Problems solved by technology

[0003] 1) The remote operability of the special cap-opening tool for the sampling bottle and its carrier container is low, and it occupies a lot of space in the sampling cabinet, which affects the operation and use of the manipulator. The sample bottle carrier container is commonly known as running rabbit;
[0004] 2) The surface of the stainless steel sampling bottle is smooth, it is not easy to clamp, transfer and open the cap, and there is a hidden danger of spilling;
[0005] 3) The funnel opening of the auxiliary transfer equipment from the sampler to the sampling bottle is too small, which is easy to spill the material. The fixing tool for the sampling bottle under the funnel is poor in operability, which will easily cause the sampling bottle to fall and the phenomenon of material spilling, and the length of the sampler is short. The material surface cannot be reached, and the operation of the manipulator has been lifted to the height limit, so it is unrealistic to extend the length of the sampler
[0006] The above problems make it difficult to realize the operation of taking and sending samples of plutonium product powder

Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Such as figure 1 , figure 2 A movable plutonium powder sampling device shown includes a sampling platform 9 , sampling forceps, a funnel 3 , a sampling bottle 4 , and a running rabbit 11 .

[0042] The sampling platform 9 is located in the sampling cabinet and can move in the sampling cabinet. Sampling platform 9 adopts thickened metal material, to guarantee stability.

[0043] A sampling tongs placement cup 1 is provided on the sampling platform 9 for placing the sampling tongs. The described sampling tongs place the cup 1 and the sampling platform 9 are welded and fixed to increase the weight of the sampling platform 9 and further ensure stability.

[0044] Such as image 3 , Figure 4 As shown, the sampling pliers include a clamping handle 15, a connecting rod 16 and a jaw. The clamp handle 15 and the jaws are opened...

Abstract

The invention relates to the field of spent fuel aftertreatment and in particular discloses a moveable plutonium powder sampling device which comprises a sampling stage, wherein a sampling tongs holding cup, a funnel holding stand, a funnel holding cup, a sampling bottle fixing tank and a rabbit fixing tank are arranged on the sampling stage; a pair of sampling tongs are arranged in the sampling tongs holding cup; a funnel is arranged in the funnel holding cup; a rabbit is arranged in the rabbit fixing tank; a sampling bottle can be moved in the sampling bottle fixing tank and the rabbit fixing tank. The sampling device disclosed by the invention is simple in structure arrangement, small in floor space, convenient to operate and high in reliability, samples can be prevented from being splashed out in the transferring process, the sampling operation time can be shortened, and in addition, the radiation protection cost can be reduced.

Description

technical field [0001] The invention belongs to the field of spent fuel reprocessing, and in particular relates to a movable plutonium powder sampling device. Background technique [0002] Obtaining the content of metallic plutonium in plutonium product powder through sampling analysis is the basic link for nuclear material balance calculation and determination of nuclear material quantity data in reprocessing plants. The powder of plutonium products is highly radioactive, and it is necessary to use a robot to take samples from a long distance. The original plutonium product powder sampling device of the reprocessing pilot plant has the following defects: [0003] 1) The remote operability of the special cap-opening tool for the sampling bottle and its carrier container is low, and it occupies a lot of space in the sampling cabinet, which affects the operation and use of the manipulator. The sample bottle carrier container is commonly known as running rabbit; [0004] 2) T...
