Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of wine bottle cleaning, and in particular to a method and system for cleaning wine bottles using micro-nano bubbles. Background Art
[0002] As a classic glass container in the food packaging field, beer bottles, with their excellent sealing performance and chemical stability, are ideal containers for carbonated beverages such as beer. Their material properties determine their natural recycling genes. Not only can they isolate oxygen and odors, ensuring the long-lasting and pure flavor of the beer, but they can also be refilled 20 to 50 times through standardized production, reducing the cost per use by more than 60% compared to disposable containers. In the beer bottle recycling process, inner wall cleaning is a key link. Although the existing technology has achieved basic cleaning, in the traditional high-pressure spraying process, the linear motion of the nozzle is difficult to cover the bottleneck thread groove and the arc area of the bottle bottom, resulting in residual wine stains, protein film and other stubborn stains. The total colony count in the unwashed area may exceed the standard by 5-10 times, directly affecting the safety of the beverage after refilling. Secondly, an external liquid conveying mechanism needs to be set in the spray cleaning operation of the inner wall of the beer bottle. The external liquid conveying mechanism is usually equipped with an independent motor, pump body and control system. The overall power of the equipment is greatly improved, and there are obvious disadvantages such as high energy consumption, complex structure and poor reliability. In response to the above problems, the inventors proposed a method and system for washing wine bottles using micro-nano bubbles to solve the above problems. Summary of the Invention
[0003] In order to solve the problem of fully cleaning the inside of beer bottles and reducing the energy consumption of the device, the purpose of the present invention is to provide a method and system for washing beer bottles using micro-nano bubbles.
[0004] To solve the above technical problems, the present invention adopts the following technical solution: a method for washing wine bottles using micro-nano bubbles, comprising the following steps: S1. Beer bottles are automatically transported by a conveyor system to the washing line, where labels are removed through high-pressure water flow and mechanical stripping. They then enter the pre-spray cleaning section, where a high-pressure water array nozzle is used to flush away large dirt and dust on the bottle's outer surface. Simultaneously, the bottles pass through a vibrating screening unit, where high-frequency vibrations remove any remaining debris, sand, and other foreign matter. S2. After pretreatment, the beer bottles enter a multi-stage soaking tank. A micro-nano bubble generator is added to the water to remove dirt inside and outside the bottles through the physical action of bubble bursting. The water temperature is controlled at 40-50°C. S3. The beer bottles after soaking and cleaning are transported to the high-pressure spray cleaning station. The high-pressure spray cleaning is divided into two parts: external spraying and internal spraying. During the spraying process, micro-nano bubbles are introduced into the spray water to assist the spraying and improve the cleaning efficiency. S4. During the spraying process, ozone is mixed into the micro-nano bubbles for sterilization and disinfection to remove residual odors and bacteria; S5. The nano-filtration membrane and the precipitation filtration system are used to recycle the cleaning water, and the filtered water is returned to the soaking tank and the spraying system; S6. After cleaning, an industrial camera is used to detect the cleanliness, label residue and appearance defects of the bottles, and at the same time check whether there are cracks or damages on the bottle body. The unqualified bottles are automatically removed by the sorting device to ensure the cleaning quality; S7. Finally, the high-pressure air knife and hot air cooperate with each other to remove the moisture inside and outside the bottle for drying. The dried bottles are conveyed to the next production process through the conveyor belt.

The dirt inside and outside the bottle is peeled off by the physical action generated by the bursting of the bubbles, and the water temperature is controlled at 40-50 °C; S3. The soaked and cleaned beer bottles are transported to the high-pressure spray cleaning station. The high-pressure spray cleaning is divided into two parts: external spray and internal spray. During the spraying process, micro-nano bubbles are introduced into the spray water, and the cleaning efficiency is improved by the assistance of micro-nano bubbles for spraying; S4. During the spraying process, ozone is mixed into the micro-nano bubbles for sterilization and disinfection to remove the remaining odor and bacteria; S5. The cleaning water is recycled by using a nano filtration membrane and a precipitation filtration system, and the filtered water is returned to the soaking tank and the spray system; After cleaning, the cleanliness, label residue, and appearance defects of the bottles are detected by an industrial camera. Meanwhile, whether there are cracks or damages on the bottle body is checked, and the unqualified bottles are automatically removed by a sorting device to ensure the cleaning quality; Finally, the moisture inside and outside the bottles is removed by the cooperation of a high-pressure air knife and hot air for drying. The dried bottles are conveyed to the next production process through a conveyor belt.
