Description

Technical Field

[0001] The invention relates to the technical field of steam electrode boilers, and in particular to a high-pressure steam electrode boiler with high heating efficiency. Background Art

[0002] A high-pressure steam electrode boiler is a device that uses a relatively high voltage power supply for heating to 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 thermal energy and generate steam by passing electricity.

[0003] The existing high-pressure steam electrode boiler includes an outer furnace body, an inner furnace body and electrode rods. The water source is first introduced into the outer furnace body, and then the water inside the outer furnace body is transported to the inner furnace body through a circulating pump. The water is directly heated by the electrode rods inside the inner furnace body. The water level in the outer furnace body can be controlled by the circulating pump, thereby controlling the water level that immerses the electrode rods, thereby realizing the output power control of the electrode rods.

[0004] The shortcomings of the existing high-pressure steam electrode boilers are: although the existing electrode boilers can achieve high heating efficiency by directly heating water through the electrode rods to generate steam, the heat is not generated at different depths of the entire water source at the same time when the electrode rods are heated by high voltage electricity, but the heat gradually diffuses and heats up. That is, the water molecules near the electrode rods will be affected by the heat first, start to heat up and convert into thermal energy. As heat is continuously generated and accumulated, this thermal energy will gradually diffuse to other parts of the water source, causing the temperature of the entire water source to gradually increase, but this process takes a certain amount of time, which will result in insufficient heating efficiency. Although a stirring piece can be used to directly stir the water in the furnace, continuous stirring will cause the water in the furnace to produce a large water flow impact on the electrode rod, which is likely to affect the service life of the electrode rod; in addition, after the electrode rods are used for a long time, scale is likely to form on their surface, which will affect the heating efficiency. Summary of the invention

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention relies on an electric telescopic rod and a linkage rod driving combination to make the piston cylinder distributed in the inner furnace body constantly approach or move away from the electrode rod. Whenever the piston cylinder moves away from the electrode rod, the linkage horizontal plate and the second limit block cooperate with each other to make the piston plate move relative to the piston cylinder, thereby absorbing water from a position inside the inner furnace body away from the electrode rod. Whenever the piston cylinder approaches the electrode rod, the linkage horizontal plate and the first limit block cooperate with each other to make the piston plate move in the opposite direction relative to the piston cylinder, thereby pressing the sucked water out and spraying it to a position near the electrode rod. In this way, the water away from the electrode rod can be continuously transported to the position near the electrode rod, so that more water molecules can contact the electrode rod in a shorter time, which helps to speed up the heat transfer speed and make the water heat up faster, thereby improving the heating efficiency. In addition, each time the piston cylinder takes water and delivers water in a reciprocating motion to achieve intermittent water delivery, which can ensure that the water delivered in each interval can be effectively heated for a certain period of time.

[0021] 2. In the present invention, whenever the piston cylinder is away from the electrode rod and close to the edge of the inner furnace body, the end of the swing tube arranged on one side of the suction hole of the piston cylinder is squeezed onto the inner wall of the inner furnace body. Since the swing tube is arranged to one side, it can be deflected during the extrusion process. During this process, the suction hole is sucking water. In this way, the swing tube at different angles can be deflected to suck water in multiple directions, that is, the range of water suction is increased, and multiple water far away from the electrode rod can be sent to the vicinity of the electrode rod for heating, thereby improving the heating efficiency.

[0022] 3. A plurality of swing tubes are longitudinally distributed on the piston cylinder of the present invention, and a sealing piece and a floating ball are distributed at the end of each swing tube. The floating balls corresponding to the swing tubes immersed in water will float up due to the buoyancy, thereby driving the sealing piece to rise, making it convenient for the corresponding swing tubes to open and to pump water. The floating balls corresponding to the swing tubes not immersed in water are at the lowest position due to gravity, and the corresponding sealing pieces block the ports of the swing tubes, which can effectively avoid the suction of air or the generation of steam, that is, the swing tubes at the corresponding positions are automatically opened according to the water level.

