Description

Technical Field

[0001] The present invention relates to the technical field of hot water boilers, and particularly relates to a load-adjustable electrode hot water boiler. Background Art

[0002] An electrode hot water boiler is a device that uses the resistance between electrodes and water to generate heat to heat water, and has a wide range of applications in many fields. The basic working principle of an electrode hot water boiler is based on the resistance characteristics of water. When the electrodes are inserted into the water and the power is turned on, the current passes through the water. Since water has a certain resistance, heat is generated when the current flows through the water. By controlling the voltage and current of the electrodes, the generated heat can be accurately adjusted, so as to achieve the purpose of heating water.

[0003] In the patent document with the authorization announcement number CN113865081B, an electrode boiler with automatic descaling is disclosed, including: a furnace body with a water inlet and a water outlet, a zero-position electrode located in the furnace body and in a cylindrical shape, a phase electrode coaxially arranged inside the zero-position electrode, and a driving mechanism, wherein: an insulating sleeve coaxial with the two is arranged between the zero-position electrode and the phase electrode, the insulating sleeve is connected to the driving mechanism and can move up and down under the drive of the driving mechanism, and an inner cleaning ring fixedly arranged coaxially with it is arranged inside the insulating sleeve; the phase electrode is located inside the inner cleaning ring, and the insulating sleeve forms an isolation between the phase electrode and the zero-position electrode. The driving mechanism drives the insulating sleeve to move up and down, so that by moving the insulating sleeve up and down, the contact area between the phase electrode and the zero-position electrode is adjusted, and thus the purpose of adjusting the power is achieved. This kind of adjustment has a fast response, sensitive action, and can achieve stepless adjustment. At the same time, by arranging an inner cleaning ring inside the insulating sleeve, the surface of the phase electrode is cleaned when the insulating sleeve moves up and down, thereby avoiding the normal operation of the phase electrode being affected due to scale formation on its surface.

[0004] However, there are still the following problems in this solution. The end face of the phase electrode is an arc surface, and the inner cleaning ring cannot cover the end face of the phase electrode when cleaning the phase electrode, so the cleaning of the phase electrode cannot be comprehensively covered. The scale covering the end face of the phase electrode will cause uneven heat distribution on its surface, resulting in too high temperature in local areas, affecting the heating efficiency, accelerating the aging and damage of the phase electrode, and the inner cleaning ring always adheres to its surface during the operation of the phase electrode, which will also block the phase electrode, causing the same negative effects as the scale, and is not conducive to the normal operation of the phase electrode. Summary of the Invention

[0005] The present invention provides a load-adjustable electrode hot water boiler, aiming to solve the problem that the end face of the phase electrode cannot be covered when cleaning the phase electrode in the related technology, and the cleaning of the phase electrode cannot be comprehensively covered.

[0006] The load-adjustable electrode hot water boiler of the present invention includes a drum, a zero electrode cylinder, a phase electrode, and a water distributor. There are three zero electrode cylinders evenly distributed in a ring inside the drum. The phase electrode is coaxially arranged inside the zero electrode cylinder. The water distributor is located directly below the zero electrode cylinder. A cylindrical isolation shield is slidably assembled outside the water distributor, and the isolation shield can rotate and lift relative to the water distributor and can be sleeved outside the phase electrode during rising to isolate the ion migration between the phase electrode and the zero electrode cylinder.

[0007] A vertical plate and an arc plate are arranged at the top of the isolation shield. The vertical plate can slide along the radial direction of the isolation shield to be close to or away from the surface of the phase electrode. The arc plate is rotatably arranged at the end of the vertical plate and can be attached to the arc end face of the phase electrode as the isolation shield moves.

[0008] Preferably, a support and a base located below the support are fixedly installed inside the drum. The zero electrode cylinder is fixedly installed on the support, and the water distributor is arranged on the base.

[0009] Preferably, a bracket is arranged above the base, and a hoop is arranged on the bracket. The isolation shield is rotatably assembled in the hoop.

[0010] Preferably, a lead screw is rotatably assembled inside the base. The bottom end of the lead screw extends outside the drum and is provided with a servo motor. A nut is fixedly installed inside the bracket, and the nut is threadedly connected to the outside of the lead screw.

