Description

Technical Field

[0001] The present invention belongs to the technical field of hazardous chemical management equipment, and in particular relates to intelligent hazardous chemical management equipment. Background Art

[0002] Hazardous chemicals refer to highly toxic chemicals and other chemicals that have properties such as poisoning, corrosiveness, explosion, combustion, and combustion-supporting, and are harmful to human body, facilities, and the environment. Therefore, when university laboratories, hospitals, chemical plants and other places need to store large quantities of such chemicals, they need equipment that can ensure a good storage environment and has certain intelligent management effects to assist in storage and thus ensure safety.

[0003] In the prior art, Chinese patent No. CN218384033U discloses an intelligent management device for hazardous chemicals, comprising: a locker, a control cabinet being fixed to the outer wall at one end of the locker, a computer, a controller and a signal transmitter being installed inside the control cabinet; an identification component, the identification component comprising a support, a camera component and a transmission component, a sliding groove opening being opened on the outer wall at one end of the support, the transmission component being installed inside the sliding groove opening, the camera component being installed on the transmission component, the support being fixed to the outer wall at one end of the locker, two relatively aligned cabinet doors being hingedly installed on the outer wall at one end of the locker, an electronic lock being installed on one side outer wall of one of the cabinet doors, and a lock position adapted to the electronic lock being installed on one side outer wall of the other cabinet door, a plurality of transversely arranged placement cavities being opened inside the locker, and the above-mentioned utility model can reduce the risk of personal injury.

[0004] In the existing technology, the image after collection is judged by the image recognition and detection program in the recognition component computer. If it is qualified, the locker is opened. This can reduce the risk of personal injury, but there are still certain shortcomings in overall use: First, although the above-mentioned existing technology can open the cabinet door through facial recognition, the specific records of hazardous chemicals, such as the usage time and the amount used each time, still need to be recorded manually. For users, the overall workload has not been reduced. In addition to the high time cost, manual work also has the possibility of missing records, and the overall management rigor needs to be improved. Secondly, many hazardous chemicals emit toxic or harmful gases during storage. Furthermore, dust accumulates inside the storage cabinet when hazardous chemicals are removed and placed. If the storage environment is closed, these gases can accumulate, potentially causing poisoning, fire, or explosion. Therefore, existing devices often use gas circulation combined with activated carbon plates and other structures for adsorption and purification to ensure safety within the management equipment. However, existing devices cannot guarantee ventilation and often use high-speed gas flow, which results in the activated carbon being unable to fully adsorb pollutants and may even release adsorbed substances again, greatly reducing its effectiveness. Finally, during use, the activated carbon plates in the prior art only briefly contact the polluted air with the activated carbon plates before being discharged to the outside. The area and time of contact between the polluted air and the activated carbon plates are relatively short, resulting in poor adsorption of pollutants in the air, thereby reducing the air purification effect. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, the present invention provides an intelligent hazardous chemical management device. This device addresses the labor-intensive process of manually recording the users, usage times, and usage quantities of hazardous chemicals, as well as the issue of excessive ventilation pressure, which weakens the adsorption capacity of activated carbon. Furthermore, it addresses the technical issue of polluted air being directly discharged through the activated carbon, resulting in a relatively short contact area and duration with the activated carbon plates, leading to poor adsorption of pollutants within the air.

[0006] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: A hazardous chemical intelligent management device includes a storage cabinet, a cabinet door is hingedly connected to the front surface of the storage cabinet, a control panel is provided on the surface of the cabinet door, a face recognition module is provided above the control panel, a code scanner is provided below the control panel, and a weighing tray is provided below the code scanner. A plurality of mounting tubes for placing hazardous chemicals are provided inside the storage cabinet, which are used to place hazardous chemical bottles.

[0013] By setting up the activated carbon plate and the arc-shaped disk, the vertical airflow can be dispersed outward and directed upward, so that the wind pressure on the activated carbon plate is reduced. The low-speed airflow may enable the activated carbon to fully adsorb pollutants.

