Overwater driving type underwater water impeller

Abstract

The invention discloses an overwater driving type underwater water impeller. A motor is fixed to the upper end of a supporting cylinder. The tail end of the supporting cylinder is submerged underwater and fixed to the upper face of a reversing reduction gearbox. A transmission vertical shaft is arranged in an inner cavity of the supporting cylinder. One end of the transmission vertical shaft is connected with an output shaft of the motor. The other end of the transmission vertical shaft is connected with an input shaft on the reversing reduction gearbox submerged underwater. A supporting rod is arranged at the adjacent position of the supporting cylinder side by side. The supporting rod and the supporting cylinder are connected through a fixing frame and fixed through a connecting plate. A stainless steel wire rope fixing frame is arranged on the supporting rod. An impeller body is installed on the input shaft of the reversing reduction gearbox. A supporting frame at the upper end of the supporting rod is fixed to a walking table through expansion bolts. A hoisting rack is fixed to the supporting frame through expansion bolts. One end of a stainless steel wire rope is fixed to the stainless steel wire rope fixing frame on the supporting rod. The other end of the stainless steel wire rope is connected with one end of a basket bolt. A basket bolt connecting frame is fixed to a wall of an oxidation ditch through expansion bolts.

Description

technical field [0001] The invention relates to a water-driven underwater pusher, which is especially suitable for the oxidation ditch process in the sewage biochemical system in the field of sewage treatment and the underwater convection of sewage in SBR (sequencing batch type). Background technique [0002] In the vast majority of large and medium-sized sewage treatment plants at present, whether it is the oxidation ditch process or the SBR (sequencing batch) process, a large number of pluggers are used. There are two types of flowmakers, one is a submersible flowmaker, its motor, reducer, and blades are under the water surface; the other is a surface aeration flowmaker (with aeration function), its motor , reducer, and paddles are above the water surface. Their functions are to push the water body to maintain a certain flow rate to flow forward or stir, so that the activated sludge can be evenly diffused in the water without sedimentation. Both the submersible flowm...

Problems solved by technology

The disadvantage is that after a period of use, due to the wear and tear of the seals, the motor is easily burned by water, and the cables are often worn out due to the constant swing of the water flow. Fatigue failure or loosening and damage of underwater anchor bolts

Since the base of the fixed guide rod is at the bottom of the pool, all the water needs to be pumped out to repair, and it is impossible for the sewage treatment plant to stop the water inflow, so once the underwater pusher is broken, it cannot be restored
