Description
Technical Field
[0001] This utility model belongs to the field of disinfection channel technology, specifically an automated disinfection channel. Background Technology
[0002] Disposable diapers are single-use products, including baby diapers and adult diapers. They are mainly used for infants, hospitals, and incontinent patients requiring care. Baby diapers are the most common. Because diapers come into direct contact with an infant's skin during use, if they contain bacteria, fungi, or germs, they can easily cause urinary tract infections in infants, adversely affecting their health. Since diaper production still requires manual operation of machinery, disinfection of personnel entering the production area is crucial.
[0003] The existing personnel disinfection channels have a low degree of automation and require manual control by personnel, which poses a high risk of infection. At the same time, the respiratory tract and eyes of personnel are exposed to the air during disinfection, which can easily cause mucosal damage. In order to remove dust from personnel, manual patting is usually used, which can easily cause cross-infection. In addition, the disinfection efficiency is low and there are many disinfection dead spots. Utility Model Content
[0004] To address the problems of low automation in existing disinfection channels, the need for manual dust removal, the potential for disinfectant diffusion to cause respiratory and eye discomfort to employees, low disinfection efficiency, and significant disinfection blind spots, this invention provides an automated disinfection channel.
[0005] This utility model is achieved through the following technical solution: an automated disinfection channel, including a base and a box connected and installed on the base. The box has a channel on each side opposite to the other, an arc-shaped plate between the two channels, and an isolation door on the outside of the two channels. A conical tube capable of generating vortex rings is connected and installed on the arc-shaped plate. A pneumatic solenoid valve is connected and installed at one end of the conical tube. An atomizer is connected and installed on the side wall of the conical tube. A liquid storage tank is connected and installed on the base. A pump body is connected and installed between the liquid storage tank and the atomizer. A fixing frame is connected and installed at the upper end of the arc-shaped plate. A vertical rod is connected and installed at the lower side of the fixing frame. A ring tube is connected and installed at the bottom of the vertical rod. Several fan-shaped nozzles inclined towards the center of the ring tube are spaced around the lower side of the ring tube. A distance measuring sensor is connected and installed at the bottom of the ring tube. The base has a support mesh in the center and a fan on the side wall. A ventilation duct that can guide the air inside the base to the outside is connected to the outside of the fan.
[0006] A further improvement of this utility model is that the vertical rod is a telescopic electric lifting rod.
[0007] A further improvement of this utility model is that a shoe sole cleaning device is connected and installed on the base between the passages on the outdoor side. The shoe sole cleaning device includes an open box and a cover net connected and installed on the top of the open box. A motor is connected and installed on the side wall of the open box. A conveyor roller is rotatably connected between the two side walls of the open box. The conveyor rollers are connected to each other by a conveyor belt. The motor and the conveyor rollers are connected by a belt. The conveyor belt is provided with bristles extending from between the cover nets.
[0008] A further improvement of this invention is that an ultraviolet lamp is connected and installed at the top of the channel.
[0009] A further improvement of this invention is that the fan is a turbofan.
[0010] A further improvement of this utility model is that the outlet of the ventilation pipe is equipped with a backflow preventer valve.
[0011] A further improvement of this utility model is that each isolation door is equipped with an automatic sensor switch.
[0012] As can be seen from the above technical solutions, the beneficial effects of this utility model are: During use, employees open the isolation door from outside the factory, enter the center of the base between the arc-shaped plates through the passage, and after the distance sensor detects someone entering, the pump body is activated to pump disinfectant water to the atomizer. The atomizer fills the entire conical tube cavity with disinfectant water, and the pneumatic solenoid valve is opened instantly, spraying in high-pressure gas to spray the atomized disinfectant water at high speed to form a vortex ring. The vortex ring hits the clothing of the person, so that the disinfectant particles fully combine with the bacteria on the clothing and shake off the dust on the clothing. After a delay, when the disinfectant water is about to spread to the mouth and nose, compressed air is introduced into the ring tube and then sprayed out from the fan-shaped nozzle. The airflow forms an inverted cone-shaped air curtain covering the area above the neck, preventing the disinfectant water from spreading to the respiratory tract and eyes for protection. Finally, the fan is activated to exhaust the air from top to bottom to the outside, carrying away the remaining disinfectant water and dust. After disinfection is completed, the employee enters the factory through the other side passage. This device uses a vortex ring with atomized disinfectant to impact the human body and clothing from all directions. At the same time, the airflow curtain formed by the fan-shaped nozzles can prevent the disinfectant from entering the respiratory tract and eyes. Only a small amount of disinfectant is needed to complete the disinfection, saving the amount of disinfectant used and making the disinfection more efficient and comprehensive.

