Description

Rotating pump up aeration machine

Technical field

The present invention relates to a kind of environmental protection, biochemical purification, used for aquiculture aeration and cleaning equipment, particularly make the aerator and the biochemical purification equipment of water motion with parts.

Technical background

In the prior art, use aerator to dissolve into more gas water is purified by pernicious gas effusion and Xiang Shuizhong in the water.Main purpose be increase water oxygen often be called aerator.Drop type, Waterwheel-type, pump impeller formula, vane type, inflatable, plug-flow air suction type, water burst formula, water jet, jetting type, propeller type etc. are arranged.The said equipment has the impeller of driven by motor rotation and the support coupling member on the water surface thereof mostly: as support, floating drum, shaft coupling, impeller bearing, reduction box etc.Biocoenosis decomposing harmful substances in the favourable water, the biochemical purification equipment of increase water oxygen and benefit materials, wherein rotating disc type has better effects.The said equipment all has complex structure, inefficient shortcoming.

Summary of the invention

For better aeration clean-up effect, according to " double-film theory " that majority admit, water contacts with air that relative velocity is big more, and contact area is big more, and time of contact, long more aeration effect was good more.And prior art obviously all respectively has deficiency.Water jet like satisfying above-mentioned requirements, but water is the ejection of---runner---nozzle through water pump.Energy is through conversion loss is very big several times, and the water yield is very little, and efficient is very low.At present the usage amount maximum is generally acknowledged most effective vane type, causes hydraulic jump, whirlpool by stirring water, and water fully refinement and air contact area is little, has wasted a lot of energy, and efficient is still low.Have only abundant improvement the deficiencies in the prior art could obtain high efficiency.

Aerator of the present invention, the critical piece that acts on water are the impellers of driven by motor rotation, and shape does not have the diagonal pumps impeller of pump case similar to one, and its forward and backward cover plate extends in the vertical becomes urceolus and inner core.The urceolus of elongation enters water body and plays suction chamber, and oral area promptly is a suction inlet.Delivery port is on the water surface.During the impeller rotation that constitutes by axle, blade, inner core, urceolus, water axially enters from suction inlet, the closed flow that relies on inner core and urceolus to constitute reaches and with the twisted tilted blade of axle water is quickened gradually, raising speed, required throwing according to required throwing raises angle and throws from the impeller delivery port and raise in the air, water and windage, infiltration, exchange, refinement fall into water body or gatherer by required height, distance and drop size.Usually impeller is shorter, and its blade is designed to a segment structure, has water lift and function is raised in throwing.When the impeller urceolus was longer, its blade was designed to two segment structures, lower end tool water lift function, and the upper end mainly is to throw to raise function.Long urceolus can suck the water than deep layer; When needs are inhaled the more water of deep layer, can lead to required water layer at urceolus suction inlet socket straight tube; When needs are inhaled a certain required waters water, can lead to required waters at urceolus suction inlet socket bend pipe.The throwing of impeller water outlet saliva is raised angle and can be selected between 0 ° to 90 °; Effective greater than 20 ° of aerations; 30 ° to 50 °, especially in the time of 45 °, there is throwing farthest to raise distance.Raising distance when throwing can not be too big, when water droplet needs abundant refinement again, gets 50 ° to 80 °.Throwing just becomes the water lift utensil when raising the function reduction.Usually impeller is an integral body, and intensity is good.For arts demand, blade can be coaxial rotation together, inner core, urceolus are static; Rotate with urceolus or inner core but also blade is coaxial, and inner core or urceolus are static.Also can be spliced into a circular impeller at circumference by many independent runners.Usually adopt motor in last layout, pump up water, reduced efficient because of the support coupling compoonent inevitably will stop part throwing.Adopt motor under when arranging, impeller pumps up water at water surface upthrow, does not have parts to stop, forms a complete drowning circle when falling into water body or gatherer, motor obtains the cooling of water in water simultaneously, but needs the higher waterproof machine of price.

Aerator main working parts of the present invention has only an impeller, and it quickens water gradually, does not have the conversion loss of intermediate energy, and water and windage, infiltration, exchange, refinement aeration are effective, thereby efficient height simple in structure.
