Drainage control device of vacuum pump system for papermaking

Abstract

The utility model belongs to the technical field of drainage of vacuum pump systems in the papermaking industry, and relates to a drainage control device of a vacuum pump system for papermaking, which comprises a drainage system arranged between a upstream pipeline and a vacuum valve system, the drainage system is directly connected with a drainage tank, a floating self-drainage system is arranged in the drainage tank, and a first drainage pipe is inserted into the floating self-drainage system. The second drainage pipe is provided with a drainage valve, and the water level monitoring system is in communication connection with the drainage valve and the drainage system. The drainage system is directly connected with the drainage tank, condensate water is continuously drained through gravity, pipeline water accumulation is avoided from the source, the floating self-drainage system is driven by liquid level buoyancy to trigger opening and closing of the first drainage pipe, and external power is not needed; the water level monitoring system accurately controls the drainage valve to realize quick drainage of the second drainage pipe, and the two are complementary to form redundant double-drainage guarantee; current impact caused by the fact that accumulated water instantly flows into the pump body is completely eradicated, the tripping risk is reduced, the service life of the motor is protected, and non-planned shutdown loss is reduced.
