Description

Technical Field

[0001] This invention belongs to the field of hazardous chemicals technology, specifically relating to an emergency adsorption and recovery device for hazardous chemical leaks. Background Technology

[0002] In various locations involving hazardous chemicals, such as chemical plants, research laboratories, and hazardous chemical transport vehicles, hazardous chemical leaks remain a significant potential safety hazard. Hazardous chemicals possess dangerous characteristics such as flammability, explosiveness, toxicity, and corrosivity. Once a leak occurs, it not only poses a serious threat to human life but can also cause irreversible damage to the surrounding environment, leading to a series of problems including environmental pollution and ecological imbalance.

[0003] Scientific research laboratories are also high-risk locations for hazardous chemical leaks. During operations, leaks can occur due to accidental spills of reagent bottles, malfunctions in experimental equipment, or other reasons. Laboratories contain a wide variety of hazardous chemicals with complex compositions; some highly toxic or volatile substances, once leaked, can rapidly spread within a confined space, posing a direct threat to the safety of personnel within the laboratory. Furthermore, laboratories are typically located in densely populated buildings, and improper handling of leaks could potentially lead to larger-scale safety incidents.

[0004] Currently, the methods and devices for handling hazardous chemical leaks have certain limitations. Traditional methods often rely on manual operation, which is inefficient and inaccurate. For example, when using adsorbent materials for adsorption treatment, the adsorbent needs to be manually and evenly spread on the leak area. This is not only cumbersome, but also makes it difficult to ensure the comprehensiveness and uniformity of the adsorbent coverage, which can easily lead to some leaked hazardous chemicals not being dealt with in a timely and effective manner.

[0005] Existing adsorption and recovery devices are often complex in structure and difficult to operate, requiring specialized personnel for operation and maintenance. This can lead to missed opportunities for optimal response in emergencies, such as sudden hazardous chemical leaks. Furthermore, these devices are typically single-function, only suitable for specific types or areas of hazardous chemical leaks, lacking flexibility and versatility. For example, existing small adsorption devices are often insufficient for large-area hazardous chemical leaks to handle them quickly and effectively; while for small-area leaks, large devices are too bulky and cumbersome to operate.

[0006] Furthermore, some existing adsorption and recovery devices are inadequate in isolating leak areas. After a hazardous chemical leak, the failure to promptly and effectively seal and isolate the leak area allows the hazardous chemicals to spread further, increasing the difficulty and risk of handling the situation. Moreover, during the adsorption process, insufficient contact between the adsorbent and the hazardous chemicals affects the adsorption effect, resulting in hazardous chemical residues and failing to completely resolve the leak problem.

[0007] To address this, we propose an emergency adsorption and recovery device for hazardous chemical leaks. This device can not only handle hazardous chemicals of varying sizes, but also features a simple structure and rapid operation, achieving time and labor savings. Utility Model Content

[0008] The purpose of this invention is to provide an emergency adsorption and recovery device for hazardous chemical leaks. This device can not only handle hazardous chemicals of different sizes, but also has a simple structure, is quick to use, and achieves the effect of saving time and effort.

[0009] The specific technical solution adopted in this utility model is as follows:

[0010] An emergency adsorption and recovery device for hazardous chemical leaks includes a support rod, a U-shaped frame at the bottom of the support rod, a rotating component and a traveling component on the U-shaped frame, and an adsorption and isolation component on the rotating component.

[0011] The adsorption and isolation assembly includes a hollow hexagonal support shell disposed on the rotating assembly. The hollow hexagonal support shell contains an adsorbent. Each of the six faces of the hollow hexagonal support shell has a conical guide shell of different size. Each conical guide shell has a hexagonal block on one side. Each of the six faces of the hexagonal block has an isolation cavity of different size and area. The six isolation cavities correspond one-to-one with the six conical guide shells. A flipping assembly is disposed at the connection between the hollow hexagonal support shell and the conical guide shell.

