Description

Technical Field

[0001] The present invention relates to the field of cleaning equipment, in particular to a tornado forming device and a tornado cleaning system. Background Art

[0002] With the upgrading of domestic industries, more and more automotive parts and precision electromechanical products require non-contact cleaning during assembly, such as the three-electric system, headlights, automotive instruments, controllers, PCBAs, and other components. Currently, the non-contact dust removal and blowing devices on the market mainly include air knives, electrostatic dust removal boxes, and traditional typhoon cleaning devices.

[0003] Air knives lack pulsed airflow, resulting in poor cleaning performance. Furthermore, their large size prevents them from reaching the interior of cavities, making them difficult to use for complex curved surfaces and non-standard components like automotive parts. Electrostatic precipitators (ESPs) use ionized air from an ionized air wand to dissipate static electricity while simultaneously removing dust. However, this dust remains within the ESP, potentially causing secondary contamination and compromising cleaning effectiveness. Traditional typhoon cleaning systems utilize compressed air to simultaneously rotate and blow air through the nozzle. However, the speed is fixed and cannot be adjusted, and fluctuations in air pressure affect the speed and dust pressure, making optimal process parameters and cleaning performance suboptimal in practical applications. Because the suction chamber opening corresponds to an open space, the negative suction pressure is insufficient, preventing complete removal of foreign matter and resulting in limited cleaning performance. Traditional typhoon systems typically have an effective cleaning distance of less than 50 mm, while many automotive and industrial core components have deep cavities exceeding 50 mm, making it difficult to achieve the desired cleaning performance. Summary of the Invention

[0004] In view of the problems that the cleaning devices mentioned above or in the prior art cannot generate pulsed airflow, cannot accurately eliminate static electricity, easily cause secondary pollution, and cannot effectively clean deep cavity parts, the present invention is proposed.

[0005] Therefore, one of the objects of the present invention is to provide a tornado forming device.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a tornado forming device, comprising an installation unit, a tornado forming unit, and a control module.

[0007] Among them, the tornado forming unit includes a channel assembly arranged on the mounting unit, an axial power assembly arranged at the dust collection end of the channel assembly, and a tangential power assembly arranged at the connection end between the channel assembly and the equipment to be cleaned; and the control module includes an electrostatic sensor arranged on the mounting unit, and an ion wind rod connected to the tornado forming unit.

[0014] As a preferred solution of the tornado forming device of the present invention, the ion wind rods are arranged on both sides of the tornado forming chamber.

[0015] The beneficial effects of the tornado-forming device of the present invention are as follows: by setting up a tornado-forming unit, the effect of transforming the axial straight airflow disturbance into a tornado is achieved. The strong air vortex formed by the micro-tornado can roll up foreign matter on the cleaning surface that is far away. Because of the pressure difference between the eye of the tornado and the atmosphere, the dust is rolled up with the tornado vortex and will not escape, thus eliminating the secondary pollution of the dust and achieving a non-contact deep cavity cleaning effect. At the same time, the control module realizes the precise elimination of closed-loop static electricity, and the dynamic control technology of the control module is used to effectively eliminate static electricity, avoid high voltage breakdown of the product to be cleaned, and save energy at the same time. For non-planar products, a strong upward vortex is formed through an artificial tornado to form a fluid rising channel, which can avoid interference with the structure of the product and achieve a good cleaning effect. At the same time, due to the strong entrainment effect of the tornado, metal chips, fibers, other foreign matter, dust, etc. can be drawn into the dust suction chamber and then completely extracted by the dust collection pipe without causing secondary pollution.

[0016] A second object of the present invention is to provide a tornado cleaning system.

[0017] In order to solve the above technical problems, the present invention provides the following technical solutions: a tornado cleaning system based on the tornado forming device of the above technical solution, further comprising a filter dust collecting box arranged at the dust collection end of the tornado forming unit, an electrical control box arranged on the filter dust collecting box, and a secondary dust extraction box arranged on the electrical control box.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Example 1, reference Figures 1 to 4, is the first embodiment of the present invention, which provides a tornado-forming device that can form a tornado-like pulse airflow on a traditional cleaning device, thereby improving the cleaning effect of deep-cavity parts. It includes a tornado-forming device, including an installation unit 1, a tornado-forming unit 2, and a control module. Among them, the installation unit 1 is used to set the tornado-forming device at one end of the complete cleaning system close to the device to be cleaned. Preferably, this installation unit 1 can generate a corresponding tornado pulse airflow when it is set on any pipeline, thereby achieving a turbulent pressurization effect on the fluid inside the pipeline. The tornado-forming unit 2 achieves the effect of transforming the axial straight airflow disturbance into a tornado from the two perspectives of the change in the cross-sectional area of ​​the pipeline and the superposition of the power source. The strong air vortex formed by the micro-tornado can roll up foreign matter on the cleaning surface that is far away. Because of the pressure difference between the tornado eye and the atmosphere, dust is rolled up with the tornado vortex and will not escape, eliminating secondary pollution of dust and achieving an excellent non-contact cleaning effect.

