Abstract
An electrical heating device for a high temperature distillation kettle comprises two heating pipes, wherein the two heating pipes are connected with cold end connecting electrodes to form a heating component; the two heating pipes are connected through connecting electrodes and mounted at the bottom of a reaction kettle, and are connected with high temperature resistant conducting wires; sleeves are nested outside the high temperature resistant conducting wires; and protective covers are mounted outside the heating pipes. The electrical heating device eliminates the potential safety hazards of the high temperature distillation kettle during operation, enables products to meet standard requirements and production target after being operated; the equipment has stale working conditions; the service life of each heating pipe is prolonged, and the heat efficiency is improved; the appliance part of the high temperature distillation kettle is lossless; and the maintenance cost of equipment is reduced greatly.
Description
Technical field
The utility model relates to a kind of heater, is specifically related to a kind of high temperature distillation still electric heater unit on the benzophenone ultra-violet absorber production line that is applied to.
Background technology
Distillation still is one of modal equipment in the chemical industry, also is that danger is bigger, and the equipment of leakage and fire explosion takes place easily.The stainless steel high temperature distillation still is the rough distilling period key equipment of benzophenone uv-absorber, and this equipment heating control section is divided into chuck oil immersed type electric heating tube, and (12 * 4KW) energising heating, thermometric instrument is automatic, manual to be controlled.Agitated reactor bottom electric heating tube cold junction length is too short, and temperature is higher, and it is aging that lead is prone to heating, and contact resistance becomes big during with the operation platform gradually; Lead is aging, carbonization is very fast, and the end of a thread is prone to blow, and the conduction oil seepage very easily causes naked light; And maintenance is frequent, and changing heating tube needs cold oil, drains the oil, when maintenance has a strong impact on workbench; The production chain interruption can only stop the line maintenance, causes the production run bottleneck.
Summary of the invention
The utility model provides a kind of long service life, safe and reliable high temperature distillation still electric heater unit.
The purpose of the utility model is achieved in that a kind of high temperature distillation still electric heater unit; Comprise heating tube, two heating tubes and cold junction connection electrode constitute a heating component, connect through connection electrode between two heating tubes; Heating tube is installed in the agitated reactor bottom; Heating tube is connected with high temperature resistant wire, and high temperature resistant wire is set with sleeve pipe outward, and the heating tube outside is equipped with protective cover.Described sleeve pipe is high temperature resistant tetrafluoro sleeve pipe.The cold junction connection electrode is provided with the lead-out wire stake, establishes trim ring in the line stake, is lead between trim ring and the pressure cap.The bottom cold junction length of heating tube is not less than 150mm.Add transition spool piece on the irony pile crown of heating tube electrode.Protective cover adopts the A3 steel to process.
The kind high temperature distillation still electric heater unit that the utility model provides has following beneficial effect:
1, strengthens the electrothermal tube electrode and draw the lead contact-making surface; Processing and fabricating A3 transition spool piece adopts the irony pile crown to draw to make full use of whole contact-making surfaces of former irony pile crown Φ 4*22, increases contact-making surface; Effectively reduce contact resistance, can prevent that lead produces power attenuation because of contact resistance and heating is aging;
2, original protective cover (PP material) is replaced by A3 material protective cover, increases the electric prospection facility, can eliminate electric leakage, leakage of oil hidden danger;
3, design customization 4KW electric heating tube again, lengthening bottom cold junction length effectively reduces heating tube exposed junction caloric value, can improve heat efficiency simultaneously, reduces anodizing, degradation trend speed;
4, change wire insulation into cover tetrafluoro insulation heatproof flame-retardant material, prevent that effectively lead from igniting.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the utility model heating tube joint design sketch map.
Fig. 3 is that the utility model heating line partly connects sketch map.
The specific embodiment
A kind of high temperature distillation still electric heater unit; Comprise that 1, two heating tube of heating tube 1 and cold junction connection electrode 2 constitute a heating component, connect through connection electrode 3 between two heating tubes 1; Heating tube 1 is installed in the agitated reactor bottom; Heating tube 1 is connected with high temperature resistant wire 4, is set with sleeve pipe 5 outside the high temperature resistant wire 4, and heating tube 1 outside is equipped with protective cover 6.Sleeve pipe 5 is high temperature resistant tetrafluoro sleeve pipe.Cold junction connection electrode 2 is provided with lead-out wire stake 7, establishes trim ring 8 in the line stake 7, is lead 10 between trim ring 8 and the pressure cap 9.Lead-out wire stake 7 is an irony, and trim ring 8 adopts brass to process with pressure cap 9, and lead 10 is a sub-thread red copper lead, can reduce the oxidizing process of generating heat and causing.The bottom cold junction length of heating tube 1 is not less than 150mm.Add transition spool piece 11 on the irony pile crown of heating tube electrode.Protective cover 6 adopts the A3 steel to process.
During the utility model line, circuit is drawn through explosion-proof wiring terminal box 12, is connected with the wiring pile of heating tube through 13 backs of crane span structure at the bottom of the still, supplies power to heating tube.
