[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0024] like Figures 1 to 3 As shown, this utility model embodiment discloses a modular laboratory filtration assembly, including a housing 1, a switching component 2, and a filtration module 3. The housing 1 has a central chamber 101 inside. The housing 1 is provided with a first air duct 4 and a second air duct 5. The filtration module 3 in the first air duct 4 and the filtration module 3 in the second air duct 5 have different properties. The switching component 2 is used to open the first air duct 4 or the second air duct 5, so that the first air duct 4 is connected to the central chamber 101 or the second air duct 5 is connected to the central chamber 101.

[0025] A first air duct 4 and a second air duct 5 are planned inside the housing 1. The first air duct 4 or the second air duct 5 is connected to the central chamber 101. The filter modules 3 installed in the different air ducts have different properties to filter waste gases with different properties of harmful substances. The switching component 2 completes the switching between the first air duct 4 and the second air duct 5, so that a single device can treat waste gases of different properties, thus improving flexibility.

[0026] In some embodiments, the switching assembly 2 is located in the central chamber 101. The switching assembly 2 includes a rotating shaft 21, a partition plate 22 and a support frame 23. The partition plate 22 is connected to the rotating shaft 21 through the support frame 23. The rotation path of the partition plate 22 avoids the inner wall of the adjacent chamber.

[0027] By rotating the rotating shaft 21, the partition plate 22 is rotated so that the first air duct 4 is connected to the central chamber 101, while the second air duct 5 is not connected to the central chamber 101. The filter module 3 in the first air duct 4 purifies the exhaust gas; or the second air duct 5 is connected to the central chamber 101, while the first air duct 4 is not connected to the central chamber 101. The filter module 3 in the second air duct 5 purifies the exhaust gas. The filter modules 3 in the first air duct 4 and the second air duct 5 have different properties, thus achieving the purification of exhaust gases with different properties of harmful substances.

[0028] Furthermore, a filter plate is detachably installed on the support frame 23. The support frame 23 is located in the central chamber 101 of the housing 1. The central chamber 101 is used to connect the first air duct 4 or the second air duct 5. A filter plate, such as an activated carbon filter plate, is added inside the support frame 23. The exhaust gas entering the housing 1 is purified by the superposition of the filter module 3 in the first air duct 4 or the second air duct 5 and the filter plate in the central chamber 101, which further improves the purification effect of the exhaust gas.

[0029] In this invention, the filter module 3 and the packing material inside the filter plate are existing technologies. Different types of filter modules 3 are selected based on the different properties of the harmful substances contained in the exhaust gas, such as acidic gas filter module 3, alkaline gas filter module 3, and organic gas filter module 3. Furthermore, based on the structural characteristics of the filter module 3, it can be placed horizontally, vertically, or at an angle, and adjustments can be made according to the specific circumstances.

[0030] The filter module 3 includes a housing, packing material, and a filter screen. The packing material fills the space formed by the filter screen and the housing. A raised fixing post is provided on the inner wall of the housing. This fixing post ensures that the packing material is fully and evenly distributed, preventing accumulation during rotation or changes in its horizontal position. Alternatively, other existing technologies can be used to achieve the same result.

[0031] Furthermore, a cover plate 11 is detachably installed on the housing 1, and the cover plate 11 and the housing 1 body form a closed chamber.

[0032] The cover plate 11 and the housing 1 are detachably connected, which facilitates the replacement and maintenance of the internal filter module 3, switching component 2, etc. The assembly of the cover plate 11 and the housing 1 can form a closed chamber to ensure the airtightness of the exhaust gas treatment process. The sealing technology can adopt existing technology, which will not be elaborated here. This utility model focuses on the different exhaust gas purification structures formed by the first air duct 4, the second air duct 5, and the switching component 2 inside the housing 1.

[0033] Furthermore, the first air duct 4 is provided with a first chamber 41 and a second chamber 42, and ventilation openings 6 are respectively provided on the first chamber 41 and the second chamber 42. Even further, a filter module 3 of the same nature is detachably installed in both the first chamber 41 and the second chamber 42.

