Description

Technical Field

[0001] This invention relates to the field of sterilization and disinfection technology, and in particular to a sterilization and disinfection system for borosilicate glass bottles. Background Technology

[0002] Borosilicate glass bottles are bottles made using borosilicate glass material. Borosilicate glass, also known as low-alkali borosilicate glass, is mainly made from raw materials such as borax and quartz sand, and has a low coefficient of thermal expansion and excellent chemical stability. These properties make borosilicate glass bottles widely used in various fields such as pharmaceuticals, food and beverages, and cosmetics.

[0003] Compared to plastic bottles, borosilicate glass bottles, as an environmentally friendly and durable beverage packaging option, have a higher recycling value. For example, glass products such as beer bottles and cola bottles are recyclable. Whether recycled or newly manufactured, glass bottles undergo rigorous sterilization procedures to ensure their internal hygiene meets standards.

[0004] A search revealed Chinese patent CN114425095B, ​​which describes a glass bottle sterilization production line. The line includes a chassis with symmetrically arranged conveyor belts for feeding and discharging on both sides. A turntable is rotatably mounted on the side of the chassis facing the direction of the conveyor belts. Six first support rods are evenly spaced and fixed on the outer circumference of the turntable. A support plate is rotatably mounted on each first support rod. A spray pipe is located in the center of the support plate, with an elongated opening in the upper center of the spray pipe. A first channel is provided inside the spray pipe, and a spray head is slidably mounted within the first channel. Each spray head can slide out of the first channel and has multiple spray holes along its axial direction. A drive module for rotating the turntable is connected to the rear of the turntable, and a supply module for supplying sterilizing solution to the delivery chamber is connected to the turntable.

[0005] While the aforementioned patents can effectively rinse and disinfect the inside of glass bottles, their design primarily focuses on internal disinfection, neglecting the cleaning of external surfaces and lacking effective external cleaning and disinfection capabilities. Furthermore, these patents rely on rinsing with chemical disinfectants and fail to incorporate high-temperature sterilization, thus posing a risk of microbial residue and resulting in unsatisfactory disinfection effects. Summary of the Invention

[0006] The purpose of this invention is to provide a sterilization and disinfection system for borosilicate glass bottles that can simultaneously rinse and disinfect the inside and outside of the glass bottles, as well as simultaneously perform high-temperature sterilization on the inside and outside of the glass bottles, in order to solve the above-mentioned problems.

[0007] This invention achieves the above-mentioned objective through the following technical solution: A sterilization and disinfection system for borosilicate glass bottles, comprising a support frame, a housing mounted on the support frame, a drain pipe connected to the bottom of the housing, a swing frame rotatably connected to the housing via a rotating shaft, a stepper motor mounted on the outer wall of the housing for driving the rotating shaft, rotating rings spaced apart on the swing frame, each rotating ring having a cross support plate connected inside for supporting the glass bottle, a lifting frame on the swing frame, and slotted pressure plates spaced apart on the lifting frame for pressing and fixing the glass bottle to the cross support plate. The swing frame is equipped with a screw motor for driving the lifting frame to rise and fall. Each slotted pressure plate has a rotating nozzle 1 for extending into the glass bottle. The nozzle 1 is fixedly connected to the lifting frame. The inner wall of the box is equipped with nozzles 2 for spraying liquid and high-temperature gas to the outside of the glass bottle. A liquid storage tank is installed on the outer wall of the box, and a liquid injection pipe is connected to the liquid storage tank. The box is equipped with a gas-liquid delivery system for delivering high-temperature gas and liquid in the liquid storage tank to nozzles 1 and 2. The swing frame is equipped with a drive component for driving the rotating ring to rotate.

[0008] Preferably, the gas-liquid delivery system includes an electric switching valve installed on the outer wall of the box. The electric switching valve is connected to the liquid storage tank through a liquid delivery pipe and to the nozzle second through a second delivery pipe. The electric switching valve is equipped with a first delivery pipe and an air injection pipe. The first delivery pipe is connected to the first nozzle through a delivery hose.

