The fixed jacket that two semicircular double-deck barrel combinations constitute is interference fit with the grinding ring, and rubbing crusher normal during operation, the grinding ring is difficult to not hard up under the emery wheel strikes, and is resistant to vibration, can effectively improve the life of grinding ring. Meanwhile, the mounting, dismounting and replacement of the grinding ring are simpler and more convenient, the working efficiency is effectively improved, and the maintenance time is shortened; is easy to be popularized and applied.
Description
Technical field
The utility model relates to a kind of fixedly chuck of ultrafine crusher bull ring, belongs to size reduction machinery member field.
Background technology
Ultrafine crusher is to be widely used in the nonmetallic mineral deep processing, as the ultra-fine grinding equipment in each field such as mineral such as calcium carbonate, coarse whiting, kaolin, wollastonite and chemical industry, building materials, cement.The fixed structure of existing ultrafine crusher bull ring adopts barrel-type more, being about to bull ring is inserted in the cylindrical shell, loosening in order to prevent bull ring, this bull ring is pushed down with pressing plate on bull ring top, the shortcoming of this structure is that cylindrical shell and bull ring are difficult for holding tightly, after the equipment long-term operation, particularly in crushing process, because of being subjected to emery wheel to impact the high vibration that the roll extrusion comminuting matter causes bull ring, pressing plate is shaken cause becoming flexible, cause the loosening or rotation of bull ring thus, even the rhegma of shaking is bad, increase maintenance cost, reduced service life of equipment, influenced ordinary production.
The utility model content
In order to overcome the defective that exists in the above-mentioned prior art, the purpose of this utility model is to provide a kind of installation and maintenance convenient, the fixedly chuck of the ultrafine crusher bull ring of long service life.
To achieve these goals, the utility model adopts following technical scheme: a kind of fixedly chuck of ultrafine crusher bull ring, and it comprises the cylindrical shell that is sheathed on the bull ring outside, its characteristics are: described cylindrical shell is combined by two semicircle cylindrical shells; Described semicircle cylindrical shell is a semicircle double-layer barrel that is made of inner core and urceolus, is connected with some ribs between its inner core and the urceolus; Two interconnective radial side of semicircle double-layer barrel respectively correspondence be provided with adpting flange; Have at least 1 bolt connecting hole on the described adpting flange, by bolt two described semicircle double-layer barrels being fixed as one constitutes described fixedly chuck.
The inner core of above-mentioned semicircle double-layer barrel, urceolus, some ribs and adpting flange are the integrally casting moulding.
Have 1-10 bolt connecting hole on the above-mentioned adpting flange.
Adopt the technical solution of the utility model, its beneficial effect is as follows: 1, bull ring of the present utility model fixedly chuck connect and compose with bolting by two semicircular double-layer barrels; Wherein, semicircle double-layer barrel is connected with the inner barrel of some ribs with outer cylinder body and two the interconnective radial side of semicircle double-layer barrel adpting flange integrally casting moulding of corresponding setting respectively by the centre; The semicircle double-layer barrel of two integrally casting moulding becomes a complete cylinder chuck by adpting flange with Bolt Connection, the bull ring of ultrafine crusher is clipped between two semicircle double-layer barrels that are fixed as one, fixedly chuck and bull ring that two semicircle double-layer barrels constitute are interference fit, bull ring is fixedly clamped at this fixedly in the chuck, during the pulverizer operate as normal, bull ring is not easy to become flexible under emery wheel impacts, and vibration resistance.Overcome traditional pulverizer bull ring and be inserted in the whole cylindrical shell, cylindrical shell and bull ring are difficult for holding tightly, and the high vibration when pulverizer is worked causes the bull ring bad defective of rhegma of shaking, the service life of effectively having improved bull ring.2, two fixedly designs of chuck of semicircle double-layer barrel, the handling procedure of bull ring is simplified, when needs are changed the bull ring accessory, only need unclamp the fixedly flange bolt on chuck 1 both sides, make two semicircle double-layer barrels separately, the bull ring that damages is taken off, change new bull ring, effectively shorten maintenance time, maintained easily maintenance, improved operating efficiency.Be of value to and apply.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the fixedly chuck 1 of ultrafine crusher bull ring of the present utility model is that two semicircle cylindrical shell butt joints fixedly form.Semicircle cylindrical shell be double-deck the setting, comprises inner barrel 13 and outer cylinder body 12, the vertical ribs 15 that are connected with some support inner barrels and outer cylinder body between inner barrel 13 and the outer cylinder body 12; Two mutual joints of semicircle double-layer barrel are respectively equipped with adpting flange 11, offer 1 bolt connecting hole on this adpting flange 11 at least; Fixedly chuck 1 upper end that is connected as one by bolting connects with the hierarchy system of ultrafine crusher by upper flange 14; Fixedly chuck 1 lower end is affixed with the support of ultrafine crusher by lower flange 14 '; Semicircle cylindrical shell is by inner barrel 13, outer cylinder body 12, rib 15 and adpting flange 11 integrally casting moulding.
Adpting flange 11 on two semicircle double-layer barrels docks mutually, and by bolt two semicircle double-layer barrels being fixed as one constitutes fixedly chuck 1 of the present utility model.
Bolt connecting hole on the adpting flange 11 can be offered 1-10, and the quantity that bolt connecting hole is offered will be determined according to the size of pulverizer type usually.Present embodiment offers 3 bolt connecting holes.
The utility model fixedly two semicircle double-layer barrels of chuck 1 is respectively whole iron casting, material selection spheroidal graphite cast-iron or grey cast-iron TH200.
Installation of the present utility model and use-case are as follows:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, during installation, earlier with combined integrated double shell fixedly the bolt of the adpting flange 11 of chuck 1 both sides unclamp, make two and half cylindrical shells open the gap, bull ring 2 is packed in the inner barrel 13 of fixedly two butt joints of chuck 1, lock the adpting flange 11 of cylindrical shell chuck both sides then, bull ring 2 firmly is clamped in fixedly in the chuck 1; At this moment, the chuck that forms between inner barrel 13 and the outer cylinder body 12 has constituted the passage of material and air-flow.In the material grinding process; bull ring 2 is pulverized material by the impact roll extrusion of a plurality of emery wheels 3; the vibration of bull ring 2 is very big in the crushing process; but because inner barrel 13 is an interference fit with bull ring 2; bull ring 2 is tightly embraced the jail by inner barrel 13, is difficult for loosening or rotation, so bull ring 2 is not easy to become flexible under emery wheel impacts; protect bull ring 2 rhegma that is difficult for shaking bad, effectively prolonged the service life of this disintegrating apparatus.When needs are changed the accessory of bull ring 2, only need unclamp the bolt on the adpting flange 11 on fixing chuck 1 both sides, two semicircle double-layer barrels are separated, bull ring 2 just can take off easily, in time changes; Also be convenient to simultaneously maintenance, shorten maintenance time.
