Abstract
The utility model discloses a novel rotor for a powder concentrator of a vertical mill. The novel rotor comprises a lower conical body, wherein a transmission shaft is arranged at the center part of the lower conical body; a blade ring is arranged on the lower conical body; the blade ring is formed by uniformly arranging blades at the periphery of the lower conical body; each blade is integrally formed by connecting an upper layer blade, a middle layer blade and a lower layer blade from top to bottom; a connection ring is arranged at the connection part of the two adjacent layer blades; a reinforcement ring is further arranged in the middle of the lower layer blade in a sleeving manner. For solving the problem that the blades of a rotor of the powder concentrator are broken, the utility model designs the rotor with the novel structure through the optimal design of the structure of the blades; a steel board reinforcement ring which is the same as the blades in thickness and width is additionally arranged in the middle height of the lower layer blade of the powder concentrator, so that the rigidity of the blades is improved; finally, the breakage problem of the blades can be solved.
Description
Technical field
The utility model belongs to roller mill separator parts, relates in particular to the rotor on a kind of roller mill separator.
Background technology
Powder concentrator is parts of Vertical Mill, is positioned at Vertical Mill top, to being carried out the separation of thickness powder by the material on gas band after the grinding of Vertical Mill bottom.In powder concentrator use procedure, lower leave repeatedly ruptures, and the safety that directly has a strong impact on vertical mill system runs well.Cement, electric power and steel industry are more and more used vertical mill grinding material, it is reported, in the use procedure of many producers, the rotor of powder separator vanes normal off of Vertical Mill splits, and has a strong impact on the normal operation of Vertical Mill.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency provides a kind of novel rotor of roller mill separator, solves the technical problem of leaf destruction, has eliminated the potential safety hazard that affects system operation.
For achieving the above object, the utility model is by the following technical solutions:
A kind of novel rotor of roller mill separator, comprise lower cone, lower cone centre is provided with power transmission shaft, on lower cone, be provided with blade ring, blade ring is evenly arranged in lower cone surrounding by blade and forms, described blade is connected as a single entity from top to bottom by upper strata blade, middle level blade and lower leave, is provided with connecting ring in the junction of adjacent layer blade, is also arranged with stiffening ring in the middle part of lower leave.
The novel rotor of above-mentioned roller mill separator, described stiffening ring is and the steel plate stiffening ring of the width such as blade equal thickness.
Adopt technique scheme, the utility model has following advantage: for solving rotor of powder separator leaf destruction problem, structure to blade is optimized design, design a kind of new structure rotor, in powder concentrator lower leave height middle part, add the steel plate stiffening ring wide with blade uniform thickness, improve the rigidity of blade, finally solve leaf destruction problem.
Accompanying drawing explanation
Fig. 1 is roller mill separator structural representation.
Fig. 2 is the novel structural representation of this family property.
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
The novel rotor of a kind of roller mill separator as shown in Figures 2 and 3, comprise lower cone 1, lower cone centre is provided with power transmission shaft 2, on lower cone, be provided with blade ring, blade ring is evenly arranged in lower cone surrounding by blade and forms, described blade is connected as a single entity from top to bottom by upper strata blade 5, middle level blade 4 and lower leave 3, be provided with connecting ring 6 in the junction of adjacent layer blade, middle part at lower leave 3 is also arranged with stiffening ring 7, and described stiffening ring 7 is and the steel plate stiffening ring of the width such as blade equal thickness.The thickness 10mm of stiffening ring, width 100mm, is welded on lower leave.
The utility model is for solving rotor of powder separator leaf destruction problem, structure to blade is optimized design, design a kind of new structure rotor (see figure 3): in powder concentrator lower leave height middle part, add steel plate stiffening ring (the thickness 10mm wide with blade uniform thickness, width 100mm), the rigidity that improves blade, finally solves leaf destruction problem.Stiffening ring material 16Mn, with the welding of THJ422 welding rod.Through above design and processing, use nearly time blade more than 1 year so far not rupture again, effect is fine.Fig. 1 is provided with roller mill separator of the present utility model.
