Description

Technical Field

[0001] This invention relates to the field of steam electrode boiler technology, and more specifically to a high-pressure steam electrode boiler with high heating efficiency. Background Technology

[0002] A high-pressure steam electrode boiler is a device that uses a high-voltage power supply to heat water and provide steam or hot water. The working principle of a high-pressure steam electrode boiler is to use the high thermal resistance of water to convert electrical energy into heat energy and generate steam by passing electricity through it.

[0003] Existing high-pressure steam electrode boilers include an outer furnace body, an inner furnace body, and electrode rods. Water is first introduced into the outer furnace body, and then the water inside the outer furnace body is transported to the inner furnace body by a circulation pump. The water is directly heated by the electrode rods located inside the inner furnace body. The water level in the outer furnace body can be controlled by the circulation pump, thereby controlling the water level submerged in the electrode rods and achieving control of the electrode rod output power.

[0004] The shortcomings of existing high-pressure steam electrode boilers are as follows: Although existing electrode boilers directly heat water to generate steam by passing electricity through electrode rods, achieving high heating efficiency, the heating process of water by the electrode rods using high-voltage electricity does not involve simultaneous heating at different depths throughout the water source; rather, the heat gradually diffuses and increases in temperature. That is, water molecules near the electrode rods are first affected by the heat, beginning to heat up and convert into heat energy. As heat is continuously generated and accumulated, this heat energy gradually diffuses to other parts of the water source, causing the overall water temperature to gradually rise. However, this process takes time, resulting in insufficient heating efficiency. Although agitators can be used to directly stir the water in the furnace, continuous stirring causes significant water flow impact on the electrode rods, easily affecting their lifespan. Furthermore, after prolonged use, scale easily forms on the surface of the electrode rods, which also affects heating efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a high-pressure steam electrode boiler with high heating efficiency, so as to solve the technical problem that in the prior art, when the electrode rod of the steam electrode boiler heats water, the heat can only gradually diffuse to a distance, which takes a certain amount of time, resulting in insufficient heating efficiency.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

[0007] A high-pressure steam electrode boiler with high heating efficiency includes an outer furnace body, an inner furnace body, and electrode rods. The electrode rods are fixedly installed on the inner side of the inner furnace body, and a steam discharge pipe communicating with the inner furnace body is installed on the top of the outer furnace body. It also includes:

[0008] The piston-type reciprocating water delivery mechanism has two sets, which are distributed inside the inner furnace body and symmetrically distributed on both sides of the electrode rod. A partition plate is fixedly connected to the outer furnace body near the top. A drive mechanism for driving the piston-type reciprocating water delivery mechanism to slide back and forth is installed on the partition plate. The reciprocating water delivery mechanism is used to draw water from the inner side of the inner furnace body away from the electrode rod and deliver the water to the position close to the electrode rod.

[0009] The lifting scraper mechanism is used to clean the surface of the electrode rod. The lifting scraper mechanism is slidably mounted on the electrode rod and moves up and down along the electrode rod as the piston-type reciprocating water delivery mechanism slides back and forth.

[0010] As a further aspect of the present invention: each set of piston-type reciprocating water supply mechanisms includes a piston cylinder, a piston plate, and a suction pipe. The piston cylinder is connected to the drive mechanism, and the piston plate is slidably connected inside the piston cylinder. The piston cylinder has multiple suction holes that communicate with the internal space of the piston cylinder at equal intervals on the side away from the electrode rod. Each suction hole is connected to a set of suction pipes. Each suction hole is equipped with a one-way valve for water inlet. The bottom of the piston cylinder is equipped with a water spray device facing the electrode rod, and the water spray device is equipped with a one-way valve for water outlet. The side of the piston cylinder near the electrode rod is equipped with a linkage horizontal plate that is fixedly connected to the piston plate. A first limiting block is fixedly connected to the inner wall of the inner furnace body near the electrode rod, and a second limiting block is fixedly connected to the inner wall of the inner furnace body away from the electrode rod. The end of the linkage horizontal plate is positioned between the first limiting block and the second limiting block.

[0011] As a further embodiment of the present invention: the inlet one-way valve includes a mounting ring and a first one-way valve plate. The mounting ring is fixedly connected inside the suction hole, and the first one-way valve plate is attached to the side of the mounting ring near the inside of the piston cylinder. The first one-way valve plate is movably connected to the mounting ring via a spring-loaded hinge.

