Description

Technical Field

[0001] This utility model relates to the field of chemical experimental equipment technology, and in particular to a laboratory glass reaction vessel that facilitates sampling at any time. Background Technology

[0002] In laboratory research in fields such as chemistry, pharmaceuticals, and materials science, single-layer glass reactors are widely used in experimental processes such as organic synthesis, catalytic reactions, and substance preparation due to their excellent chemical stability, transparency, and ease of operation. However, existing single-layer glass reactors have significant drawbacks in sampling operations during the reaction process: traditional designs typically lack dedicated sampling ports, forcing researchers to retrieve samples for analysis only after the reaction is complete by opening the glass lid or discharge port. This method cannot meet the need for real-time monitoring during the reaction, limiting researchers' dynamic control over the reaction process and affecting the accuracy and timeliness of experimental results. Furthermore, frequent opening of the reactor lid for sampling is not only cumbersome but may also compromise the airtightness of the reaction environment, increasing the risk of sample contamination, liquid splashing, and operator exposure to hazardous substances.

[0022] Example

[0023] Reference Figures 1-3 This utility model provides a laboratory glass reaction vessel that facilitates sampling at any time. It belongs to the field of chemical experimental equipment technology and aims to solve the technical problem that traditional single-layer glass reaction vessels lack a dedicated sampling device and cannot sample in real time during the reaction process.

[0024] Its main structure includes a fixed platform 1, made of high-strength, corrosion-resistant material, which serves as the supporting foundation for the entire device, ensuring stable operation of the reactor on a laboratory workbench and suitable for experimental needs in fields such as chemistry, pharmaceuticals, and materials science. A glass reaction chamber 2 is fixedly installed at the center of the top of the fixed platform 1. The glass reaction chamber 2 is made of borosilicate glass with high transparency, high temperature resistance, and chemical corrosion resistance. It has an internal reaction chamber 4 to contain the reaction raw materials and products. Its transparent design allows researchers to observe the reaction process in real time, ensuring experimental controllability. A glass cover 3, also made of borosilicate glass, is positioned directly above the glass reaction chamber 2. Together with the glass reaction chamber 2, it forms a sealed reaction environment, preventing the leakage of volatile substances or the entry of external impurities, thus ensuring the purity of the reaction environment.

[0025] A first connecting ring 14 is fitted onto the outer surface of the top of the glass reaction chamber 2, and a second connecting ring 15 is fitted onto the outer surface of the bottom of the glass cover 3. The first connecting ring 14 and the second connecting ring 15 are fixedly connected by bolts to form a robust sealing structure, which is also easy to disassemble for cleaning or maintenance, ensuring the long-term reliability of the device. The front and rear ends of the first connecting ring 14 are fixedly connected to fixed columns 17 via connecting rods 16. The fixed columns 17 provide additional structural support for the device, enhancing overall stability. A support base 18 is fixedly connected to the front side of the top of the rear fixed column 17, supporting the rotary motor 5. The rotary motor 5 is movably mounted above the support base 18, and its output end is driven by a rotating shaft 6 via a coupling. The bottom end of the rotating shaft 6 extends into the reaction chamber 4, where a stirring blade 7 is fixedly connected. The rotary motor 5 drives the rotating shaft 6 to rotate, causing the stirring blade 7 to uniformly stir the raw materials within the reaction chamber 4, promoting thorough mixing of the reactants, improving reaction efficiency and product consistency, making it particularly suitable for experimental scenarios requiring uniform reaction.

[0026] To meet the diverse needs of laboratory operations, an exhaust pipe 19 is installed on the left side of the top of the glass reaction chamber 2. The exhaust pipe 19 is used to discharge volatile gases generated during the reaction or to regulate the pressure within the reaction chamber 4, ensuring a safe and stable reaction process. A feed inlet 20 is located on the front side of the top of the glass reaction chamber 2. The feed inlet 20 allows personnel to easily add raw materials or reagents into the reaction chamber 4. It is equipped with a sealing cap to maintain the airtightness of the reaction environment, making operation simple and efficient. A discharge pipe 8 is fixedly connected to the center of the bottom of the reaction chamber 4. The discharge pipe 8 is made of corrosion-resistant material and is used to discharge the reaction products. A solenoid valve 21 is installed at its bottom. The solenoid valve 21 precisely regulates the opening and closing state of the discharge pipe via electrical control, facilitating control of the timing and flow rate of product discharge, improving the automation and safety of the operation.

