[0048] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application, and the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those skilled in the art without creative work on the basis of the embodiments of the present application shall belong to the protection scope of the present application.

[0049] For the convenience of description, the coordinate system is defined as Figure 1 As shown, the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.

[0050] Embodiment 1

[0051] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, an electrostatic adsorption dust removal device for green construction includes a main housing 1, and a purified air duct is provided in the main housing 1 and runs through the main housing 1 in the front-to-back direction. As a specific implementation, the main housing 1 described in this embodiment includes a top plate, a bottom plate, a left side plate and a right side plate, and the top plate, the left side plate, the bottom plate and the right side plate are sequentially connected end to end to form a cylindrical structure with a front and rear opening and a square cross-section, and the internal space of the cylindrical structure is the purified air duct.

[0052] The purified air duct is provided with a grille unit 2 and a dust collecting unit 3 from front to back, the grille unit 2 is connected to the negative pole of a DC power supply (not shown in the figure), and the dust collecting unit 3 is connected to the positive pole of the DC power supply.

[0053] The main housing 1 is provided with an air induction unit 4 at the rear side of the dust collecting unit 3. The air induction unit 4 includes an air induction pipe 41 connected to the purified air duct and a fan 42 for blowing air into the air induction pipe 41. Under the guidance of the air induction pipe 41, the air flow can move to the side facing away from the dust removal unit after entering the purified air duct, that is, to the side of the air outlet at the rear side.

[0054] like Figure 3 As shown, by supplying air into the purified air duct through the induced draft unit 4, negative pressure can be formed in the purified air duct, thereby driving smoke and dust to enter the device from the air inlet on the front side of the purified air duct. At this time, since the negative pole of the DC power supply is connected to the grille unit 2, and the positive pole of the DC power supply is connected to the dust collection unit 3, a corona zone will be formed between the grille unit 2 and the dust collection unit 3. The air in the corona zone is ionized, generating a large number of negative ions and positive ions, and the positive ions move toward the grid to be neutralized. After entering the purified air duct, the smoke and dust will combine with the negative ions, and move toward the dust collection unit 3 driven by the negative ions, thereby being adsorbed on the dust collection unit 3.

[0055] like Figure 7 and Fig.13 As shown, the grille unit 2 includes a plurality of grille columns 211 arranged in parallel, and the plurality of grille columns 211 are arranged in a line along one direction (according to Figure 1 The coordinate system shown in the figure, several of the grille columns 211 are arranged in a straight line in the horizontal direction). The upper end of the grille column 211 is fixedly provided with a first connecting clamp plate 212 by welding, and the first connecting clamp plates 212 of several of the grille columns 211 are connected to the first terminal block 22 in a detachable manner. The dust suction unit 3 includes a connecting column 31 extending in the horizontal direction, and a plurality of dust suction springs 321 are evenly distributed in the axial direction on the connecting column 31. A second terminal block 312 is fixedly provided on the connecting column 31 in a detachable manner. The negative pole of the DC power supply is connected to the first terminal block 22 through a first wire, and the positive pole of the DC power supply is connected to the second terminal block 312 through a second wire.

[0056] As a specific implementation method, Figure 8 , Fig.10 and Fig.11 As shown, the first connecting clamp plate 212 in this embodiment includes a first web 2121, and the grid column 211 is fixedly connected to the bottom surface of the first web 2121 by welding. Figure 1 The first wing plates 2122 extending upward perpendicularly to the first web 2121 are respectively provided at both ends of the first connection plate 2121. The first web 2121 and the first wing plates 2122 together form a plug-in slot with an opening facing upward. The lower end of the first connection plate 22 is inserted into the plug-in slot, and a first tightening screw 23 for tightening the first connection plate 22 is provided on one of the first wing plates 2122. Under the tightening action of the first tightening screw 23, the first connection plate 22 is pressed against the other first wing plate 2122, thereby achieving reliable contact between the first connection plate 22 and the first connecting clamp 212, thereby ensuring smooth conduction and avoiding heating problems caused by poor local contact or virtual connection.

[0057] As a specific implementation method, Fig.15 and Fig.18 As shown, the dust suction spring 321 described in this embodiment is connected to the connecting column 31 through a second connecting clamp plate 322. The second connecting clamp plate 322 includes a second web 3221, and the dust suction spring 321 is fixedly connected to the bottom surface of the second web 3221 by welding. The second web 3221 is provided with second wing plates 3222 extending upward perpendicularly to the second web 3221 on the front and rear sides of the connecting column 31. A connecting shaft 323 is passed through the connecting column 31, and the two ends of the connecting shaft 323 are respectively connected to the two second wing plates 3222 of the second connecting clamp plate 322. Exemplarily, the second connecting clamp plate 322 is connected to the connecting column 31 through a bolt assembly.

[0058] As a specific implementation method, Fig.15 and Fig.19 As shown, the connecting column 31 described in this embodiment is provided with a plug-in hole which radially penetrates the connecting column 31, the second wiring board 312 is inserted into the plug-in hole, and the connecting column 31 is provided with a second tightening screw 313 for tightening the second wiring board 312.

[0059] Furthermore, a limiting plate 3121 is provided on the second wiring board 312 at one side of the connecting column 31. The limiting plate 3121 can prevent the second wiring board 312 from loosening and slipping off the connecting column 31 during operation. Exemplarily, the limiting plate 3121 is an arc-shaped structure coaxially arranged with the connecting column 31, and the inner diameter of the limiting plate 3121 is equal to the diameter of the connecting column 31.

