Description

Technical Field

[0001] This utility model relates to the field of jet ejector technology, specifically to a gas-water mixing jet ejector. Background Technology

[0002] In aquaculture, oxygenation technology is one of the key technologies. The dissolved oxygen content directly affects the stocking density and growth rate of fish. When the dissolved oxygen is insufficient, it will cause anaerobic decomposition of organic matter, ammonia nitrogen and other fish excrement in the water, producing toxic substances and causing a large number of fish to become infected and die. At present, the main method is to supplement the aquaculture water with water with high dissolved oxygen content through mechanical equipment. Existing oxygenation devices often use spraying devices such as jet sprayers.

[0003] An ejector, also known as a water jet ejector, is designed to mix gas and water and then spray the mixture outwards to increase the gas content in the water. Most existing ejectors are simple three-way shaped tubes. When oxygen and water flow combine, the solubility of oxygen in the water is limited, resulting in insufficient dissolved oxygen and inefficient utilization of oxygen. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a gas-water mixing jet injector. The technical solution adopted is that two jet heads are fixedly connected, each with a jet hole at its front end and an air inlet at its rear end. An air inlet pipe is fixedly connected to the rear end of each jet head, and an air guide groove is formed between the air inlet pipe and the jet head. The air inlet pipe communicates with the inner cavity of the jet head through the air guide groove and the air inlet. Gas enters from the air inlet pipe and flows into the two jet heads through the air guide groove and the air inlet. A water inlet pipe is fixedly connected to the lower part of each jet head, and a water inlet is formed tangentially on the side wall of the jet head. The water inlet communicates with the inner cavity of the jet head through the water inlet. The water inlet is tangentially arranged with the inner cavity of the jet head, so that the water flowing into the inner cavity of the jet head can rotate. The rotating water creates a certain negative pressure in the inner cavity of the jet injector, which helps the gas to enter. Water entering through the inlet pipe flows into the inner cavity of the jet head through the inlet. Gas enters the inner cavity and mixes with the water to form bubbles. The water body rotates multiple times, cutting the bubbles into tiny bubbles, which are then ejected from the jet hole with the water flow. The tiny bubbles stay in the water longer than the large bubbles, thus achieving the purpose of increasing dissolved oxygen.

[0005] As a preferred embodiment of this utility model, the air inlet is funnel-shaped to facilitate the entry of airflow into the inner cavity of the jet head, and the jet holes on the same jet head are coaxial with the air inlet.

[0006] As a preferred embodiment of this utility model, the air inlet pipe and the water inlet pipe are perpendicular to each other and both have internal threads on their inner sidewalls, which facilitates connection to external pipelines.

[0007] The beneficial effects of this invention are as follows: This invention designs two jet heads as gas-liquid mixing chambers. The air inlet pipe and water inlet pipe are arranged perpendicularly to each other and connected to the jet heads. The airflow enters through the air inlet pipe and then passes through the air guide groove and air inlet hole into the inner chambers of the two jet heads respectively. The water inlet is tangentially arranged to the inner chamber of the jet head, allowing the water flowing into the inner chamber to rotate. The rotating water creates a certain negative pressure in the inner chamber of the jet injector, which facilitates gas entry. The gas enters the inner chamber and mixes with the water to form bubbles. The repeated rotation of the water breaks the bubbles into tiny bubbles, which are then ejected from the jet holes with the water flow. These tiny bubbles stay in the water longer than larger bubbles, thus improving the gas-water mixing effect. This device has a simple structure, is easy to manufacture, convenient to use, and not easily damaged. Attached Figure Description

[0012] Example 1

[0013] like Figures 1 to 3As shown, this utility model discloses a gas-water mixing jet injector, consisting of two jet heads 1 fixedly connected, each with a jet hole 101 at its front end and an air inlet 102 at its rear end. The air inlet 102 is funnel-shaped to facilitate the entry of airflow into the inner cavity of the jet head 1. The jet holes 101 and air inlets 102 on the same jet head 1 are coaxial. An air inlet pipe 2 is fixedly connected to the rear end of the jet head 1. An air guide groove 4 is formed between the air inlet pipe 2 and the jet head 1. The air inlet pipe 2 communicates with the inner cavity of the jet head 1 through the air guide groove 4 and the air inlet 102. Gas enters from the air inlet pipe 2 and flows into the two jet heads 1 through the air guide groove 4 and the air inlet 102. The lower part of the jet head 1 is fixedly connected to a water inlet pipe 3. A water inlet 5 is tangentially opened on the side wall of the jet head 1. The water inlet pipe 3 communicates with the inner cavity of the jet head 1 through the water inlet 5. The water inlet 5 is tangentially arranged with the inner cavity of the jet head 1, allowing the water flowing into the inner cavity of the jet head 1 to rotate. The rotating water creates a certain negative pressure in the inner cavity of the jet nozzle, which facilitates the entry of gas. Water entering from the water inlet pipe 3 enters the inner cavity of the jet head 1 through the water inlet 5. Gas enters the inner cavity and mixes with the water to form bubbles. The water rotates multiple times, cutting the bubbles into tiny bubbles, which are then ejected from the jet hole 101 with the water flow. The tiny bubbles stay in the water longer than large bubbles, thereby increasing dissolved oxygen. The air inlet pipe 2 is perpendicular to the axis of the water inlet pipe 3, allowing the incoming water and air flow to collide within the inner cavity of the jet head 1, improving the mixing effect. Both the air inlet pipe 2 and the water inlet pipe 3 have internal threads on their inner side walls for easy connection to external pipelines.
