Description

Technical Field

[0001] This invention belongs to the technical field of dust removal equipment, and in particular relates to an ultrasonic dust removal device for long workpieces that uses positive and negative pressure coordination. Background Technology

[0002] Ultrasonic dust removal equipment typically consists of an ultrasonic generation system, an airflow system, a collection system, and a control system. Dry ultrasonic dust removal equipment uses a blower to supply clean gas to the ultrasonic generation chamber, which in turn generates ultrasonic waves with the help of a transducer. Then, the airflow system, combined with the vacuum suction generated by the central cavity, sucks away the dust.

[0003] For example, Chinese patent CN220697672U discloses a rotary dry ultrasonic dust collector and cleaning dust removal equipment. By designing the air outlet to rotate at high speed, ultrasonic waves and high-speed airflow are diffused in all directions through the high-speed rotating air outlet to achieve a dust blowing effect.

[0004] However, when traditional single-power dust removal equipment is used to process long workpieces (such as those exceeding 2 meters), the dust removal effect at the end of the workpiece often drops sharply due to wind pressure attenuation or insufficient wind power, making it impossible to achieve uniform and efficient cleaning along the entire length. In precision manufacturing (such as electronics, optics, medical fields), the dust removal process itself cannot generate secondary pollution; traditional single-stage filtration systems are difficult to effectively capture submicron dust and cannot meet the requirements of high cleanliness (such as Class 10,000) production environments. High-pressure, high-volume fans generate strong aerodynamic noise (turbulence noise, eddy noise) and mechanical vibration noise during operation, usually exceeding 85dB, causing serious noise pollution to the working environment and affecting employee health and communication.

[0005] Based on this, the present invention designs an ultrasonic dust removal device for long workpieces with positive and negative pressure coordination to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an ultrasonic dust removal device for long workpieces with positive and negative pressure synergy, which aims to solve the technical problems of traditional ultrasonic dust removal devices in the prior art being unable to effectively capture submicron-level dust, failing to meet the requirements of high-cleanliness production environments, and causing noise pollution.

[0010] Furthermore, the cylindrical silencing assembly includes a silencing box, a silencing baffle, a perforated cylinder, a perforated plate, and an air outlet duct.

[0013] Furthermore, the wide-width dust removal head includes a mounting frame, a wide-width positive pressure pipeline, a negative pressure suction pipe, and a combined dust removal module.

[0015] The above-mentioned technical solutions of the ultrasonic dust removal equipment for long workpieces with positive and negative pressure coordination provided in the embodiments of the present invention have at least one of the following technical effects: 1. The system utilizes a dual-powered design with both positive and negative pressure fans working in tandem. The positive pressure fan provides a stable and powerful positive air source to the wide-width dust removal head, effectively breaking down and removing fine dust adhering to the workpiece surface. Simultaneously, the negative pressure fan creates a strong negative pressure suction field, instantly and efficiently removing the removed dust. This synergistic positive and negative pressure airflow design, combined with the wide-width dust removal head, ensures uniform and stable dust removal energy from the beginning to the end of the workpiece. 2. Simultaneously, the positive pressure air source is filtered twice through a dual filtration assembly to ensure the cleanliness of the positive pressure air source used for dust removal; a series dual filtration system is integrated in the negative pressure recovery path through a primary filtration assembly and a secondary filtration assembly. The dust-laden airflow drawn in by the negative pressure first passes through the primary filter to intercept larger dust particles and debris, thereby protecting the core filtration structure at the back end; this achieves step-by-step and deep purification of dust, effectively preventing secondary pollution caused by dust removal dust; 3. By setting up cylindrical silencing components and cylindrical noise reduction modules, the positive and negative pressure airflows are silenced, effectively suppressing the core noise source without significantly increasing wind resistance or affecting the working efficiency of the fan.