[0023] 4. During the reciprocating motion of the piston cylinder of the present invention, the cleaning ring is pulled in by cooperating with the insulating traction rope and the steering guide wheel, so that the cleaning ring can move longitudinally along the electrode rod, thereby cleaning the surface of the electrode rod to a certain extent, reducing the generation of scale, and thus avoiding affecting the heating efficiency.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-Figure 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 an electrode rod 30. The inner furnace body 5 is fixed on the inner side of the outer furnace body 1, and there is a space between the two. The electrode rod 30 is fixedly installed on the inner side of the inner furnace body 5. The inner furnace body 5 is insulated. Since there is a distance between the inner furnace body 5 and the outer furnace body 1, it can prevent the electrode rod 30 from accidentally causing the outer furnace body 1 to be energized when it is energized, which may cause 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 externally connected to a pump element and is used to send external water source into between the outer furnace body 1 and the inner furnace body 5. A circulating pump 2 is also installed at the bottom of the outer furnace body 1. The water inlet end of the circulating pump 2 is connected to the space between the outer furnace body 1 and the inner furnace body 5. A circulating water pipe 6 is installed at the middle position of the bottom of the inner furnace body 5. The end of the circulating water pipe 6 away from the inner furnace body 5 is connected to the water outlet end of the circulating pump 2, and the water is sent into the space between the outer furnace body 1 and the inner furnace body 5 through the water inlet pipe 3, and 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 circulating pump 2, and the water is directly heated by the electrode rod 30 through high voltage electricity, and the depth of the electrode rod 30 immersed in the water can be controlled by controlling the circulating pump 2 to suck the water in the inner furnace body 5, so that the output power of the boiler can be controlled, and at the same time, the water between the outer furnace body 1 and the inner furnace body 5 can also absorb the heat dissipated inside 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, and 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 and scraping ring mechanism for cleaning the surface of the electrode rod 30. The piston-type reciprocating water supply mechanism is provided with two groups, 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 allows a certain space between the top of the inner furnace body 5 and the top of the outer furnace body 1. In this way, a driving mechanism for driving the piston-type reciprocating water supply mechanism to slide back and forth inside the inner furnace body 5 can be installed on the partition plate 9, which is convenient for the movement of constantly moving away from and approaching the electrode rod 30. The reciprocating water supply mechanism is used to suck water from the inner side of the inner furnace body 5 away from the electrode rod 30 and send the water to a position close to the electrode rod 30. In this way, the water in the inner furnace body 5 away from the electrode rod 30 can quickly contact the electrode rod 30 and then be heated, that is, more water molecules can contact the electrode rod 30 in a shorter time, which helps to speed up the heat transfer speed and make the water heat up faster, thereby improving the heating efficiency;

[0040] The lifting scraper ring mechanism is slidably set on the electrode rod 30, and the lifting scraper ring mechanism moves up and down along the electrode rod 30 as the piston-type reciprocating water supply mechanism slides back and forth, which is convenient for scraping off the attachments attached to the surface of the electrode rod 30 and reducing the generation of scale. This can prevent scale and other substances from affecting the heating efficiency.

[0041] In some specific embodiments, in combination Figure 3 , Figure 7 and Figure 8 As shown, each group of piston-type reciprocating water supply mechanisms includes a piston cylinder 7, a piston plate 21 and a suction pipe. The piston cylinder 7 is a rectangular parallelepiped and is longitudinally arranged on the inner side of the inner furnace body 5. The vertical length is relatively long. At the same time, the inner furnace body 5 is also a rectangular parallelepiped. The piston cylinder 7 reciprocates along the longer direction of the inner furnace body 5. The piston cylinder 7 is connected with the driving mechanism. The piston plate 21 is slidably connected inside the piston cylinder 7. The side of the piston cylinder 7 close to the electrode rod 30 is open. The side of the piston cylinder 7 away from the electrode rod 30 is longitudinally equidistantly provided with a plurality of suction holes 22 connected to the internal space of the piston cylinder 7. Each suction hole 22 is correspondingly connected with a group of suction pipes, and each suction hole 22 is provided with a water inlet check valve. A water spraying member facing the electrode rod 30 is arranged at the bottom of the piston cylinder 7, and the water spraying member is provided with a water outlet one-way valve member. A linkage horizontal plate 14 fixedly connected to the piston plate 21 through a rod body is arranged on the side of the piston cylinder 7 close to the electrode rod 30. A first limit block 16 is fixedly connected to the inner wall of the inner furnace body 5 close to the electrode rod 30, and a second limit 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 fitted between the first limit block 16 and the second limit block 15. It should be noted that in order to facilitate the force balance when the linkage horizontal plate 14 is squeezed, the first limit block 16 and the second limit block 15 are distributed in pairs on the inner walls on both sides of the inner furnace body 5.

