Abstract
The utility model discloses a rotating ring structure of a coal pulverizer, which comprises a pulverizing ring tray and nozzle blades distributed in the circumferential direction of the pulverizing ring tray, wherein the nozzle blades are fixedly mounted on the pulverizing ring tray through connecting pieces. The rotating ring structure has better ventilation effect and is low in integral cost.
Description
Technical field
The utility model relates to a kind of coal pulverizer rotating ring, specifically relates to the motor-driven ring structure of a kind of roll-type coal-grinding.
Background technology
The application is the motor-driven ring structure of a kind of roll-type coal-grinding.The function of this rotating ring structure is: under the drive of roll-type coal pulverizer drive plate, rotating ring mechanism rotates simultaneously with mill, and wind is from evenly entering by nozzle ring around the bull ring, and the coal dust intermixture oven dry that will tangentially throw away from the bull ring also is delivered to separator.
Original roll-type coal pulverizer as the ZGM coal pulverizer, is that nozzle vane and bull ring pallet ring on the rotating ring is cast in block with reference to Figure of description 1 and 2 its rotating ring structures, follows the mill rotation, and one time wind passes through from nozzle ring.But bull ring pallet outer lower portion has a tapering, and when mill drove the nozzle vane rotation, influence was ventilated.
On the other hand, casting integrated structures shape itself if a certain funtion part lost efficacy, must cause the inefficacy of whole parts, caused a large amount of spare parts consumptions, whole cost is than higher.
Summary of the invention
Therefore, the utility model provide a kind of coal pulverizer rotating ring structure that preferable ventilation effect is arranged, and whole cost is low at the ventilate defective of of poor quality and whole Cheng Mugao of present coal pulverizer rotating ring structure.
The technical solution adopted in the utility model is:
The utility model coal pulverizer rotating ring structure comprises bull ring pallet and the nozzle vane that circumferentially distributes along this bull ring pallet, and described nozzle vane installs on the described bull ring pallet by connector.
Provide a kind of rotating ring of new structure form according to the coal pulverizer rotating ring structure of technical solutions of the utility model, in use be convenient to change the nozzle vane spare part of rapid wear, save unnecessary spare parts consumption, just the consumption of bull ring pallet.
On the other hand, this programme is easy to eliminate the tapering of pallet outer lower portion than prior art, is convenient to a wind and passes through when grinding machine is produced, and reduces the dust pollution that causes because of malleation.
Above-mentioned coal pulverizer rotating ring structure, the side array of described bull ring pallet are useful on the groove of the described nozzle vane in location.
Above-mentioned coal pulverizer rotating ring structure also comprises a blade cover that is assembled together with described bull ring pallet one end face, and all nozzle vanes all are affixed to described blade and put according to form is installed to fixed blade.
Above-mentioned coal pulverizer rotating ring structure, described blade cover is connected to being connected by axial bolt with described bull ring pallet.
Above-mentioned coal pulverizer rotating ring structure, described nozzle vane and described blade cover are the integrative-structure of casting.
Above-mentioned coal pulverizer rotating ring structure, described blade cover is one, an end of nozzle vane is connected to this blade and puts.
Above-mentioned coal pulverizer rotating ring structure, described blade cover is positioned at the nozzle-end side.

Fig. 3 is the main TV structure schematic diagram according to a kind of coal pulverizer rotating ring structure of wooden utility model technical scheme.
Fig. 4 is the B-B sectional structure schematic diagram of Fig. 3.
Among the figure: 1, nozzle vane, 2, the bull ring pallet, 3, tapered configuration, 4, bolt, 5, nozzle-end, 6, the blade cover, 7, bolt hole, 8, bolt hole.
The specific embodiment
With reference to explanation accompanying drawing 3 and 4, it shows a kind of coal pulverizer rotating ring structure, the basic scheme of this rotating ring structure is that it comprises bull ring pallet 2 and the nozzle vane 1 that circumferentially distributes along this bull ring pallet, and described nozzle vane installs on the described bull ring pallet by connector.
The design of this basic scheme is an independently spare part of consumable accessory nozzle vane conduct, and the physical life of bull ring pallet is long, and for the replacing of rotating ring structure, it is just passable often only to need to change nozzle vane; This basic structure need not to consider the setting of tapered configuration simultaneously.
Based on above-mentioned basic scheme, those skilled in the art can select or make up following technological means according to the needs of oneself:
Considering under the easy-to-dismount situation, in order to improve the bonding strength of nozzle vane, preferable means are grooves that the side array of described bull ring pallet is useful on the described nozzle vane in location, structure about groove has two kinds of basic selections, a kind of basic selection is a circumferential equilibrium of forces and in the location that makes progress in week, another kind of situation is except considering first kind of situation, also needs to consider spacing on the centrifugal direction.Therefore, the groove of selecting according to this can be rectangular channel, T type groove or dovetail groove.
Further, a blade cover 6 that is assembled together with described bull ring pallet one end face can also be set, all nozzle vanes all are affixed to described blade and put according to form is installed to fixed blade, the location of aspect nozzle vane not only, and easy to assembly, efficient height, bulk strength are also high.
Preferably, consider the needs of assembling aspect, described blade cover is connected to being connected by axial bolt 4 with described bull ring pallet.
Further, described nozzle vane and described blade cover be convenient to large-scale production, and interchangeability are good for the integrative-structure of casting.
Preferably, described blade cover is one, and an end of nozzle vane is connected to this blade and puts, and is simple in structure, and satisfies the specification requirement of installing.
Preferably, described blade cover is positioned at nozzle-end 5 sides, the setting of having stopped tapered configuration.
