Description

A device for increasing oxygen and raising water

technical field

The utility model relates to an aeration device for aquaculture, sewage treatment and lakes.

Background technique

In the process of artificial aquaculture, in order to increase the output density of a single water surface, it is necessary to install aeration equipment in the aquaculture waters.

At present, the commonly used aeration equipment is waterwheel aerator, impeller aerator, water spray aerator, etc., and the oxygenation equipment is used to bring oxygen into the water. However, these current devices have low efficiency, high energy consumption, high cost, and hidden safety hazards, which are not conducive to popularization and application.

Chinese patent application number 02239678.0 provides a microporous artificial aquaculture aeration device, which is connected to an air duct by an exhaust device, such as an air compressor or a high-pressure blower outlet, and the other end of the air duct is connected to a micro Hole oxygenation tube; one end of the oxygenation tube is closed, and the tube wall is provided with a hollow tube with a number of tiny penetrating elastic channels; the oxygenation tube is axially fixed to a floating tube, and the floating tube is impermeable Lightweight rigid hollow tube; fixed weight is hung on the floating tube along the axial direction of the floating tube, and the heavy object is an object with a density greater than water.

There is an obvious defect in the above-mentioned patents and the current commonly used equipment, all of which are surface oxygenation, and the flow of water is only up and down, and the flow volume is small, so it is difficult to achieve the purpose of comprehensive aeration.

Utility model content

The purpose of this utility model is to provide an oxygen increasing and water lifting device to overcome the above-mentioned defects in the prior art.

The oxygen increasing and water lifting device of the present utility model comprises:

A barrel body closed all around, the top surface of the barrel body is an arc-shaped deflector, one side of the arc-shaped deflector is connected to the top corner of the barrel body, and the other side is inclined downward to the The body wall of the barrel is connected;

The water outlet provided on the upper part of the barrel, where the curved deflector connects with the top corner of the barrel;

a water inlet provided at the bottom of the barrel;

an air inlet provided at the lower part of the barrel;

The aerator is arranged in the lower part of the barrel and communicated with the air inlet.

The utility model has the advantages of simple structure and convenient operation, is suitable for various water body environments, and has the functions of increasing oxygen and lifting the bottom water to the water surface at the same time, and has great practical value.

Description of drawings

Fig. 1 is a schematic diagram of the structure of the oxygen increasing and water lifting device.

Fig. 2 is a schematic diagram of the three-dimensional structure of the oxygen increasing and water lifting device.

Detailed ways

Referring to Fig. 1 and Fig. 2, the oxygen increasing and water lifting device of the present utility model comprise:

A barrel body 1 closed all around, the top surface of the barrel body is an arc-shaped deflector 2, one side of the arc-shaped deflector 2 is connected to the top corner of the barrel body 1, and the other side is connected to the downward Obliquely connected with the body wall of the barrel body 1;

The water outlet 3 is provided at the upper part of the barrel body 1 where the curved deflector 2 is connected to the top corner of the barrel body 1;

The water inlet 4 provided at the bottom of the barrel;

The air inlet 5 provided at the lower part of the barrel;

The aerator 6 is arranged at the lower part of the barrel and communicates with the air inlet 5 .

The aerator 6 is a gas distributor provided with gas distribution holes, and the gas distribution holes are arranged on the upper side of the aerator 6;

Preferably, the barrel body 1 has a rectangular longitudinal section and a rectangular or circular cross section.

The principle of the utility model is as follows:

Referring to Figures 1 and 2, the utility model is placed in the water body so that the water surface 8 is at the top 1/3 of the water surface on the deflector, and the air is sent into the aerator 6 by a blower fan through the air supply pipe, and the air is blown out from the aerator. The tiny bubbles in the air continue to rise, and drive the water to move upwards in the barrel, forming a water column in which air and water mix and flow. Through the deflector 2, the water body moves in one direction, not only the oxygen in the air is well dissolved, but also The water at the bottom is brought to the upper part of the water body, and flows out in one direction from the water outlet.
