Abstract
The utility model discloses an oxygen enriched machine which belongs to the technical field of the oxygen enrichment of a fish pond. The utility model is characterized in that an oxygen enriched device whose gas and water flow channels are separated is adopted by the oxygen enriched machine, and a hollow propeller shaft communicated with atmospheric air is connected with the oxygen enriched device. The oxygen enriched machine is provided with the functions of water absorption, water pressing, water body agitation and vortex air extraction. The utility model has the advantages of simple structure, high efficiency, low cost, wide oxygen enriched range and little noise. The oxygen enriched machine is suitable for the oxygen enrichment of the fish pond and can also be used for sewage purification of an aeration tank.
Description
The utility model belongs to a kind of aerator of used for aquiculture, is mainly used in fish pond oxygenation, also can be used for the aeration basin sewage purification.
In the prior art with the utility model more approaching be impeller stirring-type mechanical enhancement and eddy current type bleeding technique, about eddy current type bleeding technique and facility thereof, can consult Soviet Union's " method and apparatus of waters oxygenation ", version in 1978; Impeller stirring-type bleeding technique and facility can be consulted " fresh water fishery machinery " teaching material, and department of agricultural engineering of Hua Zhong Agriculture University compiles, in September, 1985, oil printed books.The oxygenation efficient of impeller stirring-type aerator is higher, and the oxygenation scope is bigger, but needs to be equipped with deceleration device with the reduction rotating speed, thereby complex structure, the volume heaviness, and noise is big, the cost height.Eddy current type aerator dynamic efficiency height, simple in structure, noise is little, and cost is low, but sphere of action is less.
The purpose of this utility model is to overcome existing technical deficiency, develop a kind of simple in structure, dynamic efficiency height, noise are little, cost is low, the aerator of the novel used for aquiculture that particularly oxygenation scope is bigger, this machine not only is fit to the oxygenation to all kinds of fish ponds, and the purification of suitable aeration basin sewage.
The utility model is realized by following proposal: automatic aerator 6, this automatic aerator 6 that this aerator has motor 1, shaft coupling 2, bearing block 3, support 4, buoyancy aid 5 and at least one gas, water flow passage separation link to each other with the Hollow Transmission Shafts 20 that an atmosphere communicates, and these Hollow Transmission Shafts 20 above waters and drive disk assembly have an air admission hole 10 at least.
Principle of the present utility model is, when needs are given the water body oxygenation in fish pond, starter motor makes automatic aerator 6 rotations, after automatic aerator 6 rotations, stir water body on the one hand, make water body form eddy current and suction air, the air that is sucked enters water body by flow channel 15, form bubble, the automatic aerator 6 through rotation is broken into countless minute bubbles again; On the other hand, the water that is filled in water flow passage is thrown toward under action of centrifugal force around the automatic aerator with broken minute bubbles and mixes, formed like this water under high pressure-gas mixed liquor just is diffused in the water body rapidly and goes, thereby has improved the oxygen content of water body and enlarged the oxygenation scope.Moreover the suction of the import department of water flow passage self constantly sucks the source, water source of lower floor, upper and lower water body is constantly circulated, thereby it is even to reach the dissolved oxygen vertical distribution.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1. be the overall structure schematic diagram of the utility model and one of them embodiment.
Fig. 2. be the Hollow Transmission Shafts structural representation of the utility model and one of them embodiment.
Fig. 3. be the automatic aerator structure longitudinal section of the utility model and one of them embodiment.
Fig. 4. be automatic aerator structure vertical view.
Fig. 5: be Fig. 3 A-A cross-sectional view.
Shown in accompanying drawing 1: the utility model partly is made up of motor 1, shaft coupling 2, bearing block 3, support 4, buoyancy aid 5, automatic aerator 6 and Hollow Transmission Shafts 20 etc.
Shown in accompanying drawing 2: Hollow Transmission Shafts 20 partly is made up of upper flange 7, quill shaft 8 and lower flange 9 etc., Hollow Transmission Shafts 20 parts place the appropriate location of fish pond, another part surfaces, and has an air admission hole that communicates with atmosphere 10 on the above water of this power transmission shaft 20 and the drive disk assembly thereof at least.
Shown in accompanying drawing 3,4 and 5, automatic aerator 6 is by back shroud 13, front shroud 14, parts such as blade 17, dividing plate 18 and inlet strainer 19 are formed, between described forward and backward two cover plates 14,13, some equally distributed blades 17 are arranged, they constitute gas, the water flow passage 15,16 of separating, and described gas, water flow passage are alternately.Flow channel 15 has the dividing plate 18 that separates with water inlet duct 12, has an air inlet duct 11 that communicates with flow channel 15 on the back shroud 13 at least, and this duct 11 is communicated with described Hollow Transmission Shafts 20.Back shroud 13 and lower flange 9 formed air chambers (seeing shown in the accompanying drawing 1), after entering air in the quill shaft 8 and arriving air chamber, arrives flow channels 15 through air inlet duct 11 again; Enter the water inlet duct 12 ingoing stream roads 16 of the water of inlet strainer 19 by front shroud 14.
In order to improve the oxygenation efficient and the active area of this machine, the present invention is except that adopting dividing plate 18 " stifled road " to make gas, the moisture road, also take suitably to dwindle the diameter diameter of front shroud 14 (promptly less than) of back shroud 13, the port of export of blade 17 is exposed outside the back shroud 13.Its effect is to smash the bubble that is entered water body by flow channel 15, and then is decomposed into countless minute bubbles, thereby improves the rate of dissolution of oxygen in the air.Obviously, for reaching this purpose, also can make front shroud 14 diameter less than the diameter of back shroud 13, the port of export of described blade 17 exposes outside the front shroud 14; Can also be designed to the forward and backward cover plate of equal diameters, and the port of export of blade 17 is exposed outside the forward and backward cover plate 14,13.
Embodiment:
