Description

Technical Field

[0001] This invention relates to the field of cleaning and dust removal equipment, and more particularly to a dust removal system that integrates blowing and suction, and the dust removal method thereof. Background Technology

[0002] In industries such as precision machinery, electronic assembly, semiconductors, and packaging, the cleanliness requirements for the surfaces of parts, dust-collecting objects, or materials during the production process are extremely stringent. Even tiny dust particles, debris, and other contaminants can adversely affect the function of the dust-collecting objects.

[0003] Currently, common surface dust removal equipment mainly uses high-pressure fans or compressed air to generate airflow, which is blown onto the surface of the object to be dusted, blowing up the dust and debris attached to it. Then, the dust and debris are collected through an independent suction port near the blowing position. Through long-term practice, we have found that the blowing head and the suction port are spatially separated, and the airflow field of their coordinated action is difficult to optimize, which easily forms a turbulent airflow zone, causing some pollutants to escape. Summary of the Invention

[0004] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a dust removal system and method that integrates blowing and suction, which solves the technical problem that the blowing head and the suction port are spatially separated, making it difficult to optimize the airflow field of their synergistic effect, which easily forms a turbulent airflow zone and causes some pollutants to escape.

[0005] (II) Technical Solution On the one hand, the purpose of this invention is to provide a dust removal system that integrates blowing and suction, which includes a support mechanism; The blowing and suction integrated mechanism is disposed inside the support mechanism; An escape-proof dust collection mechanism is mounted on the support mechanism and located on both sides of the blowing and suction integrated mechanism along the conveying direction of the dust-collecting object; The blow-suction integrated mechanism includes: Mounting shaft; A first driving device is used to drive the mounting shaft to rotate; A rotary dust blowing assembly, located at one end of the mounting shaft, is used to blow air onto the surface of the object to be dusted; An air supply rotary joint, connected to the other end of the mounting shaft, is used to supply air to the rotary dust blowing assembly; A spiral dust collection assembly is mounted on the mounting shaft via a connecting bearing and is used to collect contaminants blown up by the rotary dust blowing assembly; The second driving device is used to drive the spiral dust collection assembly to rotate around the mounting shaft.

[0006] Preferably, the support mechanism includes a support rod, a drive roller, a conveyor belt, and an electrostatic bar. The drive roller is disposed at both ends of the support rod, the conveyor belt is wrapped around the drive roller to form a receiving space, and the electrostatic bar is disposed adjacent to the drive roller with its two ends respectively connected to the support rod.

[0007] Preferably, the anti-escape dust collection mechanism includes a limiting roller, a dust collection fan, and a support bracket. The number of dust collection fans is one or more and they are installed at the upper end of the support bracket. The limiting roller is disposed at the side end of the support bracket.

[0008] Preferably, the blowing and suction integrated mechanism further includes a frame and a transmission component, the first driving device and the second driving device are disposed on the frame, and the spiral dust suction assembly is connected to the second driving device through the transmission component.

[0009] Preferably, the mounting shaft forms a cavity inside, and the sidewall of the cavity has a plurality of through holes, through which the air supply rotary joint is connected to the rotary dust blowing assembly.

[0010] Preferably, the rotary dust blowing assembly includes a rotary auxiliary module, a straight connector, an air pipe, and an air nozzle. The straight connector is installed on the outer periphery of the rotary auxiliary module. One end of the air pipe is connected to the straight connector, and the other end of the air pipe is connected to the air nozzle.

[0011] Preferably, the rotating auxiliary module includes an air delivery adapter block, a rotating disk, a rotating support plate, and an air guide module. The rotating disk is disposed at the lower end of the air delivery adapter block. One end of the rotating support plate is connected to the rotating disk, and the other end is connected to the air nozzle. The air guide module is disposed at the end of the rotating support plate adjacent to the air nozzle.

[0012] Preferably, the air guide module includes an air guide horn tube and a mounting block. One end of the mounting block is fixed to the rotating support plate, and the air guide horn tube is mounted on the other end of the mounting block. The axis of the air guide horn tube is inclined relative to the horizontal plane, and the projection of the axis on the horizontal plane forms an angle with the direction of the rotation radius.

[0013] Preferably, the spiral vacuum assembly includes a spiral vacuum fan blade, a mounting base, and a driven gear. The spiral vacuum fan blade is disposed at one end of the mounting base, and the driven gear is disposed at the other end of the mounting base. The connecting bearing is internally connected to the mounting base.

