Abstract
The invention relates to a carbon fiber casting type polyurethane hollow paraffin removal ball, and belongs to the technical field of chemical product manufacturing. The method is mainly technically characterized in that spherical foam is placed into a customized spherical die and poured into a carbon fiber spherical body, and a layer of polyurethane is wrapped on the periphery of the carbon fiber spherical body. The invention has the advantages of reasonable structural design, low manufacturing cost, simple preparation process, high product strength, long service life, high dredging efficiency and easy collection. The spherical foam is subjected to a cluster shrinkage phenomenon in a high-temperature petroleum environment, a cavity part is generated in the carbon fiber spherical body, so that the paraffin removal ball can float on the surface of petroleum, and the condition that the paraffin removal ball is difficult to salvage or cannot be found is avoided.
Description
Technical Field
The invention relates to a hollow paraffin removal ball for dredging a petroleum pipeline, in particular to a carbon fiber casting type polyurethane hollow paraffin removal ball, and belongs to the technical field of chemical product manufacturing in industry.
Background
The existing paraffin removal ball is solid in structure, is made of rubber materials, is high in density, is prone to sinking to the bottom of liquid when running in a crude oil pipeline, cannot float on the water surface, and sinks due to being solid, and is difficult to salvage or even invisible. Aiming at the requirement that the paraffin removal ball can float on the water surface, the existing paraffin removal ball with a solid structure needs to be researched, and the paraffin removal ball which has the advantages of lighter specific gravity than water and petroleum, higher strength and long service life and can float on the petroleum is required to be manufactured and used for dredging wax and scale in the petroleum pipeline and improving the flow of the petroleum pipeline.
Disclosure of Invention
The invention aims to solve the problems that the existing paraffin removal ball is unreasonable in structural design, solid in structure, and often sinks when in use, cannot float on the water surface, and is difficult to salvage and even invisible, so that a new technical scheme is provided.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
the utility model provides a hollow paraffin removal ball of carbon fiber casting type polyurethane which characterized by: carbon fibers are wrapped outside the spherical foam (1), and a layer of polyurethane is arranged outside the carbon fibers; and placing the spherical foam into a customized spherical mold, pouring into a carbon fiber spherical body, and wrapping a layer of polyurethane on the periphery of the carbon fiber spherical body.
Putting the carbon fiber spherical body into a customized spherical body mold, and pouring polyurethane to wrap a layer of polyurethane on the periphery of the spherical body, wherein the polyurethane is formed by polymerizing isocyanate monomers and hydroxyl compounds.
On the basis of a carbon fiber sphere, a mold and pouring process flow is adopted, the customized spherical mold is put into the mold and then is closed, and polyurethane is poured, so that the carbon fiber pouring type polyurethane paraffin removal ball is obtained. The product produced by the invention solves the problem that the customers are difficult to salvage in the using process in the prior art.
Compared with the prior art, the invention has the advantages that: structural design is reasonable, low in manufacturing cost, and product strength is big, and light in weight can not sink in the oil bottom, long service life, and the mediation is efficient, easily collects. The hollow cavity part in the carbon fiber casting polyurethane can be ensured, the carbon fiber casting polyurethane can float on the water surface, and the situation that fishing is difficult or finding is invisible can not occur.

FIG. 1 is a schematic diagram of the overall structure of an embodiment of the present invention.
Detailed Description
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown and described, and in which it is to be understood that the described embodiments are merely illustrative of the principles of the invention and that it is not restrictive.
A carbon fiber casting type polyurethane hollow paraffin removal ball is a hollow paraffin removal ball capable of dredging wax and scale in a petroleum pipeline, the conventional paraffin removal ball is solid and has a relatively high density, and the paraffin removal ball is easy to sink to the bottom of water in crude oil. The invention is to pour spherical foam 1 wrapped by carbon fiber 2 into a spherical structure, put the spherical foam into a customized spherical mould, pour a layer of carbon fiber ball outside the spherical foam to prepare a carbon fiber spherical body, and pour and wrap a layer of polyurethane 3 material isocyanate monomer and hydroxyl compound outside the carbon fiber spherical body to polymerize. The invention aims to solve the problem that a solid paraffin ball reflected by a client is high in density and difficult to salvage, and finds out in continuous exploration and exploration that how to change the density of the solid paraffin ball to solve the problem is how to change the density of the solid paraffin ball? Experiments show that only carbon fiber wrapped spherical foam is put into a customized mould, polyurethane is poured into the mould, a layer of polyurethane is wrapped on the periphery of the mould, and the effect is good. Therefore, the difficult problem that customers are difficult to salvage is solved, and the dredging efficiency is high and the collection is easy.
When the carbon fiber casting type polyurethane hollow paraffin removal ball is used, the carbon fiber casting type polyurethane hollow paraffin removal ball is placed in a petroleum conveying pipeline with a high temperature, due to the fact that the temperature of petroleum is high, the spherical foam 1 is subjected to cluster shrinkage at a high temperature, the size is greatly reduced, a certain amount of space is generated in the carbon fiber 2 sphere, buoyancy is generated, the carbon fiber 2 sphere is wrapped with cyanate, the sealing effect of the carbon fiber casting type polyurethane hollow paraffin removal ball is better, and the service life of the carbon fiber casting type polyurethane hollow paraffin removal ball.
