Description

Technical Field

[0001] This invention relates to the field of boilers, and more specifically, to a dual-circulation steam-water combined supply electrode boiler. Background Technology

[0002] An electrode boiler is a type of hot water (steam) boiler that uses electrical energy to heat feedwater to obtain specified parameters. Unlike conventional electric boilers, which use resistance wire heating elements and low-voltage power supplies, electrode boilers utilize the conductivity and resistance of water to carry current and generate heat. Their basic operating principle aligns with the requirements for high-voltage power supplies and high-power boilers. However, electrode boilers have a narrow application range, currently primarily used as start-up boilers in nuclear power plants, resulting in very limited production volumes.

[0003] Generally, electric boilers use nickel-chromium alloy wires and coated wires to heat water. Such boilers may experience energy loss during the conversion of electrical energy into heat energy, resulting in low energy efficiency. Furthermore, prolonged use may lead to oxidation of the heating elements due to high temperatures, meaning foreign matter can be adsorbed onto the heating elements such as the nickel-chromium alloy wires and coated wires, further reducing energy efficiency. Therefore, we propose an improvement: a dual-circulation steam-water combined supply electrode boiler. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-circulation steam-water combined supply electrode boiler, which solves the problem of using nickel-chromium alloy wire and coated wire to heat water. Such electric boilers may experience energy loss during the conversion of electrical energy into heat energy, resulting in low energy efficiency. Furthermore, during prolonged use, oxidation may occur due to the high temperature of the resistive element, meaning that foreign matter may be adsorbed onto the heating element, such as the nickel-chromium alloy wire and coated wire, further reducing energy efficiency.

[0005] The application is as follows:

[0006] The system includes a support frame on which a boiler is fixedly mounted. A bearing retainer is fixedly connected to the inner wall of the boiler, and a furnace cylinder is rotatably connected to the inner wall of the bearing retainer. The system also includes:

[0007] A drive mechanism, located at the bottom of the boiler, is used to drive the furnace drum to rotate;

[0008] Electrode rods are fixedly installed in the middle of the furnace cylinder to heat the water inside the furnace cylinder;

[0009] A power supply assembly, located inside the boiler, is used to supply power to the electrode rods.

[0010] The water injection pipe is fixedly installed on the top of the boiler, and one end of it is connected to a steam jacket through a diversion corrugated pipe. The steam jacket is slidably connected to the top of the furnace drum.

[0011] An opening and closing mechanism is installed inside the furnace cylinder for opening and closing the furnace cylinder;

[0012] A lifting drive mechanism is connected to the top of the boiler to drive the steam jacket to rise and fall. When the steam jacket slides upward, it engages with the opening and closing mechanism inside the furnace. When the steam jacket slides downward, it is used to adjust the pressure inside the furnace.

[0013] As a preferred technical solution of this application, the driving mechanism includes a driving motor fixedly installed on the bottom wall of the furnace cylinder. The output end of the driving motor is fixedly connected to a driving gear. A driven gear meshes with the outer wall of the driving gear. The driven gear is fixedly installed on the outer wall of the furnace cylinder. The output end of the driving motor is rotatably connected to the inner bottom wall of the furnace cylinder through a bearing. When the driving motor is working, it can drive the driving gear to rotate. When the driving gear rotates, it can mesh with the driven gear, thereby driving the furnace cylinder to rotate.

[0014] As a preferred technical solution of this application, the power supply component includes a conductive ring, and five conductive bushings are fixedly connected to the side wall of the conductive ring. The end of the electrode rod that penetrates the furnace cylinder is electrically connected to the conductive bushings through a brush. The conductive ring is connected to the conductive bushings, thereby ensuring that the electrode rod can be effectively electrically connected to the conductive bushings, thus providing continuous power to the electrode rod.

[0015] As a preferred technical solution of this application, a bearing seat is rotatably connected to the top of the electrode rod, and a scraper is fixedly connected to the side wall of the bearing seat. The scraper abuts against the electrode rod. A retaining strip is fixedly connected to the inner side wall of the water injection pipe. The bottom of the retaining strip and the top of the scraper are both triangular inclined mechanisms. When the retaining strip and the scraper come into contact, they can abut against the scraper, so that the scraper rotates to scrape off the dirt on the outer wall of the electrode rod. The retaining strip, with its bottom and the top of the scraper being triangular inclined mechanisms, can avoid creating a restriction when in contact, thereby ensuring that the retaining strip can effectively move under the scraper.