[0014] On the other hand, the present invention also provides a dust removal method that integrates blowing and suction. First, the blowing and suction integrated mechanism set inside the support mechanism and the anti-escape suction mechanism set on both sides of the support mechanism form a dust removal area, and the dust removal object enters the dust removal area from the entrance of the dust removal area. Upon entering the dust removal zone, the coaxially arranged rotary dust blowing assembly and spiral dust suction assembly perform dust removal and dust suction respectively. The airflow output from the nozzle of the rotary dust blowing assembly forms a rotating output airflow field towards the dust removal object, blowing up the pollutants attached to the surface of the dust removal object. The pollutants blown up by the airflow are sucked up by the spiral dust suction assembly located at the center of the rotating output airflow field and transported to the external negative pressure dust collector for collection. Meanwhile, the air guide module located next to the air nozzle captures pollutants and directs them to the spiral dust collection assembly, while the escape prevention dust collection mechanism on both sides captures pollutants escaping towards the outlet and inlet on both sides of the dust collection area. After dust removal is completed, the dust-removed object is processed by the integrated blowing and suction mechanism before entering the next process from the outlet of the dust removal area.

[0015] (III) Beneficial Effects By coaxially arranging the rotary dust blowing component and the spiral dust suction component, and then independently cooperating with the first drive device and the second drive device respectively, a compact and efficient "blowing and suction integrated" structure is formed. When the rotary dust blowing component blows pollutants from the surface of the object to be dusted, the spiral dust suction component, which rotates coaxially with it, immediately generates a strong local negative pressure at the moment the dust floats up, directly sucking it in and collecting it. In addition, the anti-escape dust suction mechanism located on both sides of the blow-suction integrated mechanism can capture a small amount of drifting pollutants that may escape from the core working area. The blow-suction integrated mechanism and the anti-escape dust suction mechanism together constitute a multi-combination dust removal environment, which maximizes the prevention of pollutants from spreading to the outside of the equipment and protects the cleanliness of the overall production environment.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] The following is in conjunction with the appendix Figures 1 to 8 To further describe, the present invention discloses a dust removal system integrating blowing and suction, including a support mechanism 1, and several conveyor belts 2 wrapped around the transmission roller 11 of the support mechanism 1 by means of sleeve. The support mechanism 1 is provided with a blowing and suction integrated mechanism 3 and an anti-escape dust suction mechanism 4. In this embodiment, there are two anti-escape dust suction mechanisms 4. The blowing and suction integrated mechanism 3 is located in the middle of the support mechanism 1, and the two anti-escape dust suction mechanisms 4 are symmetrically arranged on both sides of the blowing and suction integrated mechanism 3. When the conveyor belts 2 are wrapped around the support mechanism 1, they pass through the interior of the blowing and suction integrated mechanism 3 and the anti-escape dust suction mechanism 4 respectively, and form a receiving space 5 under the combined support of the blowing and suction integrated mechanism 3 and the anti-escape dust suction mechanism 4. The integrated blowing and suction mechanism 3 includes a frame 30, a first drive device 31, a second drive device 32, a mounting shaft 34, a transmission component 35, a connecting bearing 36, a rotary dust blowing assembly 38, and a spiral dust suction assembly 39. The frame 30 includes a limiting rod 301 for limiting the conveyor belt 2; specifically, the output belt passes over the limiting rod 301. In this embodiment, both the first drive device 31 and the second drive device 32 are servo motors, the transmission component 35 is a gear belt, and the output end of the second drive device 32 is equipped with a drive gear 33 that cooperates with the transmission component 35. The rotary dust blowing assembly 38 and the spiral dust suction assembly 39 are mounted on the frame 30 and extend into the receiving space 5, where they rotate. Specifically, the rotary dust blowing assembly 38 and the spiral dust suction assembly 39 are coaxially sleeved on the mounting shaft 34. 4. The first drive device 31 is located at the end of the mounting shaft 34 via a reduction gearbox and is connected to the rotary dust blowing assembly 38 via the mounting shaft 34. The first drive device 31 drives the mounting shaft 34 to rotate, which in turn drives the rotary dust blowing assembly 38 to rotate 360 ​​degrees. The end of the mounting shaft 34 is connected to a rotatable air supply rotary joint 37. The air supply rotary joint 37 connects to the rotary dust blowing assembly 38 through the through hole 342 on the inner cavity 341 of the mounting shaft 34. The air supply rotary joint 37 connects to the compressed air source, so that the compressed air enters the cavity 341 and then flows from the rotary dust blowing assembly 38 to the surface of the object or parts to be cleaned. A 360-degree rotating output airflow field without dead angles is formed above the object or parts to be cleaned, which powerfully and evenly blows up the dust on the surface of the object and makes it disperse. The second drive unit 32 is located on one side of the frame 30 and connected to the spiral dust collection assembly 39 via the transmission component 35. The connecting bearing 36 is fitted onto the mounting shaft 34 with an interference fit. The mounting seat 392 inside the spiral dust collection assembly 39 is connected to the mounting shaft 34 via the connecting bearing 36. Therefore, the rotation of the rotary dust blowing assembly 38 is not transmitted to the spiral dust collection assembly 39, and the rotation of the two is independent. Specifically, under the drive of the second drive unit 32, the spiral dust collection assembly 39 forms a concentrated centripetal suction flow field. This centripetal suction flow field cooperates with the rotary output airflow field to instantly capture and suck up the dust that has just been blown up before it spreads, and transport it to the external negative pressure dust collector (not shown in the figure) through the pipeline. This coaxial integrated design of "blowing and sucking at the same time" fundamentally avoids the secondary re-entrainment of dust and achieves efficient dust removal.

