Description
Technical field
The utility model belongs to screening machine field, particularly relates to a kind of metallurgical briquetting roller type sieving machine.
Background technology
Metallurgical briquetting screening machine belongs to roller type sifting equipment, its operation principle by top belt conveyer, the pelletizing that disc balling machine is produced is delivered to the top of roller type sieving machine, through the rotation of roller, pelletizing is made great-jump-forward and is advanced on roller, due to the gap effect between roller, pelletizing is sorted out with different diameters.
Will there be a constant value in the gap of roller type sieving machine roller according to technological requirement, along with technological requirement and the wearing and tearing of rod working time, gap between roller will often carry out adjusting and change the roller damaged, qualified to ensure the granularity of pelletizing, in pelletizing system, the fault rate of roll screen accounts for about 5%, in order to ensure normal production, when often needing adjustment roll screen gap and change roller operation, the time that reach is short, replacing is convenient, size requirement accurately.
But the sieve roller of existing roller type sieving machine and the many employings of motor are bolted on girder, because roller gap adjustment needs to adjust all rollers, so adjustment is very difficult, the adjustment of roller is conveniently sieved by present manufacturer, fixing lower margin hole many employings rectangular opening or rectangle elongated hole, wherein rectangular opening can not meet adjustment when requiring, also need to carry out scene and cut system, and rectangle elongated hole easily causes girder intensity not enough, and then the equipment of generation runs jitter phenomenon, rectangle elongated hole also easily causes the out-of-flatness of girder face in addition, mounted motor and roller misalign, also equipment can be caused to run the problem of shake.
Summary of the invention
The purpose of this utility model is to provide a kind of roller type sieving machine, solves existing roller type sieving machine screening low precision, and roller type sieving machine sieves the adjustment of roller or replacing construction is long, precision is poor, the problem of effort of taking a lot of work.
For achieving the above object, the technical solution of the utility model is: a kind of roller type sieving machine, is arranged on below pelletizer discharging belt conveyer, comprises frame, large ball roll screen, qualified roll screen, wide belt feeder,
Described large ball roll screen is fixed on frame front by support, is obliquely arranged in below pelletizer discharging belt conveyer, for tentatively screening out the excessive pelletizing of particle;
Described wide belt feeder is fixed on frame front by support, is arranged in parallel in immediately below large ball roll screen, for transporting the pelletizing that large ball roll screen filters out;
Described qualified roll screen is fixed on frame rear portion by support, is installed on below wide belt feeder discharging opening, for screening pelletizing further;
The sieve roller gap of described large ball roll screen is greater than the sieve roller gap of qualified roll screen.
Described large ball roll screen and qualified roll screen are made up of rectangular frame, some sieve roll assemblies, and described rectangular frame is made up of two girders and two side bars, described girder is provided with some T-shaped holddown grooves, for fixed electrical machinery and sieve roller; Sieve roll assembly is connected to form successively by motor, shaft coupling, sieve roller, and described sieve roller is fixed on the T-shaped holddown groove of girder of rectangular frame by the bearing holder (housing, cover) of a convex eaves of band.
Roller type sieving machine of the present utility model, mainly classifies the pelletizing that disc balling machine is produced according to production necessary requirement, and is screened out by the defective pelletizing being less than technological requirement and being greater than technological requirement, qualified pelletizing is delivered to follow-up producing process.The utility model has carried out new design to large ball roll screen and qualified roll screen simultaneously, lower margin hole is not used to fix, and T-shaped holddown groove is set on the rectangular frame girder of large ball sieve roller and qualified sieve roller, and the bearing holder (housing, cover) of a convex eaves of band is set, convex eaves is placed in T-shaped holddown groove, for spacing, and be fixed on girder by two stay bolts, adopt said structure, the position of adjustment sieve roller that can be fast and simple, avoids the shortcoming that present roller type sieving machine adopts rectangular opening and rectangle elongated hole to regulate roll screen to bring.

Fig. 3 is the convex eaves of the utility model bearing holder (housing, cover) and erection of main beam schematic diagram.
Detailed description of the invention
As shown in Figure 1, 2, 3, a kind of roller type sieving machine, is arranged on below pelletizer discharging belt conveyer, comprises frame 1, large ball roll screen 2, qualified roll screen 3, wide belt feeder 4,
Large ball roll screen 2 adopts the roller of Φ 120 × 2800mm, gap≤16mm, is made up of 21 rollers, is fixed on frame 1 anterior by support, is obliquely arranged in below pelletizer discharging belt conveyer, for tentatively screening out the excessive pelletizing of particle;
It is anterior that wide belt feeder 4 is fixed on frame 1 by support, is arranged in parallel in immediately below large ball roll screen 2, for transporting the pelletizing that large ball roll screen filters out;
Qualified roll screen 3 adopts the roller of Φ 120 × 2800mm, gap >=9mm, is made up of 37 rollers, is fixed on frame 1 rear portion by support, is installed on below wide belt feeder discharging opening, for screening pelletizing further;
The sieve roller gap of large ball roll screen 2 is greater than the sieve roller gap of qualified roll screen 3.
Large ball roll screen 2 and qualified roll screen 3 are made up of rectangular frame, some sieve roll assemblies, and rectangular frame is made up of two girders and two side bars, girder is provided with some T-shaped holddown grooves 5; Sieve roll assembly is connected to form successively by motor 6, shaft coupling 7, sieve roller 8, and motor 6 is fixed on the girder of rectangular frame, and sieve roller 8 is fixed on the girder of rectangular frame by the bearing holder (housing, cover) of a convex eaves 9 of band.T-shaped holddown groove 5 coordinates with the convex eaves 8 of bearing holder (housing, cover), motor set bolt respectively.
During use, the pelletizing being greater than 16mm that pelletizer is produced first screens out by large ball roll screen, the pelletizing being less than 16mm is fallen on wide belt feeder by roll screen gap, be transported on qualified ball screening machine by wide belt feeder again, the screening of ECDC diagrid extension set, be less than the fine ore of 9mm and pelletizing to fall in the lower funnel of sieve and carry out returning mine process, the drying grate sent by the pelletizing of 9-16mm carries out lower operation processing.
The adjustment of roll screen, first unclamp fixed length bolt, then in sliding motor or the position of sieving roller, then be fixed, owing to have employed the structure of T-shaped holddown groove, T-shaped holddown groove solve existing length rectangular opening on the restriction of sieve roller movement and the impact on girder panel stability.
