Description

Technical Field

[0001] The utility model relates to the technical field of boiler detection, in particular to an auxiliary device for boiler leakage detection. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The boiler is a device that uses the heat energy released by fuel combustion or other heat energy to heat the working medium water or other fluids to certain parameters. According to different uses, it can be divided into several categories: power station boilers, industrial boilers, domestic boilers and special boilers.

[0003] According to GB / T36699-2018, "Technical Specifications for Liquid and Gaseous Fuel Burners for Boilers," in-use burners must be inspected annually starting April 1, 2019. Before inspecting a boiler, be sure to drain all water and open all access doors to ensure thorough ventilation and cooling. Effective measures should be taken to isolate the water supply, sewage, and steam lines connected to the boiler to prevent accidental vapor backflow and potential harm to inspectors. If the boiler is fueled by oil or gas, the oil or gas source must also be completely shut off.

[0004] Leak detection is one of the inspection items for boilers. The specific operation method is to introduce compressed air into the boiler to make the boiler internal pressure state, or to extract the air in the boiler to make the boiler internal pressure state, and monitor the pressure maintenance time through detection instruments such as barometers;

[0005] However, current inspections are all carried out at room temperature. If there are tiny pores in the boiler that cause gas or liquid leakage, the leakage of the tiny pores at room temperature is not obvious and difficult to detect. The working state of the boiler is high temperature, and the tiny pores will expand at high temperature. The undetected tiny pores will directly affect the safety of production. Utility Model Content

[0037] Example 1:

[0038] See also Figure 1-10 The utility model provides a technical solution: an auxiliary device for boiler leakage detection, comprising a base 1, on which are provided two support plates 2 for fixing the two ends of a boiler 3, respectively, and a heating component 8 for heating the boiler 3 is provided between the two support plates 2;

[0039] A slide rod 6 is provided between the two support plates 2, and both ends of the slide rod 6 are connected to the two support plates 2 respectively, and the heating component 8 is slidably fitted on the slide rod 6;

[0040] It also includes a driving mechanism, which is used to push the heating component 8 to move along the sliding rod 6.

[0041] In this solution, the heating component 8 is mounted on the boiler 3, and the heating component 8 can be pushed along the slide rod 6 by a driving mechanism. An air intake pipe is also provided on the side of the boiler 3, and a detection component 9 is provided at the end of the air intake pipe away from the boiler 3. When the boiler 3 is heated by the heating component 8, the detection component 9 can be started to detect leakage of the boiler 3.

[0042] When in use, first turn on the heating assembly 8, which heats the boiler 3, and at the same time start the driving mechanism, which pushes the heating assembly 8 to move along the slide rod 6, so that the heating assembly 8 can heat the boiler 3 in all directions. If there are tiny pores in the boiler that cause gas or liquid leakage, the tiny pores will expand after the boiler 3 is heated, making it easier to find the tiny pores on the boiler 3 during subsequent leak detection of the boiler 3;

[0043] The driving mechanism pushes the heating component 8 to move along the slide rod 6, and the heating component 8 can heat the boiler 3 during the movement. If there are tiny pores in the boiler 3, the volume of the tiny pores will expand, thereby achieving the purpose of reducing the probability of missed detection when there are tiny pores on the boiler and improving production safety.

[0044] The detection component 9 includes a controller and an air pump 91. The inlet of the air pump 91 is connected to an air intake pipe, and the outlet of the air pump 91 is connected to an air outlet pipe 95. The air outlet pipe 95 is fixedly connected to the air inlet pipe through a flange, and a rubber pad is provided between the two flanges. A pressure gauge 92 is provided on the air pump 91, and the pressure gauge 92 is electrically connected to the controller. A buzzer 93 and a warning light 94 are also provided on the air pump 91, and the buzzer 93 and the warning light 94 are electrically connected to the controller.

[0045] During use, after the boiler 3 is heated by the heating component 8, the air pump 91 is started by the controller, and the air pump 91 discharges the compressed air through the outlet pipe 95 and enters the boiler 3 through the inlet pipe, so that the inside of the boiler 3 is in a high-pressure state. The pressure fluctuation value inside the boiler 3 is detected in real time by the barometer 92. When the air pressure inside the boiler 3 is stable and there is no fluctuation within a certain period of time, there are no tiny pores in the boiler 3. When the air pressure inside the boiler 3 fluctuates within a certain period of time, it indicates that there are tiny pores in the boiler 3, and the controller transmits an electrical signal to the buzzer 93 and the warning light 94, so that the staff can record and process the data in time.

[0046] Among them, the air pump model is HG-120-C 220V; the pressure gauge model is MHY-22148; the controller model is 6ES74122EK070AB0; the warning light model is AD56-22DS; and the buzzer model is MS1285+2003PB.

[0050] After starting the heating component 8, the motor 4 is then started, and the motor 4 controls the rotation of the lead screw, which pushes the heating component 8 to move along the slide rod 6, so that the heating component 8 can heat the entire cylinder of the boiler 3.

[0052] In this embodiment, a slider 7 is provided on the side of the connecting ring 81 , and the slider 7 is connected to the lead screw and slidably cooperates with the slide rod 6 .

The surface of the outer rod 121 and the inner rod 124 is provided with a return spring 14, and the top of the inner rod 124 is provided with a limit plate. The two ends of the return spring 14 respectively abut against the limit plate and the inner side of the semicircular plate. The support rod 12 can adjust the length by elastic extension and contraction, so that the pulley 13 and the boiler 3 are in contact, which is convenient for preventing the heating wire 83 or the heating tube 85 from contacting and rubbing with the boiler 3 and causing damage.

[0058] In this embodiment, fixing rods 10 are provided on all four sides of the top of the base 1 , and a protective plate 11 is provided between any two adjacent fixing rods 10 .
