Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable cleaning technology, specifically to a method and cleaning system for the degradation of pesticide residues in fruits and vegetables based on ultrasonic synergistic water electrolysis. Background Technology

[0002] Various fruit and vegetable cleaning devices have emerged in the current technology. For example, some devices use ultrasonic cleaning technology, utilizing the cavitation effect generated by ultrasound in water to peel off and degrade pesticide residues; others use water electrolysis technology, generating highly oxidizing active substances (such as hypochlorous acid and hydroxyl radicals) through electrolysis to oxidize and decompose pesticide molecules. However, each of these individual technologies has its own limitations: while ultrasonic cleaning has a strong cavitation effect, its range of action is limited, and prolonged use may damage the surface of fruits and vegetables; water electrolysis is limited by the mass transfer efficiency of the active substances, and without good water flow disturbance, it is difficult to achieve sufficient contact with the surface of fruits and vegetables.

[0003] To overcome the shortcomings of single technologies, some existing technologies attempt to combine ultrasonic and water electrolysis technologies. However, analysis reveals that most of these combinations are simply functional superpositions, i.e., simultaneously placing an ultrasonic generator and an electrolysis module in the same cleaning device, with each operating independently and lacking deep structural integration and functional synergy. Specifically, existing combined technologies have the following deficiencies: First, the water flow within the cleaning chamber is uniform, mostly simple unidirectional or spiral stirring, easily creating dead zones and resulting in uneven distribution of active substances in the electrolyzed water and ultrasonic energy, failing to achieve comprehensive coverage of the fruit and vegetable surface; Second, during the cleaning process, the fruits and vegetables tumble disorderly under the strong water flow, easily colliding with each other or hitting the inner wall of the device, causing skin damage, and preventing them from being stably positioned in the area with the strongest cleaning energy, affecting the uniformity of the cleaning effect; Third, the existing equipment's limiting structure (such as the cleaning basket or partition) lacks linkage with the flow field driving mechanism. The limiting structure only serves a simple fixing function and cannot dynamically adjust the fruits and vegetables, causing a large amount of cleaning energy to be wasted in ineffective space.

[0004] To this end, we propose a method and cleaning system for the degradation of pesticide residues in fruits and vegetables based on ultrasonic-assisted water electrolysis. Summary of the Invention

[0014] An operating method for a fruit and vegetable pesticide residue cleaning system based on ultrasonic synergistic water electrolysis, characterized by comprising the following operating methods: S1: Place the fruits and vegetables inside the first limiting mechanism, connect the second limiting mechanism with the first limiting mechanism, so that the first limiting mechanism and the second limiting mechanism together enclose and form a wrap-around cleaning area, and confine the fruits and vegetables within this area; S2: Inject clean water into the cleaning mechanism and start the drive mechanism. The drive mechanism generates a planetary double vortex coupled stirring flow field, which stirs the clean water inside the cleaning mechanism in multiple dimensions, forming a turbulent flow composed of a central vortex and a surrounding revolving spiral vortex. S3: The drive mechanism drives the first and second limiting mechanisms to change the diameter, so that the wrap-around cleaning area can perform diffusion and squeezing operations on fruits and vegetables, thereby achieving dynamic cleaning of fruits and vegetables. S4: The first electrolysis component of the first limiting mechanism and the second electrolysis component of the second limiting mechanism are activated to electrolyze the water, producing an oxidizing active substance in the electrolyzed water, which then comes into full contact with the surface of the fruits and vegetables under the influence of the planetary double vortex coupled stirring flow field. S5: Activate the ultrasonic vibration component of the second limit mechanism to generate ultrasonic vibration. Through the cavitation and mechanical effects of ultrasound, enhance the mass transfer process of active substances in water electrolysis and directly degrade pesticide residues. S6: Through the synergistic effect of planetary double vortex coupled stirring flow field, electrolytic water active substances and ultrasonic vibration, pesticide residues on the surface of fruits and vegetables are efficiently degraded. After cleaning, the wastewater is discharged through the guide component.

