Abstract
The invention relates to a novel heating heat preserving sleeve of a well mouth conveying device. The novel heating heat preserving sleeve is characterized by comprising carbon fiber heating wires, a waterproof layer, a middle heat preserving layer, an outer waterproof, fireproof and anti-corrosion layer, a fixed connecting buckle and an anti-explosion device of the heating wires and metal guide wires. By the adoption of the technical scheme of the novel heating heat preserving sleeve, due to the fact that a heating device and a heat preserving device are arranged outside the well mouth conveying device, smooth flowing of liquid inside the device is guaranteed in a low-temperature environment. The novel heating heat preserving sleeve of the well mouth conveying device has the advantages of being quick in heating speed, capable of heating evenly and saving energy sources, fireproof, waterproof, anti-corrosion, anti-arcing, capable of being installed and maintained in a detachable mode, and suitable for heating and heat preserving of well mouth conveying devices different in shape.
Description
Technical field
The present invention relates to a kind of heat tracing cover of well head conveying device Novel heating muff, the especially pipeline of oil field shaft mouth conveying device, fuel tank.
Background technology
In view of north of china in winter oil field outside work temperature is lower, in drilling well-head conveying device pipeline, mud is easy to freeze at low temperatures, causes the not smooth problem of circulation.In order to guarantee the fluency of mud flow, the coating mode of the simple electric blanket heating of existing Oilfield using and common insulation material is simple, is easy to realize; But, the heating source that the method provides is the electric blanket that the conventional, electric-resistance silk is wound around, quantity of heat production is low, heating rate is slow, can't guarantee the mobile smooth and easy of mud, and the single sheet electric blanket, resistance wire intensity in it is low, bending property is poor, for the globality of heating technique, fluency, maintainability in the future, can't be guaranteed, and life-span and recycling rate of waterused are lower.Outer field plastic film and chemical fibre not simple random coating, can't guarantee stable thermal loss.Though final heating source has added the safety measures such as explosion-proof, for working site, too much plastic film and chemical fibre insulation material can't guarantee the job security of the aspect such as fire-resistant, to use, have brought significant limitation.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of for complicated pipe-line, fuel tank, do not destroy its globality, and use that a kind of heating efficiency is high, high insulating effect, and easy for installation, simple, maintain easily, explosion-proof performance is good, realizes the heat tracing cover of safety in production.
The defect or the deficiency that for above-mentioned technology, exist, the present invention aims to provide a kind of well head conveying device Novel heating muff, the technical scheme adopted is: in pipeline, fuel tank outside, be provided with muff, be provided with and be fixedly connected with button on the muff edge, described junction button can be thread gluing, slide fastener, button, frenulum, clasp, cingulum, can be also the combination between them.Press close to pipeline one side in muff inside and be provided with carbon fiber heating wire.The junction of carbon fiber heating wire and plain conductor all adopts explosion-protection equipment.
For achieving the above object, the present invention adopts following technical scheme:
A kind of well head conveying device Novel heating muff, the direct current by safety or exchange 36 volts of power supplys electric power is provided.Its inside is by the heat tracing body that can coat the well head conveying device that comprises carbon fiber heating wire and muff and form; the fillet of muff is provided with and is fixedly connected with button, and the junction of carbon fiber heating wire and plain conductor adopts explosion-protection equipment to carry out safeguard protection.
Muff consists of skin, heat-insulation layer and internal layer.Skin consists of high temperature resistant, oil resistant, waterproof, waterproof, fire-retardant, etch-proof material, and heat-insulation layer consists of resistant to elevated temperatures Polyester Fibers, and internal layer consists of high temperature resistant, waterproof, material fire-retardant, antistatic.The one side that the muff integral plaster the well head conveying device is provided with carbon fiber heating wire and insulating barrier.
The junction of carbon fiber heating wire and plain conductor adopts explosion-protection equipment to consist of epoxy resin and heat-shrink tube.
The advantage that the present invention compared with prior art had is: (1) consumes energy low, the rate of heat addition is large, electric heating conversion efficiency improves 30% than the heating of metallic resistance silk, electrothermal efficiency approximately 100%, be mud medium in pipeline stable heat is provided, also can guarantee that inner mud is not easy to rapid cooling under extraneous low ambient temperature.(2) heating cable heating cable long service life, intensity are high, have good decay resistance, for crooked complicated pipe-line, good adaptability is arranged, but alternating bending are not fragile.(3) the not starting the arc of live wire, the generation of effectively stopping fire; The blank area of all cables is all taked heat-shrink tube and epoxy resin dual-seal explosion-protection equipment; Outer muff adopts fire-proof and damp-proof double-layer heat insulation material, all is better than the coating mode of original simple electric blanket heating and insulation material on structure and performance, for environmental safety and the tidiness of working site, all improves a lot.
