[0003] Currently, during leaching experiments, the leaching solution is usually replaced manually, and the leaching container is usually cleaned manually between two leaching operations. Manual operation is inefficient and puts operators at risk of exposure to the leaching solution, which can easily affect their health.

[0004] In view of this, this application is hereby filed. Summary of the Invention

[0069] Furthermore, the terms "parallel" and "perpendicular" do not necessarily mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that the direction is more parallel than "perpendicular," not that the structure must be completely parallel, but rather that it can be slightly tilted.

[0070] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "arrange", "mount", "connect" should be understood in a broad sense, for example, it can be fixedly connected, or detachably connected, or integrally connected, it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0071] In order to overcome the deficiencies in the prior art, please refer to Figures 1-5 The embodiment provides an automatic leaching experiment device, which comprises a container body 100, a waste basket 300, a rotating ring 400, a driving shaft 500, an extension arm 510, a sliding sleeve 520 and a matching rod 530.

[0072] The automatic leaching experiment device is used for leaching test on the waste solidified body 2000 to evaluate the stability of the waste solidified body 2000.

[0073] The waste basket 300 is arranged in the container body 100, and the waste basket 300 is used for containing the waste solidified body 2000. When the leaching experiment is carried out, the waste solidified body 2000 is placed in the waste basket 300, and the leaching agent is injected into the container body 100, so that the leaching test is carried out. It can be understood that the waste basket 300 has an opening for the leaching agent to pass through, so that the leaching agent in the container body 100 can be in full contact with the waste solidified body 2000 in the waste basket 300. In the embodiment, the waste basket 300 is made of a mesh plate in a mesh shape, and is not limited thereto. The specific configuration of the waste basket 300 can be flexibly adjusted according to actual needs. Optionally, the waste basket 300 can adopt a detachable form to facilitate the loading and unloading of the waste solidified body 2000.

[0074] It should be noted that when the leaching experiment is carried out, the required leaching agent can be selected according to the specific type of the waste solidified body 2000, and the selection of the leaching agent is not limited in the present application, and can be flexibly selected according to the actual situation.

[0075] The inner side wall of the container body 100 is provided with a containing groove 110, and the containing groove 110 is formed by the radial recess of the inner side wall of the container body 100, and the containing groove 110 continuously extends in the circumferential direction of the container body 100 to form an annular shape. In the embodiment, the container body 100 is in a cylindrical shape, and the groove cavity of the containing groove 110 is in a circular ring shape.

[0076] The rotating ring 400 is housed within the receiving groove 110 and is coaxially disposed with the container body 100. The inner diameter of the rotating ring 400 is the same as that of the container body 100, while the outer diameter of the rotating ring 400 is smaller than the maximum diameter of the circular ring corresponding to the groove cavity of the receiving groove 110. In other words, there is a gap between the groove wall of the receiving groove 110 away from the central axis of the container body 100 and the outer ring wall of the rotating ring 400.

[0077] Along the circumference of the container body 100, the rotating ring 400 can be rotatably engaged with the receiving groove 110, and the side of the rotating ring 400 close to the top wall of the container body 100 is in contact with the side of the receiving groove 110 close to the top wall of the container body 100, and the side of the rotating ring 400 away from the top wall of the container body 100 is in contact with the side of the receiving groove 110 away from the top wall of the container body 100, and the upper and lower sides of the rotating ring 400 are rotatably sealed against the groove wall of the receiving groove 110.

[0078] The outer ring wall of the rotating ring 400 has a first flange 410 and a second flange 420. The first flange 410 and the second flange 420 are both formed by the outer ring wall of the rotating ring 400 protruding along the radial direction of the rotating ring 400, and the first flange 410 and the second flange 420 both extend continuously in an arc shape along the circumference of the rotating ring 400. The first flange 410 and the second flange 420 are spaced apart and distributed in the circumferential direction of the rotating ring 400.

[0079] A third flange 120 is formed on a side wall of the receiving groove 110 away from the central axis of the container body 100 . The third flange 120 extends continuously in an arc shape along the circumference of the container body 100 .

[0080] The groove wall of the receiving groove 110 away from the central axis of the container body 100 is in contact with the first flange 410 , and the groove wall of the receiving groove 110 away from the central axis of the container body 100 is in sliding fit with the first flange 410 .

