Abstract
The invention discloses a pulping machine barrel. The pulping machine barrel is characterized in that two semicircular barrel parts are assembled in an aligned mode to form the circular barrel, and the barrel parts are integrally cast to form the circular barrel. The two barrel parts are formed by casting through an identical casting mold, dimensions are consistent, welding deformation is avoided by integral casting forming of a reinforcing rib, an installing platform and the barrel parts, the barrel can be formed by good alignment, the barrel formed after alignment is in a regular circular shape, and work of a fixed grinding slice installed in the barrel is not influenced. The barrel parts are integrally cast, deformation is small, process steps are simplified, the precision requirements after fixed grinding slice assembly can be guaranteed, the fixed grinding slice and a movable grinding slice can move in a well matched mode to perform pulping, pulping quality is improved, and the service life of the pulping machine is prolonged.
Description
Technical field
The present invention relates to a kind of fiberizer, relate in particular to a kind of fiberizer cylindrical shell, belong to the paper making equipment technical field.
Background technology
Be assembled with in the fiberizer cylindrical shell and decide abrasive disc, by the relative motion of deciding abrasive disc and its inner moving abrasive disc material is carried out defibrination.The fiberizer cylindrical shell is decided abrasive disc because of needs, therefore, its processing technology is had relatively high expectations, at present, what the fiberizer cylindrical shell adopted is the welding structure, and it is many to add the man-hour processing step, the distortion that welding produces is larger, cause decide abrasive disc difficulty is installed or install decide abrasive disc after, it is different from the gap between the moving abrasive disc to decide abrasive disc, affects defibrination quality and fiberizer service life.
Summary of the invention
Technical problem to be solved by this invention is to overcome defective of the prior art, and a kind of fiberizer cylindrical shell is provided, and deflection is little, does not affect assembling and decides abrasive disc.
For solving the problems of the technologies described above, the invention provides a kind of fiberizer cylindrical shell, it is characterized in that assemble a torus cylindrical shell by the cylindrical shell spare of two semi-circular ring shapes is involutory, described cylindrical shell spare monoblock cast forms.
Described cylindrical shell spare outer surface is cast with integrated reinforcement.
Described cylindrical shell spare inner surface is cast with integrated a plurality of mounting platform.
Be cast with the installation through hole on the described cylindrical shell spare.
Two axial edges of described cylindrical shell spare are involutory edge, described involutory along on be provided with a plurality of assembly holes, be assembled into cylindrical shell by described assembly hole after two cylindrical shell spares close up.
The beneficial effect that the present invention reaches:
Fiberizer cylindrical shell of the present invention, two cylindrical shell spares are formed by same mold casting, consistent size, welding deformation has been avoided in reinforcement, mounting platform and the moulding of cylindrical shell spare integrally casting, can be good be combined to form cylindrical shell, the cylindrical shell that makes involutory rear formation is the annular of a rule, does not affect its inner abrasive disc work of deciding of installing.Cylindrical shell spare is monoblock cast, and deflection is little, and processing step is simplified, and can guarantee to assemble the required precision of deciding behind the abrasive disc, makes to decide between abrasive disc and the moving abrasive disc well that routing motion carries out defibrination, has improved defibrination quality and fiberizer service life.
Description of drawings
Fig. 1 is fiberizer cylindrical shell spare schematic diagram;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is two cylindrical shells after the combination of cylindrical shell spare.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1 and Figure 2, that fiberizer cylindrical shell spare 1 is the schematic diagram of half cylindrical shell, 1 monoblock cast of this cylindrical shell spare forms, and is semi-circular ring, and is cast with installation through hole 11, be used for installing and decide abrasive disc, outer surface 12 is cast with integrated reinforcement 14, and inner surface 13 is cast with integrated a plurality of mounting platform 15, has good flatness, be used for and decide abrasive disc and fit, make and decide abrasive disc and fix.
Two axial edges of cylindrical shell spare 1 are involutory along 16 with the plane interface, involutoryly can consist of a complete torus along being provided with on 16 after 17, two cylindrical shell spares 1 of a plurality of assembly holes close up, and are assembled into cylindrical shell 100 by assembly hole, as shown in Figure 3.
Two cylindrical shell spares 1 are formed by same mold casting, consistent size, reinforcement 14, mounting platform 15 have been avoided welding deformation with the 1 integrally casting moulding of cylindrical shell spare, can be good be combined to form cylindrical shell 100, making the cylindrical shell 100 of involutory rear formation is the annular of a rule, does not affect its inner abrasive disc work of deciding of installing.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