[0012] Furthermore, the walking assembly includes a slide groove formed on a U-shaped frame, a fixed shaft is provided inside the slide groove, a slider and a spring are sleeved on the fixed shaft, the top of the slider is connected to the spring, and an L-shaped bracket is provided on one side of the slider, with a self-locking pulley provided on the L-shaped bracket.

[0013] Furthermore, the rotating assembly includes a first motor mounted on a U-shaped frame, with a first rotating shaft mounted on the output end of the first motor, and the end of the first rotating shaft away from the first motor passing through the hollow hexagonal support housing.

[0014] Furthermore, the flipping assembly includes a cavity formed at the connection between the hollow hexagonal support shell and the conical guide shell. A second rotating shaft is provided inside the cavity, and a flipping plate matching the cavity is provided on the second rotating shaft. A second motor is installed at one end of the second rotating shaft, and the second motor is connected to the hollow hexagonal support shell.

[0015] Furthermore, a sealing adsorption strip is installed at the bottom of each of the isolation chambers.

[0016] Furthermore, the hollow hexagonal bearing housing is provided with a feed inlet.

[0017] Furthermore, a handle is provided on the support rod.

[0018] The technical effects achieved by this utility model are as follows:

[0019] In the event of a hazardous chemical liquid leak (accidental breakage) in the laboratory, adsorbent is added to the hollow cavity of the hollow hexagonal support shell. Holding the support rod, the U-shaped frame moves to the leak location via the walking assembly. The rotating assembly, based on the leak area, activates the hollow hexagonal support shell, causing the conical guide shell to rotate the appropriate side of the hexagonal block above the hazardous chemical. Pressing down seals the isolation chamber over the leak area. At this point, the adsorbent accumulates above the required isolation chamber due to gravity. The flipping assembly opens the connection between the hollow hexagonal support shell and the conical guide shell, allowing the adsorbent to enter the isolation chamber for adsorption. After adsorption is complete, the entire device can be moved for cleaning. This device can handle hazardous chemicals of varying sizes, is simple in structure, and is quick to use, saving time and labor. Attached Figure Description

[0027] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figures 1-4 As shown, the specific technical solution adopted in this utility model is as follows: an emergency adsorption and recovery device for hazardous chemical leaks, including a support rod 1, a U-shaped frame 2 at the bottom of the support rod 1, a rotating component and a walking component on the U-shaped frame 2, and an adsorption and isolation component on the rotating component;

[0029] The adsorption and isolation assembly includes a hollow hexagonal support shell 3 mounted on a rotating assembly. The hollow hexagonal support shell contains an adsorbent. Each of the six faces of the hollow hexagonal support shell 3 has a conical guide shell 4 of different sizes. Each conical guide shell 4 has a hexagonal block 7 on one side. Each of the six faces of the hexagonal block 7 has an isolation cavity 8 of different sizes. The six isolation cavities 8 correspond one-to-one with the six conical guide shells 4. A flipping assembly is provided at the connection between the hollow hexagonal support shell 3 and the conical guide shell 4.

[0030] The walking component includes a slide groove 9 on a U-shaped frame 2. A fixed shaft 10 is provided inside the slide groove 9. A slider 11 and a spring 12 are sleeved on the fixed shaft 10. The top of the slider 11 is connected to the spring 12. An L-shaped bracket 13 is provided on one side of the slider 11. A self-locking pulley is provided on the L-shaped bracket 13.

[0031] When in use, by holding the support rod 1, the U-shaped frame 2 is driven, which in turn drives the L-shaped bracket 13 to move the self-locking slider 11 on the bottom surface (at this time, the elastic force of the spring 12 keeps the hexagonal block 7 at a certain distance from the bottom surface). Then, when absorbing hazardous chemicals, by pressing the support rod 1, the support rod 1 drives the U-shaped frame 2 to move the slider 11 inside the slide groove 9 and squeeze the spring 12, so that the isolation chamber 8 of the hexagonal block 7 is in close contact with the bottom surface, thereby achieving the isolation of hazardous chemicals.

