Abstract
The utility model provides a novel oxygen increasing machine which is characterized in that a motor transmission shaft doesn't pass a speed reducing mechanism and is directly provided with a screw propeller or a device having the same or the similar function as a screw propeller, double layers of impeller wheels with hollow cavities are sheathed on the transmission shaft, and reversal blades and negative pressure air inlet pipes are distributed uniformly on the impeller wheels. The utility model with the advantages of small size, light weight, low cost, low noise, high efficiency, and favorable effect of oxygen increase can replace existing impeller wheel type oxygen increasing machines and can be widely used in various water areas for cultivation.
Description
The utility model relates to a kind of mechanical enhancement machine that floats on water surface for aquaculture.
Aerator is the effective means that improves the material culture survival rate and increase production significantly in the limited breed waters.In various aerators, the oxygen transfer efficiency of paddle aerator is the highest, therefore also uses the most general (referring to " principle of aerator and selection ", " agricultural machinery popularization " second phase in 1987).But, in order to satisfy the requirement of oxygenation effect and power consumption, reducing gear is housed all on all paddle aerators, and uses reducing gear can bring following problem:
1. reducing gear or complex structure, the machining accuracy height costs an arm and a leg; Volume is big, heaviness, and transmission efficiency is low, and the life-span is short.
2. the vibration that produces when reducing gear is worked and the growth of influence of noise material culture.
3. reducing gear is fragile, and maintenance difficult delays use.
The purpose of this utility model just provides a kind of novel aerator, propeller paddle aerator.It removes any type of reducing gear fully, thereby, can fundamentally overcome and fall the drawback that the use reducing gear brings, can make again simultaneously that it reaches that volume is little, in light weight, cost is low, uses just, maintenance easily, oxygen transfer efficiency improves or says the purpose that does not reduce at least.
The purpose of this utility model is achieved in that drive axle of motor is gone impeller without reducing gear in the aerator, but directly installs propeller or the function device identical or close with propeller, suit double-layer cavity impeller on power transmission shaft.Be evenly equipped with break-in blade and negative pressure inlet pipe in the double-layer cavity impeller.When motor drove the propeller rotation by power transmission shaft, lower floor's oxygen deprivation water was raised up, rushes at the break-in blade in the double-layer cavity impeller, because the active force of water and the guide effect of break-in blade make the double-layer cavity impeller do directed the rotation.Simultaneously, because the powerful water lift effect of propeller and the negative pressure of its generation, strengthened the circulation of lower floor's oxygen deprivation water and upper strata heavy-oxygen-enriched water, having enlarged the fresh air of going into through the negative pressure inlet pipe bit contacts with the gas-liquid two-phase of lower floor oxygen deprivation water, strengthened the dissolved oxygen effect, or said and can not reduce former vane type oxygenation effect at least.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the mansion view of double-layer cavity impeller of the present utility model.
Motor (3) is placed on the supporting seat (4), and propeller (6) is installed in the lower end of its power transmission shaft (5), installs the device identical or close with the propeller function, also can finish its identical effect as water pump vane etc.The double-layer cavity impeller (7) of umbrella is sleeved on the power transmission shaft (5), and it can act on relative motion with it.
By the operation principle of impeller as can be known, the work of the top of the blade of falling the umbrella shape is the most effective, and the more approaching top of falling the umbrella shape then efficient is low more.The utility model is managed based on this, and umbrella invalid inverted umbrella shaped impeller or the poor efficiency part backs down into hollow, again just in install and the hollow propeller that matches through size (6) herein.This just strengthened impeller this part stir water function, and increased the water lift function of propeller (6) newly.
Propeller (6) is stirred the water water lift function except strengthening and having increased, and also provides power for double-layer cavity impeller (7).Its principle is: after water is mentioned by the rotation of propeller (6) brute force, pour in the cavity of double-layer cavity impeller (7), and rush at and be positioned at the break-in blade (8) that delivery port (11) is located, the guide effect of impact force of water flow and break-in blade (8) makes double-layer cavity impeller (7) rotary work.
The negative pressure that propeller (6) high speed rotary produces, make fresh air pierce in the water rapidly through negative pressure inlet pipe (9), form various bubbles, pulverize when propeller (6) high speed rotary again and break up, the oxygen deprivation water that makes it to elevate with lower floor is able to fine mixing and contacts; Then, through the outer rim delivery port (11) of double-layer cavity impeller (7) outwards throw away constantly to around overflow and open, produce hydraulic jump and advection, further strengthened the gas-liquid two-phase contact.When double-layer cavity impeller (7) rotates, stir water that wiper blade (10) also stirs its below to around get rid of, kept the task performance of original paddle aerator.Around these two kinds of current constantly rush at, strengthen the circulation of deep layer oxygen deprivation water and top layer heavy-oxygen-enriched water, enlarged the contact-making surface of gas-liquid two-phase, improved the dissolved oxygen effect.In addition, because strong agitation and this pair of circulating water flow of propeller (6) make the new-type oxygen-increasing machine that certain aeration effect also be arranged.
The utility model is owing to removed or complicated, or heavy reducing gear, and therefore simple in structure, cost reduces noise and reduces, the transmission efficiency height, and maintenance is convenient; The weight that need not to carry reducing gear owing to floating drum (1) also can make it to reduce volume, thereby machine volume, weight are all greatly reduced again; Simultaneously, oxygenation effect also has raising.Therefore, it can replace existing paddle aerator fully, is widely used in all kinds of water surfaces for aquaculture.It also can be used in the processing of industrial wastewater; After the miniaturization, also can be used for culturing among the means of transport of being.
Embodiment of the present utility model is provided by Fig. 1 and Fig. 2, and detail is as follows: have three floating drums (1) supporting aerator (2), make it to float on water surface for aquaculture.Motor (3) is installed on the supporting seat (4).Power transmission shaft (5) passes through from supporting seat (4) center, and propeller (6) is installed in its lower end, and its stage casing is with routine umbrella shape double-layer cavity impeller (7).The top end of falling the umbrella shape of double-layer cavity impeller (7) is hollow, and the size of hollow drive matches with the external diameter size of the propeller that just is in this position.In the cavity of double-layer cavity impeller (7), be evenly equipped with 12～48 break-in blades (8) according to different the requirement, its position is installed in its outer rim delivery port (11) and locates.It is the heart with power transmission shaft (5), diameter is a bit larger tham on the circumference of propeller (6), is evenly equipped with four the negative pressure inlet pipes (9) parallel with power transmission shaft (5).And on its bottom of falling umbrella shape umbrella frame direction, be evenly equipped with 6～12 according to different requirements and stir wiper blade (10).
The material that the utility model embodiment uses is a ferrous metal, and obviously, according to different needs, it also can use aluminium alloy, engineering plastics or their combination.
