Abstract
The rotor and stator for beating equipment used in paper making is made up by combination of friction blocks in the form of prismatic body with metallic mother body, between them there are one or more join planes. The friction blocks made of hard alloy (or ceramic) may be welded to metallic mother body to obtain long service life and low cost.
Description
The present invention relates to papermaking equipment, particularly a kind of beating equipment for paper making rotor and stator.
The slurry treatment facility that is used for the paper industry pulping process at present mainly contains complete dissociation sand remover, bipyramid fluffer, fluted disc fluffer, disc mill etc., the critical piece of this kind equipment is rotor and a stator (claiming beater roll and bed plate again) of finishing pulp processing, and the life-span quality of rotor and stator directly determines the usefulness performance of whole slurry treatment facility.And present rotor and stator all adopt the whole machine-shaping of high-quality steel, behind quenching of tooth portion or nitrogen treatment, use, facts have proved that the premature wear that is tooth portion through the rotor and the stator structure of above-mentioned processed mode in operation damages more, service life is low, be generally 2-3 month, become the consumable accessory of whole making beating treatment facility, in use must change a whole set of rotor, stator, and can't repair utilization, waste a large amount of metal materials and processing charges, influence pulp production.For overcoming above-mentioned defective, stator, rotor in trough-style pulp beater, cylinder jordan and some conical disc mill pulp grinders, adopted blade has been embedded in frame mode on the roll body, inlay etc. as cement casting, hardwood, in use need only change blade, overcome the problem of bringing because of rotor, stator wearing and tearing to a certain extent, but this frame mode there is following defective: the one, insert blade process complexity, time-consuming; The 2nd, for guaranteeing to inlay working strength, blade size is bigger, and the metal material consumption is big, the use cost height; The 3rd, can only be applied on the big fiberizer in batch (-type) beater and roller thereof footpath, limited the scope of application of this frame mode, turn to relative certain at various slurry treatment facility rotors with stator, the characteristics that its tooth portion contact wear scope is fixing, designing a kind of new rotor and stator teeth structure has become possibility.
The objective of the invention is to design, make and a kind ofly can effectively improve rotor and stator service life, save manufactured materials consumption, use cost is low, and can be to rotor and the stator recycling because of tooth portion wear damage, rotor and stator with new tooth portion structure.
The present invention is achieved in that and is used for pulp processing equipment, rotor and stator with defibrination tooth, the tooth portion of rotor and stator is by the metal carrier body be combined into of the friction block of tool multiedge cylinder shape, between friction block and metal carrier body the one or more plane that combines is arranged, friction block can be straight tri-prismoid or straight four prisms cylinder, can be one between friction block and metal carrier body and combine the plane, the friction block material therefor is Hardmetal materials or ceramic material, available brazing or mosaic mode be combined between friction block and metal carrier body.
The present invention compared with prior art has following characteristics: the one, reduced manufacturing cost, and the processed expense can reduce more than 30%; The 2nd, reduced use cost, every equipment can reduce the consumable accessory expense more than 95% every year; and reduced the number of times of shutdown maintenance; the 3rd, the life-span increases substantially; can improve 12 times service life by existing rotor and stator; the 4th, can repair utilization again to decreasing rotor and stator; only need to change friction block, and make simple.
Now in conjunction with the accompanying drawings, enumeration embodiments of the invention: Fig. 1 is the partial sectional view of straight tri-prismoid friction block rotor, Fig. 2 is the partial sectional view of straight tri-prismoid friction block stator, and Fig. 3 is the partial top view of mill rotor, and Fig. 4 is the partial sectional view of straight tri-prismoid friction block mill rotor.1-friction block wherein, the 2-metal carrier body, 3-is in conjunction with the plane.
Friction block (1) is straight tri-prismoid and metal carrier body (2) be combined into, constitutes rotor and stator profile of tooth, has one to combine plane (2) between friction block (1) and metal carrier body (2).Friction block (1) adopts Hardmetal materials YG8, and adopts brazing to be welded between metal carrier body (2).
In actual manufacture process, can be earlier with metal carrier body (2) machine-shaping, by whole profile of tooth requirement processing friction block (1), friction block (1) and metal carrier body (2) are being welded into one with brazing in conjunction with plane (3) then, fixing profile of tooth at last reaches precision and gets final product, implementing other technologies of the present invention, to be those of ordinary skill of the same trade known, so do not give unnecessary details.
Claims (3)
1, a kind of rotor and stator that is used for having on the pulp beating equipment defibrination tooth.It is characterized in that friction block (1) and metal carrier body (2) be combined into of the tooth portion of described rotor and stator, between described friction block (1) and described metal carrier body (2) the one or more plane (3) that combines is arranged by tool multiedge cylinder shape.
2, by described rotor of claim 1 and stator, it is characterized in that described friction block (1) is straight tri-prismoid or straight four prisms cylinder, there is one to combine plane (3) between described friction block (1) and described metal carrier body (2).
3,, it is characterized in that described friction block (1) forms for adopting the brazing solder bond between Hardmetal materials or described friction block of ceramic material (1) and described metal carrier body (2) by claim 1 or 2 described rotor and stators.