[0016] As a preferred technical solution of this application, the bottom of the water injection pipe is provided with multiple steam holes, the bottom of the inner wall of the furnace cylinder is fixedly connected with a spiral blade one, and the top of the outer wall of the furnace cylinder is fixedly connected with a spiral blade two. When the furnace cylinder rotates, it can drive the spiral blade one to rotate, thereby stirring the water in the furnace cylinder and promoting the water to contact the electrode rod evenly. When the steam is discharged through the spiral blade two, it can form a vortex.

[0017] As a preferred technical solution of this application, the opening and closing mechanism includes a fixed slide fixedly connected to the inner wall of the furnace cylinder. A pull rod is slidably connected to the inner wall of the fixed slide. A plug is fixedly connected to the bottom of the pull rod. A drain hole is opened at the bottom of the inner wall of the furnace cylinder. When the plug blocks the drain hole, it closes the drain channel of the furnace cylinder. A spring is fixedly connected to the outer wall of the pull rod. One end of the spring is fixedly connected to the fixed slide. When the pull rod slides upward, it can drive the plug to slide upward, thereby opening the drain hole and allowing hot water to be discharged. Furthermore, when the pull rod loses its squeezing force, the spring pushes the plug to slide down automatically, thereby blocking the drain hole.

[0018] As a preferred technical solution of this application, the lifting drive mechanism includes an electric push rod fixedly installed on the top of the inner wall of the boiler. The output end of the electric push rod is fixedly connected to a bracket, and one end of the bracket is fixedly connected to a support column. The support column is fixedly connected to the steam jacket. The extension and retraction of the electric push rod can drive the bracket to move. The synchronous movement of the bracket and the support column can drive the steam jacket to rise and fall.

[0019] As a preferred technical solution of this application, the side wall of the steam jacket is provided with a steam vent hole, and a rubber cone is fixedly connected to the middle of the inner side wall of the steam jacket. The rubber cone is inserted into the furnace cylinder to adjust the pressure inside the furnace cylinder. The downward sliding of the rubber cone can pressurize the furnace cylinder and reduce the rate at which the temperature inside the furnace cylinder decreases.

[0020] As a preferred technical solution of this application, a drain pipe is fixedly connected to the bottom of the boiler, and an on / off valve is fixedly connected to the outer wall of the drain pipe. A temperature sensor and a pressure relief valve are fixedly connected to the top of the boiler, and an exhaust pipe is also fixedly connected to the top of the boiler. A drain valve is provided on the side wall of the exhaust pipe. Opening the on / off valve will open the drain pipe to discharge the hot water in the boiler. The temperature sensor can monitor the temperature inside the boiler, the pressure relief valve can relieve pressure on the boiler, and the exhaust pipe can discharge steam.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In the scheme of this application:

[0023] Through the arrangement of the furnace cylinder, drive mechanism, electrode rod, water supply assembly, water injection pipe, opening and closing mechanism, and lifting drive mechanism, the electric push rod can extend and retract to drive the support column and steam jacket to slide up and down. When the steam jacket slides upward, it can abut against the pull rod, and the pull rod drives the plug to slide upward, thus opening the furnace cylinder and collecting hot water inside the boiler. When the steam jacket slides downward, it can drive the rubber cone to slide inside the furnace cylinder, thereby adjusting the pressure inside the furnace cylinder, pressurizing the furnace cylinder, and reducing the rate of cooling of the hot water inside the furnace cylinder. When the steam jacket slides downward, it can also move the clamping strip to the underside of the scraper, and when the drive motor... When the driving gear rotates, it can mesh with the driven gear, thereby driving the furnace cylinder to rotate. When the furnace cylinder rotates, the scraper can remove dirt from the outer wall of the electrode rod. Furthermore, when the furnace cylinder rotates, it can also drive the first and second spiral blades to rotate. When the first spiral blade rotates, it can drive the water to rotate, promoting heating efficiency. By generating eddies, it moves along the periphery of the furnace cylinder-shaped electrode rod. In this way, in a device constructed with the same electrode length, the cross-section between the electrodes can be maximized, thereby promoting rapid heating of the water. At the same time, steam can also be discharged through the spiral blade second to form a swirling flow. Attached Figure Description

Furthermore, the rotation of the furnace cylinder 12 also drives the first spiral blade 17 and the second spiral blade 18 to rotate. The rotation of the first spiral blade 17 drives the water to rotate, promoting heating efficiency. By generating eddies, the water moves along the periphery of the electrode rod 13 shaped like the furnace cylinder 12. This maximizes the cross-section between the electrodes in a device with the same electrode length, thereby promoting rapid water heating. At the same time, steam can be discharged through the spiral blade 18 in a swirling flow. The steam can be discharged by opening the valve on the outer wall of the exhaust pipe 114. When hot water needs to be discharged, the drain pipe 110 can be opened to discharge the hot water.
