Description

Technical Field

[0001] This utility model relates to the field of hazardous waste storage technology, and more specifically, to a hazardous waste storage container with an automatic sealing structure. Background Technology

[0002] Hazardous waste generated during industrial production and laboratory use is diverse, among which liquid hazardous waste containing organic solvents is of particular concern due to its volatility and toxicity. For example, waste liquids containing benzene compounds, chlorinated hydrocarbons, or alcohol solvents readily volatilize at room temperature, producing harmful vapors. Benzene vapor is carcinogenic, chloroform vapor can suppress the central nervous system, and methanol vapor may cause optic nerve damage. The storage of such hazardous wastes requires a balance between airtightness and safety.

[0003] Currently, sealed containers made of corrosion-resistant materials, such as tanks, are commonly used for collection. However, the connection between the pipes used to transport organic solvents and the tanks is prone to aging and damage due to long-term transport of corrosive gases and exposure to the external environment, causing volatile gases to slowly leak from the top gaps. Since such leaks are usually difficult to detect visually, they often pose a hidden risk. Therefore, we propose a hazardous waste storage container with an automatic sealing structure. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a hazardous waste storage container with an automatic sealing structure to solve the technical problem that the volatile gases in existing tanks are prone to overflow and leakage from the connection between the tank and the pipeline when storing organic solvent hazardous waste.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a hazardous waste storage container with an automatic sealing structure, including a tank body, a support fixed in the middle of the tank body, a blocking mechanism A arranged below the support, a blocking mechanism B arranged above the support, and an infusion mechanism arranged on the outer side of the tank body.

[0006] The blocking mechanism A includes a ring basin and a top cover. The ring basin has a recess, and the top cover is suspended from the support by a hanging rod. The lower side of the top cover has a protrusion that is inserted into the recess.

[0007] Preferably, the blocking mechanism B includes a gathering hopper with a leak at the lower end. A sealing block is inserted into the leak. The sealing block has a conical shape. The lower end of the sealing block is connected to the bracket via a telescopic rod. The telescopic rod consists of an inner rod inserted into a sleeve rod.

[0008] Preferably, the blocking mechanism B further includes a bushing that is installed through the middle of the upper part of the outer side of the tank. A bearing is arranged on the upper surface of the bushing, a threaded sleeve is arranged on the upper surface of the bearing, a threaded rod is inserted into the threaded sleeve, a rotating handle is fixed at the upper end of the threaded rod, and the lower end of the threaded rod is connected to the sealing block.

[0009] Preferably, the infusion mechanism includes a pump body A, with a liquid pipe A connected to the input end of the pump body A and a liquid pipe B connected to the output end of the pump body A. One end of the liquid pipe B passes through a sealing joint A and connects to the upper end of the tank, and the sealing joint A is installed through the upper end of the tank.

[0010] Preferably, the infusion mechanism further includes a pump body B, with a liquid pipe C connected to the input end of the pump body B and a liquid pipe D connected to the output end of the pump body B. One end of the liquid pipe D passes through a sealing joint B and connects to the inner side of the tank, and the sealing joint B is installed through the side of the tank.

[0011] Preferably, the sealing joint B penetrates the tank body and is fixedly installed on the inner side wall of the collecting hopper, and one end of the liquid pipe D fixedly installed inside the sealing joint B is tangent to the inner side wall of the collecting hopper.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the design of a notch and a protrusion structure, has the protrusion embedded in the notch within the annular basin due to the influence of the top cover. When organic solvent is transported into the tank and transferred to the top cover via the collection hopper, the organic solvent is evenly transferred into the notch by the protruding structure of the top cover. Once the notch is full, it overflows from the slope beside the notch and flows to the bottom of the tank for storage. At this time, a certain amount of organic solvent remains in the notch. This organic solvent immerses the protrusion, forming a liquid seal at that position. The organic solvent blocks the gas evaporating from the organic solvent in the tank. Thus, after the organic solvent enters the bottom of the tank, the evaporating gas is difficult to be transferred to the top of the tank through the notch and protrusion, preventing the gas from leaking out through the sealing joint A at the top of the tank via the liquid pipe B, thereby improving the safety of the tank for storing organic solvent.

[0014] 2. This utility model, through the structure of liquid pipe C, pump body B and liquid pipe D, allows purified water to be delivered into the collecting hopper, diluting the organic solvent used for liquid sealing in the recess, reducing the amount of organic solvent in the recess, and preventing a large amount of volatile gas from leaking out of the organic solvent used for liquid sealing in the recess. One end of liquid pipe D is installed on the inner side wall of the collecting hopper. When purified water is sprayed into the collecting hopper through the liquid pipe, it will rotate and flow along the wall, which can wash down the organic solvent adhering to the collecting hopper.