[0009] Preferably, a waste heat recovery mechanism is provided between the tank body and the liquid storage tank. The waste heat recovery mechanism includes a cover rotatably connected to the top of the tank body via a rotating shaft, an air inlet hood installed on the cover, a heat conduction pipe installed inside the liquid storage tank, with both the upper and lower ends of the heat conduction pipe extending outside the liquid storage tank, and an exhaust pipe located outside the liquid storage tank connected to the lower part of the heat conduction pipe. The air inlet hood is connected to the heat conduction pipe via a gas delivery hose, and fins are installed at intervals inside the liquid storage tank.

[0010] Preferably, the rotating ring is provided with a centering positioning mechanism for centering the glass bottle. The centering positioning mechanism includes a positioning rod, a spring, a pusher, and a contact rod. Four slides are connected circumferentially on the inner wall of the rotating ring. A positioning rod is slidably provided in each of the four slides. A spring is connected between the positioning rod and the slide. A pusher is slidably provided on the swing frame. A spring is connected between the pusher and the swing frame. The pusher contacts the lifting frame. The lifting frame moves upward and pushes the pusher upward. A contact rod is connected to the lower part of the positioning rod and contacts the pusher. The pusher moves upward and pushes the contact rod to move away from the axis of the rotating ring.

[0011] Preferably, the push frame includes two L-shaped slide plates that are slidably mounted on the swing frame. The L-shaped slide plates are in contact with the lifting frame. A spring is connected between the L-shaped slide plates and the swing frame. A horizontal plate is connected between the bottoms of the two L-shaped slide plates. A rotating sleeve is provided on the horizontal plate at intervals. A cross push plate located inside the rotating ring is connected to the top of the rotating sleeve. The cross push plate is located below the cross support plate. The cross push plate has through slots on all four sides for the positioning rod to slide. The cross push plate is bent downwards on all four sides. The contact rod is in contact with the top of the cross push plate.

[0012] Preferably, the drive assembly includes a rotating rod rotatably connected to the swing frame, with worm gears spaced axially on the rotating rod, a drive motor for driving the rotating rod to rotate mounted on the swing frame, and a worm wheel connected to the outer wall of each rotating ring, with the worm wheel meshing with its corresponding worm gear.

[0013] Preferably, the outer wall of the box is provided with a push-pull mechanism for driving the box lid to open and close. The push-pull mechanism includes a gear shaft rotatably connected to the outer wall of the box, a disc connected to the gear shaft, a connecting rod hinged at the eccentric position of the disc, a connecting plate located outside the box connected to the rotating shaft, the connecting plate being hinged to the connecting rod, a fixing plate connected to the top of the box, a tension spring connecting the fixing plate and the box lid, and a missing gear located outside the box connected to the rotating shaft. The missing gear can mesh with the gear on the gear shaft when rotated.

[0014] Both sides of the cabinet are fitted with transparent windows for viewing the sterilization process of the glass bottles inside.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The lifting frame moves the slotted pressure plate and spray nozzle downwards, pressing and fixing the glass bottle onto the cross support plate. Spray nozzle one is inserted into the glass bottle. A stepper motor drives the rotating shaft to rotate the swing frame downwards into the chamber, thus rotating the glass bottle downwards into the chamber and aligning it with spray nozzle two. The gas-liquid delivery system delivers disinfectant and high-temperature gas sequentially to spray nozzle one and spray nozzle two, thereby simultaneously rinsing and disinfecting the inside and outside of the glass bottle, and simultaneously performing high-temperature sterilization on the inside and outside of the glass bottle. This greatly reduces the risk of microbial residue and significantly improves the disinfection effect. The drive component drives the rotating ring to rotate the cross support plate, thereby rotating the glass bottle to achieve comprehensive disinfection of the inside and outside of the glass bottle.

[0017] 2. By setting up a waste heat recovery and utilization mechanism, the heat in the high-temperature gas can be recovered and utilized to preheat the disinfectant solution to be used in the storage tank, realizing the recovery and utilization of waste heat and achieving the purpose of energy conservation and environmental protection. Preheating the disinfectant solution can not only increase its temperature and enhance the chemical reaction rate, but also help it to react with microorganisms more quickly, thereby accelerating its inactivation process; it also helps to increase the solubility of chemical substances in the disinfectant solution, thereby increasing the effective concentration of the disinfectant solution and improving the disinfection effect.

