Description
Technical field
The present invention relates to a kind of grinding roller of coal pulverizer, more particularly to a kind of detachable ceramic-metal composite base medium-speed pulverizer
Coal machine grinding roller.
Background technology
Medium-speed pulverizer refers to the coal pulverizer that working speed is 50~300r/min, and motor passes through reductor band movable grinding disc
Rotate, material falls in mill center through lock feeding device from charging aperture, while hot blast enters in mill from air inlet.With mill
Rotate, material under the influence of centrifugal force, moves to mill edge, by being rolled during annular groove on mill by grinding roller
Crush, the material after crushing is taken up at mill edge by vane high velocity air, and bulky grain falls directly on and crushed again on mill, gas
When material in stream passes through upper part sedimentator, in the presence of rotor, coarse powder falls on mill grinding again from cone bucket, closes
Lattice fine powder goes out mill with air-flow, is collected by dust arrester installation, as product.
From above-mentioned medium-speed pulverizer operation principle, it is seen that, the broken critical component of material (coal dust) is mill and mill
Roller, and both parts requirement has sufficiently high wearability to ensure the normal use of coal pulverizer, the work on Roller of Coal Grinder surface
It is the process constantly hit and milled as process, roller surface is highly prone to wear.
Currently, medium-speed coal mill roller is typically all integrally cast using high rigidity, high-wearing feature alloy (such as rich chromium cast iron)
Cause type.Problems with use be present in such grinding roller：(1) maintenance difficult；, must when Roller of Coal Grinder is due to wear out failure
Must be by grinding roller integral replacing, by taking HP-1003 type medium-speed pulverizers as an example, grinding roller diameter reaches 1451mm, weighs 1.71 tons, changes difficulty
Very big, labor strength is high；(2) because grinding roller integral replacing maintenance difficulty is big, each Maintenance Demand Time is longer, and (maintenance is more
Coal pulverizer needs to shut down when changing grinding roller, it is impossible to produces), influence to produce；(3) whole mill is changed due to roller surface wear out failure
Roller, cost of equipment maintenance are high.
The conventional design means for solving above-mentioned technical problem are to prepare medium-speed coal mill roller roller using more resistant material
Set, but it simply improves the wearability of grinding roller, extends the maintenance cycle of coal pulverizer, but do not solve grinding roller fundamentally
The problems such as integral replacing cost is high, maintenance labor intensity is big, the maintenance needs time is long.
The content of the invention
To solve above technical problem, the present invention provides a kind of detachable ceramic-metal composite base medium-speed pulverizer mill
Roller, more roll change set is only needed after Roller of Coal Grinder abrasion, maintenance cost is reduced, improves maintenance efficiency.
To achieve the above object, the invention provides following technical scheme：
The present invention provides a kind of detachable ceramic-metal composite base medium-speed coal mill roller, and the grinding roller includes grinding roller sheet
Body and roller set, the roller set are made up of the multiple composite blocks being detachably connected with the grinding roller body.
Optionally, the material of the composite block is Ceramic Reinforced MMCs.
Optionally, the side of the grinding roller body is provided with the notch for clamping the roller set.
Optionally, the notch and the grinding roller body are integral type structure.
Optionally, the notch and the grinding roller body are fabricated structure, and the notch is by fastening spiral shell
Bolt is fixed on the grinding roller body.
Optionally, the notch includes major part neck and microcephaly's neck, and the major part neck is arranged at the grinding roller
The bottom of this body side surface, microcephaly's neck are arranged at the top of described this body side surface of grinding roller, the both ends difference of the composite block
It is stuck in the major part neck and microcephaly's neck.
Optionally, the model HP-1003 of the coal pulverizer.
Optionally, the quantity of the composite block is 24 pieces, and the composite bed thickness of the composite block is 41mm.
Optionally, the major part neck size is 15mm × 35mm, and microcephaly's neck size is 20mm × 35mm.
Optionally, the material of the grinding roller body is Cr5。
The present invention achieves following technique effect relative to prior art：
(1) can effectively solve the problems, such as existing medium-speed pulverizer maintenance difficult, reduce maintenance difficulty and the work of equipment
Intensity, maintenance efficiency are lifted；
(2) after existing medium-speed coal mill roller wear out failure can only integral replacing, the present invention in medium-speed pulverizer only need
More roll change set, beneficial to the maintenance in later stage, repair density and maintenance time are reduced, substantially reduces maintenance cost, is solved
Existing Roller of Coal Grinder changes the problems such as difficult, labor intensity is big, maintenance cost is high.
By taking HP-1003 medium-speed pulverizers as an example, monoblock type medium-speed coal mill roller weight is 1.71 tons, detachable grinding roller
1.16 tons of this body weight, detachable roller set weight is 528 kilograms.Originally can only be integral replacing, patented product of the present invention only needs
Will more roll change set part.
(3) because the present invention is by the way of body and roller cover two parts combination grinding roller, bulk material is by original Cr20Become
For Cr5, cost is greatly reduced.
By taking HP-1003 medium-speed pulverizers as an example：Cr20Manufacturing cost about 70,000/ton, the manufacture of the grinding roller of a coal pulverizer
Ten thousand yuan of cost about 1.71 × 7=11.97, is prepared using patented method of the present invention, and its manufacturing cost is about：1.16×1.8+
0.528 × 7=5.784, ten thousand yuan of (Cr5Be currently manufactured as this about 1.8 ten thousand/ton).That is, the cost of one mill grinding roller just reduces
11.97-5.784=6.186 ten thousand yuan.