[0014] In the above-mentioned intelligent management equipment for hazardous chemicals, a conical seat is provided inside the connecting pipe, a mounting shaft is rotatably installed on the top of the conical seat, and a plurality of staggered first fan blades and second fan blades are fixedly installed on the outer surface of the mounting shaft, and the inclination angle of the first fan blade is greater than the inclination angle of the second fan blade.

[0015] Through the arrangement of the conical seat, the first fan blade, the second fan blade and the filter, the dust on the filter can be shaken off by utilizing the difference in wind pressure while the storage cabinet passes through, thus preventing dust from accumulating on the surface of the filter and clogging the filter, thereby greatly improving the use effect.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Example 1: A hazardous chemicals intelligent management device, reference Figure 1 , including a storage cabinet 10, a support leg 11 is fixedly installed on the lower surface of the storage cabinet 10, a cabinet door 12 is hinged on the front surface of the support leg 11, a control panel 13 is fixedly installed on the front surface of the cabinet door 12, and a face recognition module 14 is fixedly installed on the surface of the storage cabinet 10 above the control panel 13. When in use, the user is located directly in front of the face recognition module 14, and the face recognition module 14 identifies the identity of the user. After successful identification, the cabinet door 12 is opened to take and put hazardous chemicals. It should be noted here that due to the large variety of hazardous chemicals, the three words "hazardous chemicals" in this article mean bottles containing hazardous chemicals. The bottles are sealed when placed in and have an identity code on the bottle body. The specific hazardous chemicals are liquids or solids, etc. This solution does not make too many restrictions and elaborations.

[0031] For further reference, Figure 1 A barcode scanner 15 is fixedly installed on the surface of the cabinet door 12 below the control panel 13, and a weighing tray 16 is fixedly installed on the surface of the cabinet door 12 below the barcode scanner 15. When in use, the user takes out the hazardous chemicals and scans the identity code of the bottle through the barcode scanner 15. The scanning result is displayed on the control panel 13 and registered and timed. After scanning, the hazardous chemical bottle is placed on the upper surface of the weighing tray 16 for weighing, and the control panel 13 records the weight. When the hazardous chemicals are put back, they need to be scanned and weighed again. The control panel 13 records the time and weight of the return. The use record of hazardous chemicals can also be retrieved and viewed at any time through the control panel 13, thereby realizing intelligent management of hazardous chemicals.

[0032] For further reference, Figure 3 and Figure 4 The inner walls on both sides of the storage cabinet 10 are provided with slide grooves 17, and a bracket 18 is slidably installed inside the slide groove 17. A mounting frame 19 is fixedly installed inside the bracket 18, and a mounting cylinder 20 is fixedly installed at the end of the mounting frame 19 for placing hazardous chemicals. When in use, the cabinet door 12 is opened and the mounting cylinder 20 can be pulled out through the handle on the front surface of the bracket 18, which is convenient for taking and placing hazardous chemicals and greatly improves work efficiency.

[0033] For further reference, Figure 3 、 Figure 6 and Figure 8 , a sleeve 23 with an internal hollow setting is fixedly installed inside the mounting cylinder 20, a pressure sensor 24 is fixedly installed inside the sleeve 23, a spring 25 fixedly installed inside the sleeve 23 is sleeved on the outside of the pressure sensor 24, a base 26 is slidably installed on the top of the sleeve 23, a plurality of fixed blocks 29 are fixedly installed on the inner wall of the mounting cylinder 20, a pressure block 30 is rotatably installed inside the fixed block 29, and a rubber clamping block 31 is fixedly installed on one end of the pressure block 30. In this solution, the base 26 has a cylindrical part that slides with the sleeve 23, and a disc-shaped placement part is provided on the top; when in use, the hazardous chemical bottle is removed from the top of the mounting cylinder 20 When the bottle is placed in the container, the support 26 is driven to slide downward, and the spring 25 and the pressure sensor 24 are squeezed. When the pressure sensor 24 is squeezed, a signal is transmitted to the control panel 13, indicating that the hazardous chemical bottle is placed. When the support 26 moves downward, the bottom surface of the disc of the support 26 will come into contact with the pressure block 30, so that the pressure block 30 can be tilted and pressed downward. The downward pressed pressure block 30 will drive the clamping block 31 to be pressed toward the support 26 until the end of the clamping block 31 comes into contact with the outer circular surface of the hazardous chemical, thereby fixing the hazardous chemical. Since the clamping block 31 is made of rubber, it can avoid damaging the hazardous chemical due to excessive clamping force, greatly improving the use effect.

