Pneumatic rotary arm type aerator

Abstract

The invention discloses a pneumatic rotary arm type aerator. The pneumatic rotary arm type aerator comprises a fan, a rotating mechanism and an oxygen exposure device which are connected sequentially, wherein the rotating mechanism comprises an inner pipe, a bearing sleeved on the inner pipe and an outer pipe sleeved on the bearing; the upper end of the inner pipe or the upper end of the outer pipe is connected with the fan through a pipeline; the lower outer wall of the inner pipe or the lower outer wall of the outer pipe is provided with a rotary arm which is extended outwards; the oxygen exposure device is arranged on the rotary arm; and a guide plate is fixedly arranged on the upper part of the oxygen exposure device. The device uses air pressure as driving force, so that the oxygen exposure device is rotated; and the structure is simple, and oxygen dissolving time and oxygen supply regions of air bubbles in water bodies are increased.

Description

technical field [0001] The invention relates to an aeration device applied in the field of aquatic products or water purification, in particular to a three-dimensional water body exchange pneumatic microporous aeration aeration machine. Background technique [0002] Microporous aeration and oxygenation is a new type of water oxygenation equipment that has emerged in recent years. It is mainly composed of fans, ventilation main pipes, hoses, aeration pipes, and brackets. It is laid on the bottom of the pond: 1. Through aeration, the Second, increase the contact area between air and water by rising air bubbles, and increase the dissolved oxygen in the water; third, increase the dissolved oxygen in the water, especially increase the dissolved oxygen in the lower water body, so that the dissolved oxygen in the entire water body Evenly distributed in the medium to ensure clean and clear water. It can also effectively solve the problem of increasing oxygen in high-density, indust...

AI Technical Summary

Problems solved by technology

For example: 1. To lay a long oxygen supply pipeline above and below the water, professionals need to install it on site, and the cost is relatively high, especially for larger ponds; 2. The installed machines and pipelines are fixed. It is very difficult to fish or need to move the location, which brings inconvenience to fishery production; 3. When repairing equipment such as pipeline damage, joint leakage, and replacement of aeration discs during use, professional installers are required to provide door-to-door service. It is labor-intensive and time-consuming; 4. The microporous aeration and aeration machine is fixed at a certain place on the bottom of the pool. When the air bubbles generated by the aeration tube penetrate into the water body in a vertical form, the buoyancy is relatively large, resulting in the melting time of oxygen in the water body. Shorter, due to fixed defects, it is difficult to push the air and water to a wider range, and it is also impossible to realize the large-scale water exchange between the upper and lower layers of the pond and the circulation of the water in the dead corner of the pond
