Description

Submersible mixer device for lake water using air motor

The present invention is an underwater mixer device for lake water using an air motor that can be used as an underwater mixer installed on the bottom of lake water to form a flow to circulate the entire stagnant water such as a lake or pond at a proper flow rate in a certain direction. It is about.

Propelling water by the propeller's rotational force by driving the motor connected to the conventional underwater mixer power, the flow was formed to circulate the stagnant lake water, but this is due to the electrical installation work connected to the floor from the outside of the lake water Expensive purchase and installation costs are required, and the damage caused by the aging of the electric equipment is caused when it is used for a long time, causing electricity to flow to the appealing water, which not only increases the risk of electrocution and death of fish, but also increases the cost of replacement. The conventional air motor driven by supplying air at a necessary pressure by a compressor is inexpensive, but has a disadvantage in that it cannot be used as an underwater mixer of appealing water because it is not waterproof.

The present invention has been devised to solve the above-mentioned defects, the inlet side, the middle part, the rear motor case formed in a cylindrical body on the upper part of the lower fixing plate to be integrally addressed to seal the rubber packing so that leakage does not occur inside. The screw is fixed by screwing through the ring, and a normal air motor driven by compressed air is driven by a compressor inside the rear motor case, and the screw is fixed and connected to supply compressed air, and at the same time on the motor shaft of the air motor. Inserting and connecting the interlocking connecting shaft, the bearing, mechanical seal, and retaining can be smoothly rotated while preventing leakage of the inside of the motor case and the flow of the connecting shaft between the inlet side and the central part inside the middle motor case. Retaining ring is sequentially fixed to the connecting shaft and extends outside the inlet motor case. The propeller which propels water by the rotational force of the air motor is inserted into and fixed to the connected shaft, and the water supply guide is formed around the propeller to form a flow such that the water is circulated by the water being pushed in a predetermined direction. The air outlet is connected to the socket formed at the bottom of the rear motor case and the air outlet is connected to the rear of the propeller so that the air discharged into the motor case by the silencer of the air motor can be supplied to the lake water for reuse. In order to prevent the backflow of water and to maintain the safety of the check valve that discharges air by the air pressure discharged into the motor case, two are installed and assembled at an appropriate distance. , Prefabricated.