[0035] The tornado-forming unit 2 comprises a channel assembly 21 mounted on the mounting unit 1, an axial power assembly 22 mounted at the dust collection end of the channel assembly 21, and a tangential power assembly 23 mounted at the end where the channel assembly 21 connects to the equipment to be cleaned. A Laval duct with a shrinking cross-sectional area is provided within the channel assembly 21. The airflow breaks the speed of sound at the critical point of the Laval duct. Due to the Coanda effect, the flow velocity continues to increase in the outlet expansion section of the Laval duct, reducing the pressure inside the channel assembly 21. This creates a significant pressure differential with atmospheric pressure near the dust collection outlet of the channel assembly 21, forming an artificial tornado eye at the Laval duct. The axial power component 22 provides negative pressure initial power, and the tangential power component 23 blows out compressed air tangentially from the rotating shaft 223 while rotating at high speed, providing tangential power for the air vortex rotation, and finally achieving the effect of transforming the axial linear airflow disturbance into a tornado. The strong air vortex formed by the micro tornado can roll up foreign objects on the cleaning surface at a distance. Because of the pressure difference between the tornado eye and the atmosphere, the dust is rolled up with the tornado vortex and will not escape, eliminating secondary pollution of dust and achieving a non-contact cleaning effect.

[0036] And, the control module includes an electrostatic sensor 3 provided on the mounting unit 1, and an ion wind rod 4 connected to the tornado forming unit 2. The main function of the control module is an intelligent feedback system based on real-time electrostatic detection. It monitors the charge on the target surface through sensors, dynamically adjusts the output frequency and intensity of the ion generator, and achieves accurate neutralization of static electricity to prevent dust from being adsorbed on the inner wall of the cleaning equipment due to static electricity. Three-dimensional perception layer: Equipped with a 16-channel non-contact electrostatic sensor array, the electrostatic sensor 3 contacts the working surface of the cleaning equipment through the mounting unit 1, and establishes a connection with the working surface of the cleaning equipment in the X / Y / Z axes. The temperature and humidity sensor and the airflow velocity sensor are integrated inside the control module, and a 5MHz high-frequency sampling circuit is used to achieve real-time update of the charge at the 50ms level. Utilizing the edge computing hub, an embedded FPGA is set up to process real-time signals, process multiple sets of sensor data in parallel, and deploy AI inference engines, such as the TensorRT acceleration framework. Dual redundant CAN bus communications ensure the transmission of control instructions. The ion wind rod 4 is arranged on both sides of the tornado forming chamber 11. A high-frequency resonant circuit is provided in the ion wind rod 4 with an adjustable frequency range of 20-100kHz. The ion wind rod 4 has 8-level intensity control graded pulse modulation, adjustable by ±15kV. The ion wind rod 4 has a bipolar alternating output, thereby achieving the effect of positive / negative ion dynamic balance control, and finally realizing a closed-loop static electricity precision elimination device.

[0037] The dynamic control technology of the control module effectively eliminates static electricity, preventing high voltage from damaging the product being cleaned, and conserving energy. For non-flat surfaces, an artificial tornado creates a powerful upward vortex, forming a fluid upward path that avoids interference with the product structure and achieves excellent cleaning results. The tornado's powerful entrainment effect also draws metal shavings, fibers, other foreign matter, and dust into the suction chamber, where they are completely removed through the dust collection duct, preventing secondary contamination.

[0038] During use, the tornado-forming device is connected to the cleaning pipe of the deep cavity equipment where the tornado vortex is to be formed. The Laval pipe with a reduced cross-sectional area is set in the channel component 21 to form an artificial tornado eye. The axial power component 22 provides the initial power of negative pressure, and the tangential power component 23 blows compressed air tangentially from the hollow rotating shaft 223 while rotating at high speed, providing tangential power for the rotation of the air vortex. Ultimately, the axial straight air flow disturbance is transformed into a tornado, forming a miniature tornado. The strong air vortex of the miniature tornado can roll up foreign matter on the cleaning surface at a distance. Due to the pressure difference between the tornado eye and the atmosphere, dust is rolled up with the tornado vortex and will not escape, eliminating secondary contamination of dust and achieving a non-contact cleaning effect. The above axial power component 22 and tangential power component 23 speed, blowing pressure, blowing flow, etc. are all precisely controlled by the control module. Micro-tornadoes of different intensities can be formed according to the size of the product to be cleaned, simulation results and experimental parameters, effectively cleaning while avoiding damage to the product or device. At the same time, the dynamic control technology of the control module is used to effectively eliminate static electricity, avoid high voltage breakdown of the product to be cleaned, and save energy.

