Description

Novel adjustable suspension type impeller

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 novel adjustable suspension type plug flow device.

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.

The current Chinese patent CN201220620485.0 discloses a suspended underwater flow impeller, which comprises an upper base, a lower base, a motor and a stainless steel wire rope, and is characterized in that the motor is connected with a speed reducer and fixed at the upper end of the upper base, the upper base and the lower base are connected through a suspended fixed rod, the lower base is connected with a speed reduction steering gear, and the speed reduction steering gear is connected with the speed reducer through a universal coupling at the upper end of a transmission shaft; a suspension shaft is arranged at the upper end of the suspension type fixed rod; the suspension shaft is arranged on the suspension bracket; the lower end of the suspension type fixed rod is provided with a transverse fixed rod; the transverse fixed rod is connected with the tensioning device through a stainless steel wire rope; the speed reduction steering gear drives the blades on the blade seat to rotate through the power of the motor and the speed reducer.

Above-mentioned structure must pass through stainless steel wire rope pulling transverse fixing pole to when guaranteeing that the paddle is rotatory, guarantee the balanced stress of paddle in aqueous all the time, but the problem that this design exists is for guaranteeing wire rope's tractive, need reserve wire rope's fixed position, but wire rope's fixed position has not all places all been predetermine, the position that even more probably impeller installation is only a bridge floor, can't provide the mounted position for other parts of hanger impeller at all, so lead to the unable adaptation of all kinds of installation environment of this design.
