HYDRAULIC PRESS FOR BRIQUETTING OF VEGETABLE MATERIALS Russian patent published in 2003 - IPC

FIELD: hydraulic presses for briquetting of organic materials of vegetable origin, raw waste lumber inclusive, applicable for manufacture of non-plane hollow briquettes used a fuel both for municipal and production needs. SUBSTANCE: the hydraulic press for briquetting of vegetable materials has a baling chamber that is formed by end plate 1 located on frame 2 and rigidly connected to rear plate 12, upper (3) and lower (4) plates installed in end plate 1 and interconnected between each other, fixed members 7 with concave curvilinear surfaces positioned between the mentioned upper (3) and lower (4) plates fastened in end plate 1, input bushing 8 and movable working members 9 with curvilinear concave surfaces. The movable working members 9 are linked by leverages 10 to hydraulic cylinders 11 fastened on rear plate 12. A spinneret for packing the briquette is installed in end plate 1. Loading device 17 is installed on upper plate 3. Movable shutter 18 fastened on plate 3 is a fragment of the duct wall of loading device 17. Movable shutter 18 through links 19 is connected to hydraulic cylinder 20 serves as an additional pressing member. Installed in rear plate 12 is hydraulic cylinder 22 of the pressing device, Punch 23 serves for the purpose. A hole- forming core is fastened in punch 23. Heater 26 may be installed on the hydraulic press for briquetting of vegetable materials. EFFECT: uniform pressing due to successive action on the material to be pressed in mutually perpendicular vertical, side and axial directions. 13 cl, 3 dwg
