[0006] In the collection container provided by the present invention, dangerous liquid is injected into the interior of the container body from the liquid inlet channel to the liquid outlet channel. When the liquid level of the dangerous liquid in the container body rises to the float position of the float guide groove, the float continuously floats up with the rise of the liquid level until the float floats to the top of the float guide groove.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0027] Embodiment 1:

[0028] join Figure 1 and Figure 2 The present embodiment provides a hazardous liquid collection container, which includes a container body 1 and a self-sealing device 2 for sealing a liquid inlet 101 of the container body, wherein the liquid inlet 101 is arranged at the top of the container body 1, and the self-sealing device 2 includes a self-sealing shell 201, a liquid channel arranged in the self-sealing shell 201, and a float guide groove 204 connected to the liquid channel, wherein the liquid channel includes a liquid inlet channel 202 and a liquid outlet channel 203, and a side wall of the float guide groove 204 is provided with a leakage hole 206, and the leakage hole 206 of the float guide groove is connected to the liquid outlet channel 203. It can be understood that the number of the liquid outlet channels 203 should be consistent with the number of the leakage holes 206. In order to ensure the speed of liquid injection into the container body, the number of the leakage holes should be at least two. Figure 1 and Figure 2 The number of leakage holes 206 shown in the figure is four; a float 205 is placed inside the float guide groove 204, the top of the float guide groove 204 is connected to the liquid inlet channel 202, and the float guide groove 204 provides a floating channel for the float 205. In order to ensure that the float can smoothly float to the top of the float guide groove and block the liquid inlet channel, the inner diameter of the float guide groove 204 should be larger than the outer diameter of the float 205 and smaller than twice the outer diameter of the float; the diameters of the leakage holes 206 and the liquid inlet channel 202 are both smaller than the outer diameter of the float. Preferably, the shape of the float guide groove is a cylinder, the cross-sections at both ends are arc-shaped, and the arc of the arc matches the arc of the float, which can further improve the sealing effect of the float sealing the liquid inlet channel.

[0029] The self-sealing device 2 also includes a signal control module, which includes a magnetic ring circuit and a magnetic ring 208 connected to a controller 211. The controller 211 is used to control subsequent processes. The magnetic ring circuit is composed of a cable 210 and a magnetic ring switch 209. The position of the magnetic ring circuit should ensure that the injected hazardous liquid will not cause damage to the magnetic ring circuit. The magnetic ring circuit is preferably arranged inside the self-sealing shell 201, which not only ensures the safety of the magnetic ring circuit but also simplifies the appearance structure of the self-sealing device.

[0030] The magnetic ring 208 is connected to the float 205 through the connecting rod 207 to form a magnetic floating component. It should be ensured that the buoyancy of the magnetic floating component in the container body 1 is greater than the gravity of the magnetic floating component. In this way, when the float 205 floats up, the magnetic ring 208 can move up with the connecting rod 207. When the float 205 floats to the top of the float guide groove 204, the float 205 blocks the liquid inlet channel 202. At this time, the magnetic force generated by the magnetic ring 208 connected to the float 205 can close the magnetic ring switch 209 to turn on the magnetic ring circuit and send a signal to the controller 211. That is, the maximum straight-line distance that the float 205 moves in the float guide groove 204 should be the straight-line distance from the center point of the magnetic ring to the center point of the magnetic ring switch. In order to ensure that when the float floats to the top of the float guide groove, the magnetic force generated by the magnetic ring can close the magnetic ring switch, the present embodiment is provided with a magnetic ring guide rail 213 in the connecting rod 207 to limit the movement of the magnetic ring 208 in the magnetic ring guide rail 213.

[0031] In the collection container provided in this embodiment, hazardous liquid is injected into the container body 1 from the liquid inlet channel 202 to the liquid outlet channel 203. When the liquid level of the hazardous liquid in the container body 1 rises to the float position of the float guide groove 204, the float continues to float up with the rise of the liquid level until the float floats to the top of the float guide groove. The float 205 blocks the liquid inlet channel 202 to achieve self-sealing of the container. At the same time, the magnetic ring 208 closes the magnetic ring switch to turn on the magnetic ring circuit, and sends a signal to the control terminal on the magnetic ring circuit to achieve control of subsequent process flow.

