Low-speed submersible water impeller without gearbox

Abstract

The low-speed gearbox-free submersible water impeller comprises a frame, a direct-drive toothless assembly, an impeller, a convenient mounting and dismounting assembly and a cable, a mounting plate is fixedly connected to the lower portion of the right side of the frame, the direct-drive toothless assembly is arranged above the mounting plate, the impeller is detachably connected to the right end of the direct-drive toothless assembly, and the convenient mounting and dismounting assembly is mounted below the direct-drive toothless assembly. A cable is arranged above the direct-drive toothless assembly, a rubber plug is arranged on the left side of an inner hexagonal insertion block and slidably connected with the outer surface of the shell, a first ring is arranged at one end of a worm, a second ring is arranged below a turbine, a rotor is driven by a coil in the middle to drive a rotating shaft to rotate, an impeller is directly driven to work and rotate, and therefore the connecting mode of a conveyor and a motor is improved; a speed-changing gear box is omitted, use cost is saved, installation and maintenance are more convenient, the motor meets the requirement for the conveying capacity through an additionally-arranged elastic control system, a gear does not need to be replaced, a gear box does not need to be repaired or maintained, the whole machine runs at a low speed, and the service life is prolonged by several times.

Description

technical field [0001] The invention relates to the technical field of flow propellers, in particular to a low-speed gearless submersible flow propeller. Background technique [0002] The submersible flow propeller is a kind of mixing and stirring and low-speed propelling flow. The mixers of the low-speed push-flow series are mainly suitable for aeration tanks and anaerobic tanks in industrial and urban sewage treatment plants, etc. They produce strong water flow with low tangential flow, which can be used for water circulation in the tank and the creation of water flow in the stages of nitrification, denitrification and phosphorus removal. Wait. [0003] The prior art submersible flow propellers are all equipped with a gearbox structure. The cost of the variable speed gearbox is high, and it consumes electricity during use. After a period of use, maintenance and oil changes are required. Maintenance is very troublesome, time-consuming and labor-intensive. Maintenance costs...
