Abstract
The utility model discloses a filter drum of a press machine, comprising a filter frame. The filter drum has the structural key point that the inner periphery of the filter frame is an annular body with variable diameter. The filter drum has the advantage that, as the inner periphery of the filter frame is formed by the annular body with variable diameter, the generation of cement ring can be prevented; meanwhile, the filter drum is provided with a resistance device on the inner cavity of the filter frame for breaking the possibly generated cement ring; therefore, a spiral press device of the filter drum can prevent the generation of the cement ring to the greatest extent.
Description
Technical field
The utility model relates to the filter drum of a kind of acroll press washer, particularly press master.
Background technology
Acroll press washer comprises extrusion spiral device, discharging control device, filter drum, advances to starch compositions such as bucket, cell body, tailstock and transmission device.Slurry is sent into acroll press washer by advancing the slurry bucket, during the propellers rotation, pushes slurry to extruded segment and slurry output end from the transportation section.Mutual extrusion between paper pulp, filter drum and the propellers three, slide mutually, and under the acting in conjunction of the counter-pressure of the spiral axial thrust of certain compression ratio and pulp control device, paper pulp is squeezed and the dehydration of peripherad filter drum.Existing filter drum, its structure is made of torus as shown in Figure 1, the filter drum of this structure, the periphery along filter drum produces the slurry ring easily when operation, has influenced the effect of shove on the one hand, excessive on the other hand pressure makes filter drum break easily, has shortened the service life of filter drum.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part and provides a kind of and avoid producing the slurry ring, improves the filter drum of the press master in filter drum service life.
The purpose of this utility model realizes by following approach.
A kind of filter drum of press master comprises filter frame, and its structural feature is: described filter frame inner peripheral surface is the annular solid of reducing.
Adopt the annular solid of reducing to constitute filter frame, the slurry in the filter drum can form negative pressure at the reducing place when motion like this, thereby anti-grout stop produces, and then the service life that can improve filter drum.
The reducing annular solid of described filter frame inner peripheral surface is to form by the circular arc of multistage different radii is tangent.
The circular arc of described different radii is made of the circular arc of two different radiis.
The circular arc of described two different radiis is by tangent forming of circle of justifying and be positioned at axle center part four same radius all around that is positioned at the filter drum axle center part.
The utility model also is
Described filter frame internal chamber wall is provided with drag devices.
Drag devices is set destroys the slurry ring that will produce.
Described drag devices is the projection of extending along the filter drum inner chamber.
Very simple and convenient of mode of projection is set on filter frame.
The projection of extending along the filter frame inner chamber or for being integral the formula structure with filter frame.
Described projection of extending towards the filter frame inner chamber be with filter frame be that activity removably connects.
Adopt dismountable projection and being connected of filter frame to be convenient to projection is safeguarded.Described dismountable connection or connect or be the latch connection for spiral.
Described projection or be the inner chamber that is distributed in filter frame of point-like, or for being the inner chamber that is distributed in filter frame of strip.
In sum, the utility model has following advantage compared to existing technology:
This practicality newly by the transformation to the acroll press washer filter drum, makes the filter frame inner chamber be made of the circular arc of multistage different radii, thereby can prevent the generation of grout stop; Simultaneously the utility model is also by being provided with drag devices on the filter frame internal chamber wall, and destroying issuable slurry ring, thereby spiral shove device of the present utility model can hinder the generation of grout stop to greatest extent.

The specific embodiment
Below in conjunction with embodiment the utility model is described in more detail.
A kind of structural representation of acroll press washer as shown in Figure 1, 2, comprise filter frame 1 and drag devices 2, described filter frame is made of the circular arc of two different radiis, and it is by tangent the forming of circle of justifying and be positioned at axle center part four same radius all around that is positioned at the filter drum axle center part.Described drag devices is served as reasons and is arranged at the projection formation along the extension of Hu drum inner chamber at filter frame two symmetric position places.Be dismountable the connection between described projection and the filter frame, adopt latch to connect between them.
It is same as the prior art that present embodiment is not stated part.
