A SYSTEM OF HYDRAULICALLY OPERATED PRESS FOR FORMATION OF COAL CAKE AND TROLLEY FOR TRANSFER OF COAL CAKE.

摘要

The present invention relates to a hydraulic press system for compaction of pulverized coal for making a compacted coal cake. This coal cake can be charged in a slot type pilot / experimental coke oven for coke making. The system of hydraulically operated press for compaction of a pulverized coal for making a coal cake and transferring the coal cake to a pilot / experimental coke oven comprising: a press cylinder with a top die attached to a top pressure plate for applying pressure on the pulverized coal charge filled in a mould box, the press cylinder having guide arrangement for ensuring a straight line motion of the press cylinder during pressing the pulverized coal charge in the mould box;_an ejector cylinder with a bottom die attached to a bottom pressure plate for ejecting the pulverized coal charge from a mould to the mould box after compaction of the pulverized coal charge having an ejector cylinder guided by mould box for ensuring a straight line motion of the ejector cylinder during ejecting a compacted coal cake from the mould to the mould box; a pusher cylinder with a pusher plate mounted on a bracket attached to the bottom pressure plate for pushing the compacted coal cake from the bottom die to a transfer trolley having a pusher cylinder guide arrangement for ensuring a straight line motion of the pusher cylinder during extension and retraction of the pusher cylinder. The transfer trolley comprises portable wheel(s), height adjustable, extendable and retractable table having guide arrangement and lock arrangement for proper receiving the compacted coal cake and transporting the compacted coal cake to the pilot / experimental coke oven; a hydraulic power pack for providing required pressure for motion of the press cylinder, the ejector cylinder and the pusher cylinder during pressing, ejecting and pushing of the pulverized coal cake during compaction. The electrical system comprises main electrical panel and operator control panel for providing power and controlling the functions of hydraulic power pack.
