Description
Technical Field
[0001] The present invention relates to the technical field of chemical storage, and in particular to a safety storage cabinet for hazardous chemicals. Background Art
[0002] Hazardous chemicals are widely used in many fields, including chemical industry, scientific research, and medicine. These chemicals include flammable and explosive materials, corrosive substances, highly toxic substances, and various oxidants. They play an irreplaceable role in promoting industrial development, promoting scientific research, and protecting medical health. However, the potential hazards of hazardous chemicals themselves, such as flammability, explosiveness, corrosiveness, and toxicity, make their safe storage a crucial link. If stored improperly, it may not only cause the quality of the chemicals themselves to be damaged, but also cause serious accidents such as fires, explosions, and poisoning, posing a huge threat to the safety of people's lives, property safety, and the environment. In the existing technology, for safety reasons, hazardous chemicals are usually stored in storage cabinets. However, existing hazardous chemical storage cabinets usually adopt a unified temperature and humidity control method, or do not have temperature and humidity adjustment functions at all. As a result, in actual use, staff have to store chemicals with different temperature and humidity requirements separately, which not only takes up a lot of space but also increases management costs. Summary of the Invention
[0003] The purpose of the present invention is to provide a safe storage cabinet for hazardous chemicals, which can conveniently store chemicals with different temperature requirements, and can also conveniently and automatically adjust the temperature and humidity, saving storage control and reducing management costs.

At the same time, the gas in each space can enter the connecting pipe and be discharged through the first exhaust pipe, thereby preventing the gas emitted by different chemicals from accumulating in the different spaces and interacting with each other to produce dangerous chemical reactions.

[0015] In summary, the present invention has the following beneficial effects: First, it can facilitate the storage of chemicals with different temperature and humidity requirements. The storage tray can be used to divide the storage cavity into multiple spaces. The rubber ring can increase the fit between the storage tray and the cabinet, thereby improving airtightness and making each space a sealed space. Chemicals with different temperature and humidity requirements can be stored in different spaces as needed. The grid plate and support column can be used to collect leaked chemicals in the storage tray. Secondly, it can conveniently adjust the storage temperature and humidity. The first fan can extract the finished gas, the heating resistor can heat the gas, the humidifier can humidify the gas, the semiconductor refrigeration sheet can cool the gas, the temperature sensor and the humidity sensor can monitor the temperature of the storage space, and the single-chip computer can conveniently control the power on and off of the electromagnet, thereby controlling the rotation of the impeller. The gas entering the first adjustment shell through the first guide pipe can drive the impeller to rotate, thereby allowing the second guide pipe to enter the corresponding storage space, and discharge the heated, humidified or cooled gas into the corresponding storage space, thereby adjusting the temperature and humidity of the storage space. Third, the second fan can be used to conveniently extract the gas in the storage space, so that the gas leaked from the chemicals can be extracted and discharged from the cabinet. At the same time, the temperature and humidity in the storage space can be quickly adjusted in conjunction with the flow limiting mechanism. The harmful substances in the extracted gas can be absorbed through the filter element. At the same time, when the extracted gas is discharged from the cabinet, it needs to pass through the heat dissipation pipe. Since the semiconductor refrigeration chip is started, the hot end absorbs the heat generated by the semiconductor refrigeration chip. The extracted gas can conveniently cool down and dissipate the heat at the hot end. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Instructions for use: When in use, pull the handle 9 to open the cabinet door 6, install the storage tray 11 on the support bar 10 in the storage chamber 2 through the storage opening 5, and divide the storage chamber 2 into multiple storage spaces. The airtightness between different spaces is increased by the sealing ring, and different chemicals are classified and placed on the grid plates 13 on different layers according to the temperature and humidity conditions required for storage. The support columns 14 on the grid plates 13 are used to form a certain space between the grid plates 13 and the storage tray 11, so that when the required drugs leak, they will enter the storage tray 11 through the grid plates 13 for collection, thereby preventing the chemicals from falling into different spaces. Then, rotate the cabinet door 6 to attract the first magnetic strip 7 and the second magnetic strip 8, close the cabinet door 6, and then use the control button 56 on the console 54 to set the temperature and humidity required for storage in each space. The temperature of each space is monitored by the temperature sensor 52 and the humidity sensor 53. The temperature and humidity changes in each space can be conveniently observed through the display screen 55.
[0030] Connect the power cord 57 to the power supply, and control the start of the first fan 16 in the air inlet pipe 15 through the control button 56 on the console 54 to extract the external gas. The gas enters the air inlet pipe 15, and then passes through the diverter pipe 17. The gas enters the heating pipe 18 through the diverter pipe 17. By energizing the heating resistor 19 in the heating pipe 18, the heating resistor 19 heats the gas entering the heating pipe 18. The gas enters the humidifying pipe 20 through the diverter pipe 17, and the humidifier 21 is started. A humidified airflow is generated by the humidifier 21, and then enters the humidifying pipe 20 through the drainage pipe 22 to humidify the gas in the humidifying pipe 20. After the gas enters the refrigeration pipe 25 through the diverter pipe 17, the gas is cooled by the semiconductor refrigeration plate 26 in the refrigeration pipe 25, and then the processed gas enters the corresponding first guide pipe 29.
[0031] The temperature and humidity of different spaces are monitored by the temperature sensor 52 and the humidity sensor 53. However, when the temperature and humidity are lower than or higher than the set value, the single chip microcomputer 51 in the guide chamber 3 controls the electromagnet 40 in the limit slot 32 to be energized and de-energized. When the electromagnet 40 is energized, the electromagnet 40 and the magnetic block 39 generate a repulsive force, pushing the slider 37 to drive the pawl block 36 to clamp the ratchet 35, so that after the airflow enters the first adjustment shell 30, it cannot drive the impeller 33 to rotate. When the electromagnet 40 is de-energized, the gas enters the first adjustment shell 30, driving the impeller 33 to rotate, the impeller 33 drives the rotating shaft 34 to rotate, and the rotating shaft 34 drives the ratchet 35 to rotate, pushing the pawl block 36 to drive the slider 37 to slide, compressing the spring 38. The spring 38 generates an elastic force, which enables the pawl block 36 to always cooperate with the ratchet 35, thereby controlling the electromagnet 40 that needs to be de-energized to be de-energized, allowing the required gas to enter the second The impeller 33 in the adjustment shell is driven to rotate, thereby entering the space where the temperature and humidity need to be changed through the second guide pipe 41, so as to change the temperature and humidity in different spaces and control the temperature and humidity of different chemicals. At the same time, the second fan 48 in the exhaust pipe is started, and the second fan 48 extracts the gas in each space through the connecting pipe 42 and the first exhaust pipe 43. The start of the current limiting mechanism can quickly adjust the temperature and humidity in each space, and at the same time, it can extract the gas in each space to prevent the accumulation of gas leaked from chemicals from causing dangerous reactions. The extracted gas passes through the filter tube 45, and the harmful components in the gas are absorbed and filtered by the filter element 46 in the filter tube 45, and then enters the heat dissipation pipe 27 through the second exhaust pipe 49, which can dissipate heat and cool the heat generated by the hot end 28 due to the operation of the semiconductor refrigeration plate 26, and finally is discharged from the cabinet 1 through the third exhaust pipe 50.
[0032] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
