Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, specifically a high-temperature laboratory table with a protective structure. Background Technology

[0002] Laboratory high-temperature tables are commonly used equipment in laboratories. They are mainly used for experimental operations that require high-temperature conditions, providing a stable high-temperature environment for various chemical and physical experiments. Their tops are usually covered with heat-insulating materials to prevent operators from being burned by high temperatures and to ensure basic safety during the experimental process.

[0003] Alcohol lamps are often used as heating tools during the operation of high-temperature workbenches. However, due to accidental contact, equipment vibration, or other unforeseen circumstances, alcohol lamps are prone to tipping over. Once tipped over, the alcohol inside will spill out and flow down the tabletop of the high-temperature workbench. If it spills onto the ground, it can easily spread and cause a fire, damaging the experimental equipment and potentially endangering the personal safety of the personnel, thus posing a limitation.

[0004] The reason for this problem is that alcohol lamps can tip over in various ways. Besides accidental activation and equipment vibration, factors such as uneven surfaces and unstable lamp placement can also cause them to tip over. The danger of a spreading fire is immense. Alcohol is a flammable liquid, and the flame spreads rapidly, igniting other flammable materials in the laboratory and causing a larger fire. Therefore, we propose a high-temperature laboratory platform with a protective structure to address these issues. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a laboratory high-temperature platform with a protective structure, which solves the problem that if an alcohol lamp tipes over, the alcohol inside will leak out and flow down the table of the high-temperature platform. If it flows onto the ground, it can easily cause a fire that spreads, damaging experimental equipment and potentially endangering the personal safety of experimental personnel.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a laboratory high-temperature table with a protective structure, comprising a table body, the top of which is covered with heat insulation material, and a protective unit provided inside the table body, the protective unit comprising a collection trough, a collection box, and a nitrogen gas component;

[0007] The collection tank is located inside the platform and is used to collect liquid. The collection box is located below the platform and is connected to the collection tank. The nitrogen gas supply is located below the collection box and is connected to the collection box. The nitrogen gas supply is used to inject nitrogen gas into the collection box.

[0008] Preferably, the platform body has a groove inside, and a boss is fixedly installed inside the groove. The corners of the boss are arc-shaped, and the collection groove is opened inside the groove.

[0009] Preferably, the collection tank has an outlet inside, and the bottom of the collection tank is curved, and the collection tank is used to guide the liquid to the outlet.

[0010] Preferably, the discharge port is provided with a filter element, which includes a filter basket, an arc-shaped gripper and a magnetic ring;

[0011] The arc-shaped gripper is fixedly assembled inside the filter basket; the magnetic ring is fixedly assembled at the bottom of the filter basket.

[0012] Preferably, a connecting pipe is fixedly assembled at the bottom of the platform, and the magnetic ring is magnetically connected to the top of the connecting pipe.

[0013] Preferably, the outer surface of the connecting pipe is fitted with a heat insulation sleeve, and the top of the collection box is provided with a connecting pipe, which is threadedly engaged with the heat insulation sleeve.

[0014] Preferably, the nitrogen gas component includes a support plate and a conduit;

[0015] The support plate is fixedly assembled on one side of the platform, and the support plates are arranged in a vertical array; one end of the conduit is connected to the collection box.

[0016] Preferably, the nitrogen component further includes a solenoid valve and a nitrogen cylinder;

[0017] The solenoid valve is located at one end of the conduit; the nitrogen tank is located at the other end of the conduit, and the nitrogen tank is connected to the conduit.

[0018] This utility model discloses a laboratory high-temperature platform with a protective structure, which has the following beneficial effects: when an alcohol lamp tipps over and alcohol spills out, the collection tank can collect the alcohol in time, preventing it from flowing down the tabletop onto the ground and thus avoiding the spread of fire, thereby improving laboratory safety. The nitrogen component injects nitrogen into the collection tank. Since nitrogen is an inert gas and does not support combustion, it can isolate the alcohol in the collection tank from contact with air, thereby preventing the alcohol from being ignited in the collection tank, further ensuring laboratory safety.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. 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.

[0027] This application provides a laboratory high-temperature platform with a protective structure, which solves the problem that if an alcohol lamp tipps over, the alcohol will leak out and flow down the table of the high-temperature platform. If it flows onto the ground, it can easily cause a fire that spreads, damaging the experimental equipment and potentially endangering the personal safety of the experimental personnel.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] This utility model provides, for example Figure 1-3 The image shows a high-temperature laboratory table with a protective structure.

