Technical field
The invention belongs to a kind of biomass processing components, and in particular to a kind of material extrusion wheel component with dustproof construction.
Background technique
Currently, the material extrusion wheel of all processing biological particles, is all to prevent dust from entering Bearing inner by oil sealing, due to
Material extrusion wheel works under conditions of high temperature, high pressure and bias, while can generate a large amount of dusts, and oil sealing is easily damaged, and dust enters
Bearing inner substantially reduces the service life of bearing and material extrusion wheel.
Summary of the invention
To prevent dust from entering oil sealing and Bearing inner, the deficiency for substantially reducing the service life of bearing and material extrusion wheel,
The present invention provides a kind of material extrusion wheel component with dustproof construction.
A kind of material extrusion wheel component with dustproof construction, including eccentric shaft, bearing cap, screw, material extrusion wheel, bearing, oil sealing, set
Cylinder, grease nipple and round nut.
It is machined with step in the upper end of material extrusion wheel, left-handed dustproof groove is machined on the periphery of step.
Sleeve is cased with outside dustproof groove, the gap at the top of the internal diameter and dustproof groove of preferred sleeve is 0.01-
0.05mm。
The section of preferred dustproof groove is rectangle, groove depth 1mm, groove width 2mm.
Dustproof groove effectively can prevent dust from entering in bearing, extend the service life of bearing, and that improves equipment uses the longevity
Life and production efficiency.
It is machined with step at the center of material extrusion wheel, upper and lower in step is equipped with bearing, and material extrusion wheel is existed with two bearing supports
On eccentric shaft.
It is screwed on material extrusion wheel equipped with oil sealing, bearing and oil sealing by bearing cap in the outside of bearing.
Centre at the top of sleeve is machined with circular hole, is threaded on eccentric shaft top, and eccentric shaft upper end is at the top of sleeve
Circular hole in stretch out, fixed with round nut.
It is connected with grease nipple in sleeve top outer, is machined with oil duct in the centre of eccentric shaft, grease nipple and oil duct are constituted
One lubricating loop.
The utility model has the advantages that
1, dust can be effectively prevent to enter Bearing inner, the service life of material extrusion wheel improves 2 times or more.
2, the working efficiency of material extrusion wheel improves 30%-50%.
