Abstract
Description
Technical Field
[0001] This application relates to the field of spray sterilization technology, and in particular to a tunnel spray sterilization device. Background Technology
[0002] In the field of hygiene control in food processing and packaging, spray sterilization devices play multiple roles, including killing harmful microorganisms, ensuring food safety, and extending product shelf life. Therefore, spray sterilization devices occupy a crucial position in food production lines.
[0003] A related spray sterilization device includes a sterilization tank with a placement chamber for holding bottles to be sterilized. A spray head is mounted on top of the sterilization tank, and the tip of the spray head is connected to a steam chamber. In actual operation, the bottles to be sterilized are placed into the sterilization tank, and the spray head is activated, causing the spray head to spray steam from the steam chamber into the placement chamber, thereby sterilizing the bottles.
[0004] However, in practical applications, the bottles inside the sterilization tank come into contact with each other, and the spray head cannot spray every part of every bottle. This phenomenon results in some bottles not being fully sprayed during the sterilization process, and uneven steam coverage, which leads to inadequate sterilization. This not only affects the hygiene and quality of food, but may also cause food safety hazards. Utility Model Content
[0005] To improve the quality of bottle sterilization, this application provides a tunnel spray sterilization device.
[0006] This application provides a tunnel spray sterilization device, which adopts the following technical solution: A tunnel spray sterilization device, comprising: A sterilization box, wherein the sterilization box is set on the ground and a sterilization chamber is horizontally arranged inside the sterilization box; Mounting bracket, which is fixedly installed inside the sterilization chamber; A spraying component is disposed in the sterilization chamber and is slidably connected to the sterilization box to achieve sterilization of the bottle body; A movable component, disposed within the sterilization chamber, comprises: The mounting frame has multiple placement plates spaced apart along its length. Each placement plate is slidably disposed inside the sterilization box. The lower end of each placement plate abuts against the upper end of the mounting frame. The placement plate is parallel to the width direction of the mounting frame. The mounting component is fixedly disposed within the mounting frame; A toggle element, which is slidably disposed within the mounting component via the moving assembly, is used to control the movement of the placement plate.
[0007] By adopting the above technical solution, the sterilization box and sterilization chamber are designed to accommodate the installation of the mounting rack and spray components. The mounting rack is used to install the moving components, and the placement plate is used to place and move the bottles. When the actuating component rotates within the mounting components, it pushes the placement plate to slide on the mounting rack, thereby moving the bottles. Through the cooperation of the moving components and the spray components, the quality of bottle sterilization is improved.
[0008] Optionally, the moving component further includes: A driven member, which is rotatably connected to the actuating member, is used to control the movement of the actuating member; A driving component is fixedly connected to the inner wall of the sterilization chamber and is used to control the movement of the driven component.
[0009] By adopting the above technical solution, the driving component is activated, causing the driven component to rotate within the mounting frame. This causes the driven component to rotate within the mounting frame, which in turn causes the toggle component to push the placement plate to move on the mounting frame.
[0010] Optionally, the placement plate is provided with multiple placement slots at horizontal intervals.
[0011] By adopting the above technical solution, the placement groove is designed to increase the contact area between the bottle and the placement plate, thereby improving the stability of the bottle during transportation.
[0012] Optionally, the mounting component includes: A limiting plate is horizontally fixed inside the mounting frame, and the limiting plate is parallel to the length direction of the mounting frame; The guide plate is provided in two spaced intervals, and each guide plate is fixedly installed in the mounting frame. The guide plate is parallel to the limiting plate.
[0013] By adopting the above technical solution, the limiting plate and guide plate are used to support the placement plate and assist the actuating rod in rotating within the mounting frame.
[0014] Optionally, the driving element includes: The motor is fixedly installed inside the sterilization chamber, and the output end of the motor is perpendicular to the limiting plate; A drive rod is fixedly mounted on the output shaft of the motor, and the drive rod is perpendicular to the output end of the motor.
