Background technology
Casting films after the casting machine curtain coating gets into drying baker and carries out drying.At present; The drying alley of the drying baker of casting machine is provided with air inlet, exhaust outlet and return air inlet, and breeze fan is connected with air inlet on the drying alley through heating cabinet, delivers in the drying alley after new wind is heated; Hot blast flows in drying alley; The damp and hot wind process of part return air fan is delivered to the air inlet of drying alley, realizes hot air circulation, helps the drying of casting films; The damp and hot wind of another part is discharged through exhaust outlet.Damp and hot wind-warm syndrome degree through exhaust outlet is discharged is higher, has certain heat energy, is discharged into the energy consumption that has increased dryer in the air, causes the waste of mass energy.
The utility model content
The utility model is in order to overcome weak point of the prior art, a kind of casting machine drying baker with energy recovery function to be provided, can reclaim the heat energy of the damp and hot wind of casting machine drying baker, cut down the consumption of energy, reaching purpose of energy saving.
The utility model is realized through following technical proposals:
A kind of casting machine drying baker with energy recovery function; It is characterized in that; Comprise that drying alley, breeze fan, heating cabinet, air draft blower fan, return air fan, hot blast reclaim heat exchanger, said drying alley is provided with air inlet, exhaust outlet and return air inlet, and the air outlet of breeze fan is connected with the air inlet of drying alley through heating cabinet; Return air inlet on the drying alley is connected with the air inlet of return air fan through return air channel, and the air outlet of return air fan is connected with the air inlet of drying alley; The exhaust outlet of said drying alley is connected with the air inlet of air draft blower fan through air exhaust passage; The air outlet of said air draft blower fan is leaded up to first air-valve and is connected with the air inlet of breeze fan; Another road is connected with the air draft import that hot blast reclaims heat exchanger through second air-valve, and the new wind outlet that said hot blast reclaims heat exchanger is connected with the air inlet of breeze fan through the 3rd air-valve.
Said hot blast reclaims on heat exchanger wind exhausting outlet and the fresh inlet and is separately installed with the 4th air-valve and tendencies valve.
Temperature sensor and humidity sensor are installed in the said drying alley; Said temperature sensor is connected with the temperature-humidity signal input of automatic controller respectively with humidity sensor, the control signal output of said automatic controller respectively with the heating control end of heating cabinet, breeze fan, air draft blower fan, return air fan, air draft blower fan and breeze fan between first air-valve, air draft blower fan and hot blast reclaim the tendencies valve that second air-valve of heat exchanger air draft import department, the 3rd air-valve that hot blast reclaims the new wind of heat exchanger exit, the 4th air-valve, hot blast that hot blast reclaims heat exchanger wind exhausting outlet place reclaim heat exchanger fresh inlet place and be connected.
The utlity model has following technique effect:
1, the exhaust outlet of the casting machine drying baker of the utility model connects the air draft blower fan through air exhaust passage; Damp and hot wind is delivered to the air inlet of breeze fan through the air draft blower fan; Directly send into the damp and hot wind of discharging in the drying alley; Form the interior circulation of hot blast of sealing, both had draught effect, thermostatic effect is arranged again.Because the new wind of no low temperature gets into and the discharge of hot blast, and has reclaimed the heat of hot blast, avoided the waste of heat energy, reach purpose of energy saving.
2, the exhaust outlet of the casting machine drying baker of the utility model is connected with hot blast recovery heat exchanger through air exhaust passage and air draft blower fan; Get into heating cabinet through breeze fan again after the new wind of low temperature of entering hot blast recovery heat exchanger absorbs the air draft heat, improved the interior new wind-warm syndrome degree of entering heating cabinet, afterwards; New wind after the heating gets into the dry casting films of drying alley again; Can practice thrift the energy that heating cabinet is used to heat new wind, thereby cut down the consumption of energy, reach purpose of energy saving.
Description of drawings
Fig. 1 is the sketch map that the utlity model has the casting machine drying baker of energy recovery function.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Fig. 1 is the sketch map that the utlity model has the casting machine drying baker of energy recovery function; Comprise that drying alley 3, breeze fan 1, heating cabinet 2, air draft blower fan 5, return air fan 4, hot blast reclaim heat exchanger 6; Said drying alley 3 is provided with air inlet, exhaust outlet and return air inlet; The air outlet of breeze fan 1 is connected with the air inlet of drying alley 3 through heating cabinet 2; Return air inlet on the drying alley 3 is connected with the air inlet of return air fan 4 through return air channel, and the air outlet of return air fan 4 is connected with the air inlet of drying alley 3.The exhaust outlet of said drying alley 3 is connected with the air inlet of air draft blower fan 5 through air exhaust passage; The air outlet of said air draft blower fan 5 is leaded up to first air-valve and is connected with the air inlet of breeze fan 1; Another road is connected with the air draft import 10 that hot blast reclaims heat exchanger through second air-valve, and the new wind outlet 9 that said hot blast reclaims heat exchanger 6 is connected with the air inlet of breeze fan through the 3rd air-valve.
In order to realize automatic control, hot blast reclaims on heat exchanger wind exhausting outlet 8 and the fresh inlet 7 and is separately installed with the 3rd air-valve and the 4th air-valve.Temperature sensor and humidity sensor are installed in the said drying alley; Said temperature sensor is connected with the temperature-humidity signal input of automatic controller respectively with humidity sensor, the control signal output of said automatic controller respectively with the heating control end of heating cabinet, breeze fan, air draft blower fan, return air fan, air draft blower fan and breeze fan between first air-valve, air draft blower fan and hot blast reclaim the tendencies valve that second air-valve of heat exchanger air draft import department, the 3rd air-valve that hot blast reclaims the new wind of heat exchanger exit, the 4th air-valve, hot blast that hot blast reclaims heat exchanger wind exhausting outlet place reclaim heat exchanger fresh inlet place and be connected.
When wind exhausting outlet 8 and fresh inlet 7 were closed simultaneously, drying alley return air inlet → return air fan → drying alley air inlet → drying alley → drying alley return air inlet formed interior circulation air path, only plays draught effect.Drying alley exhaust outlet → air draft blower fan → breeze fan air inlet → heating cabinet → drying alley air inlet → drying alley → drying alley exhaust outlet forms another interior circulation air path; When temperature is lower than setting value; Heating cabinet work makes temperature stabilization in setting range, and existing draught effect has thermostatic effect again.Because the new wind of no low temperature (environmental air) gets into and the discharge of hot blast, the good heat insulating of casing and pipeline realizes that the first step is energy-conservation in addition.
When relative air humidity in the drying baker and temperature reach setting value; The water content of air is than higher in the drying baker; Open the 4th air-valve and the tendencies valve on the fresh inlet 7 on the wind exhausting outlet 8 this moment simultaneously, and close first air-valve between air draft blower fan and the breeze fan.Indoor air → fresh inlet → hot blast reclaims heat exchanger → new wind outlet → breeze fan air inlet → heating cabinet → drying alley air inlet → drying alley exhaust outlet → air draft blower fan → hot blast and reclaims heat exchanger air draft import → hot blast recovery heat exchanger → hot blast recovery blower fan wind exhausting outlet → indoor air.Reclaim heat exchanger through hot blast this moment, utilizes the heat of air draft that new wind is heated, and reclaimed the part heat of air draft, realized that second step is energy-conservation.
