Abstract
The utility model relates to a novel heating thermal sleeve for a wellhead conveying apparatus. The novel heating thermal sleeve is characterized by carbon fiber heating wires, a waterproof layer, an intermediate thermal insulation layer, an external waterproof fireproof anticorrosion layer, fixed connecting buckles, and an explosion-proof device for the heating wires and metal leads. With the adoption of the novel heating thermal sleeve, since the outside of the wellhead conveying apparatus is provided with the heating and thermal insulation apparatus, the liquid inside the apparatus can flow smoothly in a low-temperature environment. The novel heating thermal sleeve is rapid and uniform in heating, energy-saving, fireproof, waterproof, anti-corrosion and anti-arcing, can be installed and maintained in a detachable manner, and is suitable for the heating and thermal insulation of wellhead conveying apparatus in difference shapes.
Description
Technical field
The utility model relates to a kind of heating and thermal insulation 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 coated 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 conventional, electric-resistance silk is wound around, quantity of heat production is low, heating rate is slow, cannot guarantee the mobile smooth and easy of mud, and 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, cannot be guaranteed, and life-span and recycling rate of waterused are lower.Outer field plastic film and chemical fibre not simple random coated, cannot guarantee stable thermal loss.Though final heating source has added the safety measures such as explosion-proof, for the too much plastic film in working site and chemical fibre insulation material, cannot guarantee the job security of the aspect such as fire-resistant, to use, brought significant limitation.
Summary of the invention
Technical problem to be solved in the utility model 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 heating and thermal insulation cover of safety in production.
The defect or the deficiency that for above-mentioned technology, exist, the utility model aims to provide a kind of well head conveying device Novel heating muff, the technical scheme adopting is: in pipeline, fuel tank outside, be provided with muff, on muff edge, be provided with and be fixedly connected with button, described junction button can be thread gluing, slide fastener, button, frenulum, clasp, cingulum, can be also the combination between them.In muff inside, press close to pipeline one side 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 utility model adopts following technical scheme:
A 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 heating and thermal insulation body that can be coated 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 muff integral plaster 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 utility model 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, have good adaptability, can alternating bending 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, is all better than the coated mode of original simple electric blanket heating and insulation material in structure and performance, for environmental safety and the tidiness of working site, all improves a lot.
