Description

Technical Field

[0001] The present application relates to the technical field of container leakage detection, and in particular to a boiler pressure vessel leakage detection device. Background Art

[0002] Boiler pressure vessel is the full name of boiler and pressure vessel. Because they are both special equipment, they occupy a very important position in production and life. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. The boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production. Pressure vessels will age after long-term use. The aged pressure vessels are prone to leakage accidents during use, affecting the safe production of the enterprise.

[0003] The patent document with application number 202121984192.6 discloses a boiler pressure vessel leakage detection device, including a detection box and a water tank, wherein a pumping mechanism for pumping water into the detection box and a return mechanism for pumping water out of the detection box are connected between the detection box and the water tank, a boiler pressure vessel body is arranged inside the detection box, blocks are arranged on the inner walls on opposite sides of the detection box, two buoyancy plates are arranged on the blocks, a water level gauge is installed on the outer wall of one side of the detection box, a lifting column is connected to one side of the upper wall of the buoyancy plate, the top of the lifting column slides through the upper wall of the detection box, a scale plate matching the lifting column is arranged on the outer wall of the top of the detection box, and an inflation mechanism for inflating the boiler pressure vessel body is arranged on the detection box. Compared with the prior art, the utility model has the advantages that by comparing the relative height changes of the lifting column and the scale plate, it is possible to judge whether the boiler pressure vessel body is leaking, and it is more intuitive and easy to observe.

[0004] In the above technical solution, before using the boiler, a detection device is needed to detect the boiler for leakage to avoid leakage of the boiler and bring danger to people. However, the existing device is large in size, which makes the device inconvenient to use; therefore, we propose a boiler pressure vessel leakage detection device to solve this problem.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] The present application embodiment discloses a boiler pressure vessel leakage detection device. Figure 1-4 A boiler pressure vessel leakage detection device comprises a boiler body 1, and a mounting mechanism is arranged on the top of the boiler body 1; the mounting mechanism comprises a base 5, and the base 5 is arranged on the top of the boiler body 1, and the top of the base 5 is fixedly connected to two connecting frames 14, and the inner sides of the two connecting frames 14 are rotatably connected to threaded rods 11, and the outer sides of the two threaded rods 11 are threadedly connected to the same moving plate 12, and the outer side of the connecting frame 14 is fixedly connected to a motor 7, and one end of the output shaft of the motor 7 is connected to a rotating rod 8 through a coupling transmission, and the outer side of the rotating rod 8 is fixedly connected to two first bevel gears 9, and the outer sides of the two first bevel gears 9 are meshed with second bevel gears 10, and the bottoms of the second bevel gears 10 are fixedly connected to the tops of the threaded rods 11, and the moving plate 12 is slidably connected to the inner sides of the connecting frames 14, and the outer side of the base 5 is fixedly connected to a controller 4, and the rotating rod 8 is rotatably connected to the inner sides of the two connecting frames 14, and the bottom of the moving plate 12 is fixedly connected to a solenoid valve 13, and the inner side of the solenoid valve 13 is fixedly connected to a mounting pipe.

[0024] Reference Figure 1-4 A pressure transmitter 15 is installed at the bottom of the movable plate 12 , and a mounting frame 3 is installed on the outer side of the boiler body 1 .

[0025] Reference Figure 1-4, the top of the connecting frame 14 is fixedly connected with an input pipe 2, the input pipe 2 passes through the connecting frame 14 and the movable plate 12 to communicate with the mounting pipe installed below, and a mounting hole 6 is opened on the base 5; by installing the device on the pipeline input port of the boiler body 1, the signal is transmitted to the motor 7 through the controller 4, when the motor 7 rotates, the motor 7 drives the rotating rod 8 to rotate through the coupling at one end of the output shaft, when the rotating rod 8 rotates, the rotating rod 8 drives the two first bevel gears 9 fixedly connected on the outside to rotate at the same frequency and in the same direction, because the outer sides of the two first bevel gears 9 are meshed with the second bevel gears 10, the bottoms of the two second bevel gears 10 are fixedly connected with the threaded rod 11, and the threaded rod 11 is rotatably connected to the inner side of the connecting frame 14, so the rotation of the motor 7 can drive the two threaded rods 11 to rotate, thereby driving the movable plate 12 threadedly connected on the outer sides of the two threaded rods 11 to move, and the mounting pipe passes through the mounting hole 6 and is inserted into the pipeline input port; a sealing ring is installed on the outer side of the mounting pipe, and the setting of the sealing ring increases the sealing of the device to prevent gas leakage.

[0026] The implementation principle of a boiler pressure vessel leakage detection device in the embodiment of the present application is as follows: when the staff uses this device, the staff first installs the device on the pipeline input port of the boiler body 1, and transmits the signal to the motor 7 through the controller 4. When the motor 7 rotates, the motor 7 drives the rotating rod 8 to rotate through the coupling at one end of the output shaft. When the rotating rod 8 rotates, the rotating rod 8 drives the two first bevel gears 9 fixedly connected on the outside to rotate at the same frequency and in the same direction. Since the outer sides of the two first bevel gears 9 are meshed with second bevel gears 10, the bottoms of the two second bevel gears 10 are fixedly connected with threaded rods 11, and the threaded rods 11 are rotatably connected to the inner side of the connecting frame 14, the rotation of the motor 7 can drive the two threaded rods 11 to rotate, thereby driving the movable plate 12 threadedly connected to the outer sides of the two threaded rods 11 to move, and the mounting pipe is inserted into the pipeline input port through the mounting hole 6, and then the boiler is closed. The valves and other devices arranged on the furnace body 1 open the stop valve arranged on the input pipe 2, and input the external gas into the inner side of the installation pipe and then into the inner side of the boiler body 1 through the external air pump, so that the solenoid valve 13 is in the open state, and at this time, the pressure value is detected by the pressure transmitter 15. At the beginning, due to the continuous increase in the pressure in the boiler, after the pressure transmitter 15 transmits the electrical signal to the controller 4, the controller 4 displays the pressure value on the front side display screen of the boiler body 1. It can be seen that the pressure value is constantly increasing. When the pressure value reaches a certain level (for example, 1.1 standard atmospheric pressures), the air pump stops working, the stop valve is closed, and the pressure transmitter 15 records the pressure value after a certain time interval, for example, 10 seconds, and records the pressure value data for 1 hour. If the pressure value data is always within a value and almost unchanged, it means that there is no leakage in the boiler. If the pressure value shows a trend of gradually decreasing, it means that there is a leakage in the boiler.
