Sewage stirring treatment device utilizing planetary gear transmission principle

Abstract

The invention relates to the technical field of sewage treatment. The invention further discloses a sewage stirring treatment device utilizing a planetary gear transmission principle. The device comprises a stirring kettle, and a support frame is fixedly connected to the outer part of the stirring kettle. The top of the stirring kettle is fixedly connected with an adjusting frame. The top of the adjusting frame is fixedly connected with a speed reducer. A motor is fixedly connected to the exterior of the speed reducer. Balls are movably connected into the adjusting frame. The outer portions ofthe balls are movably connected with an outer gear ring. The interior of the outer gear ring is connected with transition gears in an engaged mode. The outer gear ring, the transition gears and a central gear are matched for use, so that the effect that a sleeve shaft and a center shaft rotate reversely is achieved, outer stirring blades and inner stirring blades rotate reversely, the stirring effect is improved, the stirring efficiency is improved, sewage and liquid medicine are fully mixed, the sewage treatment effect is improved, frequent reverse rotation of the motor is avoided, it is guaranteed that the motor rotates in the same direction all the time, and the service life of the motor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage stirring treatment device utilizing the principle of planetary gear transmission. Background technique [0002] Water pollution is the reduction or loss of the use value of water caused by harmful chemical substances, polluted water, acids, alkalis, oxidants in sewage, and compounds such as copper, cadmium, mercury, arsenic, benzene, dichloroethane, ethylene dichloride, etc. Alcohol and other organic poisons will kill aquatic organisms and affect drinking water sources and scenic spots. When the organic matter in the sewage is decomposed by microorganisms, the oxygen in the water is consumed, which affects the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition, producing hydrogen sulfide, mercaptan and other unpleasant gases, which further deteriorates the water quality. The proc...

Problems solved by technology

[0003] Sewage treatment requires dosing and mixing of sewage. After dosing, it is necessary to stir the medicine and sewage, so that the medicine and sewage can be mixed quickly. However, the existing stirring device is usually equipped with a single shaft, and a stirring blade is arranged on the stirring shaft. , the stirring blade is driven by the stirring shaft to stir. However, when stirring in this way, the sewage will form a vortex in the center due to the centrifugal force, and the sewage will rotate with the stirring blade during stirring, resulting in low stirring effect, resulting in the liquid medicine and The sewage is mixed unevenly, which makes the sewage treatment effect unsatisfactory, and the positive and negative rotation of the motor drives the positive and negative rotation of the stirring shaft. Although the stirring effect can be increased, the positive and negative adjustment has a buffer time, which leads to a decrease in the stirring efficiency, and frequent control of the motor Forward and reverse rotation will greatly damage the internal structure of the motor and reduce the service life of the motor

[0004] In addition, when stirring in the stirred tank, a large amount of garbage in the sewage will often remain on the inner wall of the stirred tank. If it is not treated for a long time, the remaining garbage will corrode the inner wall of the stirred tank, thereby reducing the service life of the stirred tank. Moreover, because the stirring tank is often a sealed device, it is very troublesome to clean up, time-consuming and laborious, and a lot of water resources need to be wasted during cleaning.
