Technical Field

[0001] The utility model relates to the technical field of steam generators, and particularly relates to a steam generator with an explosion-proof structure. Background Technique

[0002] A steam generator, commonly known as a steam boiler, is a heating device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. Steam generators can be divided into three types according to the fuel (electricity, oil, gas): electric steam generators, oil-fired steam generators, and gas-fired steam generators.

[0003] Electric steam generators are an environmental protection product developed in recent years, and their application scope is constantly expanding. Due to the relatively large heating power and large current of existing electric steam generators, they are more likely to generate a large amount of steam. Since the effect of generating steam by electric steam generators is good, it is easy to occur that the steam inside the steam generator is not transported in time, resulting in excessive internal steam pressure, thus posing an explosion risk. Moreover, the explosion-proof ability of existing electric steam generators is poor, and it is very difficult to be promoted in flammable and explosive occasions.

[0004] Therefore, it is very necessary for us to propose a steam generator with an explosion-proof structure to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a steam generator with an explosion-proof structure. Through the mutual cooperation of the internal parts of the monitoring mechanism, the explosion-proof performance of the steam generator main body can be improved, and the high-pressure steam pressure inside the steam generator main body can be monitored. Through the mutual cooperation of the internal parts of the pressure relief mechanism, the steam with too high pressure in the steam generator main body can be discharged from the inside of the steam generator main body, and the pressure inside the steam generator main body can be relieved, so as to solve the problems in the prior art that due to the good effect of generating steam by electric steam generators, it is easy to occur that the steam inside the steam generator is not transported in time, resulting in excessive internal steam pressure, thus posing an explosion risk, and the explosion-proof ability of existing electric steam generators is poor, and it is very difficult to be promoted in flammable and explosive occasions.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A steam generator with an explosion-proof structure, including a steam generator main body, wherein a monitoring mechanism is fixedly installed inside the steam generator main body and penetrates through one side of the steam generator main body, and a pressure relief mechanism is rotatably connected to the top end of the steam generator main body and penetrates into the inside of the steam generator main body and is located on both sides of the monitoring mechanism.

[0007] Preferably, the monitoring mechanism includes a steam pipe, which is fixedly connected to one side of the steam generator body and penetrates into the interior of the steam generator body. An anti-rust coating is sleeved on the inner wall of the steam generator body. One side of the anti-rust coating is fixedly connected with an explosion-proof aluminum alloy layer, and one side of the explosion-proof aluminum alloy layer is fixedly connected with a surface metal layer. A pressure detector is fixedly connected to the top end inside the steam generator body. The top end of the pressure detector is fixedly connected with a control module, which is located inside the steam generator body. Telescopic push rods are fixedly connected to both sides of the control module and are slidably connected to the inside of the steam generator body.

[0008] Preferably, the pressure relief mechanism includes a pressure relief pipe, which is fixedly connected to the top end of the steam generator body. The bottom end of the pressure relief pipe is rotatably connected with a connecting pipe, which penetrates through the pressure relief pipe into the interior of the steam generator body. Support columns are sleeved and fixed around the outer wall of the connecting pipe. One side of the support column away from the connecting pipe is fixedly connected with a transmission blade. The top end inside the inner wall of the connecting pipe is fixedly connected with a support plate, which is located inside the pressure relief pipe. The top end of the support plate is fixedly connected with a connecting shaft, and a plurality of fans are fixedly sleeved on the outer wall of the connecting shaft. A plurality of arc-shaped partitions are fixedly connected to the top end of the connecting pipe and are in contact with the inner wall of the pressure relief pipe.

[0009] Preferably, a control valve is installed and connected to one side of the inner wall of the steam generator body where the steam pipe penetrates. A telescopic groove matching the telescopic push rod is provided on the inner wall of the steam generator body. The internal structure of the explosion-proof aluminum alloy layer is honeycomb-shaped, and the material of the surface metal layer is an explosion-proof plate.

[0010] Preferably, a plurality of limit grooves matching the telescopic push rods are connected and provided around the outer wall of the connecting pipe. The connecting pipe is rotatably connected to the steam generator body and the pressure relief pipe through bearings.

[0014] When the pressure detector detects that the internal pressure of the steam generator body is too high, the control module starts the telescopic movement of the telescopic push rod, so that the telescopic push rod moves out of the connecting pipe, releasing the rotational limit of the connecting pipe. At the same time, the rising steam pushes the transmission blade to rotate, causing the transmission blade to drive the support column to rotate, and the transmission blade drives the connecting pipe to rotate through the support column. The rotation of the connecting pipe drives the top support plate to rotate. At the same time, the rising steam pushes the fan on the outer wall of the connecting shaft to rotate, so that the fan gathers the high-pressure steam inside the connecting pipe. At the same time, the rotation of the connecting pipe drives the arc partition to rotate, so that the rotation of the arc partition releases the sealing isolation of the heat dissipation holes at the top of the exhaust pipe, and the high-pressure steam is discharged from the top of the exhaust pipe through the heat dissipation slots, thus completing the pressure relief operation of the high-pressure steam inside the steam generator body and reducing the explosion risk caused by too high internal pressure of the steam generator body.

A pressure relief mechanism 3 is rotatably connected to the top of the steam generator main body 1 and penetrates into the steam generator main body 1 and is located on both sides of the monitoring mechanism 2. Through the mutual cooperation of the internal parts of the monitoring mechanism 2, the explosion-proof performance of the steam generator main body 1 can be improved, and the high-pressure steam pressure inside the steam generator main body 1 can be monitored. Through the mutual cooperation of the internal parts of the pressure relief mechanism 3, the steam with too high pressure in the steam generator main body 1 can be discharged from the inside of the steam generator main body 1, and the pressure relief operation is performed on the inside of the steam generator main body 1.

