Description

Technical Field

[0001] The invention belongs to the technical field of sterilization and disinfection, and specifically refers to a filling bottle sterilization device. Background Art

[0002] In modern pharmaceutical, food, beverage and other industries, ensuring the sterility and safety of products is extremely important. Therefore, effective sterilization of filling bottles is the basis for ensuring the quality of end products. During the filling process, if there are microorganisms such as bacteria, viruses, fungi, etc. in the bottle, there will be safety risks due to contamination. Especially for sensitive products that cannot be filled at higher temperatures, sterilization before filling is particularly important.

[0003] Existing sterilization methods mainly include thermal sterilization, chemical disinfection and physical disinfection. Thermal sterilization achieves the effect of eliminating microorganisms through high-temperature treatment, but it is not suitable for heat-sensitive containers and products. Chemical disinfection, especially treatment with liquid disinfectants, such as chlorination disinfection, ethanol disinfection, etc., has the risk of disinfectant residues, which requires sufficient rinsing after sterilization, increasing the processing steps and costs. Physical disinfection such as ultraviolet sterilization is limited by the penetration ability and range of light. In recent years, the use of sterilizing gases, especially gaseous hydrogen peroxide, as a sterilization and disinfection method has received widespread attention. Gaseous hydrogen peroxide has the advantages of strong bactericidal ability, no residue, no need for additional rinsing, and can directly enter the complex spatial structure of the bottle for disinfection. The sterilization process includes delivering gaseous hydrogen peroxide to the inside of the bottle through a specific conveying device, allowing it to fully contact the surface of the bottle to achieve a complete sterilization effect.

[0004] However, the current technology has some obvious defects in actual operation. First, when gaseous hydrogen peroxide is blown into the bottle mouth, due to the influence of the airflow dynamics and the bottle mouth structure, part of the gas may be blocked and cannot completely enter the bottle, which not only causes the gas to escape and waste, but also affects the sterilization effect; secondly, the filling bottle is usually divided into three parts: the bottleneck, the bottle body and the bottle bottom, and the existing air intake mechanism cannot adapt to this structure well, resulting in the inability to effectively transmit gas to every corner of the bottle that needs to be sterilized. At the same time, the sterilization gas entering the center of the bottle is wasted because it cannot contact the bottle surface; in addition, since the gas is usually flowing in the bottle, the contact time with the bottle surface is limited, which limits the sterilization effect; finally, if the sterilization process is completed, it is a big challenge to remove the disinfection gas in the bottle. Once it remains in local areas such as the bottom of the bottle, it will cause subsequent filling to be contaminated, affecting the quality and safety of the product.

[0005] In summary, the existing filling bottle sterilization device has many technical defects in terms of sterilization gas utilization efficiency and subsequent treatment. Therefore, it is urgent to invent a filling bottle sterilization device to solve the above problems. Summary of the invention

[0006] In view of the above situation, the present invention provides a filling bottle sterilization device, which can effectively transport sterilization gas to the vicinity of the inner surface of the bottle body, adapt to the internal structure of the bottle body, realize full-surface closed sterilization, and at the same time avoid the waste of gas dissipation. It can also quickly remove residual sterilization gas after disinfection to ensure that the subsequent filling process is not contaminated.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes a filling bottle sterilization device, comprising a multi-chamber gas isolation chamber, a control terminal is arranged opposite the multi-chamber gas isolation chamber, a preheating treatment channel is arranged in front of the multi-chamber gas isolation chamber and the control terminal, an intermittent dynamic conveyor belt is arranged between the multi-chamber gas isolation chamber and the control terminal, the intermittent dynamic conveyor belt passes through the preheating treatment channel, a multi-channel gas delivery system is arranged between the multi-chamber gas isolation chamber and the upper end of the control terminal, a chain-driven multi-layer valve control mechanism is arranged below the multi-channel gas delivery system, a precision-controlled timing pneumatic lifting mechanism is arranged below the chain-driven multi-layer valve control mechanism, a multi-directional gas replacement mechanism is arranged in a horizontal array on the precision-controlled timing pneumatic lifting mechanism, and bottle blanks are placed in an array below the multi-directional gas replacement mechanism on the intermittent dynamic conveyor belt.

