Description

Technical Field

[0001] This application relates to the field of electrode boiler technology, and in particular to a low-voltage electrode boiler unit. Background Technology

[0002] Currently, electrode boiler units are essentially heat supply equipment that uses electricity as energy and converts water into hot water or steam through electrode heating. Their core function is to convert electrical energy into usable heat. They feature no combustion process, no exhaust emissions, thermal efficiency of over 95%, and precise control of heat output.

[0003] Existing traditional electrode boilers use 10kV integrated electrode heating.

[0004] The existing technical solutions mentioned above have the following drawbacks: traditional electrode boilers adopt an integrated structural design, and a failure of a single component will cause the entire unit to shut down, resulting in poor heating reliability. Utility Model Content

[0005] This application provides a low-voltage electrode boiler unit for inspection and maintenance without shutting down the system, thereby improving heating efficiency.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: A low-voltage electrode boiler unit includes a unit frame and multiple electrode heating modules disposed within the unit frame. The multiple electrode heating modules are disposed at one end of the unit frame via heating pipes. The multiple electrode heating modules are horizontally distributed in multiple layers. The electrode heating modules are connected to the heating pipes, and a manual valve is provided between the electrode heating modules and the heating pipes.

[0007] By adopting the above technical solution, and by setting up a unit frame, heating pipelines, electrode heating modules and manual valves, the electrode heating modules convert electrical energy into heat energy. The connection and disconnection between the electrode heating modules and the heating pipelines can be adjusted by the manual valves. When one or more electrode heating modules fail, they can be cut off by the manual valves, while the other electrode heating modules can still maintain operation, allowing for inspection and maintenance without shutting down the system, thereby improving heating efficiency.

[0008] Optionally, each of the electrode heating modules is individually connected to a heating pipeline.

[0009] By adopting the above technical solution, each of the multiple electrode heating modules is individually connected to the heating pipeline, allowing each electrode heating module to independently form a path with the heating pipeline. The heating power can be adjusted by controlling the number of electrode heating modules in operation, adapting to different application scenarios with varying temperature requirements.

[0010] Optionally, the electrode heating module is powered by a low voltage of 0.4-1kV.

[0011] By adopting the above technical solution, the electrode heating module is powered by a low voltage of 0.4-1kV, which eliminates the need for a high-voltage power supply system and expands the applicable scenarios of the low-voltage electrode boiler unit.

[0012] Optionally, the boiler unit also includes a boiler circulating pump disposed within the unit frame and spaced apart from the heating pipes, a heat exchanger disposed within the unit frame and away from the heating pipes, and a three-way regulating valve disposed within the unit frame and disposed between the boiler circulating pump and the heat exchanger. One end of the boiler circulating pump is connected to the main outlet pipe of the heating pipes through a pipeline, one end of the three-way regulating valve is connected to the other end of the boiler circulating pump, and the other two ends of the three-way regulating valve are respectively connected to the inlet and outlet of the heat exchanger.

[0013] By adopting the above technical solution, and by setting up a boiler circulating pump, a heat exchanger, and a three-way regulating valve, the boiler circulating pump can pump the heated hot water in the heating pipeline into the three-way regulating valve, and then the three-way regulating valve distributes it to the heat exchanger to realize the heat exchange between the hot water and the outside water. When it is necessary to adjust the heat distribution, the three-way regulating valve can adjust the flow rate of the hot water entering the heat exchanger according to the external network temperature to improve the heat exchange efficiency.

[0014] Optionally, the pipeline connecting the three-way regulating valve to the heat exchanger outlet is connected to the main water inlet pipe of the heating pipeline via a pipeline.

[0015] By adopting the above technical solution, by connecting the three-way regulating valve to the heat exchanger outlet and the heating pipeline inlet main pipe, the water that has been heated by the heat exchanger can flow back to the heating pipeline inlet main pipe through this pipeline, and then enter the electrode heating module for reheating, forming a hot water recycling path.

[0016] Optionally, a safety valve is installed at the top of the main outlet pipe of the heating pipeline.

[0017] By adopting the above technical solution and setting a safety valve, the pressure inside the heating pipeline can be regulated to maintain a stable pressure and improve the stability of the heating pipeline operation.

[0018] Optionally, the boiler unit may also include a control cabinet located within the unit frame away from the end of the heating pipes, the control cabinet being connected to multiple electrode heating modules.

[0019] By adopting the above technical solution and setting up a control cabinet that is connected to multiple electrode heating modules, the number of electrode heating modules that are put into operation can be controlled through the control cabinet, thereby realizing the regulation of the heating power of the boiler unit.

[0020] Optionally, the boiler unit may also include a power cabinet located between the control cabinet and the heating pipes within the unit frame.

[0021] By adopting the above technical solution and setting up a power cabinet, a stable power supply can be provided for the entire low-voltage electrode boiler unit, ensuring the normal operation of all electrical equipment in the unit and providing power support for the unit's heat energy conversion and supply process.