[0015] By adopting the above technical solution, the motor is used to drive the drive rod to rotate, and the drive rod is used to drive the driven part to rotate.
[0016] Optionally, the driven member includes: The driven rod, one end of which is rotatably connected to the end of the drive rod away from the motor; A mating rod, one end of which is rotatably connected to the end of the driven rod away from the driving rod, and the other end of which is rotatably connected to the mounting bracket; Both the driven rod and the mating rod are perpendicular to the axis of the motor output end.
[0017] By adopting the above technical solution, the driven rod and the mating rod are configured to convert the rotation of the drive rod into its own rotation, thereby driving the actuating component. Starting the motor causes its output shaft to rotate the drive rod, which in turn drives the driven rod to rotate, and in turn, the driven rod drives the mating rod to rotate.
[0018] Optionally, the driven members are arranged in two sets at intervals, and the driving members are arranged in two sets at intervals, with the driving members and the driven members corresponding one-to-one.
[0019] By adopting the above technical solution and setting two sets of driving and driven components, the rotation of the actuating component within the mounting frame becomes more stable.
[0020] Optionally, the actuating element includes: A toggle lever, which is rotatably connected to the driven lever; A toggle block is provided, with multiple toggle blocks spaced apart along the length of the toggle rod, and each toggle block is fixedly located on the side of the toggle rod away from the ground.
[0021] By adopting the above technical solution, the actuating lever is used to install the actuating block, which is used to push the placement plate to slide on the mounting bracket. When the driven lever drives the mating lever to rotate, since the actuating lever and the driven lever are rotatably connected, the rotation of the driven lever drives the actuating lever to rotate, which in turn drives the actuating block.
[0022] Optionally, the spray element includes: A cylinder, the fixed end of which is fixedly connected to the top of the sterilization box; A spray frame, the top of which is fixedly connected to the telescopic end of the cylinder, and the spray frame is parallel to the placement plate; Steam nozzles are provided at intervals, and each steam nozzle is fixedly installed at the bottom of the spray frame.
[0023] By adopting the above technical solution, the cylinder is used to control the raising and lowering of the spray rack, and the spray rack and steam nozzle are designed to sterilize the bottle. Activating the cylinder extends its telescopic end, causing the cylinder to slide the spray rack downwards within the sterilization chamber, thus allowing the spray rack to pull the steam nozzle into the bottle opening for high-temperature sterilization. When the cylinder's telescopic end retracts, it causes the cylinder to slide the spray rack upwards within the sterilization chamber, thus allowing the spray rack to pull the steam nozzle out of the bottle opening.
[0024] In summary, this utility model embodiment provides a tunnel spray sterilization device, which includes at least one of the following beneficial technical effects: 1. The sterilization box and sterilization chamber are designed to accommodate the mounting rack and spray system. The mounting rack is used to install the moving components, and the placement plate is used to place and move the bottles. When the actuating component rotates within the mounting system, it pushes the placement plate to slide on the mounting rack, thereby moving the bottles. Through the cooperation of the moving components and the spray system, the quality of bottle sterilization is improved.