[0023] In one embodiment of the present invention, please refer to the accompanying drawings. Figures 1-4 and Figure 10 The ultrasonic dust removal equipment for long workpieces with positive and negative pressure coordination provided in this application includes a housing 1, a positive pressure mechanism 2, a negative pressure module 3, and a wide dust removal head; A positive pressure mechanism 2 is installed on one side of the chassis 1, and a negative pressure module 3 is installed on the other side of the chassis 1; a control terminal 11 is installed on the side of the chassis 1 closest to the positive pressure mechanism 2. like Figure 4 As shown, the positive pressure mechanism 2 includes a positive pressure air inlet module 21, a dual filter assembly 22, a positive pressure fan 23, a cylindrical silencer assembly 24, and a positive pressure air outlet duct 25. The positive pressure fan 23 is fixedly installed inside the casing 1. The positive pressure air inlet module 21, the dual filter assembly 22, and the cylindrical silencer assembly 24 are installed on one side of the casing 1. The positive pressure air outlet duct 25 is fixedly installed on the casing 1. The positive pressure air inlet module 21 is connected to one side of the dual filter assembly 22, and the positive pressure air outlet duct 25 is connected to the other side of the dual filter assembly 22. After the airflow enters through the positive pressure air inlet module 21, it passes through one side of the dual filter assembly 22, and then passes through the cylindrical silencer assembly 24 driven by the positive pressure fan 23 before being discharged from the positive pressure air outlet duct 25. like Figure 3 and Figure 4 As shown, the negative pressure module 3 includes a dust collection pipe 31, a primary filter assembly 32, a negative pressure fan 33, a cylindrical silencer module 34, and a secondary filter assembly 35. The primary filter assembly 32, the cylindrical silencer module 34, and the secondary filter assembly 35 are installed on the other side of the casing 1. The dust collection pipe 31 is fixedly installed on the lower side of the casing 1, and the negative pressure fan 33 is fixedly installed inside the casing 1. The airflow after dust collection enters the interior of the casing 1 through the dust collection pipe 31, and then, after dust removal through the dust collection pipe 31, it passes through the cylindrical silencer module 34 and is discharged after passing through the secondary filter assembly 35 under the drive of the negative pressure fan 33. The positive pressure air outlet duct 25 is connected to the wide dust collector head through a positive pressure pipeline, and the dust collection pipe 31 is connected to the wide dust collector head through a negative pressure pipeline.

[0024] Positive pressure fan 23 is a high-pressure fan, and negative pressure fan 33 is a large-volume fan.

[0025] In this embodiment, when the positive and negative pressure coordinated ultrasonic dust removal equipment for long workpieces is working normally, the external air undergoes preliminary filtration through the positive pressure air inlet module 21 and the dual filter assembly 22. Driven by the positive pressure fan 23, it forms a high-pressure airflow, which is then silenced by the cylindrical silencer assembly 24 and further filtered by the dual filter assembly 22. The air is then transported to the wide-width dust removal head through the positive pressure outlet duct 25 and the positive pressure pipeline. The positive pressure airflow causes the wide-width dust removal head to generate ultrasonic waves, thereby vibrating the dust on the workpiece. The dust-laden airflow then enters the primary filter assembly 32 through the negative pressure pipeline and the dust collection pipe 31, where it is filtered. Dust in the airflow is filtered and cleaned. Then, driven by the negative pressure fan 33, the airflow passes through the cylindrical silencer module 34 for noise reduction, and is filtered again by the secondary filter component 35 before being discharged. During this process, the positive pressure fan 23 and the negative pressure fan 33 work together in a dual-power process. The positive pressure fan 23 provides a stable and powerful positive pressure air source for the wide-width dust removal head, effectively breaking down and peeling off the fine dust adhering to the surface of the workpiece. At the same time, the negative pressure fan 33 forms a powerful negative pressure suction field, which immediately and efficiently removes the peeled dust. By designing a positive and negative pressure air field in conjunction with the wide-width dust removal head, the dust removal energy from the beginning to the end of the workpiece is ensured to be uniform and stable. Simultaneously, the positive pressure air source is filtered twice by the dual filtration component 22 to ensure the cleanliness of the positive pressure air source used for dust removal; a series dual filtration system is integrated in the negative pressure recovery path by the primary filtration component 32 and the secondary filtration component 35. The dust-laden airflow drawn in by the negative pressure first passes through the primary filter to intercept larger dust and debris particles, thereby protecting the core filtration structure at the back end; this achieves step-by-step and deep purification of dust, effectively preventing secondary pollution caused by dust removal. By setting up the cylindrical silencing component 24 and the cylindrical silencing module 34, the positive and negative pressure airflows are silenced, and the core noise source is effectively suppressed without significantly increasing wind resistance or affecting the working efficiency of the fan.

