Description

Technical Field

[0001] This utility model relates to the field of scale sampling technology, specifically a boiler scale sampling device. Background Technology

[0002] Sampling spoons and shovels are suitable for small boilers or areas where scale is easily obtained. Operators can directly use these tools to scrape or scoop scale samples from visible parts of the boiler, such as manholes and handholes. This method is simple to operate, but it can only obtain surface and local scale samples, and the samples may not be representative due to human operation.

[0003] Manual sampling is usually limited to visible areas such as manholes and handholes in boilers, making it difficult to reach complex, narrow, or hidden areas inside the boiler. These areas may contain different types and degrees of scale, leading to incomplete sampling. At the same time, the internal temperature of the boiler is high during operation, and it takes a certain amount of time to cool down even after shutdown. If manual sampling is performed before sufficient cooling, operators may come into contact with high-temperature components or be scalded by steam. Therefore, we have proposed a boiler scale sampling device. Utility Model Content

These areas may have different types and degrees of scale, resulting in incomplete sampling. At the same time, the internal temperature of the boiler is high when it is running, and it needs a certain amount of time to cool down even after the boiler is shut down. If manual sampling is carried out before it has cooled down sufficiently, the operator may come into contact with high-temperature parts or be scalded by steam. To achieve the above objectives, this utility model provides the following technical solution: a boiler scale sampling device, comprising a fixed outer shell, a protective inner shell fixedly connected inside the fixed outer shell, a sampling component disposed inside the protective inner shell, the sampling component comprising a movable rod, the movable rod being movably connected inside the protective inner shell, an elbow hook fixedly connected to the top end of the movable rod, a fixing plate one movably connected to the side surface of the movable rod, a limit spring fixedly connected to the bottom end of the fixing plate one, a fixing plate two fixedly connected to the bottom end of the limit spring, the fixing plate two fixedly connected to the side surface of the movable rod, an annular sleeve fixedly connected to the bottom end of the movable rod, a connecting piece fixedly connected to the bottom of the annular sleeve, and the connecting piece...

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 This utility model provides a technical solution: a boiler scale sampling device, including a fixed outer shell 1, a protective inner shell 3 fixedly connected inside the fixed outer shell 1, a sampling component 5 disposed inside the protective inner shell 3, the sampling component 5 including a movable rod 501, the movable rod 501 being movably connected inside the protective inner shell 3, an elbow hook 502 fixedly connected to the top end of the movable rod 501, a fixing plate 503 movably connected to the side surface of the movable rod 501, and a limit spring 504 fixedly connected to the bottom end of the fixing plate 503. A fixing plate 505 is fixedly connected to the bottom end of the movable rod 501. The fixing plate 505 is fixedly connected to the side surface of the movable rod 501. An annular sleeve 506 is fixedly connected to the bottom end of the movable rod 501. A connecting piece 507 is fixedly connected to the bottom of the annular sleeve 506. Two fixing springs 508 are fixedly connected to one side of the connecting piece 507. The two fixing springs 508 are symmetrically distributed on one side of the connecting piece 507. A movable scraper 509 is fixedly connected to the other end of the two fixing springs 508. The connecting piece 507 and the movable scraper 509 are fixedly connected. The device includes a sample collection box 510. Users insert the device into the boiler using the handle 8 to collect scale samples. Pushing the movable rod 501 connects the movable scraper 509 of the sampling component 5 to the scale area. Simultaneously, as the movable rod 501 is pushed, the limiting spring 504 is pulled downwards by the fixing plate 505. Upon reaching the sampling area, releasing the movable rod 501 causes it to be pulled back by the limiting spring 504, scraping away the scale. The scale sample falls into the sample collection box 510 for collection. This allows for sampling operations to be completed quickly, significantly improving efficiency compared to traditional manual sampling methods. It enables rapid acquisition of boiler scale samples, meeting the needs for timely boiler detection and analysis. This facilitates timely problem detection and appropriate measures, avoiding the need for operators to manually sample inside dangerous areas like the boiler. It also reduces safety risks such as burns, suffocation, and compression caused by high temperatures, high pressures, and confined spaces, ensuring the safety of operators.

[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a limiting cover 2 is fixedly connected to the top of the fixed outer shell 1. A through hole 201 is opened inside the limiting cover 2. A movable rod 501 is movably connected inside the through hole 201. A fixed plate 503 is fixedly connected to the top inner wall of the limiting cover 2. A protective sleeve 4 is fixedly connected to the side surface of the protective inner shell 3. A connecting plate 6 is fixedly connected to the bottom of the limiting cover 2.

[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a connecting block 7 is fixedly connected to the bottom of the connecting plate 6, one side of the connecting block 7 is fixedly connected to the side surface of the protective sleeve 4, a handle 8 is fixedly connected to one side of the connecting plate 6, and four fixing pads 9 are fixedly connected to the bottom of the protective sleeve 4. The four fixing pads 9 are symmetrically distributed at the bottom of the protective sleeve 4.

[0024] The usage method and advantages of this utility model: The boiler scale sampling device operates as follows:

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when using this boiler scale sampling device, the user inserts the device into the boiler by holding the handle 8 to sample the scale. By pushing the movable rod 501, the movable scraper 509 of the sampling component 5 connects to the scale. Simultaneously, as the movable rod 501 is pushed, the limiting spring 504 is pulled downward by the tension of the fixed plate 505. After reaching the sampling area, the movable rod 501 is released, causing the movable rod 501 to be pulled by the force of the limiting spring 504. This causes the movable scraper 509 to be pulled back, scraping away the scale. The scale sample falls into the sample box 510 for collection. The sampling operation can be completed in a short time, which greatly improves the sampling efficiency compared to the traditional manual sampling method. It can quickly obtain boiler scale samples, meet the needs of timely boiler detection and analysis, help to detect problems in time and take corresponding measures, and avoid the situation where operators enter dangerous areas such as the boiler interior for manual sampling. This reduces the safety risks of burns, suffocation, and crushing caused by factors such as high temperature, high pressure, and confined space, and ensures the personal safety of operators.
