Description

Technical Field

[0001] The utility model relates to a high efficiency filter for laboratory air, belonging to the technical field of air filters. Background Art

[0002] A biosafety laboratory, also known as a biological laboratory, is a place where experiments related to biology are conducted. Existing biological laboratories are usually for learning and research. When conducting experimental research in a biological laboratory, air filters are usually required to capture dust and harmful substances from the gas-solid two-phase flow to purify the gas. The purified air is then sent indoors to ensure a clean laboratory.

[0003] However, the existing filters are generally dry filters, which only install filter elements such as filter cotton or sponge inside the filter to filter out dust in the air. This dry filter element is prone to clogging after filtering for a period of time, and the air filtration is not complete, and a small amount of dust will still be blown into the laboratory. In view of the above shortcomings, the utility model proposes a laboratory air high-efficiency filter. Utility Model Content

A plurality of L-shaped flat pipes 24 are connected to the bottom surface of the air inlet pipe body 21 at intervals.

[0024] The filter box group 3 includes a filter water box 31, and the upper right end of the filter water box 31 is connected to a water inlet pipe 32, and the lower right end of the filter water box 31 is connected to a drain pipe 33. The lower end of the rear side of the filter water box 31 is spaced apart and provided with multiple air inlets 34 that are connected to each L-shaped flat tube 24 one by one.

[0025] The first water filter element 4 includes a sleeve 41, and a mesh plate 42 is provided at the lower end of the sleeve 41 cavity, and a plurality of carrying handles 43 are provided around the sleeve 41. A plurality of water filter balls 44 are placed on the top surface of the mesh plate 42. The first water filter element 4 has the same structure as the second water filter element 5, but water filter cotton is placed on the mesh plate of the second water filter element 5.

[0026] The lifting cover assembly 6 includes two slide rails 61 , and sliders 62 are movably mounted on the two slide rails 61 . A lifting frame 63 is horizontally connected between the two sliders 62 , and a cover 64 is disposed in the middle of the lifting frame 63 .

[0027] The air outlet pipe group 7 includes an air outlet pipe body 71, and the air outlet pipe body 71 is an L-shaped pipe, and a second fan 72 is provided in the lower end cavity of the air outlet pipe body 71. The lower end of the air outlet pipe body 71 is connected to a telescopic air pipe 73, and the lower end of the telescopic air pipe 73 is connected to the upper end of the cover 64.

[0028] Working principle:

[0029] First, add water to the filtered water tank 31, and the water level should be 4-5 cm higher than each air inlet 34. Then turn on the first fan 22 and the second fan 72. At this time, the external air will be sucked in from the right end of the air inlet pipe body 21. When passing through each guide inclined plate 23, it will be guided downward into each L-shaped flat tube 24, and flow out from each air inlet 34 to mix with the water in the filtered water tank 31 to filter out dust and harmful substances in the air. At this time, the second fan 72 starts to form an upward suction force on the filtered water tank 31, so that the filtered air first flows upward into the various water filter balls 44 in the first water filter element 4 to absorb the moisture in the air, and then passes upward through the water filter cotton in the second water filter element 5 to absorb the final moisture. Finally, the completely filtered air flows into the laboratory from the air outlet pipe body 71 to achieve the purpose of high-efficiency filtration.

[0030] When the water filter ball 44 and the water filter cotton need to be replaced, the two sliders 62 slide upward on the two slide rails 61 synchronously, so that the cover 64 moves up. At this time, the telescopic air duct 73 will retract, so that the upper end of the second water filter element 5 opens a gap. At this time, the second water filter element 5 and the first water filter element 4 can be removed through the replacement port for replacement.