[0018] 3. With the push-pull mechanism, the lid can be automatically closed on the box body after the swing frame is driven by the rotating shaft to rotate the glass bottle downward into the box. It can also be automatically opened upward when the swing frame is driven by the rotating shaft to rotate the glass bottle upward out of the box, so as to facilitate the loading and unloading of the glass bottle. The whole process does not require manual opening and closing of the lid, which not only saves time and effort, but also significantly improves work efficiency.

[0019] 4. The centering positioning mechanism enables automatic centering of the glass bottle, ensuring that the bottle opening is precisely aligned with the nozzle, allowing the nozzle to be smoothly and accurately inserted into the glass bottle, thus preventing damage to the glass bottle caused by the nozzle pressing or impacting it.

Detailed Implementation

[0030] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] See Figures 1-4A sterilization system for borosilicate glass bottles includes a support 1, a housing 2 mounted on the support 1, a drain pipe 21 connected to the bottom of the housing 2, and a V-shaped design at the bottom of the housing 2 to guide waste liquid to the drain pipe 21. A rotating shaft 3 is rotatably connected to the upper front of the housing 2, and a swing frame 4 is connected to the rotating shaft 3. The swing frame 4 includes two connecting plates 41 connected to the rotating shaft 3, and a connecting seat 42 is connected between the two connecting plates 41. Guide rails are connected to the outer walls of the left and right sides of the connecting seat 42. 43. The connecting seat 42 of the swing frame 4 is provided with at least three rotating rings 5 ​​evenly spaced from left to right. Each rotating ring 5 is connected to a cross support plate 51 for supporting the glass bottle. A lifting frame 6 is slidably provided between the two guide rails 43 on the swing frame 4. The lifting frame 6 includes two L-shaped plates 61 respectively slidably disposed in the two guide rails 43. A slotted lifting plate 62 is connected between the upper parts of the two L-shaped plates 61. The top of the slotted lifting plate 62 is evenly spaced from left to right. At least three mounting plates 63 are provided on the slotted lifting plate 62 of the lifting frame 6, which is evenly spaced from left to right and rotates to press and fix the glass bottle on the cross support plate 51. A lead screw motor 8 is provided on the right guide rail 43 of the swing frame 4. The lead screw of the lead screw motor 8 is threadedly connected to the right L-shaped plate 61 of the lifting frame 6. Each slotted pressure plate 7 has a rotatable nozzle 71 in the middle for extending into the glass bottle. The nozzle 71 is fixedly connected to the mounting plate of the lifting frame 6. On the upper part of the box 2, at least three nozzles 10 are evenly spaced from left to right on the inner front wall for spraying liquid and high-temperature gas to the outside of the glass bottle. A liquid storage tank 11 is installed on the outer rear wall of the box 2. A liquid injection pipe 12 is connected to the upper right side of the liquid storage tank 11. The box 2 is equipped with a gas-liquid delivery system for delivering high-temperature gas and liquid in the liquid storage tank 11 to nozzles 71 and 10. A drive assembly for driving the rotating ring 5 to rotate is provided on the connecting seat 42 of the swing frame 4.

[0032] See Figure 4 The drive assembly includes a rotating rod 91 rotatably connected to the connecting seat 42 of the swing frame 4. The rotating rod 91 is located on the front side of the rotating ring 5. At least three worm gears 92 are axially spaced on the rotating rod 91. A drive motor 93 is installed on the left front side of the connecting seat 42 on the swing frame 4. The output shaft of the drive motor 93 is connected to the rotating rod 91. A worm wheel 94 is connected to the outer wall of each rotating ring 5. The worm wheel 94 meshes with the worm gear 92 located on its front side.

