Description

Technical Field

[0001] The utility model belongs to the field of radioactive chemical nondestructive analysis, and in particular relates to a sample bottle for mixed absorption boundary analysis. Background Art

[0002] Since the 1960s, research on nuclear material NDA methods and equipment has become one of the most active research areas in nuclear safety assurance and nuclear material management. Since the 1980s, hybrid absorbing boundary measurement technology (a non-destructive analysis method (NDA)) has been an important measurement method for nuclear material balance in the field of nuclear safeguards, mainly used for the precise measurement of U and Pu element concentrations in special nuclear materials in the spent fuel reprocessing process.

[0003] The hybrid absorption boundary measurement device does not require sample pretreatment and directly monitors the concentration of U and Pu in the first-end solution and initial feed (1AF) solution, process products and products generated during the spent fuel reprocessing process. The hybrid absorption boundary measurement device improves the timeliness and effectiveness of sample analysis, and provides a reliable basis for process control and U and Pu material balance. It provides key data for process operation and guides the adjustment of solution acidity and plutonium valence.

[0004] During the measurement process, the hybrid absorption boundary measurement device needs to use a robotic arm to drip the sample solution into the sample pool in the radiation shielding box, and then seal the sample bottle and put it into the device for detection. During the measurement, operations such as opening / closing the sample bottle, removing and recovering the sample solution are all manually controlled by a robotic arm. The existing sample bottle consists of a bottle cap, two independent sample pools, a sample pool tray and a positioning tray. It has many parts and a complex overall structure, which leads to complicated operation steps and long operation time when loading and recovering the sample solution; the two independent sample pools and the sample pool positioning tray require multiple robot end operations, and the two separate independent sample pools have small bottle mouths. When adding or recovering the sample solution, the robot arm operation accuracy requirements are high, the operation steps are many, and it is easy to drip, which increases the radiation risk of the operator; the existing sample bottle is relatively expensive, and the cost of using it as a disposable tool is high.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the detailed description of the embodiment of the utility model provided below is not intended to limit the scope of the utility model claimed for protection, but only represents the selected embodiment of the utility model.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0032] Embodiment 1:

[0033] like Figure 1 As shown, a sample bottle for hybrid absorption boundary analysis. It includes a bottle body 2 and a bottle cap 1 located above the bottle body 2 for sealing. The bottle body 2 includes a cylindrical bottle mouth 201 at the top, a sample pool in the middle, and a positioning hole 5 at the bottom. A connecting surface 202 is provided at the bottom of the bottle mouth 201 to connect to the upper opening of the sample pool. The bottle mouth 201 cooperates with the side surface 101 of the bottle cap 1 to install the bottle cap 1. The sample pool is a wide rectangular parallelepiped sample pool 203 and a thin truncated cone sample pool 204 arranged in parallel. The two sample pools are connected. The axis of the thin truncated cone sample pool 204 is located on the symmetric plane of the long side of the square sample pool. The narrow connecting channel 6 is perpendicular to the wall of the wide rectangular parallelepiped sample pool 203. The wide rectangular sample pool 203 is arranged in the center, and the two opposite narrow sides are used as the detection surface 3. The wall thickness of the detection surface 3 is thinned to form a chamfered rectangular step width on the bottle body 2. The rectangular step is designed to control the shrinkage rate, so that the spacing between the detection surfaces 3 is fixed, the wall thickness is consistent, and the sample pool has good consistency to avoid affecting the detection results. The outer side of the wide rectangular sample pool 203 is the reference surface 4, and the reference surface 4 is used for positioning the bottle body 2 installed in the equipment. A positioning hole 5 is set at the bottom of the bottle body 2. The positioning hole 5 is used for clamping and positioning the outer wide side of the rectangular sample pool when the robot arm takes the cover as the reference surface 4. This sample bottle can be used for various tests, such as L boundary analysis, K boundary analysis, etc., and is particularly suitable for K boundary analysis.

[0034] The lower ends of the wide rectangular sample pool 203 and the thin truncated cone sample pool 204 are flush and have the same height, and are connected by a narrow connecting channel 6. The upper end of the narrow connecting channel 6 is flush with the sample pool, and the lower end is located on the upper part of the positioning hole 5 to reduce the amount of sample solution used. The larger end of the truncated cone sample pool faces upward, which can facilitate dripping and also reduce the amount of sample solution used.

[0035] The wall thickness of the outer wall of the wide rectangular parallelepiped sample pool 203 is consistent, which can achieve good processing control and meet the wall thickness requirements for use.

[0036] The upper part of the bottle body 2 is a circular convex cylindrical bottle mouth 201, and the bottle mouth 201 completely covers the middle sample pool area. The middle part of the bottle body 2 is a combination of arc and square. A thin frustum-shaped sample pool 204 is arranged in the arc side of the bottle body 2, and the outer periphery of the thin frustum-shaped sample pool 204 is hollowed out. The square side of the bottle body 2 is the pool wall of the wide rectangular parallelepiped sample pool 203. The two smaller opposite surfaces of the pool wall are the detection surface 3, and the larger surface is the reference surface 4. The surface opposite to the reference surface 4 is the surface that is not exposed to the outside and plays a connecting role.

[0037] The space between the wide rectangular sample pool 203 and the thin frustum-shaped sample pool 204 is set as a hollow structure from the bottom opening of the bottle body 2, which can reduce weight, reduce material consumption and sample solution usage, and control the overall shrinkage rate of the bottle body 2. The hollow structure also controls the wall thickness of the surface of the sample pool that is not directly exposed to the outside, so that the size of the sample pool meets the use requirements after processing.

[0038] The positioning hole 5 is located between the wide rectangular sample pool 203 and the thin truncated cone sample pool 204 and is arranged parallel to the wall of the wide rectangular sample pool 203. The positioning hole 5 is located in the arc region and passes through the lower part of the narrow connecting channel 6. The positioning hole 5 at the bottom of the bottle body 2 is a three-hole one-line structure. The positioning hole 5 is located in the arc region of the bottle body 2 and passes through the bottom of the narrow connecting channel 6. The positioning hole 5 is used for clamping and positioning of the robot arm.

[0039] The bottle cap 1 includes a side 101, a top 102 and a handle 103. The side 101 cooperates with the convex cylindrical bottle mouth 201 of the bottle body 2 to achieve extrusion sealing. The edge of the top 102 extends to form an edge that is buckled on the bottle mouth 201. This structure can prevent the sample solution from dripping and overflowing after the bottle cap 1 is covered. The handle 103 is located at the center of the upper surface of the top 102 and is used to clamp the bottle cap 1.

[0040] A raised sealing ring 1011 is provided on the circumferential outer surface of the annular side surface 101, and the sealing ring 1011 increases the sealing effect. This embodiment adopts a plurality of parallel sealing rings 1011, and the sealing ring 1011 has a better effect when a plurality of parallel rings are used.

[0041] The height of the convex cylindrical bottle mouth 201 is greater than the height of the side of the bottle cap 1 matched therewith, and the inner wall surface of the convex cylindrical bottle mouth 201 and the outer side surface of the bottle cap 1 are matching surfaces, that is, the lower end of the bottle cap 1 does not contact the connecting surface 202 of the bottle body 2, preventing the bottle cap 1 from directly contacting the sample solution.

[0042] The bottle cap 1 and the bottle body 2 are integrally formed of PP material. A process hole 104 for controlling the shrinkage rate is designed on the bottle cap 1, which can simplify the manufacturing process and meet the specification standards.
