Technical Field

The invention relates to the technical field of water treatment equipment, in particular to a telescopic aeration filter head.

Background

Aeration is a means of bringing air into strong contact with water, and is aimed at dissolving oxygen in the air in water or expelling unnecessary gases and volatile substances in the water into the air. In other words, it is a means of facilitating mass exchange between gas and liquid. It also has other important functions such as mixing and stirring. According to the theory of mass transfer and diffusion, oxygen in air is transferred into water through aeration, and the oxygen is transferred from a gas phase to a liquid phase through mass transfer, but the circular aeration head is fixed, so that blockage is easy to occur, and the gas distribution is not uniform.

Disclosure of Invention

The invention aims to provide an aeration filter head which has uniform aeration and can perform intermittent aeration and prevent the filter head from being blocked.

In order to achieve the purpose, the invention adopts the following scheme: the utility model provides a telescopic aeration filter, includes the filter body, the filter body is the telescopic body, the inlet end is equipped with the separation mechanism of control air admission on the body, and during the air admission filter, promote separation mechanism makes the body straighten in the air admission body, and when not supplying air, separation mechanism plugs up the body inlet end and makes the body shrink, is curvy shape during the body shrink, the middle part of body is provided with the aeration hole to the even interval of afterbody.

Furthermore, separation mechanism is the choke hemisphere that sets up at the inlet end, choke hemisphere is including establishing two hemispherical blades at body upper inner wall and lower inner wall, and when the air got into, made choke hemisphere rotate, and partial air gets into in the body, accomplished the aeration, when air blows choke hemisphere and becomes closed pipeline state, the body shrink, so intermittent type formula circulation.

Furthermore, the aeration holes are arranged in a ladder shape from small to large along the middle part to the tail part of the pipe body, so that the aeration at all positions of the water body is uniform.

Further, the body is the flexible plastics body of telescopic, be the disc mosquito-repellent incense shape when the body contracts to satisfy the disturbance to the water at the continuous in-process that straightens and contract of body.

Has the advantages that: the invention aerates the water body in the process of straightening and contracting the filter head, solves the intermittent aeration problem, and simultaneously plays a role in disturbing the water body and prevents the aeration port from being blocked.

Detailed Description

The invention will be described in further detail below with reference to the figures and specific embodiments.

Referring to fig. 1, this embodiment provides a telescopic aeration filter, including the filter body, the filter body is telescopic body 1, and the inlet end is equipped with the separation mechanism of control air admission on the body 1, and separation mechanism is for setting up the choke hemisphere 2 at the inlet end, and the middle part of body 1 is to the even aeration hole 3 that is provided with of afterbody interval, and aeration hole 3 is the notch cuttype setting from small to big along body 1 middle part to afterbody.

When air enters the aeration filter head, the air passes through the choke hemisphere 2 recently, the choke hemisphere 2 rotates under the action of air flow pushing, in the rotating process, because the choke hemisphere 2 is hemispherical, a part of air can be conveyed into the flexible resettable mosquito-repellent incense-shaped pipe body 1, the pipe body is made of PE materials, the pipe body 1 is filled with air and straightened, and the air flows out through the stepped aeration holes 3, so that the water body is aerated; when the air blows the choke hemisphere 2 to be in a closed pipeline state, the pipe body 1 contracts to be in a mosquito-repellent incense type state, the pipe body is straightened and stretched, the disturbance effect on a water body is achieved, the aeration port is prevented from being blocked, and the intermittent type circulation work is achieved.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
