Embodiment 1

[0043] Such as figure 1 As shown, this embodiment discloses a heat exchange and heat preservation pipeline structure for plastic pipe processing, including waste heat collection and heat preservation pipelines, first cooling heat exchange pipelines, second cooling heat exchange pipelines, waste heat transport heat preservation pipelines, return material heat preservation pipelines, A reaction kettle, a first water-cooled tank assembly, a second water-cooled tank assembly, a centrifugal separation device, and a still.

[0044] The first water-cooling tank assembly includes several first water-cooling tanks, and the second water-cooling tank assembly includes several second water-cooling tanks.

[0045] The feed end of the waste heat collection and heat preservation pipeline is connected with the steam outlet of the distillation kettle, and the discharge end of the waste heat collection and heat preservation pipe is divided into three branches. Wherein, the first branch is resp...

Embodiment 2

[0061] Such as figure 2 As shown, the difference between this embodiment and the above-mentioned embodiments is that the heat exchange and heat preservation pipeline structure also includes a third cooling heat exchange pipeline, and after the first cooling heat exchange pipeline, the second cooling heat exchange pipeline and the waste heat transport and heat preservation pipeline are connected in parallel, It is connected in series with the third cooling heat exchange pipeline.

[0062] The third cooling heat exchange pipe is arranged in the third water-cooling tank assembly, and the third water-cooling tank assembly includes a plurality of third water-cooling tanks, which are arranged sequentially from front to back according to the cooling sequence. The number of the third cooling heat exchange pipes is multiple and connected in parallel with each other, and each third cooling heat exchange pipe extends from the starting end of the third water cooling tank body at the star...

Embodiment 3

[0065] Such as Figure 3-4 As shown, the difference between this embodiment and the above-mentioned embodiments is that the openings of all the water-cooling tanks in this embodiment are upward, and corresponding cooling and heat exchange devices are provided on the two side inner walls and the bottom wall of each water-cooling tank. pipeline. The front and rear ends of all water-cooling tanks are provided with material guide ports 1004, which are used for pipes to pass through and out of the tanks.

[0066] In some embodiments, a sump 1005 is provided at the bottom of each set of water-cooling tank assemblies, and the sump 1005 communicates with the corresponding water-cooling tank through pipes 1006 or extends above the opening of the corresponding water-cooling tank. In the present invention, the contact between each heat exchange pipe and the corresponding tank body is sealed by a sealing member.

[0067] Because there is a gap between the pipe material and the material ...

Abstract

The invention discloses a heat exchange thermal insulation pipeline structure, which consists of a waste heat collection and thermal insulation pipeline, first cooling and heat exchange pipelines, second cooling and heat exchange pipelines, a waste heat conveying and thermal insulation pipeline and a return material thermal insulation pipeline. The waste heat collection and thermal insulation pipeline is in series connection with the first cooling and heat exchange pipelines, the second cooling and heat exchange pipelines, and the waste heat conveying and thermal insulation pipeline respectively, the first cooling and heat exchange pipelines and the second cooling and heat exchange pipelines are connected in parallel and then are connected to the waste heat conveying and thermal insulationpipeline in parallel, and then the connected pipelines are connected to the return material thermal insulation pipeline in series through a centrifugal separation device. The heat exchange thermal insulation pipeline structure provided by the invention has the advantages of full use of factory production waste heat, gradual cooling of pipes with the waste heat, and improvement of pipe strength.

Description

technical field [0001] The invention relates to the technical field of pipe materials, in particular to a heat exchange and heat preservation pipeline structure. Background technique [0002] The processing technology of the plastic pipe in the prior art usually includes the following steps: mixing, extruding, cooling, pulling, cutting and so on. Among them, compounding is to mix resin with other additives; extrusion is to melt and extrude the mixed material through an extruder; traction is to use the formed pipe body to continuously and automatically cool and harden the The pipe is led out from the machine head, and the frequency conversion speed is adjusted, and the finished product is cut. [0003] At present, air cooling or water cooling are mostly used for cooling. Among them, air cooling is to blow air on the surface of the pipe body through the action of the blower to speed up the exchange rate of the air around the pipe body, thereby improving the cooling efficienc...