[0011] Preferably, a turntable is rotatably assembled outside the water distributor. A telescopic rod is fixedly installed at the top of the turntable, and the telescopic end of the telescopic rod is fixedly connected to the isolation shield. A gear ring is fixedly installed outside the turntable, and a gear meshing with the gear ring is fixedly installed on the outside of the lead screw.

[0012] Preferably, a support block is fixedly installed at the top of the isolation shield. A cross bar is slidably arranged inside the support block, and the cross bar is horizontally arranged along the radial direction of the isolation shield. An installation plate is fixedly installed on the cross bar on one side of the support block. A spring is arranged between the installation plate and the support block, and the spring is in a compressed state. The vertical plate is fixedly installed at the end of the cross bar, and a torsion spring is arranged between the vertical plate and the arc plate to apply a torsional force to the arc plate in the direction of the phase electrode.

[0013] Preferably, an annular plate is slidably assembled along the height direction outside the isolation shield. A cylinder for driving its lifting is arranged at the bottom of the annular plate. A wedge plate is fixedly installed at the top of the annular plate, and the side of the wedge plate away from the isolation shield is an inclined surface. A transverse groove is opened along the length direction inside the cross bar, and the top end of the wedge plate slides in the transverse groove.

[0014] Preferably, an electrode socket is fixedly installed at the top of the drum. A hollow electrode porcelain sleeve is fixedly installed inside the electrode socket. The phase electrode is fixedly installed at the bottom end of the electrode porcelain sleeve. A bergamot wire clamp is arranged at the top end of the electrode porcelain sleeve, and a conductive copper bar is arranged between the bergamot wire clamp and the phase electrode.

[0015] Preferably, a convex ring seat located inside the electrode socket is arranged outside the electrode porcelain sleeve. Sealing rings are arranged on both the upper and lower sides of the convex ring seat.

[0016] Preferably, an upper insulating sheath is arranged at the bottom of the electrode socket, and a lower insulating sheath is arranged at the top of the water distributor.

[0017] Beneficial effects:

[0018] 1. When the present invention is in use, by the rotation and lifting of the isolation shield, the blocking area between the zero electrode cylinder and the phase electrode is adjusted to achieve the adjustment of the boiler load. The vertical plate and the arc plate cooperate with each other to comprehensively clean the side and end faces of the phase electrode during the lifting of the isolation shield, effectively preventing scale from condensing and accumulating on the surface of the phase electrode, enabling the phase electrode to maintain a good conductive heating effect, extending the service life of the phase electrode. Moreover, during rotation, the vertical plate and the arc plate can form a vortex in the electrolyte aqueous solution in the zero electrode cylinder, enabling the removed scale to quickly separate from the phase electrode, the vertical plate, and the arc plate, and then be discharged together with the electrolyte aqueous solution, avoiding the accumulation of scale at the contact parts of the vertical plate, the arc plate, and the phase electrode after the scale is scraped off.

[0019] 2. When the present invention is in use, by the lifting of the wedge plate, the cross bar can be pushed to slide in the support block, enabling the vertical plate to move away when the phase electrode does not need to be cleaned, avoiding large-area shielding of the phase electrode by the vertical plate during the operation of the phase electrode, making the heat on the surface of the phase electrode evenly distributed, and maintaining a good working state.

[0020] 3. When the present invention is in use, the spherical arc surface of the sealing ring contacts the convex ring seat to achieve spherical sealing between the convex ring seat and the sealing ring, thereby reducing friction and having stronger anti-wear performance, enabling the sealing ring to better adapt to harsh environments such as high pressure and high temperature, and enabling the sealing ring to be applicable to different angular spans. The electrode porcelain sleeve can be flexibly adjusted in angle during assembly and ensure the sealing performance. Description of the drawings

The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] As Figures 1 to 10 ​​​​As shown in the figure, the load-adjustable electrode hot water boiler of the present invention includes a boiler drum 10, a zero electrode drum 11, a phase electrode 12, a water distributor 13, an isolation power adjustment assembly 20, a driving mechanism 30, a transmission mechanism 40, a cleaning mechanism 50, and a pushing mechanism 60. The zero electrode drum 11 and the phase electrode 12 are correspondingly arranged inside the boiler drum 10 for heating the electrolyte aqueous solution. The water distributor 13 is located below the zero electrode drum 11 for dispersedly transporting the electrolyte aqueous solution. The isolation power adjustment assembly 20 is arranged below the zero electrode drum 11 and can adjust the boiler load under the drive of the driving mechanism 30. The cleaning mechanism 50 is arranged on the isolation power adjustment assembly 20 and can clean the scale outside the phase electrode 12 under the action of the transmission mechanism 40 and can move away from the phase electrode 12 under the action of the pushing mechanism 60.

