[0037] Reference Figures 1 to 5, is a radioactive wet material compression device in some embodiments of the utility model, which includes a frame 1, a accommodating tube 2, a bearing plate 3, a lifting mechanism 4 and a pressing mechanism 5. The accommodating tube 2 is placed on the bearing plate 3, and the lifting mechanism 4 is arranged on the frame 1. The lifting mechanism 4 is used to drive the accommodating tube 2 to move up and down, so that the accommodating tube 2 can contact or separate from the bearing plate 3. The bearing plate 3 is used to support the radioactive wet material. A plurality of water leakage holes 32 are opened on the bearing plate 3. The pressing mechanism 5 is arranged on the frame 1. The pressing mechanism 5 is used to be inserted downward into the accommodating tube 2 to compress the radioactive wet material downward.

[0038] As can be seen from the above, when it is necessary to compress the radioactive wet material, the accommodating tube 2 is placed on the bearing plate 3, the radioactive wet material is filled into the accommodating tube 2, and the bearing plate 3 supports the radioactive wet material upward. After the radioactive wet material in the accommodating tube 2 is added, the pressing mechanism 5 is inserted downward into the accommodating tube 2 to compress the radioactive wet material in the accommodating tube 2 downward. During the pressing period of the pressing mechanism 5, the water in the radioactive wet material flows out from the leaking hole 32 on the bearing plate 3. After the pressing is completed, the pressing mechanism 5 can be reset, and the lifting mechanism 4 drives the accommodating tube 2 to move upward, so that the compressed block formed by the compressed radioactive wet material appears on the bearing plate 3, and the operator can transfer the compressed block away. Afterwards, the lifting mechanism 4 can be used to move downward to place the accommodating tube 2 on the bearing plate 3 again, so as to compress the radioactive wet material next time, and the operation is very convenient.

[0039] When the compressed radioactive wet matter sticks to the inner wall of the accommodating tube 2, the accommodating tube 2 is lifted by the lifting mechanism 4, and the pressing mechanism 5 can be inserted into the accommodating tube 2 to make the radioactive wet matter stuck to the inner wall of the accommodating tube 2 fall off the inner wall of the accommodating tube 2.

[0040] In order to facilitate the filling of radioactive wet objects and the removal of compressed radioactive wet objects, in some embodiments, the frame 1 includes a gantry 11 and a base 12, a slide rail 121 is provided on the base 12, the gantry 11 is fixed on the base 12, the bearing plate 3 is provided on the slide rail 121, the bearing plate 3 and the slide rail 121 can slide relative to each other, and the pressing mechanism 5 and the lifting mechanism 4 are respectively on the gantry 11. Before the radioactive wet objects are filled into the receiving tube 2, the receiving tube 2 is placed on the bearing plate 3, and the bearing plate 3 slides along the slide rail 121 outside the gantry 11 to prevent the gantry 11 from interfering with the addition of radioactive wet objects. When the addition is completed, the bearing plate 3 slides to the bottom of the gantry 11, so that the pressing mechanism 5 is aligned with the receiving tube 2. When the pressing mechanism 5 is pressed down, the lifting mechanism 4 lifts the receiving tube 2, so that the compressed radioactive wet objects are placed on the bearing plate 3. Then, the carrier plate 3 is moved to the outside of the gantry 11 to remove the compressed radioactive wet objects on the carrier plate 3 to prevent the container 2 from interfering with the transfer of the compressed radioactive wet objects. After the radioactive wet objects are removed, the carrier plate 3 is moved to the bottom of the container 2 again, and the container 2 is lowered onto the carrier plate 3 by the lifting mechanism 4. When the radioactive wet objects need to be compressed again, the carrier plate 3 together with the container 2 on the carrier plate 3 are moved along the slide rail 121 to the outside of the gantry 11.

[0041] In order to collect the water flowing out of the radioactive wet material conveniently, in some embodiments, two slide rails 121 are provided, the gantry 11 spans the two slide rails 121, a first groove 120 is provided on the base 12, and the first groove 120 is provided between the two slide rails 121. The radioactive wet material compression device further comprises a collection box 6, the collection box 6 is provided in the first groove 120, and the collection box 6 is used to collect the waste liquid dripping from the water leakage hole 32. When in use, the waste liquid dripping on the carrying plate 3 is collected by the collection box 6. Of course, the operator can also adjust the position of the collection box 6 according to the position of the carrying plate 3.

[0042] In order to facilitate the up and down movement of the accommodating cylinder 2, in some embodiments, a handle 23 fixedly connected to the side of the accommodating cylinder 2 is provided on the side of the accommodating cylinder 2, and the lifting mechanism 4 includes a cylinder 41 and a spring block. The cylinder 41 is fixed on the frame 1, and the cylinder 41 drives the spring block to reciprocate in the up and down directions. When the spring block moves downward until it abuts against the handle 23, it is compressed and avoids the handle 23. When the spring block moves upward, the spring block abuts against the handle 23 and can lift the accommodating cylinder 2 under the action of the cylinder 41. When it is necessary to lift the accommodating cylinder 2, the cylinder 41 drives the spring block to move downward. When the spring block touches the upper side of the handle 23, the cylinder 41 continues to provide a force for the spring block to move downward, so that the spring block overcomes the spring force and shrinks to avoid the handle 23 until the spring block is located below the handle 23. Then, the cylinder 41 drives the spring block to move upward, and the spring block abuts against the lower side of the handle 23 upward, and drives the handle 23 and the accommodating cylinder 2 to move upward together.