[0027] The core innovation of this device lies in the sampling channel 9 located on the left side of the bottom of the reaction chamber 4. A sampling port 10 is located directly below the sampling channel 9, and a sampling bottle 11 is threadedly connected to the bottom of the sampling port 10. The sampling bottle 11 is made of transparent glass, allowing researchers to easily observe the sample collection process and ensure accurate sampling. The output end of the sampling channel 9 is connected to a guide channel 12, which in turn connects to the interior of the discharge pipe 8, creating a flexible path for material flow. A sealing assembly 13 is located inside the guide channel 12 and diagonally above the sampling port 10. The sealing assembly 13 includes a sealing plate 13a slidably connected to the bottom wall of the guide channel 12. A sealing plug 13b is located at the bottom left side of the sealing plate 13a, precisely sealing the sampling port 10 to prevent uncontrolled flow of material from the reaction chamber 4 into the sampling bottle 11. A connecting shaft 13c is rotatably connected to the inside of the right side of the sealing plate 13a. A threaded rod 13d is fixedly connected to the bottom end of the connecting shaft 13c. The bottom end of the threaded rod 13d passes through the inner wall of the flow channel 12 and extends to its outside. A knob 13e is fixedly connected to the threaded rod 13d, which is convenient for manual operation by the experimenter to control the opening and closing of the sealing assembly. The threaded rod 13d is threadedly connected to the bottom wall of the flow channel 12. A limiting disk 13f is fixedly connected to the top end of the connecting shaft 13c. The limiting disk 13f is rotatably connected to the upper surface of the sealing plate 13a. Together with the connecting shaft 13c, the sealing plate 13a is clamped between the limiting disk 13f and the threaded rod 13d, ensuring that the rotation of the threaded rod 13d does not drive the sealing plate 13a to rotate, but instead pushes it to slide along the flow channel 12.

[0028] The threaded rod 13d is rotatably connected to the sealing plate 13a via the connecting shaft 13c. Combined with the clamping action of the limiting plate 13f, this ensures that the normal rotation of the threaded rod 13d is not affected, while also stably driving the movement of the sealing plate 13a. When the experimenter needs to take a sample, rotating the knob 13e causes the threaded rod 13d to rotate and move upward inside the guide channel 12. The threaded rod 13d pushes the sealing plate 13a to slide obliquely upward via the connecting shaft 13c, and the sealing plate 13a causes the sealing plug 13b to move away from the sampling port 10. When the upper surface of the sealing plate 13a abuts against the inner top wall of the guide channel 12, an opening is formed below the sealing plate 13a, and the sealing plug 13b is completely removed from the sampling port 10. The raw material in the reaction chamber 4 flows into the sampling bottle 11 through the sampling channel 9 and the sampling port 10. The transparent glass material of the sampling bottle 11 allows for easy observation of whether it is full. Once full, the experimenter rotates the knob 13e in the opposite direction, causing the threaded rod 13d to rotate downwards, resealing the sampling port 10 with the sealing plate 13a and the sealing plug 13b, restoring the airtight state. The experimenter can then safely remove the sampling bottle 11 for analysis. This design allows for sampling at any time during the reaction without opening the glass cap 3, significantly reducing sample contamination, liquid splashing, and operational risks. It also adapts to changes in liquid level, meeting the real-time monitoring needs of the laboratory. After sampling, the reaction product can be discharged through the discharge pipe 8 by opening the solenoid valve 21. The entire process is simple, safe, and efficient, making it particularly suitable for chemical synthesis and substance separation experiments.
