Detailed description of the invention
1,2,3,4,5,6,7 a kind of embodiment of the present utility model is described by reference to the accompanying drawings.
A kind of thermal source built-in double-side heat exchange tunnel type drying room, has framework 1, and the coated insulated wall 2 in the outside of framework 1; Described framework 1 is longitudinally provided with two sides insulated wall 3 and space in insulated wall 2 is longitudinally separated into the air heat district 4 of both sides and middle drying materials district 5, and insulated wall about 3 two ends all have air channel 6 through to air heat district 4 and drying materials district 5; The bottom of the insulated wall 2 outside described air heat district 4 is provided with air inlet 9, combustion furnace 7 and heat exchanger 8 is provided with in air heat district 4, and the air inlet of heat exchanger 8 upper end is connected with the exhaust outlet of combustion furnace 7 upper end, the gas outlet of heat exchanger 8 lower end is connected with smoke exhaust pipe 19; The top in described drying materials district 5 is hung with axial flow blower 10, the bottom in drying materials district 5 is provided with the cold plate 11 of uniform through hole, the below of cold plate 11 is laterally provided with humidity discharging pipe 12, described humidity discharging pipe 12 circumferentially uniform through hole, and the outer end of humidity discharging pipe 12 is extended to outside insulated wall 2, and ventilating fan 13 is equipped with in the outer end of humidity discharging pipe 12.Air inlet bottom described combustion furnace 7 is equipped with air blast 16, and the top of described insulated wall 3 is inwardly provided with horizontal deflector 17, and the below of described humidity discharging pipe 12 is provided with guiding gutter 18.
Be provided with Temperature Humidity Sensor 14 in described drying materials district 5, described air inlet 9 is provided with self closing door 15; The temperature-humidity signal output of described Temperature Humidity Sensor 14 connects the signal input part of PLC respectively, the aperture of the control signal that PLC exports the respectively quantity combusted of control combustion stove 7, the rotating speed of axial flow blower 10, the rotating speed of ventilating fan 13 and self closing door 15, makes the humiture in drying materials district 5 remain at the humiture of PLC setting interval.
Wherein, framework 1 entirety adopts aluminum alloy materials, avoids the corrosion problem in hygrothermal environment, meets state food security regulations, avoid the secondary pollution of food in drying course.Combustion furnace 7 adopts natural gas fired incinerators or liquefied gas combustion furnace, substantially can reach no pollution discharge, environmental protection.Heat exchanger 8 adopts shell and tube interchanger, and heat exchange efficiency is high.Temperature Humidity Sensor 14 adopts temperature sensor and humidity sensor integrated morphology, takes up room little, is conducive to circulative convection.Cold plate 11 is corrugated plating, and condensation effect is good.
The utility model can need several drying room to join end to end use according to user, and one end is charging aperture, and the other end is discharging opening.During oven dry, material is delivered to drying room materials inside baking zone by induction system, simultaneously according to the difference of drying materials time, regulates the transmission speed of induction system.
Operation principle: extraneous cold dry air enters air heat district 4 by air inlet 9, after combustion furnace 7 and heat exchanger 8 heat, carry heat formation hot-air naturally rise to top, air heat district 4, and enter drying materials district 5 from air duct at top 6, flow downward under the effect of axial flow blower 10, flow through by material drying by drying materials, absorb by material drying moisture, temperature reduces, humidity increases, and naturally sinks after becoming clammy air.The heated dry air that part humidity is lower, temperature is higher, by air heat district 4 suction function, is back to air heat district 4 and heats rear continuation participation heat exchange circulation.The through hole of clammy air on cold plate 11 that all the other humidity are comparatively large, temperature is lower, enter humidity discharging pipe 12 and discharge drying room, the condensed water meanwhile condensed out continues to sink down into guiding gutter 18 and discharges drying room.
The utility model drying materials district 5 is while utilizing the natural principle that hot-air rises, clammy air sinks, by the effect of axial flow blower 10, hot-air is flowed downward and form inverse circulative convection mode, drying materials district 5 both sides hot-air is made naturally to increase, the passive decline of middle heat air, clammy air natural sinks, ensure that whole drying materials district humiture stable and uniform, the parameter height after same batch of material drying oven dry is consistent, more easily reaches professional standard and national relevant regulations.And the heated dry air that part humidity is lower, temperature is higher continues to participate in heat exchange circulation, clammy air is discharged by exhausting moisture pipeline after cold plate condensation, and decrease the circulation of clammy air in drying course and participate in, energy-saving effect is remarkable.Compare existing drying room hot-air to enter from material drying bottom, the convection process of discharging from material drying top, decreases thermal losses, more energy-conservation.
The utility model is detected by the multiple spot of Temperature Humidity Sensor 14 in drying course, in real time temperature-humidity signal is fed back to PLC, PLC is according to the humiture parameter preset, distinguish the aperture of the quantity combusted of control combustion stove 7, the rotating speed of axial flow blower 10, the rotating speed of ventilating fan 13 and self closing door 15, the humiture in drying materials district 5 is made to remain at the humiture interval of PLC setting, automatical and efficient, ensure that the parameter height after the oven dry of different batches material drying is consistent.
The utility model carrys out the convection velocity of controlled circulation hot-air by the rotating speed of Based Intelligent Control axial flow blower 10, the quantity delivered of Based Intelligent Control combustion furnace 7 combustion gas and then control its quantity combusted, the aperture of Based Intelligent Control self closing door 15 and then control cold dry air intake, finally reach the object accurately controlling bake out temperature.And when actual humidity reaches the higher limit of drying room setting humidity, open ventilating fan 13 and carry out humidity discharging, reduce humidity, when actual humidity is less than the lower limit of drying room setting humidity, closes ventilating fan, stop humidity discharging.
