[0002] Electrostatic precipitators are highly efficient dust removal devices that utilize an electrostatic field to ionize gas, thereby charging dust particles and attracting them to electrodes. These devices are widely used in industrial production and daily life for flue gas purification and dust collection, playing a vital role in improving environmental quality and protecting worker health. Electrostatic precipitators can be installed in various locations depending on usage requirements. The electronic return air vent type electrostatic precipitator is one such device; installed at the return air vent of an air conditioner, it combines electrostatic dust removal technology with the air conditioner return air vent structure, saving space and offering high purification efficiency.

[0003] Existing return air vent type electrostatic precipitators are usually installed in the duct of the air conditioning return air vent using screw fixing. With this installation method, the collected dust needs to be cleaned after the equipment has been running for a period of time. Since the screw fixing method is relatively cumbersome, disassembly and cleaning are inconvenient and require tools to complete. This not only increases the time cost of maintenance, but may also cause damage to the equipment or insecure installation due to improper operation. Therefore, an electrostatic precipitator that is easy to install and fix is ​​proposed. Utility Model Content

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-5 As shown, this utility model embodiment provides an electrostatic dust removal device that is easy to install and fix, including a housing 16, and an installation component 101 is provided on the outside of the housing 16;

[0028] Mounting assembly 101 includes an outer mounting housing 11, a front mounting ring 17, a handle 21, and a limiting post 22;

[0029] The outer mounting shell 11 is fitted onto the outside of the housing 16, and the outer mounting shell 11 is fixed inside the air conditioner return air vent duct by screw installation.

[0030] A retaining ring 12 is fixedly connected to the rear part of the inner wall of the outer mounting shell 11. Insert pins 13 are symmetrically fixedly connected to the front surface of the retaining ring 12. A rear protruding ring 15 is fixedly connected to the rear part of the outer wall of the housing 16. Positioning holes 14 are symmetrically opened on the rear protruding ring 15. The rear protruding ring 15 fits against the front surface of the retaining ring 12. The insert pins 13 are inserted into the interior of the positioning holes 14. When installing the housing 16, the position of the housing 16 can be precisely defined by the cooperation of the insert pins 13 and the positioning holes 14.

[0031] A sealing ring (not shown in the figure) is provided between the contact surfaces of the rear convex ring 15 and the retaining ring 12 to ensure the airtightness of the connection of the housing 16;

[0032] When installing the housing 16, insert the end of the housing 16 with the rear protruding ring 15 into the outer mounting housing 11 so that the rear protruding ring 15 fits against the retaining ring 12. At the same time, the insert post 13 is inserted into the inside of the positioning hole 14. At this time, the rear of the housing 16 can be positioned.

[0033] The front mounting ring 17 is fixedly connected to the front part of the outer side wall of the housing 16. The outer wall of the front mounting ring 17 is attached to the inner side wall of the outer mounting shell 11. The front position of the housing 16 can be defined by the front mounting ring 17.

[0034] The front mounting ring 17 has symmetrical mounting grooves 18 on both sides. The mounting groove 18 is slidably connected to the inside of the mounting groove 19. The limiting post 22 is fixedly connected to the outer wall of the limiting post 19 at equal intervals. The limiting post 22 is sleeved with a spring 20. The handle 21 is installed on the front surface of the limiting post 19. The limiting post 19 can be moved into the mounting groove 18 by the handle 21.

[0035] The rear surface of the limiting plate 19 is a slope, and a corresponding slope is also provided at the position where the outer mounting shell 11 and the limiting plate 19 meet. Therefore, when the limiting plate 19 contacts the outer mounting shell 11, the limiting plate 19 can move into the interior of the mounting groove 18 under the drive of the slope.