[0081] The second flange 420 fits in contact with the third flange 120 . Along the circumference of the rotating ring 400 , the second flange 420 and the third flange 120 are slidably matched and a sliding seal is formed therebetween.

[0082] The first flange 410 defines a sliding groove 411 extending along the circumference of the rotating ring 400 . The sliding groove 411 extends continuously into an arc shape and penetrates the rotating ring 400 along the axial direction of the rotating ring 400 .

[0083] The drive shaft 500 is arranged along the axial direction of the rotating ring 400 and passes through the bottom of the container body 100 into the receiving groove 110. The drive shaft 500 extends into the sliding groove 411. The drive shaft 500 is driven by a driver (not shown in the figure).

[0084] A sliding member 412 is slidably engaged within the chute 411, and the drive shaft 500 passes through the sliding member 412. Along the direction of the chute 411, the rotating member slidably engages with the sliding member 412. Along the circumference of the drive shaft 500, the container body 100 and the sliding member 412 are both rotatably engaged with the drive shaft 500.

[0085] An extension groove 130 is defined in the side wall of the receiving groove 110 near the top of the container body 100. The extension groove 130 extends toward the top of the container body 100, and the drive shaft 500 extends into the extension groove 130. A clearance notch 131 is defined in the inner side wall of the container body 100, and the clearance notch 131 communicates with the extension groove 130.

[0086] One end of the extension arm 510 is fixedly connected to the drive shaft 500, while the other end of the extension arm 510 extends into the container body 100 through the clearance notch 131. A sliding sleeve 520 is sleeved over the extension arm 510 and slidably engages with the extension arm 510. A mating rod 530 is fixedly connected to the sliding sleeve 520 and disposed perpendicularly to the extension arm 510. The mating rod 530 extends through the rotating ring 400. Along its axial direction, the mating rod 530 slidably engages with the rotating ring 400, forming a sliding seal between the mating rod 530 and the rotating ring 400.

[0087] The drive shaft 500, the sliding member 412, the rotating ring 400, the extension arm 510, the sliding sleeve 520, and the mating rod 530 are configured such that when the drive shaft 500 is driven by the driver, the drive shaft 500 drives the extension arm 510 to rotate, thereby driving the mating rod 530 via the sliding sleeve 520, so that the mating rod 530 drives the rotating ring 400 to rotate along the circumference of the container body 100. During this process, the rotating ring 400 and the sliding member 412 move relative to each other, that is, the sliding member 412 moves relative to the rotating ring 400 through the sliding groove 411. During this movement, the sliding sleeve 520 can adaptively slide along the extension arm 510, and the mating rod 530 can adaptively slide relative to the rotating ring 400.

[0088] The top of the container body 100 is provided with an input port (not shown). The input port is located on the side of the waste basket 300 near the top of the container body 100. The input port is used to communicate with the leaching agent input pipe (not shown), the cleaning agent input pipe (not shown), and the air input pipe (not shown). The leaching agent input pipe, the cleaning agent input pipe, and the air input pipe are each equipped with a control valve (not shown) to control their connection with the input port. The control valves of the leaching agent input pipe, the cleaning agent input pipe, and the air input pipe are normally closed.

[0089] The third flange 120 defines a first outlet 121 and a second outlet 122. Both the first outlet 121 and the second outlet 122 extend radially from the side of the third flange 120 proximate to the second flange 420 and extend to the outer wall of the container body 100. The first outlet 121 and the second outlet 122 are spaced apart circumferentially along the container body 100. In this embodiment, the inner diameter of the first outlet 121 is smaller than that of the second outlet 122. The first outlet 121 is configured to communicate with a leaching agent collection device (not shown), while the second outlet 122 is configured to communicate with a waste liquid collection device (not shown).

[0090] The second flange 420 defines a first communicating hole 421 and a second communicating hole 422. Both the first communicating hole 421 and the second communicating hole 422 extend radially from the side of the second flange 420 closest to the third flange 120 and extend to the inner wall of the rotating ring 400. The first communicating holes 421 and the second communicating holes 422 are spaced apart circumferentially around the rotating ring 400. The diameter of the first communicating hole 421 matches the inner diameter of the first output port 121, while the diameter of the second communicating hole 422 matches the inner diameter of the second output port 122.