[0021] In a preferred embodiment, the support mechanism 1 further includes two support rods 10, two transmission rollers 11, and two electrostatic rods 13. The two transmission rollers 11 are respectively disposed at both ends of the two support rods 10 through rotating shaft holes 12. The two electrostatic rods 13 are respectively disposed at adjacent positions of the two transmission rollers 11 at both ends of the support rods 10, and their ends are respectively connected to the support rods 10 for fixed installation. In addition, one end of the support mechanism 1 is also provided with a power motor 14 connected to one of the transmission rollers 11. The connection structure between the power motor 14 and the transmission roller 11 is the prior art. The transmission roller 11 is driven to rotate by the power motor 14 to drive the conveyor belt 2 to rotate.

[0022] In a preferred embodiment, a cavity 341 is formed inside the mounting shaft 34. One end of the cavity 341 is connected to a rotatable gas delivery rotary joint 37 to input gas. The side wall of the cavity 341 has a plurality of through holes 342 evenly distributed radially. In this embodiment, three through holes 342 are used as an example. The through holes 342 are connected to the vent holes reserved on the gas delivery adapter block 380 so that the straight connector 388 installed in the vent holes can output compressed gas.

[0023] In a preferred embodiment, the rotary dust blowing assembly 38 includes a rotary auxiliary module, a straight connector 388, an air pipe 389, and a blower nozzle 390. The air supply adapter block 380 of the rotary auxiliary module has an air vent on its outer periphery, and the straight connector 388 is installed in the air vent. One end of the air pipe 389 is connected to the straight connector 388, and the other end of the air pipe 389 is connected to the blower nozzle 390. During operation, compressed air is ejected at high speed from these circumferentially distributed blower nozzles 390, causing the dust on the surface of the dust removal object to be blown up.

[0024] In a preferred embodiment, the rotating auxiliary module includes an air delivery adapter block 380, a rotating disk 381, a rotating support plate 382, ​​and an air guide module 383. The rotating disk 381 is disposed at the lower end of the air delivery adapter block 380. One end of the rotating support plate 382 is connected to the rotating disk 381, and the other end is connected to the air nozzle 390. The air guide module 383 is disposed at the end of the rotating support plate 382 adjacent to the air nozzle 390 to increase the robustness of the rotating dust blowing assembly 38.

[0025] In a preferred embodiment, the air guide module 383 includes an air guide horn tube 385 and a mounting block 384. One end of the mounting block 384 is fixed to the rotating support plate 382. The mounting block 384 is inclinedly disposed on the upper surface of the rotating support plate 382. The air guide horn tube 385 is mounted on the other end of the mounting block 384. The air guide horn tube 385 is an integral structure, which includes a horn mouth 386 and a guide tube 387.

[0026] In a preferred embodiment, the air guide horn 385 is fixed by the mounting block 384 in a spatially composite inclined manner, with its axis set at an angle of 15° to 45° with the horizontal plane. At the same time, the projection of this axis on the horizontal plane forms an angle with the direction of the rotation radius (i.e., it is not blown out radially). This specific structure allows the ejected high-speed airflow to combine into a spiral rotation structure with the horn 386 tilting downward and the guide tube 387 facing the spiral dust collection assembly 39 when the assembly rotates, thereby forming a cyclone airflow that helps to collect large dust particles and effectively guides them to the spiral dust collection assembly 39.