[0015] Compared with existing technologies: The planetary double-vortex coupled stirring flow field of the present invention forms a complex turbulent flow with multiple layers and directions in the washing cylinder through the combined motion of the central vortex and multiple revolving spiral vortices. This flow field can continuously wash the surface of fruits and vegetables from all angles, effectively solving the problem that microscopic dead corners such as depressions and skin crevices on the surface of fruits and vegetables are difficult to clean in traditional washing methods. Through the dynamic adjustment of the first and second limiting mechanisms, the size of the wrap-around cleaning area can be diffused and squeezed with the fruits and vegetables. This design firmly confines the fruits and vegetables within the core energy field composed of electrolytic electrode plates, arc-shaped electrolytic plates, and ultrasonic vibration plates, avoiding the dissipation of active substances in electrolytic water and ultrasonic energy into ineffective spaces. At the same time, the guiding effect of the spiral cotton further guides the water flow and energy to concentrate on the surface of the fruits and vegetables, greatly improving the energy utilization efficiency, thereby achieving a higher pesticide residue degradation rate in a shorter time. By connecting the first and second flexural ribs, the first and second fixed arc plates have a certain degree of elasticity when the diameter changes. At the same time, the spiral cotton, as a buffer layer, can effectively prevent fruits and vegetables from being damaged by rigid collisions with the ultrasonic vibrating plate in the strong flow field. The dynamic diameter adjustment also avoids the disorderly tumbling of fruits and vegetables during the washing process, further reducing the risk of mechanical damage. Attached Figure Description

The outer ends of the second connecting rod 321, the electrolytic electrode plate 322, and the third connecting rod 323 are connected to one end of the first blocking rib 324. The other end of the first blocking rib 324 is connected to the outer wall of another set of second connecting rods 321, electrolytic electrode plates 322, and third connecting rods 323. The first blocking rib 324 can block the gap between the second connecting rod 321, the electrolytic electrode plate 322, and the third connecting rod 323, preventing fruits and vegetables from escaping from the first limiting mechanism 3 and the second limiting mechanism 3. Inside the mechanism 4, the bottom of the first electrolysis component 32 is connected to the first connecting component 33. The inner wall of the first connecting component 33 is connected to the lower end of the outer wall of the bidirectional screw 221 in the drive mechanism 2. Rotation of the bidirectional screw 221 allows for the lifting and lowering of the first connecting component 33. The movement of the first connecting component 33 allows for the pushing and pulling of the first electrolysis component 32, thereby causing the first electrolysis component 32 to push and pull the first telescopic component 31, thus controlling the change in the circular diameter of the first telescopic component 31. The outer wall of the first internal thread block 331 is connected to the bottom of the third connecting rod 323. The inner wall of block 331 is threadedly connected to the lower end of the outer wall of the bidirectional screw 221 in the drive mechanism 2. Through the rotation of the bidirectional screw 221, and in conjunction with the limiting action of the first connecting rod 315 and the first bearing 316, the first internally threaded block 331 can slowly rise and fall at the lower end of the bidirectional screw 221. This slow rising and falling motion of the first internally threaded block 331 allows for a gradual change in the diameter of the circle formed by the first fixed arc plate 311 and the first flexible rib 314. A guide ring 332 is provided at the upper end of the outer wall of the first internally threaded block 331, which supports and limits the bottom center of the second limiting mechanism 4. The second limiting mechanism 4 is connected to the top of the first limiting mechanism 3 and is installed on the upper end of the drive mechanism 2. The second limiting mechanism 4 cleans fruits and vegetables through ultrasonic vibration, water electrolysis, and pressing operations. Through the cooperation of the first limiting mechanism 3, the second limiting mechanism 4, and the drive mechanism 2, it performs a wrap-around agitation and cleaning operation on the fruits and vegetables. The second limiting mechanism 4 includes: a second telescopic component 41, a second fixed arc plate 411, a slide groove 412, an L-shaped block 413, a second flexible rib 414, a fourth connecting rod 415, a second shaft seat 416, a sub-terminal 417, a second electrolysis component 42, a fifth connecting rod 421, a sixth connecting rod 422, a seventh connecting rod 423, an eighth connecting rod 424, and an arc-shaped electrolysis plate 425. The second blocking rib 426, ultrasonic vibration component 43, second internal thread block 431, mounting cylinder 432, ultrasonic vibration plate 433, and spiral cotton 434; the outer side of the second telescopic component 41 is connected to the upper end of the outer wall of the shaft 231 of the drive mechanism 2. Through the lifting and lowering movement of the ultrasonic vibration component 43 and the pushing and pulling operation of the second electrolysis component 42, the second telescopic component 41 can be circularly telescopic, thereby expanding or shrinking the diameter of the second telescopic component 41, and thus controlling the activity space of fruits and vegetables. The top of the second fixed arc plate 411 is provided with a sliding groove 412. The bottom of the second electrolysis component 42 is slidably connected inside the sliding groove 412. The sliding groove 412 can limit and guide the movement of the second electrolysis component 42, so that... When the second electrolysis component 42 moves in a push-pull motion, it can move closer or further away from each other within the slide groove 412, thereby facilitating the change of the circular diameter