Filter chambers 321 are distributed on the lower side of the housing 1. A negative pressure relief port 323 is provided on one side of the filter chamber 321. Multiple filter cartridges 322 are fixedly installed inside the filter chamber 321. The dust collection pipe 31 is connected to the filter chamber 321. Inside the housing 1, a partition plate 324 is fixedly installed between the filter cartridges 322 and the negative pressure fan 33. A connecting pipe 325 that connects the filter cartridges 322 and the negative pressure fan 33 is fixedly installed on the partition plate 324. The cylindrical silencing module 34 includes a second silencing box 341, a second mesh cylinder 342, a second air outlet duct 343, and a second sound-absorbing baffle 345. The second silencing box 341 is fixedly installed on the chassis 1. Multiple sound-absorbing baffles 345 are fixedly installed inside the second silencing box 341, and multiple mesh cylinders 342 are fixedly installed inside the second silencing box 341. An airflow inlet chamber 344 connected to the negative pressure fan 33 is distributed on one side of the second silencing box 341. An air outlet duct 343 connected to the secondary filter assembly 35 is fixedly installed on the other side of the second silencing box 341. The secondary filtration assembly 35 includes a mounting box 351 and a filter element 352. The mounting box 351 is fixedly mounted on the chassis 1, and the filter element 352 is fixedly installed inside the mounting box 351.

[0028] like Figure 10 As shown, the wide-width dust removal head includes a mounting frame 41, a wide-width positive pressure pipeline 42, a negative pressure suction pipe 44, and a combined dust removal module. The wide-width positive pressure pipeline 42 and the negative pressure suction pipe 44 are fixedly installed on the mounting frame 41. The wide-width positive pressure pipeline 42 is connected to the positive pressure air outlet pipe 25 through a positive pressure pipe, and the negative pressure suction pipe 44 is connected to the dust collection pipe 31 through a negative pressure pipe.

[0029] In this embodiment, when the chassis 1, positive pressure mechanism 2, negative pressure module 3, and wide-width dust collector are working normally, the external air is initially filtered by the pre-filter 222 and then sequentially passes through the air inlet chamber 211 and air inlet pipe 212 before being driven by the positive pressure fan 23 to form a high-pressure airflow. The high-pressure airflow enters the silencer box 241 through the airflow inlet chamber 243, and then flows sequentially through the mesh cylinder 244 to different chambers separated by the silencer baffle 242. Inside the silencer box 241, the airflow is guided by the mesh cylinder 244 and the mesh plate 245, and separated by the silencer baffle 242, so that the airflow generates high-efficiency attenuation of noise at specific frequencies through multiple mechanisms such as sound wave resonance, reflection, interference, absorption, and energy dissipation, achieving a significant noise reduction effect. The silenced airflow flows to the high-efficiency filter 223 through the air outlet pipe 246 and the air outlet chamber 247. The airflow undergoes a second filtration inside the chamber, then flows through a positive pressure pipe into a wide positive pressure pipe 42, where it is blown out through multiple ultrasonic dust removal heads 43. The high-pressure airflow drives the ultrasonic dust removal heads 43 to generate high-frequency ultrasonic waves, thus cleaning long workpieces. Subsequently, the airflow carrying dust flows through a wide negative pressure pipe 45 into a negative pressure suction pipe 44, where it converges. Then, it flows through a negative pressure pipe and a dust collection pipe 31 into a filter chamber 321. After being filtered by a filter cartridge 322, it passes through a connecting pipe 325 on a partition plate 324. The airflow is driven by a negative pressure fan 33 through an airflow inlet chamber 344 into a silencer box 341. It then flows through a mesh cylinder 342 into multiple chambers separated by a sound-absorbing partition plate 345 before being discharged from an outlet pipe 343, achieving noise reduction. After being silenced, the airflow is filtered by a filter element 352 in a mounting box 351 and then discharged through a dust collection outlet 353.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