[0091] Wherein, under the driving of the driver, the driving shaft 500 has a first rotation stop point, a second rotation stop point and a third rotation stop point.

[0092] When the drive shaft 500 is at the first rotation dead point, Figure 2 and Figure 5 As shown, the first communication hole 421 is staggered with the first output port 121, and the second communication hole 422 is staggered with the second output port 122. The first output port 121 and the second output port 122 are both closed by the second flange 420. In this state, both ends of the first flange 410 are spaced apart from both ends of the third flange 120.

[0093] When the drive shaft 500 is at the second rotation dead point, Figure 6 and Figure 7 As shown, the first communication hole 421 is connected to the first output port 121, the second communication hole 422 is offset from the second output port 122, and the second output port 122 is closed by the second flange 420. As the drive shaft 500 rotates from the first rotation stop point to the second rotation stop point, the first communication hole 421 gradually connects to the first output port 121, the second communication hole 422 remains completely offset from the second output port 122, and one end of the first flange 410 gradually approaches one end of the third flange 120.

[0094] When the drive shaft 500 is at the third rotation dead point, Figure 8 and Figure 9As shown, the first communication hole 421 is offset from the first output port 121, the second communication hole 422 is connected to the second output port 122, and the first output port 121 is closed by the second flange 420. As the drive shaft 500 rotates from the second rotation stop point to the third rotation stop point, the first communication hole 421 gradually becomes offset from the first output port 121 until they are completely offset, the second communication hole 422 gradually becomes connected to the second output port 122, and one end of the first flange 410 further approaches one end of the third flange 120.

[0095] During use, after solidified waste 2000 is placed in waste basket 300, drive shaft 500 is driven to its first rotational stop. At this point, the control valve of the leaching agent inlet pipe is opened, and the required leaching agent is delivered to container body 100 via the leaching agent inlet pipe, allowing the leaching agent to submerge solidified waste 2000 and lower the leaching agent level below the inlet port. Once the leaching agent is fully delivered, the control valve of the leaching agent inlet pipe is closed again, and the leaching process can then proceed normally.

[0096] When the leaching time is satisfied, the drive shaft 500 is driven to the second rotation stop point, and the control valve of the air inlet pipe is opened simultaneously. At this point, the air inlet pipe is used to balance the air pressure within the container body 100. In this state, the leachate within the container body 100 can enter the leachate collection device through the first connecting hole 421 and the first output port 121.

[0097] After the leachate in the container body 100 is fully discharged, the drive shaft 500 is driven to the third rotation stop point. At this time, the control valve of the air input pipe is closed, and the control valve of the cleaning agent input pipe is opened. The cleaning agent is input into the container body 100 through the cleaning agent input pipe, so that the inner wall of the container body 100 and the surface of the solidified waste body 2000 are cleaned by the cleaning agent. The cleaning agent can enter the waste liquid collection device through the second connecting hole 422 and the second output port 122 to be collected.

[0098] After cleaning is complete, the control valve of the cleaning agent inlet pipe is closed, and the control valve of the air inlet pipe is opened again. A strong airflow is blown into the container body 100 through the air inlet pipe, thereby fully discharging the residual cleaning agent in the container body 100 and promoting rapid drying of the container. The airflow enters the waste liquid collection device, which can be provided with an exhaust mechanism to maintain the internal air pressure balance of the waste liquid collection device, but is not limited thereto. The specific airflow intensity can be flexibly set according to actual needs. It is understood that, generally speaking, the greater the airflow intensity, the faster the cleaning agent remaining in the container body 100 is cleared, and the faster the container body 100 is dried.

[0099] It should be noted that the cleaning agent is not limited to a single agent but can also be a combination of multiple agents. For example, the cleaning agent can be a combination of an acidic cleaning agent (suitable for pickling) and deionized water. During cleaning, the acidic cleaning agent can be used first, followed by deionized water after a period of time. After cleaning is completed, a strong airflow is used to remove the remaining deionized water and promote rapid drying of the interior of the container body 100 to prevent the residual particles in the container body 100 from affecting the accuracy of the next leaching experiment. The combination of cleaning agents is not limited to this, and the type of cleaning agent and the cleaning sequence can be flexibly adjusted according to actual needs. This application does not impose any specific restrictions.

