[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] like Figures 1 to 3 As shown, in a preferred embodiment, the present invention provides a system for the resource recycling of substandard dairy products, comprising: a sorting platform 1 for sorting qualified and substandard dairy products; a packaging breaking device 2, the inlet of which is connected to the outlet of the sorting platform 1, the packaging breaking device 2 being used to puncture the packaging boxes of substandard dairy products; and a sterilization device 3 disposed below the outlet of the packaging breaking device 2, the sterilization device 3 comprising a cleaning component, a disinfection component, and a conveyor belt 3. 02. The cleaning component and the disinfection component are both located above the conveyor belt 302. A screen frame 301 is provided on the conveyor belt 302. The screen frame 301 is used to separate the packaging box from the milk liquid and the mixed liquid. A pressing device 4 is used to punch holes in the packaging box. The inlet of the pressing device 4 is connected to the outlet of the sterilization device 3. The pressing device 4 is used to separate the packaging box from the milk liquid. A separation device 5 is used to separate the paper, aluminum foil and plastic film.

[0039] Furthermore, the sterilization device 3 also includes a storage tank 309. A conveyor belt 302 is disposed on opposite sides of the storage tank 309 and is driven by a drive motor 314 disposed on the outside of the storage tank 309. A vibration motor 303 is disposed on one side of the storage tank 309, and the vibration motor 303 drives the sieve frame 301 to vibrate. The storage tank 309 stores liquid and also supports the conveyor belt 302. To allow the milk liquid and the mixture obtained after rinsing to be collected and used, a storage port may be provided at the bottom of the storage tank 309. The vibration motor 303 drives the sieve frame 301 to vibrate via a telescopic rod. The drive motor 314 drives the conveyor belt 302 to rotate via a transmission wheel and a tension wheel. The tension wheel prevents the conveyor belt 302 from loosening due to prolonged use during rotation.

[0040] Furthermore, each end of the sieve frame 301 is provided with a frame rim 313, which is placed on the conveyor belt 302. The frame rim 313 is integrally formed with the sieve frame 301 or detachably connected. The two frame rims 313 are respectively placed on the upper part of the conveyor belt 302 on both sides of the sieve frame 301, and the conveyor belt 302 drives the sieve frame 301 to move through the frame rims 313. Based on this design, the bottom of the sieve frame 301 is provided with holes of uniform size. To ensure the smooth operation of the sieve frame 301, the top of the frame rim 313 cannot be higher than the top of the liquid storage tank 309.

[0041] Furthermore, a partition 312 is provided within the storage tank 309, dividing it into a first storage tank 310 and a second storage tank 311. The first storage tank 310 is used to store liquid milk, and the second storage tank 311 is used to store a mixed liquid. Based on this design, different types and concentrations of liquids are stored separately. Pure liquid milk can be recovered and used as feed or for other purposes, enhancing resource reuse. The low-concentration mixed liquid generated after rinsing the packaging can be filtered, sterilized, and used as industrial water.

[0042] In one embodiment, the cleaning assembly includes a main water supply pipe 304, on which a plurality of spray pipes 305 are disposed. One end of each spray pipe 305 is connected to the main water supply pipe 304, and a plurality of nozzles 306 are disposed on each spray pipe 305. Further, the main water supply pipe 304 is connected to a water source, and the plurality of spray pipes 305 are vertically installed to and fixedly connected to the main water supply pipe 304. The spray pipes 305 are internally connected to the main water supply pipe 304, and the nozzles 306 may have a conical cross-section to increase the water pressure. These technical features increase both the spraying area and the spraying pressure, resulting in a superior cleaning effect on the packaging box. Furthermore, the main water supply pipe 304 and the spray pipe 305 are positioned above the second liquid storage tank 311. Two identical supports are fixedly installed on the upper ends of opposite side walls of the second liquid storage tank 311. These supports support the main water supply pipe 304, and each support has a semi-circular groove with the same diameter as the main water supply pipe 304 at its upper end, into which the main water supply pipe 304 is embedded. A rectangular support plate perpendicular to the side walls of the second liquid storage tank 311 is also provided on the upper ends of opposite side walls of the second liquid storage tank 311. Both ends of the support plate are fixedly connected to the upper ends of opposite side walls of the second liquid storage tank 311. The upper end of the support plate has several equally spaced semi-circular grooves with the same diameter as the spray pipe 305, into which one end of the spray pipe 305 is embedded.

[0043] In another embodiment, the disinfection assembly includes a disinfection chamber 308, within which a plurality of ultraviolet lamps 307 are fixedly installed. The disinfection chamber 308 prevents workers from being exposed to ultraviolet radiation during operation. The bottom of the disinfection chamber 308 is hollow; when a packaging box moves beneath it, the ultraviolet lamps 307 disinfect the box. Specifically, the ultraviolet lamps 307 are embedded between the two side walls of the disinfection chamber 308, and the plurality of ultraviolet lamps 307 are arranged at equal intervals. The ultraviolet lamps 307 provide a simpler and more effective disinfection process for the packaging box.

