Description
Technical Field
The utility model belongs to the technical field of exhaust apparatus, in particular to an exhaust apparatus for vertical pipeline.
Background
The large-scale equipment such as pond, water pitcher can use the pipeline to drain usually, and when the water head is great, rivers falling speed in the pipeline is too fast, produces the siphon phenomenon easily, and the air can be inhaled in the pipeline (as shown in figure 1), and the air that gets into the standpipe partly continues to flow in horizontal pipeline along with the rivers, but when vertical pipeline is enough long-term, more air accumulation forms the bubble in vertical pipeline, can hinder the whereabouts of rivers after the bubble is produced, makes the interior water level of pond rise even. The air bubbles are accumulated to a certain degree, so that the buoyancy of the bubbles is greater than that of water columns on the bubbles, the bubbles gradually rise, the water columns on the bubbles gradually shorten, the resistance to the bubbles gradually decreases, the rising speed of the bubbles is faster and faster, and finally a certain amount of water is wrapped along the pipeline to flush out, so that a splashing phenomenon is formed, the splashing strength is different due to the length of the vertical pipeline (namely the fall between the water level of the water pool and the water level of the horizontal pipeline), the height of the splashing strength can reach more than 5 meters, the splashed water often falls out of the water pool and the pipeline, and the splashing strength is not allowed in most application occasions, particularly when harmful sewage is conveyed.
For air entering the horizontal duct, an exhaust valve is typically employed to evacuate it. The vertical pipe is not provided with a corresponding exhaust device, and one measure for reducing the splashing phenomenon at present is to change a first elbow into a tee joint (as shown in figure 2), so that when water flows from the horizontal direction to the vertical direction, a part of air is discharged from an upper outlet of the tee joint, and the formation of bubbles in the vertical pipeline can be reduced, thereby reducing the splashing. However, this improvement only reduces the occurrence of splashing and does not completely eliminate it and does not solve the problem of re-collection of the splashing water stream.

When the vertical pipeline is too long and the rising water amount is too large, the buffer water tank can be heightened to increase the volume.
The utility model adds a splash-proof reflecting cover and a buffer water tank which can collect the splash water on the basis of the tee joint, and simultaneously, a return pipe is arranged between the buffer water tank and the water inlet pipe, thereby solving the problem of re-collection of the splash water flow; the upper part of the buffer water tank is in an opening shape, and a gap is formed between the reflecting cover and the buffer water tank, so that air flow in the vertical pipeline can be conveniently discharged into the atmosphere; the end of intaking of base has set up the check valve board for rivers can flow in the outlet end from the inlet tube, and in the unable reverse entering inlet tube when splash rivers rise, avoid forming the splash phenomenon in the pond.