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0022] like Figure 1-6As shown, an automated disinfection channel includes a hollow base 1 and a box 2 connected and installed on the base 1. Inside the box 2, front and rear channels 3 are respectively located on opposite sides. An arc-shaped plate 4 is provided between the two channels 3. Tempered glass transparent isolation doors 5 are provided on the outer sides of the two channels 3. Several evenly distributed cone tubes 6 capable of generating vortex rings are connected and installed on the arc-shaped plates 4. The diameter of the cone tubes 6 points towards the center. A pneumatic solenoid valve 7 is connected and installed at one end of the cone tube 6. The pneumatic solenoid valve 7 is a direct-acting two-way pneumatic solenoid valve, which can be controlled by a controller to open and close within 30ms. The side walls of the cone tubes 6... A nebulizer 8 is connected and installed. A liquid storage tank 9 for holding disinfectant is connected and installed on the base 1. A pump body 10 is installed between the liquid storage tank 9 and the nebulizer 8 through a water pipe. A fixing frame 11 is connected and installed at the upper end of the arc plate 4. A vertical rod 12 is connected and installed at the lower side of the fixing frame 11. A ring tube 13 is connected and installed at the bottom of the vertical rod 12. Several flat nozzles 14 inclined towards the center of the ring tube 13 are arranged around the bottom of the ring tube 13. An infrared ranging sensor 20 or a radar ranging sensor is connected and installed at the bottom of the ring tube 13. The sensor is electrically connected to the controller. The distance is detected to determine whether someone has entered the disinfection channel. The base 1 has a support net 15 in the center that employees can stand on, and a fan 16 is installed on the side wall of the base 1. The gap between the arc plates 4 is connected to the interior of the base 1 through the support net 15, so that the disinfected air can enter the interior of the base 1 from top to bottom. A ventilation pipe 17 that can guide the air inside the base 1 to the outside is connected to the outside of the fan 16.
[0023] In use, employees open the isolation door 5 from outside the factory, enter the center of the base 1 between the arc-shaped plates 4 through the passage 3. After the distance sensor 20 detects someone entering, it sends a signal to the controller. The controller starts the pump body 10 to pump disinfectant water to the atomizer 8. The atomizer 8 fills the entire conical tube 6 cavity with disinfectant water. The pneumatic solenoid valve 7 is controlled to open and close instantly, and high-pressure gas is sprayed in to spray the atomized disinfectant water at high speed from the conical tube 6 to form a vortex ring. The vortex ring hits the clothing of the person, so that the disinfectant particles fully combine with the bacteria on the clothing and kill the bacteria. It also shakes off the dust on the clothing. After a delay, just before the disinfectant water spreads to the mouth and nose... During the disinfection process, the controller activates the solenoid valve to introduce compressed air into the ring pipe 13, which then exits through the fan-shaped nozzles 14. The airflow forms an inverted cone-shaped air curtain covering the area above the neck, preventing the disinfectant from spreading into the respiratory tract and eyes. Finally, upon completion of disinfection, the fan 16 is activated to exhaust air from top to bottom to the outside, and the exhaust air is properly treated to remove residual disinfectant and dust. All inhaled air is filtered clean air from within the factory, and the compressed air is also filtered. After disinfection, the equipment stops operating and prepares for the next disinfection cycle. Personnel enter the factory through another passage. This device uses a vortex ring carrying atomized disinfectant to impact clothing from all directions, while the airflow curtain formed by the fan-shaped nozzles 14 prevents disinfectant from entering the respiratory tract and eyes, causing damage and discomfort. Only a small amount of disinfectant is needed for comprehensive disinfection, saving disinfectant usage, time, and improving disinfection efficiency.
[0024] The vertical rod 12 is a retractable electric lifting rod, using a Lesterno 24V DC electric actuator. The pipe supplying compressed air to the ring pipe 13 is made of wear-resistant rigid pipe, which slides through the fixed frame 11, ensuring smooth up and down extension and preventing the pipe from getting stuck during sliding. The distance sensor 20 detects the height of the personnel and then transmits the signal to the electric lifting rod to raise and lower the ring pipe 13 to the appropriate position, ensuring that the fan-shaped nozzles 14 can accurately cover the area above the neck with the air curtain, which can not only effectively eliminate bacteria, but also provide sufficient protection for the personnel.