[0032] It should be noted that the selection of spring 12 should be calculated using Hooke's Law to determine the required spring 12. This method uses existing technology and will not be elaborated on here.

[0033] Meanwhile, the rotating assembly includes a first motor 14 mounted on the U-shaped frame 2. The output end of the first motor 14 is equipped with a first rotating shaft. The end of the first rotating shaft away from the first motor 14 passes through the hollow hexagonal bearing housing 3. The first motor 14 drives the first rotating shaft to make the hollow hexagonal bearing housing 3 drive the hexagonal block 7 to rotate, thereby dealing with hazardous chemical leaks of different areas.

[0034] This utility model is provided with six sets of isolation chambers 8, but seven or eight sets can also be provided. The size of each isolation chamber 8 is different, which can be adapted to 50-500cm. 2 The leakage area range is improved by 3 times compared with traditional fixed adsorption devices. The setting of isolation chamber 8 is existing technology and will not be elaborated on here.

[0035] The flipping assembly includes a cavity formed at the junction of the hollow hexagonal support housing 3 and the conical guide housing 4. A second rotating shaft is provided inside the cavity, and a flipping plate 15 matching the cavity is provided on the second rotating shaft. A second motor 16 is installed at one end of the second rotating shaft and is connected to the hollow hexagonal support housing 3.

[0036] The second motor 16 drives the second rotating shaft to rotate the flip plate 15, thereby connecting the hollow hexagonal bearing shell 3, the conical guide shell 4, and the isolation chamber 8, allowing the adsorbent to pass through.

[0037] The adsorbent can be Stardust, which can adsorb, absorb, and solidify all liquids and semi-liquid substances (except hydrofluoric acid), including oils (gasoline, diesel, aviation kerosene, engine oil, hydraulic oil, brake fluid, gearbox oil, lubricating oil, grease, etc.); chemical liquids (herbicides, pesticides, pesticides, acetone, toluene, sulfuric acid, hydrochloric acid, alkalis, various water-based, oil-based, or epoxy-based paints, antifreeze, polymers, etc.); all animal fats, vegetable oils, butter, honey, vinegar, beverages, etc. It absorbs quickly and efficiently (using less adsorbent). It can absorb and solidify liquids of any viscosity, reduce the toxicity of chemicals, keep floors clean and dry, and is effective against any substance. It does not harm soil, cement floors, asphalt, tiles, factories, animals, or humans. It does not contain reactive compounds, is non-toxic, non-flammable, but biodegradable, environmentally friendly, and safe. This is existing technology and will not be elaborated further here.

[0038] Each isolation chamber 8 is equipped with a sealing absorbent strip 17 at the bottom, which is made of rubber and absorbent cotton. It is not only deformable to adapt to different bottom surfaces, but also the absorbent cotton can prevent leakage.

[0039] The hollow hexagonal bearing shell is equipped with a feed inlet, through which the adsorbent enters. When the adsorbent enters, it is sealed by a sealing block.

[0040] The support rod 1 is equipped with a handle for easy use.

[0041] The working principle of this invention is as follows: When a hazardous chemical liquid leaks (accidentally breaks) in the laboratory, the adsorbent is added to the hollow cavity of the hollow hexagonal support shell 3. Then, the support rod 1 is held, and the support rod 1 drives the U-shaped frame 2 to move to the leak location via the walking component. Then, based on the leak area, the rotating component is activated. The rotating component drives the hollow hexagonal support shell 3, causing the conical guide shell 4 to rotate the appropriate side of the hexagonal block 7 above the hazardous chemical. Then, pressing down seals the isolation chamber 8 over the leak area. At this time, the adsorbent gathers above the isolation chamber 8 due to gravity. By flipping the component, the connection between the hollow hexagonal support shell 3 and the conical guide shell 4 is opened, allowing the adsorbent to enter the isolation chamber 8 for adsorption. After adsorption is complete, the entire device can be moved for cleaning. This device can not only treat hazardous chemicals of different areas, but also has a simple structure, is quick to use, and achieves the effect of saving time and labor.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