[0033] See Figure 3 The gas-liquid delivery system includes an electric switching valve 131 installed on the outer wall of the right side of the housing 2. The electric switching valve 131 is connected to the storage tank 11 through the delivery pipe 132 and the electric switching valve 131 is connected to the nozzle 10 through the delivery pipe 134. The electric switching valve 131 is equipped with a delivery pipe 133 and an air injection pipe 136. The delivery pipe 133 is connected to the nozzle 71 through the delivery hose 135.

[0034] First, place the borosilicate glass bottle on the cross support plate 51. Then, control the lead screw motor 8 to drive the L-shaped plate 61 on the right side to move downward, thereby driving the entire lifting frame 6 to move downward, which in turn drives the slotted pressure plate 7 and the first spray nozzle 71 to move downward. The first spray nozzle 71 moves downward and inserts into the glass bottle, while the slotted pressure plate 7 moves downward to press and fix the glass bottle on the cross support plate 51. Next, control the stepper motor 31 to drive the rotating shaft 3 to drive the swing frame 4 downward into the box 2, thereby turning the glass bottle downward into the box 2, with the bottle mouth facing downward. Initially, the gas outlet of the gas injection pipe 136 is blocked, and the liquid injection pipe 12 is connected to an external infusion device to inject disinfectant into the storage tank 11. The disinfectant is then fed into the second spray nozzle 10 through the infusion pipe 132 and the second delivery pipe 134. The second spray nozzle 10 sprays disinfectant onto the outer wall of the glass bottle to rinse and disinfect the outside of the glass bottle. Disinfectant is sequentially fed into spray nozzle 71 through delivery pipe 133 and delivery hose 135. Spray nozzle 71 sprays the disinfectant onto the inner wall of the glass bottle to rinse and disinfect the inside, thus achieving simultaneous rinsing and disinfection of the inside and outside of the glass bottle. The drive motor 93 drives the rotating rod 91 to rotate the worm gear 92. Through the meshing of the worm gear 92 and worm wheel 94, the rotating ring 5 drives the cross support plate 51 to rotate, thereby rotating the glass bottle. The slotted pressure plate 7 rotates accordingly, achieving comprehensive rinsing and disinfection of the inside and outside of the glass bottle, improving the rinsing and disinfection effect. Since the bottle opening faces downwards, the disinfectant inside the glass bottle drains downwards, while the waste liquid in the tank 2 is discharged through drain pipe 21.

[0035] After the glass bottle is thoroughly rinsed and disinfected with disinfectant, the electric switching valve 131 is activated to release the blockage at the outlet of the gas injection pipe 136 and simultaneously block the outlet of the liquid injection pipe 12. Then, a gas delivery device is connected to the gas injection pipe 136 to inject high-temperature gas into it. The high-temperature gas is then fed into the spray nozzle 10 via the delivery pipe 134, which sprays the gas onto the outer wall of the glass bottle for high-temperature sterilization. The high-temperature gas is then sequentially fed into the spray nozzle 71 via the delivery pipe 133 and the delivery hose 135, which sprays the gas onto the inner wall of the glass bottle for high-temperature sterilization. This simultaneous high-temperature sterilization of both the inside and outside of the glass bottle significantly reduces the risk of microbial residue and greatly improves the disinfection effect.

[0036] After the glass bottles undergo high-temperature sterilization, the stepper motor 31 drives the rotating shaft 3 to rotate the swing frame 4 upwards from inside the chamber 2, thus rotating the glass bottles upwards from inside the chamber 2. Next, the lead screw motor 8 drives the L-shaped plate 61 on the right side to move upwards, thereby moving the entire lifting frame 6 upwards, which in turn moves the slotted pressure plate 7 and the spray nozzle 71 upwards. The slotted pressure plate 7 moves upwards to release the glass bottles, and the spray nozzle 71 moves upwards and is pulled out of the glass bottles. The sterilized glass bottles can then be removed, and new glass bottles can be placed for the next round of sterilization.

