Description

Technical Field

[0001] This utility model relates to the field of electric heating furnace technology, and in particular to an energy-saving electric heating furnace. Background Technology

[0002] There are many types of heating furnaces, including electric heating furnaces. Traditional electric heating furnaces usually use resistance heating rods that are directly immersed in water for heating.

[0003] This heating method has several obvious drawbacks: First, scale easily forms on the surface of the heating element, which not only reduces thermal efficiency and increases energy consumption but also shortens the equipment's lifespan. Second, the single heat source results in limited heating efficiency and high energy consumption. Third, the water system lacks effective online filtration and self-cleaning functions; long-term operation can lead to impurities accumulating and clogging pipes or damaging the equipment, requiring maintenance and cleaning with shutdown and disassembly, which is very inconvenient. Furthermore, traditional control methods are not intelligent enough to precisely maintain stable water temperature, affecting heating comfort. Therefore, the market urgently needs an electric heating boiler that is highly efficient, energy-saving, environmentally friendly, self-cleaning, and precisely controlled. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing an energy-saving electric heating furnace.

[0005] The technical solution of this utility model is as follows: An energy-saving electric heating furnace includes a furnace body, a heating water tank is installed inside the furnace body, an electric heater is installed inside the heating water tank, the output end of the heating water tank is connected to an outlet pipe, and the input end of the heating water tank is connected to an inlet pipe. A hollow plate is installed inside the furnace body. A cylindrical cavity is set inside the hollow plate. The end of the water inlet pipe away from the heating water tank is connected to the hollow plate and communicates with the cylindrical cavity. A return pipe, a drain pipe, an air blowing pipe and a water filling pipe are set on the hollow plate and communicate with the cylindrical cavity. The water inlet pipe, the air blowing pipe and the water filling pipe are arranged in a ring array around the axis of the cylindrical cavity. The water inlet pipe and the return pipe are radially symmetrical about the cylindrical cavity, and the drain pipe and the air blowing pipe are radially symmetrical about the cylindrical cavity. A disc is rotatably mounted inside a cylindrical cavity. Several through holes are arranged in a circular array around the disc's axis, and a filter screen coaxial with the disc is installed inside each through hole. And a drive component, which is set on the hollow plate and drives the connected disk.

[0006] Preferably, a temperature control mechanism is provided on the heating water tank. The temperature control mechanism includes a temperature sensor and a control component. The temperature sensor is located inside the heating water tank and is electrically connected to the control component.

[0007] Preferably, the control components include a control panel, with an access door provided on the furnace body, and the control panel is mounted on the access door.

[0008] Preferably, the exterior of the heating water tank is covered with a carbon fiber heating layer in a U-shaped enclosed structure, and the carbon fiber heating layer is tightly bonded to the body of the heating water tank through an insulating and thermally conductive material.

[0009] Preferably, the carbon fiber heating layer is composed of multiple parallel carbon fiber heating wires, and the furnace body is also filled with a layer of heat-insulating material covering the outside of the carbon fiber heating layer.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: By employing a carbon fiber heating layer encased in a U-shaped, enclosed structure around the heating water tank and tightly bonded with insulating and thermally conductive materials, large-area, high-efficiency heating is achieved with a high heat conversion rate. Combined with the internal insulation layer of the furnace body, heat loss is greatly reduced, resulting in significant energy savings. The innovative filtration mechanism design, with through-holes containing filter screens on a rotating disc, enables online switching of filtration functions. When one filter screen becomes clogged, the drive component can switch to the cleaning path, ensuring continuous system operation without interruption. Simultaneously, air blowing and drain pipes can be used to clean clogged filters by reverse air blowing and remove impurities, achieving self-cleaning without shutting down the system and greatly reducing maintenance difficulty and workload. Before being reused for filtration, the cleaned through-holes are rotated to connect with the water supply pipe for water filling. This design ensures that the through-holes are full of water when reconnected to the main water circuit, effectively preventing air from entering the water circulation system, maintaining stable system water pressure, and ensuring the reliability and quiet operation of the heating system.

[0016] Example 1, as Figures 1-5 As shown, this utility model proposes an energy-saving electric heating furnace, comprising a furnace body 1, a hollow plate 9, a disc 15, and a drive assembly. A heating water tank 4 is installed inside the furnace body 1. The heating water tank 4 is externally covered with a carbon fiber heating layer using a U-shaped enclosed structure. The carbon fiber heating layer is tightly bonded to the body of the heating water tank 4 through an insulating and thermally conductive material. The carbon fiber heating layer consists of multiple parallel-arranged carbon fiber heating wires. The furnace body 1 is also filled with an insulation material layer covering the outside of the carbon fiber heating layer. An electric heater 5 is installed inside the heating water tank 4. The output end of the heating water tank 4 is connected to an outlet pipe 7, and the input end of the heating water tank 4 is connected to an inlet pipe 8. Several partitions 6 are staggered inside the heating water tank 4 to form a serpentine channel within the heating water tank 4. The outlet pipe 7 and the inlet pipe 8 are respectively connected to the output and input ends of the serpentine channel. A temperature control mechanism is installed on the heating water tank 4, including a temperature sensor and a control assembly. The temperature sensor is installed inside the heating water tank 4 and electrically connected to the control assembly. The control components include a control panel 3, with an access door 2 mounted on the furnace body 1. The control panel 3 is mounted on the access door 2. The control panel 3 uses a combination of HMI (Human Machine Interface) and PLC (Programmable Logic Controller). The HMI provides users with an intuitive and user-friendly interface, allowing them to easily issue various commands via touchscreen.

