Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a gas-liquid mixing drainage pipe. Background Technology

[0002] Since the drain outlet of a fish tank or pond is usually under negative pressure, the amount of air intake is insufficient under natural aeration conditions, resulting in uneven water flow and uneven air mixing in the water. At the same time, the large changes in flow velocity during the drainage process can easily generate significant noise. Therefore, it is necessary to design a device that ensures that the water flowing through the drain outlet mixes evenly with the air. This would not only make the water flow smoother and reduce noise, but also increase the amount of air mixed in, achieving better oxygenation and protein skimming functions.

[0003] Based on this, the applicant proposed a gas-liquid mixing drainage pipe to solve the above technical problems. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a gas-liquid mixing drainage pipe to solve the aforementioned technical problems.

[0005] This utility model is solved by the following technical solution:

[0006] A gas-liquid mixing drainage pipe includes a pipe body, one end of which is an air inlet and the other end is a water outlet. The pipe body is also provided with a water inlet located at the lower end of the air inlet. Air mixes with water through the air inlet and then flows out through the water outlet.

[0007] Preferably, the water inlet includes a through hole disposed on the side wall of the pipe body.

[0008] Preferably, the through holes are evenly distributed along the circumference of the side wall of the tube.

[0009] Preferably, the water inlet includes a through groove disposed at one end of the side wall of the pipe body.

[0010] Preferably, the through grooves are evenly distributed along the circumference of the side wall of the pipe body.

[0011] Preferably, a collar is slidably connected to the pipe body, and the collar slides to cover the water inlet, preventing water from flowing into the pipe body from the water inlet.

[0012] Preferably, the tube body is also provided with a connector.

[0013] Preferably, the connector is detachably and fixedly connected to the tube body.

[0014] Preferably, the connector is connected to the pipe body by a threaded connection, a snap-fit ​​connection, or a plug-in connection.

[0015] Preferably, the connector includes connector A, connector B, or connector C, wherein connector A is a constant diameter connector, connector B is an elbow connector, and connector C is a variable diameter connector.

[0016] The beneficial effects of this utility model are as follows: By providing through holes or grooves on the pipe body, during installation, the through holes or grooves are positioned below the liquid surface, while the upper end of the pipe body protrudes above the liquid surface. This allows for a more uniform mixing of water flowing in through the through holes or grooves with air mixed in from the upper end of the pipe body, resulting in a larger air mixing volume. This not only makes the water flow more uniform but also provides better oxygenation and protein separation functions, while reducing water flow noise. Furthermore, the inclusion of a collar allows users to adjust the size of the inlet according to the actual usage environment, thereby adjusting the gas-liquid ratio in the gas-liquid mixture. Finally, the inclusion of connectors meets the connection requirements of different pipe diameters and different outlet angles, making it more widely applicable. Attached Figure Description

[0028] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0029] like Figure 1 As shown, the present invention discloses a gas-liquid mixing drainage pipe, comprising a pipe body 1, one end of which is an air inlet and the other end is a water outlet. The pipe body 1 is also provided with a water inlet, which is located at the lower end of the air inlet. Air mixes with water through the air inlet and flows out through the water outlet. The water inlet includes a through hole 2 provided on the side wall of the pipe body 1, and the through hole 2 is uniformly arranged along the circumference of the side wall of the pipe body 1.

[0030] When in use, insert the lower end of tube 1 into the drain of the aquarium, with the through hole 2 submerged below the liquid surface and the upper end of tube 1 protruding above the liquid surface. At this time, water will flow into tube 1 through the through hole 2, while air will mix into the water flow from the upper opening of tube 1, making the gas-liquid mixture entering the drain more uniform and the flow smoother, while also reducing noise. The gas mixed in the water flow is more uniform and in greater quantity, resulting in better oxygenation and protein skimming functions.

[0031] The through holes 2 are evenly arranged around the circumference, and the water flow is divided into multiple streams. The air in the gaps between the multiple water streams is mixed in by the water flow. The air in the air inlet is continuously replenished into the gaps, so that the air can be continuously mixed into the water flow, forming a stable gas-liquid mixture at the water outlet. Example 2

[0032] like Figure 2 As shown, this utility model discloses a gas-liquid mixing drainage pipe, including a pipe body 1. One end of the pipe body 1 is an air inlet, and the other end is a water outlet. The pipe body 1 is also provided with a water inlet, which is located at the lower end of the air inlet. Air mixes with water through the air inlet and then flows out through the water outlet. The water inlet includes a through hole 2 provided on the side wall of the pipe body 1. The through hole 2 is evenly arranged along the circumference of the side wall of the pipe body 1. A collar 3 is slidably connected to the pipe body 1. After the collar 3 slides to cover the water inlet, it blocks the water from flowing into the pipe body 1 from the water inlet.

