Abstract
A roller disc type medium speed coal milling machine relates to the technical field of coal milling machines and is composed of a motor, a speed reducer, a milling disc, a milling roller, a pressurization device, a casing, a separator, a coal dropping pipe, an outlet pipe, a hot air inlet pipe, a hot air annular chamber and a basic block. The coal milling machine is characterized by further comprising a roller turning out device, and the basic block is made of rigid materials. The basic block of the medium speed coal milling machine is light in weight, rigid base replaces elastic base, and capital construction investment is reduced. The roller turning out device enables overhauling working amount to be greatly reduced, and the coal milling machine is small in overhauling strength and short in overhauling time.
Description
Technical field:
The utility model relates to the coal pulverizer technical field, is specifically related to a kind of disc roll pulverizer.
Background technology:
MPS type medium-speed pulverizer is a kind of disc roll pulverizer that is manufactured and designed by German Babcock company.MPS type vertical roll grinder is original to be the advanced type that building stones grind that is used for of German Pfeiffer company development, by German Babcock company patent of introduction technology, MPS type vertical roll grinder is applied to the coal dust preparation system of coal-fired station.This coal-grinding type is since 1958 come out, and by the technology gradual perfection of the said firm, specification series constantly increases, and has formed the more complete series of 27 kinds of specifications at present, has become the desirable powder manufacturing apparatuses of industry such as power station, metallurgy, chemical industry, cement building material at present.The MPS type coal pulverizer that is now moving in the world is near 4000, and operation result shows that this type is better than the coal pulverizer of other form.But all be to use elastomeric material to make on the basis of existing disc roll pulverizer, basic blocks weight is large, and capital expenditure is large, and existing disc roll pulverizer is very inconvenient in the maintenance of day norm roller, and the repair time is long, and labour intensity is large.
The utility model content:
It is a kind of lightweight that technical problem to be solved in the utility model is to provide, and capital expenditure is few, the disc roll pulverizer of easy access and maintenance.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
Disc roll pulverizer, formed by motor, reductor, mill, grinding roller, pressue device, shell, separator, coal spout, outlet, hot blast inlet tube, annular hot-blast chamber and basic blocks, it is characterized in that: described medium-speed pulverizer comprises that also the mould roller routs up device, and described basic blocks is rigid material.
Be mounted with the warm-air pipe that draw hot blast inlet tube and annular hot-blast chamber between the top of described mill and each grinding roller, the top of described warm-air pipe is provided with to blow raises device.
The bottom of described separator and coal spout is equiped with back the again separator that powder is sent out plate, triangle spiral board, zigzag annular plate, annular plate composition.
Top annulus between shell and separator is equiped with the axial adjustment baffle plate.
The beneficial effects of the utility model are: the utility model basic blocks is lightweight, and capital expenditure has been reduced on rigid foundation elasticity of substitution basis, and the mould roller is routed up device, and the use and maintenance workload reduces greatly, and maintenance intensity is little, and the repair time is short.
Description of drawings:
Fig. 1 is the utility model master TV structure schematic diagram.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, disc roll pulverizer, formed by motor 1, reductor 2, mill 3, grinding roller 4, pressue device 5, shell 6, separator 7, coal spout 8, outlet 9, hot blast inlet tube 10, annular hot-blast chamber 11 and basic blocks 12, medium-speed pulverizer comprises that also the mould roller routs up device 13, and basic blocks 12 is rigid material.Be mounted with the warm-air pipe 14 that draw hot blast inlet tube 13 and annular hot-blast chamber between the top of mill 3 and each grinding roller 4, the top of warm-air pipe 13 is provided with to blow raises device 15.The bottom of separator 7 and coal spout 8 is equiped with back the again separator that powder is sent out plate 16, triangle spiral board 17, zigzag annular plate 18, annular plate 19 compositions.Top annulus between shell 6 and the separator 7 is equiped with axial adjustment baffle plate 20.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
