Description
Technical field
The present invention relates to solid-liquid separating machine technical field, specially a kind of screw extruding type solid-liquid separator auger.
Background technique
Screw extruding type solid-liquid separator is made of body, mesh screen, extruding auger, counterweight, discharge duct etc., the course of work
Are as follows: unleavened liquid dung is pumped into body by Non-blinding pump, is accelerated blanking under the action of vibrating motor, is passed at this time through power
It is dynamic, it squeezes auger and gradually pushes liquid dung in front of body, while up-front pressure is continuously improved, force the moisture in material on side
Mesh screen is squeezed out under the action of pressure zone filter, flows out drainpipe.
By above-mentioned technical process determine filter-press type seperator extruding auger front end blade can with squeeze work into
Row and gradually by very big axial compression power, and the trailing vane for squeezing auger is then very small by axial reaction force, as a result,
The damageable zone of packing auger blade also is located at front end, for the service life for protecting packing auger blade, i.e., to reinforce the production of packing auger blade
Technique reduces forward ends thereof power (what i.e. reduction filter-press type was separated by solid-liquid separation goes water), both above-mentioned mode, or improves auger
Technique and use cost, or the result and subsequent dry treatment process cost that are separated by solid-liquid separation are influenced, for this purpose, proposing that one kind changes
Auger is squeezed into type, it is intended to be solved the above problems.
Summary of the invention
It is deposited in use for the extruding auger of the existing screw extruding type solid-liquid separator proposed in background technique
Deficiency, the present invention provides a kind of screw extruding type solid-liquid separator auger, have crush resistance strength it is higher, using the longevity
More long advantage is ordered, solves the problems mentioned above in the background art.
The invention provides the following technical scheme: a kind of screw extruding type solid-liquid separator auger, including hinge shaft and fixation
The spiral strand leaf being socketed on outside hinge shaft, the front end of the hinge shaft and the endface position for being located at spiral strand leaf are equipped with bearing mechanism,
The end fitting spiral of the bearing mechanism twists the end convolution face of leaf, and the side surface of the bearing mechanism is tapered surface, described
Bearing mechanism is made of preceding pressure-bearing set and rear pressure-bearing set, and one end of the preceding pressure-bearing set and rear pressure-bearing set twists the end of leaf with spiral

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of screw extruding type solid-liquid separator auger referring to FIG. 1-2, including hinge shaft 1 and it is fixedly sheathed in hinge shaft 1
External spiral twists leaf 2, is equipped with bearing mechanism 3 at the front end position of hinge shaft 1, the end fitting spiral of bearing mechanism 3 twists 2 spiral shell of leaf
Radial facing, the side surface of bearing mechanism 3 are tapered surface, and bearing mechanism 3 covers 3a by preceding pressure-bearing and rear pressure-bearing set 3b two parts form, preceding
The end convolution face paste that one end that pressure-bearing covers 3a and rear pressure-bearing set 3b twists leaf 2 with spiral is closed, preceding pressure-bearing set 3a and rear pressure-bearing set
3b passes through the outside that shear studs 4 are fixedly installed in hinge shaft 1 respectively, and preceding pressure-bearing set 3a and rear pressure-bearing set 3b contact side pass through fastening
Bolt 5 is connected to one.
The setting of bearing mechanism 3 as a result, is substantially that the end for twisting leaf 2 in spiral transform helical blade as solid spiral
Tapered surface, and one week spiral is only carried out, at the starting of bearing mechanism 3 and terminating point, there are open channels to realize material
Spiral release, preceding pressure-bearing set 3a and rear pressure-bearing set 3b pass through the outside that two shear studs 4 are fixedly installed in hinge shaft 1 respectively,
And be also fixedly connected by fastening bolt 5 between preceding pressure-bearing set 3a and rear pressure-bearing set 3b, thus, guaranteeing that material still is able to push away
During, directly acted on bearing mechanism 3 so that the end that spiral twists leaf 2 squeezes reaction force, and by shear studs 4
Play the role of main pressure-bearing, twists the axial reaction force bring that 2 end of leaf is subject to so as to largely be sustained spiral
Unfavorable Moment preferably protects spiral to twist leaf 2, improves the service life that spiral twists leaf 2.On the other hand, bearing mechanism 3
Conical surface can not only play the role of promoting material, and side perpendicular to tapered surface can also will be shared by axial force
To, the pushing direction of pressing materials is become from axial to cylinder inner wall, i.e., the promotion of original material axially squeezes, present
Material promotion is squeezed along diagonally forward, is further decreased reaction force and is brought the moment of flexure of bearing mechanism 3, while efficiently using barrel
Pressing mechanism is formed, filters pressing effect is preferably reached.In addition, the bearing mechanism 3 that end adds, can reduce spiral and twist leaf 2 and body
Reserved space between front end can reduce in the final stage of single extrusion operation and remain on the intracorporal solid material of machine, be convenient for
Prune job.
Wherein, the free end of preceding pressure-bearing set 3a and rear pressure-bearing set 3b are set as concave arc surface, on the one hand which is
It properly increases the material reserved between preceding pressure-bearing set 3a and rear pressure-bearing set 3b and gets into channel space, on the other hand, be convenient for object
Material is released in front of side in the form of spiral squeezing, forms pressing mechanism with barrel.
Wherein, preceding pressure-bearing covers 3a and cast iron is respectively adopted by rear pressure-bearing set 3b and cast aluminium is made, and its volume fraction is 1:3.
After being fixedly mounted outside hinge shaft 1 in view of solid object block, the fixed-axis rotation of hinge shaft 1 generates unfavorable vibration there are eccentric part
It is dynamic, the stability of equipment operation is influenced, so cast iron and casting is respectively adopted according to volume accounting in two parts of bearing mechanism 3
Aluminium, to reach the symmetrical sexual balance of quality, so that installing the hinge shaft 1 after bearing mechanism 3 additional reaches dynamic balancing in rotation.
Wherein, the end of shear studs 4 and fastening bolt 5 is all made of interior screw socket and is located at the table of bearing mechanism 3 after twisting admittedly
In face, in order to the installation and replacement of bearing mechanism 3, meanwhile, reduce resistance when squeezing rotation.
