Full hydraulic drive differential horizontal screw centrifuge

Abstract

The invention discloses a full hydraulic drive differential horizontal screw centrifuge, belonging to the horizontal screw centrifuge. The full hydraulic drive differential horizontal screw centrifuge comprises a horizontal screw centrifuge body, a driving motor and at least two hydraulic pumps, wherein the hydraulic pumps are in power connection with the driving motor. The full hydraulic drive differential horizontal screw centrifuge further comprises a hydraulic motor and a hydraulic differential; the hydraulic motor is in power transmission with a rotary drum on the horizontal screw centrifuge body; the hydraulic differential is in power transmission with one end of a screw pusher arranged in the horizontal screw centrifuge body; the hydraulic differential and the hydraulic motor are connected with different hydraulic pumps through circulating pipes; and the circulating pipes are provided with control blocks for controlling the output of the hydraulic oil. The full hydraulic drive differential horizontal screw centrifuge is simple in structure, is superior to the differential horizontal screw centrifuge of the same type in the prior art in the driving form, has high use reliability and wide range of application and is particularly suitable for separating cement, mud and other materials.

Description

technical field [0001] The invention relates to a decanter centrifuge, more specifically, the invention mainly relates to a full hydraulic drive differential decanter centrifuge. Background technique [0002] Decanter centrifuge is a horizontal spiral unloading and continuous operation settling equipment. Its working principle is that the drum and the screw rotate at a high speed in the same direction at a certain differential speed. After entering the drum, under the action of the centrifugal force field, the heavier solid phase is deposited on the drum wall to form a sediment layer. The conveying screw continuously pushes the deposited solid phase to the cone end of the drum, and is discharged out of the machine through the slag discharge port. The lighter liquid phase forms an inner liquid ring, continuously overflows the drum from the overflow port at the large end of the drum, and is discharged out of the machine through the liquid discharge port. At present, decanter...
