Abstract
The utility model relates to a high-temperature thermal couple anti-leak junction box of a gasification furnace, comprising a junction box shell. A junction box cover is arranged at one end of the junction box shell, a junction pipe is arranged at the other end of the junction box shell, a guide sleeve is arranged on the junction box shell, a junction post is arranged in the guide sleeve. The junction box shell is processed by 30 # steel, the junction box cover is processed by stainless steel, the junction post is processed by stainless steel, one end of the junction post is M6 internal thread which is convenient for pressing and welding thermal couple wires, the other end of the junction post is M8 external thread which is convenient for externally pressing and welding a compensation lead. A sealing pad has a main function of insulating the junction post from the junction box; besides, the sealing pad has another function of sealing. Processed by PPL polyphenyl, the sealing pad has a better property of temperature tolerance than that of Teflon. The junction box can be used after being completely assembled and passing an air tight pressure test. By utilizing the high-temperature thermal couple anti-leak junction box, the malfunction of synthesis gas leakage of a high-temperature thermal couple protective bushing is eliminated and the production safety is improved. The high-temperature thermal couple anti-leak junction box has advantages of strong safety, high reliability, convenient processing and production, long-term recycling use, temperature and pressure tolerance, and the like.
Description
Technical field
The utility model relates to a kind of terminal box, especially a kind of vapourizing furnace high temperature thermocouple anti-leak terminal box.
Background technology
The high temperature thermocouple of measuring temperature in the vapourizing furnace is as vapourizing furnace one of the main temperature element of grasping temperature that feeds intake of driving; because temperature is up to 1300 ℃ in the vapourizing furnace; furnace pressure〉2.7MPa; when vapourizing furnace normally moves; coal water slurry and oxygen blending ratio mixed firing and output synthetic gas; cause gasification stove internal wall refractory brick to wash away under the effect of coal slurry burning and furnace pressure, the protective casing of temperature-measuring heat couple is contained in advance and also is subjected to erosion in the refractory brick, cause synthetic gas by protective tube to external leakage.Since the gaseous tension height in the vapourizing furnace, the temperature height, and the design of existing temperature-measuring heat couple terminal box is unreasonable, terminal box is the cast aluminium material, the low anti-leak (see figure 1) of not considering of intensity.The generation synthetic gas leaks directly influence safety in production and damages patrolling and examining maintenance personnel's person.Have only blowing out to change, art breading is also very complicated, and influence is saved energy and reduce the cost and reached finishing of production task.
Summary of the invention
The utility model provides a kind of safe and reliable for overcoming above-mentioned the deficiencies in the prior art, is convenient to processing and fabricating, can reuse for a long time, not only the vapourizing furnace high temperature thermocouple anti-leak terminal box of heatproof but also carrying capacity.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of vapourizing furnace high temperature thermocouple anti-leak terminal box, comprise terminal block housings, terminal block housings one end is provided with connector cover, and the other end is provided with adapter, terminal block housings is provided with guide pin bushing, is provided with terminal stud in the guide pin bushing.
Described connector cover one end is standard hex, and the other end screws by screw thread, gasket seal and terminal block housings thread seal.
Described guide pin bushing is 120 degree angular bit holes and is vertically welded in the right cylinder of terminal block housings.
Be provided with gasket between described terminal stud and the guide pin bushing, on terminal block housings, the other end is provided with screw thread and is arranged in the terminal block housings end of terminal stud by nut, spacers.
The utility model terminal block housings is the processing of 30# steel, and periphery is 120 degree angular bit eyelet weldings and is connected to guide pin bushing.Connector cover is stainless steel processing, and an end Processing Criterion hexagonal is convenient to gasket seal and the terminal block housings screw thread screws sealing.Terminal stud adopts stainless steel processing, and an end is the M6 internal thread, is convenient to the crimping thermocouple wire, and an end is processed as the M8 outside screw and is convenient to outer crimping compensating lead wire.The gasket major function plays terminal stud and terminal box insulation, plays sealing function again, and with the processing of contraposition polyphenyl material, heatproof is better than tetrafluoroethylene.After all assembling finishes, should carry out airtight pressure testing and can use after qualified.
Through use the utility model, stopped high temperature thermocouple protective casing synthetic gas leakage failure, improved production security.The utlity model has safe and reliablely, be convenient to processing and fabricating, can reuse for a long time, not only advantage such as heatproof but also carrying capacity.
