The front view of the electromagnetic heater that Fig. 2 relates to for the utility model;
Fig. 3 is the A-A cutaway view of Fig. 2.
Be labeled as among the figure: hot-blast stove 1, cold wind input port 11, hot blast delivery outlet 12, electromagnetic heater 2, electromagnetic induction coil 21, heating plate 22, heat insulation foam 23, fin 24, blower fan 3, hot blast efferent duct 4, the machine 5 that deblocks, dewaterer cylinder 6.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3 be the dewaterer that is used for the tealeaves dehydration procedure that a kind of energy loss is low, the efficiency of heating surface is high that the utility model provides, described dewaterer comprises dewaterer cylinder 6, heater and blower fan 3, also comprises the hot-blast stove 1 that contains cavity; Hot-blast stove 1 cavity is provided with cold wind input port 11 and hot blast delivery outlet 12; The output of blower fan 3 is communicated with the cold wind input port 11 of hot-blast stove 1 cavity; The output of hot-blast stove 1 cavity is communicated with dewaterer cylinder 6; Heater is an electromagnetic heater 2, is installed in hot-blast stove 1 cavity; Described electromagnetic heater 2 comprises electromagnetic induction coil 21 and heating plate 22; Heating plate 22 is positioned at the outside of electromagnetic induction coil 21.Like this, on cavity, have cold wind input port 11 by being provided with one, the hot-blast stove 1 of hot blast delivery outlet 12, and the hot blast delivery outlet 12 of this hot-blast stove 1 cavity is communicated with dewaterer cylinder 6, then the resistance furnace heater is changed into electromagnetic heater 2 and be installed in hot-blast stove 1 cavity, directly in hot-blast stove 1 cavity, provide heat, in hot-blast stove 1 cavity, import cold wind by blower fan 3 again, through being transported in the dewaterer cylinder 6 after electromagnetic heater 2 heating, the tealeaves of sending in the dewaterer cylinder 6 after being dismissed by the machine of deblocking 5 is carried out processed, in this process, heat produces the back by electromagnetic heater 2 and in hot-blast stove 1 cavity the cold wind by blower fan 3 inputs is heated, and then hot blast is transported in the dewaterer cylinder 6, the loss of heat in conductive process and the electric energy loss of heating self have been reduced, thereby reduced the energy loss when generating hot blast greatly, in the cavity of a sealing, cold air is heated simultaneously, also can effectively raise the efficiency of heating surface.We know, electromagnetic induction heating is to produce magnetic field by feed alternating current in electromagnetic induction coil 21, the heating plate 22 self that is positioned at magnetic field produces that eddy current generates heat, heating plate 22 does not need other heaters to heat like this, so just there be not the thermal losses of heat in conductive process, there is not simultaneously the electric energy loss of heating self yet, therefore energy savings significantly, simultaneously, electromagnetic induction coil 21 does not generate heat yet, can reduce the loss of electric energy equally, but when heating plate 22 produces eddy-current heating, can exert an influence electromagnetic induction coil 21, in order to prolong the long service life of electromagnetic induction coil 21, guarantee the reliable and stable of its work, between heating plate 22 and electromagnetic induction coil 21, be provided with heat insulation foam 23, prevent that 22 pairs of electromagnetic induction coils 21 of heating plate of high temperature from causing damage.
The purpose that electric hot plate 22 is heated, be in order to heat by the cold air in blower fan 3 input hot-blast stoves 1 cavity, so just must be fast as far as possible make heat diffusion on the heating plate 22 in ambient air, in order to accelerate this diffusion process, in heating plate 22 outsides fin 24 is installed also, improve firing rate to enlarge area of dissipation, thereby further improved the thermal efficiency of heater.
When the electromagnetic heater in the above-mentioned embodiment 2 has only one, its efficiency of heating surface still is limited, for the further efficiency of heating surface that improves hot-blast stove 1,2 at least two of the electromagnetic heaters that in hot-blast stove 1 cavity, is provided with, staggered is installed on the two side relative in hot-blast stove 1 cavity; Staggered many electromagnetic heaters of installing 2 constitute the cold wind heat tunnel with hot-blast stove 1 cavity inner wall, and cold wind input port 11 and hot blast delivery outlet 12 lay respectively at the two ends of cold wind heat tunnel.After the cold wind that is provided by blower fan 3 enters hot-blast stove 1, can repeatedly heat like this, reach the purpose of effective raising efficiency of heating surface along the cold wind heat tunnel.
For the structure that makes whole heater try one's best simple, manufacturing cost is cheap as much as possible, be communicated with by a hot blast efferent duct 4 between hot blast delivery outlet 12 in the above-described embodiment and the dewaterer cylinder 6.So both can make the structure of hot-blast stove 1 the simplest, hot blast directly can have been imported in the dewaterer cylinder 6 again, reduce the loss of heat in the course of conveying, further reduce energy loss.
In the above-mentioned embodiment, in order to make being distributed on the tealeaves by the hot blast energy homogeneous and controllable in the hot blast efferent duct 4 input dewaterer cylinders 6, make dehydration procedure dewatering as far as possible evenly to tealeaves, the end that hot blast efferent duct 4 is communicated with dewaterer cylinder 6 stretches in the dewaterer cylinder 6, is provided with a plurality of exhaust vents 41 on the hot blast efferent duct 4 in this stretches into dewaterer cylinder 6 vertically.So just, can make hot blast carry billowing 6 each interior place of dewaterer uniformly, it is bigger can not go out the front and back end temperature difference, and uneven phenomenon dewaters.
In sum, replace original resistance wire heating or FAR INFRARED HEATING mode by the heater that mainly constitutes by hot-blast stove 1 that contains cavity and electromagnetic heater 2, be to control the temperature of hot blast and speed by changing the electric current in the electromagnetic induction coil 21 or changing intake in the blower fan 3, the rotating speed of hot blast temperature, blast, air quantity and dewaterer cylinder 6 all can be according to tealeaves situation and arts demand adjustment like this, can effectively improve the tealeaves dehydrating effect that deblocks, guarantee tea leaf quality.