[0015] 3. This utility model designs a sealing block and a collection hopper structure. The sealing block is conical in shape and matches the leak at the lower end of the collection hopper. When the sealing block is engaged by the screw and threaded sleeve and moves up and down at the leak position, it changes the state of the collection hopper. When the sealing block rises and matches the leak, it seals the lower end of the collection hopper, preventing gas that accidentally overflows to the liquid seal position from escaping to the upper end of the collection hopper and leaking out through the sealing joint A at the upper end of the tank via liquid pipe B. When the sealing block descends, it separates from the leak. In this way, the organic solvent delivered to the collection hopper by liquid pipe B and the clean water delivered to the collection hopper by liquid pipe D can be transferred to the surface of the top cover through this point, providing a channel for liquid input and a secondary protection effect.

[0025] like Figures 1 to 7As shown, the present invention relates to a hazardous waste storage container with an automatic sealing structure, including a tank body 1, a support 2 fixed in the middle inside the tank body 1, a blocking mechanism A3 arranged below the support 2, a blocking mechanism B4 arranged above the support 2, and an infusion mechanism 5 arranged on the outer side of the tank body 1.

[0026] The blocking mechanism A3 includes an annular basin 301 and a top cover 302. A recess 303 is provided inside the annular basin 301. The top cover 302 is suspended below the support 2 by a hanging rod 304. A protrusion 305 is provided on the lower side of the top cover 302, and the protrusion 305 is inserted into the recess 303. This invention, through the design of the recess 303 and protrusion 305, ensures that the protrusion 305, influenced by the top cover 302, is embedded inside the recess 303 within the annular basin 301. When organic solvent is delivered to the tank 1 and transferred to the top cover 302 via the collecting hopper 401, the organic solvent is evenly distributed into the recess 303 by the protruding structure of the top cover 302. Once the recess 303 is full, it overflows from a slope on one side of the recess 303 and flows into the bottom of the tank 1 for storage. At this time, a certain amount of organic solvent remains in the recess 303, which immerses the protrusion 305 inside, causing it to... The system is designed to form a liquid seal, using organic solvents to block the gas evaporating from the organic solvent inside the tank 1. This prevents the evaporating gas from being transmitted to the top of the tank 1 through the notch 303 and the protrusion 305 after the organic solvent enters the bottom of the tank 1. This also prevents the gas from leaking out through the sealing joint A504 at the top of the tank 1 via the liquid pipe B503, thus improving the safety of the tank 1 for storing organic solvents. The tank 1 is made of fluoroplastic material through a composite process, which has the advantages of strong corrosion resistance, wide temperature range, and anti-aging properties. It is also transparent, making it easy for staff to observe the liquid level inside the tank 1.

[0027] In an embodiment of this utility model, the blocking mechanism B4 includes a gathering hopper 401, with a drain 402 at its lower end. A sealing block 403 is inserted into the drain 402. The sealing block 403 has a conical shape, and its lower end is connected to the bracket 2 via a telescopic rod 404. The telescopic rod 404 consists of an inner rod inserted into a sleeve rod. The sealing block 403 of this utility model is made of fluororubber material, which has good resistance to organic solvent corrosion and flexibility. When the sealing block 403 is pressed against the drain 402, it can provide a flexible seal. By designing the structure of the sealing block 403 and the gathering hopper 401, the sealing block 403 has a conical shape that matches the drain 402 at the lower end of the gathering hopper 401. When the sealing block 403 is engaged by the threads of the lead screw 408 and the lead sleeve 407 and moves up and down at the drain 402, it changes the state of the gathering hopper 401. The sealing block 403 rises and... When the leak 402 is closed, the lower end of the collecting hopper 401 is sealed, preventing gas that accidentally overflows from the liquid seal position from escaping to the upper end of the collecting hopper 401 and leaking out through the sealing joint A504 at the upper end of the tank body 1 via the liquid pipe B503. When the sealing block 403 descends, it will separate from the leak 402. In this way, the organic solvent delivered to the collecting hopper 401 by the liquid pipe B503 and the clean water delivered to the collecting hopper 401 by the liquid pipe D507 can be transferred to the surface of the top cover 302 through this point, providing a channel for liquid input and a secondary protection effect.