[0012] As a further aspect of the present invention: the water spray component includes a water outlet, a transition cylinder, and a spray pipe. The water outlet is located on the side of the piston cylinder away from the electrode rod. The transition cylinder is fixedly connected to the outer wall of the piston cylinder and covers the location of the water outlet. The spray pipe is connected to the bottom of the transition cylinder, and the end of the spray pipe faces the location of the electrode rod.

[0013] As a further aspect of the present invention: the water outlet one-way valve includes a second one-way valve plate, the second one-way valve plate is attached to the outer side of the end of the nozzle, and one side of the second one-way valve plate is movably connected to the nozzle through a spring-loaded hinge.

[0014] As a further aspect of the present invention: each set of suction tubes includes a swing tube, a rotating support, and a buoyancy sealing mechanism. The swing tube is rotatably mounted on the outer wall of the piston cylinder via the rotating support and is connected to the corresponding suction hole by an elastic hose. The swing tube is tilted to one side, and the buoyancy sealing mechanism is fitted at the end of the swing tube to seal the end of the swing tube. The swing tubes of two adjacent sets of suction tubes have opposite tilting directions.

[0015] As a further embodiment of the present invention: the rotating support includes a support plate, the support plate is fixedly connected to the outer wall of the piston cylinder, a connecting shaft is rotatably connected to the support plate, and the end of the swing tube near the piston cylinder is fixedly connected to the connecting shaft, and a disc spring is connected between the connecting shaft and the support plate.

[0016] As a further embodiment of the present invention: the buoyancy sealing mechanism includes a float, a guide rod, and a sealing plate. The float is disposed above the end of the oscillating tube. The guide rod passes vertically through the float and is fixedly connected to the corresponding oscillating tube. The sealing plate is fixedly connected to one side of the float and cooperates with the port of the oscillating tube.

[0017] As a further embodiment of the present invention: the driving mechanism includes an electric telescopic rod, a linkage rod, and a strip-shaped sliding opening. The electric telescopic rod is fixedly connected to the partition plate. Two linkage rods are provided and are respectively movably connected to the telescopic end of the electric telescopic rod via hinges. Two strip-shaped sliding openings are provided and are symmetrically opened on the partition plate. An extension sliding rod is fixedly connected to the top of the piston cylinder and passes through the corresponding strip-shaped sliding opening. The extension sliding rod is also slidably connected to the corresponding strip-shaped sliding opening. The end of the linkage rod is movably connected to the extension sliding rod via a hinge. A closed sliding plate that is fixedly connected to the extension sliding rod is slidably attached to the strip-shaped sliding opening.

[0018] As a further embodiment of the present invention: the lifting scraper ring mechanism includes a cleaning ring, an insulating traction rope, and a steering guide wheel. The cleaning ring is slidably sleeved on the electrode rod. The cleaning ring includes an outer ring and an annular brush body connecting the inner ring of the outer ring. One end of the insulating traction rope is fixedly connected to the corresponding piston cylinder, and the other end is fixedly connected to the cleaning ring. The steering guide wheel is rotatably set at the top position of the inner furnace body, and the insulating traction rope passes around the steering guide wheel.

[0019] The beneficial effects of this invention are:

[0020] 1. This invention relies on an electric telescopic rod and a linkage rod drive combination to make the piston cylinder distributed in the inner furnace body continuously move closer to or away from the electrode rod. Whenever the piston cylinder moves away from the electrode rod, the linkage horizontal plate and the second limiting block cooperate to make the piston plate move relative to the piston cylinder, thereby drawing water from the position inside the inner furnace body away from the electrode rod. Whenever the piston cylinder moves closer to the electrode rod, the linkage horizontal plate and the first limiting block cooperate to make the piston plate move in the opposite direction relative to the piston cylinder, thereby pressurizing the drawn water and spraying it towards the position near the electrode rod. In this way, water away from the electrode rod can be continuously transported to the position near the electrode rod, so that more water molecules come into contact with the electrode rod in a shorter time, which helps to accelerate the heat transfer speed and make the water heat up faster, thereby improving the heating efficiency. Moreover, the piston cylinder adopts a reciprocating motion to draw and deliver water, realizing intermittent water delivery, thus ensuring that the water delivered in each interval can be effectively heated for a certain period of time.

