Description

Technical Field

[0001] The utility model belongs to the technical field of chemical pipelines, and particularly relates to a chemical liquid transportation pipeline. Background Art

[0002] Anti-corrosion coatings are provided on the surface of chemical pipelines, which can effectively improve the anti-corrosion performance of the pipelines. However, in actual use, due to the mutual collision of pipelines during transportation, and when loading and unloading the pipelines from transport vehicles, the rust and burrs on the suspension hooks will also directly contact and slide on the surface coatings of the pipelines. There will be scratches and fine pinholes on the anti-corrosion coatings of some pipelines, which will lead to a decline in the insulation and anti-corrosion performance of the pipelines. After the pipelines are buried in the ground, anodic regions and cathodic regions will be formed in some parts of the pipelines. Due to the slight electrical conductivity of the soil, after a certain period of use, the anodic parts of the pipelines will be oxidized and corroded. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A chemical liquid conveying pipe includes a main conveying pipe 1. Suspension support orifice plates 2 are detachably connected to both sides of the main conveying pipe 1. The center of the inner wall of the suspension support orifice plate 2 is fixedly connected with an isolation support pipe 21. The inner wall of the suspension support orifice plate 2 is fixedly connected with an in-pipe support ring plate 3. The inner wall of the suspension support orifice plate 2 is fixedly connected with an outer-pipe support ring plate 4. The outer wall of the outer-pipe support ring plate 4 is fixedly connected with a friction limit washer 41.

[0017] In this implementation plan: After the main body 1 of the conveying pipeline is processed, the staff installs the suspension support orifice plate 2 at both ends of the main body 1 of the conveying pipeline to form a complete chemical liquid conveying pipeline product. When the pipeline needs to be shipped, the staff inserts the two hooks of the loading and unloading equipment into the two isolation support pipes 21 respectively. The hooks of the loading and unloading equipment drive the overall movement of the product by lifting the isolation support pipes 21 to transfer the pipeline product into the carriage of the transport vehicle. By installing the suspension support orifice plate 2, the isolation support pipes 21, and the inner support ring plate 3 of the pipeline at both ends of the main body 1 of the conveying pipeline, when the staff loads and unloads the main body 1 of the conveying pipeline, the hooks of the loading and unloading equipment will not directly contact the protective coating on the inner wall of the main body 1 of the conveying pipeline, avoiding damage to the coating on the inner wall of the main body 1 of the conveying pipeline caused by the rust and burrs of the hooks. When stacking the pipelines, the staff adjusts the alignment of the pipeline ends so that the positions of the outer support ring plates 4 and the friction limiting washers 41 installed on the adjacent pipelines correspond. The outer support ring plates 4 and the friction limiting washers 41 located below support the outer support ring plates 4 and the friction limiting washers 41 located above. The outer support ring plates 4 and the friction limiting washers 41 play a spacing role between adjacent pipelines, and the adjacent main bodies 1 of the conveying pipelines will not directly contact. When the vehicle body shakes during transportation, the adjacent main bodies 1 of the conveying pipelines will not collide with each other, avoiding damage to the outer coating of the main body 1 of the conveying pipeline caused by the collision between the adjacent main bodies 1 of the conveying pipelines. The device can protect the coating on the surface of the pipeline throughout the transportation process of the pipeline, avoiding damage to the coating and affecting the anti-corrosion performance of the pipeline itself. When installing the pipeline, the staff can remove the suspension support orifice plate 2 from the end of the main body 1 of the conveying pipeline.

[0018] The inner support ring plate 3 of the pipeline is located inside the main body 1 of the conveying pipeline. The side wall of the inner support ring plate 3 is fixedly connected with a protective washer 31. One side of the inner support ring plate 3 is fixedly connected with an inclined guiding ring plate 32, and the inclined guiding ring plate 32 is fixedly connected with the isolation support pipe 21; the inner support ring plate 3 and the protective washer 31 are inserted into the inner wall of the main body 1 of the conveying pipeline so that the inner support ring plate 3 and the protective washer 31 can support the main body 1 of the conveying pipeline, and the protective washer 31 is made of an elastic material with a smooth outer wall. Before inserting the protective washer 31 into the main body 1 of the conveying pipeline, the staff cleans the protective washer 31. The protective washer 31 directly contacts the inner wall of the main body 1 of the conveying pipeline. When lifting the main body 1 of the conveying pipeline, the protective washer 31 will not damage the coating on the inner wall of the main body 1 of the conveying pipeline. By setting the inclined guiding ring plate 32, a guiding effect can be achieved, enabling the inner support ring plate 3 to be inserted into the main body 1 of the conveying pipeline more smoothly without the staff spending time aligning the inner support ring plate 3 and the inner hole of the main body 1 of the conveying pipeline.