[0033] When in use, insert the lower end of tube 1 into the drain of the aquarium, with the through hole 2 submerged below the liquid surface and the upper end of tube 1 protruding above the liquid surface. At this time, water will flow into tube 1 through the through hole 2, while air will mix into the water flow from the upper opening of tube 1, making the gas-liquid mixture entering the drain more uniform and the flow smoother, while also reducing noise. The gas mixed in the water flow is more uniform and in greater quantity, resulting in better oxygenation and protein skimming functions. By sliding the collar set on tube 1, the size of the water inlet can be changed, making it convenient for users to adjust according to the actual environment. Example 3

[0034] like Figures 3 to 4 As shown, this utility model discloses a gas-liquid mixing drainage pipe, comprising a pipe body 1, one end of which is an air inlet and the other end is a water outlet. The pipe body 1 also has a water inlet located below the air inlet. Air mixes with water through the air inlet and flows out through the water outlet. The water inlet includes a through hole 2 on the side wall of the pipe body 1, the through hole 2 being evenly distributed along the circumference of the side wall of the pipe body 1. A collar 3 is slidably connected to the pipe body 1, the collar 3 slidingly covering the water inlet and preventing water from flowing into the pipe body 1 from the water inlet. The pipe body 1 also has a connector, which is detachably and fixedly connected to the pipe body 1. The connector is connected to the pipe body 1 by a threaded connection, a snap-fit ​​connection, or a plug-in connection. The connector includes a connector A4, which is a connecting pipe of equal diameter.

[0035] If the pipe body 1 and the drain outlet have the same diameter and cannot be directly connected, a connector A4 can be installed on the lower side of the pipe body 1. The connector A4 is a connector of the same diameter, with one end tightly connected to the lower side of the pipe body 1 and the other end tightly connected to the drain outlet pipe. Example 4

[0036] like Figures 5 to 6 As shown, this utility model discloses a gas-liquid mixing drainage pipe, comprising a pipe body 1, one end of which is an air inlet and the other end is a water outlet. The pipe body 1 also has a water inlet located below the air inlet. Air mixes with water through the air inlet and flows out through the water outlet. The water inlet includes a through hole 2 on the side wall of the pipe body 1, the through hole 2 being evenly distributed along the circumference of the side wall of the pipe body 1. A collar 3 is slidably connected to the pipe body 1, the collar 3 slidingly covering the water inlet and preventing water from flowing into the pipe body 1 from the water inlet. The pipe body 1 also has a connector, the connector being detachably and fixedly connected to the pipe body 1. The connector is connected to the pipe body 1 by a threaded connection, a snap-fit ​​connection, or a plug-in connection. The connector includes a connector B5, which is an elbow connector.

[0037] If the drain pipe is not vertically installed, connector B5 is required when connecting the pipe body 1 to it. Connector B5 is an elbow connector. The elbow connector with the corresponding angle can be selected according to the angle between the drain pipe and the pipe body 1. For example, in this embodiment, if the drain pipe is horizontally installed, then connector B5 is a 90° elbow connector. One end of it is tightly connected to the lower side of the pipe body 1, and the other end is tightly connected to the drain pipe. Example 5

[0038] like Figures 7 to 8 As shown, this utility model discloses a gas-liquid mixing drainage pipe, comprising a pipe body 1, one end of which is an air inlet and the other end is a water outlet. The pipe body 1 also has a water inlet located below the air inlet. Air mixes with water at the air inlet and flows out from the water outlet. The water inlet includes a through hole 2 on the side wall of the pipe body 1, the through hole 2 being evenly distributed along the circumference of the side wall of the pipe body 1. A collar 3 is slidably connected to the pipe body 1, the collar 3 slidingly covering the water inlet and preventing water from flowing into the pipe body 1 from the water inlet. The pipe body 1 also has a connector, which is detachably and fixedly connected to the pipe body 1. The connector is connected to the pipe body 1 by a threaded connection, a snap-fit ​​connection, or a plug-in connection. The connector includes a connector C6, which is a reducing connector.

[0039] If the pipe body 1 and the drain outlet have different diameters and cannot be directly connected, a connector C6 needs to be installed on the lower side of the pipe body 1. This connector is a reducing pipe, with one end having the same diameter as the pipe body 1 and the other end having the same diameter as the drain outlet pipe, thus achieving a tight connection between the two ends. Example 6

[0040] like Figure 9 As shown in the above embodiment, in a gas-liquid mixing drainage pipe of the present invention, the inlet can be replaced by a through hole 2 and a through groove 7 provided at one end of the side wall of the pipe body 1. The through groove 7 is uniformly arranged along the circumference of the side wall of the pipe body 1.

[0041] When in use, insert the end of the tube 1 with the through groove 7 into the drain of the aquarium. The through groove 7 is submerged below the liquid surface, while the other end of the tube 1 is exposed above the liquid surface. At this time, water will flow into the tube 1 from the through groove 7, and air will mix into the water flow from the upper opening of the tube 1. This makes the gas-liquid mixture entering the drain more uniform and the flow smoother, while also reducing noise. The gas mixed in the water flow is more uniform and in greater quantity, resulting in better oxygenation and protein skimming functions.
