Description

Technical Field

[0001] This utility model relates to the field of boiler early warning technology, and specifically discloses an industrial boiler monitoring and early warning device. Background Technology

[0002] Excessive internal pressure in a boiler is a serious safety hazard, which can be caused by factors such as a stuck safety valve, a malfunctioning pressure gauge, a combustion system imbalance, or human error (such as incorrectly closing the pressure relief channel). If not addressed promptly, pressure exceeding the boiler's design limits can lead to various consequences, ranging from boiler deformation, weld cracking, and pipe rupture causing high-temperature steam leaks or equipment failure to catastrophic explosions. The massive energy released can instantly destroy the boiler and surrounding facilities, and the flying debris and high-temperature media can trigger secondary accidents such as fires, building collapses, and personal injury.

[0003] When the internal pressure of a boiler is too high, and given that some existing safety valves and pressure gauges are inaccurate and all the conditions mentioned above are met, the boiler is very likely to explode. Existing boilers use modern detection equipment, most of which are various electronic sensors, such as capacitive, piezoresistive, and piezoelectric pressure sensors, as well as other devices such as electronic pressure controllers and electronic monitoring systems for safety valves. All of this is based on various high-precision electronic sensors, intelligent control, and cloud management.

[0004] However, seemingly very safe monitoring measures still have significant hidden dangers: in the event of power outages, network outages, or extreme weather such as earthquakes, typhoons, or mudslides, these electronic sensors and controllers may face power outages, network outages, and a lack of supervision. In the event of an explosion, other boilers and stored hazardous chemical materials in the factory may also explode and leak. Therefore, an industrial boiler monitoring and early warning device is proposed to solve this problem. Utility Model Content

[0005] This utility model proposes an industrial boiler monitoring and early warning device. Through glass cover one, glass cover two, glass cover three and airtight piston, it can maintain a relatively safe gas pressure in the boiler, reduce the phenomenon of cylinder explosion when there is no power, network interruption or no response, and solve the problem of boiler explosion hazard during geological disasters.

[0006] This utility model is implemented as follows: an industrial boiler monitoring and early warning device includes a boiler, an inlay frame is provided on the outside of the boiler, and a glass cover one, a glass cover two, a glass cover three and an airtight piston are provided inside the inlay frame.

[0007] The first glass cover is made of tempered glass, the second glass cover is made of unstrengthened borosilicate glass, and the third glass cover is made of ordinary soda-lime glass. The first, second, and third glass covers have different thicknesses, but their inner wall diameters are the same. The first, second, and third glass covers also have different colors, using red, yellow, and blue respectively to distinguish them.

[0008] As a preferred embodiment of the industrial boiler monitoring and early warning device of this utility model, a pressure relief port is fixedly installed on the outer surface of the boiler, and a rubber pad is fixedly installed on the outer surface of the pressure relief port. The rubber pad extends and is fixedly connected to the inner wall of the pressure relief port.

[0009] As a preferred embodiment of the industrial boiler monitoring and early warning device of this utility model, the rubber pad has two annular grooves on its outer surface outside the pressure relief port, and a spiral groove is formed on the inner wall of the rubber pad inside the pressure relief port.

[0010] As a preferred embodiment of the industrial boiler monitoring and early warning device of this utility model, a second rubber pad is fixedly installed on the outer surface of the mounting frame. The outer surface of the second rubber pad is in close contact with the outer surface of the first rubber pad. The outer surface of the second rubber pad is provided with annular protrusions and spiral protrusions. The second rubber pad is in contact with the annular groove of the first rubber pad through the annular protrusions. The second rubber pad is threadedly connected to the spiral groove of the first rubber pad through the spiral protrusions.

[0011] In a preferred embodiment of this utility model, the outer surface of the mounting frame is detachably connected to the outer surface of the pressure relief port via bolts.

[0012] As a preferred embodiment of the industrial boiler monitoring and early warning device of this utility model, an annular fixing frame is fixedly installed on the outer surface of the mounting frame, and the outer surface of the fixing frame is fixedly connected to the outer surfaces of both ends of the glass cover one, glass cover two and glass cover three. A protective shell is fixedly installed on the outer surface of the fixing frame, and a circular array of ventilation slots is opened on the inner side of the protective shell.

