As shown in fig. 1-3, a wing type sludge discharging device for sludge discharge comprises a sludge discharging pipe 2 and an air injection pipe 3 which are arranged at the lower part of a water treatment sludge settling tank 1, wherein the air injection pipe 3 is provided with an air injection hole 31 for injecting sludge at the bottom of the sludge settling tank, the sludge discharging pipe 2 is transversely suspended at the bottom of the sludge settling tank 1 in a horizontal manner, a rear end pipe orifice is closed, holes 21 are formed in two sides of the pipe wall, an air overflow preventing fin 4 is covered above the holes 21, the air overflow preventing fin 4 is long, and the air injection pipe 3 is arranged below the air overflow preventing fin 4.
Giving gas that gas injection pipeline 3 output sprays and having certain gas rush pressure, huge impact force stirs the ubiquitous to the silt deposit, makes the sludge blanket become the soft easy of inhaling of xi, and the mud that makes the soft easy of inhaling of xi simultaneously utilizes the depression under the combined action of water depth head pressure and gas impact force, gets into mud pipe 2 from hole 21 automatically, realizes the mud discharge purpose. Wherein, the gas can be accessed from a pressure gas source of a water treatment plant or supplied by a gas pump. Both sides have the slope in the pond, and mud pipe 2 is located the notch that both sides slope formed, and like this, mud is piled up to the notch along the slope gliding, concentrates the suction mud easily. The sludge discharge pipe 2 is horizontally placed at the bottom of the sludge settling tank to reduce the suction distance between the hole 21 and the sludge interface at the bottom of the tank, and increase the sludge suction area, so that the accumulated sludge at the bottom of the tank can be thoroughly discharged. The gas overflow prevention fin 4 arranged above the gas injection pipeline 3 not only prevents bubbles from overflowing and impacting and floating suspended matters in the water treatment tank to damage the normal work of water purification treatment, but also has a guiding function, so that gas flows in the space below the gas overflow prevention fin 4 to form required pressure difference. Wherein, the full length of the air overflow preventing fins 4 means that the fins are laid along the axial length of the mud pipe 2. The distance between the sludge discharge pipe 2 and the bottom of the pool can be determined according to the sludge discharge amount, but the sludge discharge pipe 2 is positioned above the sludge accumulation interface and is close to the sludge accumulation interface, so that the suction distance is minimized, the sludge suction efficiency is high, and the sludge is effectively sucked completely.

In some embodiments, as shown in fig. 3, the mud pipe 2 is mounted to the bottom of the pond by an adjustable H-shaped bracket 5. The adjustable H-shaped support 5 comprises an adjusting clamp 51, a screw rod 52 and a nut 53, the adjusting clamp 51 is sleeved on the sludge discharge pipe 1, one end of the screw rod 52 is fixed with the bottom of the tank, the other end of the screw rod passes through the adjusting clamp 51 to be perforated and is fixed through the nut 53, and the height of the adjustable H-shaped support is adjustable. The adjustable H-shaped bracket 5 is adopted to ensure that the sludge discharge pipe 2 is not only stably arranged at the bottom of the pool, but also the height is adjustable. Of course, the installation of the sludge discharging pipe 1 is not limited to the adjustable H-shaped bracket 5. The adjustable H-shaped bracket 5 is arranged on two axial sides of the mud discharging pipe 2, so that the interference of the installation of the gas overflow preventing fins 4 is avoided.