[0012] A system used for a method of washing wine bottles using micro-nano bubbles includes a machine base 1 for supporting the equipment and a bottle washing and palletizing machine 2 for palletizing and regularizing the wine bottles. The bottle washing and palletizing machine 2 is located on the opposite side of the machine base 1. An automatic cleaning drive mechanism 3 and a spray water automatic conveying mechanism 4 are integrated on the top of the machine base 1. The automatic cleaning drive mechanism 3 includes a nozzle rotation drive assembly 31 and a nozzle pushing-in assembly 32. The spray water automatic conveying mechanism 4 includes a spray water conveying assembly 41 and a rotary pipeline liquid infusion assembly 42. A micro-nano bubble generator 5 is provided below the machine base 1 for introducing micro-nano bubbles into the spray water; The nozzle rotation drive assembly 31 includes a drive shaft 311 and a worm 312. The drive shaft 311 is rotatably installed at the top of the machine base 1 through a shaft seat. The worm 312 is fixedly sleeved in the middle of the outer wall of the drive shaft 311. One end of the outer wall of the drive shaft 311 close to the bottle washing and palletizing machine 2 is slidably connected with a sliding shaft 313 through a spline; The nozzle pushing-in assembly 32 includes a push frame 321 and a guide ring 322. The push frame 321 is slidably installed on one side of the top of the machine base 1 close to the drive shaft 311. The guide ring 322 is fixedly installed at one end of the outer wall of the sliding shaft 313 close to the push frame 321, and the guide ring 322 is rotatably installed on the push frame 321. A sliding bracket 323 is slidably installed on one side of the top of the machine base 1 close to the bottle washing and palletizing machine 2 through a slide rail; The spray water conveying assembly 41 includes a base 411 and a cavity 412. The base 411 is fixedly installed on one side of the top of the machine base 1 close to the worm 312. The cavity 412 is fixedly installed on the top of the base 411. Two symmetrically distributed transmission shafts 413 are horizontally rotatably arranged inside the cavity 412. Three-lobe cam rotors 414 are fixedly sleeved on the outer walls of the two transmission shafts 413 for cleaning agent conveying; The rotary pipeline liquid infusion assembly 42 includes three equally spaced liquid guiding steel pipes 421 and a liquid inlet frame 422. The three liquid inlet frames 422 are all fixedly installed on the sliding bracket 323. The three liquid guiding steel pipes 421 are respectively rotatably installed in the corresponding liquid inlet frames 422. A high-pressure nozzle 423 is fixedly installed at the end of the liquid guiding steel pipe 421 through a nylon nut and a sealing ring by threading.
[0013] By adopting the above technical solution, while the automatic cleaning drive mechanism 3 drives the high-pressure nozzle 423 to rotate, it also drives the high-pressure nozzle 423 to reciprocate along the axial direction of the bottle, achieving full-depth cleaning coverage from the bottle mouth to the bottle bottom. At the same time, the spray water automatic conveying mechanism 4 continuously conveys spray water to the high-pressure nozzle 423.
[0014] A driven shaft 314 is rotatably provided on the top end of the machine base 1 near one side of the worm 312. A worm gear 315 is fixedly installed on the outer wall of the driven shaft 314, and the worm gear 315 is meshed and connected with the worm 312.
[0015] By adopting the above technical solution, during the rotation of the drive shaft 311, the driven shaft 314 is driven to rotate through the worm 312 and the worm gear 315.
[0016] A rotating rod 324 is fixedly installed at the top end of the driven shaft 314. One end of the rotating rod 324 is rotatably hinged with a push rod 325, and the other end of the push rod 325 is rotatably hinged with the top end of the push frame 321. A guide rod 326 is fixedly installed on one side of the top end of the machine base 1, and the push frame 321 is slidably connected with the guide rod 326 through a spline.
