Technical field
The present invention relates to technical field of mechanical equipment, specifically honeycomb type is for core.
Background technology
Heater is in electronics, food, pharmacy, printing, packaging, cleaning, heat treatment, and every profession and trade has application prospect very widely.Fan heater is that air-heater simplifies product, is the first-selected product of modern industry thermal source upgrading, is the optimal heat wind regime configuration of the automated machines such as hot blast furnace conveyor, drying oven, baking oven, packaging machine.
Fan heater is made up of forced draft fan, heater, control circuit three parts, operation principle is as follows: after energising, air blast blow air in heater, air is made evenly to pass through from spiral helicine heating wire medial and lateral, the heat produced after heating wire energising carries out heat exchange with the cold air passed through, thus the wind-warm syndrome of air outlet is raised.The leaving air temp detected is fed back to temperature controller by the thermocouple at air outlet place in time, and instrument according to the actual temperature of the temperature monitoring of the setting work of, and will transmit back solid-state relay and then whether control heater works for information about.According to wind tunnel effect appropriate design, air-out is evenly passed through from spiral heating wire inside/outside side, and rate of heat exchange is high, and air quantity, air loss are few;
Heating wire in fan heater is mostly adopt 2080 nickel filament coilings, and air-out is evenly passed through, and does not produce waste gas and special odor, meets environmental protection.Also be provided with overtemperature protection system, band power-off protection, fully ensures device security simultaneously, annual within 365th, can not stop operation.Under normal circumstances, the maximum operation (service) temperature of fan heater is that scope is at 350 DEG C ~ 650 DEG C.The K type thermocouple be equipped with by air outlet place, is controlled by PID/SSR, and the accurate control of temperature can reach 1 DEG C, and feedback is fast, durable.And regulate motor speed to regulate air quantity by frequency converter can be joined, can accurately grasp temperature and air quantity.
Due in fan heater use procedure, the useful life of heater is the shortest, the situation that heating wire fuses can be first there is under normal circumstances due to the aging of heating wire, now, or replace heat generating core, or directly change fan heater, also do not have a kind of structure simple, easily manufactured at present, the efficiency of heating surface is high, and unit ventilation quantity is large, and it is special for core that replacing simply adds warm-air pipe.
Summary of the invention
The present invention is just for above technical problem, and provide a kind of structure simple, easily manufactured, the efficiency of heating surface is high, and unit ventilation quantity is large, and it is special for core that replacing simply adds warm-air pipe.
The present invention realizes mainly through following technical scheme.
Honeycomb type is for core, comprise fixed leg, insulator cap, core body, tail-hood, hold-down nut, conductive pole, heater strip, head end, tail end, it is characterized in that insulator cap, core body, tail-hood is that pottery is made, be successively set on fixed leg, fixed leg head end expands, tail-hood arranges hold-down nut, hold-down nut is by compressing tail-hood by insulator cap, core body, tail-hood is fixed on fixed leg, tail-hood is matrix near core body one middle side part, core body is provided with multiple through hole, through hole is honeycombed, run through core body end to end, through hole is honeycombed, the distance of the most near side (ns) of arbitrary neighborhood two through holes is all equal, insulator cap is provided with conductive pole, heater strip is first from spirally-wound, again successively through the multiple through holes on core body, heater strip two ends are respectively head end, tail end, head end, tail end gives prominence to core body, and be connected with the conductive pole on insulator cap.Be threaded connection between hold-down nut and fixed leg.Fixed leg, hold-down nut are made up of refractory metal.Through hole on core body divides three layers of arrangement, and number of through-holes is respectively 1,6,12.
The fixed leg that the present invention is made by refractory metal and the insulator cap that pottery is made by hold-down nut successively, core body, tail-hood press together, and heater strip is wound on core body that pottery makes, heater strip can be fixed well, heater strip is first from spirally-wound, add the heater strip hardness in manufacturing process, be conducive to processing, turn increase unit volume heater strip length, increase power.And tail-hood is arranged to matrix in the middle of core body side, can not heater strip be urged to when being fixed by hold-down nut, causes the accident of heater strip to rupture, extending useful life.
Structure of the present invention is simple, and heating wire is ensconced in ceramic cavity with suspension type, and hot blast can pass through from heating wire both sides equably, and air quantity is large, and windage is few, and heating wire temperature is lower.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is structural representation of the present invention, and Fig. 2 is schematic cross-section of the present invention, wherein:
1-fixed leg, 2-insulator cap, 3-core body, 4-tail-hood, 5-hold-down nut, 6-conductive pole, 7-heater strip, 71-head end, 72-tail end, "○" is that heater strip passes cross section, and "+" penetrates cross section for heater strip.
