Description
Technical Field
The invention relates to the technical field of corrosion prevention of steel pipes, in particular to processing equipment for plastic dipping inside and outside a steel pipe.
Background
Metal corrosion causes serious economic losses to mankind. Foreign data indicate that about 3 tons of steel products are scrapped due to corrosion per 10 tons of steel products. Therefore, in order to reduce the economic loss caused by corrosion, new corrosion prevention techniques have been continuously studied and searched.
In order to prevent corrosion, methods of glass fiber reinforced plastics, lining rubber, coating various anticorrosive coatings, stainless steel and the like appear in the prior art for many years. However, there are also disadvantages such as insufficient strength of the glass fiber reinforced plastic to be easily deformed by the long-term irradiation of ultraviolet rays. The traditional plastic lining can only be a single-layer lining, and cannot realize internal and external corrosion prevention, and the outer wall is usually coated with paint by the traditional method. The traditional lining plastic is processed by a loose lining or tight lining process, bubbles are easy to remain, flanges need to be flanged, the strength is not enough, the adhesive force is not strong, and the flanges are easy to fall off. The traditional lining rubber is adhered by rubber plates, and the rubber plates are provided with seams, so that air bubbles are easy to store and fall off easily. Stainless steel pipelines need to be welded on site. The method of adopting stainless steel pipeline is high in price by combining the material and the installation cost. Electrostatic spraying is inefficient, thin, non-ideal in corrosion protection, and expensive in process equipment. The surface area of the steel pipe is large, the small number of the steel pipe is 4-10 square meters, the surface of the large pipe diameter can reach more than 30 square meters, if an electrostatic spraying method is adopted, more than half an hour is needed, and the pipeline can be rapidly cooled to generate pinholes.

step two, inserting the duplex track rod 5 into the steel pipe through a sliding support 6 in the same axial direction, and sequentially arranging an inner laser rust removal assembly 7b and an inner plastic-impregnated assembly 8b at a first working end and a second working end of the duplex track rod 5, so that the inner laser rust removal assembly 7b and the inner laser rust removal assembly 7b face the inner periphery of the steel pipe;
step three, starting a first servo motor 1h and a second placing rack 2 to enable the steel pipe to coaxially rotate on the placing rack;
step four, starting the heating plate 3a to uniformly heat the steel pipe suspended at the top of the material bearing hopper 3 to a preset temperature;
step five, starting the duplex rail car 4 and the second servo motor 5e to enable an outer laser rust removal assembly 7a and an inner laser rust removal assembly 7b which are arranged at the first working ends of the duplex rail car 4 and the duplex rail rod 5 to remove rust on the outer circumferential surface and the inner circumferential surface of the steel pipe, so that after plastic dipping, an oxide layer and a plastic layer fall off together to enable the plastic dipping to be uneven or generate bubbles; the outer plastic-dipped components 8a and 9b0 arranged at the second working ends of the duplex track car 4 and the duplex track rod 5 are respectively subjected to plastic dipping treatment with the outer circumferential surface and the inner circumferential surface of the steel pipe subjected to rust removal treatment, and the steel pipe rotates coaxially all the time in the plastic dipping process, so that a plastic layer can effectively and uniformly cover the inner circumference and the outer circumference of the steel pipe;
step six, the waste plastics generated in the plastic dipping process fall into the material bearing hopper 3 with the wide opening upward under the action of gravity, and the temperature of the two sides of the material bearing hopper 3 is relatively high, so that the waste plastics are prevented from being condensed and adhered in the material bearing hopper 3, the liquid waste plastics are concentrated at the bottom end inside the material bearing hopper 3, and the liquid waste plastics are convenient to recycle.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