[0034] For further reference, Figure 8A counter 27 and a humidity sensor 28 are fixedly installed on the outside of the spring 25. When the pressure sensor 24 receives pressure, it transmits the signal to the counter 27 for counting, so that the specific placement time can be calculated, further improving the intelligence of management. The humidity sensor 28 is used to detect the humidity inside the installation tube 20 to prevent the deterioration of hazardous chemicals.

[0035] For further reference, Figure 4 and Figure 5 The bottom of the inner cavity of the storage cabinet 10 is fixedly installed with a conical air inlet pipe 60 for air to enter the storage cabinet 10 from the inside of the air inlet pipe 60. A dust filter is provided on the top of the air inlet pipe 60 to prevent external dust from entering and avoid affecting the storage of hazardous chemicals, which greatly improves the use effect. A hollow plate 32 is fixedly installed on the top of the inner cavity of the storage cabinet 10. A plurality of motors 33 are fixedly installed on the upper surface of the hollow plate 32. An exhaust fan blade 35 is fixedly installed on the output end of the motor 33. An exhaust pipe 34 is fixedly installed on the top of the storage cabinet 10 and is sleeved on the outside of the exhaust fan blade 35. A dustproof cover is provided on the top of the exhaust pipe 34. Net 50, when in use, the motor 33 works to drive the exhaust fan blades 35 to rotate, and the exhaust fan blades 35 rotate to discharge the air inside the storage cabinet 10, and cooperate with the air inlet pipe 60 to complete the gas flow processing inside the storage cabinet 10, which can adjust the temperature and humidity, prevent chemicals from deteriorating or decomposing due to high temperature or high humidity, and can promptly discharge volatile toxic or harmful gases in the cabinet to avoid gas accumulation and reduce the risk of fire or explosion. In the above scheme, moisture-absorbing shelves or additional fans and other structures can also be installed inside the air inlet pipe 60. This scheme does not impose too many restrictions and can be adjusted according to actual usage.

[0036] For further reference, Figure 4 and Figure 5 The outer wall of the mounting cylinder 20 is wavy in shape to reduce air resistance and facilitate the upward flow of air inside the storage cabinet 10. A plurality of first air holes 21 are provided at the bottom of the mounting cylinder 20 for air to pass through the mounting cylinder 20, facilitating ventilation and dehumidification of the hazardous chemical bottles inside the mounting cylinder 20. A plurality of upwardly inclined second air holes 22 are also provided on the surface of the mounting cylinder 20, which can further improve the gas circulation efficiency inside and outside the mounting cylinder 20 and improve the storage effect.

[0037] It should be noted here that the control panel 13, facial recognition module 14, barcode scanner 15, weighing tray 16, pressure sensor 24, counter 27 and humidity sensor 28 are all conventional existing technologies as a whole, and they only need to be able to complete signal transmission normally. Therefore, this solution will not elaborate on the electrical control method, specific structure (signal transmission method, electrical connection between each sensor), etc. of the control panel 13, facial recognition module 14, barcode scanner 15, weighing tray 16, pressure sensor 24, counter 27 and humidity sensor 28.