[0021] 2. In this invention, whenever the piston cylinder moves away from the electrode rod and approaches the edge of the inner furnace body, the end of the swing tube set on one side of the piston cylinder suction hole is squeezed against the inner wall of the inner furnace body. Since the swing tube is set to one side, it can be deflected during the squeezing process. During this process, the suction hole is drawing water. This makes it convenient to deflect the swing tube through different angle positions to draw water from multiple different directions, thereby increasing the range of water drawing and making it easier to send multiple water positions away from the electrode rod to the vicinity of the electrode rod for heating, thus improving heating efficiency.

[0022] 3. The piston cylinder of this invention has multiple swing tubes distributed longitudinally. Each swing tube has a sealing plate and a float at its end. The floats corresponding to the swing tubes submerged in water will float up due to buoyancy, thereby causing the sealing plates to rise, which facilitates the opening of the corresponding swing tubes and the pumping of water. The floats corresponding to the swing tubes not submerged in water are at the lowest position due to gravity, and the corresponding sealing plates seal the ports of the swing tubes, which can effectively prevent the pumping of air or the generation of steam. In other words, the swing tubes at the corresponding positions can be automatically opened according to the water level.

[0023] 4. During the reciprocating motion of the piston cylinder of this invention, the cleaning ring is pulled up and down by the cooperation of the insulated traction rope and the steering guide wheel, which facilitates the longitudinal movement of the cleaning ring along the electrode rod, thereby cleaning the surface of the electrode rod to a certain extent, reducing the formation of scale, and thus avoiding affecting the heating efficiency.

Detailed Implementation

[0037] 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.

[0038] like Figures 1-11 As shown, a high-pressure steam electrode boiler with high heating efficiency includes an outer furnace body 1, an inner furnace body 5, and electrode rods 30. The inner furnace body 5 is fixed inside the outer furnace body 1, and there is a space between them. The electrode rods 30 are fixedly installed inside the inner furnace body 5. The inner furnace body 5 is insulated. Due to the gap between the inner furnace body 5 and the outer furnace body 1, it can prevent the outer furnace body 1 from being accidentally energized when the electrode rods 30 are energized, thus preventing danger. A water inlet pipe 3 is fixedly installed on one side of the bottom of the outer furnace body 1. The water inlet pipe 3 is connected to a pump element to deliver external water to the space between the outer furnace body 1 and the inner furnace body 5. A circulation pump 2 is also installed at the bottom of the outer furnace body 1. The water inlet of the circulation pump 2 is connected to the space between the outer furnace body 1 and the inner furnace body 5. A circulation water pipe 6 is installed in the middle of the bottom of the inner furnace body 5. Furthermore, the end of the circulating water pipe 6 furthest from the inner furnace body 5 is connected to the outlet of the circulating pump 2. Water is sent into the space between the outer furnace body 1 and the inner furnace body 5 through the inlet pipe 3. Then, the circulating pump 2 pumps the water between the outer furnace body 1 and the inner furnace body 5 into the inner furnace body 5. The water is directly heated by the electrode rod 30 through high voltage electricity. The depth of the electrode rod 30 immersed in the water can be controlled by controlling the circulating pump 2 to draw water from the inner furnace body 5. This can increase the output power of the boiler. At the same time, the water between the outer furnace body 1 and the inner furnace body 5 can also absorb the heat lost from the inner furnace body 5 to a certain extent, preventing the heat from being directly lost. A steam exhaust pipe 4 connected to the inner furnace body 5 is installed on the top of the outer furnace body 1. The steam exhaust pipe 4 is used to discharge the steam generated in the inner furnace body 5 and can be connected to an external pipeline for steam transportation.

[0039] The boiler also includes a piston-type reciprocating water supply mechanism and a lifting scraper ring mechanism for cleaning the surface of the electrode rod 30. There are two sets of piston-type reciprocating water supply mechanisms, which are distributed inside the inner furnace body 5 and symmetrically distributed on both sides of the electrode rod 30. A partition plate 9 is fixedly connected to the outer furnace body 1 near the top. The partition plate 9 creates a certain space between the top of the inner furnace body 5 and the top of the outer furnace body 1. This allows the installation of a drive mechanism on the partition plate 9 to drive the piston-type reciprocating water supply mechanism to slide back and forth inside the inner furnace body 5, facilitating the movement of moving away from and towards the electrode rod 30. The reciprocating water supply mechanism is used to draw water from the inner side of the inner furnace body 5 away from the electrode rod 30 and deliver the water to the position close to the electrode rod 30. This allows the water in the inner furnace body 5 away from the electrode rod 30 to quickly come into contact with the electrode rod 30 and then be heated. This allows more water molecules to come into contact with the electrode rod 30 in a shorter time, which helps to accelerate the heat transfer speed and make the water heat up faster, thereby improving the heating efficiency.

