The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Extremely shown in Figure 4 like Fig. 1; The tea drier of the utility model comprises frame 1 and is arranged on the baking oven 2 that has air intake vent and air outlet on the frame 1, connects the blast heater 4 with air outlet and air intake vent at the air intake vent place of baking oven 2; Air intake vent place at blast heater 4 is provided with blower fan 7; The air outlet of blast heater 4 communicates with the air intake vent of baking oven 2, in blast heater 4, is provided with heater, is provided with at the air outlet place of baking oven 2 to have inlet and the heat exchanging chamber 3 that exports; Be provided with heat exchanger tube 5 in the heat exchanging chamber 3, the outlet of heat exchanging chamber 3 communicates through the inlet of pipeline with blower fan 7.During work; Cold air at first gets into heat exchanging chamber 3 under blower fan 7 effects; The hot-air of in heat exchanging chamber 3, discharging with baking oven 2 air outlets carries out heat exchange; Absorb behind the waste heat again through the inlet of pipeline to blower fan 7, send in the blast heater 4 through blower fan 7 then, this air is sent in the baking oven 2 drying tea leaves after in blast heater 4, being heated once more by the heater in the blast heater 4.Because the setting of heat exchanging chamber 3, the cold air in the hot-air heat exchanging chamber 3 that baking oven 2 capable of using is discharged heats, thereby improves the utilization rate of thermal source greatly, has also just improved the heating and the drying efficiency of tealeaves, has practiced thrift the energy greatly.
In order further to improve the utilization rate of thermal source; Pipeline between the inlet of said outlet that is arranged on heat exchanging chamber 3 and blower fan 7 comprises air path pipeline 8 and the preheating pipeline 6 that is arranged on baking oven 2 inner chambers, and said preheating pipeline 6, air path pipeline 8 are arranged sequentially between the inlet of outlet and blower fan 7 of heat exchanging chamber 3.Preheating pipeline 6 is arranged on baking oven 2 inner chambers, and the waste heat in the baking oven 2 capable of using carries out heat exchange to the Cryogenic air in the preheating pipeline 6, reaches the purpose that more makes full use of thermal source.In this embodiment, preferably preheating pipeline 6 is arranged on top of chamber in the baking oven 2.The upwards flowability of temperature capable of using in baking oven 2 can effectively be avoided the bake out temperature of tealeaves is formed influence.
In above embodiment, heat exchanger tube 5 arrangements in the heat exchanging chamber 3 can have multiple, be that a row carries out heat exchange as can heat exchanger tube 5 being uniformly distributed with, but in order to make heat exchange more abundant, said heat exchanger tube 5 layering interlaced arrangement are in heat exchanging chamber 3.Like Fig. 3 and shown in Figure 4, the hot-air that makes baking oven 2 discharge fully contacts with heat exchanger tube 5, reaches heat exchange effect preferably.In addition, the material of heat exchanger tube 5 can be selected common steel tube, and as preferred version, said heat exchanger tube 5 materials preferably adopt the stronger aluminum pipe of exchange capability of heat to make.
In above embodiment; The heater of blast heater 4 can adopt modes such as electrical heating, Far-infrared Heating to realize; As optimal way, the said heater that is arranged in the blast heater 4 comprises at least one group of heater 9 and at least one group of electromagnetic induction coil that is connected with AC power 17.After blower fan 7 is blown into cold wind in the blast heater 4, the circuit of electromagnetic induction coil 17 is connected, electromagnetic induction coil 17 produces the high speed variation magnetic field; When the magnetic line of force in the magnetic field passes through heater 9; In heater 9, produce powerful eddy current, and heater 9 itself is in short-circuit condition, so eddy current can make heater 9 heating at a high speed voluntarily under the effect of heater 9 self-resistances; Thereby realized electric energy and heat energy conversion, formed the purpose that the air in the blast heater 4 is heated.Air through heating is being dried tealeaves in the air outlet entering baking oven 2 of blast heater 4 under the effect of blower fan 7.
In the above-described embodiment, heater 9 can only be provided with one group with electromagnetic induction coil 17; In addition; Heater 9 is arranged in the blast heater 4 with electromagnetic induction coil 17 and gets final product; As long as the magnetic line of force that can enable electromagnetic induction coil 17 generations is through heater 9, as optimal way, heater 9 has many groups; Said electromagnetic induction coil 17 is arranged on heater 9 inside, and each heater 9 set inside has plurality of electromagnetic induction coil 17.Make and to carry out two-way heating to heater 9 that make structure more reliable, the thermal efficiency is higher, and is more reasonable to the utilization in blast heater 4 inner structure spaces.And for the heat that heater 9 is produced can fully spill in the blast heater 4, as shown in Figure 2, also be furnished with many group fin 10 at heater 9 outer walls.
For accurately controlling the hot blast temperature in the baking oven 2, in baking oven 2, be provided with at least one heat-sensitive sensor 12, heat-sensitive sensor 12 is electrically connected with controller 13, and controller 13 is electrically connected with electromagnetic induction coil 17.Through these heat-sensitive sensor 12 real-time temperature that detect hot blasts in the baking oven 2, reach electric energy closed or disconnection electromagnetic induction coil 17 through controller 13 then and import, to reach the hot blast temperature in the control baking oven 2.
For ease of the drying operation of tealeaves, baking oven 2 one sides are provided with feed hopper 14, and baking oven 2 bottoms are provided with discharge bucket 15, are provided with multilayer transporting chain plate 16 in the baking oven 2, and transporting chain plate 16 is connected with transmission device 11.Tealeaves gets on the transporting chain plate 16 in the baking ovens 2 from feed hopper 14, and transporting chain plate 16 moves under the effect of transmission device 11, tealeaves after drying from discharge bucket 15 dischargings.
For preventing that the heat in the baking oven 2 scatters and disappears, on the outer wall of baking oven 2, be coated with the insulation layer, thereby can effectively prevent scattering and disappearing of baking oven 2 interior heats, improve oven dry treatment effect to tealeaves.