[0042] When the piston cylinder 7 is close to the electrode rod 30, the linkage cross plate 14 is squeezed on the first limit stopper 16. At this time, the piston plate 21 connected to the linkage cross plate 14 is at the innermost side of the piston cylinder 7, close to the position of the suction hole 22. When the driving mechanism drives the piston cylinder 7 to move laterally away from the electrode rod 30, the piston cylinder 7 moves synchronously with the linkage cross plate 14. When the piston cylinder 7 is close to the edge of the inner furnace body 5, the linkage cross plate 14 is blocked by the second limit stopper 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 cross plate 14 to slide relative to the internal space of the piston cylinder 7, so that the suction hole 22 relies on the suction pipe to suck water at the edge of the inner furnace body 5 away from the electrode rod 30. Then the driving mechanism drives the piston cylinder 7 to slide back close to the electrode rod 30. When the linkage cross plate 14 is squeezed on the first limit stopper 16 again and cannot move forward, the advancing piston cylinder 7 will cause the piston plate 21 to The piston cylinder 7 slides and squeezes the previously sucked water in the internal space. Due to the presence of the water inlet one-way valve in the suction hole 22, the squeezed water can only be sprayed toward the electrode rod 30 through the water spraying member, that is, the water in the inner furnace body 5 away from the electrode rod 30 is accelerated and transported to the vicinity of the electrode rod 30 for heating, and then the piston cylinder 7 is away from the electrode rod 30 again, and this is repeated. Compared with the continuous stirring of the water in the inner furnace body 5 directly through the stirring member, the reciprocating motion of the piston cylinder 7 to transport water can relatively generate a smaller 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 transports a certain amount of water to the vicinity of the electrode rod 30 each time, part of the water can also stay in the vicinity of the electrode rod 30 for a period of time, which is convenient for heating for a period of time, avoiding the water flow speed being too fast, which may cause the heat to be taken away before it can be fully transferred, affecting the heating efficiency, that is, the piston cylinder 7 delivers water to the vicinity of the electrode rod 30 at a suitable reciprocating speed.

[0043] In some specific embodiments, such as Fig. 9 As shown, the water inlet one-way valve component includes a mounting ring 27 and a first one-way valve plate 28. The mounting ring 27 is fixedly connected in the suction hole 22. The first one-way valve plate 28 is fitted on the side of the mounting ring 27 close to 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, and one side of the first one-way valve plate 28 is movably connected to the mounting ring 27 through a rebound hinge. When the piston plate 21 squeezes the water inside the piston cylinder 7 toward the direction of the suction hole 22, the first one-way valve plate 28 is subjected to the hydraulic pressure and will only cling to the mounting ring 27 and cannot be opened. Therefore, the squeezed water at this time will only be discharged from the water spraying part, and 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 flush the first one-way valve plate 28 to enter the inside of the piston cylinder 7.

[0044] In some specific embodiments, such as Figure 8As shown, the water spraying member includes a water outlet hole 23, a transition tube 24 and a nozzle 25. The water outlet hole 23 is opened at the bottom of the piston cylinder 7 away from the electrode rod 30, and there are multiple water outlet holes 23. The transition tube 24 is fixedly connected to the outer wall of the piston cylinder 7 and covers the position of the water outlet hole 23, that is, the transition tube 24 is connected to the water outlet hole 23, and the nozzle 25 is connected to the bottom of the transition tube 24, and the end of the nozzle 25 faces the position of the electrode rod 30.