[0032] It can be imagined that since the liquid collected by the collection container of this embodiment is a hazardous liquid, the float should be made of acid-resistant, alkali-resistant and corrosion-resistant material, and the density of the material should be lower than the density of the collected liquid. The float can be made hollow or solid, but it is necessary to ensure that the buoyancy of the magnetic levitation components including the float in the collected liquid is greater than the gravity of the magnetic levitation components.

[0033] The self-sealing device of the embodiment of the present invention can seal the liquid inlet of the container body by at least one of thread seal, bayonet seal, flange seal, quick interface seal and sealing ring seal. Figure 1 and Figure 2 As shown, the embodiment in the figure adopts a sealing ring sealing method, and a sealing ring 212 is sleeved on the outside of the self-sealing housing 201.

[0034] Furthermore, in the embodiment of the present invention, a liquid outlet 102 is provided at the bottom of the container body 1, and the discharge of the liquid in the collection container is facilitated through the liquid outlet.

[0035] Furthermore, in the embodiment of the present invention, a roller 103 is disposed at the bottom of the container body 1 to facilitate the movement of the collection container.

[0036] The collection container provided in this embodiment can be used to collect dangerous liquids such as radioactive liquids, chemical liquids, and toxic liquids.

[0037] For example, the collection container body is made of radiation-proof material (such as a lead can) or a shielding body is installed on the periphery of the container body, and the collection container provided in this embodiment can be used to collect radioactive liquid. The collected radioactive waste liquid can be stored for natural decay treatment, and the next step of treatment can be carried out when the decay value reaches the standard requirement.

[0038] Embodiment 2:

[0039] This embodiment provides a dangerous liquid collection container, whose structure is the same as that of embodiment 1, except that Figure 3 In this embodiment, the magnetic levitation component is composed of a magnetic ring 208 and a floating ball 205. The magnetic ring 208 is arranged inside the floating ball 205. Compared with the magnetic levitation component of Example 1, the structure of the connecting rod 207 and the magnetic ring guide rail 213 is omitted, and the structure is simpler.

[0040] Embodiment 3:

[0041] join Figure 4 This embodiment provides a hazardous liquid collection system, which includes at least two hazardous liquid collection containers ( Figure 4 Only two are shown in the figure), the liquid inlet 101 of each hazardous liquid collection container is sealed by a self-sealing device 2, and the liquid inlet channel 203 of the self-sealing device 2 is connected to the connecting main pipeline 3 through a self-sealing quick connector 4, and the connecting main pipeline 3 connects each hazardous liquid collection container in series.

[0042] When the collection system provided in this embodiment is collecting liquid, the self-sealing quick connector of the first collection container is in an open state, and the self-sealing quick connectors of the other collection containers are in a closed state, so that the liquid is first injected into the first collection container. When the first collection container is filled with liquid, the self-sealing device seals it and sends a signal to the controller, the controller controls the self-sealing quick connector of the first collection container to close, thereby realizing the double sealing of the container. At the same time, the controller controls the self-sealing quick connector of the second collection container to open, and the liquid is injected into the second collection container. By analogy, the liquid fills each collection container in sequence, thereby realizing the uninterrupted collection of liquid, which can be used in the collection of large quantities of hazardous liquids. At the same time, the collection system of this embodiment installs a self-sealing quick connector at the container inlet, which can ensure that one of the collection containers can be removed at will without liquid spilling, so that after the collection container is full, it can be removed from the system and replaced to ensure the continuous operation of the system.

[0043] Embodiment 4:

[0044] This embodiment provides a dangerous liquid collection system, whose structure is the same as that of embodiment 3, except that Figure 5 The collection container used in the collection system of this embodiment is the hazardous liquid collection container provided in Example 2.