[0037] See Figures 5-6 A waste heat recovery mechanism is provided between the housing 2 and the storage tank 11. The waste heat recovery mechanism includes a rotating shaft 140 rotatably connected to the rear top of the housing 2. A housing cover 141 is connected to the rotating shaft 140. An air inlet hood 142 is embedded in the housing cover 141. A heat conduction pipe 144 is installed inside the storage tank 11. The heat conduction pipe 144 is S-shaped. Both the upper and lower ends of the heat conduction pipe 144 extend to the outside of the storage tank 11. The lower part of the heat conduction pipe 144 is connected to an exhaust pipe 145 located outside the storage tank 11. The air inlet hood 142 is connected to the heat conduction pipe 144 through a gas delivery hose 143. Fins 146 are installed at intervals inside the storage tank 11.

[0038] The lid 141 is rotated downwards to close onto the chamber 2, preventing high-temperature gas from escaping directly from the chamber 2 during high-temperature sterilization and thus avoiding waste. High-temperature gas is directed through the air inlet hood 142 into the gas delivery hose 143, which then guides the gas into the heat-conducting pipe 144. The heat from the gas is transferred to the disinfectant solution in the storage tank 11 via the heat-conducting pipe 144 and fins 146, preheating the solution and achieving waste heat recovery, thus achieving energy conservation and environmental protection. Preheating the disinfectant solution not only increases its temperature and enhances the chemical reaction rate, facilitating faster interaction with microorganisms and accelerating their inactivation process, but also increases the solubility of chemicals in the solution, resulting in a higher effective concentration and improved disinfection effect. The gas is then discharged through the exhaust pipe 145, while the liquid is discharged from the bottom of the heat-conducting pipe 144. When it is necessary to rotate the glass bottle upwards from the chamber 2 using the swing frame 4, simply rotate the lid 141 upwards to open it.

[0039] See Figures 5-6The outer wall of the box body 2 is provided with a push-pull mechanism for driving the box cover 141 to open and close. The push-pull mechanism includes a gear shaft 151 rotatably connected to the outer wall of the left side of the box body 2. The gear shaft 151 is located behind the rotating shaft 3. A disc 152 is connected to the shaft of the gear shaft 151. A connecting rod 153 is hinged at the eccentric position on the left side of the disc 152. A connecting plate 154 located outside the box body 2 is connected to the left side of the rotating shaft 140. The connecting plate 154 is hinged to the connecting rod 153. Two fixing plates 155 are connected to the top of the box body 2. A tension spring 156 is connected between the fixing plate 155 and the box cover 141. A missing gear 157 located outside the box body 2 is connected to the left side of the rotating shaft 3. The missing gear 157 can mesh with the gear on the gear shaft 151 when rotated.

[0040] When the rotating shaft 3 drives the swing frame 4 downward into the housing 2, it also drives the missing gear 157 to rotate. After the swing frame 4 is inside the housing 2, the missing gear 157 rotates until it meshes with the gear on the gear shaft 151. As a result, the missing gear 157 continues to rotate, driving the gear shaft 151 to drive the disc 152 to rotate. The rotation of the disc 152 pulls the connecting plate 154 downward around the rotating shaft 140 via the connecting rod 153. This drives the rotating shaft 140 to drive the housing cover 141 to rotate downward and close onto the housing 2. The tension spring 156 is then stretched. When the rotating shaft 3 drives the swing frame 4 to rotate upward from inside the box 2, the gear shaft 151 is driven by the missing gear 157 to rotate the disc 152 in reverse. The reverse rotation of the disc 152 pushes the connecting plate 154 to rotate upward around the rotating shaft 140 via the connecting rod 153. This drives the rotating shaft 140 to rotate the box cover 141 upward and open it. The tension spring 156 then returns to its original state. The upward rotation and opening of the box cover 141 is synchronized with the upward rotation of the swing frame 4 from inside the box 2, without hindering the upward rotation of the swing frame 4 from inside the box 2. In this way, the device can automatically close the box cover 141 downward on the box 2 after the rotating shaft 3 drives the swing frame 4 to rotate the glass bottle downward into the box 2, and can also automatically open the box cover 141 upward when the rotating shaft 3 drives the swing frame 4 to rotate the glass bottle upward from inside the box 2, so as to facilitate the loading and unloading of the glass bottle. The whole process does not require manual opening and closing of the box cover 141, which not only saves time and effort, but also significantly improves work efficiency.