[0045] In some specific embodiments, the water outlet one-way valve member includes a second one-way valve plate 26, which 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 rebound 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 hole 23, and then be sprayed outward through the nozzle 25, and flush the second one-way valve plate 26. When the piston cylinder 7 sucks water, the second one-way valve plate 26 is attached to the outer side of the end of the nozzle 25 to achieve closure, so that water cannot enter from the nozzle 25.

[0046] In some other specific implementation schemes, the water outlet one-way valve member may also be installed inside the water outlet hole 23, and the water outlet one-way valve member has the same structure as the water inlet one-way valve member, except that the position of the one-way valve plate is opposite.

[0047] In some specific embodiments, such as Figure 7 As shown, each group of suction pipe fittings includes a swing pipe 8, a rotating support and a buoyancy blocking mechanism. The swing pipe 8 is rotatably arranged on the outer wall of the piston cylinder 7 through the rotating support, and an elastic hose is connected between the swing pipe 8 and the corresponding suction hole 22. The elastic hose connects the swing pipe 8 and the corresponding suction hole 22, and the elastic hose has a certain elasticity. It can be stretched and deformed during the deflection of the swing pipe 8. The swing pipe 8 tilts to one side, and the buoyancy blocking mechanism is cooperatively arranged at the end of the swing pipe 8 to block the end of the swing pipe 8. It should be noted that the swing pipes 8 of the two adjacent groups of suction pipe fittings have opposite inclination directions. For details, please refer to Figure 6 shown.

[0048] Among them, the rotating support member 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 close to the piston cylinder 7 is fixedly connected to the connecting shaft. A disc spring is cooperatively 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 disc spring can be tightened to generate a rebound force, so that the swing tube 8 can rotate and reset after swinging.

[0049] When the piston cylinder 7 moves laterally close to the inner wall of the inner furnace body 5 away from the electrode rod 30, the distributed swing tube 8 approaches the inner wall of the inner furnace body 5. When the linkage horizontal plate 14 contacts the second limit stopper 15, the end of the swing tube 8 is also squeezed onto 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 respectively, when the piston cylinder 7 continues to move forward, the distributed swing tubes 8 will be squeezed, thereby 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. Fig.11 As shown, at the same time, because the piston plate 21 slides relative to the piston cylinder 7, the suction hole 22 produces a suction effect, so that water can be sucked from the position of the inner furnace body 5 away from the electrode rod 30 by relying on the swing tube 8 that rotates and deflects to both sides, and because the swing tube 8 swings, it is convenient to suck water from multiple positions away from the electrode rod 30, that is, to increase the suction range, and then transport it to the position near the electrode rod 30.

[0050] In other specific implementation schemes, in order to facilitate the end of the swing tube 8 to be squeezed to the inner wall of the inner furnace body 5 and slide along the inner wall of the inner furnace body 5, thereby realizing the deflection of the swing tube 8, the end of each swing tube 8 is rotatably connected to a roller 20 through a rotating shaft. For details, please refer to Figure 4 When the end of the swing tube 8 is close to the inner wall of the inner furnace body 5, the roller 20 contacts the inner wall of the inner furnace body 5, making it easy to roll along the inner wall of the inner furnace body 5, thereby facilitating the deflection of the swing tube 8.

[0051] In some specific embodiments, such as Figure 4 As shown, the buoyancy plugging mechanism includes a float 18, a guide rod 19 and a plugging piece 17. The float 18 is arranged above the end of the swing tube 8. The float 18 is made of buoyancy material. The guide rod 19 vertically penetrates the float 18, and the guide rod 19 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 set on the top of the guide rod 19 to prevent the float 18 from completely falling off. The plugging piece 17 is fixedly connected to one side of the float 18, and the plugging piece 17 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 immersed in the water rises along the corresponding guide rod 19 due to the buoyancy, thereby driving the corresponding plugging piece 17 to rise, so that the port of the swing tube 8 is in an open state, which is convenient for pumping water. For details, please refer to Figure 7 As shown, the floating ball 18 corresponding to the swing pipe 8 not immersed in water is at the bottom position of the guide rod 19 due to gravity. At this time, the blocking piece 17 blocks the port of the swing pipe 8 and blocks the corresponding swing pipe 8. For details, please refer to Figure 4 The state shown in the figure can avoid empty suction of the swing pipe 8 at this position, so that the swing pipe 8 at the corresponding position can automatically and effectively pump water according to the water level.

