and the vibrating structure 5 are communicatively connected to the controller, the system can automatically control the start and stop of the vibrating structure 5 based on real-time detection data. The monitoring component can collect real-time feeding parameters of the funnel inside the U-shaped tube, such as feeding speed and particle accumulation status, and feed this data back to the controller. The controller then determines whether to start or stop the vibrating structure 5 based on preset logic, achieving automatic response without manual intervention, thus improving the device's intelligence and efficiency. Through dynamic monitoring of the feeding status, the vibrating structure 5 can be shut down promptly when the sample has been fully fed or reached the target filling state, avoiding sample disturbance, overfilling, or unnecessary wear on the equipment caused by continuous vibration, thereby improving the device's reliability and service life.

[0037] Understandably, by dynamically monitoring the feeding status, the vibration structure 5 can be shut off in a timely manner when the sample has been fully fed or reached the target filling state, avoiding sample disturbance, overfilling, or unnecessary wear on the equipment caused by continuous vibration, thus improving the reliability and service life of the device. The controller can record operating parameters and detect anomalies based on monitoring data. Once situations such as material blockage, empty material, or abnormal vibration occur, an alarm or protection mechanism can be implemented to further ensure the safety of equipment operation.

[0038] In some embodiments of this utility model, the mounting component 2 includes a first mounting partition 21 and a second mounting partition 22. The first mounting partition 21 and the second mounting partition 22 are spaced apart inside the housing 1 and located above the support plate 3. The first mounting partition 21 is provided with a first mounting hole 211, and the second mounting partition 22 is provided with a second mounting hole 221. The first mounting hole 211 and the second mounting hole 221 are coaxially arranged, and the U-shaped tube passes through the first mounting hole 211 and the second mounting hole 221 from top to bottom.

[0039] Specifically, by setting coaxial mounting holes on the two mounting partitions, the U-shaped tube forms a two-point positioning structure in the vertical direction, effectively preventing it from shifting, swaying, or tilting during vibration, ensuring it maintains a stable working posture, and improving oscillation efficiency and sample loading consistency. The first mounting partition 21 and the second mounting partition 22 jointly undertake the functions of installing and limiting the U-shaped tube, dispersing the forces it experiences during vibration. Compared with the single-point mounting assembly 2, it has stronger stability and load-bearing capacity, and is suitable for installing long or thin-walled U-shaped tubes, preventing structural stress concentration that could lead to damage.

[0040] Understandably, the coaxially arranged first mounting hole 211 and second mounting hole 221 facilitate the rapid insertion and precise alignment of the U-tube, reducing the difficulty of manual operation, improving assembly efficiency, and making it suitable for rapid batch replacement operations in experimental environments. The mounting component 2 can be customized according to parameters such as the diameter and length of the U-tube, facilitating the replacement of different models of U-tubes, achieving structural modularity and standardization, and enhancing the versatility and expandability of the device.

[0041] In some embodiments of this utility model, a first buffer ring is provided on the wall of the first mounting hole 211, and a second buffer ring is provided on the wall of the second mounting hole 221. The sidewalls of the U-shaped tube abut against the first buffer ring and the second buffer ring.

[0042] Specifically, a first buffer ring and a second buffer ring are respectively provided on the walls of the first mounting hole 211 and the second mounting hole 221, and the side wall of the U-shaped tube abuts against both buffer rings; the buffer ring, as a flexible contact component, can provide elastic support for the U-shaped tube during vibration, absorb the relative motion energy between it and the wall of the mounting hole, and prevent damage or cracking of the U-shaped tube wall due to violent shaking or resonance. It is suitable for U-shaped tubes made of glass or with thin walls.

[0043] Understandably, the inclusion of buffer rings in both mounting holes allows for flexible clamping and limiting of the U-tube at both the upper and lower positions. This not only avoids the risk of breakage associated with rigid clamping but also ensures that the U-tube maintains its vibration freedom while possessing good structural stability, thereby improving the accuracy and efficiency of the oscillation process. The buffer rings form a vibration isolation medium between the U-tube and the shell structure 1, effectively isolating the transmission of vibration energy to the upper structure, reducing structural noise and mechanical interference during overall equipment operation, and contributing to a more stable experimental environment.

[0044] In some embodiments of this utility model, the mounting component 2 is provided with a plurality of mounting holes, which are arranged in an array.

[0045] Specifically, by arranging multiple arrayed mounting holes on mounting component 2, multiple U-shaped tubes can be installed simultaneously, enabling parallel operation of multiple tubes on one machine. This meets the need for simultaneous processing of multiple sets of samples, significantly improving work efficiency and experimental throughput, and is particularly suitable for pretreatment scenarios for large-scale specific surface area testing.

[0046] In some embodiments of the present invention, the mounting assembly 2 further includes a spacer 23, which is disposed on the first mounting partition 21 and between two adjacent mounting holes.

[0047] Specifically, the spacer plate 23, acting as a physical partition structure, is installed between adjacent mounting holes. It effectively prevents multiple U-shaped tubes from colliding with each other due to lateral swaying during vibration, avoiding test tube damage or sample contamination, and ensuring the safety and independence of the multi-station oscillation process. The spacer plate 23 creates a clear separation space between multiple U-shaped tubes, ensuring consistent spacing during installation, preventing skewing or tipping, improving the overall structural alignment and visual clarity, and facilitating operation and inspection.

[0048] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
