Description

Technical Field

[0001] This invention relates to the field of electromagnetic boiler technology, specifically to an internal and external electromagnetic boiler. Background Technology

[0002] Electromagnetic heating steam boilers are specialized thermal energy devices that efficiently convert electrical energy into heat energy based on the principle of electromagnetic induction heating, causing water to be heated and vaporized to produce saturated steam or superheated steam that meets industrial and commercial needs. They differ from traditional gas-fired steam boilers (which rely on combustion heat release) and resistance steam boilers (which rely on resistance wire heating), possessing core advantages such as high efficiency and energy saving, safety and environmental protection, and intelligent controllability. They are one of the mainstream devices in current "coal-to-electricity" and "energy-saving renovation" scenarios.

[0003] When sewage is continuously discharged into the cylinder for a long time, a large amount of scale will gradually adhere to the inner wall of the sewage pipe due to the continuous deposition of minerals in the sewage. If this scale is not cleaned for a long time, it will continue to thicken and reduce the diameter of the sewage pipe, thereby interfering with the normal drainage of the sewage pipe. Summary of the Invention

[0004] To solve the above technical problems, the present invention is implemented through the following technical solution: an internal and external electromagnetic boiler, comprising:

[0005] The cylinder has end caps fixedly connected to both ends, supports fixedly connected to both sides of the bottom of the cylinder, a manhole fixedly connected to the top of the cylinder, a main steam valve fixedly connected to the middle of the top of the cylinder, a safety valve fixedly connected to the top of the cylinder, a pressure gauge fixedly connected to the top of the cylinder, a water level gauge fixedly connected to the front of the cylinder, a sampling tube seat fixedly connected to the middle of the front of the cylinder, a water supply pipe fixedly connected to the middle of the bottom of the cylinder, a handhole fixedly connected to the side of the cylinder, and a steam-water separator fixedly connected to the top of the inner cavity of the cylinder.

[0006] A coil heating element is used for heating operations, and the side of the coil heating element is fixedly connected to the inner side of the cylinder.

[0007] A sewage discharge component is used to discharge sewage from the inside of the cylinder. The top of the sewage discharge component is fixedly connected to the bottom of the inner cavity of the cylinder.

[0008] The coil heating component includes a furnace chamber and an inner furnace chamber, with four furnace chambers in total. All four furnace chambers are fixedly connected to the inner side of the cylinder. A baffle is fixedly connected to the inner side of each furnace chamber, and the inner side of the baffle is fixedly connected to the side of the inner furnace chamber. An asbestos board is fixedly connected to the side of the inner furnace chamber away from the baffle by fasteners. A support cylinder is fixedly connected to the circumferential side of the inner furnace chamber, and a copper coil is wound on the support cylinder. The copper coil is placed between the furnace chamber and the inner furnace chamber. A handhole is fixedly connected to one side of the inner furnace chamber. A steam pipe is fixedly connected to the side of the inner furnace chamber away from the handhole, and the end of the steam pipe away from the inner furnace chamber is fixedly connected to the inner side of the cylinder. A seamless steel pipe is fixedly connected to the side of the inner furnace chamber near the handhole, and the end of the seamless steel pipe away from the inner furnace chamber is fixedly connected to the inner side of the cylinder.

[0009] Preferably, the sewage discharge component includes a sewage discharge pipe, the top of which is fixedly connected to the bottom of the inner cavity of the cylinder. A fixing frame is fixedly connected to the top of the inner cavity of the sewage discharge pipe, and a sliding rod is fixedly connected to the bottom of the fixing frame. The sliding rod provides guidance for the cleaning mechanism to prevent movement jamming. The elastic force of the second spring can control the reset force to ensure that the mechanism returns to the preset working position after each reset, ensuring the cleaning effect next time. A sliding groove is opened on the side of the sliding rod. A first spring is fixedly connected to the bottom of the fixing frame. The other end of the first spring is fixedly connected to the cleaning mechanism, and the other end of the sewage discharge pipe is fixedly connected to the moving mechanism.