[0052] In some specific embodiments, in combination Figure 3 and Figure 5As shown, the driving mechanism includes an electric telescopic rod 10, a linkage rod 11 and a strip slide 13. The electric telescopic rod 10 is fixedly connected to the partition plate 9. Two linkage rods 11 are provided, and are respectively movably connected to the telescopic ends of the electric telescopic rod 10 through hinges. Two strip slides 13 are provided and symmetrically opened on the partition plate 9. The strip slide 13 is a through-type, and an extension slide rod is fixedly connected to the top of the piston cylinder 7, and the extension slide rod passes through the corresponding strip slide 13. The extension slide rod is also slidably connected with the corresponding strip slide 13. The end of the linkage rod 11 is movably connected to the extension slide rod through a hinge. A closed slide 12 fixedly connected to the corresponding extension slide rod is slidably fitted on the strip slide 13, and the closed slide The length of the plate 12 is greater than the strip sliding opening 13, and the electric telescopic rod 10 is continuously extended and retracted under the control of a controller. During the extension and retraction process, the corresponding extension sliding rod is driven by the linkage rods 11 on both sides of the telescopic end to slide back and forth along the corresponding strip sliding opening 13, so that the piston cylinder 7 can be driven to slide back and forth in the inner furnace body 5, and the closed slide plate 12 slides relative to the strip sliding opening 13. During the reciprocating sliding process of the piston cylinder 7, since the length of the closed slide plate 12 is greater than the length of the strip sliding opening 13, within the moving stroke range of the piston cylinder 7, no matter the piston cylinder 7 moves to the farthest position or the closest position from the electrode rod 30, the closed slide plate 12 always covers the strip sliding opening 13 to prevent steam from flowing out through the strip sliding opening 13.

[0053] In some specific embodiments, such as Fig.10 In the case where there are two electrode rods 30, two groups of lifting and scraping ring mechanisms are naturally required. The lifting and scraping ring mechanisms include a cleaning ring 29, an insulating traction rope 32 and a steering guide wheel 31. The cleaning ring 29 is slidably sleeved on the electrode rod 30, and the cleaning ring 29 is made of insulating material as a whole. The cleaning ring 29 includes an outer ring and an annular brush body connected to 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 arranged at the top position of the inner furnace body 5 through a bracket, and the steering guide wheel 31 is close to the electrode rod 30. The insulating traction rope 32 is rotated from the rotating The cleaning ring 29 is wound around the guide wheel 31. When the piston cylinder 7 is close to the electrode rod 30, the cleaning ring 29 is close to the bottom of the electrode rod 30 due to gravity. When the piston cylinder 7 is away from the electrode rod 30, the piston cylinder 7 pulls the insulating traction rope 32. The insulating traction rope 32 relies on the steering action of the steering guide wheel 31 to pull the cleaning ring 29 to slide and rise along the electrode rod 30. When the piston cylinder 7 is close to the electrode rod 30 again, the insulating traction rope 32 will relax, so that the cleaning ring 29 will descend by gravity. This process is repeated, and the surface of the electrode rod 30 can be cleaned by the cleaning ring 29 to reduce the generation of scale.

[0054] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0055] First, water is sent into the space between the outer furnace body 1 and the inner furnace body 5 through the water inlet pipe 3, and 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, and 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 suck the water in the inner furnace body 5.

