Abstract
The utility model relates to the improvement of a mixed oxygenator of oxygen gas-water, and dissolved oxygen efficiency is enhanced by the change of a structure. An oxygen increase machine is composed of a motor (1), an outer sleeve (11), a hollow shaft, a rubber bearing (14), a propeller (15), etc. The head end of the hollow shaft is provided with a blade (9) to accelerate input rate and enlarge air input. The utility model is especially suitable for purifying the water body of the aquaculture.
Description
The utility model relates to the improvement of gas-vapor mix device, in particular for the oxygenating machine of aquaculture.
Be the aerator of being produced by U.S. A Ruishen (AERATION) company with the comparatively approaching oxygenating machine of the utility model in the prior art, this device has been applied for world patent, i.e. WO85/01887.When operating this device, make its afterbody entry, along with the rotation of motor, the propeller that is located at the aerator afterbody produces the vacuum zone in water, make air via the gas inlet that surfaces, enter tubular shaft, finally enter the water of powerful eddy current, and fully mix with water and form a large amount of tiny bubbles from diffuser tube, because of bubble little, can prolong time that stops in the water and the contact area that increases air and water, thereby improve the concentration of water oxygen, reach the purpose of purifying water body.
The utility model is intended to improve prior art constructions, by strengthening air input and accelerating intake velocity, improves the dissolved oxygen effect.
The member of device described in the utility model comprises motor, outer sleeve, tubular shaft, fan blade, rubber-supporting bearing and propeller at least, and wherein motor shaft, outer sleeve are coaxial with the tubular shaft three.Motor case is fixed on the adjacent outer sleeve end, the outer sleeve head end is provided with inlet mouth, and tubular shaft is positioned at outer sleeve, and its head end and motor shaft link and be provided with air intlet, tail end stretches out outer sleeve, rubber-supporting bearing and propeller are contained in the tail end of tubular shaft successively, and when using this device, the two contacts with water, with the water lubricating rubber bearing, the tubular shaft head end is equipped with fan blade, and this fan blade is between inlet mouth and air intlet, in order that accelerate intake velocity.Tubular shaft can adopt shaft coupling with connecting of motor shaft, and rotates the influence of amplitude to motor itself in order to alleviate tubular shaft, is provided with bearing on the tubular shaft between inlet mouth and shaft coupling.The fixed form of fan blade on tubular shaft can adopt screw attachment.
Oxygenating machine with said structure, owing to add fan blade, enter the air intlet of tubular shaft after feasible air from the outer sleeve inlet mouth quickens, the air that causes entry has at last promoted the dissolving of oxygen in water from still all raisings greatly of the residence time water of bubbles volume.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model fan blade synoptic diagram.
The utility model is elaborated with embodiment below with reference to accompanying drawing.
As shown in Figure 1, motor (1) shell is screwed on the end of adjacent outer sleeve (11), outer sleeve is provided with inlet mouth (7), tubular shaft is positioned at outer sleeve, for the convenience on processing, tubular shaft is made of three parts, be coupling sleeve (4), spindle nose (13) and between the two and with the two open tube (12) with thread connection, the tubular shaft head end links with screw and motor shaft by shaft coupling, this shaft coupling is made up of sheet rubber (3) and coupling sleeve (2), the tubular shaft head end is provided with air intlet (10), bearing (5) is installed between shaft coupling and inlet mouth, the front end of bearing is with air guide ring (6), enter open tube in order to air from air intlet, between inlet mouth and air intlet, with screw (8) fan blade (9) is fixed on the open tube, the tail end of tubular shaft stretches out outer sleeve, rubber-supporting bearing (14) is contained in spindle nose successively with propeller (15), and load onto divergent nozzle (16) at the end of spindle nose, axial displacement with the restriction propeller, obviously, because the cause that fan blade is installed, the diameter of outer sleeve head end is corresponding bigger than other position.Be used for the purification of fish farming water body in view of the utility model more, when propeller (15) forms the vacuum zone in water, often easily that body is less fry sucks the vacuum zone and causes death, so fixing cone-shaped hood (17) at outer sleeve (11) tail end, simultaneously, for the unlikely formation that influences the vacuum zone, the taper cover is made netted.
When stating aerating machine in the use, aerating machine can be placed on the support of being made up of floating block, and as required, make itself and horizontal plane angled (15 °～30 °) tilt to stretch in the water.
Claims (4)
1, a kind of oxygenating machine that is used for gas-vapor mix, its member comprises motor (1), outer sleeve (11), tubular shaft, propeller (15) and rubber-supporting bearing (14) at least, motor case is fixed on the adjacent outer sleeve end, the outer sleeve head end is provided with inlet mouth (7), tubular shaft is positioned at outer sleeve, its head end and motor shaft link and are provided with air intlet (10), tail end stretches out outer sleeve, rubber-supporting bearing and propeller are contained on the tubular shaft tail end successively, it is characterized in that the tubular shaft head end is equipped with fan blade (9), this fan blade is between inlet mouth and air intlet.