[0041] See Figures 7-9The rotating ring 5 is equipped with a centering positioning mechanism for centering the glass bottle. The centering positioning mechanism includes a positioning rod 16, a spring 17, a pusher 18, and a contact rod 20. Four slide rails 52 are evenly spaced along the circumference on the inner wall of the rotating ring 5. The positioning rod 16 is slidably installed in each of the four slide rails 52. A spring 17 is connected between the positioning rod 16 and the slide rail 52. A crossbar is connected in the slide rail 52 and slides through the positioning rod 16. The spring 17 is sleeved on the crossbar and is positioned by the crossbar to prevent the spring 17 from bending. A pusher 18 is slidably installed between the two guide rails 43 on the swing frame 4. The pusher 18 includes two L-shaped slide plates 181 that are slidably installed in the two guide rails 43 respectively. The two L-shaped slide plates 181 contact the two L-shaped plates 61 on the lifting frame 6 respectively. The L-shaped plates 61 move upward and push the L-shaped slide plates 181 upward. The right-side L-shaped slide plate 181 is slidably mounted on the lead screw of the lead screw motor 8. A horizontal plate 182 located below the connecting seat 42 is connected between the bottoms of the two L-shaped slide plates 181. At least three rotating sleeves 183 are evenly spaced from left to right on the horizontal plate 182. A cross push plate 184 located inside the rotating ring 5 is connected to the top of the rotating sleeve 183. The cross push plate 184 is located below the cross support plate 51. The cross push plate 184 has through slots 185 around its perimeter for the positioning rod 16 to slide. The cross push plate 184 is bent downwards around its perimeter. A spring 19 is connected between the top of the L-shaped slide plate 181 of the push frame 18 and the top of the inner side of the guide rail 43 of the swing frame 4. A contact rod 20 that contacts the top of the cross push plate 184 is connected to the lower part of the positioning rod 16. The cross push plate 184 moves upward and pushes the contact rod 20 to move away from the axis of the rotating ring 5.

[0042] Initially, the L-shaped plate 61 on the lifting frame 6 pulls the L-shaped slide plate 181 on the pusher 18, the second spring 19 is in a compressed state, the cross pusher 184 presses the contact rod 20 so that the positioning rod 16 contacts the inner wall of the rotating ring 5, and the first spring 17 is in a stretched state. When the lifting frame 6 moves down, the pusher 18 is released. Under the action of gravity and the reset action of the second spring 19, the entire pusher 18 moves down. When the cross pusher 184 moves down, under the reset action of the first spring 17, it pushes the four positioning rods 16 in the rotating ring 5 to move towards the axis of the rotating ring 5, thereby pushing the glass bottle to the center position, realizing the centering of the glass bottle, and thus enabling the bottle mouth to be accurately aligned with the nozzle 71, ensuring that the nozzle 71 can be smoothly and accurately inserted into the glass bottle, avoiding the nozzle 71 from pressing or hitting the glass bottle and causing damage to the glass bottle. When the rotating ring 5 rotates, it drives the positioning rod 16 to rotate via the slide rail 52. Since the positioning rod 16 is located in the through groove 185 of the cross push plate 184, the rotation of the positioning rod 16 pushes the cross push plate 184 to rotate. When the L-shaped plate 61 on the lifting frame 6 moves up and contacts the L-shaped sliding plate 181 on the push frame 18, the lifting frame 6 continues to move up, pushing the push frame 18 up and compressing the second spring 19. Since the cross push plate 184 is bent downwards on all four sides, the upward movement of the cross push plate 184 pushes the four contact rods 20 in contact with it to move synchronously away from the axis of the rotating ring 5 through its downward-bent slope, thereby driving the four positioning rods 16 to move synchronously away from the axis of the rotating ring 5, releasing the glass bottle, and the first spring 17 is stretched accordingly.

[0043] See Figure 1 Transparent windows 22 are embedded in both the left and right side walls of the box 2, allowing operators to view the disinfection status of the glass bottles inside the box 2 in real time.

[0044] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