[0022] In summary, this application has the following technical effects: 1. By setting up a unit frame, heating pipes, electrode heating modules and manual valves, the electrode heating modules convert electrical energy into heat energy. The connection and disconnection between the electrode heating modules and the heating pipes can be adjusted by the manual valves. When one or more electrode heating modules fail, they can be cut off by the manual valves, while the other electrode heating modules can still keep running, allowing for inspection and maintenance without shutting down the system, thus improving heating efficiency. 2. By setting multiple electrode heating modules, each of which is individually connected to the heating pipeline, each electrode heating module can independently form a path with the heating pipeline. The heating power can be adjusted by controlling the number of electrode heating modules in operation, adapting to different application scenarios with different temperature requirements. 3. By installing a boiler circulating pump, heat exchanger, and three-way regulating valve, the boiler circulating pump can pump the heated hot water in the heating pipeline into the three-way regulating valve, and then the three-way regulating valve distributes it to the heat exchanger to realize the heat exchange between the hot water and the outside water. When it is necessary to adjust the heat distribution, the three-way regulating valve can adjust the flow rate of hot water entering the heat exchanger according to the external network temperature to improve the heat exchange efficiency.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a low-voltage electrode boiler unit, referring to... Figure 1The boiler unit includes a frame 1 for placing the boiler unit, multiple electrode heating modules 2 installed in the frame 1, a boiler circulation pump 3 installed in the frame 1, a heat exchanger 4 installed in the frame 1, a three-way regulating valve 5 installed in the frame 1 connecting the electrode heating modules 2 and the heat exchanger 4, a control cabinet 6 installed in the frame 1, and a power cabinet 7 installed in the frame 1. The frame 1 includes a horizontally arranged base 11 and a mounting frame 12 assembled from multiple crossbars on the upper surface of the base 11. The mounting frame 12 is a square column frame, and the length direction of the mounting frame 12 is parallel to the length direction of the base 11. The end face and side wall of the mounting frame 12 are flush with the end face and side wall of the base 11, respectively.

[0027] Reference Figure 1 and Figure 2 Multiple electrode heating modules 2 are installed at one end of the unit frame 1 along its length via heating pipes 21. The heating pipes 21 are square column-shaped frames assembled from multiple water pipes, perpendicular to the upper surface of the base 11 along their length. The heating pipes 21 and mounting brackets 12 are spaced apart. The electrode heating modules 2 are horizontally distributed in multiple layers, with each layer's modules parallel to each other along their length and spaced apart. The multiple electrode heating modules 2 are connected in series / parallel. Each electrode heating module 2 is individually connected to the heating pipes 21 for unified water replenishment or drainage. The heating power can be adjusted by controlling the number of electrode heating modules 2 in operation to adapt to different temperature requirements. The electrode heating modules 2 use a low voltage power supply of 0.4-1kV, eliminating the need for a high-voltage power supply system and thus having a wider range of applications.

[0028] Reference Figure 1 and Figure 2 A manual valve is installed between multiple electrode heating modules 2 and the heating pipe 21. The manual valve allows for the adjustment of the connection and disconnection between the electrode heating modules 2 and the heating pipe 21. If one or more electrode heating modules 2 malfunction, the connection can be cut off via the manual valve, while the other electrode heating modules 2 can continue to operate, allowing for uninterrupted inspection and maintenance, thus improving heating efficiency. A safety valve 22 is installed at the top of the main outlet pipe of the heating pipe 21. The safety valve 22 regulates the pressure within the heating pipe 21, improving its stability.

[0029] Combination Figures 1 to 3A boiler circulating pump 3 is installed on the upper surface of the base 11, spaced apart from the heating pipe 21. The boiler circulating pump 3 is located on the side wall near the base 11, and one end of the boiler circulating pump 3 is connected to the main outlet pipe of the heating pipe 21 via a pipe. A heat exchanger 4 is installed at the end of the upper surface of the base 11, on the side of the boiler circulating pump 3 away from the heating pipe 21. The heat exchanger 4 exchanges heat between the heated water in the heating pipe 21 and the outside water. A three-way regulating valve 5 is installed between the boiler circulating pump 3 and the heat exchanger 4. One end of the three-way regulating valve 5 is connected to the other end of the boiler circulating pump 3, and the other two ends of the three-way regulating valve 5 are connected to the inlet and outlet of the heat exchanger 4, respectively. The pipe connecting the three-way regulating valve 5 to the outlet of the heat exchanger 4 is connected to the main inlet pipe of the heating pipe 21 via a pipe. The three-way regulating valve 5 can regulate the flow rate of hot water entering the heat exchanger 4, thereby improving the heat exchange efficiency. The boiler circulation pump 3 pumps the heated hot water in the heating pipe 21 into the heat exchanger 4 through the three-way regulating valve 5. After heat exchange, the hot water flows back into the heating pipe 21 and is reheated by the electrode heating module 2, thus realizing the heating cycle.

[0030] Reference Figure 3 and Figure 4 The control cabinet 6 is located at the end of the mounting bracket 12 away from the heating pipe 21 and spaced apart from the heat exchanger 4. The control cabinet 6 is connected to multiple electrode heating modules 2 and is used to control the number of electrode heating modules 2 in operation. The power cabinet 7 is located between the control cabinet 6 and the heating pipe 21, and the power cabinet 7 provides power to the boiler unit.