[0035] Reference Figure 4 、 Figure 6 、 Figure 7 and Figure 9 , a support 14 and a base 15 are fixedly installed inside the boiler drum 10. The support 14 is located in the middle part of the boiler drum 10, and the base 15 is located inside the lower end head of the boiler drum 10. The zero electrode drum 11 is fixedly installed on the support 14. There are three zero electrode drums 11 and they are evenly distributed in a ring. An electrode socket 16 is arranged at the top of the boiler drum 10. An electrode insulation device 70 is arranged inside the electrode socket 16. The phase electrode 12 is hoisted in the middle of the zero electrode drum 11 through the electrode insulation device 70. The water distributor 13 is arranged on the base 15, and there are three water distributors 13 correspondingly arranged directly below the three zero electrode drums 11. An inlet pipe and a blowdown port are arranged at the bottom of the boiler drum 10, and an outlet pipe is arranged at the top of the boiler drum 10, so that the electrolyte aqueous solution enters from the bottom of the boiler drum 10 and is discharged from the top for circulation.

[0036] The base 15 is circular, and a water discharge connecting pipe 151 and a cone 152 are arranged on the base 15.

[0037] There are multiple water discharge connecting pipes 151 evenly distributed in a circle at the bottom of the base 15, connecting the upper and lower sides of the base 15, so that the electrolyte aqueous solution in the boiler drum 10 can enter the bottom through the water discharge connecting pipe 151 and then be discharged from the blowdown port at the bottom of the boiler drum 10. At the same time, the water discharge connecting pipe 151 can also play a role in supporting the base 15.

[0038] The cone 152 is arranged directly above the water inlet at the bottom of the boiler drum 10 with the tip facing downwards, which can effectively disperse the water inlet impact force to a larger area, reduce the impact of the water inlet on the flat plate, and further protect the structural stability.

[0039] An upper insulation sheath 17 is arranged at the bottom of the electrode socket 16, and a lower insulation sheath 18 is arranged at the top of the water distributor 13. Both the upper insulation sheath 17 and the lower insulation sheath 18 are made of polytetrafluoroethylene insulation material, which can insulate and isolate and extend the water current path.

[0040] Reference Figure 4 、 Figure 7 and Figure 8 As shown in FIGS. Figure 4 , Figure 7 and Figure 8 , the isolation power regulation assembly 20 includes a bracket 21, an isolation shield 22 and a hoop 23. The bracket 21 is located above the base 15. There are three isolation shields 22, all of which are cylindrical. The isolation shields 22 are rotationally assembled on the bracket 21 through the hoop 23. The three isolation shields 22 are respectively sleeved outside the three water distributors 13 and can move up and down relative to the water distributors 13, so that the top ends of the isolation shields 22 extend into the zero electrode cylinder 11 and are sleeved outside the phase electrode 12 to isolate between the zero electrode cylinder 11 and the phase electrode 12 and adjust the load of the boiler.

[0041] Reference Figure 4 、 Figure 7 and Figure 8 The drive mechanism 30 includes a servo motor 31, a lead screw 32 and a nut 33. The servo motor 31 is fixedly installed at the bottom of the boiler drum 10. The lead screw 32 is rotationally assembled between the boiler drum 10 and the base 15. The bottom end of the lead screw 32 is connected to the servo motor 31 through a coupling. The nut 33 is threadedly connected to the lead screw 32 and fixed to the bracket 21. The servo motor 31 can drive the lead screw 32 to rotate, push the nut 33 to move up and down to drive the bracket 21 and the isolation shield 22 to move up and down, and adjust the height of the isolation shield 22.

[0042] Reference Figure 6 and Figure 7 The transmission mechanism 40 includes a turntable 41, a telescopic rod 42, a gear ring 43 and a gear 44. The turntable 41 is rotationally assembled outside the water distributor 13. The telescopic rod 42 is fixedly installed on the top of the turntable 41, and the telescopic end of the telescopic rod 42 is fixedly connected to the isolation shield 22. The turntable 41 can drive the isolation shield 22 to rotate without affecting its lifting. The gear ring 43 is fixedly installed on the turntable 41, and the gear 44 is fixedly installed on the lead screw 32 and meshes with the gear ring 43. When the lead screw 32 pushes the isolation shield 22 to move up and down, the gear 44 can be driven to rotate to push the gear ring 43 to drive the turntable 41 to rotate, so that the isolation shield 22 can rotate while lifting, so that the cleaning mechanism 50 can clean the phase electrode 12.