[0008] Furthermore, the multi-directional gas displacement mechanism includes a hollow ring, which is arranged above the bottle blank, and is a hollow structure. The hollow ring is arranged with upper and lower openings, and the diameter of the lower opening of the hollow ring is equal to the diameter of the bottleneck of the bottle blank, so as to seal the bottle blank. An annular grille is arranged on the edge of the lower opening of the hollow ring, which is used to divide the passing airflow with equal pressure, and the annular grille is coaxially fixed between the upper and lower walls of the hollow ring. A hollow column is fixed in the upper opening of the hollow ring, and a cavity is opened in an annular manner inside the side wall of the hollow column. The lower part of the core column is provided with a ventilation port in an array outside the cavity, and the hollow column is provided with a flexible cover on the sealing sleeve outside the ventilation port. The flexible cover can be expanded after air passes through the ventilation port. The radius difference between the hollow column and the bottleneck of the bottle blank is equal to the radius difference between the flexible cover after stretching and the body of the bottle blank. When the hollow ring is in close contact with the bottle blank, the distance between the bottom surface of the flexible cover after stretching and the bottom of the bottle blank is equal to the radius difference between the hollow column and the bottleneck of the bottle blank, so that the gas has the same travel cross-section in the process of entering the bottle blank from the annular grille to being discharged from the hollow column, so that the airflow is more stable.

[0009] Furthermore, the multi-directional gas replacement mechanism includes a sterilization hose, a clean hose, a negative pressure hose, an air hose and an exhaust hose. The sterilization hose and the clean hose are respectively sealed and connected and fixed on both sides of the hollow ring. The air hose and the exhaust hose are respectively fixed on one side of the upper part of the hollow column. The air hose and the exhaust hose are connected to the cavity between the sterilization hose and the clean hose to control the expansion and deflation of the flexible cover. The negative pressure hose is fixed on the upper end of the hollow column. The negative pressure hose is sealed and connected to the hollow part of the hollow column to achieve the discharge of the gas injected into the bottle blank. The upper ends of the sterilization hose, the clean hose, the negative pressure hose, the air hose and the exhaust hose are all fixedly connected and provided with a sealing ring. A sealing plug is horizontally slidably provided inside the sealing ring to seal the airflow channel. A sliding column is fixedly provided on one side of the sealing plug. The sliding column is horizontally and tightly inserted into the sealing ring. A first sharp ridge is fixedly provided at one end of the sliding column. A compression spring is fixedly provided between the sealing ring and the first sharp ridge to achieve the resetting of the sealing plug and the first sharp ridge. The compression spring is sleeved on the outside of the sliding column.

[0010] Furthermore, the multi-channel gas delivery system includes a hard pipe, which is fixedly connected to the upper side of the sealing ring, and the upper side of the hard pipe is respectively fixedly connected with a disinfection gas pipeline, a pure gas pipeline, a negative pressure gas pipeline, an air pipeline and an exhaust pipeline, one end of the disinfection gas pipeline, the pure gas pipeline, the negative pressure gas pipeline, the air pipeline and the exhaust pipeline are all sealed and connected with the multi-chamber gas storage cabin, and the other ends of the disinfection gas pipeline, the pure gas pipeline, the negative pressure gas pipeline, the air pipeline and the exhaust pipeline are all fixedly connected with the control terminal, the disinfection gas pipeline is arranged in the same way as the disinfection hose, the pure gas pipeline is arranged in the same way as the pure hose, the negative pressure gas pipeline is arranged in the same way as the negative pressure hose, the air pipeline is arranged in the same way as the air hose, and the exhaust pipeline is arranged in the same way as the exhaust hose.

[0011] Furthermore, the chain-driven multi-layer valve control mechanism includes a motor station, which is respectively fixed on the inner side of the multi-chamber gas isolation cabin and the control terminal. Turntables are arranged in an array directly above the hollow ring between the motor stations. The turntables are arranged in five layers from bottom to top, and adjacent turntables are coaxially fixedly connected. A fixed shaft is passed through the axis of the turntable, and the fixed shaft is rotatably connected to the turntable. The upper end of the fixed shaft is fixedly connected to the negative pressure gas pipeline. Sprockets are coaxially fixed on the upper side of the turntable of the fifth layer and the upper side of the output end of the motor station. Chains are connected to the edges of the sprockets to achieve synchronous rotation of all the sprockets. The turntable of the first layer is sealed with a seal on the disinfection hose. The rings are in the same horizontal plane, the turntable of the second layer and the sealing ring on the negative pressure hose are in the same horizontal plane, the turntable of the third layer and the sealing ring on the pure hose are in the same horizontal plane, the turntable of the fourth layer and the sealing ring on the exhaust hose are in the same horizontal plane, the turntable of the fifth layer and the sealing ring on the air hose are in the same horizontal plane, the turntable is laterally fixed with a second sharp ridge, the second sharp ridges on the turntables of the first layer, the third layer and the fifth layer are arranged on the same side as one, the second sharp ridges on the turntable of the second layer are arranged at intervals of three, and the second sharp ridge on the turntable of the fourth layer is located in the front side of the second sharp ridge on the turntable of the third layer in the clockwise direction.