[0010] Preferably, the moving mechanism includes a moving cylinder, the side of which is slidably connected to the inside of the sewage pipe. A circular shaft is evenly arranged on the side of the moving cylinder away from and close to the sewage pipe. One end of the circular shaft is fixedly connected to the moving cylinder, and the other end is slidably connected to the inside of the sewage pipe. A second spring is sleeved on the circular shaft, one end of which is fixedly connected to the inside of the sewage pipe, and the other end is fixedly connected to the side of the moving cylinder.

[0012] Preferably, the scraping assembly includes a scraping shell, a guide plate is fixedly connected to the side of the scraping shell, a connecting shaft is slidably connected to the inner side of the scraping shell, a connecting plate is fixedly connected to the other end of the connecting shaft, a scraper is fixedly connected to the side of the connecting plate away from the connecting shaft, a third spring is sleeved on the connecting shaft, one end of the third spring is fixedly connected to the connecting plate, and the other end of the third spring is fixedly connected to the inner side of the scraping shell. The spring is self-adjusting to ensure cleaning fit. The tension and storage design of the third spring can adaptively adjust the contact pressure of the scraper according to the slight deformation of the inner wall of the drain pipe.

[0013] Preferably, the guiding assembly includes a guiding shell, one side of which is rotatably connected to the side of the scraping shell away from the guide plate, and the other side of which is fixedly connected to the side of the contact frame. The inner sides of the guiding shell, the scraping shell, and the contact frame are all slidably connected to the side of the slide rod.

The elastic adaptive design of the fourth spring avoids the problem of the guide wheel detaching due to the change in the curvature of the inner wall at the bend of the sewage pipe, and realizes that the guide wheel is in contact with the pipe wall throughout the straight pipe section and the bend section.

[0014] Preferably, the contact assembly includes a contact frame, the side of the contact frame away from the guide housing is fixedly connected to the end of the second spring away from the fixed frame, both sides of the contact frame are slidably connected to contact shafts, the other end of the contact shaft is fixedly connected to a contact plate, a fifth spring is sleeved on the contact shaft, one end of the fifth spring is fixedly connected to the inner side of the contact frame, and the other end of the fifth spring is fixedly connected to the contact plate.

[0015] This invention provides an internal and external electromagnetic boiler. It has the following beneficial effects:

[0016] 1. This internal and external electromagnetic boiler is equipped with a coil heating component. The support cylinder supporting the copper coil is made of "refractory cement material with high temperature resistance and insulation properties". It also serves as the "support between the furnace shell and the inner furnace shell" of the boiler. That is, the support cylinder connects and fixes the furnace shell and the inner furnace shell to form a stable double-layer cylinder structure. The copper coil is wound on this support cylinder to ensure that the position of the copper coil is fixed and does not shift.

[0017] 2. This internal and external electromagnetic boiler is equipped with a moving mechanism. During the sewage discharge stage, the cleaning mechanism automatically detaches from the pipe wall after cleaning, with no parts obstructing the water flow channel, ensuring that sewage and scraped-off impurities can be discharged quickly.

[0018] 3. This internal and external electromagnetic boiler is equipped with a guide assembly to prevent the mechanism from shifting due to water flow impact, providing a foundation for the subsequent scraping and cleaning mechanism. The guide wheel is in dynamic contact with the pipe wall, and with the buffering effect of the spring, the frictional resistance with the pipe wall can be reduced, avoiding component wear caused by jamming.

[0019] 4. This internal and external electromagnetic boiler is equipped with a scraping component. When the pipe wall protrudes, the spring is compressed to buffer the movement and prevent the scraper from getting stuck or scratching the pipe wall. When the pipe wall is flat, the spring is stretched to provide stable pressure, ensuring that the scraper always fits the pipe wall without any cleaning gaps, thus improving the thoroughness of cleaning.

