Abstract
The invention relates to a universal gate transition region millstone which is applied to a fiber production link in a production process of an artificial board. The universal gate transition region millstone is divided into four regions, that is to say a 'fracture region', a 'coarse grinding region', a 'universal gate transition region' and a 'fine grinding region', wherein the 'coarse grinding region' and the 'fine grinding region' are mutually connected by using the 'universal gate transition region'; and wood chips after being grinded in the coarse grinding region are ensured to freely and uniformly distribute to the fine grinding region from the 'universal gate transition region' and then are grinded into fine fibers in the fine grinding region. According to the invention, even if how more, how faster in an entrance, the wood chips are all redistributed in the universal gate transition region before entering the fine grinding region so that the work load of the fine grinding region is allowed to be uniformly distributed on the entire circumferential direction, the effect of rational space utilization is realized, the fiber uniformity degree and the state stability are ensured; in addition, materials in the fine grinding region are ensured to fill the space of the entire millstone so that all space of the entire millstone is fully used so as to achieve the effects of saving power consumption, increasing efficiency and improving fiber quality.
Description
Technical field: the present invention is used in the wood-based plate industry production process of lumber fibre;
Background technology: in the production process of beaver board, the production of fiber is the vital link of product (beaver board) quality, it also is the part of electric consumption maximum in the middle of the whole production line, so production efficiency of mill, paid close attention to by all producers service life, the mill of all manufacturer production all is a kind of form now, that is exactly a timber from entering mill all is to move ahead along " unique passage " to going out mill, and mill is circular, work area mill circle centre position minimum, enlarge to circumferencial direction, wood chip is to enter to the motion of external diameter direction from circle centre position to be worn into fiber, i.e. inlet " little " outlet " greatly ", if guarantee quality of fiber efficient is reduced, waste of energy is serious, if increase the speed of charging, quality of fiber will descend so, I can solve the contradiction of this speed and quality through having invented this universal door transition region mill after repeatedly practising like this.
Summary of the invention: each mill is combined into circular could the use by several abrasive discs.I invent this universal door transition region mill four districts, promptly " fracture area ", " corase grind district ", " universal door transition region is " with " correct grinding district ".Between corase grind district and correct grinding district, link to each other, guarantee the wood chip that grind from the corase grind district with " universal door transition region ", free from " universal door transition region ", be distributed to the correct grinding district uniformly, wear into fine fibre by finish grinding to distinguish again.Even Ru Kou wood chip is many more like this, fast again, entering before the correct grinding district, all can redistribute in transition region, allow correct grinding district live load on the whole circumference direction, be evenly distributed, reach the effect of rationally utilizing the space, guarantee the uniformity coefficient of fiber and the stability of state.The material that also can guarantee simultaneously to finish grind the district can be full of the space of whole mill, and the institute that makes full use of whole mill has living space, and reaches the effect of saving power consumption, raising the efficiency, improving fiber quality.
Description of drawings: Fig. 1 is the A-A profile, is combined by a plurality of abrasive discs, is the structure under in running order
Fig. 2 is the working state schematic representation of mill
Fig. 3 is the various piece purposes of single abrasive disc when work
Fig. 4 is the B-B profile
Fig. 5 is the C-C profile
Among the figure 1, mill 2, stationary disk holder; 3, static mill; 4, the mill of Zhuan Donging; 5, the holder of rolling disc; 6, wood chip; 7 crude fibres; 8, fine fibre; 9, vapours; 10, correct grinding district; 11, corase grind district; 12, fracture area, 13, groove; 14, abrasive material bar; 15, universal door transition region;
The specific embodiment: as shown in Figure 2, wood chip (6) enters under the pressure of vapours (9) in the middle space of two abrasive discs, and wood chip is subjected to static abrasive disc (3) and rotates meticulous, the uniform fibers that is ground to of abrasive disc (4).As shown in Figure 3, wood chip (6) enters corase grind district (11) and is worn into crude fibre (7) after fracture area (12) is broken, is evenly distributed to correct grinding district (10) in universal door transition region (15) then and wears into meticulous uniform fibers.
Claims (2)
1. universal door transition region mill, it is characterized in that: the multi-disc group is arranged and become disc to be called one group, per two groups are used simultaneously, one group of static another group rotation, timber in the middle of two groups of mills is worn into fiber, and each group mill all is made up of fracture area, corase grind district, universal door transition region and correct grinding district.
2. according to claim 1, universal door transition region is characterized in that: universal door transition region is a downward sunk annular section, and the height in corase grind district and correct grinding district substantially in one plane, promptly has the ring plain annular region of a depression coupled at thick, correct grinding between the district.
