Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical storage technology, specifically a leak-proof hazardous chemical safety storage cabinet. Background Technology

[0002] Hazardous chemical storage cabinets are storage facilities specifically designed for the safe storage of hazardous chemicals. To ensure safety and environmental protection, existing hazardous chemical storage cabinets are typically equipped with ventilation systems. The main purpose of these ventilation systems is to prevent the accumulation of hazardous gases inside the cabinet, while also helping to maintain a stable environment within the cabinet and reducing the risk of potential chemical reactions caused by changes in temperature and humidity.

[0003] However, traditional storage cabinets often have a significant drawback in their ventilation design: they tend to allow free airflow between the inside and outside of the cabinet. This means that in the event of a leak of harmful gases inside the cabinet, these gases may be directly released into the external environment, causing air pollution and health threats. To address this, we offer a leak-proof hazardous chemical safety storage cabinet with excellent heat dissipation and the ability to prevent the leakage of harmful gases. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof safety storage cabinet for hazardous chemicals, which solves the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] A leak-proof safety storage cabinet for hazardous chemicals includes a cabinet body and a ventilation assembly. The ventilation assembly includes two ventilation ducts, a fan, a filter assembly, and a drive device. Each of the two ventilation ducts has an internal port communicating with the interior of the cabinet body and an external port extending outside the cabinet body. The fan is configured to circulate internal and external air through the ventilation ducts. The filter assembly contains filter material and is movable relative to the cabinet body in a first direction. Both ends of the filter assembly are aligned with the external ports of the two ventilation ducts in the first direction. The drive device is configured to drive the filter assembly to move along the first direction, such that the two ports of the filter assembly are connected to or disconnected from the external ports of the two ventilation ducts.

[0007] Optionally, the driving device is an electric driving device.

[0008] Optionally, the ventilation assembly further includes a detection mechanism, which includes a toxic gas sensor disposed inside the storage cabinet and a central controller electrically connected thereto, the central controller also being connected to the electric drive device.

[0009] Optionally, the filter tube assembly includes a material box and two connecting pipes. The material box has a box body and an openable and closable box cover located at the opening of the box body. The two connecting pipes are connected to opposite sides of the box body.

[0010] Optionally, the box body is provided with multiple partitions inside, which divide the interior of the box body into multiple material placement spaces, and ventilation holes are provided through the surface of the partitions.

[0011] Optionally, an air guide assembly is provided on the storage cabinet body located at the external port of the ventilation duct. The air guide assembly includes a cover fixed to the storage cabinet body and a movable plate pivotally connected to the cover body. The movable plate rotates relative to the cover body when the filter tube assembly moves in a first direction.

[0012] Optionally, the ventilation assembly further includes a rodent-proof mesh, which is disposed on the ventilation duct.

[0013] Compared with the prior art, this utility model provides a leak-proof safety storage cabinet for hazardous chemicals, which has the following advantages:

[0014] 1. This utility model uses a movable filter tube assembly with built-in filter material connected to a ventilation pipe. It uses a fan to circulate the air inside and outside the storage cabinet and purifies harmful gases through the filter material, thereby protecting the external environment from pollution. At the same time, it ensures the ventilation and cooling effect of the storage cabinet and improves the safety of hazardous chemical storage.

[0015] 2. This utility model, by setting up a filter tube assembly structure including a material box and two connecting pipes, achieves the effect of facilitating quick replacement of filter materials, simplifies the maintenance process of ventilation components, reduces the burden on staff, and improves the efficiency and safety of the entire leak-proof hazardous chemical safety storage cabinet.

