Description

Technical Field

[0001] This utility model relates to the technical field of laboratory exhaust gas emission equipment, and in particular to a concealed exhaust gas emission equipment for laboratories. Background Technology

[0002] Currently, laboratory exhaust gas control technologies are relatively lacking. Common methods for treating laboratory exhaust gases involve using ventilation hoods and exhaust fans to discharge them outdoors, where they are diluted by the air before being released. While this method is effective in ensuring indoor air quality and protecting the health and safety of laboratory personnel, it also pollutes the surrounding atmosphere, directly impacting ambient air quality. To prevent laboratory exhaust gases from polluting the environment, existing technologies typically employ adsorption to treat harmful gases before releasing them.

[0003] However, due to limited space in laboratories, exhaust pipes and equipment are usually installed inside the walls to form concealed exhaust systems. Adsorption units used to adsorb harmful substances are also installed inside the walls. Since the adsorption units need to be replaced after a period of use, the fact that they are installed inside the walls makes the replacement process very inconvenient.

[0004] Therefore, existing laboratory exhaust gas emission devices suffer from the technical problem of inconvenient replacement of adsorption units. Summary of the Invention

[0005] This utility model provides a concealed exhaust gas emission device for laboratories, which solves the technical problem of inconvenient replacement of adsorption units in existing laboratory exhaust gas emission devices.

[0007] A concealed exhaust gas emission device for a laboratory, including an exhaust duct;

[0008] A fan is installed inside the exhaust duct, and the fan introduces gas from the laboratory into the exhaust duct;

[0012] The mounting plate is provided with a through hole, which communicates with the mounting groove. The gas adsorbed by the adsorption block enters the fan through the through hole.

[0013] Preferably, the filter assembly further includes a filter disc with evenly distributed filter holes for gas to pass through, and the filter disc is disposed in the insert.

[0036] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0037] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0038] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] Reference Figures 1 to 6 As shown, a concealed exhaust gas emission device for a laboratory includes an exhaust pipe 1;

[0040] Fan 2 is installed inside the exhaust pipe 1, and the fan 2 introduces gas from the laboratory into the exhaust pipe 1;

[0041] A filter assembly 3 is installed in the exhaust pipe 1, and the gas in the laboratory enters the exhaust pipe 1 through the filter assembly 3.

[0042] and adsorption block 31, wherein the adsorption block 31 is installed on the filter assembly 3;

[0043] The filter assembly 3 is inserted into the exhaust pipe 1, the fan 2 is provided with a plug 21, the filter assembly 3 includes a plug cylinder 32 that cooperates with the plug 21, the filter assembly 3 also includes a mounting plate 321 installed on the plug cylinder 32, the mounting plate 321 is provided with a mounting groove 322 for installing the adsorption block 31, the adsorption block is snapped into the mounting groove 322, and each mounting plate 321 is provided with at least two mounting grooves 322;

[0044] The mounting plate 321 is provided with a through hole 323, which communicates with the mounting groove 322. The gas adsorbed by the adsorption block 31 enters the fan 2 through the through hole 323.

[0045] Specifically, the insert 32 is slidably connected to the insert post 21, which is similar to a track, and the insert 32 slides along the track formed by the insert post 21.

[0046] In some embodiments, the filter assembly 3 is typically installed at the air inlet of the exhaust duct 1, making the filter assembly 3 easy to maintain. The fan 2 is typically installed deep within the exhaust duct 1. Since the fan 2 is not easily damaged and does not require frequent maintenance, the fan 2 can be located deep within the exhaust duct 1, i.e., away from the air inlet.

[0047] In some embodiments, the gas filtered by the filter assembly 3 is then adsorbed by the adsorption block 31, and finally enters the fan 2, which then transports it to the target location through the exhaust pipe 1. The gas in contact with the fan 2 has a high quality and contains fewer harmful substances and dust, thus making the fan 2 less prone to damage.