[0038] Example 2: A hazardous chemicals intelligent management device, based on the first embodiment, is further implemented, referring to Figure 3 、 Figure 6 、 Figure 9 and Figure 10 , the inner wall of the exhaust pipe 34 is fixedly mounted with a conical tube 36 made of elastic metal material, and the conical tube 36 is detachable, and a mounting plate 37 is fixedly mounted on the top of the conical tube 36, and a connecting tube 38 is mounted on the internal thread of the mounting plate 37, and a conical seat 39 with a cone shape and a hollow interior is fixedly mounted on the interior of the connecting tube 38, and a plurality of through holes are provided on the top of the conical seat 39, and a mounting shaft 40 is rotatably mounted on the outer surface of the mounting shaft 40, and a plurality of staggered first blades 41 and second blades 42 are fixedly mounted, and the inclination angle of the first blade 41 is greater than the inclination angle of the second blade 42, and an activated carbon plate 45 inside the exhaust pipe 34 is fixedly mounted above the connecting tube 38 for purifying the ventilated air to prevent the toxic gas of hazardous chemicals from being discharged and polluting the surrounding working environment, and an elastic filter screen 43 is fixedly mounted between the lower surface of the activated carbon plate 45 and the top of the connecting tube 38; Specifically, when in use, the motor 33 drives the exhaust fan blades 35 to rotate and guide the air in the cabinet upward. The blown wind will flow toward the conical tube 36 and the conical seat 39. Since the conical seat 39 is conical, the air flow rate is accelerated. Then the air flow hits the first fan blade 41 and the second fan blade 42, so that the first fan blade 41 and the second fan blade 42 can rotate. Since the inclination angle of the first fan blade 41 is greater than the inclination angle of the second fan blade 42, the staggered arrangement of the fan blades with different inclination angles can change the pressure of the air flow, so that the filter 43 is subjected to different wind pressures. The filter 43 is elastically arranged so that the filter 43 can vibrate, so that the dust filtered on the surface of the filter 43 is shaken off, thereby preventing the dust from clogging the filter 43 and greatly improving the filtering effect. The dust falls into the gap between the conical seat 39 and the connecting pipe 38 for collection, and the connecting pipe 38 can be taken out through the threaded connection pipe 38, which is convenient for subsequent centralized processing. At the same time, a downwardly cross-arranged baffle is provided at the gap between the conical seat 39 and the connecting pipe 38 to prevent the collected dust from being sucked out, thereby further improving the collection effect.

[0039] For further reference, Figure 9 An arc-shaped disk 44 with an upward inclined arc shape is fixedly installed on the outer surface of the connecting pipe 38. Through the use of the first fan blade 41 and the second fan blade 42, the airflow blowing vertically to the activated carbon plate 45 can be dispersed outward. Through the use of the arc-shaped disk 44, the airflow is guided upward, so that the wind pressure on the activated carbon plate 45 is reduced. The low-speed airflow may enable the activated carbon to fully adsorb pollutants, thereby greatly improving the adsorption and purification effect.

[0040] For further reference, Figure 7 、 Figure 11 and Figure 12 The activated carbon plate 45 has a plurality of hexagonal filter holes 46 inside, and a sphere 47 is rotatably installed inside the filter hole 46. When in use, the airflow blowing toward the activated carbon plate 45 enters the filter hole 46 for adsorption. When the airflow hits the sphere 47, the sphere 47 rotates, which can further disperse the airflow, allowing the airflow to stay in the filter hole 46 for a longer time, thereby increasing the contact area with the activated carbon plate and further improving the use effect.

[0041] Example 3: A hazardous chemicals intelligent management device, based on the first and second embodiments, is further implemented. Figure 5 A fire extinguishing box 51 is fixedly installed inside the storage cabinet 10 and on the square of the hollow plate 32. A smoke detector 52 is fixedly installed on the lower surface of the fire extinguishing box 51. A plurality of fire extinguishing nozzles 53 are provided on the lower surface of the fire extinguishing box 51. When in use, when the smoke detector 52 detects a fire inside the storage cabinet 10, the fire extinguishing nozzle 53 is controlled to spray carbon dioxide to extinguish the fire. The fire can be extinguished in time to avoid greater losses, while improving safety and greatly improving the use effect.