[0060] Furthermore, if Figure 6 and Figure 7 As shown, the grille unit 2 further includes a mounting box 24 in a conical cylindrical structure, and the mounting box 24 is fixedly connected to the main housing 1 in a detachable manner. The large end opening of the mounting box 24 faces the front side (i.e., the air inlet side), and the small end opening of the mounting box 24 faces the rear side (i.e., the air outlet side). The grille column 211 is arranged at the small end opening of the mounting box 24.

[0061] As a specific implementation, the installation box 24 described in this embodiment is formed by four side panels connected end to end in sequence, and the four side panels together form a four-sided pyramid structure. The installation box 24 includes a first installation portion 241, a conical portion 242, and a second installation portion 243 from front to back. The four sides of the first installation portion 241 are respectively parallel to the four sides of the main shell 1, and the first installation portion 241 is fixedly connected to the main shell 1 by screws. A plurality of installation holes that penetrate the second installation portion 243 in the vertical direction are evenly distributed along the horizontal direction on the second installation portion 243. The number of the installation holes is the same as the number of the grille columns 211, and the positions correspond one to one. The grille columns 211 are inserted into the corresponding installation holes from top to bottom, and the first connecting clamp plate 212 is located at the upper end of the grille columns 211.

[0062] By providing the installation box 24, on the one hand, the overall installation and disassembly of the grille unit 2 can be realized to facilitate future maintenance work; on the other hand, by providing the installation box 24 with a quadrangular pyramid structure and making its large end opening face the air inlet side, the air intake can be strengthened, making it easier for smoke and dust to enter the purified air duct.

[0063] Furthermore, if Fig. 9 , Fig.10 and Fig.11 As shown, the installation box 24 is made of metal material, and a first insulating sleeve 25 is provided between the upper side panel of the second installation portion 243 and the grille column 211, and between the lower side panel of the second installation portion 243 and the grille column 211. The first insulating sleeve 25 can block the conductivity between the grille column 211 and the installation box 24, thereby preventing the installation box 24 from being charged.

When the locking plate 252 is tightened, the side panel of the second mounting portion 243 is clamped between the first end plate 2512 and the locking plate 252. The first end plate 2512 and the first sleeve 2511 are an integrated structure and are made of insulating material. The locking plate 252 is made of insulating material.

[0065] Furthermore, if Fig.12 and Fig.13As shown, the connecting column 31 is slidably connected to the main housing 1 through a sliding assembly, and the connecting column 31 can slide up and down relative to the main housing 1. A rotating shaft 33 arranged parallel to the connecting column 31 is rotatably provided on the main housing 1, and the rotating shaft 33 can rotate around its own axis under the drive of the driving component. A cam 332 mechanism is provided between the rotating shaft 33 and the connecting column 31, and an elastic member is provided between the connecting column 31 and the main housing 1. When the rotating shaft 33 rotates around its own axis under the drive of the driving component, the connecting column 31 can reciprocate up and down relative to the main housing 1 under the joint action of the cam 332 mechanism and the elastic member, so as to shake off the dust adsorbed on the dust collecting spring 321.

[0066] As a specific implementation, the two ends of the connecting column 31 in this embodiment are respectively fixed with a connecting seat 351 in a detachable manner. The connecting seat 351 is respectively provided with guide columns 352 extending upward on both sides of the connecting column 31, and the upper ends of the guide columns 352 extend through the top plate of the main housing 1 to the outside of the main housing 1, and the top plate of the main housing 1 is provided with a guide slide 353 that matches the guide columns 352. The rotating shaft 33 is located between the connecting column 31 and the top plate of the main housing 1, and the two ends of the rotating shaft 33 are rotatably connected to the top plate through bearing assemblies 331. The cam 332 mechanism includes cams 332 respectively provided at the two ends of the rotating shaft 33, and the elastic member is used to prevent the connecting column 31 from moving downward. When the cam 332 is in the pushing stage, the cam 332 can push the connecting column 31 to move downward, and the elastic member is compressed. When the cam 332 is in the returning stage, the connecting column 31 can move upward under the elastic action of the elastic member, thereby being close to the cam 332.

[0067] As a specific implementation method, Fig.16 As shown, in this embodiment, the top end of the guide column 352 is provided with a baffle 3521, and the elastic member is a return spring 36 sleeved on the guide column 352, the upper end of the return spring 36 abuts against the baffle 3521, and the lower end of the return spring 36 abuts against the main housing 1 or the guide slide 353.

The transmission mechanism includes a driving bevel gear 342 arranged on the power output shaft of the driving motor 341 and a driven bevel gear 343 arranged on the rotating shaft 33. The driving bevel gear 342 and the driven bevel gear 343 are meshed with each other to transmit the power of the driving motor 341 to the rotating shaft 33, thereby driving the rotating shaft 33 to rotate.

[0072] Furthermore, the driving motor 341 is a servo motor, and during dust removal, the vibration frequency of the connecting column 31 moving up and down can be adjusted by controlling the rotation speed of the driving motor 341 to make it close to the natural frequency of the dust collecting spring 321, so as to achieve a resonance effect. In this way, the dust collecting spring 321 can be shaken violently, thereby shaking off the dust on the dust collecting spring 321.
