For achieving the above object, present invention employs techniques below scheme: a kind of multiple stage battery vacuum drying oven evacuation system
System, including vacuum pump, vacuum pump is connected with multiple baking ovens by stainless steel pipes, the rustless steel that each baking oven connects with vacuum pump
Vacuum valve it is respectively provided with in pipeline, the number of vacuum valve and the number one_to_one corresponding of baking oven, each baking oven is used to record
Battery oven baking time and the timer of delay time at stop, the signal output part of described timer is defeated with the signal of PLC
Entering end to be connected, the signal output part of described PLC is connected with multiple vacuum valves.
Described each baking oven all connects dryer group by dry feed channel, arranges dry air valve in described dry feed channel
Door.
Another object of the present invention is to provide the vacuum pumping method of a kind of multiple stage battery vacuum drying oven pumped vacuum systems, should
Method includes the step of following order:
(1) battery of required baking is put in baking oven, carry out baking process by the baking program control system on baking oven and set
Put and toast；
(2) when separate unit baking oven enters evacuation state, evacuation signal is transferred to PLC by the timer on baking oven,
PLC opens corresponding vacuum valve, makes vacuum pump that this baking oven is carried out evacuation；When multiple stage baking oven enters evacuation shape
During state, the timer on multiple stage baking oven is transferred to PLC by organizing evacuation signal more, and PLC is by each baking oven
Delay time at stop is ranked up, and opens the vacuum valve of correspondence successively, makes vacuum pump that each baking oven to carry out evacuation successively.
Described PLC was ranked up specifically referring to by the baking delay time at stop of each baking oven, described timer record
The actual baking time of baking oven and the delay time at stop of theoretical baking time；PLC by delay time at stop of each baking oven by low to
Height is ranked up, and evacuation successively.
As shown from the above technical solution, the present invention controls single device by increasing PLC, it is ensured that multiple stage vacuum pump need to be taken out very simultaneously
Only separate unit baking oven is carried out evacuation time empty, it is ensured that baking oven vacuum pressure value reaches technological requirement, improves cured effect；Pass through
PLC is to because waiting that the baking oven that evacuation is delayed baking time the longest carries out preferential evacuation, it is ensured that baking time is the shortest,
Improve baking efficiency.Additionally, the present invention is simple to operate, save vacuum pump quantity, save production cost, can be widely popularized.
Accompanying drawing explanation
Fig. 1 is the structural representation of native system.
Detailed description of the invention
As it is shown in figure 1, a kind of multiple stage battery vacuum drying oven 4 pumped vacuum systems, including vacuum pump 1, vacuum pump 1 is by stainless
Steel conduit 3 connects with multiple baking ovens 4, is respectively provided with vacuum valve 7 in the stainless steel pipes 3 that each baking oven 4 connects with vacuum pump 1,
The number one_to_one corresponding of the number of vacuum valve 7 and baking oven 4, each baking oven 4 is used to record battery oven 4 baking time and
The timer 5 of delay time at stop, the signal output part of described timer 5 is connected with the signal input part of PLC 2, described PLC
The signal output part of controller 2 is connected with multiple vacuum valves 7.Described each baking oven 4 all connects drying machine by dry feed channel 6
Group, arranges dry air valve 8 in described dry feed channel 6.PLC 2 is used for controlling multiple stage baking oven 4 evacuation order.Institute
State timer 5 and the baking time of every baking oven 4 carried out record, by holding wire 9, baking time is transferred to PLC 2,
It is easy to PLC 2 evacuation order is controlled；Described dry feed channel 6 is for filling dry gas to baking oven 4, just
In baking oven 4 evacuation and heavily it is dried gas alternately.
When evacuation, first, the battery of required baking is put in baking oven 4, by the baking programme-control on baking oven 4
System carries out baking process setting and toasts；Secondly, when separate unit baking oven 4 enters evacuation state, the timing on baking oven 4
Evacuation signal is transferred to PLC 2 by device 5, and PLC 2 opens the vacuum valve 7 of correspondence, makes vacuum pump 1 to this baking
Case 4 carries out evacuation；When multiple stage baking oven 4 enters evacuation state, the timer 5 on multiple stage baking oven 4 will organize evacuation letter more
Number being transferred to PLC 2, PLC 2 was ranked up by the delay time at stop of each baking oven 4, opened the vacuum of correspondence successively
