Abstract
The utility model discloses a safe and energy-saving electric air heating device which comprises an electric heating box, a fan, a wind return pipe, a thermal fuse, a working circuit and an outer box body. The electric heating box comprises a liner, an inner box body, an electric heating element, a liner cover, an inner box cover, a protection hood, a built-in spark partition screen and heat insulation materials. When the safe and energy-saving electric air heating device works, the electric heating box is energized to heat, air is pumped out of an oasthouse by the fan, pressed and sent into the electric heating box to be heated. The heated air is sent into the oasthouse. The above process is repeatedly constantly, so that the oasthouse is heated. When a temperature of the oasthouse reaches the required level, an additional temperature control device can keep the temperature in the oasthouse steady. A moisture pump pumps moisture evaporating from materials. The spark partition screen eliminates possible sparks generated during heating. The thermal fuse can cut off the working circuit of the electric heating element in case of the temperature is out of control in the electric heating box. The safe and energy-saving electric air heating device is provided with circulation heating and heat partition measures so as to save energy. The spark eliminating device, the thermal fuse and the like are applied to keep safe.
Description
[technical field]
The present invention relates to the heating plant in a kind of drying equipment, especially a kind of safety energy-saving electric hot air apparatus.
[background technology]
Main five classes of heating plant in the traditional drying equipment: a class is coal fired boiler; Another kind of is the boiler of combustion gas or fuel oil; Also having a class is exactly the air-heater of combustion gas or fuel oil; The air heat energy pump and the electric hot-air device that occur in the recent period besides; In addition to the above, in some industries backward in technique, still have the soil barn processed of a large amount of burning faggots continuing use.Though said apparatus can both use, all have serious deficiency: the coal fired boiler pollution is heavy, temperature is wayward; The boiler of combustion gas or fuel oil or air-heater equipment investment are large, and cost of use is high; The impact of air heat energy pump climate is large, microthermal climate, and heating effect subtracts greatly, can not satisfy the requirement of work; The electric hot-air device technique is also not overripened; The barn of burning faggot can consume a large amount of faggots, thereby can cause the minimizing of vegetation and the destruction of ecological environment.
If be used for the drying equipment of inflammable and explosive industry (fireworks, the people are quick-fried, war production etc.), except the basic demand that possesses general drying equipment, must also to satisfy safe and reliable requirement, never allow to occur accident on fire and blast.
At present, both can use in general industry, can use in inflammable and explosive high risk industries again, particularly not only safety but also energy-conservation heat energy feeding mechanism also do not have.
[summary of the invention]
The objective of the invention is to provide a kind of not only safety but also energy-conservation electric hot-air device, it can not only be used in the general industry, can be used on again in the inflammable and explosive high risk industries.
A kind of safety energy-saving electric hot air apparatus of the present invention is by outer case, electrocaloric effect, blower fan, backwind tube, Temperature protection, electrocaloric effect work lead-out wire, blower fan work electric wire, Temperature protection lead-out wire and patchcord installation composition.And the air outlet of blower fan is connected with electrocaloric effect, and air inlet is connected with backwind tube; Temperature protection is contained between blower fan and the electrocaloric effect; Electrocaloric effect work lead-out wire, blower fan work electric wire and Temperature protection lead-out wire are connected with the patchcord device; Above parts all are fixed on the outer case.
Described electrocaloric effect cuts off screen by inner bag, internal box, heating, inner bladder cover, interior case lid, protective cover, built-in spark and heat-barrier material forms, and heating connects with inner bladder cover and interior case lid; Inner bladder cover covers inner bag, interior case lid covers internal box; Inner bag is contained in the internal box, and built-in spark cuts off screen and is contained in internal bladder cavity; Between inner bag and internal box, install heat-barrier material additional; Electrocaloric effect work lead-out wire is connected with heating, and protective cover covers the terminals of heating.Described built-in spark cuts off screen and is combined by multiple layer metal filter screen and fixed frame, and the multiple layer metal filter screen is overlapping to be fixed together afterwards with fixed frame, then is installed in internal bladder cavity.
Need to prove that also the present invention is a kind of safety energy-saving electric hot air apparatus, the complete drying equipment of a cover also should comprise air-supply and air return pipeline, drying shed, temperature control device, automatic humidity-discharging device, automatic operation control device etc.If be used for inflammable and explosive industry, also need in return air, add the devices such as dust-filtering, overheat protector and far distance controlled, only in this way, the science of guarantee drying equipment, efficient, safe and reliable operation.
The operation principle of this device is: the heating heating power, blower fan work deflates in drying room by return air duct, through being sent to heating in the electrocaloric effect after dust filtering device filtration and the supercharging, air after the heating passes spark and cuts off screen, then enter drying room through ajutage, temperature in the drying room is risen, above process constantly repeats, temperature in the drying room constantly rises, rise to the temperature that sets when temperature after, temperature control device sends signal, make heating stop heating power, drop in temperature in the drying room, when drop in temperature after the temperature that sets, temperature control device can send the signal that makes heating work again, heating again can heating power, temperature in the drying room can rise again, so moves in circles, and makes the temperature in the drying room keep certain.In addition, in the process of drying room work, automatically humidity-discharging device can be discharged moisture in the drying room automatically according to the hydrofuge mode that sets, and allows material flash baking in the drying room.
Guarantee safe technical measures, have two in device of the present invention: one is that spark cuts off screen, and another is Temperature protection; The principle that spark cuts off screen is when contingency has trickle spark to produce in the electrocaloric effect, to contact with the collision that spark cuts off the multiple layer metal filter screen in the screen by spark, and spark is cooled off by heat absorption rapidly and eliminates; The principle of Temperature protection is that Temperature protection is by quick-break when blower fan stall or other reason cause temperature control in the electrocaloric effect too high, and the control circuit of heating is cut off, and the heating outage quits work.Add the application of the safety measures such as filtration, far distance controlled, remote heat supply of regulation and control, the return air dust of temperature in the drying room, can guarantee that the safety of drying equipment is perfectly safe.
Conservation measures mainly contains two: one is that the interior air of drying room is circulating-heating, and cold air advances not go, and hot gas can not run off; The 2nd, installed heat-barrier material additional in the electric hot-air device, heat can not scatter and disappear.
Electric hot-air device of the present invention is compared with traditional heating plant, and it does not pollute, equipment investment is little, cost of use is low, temperature is controlled well, simple to operate, reliable operation, secure safely.
