Description
Technical field
The utility model relates to a kind of emptying collecting tank, relates in particular to a kind of emptying collecting tank tank level control system, belongs to the chemical industry equipment field.
Background technology
In producing PET Process, need with using the emptying collecting tank, the more difficult control of liquid level in traditional emptying collecting tank, need to regulate the speed of emptying collecting tank to feed in drainer manually.For the maximization production line, if need workman's manual operation, waste a large amount of artificial, and the more difficult assurance of emptying collecting tank liquid level control accuracy.Therefore seek a kind of liquid level control accuracy higher, save artificial emptying collecting tank tank level control system particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of liquid level control accuracy higher, saves artificial emptying collecting tank tank level control system.
The purpose of this utility model is achieved in that a kind of emptying collecting tank tank level control system, comprise emptying collecting tank and drainer, the discharging opening of described emptying collecting tank is provided with discharge pipe, be provided with rear pump on described discharge pipe, the rear end of described discharge pipe is connected in parallel to drainer feeding pipeline and emptying collecting tank feed back pipeline, the rear end of described drainer feeding pipeline is connected with the charging aperture of drainer, the rear end of described emptying collecting tank feed back pipeline is connected with the feedback outlet of emptying collecting tank, be provided with inlet valve on described drainer feeding pipeline, be provided with liquid level sensor on described emptying collecting tank, be provided with control circuit between described liquid level sensor and inlet valve, be provided with fluid level controller on described control circuit.
Compared with prior art, the beneficial effects of the utility model are: the utility model passes through the aperture of the signal controlling inlet valve of control circuit, thereby controls the feeding speed to drainer, guarantees that emptying collecting tank liquid level is able to accurate control.It is higher that this emptying collecting tank tank level control system has the liquid level control accuracy, saves artificial advantage.
