Accompanying drawing explanation
Fig. 1 is schematic top plan view of the present utility model.
Fig. 2 is the utility model schematic side view.
The specific embodiment
Below the utility model is described in further detail, referring to Fig. 1 to Fig. 2, the few air flash dryer of a kind of continous way, comprise drier casing 1, transfer roller 2 and be arranged in described transfer roller 2 for carrying the bracket 3 of goods, on described drier casing 1, be provided with the heat supply wind furnace 4 for drier casing 1 is heated, described heat supply wind furnace 4 is connected with described drier casing 1 by heat supply airduct 40, also comprise the circulation airduct 5 that is communicated with described drier casing 1 front end and described heat supply wind furnace 4, described circulation airduct 5 connects the first blower fan 7.Described drier casing, according to the difference of the drying mode of goods, is defined as dryer section by drier casing front end part position, and the part except dryer section is defined as cooling section.Above-mentioned heat supply wind furnace 4 comprises combustor and housing.
Also comprise and take out warm-air pipe 6, described in take out warm-air pipe 6 and be communicated with described drier casing 1 rear and front ends, and described in take out warm-air pipe 6 and be connected by pipeline with described the first blower fan 7.The described warm-air pipe of taking out utilizes the draft of heat supply blower fan to extract the waste heat gas that cooling section goods produce when cooling out, and this waste heat gas is sent into recirculation in dryer section.Also comprise and be arranged at the humidity discharging airduct 8 of described drying box 1 front end and be arranged at the second blower fan on this humidity discharging airduct 8, described the second blower fan is controlled by PLC, at described drier casing 1 front end, be provided with Temperature Humidity Sensor, described Temperature Humidity Sensor is connected with described PLC.Described humidity discharging airduct is with Temperature Humidity Sensor, to detect temperature and the humidity of recyclegas in dryer section, automatically controls the second blower fan, to realize the humidity in automatic control dryer section.Described humiture driver temperature signal is delivered to intelligence instrument simultaneously or PLC processing output signal regulates combustor combustion power automatically.
At described heat supply wind furnace 4, be also provided with the thermocouple for detection of heat supply wind furnace heat outputting gas temperature, described thermocouple connects described PLC, and described PLC controls described heat supply wind furnace 4.Described thermocouple is for detection of hot-blast stove heat outputting gas temperature signal, and temperature signal delivered to intelligence instrument or PLC processes output signal control combustion machine combustion power, to reach the object of temperature in automatic stabilisation dryer section.
Described drier casing 1 front end is also provided with entrance overhead door 10, on described entrance overhead door 10, optoelectronic switch is set.When described optoelectronic switch detects the bracket arrival of carrying goods, automatically open entrance overhead door, goods bracket cuts out entrance overhead door after entering dryer section; At described entrance overhead door 10 rears, be also provided with isolation overhead door 11, on described isolation overhead door 11, optoelectronic switch is set, when the optoelectronic switch on described isolation overhead door detects the bracket arrival of carrying goods, automatically open isolation overhead door, goods bracket cuts out isolation overhead door after entering into cooling section automatically.Described entrance overhead door and isolation overhead door are by compressed air-driven.
Supporting plate operation continuously in drier passage of dried product is loaded in the carrying of the utility model roller-way, in the hot blast being produced by hot air supplier and drier, form closed circuit circulatory system, in whole dry run, constantly recirculated hot air is heated, and the temperature and humidity in the device that keeps dry, in hot air circulation process, in goods, moisture is constantly evaporated in the hot-air of circulation, reach drying purpose, undue humid air is discharged drier in time by the second blower fan.In dry run, in overwhelming majority time drier dryer section, keep high temperature, high wet condition.According to drying system requirement, the goods of being carried continuously by roller-way carry out a series of operation in drier, and first goods inhale warm humidity discharging heat and moisture preserving, humidity discharging hydrofuge by dryer section, and goods move to continuously cooling section and cool, and dry run finishes.In whole intensification, insulating process, only when combustion-supporting, feed a small amount of air combustion-supporting for combustor, do not have again other air to enter in drier, so the few air rapid draing principle of continous way is just that dry run adopts minute quantity air for goods being dried under the state of high temperature, high humidity toward drier, can accomplish that thermal losses is few, energy-conservation, energy is continuous drying goods fast, and improve product percent of pass, are specially adapted to the continuous drying of large part goods.
Practical this device can reduce product dried energy consumption, and arid cycle is short, and product dried is very even, can not cause because of uneven drying the phenomenons such as goods cracking.The utility model is not subject to the restriction of single-piece product size size, and for products thickness, at 10～50mm, moisture is all suitable at the goods below 20～30%, and dry rear goods moisture can be down to 0.4%～1%.
