Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 3, in an embodiment of the present invention, an aeration tank for sewage treatment is disclosed, including a tank body 100 with an open top, an aeration structure 200 is disposed inside the tank body 100, the aeration structure 200 includes a first pipe 210 disposed in an inclined manner, and a second pipe 220 communicated with a higher inclined end of the first pipe 210, the second pipe 220 extends upward and is communicated with an air outlet of an air pump 300 outside the tank body 100, a third pipe 230 is communicated with a middle top of the first pipe 210, the third pipe 230 extends vertically upward, outer walls of the first pipe 210 and the third pipe 230 are both provided with a bubbling member 400, and the air pump 300 supplies air towards the inside of the aeration structure 200 and generates a large amount of air bubbles through the bubbling member 400; the bottom of the side wall of the tank body 100 is communicated with a discharge pipe 110, and the discharge pipe 110 is provided with a switch valve.

The aeration tank for sewage treatment is novel in structure, the aeration structure comprises the first pipe body, the second pipe body, the third pipe body and the bubbling pieces arranged on the first pipe body and the third pipe body, when the air pump supplies air to the interior of the aeration structure, a large amount of bubbles can be generated through the bubbling pieces, liquid can be mixed during bubbling, contact between the liquid in the aeration structure and the air is accelerated, and accordingly aeration efficiency and effect are effectively improved; first body sets up for the slope, can make the inside liquid of getting into aeration structure also discharge smoothly, prevents that liquid from being detained in aeration structure inside.

Further, a plurality of fourth tubes 240 are fixedly and communicatively arranged on the outer walls of the first tube 210 and the third tube 230, threads are arranged on the inner wall of the fourth tubes 240, and the bubbling member 400 is installed at the fourth tubes 240 in a threaded connection manner; this structural design can make things convenient for the installation cooperation of bubbling piece and fourth body, and the dismouting of being convenient for is overhauld or is replaced.

Further, the bottom of the inclined lower end of the first tube 210 is communicated with a fifth tube 250, the structure of the fifth tube 250 is the same as that of the fourth tube 240, and the bubbling member 400 is installed inside the fifth tube 250; this structural design can ensure that the liquid that gets into aeration structure inside all can discharge completely at last, further prevents that liquid from detaining inside.

Further, the bubbling piece 400 comprises a sleeve 410 with one closed end, the outer wall of the sleeve 410 is provided with threads, the closed end face of the sleeve 410 is provided with a plurality of first exhaust holes 420, the first exhaust holes 420 are distributed in a circumferential array around the axis of the sleeve 410, and the middle part of the closed end face of the sleeve 410 is concavely provided with a first prismatic groove 430; the inner wall of the other end of the sleeve 410 is provided with threads, the threads are connected with a limiting block 440, a plurality of second exhaust holes 450 are formed in the limiting block 440, the second exhaust holes 450 are distributed in a circumferential array around the center of the limiting block 440, and a second prism groove 460 is concavely formed in the middle of the bottom surface of the limiting block 440; a bubbled stone 470 is arranged in the sleeve 410, and the bubbled stone 470 is matched with the inner part of the sleeve 410; the structural design can facilitate the processing, production and assembly of the bubbling piece, and facilitate the replacement of the internal bubble stone; it should be noted that the sleeve is an integrally formed structure made of metal material or plastic, and the material of the limiting block is consistent with that of the sleeve so as to be matched with the sleeve in a threaded connection manner.

Furthermore, the first prism groove 430 extends through the sleeve 410, and the second prism groove 460 extends through the two end faces of the limiting block 440, so that the contact area between the bubbling stone and the outside can be further increased, and the bubbling amount can be increased.

Further, a check valve 260 is installed at the top end of the second tube 220 to prevent the liquid inside the tank body from flowing toward the air pump along the aeration structure.

Further, the inner wall of the bottom of the tank body 100 is obliquely arranged and is obliquely and downwardly inclined towards one side of the discharge pipe 110, so that the discharge of the internal liquid is facilitated.