[0017] A hollow plate 9 is disposed inside the furnace body 1. A cylindrical cavity is formed inside the hollow plate 9. The end of the water inlet pipe 8 away from the heating water tank 4 is connected to the hollow plate 9 and communicates with the cylindrical cavity. A return pipe 10, a drain pipe 11, an air blowing pipe 12, and a water filling pipe 13, all communicating with the cylindrical cavity, are disposed on the hollow plate 9. The water inlet pipe 8, the air blowing pipe 12, and the water filling pipe 13 are arranged in a ring array around the axis of the cylindrical cavity. The water inlet pipe 8 and the return pipe 10 are radially symmetrical about the cylindrical cavity, and the drain pipe 11 and the air blowing pipe 12 are radially symmetrical about the cylindrical cavity. A disc 15 is rotatably disposed inside the cylindrical cavity. Several through holes 151 are arranged in a ring array around the axis of the disc 15. A filter screen 16 coaxial with the disc is disposed in each of the through holes 151. The drive components include, but are not limited to, a servo motor 17. The body of the servo motor 17 is mounted on the hollow plate 9. The output end of the servo motor 17 is connected to the central axis of the disk 15 via a coupling. A control button for driving the servo motor 17 is provided on the hollow plate 9. Each time this control button is pressed, the servo motor 17 drives the disk 15 to rotate 120 degrees.

[0018] In this embodiment, the electric heating furnace heats water through a heating water tank 4 and uses a carbon fiber heating layer for auxiliary heating, achieving a highly efficient and energy-saving heating effect. The carbon fiber heating layer consists of multiple parallel carbon fiber heating wires, which are tightly bonded to the body of the heating water tank 4 through insulating and thermally conductive material, thereby efficiently transferring heat to the heating water tank 4. The furnace body 1 is filled with an insulation material layer covering the outside of the carbon fiber heating layer to reduce heat loss and improve energy efficiency. Several baffles 6 are staggered inside the heating water tank 4 to form a serpentine channel, extending the flow time of water in the heating water tank 4 and ensuring sufficient heating. The inlet pipe 8 introduces water into the inlet end of the serpentine channel of the heating water tank 4. The water is heated by the electric heater 5 and the carbon fiber heating layer as it flows through the serpentine channel, and finally outputs the heated water from the outlet pipe 7 to supply the heating system.

[0019] The temperature control mechanism is responsible for regulating the water temperature. A temperature sensor is installed inside the heating water tank 4 to monitor the water temperature in real time and transmit the signal to the control component. The control component includes a control panel 3, which uses a combination of HMI and PLC. Users can set temperature parameters through the touch interface of the control panel 3. The PLC automatically controls the operation of the electric heater 5 and the carbon fiber heating layer based on the feedback from the temperature sensor to maintain the set temperature.

[0020] A control button is installed on the hollow plate 9. Each time the user presses the control button, the servo motor 17 drives the disc 15 to rotate 120 degrees. In this way, when the filter screen 16 of a certain through hole 151 is blocked by impurities, rotating the disc 15 will align another clean through hole 151 with the water flow channel, ensuring that the filtration function remains effective. At the same time, the blocked filter screen 16 rotates between the drain pipe 11 and the air blowing pipe 12. Using a hot air gun, air is blown into the air blowing pipe 12, and the filter screen 16 in the through hole 151 is cleared by the airflow. Impurities and water are discharged through the drain pipe 11. The next time the through hole 151 is sequentially switched to be aligned with the water inlet pipe 8, the through hole 151 that has been cleaned of impurities rotates to be aligned with the water filling pipe 13. At this time, water can be filled into the through hole 151 through the water filling pipe 13, thus ensuring that the water pressure environment in the original water circulation loop is not disrupted when the through hole 151 returns to the state of being aligned with the water inlet pipe 8.

[0021] Example 2, as Figure 3 and Figure 4 As shown, the present invention proposes an energy-saving electric heating furnace. Compared with the first embodiment, the sewage pipe 11 is equipped with a valve 111 for controlling the switch of its internal channel, and the air blowing pipe 12 is equipped with a one-way valve 121. The one-way valve 121 is only opened when air is blown into the corresponding side through hole 151 along the air blowing pipe 12.

[0022] In this embodiment, since the entire water circulation pipeline is under high pressure, the sealing performance of the entire water circulation loop device can be improved by adding valve 111 and check valve 121 to prevent water from overflowing in the circulation loop.

[0023] Example 3, as Figure 2 and Figure 3 As shown, the present invention proposes an energy-saving electric heating furnace. Compared with the first embodiment, the furnace body 1 is equipped with a water tank 14. The water tank 14 is located above the hollow plate 9. The input end of the water supply pipe 13 is inserted into the water tank 14 and located below the liquid surface. The water supply pipe 13 is also equipped with a one-way valve, which only allows the water in the water tank 14 to flow down into the through hole 151.

[0024] In this embodiment, since the water and impurities inside the through hole 151 connected to the sewage pipe 11 are discharged, the total amount of water in the entire circulation loop will be reduced. At this time, when the through hole 151 is rotated to be aligned with the water supply pipe 13, the water in the water tank 14 automatically enters the through hole 151 along the water supply pipe 13 and refills the inside with water free of impurities, thereby automatically maintaining a constant water pressure in the entire circulation loop.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