[0025] 2. The cylinder is used to control the raising and lowering of the spray rack. The spray rack and steam nozzle are designed to sterilize the bottle. Activating the cylinder extends its telescopic end, causing the cylinder to slide the spray rack downwards within the sterilization chamber. This allows the spray rack to pull the steam nozzle into the bottle opening for high-temperature sterilization. When the cylinder retracts its telescopic end, it causes the cylinder to slide the spray rack upwards within the sterilization chamber, allowing the spray rack to pull the steam nozzle out of the bottle opening.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail. Example 1
[0030] Combination Figure 1 and Figure 2 This application discloses a tunnel spray sterilization device, including a sterilization box 1, a mounting frame 2, a spray component 3, and a moving assembly. The sterilization box 1 is set on the ground, and a sterilization chamber 11 is horizontally arranged inside the sterilization box 1. The mounting frame 2 is fixedly set inside the sterilization chamber 11, and the spray component 3 is set inside the sterilization chamber 11. The spray component 3 is slidably connected to the sterilization box 1 to achieve sterilization of the bottle body 7. The moving assembly is set inside the sterilization chamber 11. The moving assembly includes a placement plate 41, a mounting component 42, and a toggle component 43. Multiple placement plates 41 are spaced apart along the length direction of the mounting frame 2. Each placement plate 41 is slidably set inside the sterilization box 1, and the lower end of each placement plate 41 abuts against the upper end of the mounting frame 2. The placement plates 41 are parallel to the width direction of the mounting frame 2. The mounting component 42 is fixedly set inside the mounting frame 2, and the toggle component 43 is slidably set inside the mounting component 42 through the moving assembly to control the movement of the placement plate 41. The moving component also includes a driven member 44 and a driving member 45. The driven member 44 is rotatably connected to the actuating member 43 and is used to control the movement of the actuating member 43. The driving member 45 is fixedly connected to the inner wall of the sterilization chamber 1 and is used to control the movement of the driven member 44. Multiple placement slots 411 are horizontally spaced on the placement plate 41. Two sets of driven members 44 are spaced apart, and two sets of driving members 45 are spaced apart, with each driving member 45 corresponding to one driven member 44.
[0031] In this embodiment, a steam element is provided at the top of the sterilization box 1. The steam element includes a steam box 5 and a steam pipe 6. The steam box 5 is fixedly installed at the top of the sterilization box 1, and the steam pipe 6 is vertically inserted through the top of the sterilization box 1. One end of the steam pipe 6 is fixedly connected to the bottom end of the steam box 5, and the other end of the steam pipe 6 is fixedly connected to a spray element 3. The steam box 5 and the steam pipe 6 are in communication. The steam box 5 is rectangular, the steam pipe 6 is cylindrical, the sterilization box 1 is rectangular, the sterilization chamber 11 is rectangular, the mounting frame 2 is n-shaped, and the placement plate 41 is rectangular. The width of the placement plate 41 shall not be less than the diameter of the bottle 7, and the length of the placement plate 41 shall be consistent with the width of the mounting frame 2. Openings are provided on both sides of the sterilization box 1 near the two ends of the placement plate 41, and the openings are in communication with the sterilization chamber 11. The number of placement plates 41 is sufficient to meet the needs of conveying the bottle 7, and this embodiment does not impose a specific limitation. The placement slot 411 is cylindrical, and its radius is consistent with the radius of the bottom of the bottle 7. The driving component 45 and the driven component 44 are arranged in a one-to-one correspondence; that is, the position of the driving component 45 corresponds to the position of the driven component 44, and the number of driving components 45 corresponds to the number of driven components 44. Activating the spray component 3 and the driving component 45 causes the driving component 45 to drive the driven component 44 to rotate within the sterilization chamber 11. Since the driven component 44 is rotatably connected to the actuating component 43, the driven component 44 drives the actuating component 43 to rotate within the sterilization chamber 11. Because the placement plate 41 is slidably disposed within the sterilization chamber 1, the actuating component 43 pushes the placement plate 41 to slide within the sterilization chamber 1 when rotating, thereby causing the placement plate 41 to move the bottle 7 within the placement slot 411. This allows the spray component 3 to perform high-temperature sterilization on the bottle 7 within the placement slot 411.
[0032] In practical use, after the placement plate 41 is conveyed to the top of the mounting frame 2, the spray component 3 and the drive component 45 are activated, so that the drive component 45 drives the driven component 44 to rotate in the sterilization chamber 11. Since the driven component 44 is rotatably connected to the actuating component 43, the driven component 44 drives the actuating component 43 to rotate in the sterilization chamber 11. Since the placement plate 41 is slidably disposed in the sterilization box 1, the actuating component 43 pushes the placement plate 41 to slide in the sterilization box 1 when rotating, so that the placement plate 41 drives the bottle 7 in the placement slot 411 to move, thereby causing the spray component 3 to perform high-temperature sterilization on the bottle 7 in the placement slot 411.
