Description

Technical Field

[0001] The present invention relates to the technical field of pipeline heating, in particular to an electric heating structure for pipelines in a mixing station. Background Art

[0002] The conventional method for conveying water and additives in mixing plants is to insulate the pipes with a polyurethane rigid foam and a protective covering, but this method is not suitable for cold regions. Existing patent CN219242956U discloses a pipe heating device comprising a material conveying pipe, the outer surface of which is provided with a plurality of first and second electric heating tapes located in a straight line, the adjacent ends of which are provided with wiring devices, and the first and second electric heating tapes are electrically connected via the wiring devices; the outer surface of the material conveying pipe is provided with a plurality of annular fixing rings, and the connection between the fixing rings and the first and second electric heating tapes is fixedly connected with a clip, and the first and second electric heating tapes are embedded in the inner cavity of the clip and clipped with the clip.

[0003] Although the electric heating tape of the above-mentioned heating device can be fixed to the outer surface of the conveying pipe by the fixing ring to heat the conveying pipe, the size of the clip on the fixing ring cannot be adjusted. Each fixing ring can only be used with one specification of electric heating tape. However, in actual field applications, electric heating tapes of different specifications are often replaced according to heating requirements. For example, the electric heating tape will become wider after adding an electric heating cable, or it may be replaced with an electric heating tape of a different shape, etc. The fixing ring and clip of the above-mentioned heating device cannot be applied to electric heating tapes of different specifications and shapes. Corresponding fixing rings and clips must be specially made to fix the electric heating tape on the conveying pipe. The fixing rings and clips are relatively limited in use and also increase the production cost. Summary of the Invention

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The present invention adopts two split fixing blocks to fix the electric heating tape. The distance between the two fixing blocks is adjusted according to the specifications and shapes of the electric heating tape to adapt to different types of electric heating tapes, thereby improving the utilization rate of the auxiliary fixing frame and reducing the production cost.

[0008] Furthermore, the preferred embodiment of the present invention is:

[0009] The two fixed blocks are rectangular blocks respectively. Arc grooves are respectively provided on one side of the two fixed blocks close to the pipe body, and the two arc grooves are arranged opposite to each other up and down.

[0010] Fixed connecting frames are respectively provided on the side elevations of the two fixed blocks. The two fixed connecting frames are connected by a connecting wire, and the connecting wire cooperates with the fixing ring to fix the electric heating tape.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0020] An electric heating structure for mixing station pipelines, such as Figure 1 As shown, it is mainly composed of a pipe body 1, an electric heating cable 4 and an auxiliary fixing frame 2. The auxiliary fixing frame 2 is made of silicon carbide and has good wear resistance.

[0021] like Figure 2 As shown, the auxiliary fixing frame 2 is composed of two upper and lower fixed blocks 21. The two fixed blocks 21 are rectangular blocks. The two fixed blocks 21 are respectively provided with arc grooves 211 on one side close to the pipe body 1, and the two arc grooves 211 are arranged opposite to each other up and down. The electric heating tape 4 is placed in the two arc grooves 211, and the two fixed blocks 21 fix and limit the electric heating tape 4.

[0022] A fixed connecting frame 22 is respectively provided on the side facades of the two fixed blocks 21. The two fixed connecting frames 22 are connected by a connecting wire 23. The connecting wire 23 in this embodiment is a copper wire. When connected, multiple groups of copper wires are wound side by side between the two groups of fixed connecting frames 23, which is convenient for increasing the fixing effect of the electric heating tape 4 so that it will not loosen after long-term use.

[0023] Auxiliary connecting blocks 24 are respectively installed on the top of the upper fixed block 21 and the bottom of the lower fixed block 21. The left side of the auxiliary connecting block 24 extends outward to the outside of the fixed block 21, and each extended end of the auxiliary connecting block 24 is respectively provided with a slot 241. The fixing ring 3 passes through the two slots 241 and is connected to the pipe body 1.

[0024] In this embodiment, the fixing ring 3 is also a copper wire. The copper wire passes through the two slots 241 and is then wrapped around the outside of the pipe body 1 to fix the auxiliary fixing frame 2 .

[0025] A thermal insulation layer 5 is wrapped around the outside of the pipe body 1 and the electric heating tape 4 to prevent heat loss.

[0026] When this embodiment is used, the electric heating tape 4 is laid on one side of the pipe body 1 along the length direction of the pipe body 1. After determining the spacing of the auxiliary fixing frame 5 on the pipe body 1, the installation is started; the two fixing blocks 21 are installed on the fixing ring 3, and the two fixing blocks 21 are simply connected by a connecting line 23 (the spacing between the two fixing blocks 21 is not adjusted at this time. The simple connection is to prevent the two fixing blocks 21 from being separated and easy to operate). The electric heating tape 4 is passed through the inner side of the fixing ring 3 into the arc groove 211 of the two fixing blocks 21, and then the fixing ring 3 is connected to the pipe body 1. When connecting, pay attention to adjusting the spacing between the two fixing blocks 21 according to the size of the electric heating tape 4 so that the electric heating tape 4 is not separated. The upper and lower surfaces of the heating tape 4 just fit tightly against the arc groove 211 on their respective sides, and the heating tape 4 fits tightly against the surface of the pipe body 1; then the two fixing blocks 21 and the heating tape 4 are fixed to the pipe body 1 through the fixing ring 3. At this time, the heating tape 4 is preliminarily fixed to the pipe body 1 through the two fixing blocks 21 and the fixing ring 3; the connecting wire 23 passes through the two fixing connecting frames 22 and is wound in parallel between the two groups of fixing connecting pieces 22 to fix the heating tape 4 for a second time; after all the fixing auxiliary frames 2 on the pipe body 1 are installed, a layer of insulation layer 5 is wrapped around the outside of the pipe body 1 and the heating tape 4 (the part that wraps the fixing auxiliary frames) to prevent heat loss.

[0027] This structure can be adjusted according to the shape and specifications of the electric heating cable, making it more widely used. The electric heating cable and the auxiliary fixing frame are doubly fixed by the fixing ring and the connecting wire to prevent loosening during long-term use. This structure has a better fixing effect, reduces the wear and tear caused by long-term use, and reduces maintenance costs.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
