Description

Technical Field

[0001] The present application relates to the technical field of circulating heating, and in particular to a circulating heating device applied to thermal oil. Background Art

[0002] Thermal oil is primarily used to transfer heat. Common types include mineral oil, silicone oil, and polymer oil. Due to its high thermal conductivity and low viscosity, it can operate stably at high temperatures. Therefore, it is widely used in industrial heat exchange systems, heating equipment, and cooling systems. A circulating heating device heats the thermal oil and circulates it to these heat exchange devices.

[0003] Existing heat exchange systems, heating equipment, and other systems often require shutting down the circulating heating device to prevent internal heat transfer oil circulation and prevent suffocation. When the equipment is repaired and restarted, the heating tank in the circulating heating device must be overloaded to quickly reach the operating temperature of the heat transfer oil, posing a safety hazard. Furthermore, existing technologies control the heat transfer oil temperature solely through flow control, a limited control method that fails to achieve rapid temperature control. Utility Model Content

[0004] In view of the above problems, an embodiment of the present application provides a circulating heating device for thermal oil, which can perform internal circulation and store heat energy when the equipment is stopped. When the equipment is repaired, it can quickly heat up to a usable state and has multiple temperature control methods.

The circulating heat supply device for thermal oil includes a support frame, on which a heating box, a first buffer cylinder, a second buffer cylinder and a filter assembly are supported, a heating assembly is provided in the heating box, the heating box is connected to a main water supply pipeline through a pump body and a first water outlet pipe, the middle of the first water outlet pipe is connected to the first buffer cylinder and the second buffer cylinder through a first diversion pipe and a second diversion pipe respectively, the first buffer cylinder and the second buffer cylinder are connected to the main water supply pipeline through a second water outlet pipe and a third water outlet pipe respectively, the first buffer cylinder and the second buffer cylinder are connected to the heating box through a return pipe respectively, a temperature detection assembly, a pressure detection assembly and a pressure regulating valve are provided on the first buffer cylinder, the first buffer cylinder is connected to the filter assembly through a pipeline and a water pump, and the outlet end of the filter assembly is connected to the second buffer cylinder through a pipeline.

[0006] In some embodiments, the filter assembly includes a first filter cartridge and a second filter cartridge that are detachably connected to the support frame through a snap-fit ​​portion, and a filter tube is connected to the bottom of the first buffer cartridge. The filter tube is connected to the first filter cartridge and the second filter cartridge respectively through a first filter branch pipe and a second filter branch pipe, and the top ends of the first filter cartridge and the second filter cartridge are connected to the second buffer cartridge respectively through a first return water pipe and a second return water pipe.

Subsequently, when the temperature requirement of the heat exchange system rises, the heating box, the first and second buffer cylinders can all synchronously transport the heat transfer oil to the main water supply pipe through the pipes to achieve the purpose of rapidly raising the temperature.

[0020] Specifically, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of a circulating heating device for thermal oil provided in an embodiment of the present application. Figure 2This is a schematic structural diagram of a circulating heating device for thermal oil provided in an embodiment of the present application from another perspective. Figure 3 A schematic diagram of the local structure of the filter assembly provided in an embodiment of the present application. The circulating heat supply device 100 applied to thermal oil includes a support frame 110. The support frame 110 can be welded from a steel structure. Its specific structure can be set according to actual conditions and will not be limited here. A heating box 120, a first buffer cylinder 130, a second buffer cylinder 140 and a filter assembly 150 are supported on the support frame 110. The heating box 120 is used to heat the thermal oil. The first buffer cylinder 130 and the second buffer cylinder 140 can both receive the thermal oil from the heating box 120 and temporarily store it. A heating assembly is provided in the heating box 120. The heating assembly is a prior art and is used to heat the thermal oil in the heating box 120 to increase its temperature. The heating box 120 is connected to a main water supply pipe 124 through a pump body and a first water outlet pipe 121. The end of the main water supply pipe 124 is connected to a corresponding heat exchange system, heating equipment, etc. The water outlets of the corresponding heat exchange systems, heating equipment, etc., are connected through corresponding pipes and flow back into the heating tank 120. The middle portion of the first water outlet pipe 121 is connected to the first and second buffer cylinders 130, 140 via the first and second diverter pipes 122, 123, respectively. It should be noted that, as is well known to those skilled in the art, corresponding valves should be installed on these pipes. Since the design of these valves is common knowledge, they will not be described in detail here. Thermal oil in the heating tank 120 can flow through the first and second diverter pipes 122, 123, respectively, into the first and second buffer cylinders 130, 140. The first and second buffer cylinders 130, 140 are connected to the main water supply pipe 124 via the second and third water outlet pipes 131, 141, respectively. The high-temperature thermal oil in the first and second buffer cylinders 130, 140 can be fed through the second and third water outlet pipes 131, 141, and then fed through the main water supply pipe 124 to the corresponding heat exchange systems, heating equipment, etc. for use. The first and second buffer cylinders are connected to the heating box 120 via a return pipe 160. When the return pipe 160 is connected, the thermal oil in the heating box 120 circulates between the first and second buffer cylinders 130, 140, achieving continuous heating. The first buffer cylinder is equipped with a temperature detection assembly 170, a pressure detection assembly, and a pressure-stabilizing valve 180. The temperature detection assembly 170 is used to measure the internal temperature, and the pressure detection assembly is used to detect the internal air pressure of the first buffer cylinder. The pressure-stabilizing valve 180 regulates the internal temperature of the first buffer cylinder by controlling its opening and closing. The first buffer cylinder 130 is connected to the filter assembly 150 via a pipe and a water pump. The outlet of the filter assembly 150 is connected to the second buffer cylinder 140 via a pipe. After the thermal oil in the first buffer cylinder 130 is filtered by the filter assembly 150, it can enter the second buffer cylinder 140 for standby use.