[0043] Reference Figure 9 and Figure 10, the cleaning mechanism 50 includes a support block 51, a cross bar 52 and a scraper 53. The support block 51 is fixedly installed at the top of the isolation shield 22. The cross bar 52 is horizontally slidably arranged in the support block 51 along the radial direction of the isolation shield 22. The scraper 53 is arranged at the end of the cross bar 52 and is close to the phase electrode 12, and can scrape the scale adhered to the outside of the phase electrode 12 during the rotation and lifting of the isolation shield 22, so that the scale can be discharged outside the boiler drum 10 as the electrolyte aqueous solution moves. An installation plate 521 is fixedly installed on the cross bar 52 on one side of the support block 51. A spring 522 is arranged between the installation plate 521 and the support block 51, and the spring 522 is in a compressed state, applying a thrust force to the installation plate 521 in the direction of the phase electrode 12, so that the scraper 53 can closely adhere to the side wall of the phase electrode 12.

[0044] The scraper 53 is composed of a vertical plate 531 and an arc plate 532. The vertical plate 531 is fixedly installed at the end of the cross bar 52, and the surface of the vertical plate 531 close to the phase electrode 12 is an arc surface, so that the vertical plate 531 can closely adhere to the side of the phase electrode 12, and then better clean the side of the phase electrode 12. There are two arc plates 532 respectively rotatably assembled at the upper and lower ends of the vertical plate 531. The two arc plates 532 respectively match the radian of the upper and lower end faces of the phase electrode 12, and a torsion spring is arranged between the arc plate 532 and the vertical plate 531, which can apply a torsional force to the arc plate 532 in the direction of the phase electrode 12, so that when the arc plate 532 moves to the end of the phase electrode 12, it can rotate and adhere to the arc end face of the phase electrode 12 under the push of the torsion spring to complete the cleaning of the arc end face of the phase electrode 12.

[0045] Reference Figure 9 And Figure 10 , the pushing mechanism 60 includes an annular plate 61, a cylinder 62 and a wedge plate 63. The annular plate 61 slides up and down outside the isolation shield 22. The cylinder 62 is arranged at the bottom of the annular plate 61 and is fixed to the isolation shield 22. The wedge plate 63 is fixedly installed at the top of the annular plate 61. One side of the wedge plate 63 away from the isolation shield 22 is an inclined surface, and its width gradually increases from top to bottom. A transverse groove 523 is opened in the cross bar 52 along its length direction. The top end of the wedge plate 63 is arranged in the transverse groove 523. When the cylinder 62 pushes the annular plate 61 to rise and the wedge plate 63 slides in the transverse groove 523, the cross bar 52 can be pushed by the wedge plate 63 to slide in the support block 51, so that the vertical plate 531 is far away from the phase electrode 12, reducing the contact area between the cleaning mechanism 50 and the phase electrode 12 and avoiding affecting the work done on the phase electrode 12.

[0046] Reference Figure 4 And Figure 9, the electrode insulation device 70 consists of a conductive copper rod 71, an electrode porcelain bushing 72, a bergamot wire clamp 73, and a sealing assembly 74. The electrode porcelain bushing 72 is vertically fixed on the electrode socket 16 through a flange. The bottom end of the electrode porcelain bushing 72 extends into the drum 10. The phase electrode 12 is fixedly installed at the bottom end of the electrode porcelain bushing 72. The bergamot wire clamp 73 is arranged at the top end of the electrode porcelain bushing 72 and is used to connect the high-voltage incoming cable. The conductive copper rod 71 penetrates through the inside of the electrode porcelain bushing 72, and its upper and lower ends are respectively fixed to the bergamot wire clamp 73 and the phase electrode 12 to connect the bergamot wire clamp 73 and the phase electrode 12. The sealing assembly 74 is located between the electrode porcelain bushing 72 and the electrode socket 16 and can seal between the electrode porcelain bushing 72 and the electrode socket 16.

