The time-delay protection energy-saving temperature controller is set with the power-off time of 30 minutes and the power-on time of 5 minutes.

The humidity controller has a set humidity value of 5%.

The humidity controller and the time-delay protection energy-saving temperature controller are directly purchased from the market and belong to the prior art.

The utility model discloses automatic hydrofuge controlling means of disappearance mould casting die cluster baking house is through the air discharge fan that is used for the single phase power of hydrofuge at baking house suitable position installation, replaces the hydrofuge pipeline of taking the control valve among the prior art, and the air discharge fan power cord concatenates the energy-conserving temperature controller of time delay protection, and the temperature controller is long 30 minutes and long 5 minutes when the circular telegram when can setting for the power off, operates as follows:

1. the mould cluster in the stove is under the hot gas flow effect, the steam that produces does not discharge first, but the stuffiness 30 minutes, and the purpose is for accelerating the temperature rise to do not cause the heat loss, makes the mould cluster receive the heating from the surface and inside whole, and makes inside and outside humidity difference and the temperature difference of mould cluster less, is favorable to the inner and outer skin all to obtain the temperature rise simultaneously, ensures that the mould cluster inside can heat to, is favorable to the drying of inside.

2. After the furnace is sealed for 30 minutes, the power is switched on for 5 minutes to enable the exhaust fan to work, and a large amount of steam is discharged; after the time of the time-delay protection energy-saving temperature controller is set, the time-delay protection energy-saving temperature controller can work repeatedly, completely realizes automatic control and is very convenient.

3. After each circulation, the water-containing mould cluster is dried slowly, the humidity in the furnace is reduced gradually, when the humidity in the furnace is less than 5%, because the exhaust fan is not meaningful for exhausting humidity, the humidity controller acts to stop exhausting because the exhaust fan is not electrified.

The utility model discloses automatic dehumidification controlling means of disappearance mould casting die cluster bakery has following technical characterstic and beneficial effect:

1. the heating of the die cluster is fast, no heat loss is caused, and the energy-saving effect is good.

2. Automatic control is realized, and the operation is convenient and efficient.

3. Simple structure, low manufacturing and maintenance cost and convenient popularization.

Detailed Description

The automatic moisture-removing control device for the evaporative pattern casting cluster baking room of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the automatic dehumidification control device for the Evaporative Pattern Casting (EPC) module baking room of the present invention comprises a baking room wall 1, an air inlet pipeline arranged at the lower part of the baking room wall, a heat circulation fan with built-in electric heating arranged at the middle part of the wall cover of the baking room, an exhaust fan 2 arranged at the upper part of the baking room wall 1, a humidity controller 4 with a sensor arranged in the baking room, a time-delay protection energy-saving temperature controller 5, a power switch 6 and a 220V power supply 7; the baking room wall body 1 comprises four walls and a cover top; the time-delay protection energy-saving temperature controller 5 and the power switch 6 are arranged outside the baking room; the exhaust fan 2, the humidity controller 4, the time-delay protection energy-saving temperature controller 5 and the power switch 6 are connected in series through wires and then connected to a 220V power supply 7; the power-off time and the power-on time of the time-delay protection energy-saving temperature controller 5 are respectively set to be 30 minutes and 5 minutes; the humidity controller 4 sets the humidity value to 5%.

The utility model discloses automatic dehumidification controlling means of disappearance mould casting die cluster baking house's operating procedure as follows:

1. the on/off time of the time-delay protection energy-saving temperature controller 5 is set to be 5 minutes and 30 minutes respectively at one time, and the humidity value of the humidity controller 4 is set to be 5 percent.

2. When the die cluster is pushed into the baking room, the door is closed, and the whole baking room is basically in a closed state; the electric heating of the circulating fan is started, and the exhaust fan 2 is started and is in an automatic control state.

3. Baking house heating intensifies, mould cluster moisture evaporation, early stove internal humidity is big, set for to close for electric time for 30 minutes, make exhaust fan out of work in this period of time, the stove steam is not arranged outward earlier but smoldering furnace 30 minutes, make the mould cluster all obtain the heating from the table to the lining to make the inside and outside humidity difference of mould cluster and difference in temperature all less, be favorable to the ectonexine all to obtain simultaneously and heat, ensure that the mould cluster is inside can heat to, it is favourable to inside drying.

4. After the furnace is sealed for 30 minutes, the exhaust fan is automatically turned on, a large amount of steam is discharged, and the power is turned off after 5 minutes.

5. And the circulation is repeated until the humidity is smaller than the set value, the exhaust fan does not work even when the time for electrifying the energy-saving temperature controller 5 for 5 minutes is up to the set value, and the heat is prevented from being discharged outside.

After the above-mentioned many cycles, the die cluster containing water is dried slowly, the humidity in the stove is reduced gradually, when the humidity in the stove is less than 5%, it is meaningless to turn on the exhaust fan 2 again to exhaust humidity, at this moment the humidity controller 4 acts and closes the exhaust fan 2.
