Abstract
A deflaker plate for use in a deflaker for reducing fibrous flakes in a slurry of fibers. The deflaker plate may include at least one annular ring consisting of multiple teeth, in which at least one tooth has a leading face, a trailing face, and an impact-generating side-face. The impact-generating side-face may be adapted to generate an impact force during operation, such that the force corresponds to a first vector radially pushing the slurry towards a center of the deflaker and a second vector tangentially pushing the slurry towards the leading face.
Claims16
A deflaker plate for use in a deflaker for reducing fibrous flakes in a slurry of fibers, the deflaker plate comprising:
- at least one annular ring consisting of multiple teeth,
- the at least one annular ring comprising at least one tooth having a leading face, a trailing face, and an impact-generating side-face, wherein the at least one tooth has a base portion supporting the at least one tooth on the deflaker plate so as to increase the durability or stability of the at least one tooth, the base portion being substantially cubic, and
- wherein the impact-generating side-face is adapted to generate an impact force having a first force vector radially pushing the slurry towards a center of the deflaker and a second force vector tangentially pushing the slurry towards the leading face.
A complementary set of deflaker plates for use in a deflaker for reducing fibrous flakes in a slurry of fibers, the complementary set of deflaker plates comprising:
- a rotor deflaker plate and a stator deflaker plate, wherein the rotor deflaker plate and the stator deflaker plate each comprise at least one annular ring consisting of multiple teeth,
- wherein the at least one annular ring of at least one of the rotor deflaker plate and the stator deflaker plate comprises at least one tooth having a leading face, a trailing face, and an impact-generating side-face, wherein the at least one tooth has a base portion supporting the at least one tooth on the deflaker plate so as to increase the durability or stability of the at least one tooth, the base portion being substantially cubic,
- wherein the impact-generating side-face is adapted to generate an impact force having a first force vector radially pushing the slurry towards a center of the deflaker and a second force vector tangentially pushing the slurry towards the leading face,
- wherein a gap is defined between the rotor deflaker plate and the stator deflaker plate when the rotor deflaker plate and the stator deflaker plate are mounted in the deflaker, and
- wherein the gap has a gap distance of 5.0 mm or less.
A deflaker plate for use in a deflaker for reducing fibrous flakes in a slurry of fibers, the deflaker plate comprising:
- at least one annular ring consisting of multiple teeth,
- the at least one annular ring comprising at least one tooth having a leading face, a trailing face, and an impact-generating side-face, wherein the top surface of the at least one tooth is not substantially planar, and
- wherein the impact-generating side-face is adapted to generate an impact force having a first force vector radially pushing the slurry towards a center of the deflaker and a second force vector tangentially pushing the slurry towards the leading face.
A deflaker plate for use in a deflaker for reducing fibrous flakes in a slurry of fibers, the deflaker plate comprising:
- at least one annular ring consisting of multiple teeth,
- the at least one annular ring comprising at least one tooth having a leading face, a trailing face, and an impact-generating side-face,
- wherein the impact-generating side-face is adapted to generate an impact force having a first force vector radially pushing the slurry towards a center of the deflaker and a second force vector tangentially pushing the slurry towards the leading face, and wherein the impact generating side face comprises a first portion adjacent to leading face, a third portion adjacent trailing face, and second portion adjacent the first and third portions, and wherein the first and third portions are substantially planar along the edges of the leading face and the trailing face, and wherein the second portion comprises a carved out portion from the plane defined by the first and third portions.