[0044] Furthermore, the disinfection chamber 308 is also equipped with a power supply 316, which supplies power to the ultraviolet lamp 307. Specifically, the power supply 316 is located on the outside of the disinfection chamber 308. One end of the ultraviolet lamp 307 is provided with a support base, and the ultraviolet lamp 307 is mounted in the support base. A circular groove is provided on an inner side wall of the disinfection chamber 308, and the support base is embedded in the circular groove. The other end of the ultraviolet lamp 307 is provided with a plug, and the power supply 316 supplies power to the ultraviolet lamp 307 through the plug.

[0045] Furthermore, a controller 315 is installed on the liquid storage tank 309. The controller 315 is signal-connected to the drive motor 314, the vibration motor 303, the cleaning assembly, and the disinfection assembly. The controller 315 can control the start and stop of the drive motor 314 and the vibration motor 303. When the drive motor 314 and the vibration motor 303 do not need to work, they can stop working, thereby saving electricity and reducing equipment wear and tear. At the same time, it can also control the cleaning assembly and the disinfection assembly, avoiding water waste and prolonged ultraviolet radiation to workers when not in use.

[0046] The present invention also provides a method for sterilization using the above system, comprising the following steps:

[0047] S1: Unqualified dairy products are sorted out through the sorting platform;

[0048] S2: Place the substandard dairy product packaging box into the packaging breaking device for puncturing and squeezing;

[0049] S3: The punctured and squeezed packaging boxes are cleaned and disinfected by a sterilization device;

[0050] S4: Dry, pack, and collect the cleaned and disinfected packaging boxes;

[0051] S5: Transport the packaging box to the pressing device for punching and pressing; punching;

[0052] S6: The perforated packaging box is fed into the separation tank through the feed inlet for separation of paper, aluminum foil and plastic film;

[0053] S7: Collect the separated pulp, aluminum foil, and plastic film.

[0054] Specifically, in S3, the microcontroller installed in the controller detects and controls the entire cleaning, disinfection, and vibration process. The specific steps are as follows:

[0055] S31: Determine whether the sieve frame contains punctured or squeezed packaging boxes;

[0056] S311 If not, the vibration motor remains in the off state;

[0057] If S312 is true, then turn on the vibration motor, vibrate for 5-8 minutes, then turn off the vibration motor, turn on the drive motor, and determine whether there is a packaging box under the cleaning component;

[0058] S3121 If not, the drive motor remains in the on state;

[0059] If S3122 is true, then turn off the drive motor, turn on the vibration motor and simultaneously turn on the cleaning component for 15-20 minutes, then turn off the cleaning component and the vibration motor; turn on the drive motor again and determine whether there is a cleaned packaging box under the disinfection component;

[0060] S31221 If not, the drive motor remains in the on state;

[0061] If S31222 is true, then turn off the drive motor, turn on the vibration motor and simultaneously turn on the sterilization component. After 10-15 minutes, turn off the sterilization component and the vibration motor, turn on the drive motor, and let the sterilized packaging box enter the pressing device to start punching.

[0062] In the above steps, the microcontroller in the controller monitors and controls the entire cleaning, disinfection, and vibration process in real time. The required working time and the method for recognizing the packaging box are set in advance. Before starting work, the drive motor, the vibration motor, the cleaning component, and the disinfection component are all in a stopped state. When the packaging box enters the sieve frame, the microcontroller unit in the controller detects the packaging box and starts the vibration motor, with a vibration time of 5-8 minutes. During operation, the vibration motor drives the sieve frame to vibrate via a telescopic rod, causing the packaging box to tumble within the sieve frame, allowing the milk liquid in the packaging box to flow into the first storage tank through the holes at the bottom of the sieve frame. After the set vibration time ends, the vibration motor stops working, and the drive motor starts working, driving the sieve frame to move. When the sieve frame moves to below the cleaning component, the controller detects the packaging box. At this time, the drive motor stops working, and the vibration motor and the cleaning component start working, with a vibration and cleaning time of 15-20 minutes. During the cleaning process, the vibration of the sieve frame completely washes away any residual liquid in the packaging box. After the set cleaning time is completed, the milk liquid in the packaging box has been completely washed away. The vibration motor and the cleaning assembly stop working, and the drive motor starts working. When the sieve frame moves under the sterilization assembly, the controller detects the packaging box, the drive motor stops working, and the vibration motor and the sterilization assembly start working. The vibration and sterilization time is 10-15 minutes. During the sterilization process, the vibration of the sieve frame can effectively sterilize the packaging box thoroughly. After the set sterilization time is completed, the vibration motor and the sterilization assembly stop working, and the drive motor starts working and drives the sieve frame to continue running into the pressing device.

[0063] The embodiments described above merely illustrate the device layout of this application. The descriptions are quite specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make several adjustments and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be based on the appended claims.
