Description

Technical Field

[0001] This utility model relates to the field of slurry concentration measurement technology, and in particular to a radiation source shielding device. Background Technology

[0002] In industrial production, some equipment uses radioactive sources for measurement and other operations. For example, Baoshan Mining Company uses a nuclear concentration meter to measure the concentration of mineral slurry. This type of nuclear concentration meter uses radioactive material sintered into a waterproof ceramic core, which is then sealed with a double-layered stainless steel shell. The shell is further covered with a thick layer of lead for radiation shielding. A rotating body with a collimation aperture is installed on the lead shield. During operation, radiation is directed through the beam aperture into the pipe containing the mineral slurry and reaches the detector.

[0003] However, during this work process, there are still instances where a small amount of radiation escapes from the lead container and is exposed to the air. Due to the nature of the job, the torso and head of the workers inevitably enter the area of ​​radiation exposure, which has adverse effects on their health and may lead to various health problems in the long term. It also causes workers to have a fear of radiation sources, affecting their work efficiency. Utility Model Content

[0022] The purpose of this invention is to provide a radiation source shielding device to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively protects the health of workers, and effectively improves work efficiency.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a radiation source shielding device 100, such as... Figures 1-3As shown, the device includes: a first support member, a second support member, a fixing plate 3, and a radiation shielding member 4. The first support member has a first end and a second end arranged opposite to each other, and the second support member has a third end and a fourth end arranged opposite to each other. The first end and the third end are detachably fixedly connected to be fitted and fixed onto the receiver 8 of the nuclear concentration meter. The fixing plate 3 is fixedly connected to the second end and the fourth end and is located in the direction away from the measuring pipe of the receiver 8. The radiation shielding member 4 is fixedly connected to the fixing plate 3 and is located between the fixing plate 3 and the receiver 8. The detachable fixed connection method allows the radiation source shielding device 100 to be easily and quickly installed on the receiver 8 of the nuclear concentration meter. When equipment maintenance, inspection, or replacement of parts is required, the device can be easily removed from the receiver 8, improving the convenience of equipment maintenance and reducing maintenance costs and time. Moreover, this connection method can be adjusted and adapted according to the actual size of the receiver 8, enhancing the versatility and applicability of the device. The fixing plate 3 is positioned away from the measuring pipe from the receiver 8. This provides stable support for the radiation shield 4, ensuring its stability and positional accuracy during operation. Furthermore, its rational placement enhances the overall layout of the device, facilitating better shielding of the radiation shield 4, reducing the impact of the measuring pipe and other equipment on the shielding system, and allowing for easier operation around the receiver 8. The radiation shield 4, located between the fixing plate 3 and the receiver 8, directly shields against radiation that may be scattered around the receiver 8, effectively preventing the radiation emitted by the radiation source 7 from spreading into the surrounding environment. This minimizes radiation hazards to personnel and equipment, improving equipment and environmental safety.

[0025] In a preferred embodiment, the radiation shield 4 is a lead plate. Lead plates have good radiation shielding performance. Using lead plates as radiation shield 4 can efficiently absorb and block the radiation emitted by the radiation source 7, significantly reduce the amount of radiation leakage, better protect the health of people in the radiation area, and ensure that the surrounding environment meets safety standards.

[0026] In a preferred embodiment, the lead plate is an arc-shaped plate with its opening facing the receiver 8. This specific arc-shaped structure allows for a better fit to the shape of the receiver 8, increasing the spatial adaptability between the radiation shield 4 and the receiver 8, and expanding the radiation shielding range. The opening facing the receiver 8 can more effectively capture and shield radiation scattered from around the receiver 8, reducing the possibility of radiation leakage from the sides and edges, and further improving radiation shielding efficiency.

[0027] In a preferred embodiment, the curved plate has an arc side length of 450mm and a straight side length of 400mm. This precise dimensional design ensures a precise fit between the curved plate's structure and the receiver 8, as well as other components of the entire shielding device. Suitable side lengths meet the radiation shielding requirements of a specific type of nuclear concentration meter, ensuring optimal spatial layout and radiation shielding effect when working with the receiver 8 and other components, avoiding installation difficulties or insufficient shielding caused by unsuitable dimensions.

[0028] In a preferred embodiment, the fixing plate 3 is a steel plate, which has high strength and stability. As a fixing plate, the fixing plate 3 can provide a solid support foundation for the radiation shielding component 4, ensuring that the radiation shielding component 4 is not displaced or deformed by external forces during the operation of the device, ensuring the continuous and effective performance of the radiation shielding function, and making the overall structure of the device more stable and reliable.

[0029] In a preferred embodiment, the steel plate is a square with a side length of 350mm. This square design ensures better symmetry and consistency when the steel plate is connected to the first support, the second support, and the radiation shield 4. The standardized dimensions facilitate design, manufacturing, and installation, improving production efficiency and product quality, while also ensuring the regularity and stability of the entire device structure.

[0030] In a preferred embodiment, the radiation source shielding device 100 further includes multiple bolts and nuts.

This bolt and nut fixing method is simple and reliable, achieving a secure connection between the arc-shaped plate and the steel plate. Installation and disassembly are convenient and quick, requiring no complex tools or techniques from workers, thus improving the efficiency of equipment installation and maintenance. Furthermore, the tightness of the bolts and nuts allows for fine-tuning of the connection stability, ensuring the reliability of the entire device under different operating conditions.

[0031] In a preferred embodiment, the first support member includes a first half-clamp 5 and a first channel steel 1. One end of the first channel steel 1 is welded and fixed to a steel plate, and the other end is fixedly connected to the first half-clamp 5. The second support member includes a second half-clamp and a second channel steel 2. The second channel steel 2 is arranged parallel to the first channel steel 1, and one end of the second channel steel 2 is fixedly connected to the steel plate, while the other end is fixedly connected to the second half-clamp. The first half-clamp 5 and the second half-clamp are detachably fixedly connected to be sleeved and fixed on the receiver 8. This support member structure composed of half-clamps and channel steels ensures good connection stability with the receiver 8 and provides greater installation flexibility. The channel steel enhances the strength and rigidity of the support member, enabling it to withstand certain external forces without deformation while being fixed to the device. The detachable fixed connection between the first half-clamp 5 and the second half-clamp can accommodate receivers 8 with different outer diameters and allows for quick assembly and disassembly during equipment installation and maintenance, improving work efficiency.

[0032] During the usage phase, after the radiation source shielding device 100 is installed and checked for errors, the nuclear concentration meter and other related equipment are started to operate normally to measure the slurry concentration in the slurry pipeline 6. At this time, the device will function together with the equipment to shield the radiation generated by the radiation source 7 of the nuclear concentration meter.

[0033] On-site monitoring and inspection: During equipment operation, conduct regular on-site monitoring and inspection of the device. Observe for any abnormalities, such as loose parts or wear, and ensure that the radiation shielding component 4 (arc-shaped lead plate) always maintains the correct positional relationship with the receiver 8 and the fixing plate 3 to achieve good radiation shielding effect.

[0034] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model.
