Platen is respectively disposed in corresponding guide groove, and is moved under the driving of drive component along guide groove.
During design, back pressure disk uses the shape of semi-circular shape, and the internal diameter of back pressure disk discharges more than or equal to screw spindle 4
The external diameter of section.When a pair of back pressure disks are in closure state, the inwall of a pair of back pressure disks is just fastened on screw spindle discharging section
Outer wall on so that confined space is formed between screw spindle discharging section and inboard wall of riddle drum, material is extruded compression；And when a pair
When back pressure disk is in open mode, outer wall of the inwall of a pair of back pressure disks away from screw spindle discharging section, i.e. above-mentioned confined space
Open so that the material compressed between screw spindle discharging section and inboard wall of riddle drum is fallen at grout outlet 1 from opening.Phase
Answer, during design, the direction of motion of the piston rod of pneumatic cylinder or hydraulic cylinder should be made parallel with the radial direction of screw spindle or again
Close.
In addition, the discharging that the screw spindle discharging section of the present embodiment is also set up for crushing compressed material crushes rod 3, discharging
The quantity of broken rod 3 can be one or more (being four in figure), and the broken rod 3 of more dischargings is uniformly placed in screw spindle 4
The periphery of discharging section.Preferably, discharge one end of broken rod 3 is connected with the outer wall of screw spindle 4, and the other end is along screw spindle 4
Radially extension.
Wherein, in the single-screw press master of the present embodiment, the discharging section of screw spindle 4 for one section of not reducing d-axis 5, no
The part of the d-axis 5 of reducing has one section without helical blade, is that material plug forms area 6, material plug forms the axial length in area in 230-
Between 390mm.A pair of back pressure disks 2 are arranged on material plug and formed at the grout outlet 1 outside area 6, in the presence of two side pneumatic cylinders 7, one
To back pressure disk 2 along guide groove to both sides closure or openness.
The present embodiment single-screw press master start shooting initial stage, because inlet amount is few, back pressure disk it is 2-in-1 hold together, after de-watering of slurries,
Area 6, which is formed, in material plug forms the material with certain mass dryness fraction, frictional force increase between material and screen frame screen drum, when living load reaches
During to certain requiring, the bigger material plug of mass dryness fraction is formed, now, pneumatic cylinder action, drives a pair of back pressure disks to the two of screw spindle
Side is exited, and screen frame screen drum frictional force reaches balance to the thrust of material with helical blade, is formed Stabilizing Materials plug and stable and is gone out
Starch concentration.Pressure of the helical blade without additionally overcoming back pressure disk on screw spindle, total output load are greatly reduced.
