Description

Technical Field

[0001] This application relates to the field of static electricity elimination technology, and in particular to a static electricity elimination and purification device. Background Technology

[0002] Static electricity (STO) has always been a significant concern in industrial production and daily life. STO is extremely common, with contact and separation generating the most frequent form of static electricity. The presence of STO can have numerous adverse effects, especially in certain environments where it poses significant safety hazards, such as potentially igniting flammable gases. In cleanrooms and other environments with extremely high environmental requirements, companies often need to invest substantial financial and material resources to maintain a clean environment. Furthermore, STO poses a potential threat to production processes and product quality; therefore, addressing STO is crucial for ensuring production safety and product quality. In addition, with industrial development, the requirements for clean and static-free environments such as workshops are becoming increasingly stringent, and the development of related technologies plays a positive role in improving production efficiency and product quality.

[0003] Currently, to solve static electricity problems, factories often use FFUs (Fan Filter Units) and static eliminators to maintain a dust-free and static-free environment in the workshop. Static eliminators can eliminate static electricity within their coverage area, but they can only protect products from static electricity and cannot protect the environment. Common static electricity removal methods also include static grounding, humidification, adding antistatic additives, and static neutralizers. Static grounding connects objects to the earth, allowing static electricity to be conducted to the ground through a grounding wire; humidification increases ambient humidity, causing a conductive film to form on the surface of objects, thereby reducing static electricity generation; adding antistatic additives involves adding substances that reduce surface resistance to materials, reducing the accumulation of static electricity; static neutralizers, also known as static eliminators, use electricity and ions to complete the static electricity removal process.

[0004] However, these existing technologies have significant drawbacks. Static grounding is not suitable for gases, as gases are mostly poor conductors of electricity. Humidification and the addition of antistatic additives are limited by gas composition and application scenarios, significantly restricting their applicability. While static neutralizers can eliminate static electricity, commonly used matching gas circulation equipment such as motors and impellers are too heavy and bulky, limiting their installation environment. Furthermore, many manufacturers now use substandard static eliminators to save costs, which can produce reverse charging effects, affecting the equilibrium values ​​of the target object. In addition, static eliminators can only eliminate static electricity within their coverage area, not outside of it, and the discharge needle support rod is placed at the edge of the equipment, making it prone to discharge with surrounding metal materials.

It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0026] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0027] The technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of the present invention without creative effort are also within the protection scope of the present invention.

[0028] See Figure 1 , Figure 2 and Figure 3 The present application discloses an antistatic purification device, which includes a main housing 10, an airflow circulation assembly 20, a lower cover plate 30, and an ion generation assembly 40.

[0029] The main housing 10 serves as the basic framework of the entire device, providing space for the installation and support of other components. The airflow circulation assembly 20 is fixedly installed inside the main housing 10, drawing in outside air and filtering it. The lower cover 30 is connected to the main housing 10 via a hinge 12, accommodating and abutting the filter element 23 within the airflow circulation assembly 20. The central area of ​​the lower cover 30 is the air outlet area 31 corresponding to the filter element 23 (see [reference]). Figure 4 This ensures that purified air flows out from this area. The ion generating component 40 is installed on the main housing 10 and the lower cover 30, generating ions and releasing them into the air outlet area 31 to achieve static electricity removal. Thus, through the cooperation of the various components, the equipment can simultaneously achieve air purification and static electricity removal, and the good synergy of the components improves the overall performance of the equipment.

[0030] Specifically, an air inlet 11 is provided on the end face of the main housing 10, serving as a channel for outside air to enter the main housing 10. The main housing 10 can be made of metal, such as stainless steel or aluminum alloy, which has good strength and durability, or it can be made of high-strength plastic to reduce the weight of the equipment. The shape of the air inlet 11 can be circular, square, etc., and the specific shape can be determined according to actual design requirements.

[0031] See Figure 2 and Figure 3 The airflow circulation assembly 20 includes a support member 21, an external rotor fan 22, and a filter element 23. The support member 21 is fixedly installed inside the main housing 10, serving to support and fix other components. The support member 21 can be a metal bracket, such as an iron or aluminum bracket, or a plastic bracket, possessing a certain strength and stability.