[0033] Combination Figure 2 and Figure 3Specifically, the mounting component 42 includes a limiting plate 421 and a guide plate 422. The limiting plate 421 is horizontally fixed inside the mounting frame 2 and is parallel to the length direction of the mounting frame 2. Two guide plates 422 are spaced apart, each fixed inside the mounting frame 2 and parallel to the limiting plate 421. The driving component 45 includes a motor 451 and a drive rod 452. The motor 451 is fixed inside the sterilization chamber 1, and its output end is perpendicular to the limiting plate 421. The drive rod 452 is fixed on the output shaft of the motor 451 and is perpendicular to the output end of the motor 451. The driven member 44 includes a driven rod 441 and a mating rod 442. One end of the driven rod 441 is rotatably connected to the end of the drive rod 452 away from the motor 451. One end of the mating rod 442 is rotatably connected to the end of the driven rod 441 away from the drive rod 452. The other end of the mating rod 442 is rotatably connected to the mounting bracket 2. Both the driven rod 441 and the mating rod 442 are perpendicular to the axis of the output end of the motor 451. The actuating member 43 includes an actuating rod 431 and actuating blocks 432. The actuating rod 431 is rotatably connected to the driven rod 441. Multiple actuating blocks 432 are spaced apart along the length of the actuating rod 431, and each actuating block 432 is fixedly disposed on the side of the actuating rod 431 away from the ground. The spraying component 3 includes a cylinder 31, a spraying frame 32, and a steam nozzle 33. The fixed end of the cylinder 31 is fixedly connected to the top of the sterilization box 1. The top of the spraying frame 32 is fixedly connected to the telescopic end of the cylinder 31. The spraying frame 32 is parallel to the placement plate 41. Multiple steam nozzles 33 are arranged at intervals, and each steam nozzle 33 is fixedly installed at the bottom of the spraying frame 32.
[0034] In this embodiment, both the limiting plate 421 and the guide plate 422 are rectangular, and their lengths are consistent with the length of the mounting frame 2. The driving rod 452, the driven rod 441, and the mating rod 442 are all rectangular. The arrangement of the driving rod 452, the driven rod 441, and the mating rod 442 is sufficient to meet the requirement of driving the actuating rod 431 to rotate; this embodiment does not impose specific limitations. The actuating rod 431 is rectangular, and the actuating blocks 432 are square. The length of the actuating rod 431 is consistent with the length of the mounting frame 2, and the distance between the actuating blocks 432 must not be less than the width of the placement plate 41. The motor 451 is started, causing the output shaft of the motor 451 to drive the drive rod 452 to rotate, which in turn drives the driven rod 441 to rotate. The driven rod 441 then drives the mating rod 442 to rotate. Since the actuating rod 431 is rotatably connected to the driven rod 441, the rotation of the driven rod 441 drives the actuating rod 431 to rotate, which in turn drives the actuating block 432 and pushes the placement plate 41 to slide within the sterilization chamber 1.
[0035] The spray rack 32 is rectangular, and the steam nozzles 33 are cylindrical. Each steam nozzle 33 corresponds to a placement slot 411; that is, the position of the steam nozzle 33 corresponds to the position of the placement slot 411, and the number of steam nozzles 33 matches the number of placement slots 411. The length of the spray rack 32 matches the length of the mounting frame 2, and the width of the spray rack 32 matches the width of the mounting frame 2. Activating the cylinder 31 extends its telescopic end, causing the cylinder 31 to slide the spray rack 32 downwards within the sterilization chamber 11. This causes the spray rack 32 to pull the steam nozzles 33 into the bottle opening, thus sterilizing the bottle 7 at high temperature. When the telescopic end of the cylinder 31 retracts, the cylinder 31 causes the spray rack 32 to slide upwards within the sterilization chamber 11, causing the spray rack 32 to pull the steam nozzles 33 out of the bottle opening.
