[0024] In this embodiment, firstly, the connecting pipe 103 is fixed to one side of the oil storage tank body 101 and ensured to be in communication with the inside of the tank; then, the electric heating device 102 is horizontally inserted into the connecting pipe 103 from the outside until its tail abuts against the stepped ring 104; next, a radial seal is achieved between the middle of the electric heating device 102 and the inner wall of the connecting pipe 103 through the sealing member, and the sealing gasket 107 is installed between the tail of the device and the stepped ring 104 to form an end face seal; then, the right-angle pressure ring 105 is fitted onto the outside of the stepped ring 104, and the insertion rod 108 and...

During maintenance, the equipment can be pulled out simply by loosening the locking component from the outside, without having to enter the tank, thus solving the problems of inconvenient disassembly and maintenance, high safety risks, long operation cycle and high cost in the prior art.

[0025] Furthermore, the plurality of the supporting ribs 110 are fixedly connected to the connecting pipe 103 and the stepped ring 104 respectively, the conical ring platform 111 is fixedly connected to the right-angle pressure ring 105 and is located on the inner side wall of the right-angle pressure ring 105, and the conical ring platform 111 is in contact with the electric heating device 102.

[0026] In this embodiment, the support rib 110 is used to increase the connection strength at the connection between the connecting pipe 103 and the stepped ring 104, share the pressure borne by the stepped ring 104, and prevent the connection from breaking; the conical ring platform 111 is used to cooperate with the right-angle pressure ring 105 to press the electric heating device 102.

[0032] In this embodiment, during installation, the slider 118 is inserted into the groove 124 to fix the mounting ring 119, and then the electric heating device 102 is inserted horizontally so that the sealing ring 120 contacts the connecting pipe 103 and the electric heating device 102 respectively to form a radial seal and avoid leakage.

[0033] Furthermore, the support frame 121 is fixedly connected to the oil storage tank body 101 and is located below the oil storage tank body 101, the mounting plate 122 is fixedly connected to the support frame 121 and is located below the support frame 121, and the mounting plate 122 has mounting holes 125.

[0034] In this embodiment, the support frame 121 and the mounting plate 122 form a mounting bracket, which facilitates the use of the mounting holes 125 to insert pre-embedded bolts for locking and fixing, thereby improving the ease of installation of the oil storage tank body 101.

[0035] Furthermore, the connecting rib 123 is fixedly connected to the mounting plate 122 and the support frame 121 respectively.

[0036] In this embodiment, the connecting rib 123 can enhance the connection strength between the mounting plate 122 and the support frame 121, and extend the service life of the mounting plate 122 and the support frame 121.

[0038] In this embodiment, the concentration sensor 126 monitors the concentration of oil in the main body 101 of the oil storage tank in real time and transmits it to the terminal through the wireless transmitter 127, so that the staff can view it and control the electric heating device 102 to heat the oil inside.

[0039] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