[0016] 3. This utility model provides an air guide assembly consisting of a fixed cover and a movable plate at the external port of the ventilation duct. The movable plate rotates relative to the cover when the filter tube assembly moves, forming a semi-enclosed space. This prevents the hot air discharged from the ventilation duct from immediately re-entering the cabinet, thus avoiding the phenomenon of hot air circulation backflow, improving the cooling efficiency and overall safety of the storage cabinet. At the same time, the movable plate provides clearance for the connection between the filter tube assembly and the ventilation duct, ensuring the normal operation of the ventilation system and preventing the leakage of harmful gases.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figures 1 to 5According to an embodiment of the present invention, a technical solution is provided: a leak-proof hazardous chemical safety storage cabinet, comprising a storage cabinet body 1 and a ventilation assembly, wherein the ventilation assembly includes two ventilation pipes 2, a fan 3, a filter pipe assembly 4, and a drive device 5, wherein each of the two ventilation pipes 2 has an internal port 20 communicating with the interior of the storage cabinet body 1 and an external port 21 extending outside the storage cabinet body 1; the fan 3 is configured to circulate the internal and external air of the storage cabinet body 1 through the ventilation pipes 2, for example, the fan 3 can be installed at the location of at least one ventilation pipe 2, and the fan 3 is used to circulate the internal and external air of the storage cabinet body 1 through the ventilation pipes 2; the filter pipe assembly 4 has built-in filter material and is movable relative to the cabinet body in a first direction, and the two ends of the filter pipe assembly 4 are respectively aligned with the external ports 21 of the two ventilation pipes 2 in the first direction; the drive device 5 is configured to drive the filter pipe assembly 4 to move along the first direction, so that the two ports of the filter pipe assembly 4 are connected or disconnected from the external ports 21 of the two ventilation pipes 2. Under normal circumstances, the filter tube assembly 4 is not connected to the ventilation duct 2. The air inside and outside the storage cabinet 1 circulates through the ventilation duct 2 under the action of the fan 3. This internal air circulation method can better meet the ventilation and cooling needs of the storage cabinet 1. However, when the concentration of harmful gases inside the storage cabinet 1 is too high, the filter tube assembly 4 can be driven by the drive device 5 to connect it to the two ventilation ducts 2. In this way, the air containing harmful gases circulates between the storage cabinet 1 and the filter tube assembly 4 under the action of the fan 3. At the same time, the filter material (such as activated carbon) built into the filter tube assembly 4 adsorbs and purifies the harmful substances in the harmful gases. This internal circulation method can effectively prevent the leakage of harmful gases and protect the external environment.

[0025] In this exemplary embodiment, the drive device 5 is an electric push rod. Of course, the drive device 5 can also be an electric drive device such as a linear motor or an electric lead screw.

[0026] In this exemplary embodiment, the ventilation assembly further includes a detection mechanism, which comprises a toxic gas sensor 6 disposed within the storage cabinet 1 and a central controller 7 electrically connected thereto. The central controller 7 is also connected to an electric drive device. The toxic gas sensor 6 can monitor the concentration of harmful gases inside the storage cabinet 1 in real time and transmit the data to the central controller 7. The central controller 7 controls the operation of the electric drive device based on the received data, thereby enabling timely connection of the filter tube assembly 4 to the two ventilation ducts 2 when the concentration of harmful gases inside the storage cabinet 1 is too high, ensuring the health and safety of personnel and the normal operation of the facility.

[0027] In this exemplary embodiment, the filter assembly 4 includes a material box 40 and two connecting pipes 41. The material box 40 has a box body 400 and an openable and closable lid 401 located at the opening of the box body 400. The two connecting pipes 41 are connected to opposite sides of the box body 400. To enable quick replacement of the filter material, the material box 40 is designed with an openable and closable lid 401 located at the opening of the box body 400, allowing personnel to easily open the lid 401 to access the filter material inside the box body 400. Furthermore, the lid 401 of the material box 40 can be fitted with a sealing element to ensure airtightness, preventing gas leakage while facilitating opening. The two connecting pipes 41 are connected to opposite sides of the box body 400, connecting the material box 40 to the rest of the ventilation assembly, ensuring that gas can be filtered through the material box 40. This structure not only facilitates the replacement of the filter material but also ensures the airtightness and safety of the entire system during ventilation. With the above design, the filter assembly 4 can effectively remove harmful components from the passing air, while its ease of operation also reduces the maintenance burden on staff.

