Float type water discharge device for cooling tower

Abstract

The invention discloses a float type water discharge device for a cooling tower. The device comprises a filter screen box, a float flow guide mechanism and a sealing element, wherein the filter screen box is of a prismatic structure or a cylindrical structure; a plurality of filter holes are formed in each surface of the filter screen box; the float flow guide mechanism comprises a guide rail and a float mechanism; the guide rail is vertically arranged at the middle position of the upper surface of the filter screen box; a limiting element is arranged at the top of the guide rail; the float mechanism is movably arranged on the guide rail; the sealing element is arranged around the lower surface of the filter screen box. Compared with the prior art, the device has the advantages that the filter screen box is arranged at a water outlet of the cooling tower, and the float mechanism is movably arranged on the guide rail, and moves to a water surface along with a water flow, so that initial-state vortexes are directly eliminated on the surface of a water body, and the vortexes are completely prevented from growing into suction vortexes; in addition, the float flow guide mechanism is externally arranged, so that difficulties in machining and mounting are greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of cooling tower equipment, and in particular relates to a water outlet device of a float type cooling tower. Background technique [0002] In the field of industrial technology, circulating cooling water is generally used to cool large-scale industrial equipment or to cool indoors through circulating cooling water in a central air conditioner. After the heat exchange between the cold water and the equipment is completed, the high-speed hot water is sent to the cooling tower through the water pipe, and after the heat exchange is completed in the cooling tower, the cooled water is sent back to the refrigeration equipment through the outlet pipe for recycling. [0003] The water outlet of the cooling tower produces a vortex due to the high water flow velocity. At this time, the negative pressure in the center of the vortex is easy to inhale air and cause the water pump to have the risk of cavitation. In the p...

Problems solved by technology

However, for the unstable working water level in the cooling tower, these grilles can only eliminate the vortex of the suction screen and the inlet of the pipe. When the water level is more than 50mm above the filter screen, these grilles can no longer eliminate the vortex of the water surface. Rotation, resulting in suction alarm and shutdown, and even the danger of equipment damage
