Description

Technical Field

[0001] The invention belongs to the technical field of lightly polluted material collection, and in particular relates to a sampler for APG waste resin in an evaporator sewage discharge system. Background Art

[0002] During the operation of nuclear power plants, some APG waste resins will be generated in the evaporator sewage system, which are usually temporarily stored in plastic barrels. In order to achieve the principle of minimizing radioactive waste, these APG waste resins need to be evaluated and deregulated, which requires sample collection.

[0003] The sampling of samples needs to be efficient and representative. At present, people use samplers to sample barreled waste resin, but the samplers currently used are made of stainless steel, which has a high specific gravity (7.70-8.00g / cm 3 ), its weight is heavy, and the staff have to conduct sampling with great intensity, which affects the staff's sampling efficiency; at the same time, the sampler is often stuck by resin during the sampling process, affecting its use. Summary of the invention

[0004] In view of the defects existing in the prior art, the purpose of the present invention is to provide a sampler for APG waste resin in the evaporator sewage discharge system. The sampler can be used to sample barreled resin at different positions and heights, so that the collected samples are representative; at the same time, the sampling efficiency is high, and the probability of the sampler being stuck due to resin during the sampling process can be greatly reduced.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0008] Furthermore, in the sampler for APG waste resin in the evaporator sewage discharge system as described above, the inner tube is a solid tube, and the side wall of the inner tube is provided with three feed cavities corresponding to the upper, middle and lower three feed ports.

[0009] Furthermore, in the sampler for APG waste resin in the evaporator drainage system as described above, the cross-sectional size of the feed cavity is smaller than the cross-sectional size of the feed port.

[0010] Furthermore, in the above-mentioned sampler for APG waste resin in the evaporator sewage discharge system, the top ends of the outer tube and the inner tube are both provided with T-shaped handles.

[0011] Furthermore, as described above, for the sampler for APG waste resin in the evaporator sewage discharge system, when the two T handles of the outer tube and the inner tube are in a parallel state, the feed port is in an open state to enable feeding; when the two T handles of the outer tube and the inner tube are in a vertical state, the feed port is in a closed state to stop feeding.

[0012] Furthermore, the sampler for APG waste resin in the evaporator sewage discharge system as described above is made of super-hard aluminum.

[0013] Furthermore, in the sampler for APG waste resin in the evaporator sewage discharge system as described above, the bottoms of the outer tube and the inner tube are both conical closed structures.

[0014] Furthermore, in the sampler for APG waste resin in the evaporator sewage discharge system as described above, the feed port and the feed chamber are both rectangular parallelepiped structures, and the corner connections thereof are arc-shaped.

[0015] Further, in the sampler for APG waste resin of the evaporator blowdown system as described above, the outer tube and the inner tube are connected by threads.

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Figure 1 A schematic structural diagram of a sampler for APG waste resin in an evaporator sewage discharge system provided in an embodiment of the present invention is shown, the sampler comprises an outer tube 1 and an inner tube 2, the inner tube 2 is coaxially sleeved inside the outer tube 1, and the two are tightly connected; a feed port 3 is provided on the side wall of the outer tube 1, and a feed cavity 4 corresponding to the feed port 3 is provided on the side wall of the inner tube 2.

[0025] See also Figure 2 As shown, the outer tube 1 is a hollow tube, and three feed ports 3, namely, upper, middle and lower, are provided on the side wall of the outer tube 1 for sampling different heights of barreled resin.

[0026] See also Figure 3 As shown, the inner tube 2 is a solid tube, and the side wall of the inner tube 2 is provided with three feeding cavities 4 corresponding to the upper, middle and lower feeding ports 3. The cross-sectional dimensions of the feeding cavities 4 are smaller than the cross-sectional dimensions of the feeding ports 3. Such a configuration can ensure smooth feeding of the sample, and at the same time can reduce the contact area between the outer tube 1 and the inner tube 2, thereby reducing friction resistance and facilitating sample collection.

[0027] For easy operation, the top of the outer tube 1 and the inner tube 2 are both provided with a T-shaped handle 5. When the two T-handles of the outer tube 1 and the inner tube 2 are in a parallel state, the positions of the upper, middle and lower three feed ports 3 and the three feed chambers 4 coincide, and the feed ports 3 are in an open state at this time, and feeding is achieved; when the two T-handles of the outer tube 1 and the inner tube 2 are in a vertical state, the positions of the upper, middle and lower three feed ports 3 and the three feed chambers 4 are vertical, and the feed ports 3 are in a closed state at this time, and feeding is stopped.

[0028] In a specific embodiment of the present invention, the sampler is made of super-hard aluminum, which has a small specific gravity, light weight, and low sampling intensity, thereby having a high sampling efficiency and reducing radiation damage to workers during the sampling process.

[0029] In a specific embodiment of the present invention, the bottoms of the outer tube 1 and the inner tube 2 are both conical closed structures, and the conical tip can reduce the resistance when the sampler is inserted into different depths and positions of barreled resin.

[0030] In a specific embodiment of the present invention, the feed port 3 and the feed cavity 4 are both rectangular parallelepiped structures, and the corner connections thereof are arc-shaped.

[0031] In a specific embodiment of the present invention, the outer tube 1 and the inner tube 2 are connected by threads.

[0032] The operation flow of using the sampler provided by the present invention to sample different heights of barreled resin is as follows:

[0033] S1. First, rotate the two T handles of the outer tube 1 and the inner tube 2 to a mutually perpendicular state, so that the positions of the feed port 3 and the feed cavity 4 are mutually perpendicular. At this time, the feed port 3 is in a closed state;

[0034] S2, then vertically insert the sampler into the barrel filled with APG waste resin to a set depth and a set position;

[0035] S3, then rotate the two T handles of the outer tube 1 and the inner tube 2 to be parallel to each other, so that the positions of the feed port 3 and the feed cavity 4 overlap, and the feed port 3 is in an open state at this time, and the resins at different depths at this position enter the corresponding feed cavity 4 from the three feed ports 3 respectively, so as to realize the sampling of samples at three depths;

[0036] S4, rotate the two T handles of the outer tube 1 and the inner tube 2 to a mutually perpendicular state, so that the positions of the feed port 3 and the feed cavity 4 are mutually perpendicular, and the feed port 3 is in a closed state at this time;

[0037] S5. Finally, lift the sampler vertically out of the barrel, open the feed port 3, and transfer the sample in the feed cavity 4 to the sample container;

[0038] S6. Repeat steps S1-S5, and vertically insert the sampler into the barrel at different depths and positions to achieve sample sampling at different depths and positions.

[0039] The sampler for APG waste resin in the evaporator sewage discharge system provided by the present invention adopts super-hard aluminum material with low density and high strength, which can reduce the sampling intensity of staff and speed up sampling efficiency; the sampler has a simple structural design and is easy to operate, and can collect samples from different positions and depths of barreled resin, thus meeting the representative requirements for barreled resin sampling; through structural optimization, the probability of the sampler being stuck due to resin is greatly reduced, thereby ensuring the continuity of the sampling work.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
