Abstract
The utility model relates to an immediately, grind separator rooting -in of blades structure, including rotary drum, separator blade, the separator blade includes the blade body, the blade body includes rotary drum connecting portion and blade homework department, be equipped with the fixed orifices on the rotary drum connecting portion, the fixed orifices corresponds with the connecting hole of installing the connecting plate on the rotary drum to through fastening bolt and rotary drum fastening connection, blade homework department is equipped with four taut holes along the blade length direction, in the taut downthehole lacing wire that is equipped with respectively, four downthehole lacing wires of take -up become crisscross and set up, and the adjacent blade of the both ends of lacing wire connection, join in marriage at the both ends of lacing wire and are equipped with lock nut. Adopting above -mentioned technical scheme, setting up the lacing wire promptly between the well upper portion of present separator blade, stopped the separator and fallen the blade trouble, improved the separator running efficiency, the mill running efficiency obtains improving on year -on -year basis, and the mill system operates steadily immediately, and the power consumption reduces, has guaranteed the life of separator blade simultaneously, and maintenance volume and recondition expense reduce.
Description
Technical field
This utility model belongs to manufacture of cement coal dust and makes technical field, particularly relates to a kind of coal Vertical Mill separator blade
The improvement of fixed form.
Background technology
Company's 2# coal mill system is Hefei Cement Research Design Institute HRM1700M vertical mill system, within 2004, goes into operation and runs,
Due to design reasons, there is frequent obscission, affect system properly functioning, although take in Vertical Mill separator blade
Measure, such as: change higher level intensity and fix bolt, bolt position increases wear-resistance protective sleeve etc., but basic solution is not asked
By analysis and summary, topic, finds that the main cause causing blade frequently to drop is that vane stress face is big and fixing point is few, blade
Frequent swing, the fracture of fastening bolt fatigue damage causes, and makes to affect every factor of separator stable operation by technological transformation
Have been resolved.
Summary of the invention
This utility model provide for solving technical problem present in known technology a kind of simple in construction, easy to install,
Stop separator leaf abscission situation, improve the Vertical Mill separator blade installation structure of vertical mill system mill efficiency.
This utility model is adopted the technical scheme that by solving technical problem present in known technology:
A kind of Vertical Mill separator blade installation structure, including rotary drum, the separator blade being fixedly mounted on rotary drum, it is special
Levy and be: described separator blade includes that blade body, described blade body include rotary drum connecting portion and blade homework department,
Described rotary drum connecting portion is provided with fixing hole, and described fixing hole is corresponding with the connecting hole of the connecting plate being arranged on rotary drum, and
Being fastenedly connected with rotary drum by fastening bolt, described blade homework department is provided with four tension holes along length of blade direction；Drawing
Being respectively equipped with lacing wire in tieholen, the lacing wire in four tension holes becomes to be crisscross arranged, and the two ends of lacing wire connect adjacent blade,
It is fitted with locking nut at the both ends of lacing wire.
This utility model can also use following technical measures:
Described four tension holes are located along the same line.
This utility model has the advantage that with good effect: owing to this utility model uses technique scheme, i.e. existing
Set up lacing wire between the middle and upper part of some separator blades, stopped separator and fallen blade fault, improve separator operating
Efficiency, mill running efficiency is improved on year-on-year basis, and vertical mill system operates steadily, and power consumption reduces, and ensure that separator simultaneously
The service life of blade, maintenance amount and the cost of overhaul reduce.

Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate
Accompanying drawing describes in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of Vertical Mill separator blade installation structure, including rotary drum 1, be fixedly mounted on rotary drum
Separator blade 2, described separator blade includes that blade body 2-1, described blade body include rotary drum connecting portion 2-10
It is provided with fixing hole 2-11, described fixing hole 2-11 and installation with blade homework department 2-20, described rotary drum connecting portion 2-10
On connecting plate 1-1 on rotary drum 1, connecting hole is corresponding, and is fastenedly connected with rotary drum by fastening bolt 3, described blade
Homework department 220 is provided with four tension hole 2-21 along length of blade direction；Being respectively equipped with lacing wire 4 in tension hole, four are drawn
Lacing wire in tieholen becomes to be crisscross arranged, and the two ends of lacing wire 4 connect adjacent blade, are fitted with lock at the both ends of lacing wire
Jack panel 5.In order to ensure the stability that separator blade runs when Vertical Mill operates, described four tension holes are positioned at always
On line.
Use technique scheme, i.e. between the middle and upper part of existing separator blade, set up lacing wire, stopped separator
Falling blade fault, improve separator running efficiency, mill running efficiency is improved on year-on-year basis, and vertical mill system operates steadily,
Power consumption reduces, and ensure that the service life of separator blade, maintenance amount and the cost of overhaul reduce simultaneously.
The above is only to preferred embodiment of the present utility model, not makees this utility model any pro forma
Limit, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations with
Modify, belong in the range of technical solutions of the utility model.
