Description

Technical Field

[0001] This utility model relates to the field of hazardous materials storage technology, specifically a hazardous waste storage device. Background Technology

[0002] Hazardous waste has properties such as corrosiveness, toxicity, flammability, reactivity, or infectivity. If stored improperly, it can easily cause soil pollution, water pollution, and even endanger human health. Therefore, the proper storage of hazardous waste is a key link in its subsequent safe treatment and disposal.

[0003] Currently, existing hazardous waste storage devices are merely ordinary containers, which make it difficult to achieve independent zoning for the storage of various types of hazardous waste. This can easily lead to the mixing of hazardous wastes of different properties, increasing the difficulty of subsequent treatment and safety risks. Utility Model Content

The technical solution adopted is as follows: it includes an outer barrel, four support legs are fixedly connected to the bottom of the outer barrel, an upper cover that matches the opening at the top of the outer barrel is rotatably connected to the side of the upper end of the outer barrel, a switch assembly is fixedly installed on the side of the outer barrel, a storage barrel is fixedly installed inside the outer barrel, a sorting and feeding mechanism is installed on the outer barrel and the storage barrel, and a discharge mechanism is installed at the bottom of the storage barrel. The sorting and feeding mechanism includes a support plate and a partition. The side of the support plate is fixedly connected to the inner side of the upper end of the outer barrel. A bearing seat is fixedly installed in the middle of the top of the support plate.

Detailed Implementation

[0014] Example 1 like Figures 1 to 4 As shown, this utility model discloses a hazardous waste storage device. The technical solution adopted is as follows: it includes an outer barrel 1, four support legs 2 fixedly connected to the bottom of the outer barrel 1, a top cover 3 rotatably connected to the side of the upper end of the outer barrel 1 to cooperate with the top opening of the outer barrel 1, a switch assembly 4 fixedly installed on the side of the outer barrel 1, a storage barrel 5 fixedly installed inside the outer barrel 1, a sorting and feeding mechanism 6 installed on the outer barrel 1 and the storage barrel 5, a discharge mechanism 7 installed at the bottom of the storage barrel 5, a buckle 10 fixedly connected to the side of the upper end of the outer barrel 1, a connecting hook 11 fixedly connected to the side of the top cover 3 to cooperate with the buckle 10, and a rubber ring 12 fixedly connected to the side of the top cover 3 to correspond to the top of the outer barrel 1. The buckle 10 and the connecting hook 11 are connected to the rubber ring 12 to effectively seal the top opening of the outer barrel 1 and prevent hazardous waste leakage. The sorting and feeding mechanism 6 includes a support plate 63 and a partition plate 65. The side of the support plate 63 is fixedly connected to the inner side of the upper end of the outer barrel 1. A bearing seat 62 is fixedly installed in the middle of the top of the support plate 63. The inner wall of the inner ring of the bearing seat 62 is fixedly connected to the side of the lower end of the feeding hopper 61. Six first magnet pieces 8 are fixedly installed on the side of the upper end of the feeding hopper 61. Second magnet pieces 9, corresponding one-to-one with the six first magnet pieces 8, are fixedly installed on the inner side of the upper end of the outer barrel 1. During sorting and feeding, the feeding hopper 61 only needs to be rotated, and the positioning is achieved by the adsorption effect between the first magnet pieces 8 and the second magnet pieces 9. The operation is simple. Six push rods 13 are fixedly installed on the inner side of the upper end of the feeding hopper 61. The second magnet pieces 9 and the first magnet pieces 13 are connected to the inner side of the outer barrel 1. A magnet 8 has opposite magnetic properties on opposite sides. The lower end of the feed hopper 61 is connected to the upper end of the conveying pipe 64, which is Z-shaped. A partition 65 is fixedly installed inside the storage tank 5. The feed hopper 61, conveying pipe 64, partition 65, and the contact surfaces of the storage tank 5 with hazardous waste are all coated with polytetrafluoroethylene (PTFE). This PTFE coating provides excellent corrosion resistance, adapting to the storage needs of hazardous wastes with different chemical properties and significantly extending the service life of the device. The partition 65 divides the interior of the storage tank 5 into six independent zones, enabling separate storage of six different types of hazardous waste. The feed hopper 61 can rotate flexibly via the bearing seat 62, and in conjunction with the Z-shaped conveying pipe 64, it can accurately guide different hazardous wastes into their corresponding zones, avoiding cross-contamination and facilitating subsequent sorting and processing. It is suitable for temporary storage of hazardous waste in various scenarios such as laboratories and factory workshops. The six-zone storage can meet the classification and storage needs of most small and medium-sized places, and improve the standardization and safety of hazardous waste management.

[0015] The discharge mechanism 7 includes a solenoid valve 71, a discharge pipe 72, and a fixed pipe 73. The fixed pipe 73 is fixedly installed in the through hole on the lower side of the outer barrel 1 and is inclined. There are six discharge pipes 72. The upper ends of the six discharge pipes 72 are connected to the six discharge ports at the bottom of the storage barrel 5, and the lower ends of the six discharge pipes 72 are connected to the inlet on the upper side of the fixed pipe 73. Each of the six discharge pipes 72 is equipped with a solenoid valve 71. The six solenoid valves 71 are electrically connected to the switch group 4. During the discharge process, the switch group 4 controls the solenoid valve 71 of the corresponding area to realize independent discharge of a single area. There is no need for manual contact with hazardous waste, which reduces the number of operation steps and reduces safety hazards, and greatly improves the efficiency of feeding and discharging.

[0016] The working principle of this utility model is as follows: When storing different types of hazardous waste, the top cover 3 can be opened, and the feeding hopper 61 can be rotated by the six push rods 13 on the inner side of the upper end of the feeding hopper 61 according to the type of hazardous waste to be stored. Since the lower end of the feeding hopper 61 is connected to the support plate 63 through the bearing seat 62, the feeding hopper 61 can rotate flexibly, driving the Z-shaped conveying pipe 64 to rotate synchronously. When the conveying pipe 64 is aligned with the target storage area, the first magnet 8 on the side of the feeding hopper 61 and the second magnet 9 at the corresponding position on the inner side of the outer barrel 1 attract each other, realizing the positioning and fixing of the feeding hopper 61. Hazardous waste is poured into the feeding hopper 61, and the waste flows accurately into the corresponding independent area separated by the partition 65 in the storage barrel 5 through the Z-shaped conveying pipe 64, completing the storage of a single type of hazardous waste. By repeating the above steps, different types of hazardous waste can be stored in the other five areas to achieve independent storage in different zones. After storage, the top cover 3 is closed. The top cover 3 is fixed to the top of the outer drum 1 by the connecting hook 11 on the side of the top cover 3 and the buckle 10 on the top of the outer drum 1. At the same time, the rubber ring 12 on the side of the top cover 3 is tightly fitted to the top of the outer drum 1 to achieve sealed storage of hazardous waste and prevent leakage of hazardous waste or diffusion of volatile substances.

[0017] When it is necessary to remove hazardous waste from a specific area, the solenoid valve 71 on the corresponding discharge pipe 72 is opened via the switch assembly 4 on the side of the outer tank 1. The hazardous waste in the storage tank 5 flows into the discharge pipe 72 through the outlet at the bottom of the corresponding area, and then is discharged outside the device through the inclined fixed pipe 73, achieving independent discharge for each area and avoiding mixing of different types of waste. After discharge is completed, the corresponding solenoid valve 71 is closed via the switch assembly 4, restoring the device to a sealed state.