[0100] It should also be noted that when the drive shaft 500 is located at the third rotation dead center, the second flange 420 is separated from the first output port 121, and the first output port 121 is no longer blocked by the second flange 420. A gap exists between the inner end of the first output port 121 and the outer ring wall of the rotating ring 400, and the gap between the two ends of the first flange 410 and the third flange 120, which are close to each other, is connected to the first output port 121. In this way, since the ends of the first flange 410 and the third flange 120 are close to each other, the air between the two ends of the first flange 410 and the third flange 120 (such as Figure 8 After being squeezed, the air in area A can be blown out through the first output port 121, so that the residual leachate in the first output port 121 is fully blown into the leachate collecting device, thereby preventing the leachate from remaining in the first output port 121, thereby preventing the residual leachate from being mixed into the leachate of the next leaching experiment, and avoiding affecting the accuracy of the subsequent leaching experiments.

[0101] When the container body 100 is fully dried, the drive shaft 500 is driven back to the first rotation dead point to conduct the next leaching experiment.

[0102] The control of the driver, the control valves of the leaching agent input pipe, the cleaning agent input pipe and the air input pipe, and the corresponding leaching agent supply device, the cleaning agent supply device and the air supply device can all be uniformly controlled by the controller to realize the automatic conduct of the leaching experiment.

[0103] It can be understood that during the leaching experiment, the automated leaching experiment device can be placed in a hot chamber set at the required temperature according to actual needs, or the container body 100 of the automated leaching experiment device can be equipped with a temperature control component that can regulate the temperature of the leaching agent.

[0104] It should be noted that a pressure balance hole (not shown in the figure) can also be opened on the outer wall of the container body 100. The pressure balance hole extends from the outer wall of the container body 100 to the receiving groove 110. Figure 8The middle A area is connected, and the air pressure balance hole is set near the third flange 120. The air pressure balance hole is provided with a one-way valve. Under the action of the one-way valve, external air can enter the A area, and the air in the A area cannot leave through the air pressure balance hole.

[0105] In general, the automated leaching experiment device provided in this embodiment can realize automatic replacement of the leachate during the leaching experiment and automatic cleaning of the container body 100, thereby realizing automated operation of continuous leaching experiments, which not only improves operational efficiency, but also reduces the health and safety risks of manual contact with the leachate and the waste solid body 2000.

[0106] In this embodiment, the extension arm 510 and the drive shaft 500 are fixedly connected by a mating member 540. The mating member 540 is circular and coaxially fixed to the drive shaft 500, and fits into the clearance notch 131. The mating member 540 engages with the clearance notch 131 and rotates along the circumference of the drive shaft 500 to engage with the clearance notch 131, forming a rotational seal between the mating member 540 and the clearance notch 131. This design prevents liquid and gas in the container body 100 from entering the extension groove 130 through the clearance notch 131, thereby allowing the liquid level in the container body 100 to submerge the mating member 540. The distance between the mating member 540 and the bottom wall of the container body 100 can also be reduced, facilitating the mating member 540's transmission of the extension arm 510.

[0107] The extension arm 510 includes a first extension section 511 disposed along the height direction of the container body 100 and a second extension section 512 disposed radially along the drive shaft 500. The first extension section 511 is fixedly connected to the mating member 540, and the second extension section 512 is fixedly connected to the bottom end of the first extension section 511. The sliding sleeve 520 is slidably engaged with the second extension section 512.

[0108] In this embodiment, a groove wall of the accommodating groove 110 away from the top of the container body 100 and an inner bottom wall of the container body 100 are located in the same plane.

[0109] Further, please combine Figure 10 The inner bottom wall of the container body 100 is fixedly connected with a support column 320, and the waste basket 300 is installed on the top of the support column 320. Specifically, the support column 320 and the container body 100 are coaxially arranged.

[0110] The support column 320 is equipped with a partition 330. The partition 330 is circular and coaxial with the support column 320. The support column 320 passes through the partition 330. The partition 330 is located between the waste basket 300 and the bottom wall of the container body 100. The waste basket 300 and the bottom wall of the container body 100 are both spaced apart from the partition 330. The diameter of the partition 330 is smaller than the inner diameter of the container body 100.

