Description

Technical Field

[0001] This utility model belongs to the field of air duct technology, specifically referring to an air duct with air purification function. Background Technology

[0002] In modern building ventilation systems, ducts serve as crucial channels for air transport, and the air quality inside them directly impacts the indoor environment. However, traditional ducts only perform airflow transport and lack effective air purification capabilities. Dust, odors, harmful gases, and other impurities in the air can easily enter the room with the airflow, adversely affecting human health and the indoor environment.

[0003] When cleaning or replacing filters and adsorption materials in some existing air ducts with purification functions, it is often necessary to disassemble part or even the entire air duct section. This operation is cumbersome, time-consuming, and labor-intensive, which seriously affects the normal operation and maintenance efficiency of the system. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing air ducts with purification functions often require the disassembly of part or even the entire duct section when cleaning or replacing filters and adsorption materials. This is cumbersome, time-consuming, and labor-intensive, seriously affecting the normal operation and maintenance efficiency of the system.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a duct with air purification function, including a duct, one end of which is an air inlet and the other end is an air outlet. The side wall of the duct is provided with an inclined groove one and a groove two. The inner wall of the duct is provided with a slot corresponding to the position of the groove one. A filter screen is detachably installed between the groove one and the slot. A basket with an open top is retractably provided in the groove two. The basket is filled with activated carbon material.

[0006] Preferably, a pair of limiting plates are fixedly provided between the inner top wall and the inner bottom wall of the air duct along the extension direction of the second groove, and the basket is slidably disposed between the two limiting plates.

[0007] Preferably, the basket is provided with a mounting plate one at one end of the outside of the air duct, and the filter is provided with a mounting plate two at one end of the outside of the air duct. The mounting plate one and the mounting plate two are respectively fixed to the outer wall of the pipe body by bolts, and both the mounting plate one and the mounting plate two are provided with handles.

[0008] Preferably, the top of the filter screen is inclined towards the air inlet, and the bottom wall of the air duct is provided with a dust discharge port between the bottom of the filter screen and the air inlet, and the dust discharge port is provided with an openable and closable sealing cover.

[0009] Preferably, the inner wall of the air duct is further provided with a guide plate in front of the filter screen. The guide plate is inclined towards the filter screen and its top has an arc-shaped arched structure. The inclined guide plate provided in front of the filter screen has an arc-shaped arched structure at its top.

[0010] Preferably, flanges are fixedly connected to both ends of the air duct.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. By setting up a detachable filter screen and a pull-out activated carbon basket, the filtration unit and adsorption unit are completely independent and modular. Maintenance personnel can replace or clean the filter screen and replace the activated carbon material separately and quickly from the outside without disassembling the air duct. This greatly simplifies the maintenance process, improves efficiency, and reduces long-term operation and maintenance costs.

[0013] 2. The filter screen is designed to be tilted towards the air inlet, and combined with the dust exhaust port at the bottom, larger particulate pollutants intercepted by the filter screen can slide down to the vicinity of the dust exhaust port under the action of gravity, making it easy to clean. This effectively reduces the accumulation of dust on the filter screen surface, thereby reducing wind resistance and the risk of secondary pollution caused by microbial growth.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] like Figure 1-4 As shown, this utility model proposes an air duct with air purification function, including an air duct 1. Both ends of the air duct 1 are fixedly connected to flanges 16. One end of the air duct 1 is an air inlet 2, and the other end is an air outlet 3. The side wall of the air duct 1 is provided with an inclined groove 1 4 and a groove 2 5. The inner wall of the air duct 1 is provided with a slot 6 corresponding to the position of the groove 1 4. A filter screen 7 is detachably installed between the groove 1 4 and the slot 6. A basket 8 with an open top is detachably installed in the groove 2 5. The basket 8 is filled with activated carbon material. By setting the detachable filter screen 7 and the detachable activated carbon basket 8, the filter screen 7 can be replaced or cleaned separately and quickly from the outside. The filter screen 7 is designed to be inclined towards the air inlet 2, and combined with the dust discharge port 13 set at the bottom, the larger particulate pollutants intercepted by the filter screen 7 can slide down to the vicinity of the dust discharge port 13 under the action of gravity, which is convenient for centralized cleaning.

[0022] like Figure 2 As shown, a pair of limiting plates 9 are fixedly provided between the inner top wall and the inner bottom wall of the air duct 1 along the extension direction of the groove 2 5, and the basket 8 is slidably disposed between the two limiting plates 9.

[0023] like Figure 4 As shown, the basket 8 is provided with a mounting plate 10 at one end outside the air duct 1, and the filter screen 7 is provided with a mounting plate 11 at one end outside the air duct 1. The mounting plate 10 and the mounting plate 11 are respectively fixed to the outer wall of the pipe body by bolts, and both the mounting plate 10 and the mounting plate 11 are provided with handles 12.

[0024] like Figure 1 As shown, the top of the filter screen 7 is inclined towards the air inlet 2, and the bottom wall of the air duct 1 is provided with a dust discharge port 13 between the bottom of the filter screen 7 and the air inlet 2. The dust discharge port 13 is provided with an openable and closable sealing cover 14.

[0025] like Figure 2As shown, the inner wall of the air duct 1 is also provided with a guide plate 15 in front of the filter screen 7. The guide plate 15 is inclined towards the filter screen 7 and its top has an arc-shaped arched structure. The inclined guide plate 15 in front of the filter screen 7 has an arc-shaped arched structure at its top. The guide plate 15 can guide the incoming airflow upward, so that the airflow enters from above the filter screen 7. Since the airflow mainly acts on the upper part of the filter screen, the intercepted dust will slide down the inclined surface under the action of gravity after losing the airflow adsorption force, and finally accumulate near the dust discharge port 13 at the bottom of the air duct 1 for easy collection.

[0026] In practical use, air enters the duct 1 through the air inlet 2 and is first guided by the guide plate 15, so that the airflow enters from above the filter screen 7. After being intercepted by the filter screen 7, particulate pollutants in the air are filtered out. Some dust slides down the inclined filter screen surface under the action of gravity to the vicinity of the dust outlet 13 at the bottom of the duct 1. Then, the air that has been preliminarily filtered passes through the basket 8 filled with activated carbon. The gaseous pollutants, odors and other substances in the basket are adsorbed by the activated carbon. Finally, the clean air is sent out from the air outlet 3.

[0027] Loosen the bolts on mounting plate 11, and hold handle 12 to pull the entire filter screen 7 out of the air duct 1 for cleaning or replacement. After completion, reinsert and tighten it.

[0028] Loosen the bolts on the mounting plate 10, hold the handle 12 on it to pull the entire basket 8 out of the air duct 1, pour out the old activated carbon, replace it with new activated carbon material, and then push the basket 8 back into the air duct 1 and tighten it.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