[0036] In practical use, the cylinder 31 is activated, causing the telescopic end of the cylinder 31 to extend, which in turn causes the cylinder 31 to drive the spray frame 32 to slide downward within the sterilization chamber 11. This causes the spray frame 32 to drive the steam nozzle 33 to extend into the bottle mouth, thereby sterilizing the bottle body 7 at high temperature. When the telescopic end of the cylinder 31 is shortened, the cylinder 31 causes the spray frame 32 to slide upward within the sterilization chamber 11, which in turn causes the spray frame 32 to drive the steam nozzle 33 to extend out from the bottle mouth. The motor 451 is started, causing the output shaft of the motor 451 to drive the drive rod 452 to rotate, which in turn drives the driven rod 441 to rotate. The driven rod 441 then drives the mating rod 442 to rotate. Since the actuating rod 431 is rotatably connected to the driven rod 441, the rotation of the driven rod 441 drives the actuating rod 431 to rotate, which in turn drives the actuating block 432 and pushes the placement plate 41 to slide within the sterilization chamber 1. This ensures that the movement of the cylinder 31's extension end is consistent with the transmission of the bottle body 7, thereby completing the spray sterilization of the bottle body 7.
[0037] The implementation principle of this application embodiment is as follows: After the placement plate 41 is conveyed to the top of the mounting frame 2, the cylinder 31 is activated, causing the telescopic end of the cylinder 31 to extend, so that the cylinder 31 drives the spray frame 32 to slide downward in the sterilization chamber 11, thereby causing the spray frame 32 to drive the steam nozzle 33 to extend into the bottle mouth, and then sterilize the bottle body 7 at high temperature; when the telescopic end of the cylinder 31 is shortened, the cylinder 31 drives the spray frame 32 to slide upward in the sterilization chamber 11, thereby causing the spray frame 32 to drive the steam nozzle 33 to extend out from the bottle mouth. The motor 451 is started, causing the output shaft of the motor 451 to drive the drive rod 452 to rotate, which in turn drives the driven rod 441 to rotate. The driven rod 441 then drives the mating rod 442 to rotate. Since the actuating rod 431 is rotatably connected to the driven rod 441, the rotation of the driven rod 441 drives the actuating rod 431 to rotate, which in turn drives the actuating block 432 and pushes the placement plate 41 to slide within the sterilization chamber 1. This ensures that the movement of the cylinder 31's extension end is consistent with the transmission of the bottle body 7, thereby completing the spray sterilization of the bottle body 7. Example 2
[0038] Combination Figure 4 and Figure 5 The sterilization chamber 1 has a water tank 8 at its bottom, and a conveyor belt 81 rotates on the water tank 8. The conveyor belt 81 transports the bottles 7 into the sterilization chamber 1, where they are then sterilized by a spray system 3. Specifically, there are multiple water tanks 8, each equipped with a spray pipe 85. One end of the spray pipe 85 is connected to the water tank 8 via a pump body 84, and the other end is connected to a steam pipe 6. It should be noted that the temperature of each water tank 8 is different; for example, the water temperature in the first water tank 8 is 50°C, the second water tank 8 is 80°C, the third water tank 8 is 60°C, and the fourth water tank 8 is 50°C. Each water tank 8 is equipped with a steam heater 82 to maintain the water temperature. The steam heater 82 can be an electric heating rod or an electric auxiliary heating rod, depending on the actual usage. The conveyor belt 81 is provided with a through hole 83. When water is sprayed from the steam pipe 6 through the steam nozzle 33 onto the bottle 7, the bottle 7 is disinfected. At the same time, the water mist formed flows into the water tank 8 through the through hole 83 of the conveyor belt 81. The water pump in the water tank 8 draws the water in the water tank 8 into the spray pipe 85 for return and next time.
