Problems solved by technology

The cycloidal differential can provide too little torque, and the hydraulic differential is too expensive to be popularized. The output torque of the planetary gear differential is large, but the processing form of the current differential generally adopts the integral of the planetary gear carrier and the planetary gear shaft. In addition, in some application fields where separation is difficult, it is necessary to use a multi-stage planetary gear differential to meet the output torque required by the centrifuge, which further increases the use of planetary gear differentials. The cost of the gearbox separator
In addition, the integral processing method of the differential will also lead to higher maintenance or component replacement costs during the subsequent use of the separator

Description

technical field [0001] The invention relates to the technical field of separators, in particular to a planetary gear differential and a vertical liquid-solid centrifuge using the planetary gear differential. Background technique [0002] Separator uses the principle of different density and immiscible light, heavy liquid and solid phase in the mixed liquid to obtain different settling velocities in the centrifugal force field, so as to achieve the purpose of separating layers or settling solid particles in the liquid. It is mainly used in chemical industry, mineral processing, petroleum, pharmaceutical, food and other industries, as well as sewage treatment with foul smell and other occasions that require sedimentation and separation of solid-containing suspensions. [0003] Existing screw unloading sedimentation separator mainly is made up of rotating drum, screw pusher, differential gear, feed pipe and transmission device etc. During the process of concentration, dehydrat...