[0111] The first extension section 511 of the extension arm 510 is disposed near the inner sidewall of the container body 100 and is spaced apart from the edge of the partition 330. The second extension section 512 of the extension arm 510 is located on a side of the partition 330 away from the waste basket 300 and is spaced apart from the partition 330.

[0112] Please combine Figure 11 The outer top wall of the container body 100 is provided with an annular flange 140, which is coaxially arranged with the support column 320. The end of the annular flange 140 away from the container body 100 is fixedly connected with a reference plate 141, and a fixing column 142 is fixedly connected between the reference plate 141 and the top wall of the container body 100. The fixing column 142 is coaxially arranged with the annular flange 140, and the outer diameter of the fixing column 142 is smaller than the inner diameter of the annular flange 140.

[0113] An annular moving member 150 is disposed within the annular flange 140. The moving member 150 is annular and is positioned around the fixed post 142. The outer edge of the moving member 150 abuts against the inner wall of the annular flange 140. The moving member 150 slides against the annular flange 140 along its axial direction. The moving member 150 is fixedly engaged with the annular flange 140 along its circumferential direction.

[0114] The moving member 150 is fixedly connected to a cylindrical mating tube 151. The outer diameter of the mating tube 151 is smaller than the inner diameter of the container body 100, and the inner diameter of the mating tube 151 matches the diameter of the partition 330. The top wall of the container body 100 is provided with an annular notch for the mating tube 151 to pass through. The notch is circular and fits snugly within the notch, creating a sliding seal. The notch effectively "cuts" a circular plate from the top wall of the container body 100, which is then fixedly connected to the fixing post 142.

[0115] In this embodiment, the moving member 150 is driven by a linear actuator (not shown).

[0116] The fitting cylinder 151 has a first movement stop point and a second movement stop point.

[0117] When the matching cylinder 151 is at the first movement stop point, the bottom end surface of the matching cylinder 151 and the inner top wall of the container body 100 are located in the same plane. Figure 11 shown.

[0118] When the mating tube 151 is at the second dead point, the bottom end surface of the mating tube 151 and the bottom surface of the partition 330 are in the same plane, and the inner side wall of the mating tube 151 and the outer side wall (outer edge) of the partition 330 are in contact and sealed. Figure 12 shown.

[0119] Under normal conditions, the coupling cylinder 151 is at the first rotational stop. When the drive shaft 500 is at the third rotational stop, after the cleaning agent has cleaned the container body 100 and the solidified waste body 2000 for a certain period of time, the leachate and particle residues on the surface of the solidified waste body 2000, the waste basket 300, the support column 320, and the partition 330 are essentially cleaned. At this point, the coupling cylinder 151 can be adjusted to the second rotational stop. This reduces the flow area within the container body 100 for the cleaning agent to circulate, thereby increasing the flow intensity of the cleaning agent and strengthening the cleaning agent's ability to clean the inner wall of the container body 100, thereby helping to shorten the cleaning time and reduce the amount of cleaning agent used. After the cleaning agent has finished cleaning the container body, the coupling cylinder 151 can be adjusted back to the first rotational stop.

[0120] In this embodiment, the opening of the container body 100 is located at the top thereof, and the opening of the container body 100 is detachably fitted with and sealed by the cover 160. The annular flange 140 is provided on the cover 160, and the annular notch is defined in the cover 160.

[0121] Furthermore, a first extension hole 210 is formed on a side wall of the receiving groove 110 close to the top of the container body 100 , and the first extension hole 210 extends to the top of the container body 100 .

[0122] Please combine Figure 13 and Figure 14 A rotating rod 211 rotatably engages within the first extension hole 210. The rotating rod 211 extends into the receiving slot 110, and a coaxially fixed engagement gear 212 is provided at the bottom end of the rotating rod 211. Along the axial direction of the first extension hole 210, the rotating rod 211 is fixedly engaged with the first extension hole 210; along the circumferential direction of the first extension hole 210, the rotating rod 211 rotatably engages with the first extension hole 210.

[0123] The first flange 410 is provided with a rack 413 extending along the circumference of the rotating ring 400, and the gear 212 is engaged with the rack 413. Optionally, the rack 413 is located in the sliding groove 411, and during the relative movement of the rotating ring 400 and the sliding member 412, the rack 413 and the sliding member 412 do not contact each other, but the present invention is not limited thereto.