[0027] In a preferred embodiment, the spiral suction assembly 39 includes a spiral suction fan blade 391, a mounting base 392, and a driven gear 393. The spiral suction fan blade 391 is an integrated three-blade structure. During installation, the spiral suction fan blade 391 is fixed to the lower end of the mounting base 392 by screws, and the driven gear 393 is fixed to the upper end of the mounting base 392 by screws. The driven gear 393 is connected to the driving gear 33 of the second drive device 32 through a transmission member 35, so that the driving gear 393 of the second drive device 32 drives the transmission member 35 to move the driven gear 393. The wheel 393 rotates, thereby causing the entire spiral vacuum assembly 39 to rotate. The mounting base 392 is internally connected to the mounting shaft 34 via a connecting bearing 36. Specifically, the mounting shaft 34 is sequentially inserted into the driven gear 393, the mounting base 392, and the spiral vacuum fan blade 391, and is rotatably connected to the mounting base 392 via the connecting bearing 36. The connecting bearing 36 on the mounting shaft 34 ensures that the rotation of the spiral vacuum assembly 39 does not interfere with the rotation of the mounting shaft 34, thereby achieving the purpose of coaxial independent drive of the rotary dust blowing assembly 38 and the spiral vacuum assembly 39.

[0028] In a preferred embodiment, the anti-escape dust collection mechanism 4 includes a limiting roller 41, a dust collection fan 42, and a support bracket 40. The number of dust collection fans 42 is one or more and they are installed on the upper end of the support bracket 40. The limiting roller 41 is located on the side end of the support bracket 40. The conveyor belt 2 passes over the limiting roller 41. The dust collection fan 42 of the anti-escape dust collection mechanism 4 generates an upward airflow to completely remove any small amount of light dust that may escape and transport it to an external negative pressure dust collector (not shown) for collection, ensuring that the dust removal object enters the next production process in an extremely clean state.

[0029] On the other hand, this embodiment also provides a dust removal method that integrates blowing and suction. First, the blowing and suction integrated mechanism 3 set inside the support mechanism 1 and the anti-escape dust suction mechanism 4 set on both sides of the support mechanism 1 form a dust removal area. The dust removal object enters the dust removal area from the entrance of the dust removal area. When the object to be dusted enters the dust removal area, the coaxially arranged rotary dust blowing assembly 38 and spiral dust suction assembly 39 perform dust removal and dust suction respectively. The airflow output from the nozzle 390 of the rotating rotary dust blowing assembly 38 forms a rotating output airflow field that blows up the pollutants attached to the surface of the object. The pollutants blown up by the airflow are sucked up by the negative pressure centripetal suction field formed by the rotating spiral dust suction assembly 39 located at the center of the rotating output airflow field and transported to the external negative pressure dust collector for collection. At the same time, the air guide module 383 located adjacent to the air nozzle 390 captures pollutants and guides them to the spiral dust collection assembly 39, while the escape prevention dust collection mechanism 4 on both sides captures pollutants escaping towards the outlet and inlet on both sides of the dust collection area. After dust removal is completed, the dust-removed object is processed by the blowing and suction integrated mechanism 3 and then enters the next process from the outlet of the dust removal area.

[0030] In summary, by coaxially arranging the rotary dust blowing assembly and the spiral dust suction assembly, and then independently cooperating with the first and second drive devices respectively, a compact and efficient "blowing and suction integrated" structure is formed. Specifically, compressed air is input into the mounting shaft through the rotary air supply connector. The compressed air is then input into the rotary dust blowing assembly. When the rotary dust blowing assembly blows pollutants from the surface of the object being dusted, the spiral dust suction assembly, which rotates coaxially with it, immediately generates a strong local negative pressure at the moment the dust floats up, directly sucking it in and collecting it. In addition, the anti-escape dust suction mechanism located on both sides of the integrated blowing and suction mechanism can capture any small amount of drifting pollutants that may escape from the core working area. The integrated blowing and suction mechanism and the anti-escape dust suction mechanism together constitute a multi-combination dust removal environment, which minimizes the spread of pollutants to the outside of the equipment and protects the cleanliness of the overall production environment.

[0031] Although embodiments of the present invention have been shown above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications and variations to the above embodiments, but such modifications are all included within the broad scope of the foregoing disclosure, drawings and claims.
