Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal oil furnace technology, and more specifically, to an energy-saving thermal oil furnace. Background Technology
[0002] A thermal oil heater is a new type of thermal energy equipment that uses coal, oil, or gas as fuel and thermal oil as the circulating medium for heating. It directly inserts an electric heater into an organic carrier for direct heating, and then uses a high-temperature oil pump to circulate the heated thermal oil in the liquid phase to deliver it to the heat-using equipment. The oil then returns to the electric heating oil heater from the outlet of the heat-using equipment for further heating, forming a complete circulating heating system.
[0003] After searching, it was found that application number CN202421257483.9, entitled "An Energy-Saving Thermal Oil Furnace," was filed with Chinese Patent Publication No. CN208567129U. This application discloses an energy-saving thermal oil furnace that addresses the problem that heating the thermal oil furnace affects the motor temperature, leading to overheating and potential malfunctions or even damage. The proposed solution utilizes a combination of the furnace body, motor, fan blades, and insulation sleeve to effectively cool the motor, preventing overheating and damage, thus extending the motor's lifespan and increasing its practicality. However, in actual heat dissipation, the high ambient temperature makes efficient airflow through the fan blades difficult, requiring further improvement. Additionally, the furnace body is exposed to the air, leading to heat leakage and loss, increasing energy consumption and detracting from energy efficiency and environmental friendliness. Further improvements are needed.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides an energy-saving thermal oil furnace, which has the following beneficial effects:
[0019] (1) This utility model adopts a spray box, which is installed on the outside of the drive motor and reducer. The industrial chiller pumps out low-temperature insulating coolant through the spray pipe and sprays it onto the surface of the drive motor and reducer through the nozzle. The low-temperature insulating coolant cools the drive motor and reducer, avoiding damage to the drive motor and reducer. At the same time, the insulating coolant has good insulation and corrosion resistance, which has no effect on the drive motor and reducer. It can also penetrate into the drive motor and reducer to complete deep cooling, and the cooling effect is more efficient.
[0020] (2) This utility model adopts an insulation box, which is installed on the outside of the main body of the thermal oil furnace. The hot oil flows out through the oil outlet pipe and is pumped back after being circulated by the pump body. The heat radiation generated by the main body of the thermal oil furnace is confined in the insulation box, which reduces heat loss and is more energy-efficient and environmentally friendly. It avoids the problem of traditional thermal oil furnaces being exposed to the air and having serious surface heat loss, resulting in serious energy consumption. Attached Figure Description

A pump body 8 is fixedly installed on the other side of the spray box 16 on the top surface of the base plate 1. The input shaft of the pump body 8 is connected to the drive motor 9 via the reducer 10. This is a common drive structure in the art. A pump pipe 7 is connected through the input end of the pump body 8, and the output end of the pump body 8 is connected through the oil return pipe 6 to the oil inlet end of the thermal oil furnace body 4. The output end of the water chiller 11 is connected to a spray pipe 14, which extends into the spray box 16. A nozzle 15 is connected to the surface of the spray pipe 14 above the drive motor 9 and the reducer 10. The nozzle 15 sprays insulating coolant vertically downwards. The spray box 16 is mounted on the outside of the drive motor 9 and the reducer 10. The industrial chiller 11 pumps out low-temperature insulating coolant through the spray pipe 14, which is then sprayed onto the surface of the drive motor 9 and the reducer 10 through the nozzle 15. The low-temperature insulating coolant cools the drive motor 9 and the reducer 10, preventing damage to them. At the same time, the insulating coolant has good insulation and corrosion resistance, so it has no effect on the drive motor 9 and the reducer 10. It can also penetrate into the drive motor 9 and the reducer 10 to achieve deep cooling, resulting in higher cooling efficiency.
[0031] In one embodiment, a water pump 12 is fixedly installed on the top surface of the base plate 1 between the spray box 16 and the industrial chiller 11. The input end of the water pump 12 is connected to the bottom of the spray box 16 through the return pipe 13, and the output end of the water pump 12 is connected to the input end of the industrial chiller 11 to facilitate the circulation and cooling of the insulating coolant.
[0032] In one embodiment, the oil outlet end of the thermal oil furnace body 4 is connected to an oil outlet pipe 5, and the oil outlet pipe 5 extends out of the insulation box 3, which facilitates the connection of the oil outlet pipe 5 to the equipment.
[0033] In one embodiment, an insulation layer is bonded to the outer surface of the insulation box 3, and the thickness of the insulation layer is not less than 5cm. The insulation box 3 is covered outside the main body 4 of the thermal oil furnace. The hot oil flows out through the oil outlet pipe 5 and is pumped back after being circulated by the pump body 8. The heat radiation generated by the main body 4 of the thermal oil furnace is confined inside the insulation box 3, which reduces heat loss and is more energy-efficient and environmentally friendly. This avoids the problem of traditional thermal oil furnaces being exposed to the air and having serious surface heat loss leading to serious energy consumption.
[0034] In one embodiment, the back of the insulated box 3 is hinged with an inspection door 17 for easy opening and maintenance.
[0035] In one embodiment, the spray box 16 has a door hinged to its front facade, and the door is a sealed door, which is convenient to open for maintenance.
[0036] In one embodiment, multiple sets of nozzles 15 are arranged at equal intervals to increase the coverage of spraying for cooling and improve work efficiency.
[0037] In one embodiment, the input shaft of the pump body 8 passes through the spray box 16 and is rotatably connected to the spray box 16 via a bearing, which is a common connection method.
[0038] Working principle:
[0039] The spray box 16 is mounted on the outside of the drive motor 9 and the reducer 10. The industrial chiller 11 pumps out low-temperature insulating coolant through the spray pipe 14, which is then sprayed onto the surface of the drive motor 9 and the reducer 10 through the nozzle 15. The low-temperature insulating coolant cools the drive motor 9 and the reducer 10, preventing damage to them. At the same time, the insulating coolant has good insulation and corrosion resistance, so it has no effect on the drive motor 9 and the reducer 10. It can also penetrate into the drive motor 9 and the reducer 10 to achieve deep cooling, resulting in higher cooling efficiency. Meanwhile, the insulation box 3 is installed on the outside of the thermal oil furnace body 4. The hot oil flows out through the oil outlet pipe 5, is circulated by the pump body 8, and is pumped back. The heat radiation generated by the thermal oil furnace body 4 is confined inside the insulation box 3, reducing heat loss and making it more energy-efficient and environmentally friendly. This avoids the problem of traditional thermal oil furnaces being exposed to the air, resulting in serious surface heat loss and high energy consumption.
