Description

Technical Field

[0001] This utility model relates to the technical field of fumigation and disinfection systems, specifically to a safe and automated fumigation and disinfection system. Background Technology

[0002] Fumigation disinfection, as a highly efficient and widely used pest and bacteria control method in warehousing, logistics, containers, wooden packaging, and agricultural product epidemic prevention, can achieve comprehensive and thorough treatment of items in enclosed spaces through gaseous agents. However, traditional fumigation systems have several shortcomings. First, the manual preparation and dosing of chemicals can lead to inaccurate dosage and unsafe operation, easily resulting in waste of chemicals or excessive concentrations that cause damage to goods. Second, the mixing process of chemicals and air relies on manual labor or simple equipment, making it difficult to ensure uniform mixing and resulting in unstable fumigation effects. Third, after fumigation, the exhaust gas is difficult to recover or purify efficiently, and some systems directly emit it, which can easily cause environmental pollution and safety hazards such as poisoning of personnel.

[0003] Currently, some automated fumigation equipment attempts to incorporate electronic weighing, pipeline transportation, and exhaust gas emission modules. However, most of them have a dispersed structure and poor coordination, making it difficult to form a closed-loop control system from chemical preparation and mixing to exhaust gas treatment. This makes them unsuitable for the needs of modern large-scale warehousing or high-frequency fumigation operations. In addition, in existing technologies, the mixing mechanism and the transportation path are often arranged in the same work area, which increases operational risks and is not conducive to the safety management of on-site personnel.

[0004] In view of the above, this application proposes a safe and automated fumigation and disinfection system to solve the above problems. The system should have accurate reagent metering, uniform mixing method, reliable circulating fumigation process, and standardized and environmentally friendly exhaust gas treatment module, so as to fundamentally solve the technical problems of high operation risk, uneven mixing, and environmental pollution of traditional fumigation equipment.

[0027] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] In the description of this utility model, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "upper", "lower", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "end", "head", "tail", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] This application proposes a safe and automated fumigation and disinfection system, which can be referenced as follows:

[0030] For reference Figure 1 This application mainly consists of a fumigation chamber 1 and an equipment room 2 adjacent to the fumigation chamber 1. The equipment room 2 is equipped with a dosing preparation mechanism 21, a chemical delivery pipe 22, a galvanized steel pipe 23, a circulating fan 24, and an exhaust gas recovery mechanism 25. The fumigation chamber 1 is equipped with a chemical mixing mechanism 11, which is connected to the galvanized steel pipe 23. The end of the galvanized steel pipe 23 away from the chemical mixing mechanism 11 is connected to a chimney 26. This enables the equipment room 2 and the fumigation chamber 1 to move in coordination, so that the fumigation agent is evenly mixed with the air before being put into the fumigation chamber, avoiding the harm of high-concentration fumigation agents to goods. Finally, if there is any residual exhaust gas that is difficult to treat, it is discharged through the chimney 26.

[0031] For reference Figure 1The dosing preparation mechanism 21 is connected to the agent delivery pipe 22. The end of the agent delivery pipe 22 away from the dosing preparation mechanism 21 is connected to the galvanized steel pipe 23. The galvanized steel pipe 23 is connected to the agent mixing mechanism 11. Thus, the agent is delivered into the agent delivery pipe 22 through the dosing preparation mechanism 21, then into the galvanized steel pipe 23 through the agent delivery pipe 22, and finally into the agent mixing mechanism 11.

[0032] Furthermore, the dosing preparation mechanism 21 includes a fumigation cylinder 211, an electronic scale 212, a dosing tube 213, and a fumigation vaporization device 214. The fumigation cylinder 211 is used to store fumigation agents. The electronic scale 212 is located at the bottom of the fumigation cylinder 211. The fumigation cylinder 211 is connected to the fumigation vaporization device 214 through the dosing tube 213. The side of the fumigation device 214 away from the dosing tube 213 is connected to the fumigation delivery tube 22. In operation, the required amount of fumigation agent is first weighed by the electronic scale 212 to control the dosage accuracy. The agent enters the fumigation device 214 through the dosing tube 213 to form a gaseous state. After being converted into a gaseous state, the gaseous agent is transported to the fumigation mixing mechanism 11 through the fumigation delivery tube 22.

[0033] During the delivery process, fresh air from outside is simultaneously added to the drug mixing mechanism 11 to mix with the gaseous drug, and a circulating fan 24 is installed to deliver fresh air to the interior; see reference. Figure 1 The circulating fan 24 is connected to external fresh air, galvanized steel pipe 23, and fumigation chamber 1 through three pipes respectively. The pipe in contact with the external fresh air is equipped with an inlet valve 28, which controls the intake of fresh air. After fresh air is drawn in, the circulating fan 24 transmits the fresh air through the pipe to the galvanized steel pipe 23 and simultaneously discharges it into the reagent mixing mechanism 11 for mixing. An intermediate valve 231 is installed in the middle of the galvanized steel pipe 23 to control the flow direction of the mixed gas. At the same time, the intermediate valve 231 also realizes the process switching, flow direction control, and safety isolation of the reagent gas between different sections of the system. The usage of existing common valves will not be described in detail in this application.

