Description

Technical Field

[0001] This utility model relates to the field of disinfection technology, and in particular to a disinfection device for the entrance of a tobacco seedling greenhouse. Background Technology

[0002] In tobacco cultivation, seedling greenhouses are crucial for seedling cultivation, and their virus control directly impacts tobacco yield and quality. Currently, the problem of virus transmission through contact is particularly prominent during seedling cultivation, especially in the seedling stage. Viruses can easily infiltrate seedlings through contact with personnel or tools, leading to infected seedlings being transplanted later and affecting plant growth.

[0003] In existing tobacco seedling cultivation operations in seedling greenhouses, contact transmission mainly occurs through two channels: direct contact between operators and seedlings, and contact between small seedling tools and seedlings. In actual production, it is common for operators to enter the greenhouse without taking protective measures or following standard disinfection procedures. For example, viruses carried on the operators' hands can be directly transmitted to the seedlings through management operations such as thinning, fixing, and transplanting. Furthermore, unsterilized seedling tools may carry viruses and spread them upon contact with healthy seedlings, or they may become a medium for virus transmission when contacting infected seedlings followed by contact with healthy seedlings.

[0024] Please see Figure 1-4 This utility model provides a disinfection device for the entrance of a tobacco seedling greenhouse, including a disinfection chamber 1, which is a sealed area. The disinfection chamber 1 has a disinfection zone 2 and a drying zone 3. The disinfection chamber 1 has an entrance and an exit. An isolation door 3 is provided between the disinfection zone 2 and the drying zone 3. The disinfection zone 2 is located near the entrance of the disinfection chamber 1. The drying zone 3 is located between the disinfection zone 2 and the exit of the disinfection chamber 1. A hand disinfection component 8 for hand disinfection is provided on one side of the disinfection zone 2. An ultraviolet disinfection lamp 7 and a drying device 6 for drying are provided in the drying zone 3.

[0025] In this application, the disinfection chamber 1 is installed at the entrance of a tobacco seedling greenhouse, with its outlet connected to the entrance. The entrance of the disinfection chamber 1 has a front door 11, and the outlet has a rear door 12. The hand disinfection assembly 8 includes a mounting frame 81, a water spray pipe 86 located at the lower end of the mounting frame 81, and multiple nozzles 82 located at the lower end of the water spray pipe 86. A collection funnel 83 is located below the water spray pipe 86. The mounting frame 81 is L-shaped and includes a horizontal and a vertical section. The vertical section is connected to the inner wall of the disinfection zone 2 by bolts, and the water spray pipe 86 is located at the lower end of the horizontal section. The collection funnel 83 is connected to the inner wall of the disinfection zone 2 by a connecting rod. The larger end of the collection funnel 83 faces upwards, and the smaller end faces downwards. The orthographic projection of the water spray pipe 86 falls within the orthographic projection of the larger end of the collection funnel 83. The lower end of the collecting funnel 83 is connected to a waste liquid collecting tank 85 via a collecting pipe 84. A drain pipe extending from one side of the waste liquid collecting tank 85 into the disinfection zone 2 is provided, and a switch valve is installed on the drain pipe. A disinfectant tank 88 is located outside the disinfection chamber 1, and a submersible pump 89 is installed inside the disinfectant tank 88. A liquid filling port is located at the upper end of the disinfectant tank 88. The submersible pump 89 is connected to a spray pipe 86 via a connecting pipe 87, and an electromagnetic switch valve is installed on the connecting pipe 87. The spray pipe 86 has a rectangular frame structure or a circular ring structure. It should be noted that any parts not described in detail in this application are prior art.

[0026] Specifically, multiple sprayers 5 are installed at the top of the disinfection area 2. The sprayers 5 store disinfectant, and the spray nozzles face the pedestrian space of the disinfection area 2. When people walk in the disinfection area 2, the disinfectant is sprayed in a mist form from the sprayers 5 onto the people's bodies, clothing, and small seedling tools, thereby disinfecting the people's bodies. Depending on the size of the disinfection area 2, the sprayers 211 are selected with appropriate power. When the area of ​​the disinfection area 2 is large, a sprayer 5 with higher power and a larger spray area is selected to ensure that the spraying effect of the area can be maximized and to avoid the inability to fully disinfect each person when there are multiple people in the disinfection area 2.

