Description

Technical Field

[0001] This utility model belongs to the field of air filter technology, specifically relating to laboratory air filters. Background Technology

[0002] In laboratory environments, air quality has a crucial impact on the accuracy of experimental results, the normal operation of experimental equipment, and the health of laboratory personnel. In recent years, with the increasing frequency and depth of scientific research activities, the types of chemical experiments involved in laboratories have increased, and the scale of biological research has expanded, making laboratory air pollution a more prominent problem. Existing laboratory air filters primarily address the purification of harmful substances in laboratory air. However, laboratory air is not always in a harmful state. When the concentration of harmful substances in the air is relatively low or absent, manual judgment is needed to determine whether to use the air filter. Some people, for convenience, leave the filter running all day, resulting in unnecessary energy waste. Therefore, this invention provides a purifier that can automatically detect the concentration of harmful substances in the environment and automatically control the fan frequency based on the detection data, making it more energy-efficient and environmentally friendly.

[0027] Example 1:

[0028] like Figure 1-5As shown, a laboratory air filter includes a housing 1, a partition 27 in the middle of the housing 1, a filter section 3 above the partition 27, a particulate filter 6 mounted on the surface of the partition 27, a first activated carbon filter 7 mounted on the left side of the particulate filter 6, a second activated carbon filter 8 mounted on the left side of the first activated carbon filter 7, and a UV lamp 23 fixedly mounted on the top of the first activated carbon filter 7 and the second activated carbon filter 8. A first fan 9 is mounted on the upper surface of the partition 27 and is connected to an air outlet 10. A sensor module 15 is provided on the inner wall of the housing 1, and a relay 12, a frequency converter 13, and a controller 14 are also provided on the inner wall of the housing 1.

[0029] Furthermore, the housing 1 is provided with a first door 2, and a magnetic door switch 11 is installed on the first door 2 and the partition 27.

[0030] A dust removal section 4 is provided below the partition 27. The dust removal section 4 includes a second fan 21 installed at the bottom of the housing 1. The second fan 21 is connected to the filter plate 19. A storage box 20 is provided on the right side of the filter plate 19. A baffle 18 is provided on the right side of the storage box 20. The baffle 18 is connected to one end of the connecting pipe 17. The other end of the connecting pipe 17 is connected to the dust collection port 16. The dust collection port 16 is located on the partition 27.

[0031] Furthermore, a pre-filter 5 is provided on the housing 1, which is located to the right of the particulate filter 6.

[0032] An operation panel 24 is further installed on the housing 1.

[0033] A second door 25 is installed on the side of the housing 1 opposite to the first door 2.

[0034] Furthermore, the housing 1 is provided with a vent 26, which is located on the same side as the air outlet 10 and corresponds to the position of the dust removal part 4.

[0035] Furthermore, the partition 27 is provided with a protrusion 22.

[0036] like Figures 1-5As shown, the working principle of this device is as follows: the operator operates the control panel 24 to run the equipment. The first fan 9 draws air from the laboratory into the device. The air enters through the pre-filter 5, which filters out large debris such as hair. Then it passes through the particulate filter 6, which uses a HEPA filter to effectively filter particles larger than 1 micrometer in diameter and common dust. Next, it passes through the first activated carbon filter 7 and the second activated carbon filter 8 for physical adsorption, filtering out harmful chemicals such as formaldehyde and benzene. The ultraviolet lamp 23 kills bacteria and microorganisms in the air. Finally, the purified air is discharged outdoors through the air outlet 10. During the filtration process, the sensor module 15 monitors the concentration of harmful substances and particulate matter in the laboratory air in real time. The controller 14 controls the speed of the first fan 9 through the frequency converter 13 based on the detection data. The speed increases when the concentration is high and decreases when the concentration is low.

[0037] When staff need to inspect the inside of the equipment, they open the first door 2. Because the first door 2 is connected to a magnetic door switch 11, the equipment will automatically stop operating after the first door 2 is opened, ensuring the safety of the staff.

[0038] The equipment is equipped with a dust removal section 4. When the equipment has been used for a long time, the accumulation of particulate matter and dust in the internal filter will affect the operation of the equipment. At this time, the operator can operate the control panel 24 to turn on the dust removal mode and start the second fan 21 to suck the particles and dust inside the equipment into the storage box 20. After cleaning, the storage box 20 can be taken out and cleaned.

[0039] The above are merely embodiments of this utility model.