[0034] Furthermore, the agent mixing mechanism 11 includes a mixing tank 111, a stirring fan 112, a discharge pipe 113, and a dosing valve 114. The mixing tank 111 is connected to the galvanized steel pipe 23. The stirring fan 112 is installed inside the mixing tank 111, the discharge pipe 113 is installed on one side of the mixing tank 111, and the dosing valve 114 is installed on the discharge pipe 113. Gaseous agents and fresh air enter the mixing tank 111, and the internal stirring fan 112 starts to stir. After stirring is completed, the mixture is discharged into the fumigation chamber 1 through the discharge pipe 113. During the discharge process, the dosing valve 114 controls the discharge.

[0035] After being discharged into the fumigation chamber 1, the circulating fan 24 is restarted, causing the chemical-air mixture in the fumigation chamber 1 to circulate continuously. A return air valve 29 is installed on the pipe connecting the circulating fan 24 and the fumigation chamber 1. The circulating fan 24 and the return air valve 29 promote the formation of an internal circulation, maintaining a uniform distribution of chemical concentration.

[0036] After fumigation, the exhaust gas is drawn into the exhaust gas recovery mechanism 25 by opening the recovery valve 27 for treatment, and finally the treated exhaust gas is discharged into the chimney 26. It should be noted that the intermediate valve 231 is set on the galvanized steel pipe 23 in the middle of the two recovery valves 27. When the exhaust gas is discharged, the intermediate valve 231 can be closed to make the exhaust gas be discharged into the chimney 26 through only one recovery valve 27 for treatment, thus preventing the exhaust gas from flowing back into the fumigation chamber 1.

[0037] Specifically, the exhaust gas recovery mechanism 25 is connected to the galvanized steel pipe 23 through two sets of pipes equipped with recovery valves 27; the exhaust gas recovery mechanism 25 includes a recovery fan 251 and an exhaust gas recovery box 252. The recovery fan 251 is connected to the exhaust gas recovery box 252 through a pipe. The recovery fan 251 and the exhaust gas recovery box 252 are respectively connected to the galvanized steel pipe 23 through two sets of pipes equipped with recovery valves 27; after the recovery valve 27 is opened, the exhaust gas enters the exhaust gas recovery box 252 through the operation of the recovery fan 251 for treatment. After treatment, the exhaust gas is discharged into the chimney 26.

[0038] Furthermore, a high-altitude exhaust valve 232 is installed at the connection between the chimney 26 and the galvanized steel pipe 23. The exhaust gas first enters the galvanized steel pipe 23 through a pipe with a recovery valve 27, and then the exhaust gas is discharged into the chimney 26 by driving the high-altitude exhaust valve 232 to open.

[0039] In view of the above, driving equipment through automated systems and coordinating the driving between valves are common existing technical means, and this application will not elaborate on them further.

[0040] In this invention, the working steps of the device are as follows:

[0041] 1. First, prepare for dosing and vaporization. Store fumigation agent in agent cylinder 211. Weigh the required dosage using electronic scale 212 to ensure dosing accuracy. The agent enters the agent vaporization device 214 through the dosing pipe 213 to complete the vaporization. The gaseous agent enters the agent delivery pipe 22, then enters the galvanized steel pipe 23, and is finally delivered to the agent mixing mechanism 11 (mixing tank 111).

[0042] 2. During the process, the agent mixing and fumigation are carried out. The circulating fan 24 draws in fresh air from the outside, which enters the galvanized steel pipe 23 after being controlled by the inlet valve 28. The gaseous agent and air enter the mixing tank 111 together. The stirring fan 112 operates in the mixing tank to make the agent and air fully mixed. After the mixing is completed, the mixed gas flows into the fumigation chamber 1 through the discharge pipe 113 and is controlled by the dosing valve 114. The circulating fan 24 is started again, and the return air valve 29 is used to realize the gas circulation in the fumigation chamber, ensuring that the agent concentration is evenly distributed and improving the fumigation effect.

[0043] 3. Finally, after fumigation is completed, open the recovery valve 27, and the exhaust gas flows back to the exhaust gas recovery mechanism 25 through the galvanized steel pipe 23. The recovery fan 251 draws the exhaust gas into the exhaust gas recovery box 252 for purification. If there is still exhaust gas that cannot be completely treated, open the high-altitude discharge valve 232, and the exhaust gas is discharged into the air through the chimney 26 to achieve safe disposal.
