Description

Technical Field

[0001] This utility model relates to the field of hazardous waste storage technology, and in particular to a storage device for hazardous waste treatment. Background Technology

[0002] Hazardous waste storage devices are sealed equipment specifically designed for the temporary storage of hazardous waste. They must comply with the "Standard for Pollution Control of Hazardous Waste Storage." The main body is typically made of corrosion-resistant materials and equipped with a double-sealed structure to prevent leakage and volatilization. Some devices also include temperature control and explosion-proof functions. A gas collection port is located at the top, connecting to a waste gas treatment device. A leak-proof tray is located at the bottom, along with a liquid level monitoring device. The exterior must be labeled with hazard identification, waste category, and storage time limit. These devices are typically used for temporary storage by waste-generating units or for transfer within treatment plants, ensuring safe management before transportation.

[0003] Hazardous waste storage facilities are based on isolation and protection, risk control, and standardized management. They utilize corrosion-resistant and leak-proof sealed structures to prevent waste from contacting the external environment and to prevent leakage and contamination of soil and water. The facilities employ a categorized and zoned design, physically isolating wastes according to their chemical properties to avoid hazardous reactions caused by mixed storage. Simultaneously, an integrated waste gas collection system uses negative pressure to adsorb escaping gases and guides them into the treatment equipment for purification; temperature control and explosion-proof components monitor the internal environment in real time, triggering warnings when standards are exceeded; external labeling and ledger management ensure waste traceability and strictly control storage time limits, providing a safe transition for subsequent transportation and treatment.

[0004] In existing technologies, some hazardous waste storage devices may tip over during transportation due to shaking. The sealing structure of the device may be damaged by impact, causing the internal hazardous waste to leak out, polluting the soil, water and air, and harming the ecological environment. If the waste is flammable or explosive, the leak may cause an explosion or fire if it comes into contact with an open flame. The spread of toxic substances may threaten the health of people in the surrounding area and even cause poisoning accidents. Therefore, a hazardous waste storage device is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a storage device for hazardous waste treatment, comprising a support 1. The support 1 is the basic support structure of the entire fixed assembly, providing a platform for the installation and bearing of all components such as the electric push rod 2, the rotating shaft 4, and the support shaft 7. The support 1 is also connected to a transport device. The electric push rod 2 is fixedly connected inside the support 1, and its drive end is capable of telescopic movement. This movement drives the connected rack 3 to achieve displacement, providing initial power for the transmission of the entire fixed assembly.

[0033] A rack 3 is fixedly connected to the drive end of the electric actuator 2. The main function of the rack 3 is to transmit power. Driven by the electric actuator 2, it slides horizontally. Because it meshes with the pinion 5, it can convert its linear motion into the rotational motion of the pinion 5, thus acting as a bridge for power transmission. A rotating shaft 4 is rotatably connected inside the support 1. The rotating shaft 4 serves as a connection and transmission mechanism, fixing the pinion 5 and the large gear 6 together. When the pinion 5 rotates under the drive of the rack 3, the rotating shaft 4 rotates synchronously, thereby driving the large gear 6 to rotate as well, realizing the transmission of power from the pinion 5 to the large gear 6.

[0034] A small gear 5 is fixedly connected to the outer side of the rotating shaft 4. The small gear 5 converts the linear motion of the rack 3 into its own rotational motion. The outer side of the small gear 5 is meshed with the left side of the rack 3. A large gear 6 is fixedly connected to the outer side of the rotating shaft 4. The large gear 6 rotates under the drive of the rotating shaft 4, which can transmit power to each gear disk 8, ensuring that multiple gear disks 8 can move synchronously. Multiple support shafts 7 are rotatably connected to the top of the support 1. The support shafts 7 provide rotational support for the gear disks 8 and the contact platform 12. The gear disks 8 rotate around the support shafts 7, and the contact platform 12 is mounted on the top of the support shafts 7.

[0035] Multiple support shafts 7 are rotatably connected to gear disks 8 on their outer sides. Driven by a large gear 6, the gear disks 8 rotate, and the connecting rods 9 fixed to their outer sides change position as the gear disks 8 rotate, thereby driving the round rod 10 and the clamping block 11 to move. The outer side of the large gear 6 is meshed with the outer side of the gear disks 8. Connecting rods 9 are fixedly connected to the outer sides of multiple gear disks 8, converting the rotational motion of the gear disks 8 into the oscillation or movement of the round rod 10, thus transmitting force.

[0036] A round rod 10 is fixedly connected to the top of the connecting rod 9. The round rod 10 allows the clamping block 11 to accurately move closer to or away from the storage tank 14. The clamping block 11 is fixedly connected to the top of the round rod 10, and the storage tank 14 is mounted on the side adjacent to the clamping block 11. The clamping block 11 is the component that directly contacts and fixes the storage tank 14. Multiple clamping blocks 11 clamp the storage tank 14 from different directions. Through cooperation with the limiting ring 13, the storage tank 14 is firmly fixed to the contact platform 12, preventing displacement or tipping of the storage tank 14 during storage or transportation. The tops of multiple support shafts 7 are rotatably connected to the contact platform 12, which provides a bottom support surface for the storage tank 14. A sealing assembly is provided at the top of the storage tank 14 to prevent leakage of internal contents.

