Description

Technical Field

[0001] This utility model belongs to the technical field of material retrieval tables, specifically relating to a multifunctional laboratory material retrieval table. Background Technology

[0002] In fields such as pathology diagnosis, the sampling table is one of the most important safety devices in a laboratory. It provides researchers with a relatively clean operating environment, facilitating the extraction of cells and tissues from samples for specimen preparation. However, existing sampling tables still have some problems that urgently need to be addressed.

[0003] In traditional tissue sampling stations, samples are typically preserved by immersing them in formalin. Formalin is a highly irritating and toxic gas that is easily soluble in water and poses serious health risks. Long-term exposure to low doses of formalin can cause chronic respiratory diseases and other ailments, while high concentrations can be toxic to the nervous system. To eliminate these toxic gases, traditionally, a toxic gas extraction system was installed on the sampling station to draw the gases directly from the work surface into the exhaust pipes and release them outdoors. However, this process causes significant air pollution.

[0004] A multifunctional laboratory sampling table, with announcement number CN212524184U, uses an exhaust fan mounted on the table body to draw toxic gases into a purification tank. The purification tank contains a detachable layer of diatomaceous earth, a molecular sieve, and an activated carbon, arranged from bottom to top. After passing through multiple layers of adsorption, the gas is discharged through an exhaust pipe, effectively preventing toxic gas pollution to the environment and reducing the health risks to operators.

[0005] The aforementioned technical solution suffers from inconvenience in replacing the adsorption filter element during practical use. Although a flange cover is installed on the side wall of the purification tank, the filter element must be removed for replacement, making the operation cumbersome. Furthermore, the gas flow path between different adsorption layers may be altered during replacement, affecting subsequent adsorption efficiency. In addition, frequent disassembly of the flange cover may lead to a decrease in its sealing performance, thereby affecting the overall sealing and adsorption efficiency of the purification device, failing to meet the requirements for long-term stable operation. Therefore, there is an urgent need for a multifunctional laboratory material handling station that facilitates filter element replacement while ensuring good sealing and stable adsorption performance, further improving the safety, convenience, and environmental friendliness of experimental operations.

[0022] Please see Figure 3 and Figure 4 As shown, the sealed box 8 is equipped with a quick-change mechanism 9. The quick-change mechanism 9 specifically includes a U-shaped frame 910 slidably connected to the inner wall of the sealed box 8. A placement frame 911 is installed on the inner wall of the U-shaped frame 910. A diatomaceous earth adsorption filter element 912, a molecular sieve adsorption filter element 913, and an activated carbon adsorption filter element 914 are placed on the placement frame 911. A sealing base plate 908 is fixedly connected to the bottom surface of the U-shaped frame 910. A connecting rod 907 is installed on the bottom surface of the sealing base plate 908. A connecting plate 906 is fixedly connected to the bottom end of the connecting rod 907. A round rod 905 is fixedly connected to the upper surface of the connecting plate 906. A sliding plate 904 is installed at the top of the 905. A strip-shaped square tube 901 is slidably connected to the outer surface of the sliding plate 904. The strip-shaped square tube 901 is fixedly connected to the back of the sealing box 8. A motor 902 is installed on the top surface of the strip-shaped square tube 901. A lead screw 903 is installed at the output end of the motor 902. The lead screw 903 is rotatably connected to the inside of the strip-shaped square tube 901. The lead screw 903 is threadedly connected to the inside of the sliding plate 904. A sealing ring 909 is installed on the upper surface of the sealing base plate 908. When the sealing ring 909 moves upward into place, it will contact the bottom surface of the sealing box 8 to seal the sealing box 8. In this embodiment, the quick-change mechanism 9 on the sealing box 8 is the core component. Its U-shaped frame 910, placement frame 911, diatomaceous earth adsorption filter element 912, molecular sieve adsorption filter element 913, and activated carbon adsorption filter element 914 achieve toxic gas purification. Moreover, the transmission structure composed of the motor 902, lead screw 903, and other components facilitates filter element replacement.

