Technical Field

[0001] The utility model relates to the technical field of electric heating, in particular to an electric heating thermal oil furnace. Background Art

[0002] The electric thermal oil furnace is a new type of safe, efficient and energy-saving special industrial furnace with low pressure (normal pressure or lower pressure) and the ability to provide high-temperature heat. It uses thermal oil as a heat carrier and circulates the heat carrier through a hot oil pump to transfer heat to the heat-using equipment. In the production process of some chemical products, an electric heating thermal oil furnace is required for heating production. However, after production, since high-temperature chemical products are not easy to store, the chemical products need to be cooled to a certain temperature in the oil furnace before they can be discharged. However, since the oil furnace has good thermal insulation properties, the heat in the oil cannot be quickly dissipated, resulting in low efficiency in the production of chemical products. Therefore, it is necessary to design a new electric heating thermal oil furnace to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] Reference Figure 1-Figure 4As shown, the electrically heated thermal oil furnace comprises a furnace body 1, in which a return cavity 2 is arranged, two mounting plates 11 are fixedly connected to the left side of the furnace body 1, adjacent sides of the two mounting plates 11 are rotatably connected with transverse tubes, adjacent sides of the two transverse tubes are commonly connected with a serpentine tube 3, the serpentine tube 3 is a copper tube, and swivel joints 15 are arranged on the opposite sides of the two mounting plates 11, the two transverse tubes are connected with the corresponding swivel joints 15, the front side of the swivel joint 15 located on the front side is connected with the return cavity 2 through a bend pipe 14, a liquid storage tank 6 is arranged below the furnace body 1, heating oil is stored in the liquid storage tank 6, an electric heating plate is arranged in the liquid storage tank 6, the staff can control the operation of the electric heating plate through a switch, so as to heat the heating oil, the liquid storage tank 6 is connected with the rear side of the swivel joint 15 located on the rear side through a reflux pipe 4, a rubber layer is embedded in the left side of the furnace body 1, the rubber layer is made of high temperature resistant rubber, and the rubber layer has a certain elasticity, so as to reduce the noise generated by the serpentine tube 3 contacting and colliding with the furnace body 1 when it moves back.

[0018] A rotating gear 12 is provided on the front transverse tube, a driving motor 10 is installed on the front mounting plate 11, the output shaft end of the driving motor 10 passes through the mounting plate 11 and is fixedly connected with a half gear 13, and the rear transverse tube is elastically connected to the mounting plate 11 through a torsion spring.

[0019] A pump body is installed at the lower end of the furnace body 1. The liquid inlet end of the pump body is connected to the bottom space of the liquid storage tank 6 through the extraction pipe 7, the liquid outlet end of the pump body is connected to the bottom space of the return cavity 2, and the top space of the return cavity 2 is connected to the liquid storage tank 6 through the liquid outlet pipe 9. The liquid outlet pipe 9 and the horizontal pipe on the rear side are both provided with solenoid valves, which are all normally closed solenoid valves. The staff controls the on and off of the two solenoid valves through switches.

[0020] When heating the furnace body 1, the electric heating plate in the liquid storage tank 6 is controlled to operate, the heating oil is heated, and the pump body is started. At this time, the solenoid valve on the cross pipe is powered on, and the solenoid valve on the liquid outlet pipe 9 is powered on, so that the liquid outlet pipe 9 is in a conductive state. At this time, the operation of the pump body will form a circulation flow of the liquid storage tank 6 → pump body → return cavity 2 → liquid storage tank 6, thereby heating the furnace body 1 and producing chemical products; when the chemical products are produced and need to be cooled, the solenoid valve on the cross pipe can be controlled to be powered on, the solenoid valve on the liquid outlet pipe 9 is powered off, and the electric heating plate is powered off at the same time. At this time, the operation of the pump body forms a circulation flow of the liquid storage tank 6 → pump body → return cavity 2 → serpentine Tube 3→liquid storage tank 6 circulation, since the serpentine tube 3 is located on the outside of the furnace body 1, it will exchange gas with the outside, so that the heating oil flowing in the serpentine tube 3 is quickly cooled down; during the cooling process, the drive motor 10 is started to rotate the half gear 13. When the half gear 13 is engaged with the rotating gear 12, the rotating gear 12 drives the serpentine tube 3 to rotate upward. When the half gear 13 is not engaged with the rotating gear 12, the serpentine tube 3 is reset under the action of the torsion spring, so that the serpentine tube 3 is in a swinging state, so that there is gas flow around the serpentine tube 3, which further accelerates the efficiency of heat exchange between the heating oil and the external gas.