[0020] 5. This internal and external electromagnetic boiler is equipped with a contact component. The contact component performs secondary contact cleaning on the pipe wall after the scraper has cleaned it. This can remove small impurities and scale that the scraper missed, and prevent the scraped impurities from remaining and adhering to the inner wall of the drain pipe. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figures 1-3 The present invention provides a technical solution: an internal and external electromagnetic boiler, comprising:

[0034] The cylinder 1 has end caps 2 fixedly connected to both ends, supports 3 fixedly connected to both sides of the bottom of the cylinder 1, a manhole device 4 fixedly connected to the top of the cylinder 1, a main steam valve 5 fixedly connected to the middle of the top of the cylinder 1, a safety valve 6 fixedly connected to the top of the cylinder 1, a pressure gauge 7 fixedly connected to the top of the cylinder 1, a water level gauge 8 fixedly connected to the front of the cylinder 1, a sampling tube seat 11 fixedly connected to the middle of the front of the cylinder 1, a water supply pipe 10 fixedly connected to the middle of the bottom of the cylinder 1, a handhole device 13 fixedly connected to the side of the cylinder 1, and a steam-water separator 14 fixedly connected to the top of the inner cavity of the cylinder 1.

[0035] A coil heating component 12 is used for heating operations, and the side of the coil heating component 12 is fixedly connected to the inner side of the cylinder 1.

[0036] Sewage discharge component 9 is used to discharge sewage inside the cylinder 1. The top of sewage discharge component 9 is fixedly connected to the bottom of the inner cavity of the cylinder 1.

[0037] Please see Figure 4 The coil heating component 12 includes a furnace chamber 121 and an inner furnace chamber 122, with four furnace chambers 121 and four inner furnace chambers 122. All four furnace chambers 121 are fixedly connected to the inner side of the cylinder 1. A baffle 123 is fixedly connected to the inner side of each furnace chamber 121, and the inner side of the baffle 123 is fixedly connected to the side of the inner furnace chamber 122. An asbestos board 124 is fixedly connected to the side of the inner furnace chamber 122 away from the baffle 123 by fasteners. A support is fixedly connected to the circumferential side of the inner furnace chamber 122. The inner furnace liner 122 is fixedly connected to a manhole 127 on one side, and a steam pipe 128 is fixedly connected to the side of the inner furnace liner 122 away from the manhole 127. The end of the steam pipe 128 away from the inner furnace liner 122 is fixedly connected to the inner side of the cylinder 1. A seamless steel pipe 126 is fixedly connected to the side of the inner furnace liner 122 near the manhole 127. The end of the seamless steel pipe 126 away from the inner furnace liner 122 is fixedly connected to the inner side of the cylinder 1.

[0038] This boiler uses four sets of electromagnetic induction copper coils 125 as the core heating elements. The copper coils 125 are installed between the furnace shell 121 and the inner furnace shell 122. The copper coils 125 are kept at a specific distance from the furnace shell 121 and the inner furnace shell 122. The copper coils 125 are wound around the support cylinder 129 and distributed in a ring to ensure that the magnetic field can act evenly on the furnace shell 121 and the inner furnace shell 122.

[0039] The two ends of each copper coil 125 are connected to a dedicated electromagnetic heating control cabinet. The electromagnetic heating control cabinet controls the power supply, power off, leakage protection power off, and power adjustment of the copper coil 125, thereby realizing the control of the heating process.

[0040] When the copper coil 125 is energized, it converts electrical energy into heat energy through electromagnetic induction, and can simultaneously heat the water outside the furnace liner 121 and the water inside the inner furnace liner 122.

[0041] After the electromagnetic heating control cabinet supplies current to the copper coil 125, the copper coil 125 wound on the support cylinder 129 becomes conductive, forming a stable high-frequency alternating electromagnetic field on the circumferential side of the furnace 121 and the inner furnace 122.