[0028] In this exemplary embodiment, the box body 400 is internally provided with multiple partitions 8, which divide the interior of the box body 400 into multiple material placement spaces. Ventilation holes 9 are provided through the surfaces of the partitions 8. To improve the filtration efficiency and versatility of the filter assembly 4, the box body 400 is designed with multiple partitions 8. These partitions 8 divide the interior of the box body 400 into multiple independent material placement spaces, allowing different types of filter materials, such as activated carbon, molecular sieves, or other adsorbents, to be placed in different spaces. Each material targets specific harmful gas molecules for efficient adsorption. The partitions 8 are designed with ventilation holes 9, which not only allow air to circulate between the various material placement spaces but also ensure that the gas flows evenly through the various filter materials, thereby fully absorbing and removing different target molecules in the harmful gases. This structural design utilizes the different properties of various filter materials, and through combined use, can broadly remove a variety of harmful gases released by hazardous chemicals, providing more comprehensive safety protection. For example, some filter materials may have a high affinity for certain organic compounds, while other materials may be more effective at adsorbing acidic or alkaline gases.

[0029] In this exemplary embodiment, an air guide assembly is provided on the storage cabinet 1 located at the external port 21 of the ventilation duct 2. The air guide assembly includes a cover 10 fixed to the storage cabinet 1 and a movable plate 11 pivotally connected to the cover 10. The movable plate 11 rotates relative to the cover 10 when the filter tube assembly 4 moves in a first direction. When the port of the filter tube assembly 4 leaves the ventilation duct 2, the movable plate 11 automatically rotates to the closed position, covering the port of the filter tube assembly 4. At this time, the movable plate 11, the cover 10, and the storage cabinet 1 enclose a semi-enclosed space with an opening on one side. This unique design ensures that the opening directions of the semi-enclosed spaces formed by the air guide assemblies at the two ventilation duct 2 positions are opposite, preventing the recirculation of hot air. That is, it prevents the hot air discharged from one ventilation duct 2 from immediately re-entering the storage cabinet through the other ventilation duct 2, which is crucial for maintaining the cooling effect of the storage cabinet 1. When the filter tube assembly 4 needs to dock with the ventilation duct 2, the movable plate 11 again demonstrates its flexibility, rotating relative to the cover 10 to provide the necessary clearance for the movement of the filter tube assembly 4. In this way, the filter tube assembly 4 can be smoothly connected to the external port 21 of the ventilation duct 2 to restore or establish a sealed connection, ensuring the normal operation of the ventilation system while preventing harmful gases from escaping.

[0030] In this exemplary embodiment, the ventilation assembly also includes a rodent-proof mesh 12 disposed on the ventilation duct 2. The rodent-proof mesh 12 may be made of a sturdy material, and its mesh size is designed to prevent rats and other small animals of similar size from penetrating, while allowing air to circulate freely. This mesh structure does not significantly affect ventilation performance, ensuring that gas exchange between the inside and outside of the storage cabinet is not affected, while also providing an additional physical barrier.

[0031] Working principle: Under normal conditions, the filter tube assembly 4 is not connected to the ventilation duct 2, and the fan 3 maintains the air circulation inside and outside the cabinet to meet the ventilation and cooling requirements; when the concentration of harmful gases inside the cabinet increases, the central controller 7 receives the data from the toxic gas sensor 6 and instructs the drive device 5 (e.g., an electric push rod) to connect the filter tube assembly 4 to the ventilation duct 2. In this way, the air containing harmful substances circulates through the filter tube assembly 4 under the action of the fan 3, where the harmful substances are adsorbed and purified to prevent leakage.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
