A fish tank oxygenation silencer

Abstract

The invention belongs to the technical field of aquaculture, and in particular relates to a fish tank aeration muffler, which includes an exchange pipe, a connecting pipe and an exhaust pipe. The lower end of the connecting pipe is located in the exchange pipe, and the second connecting wall of the connecting pipe is higher than the second Connecting part, the inner diameter of the first connecting wall in the connecting pipe is larger than the inner diameter of the third connecting wall, the upper end surface of the second connecting wall is respectively connected with the first connecting wall and the third connecting wall to form a water injection cavity, and the inner side of the third connecting wall forms an air-filled cavity Through the upper end of the connecting pipe, gas and water can be injected through the water injection chamber and the inflatable chamber respectively, so that the gas inflated from the inflatable chamber is crushed and refined under the impact of the water flow, and the gas and liquid are separated through the channel formed by the inner wall of the first connecting part. Introduced into the exchange tube, the gas rises upward through the channel formed between the inner wall of the exchange tube and the outer wall of the barrier under the action of pressure, and is discharged through the exhaust pipe connected to the transition tube, which effectively increases the contact stroke between the air bubbles and water. Even better the gas is soluble in water.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an aeration muffler for fish tanks. Background technique [0002] In the field of aquaculture, it is necessary to use water pumps to replenish clean water and filter impurities in aquariums or breeding ponds. On the other hand, it is necessary to use electric air pumps to inject compressed air into the water to increase the gas content. Although this dual-pump working mode can complete water injection and oxygenation However, during the operation, the noise of machinery and water flow is large, the power consumption is large, the water consumption is large due to splashing of water, and the surrounding environment humidity is high. [0003] The silent fish tank water injection aerator in the prior art is simple in structure, easy to use, low in noise, has both water injection and oxygen increase performance, can complete the oxygen increase work while injecting wa...

Problems solved by technology

However, due to the lack of an independent distributor in the anechoic chamber, the dispersion effect of the water flow is not good, which affects the effect of oxygenation and noise reduction. At the same time, due to the unreasonable air hole setting, the air exchange in the anechoic chamber cannot be realized. After a long period of use, the anechoic chamber cannot be supplemented with fresh air, increasing the Oxygen effect needs to be improved
