Description
Technical field
The present invention relates to a kind of heater, particularly a kind of take conduction oil as the tubular heater of medium, and this heater is for the production of the sizing material of epoxy radicals pultrusion plug and alkali-free glass fibre heating.
Background technology
Epoxy radicals pultrusion plug is a kind of composite insulating material, and this material, apart from outside excellent insulating properties, also has intensity high, heat-resisting, cold-resistant, and the characteristics such as mildew-resistant, protection against the tide, shock resistance, have a wide range of applications in electric device.Along with the development of power industry and improving constantly of line voltage grade, propose requirements at the higher level to supporting epoxy radicals pultrusion plug quality index, the specification of market demand is also increasing.Epoxy radicals drawing and extruding bar is formulated by raw materials such as epoxy resin, alkali-free glass fibre, catalyst, and the sizing material first mixture become during production and alkali-free glass fibre traction are in mould, and then it is shaping to be heated to 160 DEG C ~ 200 DEG C heat cures.The epoxy radicals pultrusion plug of the following specification of φ 130mm is little because of volume, can accomplish overall heating under prior art conditions and synchronously solidify.And the epoxy radicals pultrusion plug being greater than φ 130mm because of volume relatively large, be difficult to accomplish that internal and external temperature is consistent under the heating condition that existing equipment is supporting, internal-external temperature difference must cause solidification asynchronous, and the internal stress generated thus easily causes crackle and causes product rejection.So the commodity epoxy radicals pultrusion plug circulated in current market only has the following specification of φ 130mm, does not have the above specification of φ 130mm.Radiothermics was once used for the production of large gauge epoxy pultrusion plug by some manufacturers of the industry, although this kind of heating technique is effective.But radiothermics is applied in when epoxy radicals pultrusion plug is produced exists two large problems.Maximum problem is Contamination of Electromagnetic Wave, and both to have endangered worker healthy for the electromagnetic wave that heating process produces, and also has severe jamming to the communication of periphery, instrument, electronic equipment.Another problem is that corollary equipment is expensive, and heating energy consumption is large, the inevitable larger production production cost of high energy consumption.Just due to the problems referred to above objective reality, radiothermics be not suitable for the production of epoxy radicals pultrusion plug.
Summary of the invention
The present invention can only produce the deficiency of the following specification of φ 130mm mainly for the heater that existing extruding equipment is supporting, proposes a kind of structure simple, easily supporting, heats convenient, even, reliable Hot oil type tubular heater.This heater assigns in sizing material intake, solidify to die cavity through traction after the sizing material flow through along heater inside and outside wall and alkali-free glass fibre are heated, this heating arrangement realizes product ectonexine and synchronously solidifies under same temperature condition, and the epoxy radicals pultrusion plug being conducive to doing φ 150mm ~ φ 200mm is produced.
The present invention is achieved through the following technical solutions technical goal.
Hot oil type tubular heater, it comprises shell, pipe joint, ingress pipe, return duct, thermal medium and sensor.Improvements are: described shell is jacket pipe structure, built-in axially in pipe placed in the middle, outer tube wall with the coaxial fit of interior pipe and two ends be mutually tightly connected.Outer tube wall is made up of truncated cone and cylinder, within one end pipe for starting point be truncated cone small end, the cylindrical bundle sections of the other end is provided with screw thread and coordinates with pipe joint and form location and installation, and in the bundle segment ring of shell outer tube wall, pipe is equidistantly alternately tightly connected ingress pipe and return duct.Described thermal medium is conduction oil, and ingress pipe and return duct composition thermal medium circulate passage, coaxial placement sensor between any ingress pipe and adjacent reflow pipe.
In said structure, the interior pipe of shell is internal diameter φ 10mm ~ φ 50mm round tube, and the tapering of outer tube wall truncated cone is 1: 4 ~ 1: 6.Be arranged on the ingress pipe in shell and return duct totally 2 ~ 16, the internal diameter of ingress pipe and return duct is equal, and ingress pipe is than backflow pipe range, and the end of ingress pipe is positioned at the truncated cone section inner chamber place of shell, and the end of return duct is positioned at shell bundle sections inner chamber place.Sensor is the temperature sensor of 0 DEG C ~ 300 DEG C.
The present invention compared with prior art, has following good effect:
1, tubular heater structure is simple, easy to manufacture, installation site is reliable;
2, among the tubular heater sizing material that is in configuration and alkali-free glass fibre, heating is quick, evenly, energy consumption of unit product is only 1/20 ~ 1/30 of prior art, and production cost is low, good in economic efficiency;
3, the sizing material introducing die cavity is heated under identical temperature conditions with alkali-free glass fibre, and heating-up temperature is consistent, heat cure steady quality, and the epoxy radicals pultrusion plug being particularly suitable for specification between φ 150mm ~ φ 200mm is produced;
4, do not produce problem of environmental pollution in heating process, security is good, and social benefit is remarkable.
