DETAILED DESCRIPTION

[0014] In order to make the technical problems, technical solutions and beneficial effects of the utility model to be solved more clear and obvious, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0015] Reference Figure 1 The embodiment includes a metal pipe 1, a heating coil 10, a plug removal coil 9, a distribution box 3, a temperature transmitter 8, a pressure transmitter 7 and a data acquisition controller 4.

[0016] The heating coil 10 and the plug removal coil 9 are electrically connected with the distribution box 3 respectively.

[0017] The heating coil 10 is wound on the metal pipe 1. When heating normally, the electromagnetic controller in the multi-stage high-frequency distribution box 3 converts 220V, 50 / 60Hz alternating current into direct current, and then converts the direct current into high-frequency high-voltage electricity with a frequency of 20-40KHz. The high-speed changing high-frequency high-voltage current flowing through the heating coil 10 generates a high-speed changing alternating magnetic field. When the magnetic force lines in the magnetic field pass through the metal pipe 1, a large number of small eddy currents are generated in the metal pipe 1, so that the metal pipe 1 itself generates high-speed heat, thereby heating the liquid in the metal pipe 1. After the liquid passes through the device, the temperature of the liquid is raised, the molecules are ordered, the viscosity is reduced, and the formation of crystal nucleus of the liquid is effectively inhibited, so that the liquid is not easy to scale.

[0018] The deblocking coil 9 is wound on the metal pipe 1. When deblocking is needed, the electromagnetic controller in the multi-stage high-frequency distribution box 3 outputs a group of higher frequency high-voltage electricity. The high-speed changing high-frequency high-voltage current flowing through the deblocking coil 9 generates a high-speed changing alternating magnetic field, thereby further heating the liquid in the metal pipe 1 and realizing the deblocking function.

[0019] The heating coil 10 is located upstream of the deblocking coil 9. Since the usual blockage occurs downstream of the metal pipe 1, the deblocking coil 9 is arranged downstream of the heating coil 10.

[0020] The temperature transmitter 8 is installed on the metal pipe 1 to detect the temperature of the liquid in the metal pipe 1. The temperature transmitter 8 and the distribution box 3 are electrically connected to the data acquisition controller 4, and the temperature transmitter 8 transmits the temperature signal to the data acquisition controller 4. The pressure transmitter 7 is installed on the metal pipe 1 to detect the pressure value in the metal pipe 1. The pressure transmitter 7 is electrically connected to the data acquisition controller 4 to transmit the pressure value detected by the pressure transmitter 7 to the data acquisition controller 4. When the pressure transmitter 7 or the temperature transmitter 8 has an abnormal value, an alarm is given to remind the operator whether deblocking is needed.

[0021] One metal pipe 1 is provided with at least two temperature transmitters 8 and two pressure transmitters 7. One temperature transmitter 8 and one pressure transmitter 7 are arranged at the upper part of the metal pipe 1, and one temperature transmitter 8 and one pressure transmitter 7 are arranged at the lower part of the metal pipe 1.

[0022] The excitation pipe heating and deblocking device further comprises a dry burning detector 2 installed on the metal pipe 1 to detect whether there is dry burning in the metal pipe 1. The dry burning detector 2 is electrically connected to the data acquisition controller 4 to transmit the detection result of the dry burning detector 2 to the data acquisition controller 4. When there is indeed dry burning in the metal pipe 1, the dry burning detector 2 transmits a signal to the data acquisition controller 4, and the data acquisition controller 4 sends an instruction to cut off the power supply of the heating coil 10 and the deblocking coil 9 by the distribution box 3.

[0023] The excitation pipeline heating and plugging removal device further comprises a man-machine interface 6, which is in communication connection with the data acquisition controller 4. The man-machine interface 6 is provided with inlet and outlet pressure display, inlet and outlet temperature display, voltage and current display, and outlet temperature setting function, the temperature control temperature is accurate to absolute value 1℃, which is convenient for users to observe the equipment running state. The outlet temperature of the effective control device is effectively controlled.

[0024] The excitation pipeline heating and plugging removal device further comprises a data wireless transmission module 5, which is in communication connection with the data acquisition controller 4. When the data needs to be remotely transmitted, the data is uploaded to the cloud through the data wireless transmission module 5, and then transmitted to the remote PC client 11 and the mobile client 12 through GPRS, so as to facilitate digital management and intelligent management.

[0025] In addition, the device adopts a spark-proof explosion-proof control element to ensure safe production.

[0026] In summary, the device has the characteristics of fast heating speed, high thermal efficiency, no spark during normal operation of the whole machine, meets the requirements of national special explosion-proof electrical appliances, and is suitable for rapid heating of crude oil pipelines.
