The multitube jet aerator
Technical field
The utility model relates to the aeration oxygen replenishing device of aeration of stretches device, particularly fishpond.
Background technology
Existing fishpond oxygenating machine, as vane type, water wheel type, spray-type and inflatable etc., its common weak point that exists is that active area is less, the dissolved oxygen oxygenation effect is still not good enough.Other has a kind of jet aerator, has the miscible pipe of high speed water jet, induction chamber and air water, makes air water fully mixed, oxygen dissolved height, and jet flow far firing range, but because its single way jet only, effect waters scope is narrow, and active area is still less than normal.
Summary of the invention
The purpose of this utility model is that existing jet aerator is carried out technological improvement, thereby a kind of not only oxygen dissolved height is provided, and can be to the high-level efficiency oxygenating machine of the comprehensive big area oxygenation in waters.
Technical solution of the present utility model is: it comprises submersible pump, thrust-augmenting nozzle, water jet, induction chamber and miscible pipe, its thrust-augmenting nozzle lower end is connected with the potentiality pump discharge, the upper end is connected with the current distribution chamber, the all sides of this current distribution chamber are evenly equipped with the radially water jet more than 3, the current distribution chamber outside that is provided with water jet is covered with induction chamber, and the induction chamber radial equipartition has the miscible interface tube pipe corresponding to each water jet of current distribution chamber
But the exit end of miscible pipe also is connected with the elbow of flexible jet direction.
The beneficial effects of the utility model are: air water is fully mixed, the oxygen dissolved height, and comprehensive injection, and current far firing range, thereby the effect water surface area is big, oxygenation efficient height; This machine is simple in structure simultaneously, and assembling not only is used as the waters aeration oxygen replenishing flexibly, also can add soup or liquid manure, even dispenser fertilising is carried out in the waters, can remove the oxygen-increasing device on submersible pump top again to induction chamber, loading onto pipe connecting and transform water pump into, is the Multi Role Aircraft of a tractor serves several purposes.

Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Submersible pump 7 adopts high pressure diving pump, submersible pump 7 outlets connect the lower end of thrust-augmenting nozzle 6, the upper end of thrust-augmenting nozzle 6 is connected with short cylindrical current distribution chamber 2, and short cylindrical current distribution chamber 2 all sides are evenly equipped with 6 radial taper water jets 3, and current distribution chamber 2 upper port are movably installed with sealing cover 9 with bolt.Induction chamber 1 shroud is outside current distribution chamber 2, its bottom is connected on the thrust-augmenting nozzle 6, top movable is equipped with calotte 8, and all sides are evenly equipped with the radially miscible interface tube pipe 11 corresponding to each water jet 3 of current distribution chamber, and each miscible interface tube pipe 11 is positioned on the same central axis with corresponding water jet 3.Connect miscible pipe 4 on miscible interface tube pipe 11, the exit end periphery of miscible pipe 4 is evenly equipped with screw 12, but uses bolt 13 connecting bends 14.The outlet that changes connecting bend 14 towards, can change the spray angle and the direction of dissolved oxygen current, thereby make current up or down or tilt to inject in the waters as required, fully stir the waters or make water surface aeration.The draw ring 10 of said apparatus by being provided with on submersible pump 7 and the thrust-augmenting nozzle 6, buoyancy aid 5 and the timber made of rope and rigid foam are connected, and device is positioned in the waters.