[0034] When the switching component 2 connects the first air duct 4 to the central chamber 101, the second air duct 5 is closed at the same time. The exhaust gas enters from the vent 6 of the first chamber 41, flows through the central chamber 101, enters the second chamber 42, is purified by the filter module 3 in the first chamber 41 and the second chamber 42, and then flows out from the vent 6 of the second chamber 42.

[0035] Furthermore, the second air duct 5 is also provided with a third chamber 51 and a fourth chamber 52, with ventilation openings 6 respectively on the third chamber 51 and the fourth chamber 52. Even further, another filter module 3 of the same nature can be detachably installed in the third chamber 51 and the fourth chamber 52.

[0036] When the switching component 2 connects the second air duct 5 to the central chamber 101, the first air duct 4 is closed at the same time. The exhaust gas enters from the vent 6 of the third chamber 51, flows through the central chamber 101, enters the fourth chamber 52, and is purified by the filter module 3 in the third chamber 51 and the fourth chamber 52 before flowing out from the vent 6 of the fourth chamber 52.

[0037] In some embodiments, the first chamber 41, the second chamber 42, the third chamber 51 and the fourth chamber 52 are respectively provided with slide grooves or slide rails, and the filter module 3 is slidably installed with the slide grooves or slide rails.

[0038] After a certain period of use, different filter modules 3 can be quickly replaced by using a slide rail or chute, making it convenient for personnel to replace them.

[0039] In some embodiments, one end of the rotating shaft 21 extends out of the cover plate 11, and the extended end of the rotating shaft 21 is connected to a handle or drive (not shown in the figure).

[0040] The rotating shaft 21 rotates so that the partition plate 22 blocks the connection between the first air duct 4 and the central chamber 101, or blocks the connection between the second air duct 5 and the central chamber 101. This can be done manually by a handle, or by using a drive component such as a motor to drive the rotating shaft 21 to rotate, thereby automating the exhaust gas treatment.

[0041] In some embodiments, the first chamber 41 and the second chamber 42 are arranged opposite to each other, and the third chamber 51 and the fourth chamber 52 are arranged opposite to each other; or the first chamber 41 and the second chamber 42 are arranged adjacent to each other, and the third chamber 51 and the fourth chamber 52 are arranged adjacent to each other.

[0042] When the first chamber 41 and the second chamber 42 are arranged opposite each other, and the third chamber 51 and the fourth chamber 52 are arranged opposite each other, the first air duct 4 and the second air duct 5 are evenly divided inside the housing 1. The adjacent chambers can be arranged at a 90° interval. When the second air duct 5 is connected to the central chamber 101, the corresponding partition plate 22 is rotated 90°. The partition plate 22 simultaneously blocks the first chamber 41 and the second chamber 42, and the third chamber 51, the fourth chamber 52 and the central chamber 101 are connected.

[0043] Similarly, when the first chamber 41 and the second chamber 42 are arranged adjacent to each other, and the third chamber 51 and the fourth chamber 52 are arranged adjacent to each other, the adjacent chambers can be spaced 90° apart. When the first air duct 4 is connected to the central chamber 101, the corresponding partition plate 22 rotates 180° and the partition plate 22 blocks the third chamber 51 and the fourth chamber 52 at the same time, and the first chamber 41 and the second chamber 42 are connected to the central chamber 101.

[0044] In some embodiments, the housing 1 is further provided with a third air duct, and the switching component 2 is used to switch the first air duct 4, the second air duct 5 or the third air duct, so that the first air duct 4 is connected to the central chamber 101, or the second air duct 5 is connected to the central chamber 101, or the third air duct is connected to the central chamber 101.

[0045] This invention can also add a third air duct, which can evenly divide the housing 1 into three air ducts, increasing the types of exhaust gas that can be treated.

[0046] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
