Description

Technical Field

[0001] This utility model belongs to the field of pipeline processing technology, specifically referring to a heating device for pipeline processing. Background Technology

[0002] In the fields of petrochemicals, energy transmission, and manufacturing, pipeline heating devices are key equipment to ensure the smooth operation of production processes. Their performance directly affects the flowability of the medium inside the pipeline, reaction efficiency, and the quality of the final product.

[0003] Traditional heating devices mostly use resistance heating and heat conduction oil jacket heating. Due to structural limitations, they are prone to uneven heating, which can lead to "yin-yang" defects on the cross-section of the tube blank. In addition, they lack an active cooling mechanism and rely solely on natural cooling. The uneven temperature distribution formed during natural cooling can cause internal stress, deformation, or even cracks in the pipe. The cooling rate is slow and cannot be adjusted. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a heating device for pipe processing, which effectively solves the problem that the existing pipe heating devices using resistance heating and heat conduction heating methods are prone to uneven heating of the pipe, and also solves the problem that the natural cooling speed is slow and uneven cooling can easily cause deformation and cracks.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a heating device for pipe processing, including a cooling spray box and a water storage tank fixed to the bottom of the cooling spray box. A heating coil is fixed on the side wall at the front end of the cooling spray box, and the heating coil is coaxially arranged with the cooling spray box. A base plate is fixed to the bottom of both ends of the water storage tank. Several guide rollers are evenly distributed on the base plate, and a rotating drive roller is provided between the guide rollers and the cooling spray box. The rotating drive roller is set at an angle to the guide rollers. Circular fans are rotatably connected to both ends inside the cooling spray box; the cooling spray... The cooling tank is equipped with a spray cooling mechanism, which includes spray pipes evenly distributed in a ring along the inner wall of the cooling spray tank. The ends of each group of spray pipes are connected by two annular connecting pipes. A water inlet pipe is fixed on the side wall of the cooling spray tank and is connected to the connecting pipe. Several nozzles are evenly distributed on the spray pipes. A dust removal mechanism is provided on the bottom plate at the front end of the water storage tank. The dust removal mechanism consists of a dust cover and a brush roller. The dust cover is fixed on the bottom plate and located above the guide roller. The brush roller is rotatably connected to the inner wall of the dust cover and is arranged parallel to the top of the guide roller.

[0006] As an improvement to this solution, the ring fan is composed of an inner ring and an outer ring arranged coaxially, and the inner ring and the outer ring are fixedly connected by a number of guide vanes. At the same time, the guide vanes are evenly distributed along the circumference.

[0007] As an improvement to this solution, the outer ring is rotatably connected to the inner wall of the cooling spray box, and an outer gear ring is fixed on the outer wall of the outer ring. A fixed cover is fixed at the upper end of the cooling spray box, and a drive gear is rotatably connected inside the fixed cover. The drive gear meshes with the outer gear ring. A reduction motor is fixed at the upper end of the cooling spray box, and the output shaft of the reduction motor passes through the fixed cover and is connected to the drive gear.

[0008] As an improvement to this solution, a dust collection hood is fixed on the side wall of the dust cover, a dust collection bucket is connected to the lower end of the dust collection hood, and a dust suction fan is provided at the connection between the dust collection bucket and the dust collection hood.

[0009] As an improvement to this solution, a drain plate is provided at the bottom of the cooling spray box, and several through holes are evenly distributed on the drain plate. The cooling spray box is connected to the water storage tank through the through holes, and a drain pipe is provided on the side wall of the water storage tank.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows: 1. Equipped with guide rollers and inclined rotating drive rollers, it can realize rotation during pipeline transportation. Combined with heating coils, it can achieve uniform heating of the pipeline and improve pipeline quality. 2. The spray cooling mechanism uses cooling water and spray pipes evenly distributed along the circumference, combined with rotating pipes, to quickly and evenly cool down the heated pipes. 3. Circular fans are installed at both ends of the cooling spray box to maintain airflow inside the cooling spray box, thereby timely removing water vapor generated when the cooling water comes into contact with the pipes. At the same time, they can carry away the heat inside the box and assist in cooling the pipes. 4. A dust removal mechanism is installed at the front end of the entire equipment to remove dust, oil, and other contaminants that adhere to the surface of the pipeline during production and storage, thereby avoiding uneven heating of the pipeline during magnetic induction heating and further improving the quality of the pipeline.

The rotating drive roller 6 is arranged at an angle with the guide rollers 5. A ring fan 7 is rotatably connected to both ends inside the cooling spray box 1. like Figure 8The ring fan 7 is composed of an inner ring 17 and an outer ring 18 arranged coaxially, and the inner ring 17 and the outer ring 18 are fixedly connected by a number of guide vanes 19. Meanwhile, the guide vanes 19 are evenly distributed along the circumference.

[0017] like Figure 4 and Figure 7 As shown, the cooling spray box 1 is equipped with a spray cooling mechanism 8. The spray cooling mechanism 8 includes spray pipes 9 evenly distributed in a ring along the inner wall of the cooling spray box 1. The ends of each group of spray pipes 9 are connected through two annular connecting pipes 10. A water inlet pipe 11 is fixed on the side wall of the cooling spray box 1 and is connected to the connecting pipe 10. Several nozzles 12 are evenly distributed on the spray pipes 9.

[0018] like Figure 5 A dust removal mechanism 13 is provided on the bottom plate 4 at the front end of the water storage tank 2. The dust removal mechanism 13 consists of a dust cover 14 and a brush roller 16. The dust cover 14 is fixed on the bottom plate 4 and located on the upper side of the guide roller 5. The brush roller 16 is rotatably connected to the inner wall of the dust cover 14 and is arranged parallel to the upper side of the guide roller 5.

A dust collection bucket 25 is connected to the lower end of the dust collection hood 15, and a dust suction fan 24 is provided at the connection between the dust collection bucket 25 and the dust collection hood 15.

[0019] like Figure 6 The outer ring 18 is rotatably connected to the inner wall of the cooling spray box 1, and an outer gear ring 20 is fixed on the outer wall of the outer ring 18. A fixed cover 21 is fixed at the upper end of the cooling spray box 1. A drive gear 22 is rotatably connected inside the fixed cover 21, and the drive gear 22 meshes with the outer gear ring 20.
