Problems solved by technology

[0003] However, the limitation of the air lift pump is that the head is too low, and the general water level lift height is only about a dozen centimeters to half a meter, and its application range is greatly restricted.

Embodiment 1

[0023] Embodiment one (nine-stage cascade air lift pump)

[0024] Such as figure 2 , Figure 4 As shown, the outer cavity 12 of this embodiment is divided into nine units arranged in a matrix (3×3 matrix) by a plurality of partitions 19, and nine airlift tubes 14 are connected in series to form a nine-stage cascade Air lift pump, the overall appearance is a square column to save space. Each unit is respectively provided with a stripping pipe 14 in the middle, and the communication mode between each unit and the stripping pipe 14 in each unit is a series connection; The water inlet pipe 11 is connected, and the first-stage airlift pipe 14 is connected with the unit where the second-stage airlift pipe 14 is located through the connecting pipe 15, and the second-stage airlift pipe 14 is connected with the third-stage airlift pipe 14 through the connecting pipe 15. The unit at place is connected, and the third stage air lift pipe 14 is downwards communicated with the unit at t...

Embodiment 2

[0025] Embodiment two (four-stage cascade air lift pump)

[0026] Such as Figure 5 As shown, the outer cavity 12 of this embodiment is divided into four linearly arranged units by a plurality of partitions 19, and four airlift tubes 14 are connected in series to form a four-stage cascaded airlift pump. Each unit is provided with an airlift pipe 14 in the middle, and the communication mode between each unit and the airlift pipe 14 in each unit is series; that is, the unit where the first stage airlift pipe 14 is located is connected to the water inlet pipe 11 Pass, the first-stage airlift pipe 14 is connected with the unit where the second-stage airlift pipe 14 is located through the connecting pipe 15, and the second-stage airlift pipe 14 is connected with the unit where the third-stage airlift pipe 14 is located through the connecting pipe 15 The third-stage airlift pipe 14 communicates with the unit where the fourth-stage airlift pipe 14 is located through the connecting p...

Abstract

The invention belongs to the field of aquaculture engineering, and specifically relates to a cascading gas stripping pump. An external chamber is internally divided into a plurality of units, wherein each unit is provided with a one-level gas stripping pipe. A lower end of each gas stripping pipe is provided with an aeration head. Each unit provided with a corresponding one-level gas stripping pipe communicates with an inner part of a corresponding upper-level gas stripping pipe through a communication pipe, wherein the one-level gas stripping pipe communicates with a corresponding lower-level unit through a connection pipe. A water feeding pipe and a water discharging pipe are mounted on the external chamber, wherein the water feeding pipe communicates with the unit where a first-level gas stripping pipe is, and the water discharging pipe communicates with an inner part of a final-level gas stripping pipe. A chamber lid is installed on the external chamber. A position, corresponding to each one-level gas stripping pipe in the external chamber, of the chamber lid and a position, corresponding to each unit, of the chamber lid are provided with vent holes, respectively. The first-level gas stripping pumps water through the water feeding pipe; water is elevated step by step through the one-level gas stripping pipes; and the elevated water is discharged through the water discharging pipe. Therefore, defects that a gas stripping pump in the prior art is relatively low in elevation height and limited in application range are overcome.

Description

technical field [0001] The invention belongs to the field of aquaculture engineering, in particular to a cascade air lift pump. Background technique [0002] In pond culture, seed cultivation, especially in factory culture production, it is often necessary to transport water bodies with small head and large flow. The traditional method is to use water pumps (such as axial flow pumps, submersible pumps, centrifugal pumps, etc.) to transport, but there are almost no water pumps on the market with a head lower than 1m. Ordinary water pumps not only have high energy consumption, low work efficiency, and inconvenient installation, management and operation; moreover, due to the large flow rate and fast flow rate of the water pump, breeding organisms can easily enter the pump body and be damaged, causing unnecessary losses. Airlift pumps have been used in industry for a long time, and have been widely used in aquaculture production in recent years. The air lift pump has the chara...
