The application discloses a pressure reversing device of a pusher centrifuge and a control method thereof, and is characterized by further comprising an oil tank, an oil pump connected with the oil tank through a pipeline, a valve island connected with the oil pump through a pipeline, an oil inlet pipeline and an oil return pipeline arranged on the valve island, a main valve arranged on the valve island and communicated with the oil inlet pipeline and used for controlling oil supply to a left end pushing chamber or a right end pushing chamber, and a pilot valve arranged on the main valve and communicated with the oil inlet pipeline and used for controlling reversing of the main valve and controlling reversing of a piston. After the piston in the oil cylinder moves to a position, the piston cannot be switched due to the fact that the oil inlet pipeline is not switched and the oil inlet pipeline is not communicated, so that the pressure of the hydraulic system is rapidly increased. The reversing of the main valve and the pilot valve is controlled by using the rapidly increased pressure, and then the reversing of the piston is controlled. The reversing signal is generated by the increase of the pressure in the hydraulic system after the piston moves to the position, so that the switching of the piston after the piston moves to the position can be effectively ensured, and the problem of short pushing of the pusher centrifuge is avoided.

This utility model discloses a hydraulic oil iron filings filtration device for a piston-feeding centrifuge. Its features include a guide plate and chip baffle mounted on a side rib, an iron filings bubble filter frame mounted on the side rib and above the guide plate and chip baffle, a filter screen on the iron filings bubble filter frame to eliminate air bubbles as the hydraulic oil passes through, and several magnetic strips on the iron filings bubble filter frame for filtering iron filings. Through the guide plate and magnetic strips, when iron filings travel with the hydraulic oil from the return oil zone through the oil cooling zone, the guide plate and chip baffle prevent the hydraulic oil from reaching the suction zone only through the iron filings bubble filter frame. As the hydraulic oil passes through the iron filings bubble filter frame, the iron filings are attracted by the magnetic strips on the frame, thus filtering the iron filings in the hydraulic oil. This prevents iron filings from re-entering the pressure cylinder with the hydraulic oil, which would aggravate wear on moving parts, leading to abnormal noise or complete damage to the piston assembly.

This utility model discloses a feeding trough structure for a double-push, double-discharge type centrifuge, relating to the field of centrifuge technology. It has the advantage of reducing material adhesion to the inner wall of the feeding trough. The key technical points are: it includes a surrounding plate connected to the centrifuge product chamber via a connector; the surrounding plate is a semi-circular arc plate coaxially distributed with the drum; vertical plates are provided at both ends of the surrounding plate; gaps exist between the surrounding plate and the vertical plates and the outer wall of the drum, and they are distributed directly opposite the discharge port on the drum; and an anti-adhesion lining layer is provided on the side of the surrounding plate and the vertical plates facing the outer wall of the drum.

This invention discloses a pusher centrifuge for direct separation of heavy alkali, belonging to the technical field of heavy alkali centrifuges. It includes an oil tank that also serves as the machine base, a bearing housing fixed thereon supporting a hollow shaft, and a pusher shaft nested within the hollow shaft, rotating synchronously via a guide key and driven reciprocating by a compound piston. Three concentrically nested drums, each containing cylindrical and conical sections, are used. Each drum has a corresponding screen and pressure ring fixed to it. A pusher plate connects to the bottom of the second-stage drums, and a feeding cone is mounted on the pusher plate, with a feed pipe extending into the feeding cone. Multiple wash water pipes are installed at the product chamber door, their positions adjustable via adjusting bolts. Waste washing liquid and circulating washing liquid gas-liquid separators are connected to the drum drain ports, with the circulating liquid returning to the wash water pipes. A partition seal is installed between the bearing housing and the product chamber, and a stuffing box seal is installed between the bottom of the third-stage drums and the pusher shaft. This device improves separation efficiency and resource utilization through staged centrifugal dehydration and adjustable washing.
