Definitions
- the invention relates to a rotor for a pulper one
- a pulp preparation plant which is arranged to circulate a pulp suspension contained in a container in this container and sweeps over a screen surface of the container, wherein the rotor is formed by a rotor head on which a plurality of rotor blades are attached to the outer periphery. Pulpers of this kind are mainly applied to dried ones
- Pulp or waste paper in suspension They exist in
- a container for the suspension and at least one rotor Essentially from a container for the suspension and at least one rotor.
- the registered material is intensively mixed in large pieces, webs or pressed bales with water, whereby a hydraulic material drive is generated by the rotor. Understandably, such devices are optimized, aiming essentially for a fast and efficient dissolution.
- the rotor is placed in close proximity to a flat screen that keeps it free of blockages. Through the openings of the screen, the dissolved substance is withdrawn as a suspension.
- the standard type for a pulper is a vertical cylindrical container with a rotor in the bottom area.
- water and the material to be dissolved is added from the top and with the help of the rotor creates a Trombenströmung in the suspension, ie in the inner region of the fabric is pulled down from the rotor and pressed radially outward in the bottom region, resulting in a Umtriebsströmung results.
- the object of the invention is therefore to improve the effectiveness of the rotors.
- this object is achieved in that the rotor blades starting from the screen surface have a different height. While the flat rotor blades provide strong shear in the screen area and keep the screen clear, the high rotor blades are designed to increase the flow of motions.
- Rotation direction on a high rotor blade followed by a low rotor blade Furthermore, it is advantageous if six rotor blades are attached to the rotor head.
- the rotor head has a relatively large diameter. Smaller rotor heads are energetically more efficient, but also susceptible to the formation of unresolved
- Pulp boards that lay over the rotor head and inside the rotor blades As a result, the effect of the rotor is greatly impaired.
- the pulp plates can even lead to the collapse of the Umtriebs in the container.
- the large rotor head leads to a large distance between the rotor blades in the area of the rotor head, so that large bale fragments have a lot of space and do not disturb the flow in the rotor.
- the side pointing in the direction of rotation of several, preferably all rotor blades is inclined starting from the screen surface in the direction of rotation. In combination with the large gap between the rotor blades, this ensures a good degree of filling of the wing interstices and thus a high efficiency of the rotor.
- the flow formation can also be supported by a curved shape of the rotor blades.
- Rotor head and the swept by the rotor blades rotor circuit forms an angle which differ by a maximum of 10 °, preferably at most 5 ° from each other.
- wegzuschleudern should be mounted on the rotor head at least one additional wing, which preferably extends within the outer periphery of the rotor head and is arranged asymmetrically to the rotor blades.
- the rotor is used in pulp dissolution.
- the invention will be explained in more detail with reference to an exemplary embodiment.
- the attached drawing shows:
- Figure 1 a schematic cross section through a pulper
- Figure 2 a plan view of the rotor 1
- FIG. 3 an overall view of the rotor 1.
- One embodiment of a pulper to which the invention can be applied is the standing, cylindrical and open top pulper according to FIG. 1, in which the screen and rotor 1 are located in the bottom region.
- the finished, pumpable pulp suspension 3 is characterized by the
- the rotor 1 is provided with a total of six curved rotor blades 6.7 and is driven in rotation in the direction of rotation 8 during operation of the pulper.
- the rotor 1 interacts with the screen surface 4.
- the corresponding sieve is mounted as close as possible to the underside of the rotor 1. This small distance is advantageously a few millimeters and causes a good resolution and the freedom of the sieve openings
- Sieve surface 4 the sieve on the rotor 1 side facing also provided with strips, which advantageously enhances the dissolving effect.
- the distance between the rotor 1 and the top of the bar is essential.
- the rotor 1 shown in detail in Figures 2 and 3 is particularly suitable for pulp suspensions 1 with high consistency in the range between 2 and 6%.
- the rotor 1 has a relatively large rotor head 5 with a diameter 10, on the outer circumference 15 of which the six rotor blades 6, 7 are fastened.
- the large rotor head 5 the formation of unresolved pulp plates can be effectively countered.
- the rotor blades 6, 7 have different heights perpendicular to the screen surface 4, with a lower rotor blade 6 following in the direction of rotation 8 onto a high rotor blade 7.
- Direction of rotation 8 inclined, which produces a flow component to the screen surface 4.
- the high rotor blades have a 7 in
- an additional wing 9 which extends within the outer periphery 15 of the rotor head 5 and is arranged asymmetrically to the rotor blades 6.7.