[0032] The external rotor fan 22 is located inside the main housing 10 and is mounted on the support 21 relative to the air inlet 11. The external rotor fan 22 can generate strong suction, drawing outside air into the main housing 10 from the air inlet 11. In this embodiment, the external rotor fan 22 can be a DC brushless external rotor fan 22, which has advantages such as high efficiency, energy saving, and low noise. Of course, other types can also be selected according to actual needs.

[0033] The filter element 23 is located at the end of the support member 21 away from the external rotor fan 22, and is used to filter dust, particulate matter, and other impurities in the air. The filter element 23 can be a filter screen, such as a HEPA filter, which can effectively filter fine particulate matter; or it can be an activated carbon filter, which can adsorb odors and harmful gases. The filter element 23 is housed and supported by the lower cover plate 30, and is detachable for easy replacement and maintenance.

[0034] Further, see Figure 2 and Figure 3 To facilitate the smoother entry of outside air into the external rotor fan 22, the airflow circulation assembly 20 also includes an air guide 24. The air guide 24 is located inside the main housing 10, with one end facing the air inlet 11 and fixed inside the main housing 10, and the other end facing the external rotor fan 22. The structural shape of the air guide 24 is as follows... Figure 3As shown, the air intake path of the airflow circulation component 20 has been optimized, allowing air to enter the external rotor fan 22 more efficiently and improving the overall performance of the equipment.

[0035] Here, the airflow circulation assembly 20 works as follows: After the external rotor fan 22 starts, it generates suction, drawing outside air from the air inlet 11 into the main housing 10 through the air guide 24. When the air passes through the filter 23, dust, particulate matter, and other impurities are filtered out, and the purified air continues to flow. The cooperation of the air guide 24, the external rotor fan 22, and the filter 23 achieves the functions of air introduction and filtration, ensuring that the air entering the main housing 10 is clean.

[0036] See Figure 2 As shown in Figure 4, the lower cover plate 30 is located on the end face of the main housing 10 away from the air inlet 11. It is connected to the main housing 10 via the hinge 12. The lower cover plate 30 is used to accommodate and abut against the filter element 23 through the frame to ensure the stable installation of the filter element 23.

[0037] The lower cover 30 is connected to one end of the main housing 10, and the other end is designed to be openable and closable for easy replacement of the filter element 23. The hinge 12 is a heavy-duty metal hinge, or a hinge with a buffer function, to ensure smooth opening and closing of the lower cover 30. In addition, the middle area of ​​the lower cover 30 is the air outlet area 31, from which purified air flows out.

[0038] See Figure 3 and Figure 5 The ion generating assembly 40 includes an ion generating element 41, a high-voltage control element 42, and a discharge needle 43. The ion generating element 41 is disposed on the inner frame of the main housing 10, with two elements located at the two ends of the support member 21. The ion generating element 41 ionizes molecules in the air into equal amounts of positive and negative ions through high-voltage discharge. The ion generating element 41 can be an ion generator chip or other types of ion generating devices.

[0039] The high-voltage control component 42 is mounted on the support component 21 and electrically connected to the ion generator 41. It is used to control the operating voltage and current of the ion generator 41. The high-voltage control component 42 can be a high-voltage power supply module, capable of providing a stable high-voltage output. It is worth mentioning that in practical applications, an insulating adhesive (epoxy adhesive) is coated on the high-voltage control component 42 to form an isolation layer, separating the high-voltage control component 42 from other metal components and avoiding electrostatic ion interference.

[0040] See also Figure 4 The discharge needle 43 is located on the edge of the end face of the lower cover plate 30 away from the main housing 10, and the discharge needle 43 is L-shaped (e.g., Figure 2As shown in the diagram, the discharge end of the discharge needle 43 extends to the air outlet area 31. The L-shaped design of the discharge needle 43 allows ions to diffuse better into the air outlet area 31, improving the static electricity removal effect.

[0041] The working principle of the ion generating component 40 is as follows: the high-voltage control component 42 provides a high-voltage power supply to the ion generating component 41. The ion generating component 41 ionizes molecules in the air into equal amounts of positive and negative ions through high-voltage discharge, forming an ion cloud. These ions are released into the air outlet area 31 through the discharge needle 43, neutralizing the static electricity in the air and thus achieving the function of static removal. The coordinated work of the ion generating component 41, the high-voltage control component 42, and the discharge needle 43 ensures that ions are evenly distributed in the air outlet area 31, improving the static removal effect and resulting in better static dissipation time and voltage balancing.