[0027] Sprayer 5 is a dust suppression sprayer. The dust suppression sprayer uses a high-pressure pump to pressurize water to 50-70 kg, which is then delivered through a high-pressure pipeline to atomize at a high-pressure nozzle, forming a fine, drifting water mist. Because the water mist particles are micron-sized and extremely small, their surface tension is essentially zero. When sprayed into the air, they can quickly adsorb dust particles of various sizes, effectively controlling dust and reducing dust pollution. Furthermore, in this embodiment, the liquid contained in the dust suppression sprayer is a disinfectant, thus achieving effective disinfection while suppressing dust. The spray nozzles of multiple dust suppression sprayers are all directed towards the pedestrian space of the disinfection zone 2, and can be respectively installed on the top, bottom, and side walls of the disinfection zone 2. This allows for multiple, multi-angle spraying of disinfectant to personnel within the disinfection zone 2, avoiding missed areas caused by single-angle, single-time spraying, and thus preventing the safety hazards of untreated areas.

[0028] The drying equipment 6 is a hot air curtain, with its air outlet facing the pedestrian space of the drying area 3. Multiple hot air curtains are used, and ultraviolet disinfection lamps 7 are placed between adjacent hot air curtains. A hot air curtain, also known as a hot air curtain, is an air curtain that sprays out hot air. It is an air curtain equipped with a heating device, which heats the outgoing airflow to the required temperature. A high-speed motor drives a cross-flow or centrifugal fan to generate a powerful airflow, forming an invisible curtain that blocks the alternation of hot and cold air and prevents dust. Because the hot air curtain produces high temperatures and high wind speeds, it can blow off larger volumes of disinfectant from the clothing and skin of workers, while simultaneously evaporating smaller volumes of disinfectant. It is very convenient to use and ideal for drying people completely. Multiple hot air curtains can be staggered, placed at the top, bottom, and left and right side walls of the drying area 3, allowing for multi-angle drying of personnel and avoiding any drying gaps.

[0029] In addition, it includes a control unit, which is connected to the sprayer, the hot air curtain, the submersible pump 89, and the solenoid valve. The control unit is a PLC controller. It also includes an infrared sensor mounted on the mounting bracket 81 for detecting the human body; the infrared sensor is connected to the control unit. The infrared sensor is located at the front horizontal section of the mounting bracket 81.

[0030] Of course, this utility model is not limited to the embodiments described above. Several other embodiments based on the design concept of this utility model are also provided below.

[0031] For example, in other embodiments, unlike the embodiments described above, disinfection mats 4 are laid on the ground at the entrance and exit of the disinfection chamber 1. The disinfection mats 4 need to be made of permeable materials such as felt or cotton so that the disinfectant can soak and saturate them. Both felt and cotton mats are absorbent, capable of absorbing a large amount of disinfectant so that workers can thoroughly disinfect the area when stepping on them. Furthermore, their soft materials provide a comfortable experience when people step on them.

[0032] Disinfectant can be sprayed onto the disinfection mat 4 manually. Specifically, personnel can be arranged to wait at the entrance with a sprayer filled with disinfectant and spray the disinfection mat 4 with disinfectant as needed to ensure that the surface of the disinfection mat 4 is kept wet with disinfectant. This ensures that when personnel step on the disinfection mat 4, there is enough disinfectant to disinfect the soles of their feet, preventing viruses from adhering to the soles of their shoes and being brought into the greenhouse.

[0033] When using this application, personnel open the front door 11 to enter the disinfection chamber 1, step on the disinfection mat 4 at the entrance to disinfect the soles of their feet, and then enter the disinfection area 2.

[0034] Hand disinfection: When a person approaches the hand disinfection unit 8, the infrared sensor on the mounting bracket 81 detects the human body and transmits a signal to the control unit. The control unit then activates the submersible pump 89 and the solenoid valve, spraying disinfectant from the nozzle 82. The person places their hands under the nozzle 82 to disinfect their hands. The disinfected waste liquid falls into the collection funnel 83 and flows through the collection pipe 84 into the waste liquid collection tank 85.

[0035] Whole body disinfection: The control unit starts the sprayer 5, which sprays disinfectant into the pedestrian space of the disinfection area 2 to disinfect the whole body of the personnel and the small seedling tools they hold.

[0036] Entering Drying Zone 3: After disinfection, isolation door 3 opens, personnel enter drying zone 3, and isolation door 3 closes. The control unit activates the hot air curtain and ultraviolet disinfection lamp 7. The hot air curtain blows out hot air to dry the moisture on the personnel, and the ultraviolet disinfection lamp 7 performs ultraviolet disinfection on the personnel or small seedling tools.

[0037] Personnel Exit: After drying and disinfection are completed, the rear door 12 is opened, and personnel leave the disinfection chamber 1, stepping on the disinfection mat 4 at the exit to disinfect the soles of their shoes a second time. Afterwards, personnel enter the greenhouse.

[0038] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
