Description

Technical Field

[0001] This application relates to the field of air filtration technology, and in particular to a fresh air system. Background Technology

[0002] With the booming development of the new energy industry, a large number of dehumidifiers and combined air conditioners are used in various production workshops to ensure the production environment of battery cells. This is because outdoor fresh air can be processed into clean air with temperature and humidity that meet the process requirements of different stages of battery cell production after passing through the filters, surface coolers, heaters, rotors and other components in the dehumidifier or combined air conditioner, thereby ensuring the quality of battery cells and improving the performance and safety reliability of batteries.

[0003] Improving the quality of fresh air is particularly crucial and important. Traditional fresh air ducts connect directly from the outside to the equipment inlet, but they are now gradually being replaced by fresh air sandwich walls, where outdoor fresh air flows through the sandwich walls and then to the equipment inlet. However, outdoor fresh air carries impurities or particles during its flow, which not only affects the air quality in the production line but may also affect the quality of the battery cells.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0035] This application provides a fresh air system, including a fresh air wall, an air handling unit, a fresh air duct 2, and a fresh air pretreatment device 1.

[0036] A fresh air wall is a building structure that combines fresh air supply with a wall structure. By setting up an air supply structure or equipment in the wall, the fresh air wall delivers outdoor air into the room. Its main function is to achieve indoor and outdoor air exchange and optimize air quality.

[0037] Air handling equipment can be dehumidifiers, combined air conditioners, and other devices used to process air. Air handling equipment can process air into clean air with the required temperature and humidity to meet the needs of production, work, or life.

[0038] Fresh air duct 2 is connected to the fresh air wall and the air handling unit respectively. Outdoor fresh air can flow to the air handling unit through fresh air duct 2 after entering the fresh air wall.

[0039] like Figure 4 As shown, the fresh air pretreatment device 1 is installed in the fresh air duct 2. The fresh air pretreatment device 1 is used to filter the fresh air flowing from the fresh air wall to the air handling equipment.

[0040] By installing a fresh air pretreatment device 1 on the fresh air duct 2, the outdoor fresh air can be pre-filtered, improving the cleanliness of the fresh air and making the fresh air entering the air handling equipment cleaner, thus reducing the workload and usage cost of the primary filter in the air handling equipment.

[0041] The beneficial effects of the technical solution provided in this application embodiment include at least the following: by setting up a fresh air pretreatment device 1 and placing the fresh air pretreatment device 1 in the fresh air duct 2, the fresh air pretreatment device 1 can be used to perform preliminary filtration of the fresh air flowing from the fresh air wall to the air handling equipment, blocking impurities or particles carried in the fresh air, which is conducive to improving the quality of fresh air, preventing dust or particulate matter from entering the production equipment, and improving the cleanliness of the working environment.

[0042] In a further embodiment, the fresh air pretreatment device 1 includes an outer frame 11 and a filter layer 12, the filter layer 12 being fixed within the space enclosed by the outer frame 11.

[0043] like Figure 2 or Figure 3 As shown, the outer frame 11 is ring-shaped, and the filter layer 12 covers the space enclosed inside the outer frame 11.

[0044] For example, the filter layer 12 can be a filter material such as cloth, activated carbon, glass fiber, or filter paper, which can provide sufficient air intake while adsorbing dust and other particles.

[0045] Optionally, the shape of the outer frame 11 is the same as the cross-sectional shape of the fresh air duct 2. For example, when the cross-sectional shape of the fresh air duct 2 is rectangular, such as... Figure 2 or Figure 3 As shown, the outer frame 11 is also rectangular. This design facilitates the positioning and installation of the fresh air pretreatment device 1.

[0046] It is understandable that the cross-section of the fresh air duct 2 is the cross-section obtained by cutting along a direction perpendicular to the extension direction of the fresh air duct 2.

[0047] In one specific embodiment, the filter layer 12 is a non-woven fabric layer.

[0048] Optionally, the filter layer 12 can be a needle-punched nonwoven fabric layer, a spunlace nonwoven fabric layer, a meltblown nonwoven fabric layer, a spunbond nonwoven fabric layer, etc.

[0049] By setting the filter layer 12 to be a non-woven fabric layer, it not only has good air permeability and large dust holding capacity, but also has the advantages of being economical and durable, which helps to reduce the operating cost of the fresh air system.

[0050] In one embodiment, the fresh air pretreatment device 1 further includes a support net 13, which is disposed within the space enclosed by the outer frame 11. The support net 13 is grid-shaped and located on one side of the filter layer 12.

