Heated base is in the market by screw, to be assembled into one by heat-generating disc, iron pan, iron plate, nylon ring, face-piece and base.Face-piece and bottom are made by polypropylene.The gap that has 4-6 millimeter between nylon ring and face-piece.Due to face-piece and bottom, by polypropylene, made, cannot bear heavier load and impulsive force, intensity is not high.Between heat-generating disc and base, have very large space, thermal loss is larger simultaneously.And serviceability temperature is restricted.
Utility model content
Heater at the bottom of the purpose of this utility model is to provide a kind of barrel, adopts the mineral insulation heating cable of metallic sheath as heater element, and serviceability temperature is high, mechanical strength is large, and heat exchange efficiency is good, has solved the not high and larger problem of thermal loss of product strength.Meanwhile, in order to guarantee reliably to use in high temperature occasion, power supply leading-in end is not generated heat relatively, adopt the mode of cold and hot transition.
In order to achieve the above object, the utility model adopts following technical scheme: heater at the bottom of a kind of barrel, comprise heating plate, heater base, thermal insulation layer and plug, between heating plate and heater base, with bolt, be connected, the heater element of heating plate is the mineral insulation heating cable of metallic sheath, adopts mineral insulation heating cable as the heating plate of heater, to have that heating-up temperature is high, mechanical strength good, heat exchange is abundant, long service life; The main body of described heating plate and heater base is metal material, between heating plate and heater base, be filled with thermal insulation layer in the cavity of heater base, the conductive coefficient of the heat-barrier material that thermal insulation layer adopts is extremely low, heat-proof quality is 3-8 times of traditional material, the most of upwards conduction of heat, simultaneously high temperature resistant, long service life, and there is good mechanical performance.
As further preferred, described heater element is evenly arranged on heating plate, and is cast as one with heating plate, and heat-transfer effect is good, and heating evenly.
As further preferably, described mineral insulation heating cable be adopt nichrome core, constantan etc. as conductor layer, high-purity magnesium oxide mineral material as insulator layer, stainless steel a kind of cable as sheath.It can meet the needs of hot conditions and large heating power.There is good mechanical strength, corrosion-resistant, high temperature resistant, long service life, heat exchange efficiency high.
As further preferably, between heater element and power supply lead wire, introduce the mineral insulated cable of cold junction stainless steel sheath, cold junction stainless steel mineral insulated cable itself does not generate heat, but high temperature resistant, mechanical strength is high.Guaranteed that power supply leading-in end temperature is lower, safety and reliability.
As further preferably, two temperature elements are housed on described heater base, can carry out well temperature control, safety and reliability.
As further preferred, described heating disks in pyrolysis plant designs according to the bottom size of Raw material pail, surperficial dimpling.
The beneficial effects of the utility model are: (1) heating plate adopts stainless steel mineral insulation heating cable as heater element, heating evenly, surface loading is little, long service life, and it has solved the drawbacks such as the long-standing carbon distribution of conventional tube electric heater, booster, disconnected core, life-span be short.
(2) adopt the mode of cold and hot transition.Between heater element cable and power supply lead wire, introduce the mineral insulated cable of cold junction stainless steel sheath, cold junction stainless steel mineral insulated cable itself does not generate heat, but high temperature resistant, mechanical strength is high.Guaranteed that power supply leading-in end temperature is lower, connected reliably again heating end.
(3) size of the heating surface of heating plate at the bottom of according to bucket designs, surperficial dimpling, and with Raw material pail no-float, heat transfer efficiency is high.
(4) between heating plate and heater base, have heat-insulating heat-preserving material, good heat-insulation effect, upwards conduction is to Raw material pail to guarantee heat, and thermal loss is less.
(5) be furnished with two temperature elements, safety and reliability.
(6) heater is removable, convenient maintenance.