[0012] Furthermore, the first rib points to the axis of the turntable, and the second rib of the same layer completely presses the first rib sideways to separate the sealing plug from the hard tube, when the second rib of the fifth layer completely opens the sealing plug on the air hose, the second rib of the second layer completely opens the sealing plug on the negative pressure hose, when the second rib of the first layer completely opens the sealing plug on the disinfection hose, the second rib of the second layer completely opens the sealing plug on the negative pressure hose, when the second rib of the third layer completely opens the sealing plug on the pure hose, the second rib of the second layer completely opens the sealing plug on the negative pressure hose, and the second rib of the fourth layer completely opens the sealing plug on the exhaust hose.

[0013] Furthermore, the precise timing pneumatic lifting mechanism includes cylinders, which are respectively fixed on the inner side of the multi-chamber gas storage cabin and the control terminal, and a lifting cross bar is fixed between the output ends of the two cylinders, and the lifting cross bar is fixedly connected to the hollow ring.

[0014] Furthermore, the control terminal controls the output end of the cylinder through a pneumatic control unit and a programmable logic control unit. After the second ridge of the fourth layer completely opens the sealing plug on the exhaust hose, the cylinder lifts the hollow ring away from the bottle blank through the lifting cross bar. Before the second ridge of the fifth layer contacts the first ridge on the air hose, the cylinder lowers the hollow ring through the lifting cross bar to press the bottle blank.

[0015] Furthermore, the control terminal controls the intermittent dynamic conveyor belt through the motor drive unit and the programmable logic control unit. The intermittent dynamic conveyor belt stops moving during the period when the hollow ring is in close contact with the bottle preform, and the intermittent dynamic conveyor belt conveys the bottle preforms in the next row to just below the hollow ring during the period when the hollow column leaves the bottle preform.

[0016] Furthermore, gaseous hydrogen peroxide flows through the disinfecting gas pipeline for sterilizing the bottle blanks, sterile air flows through the pure gas pipeline for replacing the gaseous hydrogen peroxide, the negative pressure gas pipeline is in a negative pressure state for extracting gas, general air flows through the air pipeline for filling the flexible cover, and the exhaust pipeline is connected to the outside atmosphere for deflating the flexible cover.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows:

[0018] (1) The cylinder drives the lifting crossbar and then drives the hollow ring to descend. At this time, the hollow column and the collapsed flexible cover enter the interior of the bottle blank and the hollow ring seals the bottle mouth of the bottle blank. Under the rotation of the motor table, the sprocket is driven by the chain and then the turntable and the second ridge are driven to rotate. Then the second ridge of the fifth layer presses down the first ridge on the air hose to overcome the pressure of the compression spring so that the sealing plug slides and no longer seals the hard tube. At the same time, the second ridge of the second layer opens the sealing plug on the negative pressure hose. At this time, the general air in the air pipeline opens the flexible cover. At the same time, part of the air in the bottle blank is extracted into the negative pressure gas pipeline after passing through the hollow column and the negative pressure hose. Since the flexible cover in the bottle blank is stably opened, the gaseous hydrogen peroxide injected later is only distributed in the area near the inner surface of the bottle blank, thereby reducing the use of gaseous hydrogen peroxide and avoiding waste. The device can adapt to the structural forms of the bottleneck, bottle body and bottle bottom of the general bottle blank and has a wide range of application value. Since the gas has the same travel section from entering the bottle blank to being discharged by the hollow column, the airflow operation is more stable.

[0019] (2) The motor table continues to rotate, so that the second ridge of the first layer completely opens the sealing plug on the sterilization hose and the second ridge of the second layer completely opens the sealing plug on the negative pressure hose. The gaseous hydrogen peroxide in the sterilization gas pipeline is evenly poured into the space formed by the bottle blank, the hollow column and the flexible cover after passing through the sterilization hose, the hollow ring and the annular grille. At the same time, the air originally remaining in the bottle blank is extracted by the negative pressure gas pipeline after passing through the opened negative pressure hose. When the second ridge is away from the first ridge, the sealing plug is reset to reseal the hard tube. At this time, the bottle blank is sealed and filled with gaseous hydrogen peroxide to start sterilizing the inside of the bottle blank. Since the sterilization process of the bottle blank by gaseous hydrogen peroxide is in a sealed state, the leakage of gaseous hydrogen peroxide is prevented and the effect of gaseous hydrogen peroxide on the bottle wall is enhanced. In addition, the positive pressure injection and negative pressure extraction are carried out simultaneously to achieve rapid filling of gaseous hydrogen peroxide and prevent dilution by residual air, thereby improving the sterilization efficiency.

