Description

Technical Field

[0001] The utility model relates to the technical field of pipeline heating, in particular to a pipeline heating device. Background Art

[0002] When encountering low temperature weather, oil may solidify in the pipeline. In order to avoid pipeline blockage and prevent the impact on oil transportation, the pipeline needs to be heated. In the existing technology, an electromagnetic heating blanket can be used to cover the outside of the pipeline for heating. The electromagnetic heating blanket host converts industrial frequency electricity into a 20kHz high-frequency power supply. The constantly changing high-frequency magnetic field acts on the metal body of the pipeline through the heating blanket to generate eddy currents, causing the metal itself to heat up. Since the pipeline itself heats up, the heat energy is inside the pipeline, which is more conducive to the heating and thawing of the internal medium.

[0003] However, since the electromagnetic heating blanket is always in contact with the pipe during use, the steam generated by the pipe has no place to be discharged and can only pass through the electromagnetic heating blanket. When passing through the electromagnetic heating blanket, the steam will affect the coil in the electromagnetic heating blanket 1, thereby shortening the service life of the electromagnetic heating blanket. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a pipeline heating device.

[0005] The utility model proposes a pipeline heating device, comprising: a plurality of electromagnetic heating blankets, a wire, a control unit, and a plurality of groups of pad units. The plurality of electromagnetic heating blankets are sequentially connected in series through the wires and electrically connected to the control unit. The plurality of groups of pad units are fixed on the plurality of electromagnetic heating blankets in a one-to-one correspondence, and the pad units include a plurality of first pads that can be plastically deformed. The first pads are provided with a plurality of first through grooves penetrating along the width direction thereof, and the plurality of first through grooves are sequentially spaced along the length direction of the first pads.

[0006] Preferably, a groove for accommodating the wire is provided on the first pad strip and on the side away from the electromagnetic heating blanket. The groove extends along the length direction of the first pad strip and is connected to the first through groove. An opening for the wire to enter and exit is provided on the side of the first through groove away from the electromagnetic heating blanket.

[0007] Preferably, a plurality of groups of anti-skid units are fixed on the first pad strip, and the plurality of groups of anti-skid units are arranged one by one between the plurality of first through grooves, and the two anti-skid pads included in each group of anti-skid units are respectively located on both sides of the groove.

[0008] Preferably, the distance between opposite sides of two anti-slip pads included in each group of anti-slip units gradually decreases in the direction away from the first pad strip, and the maximum distance between opposite sides of the two anti-slip pads is less than or equal to the diameter of the wire, and the anti-slip pads can produce elastic deformation.

[0009] Preferably, the anti-slip mat is made of heat-insulating material.

[0011] The heating device proposed in the utility model heats the fluid in the pipeline by means of an electromagnetic heating blanket.

[0016] Reference Figure 1 , Figure 3 The utility model proposes a pipeline heating device, comprising: a plurality of electromagnetic heating blankets 1, a wire 2, a control unit 3, and a plurality of groups of pad units 4. The plurality of electromagnetic heating blankets 1 are sequentially connected in series through the wire 2 and electrically connected to the control unit 3. The plurality of groups of pad units 4 are fixed on the plurality of electromagnetic heating blankets 1 in a one-to-one correspondence, and the pad units 4 include a plurality of first pads 41 that can be plastically deformed. The first pads 41 are provided with a plurality of first through grooves 411 penetrating along the width direction thereof, and the plurality of first through grooves 411 are sequentially spaced along the length direction of the first pads 41.

[0017] When in use, the electromagnetic heating blanket 1 is wrapped around the pipe 5, and the first pad 41 is deformed and fits the outer wall of the pipe 5. Multiple electromagnetic heating blankets 1 can be placed at different positions of the pipe 5 at intervals, and the distance between the multiple electromagnetic heating blankets 1 can be adjusted according to specific heating requirements. The setting of the first pad 41 can also reserve a certain space between the electromagnetic heating blanket 1 and the outer wall of the pipe 5, so that the steam generated when the pipe 5 is heated can escape outward through the first through groove 411, avoiding the problem in the prior art that the electromagnetic heating blanket 1 is always in contact with the pipe 5, and the steam generated by the heated pipe 5 has no place to be discharged and can only pass through the electromagnetic heating blanket 1, thereby affecting the coil in the electromagnetic heating blanket 1.

[0018] In the above embodiment, when the distance between two adjacent electromagnetic heating blankets 1 is smaller than the length of the wire 2 , the wire 2 may sag due to gravity, and the drooping wire 2 is easily damaged by being gnawed by creatures such as mice.

[0019] In order to better protect the wire 2, a groove 412 for accommodating the wire 2 is provided on the first pad 41 and on the side away from the electromagnetic heating blanket 1. The groove 412 extends along the length direction of the first pad 41 and is connected to the first through groove 411. The first through groove 411 is provided with an opening for the wire 2 to enter and exit on the side away from the electromagnetic heating blanket 1. For details, refer to Figure 2 .

[0020] When in use, the excess part of the wire 2 is received in the groove 412 through the first through groove 411 and then led out through the first through groove 411. The excess wire 2 is received in the groove 412, which can not only protect the wire 2, but also shorten the exposed length of the wire 2 to prevent the wire 2 from sagging.

[0021] It should be further explained that, in order to increase the friction between the first pad 41 and the pipe 5, multiple groups of anti-slip units 42 are fixed on the first pad 41, and the multiple groups of anti-slip units 42 are arranged one by one between the multiple first through grooves 411, and the two anti-slip pads included in each group of anti-slip units 42 are respectively located on both sides of the groove 412.

[0022] The distance between the opposite sides of the two anti-slip pads included in each group of anti-slip units 42 gradually decreases in the direction away from the first pad strip 41, and the maximum distance between the opposite sides of the two anti-slip pads is less than or equal to the diameter of the wire 2. The anti-slip pads can produce elastic deformation. After the wire 2 enters the groove 412, the two anti-slip pads can support the wire 2, which can not only fix the wire 2 to a certain extent, but also ensure that there is a certain distance between the wire 2 located in the groove 412 and the outer wall of the pipe 5, thereby preventing the wire 2 from being attached to the outer wall of the pipe 5 and being heated.

[0023] The anti-slip mat is made of heat-insulating material.

[0024] In the above embodiment, in order to facilitate the installation of the present device, one end of the first pad strip 41 has a first connecting portion extending along its thickness direction, and the other end of the first pad strip 41 has a second connecting portion extending along its thickness direction. The first connecting portion and the second connecting portion are both provided with the same type of threaded holes, and the two threaded holes can be screwed to the same bolt.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