formed by the second fixed arc plate 411 and the second flexible rib 414. An L-shaped block 413 is provided at the bottom center of the second fixed arc plate 411. The L-shaped block 413 is slidably connected to the inside of the L-shaped groove 312 in the first limiting mechanism 3. Through the connection between the L-shaped block 413 and the L-shaped groove 312, the first telescopic component 31 and the second telescopic component 41 can be detachably installed. The second fixed arc plate 411 is configured in several groups, with the two ends of the several groups of second fixed arc plates 411 connected by the second flexible rib 414, so that the several groups of second fixed arc plates 411 and the several groups of second flexible ribs 414 form a circle. The bottom of the fourth connecting rod 415 is rotatably connected to the middle of the outer wall of the second connecting rod 415. The top of the fourth connecting rod 415 is rotatably connected to the inner end of the second bearing 416. The interior of the second bearing 416 is slidably connected to the upper end of the outer wall of the shaft 231 in the drive mechanism 2. The bottom of the second bearing 416 is contacted by the top of the second retaining ring 234 in the drive mechanism 2. The second retaining ring 234 limits the position of the second bearing 416 to prevent the second limiting mechanism 4 from moving downward continuously. The inner walls of the second bearing 416 are provided with sub-terminals 417 at both ends. The sub-terminals 417 are in contact with the interior of the female terminal 235 in the drive mechanism 2. The circuit is connected through the contact between the female terminal 235 and the sub-terminals 417. The top of the second telescopic component 41 is connected to the bottom of the second electrolysis component 42.The lifting and lowering movement of the ultrasonic vibration component 43 pushes and pulls the second electrolysis component 42, causing it to electrolyze the water at the bottom and simultaneously press the fruits and vegetables, bringing the electrolyzed water into closer contact with them. The top of the fifth connecting rod 421 is rotatably connected to the outer wall of the ultrasonic vibration component 43 via a torsion spring. The bottom of the fifth connecting rod 421 is rotatably connected to the top of the sixth connecting rod 422 via a torsion spring. The bottom of the sixth connecting rod 422 is rotatably connected to the bottom of the seventh connecting rod 423 via a torsion spring. The top of the seventh connecting rod 423 is rotatably connected to the eighth connecting rod 424 via a torsion spring. The bottom of the eighth connecting rod 424 is slidably connected to the inside of the slide groove 412 via a slider. The sixth connecting rod 422 and the seventh connecting rod 423 are connected to the eighth connecting rod 424 via a torsion spring. The connecting rod 423 is connected to the arc-shaped electrolysis plate 425 via a torsion spring. The arc-shaped electrolysis plate 425 can electrolyze the water at the bottom and also press down floating fruits and vegetables. The torsion spring limits the bending angles of the fifth connecting rod 421, sixth connecting rod 422, seventh connecting rod 423, eighth connecting rod 424, and arc-shaped electrolysis plate 425, allowing the ultrasonic vibration component 43 to move up and down. This enables the second electrolysis component 42 to push and pull the circular diameter of the second telescopic component 41. It also allows the fifth connecting rod 421, sixth connecting rod 422, seventh connecting rod 423, eighth connecting rod 424, and arc-shaped electrolysis plate 425 to move during these movements. The angle change causes the arc-shaped electrolysis plate 425 to swing, enabling the arc-shaped electrolysis plate 425 to press the fruits and vegetables. The outer ends of the seventh connecting rod 423 and the eighth connecting rod 424 are connected to one end of the second blocking rib 426. The other end of the second blocking rib 426 is connected to the outer wall of another set of seventh connecting rods 423 and eighth connecting rods 424. The second blocking rib 426 can block the gap between the seventh connecting rod 423 and the eighth connecting rod 424, preventing the fruits and vegetables from escaping the space between the first limiting mechanism 3 and the second limiting mechanism 4. The top of the second electrolysis assembly 42 is connected to the upper perimeter of the outer wall of the ultrasonic vibration assembly 43. The ultrasonic vibration assembly 43 can push and pull the second telescopic assembly 41 and the second electrolysis assembly 42. Simultaneously, the ultrasonic vibration component 43 continuously vibrates the water in the center between the first limiting mechanism 3 and the second limiting mechanism 4 outwards. The outer wall of the second internal threaded block 431 is rotatably connected to the top of the fifth connecting rod 421. The interior of the second internal threaded block 431 is threadedly connected to the upper end of the outer wall of the bidirectional screw 221 in the drive mechanism 2. Through the rotation of the bidirectional screw 221, the second internal threaded block 431 can be raised and lowered, thereby allowing the second internal threaded block 431 to push and pull the second electrolysis component 42 and the second telescopic component 41. Through the rotation of the bidirectional screw 221, the second internal threaded block 431 and the first internal threaded block 331 can move closer or further apart. The bottom of the second internal threaded block 431 is provided with an installation cylinder 432.Ultrasonic vibrating plates 433 are installed around the outer wall of the mounting cylinder 432. These plates vibrate the surrounding water, thus ultrasonically cleaning the fruits and vegetables in the space between the first limiting mechanism 3 and the second limiting mechanism 4. Spiral cotton 434 is installed on the outer wall of the ultrasonic vibrating plates 433. This spiral cotton 434 contacts the fruits and vegetables, preventing damage from collisions. Simultaneously, the spiral cotton 434 also guides the flow of the central water vortex between the first and second limiting mechanisms 3 and 4.

