Embodiment 1

[0036] A sort of 89 SrCl 2 Solution production devices, such as figure 1 and figure 2 As shown, it includes a target tube crushing and dissolving device 2 , a filter device 3 , an air extraction joint 4 , a filling bottle 5 , a delivery pipeline 6 , a packing device 7 and a water pump 10 .

[0037] Wherein, the target tube crushing and dissolving device 2 includes a base 13, a crushing groove 14 arranged on the base 13, and a breaking hammer 15 placed in the crushing groove 14, such as Figure 4 shown. One end of the delivery pipe 6 communicates with the liquid inlet of the filter device 3 , and the other end extends to the inner bottom of the tank 14 .

[0038]The filter device 3 is preferably composed of a sand core filter column and a 0.1 μm-10 μm microporous filter membrane arranged in the sand core filter column. The sub-bottling 5 can be a two-necked bottle or a three-necked bottle, preferably a two-necked bottle in the present embodiment. A solution outlet and a s...

Embodiment 2

[0044] The difference between this embodiment and Embodiment 1 is that this embodiment adds a target tube cleaning device 1 for target cleaning, such as image 3 As shown, the specific settings are as follows:

[0045] The target tube cleaning device 1 includes a washing tank 11 and a drain pipe 12, the bottom of the washing tank 11 is provided with a collecting tank for collecting the liquid after washing, and an inclined guide surface for the liquid to flow to the collecting tank after washing, and the draining The lower end of the pipe 12 extends into the collection tank. The upper end of the drain pipe 12 is connected with a waste liquid collecting device 8 .

[0046] Before the target is transferred to the target tube crushing and dissolving device 2, the target is first transferred to the target tube cleaning device 1, cleaned with nitric acid, deionized water, etc., and then the washing waste liquid is discharged into the waste liquid collection device 8. .

[0047] ...

Embodiment 3

[0049] The difference between this embodiment and Embodiment 1 or 2 is that this embodiment further optimizes the structure of the target tube crushing and dissolving device 2, such as Figure 4 As shown, the specific settings are as follows:

[0050] A funnel 16 is also arranged on the top of the crushing tank 14, and a baffle 17 is arranged in the funnel 16 to prevent debris and samples from splashing out during crushing. The target tube crushing and dissolving device 2 is also connected with a peristaltic pump 9 for inputting the solution for dissolving the powder in the target. Through the arrangement of the peristaltic pump 9, not only can effectively realize the continuous production of products, but also can effectively add cleaning solution to realize cleaning of the whole device of the present invention, and the operation is more convenient.

Abstract

The invention provides an 89SrCl2 solution production device, which solves the problem that the specific process of obtaining strontium carbonate powder obtained after irradiation from a target tube, dissolving, filtering and subpackaging to obtain a strontium chloride solution cannot achieve efficient and simple batch production . The target tube crushing and dissolving device (2) used for target crushing and powder dissolution in the target, the filter device (3) used for dissolving liquid filtration, the sub-packaging bottle (5) connected with the filter device (3), The suction joint (4) connected to the filter device (3) and the sub-bottling bottle (5), and the water pump (10) connected to the suction joint (4); the liquid inlet of the filter device (3) is delivered through The pipeline (6) is connected to the bottom end of the target tube crushing and dissolving device (2). The invention has the characteristics of fast operation, simplicity and high efficiency, convenient cleaning after the production is completed, waste liquid can be discharged immediately, and the risk of radioactive pollution is reduced. The invention also has the advantages of compact structure, simplicity and high efficiency, and is suitable for continuous production.

Description

technical field [0001] The invention belongs to the technical field of radioisotope preparation and relates to a 89 SrCl 2 Solution production device. Background technique [0002] 89 Sr is a β-radioactive nuclide with a physical half-life of 50.53d. It mainly emits β-rays when it decays. The maximum energy of β-rays is 0.586MeV (9.6×10 -3 %) and 1.495MeV (99.99%), average energy 0.56MeV, gamma ray energy 0.909MeV (9.6×10 -3 %), is an ideal therapeutic nuclide. strontium chloride [ 89 Sr] is mainly used for the relief of bone pain caused by bone metastasis of advanced malignant tumors such as prostate cancer and breast cancer. radiopharmaceuticals. At present, it has become a routine treatment item in many hospitals and has a good market prospect. [0003] Currently, 89 Sr has target neutron irradiation production and uranium fission product extraction and other preparation methods. Among them, there are two ways for target neutron irradiation production, namely, us...
