The invention relates to the technical field of automatic control, in particular to a slurry centrifugal separation system. The slurry centrifugal separation system solves the technical problems of unreasonable design and the like in the prior art. The slurry centrifugal separation system comprises a centrifugal solid-liquid separator, wherein the centrifugal solid-liquid separator comprises a rotary drum, and a slag hole and a liquid outlet are connected to the rotary drum. The slurry centrifugal separation system is characterized in that: the rotary drum is connected with a primary motor and a secondary motor which are capable of driving the rotary drum to rotate respectively; the primary motor and the secondary motor are connected with a primary frequency converter and a secondary frequency converter respectively; a feeding pump and a dosing pump are connected to the rotary drum; and the main frequency converter, the secondary frequency converter, the feeding pump and the dosing pump are connected with a controller. Compared with the prior art, the slurry centrifugal separation system has the advantages of reasonable design, simple and compact structure, high automation degree, simple process, good separation effect and low processing cost.
Description
technical field [0001] The invention relates to the technical field of automatic control, in particular to a mud centrifugal separation system. Background technique [0002] Slurry centrifugal separation equipment is a commonly used equipment in the field of engineering technology. In order to improve its performance, people have carried out long-term exploration and proposed various solutions. For example, the Chinese patent literature discloses a municipal engineering mud machine post-dosing centrifugal dehydration process [Application No.: CN98121906.3], which sends the mud into the centrifugal dehydrator for dehydration, and separates it into mud cake and tail water. Add coagulant to the coagulation area of the sedimentation tank for chemical dosing coagulation, separate into concentrated mud and clarified liquid in the sedimentation tank, and then return the concentrated mud to the centrifuge for separation. This process greatly reduces the dosage of chemicals, impro...