[0025] Referring to the attached Figures 1-5 drawings, the monitoring mechanism 2 includes a steam pipe 201. The steam pipe 201 is fixedly connected to one side of the steam generator main body 1 and penetrates into the steam generator main body 1. An antirust coating 202 is sleeved on the inner wall of the steam generator main body 1. One side of the antirust coating 202 is fixedly connected to an explosion-proof aluminum alloy layer 203. One side of the explosion-proof aluminum alloy layer 203 is fixedly connected to a surface metal layer 204. A pressure detector 205 is fixedly connected to the top inside the steam generator main body 1. The top of the pressure detector 205 is fixedly connected to a control module 206 and is located inside the steam generator main body 1. Telescopic push rods 207 are fixedly connected to both sides of the control module 206 and are slidably connected to the inside of the steam generator main body 1. Through the mutual cooperation of the internal parts of the monitoring mechanism 2, the explosion-proof performance of the steam generator main body 1 can be improved, and the high-pressure steam pressure inside the steam generator main body 1 can be monitored.

[0026] Referring to the attachedFigures 1-5 , the pressure relief mechanism 3 includes a pressure relief pipe 301. The pressure relief pipe 301 is fixedly connected to the top of the steam generator main body 1. The bottom end of the pressure relief pipe 301 is rotatably connected to a connecting pipe 302, and the connecting pipe 302 penetrates through the pressure relief pipe 301 to the inside of the steam generator main body 1. A support column 303 is fixedly sleeved around the outer wall of the connecting pipe 302. A transmission blade 304 is fixedly connected to the side of the support column 303 away from the connecting pipe 302. The top end of the inner wall of the connecting pipe 302 is fixedly connected to a support plate 305, and the support plate 305 is located inside the inner wall of the pressure relief pipe 301.

The top end of the connecting pipe 302 is fixedly connected to a plurality of arc-shaped partitions 308, which are attached to the inner wall of the pressure relief pipe 301. Through the mutual cooperation of the internal parts of the pressure relief mechanism 3, the steam with too high pressure in the steam generator main body 1 can be discharged from the inside of the steam generator main body 1, and the pressure relief operation can be carried out on the inside of the steam generator main body 1.

The internal structure of the explosion-proof aluminum alloy layer 203 is honeycomb-shaped, and the material of the surface metal layer 204 is an explosion-proof plate. Due to the honeycomb-shaped internal structure of the explosion-proof aluminum alloy layer 203, when the pressure inside the steam generator main body 1 is too high, the explosion-proof aluminum alloy layer 203 can absorb the energy of the pressure inside the steam generator main body 1, thereby improving the explosion-proof performance of the steam generator main body 1.

The connecting pipe 302 is rotatably connected to the steam generator main body 1 and the pressure relief pipe 301 through bearings. The transmission blade 304 and the support column 303 are fixedly connected at a certain inclination angle. Due to the fact that the transmission blade 304 and the support column 303 are fixedly connected at a certain inclination angle, when the steam rises, it is convenient to push the transmission blade 304 to rotate.

Due to the fact that a heat dissipation groove matching the heat dissipation holes at the top end of the pressure relief pipe 301 is provided between the plurality of arc-shaped partitions 308, it is convenient for the arc-shaped partitions 308 to rotate so that the high-pressure steam is discharged from the top end of the pressure relief pipe 301 through the heat dissipation groove, and the pressure relief operation of the high-pressure steam inside the steam generator main body 1 is completed.

[0030] The working principle of this utility model:

[0031] Refer to the appended description Figures 1-5 Figures 1-5 , steam is generated by electric heating inside the steam generator main body 1. The generated high-pressure steam is transported through the steam pipe 201. At the same time, through the protective coating on the inner wall surface of the steam generator main body 1, the generation of scale on the inner wall of the steam generator main body 1 can be reduced, thereby improving the quality of the high-pressure steam generated by the steam generator main body 1. At the same time, through the explosion-proof aluminum alloy layer 203 and the surface metal layer 204 on the inner wall of the steam generator main body 1, the overall explosion-proof performance of the steam generator main body 1 can be improved, thereby improving the compressive performance of the steam generator main body 1. At the same time, the internal pressure of the steam generator main body 1 can be monitored in real time through the pressure detector 205, and the telescopic push rod 207 controlled by the control module 206 is used to limit and fix the connecting pipe 302, so as to complete the pressure monitoring inside the steam generator main body 1 and improve the overall explosion-proof performance of the steam generator main body 1;

[0032] Refer to the appended description Figures 1-5 Figures 1-5 , when the pressure detector 205 detects that the internal pressure of the steam generator main body 1 is too high, the control module 206 starts the telescopic movement of the telescopic push rod 207, so that the telescopic push rod 207 moves out of the connecting pipe 302, releasing the rotational limit of the connecting pipe 302. At the same time, the rising steam pushes the transmission blade 304 to rotate, so that the rotation of the transmission blade 304 drives the support column 303 to rotate, so that the transmission blade 304 drives the connecting pipe 302 to rotate through the support column 303. The rotation of the connecting pipe 302 drives the top support plate 305 to rotate. At the same time, the rising steam pushes the fan 307 on the outer wall of the connecting shaft 306 to rotate, so that the fan 307 gathers the high-pressure steam inside the connecting pipe 302. At the same time, the rotation of the connecting pipe 302 drives the arc-shaped partition 308 to rotate, so that the rotation of the arc-shaped partition 308 releases the sealing isolation of the heat dissipation holes at the top of the air release pipe 301, and the high-pressure steam is discharged from the top of the air release pipe 301 through the heat dissipation grooves, so as to complete the pressure relief operation of the high-pressure steam inside the steam generator main body 1 and reduce the explosion risk caused by too high internal pressure of the steam generator main body 1.
