Description

Technical Field

[0001] The utility model belongs to auxiliary training equipment for safe production of blast furnaces, in particular to a training device for judging the leakage state of a water supply pipeline. Background Art

[0002] In the blast furnace smelting industry, the cooling water pipe at the blast furnace tuyere is one of the key components to ensure the normal operation of the blast furnace. Due to the extremely high temperature inside the blast furnace, the cooling water pipe needs to continuously cool the tuyere to prevent the tuyere from being damaged by overheating. However, under long-term high temperature conditions, the cooling water pipe may be worn, aged or corroded, and have sand holes, leading to water leakage. Water leakage will not only affect the normal operation of the blast furnace, but may also damage the equipment and even cause safety accidents.

[0003] Therefore, regular inspections of cooling water pipes at the tuyere of the blast furnace and timely detection and treatment of water leakage are important measures to ensure the safe and stable operation of the blast furnace. However, in the actual production process, due to the differences in workers' skill levels and judgment abilities, misjudgments and miscalculations often occur, resulting in water leakage problems not being promptly and effectively handled, thus causing unnecessary losses to production.

[0004] At present, although there are some traditional detection methods, such as visual inspection and audio detection, these methods often rely on the experience and skill level of employees, the judgment results are easily affected by subjective factors, and the efficiency is low. In addition, due to the particularity of the blast furnace production environment, such as high temperature and loud noise, it is necessary to make a quick judgment based on the on-site situation.

[0005] In view of the above problems, it is particularly important to carry out special training for operators to improve their on-site judgment ability. To this end, the utility model provides a training device for improving the on-site judgment ability of operators. Utility Model Content

[0016] Easy to operate and maintain: The device has a simple structure and is easy to operate, allowing operators to quickly master how to use it. At the same time, the water guide slope and drainage pipe design at the bottom of the box make cleaning and drainage more convenient, which is conducive to the daily maintenance of the equipment.

[0017] Efficient training: By using this training device, operators can become familiar with and master the methods and techniques for judging the leakage status of water supply pipelines in a short period of time, and improve their ability to judge on site. This efficient training helps to reduce misjudgments and misjudgments in actual production and reduce production losses.

[0018] Strong mobility: The handle design on the upper cover makes the training device highly mobile, which is convenient for training in different locations. This flexibility enables the training device to better adapt to the needs of different production sites.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0023] Refer to 1, a training device for judging the leakage status of a water supply pipeline, comprising a box 1, which is the basic structure of the entire training device and provides a space for other components to be installed and work; an upper cover 2 is sealed on the upper part of the box to ensure the sealing of the box, prevent water or gas leakage, and ensure the accuracy and safety of the experiment. A water inlet 3 and a water outlet 4 are respectively installed on a set of opposite sides of the box, and these two interfaces allow water to flow into and out of the box, simulating an actual water supply system. On the outside of the box, the water inlet is connected to a water inlet pipe 5 simulating industrial water pressure, and a water inlet control valve 6 is installed on the water inlet pipe; the water inlet can simulate the real industrial water pressure environment, making the training closer to the actual situation; the water outlet is connected to a drain pipe 7, and a drain control valve 8 is installed on the drain pipe; in the box, the water inlet and the water outlet are respectively connected to two independent water pipes 9, and both water pipes are provided with pipe joints near the end. The independent water pipes can simulate a part of the actual water supply pipeline and are used to detect the leakage of the transition pipe section; a transition pipe section 10 prefabricated with sand holes of different sizes is detachably installed between the pipe joints of the two water pipes. The design is very clever. By prefabricating sand holes of different sizes, leakage situations of different degrees can be simulated, so as to carry out leakage detection training; a high-pressure air intake pipe 11 is installed at the lower part of the box body, and a check valve 12, a pressure reducing valve 13 and a control valve 14 are installed on the high-pressure air intake pipe in sequence. These components can control and adjust the air pressure in the box body, simulate leakage situations under different pressure environments, and improve the comprehensiveness and practicality of the training; a pressure gauge 15 for detecting the sealing pressure in the box body is also installed on the box body or the upper cover, which is used to detect the sealing pressure in the box body, so that the trainee can intuitively understand the current pressure state, so as to better judge the leakage.

[0024] Further preferably, the water pipe is provided with at least one U-shaped pressure stabilizing section 9-1, which can stabilize the water flow, reduce the influence of water pressure fluctuations on the experimental results, and improve the accuracy of the experiment.

[0025] Further preferably, a water guide slope is provided at the bottom of the box body, a discharge pipe 16 is installed on the box body at the bottom of the water guide slope, and a control valve 17 is installed on the discharge pipe to allow water in the box body to be discharged smoothly to avoid water accumulation; the drain pipe and the control valve can control the speed and amount of drainage.

[0026] Further preferably, a safety valve 18 is installed on the box body, which is an important safety device. When the pressure in the box body is too high, the safety valve will automatically open to release the pressure to protect the safety of the box body and the user.

[0027] Further preferably, a handle 19 is provided on the upper cover or the box body. The handle design makes it easier to open the box cover, and the upper cover is sealed with the box body for easier transportation and movement, thereby improving the portability of the device.

[0028] Working principle of this utility model:

[0029] First, the top cover is removed and the transition pipe section with tiny holes is precisely installed on the joint between the two water pipes, making sure it is tight and seamless to prevent any water leakage. Then, the top cover is reinstalled.

[0030] Next, open the control valve of the high-pressure air inlet pipe, and close the drainage control valve on the drainage pipe and the discharge control valve on the discharge pipe. Then, inject high-pressure air into the box until the preset pressure value is reached and maintain this constant pressure state.

[0031] After that, open the water inlet control valve on the water inlet pipe and the drainage control valve on the drainage pipe. At this time, the water supply pressure needs to be adjusted. A key phenomenon will occur: when the water supply pressure exceeds the pressure of the compressed air in the box, the transition pipe section in the box will leak; conversely, if the water supply pressure is lower than the compressed air pressure in the box, the compressed air will penetrate into the water through the sand hole.

[0032] The operator only needs to observe the water flow at the outlet of the drain pipe to quickly determine whether there is a leak in the transition pipe section. At the same time, by observing the state of the compressed air mixed in the water, the size of the leaking sand hole can be further determined. This method is intuitive and efficient, and provides great convenience for detecting and locating leaks.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
