Embodiment Construction

[0016] Such as figure 2 , an anti-clogging aeration nozzle, including a nozzle body provided with a plurality of aeration holes 11, each aeration hole is equipped with a valve core 21, all valve cores are located on the elastic member 20, and the elastic member is sealed and connected with the nozzle body, An air chamber 30 is formed, and the air chamber is connected with an air supply pipe 31 .

[0017] In practice, the aeration nozzle of the present invention is located in the water body in the river, the air supply pipe 31 is connected to the aerator, and the aerator can be installed on the river or on floating objects on the river. In the case of no aeration, the water pressure acts on the elastic member 20 to squeeze the air chamber 30, and the elastic member elastically deforms toward the inner side of the air chamber. Stomata 11, like this, the dirt in the water body can't enter aeration hole or air chamber. When aeration is required, the aerator supplies gas to the ...

Abstract

A disclosed anti-blocking aeration nozzle comprises a nozzle body provided with a plurality of aeration holes, a valve element is arranged in each aeration hole in a matched mode, all the valve elements are located on an elastic piece, the elastic piece is connected with the nozzle body in a sealed mode to form an air chamber, and the air chamber is connected with an air supply pipeline. Initially, water pressure acts on the elastic piece, and the valve elements block the aeration hole; and when aeration is needed, an aerator supplies air into the air chamber through the air supply pipeline, the pressure in the air chamber is increased, external water pressure is overcome, the air chamber expands, and the elastic piece drives the valve elements to open the aeration hole. According to the aeration nozzle disclosed by the invention, during aeration, gas in the gas chamber is aerated outwards, and dirt in a water body cannot enter the aeration holes or the gas chamber; and when aeration is stopped, under the action of water pressure, the aeration hole is blocked by the valve element, the air chamber is sealed, and dirt in water cannot enter the aeration hole or the air chamber. Therefore, the aeration nozzle disclosed by the invention has an anti-blocking function.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an aeration device. Background technique [0002] Aeration, the forced transfer of oxygen in the air to the liquid, the purpose is to obtain enough dissolved oxygen. In addition, aeration also has the purpose of preventing the suspension of the water body from sinking and strengthening the contact between the organic matter in the water body, microorganisms and dissolved oxygen. In order to ensure that the microorganisms in the water body can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. The aeration adopts an aeration nozzle, and a number of aeration holes are opened on the nozzle. Because the water body contains dirt, the aeration holes are easily blocked. Contents of the invention [0003] The technical problem solved by the present invention is to provide an anti-clogging aeration nozzle. [0...