[0017] By adopting the above technical solution, the degree of freedom of the push frame 321 is restricted through the cooperation of the spline and the guide rod 326, ensuring that it slides stably along the axial direction of the guide rod 326 strictly.
[0018] Two transmission shafts 413 are rotatably installed in the cavity 412 through labyrinth seal bearings. Rotating gears 415 are fixedly sleeved on the outer walls of the two transmission shafts 413, and the two rotating gears 415 are meshed with each other. A transmission gear 416 is fixedly sleeved on the outer wall of the drive shaft 311, and the transmission gear 416 is meshed with the adjacent rotating gear 415.
[0019] By adopting the above technical solution, during the rotation of the drive shaft 311, the two transmission gears 416 are driven to form a mirror-symmetrical reverse synchronous movement through the transmission gear 416 and the rotating gears 415.
[0020] A limiting frame 425 is fixedly installed in the middle of the top end of the sliding bracket 323. A flow dividing tee 426 is installed at the top end of the limiting frame 425. The limiting frame 425 at the top end of the sliding bracket 323 forms a rigid support for the flow dividing tee 426. The three water outlet ends of the flow dividing tee 426 are respectively connected in communication with the water inlet ends of the corresponding liquid inlet frames 422. A hose 427 is connected in communication with the water inlet end of the flow dividing tee 426.
[0021] By adopting the above technical solution, the spray water input by the hose 427 is synchronously conveyed to the corresponding liquid inlet frames 422 through the three water outlet ends of the flow dividing tee 426 according to the equal-pressure flow dividing principle.
[0022] The water inlet end of the cavity 412 is connected throughly with an inlet pipe 417, and the water inlet end of the inlet pipe 417 is connected throughly with the water outlet end of the micro-nano bubble generator 5. The water outlet end of the cavity 412 is connected throughly with an outlet pipe 418, and the other end of the flexible hose 427 is connected throughly with the outlet pipe 418.
[0023] By adopting the above technical solution, the through connection of the cavity 412 with the inlet pipe 417, the outlet pipe 418 and the micro-nano bubble generator 5 constructs a complete liquid-gas transmission system, and sprays water containing micro-nano bubbles from the micro-nano bubble generator 5 through the inlet pipe 417, the cavity 412, the outlet pipe 418 and is transported into the flexible hose 427.
[0024] On one side of the top end of the pushing frame 321, two symmetrically distributed guide bolts are fixedly arranged, and the guide ring 322 is located between the two guide bolts and is rotatably connected with the guide bolts.
[0025] By adopting the above technical solution, the guide ring 322 can rotate flexibly between the two symmetrically distributed guide bolts. At the same time, the pushing frame 321 drives the guide ring 322 to translate along the preset direction through the guide bolts, realizing the coordinated control of the rotational degree of freedom and the linear motion.
[0026] The liquid guiding steel pipe 421 is a hollow tapered rod body, which smoothly narrows and extends from the thick end to the thin end. The thin end of the liquid guiding steel pipe 421 is connected throughly with the high-pressure nozzle 423. Sealing members 424 are sleeved on the protruding parts of the outer wall of the thick end of the liquid guiding steel pipe 421. The thick solid end of the middle liquid guiding steel pipe 421 and the sliding shaft 313 are fixedly connected through a coupling. The three liquid guiding steel pipes 421 are connected through a synchronous pulley transmission group.
[0027] By adopting the above technical solution, the liquid guiding steel pipe 421 is designed as a hollow tapered shape, and the liquid flow rate increases as the pipe diameter decreases. Cooperating with the high-pressure nozzle 423 can form a high-speed jet to improve the cleaning efficiency.
[0028] On one side of the top end of the machine base 1 close to the axis of the driving shaft 311, a motor 316 is fixedly installed, and the driving end of the motor 316 is fixedly connected with the axis of the driving shaft 311.
[0029] By adopting the above technical solution, the motor 316 continuously provides a stable power source for the driving shaft 311.