[0042] The electromagnetic field acts on the furnace shell 121 and the inner furnace shell 122, causing eddy currents to be generated in the furnace shell 121 and the inner furnace shell 122 themselves. The eddy currents are converted into electromagnetic heat by the resistance of the metal.

[0043] The electromagnetic heat generated by the furnace shell 121 and the inner furnace shell 122 is simultaneously transferred to the water body of the outer cylinder 1 of the furnace shell 121 and the water body inside the inner furnace shell 122, so as to realize the synchronous heating of the inner and outer furnace shells, maximize the utilization of electromagnetic field energy, and reduce heat loss.

[0044] After being electromagnetically heated, the water completes a closed loop of steam generation → separation → circulation within cylinder 1:

[0045] The water outside the furnace 121 and the water inside the inner furnace 122 continuously absorb the electromagnetic heat of the furnace 121. After the temperature rises to the boiling point under the corresponding pressure, it vaporizes and forms a water-steam mixture.

[0046] The steam-water mixture undergoes natural separation inside cylinder 1. The steam, due to its lower density, rises and is either stored or output for use; the water that is not completely vaporized remains in the lower part of cylinder 1 and continues to be heated.

[0047] After the cold water is added to cylinder 1, it mixes with the existing water in the boiler. Due to the high density of the cold water, the low density of the hot water, and the low density of the steam, a density difference is created, driving natural circulation.

[0048] Cold water flows downward through seamless steel pipe 126, while steam or high-temperature water generated after heating moves upward through steam pipe 128.

[0049] The copper coil 125 of this electromagnetic boiler is not ordinary copper wire. Its surface is covered with a high-temperature resistant insulating ceramic tube to achieve insulation protection and high-temperature resistance when the copper coil 125 is energized, and to avoid insulation failure under high temperature environment.

[0050] The support cylinder 129 supporting the copper coil 125 is made of "refractory cement material with high temperature resistance and insulation properties". It also serves as the support between the boiler furnace 121 and the inner furnace 122. That is, the support cylinder 129 connects and fixes the furnace 121 and the inner furnace 122 to form a stable double-layer cylinder structure. The copper coil 125 is wound on this support cylinder 129 to ensure that the position of the copper coil 125 is fixed and does not shift.

[0051] Both the furnace shell 121 and the inner furnace shell 122 are made of metal, providing a carrier for the high-frequency alternating magnetic field generated after the copper coil 125 is energized. In turn, the eddy current heating of the inner and outer cylinders is realized through electromagnetic induction, laying the foundation for subsequent water heating.

[0052] Example 2, please refer to Figure 5Based on Embodiment 1, the present invention provides a technical solution: the sewage discharge component 9 includes a sewage discharge pipe 91, the top of the sewage discharge pipe 91 is fixedly connected to the bottom of the inner cavity of the cylinder 1, a fixing frame 92 is fixedly connected to the top of the inner cavity of the sewage discharge pipe 91, a sliding rod 93 is fixedly connected to the bottom of the fixing frame 92, a sliding groove 94 is provided on the side of the sliding rod 93, a first spring 95 is fixedly connected to the bottom of the fixing frame 92, a cleaning mechanism 96 is fixedly connected to the other end of the first spring 95, and a moving mechanism 97 is fixedly connected to the other end of the sewage discharge pipe 91;

[0053] When the sewage in the cylinder 1 flows into the sewage pipe 91, the water flow will impact the cleaning mechanism 96 inside the pipe, pushing the cleaning mechanism 96 to move axially along the sewage pipe 91;

[0054] The cleaning mechanism 96 maintains contact with the inner wall of the sewage pipe 91, and scrapes and cleans the pipe wall by moving.

[0055] When the cleaning mechanism 96 moves, it will pull the first spring 95 simultaneously, causing the spring to stretch and deform along the preset slide bar 93. The slide bar 93 provides a guide for the cleaning mechanism 96 to move, avoid deviation, and ensure that the cleaning mechanism 96 moves stably against the pipe wall.

