Description

Hydraulic transmission suspension type underwater flow impeller

Technical Field

The utility model relates to a push away and flow and stirring field under water among the sewage treatment plant sewage treatment process especially relates to a hydraulic drive suspension type impeller under water.

Background

At present, most of large and medium-sized sewage treatment plants, whether the oxidation ditch process, the A/O, A/O process or the SBR (sequencing batch reactor) process, adopt a flow pusher and a stirrer (hereinafter referred to as the flow pusher) for water body mixing; at present, two types of underwater water impellers exist, one type is a submersible water impeller, and a motor, a speed reducer and an impeller of the submersible water impeller are arranged below the water surface; the second is a suspended underwater propeller, the motor and the speed reducer of which are on the water surface, and the paddle steering box is under the water surface. The functions of the sludge and the sludge are to push the water body to keep a certain flow velocity to flow forwards or stir, so that the activated sludge is uniformly dispersed in the water and cannot be precipitated.

However, with the two technical solutions, the main advantages and disadvantages are as follows: the underwater impeller is an important means and equipment in the activated sludge treatment process. The submersible water impeller has the advantages that the submersible water impeller is compact in structure, the motor and the speed reducer are underwater, and no noise is generated on the ground; the defect is that after the sealing element is used for a period of time (generally about two years), the motor is easy to be burnt out by water due to the abrasion of the sealing element, and simultaneously, the fatigue damage or the loosening and damage of underwater foundation bolts can be caused by the huge alternating stress generated by the fixed guide rod due to the action of the flow pusher; in our daily maintenance work, the probability of the damage of the fixed guide rod is not inferior to the damage of the motor, and once the fixed guide rod is damaged, the repair is very difficult, because the base of the fixed guide rod is arranged at the bottom of the water tank, water needs to be completely pumped out, thus causing partial or even complete production stop of a sewage treatment plant, thus bringing great economic loss and environmental pressure to the sewage treatment plant and the local area, the other defect of the equipment is fixed rotating speed, and difficult to realize energy saving and more ideal process requirements, the application No. 201220620485.0 discloses a suspension type underwater propeller, the core content of which is that the motor and a speed reducer are arranged on the water surface, the operation fault caused by water inlet of the motor does not exist, the overhaul and the maintenance are convenient, the maintenance cost is low, the other advantage is that the structure is complex, slight noise exists on the water surface, although the rotating speed can be changed by changing the, the single is relatively cumbersome. The connecting part of the overwater speed reducer and the underwater working part is a long rod shaft provided with a universal coupling, and the long rod shaft is not suitable for middle-high speed rotation of more than 150r/min, so that the development and utilization of the suspension type middle-high speed plug flow or the stirrer are limited.