[0030] Working principle: In the actual production process, as Figure 2 shown, after the bottle washing and palletizing machine 2 palletizes and sorts the beer bottles, it drives the palletized beer bottles to rotate to the horizontal. At this time, the bottle mouth of the beer bottle is facing the high-pressure nozzle 423. Subsequently, the micro-nano bubble generator 5 is controlled to be turned on, introducing micro-nano bubbles into the spray water and continuously introducing ozone into the spray water, so that the ozone is mixed into the micro-nano bubble spray water; When flushing the inner wall of the beer bottle, as Figure 2As shown in the figure, the motor 316 is started, driving the drive shaft 311 to rotate counterclockwise. The drive shaft 311 synchronously drives the transmission gear 416 to rotate. From Figure 8 (opposite to the Figure 2 perspective), the transmission gear 416 rotates clockwise. The transmission gear 416 drives the adjacent meshing rotating gear 415 on the left to rotate counterclockwise, and the left rotating gear 415 drives the right rotating gear 415 to rotate clockwise. The two rotating gears 415 respectively drive the three-lobe cam rotor 414 to rotate synchronously through the corresponding transmission shafts 413. As the three-lobe cam rotor 414 rotates in the cavity 412, the mixed spray water in the micro-nano bubble generator 5 enters the cavity 412 through the inlet pipe 417. Under the coordinated action of the two three-lobe cam rotors 414, the spray water flows out from the outlet pipe 418 and is transported to the split tee 426 through the hose 427. According to the principle of equal-pressure splitting, the spray water is synchronously transported to the corresponding liquid inlet frame 422, as Figure 9 , Figure 10 shown. The spray water in the liquid inlet frame 422 flows into the hollow area inside the liquid guide steel pipe 421 through the liquid inlet holes on the liquid guide steel pipe 421. Since the hollow pipe wall of the liquid guide steel pipe 421 is in a tapered contraction structure, the flow rate of the spray water increases when passing through, and then enters the high-pressure nozzle 423 and sprays out. The high-pressure nozzle 423 is provided with two nozzles, the upper nozzle is inclined at 45° to the axis of the liquid guide steel pipe 421, and the lower nozzle is inclined at 65° to the axis of the liquid guide steel pipe 421. Through the angle setting, the water flow sprayed by the upper nozzle can obliquely wash the upper area of the inner wall of the beer bottle at a suitable angle, effectively covering the upper part of the bottle wall and using the impact force of the water flow to peel off stains. The water flow sprayed by the lower nozzle is at a more inclined angle and deeply acts on the lower area of the inner wall of the beer bottle, enhancing the cleaning strength of the bottom and the lower bottle wall, realizing a three-dimensional cleaning effect of upper flushing and lower brushing; As Figure 2 , [[ID=]13] Figure 3 , Figure 6 shown, during the rotation of the drive shaft 311, the sliding shaft 313 is synchronously rotated through the spline. The sliding shaft 313 drives the middle liquid guide steel pipe 421 to rotate through the coupling. The middle liquid guide steel pipe 421 drives the liquid guide steel pipes 421 on both sides to rotate at the same speed and synchronously through the synchronous pulley transmission group, and then drives the three high-pressure nozzles 423 to rotate synchronously, forming a circumferential 360° dead-angle-free cleaning coverage; Meanwhile, the worm 312 on the drive shaft 311 meshes with the worm gear 315 on the driven shaft 314 to transmit power to the driven shaft 314. The rotating rod 324 at the top of the driven shaft 314 makes a circular motion along with the driven shaft 314, and converts the circular motion into a linear reciprocating motion of the push frame 321 through the push rod 325. Under the spline guiding action of the guide rod 326, the push frame 321 makes a stable linear motion along the axial direction, and is rotationally connected to the guide ring 322 through a guide bolt, driving the sliding shaft 313 and the liquid guide steel pipe 421 as a whole to reciprocate and translate along the slide rail. The rotational motion of the high-pressure nozzle 423 and the axial reciprocating motion are superimposed on each other to form a spiral cleaning trajectory, ensuring that during the whole process of the nozzle entering from the bottle mouth to the bottle bottom and then exiting, the spraying coverage area of the cleaning liquid completely covers the inner surface of the bottle, realizing efficient cleaning with full depth and no blind spots.
