Description

Technical Field

[0001] This utility model belongs to the field of pipeline transportation technology, and in particular relates to a protective safety pipeline heating device. Background Technology

[0002] Some active pharmaceutical ingredient intermediates have high melting points, such as 45°C for one particular intermediate. However, in winter, when temperatures are low, the pipelines transporting these materials may solidify and become blocked after transport. Therefore, to avoid this problem, steam purging is currently the primary method for unblocking these blockages; however, this operation carries relatively high risks during on-site work. Utility Model Content

[0003] In view of this, the present invention aims to overcome the shortcomings of the above-mentioned problems in the prior art and proposes a protective safety pipeline heating device.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A protective safety pipeline heating device includes two arc-shaped connecting covers, which are fixed together to form a tubular structure. Each connecting cover includes an arc-shaped connecting plate and an arc-shaped cover plate disposed outside the connecting plate. A heating chamber is provided between the connecting plate and the cover plate, and a heating pipe is disposed inside the heating chamber.

[0006] Furthermore, the heating tube has a serpentine structure in the length direction and an arc-shaped structure protruding outward in the width direction. Multiple snap-fit ​​blocks are evenly fixed on the outer wall of the connecting plate. An arc-shaped groove is opened on the outer side of the snap-fit ​​block, and the heating tube is snapped into the arc-shaped groove at the corresponding position.

[0007] Furthermore, the connecting plate has vertical connecting strips extending outwards on both the upper and lower sides, and an L-shaped arc-shaped snap-fit ​​strip on one of the left and right sides of the connecting plate. Each connecting strip has a limiting protrusion along its length, and the limiting protrusion corresponds to the inside of the snap-fit ​​strip. One end of the cover plate corresponding to the snap-fit ​​strip is inserted into the inside of the snap-fit ​​strip, and the upper and lower sides are located outside the limiting protrusion. An L-shaped arc-shaped positioning strip is fixed between the other end of the connecting plate and the other end of the cover plate. The upper and lower edges of the inner sidewall of the cover plate abut against the corresponding limiting protrusion, and the left and right edges of the outer sidewall abut against the inner sidewalls of the snap-fit ​​strip and the positioning strip, respectively.

[0008] Furthermore, both ends of the positioning strip are provided with integrally formed fixing blocks on the side facing the snap-fit ​​strip, and the fixing blocks are provided with first through holes. One end of the connecting strip is provided with a second through hole corresponding to the first through hole, and the other end is provided with a third through hole. The two connecting plates are joined together, and the corresponding first through holes and second through holes on the two connecting plates are fixed together by bolt and nut pairs. The corresponding third through holes are also fixed together by bolt and nut pairs.

[0009] Furthermore, a groove is provided on the positioning strip corresponding to the explosion-proof power connector at the front end of the heating tube.

[0010] Furthermore, an insulation layer is wrapped around the outside of the tubular structure formed by the two connecting covers.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] As shown in the figure, a protective safety pipeline heating device includes two arc-shaped connecting covers, which are joined and fixed together to form a tubular structure. Each connecting cover includes an arc-shaped connecting plate 1 and an arc-shaped cover plate 2 disposed outside the connecting plate 1. A heating chamber is provided between the connecting plate 1 and the cover plate 2, and a heating pipe 3 is disposed within the heating chamber. In this embodiment, the two connecting covers are joined together to form a tubular structure, enclosing the pipeline within it. Heating is achieved through the heating pipe 3 within the connecting cover, ensuring that the material flowing inside the pipeline does not solidify. Furthermore, the temperature of the heating pipe 3 can be adjusted according to the melting point of the conveyed material, facilitating temperature adjustment and control.

[0026] The heating tube 3 has a serpentine structure in the length direction and an arc-shaped structure that protrudes outward in the width direction. Multiple snap-fit ​​blocks 104 are evenly fixed on the outer wall of the connecting plate 1. An arc-shaped groove 1041 is opened on the outer side of the snap-fit ​​block 104. The heating tube 3 is snapped into the arc-shaped groove 1041 at the corresponding position, thereby positioning the entire heating tube 3.

[0027] Connecting plates 1 have vertically extending connecting strips 101 on both the top and bottom sides. One side of the connecting plate 1 has an L-shaped arc-shaped snap-fit ​​strip 102. Each connecting strip 101 has a limiting protrusion 103 along its length, corresponding to the inside of the snap-fit ​​strip 102. One end of the cover plate 2 corresponding to the snap-fit ​​strip 102 is inserted into the inside of the snap-fit ​​strip 102, with its top and bottom sides located outside the limiting protrusion 103. An L-shaped arc-shaped positioning strip 4 is fixed between the other end of the connecting plate 1 and the other end of the cover plate 2. The upper and lower edges of the inner wall of the cover plate 2 abut against the corresponding limiting protrusion 103, and the left and right edges of the outer wall abut against the inner walls of the snap-fit ​​strip 102 and the positioning strip 4, respectively. In this embodiment, the cover plate 2 is positioned outside the connecting plate 1 by the snap-fit ​​strip 102, the limiting protrusion 103, and the positioning strip 4, facilitating the later disassembly and replacement of the internal heating tube 3. In this embodiment, the connecting strip 101, the snap-fit ​​strip 102, the limiting protrusion 103, and the connecting plate 1 are integrally formed or welded together.

[0028] Both ends of the positioning strip 4 are provided with integrally formed fixing blocks 401 facing the snap-fit ​​strip 102, and the fixing blocks 401 are provided with first through holes 402. One end of the connecting strip 101 is provided with a second through hole 105 corresponding to the first through hole 402, and the other end is provided with a third through hole 106. The two connecting plates 1 are joined together, and the corresponding first through holes 402 and second through holes 105 on the two connecting plates 1 are fixed together by bolt and nut pair 5. The corresponding third through holes 106 are also fixed together by bolt and nut pair 5.

[0029] A groove 403 is provided on the positioning strip 4 at the power explosion-proof connector at the front end of the heating tube 3 to facilitate the connection of the power explosion-proof connector.

[0030] An insulation layer (not shown in the figure) is wrapped around the outside of the tubular structure formed by the two connecting covers. In this embodiment, the insulation layer is made of rock wool, which has good fire resistance and stable insulation performance. When wrapping, the connecting strip 101 is also wrapped inside.

[0031] The working process of this embodiment is as follows:

[0032] When the heating device is installed on the pipeline, firstly, the heating tube 3 is snapped onto the outer wall of the connecting plate 1. Then, the cover plate 2 is initially positioned by the limiting protrusion 103 and the snap-fit ​​strip 102. Next, the two connecting parts are wrapped around the pipeline and initially connected at the third through hole 106 by the bolt and nut pair 5. Then, the positioning strip 4 on each side is installed at the other end of the connecting cover, and the positioning strip 4 and the corresponding connecting strip 101 on the two connecting covers are fixed together at the second through hole 105 by the bolt and nut pair 5. Finally, the bolt and nut pair 5 at the third through hole 106 is tightened.

[0033] In use, multiple heating devices can be installed on the pipeline according to its length, with a small distance between each pair of adjacent heating devices to allow space for the power cord of the heating tube 3 to exit. Connecting the power supply allows the heating tube 3 to heat the pipeline, ensuring that the internal temperature of the pipeline is isolated from the external environment and that the internal temperature is higher than the melting point of the material, thus ensuring smooth material transport.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