[0021] From the above, it can be seen that in the embodiment of the present application, when the heat exchange system, heating equipment, etc. that are matched with this equipment are working normally, the heat transfer oil in the heating box 120 is normally transported to the heat exchange system, heating equipment, etc. through the main water supply pipe 124, and part of the heat transfer oil is transported to the first buffer cylinder through the first diversion pipe 122. Then, the heat transfer oil in the first buffer cylinder can be filtered through the filter component 150 and then enter the second buffer cylinder for standby. The heat transfer oil in the second buffer cylinder can then be merged into the main water supply pipe 124 through the third water outlet pipe 141 for use, and will not cause blockage to the pipeline of the entire heat exchange system during the filtration process. When the equipment is shut down or the temperature required by the corresponding heat exchange system is low, the main water supply pipe 124 is cut off or the flow is reduced by controlling the opening and closing of the corresponding valve body. At the same time, the remaining heat transfer oil in the heating box 120 circulates between the heating box 120 and the first buffer cylinder 130 and the second buffer cylinder 140 through the first diversion pipe 122 and the second diversion pipe 123 and the return pipe 160 and continues to heat up, thereby continuously heating the heat transfer oil. Subsequently, when the temperature demand of the heat exchange system rises, the heating box 120, the first buffer cylinder and the second buffer cylinder can all synchronously transport the heat transfer oil to the main water supply pipe 124 through the pipeline to achieve the purpose of quickly increasing the temperature.

[0022] In some embodiments, the filter assembly 150 includes a first filter cartridge 152 and a second filter cartridge 153 detachably connected to the support frame 110 via a snap-fit ​​portion 151. A filter tube 154 is connected to the bottom of the first buffer cartridge 130. The filter tube 154 is connected to the first filter cartridge 152 and the second filter cartridge 153 via a first filter branch pipe 155 and a second filter branch pipe 156, respectively. The top ends of the first filter cartridge 152 and the second filter cartridge 153 are connected to the second buffer cartridge 140 via a first return pipe 157 and a second return pipe 158, respectively. In the embodiment of the present application, a specific arrangement of the filter assembly 150 is shown. Since there are two filter tubes in the embodiment of the present application, the two filter cartridges can be used alternately by controlling the opening and closing of the corresponding valve bodies. When one filter cartridge needs to be cleaned, the other filter cartridge can continue to be used without affecting it.

[0023] In some embodiments, the snap-fit ​​portion 151 includes a plurality of support platforms 151a connected to the support frame 110. U-shaped elastic members 151b are disposed on the support platforms 151a, and the first filter cartridge 152 and the second filter cartridge 153 are respectively snapped into the U-shaped elastic members 151b. In the embodiment of the present application, this arrangement allows the first filter cartridge 152 and the second filter cartridge 153 to be easily and quickly removed from or secured to the mounting frame during cleaning.

[0024] In some embodiments, flange adapters 159 are provided at the head and tail ends of the first filter cartridge 152 and the second filter cartridge 153. In the present embodiment, the flange adapters 159 connect the first filter cartridge 152 and the second filter cartridge 153 to the corresponding pipes, which ensures the stability of the connection and facilitates disassembly.

[0025] In some embodiments, a PLC control box is included, and the PLC control box is electrically connected to the temperature detection component 170 and the pressure regulating valve 180. In the embodiment of the present application, by setting up the PLC control box, the temperature detection component 170 and the pressure detection component can transmit corresponding data in the form of electrical signals to the PLC control box, and the PLC control box further controls the corresponding valve body for automatic adjustment.

[0026] In some embodiments, a plurality of reinforcing plates are connected to the bottom of the support frame 110. In the embodiment of the present application, the reinforcing plates are provided to enhance the stability of the device.