[0020] (3) The second sharp rib of the third layer completely opens the sealing plug on the pure hose, and at the same time, the second sharp rib of the second layer completely opens the sealing plug on the negative pressure hose, and the second sharp rib of the fourth layer completely opens the sealing plug on the exhaust hose. At this time, the sterile air in the pure gas pipeline will enter the bottle blank through the pure hose, and at the same time, the gaseous hydrogen peroxide in the bottle blank will be extracted by the negative pressure gas pipeline. Since the positive pressure injection and negative pressure extraction are carried out simultaneously, the sterile air can quickly replace the gaseous hydrogen peroxide, thereby avoiding the contamination of the subsequent filling by the residual gaseous hydrogen peroxide. Since the gaseous hydrogen peroxide after use is collected by the sealed negative pressure, it is prevented from being released into the air to pollute the environment. At the same time, the exhaust hose is opened to discharge the gas in the flexible cover to the outside through the exhaust pipeline, causing the flexible cover to collapse, thereby realizing the removal of the flexible cover;

[0021] (4) The chain-driven multi-layer valve control mechanism of the device realizes time-sharing control of the multi-layer sealing plugs by setting up a multi-layer turntable and a second pointed ridge structure, thereby realizing multi-directional gas replacement. The originally complex time-sharing control of multiple valves is realized through a simple structure and simple drive, which greatly saves production and operation costs and improves its application value.

[0040] Among them, the chain-driven multi-layer valve control mechanism 7 includes a motor table 71, which is fixedly arranged on the inner side of the multi-chamber gas isolation cabin 1 and the control terminal 2 respectively. A turntable 74 is arranged in an array directly above the hollow ring 91 between the motor tables 71. The turntable 74 is arranged in five layers from bottom to top. Adjacent turntables 74 are coaxially fixedly connected. A fixed shaft 76 is passed through the axis position of the turntable 74. The fixed shaft 76 is rotatably connected to the turntable 74. The upper end of the fixed shaft 76 is fixedly connected to the negative pressure gas pipeline 63. A sprocket 72 is coaxially fixedly arranged on the upper side of the turntable 74 of the fifth layer and the upper side of the output end of the motor table 71. The edge of the sprocket 72 is matched with a chain 73. The turntable 74 of the first layer and the sealing ring 94 on the disinfection hose 911 are in the same horizontal plane. The turntable 74 of the second layer is The turntable 74 on the third layer is at the same horizontal plane as the sealing ring 94 on the pure hose 912, the turntable 74 on the fourth layer is at the same horizontal plane as the sealing ring 94 on the exhaust hose 915, the turntable 74 on the fifth layer is at the same horizontal plane as the sealing ring 94 on the air hose 914, and the turntable 74 is laterally fixed with a second sharp ridge 75.

[0041] Among them, the first rib 953 points to the axis of the turntable 74, the second rib 75 of the same layer completely presses the first rib 953 sideways to separate the sealing plug 95 from the hard tube 66, the second rib 75 of the fifth layer completely opens the sealing plug 95 on the air hose 914, and the second rib 75 of the second layer completely opens the sealing plug 95 on the negative pressure hose 913, the second rib 75 of the first layer completely opens the sealing plug 95 on the disinfection hose 911, and the second rib 75 of the second layer completely opens the sealing plug 95 on the negative pressure hose 913, the second rib 75 of the third layer completely opens the sealing plug 95 on the pure hose 912, and the second rib 75 of the second layer completely opens the sealing plug 95 on the negative pressure hose 913, and the second rib 75 of the fourth layer completely opens the sealing plug 95 on the exhaust hose 915.

[0042] The precise timing pneumatic lifting mechanism 8 comprises a cylinder 81, which is respectively fixed on the inner side of the multi-chamber gas storage cabin 1 and the control terminal 2. A lifting cross bar 82 is fixed between the output ends of the two cylinders 81. The lifting cross bar 82 is fixedly connected to the hollow ring 91. The control terminal 2 controls the output end of the cylinder 81 through a pneumatic control unit and a programmable logic control unit. After the second sharp ridge 75 of the fourth layer completely opens the sealing plug 95 on the exhaust hose 915, the cylinder 81 lifts the hollow ring 91 away from the preform 5 through the lifting cross bar 82. Before the second sharp ridge 75 of the fifth layer contacts the first sharp ridge 953 on the air hose 914, the cylinder 81 lowers the hollow ring 91 and presses the bottle blank 5 through the lifting cross bar 82. The control terminal 2 controls the intermittent dynamic conveyor belt 4 through the motor drive unit and the programmable logic control unit. The intermittent dynamic conveyor belt 4 stops moving during the period when the hollow ring 91 is in close contact with the bottle blank 5. During the period when the hollow column 92 leaves the bottle blank 5, the intermittent dynamic conveyor belt 4 conveys the bottle blank 5 in the next row to the bottom of the hollow ring 91.

