Embodiment Construction

[0016] like figure 1 , figure 2 As shown, well-known components such as the body and the pressurizing device are omitted in the figure. The refiner of this embodiment comprises a first grinding disc 2 and a second grinding disc 10 which rotate relatively. In this embodiment, the first grinding disc 2 is a moving grinding disc driven by the shaft 1 to rotate, the second grinding disc 10 is a static grinding disc, and the second grinding disc 10 is a static grinding disc. The center of the grinding disc 10 is provided with a feed inlet 9, and the refiner of the present embodiment also includes:

[0017] The middle grinding disc 3 is installed between the first grinding disc 2 and the second grinding disc 10, and includes a grinding disc frame 5, on which twelve tapered rollers 4 are installed along the circumference of the intermediate grinding disc 3, the cone The small ends of the rollers 4 are inward; the tapered rollers 4 are uniformly distributed on the disc frame 5 in t...

Abstract

The invention discloses a refiner, which comprises a first millstone, a second millstone and a middle millstone which rotate relative to each other, wherein the middle millstone is installed between the first millstone and the second millstone, cone rolls are installed on the racks of the millstones along the circumferential direction of the middle millstone, the small ends of the cone rolls are inwards; when the first millstone and the second millstone rotate relative to each other under the traction of a crankshaft, cone rolls on the middle millstone are driven to rotate, thus the cone rolls perform rolling operation on the contact work surface of the millstones; on one hand, power consumption can be significantly reduced, material consumption can be reduced, service life can be prolonged, and work efficiency is improved; on the other hand, due to the numerous cone rolls, once the cone rolls roll at a high speed to operate, a material can be pressed and crushed again and again successively by the cone rolls rotating at the high speed as long as entering the refiner, therefore, the mainly refining method of the invention is milling, the material is easy to be evenly and neatly milled, thus the fiber strength is protected and the performance of the refiner is significantly enhanced as compared with the existing grinder.

Description

technical field [0001] The invention relates to a papermaking machine, in particular to a refiner. Background technique [0002] Existing refiners are classified according to the shapes of their abrasive working parts, and mainly include three types: disc type, conical type and cylindrical type. Taking the disc type as an example, its abrasive working parts mainly include two major parts, a moving grinding disc and a static grinding disc. When the moving grinding disc is driven by the shaft to rotate, there is a sliding friction between the moving grinding disc and the static grinding disc with great resistance. As a result, the power consumption is too high, which causes the temperature rise of the abrasive working parts to be too fast, the material loss is serious, and the service life is shortened, so it must be replaced and updated frequently. In order to cool down in time, the material to be ground has to use water-cooled slurry, and the work efficiency is low. Moreov...