[0047] The sealing assembly 74 includes a raised ring seat 741 and a sealing ring 742. The raised ring seat 741 is arranged outside the electrode porcelain bushing 72. There are two sealing rings 742 respectively arranged on the upper and lower sides of the raised ring seat 741. The surface of the sealing ring 742 close to the raised ring seat 741 is a spherical arc surface, and the surface far from the raised ring seat 741 is a plane, realizing spherical sealing between the raised ring seat 741 and the sealing ring 742. Subsequently, the friction can be reduced, and the anti-wear performance is stronger, enabling the sealing ring 742 to better adapt to harsh environments such as high voltage and high temperature, and enabling the sealing ring 742 to be applicable to different angular spans. The electrode porcelain bushing 72 can be flexibly adjusted in angle during assembly and ensure the sealing performance.

[0048] In the present invention, three-phase alternating current is introduced into the phase electrode 12 at the center of the zero electrode cylinder 11 through the electrode insulation device 70. The three zero electrode cylinders 11 are evenly distributed in the drum 10 in three equal parts along the circumferential direction. The distance from the outer surface of each phase electrode 12 to the inner wall of its respective zero electrode cylinder 11 is equal. After power-on, under the action of the electric field force, the ion migration cross-section and distance in the electrolyte aqueous solution in the zero electrode cylinder 11 are equal, the heating is uniform, the three-phase load is equal, and the three-phase balance degree is high. Moreover, the three zero electrode cylinders 11 form a whole, and together with the phase electrode 12 and the electrolyte aqueous solution, a current loop is formed after power-on. The zero electrode cylinder 11 is the common neutral point for the electrode to work, forming a Y-type connection method, which can perfectly adapt to the input alternating current;

[0049] The driving mechanism 30 drives the isolation shield 22 to move up and down to block the current channel between the isolation zero electrode cylinder 11 and the phase electrode 12. As the isolation shield 22 rises, the blocking area between the zero electrode cylinder 11 and the phase electrode 12 increases, extending the current path, and then reducing the power load during boiler heating; as the isolation shield 22 descends, the blocking area between the zero electrode cylinder 11 and the phase electrode 12 decreases, shortening the current path, and then increasing the power load during boiler heating, realizing the adjustment of the boiler load;

[0050] During the lifting of the isolation shield 22, under the action of the spring 522, the vertical plate 531 closely adheres to the side wall of the phase electrode 12, and can clean the scale on the surface of the phase electrode 12. The end of the arc-shaped plate 532 is blocked by the phase electrode 12, and then rotates in the vertical plate 531 to compress the torsion spring, so that the torsion spring maintains the torsional force on the arc-shaped plate 532. The transmission mechanism 40 drives the isolation shield 22 to rotate itself during the lifting and lowering of the isolation shield 22, enabling the vertical plate 531 to rotate around the phase electrode 12 and clean its circumference, increasing the cleaning area. When the vertical plate 531 moves to the end of the phase electrode 12, the arc-shaped plate 532 automatically adheres to the arc-shaped end face of the phase electrode 12 under the action of the torsion spring and moves along with the rotating vertical plate 531 to clean the end face of the phase electrode 12, ensuring the thorough cleaning of the scale on the surface of the phase electrode 12. At the same time, when the vertical plate 531 and the arc-shaped plate 532 rotate, they can stir the electrolyte aqueous solution in the zero electrode cylinder 11 to form a vortex, and then wash the scale on the vertical plate 531 and the arc-shaped plate 532, so that the scale can be quickly separated after being cleaned from the phase electrode 12, facilitating the better discharge of the scale along with the electrolyte aqueous solution, and effectively avoiding the large accumulation of scale outside the phase electrode 12 to form a scale layer;

[0051] By raising the wedge-shaped plate 63, the push rod 52 is pushed to move in the support block 51, which can make the vertical plate 531 away from the surface of the phase electrode 12, and can avoid the vertical plate 531 blocking the phase electrode 12 during the use of the boiler, ensuring the uniformity of the work done by the phase electrode 12. When the phase electrode 12 needs to be cleaned, the wedge-shaped plate 63 is lowered to contact the push force on the push rod 52, and the vertical plate 531 can automatically adhere to the surface of the phase electrode 12 under the action of the spring 522, facilitating the cleaning of the scale.

[0052] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations of the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
