Description
Technical Field
The utility model relates to a granulator, especially an from power scraper disk granulator.
Background
The existing scraper of the disc type ball forming mill is mainly divided into three types: fixed scraper, unpowered scraper, electronic gyration scraper.
Although the fixed scraper is simple, the defects are that the resistance is large, the tray bottom cleaning effect is poor, the balling effect is influenced, the power consumption of a main motor is large, and the fixed scraper is basically eliminated;
the unpowered rotary scraper does not need to be additionally provided with a motor, and rotates by utilizing the speed difference and the moment difference of the contact between the scraper and the disc surface, but the resistance moment of the unpowered scraper is larger than the power moment, so that the unpowered scraper rotates sometimes and does not rotate sometimes, the disc bottom cannot be cleaned timely and effectively, and the balling quality is influenced;
the electric rotary scraping force can ensure the rotation of the scraper, but the motor and the speed reducer are additionally arranged at required positions and are vertically arranged, so that oil leakage is easy, the motor and the speed reducer are easy to damage under a dust working environment, the power consumption is increased, and the operation rate of equipment is influenced.
In addition, the power transmission system of the disc type pelletizer has a complex main transmission structure. The main shaft, the bearing, the big and small gears and the hub are connected with the disc surface to rotate, the main shaft is supported by a cantilever, and occupies a large space, so that the disc surface has the disadvantages of large swing, large vibration, high power consumption, many easily damaged parts and inconvenient maintenance.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical problem, the utility model provides an from power scraper disk granulator. The technical scheme is as follows.
The utility model provides an from power scraper disk granulator, includes balling-up disk, speed reducer, motor and transmission, transmission transmits motor power for the balling-up disk, makes it rotate, install the scraper in the balling-up disk, the scraper passes through the belt pulley and is connected with balling-up disk center, drives the scraper by the balling-up disk and rotates, the belt pulley rotates and installs on granulator support.
Furthermore, a coupler is arranged at the center of the barrel, the coupler is externally connected with a universal shaft and a main belt pulley group, and then the main belt pulley group is connected with a plurality of scrapers from the belt pulley group.
Furthermore, the transmission structure is that the motor sequentially transmits power to the speed reducer, the pinion and the bull gear to drive the balling disc to rotate, the bull gear is positioned on the outer ring of the slewing bearing, the inner ring of the slewing bearing is connected to a frame of equipment through the fixed supporting seat, the outer ring of the slewing bearing is fixed with the balling disc, and the outer ring of the slewing bearing rotates between the inner ring of the slewing bearing and the pinion.
Furthermore, a ball is arranged between the inner ring of the slewing bearing and the outer ring of the slewing bearing.
The scraper has the beneficial effects that the belt pulley of the rotary scraper is driven by the central belt pulley, so that the rotary scraper can effectively rotate. The rotating speed of the balling disc and the rotating speed of the rotary scraper are asynchronous by utilizing the slip ratio of the belt, so that the effect of clearing materials on the disc surface is ensured. The scraper overcomes the defects of the prior scraper, has the balling effect of a power scraper, has the advantages of simple unpowered scraper, difficult damage, low energy consumption and reliable operation.

Detailed Description
The technical solution of the present invention is further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the granulator comprises a balling disc 1, a speed reducer 4, a motor 3 and a transmission device 2, wherein the transmission device 2 transmits the power of the motor 3 to the balling disc 1 to enable the balling disc 1 to rotate, a scraper is arranged in the balling disc 1, the scraper 13 is connected with the center of the balling disc 1 through a belt pulley, the balling disc drives the scraper to rotate, and the belt pulley is rotatably arranged on a granulator support through a belt pulley bearing 16.
The preferable transmission structure is that the motor 3 sequentially transmits power to the speed reducer 4, the pinion gear 5 and the gearwheel 10 to drive the balling disc 1 to rotate, the gearwheel 10 is positioned on the slewing bearing outer ring 8, the slewing bearing inner ring 11 is connected to a rack of equipment through the fixed bearing seat 9, the slewing bearing outer ring 8 is fixed with the balling disc 1 through the flange 7, and the slewing bearing outer ring 8 rotates between the slewing bearing inner ring 11 and the pinion gear 5. And balls 12 are arranged between the inner slewing bearing ring 11 and the outer slewing bearing ring 8.
As shown in fig. 2, a scraper 13 is installed in the balling disk. The scraper 13 is connected with the center of the balling disk 1 through a planetary belt pulley, and the balling disk 1 drives the scraper 13 to rotate. Specifically, a coupling 18 is arranged at the center of the cylinder, the coupling 18 is externally connected with a universal shaft 17, is externally connected with main belt pulley sets 15 and 16, and is connected with a plurality of scrapers 13 through auxiliary belt pulley sets 14 and 16. The cardan shaft 17 solves the non-concentricity existing in the manufacturing, mounting and using processes, and the belt pulley of the rotary scraper is driven through the central belt pulley, so that the rotary scraper is guaranteed to rotate effectively. The rotating speed of the balling disc and the rotating speed of the rotary scraper are asynchronous by utilizing the slip ratio of the belt, so that the effect of clearing materials on the disc surface is ensured. The scraper overcomes the defects of the prior scraper, has the balling effect of a power scraper, has the advantages of simplicity, difficult damage, low energy consumption and reliable operation of the unpowered scraper.