[0043] Preferably, two cylinders 41 are provided, two spring blocks are provided, and two handles 23 are provided. The spring blocks and the cylinders 41 are provided in a one-to-one correspondence, and the spring blocks and the handles 23 are provided in a one-to-one correspondence.

[0044] In order to achieve that the spring block can retract to avoid the handle 23 when it moves downward to touch the handle 23, and when the spring block moves upward, it can move upward against the bottom surface of the handle 23, in some embodiments, such as Figure 5 As shown, the spring clamping block includes a mounting block 421, a clamping block 422 and a spring body 423. The mounting block 421 is provided with a blind hole arranged horizontally, and the spring body 423 is arranged in the blind hole. The two ends of the spring body 423 are respectively connected to the clamping block 422 and the bottom surface of the blind hole. The lower side of the clamping block 422 facing away from the spring body 423 is provided with a chamfer, and the chamfer is used to abut against the handle 23. The structure is simple and convenient to set. The blind hole extends horizontally, and the expansion direction of the spring body 423 also extends along the depth direction of the blind hole. When the cylinder 41 drives the mounting block 421 to move downward, the chamfer on the clamping block 422 first contacts the handle 23. Through the setting of the chamfer, the clamping block 422 is subjected to the horizontal component of the handle 23 to compress the spring body 423 and the longitudinal component of the vertical force. In this way, the clamping block 422 can move deep into the blind hole to avoid the handle 23. After the clamping block 422 passes downwardly through the handle 23, the clamping block 422 moves toward the opening of the blind hole under the action of the force of the spring body 423 and extends out of the blind hole, and the cylinder 41 drives the mounting block 421 to move upward, so that the upper side surface of the clamping block 422 abuts against the bottom surface of the handle 23, thereby driving the handle 23 and the accommodating tube 2 to move upward.

[0045] In addition, in order to realize the up and down movement of the accommodating cylinder 2 driven by the lifting mechanism 4, other embodiments can also be adopted. For example, the side of the accommodating cylinder 2 is provided with a handle 23 fixedly connected to the side of the accommodating cylinder 2, and the lifting mechanism 4 includes an electric screw 431 and a lifting block 432. The electric screw 431 is arranged on the frame 1, and the electric screw 431 drives the lifting block 432 to move up and down. The handle 23 is arranged in the space where the lifting block 432 moves in the up and down direction. The lifting block 432 can lift the handle 23 upward under the action of the electric screw 431.

[0046] In some embodiments, the handle 23 is disposed on the outer cylinder 22 .

[0047] In order to fully drain the wastewater during the compression of the radioactive wet material, in some embodiments, the accommodating cylinder 2 includes an inner cylinder 21 and an outer cylinder 22 both arranged vertically, the inner cylinder 21 is arranged inside the outer cylinder 22, a plurality of water flow holes penetrating the side of the inner cylinder 21 are provided on the side wall of the inner cylinder 21, a gap is left between the inner cylinder 21 and the outer cylinder 22, the water flow holes and the gap are interconnected, and the inner cylinder 21 and the outer cylinder 22 are fixedly connected. When in use, the wastewater of the radioactive wet material compressed in the inner cylinder 21 can pass through the gap between the inner cylinder 21 and the outer cylinder 22 in the flow channel of the water flow holes. Under the action of gravity, the wastewater in the gap flows downward onto the bearing plate 3, and then the wastewater is drained downward through the water leakage holes 32 on the bearing plate 3. Through the arrangement of the outer cylinder 22, the outer cylinder 22 can block the wastewater flowing out of the water flow holes to prevent the wastewater flowing out of the water flow holes from splashing to the outside.

[0048] In order to prevent the radioactive wet material from blocking the water flow hole during the compression process, in some embodiments, the water flow hole includes a straight hole 211 and a tapered hole 212 that are interconnected, the straight hole 211 is arranged close to the inner wall of the inner cylinder 21, the tapered hole 212 is arranged close to the outer wall of the inner cylinder 21, and the cross-sectional area of ​​the tapered hole 212 gradually increases along the inner wall of the inner cylinder 21 toward the outer wall of the inner cylinder 21. More specifically, the end face of the tapered hole 212 with a larger inner diameter is located on the outer wall of the inner cylinder 21, and the tapered hole 212 and the straight hole 211 are interconnected to form a water flow hole. The structure is simple and convenient to set up.

[0049] In order to facilitate the positioning of the accommodating cylinder 2, in some embodiments, a second groove 31 is provided on the top surface of the carrying plate 3, and the second groove 31 is arranged in an annular shape. The accommodating cylinder 2 can be inserted into the second groove 31, and a water leakage hole 32 is provided in the inner bottom surface of the second groove 31 and / or the area surrounded by the second groove 31. When in use, the accommodating cylinder 2 is inserted into the second groove 31, and the accommodating cylinder 2 is limited by the second groove 31.

[0050] In some embodiments, both the inner cylinder 21 and the outer cylinder 22 can be simultaneously inserted into the second groove 31. Wastewater in the gap between the inner cylinder 21 and the outer cylinder 22 can flow directly downward into the second groove 31.

[0051] The pressing mechanism 5 is used to press down the radioactive wet objects so that the radioactive wet objects are compressed. In some embodiments, the pressing mechanism 5 includes a hydraulic cylinder 51 and a pressing block 52, wherein the fixed portion of the hydraulic cylinder 51 is fixed to the frame 1, and the pressing block 52 is disposed on the movable portion of the hydraulic cylinder 51, and the movable portion of the hydraulic cylinder 51 drives the pressing block 52 to move up and down, and the pressing block 52 and the inner diameter of the containing tube 2 are mutually adapted, and the pressing block 52 is used to press down the radioactive wet objects in the containing tube 2 and the carrier plate 3.
