Abstract
The utility model relates to a coal pulverizer especially relates to a colliery machinery's novel medium speed pulverizer. Novel medium speed pulverizer, including roller portion, down support body, well support body and establish the mill support on the speed reducer, the nozzle cascade in the mill support outside, the roller shell working face central point of roller portion is established on the pitch circle of mill tile, and the support arm of roller portion is fixed on the upper portion of well support body, and the middle part of well support body is equipped with the spring -loaded device, is equipped with the separator in well support body top, and the separator middle part is equipped with the coal breakage pipe. The utility model discloses an advantage effect: owing to has cancelled loading frame, when having saved some investments, has also made the grinding roller examine and repair and conveniently save time to production efficiency has been improved. The utility model discloses with advantage collection in an organic whole of MPS medium speed pulverizer and HP coal pulverizer, make the maintenance simple and convenient, down time is short. And on the mill during no coal, because of the roller shell working face with grind not direct contact of tile to can unloadedly start, when having reduced start -up force moment, also reduced the power consumption of system, reached energy -conserving purpose.
Description
Technical field
This utility model is related to a kind of coal pulverizer, more particularly to a kind of new medium-speed pulverizer in coal mine machinery field.
Background technology
At present, the grinding forces major part in MPS medium-speed pulverizer central roll sub-portions is produced by hydraulic cylinder or spring loads,
Uniformly it is distributed on grinding roller by loading frame, because loading frame structure is big, during maintenance roller, needs to unload loading frame
After dismounting, rolling mechanism is put on mill roller could to be routed up and overhaul outside cylinder, the regular dismounting, replacing for roller,
The maintenance of equipment, wastes time and energy, and greatly reduces the service efficiency of equipment.
The content of the invention
A kind of new medium-speed pulverizer is provided in order to solve above-mentioned technology this utility model, it is therefore an objective to convenient to overhaul, improved
Production efficiency.
It is realized in up to above-mentioned purpose this utility model：New medium-speed pulverizer, including roller sections, lower frame,
Middle support body and the mill bearing being located on reductor, the nozzle ring of mill support outer, the roller set center of working face point of roller sections
It is located on the pitch circle of millstone sheet, the support arm of roller sections is fixed on the top of middle support body, in the middle part of middle support body, is provided with spring loads dress
Put, separator is provided with above middle support body, coal spout is provided with the middle part of separator.
Described is provided with inert gas piping on separator.
Sealing air pipe is provided with described lower frame.
Described lower frame is bolted on the basis of.
Described mill bearing is put together on reductor；The side of nozzle ring is fixed on abrasive disk seat, nozzle ring it is another
It is sealing structure between side and housing.
Lower frame sealing ring is provided between described mill bearing and lower frame.
The support arm of described roller sections is provided with wear-resistant block, wear-resistant block and spring charging device back contacts.
Gap is provided between described roller set work surface and millstone sheet.
Described support arm is fixed with middle support body by connecting bolt.
The utility model has the advantages of：Due to eliminating loading frame, while saving part investment, also examine grinding roller
Repair it is convenient and time-saving, so as to improve production efficiency.The advantage of MPS medium-speed pulverizers and HP coal pulverizers is combined in one by this utility model
Body, makes maintenance easy, and downtime is short.And on mill without coal when, because roller set work surface and mill watt are not directly contacted with, so as to can
The power consumption of system with starting under no load, while reducing staring torque, is also reduced, the purpose of energy-conservation has been reached.
