[0031] Further, the outer wall of the semi-sealed cover 11 is provided with a temperature display screen 12 for displaying the internal temperature, so that the operator can intuitively and real-timely monitor the temperature inside the heating furnace body 10, thereby ensuring the accuracy and safety of the heating process.

[0032] Among them, the heating plate 16 is installed on the top surface of the heating furnace body 10, and a plurality of uniformly equidistantly arranged through holes 17 are formed on the heating plate 16, so that the heat can be more uniformly transmitted to the heat conducting oil coil 13, thereby improving the heating efficiency and the heating uniformity of the heat conducting oil.

[0033] It is worth noting that the explosion-proof shell 15 is an explosion-proof ductile cast iron shell, and the thickness is 1-2 cm, so that the heating furnace body 10 can still maintain structural stability in high pressure and high temperature environment, effectively preventing explosion accidents caused by equipment failure or improper operation, and ensuring production safety.

[0034] It is worth noting that the number of layers of heat conducting oil coil 13 is 2-6 layers, which can adjust the heating capacity and efficiency of the heating furnace body 10 according to actual demand, flexibly cope with different heating demands, and improve the applicability and economy of the equipment.

[0035] Specifically, the bottom of each group of columns 20 is provided with a mobile wheel 21, and a fixed brake 22 for preventing the vehicle from sliding is installed on each group of mobile wheels 21, so that the semi-sealed safety explosion-proof heat conducting oil heating furnace can be conveniently moved and fixed, facilitating the layout adjustment and position transformation of the equipment, and improving the flexibility and working efficiency of the production line.

[0037] The working principle of the semi-sealed safety explosion-proof heat conducting oil heating furnace is as follows:

[0038] Firstly, the operator injects heat conducting oil into the heat conducting oil coil 13 through an external oil pump, connects the oil inlet pipe 40 and the oil return pipe 50 to external heat using equipment, and synchronously operates the electric heating net 14 on the inner side wall and the bottom of the heating furnace body 10 and the electric heating plate 16 during heating to provide additional heat source for the heat conducting oil, ensuring heating efficiency and uniformity. At the same time, the explosion-proof shell 15 effectively isolates the heat and pressure between the external environment and the inside of the heating furnace body 10, ensuring the safety of the equipment.

[0039] As the heat conducting oil continuously circulates in the heat conducting oil coil 13, the heat is gradually transferred to the entire inside of the heating furnace body 10. When the heat conducting oil reaches the set temperature, it enters the oil return pipe 50 through the oil outlet end of the bottommost heat conducting oil coil 13, completing a heating cycle.

[0040] During heating, the operator can monitor the temperature inside the heating furnace body 10 in real time through the temperature display screen 12 and make adjustments as needed. At the same time, the explosion-proof exhaust pipe 30 continuously discharges harmful gases and vapors generated during heating, maintaining the cleanliness and hygiene of the equipment.

[0041] The above shows and describes the basic principle, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and do not limit the present application.
