Abstract
The utility model relates to an improved device of a screw extruding machine, which belongs to the technical field of machinery profession. The utility model is characterized in that hard alloy blocks or high-speed steel bars are welded or riveted with the radial edges of screw blades on a screw axle; dovetail grooves and flutes are uniformly distributed at intervals according to circumference in a bush of the screw extruding machine; the wearable high-speed steel bars are inserted into the dovetail grooves; the structure of a movable pressing nozzle is groove-shaped steel; the movable pressing nozzle and a movable pressing board arranged on the movable pressing nozzle forms an oblong feed opening above which a pressure applying device of an oil pressure spring is arranged. The utility model has the characteristics that a gap between each of the screw blades and the surface of the bush can be kept, and the spring pressure applying device can be used on the pressing board of the movable pressing nozzle. The quality of molded coal is enhanced.
Description
The utility model relates to mechanical field, in particular for the preformed screw extruder of fine coal hot pressing.
Screw extruder is used for fine coal hot pressing preformed, is about to be heated rapidly to the hot coal powder of plasticity temperature range, becomes the plasticity coal charge through screw press in screw extruder, is extruded into the plasticity ribbing through distortion mouth and movable pressure mouth.There are the Germany and the former Soviet Union in the country that mainly develops moulded coal of hot pressing and hot briquette formed coke technology in the world.The BFL hot briquetting process and the Ancit hot briquetting process of Germany's exploitation do not use hot pressing preformed equipment.The IGI hot briquetting process of former Soviet Union's exploitation then adopts crawler type to tie up warm preformed equipment.Use screw extruder as hot pressing preformed equipment at the solid thermophore of China exploitation or gas thermophore moulded coal of hot pressing or formed coke technology always.But because helical blade and lining material are not wear-resisting, only 1-2 months its service life.
The purpose of this utility model provides a kind of preformed screw extruder of fine coal hot pressing that is used for, can improve the service life of helical blade and lining, be convenient to the more wearing piece of resleeve,, improve the year operating rate of whole production device to guarantee the gap between helical blade and the lining.And a kind of movable pressure mouth device for exerting is provided, improve the quality of products.
The utility model content Description:
A kind of preformed screw extruder of fine coal hot pressing that is used for, it is characterized in that: the helical blade longitudinal edge on the helical axis is along welding-on or riveted joint hard alloy blocks or the high speed steel bar after quenching, press uniform dovetail groove of circle spacing and Baltimore groove in the lining of screw extruder, in dovetail groove, insert the high speed steel bar after quenching, movable press nozzle structure is a channel-section steel, constitute rectangle hole with its movable pressing board that is provided with above, channel-section steel is welded in the downside of the laterally zygomorphic rectangle hole of flange center, be welded with slew page on the movable pressing board, the another side of slew page is welded in the upside of flange rectangle hole, movable pressing board can swing up and down in channel-section steel, is provided with the hydraulic spring device for exerting on movable pressing board.
Characteristics of the present utility model: the helical blade longitudinal edge is very wear-resisting behind the seting welding carbide piece, and the high-speed steel bar that the lining inside groove is inserted after edge quenches forms wear-resisting inner surface, is convenient to also change that high-speed steel is transplanted a cutting and resleeve more not.Can keep the gap of helical blade and sleeve surface for a long time and improve the service life of equipment and the ribbing quality of pre-molding, use spring device for exerting equipment little on the pressing plate of movable pressure mouth, use and easy to adjust.