[0039] Example 2, reference Figures 1 to 10 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a specific structure for the tornado-forming unit 2 in a tornado-forming device. It includes a channel assembly 21, comprising a dust collection pipe 211 mounted on the mounting unit 1, a Laval tube 212 mounted on the dust collection pipe 211, and a device-to-be-cleaned connection pipe 213 mounted on the Laval tube 212. The dust collection pipe 211 is connected to an extension pipe and ultimately mounted on the cleaning electrical control box. The Laval tube 212 is a pressurized pipe with a rapidly decreasing cross-section, which forms a tornado. The device-to-be-cleaned connection pipe 213 connects to the deep-cavity device to be cleaned and also serves as a connection to the electrostatic sensor 3. As the cross-sectional area of ​​the Laval tube 212 decreases, the airflow breaks the speed of sound at the critical point of the Laval tube. Due to the Coanda effect, the flow rate continues to increase in the outlet expansion section of the Laval tube 212, reducing the internal pressure of the channel assembly 21. A significant pressure differential forms between the pressure at the outlet of the channel assembly 21 near the dust collection end and atmospheric pressure, forming an artificial tornado eye at the Laval tube. A mounting seat for mounting the axial power assembly 22 is provided on the channel assembly 21 .

[0040] Furthermore, the axial power assembly 22 includes a motor 221 mounted on the dust collection pipe 211, a rotating shaft 223 mounted on the motor 221, and a negative pressure impeller 222 mounted on the rotating shaft 223. The rotating shaft 223 is coaxially arranged with the channel assembly 21. The motor 221 is configured as an ultra-high-speed motor, capable of driving the negative pressure impeller 222 to rotate at high speed and provide axial power. The rotating shaft 223 is configured as a hollow shaft, capable of cooperating with the tangential power assembly 23 to tangentially blow compressed air, providing tangential power for the air vortex rotation.

[0041] Furthermore, the tangential power assembly 23 includes a nozzle 231 mounted on the rotating shaft 223, a nozzle mounting base 232 mounted on the nozzle 231, and a tangential air blowing nozzle 233 mounted on the nozzle mounting base 232. Driven by the motor 221, the nozzle 231 rotates at high speed, while the rotating shaft 223 blows compressed air tangentially, providing tangential power for the air vortex rotation. This ultimately achieves the effect of transforming the axial linear airflow disturbance into a tornado. The powerful air vortex formed by the miniature tornado can sweep up foreign matter on the cleaning surface at a distance. Due to the pressure difference between the tornado eye and the atmosphere, dust is swept up with the tornado vortex and does not escape, eliminating secondary dust contamination and achieving a non-contact cleaning effect. There are multiple groups of nozzle mounts 232 on the nozzle 231, including nozzle mount 1 2321 and nozzle mount 2 2322 coaxially arranged with nozzle mount 1 2321. The arrangement of nozzle mount 1 2321 and nozzle mount 2 2322 facilitates providing uniform tangential force inside the channel assembly 21 to form a tornado eye.

[0042] Furthermore, an axial dust-raising nozzle 234 is provided on the nozzle mounting seat 232, so as to facilitate cleaning the interior of the device when the entire device switches from exhaust to intake in reverse operation.

[0043] Furthermore, the nozzle 231 is provided with an axial spray hole 2311 to facilitate the spraying operation inside the deep cavity device.

[0044] Furthermore, the installation unit 1 includes a tornado forming chamber 11 and a mounting flange 12 disposed on the tornado forming chamber 11 and connected to the channel assembly 21 . The mounting flange 12 arranges multiple groups of channel assemblies 21 in parallel on the tornado forming chamber 11 .

[0045] The rest of the structure is the same as that of Example 1.

