Description

Technical Field

[0001] The present invention relates to the technical field of biological experiments, and particularly to an air purification system and method for a biological laboratory. Background Art

[0002] Biological experiments refer to a series of scientific experiments carried out in the field of biology. These experiments aim to study various characteristics, processes, and phenomena of organisms. Biological experiments cover a wide range of fields, including molecular biology, cell biology, physiology, and genetics, etc. An air purification system is a technical device designed to remove or adsorb various pollutants in the input air, making the air clean. Its functions include removing harmful pollutants to the human body, such as bacteria and pollen, filtering out floating smoke and particulate impurities in the air, and killing bacteria and viruses in the air.

[0003] After retrieval, in the prior art, the patent application number is CN202123288927.4, which discloses an air purification device for a biological laboratory. Through the symmetrical negative pressure adsorption purification of the purification component, under the rotary support of the rotatable and adjustable support component, it can rotate and negatively pressure adsorb and purify the indoor air. It can not only improve the efficiency of indoor air purification, but also ensure the comprehensiveness of indoor air purification. And during the purification process, through the guiding engagement of the purification mechanism and the purification cylinder, it is convenient for the staff to carry out regular disassembly and cleaning.

[0004] The above technical solution still has the following defects: Since the odors or toxic gases generated in a biological laboratory do not always float at the same height, some odors or toxic gases will float upwards. This air purification device can only adsorb and purify the odors or toxic gases at a specified height, so the purification of the indoor air is not comprehensive enough. And during the purification process, a lot of dust is easily attached to the surface of the air outlet duct, resulting in the blockage of the air outlet structure and seriously affecting the air purification efficiency.

[0024] As a further description of the above technical solution:

[0025] A method for purifying air in a biological laboratory. After the intake fan is turned on, external gas will be sucked into the box body. At this time, the gas will pass through the filter plate, purification plate and activated carbon adsorption plate in sequence, and then be discharged from the dust-proof general net. During this process, the peculiar smell or toxic gas in the air will be adsorbed and purified. After the forward and reverse motor is turned on, the small gear will drive the large gear at the other end of the inner wall of the gear belt to rotate slowly. At this time, the air purification mechanism above the table board will also rotate together, so as to purify the air around. After the cylinder is turned on, the gear rod during the up and down movement can drive the gear disk to rotate together. At the same time, the first bevel gear, the second bevel gear, the shaft core, the small end face gear, the large end face gear and the threaded column will rotate in sequence. When the threaded column rotates, the slider will drive the air purification mechanism to move up and down together, so as to purify the air at different heights.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] (1) When the cylinder drives the gear rod to move up and down together, the gear rod can drive the gear disk to rotate quickly. At this time, the first bevel gear at the top of the gear disk can drive the second bevel gear and the shaft core in the rotating ring to rotate together. At the same time, the small end face gear on the other end face of the shaft core will also drive the large end face gear and the threaded column to rotate together. Subsequently, the slider can move up and down on the outer wall of the rotating threaded column. At the same time, the air purification mechanism installed at the front end of the slider will also move up and down together, so as to play a role in adjusting the height of the air purification device. It can not only adsorb and purify the peculiar smell or toxic gas at high places, but also greatly improve the air purification effect of the whole device.

[0028] (2) By setting a simple connection method between the universal wheels and the base, the disassembly and assembly steps of the universal wheels are more convenient and fast. The gear belt can be used to connect the small gear and the large gear in series. At this time, the rotation of the small gear can drive the large gear to rotate together. When the large gear rotates, the air purification mechanism above the table board will also rotate together, so as to facilitate the purification of the air around.

[0029] (3) The staff can push and pull the filter plate, purification plate and activated carbon adsorption plate by using the baffle. When the filter plate, purification plate and activated carbon adsorption plate are pulled outwards, the outer walls on both sides of the filter plate, purification plate and activated carbon adsorption plate will slide along the opposite surfaces of the cleaning brushes. At this time, the cleaning brushes can remove the dust, impurities or fluff attached to the surfaces of the filter plate, purification plate and activated carbon adsorption plate, so as to prevent the filter plate, purification plate and activated carbon adsorption plate from being blocked.

[0030] (4) After the bolts are removed, the square retaining ring and the front plate can be taken off. At this time, the staff can clean the inside of the box. By setting a simple connection method between the intake fan and the mounting ring, the disassembly, repair, and cleaning steps of the intake fan are made more convenient and rapid.

When the bolts 54 are removed, the square retaining ring 55 and the front plate 41 can be taken off. At this time, the staff can clean the inside of the box body 36. A dust-proof ventilation net 56 penetrates through the center of the front plate 41. By providing the dust-proof ventilation net 56, it mainly plays a role in exhausting air. On both outer walls of the hollow frame 28, sliding frames 57 are welded. One end of the inner wall of each sliding frame 57 is slidably connected to the outer wall of the sliding strip 37. By providing the connection structure between the sliding frame 57 and the sliding strip 37, the up and down movement of the air purification mechanism is made more stable.
