Abstract

The present invention discloses a refiner which comprises a first grinding disc, a second grinding disc and an intermediate grinding disc that rotate relatively. The intermediate grinding disc is installed between the first grinding disc and the second grinding disc. Tapered rollers are installed along the peripheral direction of the intermediate grinding disc on the grinding disc frame of the grinding disc. The small ends of the tapered rollers are inward. When the first grinding disc and the second grinding disc are dragged by a crankshaft to rotate relatively, the tapered rollers on the intermediate grinding disc must be driven to rotate. Thus the tapered rollers rotate and operate on the contact working surfaces of the grinding discs. On one hand, the refiner of the invention has the advantages of greatly reduced power consumption, reduced material damage, prolonged service lifetime and increased operating efficiency; and on the other hand, as many tapered rollers are provided, when the tapered rollers rotate and operate with a high speed, the material is crushed repeatedly by the tapered rollers which operate in high speed one after another once enters the refiner. Therefore the main grinding mode of the invention is grinding. The material is easily grinded uniformly and regularly. The length of the fiber is protected and the performance of the refiner according to the invention is remarkably reinforced compared with the prior grinder.

Description

Fiberizer

Technical field

The present invention relates to a kind of papermaking equipment, relate in particular to a kind of fiberizer.

Background technology

Existing fiberizer is divided according to the difference of its abrasive material workpiece shape, mainly comprises disc type, circular cone type and column type three major types.With the disc type is example, its abrasive material workpiece mainly comprises movable grinding disc and static cutting disk two big parts, when movable grinding disc is rotated by the arbor work of drawing, there are the very big sliding friction of resistance each other in movable grinding disc and static cutting disk, cause power consumption too high, cause the temperature rise of abrasive material workpiece too fast thus, spillage of material is serious, shorten service life, must often change renewal.For timely cooling, the grinding charge material also has to select water-cooled slurry for use, and operating efficiency is lower.And, because the interference of friction too far, movable grinding disc and static cutting disk contacting each other just can not be very tight, ground material just can only rely on the corner angle of its groove groove flank of tooth to shred, and in fact the stranding mill effect in the middle of the flank of tooth can only play miscellaneous function in default of the support of contact pressure.Therefore, the mode that grinds of existing fiberizer mainly is to cut mill, is difficult to evenly ground material fitly, and machine performance is difficult to strengthen.

Summary of the invention

The abrasive material workpiece too fast technical barrier of the excessive power consumption that causes of sliding friction spillage of material too high and that cause thus each other when solving existing fiberizer work running the invention provides a kind of in the hope of enhancing machine performance, the fiberizer of increasing work efficiency.

For solving the problems of the technologies described above, technical scheme of the present invention is: fiberizer, comprise first mill and second mill in relative rotation, and also comprise:

Middle mill is installed between described first mill and second mill, comprises the awl roller along middle mill circumferential arrangement, and the small end of described awl roller is inside;

The working surface of described first mill and second mill contacts with the awl roller of described middle mill.

As optimized technical scheme, described middle mill comprises millrind, and described awl roller circumferential arrangement is on described millrind.

As to improvement of the technical scheme, one in described first mill and second mill is movable grinding disc, and another is a static cutting disk.

As to improvement of the technical scheme, described first mill and second mill are two opposite movable grinding discs of direction of rotation.

As to improvement of the technical scheme, described in the middle of the millrind of mill fixedly install.

As to improvement of the technical scheme, described in the middle of the millrind of mill rotate and be provided with.

Owing to adopted technique scheme, when first mill and second mill are being drawn when relatively rotating by arbor, awl roller rotation in the middle of must driving on the mill, the awl roller running of just on the contact working face of mill, do rolling like this, first mill and second mill sliding friction between the two will be transformed between first mill, middle mill and the second mill three by boring the rolling friction of roller in the fiberizer so will have now; Can significantly reduce power consumption on the one hand, the lightening material loss increases the service life, and increases work efficiency; On the other hand; because awl roller One's name is legion; in case high speed scroll running; as long as material enters in the fiberizer; therefore the awl roller that will be run up one by one weight over and over again pulverizes, and main defibrination mode of the present invention is to mill, easily even ground material fitly; the protection fibre length, performance significantly strengthens than existing material grinder.

Fig. 2 is the front view of middle mill.

For the ease of observing, Fig. 1 is the drafting that spaces out of first mill, middle mill and second mill, and when real work, their threes mesh and contact very closely; The drawn arrow indication of Fig. 1 material traffic direction; Among the figure: the 1-arbor; 2-first mill; Mill in the middle of the 3-; 4-bores roller; The 5-millrind; 6-groove groove; 7-bores roll shaft; 8-discharging direction; The 9-charging aperture; 10-second mill.

The specific embodiment

As shown in Figure 1 and Figure 2, well-known components such as body and pressue device have been omitted among the figure.The fiberizer of present embodiment comprises first mill 2 and second mill 10 in relative rotation, first mill 2 is a movable grinding disc in the present embodiment, and by arbor 1 driven rotary, second mill 10 is a static cutting disk, the center of second mill 10 is provided with charging aperture 9, and the fiberizer of present embodiment also comprises:

Middle mill 3 is installed between described first mill 2 and second mill 10, comprises millrind 5, in the middle of described millrind 5 upper edges mill 3 12 awl rollers 4 circumferentially are installed, the small end of described awl roller 4 is inside; Described awl roller 4 circumferentially is distributed on the described millrind 5.

The working surface of described first mill 2 and second mill 10 closely contacts with described awl roller 4.

In the present embodiment, the millrind 5 of described middle mill 3 rotates and is provided with, and promptly described middle mill 3 is located by the clamping of described first mill 2 and second mill 10.

In the present embodiment, the working surface of the working surface of the working surface of described first mill 2, second mill 10, described awl roller 4 can be provided with groove groove 6, to increase refining effect, described groove groove 6 can be with respect to the axis of awl roller 4 vertical, horizontal, oblique or other grain direction arrange, the groove groove of mill and awl roller is in contact with one another cooperation.

The course of work of present embodiment is as follows: as seen from Figure 1, slurry enters the workspace of the abrasive material workpiece of being made up of second mill 10, middle mill 3 and first mill 2 from charging aperture 9.When arbor 1 did not rotate, slurry directly flowed away from discharging by the space between second mill 10, middle mill 3 and first mill, 2 threes.When arbor 1 traction first mill 2 rotates, mill 3 rotations in the middle of also driving, on the one hand slurry is played the effect of centrifugal pumping, but main one side is: because awl roller 4 One's name is legions, it is very fast to add the roll angular speed of running of epicone roller 4, so immediately slurry is placed under its brute force rolls, material had both made the past bore roller together and has been extruded out, also will drop into several awl roller of back at once and bear and mill for several times, and could arrive discharging opening after slurry is ground, thereby finish abrasive process.
