Description

A kind of sheet material drying device
Technical field
The utility model relates to a kind of drying device, particularly a kind of sheet material drying device.
Background technology
In sheet material processing, sheet material need be carried out drying, namely force to make water evaporates loss in the sheet material with manual method, make the moisture content of sheet material be down to the level suitable with local equilibrium moisture content, avoid sheet material to go mouldy or in the erosion of storing, be subjected in transportation and the process used entomogenous fungi and sheet material splitting, distortion.Existing sheet material drying device, utilize hot-blast stove that sheet material is heated, feed steam then to the sheet material damping, cracking and the distortion of sheet material have been prevented, but owing to there is not heat-energy recovering apparatus, caused the waste of heat energy, increased operating cost, and caused unnecessary waste and reduced operating efficiency, made the uniformity of sheet material drying inconsistent.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of sheet material drying device with heat-energy recovering apparatus.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of sheet material drying device, at least comprise hothouse and hot-blast stove, described hothouse has two at least, is provided with intake stack, return air duct, interior circulating fan and humidifying spraying nozzle in the hothouse, and intake stack is connected with hot-blast stove, one side of hot-blast stove is provided with combustion-supporting airduct, on the combustion-supporting airduct valve is installed, the opposite side of hot-blast stove is provided with steam unit, and the steam unit bottom is connected with humidifier, steam unit is connected with humidifying spraying nozzle, and return air duct is connected with hot-blast stove by main air blower; The top of hothouse is provided with weep hole, and hot-blast stove is connected with external circulation air inlet, and hothouse is outside equipped with the controller that is connected with hot-blast stove, and controller also is connected with temperature sensor and the humidity sensor that is arranged in the hothouse.
Preferred as such scheme is equipped with the wind direction converter on the described return air duct.
Described hothouse is body structure, and the sidewall of casing is provided with heat-insulation layer.
The utility model than the beneficial effect that prior art has is: the waste heat of hothouse is sucked back by the return air duct circulation in the utility model, be admitted to again and carry out heat exchange in the hot-blast stove, hot blast after the exchange is sent into hothouse by main air blower again timber is heated, operating cost and operating cost have been saved, hot blast reclaims the circulation behave in the drying chamber, can suck back the waste heat hot blast about 60 ℃~70 ℃, also saved from environment temperature and be heated to the time temperature required in the kiln, thereby reach the highest thermal efficiency, make the uniformity of sheet material drying reach consistent.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawing: circulating fan, 6-humidifying spraying nozzle, the combustion-supporting airduct of 7-, 8-steam unit, 9-humidifier, 10-heat-insulation layer, 11-main air blower, 12-wind direction converter, 13-weep hole, 14-external circulation air inlet, 15-controller in 1-hothouse, 2-hot-blast stove, 3-intake stack, 4-return air duct, the 5-.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further explained.
A kind of sheet material drying device comprises hothouse 1 and hot-blast stove 2 at least, and described hothouse 1 has two at least, and hothouse 1 is body structure, and the sidewall of casing is provided with heat-insulation layer 10.Be provided with intake stack 3, return air duct 4, interior circulating fan 5 and humidifying spraying nozzle 6 in the hothouse 1, intake stack 3 is connected with hot-blast stove 2, one side of hot-blast stove 2 is provided with combustion-supporting airduct 7, on the combustion-supporting airduct 7 valve is installed, the opposite side of hot-blast stove 2 is provided with steam unit 8, and steam unit 8 bottoms are connected with humidifier 9, and steam unit 8 is connected with humidifying spraying nozzle 6, return air duct 4 is connected with hot-blast stove 2 by main air blower 11, and wind direction converter 12 is installed on the return air duct 4; The top of hothouse 1 is provided with weep hole 13, and hot-blast stove 2 is connected with external circulation air inlet 14, and hothouse 1 is outside equipped with the controller 15 that is connected with hot-blast stove 2, and controller 15 also is connected with temperature sensor and the humidity sensor that is arranged at hothouse interior 1.
In the present embodiment, with reference to Fig. 1, sheet material to be processed is placed in the hothouse 1, starts hot-blast stove 2 by controller 15, and air outside enters into hot-blast stove 2 heating by external circulation air inlet 14, the hot blast that heating obtains enters in the hothouse 1 by intake stack 3, interior circulating fan 5 starts, and hot blast is circulated in hothouse 1, and sheet material is carried out heating, drying, the heat that steam in the evaporation sheet material, heat-insulation layer 10 can reduce in the hothouse 1 scatters and disappears; Open steam unit 8 by controller 15 then, steam by humidifying spraying nozzle 10, is sprayed in the hothouse 1, is used for ensureing high humidity environment required in desiccated wood, prevent timber crack, distortion, the steam in the hothouse 1 can regularly be discharged by weep hole 13.Be provided with temperature sensor and humidity sensor in the hothouse 1, by temperature sensor and humidity sensor feedack, controller 15 can be adjusted the heating-up temperature of hot-blast stove 1, and then adjusts the hot blast temperature of carrying, and regulates the amount that humidifier 9 can change the steam of steam unit 8 conveyings.After heating a period of time, start main air blower 11 and wind direction converter 12, hot blast is turned back to the hot-blast stove 2 from return air duct 4 reheat, again by main air blower 11, the hot blast after the heating is sent in the hothouse 1 from return air duct 4 then.The fuel of hot-blast stove 1 can be selected the waste wood in the sheet material processing, wooden slag and dry bark for use.According to the sheet material of unlike material, by the air inflow in the valve regulated hot-blast stove 1 on the combustion-supporting airduct 7, change the ignition temperature of material in the hot-blast stove 1.
