Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hazardous waste recycling technology, and in particular relates to a hazardous waste recycling and storage device. Background Technology
[0002] Trash cans are containers used to store garbage and are widely used in homes, public places, office areas, and other scenarios. They are important facilities for urban environmental sanitation and garbage classification management. Hazardous waste bins: usually red, mainly collect waste batteries (including mercury batteries), waste light bulbs (fluorescent bulbs), expired medicines, paint cans, empty cosmetic bottles, pesticide cans, etc.
[0003] Because the existing trash can lids and cans do not seal well, the hazardous waste inside leaks out when soaked and squeezed, and then evaporates into the air, thus continuously polluting the surrounding air. This causes the problem of poor sealing of conventional trash cans, which easily pollutes the air.
[0004] Therefore, we propose a hazardous waste recycling and storage device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problem of poor sealing of conventional trash cans, which easily pollute the air, and to propose a hazardous waste recycling and storage device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A hazardous waste recycling and storage device includes a sealed container. A bearing column is fixedly connected to the rear of the sealed container. A sealing cover is affixed to the sealed container, and a spring-loaded lever is movably fitted onto the sealing cover. The tail of the spring-loaded lever is rotatably connected to the bearing column, and a hook is attached to the front of the spring-loaded lever. A spring is provided between the spring-loaded lever and the sealing cover. The lower end of the spring is fixedly connected to the sealing cover, and the upper end of the spring is fixedly connected to the spring-loaded lever. Pressing the spring-loaded lever downwards compresses the spring. Pulling the lever laterally disengages it from the hook, and opening it upwards, the spring-loaded lever acts upwards on the spring, opening the sealing cover. Hazardous waste is placed into the sealed container. The sealing cover is then placed back on the container, and the spring's force acts downwards on the sealing cover, sealing the opening and preventing the continuous leakage of toxic gases, thus reducing pollution.
[0008] Preferably, the sealed container includes a container body, a sealing ring fixedly connected to the upper end of the container body, a sealing cap sealing the sealing ring, a bearing post fixedly connected to the container body, and a hook fixedly connected to the lower end of the hook. The sealing cap firmly presses against the sealing ring, shielding the internal space of the container and preventing the continuous leakage of toxic gases from inside the container.
[0009] Preferably, the elastic pressure rod includes a swing rod, the tail of which is fixedly connected to a rotating shaft, which is rotatably connected to a bearing column. A collar is fixedly connected to the head of the swing rod, and the upper part of the sealing cover is movably inserted through the collar. The upper end of the spring is fixedly connected to the collar, and a spring piece is fixedly connected to the end of the collar facing away from the swing rod. The upper part of the hook is hooked onto the spring piece. Pulling the spring piece to the side disengages it from the hook, and then pulling the elastic pressure rod upwards opens the sealing cover via the spring, facilitating its opening.
[0010] Preferably, the elastic lever further includes a handle, which is fixedly connected to the spring piece. Holding the handle disengages the spring piece from the hook, or re-engages the spring piece onto the hook.
[0011] Preferably, the sealing cover includes a cover plate, the lower part of which is sealed to a sealing ring. A movable column is fixedly connected to the upper end of the cover plate. A spring is movably sleeved on the movable column, and the lower end of the spring is fixedly connected to the cover plate. The movable column movably passes through the sleeve. The spring force acts downward on the cover plate, causing the cover plate to press down onto the sealing ring.
[0012] Preferably, the hook includes a fixing post, the lower end of which is fixedly connected to the barrel body, and a hook body is fixedly connected to the fixing post. The hook body hooks onto the spring sheet. By hooking the hook body onto the spring sheet, the elastic lever is kept in a depressed state.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] 1. Press down on the spring lever to compress the spring downwards. Then pull the spring lever to the side to disengage it from the hook. Open the spring lever upwards, allowing it to exert upward force on the spring, which in turn opens the sealing cap. Place the hazardous waste into the sealed container. Then place the sealing cap on the container. The spring force will exert downward force on the sealing cap to seal the opening of the container, preventing the continuous leakage of toxic gases and reducing pollution.
[0015] 2. Pull the spring piece to the side to disengage it from the hook, then pull the spring lever upward to open the sealing cover via the spring. Attached Figure Description
