[0023] Example 1: See Figures 1 to 3 The utility model provides an oil injection pipeline heating device, comprising a heating pipe 2 arranged outside an oil supply pipeline 1, the heating pipe 2 is in an "n" shape, and two vertical pipes of the heating pipe 2 are respectively located on both sides of the oil supply pipeline 1;

[0024] The heating tube 2 is preferably a copper tube, which has the characteristics of high pressure resistance, corrosion resistance, long service life, good thermal conductivity, and easy shaping, and is easy to process;

[0025] The length of the vertical pipe of the heating pipe 2 is determined according to the length of the oil supply pipeline 1, so as to ensure that the heating pipe 2 can heat the oil supply pipeline 1;

[0026] One end of the heating tube 2 is the inlet end of the heat source, and the other end is the outlet end of the heat source.

[0027] The heating tube 2 can also be in a straight line shape. The heating tube 2 is placed on one side of the oil supply pipeline 1. The lower end of the heating tube 2 is the inlet end of the heat source, and the upper end is the outlet end of the heat source. This design can heat the oil supply pipeline while reducing the volume of the device as much as possible, which is more suitable for use in small spaces.

[0028] Heat preservation cotton is arranged on the outside of the heating pipe 2 and the oil supply pipeline 1, and aluminum foil tape is wrapped around the outside of the heat preservation cotton.

[0029] The thermal insulation cotton has the characteristics of low thermal conductivity and good thermal insulation effect, which improves the thermal insulation and minimizes the heat loss of the pipeline.

[0030] The aluminum foil tape is adhered to the outer surface of the thermal insulation cotton, and the connection is firm and not easy to fall off. The thickness of the aluminum foil tape is 0.2-0.5mm, which has the function of heat insulation and heat preservation, and the effect is good.

[0031] A valve 13 is fixedly provided at each end of the heating pipe 2 . When the temperature is high in summer, the valve 13 can be closed to prevent heat energy from entering the heating pipe 2 and continuously heating the oil supply pipeline 1 .

[0032] When the utility model is used, the inlet end of the heating pipe 2 is connected to a heat source, which includes steam or hot water, etc. The heat source is selected according to the actual situation of the factory, and then the thermal insulation cotton and the aluminum foil tape are respectively wrapped around the outside of the heating pipe 2 and the oil supply pipeline 1. In the cold winter season, the factory waste heat heats the oil supply pipeline 1 through the heating pipe 2 to avoid ice freezing on the oil supply pipeline, which may cause pipeline blockage.

[0033] Embodiment 2: Based on Embodiment 1, the vertical portion of each heating tube 2 is fixedly connected to the oil supply pipeline 1 through a plurality of fixing clamps 3;

[0034] The fixing clamp 3 includes a movable clamp plate 4 and a fixed clamp plate 5 which are arranged opposite to each other. A semicircular groove 6 is respectively formed at two ends of the movable clamp plate 4 and the fixed clamp plate 5 on the opposite side.

[0035] A slider 7 with a trapezoidal cross section is provided in the middle of the plate body of the movable clamp plate 4, and the end of the slider 7 facing the fixed clamp plate 5 is a large end;

[0036] The fixed splint 5 opens a slide groove 8 with a trapezoidal cross section toward the middle of the movable splint 4 , the small end of the slide groove 8 faces the movable splint 4 , the slide groove 8 corresponds to the slider 7 , and the movable splint 4 is slidably connected to the slider 7 through the slide groove 8 .

[0037] When the fixing clamp 3 is in use, the vertical part of the heating tube 2 and the oil supply pipeline 1 are placed in the groove 6 of the fixed clamp plate 5 and the movable clamp plate 4, and the slider 7 is inserted into the slide groove 8. Under the action of the slide groove and the slider, the movable clamp plate 4 and the fixed clamp plate 5 form a whole, thereby fixing the heating tube 2 and the oil supply pipeline 1.

[0038] A through-limiting groove 9 is provided in the middle of the fixed clamping plate 5 , a limit wrench 10 is rotatably arranged in the limit groove 9 , and a protrusion 12 is fixedly arranged at one end of the limit wrench 10 close to the rotating shaft of the limit wrench 10 .

[0039] After the movable splint 4 and the fixed splint 5 are aligned, the installer rotates the limit wrench 10 so that the protrusion 11 of the limit wrench 10 abuts against the slider 7, applies a certain force to the slider 7, and the slider 7 fits tightly against the slide groove 8, thereby fixing the movable splint 4 and the fixed splint 5.

[0040] When the fixing clamp 3 needs to be removed, the movable clamp plate 4 and the fixed clamp plate 5 can be separated by simply rotating the limit wrench 10 .

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