[0056] As sewage continues to flow out of the sewage pipe 91, the water flow continuously provides power to the cleaning mechanism 96, propelling it toward the outlet of the sewage pipe 91;

[0057] When the cleaning mechanism 96 moves to a specific position, it will come into squeezing contact with the moving mechanism 97 inside the tube;

[0058] Under the squeezing action of the cleaning mechanism 96, the moving mechanism 97 disengages from the drain pipe 91;

[0059] Finally, the sewage discharged from the cylinder 1, together with the impurities scraped off the pipe wall by the cleaning mechanism 96, is smoothly discharged through the drain pipe 91.

[0060] Please see Figure 6 The moving mechanism 97 includes a moving cylinder 972, the side of which is slidably connected to the inside of the drain pipe 91. A circular shaft 971 is evenly arranged on the side of the moving cylinder 972 away from and close to the drain pipe 91. One end of the circular shaft 971 is fixedly connected to the moving cylinder 972, and the other end is slidably connected to the inside of the drain pipe 91. A second spring 974 is sleeved on the circular shaft 971. One end of the second spring 974 is fixedly connected to the inside of the drain pipe 91, and the other end is fixedly connected to the side of the moving cylinder 972. A second fixing frame 973 is fixedly connected to the inside of the moving cylinder 972, and the inside of the second fixing frame 973 is slidably connected to the side of the slide rod 93.

[0061] When the sewage inside the cylinder 1 is discharged through the drain pipe 91, the cleaning mechanism 96 will complete the cleaning action under the drive of water flow and automatically disengage:

[0062] After the sewage flows into the sewage pipe 91, its impact force pushes the cleaning mechanism 96 to move synchronously along the slide bar 93 and the inner wall of the sewage pipe 91. During the movement, the cleaning mechanism 96 always stays in contact with the pipe wall to complete the scraping and cleaning of impurities and scale.

[0063] As the cleaning mechanism 96 moves toward the outlet of the sewage pipe 91, it first comes into contact with the moving cylinder 972, which in turn pushes the fixed frame 973 to move synchronously.

[0064] When the fixed frame 2 973 moves, it drives the moving cylinder 972 to move axially along the sewage pipe 91;

[0065] The moving cylinder 972 simultaneously pulls the round shaft 971 and the second spring 974 sleeved on the round shaft 971;

[0066] Finally, the cleaning mechanism 96, the fixed frame 2 973, and the moving cylinder 972 detach from the inside of the sewage pipe 91. At this time, there is no obstruction inside the sewage pipe 91, and the sewage can flow out smoothly, avoiding interference of the cleaning mechanism 96 with the sewage flow rate.

[0067] Once the sewage discharge is complete, the mechanism automatically resets using the elastic force of the second spring 974, preparing for the next sewage discharge and cleaning operation.

[0068] After the sewage stops being discharged, the impact force of the sewage on the cleaning mechanism 96 is reduced. When the impact force is less than the tensile rebound force of the second spring 974;

[0069] The second spring 974 releases its stored force, pulling the cleaning mechanism 96 to move inward toward the drain pipe 91; as the cleaning mechanism 96 moves, its squeezing force on the fixed frame 973 and the moving cylinder 972 gradually decreases.

[0070] The rebound force of the second spring 974 synchronously drives the moving cylinder 972 to move along the circular shaft 971 to the initial position. The fixed frame 973 and the cleaning mechanism 96 follow the moving cylinder 972 back to their original positions and finally return to the sewage pipe 91, waiting to start cleaning when the sewage is discharged next time.

[0071] Please see Figure 7 The cleaning mechanism 96 includes a guide component 961, a scraping component 963 is fixedly connected to one side of the guide component 961, and a contact component 962 is fixedly connected to the other side of the guide component 961.