[0043] During specific use, the multi-channel gas delivery system 6 is connected to the multi-chamber gas isolation cabin 1 to deliver different gases. The bottle blank 5 first passes through the preheating treatment channel 3 on the intermittent dynamic conveyor belt 4. The preheating treatment channel 3 preheats the bottle blank 5 to prevent condensation when the gaseous hydrogen peroxide and sterile air are injected into the bottle blank 5. The preheated bottle blank 5 runs to the bottom of the hollow ring 91 and stops moving. At this time, the cylinder 81 drives the lifting cross bar 82 and then drives the hollow ring 91 to descend. Since the intermittent dynamic conveyor belt 4 and the cylinder 81 The range of motion and the operating sequence are controlled by the motor drive unit, the pneumatic control unit and the programmable logic control unit are conventional technologies, the operating principle is not repeated here. At this time, the hollow column 92 and the collapsed flexible cover 93 enter the interior of the bottle blank 5 and the hollow ring 91 seals the bottle mouth of the bottle blank 5. At this time, when the motor table 71 rotates The chain 73 drives the sprocket 72 and then drives the turntable 74 and the second rib 75 to rotate. Then the second rib 75 of the fifth layer presses the first rib 953 on the air hose 914 downward to overcome the pressure of the compression spring 952 so that the sealing plug 95 slides and no longer seals the hard tube 66. At the same time, the second rib 75 of the second layer opens the sealing plug 95 on the negative pressure hose 913. At this time, the general air in the air pipeline 64 passes through the air hose 914, the cavity 921 and the ventilation port 922 and enters the flexible cover 93 to open the flexible cover 93. At the same time, part of the air in the bottle blank 5 passes through the hollow column 92 and the negative pressure hose 913 and is drawn into the negative pressure gas pipeline 63. After the second rib 75 is away from the first rib 953, the sealing plug 95 is reset to reseal the hard tube 66. At this time, the flexible cover 93 entering the bottle blank 5 is stably opened.

[0044] The motor table 71 continues to rotate, so that the second sharp ridge 75 of the first layer completely opens the sealing plug 95 on the sterilization hose 911, and the second sharp ridge 75 of the second layer completely opens the sealing plug 95 on the negative pressure hose 913. The gaseous hydrogen peroxide in the sterilization gas pipeline 61 passes through the sterilization hose 911, the hollow ring 91 and the annular grid 916 and is evenly poured into the space formed by the bottle blank 5, the hollow column 92 and the flexible cover 93. At the same time, the air originally remaining in the bottle blank 5 is drawn out by the negative pressure gas pipeline 63 after passing through the opened negative pressure hose 913. When the second sharp ridge 75 is away from the first sharp ridge 953, the sealing plug 95 is reset to reseal the hard tube 66. At this time, the bottle blank 5 is sealed with gaseous hydrogen peroxide and begins to be filled. The interior of the preform 5 is sterilized until the second pointed ridge 75 of the third layer completely opens the sealing plug 95 on the clean hose 912, and the second pointed ridge 75 of the second layer completely opens the sealing plug 95 on the negative pressure hose 913, and the second pointed ridge 75 of the fourth layer completely opens the sealing plug 95 on the exhaust hose 915. At this time, the sterile air in the clean gas pipeline 62 enters the preform 5 through the clean hose 912, and the gaseous hydrogen peroxide in the preform 5 is extracted by the negative pressure gas pipeline 63, so as to replace the gaseous hydrogen peroxide in the preform 5. At the same time, the exhaust hose 915 is opened to discharge the general air in the flexible cover 93 to the outside through the exhaust pipeline 65, so that the flexible cover 93 collapses.

[0045] Then the cylinder 81 drives the lifting cross bar 82 and then drives the hollow ring 91 to rise, bringing the hollow column 92 and the flexible cover 93 out of the bottle blank 5. The sterilized bottle blank 5 without residue is then sent to the next filling process through the intermittent dynamic conveyor belt 4. The bottle blanks 5 in the last row move to the bottom of the hollow ring 91 to start a new sterilization operation.