[0037] Reference Figure 1 , Figure 3 , Figure 4 The sealing assembly includes two protective covers 15, with adjacent sides of the two protective covers 15 fixedly connected to the outside of the storage tank 14. The protective covers 15 provide installation space and protective barriers for components such as the electric push rod 16 and support block 21 inside the sealing assembly, preventing external factors from interfering with the internal components and limiting the range of motion of the V-shaped rod 19. Electric push rods 16 are fixedly connected inside each of the two protective covers 15. The electric push rods 16 are the power source for the sealing assembly, and their drive ends can extend and retract, driving the lifting platform 17 to move up and down.

[0038] The drive end of the electric push rod 16 is fixedly connected to a lifting platform 17. The lifting platform 17 connects the electric push rod 16 and the bracket 18. Driven by the electric push rod 16, it performs lifting and lowering movements, transmitting the power of the electric push rod 16 to the bracket 18, which in turn drives the V-shaped rod 19 to move. Two brackets 18 are fixedly connected to the top of the lifting platform 17. The brackets 18 provide rotational support points for the V-shaped rod 19, allowing the V-shaped rod 19 to rotate around the inner side of the bracket 18.

[0039] Both brackets 18 are rotatably connected to V-shaped rods 19 on their inner sides. The V-shaped rods 19, through their cooperation with the brackets 18 and the fixed column 20, convert the lifting motion of the lifting platform 17 into its own rotational motion. The fixed column 20 is slidably connected inside the V-shaped rods 19. The fixed column 20 provides support and guidance for the rotation of the V-shaped rods 19, restricts the movement trajectory of the V-shaped rods 19, and ensures that it rotates along a predetermined path. On the other hand, through its connection with the support block 21, it transfers part of the force on the V-shaped rods 19 to the support block 21, thereby enhancing the stability of the component.

[0040] A support block 21 is fixedly connected to the outside of the fixed column 20. The support block 21 provides a stable installation base for the fixed column 20, so that the fixed column 20 remains in a fixed position when the V-shaped rod 19 moves, thereby ensuring the movement accuracy and stability of the V-shaped rod 19. An installation block 22 is installed at the top of the V-shaped rod 19. The V-shaped rod 19 clamps the installation block 22, which enables the storage bucket 14 to be connected to the top cover 24.

[0041] A top cover 24 is fixedly connected to the side of the mounting block 22. When the top cover 24 moves downward under the action of the V-shaped rod 19 and contacts the top of the storage tank 14, it can cover the opening of the storage tank 14 and prevent hazardous waste from leaking from the inside of the storage tank 14. A sealing ring 23 is fixedly connected to the top of the storage tank 14. When the top cover 24 is closed, the bottom end of the top cover 24 is in close contact with the sealing ring 23. The sealing ring 23 can fill the gap between the top cover 24 and the storage tank 14, further enhancing the sealing effect and preventing hazardous waste from leaking.

[0042] Reference Figures 2 to 4 The bottom end of rack 3 is slidably connected to the inside of support 1, which provides support for the movement of rack 3 and ensures that rack 3 can stably mesh with pinion 5. The top end of rotating shaft 4 is rotatably connected to the bottom end of contact platform 12, providing support for contact platform 12. The bottom end of large gear 6 is rotatably connected to the top end of support 1, and the bottom end of gear disk 8 is rotatably connected to the top end of support 1. A limiting ring 13 is fixedly connected to the outside of storage tank 14. The limiting ring 13 restricts the clamping block 11 when it is in contact with the surface of storage tank 14, ensuring that storage tank 14 will not shake during transportation. The bottom end of clamping block 11 is in contact with the top end of limiting ring 13.

[0043] The V-shaped rod 19 has a sliding groove inside, and the outer side of the fixed column 20 is slidably connected to the inside of the sliding groove. The bottom end of the support block 21 is fixedly connected to the inside of the protective cover 15, providing stable support for the movement of the V-shaped rod 19. The outer side of the V-shaped rod 19 is rotatably connected to the inside of the fixed column 20. The top end of the sealing ring 23 contacts the bottom end of the top cover 24. The sealing ring 23, the top cover 24, and the storage tank 14 work together to achieve a seal for the device. The V-shaped rod 19 is slidably connected inside the protective cover 15.

[0044] Working principle: When the electric push rod 2 is activated, it begins to rotate, driving the rack 3 connected to its drive end to move. The movement of the rack 3 causes the meshing pinion 5 to rotate. The pinion 5 transmits the motion to the large gear 6 through the rotating shaft 4. The movement of the large gear 6 causes the multiple gear discs 8 connected to its outer side to rotate, thereby driving the connecting rod 9 to move. The movement of the connecting rod 9 drives the clamping block 11 to move through the round rod 10, realizing the inward contraction and outward expansion of the clamping block 11, thus fixing the device and avoiding tipping and collision caused by transportation bumps, sudden braking, etc. This significantly reduces the risk of damage to the storage device and leakage of hazardous waste, ensuring transportation safety, while reducing the wear and tear caused by device shaking and friction, and extending its service life.

[0045] The electric push rod 16 is activated, and it begins to move, driving the lifting platform 17 to move. The movement of the lifting platform 17 drives the support 18 to move, causing the V-shaped rod 19 to rotate around the fixed column 20 as a fulcrum, thereby clamping the mounting block 22 and completing the tight connection between the storage tank 14 and the top cover 24. Pressure is applied to the sealing ring 23 to achieve a seal for the device, preventing the volatilization and diffusion of volatile harmful substances in hazardous waste, avoiding pollution of the atmospheric environment or health hazards to operators, and preventing leakage of liquid hazardous waste due to transportation bumps, spillage, etc., reducing the risk of soil and water pollution, and also reducing the impact of the external environment on the stored waste.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
