Description
Technical field
The utility model relates to a kind of aerator of use in fish breeding, specifically a kind of syndeton of paddle aerator.
Background technology
Oxygen is the necessary gas of fishes and shrimps life existence, most fish can only draw the oxygen that is dissolved in the water, and every liters of water contains the oxygen more than 3 milligrams in water, fish and shrimp ability normal existence and growth, in the water during anoxic, the water quality corruption, fish and shrimp expiratory dyspnea, anorexia, if every liter of oxygen content is less than the 0.5-1 milligram in the water, fishes and shrimps life will be on the hazard, and will cause " fish kill ", and " floating head " and death by suffocation.
The paddle aerator of various models though its profile and size are different, substantially all is made up of motor, decelerator, support bar assembly, impeller, ball float five parts.As shown in Figure 1.Among Fig. 1: 1, motor, 2, reduction box, 3, the support bar assembly, 4, ball float, 5, impeller.
During work, after paddle aerator slows down by reduction box 2 with electromotor, drives a big impeller rotation and stir water body, produce spray, and by the centrifugal force of rotation generation, the upper strata water body is spread to periphery, lower floor's water body formation water body of filling a vacancy circulates up and down.After the higher superficial water of oxygen content enters bottom, can effectively improve the dissolved oxygen situation of bottom water body, the rapid mineralising of organic matter in the bed mud be decomposed, thereby reach the effect of improving water quality, very favourable to aquaculture and increasing both production and income.
The paddle aerator effective area is big, and oxygen transfer rate, dynamic efficiency all are better than other types, and low price, is domestic the most widely used in recent years a kind of.Have comprehensive functions such as the water of stirring, oxygenation, mixing, aeration during its operate as normal.These effects are finished in machine operation procedure simultaneously.After the start, impeller sucks up the oxygen deprivation water of its bottom, again to around push out, make stagnant water become running water.Under the strong agitation of impeller and blade, the water surface evokes the hydraulic jump and the spray, and formation can entrain into the water curtain of air, has not only enlarged the surface area of gas-liquid interface, and the two film attenuation between gas-liquid, and brings in constant renewal in, and has promoted the dissolution velocity of oxygen in the air.Also original pernicious gas in the water, desorb from water by aeration during stirring, enter in the air as hydrogen sulphide, ammonia, methane, sulphur dioxide etc.
Traditional paddle aerator strut mainly adopts the common steel tube electric welding to form, and has hidden danger of quality: (1) structure heaviness, the uniformity of a machine Third Mate strut is poor, interchangeability is not strong.(2) the processing technology complexity, to use the frock annex more, welding quality does not reach requirement; (3) not corrosion-resistant, badly influence the service behaviour and the service life of complete machine; Damage ball float when (4) working easily, cause bad chain reaction.
Summary of the invention
The purpose of this utility model is to design a kind of syndeton of paddle aerator, solves the deficiency of traditional paddle aerator strut.
According to the technical scheme that the utility model provides, the syndeton of paddle aerator comprises fittings body, ring set and strut, it is characterized in that: an end of described strut is connected with fittings body, and the other end of strut is connected with ring set.
Described fittings body is connected with reduction box, and described ring set is connected with ball float.The left end of described fittings body is the rectangular flange dish, and described rectangular flange dish is connected with described reduction box; In fittings body, be cast with through hole; The right-hand member of fittings body is a cylindrical body, and utilizes stainless steel bolt to be connected with strut on described cylindrical body; The axle center of described through hole and the axis of strut are on same straight line.
The right-hand member of described ring set is an annular through-hole, the axle center of described annular through-hole and the axis normal of strut; Described annular through-hole links to each other with described ball float; The left end of ring set is the cylindrical body of hollow, on the shell of described cylindrical body reinforcement is arranged, and two bolts hole that penetrate cylindrical body are arranged at the top of cylindrical body, and described ring set utilizes stainless steel bolt to penetrate cylindrical body to be connected with strut.
Described strut is the coating steel pipe of hollow, and the axle center of the axis of strut and fittings body and ring set is on same straight line.Described fittings body is zinc-plated fine steel casting.The connecting hole of described ball float neck is cast with fillet.
It is excessive to the culture fishery direction that China's fishery is in marine fishing, and special aquaculture area every year is developed to efficient intensive culture direction by extensive style with 25% speed increase, and this has just determined that fishery machinery will be with bigger speed development.Paddle aerator is to be fit to the essential product that the intensive culture direction develops, ten thousand of annual requirement 15-20.Therefore there is huge development space in this product.
Analyze from raiser (or plant), one by 2000 yuan of calculating, the life security in the time of can guaranteeing 10～20 mu of fishing pond fish class anoxics.Generally be no more than 400 kilograms according to measuring and calculating, and use aerator, can reach 1200 kilograms/mu without the aerator per mu yield.Its economic benefit is obviously different, and does not use aerator, in case the fish anoxic will cause whole fish pond all to turn over the pool, and fishes and shrimps death, its loss a bite pool reaches more than ten ten thousand yuan, so buy on a bite pool, and an aerator is certain concerning the raiser to be calculated.Facts have proved that aerator is to improve fish crop, increases the indispensable fishery equipment of raiser's economic benefit.
The utility model has the advantages that: because when normal the use, the most of body except that motor is immersed in the water, easily corrosion.Particularly evident in mariculture.Nonmetallic materials and resistant material are adopted in the position that contacts with water, not only can alleviate weight, the reduction power attenuation of whole machine, and Corrosion Protection can increase substantially.The quality of the support bar of paddle aerator and two ends joint performance is to improve the aerator critical component in service life, in case damage, body work is tilted, even causes major accident such as heavy machine.
