Description

Technical Field

[0001] The invention belongs to the field of bottled water bucket cleaning systems and relates to a bottled water bucket inner wall cleaning machine and a cleaning method. Background Art

[0002] Bottled water and water dispensers have entered thousands of households, bringing convenience to people. Choosing bottled water is of great significance to improving people's health. Choosing bottled water in its natural state and containing an appropriate amount of beneficial mineral components is of great significance to human health. Pure water prepared by reverse osmosis, electrodialysis, distillation, resin softening, etc. At present, the inner wall of the barrel of bottled water is cleaned by inverting it on the cleaning mechanism, and using a cleaning nozzle with the nozzle facing upward to clean the inner wall of the barrel. The barrel of bottled water is inverted on the cleaning mechanism. During the cleaning process, due to the influence of gravity, the cleaning solution transitions from the bottom of the barrel to the barrel wall and barrel neck. Some impurities are easily accumulated at the mouth of the barrel, resulting in the possibility of inadequate cleaning.

[0003] The other technologies use contact cleaning to clean the impurities at the mouth of the bucket to solve the above problems. At present, the inner wall of the barrel of bottled water is cleaned by using a bucket brush. The motor drives the bucket brush with a telescopic rod to clean the entire inner wall of the bucket. However, since this technology also requires the bucket brush to be cleaned and disinfected, the bucket brush contains impurities or other substances, which causes secondary pollution to the inner wall of the bucket. It is inconvenient to operate, time-consuming and labor-intensive, has low work efficiency, is not thoroughly cleaned, and the brush is easily damaged. Replacing the brush brings a lot of inconvenience to people. For drinking water companies, solving the problem of rapid cleaning of drinking water buckets is urgent.

[0004] At present, the cleaning nozzles for cleaning buckets mainly use nozzles or combinations of DC cone spray, inserted dispersed spray, and mist spray. Various nozzles are affected by the spray angle when in use, and there are some dead angles and uneven force in the spraying process. The wide-angle spray nozzle has less force in the middle area of ​​the coverage surface, and the narrow-angle spray nozzle has limited coverage. There are multiple spray dead angles in the porous narrow-angle nozzle. The mist nozzle has a better effect on disinfection, but the contact surface impact force is insufficient when used as a flushing bucket.

[0005] Cleaning the inner wall of the barrel of bottled water is an important part of the production of bottled water. Therefore, there is an urgent need for a cleaning method that can clean thoroughly without causing secondary contamination of the inner wall of the barrel, and a cleaning system that can spray the entire empty barrel in all directions.

Four lifting cylinders 23 are arranged at the bottom of the movable conveyor 21, and the extension and contraction of the lifting rods of the lifting cylinders 23 are controlled by the program control box 5, so that the movable conveyor 21 moves in the vertical direction. The bottom of the movable conveyor 21 is provided with a liquid tank 24 that matches the number of cleaning chambers, which can receive the liquid flowing out of the spray device 4 and the water bucket 7.

[0041] The bucket fixing device 3 is connected to the machine body 1 by being fixedly connected to the rotating disk 15; the bucket fixing device 3 is composed of two clamping plates 31 and several clamping mechanisms 34, the clamping plates 31 are hollow structures, the head and tail ends of the clamping plates 31 are respectively fixedly connected to two rotating members 32, and the rotating members 32 are fixedly connected to the rotating disk 15; on the opposite plate surfaces of the two clamping plates 31, several barrel mouth grooves are respectively arranged, and the positions of the barrel mouth grooves on the two clamping plates correspond to each other, so that the two barrel mouth grooves corresponding to each other form a clamping hole 33 adapted to the barrel mouth of the bucket, and the number of the clamping holes 33 is consistent with the number of the rotating nozzles 46 ; A clamping mechanism 34 is provided in the clamping plates 31 on both sides of the clamping hole 33, and the clamping mechanism 34 is located between the two clamping plates 31. The clamping mechanism 3 includes an electromagnetic switch controller 341, an electromagnetic switch 342, and a clamping arc 343. One end of the electromagnetic switch 342 is connected to the electromagnetic switch controller 341 through a connecting rod, and the other end is connected to the clamping arc 343 through a piston rod. The clamping arc 343 is connected to the outer shell of the electromagnetic switch controller 341 through a spring. Except for the clamping arc 343, the clamping mechanisms 34 are all placed in a hollow shell 35 to prevent liquid from flowing in, and the clamping arcs 343 of the clamping mechanisms 34 are all located at the edge of the clamping hole 33. When the clamping mechanism 34 is energized, the electromagnetic switch 342 is energized through the action of the electromagnetic switch controller 341, and shrinks to the side away from the clamping hole 33, thereby causing the clamping arc 343 to shrink. When the power is off, the electromagnetic switch 342 loses power through the action of the electromagnetic switch controller 341, and extends to the side of the clamping hole 33, thereby causing the clamping arc 343 to extend, and finally clamps the bucket, thereby better fixing the bucket.

[0042] The spray water pipe 41 in the spray device 4 passes through the rotating disk 15 and is fixedly connected to the rotating disk 15, so as to realize the fixed connection between the spray device 4 and the bucket fixing device 3 and the machine body 1.

