Abstract

The invention discloses a hydraulic system of a press stripper dedicated for press stripping of a ferrophosphorus ring on an anode rod in a carbon plant in the electrolytic aluminum industry. The system consists of a clipping circuit, an ejection circuit and a heat dissipation and filtration circuit. A front pump, that is, a constant pressure pump of a twin pump (16) in the clipping circuit is sequentially connected with a pressure reducing valve (20), an electro-hydraulic directional control valve (21), a one-way throttle valve (22), a hydraulic control one-way valve (26), a pressure relay (28) and a clipping oil cylinder (30); the front pump (the constant pressure pump) and a rear pump (a remote constant pressure pump) of the twin pump (16) in the ejection circuit are sequentially connected with two stages of pilot overflow valves (13, 14, 29), two one-way valves (23), an electro-hydraulic directional control valve (24), an electromagnetic unloading valve (27), the pressure relay (28) and an ejection cylinder (31); and a gear pump (7) in the heat dissipation and filtration circuit is connected with a cooler (11) controlled by an electromagnetic water valve and a filter (12) with a bypass back pressure valve and a blocking warning device.

Description

technical field [0001] The invention relates to a press-off machine hydraulic system specially used for pressing off the phosphorus iron ring on the anode guide rod in the carbon workshop of the electrolytic aluminum industry. Background technique [0002] There are many types of equipment used for dephosphorization in industrial production, such as rack and pinion structures and pneumatic connecting rod structures. If it is small, it is difficult to complete the operation smoothly, or it is too precise and expensive, the investment in equipment is large, and the production cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a press-off machine hydraulic system, which can be used to press off the phosphorus iron ring on the anode guide rod in the press-off machine, so as to overcome the relatively small pressure-off force of the press-off equipment in the prior art It is difficult to complete the opera...
