Description

A kind of device that prevents the platinum channel distortion

Technical field

The utility model relates to a kind of modifying device of producing the used platinum channel of glass, particularly a kind of device that prevents the platinum channel distortion.

Background technology

The thawing clarification of glass is a very complicated process, and it has comprised that series of physical changes and chemical reaction.These variations are to make the various raw materials of fused become chemically combined uniform glass liquid.Also can produce many defectives in the glass thaw process, as bubble, calculus, striped etc.In order the gas in the vitreum to be got rid of as much as possible totally, clarifying temp is also in continuous rising, after reaching certain ultimate temperature, use common refractory can not satisfy the requirement of production to glass quality, bring into use platinum to do the process that pipeline is finished glass clarifying and homogenizing, platinum can bear the high temperature up to 1700 ℃ and glass metal do not caused obvious pollution under the normal circumstances, can not cause the generation of glass defect, especially platinum rhodium, withstand temp is higher.Yet platinum meeting deliquescing under the high temperature, and then in various external environments constantly change, produce creep, slowly distortion has finally caused subsiding of platinum channel, and can't continue to produce.

Method commonly used is to increase laterally to strengthen gusset in platinum channel, and to increase the anchorage force of platinum channel, temperature is the highest in the platinum channel, strengthens gusset under so high temperature, still can slowly be out of shape; The height of strong gusset is subjected to the restriction of glass liquid level, simultaneously because the platinum fancy price has increased manufacturing cost greatly.

Conventional structure mounting means is the outside direct flame-proof thermal insulation material that is of platinum, and flame-proof thermal insulation material is firm body, can not fit fully with the platinum channel outside, can more or less stay the slit.Because the fire resistant heat preserving material in the platinum outside is a shaping material,, can shrinks by generation trace in various degree, thereby between platinum channel and flame-proof thermal insulation material, stayed small slit behind temperature-rise period.At high temperature in the operational process, the platinum deliquescing can produce along the outside thrust of platinum channel flame-proof thermal insulation material under the pressure effect of platinum and glass, might make outside refractory brick produce small variation, and platinum horizontal direction both sides are expanded outwardly.After outwards moved the platinum both sides, the platinum top had lost the support of domes, sank owing to deliquescing under the effect of gravity thereupon, had finally caused caving in of platinum channel.

Summary of the invention

In order to solve in the prior art, flame-proof thermal insulation material and platinum channel can not well be fitted, in the hot operation process, platinum channel caves in easily, influence the problem in work-ing life, the technical scheme of employing is: a kind of device that prevents platinum channel distortion is applicable to the high temperature section of platinum channel, comprise the thermal insulation layer that lagging material is formed in the structure, include in the structure of device: the outer horizontal direction bending resistance enhancement Layer of thermal insulation layer, thermal insulation layer that is arranged on the platinum channel periphery.

The beneficial effects of the utility model are: the external pressure that is arranged so that of thermal insulation layer can evenly be delivered to each position of platinum channel, can isolate simultaneously direct contact the between platinum channel and the refractory materials, prevents the erosion of refractory materials to platinum.Being provided with of bending resistance enhancement Layer increased to the platinum channel level to holding force, make platinum channel form similar turtle shell or arch force structure, improved and be subjected to force intensity, thereby reached the effect that at high temperature prevents the platinum channel distortion.But the steel clamp region of independent regulation is set, provides holding force, can adjust applied pressure on the arch springing as required by steel construction.By the setting of above device, can keep to the platinum channel level to pressure, platinum channel arch force structure kept, reduced the top and sunk and the possibility of distortion.

The utility model is simple in structure, and is practical, and cost is low, effectively stoped platinum channel at high temperature to be out of shape, and prolonged the work-ing life of platinum channel.