[0040] The lifting scraper mechanism is slidably mounted on the electrode rod 30, and moves up and down along the electrode rod 30 as the piston-type reciprocating water supply mechanism slides back and forth, making it easy to scrape off the deposits attached to the surface of the electrode rod 30, reducing the formation of scale, thus preventing scale and other substances from affecting the heating efficiency.

[0041] In some specific implementation plans, combined with Figure 3 , Figure 7 and Figure 8 As shown, each set of piston-type reciprocating water supply mechanisms includes a piston cylinder 7, a piston plate 21, and suction pipe fittings. The piston cylinder 7 is a cuboid and is longitudinally located inside the inner furnace body 5, with a relatively long vertical length. The inner furnace body 5 is also a cuboid. The piston cylinder 7 reciprocates along the longer direction of the inner furnace body 5. The piston cylinder 7 is connected to the drive mechanism. The piston plate 21 is slidably connected inside the piston cylinder 7. The side of the piston cylinder 7 closest to the electrode rod 30 is open. The side of the piston cylinder 7 away from the electrode rod 30 has multiple suction holes 22 that communicate with the internal space of the piston cylinder 7 at equal intervals. Each suction hole 22 is connected to a set of suction pipe fittings. Each suction hole 22 is equipped with a one-way valve for water inlet. The piston cylinder 7 has a water spray component at its bottom facing the electrode rod 30, and the water spray component is equipped with a one-way valve for water outlet. The piston cylinder 7 has a linkage horizontal plate 14 fixedly connected to the piston plate 21 via a rod on the side near the electrode rod 30. A first limiting block 16 is fixedly connected to the inner wall of the inner furnace body 5 near the electrode rod 30, and a second limiting block 15 is fixedly connected to the inner wall of the inner furnace body 5 away from the electrode rod 30. The end of the linkage horizontal plate 14 is positioned between the first limiting block 16 and the second limiting block 15. It should be noted that, in order to facilitate the force balance when the linkage horizontal plate 14 is pressed, the first limiting block 16 and the second limiting block 15 are both distributed in pairs on the inner walls of both sides of the inner furnace body 5.

[0042] When the piston cylinder 7 is close to the electrode rod 30, the linkage horizontal plate 14 presses against the first limiting block 16. At this time, the piston plate 21 connected to the linkage horizontal plate 14 is at the innermost side of the piston cylinder 7, close to the suction hole 22. When the drive mechanism drives the piston cylinder 7 to move laterally away from the electrode rod 30, the piston cylinder 7 moves synchronously with the linkage horizontal plate 14. When the piston cylinder 7 is close to the edge of the inner furnace body 5, the linkage horizontal plate 14 is blocked by the second limiting block 15 and cannot move forward. At this time, the relative movement of the piston cylinder 7 will cause the piston plate 21 connected to the linkage horizontal plate 14 to slide relative to the internal space of the piston cylinder 7, so that the suction hole 22 can suck water at the edge of the inner furnace body 5 away from the electrode rod 30 by the suction pipe. Then the drive mechanism drives the piston cylinder 7 to slide back close to the electrode rod 30. When the linkage horizontal plate 14 is pressed against the first limiting block 16 again and cannot move forward, the advancing piston cylinder 7 will cause the piston plate 21 to slide relative to the electrode rod 30. The piston cylinder 7 slides and squeezes the previously drawn water inside the space. Due to the presence of the one-way valve in the suction hole 22, the squeezed water can only be sprayed onto the electrode rod 30 through the water spraying component. This achieves the accelerated transport of water from the inner furnace body 5 away from the electrode rod 30 to the vicinity of the electrode rod 30 for heating. Then the piston cylinder 7 moves away from the electrode rod 30 again, and so on. Compared with the continuous stirring of the water in the inner furnace body 5 by the stirring component, the reciprocating motion of the piston cylinder 7 can generate a relatively small water flow impact force, thereby reducing the impact on the electrode rod 30 and avoiding affecting the service life of the electrode rod 30. At the same time, after the piston cylinder 7 delivers a certain amount of water to the vicinity of the electrode rod 30 each time, some water can remain near the electrode rod 30 for a period of time, which is convenient for heating for a period of time. This avoids the water flow speed being too fast, which may cause the heat to be carried away before it can be fully transferred, affecting the heating efficiency. This ensures that the piston cylinder 7 delivers water to the vicinity of the electrode rod 30 at an appropriate reciprocating motion speed.