[0023] In implementation, first, the cabinet 1 is placed stably in a suitable position in the laboratory using support legs 14. The workbench 2 is fixedly installed on the upper surface of the cabinet 1, and the upright plate 5 is vertically fixed to one side of the back of the workbench 2. The exhaust fan 6 is installed on the front of the upright plate 5, and the air inlet pipe 7 is connected so that one end is connected to the exhaust fan 6 and the other end is connected to the sealing box 8. A quick-change mechanism 9 is installed inside the sealing box 8, and the U-shaped frame 910 is slidably set on the inner wall of the sealing box 8. Diatomaceous earth adsorption filter element 912, molecular sieve adsorption filter element 913, and activated carbon adsorption filter element 914 are placed sequentially on the frame 911 inside the U-shaped frame 910, and the sealing base plate 908 and sealing ring 909 are installed. The strip-shaped square tube 901 is fixed to the back of the sealing box 8, and the motor 902 and lead screw 903 are installed. The sliding plate 904, round rod 905, connecting plate 906, and connecting rod 907 are connected so that the U-shaped frame 910 can be raised and lowered in a controlled manner. Finally, install the top plate 10, and install the lighting lamp 11 and ultraviolet disinfection lamp 12 on its bottom surface. Connect the exhaust pipe 13 to the sealed box 8. In use, turn on the exhaust fan 6 to extract toxic gases, which are then purified through the filter. To replace the filter, simply start the motor 902.

[0024] During pathological diagnosis and other experimental procedures, researchers collect tissue samples immersed in formalin on workbench 2. Toxic gases generated during this process are drawn into the sealed container 8 through the air inlet pipe 7 by the exhaust fan 6. The exhaust fan 6, installed on the front of the upright plate 5, draws the toxic gases through the air inlet pipe 7 to the sealed container 8. The quick-change mechanism 9 on the sealed container 8 plays a crucial role here. In the quick-change mechanism 9, a U-shaped frame 910 is slidably connected to the inner wall of the sealed container 8. A placement frame 911 installed on the inner wall of the U-shaped frame 910 holds a diatomaceous earth adsorption filter element 912, a molecular sieve adsorption filter element 913, and an activated carbon adsorption filter element 914, used to adsorb and purify the toxic gases entering the sealed container 8.

[0025] When the adsorption filter element needs to be replaced, the motor 902 is started. The motor 902 is installed on the top surface of the strip-shaped square tube 901. The lead screw 903 at its output end is rotatably connected to the inside of the strip-shaped square tube 901 and threadedly connected to the inside of the slide plate 904. The motor 902 drives the lead screw 903 to rotate, causing the slide plate 904 to slide downward along the strip-shaped square tube 901. The slide plate 904 drives the U-shaped frame 910 and the sealing base plate 908 to move downward through the round rod 905, connecting plate 906 and connecting rod 907, thereby removing the placement frame 911 and the adsorption filter element from the sealed box 8, making filter element replacement convenient and quick.

[0026] After replacement, start motor 902 again to make lead screw 903 rotate in the opposite direction, driving U-shaped frame 910 to move upward. The sealing ring 909 on the upper surface of sealing base plate 908 moves upward accordingly. When sealing ring 909 contacts the bottom surface of sealing box 8, it seals the sealing box 8, ensuring that gas can only be purified through adsorption filter element, preventing leakage and ensuring adsorption effect.

[0027] The gas, after being purified by multiple layers of adsorption by the diatomaceous earth adsorption filter element 912, the molecular sieve adsorption filter element 913, and the activated carbon adsorption filter element 914, is discharged through the exhaust pipe 13 fixedly connected to the back of the sealed box 8.

[0028] In addition, the faucet 4 installed on the workbench 2 can be used for cleaning, and the sink 3 is used to collect wastewater; the two lights 11 installed on the bottom of the top plate 10 on the upper surface of the upright plate 5 provide sufficient lighting for experimental operations; the ultraviolet disinfection lamp 12 installed on the bottom of the top plate 10 can disinfect the workbench surface and ensure the cleanliness of the experimental environment; the four support legs 14 on the bottom of the cabinet 1 play a role in stabilizing and supporting the entire material collection table.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