[0124] The top end of the first extension hole 210 is coaxially fixedly connected to the second extension hole 220, which houses an extension sleeve 221. The extension sleeve 221 is fixedly engaged with the second extension hole 220 along the circumference of the second extension hole 220. The extension sleeve 221 is slidably engaged with the second extension hole 220 along the axial direction of the second extension hole 220. The rotating rod 211 has external threads, and the extension sleeve 221 has internal threads. The rotating rod 211 and the extension sleeve 221 are threadedly engaged. Rotating the rotating rod 211 drives the extension sleeve 221 axially within the second extension hole 220 via the threads.

[0125] The end of the second extension hole 220 away from the first extension hole 210 is connected to a receiving hole 230. The receiving hole 230 is arranged along the radial direction of the container body 100 and extends through the outer wall of the container body 100. A locking tongue 231 is fitted into the receiving hole 230. An elastic member 232 is connected between the inner end wall of the receiving hole 230 and the locking tongue 231. The elastic member 232 is used to apply tension to the locking tongue 231. In its natural state, the locking tongue 231 is completely retracted into the receiving hole 230 under the elastic force of the elastic member 232.

[0126] The cover 160 has a rim for being sleeved on the container body 100 , and a locking hole 161 for engaging with the receiving hole 230 is formed on the inner side wall of the rim.

[0127] A groove 233 is defined on the side of the locking tongue 231 that is closest to the extension sleeve 221. Along the axial direction of the receiving hole 230, the length of the groove 233 is greater than the diameter of the extension sleeve 221. The side of the groove 233 that is closest to the outer wall of the container body 100 is inclined, i.e., the side of the groove 233 that is closest to the outer wall of the container body 100 is wedge-shaped. This allows the extension sleeve 221 to extend into the groove 233, pushing the locking tongue 231 out of the receiving hole 230, thereby allowing the locking tongue 231 to be inserted into the locking hole 161.

[0128] When the driving shaft 500 is located at the first rotation dead center, the extension sleeve 221 pushes the locking tongue 231 into the locking hole 161, thereby locking the cover 160. Figure 13 shown.

[0129] When the driving shaft 500 is located at the third rotation stop point, the extension sleeve 221 retreats into the second extension hole 220, and the locking tongue 231 withdraws from the locking hole 161, thereby unlocking the cover 160. Figure 14 shown.

[0130] With this design, when a leaching experiment is being carried out in the container body 100 (when the leaching agent is soaking the solidified waste body 2000), the cover 160 is locked by the locking tongue 231, thereby preventing the cover 160 from being accidentally opened and affecting the accuracy of the leaching experiment.

[0131] When the drive shaft 500 is at the third rotational stop, the leachate in the container body 100 has been completely drained. Opening the cover 160 at this point will not affect the accuracy of the leaching experiment data. This ensures that the cover 160 can only be opened after the leaching process is complete and the leachate has been completely collected, preventing accidental interruptions to the leaching process.

[0132] Furthermore, a clearance opening 170 is formed on the outer wall of the container body 100 . The clearance opening 170 is communicated with the receiving groove 110 , and the matching rod 530 extends to the outside of the container body 100 through the clearance opening 170 .

[0133] A sleeve 430 is fixedly connected to the outer ring wall of the rotating ring 400 . The sleeve 430 is coaxially arranged with the matching rod 530 . The inner diameter of the sleeve 430 is larger than the outer diameter of the matching rod 530 .

[0134] The matching rod 530 is fixedly connected to a piston 550, and the piston 550 is slidably matched in the sleeve 430 and is slidably sealed with the sleeve 430. The end of the sleeve 430 away from the rotating ring 400 is an open structure.

[0135] The support column 320 defines an axial hole 321 extending through the inner bottom wall of the waste basket 300. A first push rod 322 is received at the top end of the axial hole 321. The first push rod 322 slidably engages with the axial hole 321 and forms a sliding seal therewith. A connecting pipe (not shown) connects the bottom end of the axial hole 321 to the end of the sleeve 430 closest to the rotating ring 400.