[0043] In some specific implementation plans, such as Figure 9 As shown, the inlet one-way valve includes a mounting ring 27 and a first one-way valve plate 28. The mounting ring 27 is fixedly connected inside the suction hole 22. The first one-way valve plate 28 is attached to the side of the mounting ring 27 near the inside of the piston cylinder 7, that is, the diameter of the first one-way valve plate 28 is larger than the inner diameter of the mounting ring 27. One side of the first one-way valve plate 28 is movably connected to the mounting ring 27 through a spring-loaded hinge. When the piston plate 21 squeezes the water inside the piston cylinder 7 in the direction of the suction hole 22, the first one-way valve plate 28 is subjected to hydraulic pressure and will only stick tightly to the mounting ring 27 and cannot open. Therefore, the squeezed water will only be discharged from the spray nozzle. The piston plate 21 slides away from the suction hole 22. When the piston cylinder 7 is sucked, water can enter the suction hole 22 from the outside and push open the first one-way valve plate 28 to enter the inside of the piston cylinder 7.

[0044] In some specific implementation plans, such as Figure 8As shown, the water spray component includes a water outlet 23, a transition cylinder 24, and a spray pipe 25. The water outlet 23 is located at the bottom of the piston cylinder 7 on the side away from the electrode rod 30, and there are multiple water outlets 23. The transition cylinder 24 is fixedly connected to the outer wall of the piston cylinder 7 and covers the location of the water outlet 23, that is, the transition cylinder 24 is connected to the water outlet 23. The spray pipe 25 is connected to the bottom of the transition cylinder 24, and the end of the spray pipe 25 faces the location of the electrode rod 30.

[0045] In some specific implementations, the water outlet one-way valve includes a second one-way valve plate 26. The second one-way valve plate 26 is attached to the outer side of the end of the nozzle 25, that is, the diameter of the second one-way valve plate 26 is larger than the inner diameter of the nozzle 25, and one side of the second one-way valve plate 26 is movably connected to the nozzle 25 through a spring-loaded hinge. When the piston plate 21 squeezes the water in the piston cylinder 7, the water can enter the transition cylinder 24 through the water outlet 23, and then be sprayed outward through the nozzle 25, thus opening the second one-way valve plate 26. When the piston cylinder 7 draws water, the second one-way valve plate 26 is attached to the outer side of the end of the nozzle 25 to achieve a seal, so that water cannot enter from the nozzle 25.

[0046] In some other specific implementations, the outlet check valve can also be installed inside the outlet hole 23, and the outlet check valve has the same structure as the inlet check valve, except that the position of the check valve plate is reversed.

[0047] In some specific implementation plans, such as Figure 7 As shown, each set of suction tubes includes a swing tube 8, a rotating support, and a buoyancy sealing mechanism. The swing tube 8 is rotatably mounted on the outer wall of the piston cylinder 7 via the rotating support, and is connected to the corresponding suction hole 22 by an elastic hose. The elastic hose connects the swing tube 8 and the corresponding suction hole 22, and has a certain degree of elasticity, allowing it to stretch and deform during the deflection of the swing tube 8, causing it to tilt to one side. The buoyancy sealing mechanism is located at the end of the swing tube 8 to seal its end. It should be noted that the swing tubes 8 of adjacent sets of suction tubes tilt in opposite directions. For details, please refer to [reference needed]. Figure 6 As shown.

[0048] The rotating support includes a support plate 33, which is fixedly connected to the outer wall of the piston cylinder 7. A connecting shaft is rotatably connected to the support plate 33, and the end of the swing tube 8 near the piston cylinder 7 is fixedly connected to the connecting shaft. A coil spring is connected between the connecting shaft and the support plate 33. The swing tube 8 can rotate and swing relative to the support plate 33 and the piston cylinder 7 by relying on the connecting shaft, and the coil spring can be tightened to generate a rebound force, which facilitates the swing tube 8 to rotate and reset after swinging.