[0028] In an embodiment of this invention, the blocking mechanism B4 further includes a bushing 405 that penetrates and is installed in the middle of the upper part of the outer side of the tank body 1. A bearing 406 is arranged on the upper surface of the bushing 405, and a threaded sleeve 407 is arranged on the upper surface of the bearing 406. A lead screw 408 is inserted into the threaded sleeve 407, and a handle 409 is fixed to the upper end of the lead screw 408. The lower end of the lead screw 408 is connected to the sealing block 403. By designing the structure of the bushing 405 and the bearing 406, this invention allows the handle 409 to rotate with the threaded sleeve 407 at this point, thereby allowing the rotating threaded sleeve 407 to thread-engage the fixed lead screw 408. Through the structure of the threaded sleeve 407 and the lead screw 408, the sealing block 403 can be moved up and down, thereby changing the closed and open state of the leak 402. The installation of the handle 409 makes it easy for the operator to apply rotational force to the lead screw 408, providing a point of force application.

[0029] In an embodiment of this invention, the infusion mechanism 5 includes a pump body A501, an inlet pipe A502 connected to the inlet end of the pump body A501, and an outlet pipe B503 connected to the outlet end of the pump body A501. One end of the infusion pipe B503 passes through a sealing joint A504 and connects to the upper part of the tank body 1, with the sealing joint A504 being installed through the upper part of the tank body 1. This invention, through the design of the infusion pipe A502, pump body A501, and infusion pipe B503, enables the organic solvent to be stored in the tank body 1 to be pumped into its interior, achieving an active delivery effect.

[0030] In an embodiment of this invention, the infusion mechanism 5 further includes a pump body B505. The input end of the pump body B505 is connected to a liquid pipe C506, and the output end of the pump body B505 is connected to a liquid pipe D507. One end of the liquid pipe D507 passes through a sealing joint B508 and connects to the inner side of the tank body 1. The sealing joint B508 is also installed through the side of the tank body 1. This invention, through the structure of the liquid pipe C506, pump body B505, and liquid pipe D507, allows purified water to be delivered to the collecting hopper 401 to dilute the organic solvent used for liquid sealing in the recess 303, reducing the amount of organic solvent in the recess 303 and preventing the leakage of large amounts of volatile organic solvent gas remaining in the recess 303.

[0031] In this embodiment of the invention, the sealing joint B508 penetrates the tank 1 and is fixedly installed on the inner side wall of the collecting hopper 401. One end of the liquid pipe D507 fixedly installed inside the sealing joint B508 is tangent to the inner side wall of the collecting hopper 401. With one end of the liquid pipe D507 installed on the inner side wall of the collecting hopper 401, when purified water is sprayed into the collecting hopper 401 through the liquid pipe D507, it will rotate and flow along the wall surface, washing away any organic solvent adhering to or remaining on the collecting hopper 401.

[0032] Working Principle: This embodiment provides a hazardous waste storage container with an automatic sealing structure. During use, the operator needs to connect an external power source to the container and control its operation via a control panel. The operator must first climb a ladder to the top of the container 1. Once at this position, the operator grips the handle 409 and applies force to rotate it. The rotational force applied to the handle 409 is synchronously transmitted to the threaded sleeve 407. The threaded sleeve 407 rotates on the bushing 405 via the bearing 406. After the threaded sleeve 407 rotates, the threaded rod 408 inserted inside it will be threaded into it. 8 will descend and move within the threaded sleeve 407. The descending threaded rod 408 will move along with the sealing block 403 installed at the bottom, so that the sealing block 403 will be removed from the leak 402, leaving the leak 402 open. At this time, the operator starts the pump body A501 to draw the organic solvent into the container through the liquid pipe A502, and then transports it to the collecting hopper 401 through the liquid pipe B503. The organic solvent entering the collecting hopper 401 will flow through the leak 402 onto the top cover 302, and then flow along the top cover 302 into the recess 303 opened in the annular basin 301. After flowing into the recess 303, it will... The container is filled with water. Once the notch 303 is full, the water overflows through a ramp to the bottom of the tank 1. After the organic solvent to be stored is transferred, a small amount of organic solvent remains in the notch 303. At this time, the operator starts pump B505. Pump B505 draws clean water into the container through liquid pipe C506 and then delivers it to the collection hopper 401 through liquid pipe D507. Since one end of liquid pipe D507 is installed on the inner side of the collection hopper 401, when the clean water is sprayed into the collection hopper 401 through liquid pipe D507, it will rotate and flow along the wall, removing any organic solvent adhering to the collection hopper 401. The organic solvent is flushed down, and the clean water used to rinse the organic solvent is transmitted through the leak 402 to the recess 303, where it mixes with and dilutes the residual organic solvent. This makes the amount of gas volatilized at this point negligible. The liquid remaining in the recess 303 can work with the protrusion 305 to create a liquid seal, preventing the gas volatilized from the bottom of the tank 1 from being transmitted to the top of the tank 1. When the volatilized gas increases the pressure at the bottom of the tank 1, the operator needs to open the pressure relief valve to release the gas and transmit it to the filtration equipment for treatment.
