Gas stripping sludge discharge device

Abstract

The invention provides a gas stripping sludge discharge device comprising a horizontal gas tank, wherein a hand hole is formed in a side wall of an upper end of the gas tank, a sludge inlet pipe is arranged at a position close to the side wall of a left end on a lower end of the gas tank, a sludge outlet pipe is arranged at a position close to the bottom on a right end of the gas tank, the sludge outlet pipe is connected with a sludge header pipe, an exhaust pipe is arranged on one side of the hand hole, a brake valve is arranged on the exhaust pipe, the sludge inlet pipe is connected with a sludge suction pipe through a movable joint, a sludge suction horn mouth is arranged at a bottom end of the sludge suction pipe, a *-shaped rotating blade is arranged at the center of the sludge suction horn mouth, an air inlet pipe is arranged at a 1 / 3 height of the sludge suction pipe from bottom to top, the air inlet pipe is connected with a blower, the air inlet pipe stretches into the sludge suction pipe, the pipe orifice is vertically upward, a flow guide ball is arranged right above the sludge suction pipe in the gas tank, and symmetrical arc-shaped flow guide plates are arranged on the top left side and the top right side of the gas tank.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a sludge gas lift device. Background technique [0002] The air-lift mud discharge device consists of an air-lift tank, a mud outlet pipe, a mud inlet pipe, an exhaust pipe, an air inlet pipe, a mud suction bell, and a mud suction bell bracket. The mud suction bell bracket is set on the One end of the mud suction bell is fixed on the bottom of the sludge tank, and the other end of the mud suction bell is connected to the mud inlet pipe; when working, inject compressed air into the inlet pipe, and the compressed air drives the air in the mud inlet pipe to flow to the gas tank. After the mud is pumped into the mud inlet pipe, it flows to the gas tank. [0003] However, the bell mouth is easy to block when sucking mud, resulting in poor mud suction, and the existing inlet pipe port is easy to enter the sludge, resulting in poor air outlet. After the sludge is sucked into the tank, t...

Problems solved by technology

[0003] However, the bell mouth is easy to block when sucking mud, resulting in poor mud suction, and the existing inlet pipe port is easy to enter the sludge, resulting in poor air outlet. After the sludge is sucked into the tank, the mud will radiate, and the energy consumption is high. , it is necessary to guide the sludge well to the outlet pipe, none of the existing technologies solves the above problems and needs to be improved