[0049] When the piston cylinder 7 moves laterally closer to the inner wall of the inner furnace body 5 away from the electrode rod 30, the distributed swing tubes 8 also approach the inner wall of the inner furnace body 5. When the linkage horizontal plate 14 abuts against the second limit stop 15, the ends of the swing tubes 8 are also pressed against the inner wall of the inner furnace body 5. Since the swing tubes 8 distributed on both sides of the piston cylinder 7 are inclined to the corresponding sides, as the piston cylinder 7 continues to move forward, it will compress the distributed swing tubes 8, causing the ends of the swing tubes 8 on both sides to deflect to the corresponding sides along the inner wall of the inner furnace body 5, specifically as follows: Figure 11 As shown, at the same time, since the piston plate 21 slides relative to the piston cylinder 7, the suction hole 22 produces a suction effect. In this way, water can be drawn from the inner furnace body 5 away from the electrode rod 30 by relying on the swing tube 8 which rotates and deflects to both sides. Furthermore, due to the swing of the swing tube 8, it is convenient to draw water from multiple positions away from the electrode rod 30, thereby increasing the suction range, and then transporting it to the vicinity of the electrode rod 30.

[0050] In other specific implementations, to facilitate the end of the oscillating tube 8 pressing against the inner wall of the inner furnace body 5 or sliding along the inner wall of the inner furnace body 5, thereby achieving the deflection of the oscillating tube 8, each end of the oscillating tube 8 is rotatably connected to a roller 20 via a rotating shaft. See reference for details. Figure 4 When the end of the oscillating tube 8 approaches the inner wall of the inner furnace body 5, the roller 20 abuts against the inner wall of the inner furnace body 5, making it easy to roll along the inner wall of the inner furnace body 5, thus facilitating the deflection of the oscillating tube 8.

[0051] In some specific implementation plans, such as Figure 4 As shown, the buoyancy sealing mechanism includes a float 18, a guide rod 19, and a sealing plate 17. The float 18 is positioned above the end of the swing tube 8 and is made of buoyancy material. The guide rod 19 vertically penetrates the float 18 and is fixedly connected to the corresponding swing tube 8. The float 18 slides longitudinally relative to the guide rod 19. A stop block can be provided at the top of the guide rod 19 to prevent the float 18 from completely detaching. The sealing plate 17 is fixedly connected to one side of the float 18 and cooperates with the port of the swing tube 8. When a certain amount of water is introduced into the inner furnace body 5, the float 18 corresponding to the swing tube 8 submerged in water rises along the corresponding guide rod 19 due to buoyancy, thereby causing the corresponding sealing plate 17 to rise, so that the port of the swing tube 8 is in an open state, facilitating water suction. For details, please refer to [reference needed]. Figure 7 As shown, the float 18 corresponding to the oscillating tube 8 that is not submerged in water is positioned at the bottom of the guide rod 19 due to gravity. At this time, the sealing plate 17 blocks the port of the oscillating tube 8, thus sealing the corresponding oscillating tube 8. For details, please refer to [reference needed]. Figure 4 As shown in the figure, this avoids the oscillating pipe 8 at this position from being empty, so that the oscillating pipe 8 at the corresponding position can be effectively pumped water according to the water level.

[0052] In some specific implementation plans, combined with Figure 3 and Figure 5As shown, the drive mechanism includes an electric telescopic rod 10, a linkage rod 11, and a strip-shaped sliding opening 13. The electric telescopic rod 10 is fixedly connected to the partition plate 9. Two linkage rods 11 are provided, and each is movably connected to the telescopic end of the electric telescopic rod 10 via hinges. Two strip-shaped sliding openings 13 are provided and symmetrically opened on the partition plate 9. The strip-shaped sliding openings 13 are through-hole type. An extension sliding rod is fixedly connected to the top of the piston cylinder 7, and the extension sliding rod passes through the corresponding strip-shaped sliding opening 13. The extension sliding rod is also slidably connected to the corresponding strip-shaped sliding opening 13. The end of the linkage rod 11 is movably connected to the extension sliding rod via a hinge. A closed sliding plate 12, which is fixedly connected to the corresponding extension sliding rod, slides against the strip-shaped sliding opening 13. The length of plate 12 is greater than that of the strip-shaped sliding opening 13. The electric telescopic rod 10 is continuously extended and retracted by the controller. During the extension and retraction process, the corresponding extension sliding rod is driven by the linkage rod 11 on both sides of the extension end to slide back and forth along the corresponding strip-shaped sliding opening 13. In this way, the piston cylinder 7 can slide back and forth in the inner furnace body 5, and the sealing plate 12 slides relative to the strip-shaped sliding opening 13. During the reciprocating sliding of the piston cylinder 7, since the length of the sealing plate 12 is greater than that of the strip-shaped sliding opening 13, within the range of the piston cylinder 7's movement stroke, no matter whether the piston cylinder 7 moves to the farthest position or the closest position to the electrode rod 30, the sealing plate 12 always covers the strip-shaped sliding opening 13 to prevent steam from flowing out through the strip-shaped sliding opening 13.

