Submersible stirring device

Abstract

The invention relates to a submerged stirring device, which comprises a bracket, a hollow rod, a main motor, a connecting shaft, a waterproof motor and two stirring paddles, wherein each stirring paddle is mainly composed of a stirring rod and a stirring impeller, the hollow rod is installed on the bracket through a sliding bearing, the main motor is installed at the bottom of the hollow rod, and is connected with the connecting shaft through a main speed reducer, the lower end of the connecting shaft is fixedly connected with the waterproof motor in a sealed mode, the waterproof motor is provided with two output shafts, the output shafts are connected with the stirring rods through 90-degree steering speed reducers, a gear rack is arranged on the outer side of the hollow rod, and a height adjusting gear meshed with the gear rack is installed on the bracket. According to the invention, the double-motor scheme of the main motor and the waterproof motor is adopted, wherein the waterproof motor is submerged in materials so as to shorten the length of the stirring rod and solve the problems of movement, poor stability, large torque and the like caused by the fact that the stirring rod stretches out too long, the main motor drives the whole stirring component to revolve, and the waterproof motor drives the two stirring paddles to rotate at the same time, so that the stirring effect is improved.

Description

technical field [0001] The invention relates to a stirring device, in particular to a submerged stirring device suitable for liquid-liquid and liquid-solid mixing. Background technique [0002] There are many types of stirring devices currently on the market, most of which are composed of a top motor and an extended stirring rod to form different stirring paddles. The existing stirring device has the following deficiencies in the use process: 1. The stirring rod of the traditional stirring device is too long, which will cause axial movement at high speed, and the stability is poor; 2. The stirring rod is too long, which will also cause stirring During the process, the torque on the stirring rod increases, which will seriously break and affect the service life; 3. The single-blade stirring device is simple in structure and easy to manufacture, so it is used more often. Flowing along the side wall of the drum, only when the high speed makes the water flow at high speed and ge...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a submerged stirring device, which adopts the scheme of a main motor and a waterproof motor, the main motor is installed at the lower end of the hollow shaft, and can dive above the solution, and the waterproof motor is submerged into the material Among them, the length of the stirring rod is shortened, which solves the problems of movement, poor stability, and large torque caused by the extension of the stirring rod. In addition, the main motor drives the entire stirring part to revolve, and the waterproof motor drives the two stirring paddles to rotate at the same time. the effect of stirring
