[0004] The components such as the oil tank, circulating oil pump, and heater in the above patent work together to achieve the effects of low cost, simple structure, convenient use, and scientific practicality. However, they cannot achieve better uniform heating of the oil tank. Therefore, we propose an automatic heating device for the oil tank of the hot air furnace hydraulic station. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology in that it is not possible to achieve better uniform heating inside the oil tank.

A heating tube is fixedly connected to the inner side of the heater, and a limit rod is fixedly connected to the inner side of the oil tank. The circumference of the threaded sleeve and the circumference of the limit rod are slidably connected. The function of this uniform heating device is to drive the threaded rod and threaded sleeve with the motor, causing the heater to move uniformly within the oil tank, thus efficiently and evenly heating the liquid in the tank. Simultaneously, the design of the limit rod ensures that the heater does not exceed a predetermined position within the oil tank, guaranteeing a safe and stable heating process.
[0008] Preferably, multiple heating elements are provided, and casters are provided at the bottom of the base. By distributing multiple heating elements in different areas of the oil tank, heat can be evenly distributed in the oil, avoiding uneven heating that could cause localized overheating or insufficient temperature.

The design of this anti-solidification device mainly achieves continuous stirring and cleaning of the liquid in the oil tank through a series of mechanical structures, preventing the oil from solidifying, settling, or accumulating impurities, thus maintaining the fluidity of the oil and the efficient operation of the heating system.
[0011] Preferably, the gear meshes with the rack, and there is a gap between the bottom of the moving screen plate and the top of the glass cover. The specific function needs further analysis in conjunction with the equipment's function and design goals; these gaps and mechanical designs are intended to optimize equipment performance, increase durability, and ensure efficient operation.
[0012] Preferably, the inner side of the oil tank is located on the displacement trajectory of the moving screen plate, and there is a gap between the top of the moving screen plate and the bottom of the tank cover. This gap design ensures smooth movement of the moving screen plate, avoids material accumulation, reduces friction, supports liquid flow, and prevents pressure buildup. It contributes to smooth equipment operation, extends service life, and optimizes the oil filtration and cleaning process.
[0013] Preferably, there is a gap between the side of the movable screen plate and the inner side of the oil tank, and multiple casters are provided. The gap design and the multiple casters work together to ensure the smooth and free movement of the movable screen plate, reduce friction and material accumulation, enhance the stability and flexibility of the equipment, and improve the ease of operation and durability of the equipment.
[0014] Compared with existing technologies, the beneficial effects of this utility model include: starting the motor, which drives the threaded rod to rotate; the rotation of the threaded rod causes the threaded sleeve to move horizontally under the restriction of the limiting rod; the horizontal movement of the threaded sleeve causes the force-bearing rod to move horizontally; the horizontal movement of the force-bearing rod causes the heater to move horizontally; the horizontal movement of the heater causes the heating tube to move horizontally; and the horizontal movement of the heater causes the glass cover to move horizontally. This achieves efficient and uniform heating of the liquid in the oil tank, reduces operating costs, improves the stability and reliability of the hot blast stove hydraulic station, and ensures the safe and stable operation of the hot blast stove equipment, thereby guaranteeing the normal production of the blast furnace.
[0015] Compared with existing technologies, the beneficial effects of this utility model include: starting the motor, the motor drives the threaded rod to rotate, the rotation of the threaded rod drives the gear to rotate, the rotation of the gear drives the meshing rack to move horizontally, the horizontal movement of the rack drives the moving rod to move horizontally, and the horizontal movement of the moving rod drives the moving screen plate to move horizontally inside the oil tank. The horizontal movement of the moving screen plate ensures full contact with the oil inside the oil tank, squeezing the oil and causing it to move back and forth. This achieves continuous stirring and cleaning of the oil in the oil tank, preventing the oil from solidifying, settling, or accumulating impurities, maintaining the fluidity of the oil and the efficient operation of the heating system.

A heating tube 86 is fixedly connected to the inner side of the heater 85. A limit rod 87 is fixedly connected to the inner side of the oil tank 6. The circumferential surface of the threaded sleeve 83 is slidably connected to the circumferential surface of the limit rod 87. The function of this uniform heating device 8 is to drive the threaded rod 82 and the threaded sleeve 83 through the motor 81, so that the heater 85 moves uniformly within the oil tank 6, thereby efficiently and uniformly heating the liquid in the oil tank 6. At the same time, the design of the limit rod 87 ensures that the heater 85 will not exceed the predetermined position within the oil tank 6, guaranteeing a safe and stable heating process.
[0026] Multiple heating tubes 86 are provided, and casters 2 are provided at the bottom of the base 1. By distributing multiple heating tubes 86 in different areas of the oil tank 6, heat can be evenly distributed in the oil, avoiding uneven heating that could cause local overheating or insufficient temperature.

The horizontal movement of the rack 92 drives the moving rod 93 to move horizontally, which in turn drives the moving screen plate 94 to move horizontally inside the oil tank 6. The moving screen plate 94 makes full contact with the oil inside the oil tank 6, squeezing the oil and causing it to move back and forth. This achieves continuous stirring and cleaning of the oil in the oil tank 6, preventing the oil from solidifying, settling, or accumulating impurities.