[0053] In some specific implementation plans, such as Figure 10 With two electrode rods 30, two sets of lifting scraper ring mechanisms are also required. The lifting scraper ring mechanism includes a cleaning ring 29, an insulating traction rope 32, and a steering guide wheel 31. The cleaning ring 29 is slidably fitted onto the electrode rod 30, and the entire cleaning ring 29 is made of insulating material. The cleaning ring 29 includes an outer ring and an annular brush body connecting the inner ring of the outer ring. One end of the insulating traction rope 32 is fixedly connected to the corresponding piston cylinder 7, and the other end is fixedly connected to the cleaning ring 29. The steering guide wheel 31 is rotatably mounted at the top of the inner furnace body 5 via a bracket, and the steering guide wheel 31 is close to the electrode rod 30. The insulating traction rope 32 rotates from the top of the inner furnace body 5. The guide wheel 31 is used to guide the cleaning ring 29 to move closer to the bottom of the electrode rod 30 when the piston cylinder 7 is close to the electrode rod 30 due to gravity. When the piston cylinder 7 moves away from the electrode rod 30, the piston cylinder 7 pulls the insulating traction rope 32. The insulating traction rope 32 then pulls the cleaning ring 29 to slide and rise along the electrode rod 30 by the steering action of the guide wheel 31. When the piston cylinder 7 moves closer to the electrode rod 30 again, the insulating traction rope 32 will loosen, causing the cleaning ring 29 to fall due to gravity. This process is repeated, so that the cleaning ring 29 can clean the surface of the electrode rod 30 and reduce the formation of scale.

[0054] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0055] First, water is introduced between the outer furnace body 1 and the inner furnace body 5 through the water inlet pipe 3. Then, the water between the outer furnace body 1 and the inner furnace body 5 is pumped into the inner furnace body 5 by the circulation pump 2. The water is directly heated by the electrode rod 30 through high voltage electricity. The depth of the electrode rod 30 immersed in the water can be controlled by controlling the circulation pump 2 to draw water from the inner furnace body 5.

[0056] During the heating process, the electric telescopic rod 10 is continuously extended and retracted by the controller. During the extension and retraction of the electric telescopic rod 10, the corresponding extension slide rod is driven by the linkage rod 11 on both sides of the extension end to slide back and forth along the corresponding strip slide 13. In this way, the piston cylinder 7 can slide back and forth in the inner furnace body 5, and the sealing slide plate 12 slides relative to the strip slide 13. During the reciprocating sliding of the piston cylinder 7, since the length of the sealing slide plate 12 is greater than the length of the strip slide 13, within the range of the piston cylinder 7's movement stroke, no matter whether the piston cylinder 7 moves to the farthest position or the closest position to the electrode rod 30, the sealing slide plate 12 always covers the strip slide 13 to prevent steam from flowing out through the strip slide 13.