[0030] Example 1: Includes a platform 1, the top of which is covered with heat insulation material, and a protective unit 2 is provided inside the platform 1. The protective unit 2 includes a collection tank 21, a collection box 22, and a nitrogen gas component 23.

[0031] The collection tank 21 is located inside the platform 1 and is used to collect liquid. The collection box 22 is located below the platform 1 and is connected to the collection tank 21. The nitrogen gas supply unit 23 is located below the collection box 22 and is connected to the collection box 22. The nitrogen gas supply unit 23 is used to inject nitrogen into the collection box 22.

[0032] The platform 1 has a recess 24 inside, and a boss 25 is fixedly installed inside the recess 24. The corners of the boss 25 are rounded. A collection tank 21 is opened inside the recess 24, and a discharge port 26 is opened inside the collection tank 21. The bottom of the collection tank 21 is rounded. The collection tank 21 is used to guide liquid to the discharge port 26. A filter element 27 is installed inside the discharge port 26. The filter element 27 includes a filter basket 271, an arc-shaped gripper 272, and a magnetic ring 273. The arc-shaped gripper 272 is fixedly installed inside the filter basket 271. The magnetic ring 273 is fixedly installed at the bottom of the filter basket 271. A connecting pipe 28 is fixedly installed at the bottom of the platform 1. The magnetic ring 273 is magnetically connected to the top of the connecting pipe 28. A heat insulation sleeve 29 is sleeved on the outer surface of the connecting pipe 28. A connecting pipe is provided at the top of the collection box 22. The connecting pipe is threadedly engaged with the heat insulation sleeve 29.

[0033] In this embodiment, when the alcohol lamp tipps over and alcohol spills out, it is first collected by the collection trough 21 in the groove 24. Guided by the arc at the bottom of the collection trough 21, the alcohol flows through the outlet 26 and is filtered by the filter element 27 before flowing into the collection box 22 for storage via the connecting pipe 28. At this time, the solenoid valve 233 is opened, and nitrogen from the nitrogen tank 234 enters the collection box 22 through the conduit 232, isolating the alcohol from contact with air. When it is necessary to clean the collection box 22 or replace the filter element 27, the collection box 22 can be removed by threaded connection, and the filter basket 271 can be removed by the arc-shaped gripper 272.

[0034] This utility model discloses a laboratory high-temperature stage with a protective structure. More specifically, based on Embodiment 1, it is provided according to the appendix... Figure 1 , 4 As shown in Figure 5.

[0035] Example 2: Includes a platform 1, the top of which is covered with heat insulation material, and a protective unit 2 is provided inside the platform 1. The protective unit 2 includes a collection tank 21, a collection box 22, and a nitrogen gas component 23.

[0036] The collection tank 21 is located inside the platform 1 and is used to collect liquid. The collection box 22 is located below the platform 1 and is connected to the collection tank 21. The nitrogen gas supply unit 23 is located below the collection box 22 and is connected to the collection box 22. The nitrogen gas supply unit 23 is used to inject nitrogen into the collection box 22.

[0037] The nitrogen component 23 includes a support plate 231 and a conduit 232; the support plate 231 is fixedly mounted on one side of the platform 1 and is arranged in a vertical array; one end of the conduit 232 is connected to the collection box 22. The nitrogen component 23 also includes a solenoid valve 233 and a nitrogen tank 234; the solenoid valve 233 is located at one end of the conduit 232; the nitrogen tank 234 is located at the other end of the conduit 232 and is connected to the conduit 232.

[0038] In this embodiment, the heat insulation material is marble. The operator opens the solenoid valve 233, and nitrogen gas from the nitrogen tank 234 quickly enters the collection box 22 through the conduit 232. Since nitrogen is slightly less dense than air, it gradually accumulates in the collection box 22, displacing the air inside and thus isolating the burning alcohol from oxygen. Simultaneously, the nitrogen absorbs heat from the surrounding environment during release, lowering the temperature inside the collection box 22 and further inhibiting alcohol combustion. When the oxygen concentration in the collection box 22 decreases to a certain level and the temperature drops below the ignition point of the alcohol, the burning alcohol will extinguish, effectively preventing the spread of the flame.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