[0025] Among them, a shoe sole cleaning device 18 is connected and installed on the base 1 between the passages 3 near the outdoors. The shoe sole cleaning device 18 includes an opening box 181 and a cover net 182 connected and installed on the top of the opening box 181. The cover net 182 is in the shape of a horizontal grid. A motor 183 is connected and installed on the side wall of the opening box 181. A conveyor roller 184 is rotatably connected between the two side walls of the opening box 181. The conveyor rollers 184 are connected to each other by a conveyor belt 185. The motor 183 is connected to the conveyor rollers 184 by a belt. The conveyor belt 185 is provided with bristles 186 extending from between the cover nets 182. The cover net 182 is provided with baffles around its perimeter to cover the surrounding area. When personnel enter passage 3 and step on the cover net 182, the motor 183 drives the conveyor belt 185 to operate, which in turn causes the bristles 186 to brush over the soles of the shoes, brushing off the dust and placing it on the conveyor belt 185. The conveyor belt 185 rotates, transferring the dust to the bottom of the opening box 181. The opening box 181 is embedded and is regularly dusted to ensure that the inside of the opening box is clean.
[0026] The top of passage 3 is equipped with an ultraviolet lamp 19. When there are no people inside, the ultraviolet lamp 19 can be turned on to thoroughly sterilize passage 3 and improve the level of environmental hygiene.
[0027] Among them, fan 16 is a turbofan. Turbofans have greater suction power, are quieter, and can better suck dust, bacteria, and insects out of the disinfection channel, ensuring hygiene in the factory.
[0028] The outlet of the ventilation pipe 17 is equipped with a backflow preventer valve 21. This prevents external insects, dust, and other contaminants from entering and affecting the exhaust efficiency.
[0029] Each isolation door 5 is equipped with a sensor-operated automatic switch 51. The sensor-operated automatic switch 51 uses a SlimdriveEMD-F single-leaf swing door drive and can sense human images, microwaves, and infrared signals. It can also automatically perform employee attendance tracking via facial recognition, preventing two or more people from entering simultaneously and affecting disinfection effectiveness. When a person is detected at the door and no one is being disinfected inside, the isolation door 5 can be automatically opened, preventing employees from touching the door handle and reducing the risk of cross-contamination.
[0030] In use, when employees are outside the passage, the automatic sensor switch opens the isolation door 5. After personnel enter the passage 3, the door closes. The shoe cleaning device 18 cleans the soles of the personnel's shoes. The personnel enter the center of the base 1 between the arc plates 4 through the passage 3. After the distance sensor 20 detects that someone has entered, it automatically adjusts the height of the ring tube 13. The fan-shaped nozzle 14 blows an air curtain to shield the area above the employee's neck. The pump body 10 is activated to pump disinfectant water to the atomizer 8. The atomizer 8 fills the entire cone tube 6 cavity with disinfectant water. The pneumatic solenoid valve 7 is controlled to open and close instantly. High-pressure gas is injected, causing atomized disinfectant to be sprayed at high speed from the conical tube 6, forming a vortex ring. The vortex ring impacts the clothing at a certain speed, allowing the disinfectant particles to fully combine with bacteria on the clothing, thereby killing the bacteria and shaking off dust. At the same time, a turbine fan is activated to exhaust clean air from inside the factory from top to bottom to the outside, carrying away bacteria, disinfectant, dust, or insects. After disinfection is completed, the relevant equipment stops working and is ready for the next disinfection. Personnel enter the factory through another passage 3. When no one is around at night, the ultraviolet lamp 19 is turned on for disinfection. This device uses a vortex ring with atomized disinfectant to impact clothing, while the airflow curtain formed by the fan-shaped nozzle 14 prevents disinfectant from entering the respiratory tract and eyes, causing damage and discomfort. Only a small amount of disinfectant is needed to complete the comprehensive disinfection, saving disinfectant consumption, improving disinfection efficiency, and saving time.
[0031] The controller can be a common PLC controller, such as the Siemens S7-200 series, which has high reliability, anti-interference ability, can coordinate and control the linkage control of various moving parts, realize infrared detection function, and actively cut off power when no one is around, thus achieving energy saving.