[0042] Further, see Figure 1 and Figure 2 In addition to the electrostatic purification equipment, the control and monitoring component 50 is also included. The control and monitoring component 50 is located on one side of the main housing 10 and includes a display component 51, a centralized control component 52 and a differential pressure switch 53.

[0043] The display panel of display component 51 is exposed outside the main housing 10, allowing users to easily view the equipment's operating status and related parameters. (See also...) Figure 3 The display component 51 may be a liquid crystal display screen, and may include a display panel, a light shield, and a display panel, etc., which are not limited here.

[0044] The centralized control unit 52 and the differential pressure switch 53 are located inside the main housing 10. The centralized control unit 52 is electrically connected to the display unit 51, the differential pressure switch 53, the high-voltage control unit 42 and the discharge needle 43. This allows for centralized control and management of the various components of the equipment. Users can set the operating mode, wind speed and other parameters of the equipment through the display unit 51.

[0045] The differential pressure switch 53 is used to monitor the pressure difference on both sides of the filter element 23. When the pressure difference reaches a certain value, it indicates that the filter element 23 needs to be replaced. At this time, the differential pressure switch 53 will transmit the signal to the central control unit 52, and the central control unit 52 will remind the user to replace the filter element 23 through the display unit 51.

[0046] Further, see Figure 2 To prevent external debris from entering the air inlet 11 and protect the internal components of the equipment, the electrostatic purification equipment also includes an air inlet hood 25, which is located on the outside of the main housing 10. This hood covers the air inlet 11 to perform preliminary filtration and rectification of the incoming air, helping to improve the air intake quality and purification effect of the equipment. The shape of the air inlet hood 25 can be determined according to actual design requirements, such as round or square.

[0047] Further, see Figure 1 and Figure 3 One end of the lower cover plate 30 is movably connected to the main body 10 via a hinge 12. The other end of the lower cover plate 30 is provided with a fastening element 32, and the corresponding main body 10 is provided with a clip 13. The main body 10 is fastened to the lower cover plate 30 by the clip 13 and the fastening element 32.

[0048] The fastener 32 and the clip 13 are compatible stainless steel quick-release clips 13. This fastening method makes it easier to open and close the lower cover 30, while also ensuring a tight connection between the lower cover 30 and the main body 10. In addition, an embedded handle 14 is provided on the outer side of the main body 10 away from the hinge 12, that is, near the clip 13, to facilitate the user to open the main body 10 and the lower cover 30, or to move equipment.

[0049] Further, see Figure 1 Multiple movable handles 15 are also provided at the end of the main body 10 away from the lower cover plate 30, which can further facilitate the movement of the equipment.

[0050] See also 4. A side-mounted column 16 is also provided on the side of the main housing 10. The side-mounted column 16 can be laid down after the equipment is laid down, for example when the discharge needle 43 is installed, to provide support.

[0051] Thus, the fasteners 32, clips 13, and recessed handles 14 facilitate the opening, closing, and fixing of the lower cover 30, making it easy to replace and maintain the filter element 23. The movable handle 15 improves the portability of the equipment, making it convenient for users to move and relocate the equipment. The side-mounted column 16 enhances the support of the main housing 10.

[0052] In summary, the static electricity removal and purification equipment disclosed in this application involves an external rotor fan 22 of the airflow circulation assembly 20 drawing air in from the air inlet 11 via the air guide 24, filtering it through the filter 23, and then discharging it from the air outlet area 31 of the lower cover 30. Simultaneously, the ion generating assembly 40 generates ions. The two work together to effectively remove static electricity and purify the air. The lower cover 30 is connected to the main housing 10 via the hinge 12 and fixed by the fastener 32 and the clip 13, facilitating the placement and contact of the filter 23, making it convenient for the replacement and maintenance of the filter device, and improving the equipment's efficiency and purification effect. The discharge needle 43 is L-shaped with its discharge end extending to the air outlet area 31, which enables more uniform ion distribution, improves the static electricity removal effect, and overcomes the problems of limited installation environment and easy discharge between the discharge needle 43 support rod and surrounding metal substances. The control and monitoring assembly 50 can centrally control and monitor the equipment's operation, facilitating timely detection and handling of problems.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
