This device mainly contains four do action processes: 1. mold heated process 2. hot water removal process 3. mold cools down processes 4. cold water discharge processes
1. mold heated process
When device was started working, magnetic valve V 9 opened, and water through valve S 9 and 9 pipelines of magnetic valve V, in moisturizing container C 3, when liquid level sensor Y 3 detects liquid level arrival, is closed magnetic valve V 9 through magnetic valve V 9 by check-valves S 9; Start small pump M 1 then, the water in the moisturizing container C 3 is got among the hot water collection container C 2, after water enters in the container C 2,, just close small pump M 1 after liquid level arrives when detecting by the level condition that liquid level sensor Y 2 detects the water that enters; Then start heat-exchanger pump M 2, the water among the hot water collection container C 2 is got among the heating container C 1, after water enters in the container C 1,, just close small pump M 2 after liquid level arrives when detecting by the level condition that liquid level sensor Y 1 detects the water that enters; Opening electric heater E heats the water among the heating container C 1 then, and the temperature of heating is detected by temperature sensor K 2, when being heated to desired temperature, closes electric heater E.
When mould M is heated, open magnetic valve V 3 and magnetic valve V 4, and startup heat-exchanger pump M 2, hot water just enters the pipeline between heating container C 1 and the valve S 3, advance check-valves S 3, pipeline between magnetic valve V 3 and valve V 3 and mould M arrives among the mould M mould M is heated, hot water goes out mould M after the pipeline of 4 of mould M and valve V, advance magnetic valve V 4, enter among the hot water collection container C 2 after advancing the pipeline of 4 of valve V 4 and valve S and valve S4 again, water among the hot water collection container C 2 enters into heating container C 1 again through heat-exchanger pump M 2 behind 10 pipelines of pump M 2 and valve S and the valve S 10, so just forms a hot water circuit and comes mould is heated; After temperature sensor K 1 on the mould M detects mold temperature and arrived desired temperature, just close heat pump M 2, magnetic valve V 3 and magnetic valve V 4.
In said process, if detecting temperature, the temperature sensor K 2 on the heating container C 1 descends, just opening electric heater E is warmed to the temperature that requires to the water in the container C 1.
On the one hand, in said process, if the pressure sensor P on the heating container C 1 detects above safe pressure, then opens solenoid valve V 5 in addition, and V 6 and V 8 make the pressure in the container C 1 drop to safe pressure.
After heating finished to mould M, the liquid level sensor Y 1 on the hot water tank C 1 carried out the liquid level detection to the hot water of its inside, if liquid level is low, then starts heat pump M, makes the liquid level in the container C 1 reach requirement.
2. hot water removal process
After said process is finished, leave hot water in mould M and the hot water circulating pipeline, need reclaim them return, like this can energy savings.
Open magnetic valve V 2 and magnetic valve V 4, compressed air will be along magnetic valve V 2,2 pipelines of valve V 2 and valve S, pipeline between valve S 2 and mould M, mould M, the pipeline that mould M and valve V are 4,4 pipelines of valve V 4 and valve S and valve V 4 and 2 pipelines of hot water collection container C, be blown among the hot water collection container C 2 by pressure differential leaving hot water in mould M and the hot water circulating pipeline, after all having blown, close magnetic valve V 2 and magnetic valve V 4.
After hot water reclaimed, the liquid level sensor Y 2 among the hot water collection container C 2 detected inner fluid level condition, if liquid level is low, then starts small pump M 1, makes the liquid level in the container C 2 reach requirement.
Simultaneously, the liquid level sensor Y 3 in the moisturizing container C 3 detects inner fluid level condition, if liquid level is low, then opens solenoid valve V 9, make the liquid level in the container C 3 reach requirement.
3. mold cools down process
During cooling, magnetic valve V 1 and magnetic valve V 7 open, and cold water is along magnetic valve V 1, and the pipeline between valve S 1 and the valve V 1 enters mould M, come out from mould M and 7 pipelines of magnetic valve V then, again along the pipeline outflow of 7 of V7 and S.
The mold temperature that detects temperature sensor K 1 on the mould M is just closed magnetic valve V 1 and magnetic valve V 7 after having arrived the desired temperature of cooling, stops cooling.
4. cold water discharge process
After said process is finished, leave cold water in mould M and the cool water circulating pipe road, need blow out them, can prepare for mold heated next time like this.
Opening magnetic valve V 2 opens with magnetic valve V 7, compressed air is along magnetic valve V 2, pipeline between pipeline between valve S 2 and the valve V 2 and valve S 2 and mould M enters mould M, comes out from mould M and 7 pipes of magnetic valve V then, and the pipeline along 7 of V 7 and S flows out again.
After cold water has been arranged, close magnetic valve V 2 and magnetic valve V 7.
