Description
Affiliated technical field
The present invention relates to a kind of novel open coal mine processing Crushing Station that mines raw coal, specifically a kind of semi-fixed type Crushing Station.
Background technology
Domestic and international increasing open coal mine adopts the semicontinuous production technology of monobucket-truck-Crushing Station-ribbon conveyer, and raw coal is reprinted and the mobile of Crushing Station is the key technology of half-continuous process.Fixed Crushing Station cost is high, and Crushing Station can't fast moving, and along with the exploitation of opencut, the truck transport distance is more and more longer, and operating cost is high; The external single roller toothed plate type feed or the Movable Crushing Station of scraper plate machine feed can realize frequent moving, and it is convenient to lay; But Cracking Mechanism is an impact type; Grade influence to raw coal processing is bigger, influences the washing and the recovery of raw coal, and single cover ability of present domestic use is 1500t/h to the maximum; The arrangement form of the semi-fixed type Crushing Station that domestic opencut adopts is scraper plate machine feed+steel hopper+double-geared roller crusher, this semi-fixed type Crushing Station, and working ability is big, moves and establishes simply, at present wide popularization and application.But in application, there is following technological deficiency:
The scraper plate machine can not be realized " drawing " coal effect, and coal seam thickness is high in the scraper plate machine, under the certain situation of speed, causes down-stream system processing, conveying capacity to strengthen, otherwise overload;
When the scraper plate machine was scraped material, the raw coal in the hopper is whole to be moved, and can not start when causing the heavy duty of system overload or scraper plate machine;
The material feeding of scraper plate machine horizontal segment, tilting section promotes transportation, and the scraper plate machine is that varied angle arranges that running resistance is big, and fault rate is high;
Operating room is arranged on the broken platform, vibrate bigger, to the influence of automatically controlled facility big with the physical and mental health that has a strong impact on operating personnel;
This semi-fixed type Crushing Station is moved and is established module and be provided with unreasonablely, and individual modules is excessive, moves and establishes inconvenience.
Summary of the invention
Technical problem to be solved by this invention is to overcome the prior art defective that above-mentioned this kind semi-fixed type Crushing Station exists, provide a kind of reliable, move and establish semi-fixed type Crushing Station easily.
The technical solution adopted for the present invention to solve the technical problems is: a kind of semi-fixed type Crushing Station mainly is made up of scraper plate machine, the high device of scraper plate machine material feeding section coal ductility limit, double-geared roller crusher, disintegrating machine support platform, operating room, phase transformation and switchgear house etc.; Double-geared roller crusher is arranged on the discharge ribbon conveyer, and the scraper plate machine head is installed in the top of feed of crusher mouth, and scraper plate machine head discharge height can the scraper plate machine promotes the length of transportation section cell body and the inclination angle of adjusting scraper plate machine meets the demands through regulating.
Disintegrating machine support platform, scraper plate machine support, operating room support are separate, do not connect each other, avoid vibration interference and resonance influence, reduce dismounting and the installing engineering amount when establishing of moving;
Scraper plate machine, double-geared roller crusher are fixed by bolts to respectively on disintegrating machine support platform, the scraper plate machine support; Lean on alignment pin and high-strength bolt to fix between the cell body of scraper plate machine, the cell body both sides are provided with to draw and move ear simultaneously.
The scraper plate machine is in tilted layout; The inclination angle is 5 °～11 °, changes the horizontal material feeding section that has semi-fixed type Crushing Station scraper plate machine now into inclination material feeding section, and scraper plate machine material feeding section is same inclination angle with promoting the transportation section; The existing semi-fixed type Crushing Station scraper plate machine varied angle changeover portion of cancellation; The coal that truck ships is discharged on the tilting section of scraper plate machine drive end unit, thereby improves the service life of scraper plate machine, reduces the operation power consumption.
Scraper plate machine material feeding section is installed the facility of restriction coal stream height, realizes " drawing " coal effect, guarantees that the height of coal stream in the scraper plate machine promotes the transportation section is 400～700mm; Reduce simultaneously and receive the normal pressure of the interior coal of coal groove the scraper plate machine.
The scraper plate machine adopts frequency conversion drive, according to coal seam height in the scraper plate machine, regulates the speed of service of scraper plate machine; Adopt frequency conversion drive, the scraper plate machine is permanent torque drive, satisfies heavy load starting, reaches energy saving purposes.Also be that the scraper plate prow adopts frequency conversion drive.
The operating room module is arranged separately, adopts the isolated footing, and is relatively independent with the disintegrating machine platform, reduces vibration to the electric-control system influence, makes operating personnel have a working environment preferably.
According to moving the needs of establishing, this semi-fixed type Crushing Station is divided into to scraper plate machine module, disintegrating machine module, disintegrating machine support platform module, operating room module, phase transformation module five modules totally, moves through flat car and external force towing respectively and establishes.Scraper plate machine module is divided into scraper chain, middle cell body, chain-drive section again, and each one moves separately and establishes.
The present invention compared with prior art has the following advantages and good effect:
1, this semi-fixed type Crushing Station starts steadily, and effectively coal seam height in the limiting scraper machine prevents the down-stream system overload, and is reliable.
2, the scraper plate machine of this semi-fixed type Crushing Station adopts frequency conversion drive, regulates the scraper plate machine speed of service according to coal seam height in the scraper plate machine.
3, the material feeding section of the scraper plate machine of this semi-fixed type Crushing Station is same inclination angle with promoting the transportation section, and cancellation becomes the slope section, thereby reduces the operation power consumption service life of improving the scraper plate machine.
4, this semi-fixed type Crushing Station module sets up separately rationally, moves and establishes conveniently.