[0019] In practical use, those skilled in the art place fruits and vegetables inside the first limiting mechanism 3, and slide the second shaft seat 416 of the second limiting mechanism 4 onto the upper end of the shaft 231. The inner wall of the second shaft seat 416 is pre-installed with a sub-terminal 417. The second internal threaded block 431 of the ultrasonic vibration assembly 43 forms a threaded engagement with the upper threaded section of the bidirectional screw 221. The L-shaped block 413 at the bottom of the second fixed arc plate 411 is slidably embedded into the L-shaped groove 312 at the top of the first fixed arc plate 311, completing the vertical coaxial connection between the first limiting mechanism 3 and the second limiting mechanism 4. Thus, the first limiting mechanism 3 and the second limiting mechanism 4 together enclose a wrap-around cleaning area, facilitating the limited cleaning of fruits and vegetables. The drain at the right end of the drain ring 113 is then closed. Valve 114 injects clean water into the cleaning cylinder 121 until the water level completely submerges the first limiting mechanism 3 and the second limiting mechanism 4, and installs the cover plate 141 so that the top of the bidirectional screw 221 is embedded in the bottom center of the cover plate 141, and the top of the shaft 231 is embedded in the second rotating groove 143 to form a rotational engagement, completing the equipment assembly and pretreatment. When cleaning is performed, the operator starts the drive motor 211, which drives the first gear 212 to rotate. The first gear 212 drives the second gear 213, which meshes with it, to rotate. Since the second gear 213 simultaneously meshes with the internal gear ring 122 at the bottom of the inner wall of the cleaning cylinder 121, the second gear 213 revolves around the first gear 212 while also rotating on its own axis. The rotation of gear 12 simultaneously drives the bidirectional screw 221 connected to its center to rotate. The stirring blades 222 at the lower end of the bidirectional screw 221 rotate accordingly, forming a downward or upward longitudinal vortex flow field in the central region of the clean water inside the cleaning cylinder 121. Simultaneously, the revolution and rotation of the second gear 213 drive the shaft 231 and the helical blades 232 at the lower end of its outer wall to move. The shaft 231 revolves around the bidirectional screw 221, while the helical blades 232 rotate, forming multiple downward spiral vortices in the outer region of the clean water inside the cleaning cylinder 121. These spiral vortices not only rotate on their own but also revolve around the central vortex, thus constructing a complex planetary double-vortex coupled stirring flow field inside the cleaning cylinder 121. This flow field causes the water flow to generate multi-dimensional... The intense turbulence and shearing force, without any blind spots, can continuously wash the surface of fruits and vegetables, effectively breaking the bond between pesticide residues and the surface. While the driving mechanism 2 generates a strong flow field, the rotation of the bidirectional screw 221 also drives the first limiting mechanism 3 and the second limiting mechanism 4 to perform dynamic adjustment and coordinated cleaning. The lower threaded section of the bidirectional screw 221 is threadedly engaged with the first internal thread block 331, and the upper threaded section is threadedly engaged with the second internal thread block 431. Since the upper and lower threads of the bidirectional screw 221 rotate in opposite directions, when it rotates, the first internal thread block 331 and the second internal thread block 431 will move closer to or further away from each other. When the first internal thread block 331 rises, it is driven by the third connecting rod 323, the electrolytic electrode plate 322, and the second connecting rod 321.An outward thrust is generated on the first fixed arc plate 311. Since the first fixed arc plate 311 is limited on the shaft 231 by the first connecting rod 315 and the first shaft seat 316, this thrust causes several sets of first fixed arc plates 311 to expand outward against the elastic force of the first flexible rib 314, thereby increasing the diameter of the first telescopic component 31. Conversely, when the first internal thread block 331 descends, it drives the first fixed arc plate 311 to contract inward, reducing the diameter. Similarly, the lifting and lowering of the second internal thread block 431 is driven by the linkage of the fifth connecting rod 421, the sixth connecting rod 422, the seventh connecting rod 423 and the eighth connecting rod 424, which drives the second fixed arc plate 411 to expand or contract synchronously. This is achieved by controlling the drive motor. The forward and reverse rotation of component 211 precisely controls the diameter of the first telescopic component 31 and the second telescopic component 41, ensuring continuous contact between the fruits