[0046] During use, a Laval duct with a shrinking cross-sectional area is provided within the channel assembly 21. The airflow breaks the speed of sound at the critical point of the Laval duct. Due to the Coanda effect, the flow rate continues to increase in the outlet expansion section of the Laval duct, and the internal pressure of the channel assembly 21 decreases. A huge pressure difference is formed with the atmospheric pressure near the outlet of the channel assembly 21 near the dust collection end, forming an artificial tornado eye in the Laval duct. The axial power assembly 22 provides the initial negative pressure power, and the tangential power assembly 23 blows compressed air tangentially from the rotating shaft 223 while rotating at high speed, providing tangential power for the air vortex to rotate. This ultimately achieves the effect of transforming the axial linear airflow disturbance into a tornado. The powerful air vortex formed by the miniature tornado can sweep up foreign matter on the cleaning surface at a distance. Due to the pressure difference between the tornado eye and the atmosphere, dust is swept up with the tornado vortex and does not escape, eliminating secondary dust contamination and achieving an excellent non-contact cleaning effect. The rotation speed, blowing pressure, blowing flow rate, etc. of the above-mentioned axial power assembly 22 and tangential power assembly 23 are all precisely controlled by the control module, and micro-tornadoes of different intensities can be formed according to the size of the product to be cleaned, the simulation results and the experimental parameters, which can effectively clean while avoiding damage to the product or device. At the same time, the dynamic control technology of the control module is used to effectively eliminate static electricity, avoid high voltage breakdown of the product to be cleaned, and achieve the effect of reducing energy consumption. For non-planar products, artificial tornadoes are used to form strong upward vortices and constitute fluid rising channels, which can avoid interference with the structure of the product and achieve a good cleaning effect. At the same time, due to the strong entrainment effect of the tornado, metal chips, fibers, other foreign matter, dust, etc. can be drawn into the dust suction chamber and then completely extracted by the dust collection pipe without causing secondary pollution.

[0047] Example 3, reference Figure 11 This is the third embodiment of the present invention. Based on the previous embodiment, a tornado cleaning system is provided to solve the problems that the existing cleaning device cannot generate pulsed airflow, static electricity cannot accurately eliminate dust, and is prone to secondary pollution, and cannot effectively clean deep cavity parts.

[0048] The tornado cleaning system includes a filter dust box 5 arranged at the dust collection end of the tornado forming unit 2, an electrical control box 6 arranged on the filter dust box 5, and a secondary dust extraction box 7 arranged on the electrical control box 6, to realize a complete cleaning and dust removal work process. The secondary dust extraction box 7 can perform secondary dust extraction on the air passing through the filter dust box 5, further reducing the amount of dust residue inside the cleaning system.

[0049] Furthermore, the electric control box 6 is provided with a pneumatic control module 8, which can adjust the cleaning status of the entire equipment in real time.

[0050] During use, the tornado cleaning system is connected to the deep cavity equipment to be cleaned, and the electrostatic sensor is set on the equipment to be cleaned. The system is started through the electrical control box 6. A Laval pipe with a reduced cross-sectional area is set in the channel component 21. The airflow breaks through the speed of sound at the critical point of the Laval pipe. According to the Coanda effect, the flow velocity continues to increase in the air outlet expansion section of the Laval pipe, and the internal pressure of the channel component 21 decreases. A huge pressure difference is formed with the atmospheric pressure at the outlet of the channel component 21 near the dust collection end, that is, an artificial tornado eye is formed at the Laval pipe. The axial power assembly 22 provides the initial power of negative pressure, and the tangential power assembly 23 blows out compressed air tangentially from the rotating shaft 223 while rotating at high speed, providing tangential power for the rotation of the air vortex, and finally achieving the effect of turning the axial straight airflow disturbance into a tornado. The strong air vortex formed by the micro-tornado can roll up foreign matter on the cleaning surface at a distance. Because of the pressure difference between the tornado eye and the atmosphere, dust is rolled up with the tornado vortex and will not escape, eliminating the secondary pollution of dust, and setting a filter dust collection box 5 to realize the centralized processing of multiple groups of tornado cleaning devices, and finally achieving a non-contact cleaning effect. The above-mentioned axial power assembly 22 and tangential power assembly 23 rotation speed, blowing pressure, blowing flow, etc. are all precisely controlled by the control module, and micro-tornadoes of different intensities can be formed according to the size of the product to be cleaned, the simulation results and the experimental parameters, effectively cleaning while avoiding damage to the product or device. At the same time, the dynamic control technology of the control module is used to effectively eliminate static electricity, avoid high voltage breakdown of the product to be cleaned, and save energy. For non-flat surfaces, the artificial tornado creates a powerful upward vortex, forming an upward fluid channel that avoids interference with the product structure and achieves excellent cleaning results. At the same time, the tornado's powerful entrainment effect can draw metal shavings, fibers, other foreign matter, and dust into the suction chamber, where they are completely removed through the dust collection duct, preventing secondary pollution.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