[0057] During the reciprocating motion of the piston cylinder 7, the piston cylinder 7 continuously approaches or moves away from the electrode rod 30. Whenever the piston cylinder 7 is close to the electrode rod 30, the linkage horizontal plate 14 presses against the first limiting block 16. At this time, the piston plate 21 connected to the linkage horizontal plate 14 is located at the innermost side of the piston cylinder 7, close to the suction hole 22. When the piston cylinder 7 moves laterally away from the electrode rod 30, the piston cylinder 7 moves synchronously with the linkage horizontal plate 14. When the piston cylinder 7 is close to the edge of the inner furnace body 5, the linkage horizontal plate 14 is blocked by the second limiting block 15 and cannot move forward. At this time, the moving piston cylinder 7 separates from the linkage horizontal plate 14, causing the piston plate 21 to slide relative to the internal space of the piston cylinder 7. This allows the suction hole 22 to draw water from the edge of the inner furnace body 5 away from the electrode rod 30 by the swing tube 8. Then, the piston cylinder 7 slides back close to the electrode rod 30. When the linkage horizontal plate 14 is pressed against the first limiting block 16 again and cannot move forward, the piston plate 21 slides relative to the internal space of the piston cylinder 7, squeezing the previously drawn water. A one-way valve is installed inside the suction hole 22, preventing water from passing through it. The squeezed water can only enter the transition cylinder 24 through the outlet hole 23, and then be sprayed outward through the nozzle 25, opening the second one-way valve plate 26 and spraying it towards the electrode rod 30. This achieves the accelerated transport of water from the inner furnace body 5 away from the electrode rod 30 to the vicinity of the electrode rod 30 for heating. Then the piston cylinder 7 moves away from the electrode rod 30 again, and so on. Compared with the continuous stirring of water in the inner furnace body 5 by the stirring element, the reciprocating motion of the piston cylinder 7 can generate a relatively small water flow impact force, thereby reducing the impact on the electrode rod 30 and avoiding affecting the service life of the electrode rod 30. At the same time, when the piston cylinder 7 transports a certain amount of water to the vicinity of the electrode rod 30 and then slides away again, some of the transported water can stay near the electrode rod 30 for a period of time, which is convenient for heating for a period of time. This avoids the water flow speed being too fast, which may cause the heat to be carried away before it can be fully transferred, affecting the heating efficiency. This ensures that the piston cylinder 7 delivers water to the vicinity of the electrode rod 30 at an appropriate reciprocating motion speed.

[0058] Furthermore, when the piston cylinder 7 moves laterally closer to the inner wall of the inner furnace body 5 away from the electrode rod 30, the distributed swing tubes 8 also approach the inner wall of the inner furnace body 5. When the linkage horizontal plate 14 abuts against the second limit stop 15, the end of the swing tube 8 is also squeezed against the inner wall of the inner furnace body 5. Since the swing tubes 8 distributed on both sides of the piston cylinder 7 are inclined to the corresponding side, as the piston cylinder 7 continues to move forward, it will squeeze the distributed swing tubes 8, thereby causing the ends of the swing tubes 8 on both sides to deflect to the corresponding side along the inner wall of the inner furnace body 5. At the same time, since the piston plate 21 slides relative to the piston cylinder 7, the suction hole 22 produces a suction effect. In this way, water can be drawn from the position of the inner furnace body 5 away from the electrode rod 30 by relying on the swing tubes 8 that rotate and deflect to both sides. Moreover, due to the swing of the swing tubes 8, it is convenient to draw water from multiple positions away from the electrode rod 30, that is, increase the suction range, and then transport it to the position near the electrode rod 30.

[0059] Simultaneously, when the piston cylinder 7 is close to the electrode rod 30, the cleaning ring 29 moves closer to the bottom of the electrode rod 30 due to gravity. When the piston cylinder 7 moves away from the electrode rod 30, the piston cylinder 7 pulls the insulating traction rope 32. The insulating traction rope 32 then pulls the cleaning ring 29 to slide and rise along the electrode rod 30 by relying on the steering action of the steering guide wheel 31. When the piston cylinder 7 approaches the electrode rod 30 again, the insulating traction rope 32 will slacken, causing the cleaning ring 29 to descend due to gravity. This process is repeated, so that the cleaning ring 29 can clean the surface of the electrode rod 30 and reduce the formation of scale.

[0060] It should also be noted that when a certain amount of water is introduced into the inner furnace body 5, the float 18 corresponding to the oscillating tube 8 submerged in water rises along the corresponding guide rod 19 due to buoyancy, thereby causing the corresponding sealing plate 17 to rise, so that the port of the oscillating tube 8 is in an open state, which facilitates water suction. Meanwhile, the float 18 corresponding to the oscillating tube 8 not submerged in water is at the bottom position of the guide rod 19 due to gravity. At this time, the sealing plate 17 blocks the port of the oscillating tube 8, sealing the corresponding oscillating tube 8, thereby preventing the oscillating tube 8 at this position from sucking water without water. In this way, the oscillating tube 8 at the corresponding position can be automatically and effectively sucked water according to the water level.

[0061] The foregoing has described several embodiments of the present invention in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of the invention. All equivalent variations and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