and vegetables and the ultrasonic vibrating plate 433 and the spiral cotton 434. This achieves flexible wrapping and controlled cleaning of the fruits and vegetables. This dynamic control prevents the fruits and vegetables from moving randomly in the strong flow field, avoids damage from collisions, and ensures that they remain in the core cleaning area. While the control mechanism adjusts the diameter, the first electrolysis component 32 and the second electrolysis component 42 begin to operate. The electrolysis electrode plate 322 and the arc-shaped electrolysis plate 425 are energized, and the anode and cathode plates mounted on their surfaces electrolyze the water, producing highly oxidizing active substances such as hypochlorous acid and hydroxyl radicals. Under the action of a planetary double-vortex coupled stirring flow field, these active substances are rapidly and evenly diffused to every corner of the enveloping cleaning area, making full contact with the surface of fruits and vegetables. Through oxidation reaction, they efficiently degrade pesticide residues such as organophosphates and pyrethroids. At the same time, the ultrasonic vibration component 43 starts to work. The ultrasonic vibration plate 433 on the outer wall of the mounting cylinder 432 at the bottom of the second internal thread block 431 generates high-frequency ultrasonic vibrations, which are transmitted outward through the spiral cotton 434. The cavitation effect of the ultrasonic waves in the water instantly generates a large number of microbubbles. When these bubbles burst, they release huge energy, generating local high temperature and high pressure, which can directly break the chemical bonds of pesticide molecules. More importantly, the cavitation effect and mechanical properties of the ultrasonic waves... The effect greatly enhances the mass transfer process of the active substances in the electrolyzed water, promoting the penetration of active substances into the microscopic depressions and crevices on the surface of fruits and vegetables. The spiral cotton 434 not only acts as a buffer layer to prevent fruits and vegetables from being damaged by direct collision with the ultrasonic vibrating plate 433, but its spiral structure can also guide the water flow of the central vortex, guiding the active substances and ultrasonic energy to act more effectively on the surface of fruits and vegetables. In addition, the pulse nozzle 313 on the inner wall of the first telescopic component 31 can be programmed to intermittently generate high-pressure pulse water flow through an internal micro pump, performing targeted pulse impact on the surface of fruits and vegetables, further peeling off the degraded or loosened pesticide residues, and quickly flushing the pollutants away from the surface of fruits and vegetables, allowing them to enter the circulation or be discharged with the water flow. During the cleaning process,The planetary double-vortex coupled stirring flow field generated by the drive mechanism 2, the electrolyzed water active substances generated by the first electrolysis component 32 and the second electrolysis component 42, the ultrasonic cavitation effect generated by the ultrasonic vibration component 43, and the pulse impact generated by the pulse nozzle 313—these four cleaning forces work synergistically in time and space. The strong flow field ensures the uniformity and absence of dead zones in the action range of electrolyzed water and ultrasound; ultrasound enhances the mass transfer and reaction efficiency of electrolyzed water; and pulse impact strengthens the physical peeling effect. This multi-physical field synergistic cleaning method achieves efficient, rapid, and uniform degradation of pesticide residues on the surface of fruits and vegetables and in microscopic crevices. After cleaning, the operator opens the drain valve 114, and the wastewater in the cleaning cylinder 121 first passes through the first sealing plate 131. The wastewater seeps down through the gaps between the sealing blocks 132, and is then collected by the inclined surface of the second sealing disc 133 and guided to the guide ring 134. The guide ring 134 directs the wastewater into the second drainage trough 124, which in turn drains the wastewater into the first drainage trough 115 of the drainage ring 113. Finally, the wastewater is discharged through the drain valve 114. The sealing design of the guide assembly 13 ensures that wastewater does not seep into the mechanical transmission components below when the shaft 231 of the drive mechanism 2 rotates, thus guaranteeing the reliability and durability of the system. Throughout the cleaning process, the observation port 142 on the cover plate 141 allows operators to monitor the internal cleaning status at any time. Through the precise cooperation and coordinated work of the above components, this system achieves efficient degradation and cleaning of pesticide residues on fruits and vegetables, ultimately producing clean and safe fruits and vegetables.