[0136] A second push rod 310 is fixedly connected to the inner top wall of the waste basket 300 . The second push rod 310 is coaxially spaced from the first push rod 322 .

[0137] With this design, the space inside the sleeve 430 located on the side of the piston 550 close to the rotating ring 400 is connected to the axial hole 321 of the support column 320 through a connecting tube. The top end of the axial hole 321 is closed by the first push rod 322 to form a closed structure. When the piston 550 moves relative to the sleeve 430, due to the change in air pressure in the closed structure, the first push rod 322 can retract into the axial hole 321 or extend from the axial hole 321.

[0138] The connecting pipe may extend from the inner ring wall of the rotating ring 400 to the bottom end of the support rod, and the connecting pipe may be made of a flexible material to adapt to the rotation of the rotating ring 400 .

[0139] When the driving shaft 500 is at the first rotation dead center, the piston 550 is located at the end of the sleeve 430 close to the rotating ring 400, and the first push rod 322 is pushed up, so that the solidified waste body 2000 is clamped and fixed by the first push rod 322 and the second push rod 310. Figure 15 At this point, the bottom end of the first push rod 322 is still located in the axial hole 321. In this state, typically during the leaching process of the leaching experiment, neither the top nor the bottom of the solidified waste body 2000 is in contact with the waste basket 300, which helps further increase the contact area between the solidified waste body 2000 and the leaching agent, thereby optimizing the leaching effect.

[0140] When the driving shaft 500 is located at the third rotation dead point, the piston 550 is located at the end of the sleeve 430 away from the rotating ring 400, and the first push rod 322 is retracted into the axial hole 321. Figure 10 In this state, the solidified waste body 2000 is not clamped and fixed, and has a certain amount of room to move in the waste basket 300. During the cleaning process, under the impact of the cleaning agent, the solidified waste body 2000 can sway with the flow of the cleaning agent in the waste basket 300. This helps to fully clean the surface of the solidified waste body 2000 and avoids the solidified waste body 2000 being clamped and fixed, resulting in the clamping position not being fully cleaned.

[0141] It should be noted that since the sleeve 430 extends out of the container body 100 through the clearance opening 170, the sleeve 430 will move within the range of the clearance opening 170 during operation. By observing the movement of the sleeve 430, it is possible to determine whether the driving process of the drive shaft 500 is smooth, and to assist in determining whether there is a mechanical failure.

[0142] In other embodiments of the present invention, instead of using the first push rod 322 and the second push rod 310 to clamp and fix the solidified waste body 2000, the solidified waste body 2000 can be placed in a mesh bag, and the mesh bag containing the solidified waste body 2000 is then hung in the waste basket 300. In this case, the waste basket 300 is used to limit the range of movement of the solidified waste body 2000, thereby preventing the mesh bag containing the solidified waste body 2000 from shaking significantly.

[0143] In some other embodiments of the present invention, the waste basket 300 may not be provided. Instead, the solidified waste body 2000 may be placed in a mesh bag, and the mesh bag containing the solidified waste body 2000 may be directly hung in the container body 100 .

[0144] It should be noted that the automated leaching experimental device can be applied to leaching tests of various waste solid bodies 2000. According to the type of waste solid body 2000, the type of corresponding leaching agent and cleaning agent can be selected in a targeted manner, and the material of each component in the automated leaching experimental device can also be selected in a targeted manner. This application does not impose any specific restrictions.

[0145] As an application example of the automated leaching test device, the automated leaching test device can be applied to, but is not limited to, leaching tests on radioactive waste solidified bodies 2000. The automated leaching test device can also be used for leaching tests on other types of waste solidified bodies 2000.

[0146] This embodiment also provides a radioactive waste solidified body 2000 leaching experimental system, which includes: the above-mentioned automated leaching experimental device. It is understood that the radioactive waste solidified body 2000 leaching experimental system also includes a hot chamber or temperature control component for controlling the leaching temperature.

[0147] To sum up, the automated leaching experiment device provided in the embodiment of the present invention can realize automatic replacement of the leachate during the leaching experiment and automatic cleaning of the container body 100, thereby realizing the automated operation of the continuous leaching experiment, which not only improves the operating efficiency, but also reduces the health and safety risks of manual contact with the leachate and the waste solid body 2000.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