[0051] like Figure 2 As shown, the support net 13 includes crisscrossing horizontal and vertical ribs, which extend within the space enclosed by the outer frame 11, making the support net 13 appear as a grid or mesh.

[0052] By setting up the support net 13, while ensuring sufficient ventilation, it can also support the filter layer 12, preventing the filter layer 12 from being deformed or damaged under the impact of fresh air, which is conducive to improving the durability and reliability of the fresh air pretreatment device 1.

[0053] Furthermore, the filter layer 12 is located on the side of the support net 13 near the fresh air duct 2.

[0054] This arrangement positions the filter layer 12 upstream of the support net 13 in the air intake direction, allowing the support net 13 to support the filter layer 12 from the back, thus ensuring that the filter layer 12 will not be deformed or damaged by the impact of fresh air.

[0055] In one embodiment, there are multiple filter layers 12, which are stacked together.

[0056] For example, multiple filter layers 12 are stacked along the extension direction of the fresh air duct 2.

[0057] The multiple filter layers 12 can be of the same type or different; the multiple filter layers 12 can be set on the same side of the support net 13 or distributed on both sides of the support net 13.

[0058] By setting multiple filter layers 12, the filtration effect of the fresh air pretreatment device 1 on fresh air is improved, which can adsorb more particles and improve the cleanliness of fresh air.

[0059] In one embodiment, the fresh air pretreatment device 1 further includes a fixing device 14 for fixing the filter layer 12 to the outer frame 11.

[0060] Optionally, the fixing device 14 is a strap. When the filter layer 12 is a non-woven fabric layer, the fixing device 14 can wrap around the outer frame 11 to bind the filter layer 12 and prevent the filter layer 12 from detaching from the outer frame 11.

[0061] Optionally, the fixing device 14 is a clamp, a clip, or other snap-fit ​​element, and there are multiple fixing devices 14, such as... Figure 3 As shown, multiple fixing devices 14 are spaced apart to clamp the filter layer 12 onto the outer frame 11.

[0062] By setting the fixing device 14, the connection strength and stability between the filter layer 12 and the outer frame 11 are improved, preventing the filter layer 12 from detaching from the outer frame 11.

[0063] In one embodiment, the fresh air pretreatment device 1 is detachably installed in the fresh air duct 2.

[0064] For example, such as Figure 4 As shown, the fresh air pretreatment device 1 is installed in the fresh air duct 2 by threaded fasteners 3, which are screws, bolts or studs.

[0065] By setting the fresh air pretreatment device 1 to be detachably connected to the fresh air duct 2, it is convenient to disassemble and install the fresh air pretreatment device 1 and replace the filter layer 12, which helps to improve the maintenance efficiency of the fresh air pretreatment device 1.

[0066] In one embodiment, the fresh air duct 2 is provided with a guide rail device 21, which is used to cooperate with the fresh air pretreatment device 1 and to limit the movement path of the fresh air pretreatment device 1.

[0067] like Figure 4 As shown, the guide rail device 21 is located at the bottom of the fresh air duct 2, and the fresh air pretreatment device 1 can be installed along the guide rail device 21 to a preset position in the fresh air duct 2.

[0068] By setting the guide rail device 21, stable support and guidance can be provided for the fresh air pretreatment device 1, guiding the fresh air pretreatment device 1 to move along a predetermined trajectory, thereby improving the assembly and disassembly efficiency of the fresh air pretreatment device 1.

[0069] In one embodiment, the fresh air system further includes a drive device, which is connected to the fresh air pretreatment device 1 for driving the fresh air pretreatment device 1 to move.

[0070] Optionally, the driving device is a power device such as a cylinder, motor, or electric push rod, which can automatically drive the fresh air pretreatment device 1 to move, so as to facilitate the installation of the fresh air pretreatment device 1 or to separate the fresh air pretreatment device 1 from the fresh air duct 2.

[0071] Optionally, the drive device is a manual transmission mechanism, such as a hand-cranked fixed pulley lifting bracket. The steel wire rope is rotated by manually cranking the handle, which in turn drives the fresh air pretreatment device 1 to rise and fall, so that the fresh air pretreatment device 1 is disconnected from the fresh air duct 2, so that the fresh air pretreatment device 1 can be cleaned or replaced.

[0072] For example, such as Figure 1 As shown, the fresh air pretreatment device 1 also includes a handle 15, which is located on the top of the outer frame 11 for easy handling by the operator.

[0073] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
