2) open the feed liquor concentrator again, detect the flow of input duct by electromagnetic flowmeter, pass to controller, controller is judged the open and close of liquid flowing valve on the control feed tube according to flow, give the concentration pan liquid make-up;
By after the heat exchanger heat exchange, control automatic valve and drainage pump for condensated water by controller again, so that the condensed water of heat exchanger condensed water and terrace evaporative condenser enters recycling can after converging when 3) concentration pan is concentrated.
The method for concentration of above-mentioned a kind of Chinese medicine extract, described automatic valve and drainage pump for condensated water adopt same signal Synchronization Control.
For realizing said method, a technical scheme provides the device that solves this technical problem after of the present invention, this device comprises the feed liquor tank, the feed liquor tank connects concentration pan by feed tube, the concentration pan top is connected with condenser overhead by condenser pipe, the concentration pan pipeline connects heat exchanger, the water seal surge tank is connected with terrace evaporative condenser bottom pipeline, the drainage pump for condensated water pipeline connects recycling can, the pipeline that described feed liquor tank is connected with concentration pan is provided with filter, pipeline between inspissator and the filter is provided with electromagnetic flowmeter, heat exchanger and water seal cushion tank connected pipeline and are provided with automatic valve and drainage pump for condensated water, the connecting line of condenser and recycling can is provided with the water seal surge tank, the water seal surge tank is provided with automatic water compensating valve, and the signal output part of electromagnetic flowmeter is connected drainage pump for condensated water with the signal input part of controller, automatic valve, the automatic water compensating valve signal input part is connected with the signal output part of controller.
Further, the concentrated device of above-mentioned Chinese medicine extract, described concentration pan is the economic benefits and social benefits concentration pan.
Further, the concentrated device of above-mentioned Chinese medicine extract, described automatic valve are connected input and are connected the same control signal output of controller with drainage pump for condensated water.
Further, the concentrated device of above-mentioned Chinese medicine extract, described condenser bottom also is provided with vavuum pump.
Compared with prior art, technical scheme elimination provided by the invention vacuum leak, reduced workload, make production more orderly, can find more quickly failure cause to be embodied in the following aspects:
1, increase by an electromagnetic flowmeter for detection of the feed liquor flow in input duct, electromagnetic flowmeter survey is based on Faraday's electromagnetic induction law, detected fluid is necessary for conductor fluid, when the feed tube entrained air, the flow that measures can reduce rapidly, on software, on automatic program, add a determining program, liquid level reaches liquid feed valve should open the time, after the mensuration flow is less than certain numerical value and certain time, the positive closing liquid feed valve also ejects the low warning of flow on the PC screen of operation, press SR and just continue feed liquor after the staff is switched the feed liquor tank; Increase simultaneously feed liquor tank low alarm, when liquid level is lower than certain altitude, eject the low warning of feed liquor tank liquid level on the PC screen, remind the staff to prepare to switch the feed liquor tank.On the basis of the above, when two effect low vacuums during in value that one sets, liquid feed valve also can be forced closed;
2, add automatic valve at this tank filling pipe, when opening of device, automatic water supplement one minute has been avoided the surge tank lack of water, causes vacuum leak;