[0048] In some embodiments, the adsorption block 31 may be made of activated carbon. Alternatively, the adsorption block 31 may also be made of other materials with adsorption capacity.

[0049] Reference Figures 1 to 6 As shown, in some embodiments, the filter assembly 3 further includes a filter disk 33, which is evenly distributed with filter holes 331 for gas to pass through, and the filter disk 33 is disposed on the insert 32.

[0050] In some embodiments, the filter disc 33 should have a certain rigidity and higher strength than the filter screen to bear the force exerted on the filter disc 33 by the adsorption block 31, the mounting disc 321 and the insert 32.

[0051] In some embodiments, the filter disc 33 and the insert 32 are an integral structure, and the filter disc 33 is fixed to the exhaust pipe 1 by screws.

[0052] In some embodiments, the mounting plate 321 is fixed to the insert 32 by threads, or the mounting plate 321 is welded to the insert 32, or the mounting plate 321 and the insert 32 are an integral structure.

[0053] In some embodiments, a sealing gasket is provided between the mounting plate 321 and the inner wall of the exhaust pipe 1, and the sealing gasket is adhered to the mounting plate 321.

[0054] The sealing gasket is used to seal the gap between the mounting plate 321 and the inner wall of the exhaust pipe 1 to prevent the gas in the exhaust pipe 1 from entering the fan 2 directly without being adsorbed by the adsorption block 31.

[0055] Reference Figures 1 to 6 As shown, in some embodiments, the sealing gasket may be made of rubber. The sealing gasket should be in surface contact with the inner wall of the exhaust pipe 1 to increase the sealing area and prevent gas from entering the fan 2 without being adsorbed by the adsorption block 31.

[0056] In some embodiments, the fan 2 includes a housing, the insertion post 21 is integral with the housing, and the end of the insertion post 21 away from the housing contacts the filter disc 33.

[0057] The outer casing can be threaded into the exhaust pipe 1. For example, the outer casing can be fixed into the exhaust pipe 1 with screws. The exhaust pipe 1 can be provided with holes.

[0058] In some embodiments, a sealing layer may be provided between the screws securing the fan 2 and the hole. The sealing layer may be formed using adhesive.

[0059] Reference Figures 1 to 6 As shown, in some embodiments, the cross-sectional shape of the insertion post 21 is polygonal, or the cross-sectional shape of the insertion post 21 is circular.

[0060] In some embodiments, the cross-sectional shape of the insertion post 21 is preferably polygonal. Since polygons have higher bending strength, when the cross-sectional shape of the insertion post 21 is polygonal, the insertion post 21 is less prone to bending during long-term use, thereby extending the service life of the insertion post 21.

[0061] In some embodiments, the filter disc 33 is coaxially arranged with the insert 32, and the filter disc 33 closes the end of the insert 32 near the filter disc 33.

[0062] In some embodiments, a partition 324 is provided between two adjacent mounting slots 322 of the same mounting plate 321. The partition 324 and the mounting plate 321 are integrally formed. The partition 324 is provided with a snap-fit ​​portion for snapping the adsorption block 31.

[0063] In some embodiments, the snap-fit ​​portion is a damping layer disposed on the partition 324, or the snap-fit ​​portion is an elastic protrusion protruding from the partition 324.

[0064] Reference Figures 1 to 6 As shown, in some embodiments, the elastic protrusion can be fixed to the partition 324 by adhesive bonding.

[0065] In some embodiments, when the installation position of the fan 2 is far from the filter disc 33, i.e., when the insertion post 21 is not suitable to be installed on the outer casing of the fan 2, the insertion post 21 can be fixed inside the exhaust pipe 1. For example, the insertion post 21 can be fixed inside the exhaust pipe 1 using a mounting bracket.

[0066] The mounting bracket can be made of rods. The mounting bracket can be fixed inside the exhaust pipe 1 in any way, such as by threaded connection or welding.

[0067] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0068] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