[0019] Four sets of outer support ring plates 4 of the pipeline are sleeved outside the main body 1 of the conveying pipeline, and there is a gap between the outer support ring plates 4 of the pipeline and the main body 1 of the conveying pipeline; the outer support ring plates 4 of the pipeline are located outside the main body 1 of the conveying pipeline. After the main body 1 of the conveying pipeline is stacked, the outer support ring plates 4 below support the outer support ring plates 4 above, and cooperate with the suspension support hole plate 2 and the inner support ring plate 3 of the pipeline to support the main body 1 of the conveying pipeline. The main body 1 of the conveying pipeline will not be in direct contact with the outer support ring plates 4 of the pipeline, and the edges of the outer support ring plates 4 of the pipeline will not cause indentation damage to the outer coating of the main body 1 of the conveying pipeline.

[0020] A turnover intercepting plate 5 is hinged to the side wall of the inclined guiding ring plate 32, and the turnover intercepting plate 5 blocks an opening on one side of the isolation support pipeline 21; by setting the turnover intercepting plate 5, the opening of the isolation support pipeline 21 can be blocked. When the main body 1 of the conveying pipeline is stacked, external impurities will not enter the main body 1 of the conveying pipeline, avoiding impurities from entering the gap between the inner support ring plate 3 of the pipeline and the main body 1 of the conveying pipeline. When the staff takes out the suspension support hole plate 2 and the inner support ring plate 3 of the pipeline, the impurities in the gap between the inner support ring plate 3 of the pipeline and the main body 1 of the conveying pipeline will not scratch the inner wall coating of the main body 1 of the conveying pipeline.

[0021] The top end of the turnover intercepting plate 5 is fixedly connected with a torsion spring rotating shaft 51, the torsion spring rotating shaft 51 is fixedly connected with the inclined guiding ring plate 32, and an elastic sealing gasket 52 is fixedly connected to the inner wall of the turnover intercepting plate 5. The elastic sealing gasket 52 is stuffed in the isolation support pipeline 21; by setting the torsion spring rotating shaft 51, it is convenient for the hinge of the turnover intercepting plate 5. When using a long inserting rod to lift the main body 1 of the conveying pipeline, the turnover intercepting plate 5 is squeezed and turned over by the long inserting rod and opened, and after the long inserting rod is taken out, the turnover intercepting plate 5 can automatically turn over and block the isolation support pipeline 21 again. By setting the elastic sealing gasket 52, the sealing effect of the turnover intercepting plate 5 on the opening of the isolation support pipeline 21 can be improved.

[0022] Working principle and usage process of the utility model: After the main body 1 of the conveying pipeline is processed, the staff installs the suspension support orifice plate 2 at both ends of the main body 1 of the conveying pipeline to form a complete chemical liquid conveying pipeline product. When the pipeline needs to be shipped, the staff inserts the two hooks of the loading and unloading equipment into the two isolation support pipelines 21 respectively. The hooks of the loading and unloading equipment drive the whole product to move by lifting the isolation support pipeline 21, so as to transfer the pipeline product into the carriage of the transport vehicle. When loading and unloading the main body 1 of the conveying pipeline, the hooks of the loading and unloading equipment will not directly contact the protective coating on the inner wall of the main body 1 of the conveying pipeline, avoiding damage to the coating on the inner wall of the main body 1 of the conveying pipeline caused by the rust and burrs of the hooks. When stacking the pipelines, the staff adjusts the alignment of the pipeline ends so that the positions of the pipeline outer support ring plates 4 and the friction limiting washers 41 installed on the adjacent pipelines correspond. The pipeline outer support ring plates 4 and the friction limiting washers 41 located below support the pipeline outer support ring plates 4 and the friction limiting washers 41 located above. The pipeline outer support ring plates 4 and the friction limiting washers 41 play a role of spacing between adjacent pipelines, and the adjacent main bodies 1 of the conveying pipelines will not directly contact. When the vehicle body shakes during transportation, the adjacent main bodies 1 of the conveying pipelines will not collide, and the outer coating of the main body 1 of the conveying pipeline will not be damaged due to collision.
