Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, and particularly relates to a sewage discharge device for a cooling tower. Background Art

[0002] In an industrial cooling system, a cooling tower plays a crucial role in maintaining the normal operating temperature of equipment by continuously dissipating heat. However, with the continuous use of the cooling tower, scale inevitably forms inside it. When the scale is dissolved by chemicals, it will fall from the inner wall of the cooling tower into the water collection frame. Subsequently, a water pump is used to pump out the wastewater containing dissolved scale in the water collection frame to achieve the purpose of cleaning and sewage discharge.

[0003] Since the existing sewage discharge device lacks an effective filtering structure and cannot intercept and filter the scale particles in the wastewater, these scales are pumped out by the water pump together with the wastewater, and are very likely to gradually deposit and accumulate inside the water pipe, and may eventually cause the water pipe to be blocked. The blockage of the water pipe will seriously affect the normal sewage discharge function of the cooling tower, so there is a problem that it is not convenient to filter the scale.