[0056] During the heating process, the electric telescopic rod 10 is continuously extended and retracted through the controller. During the extension and retraction process of the electric telescopic rod 10, the linkage rods 11 on both sides of the telescopic end drive the corresponding extension slide rods to slide back and forth along the corresponding strip slide 13, so that the piston cylinder 7 can be driven to slide back and forth in the inner furnace body 5, and the closing slide plate 12 slides relative to the strip slide 13. During the reciprocating sliding of the piston cylinder 7, since the length of the closing slide plate 12 is greater than the length of the strip slide 13, within the moving stroke range of the piston cylinder 7, no matter the piston cylinder 7 moves to the farthest position or the closest position from the electrode rod 30, the closing 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 is squeezed on the first limit stopper 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 position of 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 limit stopper 15 and cannot move forward. At this time, the piston cylinder 7 that keeps moving separates from the linkage horizontal plate 14, causing the piston plate 21 to slide relative to the internal space of the piston cylinder 7, so that the suction hole 22 relies on the swing tube 8 to suck water at the edge of the inner furnace body 5 away from the electrode rod 30. Then the piston cylinder 7 slides back to approach the electrode rod 30. When the linkage horizontal plate 14 is squeezed on the first limit stopper 16 again and cannot move forward, the piston plate 21 slides relative to the internal space of the piston cylinder 7 to squeeze the previously sucked water. A water inlet one-way valve is provided in the suction hole 22, so that water cannot pass through the suction hole 22. The squeezed water can only enter the transition cylinder 24 through the water outlet hole 23, and then spray outward through the nozzle 25, and break the second one-way valve plate 26 to spray toward the electrode rod 30, that is, the water in the inner furnace body 5 away from the electrode rod 30 is accelerated and transported to the vicinity of the electrode rod 30 for heating, and then the piston cylinder 7 is away from the electrode rod 30 again, and this is repeated. Compared with the continuous stirring of the water in the inner furnace body 5 directly through the stirring member, the reciprocating motion of the piston cylinder 7 to transport water can relatively generate a smaller 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, each time the piston cylinder 7 transports a certain amount of water to the vicinity of the electrode rod 30 and then slides away again, part of the transported water can also stay near the electrode rod 30 for a period of time, which is convenient for heating for a period of time, avoiding that the water flow speed is too fast, which may cause the heat to be taken away before it can be fully transferred, affecting the heating efficiency, that is, the piston cylinder 7 delivers water to the vicinity of the electrode rod 30 at a suitable reciprocating speed.

[0058] And when the piston cylinder 7 moves laterally close to the inner wall of the inner furnace body 5 away from the electrode rod 30, the distributed swing tube 8 approaches the inner wall of the inner furnace body 5, and when the linkage horizontal plate 14 abuts against the second limit stopper 15, the end of the swing tube 8 is also squeezed onto the inner wall of the inner furnace body 5. Since the swing tubes 8 distributed on both sides of the piston cylinder 7 are respectively inclined to the corresponding sides, the distributed swing tubes 8 will be squeezed when the piston cylinder 7 continues to move forward, thereby 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. At the same time, since the piston plate 21 slides relative to the piston cylinder 7 at this time, the suction hole 22 produces a suction effect, so that water can be sucked from the position of the inner furnace body 5 away from the electrode rod 30 by relying on the swing tube 8 that rotates and deflects to both sides, and since the swing tube 8 swings, it is convenient to suck water from multiple positions away from the electrode rod 30, that is, to increase the suction range, and then transport it to the position near the electrode rod 30.

[0059] At the same time, when the piston cylinder 7 is close to the electrode rod 30, the cleaning ring 29 is close 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 relies on the steering action of the steering guide wheel 31 to pull the cleaning ring 29 to slide and rise along the electrode rod 30. When the piston cylinder 7 is close to the electrode rod 30 again, the insulating traction rope 32 will relax, so that the cleaning ring 29 will descend by gravity. This process is repeated, and the surface of the electrode rod 30 can be cleaned by the cleaning ring 29 to reduce the generation of scale.

[0060] It should also be noted that after a certain amount of water is introduced into the inner furnace body 5, the float 18 corresponding to the swing tube 8 immersed in the water rises along the corresponding guide rod 19 due to the buoyancy, thereby driving the corresponding sealing piece 17 to rise, so that the port of the swing tube 8 is in an open state, which is convenient for pumping water, and the float 18 corresponding to the swing tube 8 not immersed in the water is at the bottom position of the guide rod 19 due to the action of gravity. At this time, the sealing piece 17 blocks the port of the swing tube 8 and blocks the corresponding swing tube 8, thereby avoiding empty suction of the swing tube 8 at this position. In this way, the swing tube 8 at the corresponding position can automatically achieve effective water suction according to the water level.

[0061] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
