Description

Technical Field

[0001] This utility model relates to the field of air purification device technology, and more specifically, to a laboratory air purification device. Background Technology

[0002] In modern scientific research, laboratories serve as core locations, and the air quality within them directly impacts the accuracy of experimental results, the health of researchers, and the normal operation of experimental equipment. During experiments, laboratories frequently generate various pollutants, such as harmful gases (formaldehyde, benzene compounds, nitrogen oxides, etc.) from chemical experiments, microbial aerosols from biological experiments, and dust particles from physical experiments. These pollutants not only interfere with the experimental environment but may also trigger respiratory illnesses, allergic reactions, and even more serious health problems for researchers.

[0003] Currently, common laboratory air purification technologies mainly include filtration, adsorption, photocatalysis, and chemical neutralization. While filtration can effectively remove dust particles, its purification effect on harmful gases and microorganisms is limited. Adsorption technologies (such as activated carbon adsorption) can adsorb some harmful gases, but their adsorption capacity is limited, and they are prone to desorption after adsorption saturation, causing secondary pollution. Photocatalysis can theoretically decompose a variety of pollutants, but in practical applications, its efficiency is limited by factors such as light intensity and catalyst activity, resulting in unstable purification effects. Chemical neutralization is highly targeted, but it is applicable to only a single type of pollutant, and the neutralization reaction may produce new byproducts. In addition, existing laboratory air purification devices are generally located in fixed positions, resulting in low air purification efficiency. Utility Model Content

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of the present invention provides a laboratory air purification device, including a test bench 1 and a purification component 2, wherein the purification component 2 is slidably installed on the side of the test bench 1.

[0024] like Figure 2 As shown, the purification assembly 2 includes a purification body 21, track rollers 22, and an electric track 23. The upper side of the purification body 21 is fixedly installed with the track rollers 22. The track rollers 22 are slidably installed on the outer surface of the electric track 23. The bottom of the purification body 21 is provided with movable rollers 27. The top of the purification body 21 is fixedly installed with a support frame 24. The top of the purification body 21 is fixedly connected with a vent pipe 25. One end of the vent pipe 25 is fixedly connected with an air inlet hood 26. The side of the air inlet hood 26 is fixedly connected to the top of the support frame 24.

[0025] By setting up an electric track 23, the track rollers 22 are controlled to drive the purification body 21 to slide on the side of the electric track 23, thereby moving the purification body 21 to any position on the test bench 1, achieving precise purification of the test bench 1, improving the purification efficiency of the laboratory, and making up for the shortcomings of the long length of the test bench 1 and the fixed position of the purification device, which resulted in low purification efficiency.

[0026] like Figures 3-4As shown, a hinged door 201 is installed on the upper end of the purifier body 21. Fixing brackets 203 are fixedly installed on both sides of the upper end of the purifier body 21. Filter components 3 are embedded in the interior of the fixing brackets 203 on both sides. Air outlets 202 are opened on both sides of the upper end of the purifier body 21. Exhaust fans 205 are fixedly installed on both sides of the interior of the purifier body 21. The exhaust fans 205 are located on the side of the air outlets 202.

[0027] The fixed frame 203 has a limit rail 206 fixedly installed on both sides of the upper and lower ends, and an ultraviolet lamp 207 fixedly installed on both sides of the fixed frame 203. The ultraviolet lamp 207 is located between the limit rails 206 on both sides.

[0028] By setting the interaction between the limiting track 206 and the limiting block 32, it is convenient to disassemble and assemble the filter assembly 3 inside the fixing frame 203, and to replace and clean the filter assembly 3.

[0029] like Figure 5 As shown, the filter assembly 3 includes a filter frame 31, an air filter 34, an activated carbon filter layer 35, and a photocatalytic filter layer 36. Limiting blocks 32 are fixedly installed on both sides of the upper and lower ends of the filter frame 31, and limiting grooves 33 are opened on both the upper and lower ends of the filter frame 31. The air filter 34 is fixedly installed on the left side of the filter frame 31, and the right side of the air filter 34 is fixedly installed with the activated carbon filter layer 35. The photocatalytic filter layer 36 is fixedly installed on the right side of the filter frame 31.

[0030] By setting up an air filter 34, dust and solid particles in the air are filtered out, and odors in the air are removed by an activated carbon filter layer 35. The photocatalytic filter layer 36, in conjunction with the ultraviolet lamp 207, oxidizes and decomposes harmful organic substances, pollutants, odors, bacteria, etc. in the air, such as formaldehyde, methylamine, benzene, xylene, TVOC, etc., into harmless CO2 and H2O, thereby achieving the purpose of purifying the air and decomposing harmful organic substances.

[0031] The limiting block 32 is slidably installed inside the limiting track 206, and the limiting groove 33 is located on the outer surface of the ultraviolet lamp 207, so that the ultraviolet lamp 207 is located between the activated carbon filter layer 35 and the photocatalytic filter layer 36.

[0032] The lower end of the purifier body 21 is fitted with a dust collection box 204, which is located below the fixing frame 203 and below the air filters 34 on both sides.

[0033] The working process of this utility model is as follows:

[0034] In use, the electric track 23 causes the track rollers 22 to move on the outer surface of the electric track 23, and drives the purification body 21 to move on the side of the electric track 23, so that the air inlet hood 26 is moved to the position of the test bench 1 where air filtration is required. The exhaust fan 205 works, so that the air inlet hood 26 filters the air on the top of the test bench 1.

[0035] When the purifier 21 is working, air enters the interior of the purifier 21 through the ventilation pipe 25 and undergoes primary filtration through the air filter 34, which intercepts dust and solid particles and causes them to fall into the dust collection box 204 by gravity. When the primary filtered air passes through the activated carbon filter layer 35, odors are removed through adsorption by the activated carbon filter layer 35. The photocatalytic filter layer 36 oxidizes and decomposes harmful organic compounds, pollutants, odors, and bacteria in the air, such as formaldehyde, methylamine, benzene, xylene, and TVOC, into harmless CO2 and H2O. The ultraviolet lamp 207 intermittently and continuously irradiates the photocatalytic filter layer 36 and the activated carbon filter layer 35 to achieve disinfection, thereby purifying the air, decomposing harmful organic compounds, and improving the disinfection effect of the air.