[0013] As a preferred embodiment of the industrial boiler monitoring and early warning device of this utility model, the outer surface of the mounting frame is rotatably connected to a handle, the inner wall of the handle is threadedly connected to a transmission rod, the transmission rod is slidably connected to the inner wall of the mounting frame and the fixed frame, and one end of the transmission rod is rotatably connected to the outer surface of the airtight piston.

[0014] The beneficial effects of this utility model are:

[0015] 1. This industrial boiler monitoring and early warning device, through the cooperation between glass cover one, glass cover two, glass cover three and airtight piston, utilizes the different materials of glass cover one, glass cover two and glass cover three, with compressive strength decreasing sequentially from glass cover one to glass cover three. Therefore, when the airtight piston is located in the position of glass cover three, if the air pressure exceeds the bearing capacity of glass cover three, glass cover three will crack or shatter. When glass cover three shatters, the sound generated can attract the attention of the on-duty personnel. At the same time, after glass cover three shatters, the high-pressure gas in the cylinder can be discharged outside the boiler, so that the boiler maintains a relatively safe air pressure, reducing the possibility of cylinder explosion due to power outage, network failure or no response, and solving the problem of boiler explosion hazards during geological disasters.

[0016] 2. This industrial boiler monitoring and early warning device, through the cooperation of rubber pad one, rubber pad two, annular groove, annular protrusion, spiral groove and spiral protrusion, can achieve a good sealing effect when the gas pressure inside the boiler rises. At the same time, the spiral groove of rubber pad one and the spiral groove of rubber pad two can connect, which can significantly reduce the probability of gas escaping from the boiler through the gap between rubber pad one and rubber pad two, making the connection point of the device more airtight and practical.

[0017] 3. This industrial boiler monitoring and early warning device, through the cooperation between the pressure relief port and the first rubber pad, the material of the first rubber pad near the pressure relief port is hard rubber, which reduces the phenomenon of bulging between the first rubber pad and the pressure relief port. The closer the first rubber pad is to the outside, the softer the material is, so that the first rubber pad can maintain relatively good airtightness and also facilitate the insertion and installation of the second rubber pad.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-5 An industrial boiler monitoring and early warning device includes a boiler 1, an inlay frame 2 is provided on the outside of the boiler 1, and a glass cover 3, a glass cover 4, a glass cover 5 and an airtight piston 6 are provided inside the inlay frame 2.

[0027] Glass cover 1 (3) is made of tempered glass, glass cover 2 (4) is made of unstrengthened borosilicate glass, and glass cover 3 (5) is made of ordinary soda-lime glass. Glass covers 1 (3), 2 (4), and 3 (5) have different thicknesses, but their inner wall diameters are the same. In addition, glass covers 1 (3), 2 (4), and 3 (5) are also different in color, using red, yellow, and blue respectively to distinguish them.

[0028] In this embodiment: through the cooperation between glass cover 3, glass cover 4, glass cover 5 and airtight piston 6, based on the different materials of glass cover 3, glass cover 4 and glass cover 5, the compressive strength decreases sequentially from glass cover 3 to glass cover 5. Therefore, when the airtight piston 6 is located at the position of glass cover 5, if the air pressure is higher than the bearing capacity of glass cover 5, glass cover 5 will crack or shatter. When glass cover 5 shatters, the sound produced can attract the attention of the on-duty personnel. At the same time, after glass cover 5 shatters, the high-pressure gas in the cylinder can be discharged to the outside of boiler 1, so that boiler 1 maintains a relatively safe air pressure, reducing the phenomenon of cylinder explosion due to power failure, network failure or no response, and solving the problem of boiler 1 being prone to explosion during geological disasters.

[0029] As a technical optimization of this utility model, a pressure relief port 7 is fixedly installed on the outer surface of the boiler 1, and a rubber pad 8 is fixedly installed on the outer surface of the pressure relief port 7. The rubber pad 8 extends and is fixedly connected to the inner wall of the pressure relief port 7.