[0072] When sewage enters the sewage pipe 91, it will have a direct impact on the contact component 962, guide component 961 and scraping component 963 inside the pipe;

[0073] Under the impact force, the guide component 961 moves axially along the preset slide bar 93. During the movement, the guide component 961 always keeps in contact with the inside of the sewage pipe 91. Through the guide of the slide bar 93, stable guiding movement is achieved, ensuring that the sewage pipe 91 moves in the axial direction without deviating.

[0074] At the same time, the contact component 962 and the scraping component 963 are also driven by the impact force of sewage to simultaneously contact the inside of the sewage pipe 91 and move in the direction of movement of the guide component 961, while cleaning the inside of the sewage pipe 91.

[0075] Please see Figure 8 The scraping assembly 963 includes a scraping housing 9631, a guide plate 9632 fixedly connected to the side of the scraping housing 9631, a connecting shaft 9633 slidably connected to the inner side of the scraping housing 9631, a connecting plate 9634 fixedly connected to the other end of the connecting shaft 9633, a scraper 9635 fixedly connected to the side of the connecting plate 9634 away from the connecting shaft 9633, and a third spring 9636 sleeved on the connecting shaft 9633. One end of the third spring 9636 is fixedly connected to the connecting plate 9634, and the other end of the third spring 9636 is fixedly connected to the inner side of the scraping housing 9631.

[0076] When the guide housing 9611 moves axially along the slide bar 93, it will synchronously drive the scraper housing 9631 connected to it, so that the scraper housing 9631 moves stably together with the guide housing 9611 in the drain pipe 91. With the guidance of the guide housing 9611, the scraper housing 9631 is prevented from deflecting due to water flow impact.

[0077] When the sewage passes through the sewage pipe 91, the impact force will cause the guide plate 9632 on the scraping shell 9631 to rotate, and at the same time the guide plate 9632 will cause the scraping shell 9631 to rotate on the guide shell 9611.

[0078] At the same time, the connecting shaft 9633 moves inside the scraping housing 9631, and at the same time, the connecting plate 9634 drives the scraper 9635 to move towards the inner wall of the drain pipe 91, while pulling the third spring 9636 sleeved on the connecting shaft 9633.

[0079] This causes the scraper 9635 to rotate and come into contact with the inner wall of the drain pipe 91, scraping away scale, impurities, and other debris adhering to the pipe wall.

[0080] Please see Figure 9The guide assembly 961 includes a guide housing 9611. One side of the guide housing 9611 is rotatably connected to the side of the scraping housing 9631 away from the guide plate 9632. The other side of the guide housing 9611 is fixedly connected to the side of the contact frame 9621. The inner sides of the guide housing 9611, the scraping housing 9631, and the contact frame 9621 are all slidably connected to the side of the slide rod 93. A sliding shaft 9612 is fixedly connected to the inner side of the guide housing 9611. The side of the sliding shaft 9612 is slidably connected to the inner side of the slide groove 94. The inner side of the guide housing 9611 is uniformly provided with round rods 9613. One end of the round rod 9613 is slidably connected to the inner side of the guide housing 9611. The other end of the round rod 9613 is fixedly connected to a bracket 9614. The side of the bracket 9614 away from the round rod 9613 is rotatably connected to a guide wheel 9615. A fourth spring 9616 is sleeved on the round rod 9613. One end of the fourth spring 9616 is fixedly connected to the bracket 9614. The other end of the fourth spring 9616 is fixedly connected to the inner side of the guide housing 9611.

[0081] When sewage enters the sewage pipe 91, it causes the guide housing 9611 to slide on the slide rod 93;

[0082] At the same time, the sliding shaft 9612 inside the guide housing 9611 will move synchronously in the groove 94 in the middle of the slide rod 93. Through the cooperation of the slide rod 93 and the groove 94, the sliding direction of the guide housing 9611 is restricted, and it is prevented from deviating during movement.