[0042] For further reference, Figure 2 and Figure 5 A water tank 56 is fixedly installed on the back side of the storage cabinet 10, and an electromagnetic pump 57 is fixedly installed on the top of the water tank 56. The top of the electromagnetic pump 57 is connected to a conduit 58. A circular sprinkler pipe 54 connected to the conduit 58 is fixedly installed inside the storage cabinet 10, and a plurality of sprinkler heads 55 are provided on the lower surface of the sprinkler pipe 54. When in use, when the smoke sensor 52 detects a fire inside the storage cabinet 10, the electromagnetic pump 57 works through the sprinkler head 55 to spray the interior of the storage cabinet 10 to extinguish the fire, which is carried out simultaneously with the carbon dioxide fire extinguishing, greatly improving the fire extinguishing effect. A collection box 59 is provided in the middle of the support leg 11 for collecting water for fire extinguishing.

[0043] For further reference, Figure 11 A connecting shaft 48 is fixedly installed on the top of the filter hole 46, and symmetrically arranged cover plates 49 are rotatably installed on both sides of the connecting shaft 48. During ventilation, the airflow lifts the connecting shaft 48 from both sides and disperses it from the gap. When extinguishing a fire, the motor 33 receives a signal through the sensor and stops rotating. At this time, the connecting shaft 48 is no longer impacted by the airflow, so that the connecting shaft 48 seals the filter hole 46, closing the air circulation inside the storage cabinet 10, so that when the fire extinguishing nozzle 53 sprays carbon dioxide to extinguish the fire, the sealed environment inside the storage cabinet 10 is maintained, thereby improving the fire extinguishing effect.

[0044] Working principle: When working, the user is located in front of the face recognition module 14, and the face recognition module 14 identifies the user's identity. After successful identification, the cabinet door 12 is opened to take in and put in hazardous chemicals. The user takes out the hazardous chemical bottle and scans the identity code on the bottle through the barcode scanner 15. The scan result is displayed on the control panel 13 and the registration time is performed. After scanning, the hazardous chemical bottle is placed on the upper surface of the weighing tray 16 for weighing. The control panel 13 also records the weight. When the hazardous chemical bottle is put back, it needs to be scanned and weighed again. The control panel 13 records the time and weight of the return. The use record of hazardous chemicals can also be retrieved and viewed at any time through the control panel 13; The hazardous chemical bottle is placed from the top of the installation tube 20, driving the support 26 to slide downward and compressing the spring 25 and the pressure sensor 24. When the pressure sensor 24 is squeezed, a signal is transmitted to the control panel 13, indicating that the hazardous chemical bottle is placed. As the support 26 moves downward, the pressing block 30 rotates downward, thereby driving the clamping block 31 to move inward, fixing the hazardous chemical bottle. When the exhaust fan blades 35 rotate, they discharge the air inside the storage cabinet 10 and cooperate with the air inlet pipe 60 to complete the ventilation of the storage cabinet 10 and adjust the temperature and humidity. Since the conical seat 39 is set in a conical shape, the air flow rate is accelerated. Then the air flow hits the first blade 41 and the second blade 42, so that the first blade 41 and the second blade 42 can rotate. Since the inclination angle of the first blade 41 is greater than the inclination angle of the second blade 42, the staggered arrangement of the blades with different inclination angles can change the pressure of the air flow, so that the filter 43 is impacted by different wind pressures. Because the filter 43 is elastic, it can vibrate, so that the dust filtered on the surface of the filter 43 is shaken off. The use of the first and second blades 41, 42 can disperse the airflow blowing vertically toward the activated carbon plate 45 outward, and the use of the arc-shaped disk 44 can guide the airflow upward, thereby reducing the wind pressure on the activated carbon plate 45. The low-speed airflow can enable the activated carbon to fully adsorb pollutants. When the airflow hits the sphere 47, the sphere 47 rotates, which can further disperse the airflow, allowing the airflow to stay in the filter hole 46 for a longer time and increase the contact area with the activated carbon plate, further improving the use effect. The use of the connecting shaft 48 and the filter hole 46 maintains a sealed environment inside the storage cabinet 10 during fire extinguishing, thereby improving the fire extinguishing effect.

[0045] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
