Embodiment Construction

[0010] refer to figure 1 , the briquette extrusion device of the present invention, workbench 1 is provided with motor 2, and the output end of motor 2 is connected speed reducer 3, and the output end of speed reducer 3 is connected propulsion shaft 5 ( figure 1 The structure of the propulsion shaft is only schematically shown in the figure), and the propulsion shaft is provided with a feeding pre-compression section S4, a pressurization section S3, an extrusion melting section S2 and a homogenization section S1 composed of helical blades. The outer diameter D1 of the helical vane in the section S4 is larger than the outer diameter D2 of the helical vanes in the pressurizing section, extrusion-melting section and homogenizing section. The two ends of the propulsion shaft are assembled in the twisted cage 4, and the front upper end of the twisted cage 4 communicates with the coal inlet 6. The coal inlet 6 is provided with a twisted gear shaft 7, and the twisted gear shaft 7 is ...

Abstract

The invention discloses a coal ball extrusion apparatus. The apparatus is characterized in that: a workbench is provided with a motor; an output terminal of the motor is connected with a decelerator; the output terminal of the decelerator is connected with a propulsion shaft; the propulsion shaft is provided with a feeding prepress segment, a pressurizing segment, an extrusion fusion segment and a homogenization segment which are composed of spiral blades; the external diameter D1 of the spiral blades of the feeding prepress segment is greater than the external diameter D2 of the spiral blades of the pressurizing segment, the extrusion fusion segment and the homogenization segment; two ends of the propulsion shaft is assembled in a wring cylinder; an upper end at the front of the wring cylinder is communicated with a coal inlet; a wring tooth shaft is arranged in the coal inlet; the wring tooth shaft is provided with wring teeth; the wring tooth shaft is connected with the output terminal of the decelerator through a transmission device; an exit of the wring cylinder is provided with a coal extrusion plate with a through hole; a main shaft out of the coal extrusion plate is provided with a cutter; and the main shaft of the external cutter is fixedly provided with a roller which is provided with an opening at one end.

Description

technical field [0001] The invention relates to the technical field of extrusion, in particular to a briquette extrusion device. Background technique [0002] The traditional processing machinery used to make briquettes generally has a structure in which the motor drives two parallel extrusion rollers designed in opposite directions on the body, and the semicircular briquette grooves are set on the two extrusion rollers, and then the pulverized coal is placed Make it wet in the stirrer, squeeze it through two counter-rotating extrusion rollers, and buckle and squeeze the coal in the semicircular briquette groove into spherical briquettes. This extruded briquette is easy to loose, or the density is high and the extrusion is too tight, so it is not easy to burn through, and the use effect is not good. This is due to the fact that the coal distributed on the two extrusion rollers is uneven and requires that the extruded coal can only pass through. However, the traditional han...
