An anti-overflow device for a drainage box, an anti-overflow drainage box, and an exhaust method for the drainage box

Abstract

The invention discloses a drainage tank anti-overflow device. The device comprises an exhaust pipe, a grate water housing and an exhaust cap. An anti-overflow drainage tank comprises a water tank, a drainage main pipe and the drainage tank anti-overflow device. According to a specific technical scheme, a drainage tank exhaust method comprises the following steps: manufacturing the grate water housing; welding the grate water housing; mounting the exhaust pipe; mounting the exhaust cap. The drainage tank anti-overflow device, the anti-overflow drainage tank and the drainage tank exhaust method have the advantages that the structure is simple, the manufacturing cost is low and smooth exhaust of a drainage system is guaranteed, so that stable operation of the drainage system is guaranteed, and great practical value and popularization value are achieved.

Description

technical field [0001] The invention relates to the technical field of blast furnace drainage pipelines, in particular to an anti-overflow device for a drainage box, an anti-overflow drainage box and an exhaust method for the drainage box, which are suitable for pipeline drainage systems and have strong practicability in blast furnace drainage. Background technique [0002] In the existing metallurgical industry, the drainage box in the drainage system drains water, especially in the vertical state. During the drainage process from the drainage box to the drainage pipe, the water flow is large and it is easy to bring a large amount of air into the pipe. In the drainage pipe, the water flows down and As the air moves upwards, the relative movement speed of the water flow and the air will increase, which will easily cause the air to carry the water out, that is, the water will turn over, causing the water tank to overflow and affecting the normal operation of the drainage syste...