[0030] In this embodiment, the rubber pad 8 can cover the inner wall and the outside of the pressure relief port 7, ensuring that it can contact the external rubber pad 11, thereby reducing the occurrence of gas sealing.

[0031] As a technical optimization of this utility model, the rubber pad 8 has two annular grooves 9 on its outer surface outside the pressure relief port 7, and the rubber pad 8 has a spiral groove 10 on its inner wall outside the pressure relief port 7.

[0032] In this embodiment, the material of the rubber pad 8 near the pressure relief port 7 is hard rubber, which reduces the phenomenon of bulging between the rubber pad 8 and the pressure relief port 7. The closer the rubber pad 8 is to the outside, the softer the material.

[0033] As a technical optimization of this utility model, a second rubber pad 11 is fixedly installed on the outer surface of the mounting frame 2. The outer surface of the second rubber pad 11 is in close contact with the outer surface of the first rubber pad 8. The outer surface of the second rubber pad 11 is provided with annular protrusions 12 and spiral protrusions 13. The second rubber pad 11 contacts the annular groove 9 of the first rubber pad 8 through the annular protrusions 12. The second rubber pad 11 is threadedly connected to the spiral groove 10 of the first rubber pad 8 through the spiral protrusions 13.

[0034] In this embodiment: when connecting rubber pad 1 8 and rubber pad 2 11, rubber pad 2 11 can be rotated and inserted into the inner wall of rubber pad 1 8, so that the annular protrusion 12 of rubber pad 2 11 and the annular groove 9 of rubber pad 1 8 come into contact with each other. At the same time, the spiral protrusion 13 of rubber pad 2 11 can be spirally inserted into the spiral groove 10 of rubber pad 1 8. Thus, when the gas pressure inside the boiler 1 rises, the annular groove 9 of rubber pad 1 8 and the annular protrusion 12 of rubber pad 2 11 can play a good sealing role. Meanwhile, the spiral groove 10 of rubber pad 1 8 and the spiral groove 10 of rubber pad 2 11 can play a connecting role, reducing the gas from being discharged from the boiler 1 through the gap between rubber pad 1 8 and rubber pad 2 11.

[0035] As a technical optimization of this utility model, the outer surface of the mounting bracket 2 is detachably connected to the outer surface of the pressure relief port 7 by bolts.

[0036] In this embodiment, the mounting bracket 2 can be installed on the pressure relief port 7 by bolts to prevent excessive air pressure from pushing the rubber pad 2 11 and the pressure relief port 7 outward. At the same time, the mounting bracket 2 and the rubber pad 2 11 can also be replaced by bolts.

[0037] As a technical optimization of this utility model, an annular fixing frame 14 is fixedly installed on the outer surface of the mounting frame 2. The outer surface of the fixing frame 14 is fixedly connected to the outer surfaces of both ends of the glass cover 3, the glass cover 4, and the glass cover 5. A protective shell 15 is fixedly installed on the outer surface of the fixing frame 14. A circular array of ventilation slots is opened on the inner side of the protective shell 15.

[0038] In this embodiment, the annular fixing frame 14 serves to fix the glass cover 3, the glass cover 4, and the glass cover 5. At the same time, when the airtight piston 6 moves toward the protective shell 15, the gas between the protective shell 15 and the airtight piston 6 can be discharged through the exhaust groove opened in the protective shell 15.

[0039] As a technical optimization of this utility model, a handle 16 is rotatably connected to the outer surface of the inlay frame 2, and a transmission rod 17 is threadedly connected to the inner wall of the handle 16. The transmission rod 17 is slidably connected to the inner wall of the inlay frame 2 and the fixed frame 14, and one end of the transmission rod 17 is rotatably connected to the outer surface of the airtight piston 6.

[0040] In this embodiment: the mounting bracket 2 can provide support for the handle 16, and when the handle 16 is rotated, it can drive the transmission rod 17 to move, and the transmission rod 17 can drive the airtight piston 6 to move.