The spray device 4 is composed of a spray water pipe 41, a water delivery pipe 42, a liquid tank 43, a water delivery pump 44, a connecting pipe 45 and a rotating nozzle 46. The head end or the end of the spray water pipe 41 is connected to the rotating shaft 61 of the rotating motor 6. Under the drive of the rotating motor 6, the rotating shaft 61 drives the spray pipe 41 to rotate. Since the spray water pipe 41 is connected to the rotating disk 15, the bucket fixing device 3 is driven to rotate. The liquid tank 43 is arranged at the bottom of each cleaning chamber 12. One end of the water delivery pipe 42 is connected to the water delivery pump 44 to deliver liquid, and the other end is connected to the wall of the connecting pipe 45 and fixedly connected. The spray water pipe 41 passes from the bottom surface of the connecting pipe 45 to the top surface.

The spray water pipe 41 nested in the connecting pipe 45 is provided with a water injection hole 411, which can transport the water in the water delivery pipe 42 to the spray water pipe 41, and then the rotating nozzle 46 sprays it out.

[0043] The spray water pipe 41 is provided with three rotating nozzles 46, which are opened in three levels on the side and top of the cylindrical body of the rotating nozzle 46, forming a spray port 461, which sprays in a fan-shaped line. The three spray ports 461 are respectively used to spray the bottom, side and shoulder of the barrel. When spraying, they automatically rotate under the action of pressure to spray the entire empty barrel in all directions, which not only compensates for the uneven force but also ensures full coverage of the empty barrel cleaning contact surface. A partition 412 is set between the spray water pipes 41 between different cleaning chambers to prevent different liquids from entering the spray water pipes 41 in the same cleaning chamber.

[0047] 2. Alkaline solution spraying: It includes six alkaline solution spraying processes. The solution used in each alkaline solution cleaning process is sodium hydroxide solution with a concentration of 1500ppm, a spraying time of 65 seconds, a solution temperature of 65℃, and a spraying pressure of 0.2MPa. The barrel mouth is upward, the nozzle enters the barrel mouth, and the bucket sprays at the position where the barrel mouth is upward and downward, which is an alkaline solution spraying; after the spraying is completed, it is dripped dry and enters the next step.

[0048] 3. B round pure water spraying: It includes a B round clean water spraying process, the spraying time is 55 seconds, the solution temperature is 55℃, and the spraying pressure is 0.4MPa.

The barrel mouth is upward, the nozzle enters the barrel mouth, and the water bucket sprays at the position where the barrel mouth is upward and downward, which is one acid solution spraying; after the spraying is completed, it is dripped dry and set aside.

[0051] The above cleaning process includes 22 steps in total.

[0052] When in use, the present invention is first powered on, and the bucket 7 to be cleaned on the inner wall is placed on the fixed conveyor 21 with the mouth of the bucket facing upward. The program control box 5 controls the roller conveyor 2 to transport the bucket 7 to the cleaning bin. When the mouth of the first batch of buckets 7 is completely aligned with the clamping hole 32, the program control box 5 controls the lifting cylinder 23 lifting rod to output a lifting force upward to synchronously drive the movable conveyor 21 to move upward and fix the bucket on the clamping hole 32. Then, through the action of the solenoid valve controller 341, the solenoid valve 342 loses power, and the clamping arc 343 extends to one side of the clamping hole 33 along the piston rod under the action of the spring, so that the clamping arc 343 continues to extend under the action of the spring, and finally clamps the bucket, so as to better fix the bucket.

After the first cleaning is completed, the program control box 5 controls the rotating motor 6. Under the drive of the rotating motor 6, the rotating shaft 61 drives the spray pipe 41 to rotate. Since the spray water pipe 41 is connected to the rotating disk 15, the rotation of the bucket fixing device 3 is driven, and finally the bucket 7 is rotated 180°, with the barrel mouth facing downward. Repeat the spray cleaning again. After the end, the bucket 7 is rotated 180° according to the original rotation path, with the barrel mouth facing upward. In the present embodiment, the positions of the barrel mouth upward and the barrel mouth downward are sprayed respectively, and the rotation shaft in the embodiment 1 drives the spray water pipe and the bucket fixing device to rotate, so as to avoid the problem that the cleaning solution is transferred from the bottom of the bucket to the barrel wall and the barrel neck due to the action of gravity, and some impurities are easily accumulated at the barrel mouth, causing the problem of inadequate cleaning. During the cleaning process, the bucket rotates 180 degrees, and the impurities accumulated at the barrel mouth may be removed under the driving of the rotation force. At this time, through the action of the solenoid valve controller 341, the solenoid valve 342 is energized, and the piston rod drives the clamping arc 343 to magnetically adsorb with the connecting rod, so that the clamping arc 343 retracts to the side away from the clamping hole 33, thereby causing the clamping arc 343 to shrink, so that the bucket is put down, and the program control box 5 controls the lifting cylinder 23 to move the lifting rod downward, so as to synchronously drive the movable conveying device 21 to move downward, and the program control box 5 controls the movable conveying device 21 to convey the bucket 7 to the next cleaning bin for cleaning, until the cleaning is completed, and the bucket 7 is conveyed to the outside of the machine body 1. By adding liquids required for spraying into different liquid boxes 43, the bucket can be effectively cleaned.
