Description

Submersible water impeller with novel structure

Technical Field

The utility model relates to the field of underwater sludge plug flow and stirring in a sewage treatment process, in particular to a submersible water plug flow device with a novel structure.

Background

At present, most of large and medium-sized sewage treatment plants, whether the oxidation ditch process or the SBR (sequencing batch reactor) process, generally adopt a flow pusher and a stirrer (hereinafter referred to as the flow pusher); the impeller has two types, one is a submersible impeller, and a motor, a speed reducer and blades of the submersible impeller are arranged below the water surface; the other is a surface aeration impeller (with aeration function), and a motor, a speed reducer and an impeller of the surface aeration impeller are all arranged above 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, by adopting the two technical schemes, the main advantages and disadvantages are as follows: both the submersible water impeller and the surface aeration impeller are important means and equipment in the activated sludge treatment process. The surface aeration impeller has the advantages that the equipment is above the water surface, is convenient to maintain and is not easy to damage; the disadvantage is that the depth of the pool (ditch) can not be too deep, which is generally not more than 3 meters, thus the occupied area and the investment of civil engineering facilities are greatly increased. The submersible water impeller has the advantages that the depth of a pool (ditch) can be made larger, generally 6-7 m, so that the occupied area and the investment of civil facilities are reduced, and the flow velocity of a water body is more uniform; 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 fixed guide bar damage is not inferior to even motor damage, and in case damage, repair is very difficult, because fixed guide bar base is in the pond bottom, need take out water totally, causes sewage treatment plant local or even whole stopping production, can bring very big environmental pressure and economic loss for sewage treatment plant and local like this.

But the structure of the submersible water impeller also has certain advantages, so how to realize the quick assembly, disassembly and maintenance of the submersible water impeller without draining the water pool, and the problem to be solved can be realized that the manufacturing cost is reduced, the further popularization is facilitated.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems mentioned in the background technology, the utility model aims to provide the submersible water impeller with a novel structure, which can realize the effects of water-carrying installation, simple and convenient maintenance and replacement operation and low cost investment.

The technical purpose of the utility model is realized by the following technical scheme: the utility model provides a dive impeller of novel structure, includes dive impeller, impeller bracket and hangs the frame, the impeller bracket is installed in the bottom that hangs the frame, dive impeller installs on the impeller bracket, still includes mounted frame and chain block, the mounted frame with hang frame normal running fit, still be equipped with a plurality of hangers in the frame that hangs, chain block and hanger detachable connection.

Preferably, a steel wire rope supporting plate is arranged on the suspension rack, and one end of the steel wire rope is connected with the steel wire rope supporting plate.

Preferably, the device further comprises a back support which is arranged at the back of the suspension frame.

Preferably, the chain block is mounted on the lifting frame base through a lifting frame.

Preferably, the diving flow driver comprises a diving motor, a speed reducer, an impeller and a blade, the body of the diving motor is installed on the flow driver bracket, the diving motor is connected with the impeller through the speed reducer, and the blade is installed on the impeller.

Preferably, the submersible water impeller is detachably connected with the suspension rack through a fixing plate.

In summary, the utility model mainly has the following beneficial effects: the submersible water impeller with the novel structure has the advantages that on one hand, the submersible water impeller can be installed with water, meanwhile, the installation convenience is guaranteed in a quick lifting mode, meanwhile, the structural design of the steel wire rope and the back support piece can achieve the stable work of the submersible water impeller, the cost is lower due to the adoption of a single hanging rack mode, the popularization is easier, moreover, the lifting of the submersible water impeller can be completed by the chain block, the rotary lifting of the hanging rack can be pulled, and the effect that water drainage is not needed in a pool during maintenance is achieved.