[0036] One end of the spring 20 abuts against the limiting plate 19, and the other end of the spring 20 abuts against one side of the inner wall of the mounting groove 18. Two limiting slots 23 are symmetrically opened on the front part of the inner side wall of the outer mounting shell 11. The limiting plate 19 is inserted into the inside of the limiting slot 23. During the installation of the housing 16, when the outer wall of the front mounting ring 17 is in contact with the inner wall of the outer mounting shell 11 and the limiting plate 19 is aligned with the limiting slot 23, the limiting plate 19 will move outward and be inserted into the inside of the limiting slot 23 under the elastic force of the spring 20. The position of the housing 16 can be limited by the limiting plate 19, thereby completing the installation and fixation of the housing 16. The entire installation process does not require many tools and is simple and quick to operate.

[0037] In one embodiment, the handle 21 is located in front of the front mounting ring 17, and the front mounting ring 17 has a through groove to avoid the handle 21 so that the handle 21 can drive the limiting plate 19 to slide.

[0038] In one embodiment, an insulating mounting plate 31 is disposed inside the housing 16. Discharge electrodes 32 are equidistantly mounted on one side of the insulating mounting plate 31. An electrostatic metal tube 35 is mounted inside the housing 16 via a retainer. The retainer is secured to the outside of the electrostatic metal tube 35, with its end installed inside the housing 16. The electrostatic metal tube 35 is sleeved around the outside of the discharge electrodes 32 but does not contact them. The discharge electrodes 32 are connected to an external high-voltage power supply. This structural arrangement enables the electrostatic dust removal equipment to operate normally, using an electrostatic field to ionize the gas, causing dust particles to become charged and adsorbed onto the electrodes. Specifically:

[0039] When the equipment is running, the high-voltage power supply causes the discharge electrode 32 to generate corona discharge, which ionizes the surrounding gas and forms a large number of positive and negative ions. When the dust-laden gas passes by, the dust particles combine with the ions and become charged. Under the action of the electric field force, the charged dust particles move toward the electrostatic metal tube 35 and are deposited on its surface, thereby achieving air purification.

[0040] In one embodiment, a protective grille 34 is installed on the front of the inner sidewall of the housing 16. The protective grille 34 can play a protective role, preventing foreign objects from entering the housing 16 and damaging the equipment, and can also ensure the safety of operators to a certain extent.

[0041] When this utility model is in operation: the outer mounting shell 11 is fixedly installed in the duct of the air conditioner return air vent, and then the housing 16 is installed. The end of the housing 16 with the rear protruding ring 15 is inserted into the outer mounting shell 11, so that the rear protruding ring 15 fits against the retaining ring 12. The insert post 13 is inserted into the inside of the positioning hole 14. At this time, the rear of the housing 16 can be positioned. At the same time, the inclined surface of the limiting plate 19 contacts the outer mounting shell 11 and is pressed into the mounting groove 18. When the housing 16 is fully in place, under the elastic force of the spring 20, the limiting plate 19 is inserted into the inside of the limiting slot 23. Thus, the position of the housing 16 can be limited by the limiting plate 19.

[0042] During dust removal operations, the equipment is connected to the power supply. Since the equipment is installed in the duct of the air conditioner return air vent, air flows into the duct after passing through the casing 16. At this time, the discharge electrode 32 generates corona discharge, ionizing the surrounding gas and forming a large number of positive and negative ions. When the dust-laden gas passes by, the dust particles combine with the ions and become charged. Under the action of the electric field force, the charged dust particles move towards the electrostatic metal tube 35 and are deposited on its surface, thereby achieving air purification.

[0043] When disassembly and cleaning are required, first disconnect the power supply, then pull the two handles 21 closer together. The handles 21 drive the limiting plate 19, which slides in the mounting slot 18. When the limiting plate 19 is disengaged from the limiting slot 23, the limiting of the housing 16 is released, and the housing 16 can be removed to clean the dust collected inside.

[0044] Compared with the prior art, this utility model adopts a split structure, fixing the outer mounting shell 11 inside the air conditioner return air vent duct, while the housing 16 is fixed inside the outer mounting shell 11 by a snap-fit ​​method. This allows for quick disassembly and installation of the housing 16, replacing the traditional screw fixing method, which facilitates the disassembly and cleaning of the equipment, reduces maintenance time costs, and lowers the difficulty of operation.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