[0083] When the guide housing 9611 slides, the fourth spring 9616 pushes the bracket 9614 toward the inner wall of the drain pipe 91 by its own elastic force, thereby causing the guide wheel 9615 on the inner side of the bracket 9614 to contact the inner wall of the drain pipe 91 to form a guide.

[0084] When the guide housing 9611 slides along the slide bar 93, the guide wheel 9615 rolls synchronously along the inner wall of the drain pipe 91 to avoid shaking during movement and ensure the smoothness of the guide movement.

[0085] When it moves to the bend of the drain pipe 91, the curvature of the inner wall of the drain pipe 91 changes, and at this time the fourth spring 9616 will achieve adaptive adjustment through elastic deformation.

[0086] If the distance between the inner wall at the bend and the guide wheel 9615 becomes smaller, the spring will be compressed, causing the bracket 9614 to retract slightly, thus preventing the guide wheel 9615 from excessively squeezing the pipe wall.

[0087] If the gap increases, the spring will extend and push the bracket 9614 to move outward, ensuring that the guide wheel 9615 is always in contact with the inner wall of the drain pipe 91;

[0088] Please see Figure 10The contact assembly 962 includes a contact frame 9621. The side of the contact frame 9621 away from the guide housing 9611 is fixedly connected to the end of the second spring 974 away from the fixed frame 92. Both sides of the contact frame 9621 are slidably connected to contact shafts 9622. The other end of the contact shaft 9622 is fixedly connected to a contact plate 9623. A fifth spring 9624 is sleeved on the contact shaft 9622. One end of the fifth spring 9624 is fixedly connected to the inner side of the contact frame 9621, and the other end of the fifth spring 9624 is fixedly connected to the contact plate 9623.

[0089] When sewage enters the sewage pipe 91, the guide housing 9611 moves and simultaneously drives the contact frame 9621 to move together with it inside the sewage pipe 91.

[0090] The contact plate 9623 moves against the pipe wall contact frame 9621 via the contact shaft 9622 and the fifth spring 9624, ultimately achieving contact and movement cleaning with the pipe wall;

[0091] Because the fifth spring 9624 has elastic buffering capability, when the contact plate 9623 encounters hard impurities attached to the pipe wall, the fifth spring 9624 will be compressed, and the deformation will absorb the excess contact force, avoiding excessive squeezing force between the contact plate 9623 and the impurities, thereby preventing the inner wall of the drain pipe 91 from being scratched.

[0092] Specific workflow:

[0093] When the steam pressure in boiler shell 1 exceeds the specified value, safety valve 6 automatically opens to reduce the pressure by releasing steam; when the pressure drops to the safe specified value, safety valve 6 automatically closes to prevent the pressure from continuing to drop and affecting the normal operation of boiler shell 1, without the need for manual intervention throughout the process.

[0094] When the water level in boiler shell 1 reaches the "high water level" or "low water level" threshold, the water level alarm will immediately issue an audible and visual alarm, and automatically shut down the boiler through the control cabinet to remind the operator to pay attention to the abnormal water level.

[0095] The water level gauge 8 and water level alarm are installed on the side of the cylinder 1, allowing operators to directly observe water level changes without disassembling parts, making it intuitive and convenient.

[0096] The sampling tube seat 11 facilitates the periodic extraction of boiler water samples to test water hardness, pH and other indicators, providing a basis for scale removal and water treatment.

[0097] The handhole device 13 is positioned low and is easy to disassemble and inspect the internal structure, without affecting the component layout when the cylinder 1 is operating normally;

[0098] After the furnace is shut down, the handhole device 13 and manhole device 4 can be opened, and the operator can enter or reach in tools to clean the scale inside the cylinder 1, inspect the inner wall, and repair the components.

[0099] During the operation of the boiler shell 1, the sewage and impurities at the bottom of the shell 1 can be discharged periodically by operating the sewage discharge component 9 to reduce scale buildup and avoid a decrease in heating efficiency and corrosion of the furnace shell 121 and inner furnace shell 122.
