Pond aerator and application

Abstract

The invention discloses a pond aerator, and relates to a pool aerator and application thereof. The aerator solves the problems that the conventional aerator has high impeller resistance, is high in energy consumption, frequently beats fishes and shrimps to death, and can only pump shallow water to the air and has smaller covering surfaces and low oxygen supply effect, and a motor is easy to burn, so that the single-unit oxygen supply coverage area is improved, and the lower watt limit and the cost of an optional motor are reduced. The aerator basically consists of a motor (2), a reducer (3), a tubular fork-shaped water thrower (5), and fixing and connecting components, wherein the tubular fork-shaped water thrower (5) is arranged at the upper end of a vertical hollow round pipe (9), and is connected with a radial hollow round pipe (10). The aerator can throw water in a deeper layer to the air; and the thrown water is fully dispersed, water beads are fully distributed in the air and the coverage area is large, so that the water and the air are fully contacted to fulfill the aim of aeration. A novel variety is provided for pond aerators, the effectiveness of the aerators is improved, and effective guarantee is provided for increasing the density of aquaculture, safely producing and improving benefit.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, in particular to a pond oxygen feeder and its application. technical background [0002] Pond oxygen generator is an important equipment to ensure fishery production. At present, the pond oxygen generator is generally composed of a motor, a reducer, a water stirring part (generally an impeller), a fixing and a connecting part. The rotation of the motor drives the impeller through the reducer, and the blades stir up the shallow water. Due to the contact between the water and the air, the oxygen in the air is brought into the water to achieve the purpose of increasing oxygen. However, it has the following problems: 1. the existing oxygen feeder uses the impeller as a water stirring part. Because the resistance of the impeller is relatively large, the lower limit of the wattage of the motor used is relatively high, and the diameter of the water thrown out is only about 4 meters. The cov...

Problems solved by technology

However, it has the following problems: 1. the existing oxygen feeder uses the impeller as a water stirring part. Because the resistance of the impeller is relatively large, the lower limit of the wattage of the motor used is relatively high, and the diameter of the water thrown out is only about 4 meters. The coverage area is small, and the traditional pond oxygen generator can only pump shallow water into the air, which affects the oxygen supply effect, so it is necessary to start multiple oxygen generators to supply oxygen to the pond, resulting in a huge waste of materials and energy, and causing damage to the power grid. Great pressure, but also a heavy economic burden on farmers; ②The water thrown by the impeller is in the form of large flakes, not beads, so that the contact area between water and air is small, and the oxygen supply effect is poor; ③The traditional oxygen generator relies on the impeller Immersing in water and stirring the water will often kill fish and shrimp and cause economic losses; ④The large resistance of the impeller leads to a large starting current of the motor and prolonged starting time, often causing motor burnout accidents
