Description

Technical Field

[0001] This utility model relates to the technical field of air filtration devices, specifically an animal laboratory ventilation device with a disinfection structure. Background Technology

[0002] The ventilation and disinfection system in animal laboratories is one of the core systems for ensuring the health of laboratory animals, the safety of personnel (biosafety), environmental safety, and the reliability of experimental results. It mainly solves two key problems: air replacement (ventilation) and air purification / disinfection. The commonly used combination in existing animal laboratory ventilation and disinfection systems is as follows: pre-filter -> medium-efficiency filter -> activated carbon filter -> UV lamp segment -> HEPA filter. Among them, the UV lamp segment uses ultraviolet light of a specific wavelength to destroy the DNA / RNA of microorganisms, thereby inactivating them and killing viruses, bacteria, fungi, and other microorganisms in the air, thus disinfecting the air passing through the irradiated area.

[0003] In practical use, when using UV lamps to disinfect air, the air needs to be fully exposed to UV light of sufficient intensity for a sufficient time, and dead zones should be avoided to achieve a good disinfection effect. Based on this, in order to achieve efficient and thorough disinfection of air by UV lamps, an animal laboratory ventilation device with a disinfection structure is provided. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 In this embodiment of the utility model, the animal laboratory ventilation device with disinfection structure includes a filter box 1. The inner side of the filter box 1 is sequentially installed with a primary filter 2, a medium-efficiency filter 3, an activated carbon filter 4, an air disinfection component 5, and a HEPA filter 6 along the air inlet direction. The air disinfection component 5 includes an air guide unit, a UV lamp 507, and a disassembly unit.

[0032] The disassembly unit is used to enable a detachable connection between the UV lamp 507 and the air guide unit;

[0033] The air guide unit is used to guide the airflow, enabling the UV lamp 507 to disinfect the air without dead angles.

[0034] The air guiding unit includes a front end plate 501, a side-inverted P-shaped duct 502, a rear end plate 503, a vertical baffle 504, an inclined partition 505, and an air outlet 506.

[0035] The side-inverted P-type pipe 502 is fixed between the front end plate 501 and the rear end plate 503. The air inlet of the side-inverted P-type pipe 502 faces the activated carbon filter 4. The vertical baffle 504 is fixed between the front end plate 501 and the rear end plate 503 and is located at the bottom of the air inlet of the side-inverted P-type pipe 502. The air outlet side of the side-inverted P-type pipe 502 is connected and fixed to the vertical baffle 504.

[0036] Inclined baffles 505 are distributed in the middle area of ​​the side-inverted P-type pipe 502 and one end is fixedly connected to the rear end plate 503. The other end of the inclined baffles 505 does not contact the front end plate 501, and the inclined baffles 505 are fixedly connected to the inner wall of the side-inverted P-type pipe 502, which is used to divide the middle area of ​​the side-inverted P-type pipe 502 into two "C" shaped channels.

[0037] The air outlet 506 is located on the side of the rear panel 503 near the HEPA filter 6 and is connected to a "C"-shaped channel;

[0038] UV lamps 507 are evenly distributed inside the "P"-shaped channel and two "C"-shaped channels of the side-inverted P-shaped pipe 502. The "P"-shaped channel and two "C"-shaped channels of the side-inverted P-shaped pipe 502 provide guidance for airflow, so as to achieve full contact between air and UV lamps 507.

[0039] Both the side-inverted P-shaped pipe 502 and the inclined partition 505 are made of transparent material.

[0040] In this embodiment: When this device is in use, the filter box 1 is installed in the ventilation system pipeline of the animal laboratory. The air passes through the following in sequence: primary filtration by the pre-filter 2, secondary filtration by the medium-efficiency filter 3, adsorption filtration by the activated carbon filter 4, ultraviolet disinfection by the air disinfection component 5, and fourth filtration by the HEPA filter 6, thereby achieving the air filtration and disinfection operation.

[0041] During the above process, when the air filtered by the carbon filter 4 flows to the air disinfection component 5, it will flow along the duct of the side-inverted P-shaped duct 502 to a "C"-shaped channel in the middle of the side-inverted P-shaped duct 502. Then, it will flow along the trajectory of this "C"-shaped channel to the gap between the inclined baffle 505 and the front end plate 501, and enter the interior of another "C"-shaped channel. It will then flow in the opposite direction to the air outlet 506 and be discharged to the HEPA filter.

[0042] During this process, the air can fully contact multiple UV lamps 507. Since the side-inverted P-shaped pipe 502 and the inclined partition 505 are both made of transparent material, the air can be irradiated by the ultraviolet light of multiple UV lamps 507 during the folding flow, effectively avoiding the occurrence of irradiation dead corners and effectively extending the time for the air to receive ultraviolet light, thus achieving a full and efficient disinfection effect.

[0043] Please refer to this carefully. Figures 1-2 The assembly and disassembly unit includes a solid screw cylinder 508, a plug hole 509, an end plug hole 510, and a fastening nut 511;

[0044] The solid screw barrel 508 is fixed to the front end of the front end plate 501, and the front end plate 501 has a through hole that communicates with the solid screw barrel 508.

The side of the filter box 1 is connected to the limiting pressure plate 7 around the windows by fastening bolts 8. The limiting pressure plate 7 is attached to the side of the pre-filter 2, medium-efficiency filter 3, activated carbon filter 4, air disinfection assembly 5, and HEPA filter 6 and is tightened by fastening bolts 8 to fix the pre-filter 2, medium-efficiency filter 3, activated carbon filter 4, air disinfection assembly 5, and HEPA filter 6.

[0049] In this embodiment, it should be noted that: the fastening bolt 8 is threadedly connected to the side plate of the filter box 1, and the limiting pressure plate 7 is sleeved on the outside of the screw of the fastening bolt 8.
