Description
Technical field
The present invention relates to a kind of methods reducing elevator disorderly closedown number, belong to field of mechanical technique.
Background technology
In recent years, with the promotion of grinding process management level, the unit-hour output of 4# cement grinding mills has had reached 160t or more,
But during real-world operation it was found that with 4# line cement mill system unit-hour outputs promotion, the failure frequency of 0510 elevator
Hair has seriously affected the running rate of grinding machine.Mill feed material is pooled on belt conveyor, and roll squeezer is conveyed by elevator
Current stabilization storehouse, after roll squeezer rolls, material is delivered to V-type powder concentrator by 0510 elevator, and qualified material is by Geldart-D particle
To whirlwind harvest device, underproof material return current stabilization storehouse again passes by roll squeezer and mills；As shown in pink colour arrow, material is by gas
After power is delivered to rotoclone collector, collects the material to get off and milling mill is entered by skewed slot, go out grind materials then by grinding tail delivery system
System is directly put in storage.What 0510 elevator was selected is novel bucket type single-chain hoist will not only undertake from the point of view of its process layout
The conveying task of grinding machine normal volume will also include that elevator returning charge, V-type powder concentrator return additional defeated such as powder, roll squeezer material leakage
Task is sent, once cement grinding mill host and roll squeezer two systems can be caused while shut down simultaneously by shutting down, and it is long there are processing time,
Phenomena such as difficulty is big.0510 elevator belongs to central sprocket wheel elevator, and tail wheel not only has transmission, also acts as the work of tension chain
With once occurring because tail wheel slider stroke is excessive, and caused the foreign matters such as broken forging to snap into inside sliding block so that hoister rear wheel is by card
A position to lose the effect of tightening lifting machine chain, and then cause elevator current fluctuation big.Work as steady flow
When being less than 20t again, the fine granular materials returned from V-type powder concentrator can not mix with the large granular materials newly to put in storage
It is even just to fall into roll squeezer, it easily causes roll squeezer blanking and segregation phenomenon occurs, so as to cause the distracted degree of roll squeezer both sides roll surface
Inconsistent, roll gap deviation is big, is also easy to produce roll squeezer blanking fluctuation, is fluctuated so as to cause 0510 elevator blanking.Live practical survey
The gap values between rollers of amount are bigger than normal compared with middle control parameter, and thus consequence caused by meeting is in production process, and a standing wave occurs in practical roll gap
It needs that means is taken to adjust when dynamic in order to avoid being forced to move back roller, but cause operator to adjust since the reaction of middle control parameter is not accurate enough at this time
Not in time so that roll squeezer roll gap causes some materials just not fall directly into 0510 by roll-in without restoring normal in time
Elevator can cause 0510 elevator electric current higher since the part doses is uncontrollable, and fluctuate larger.
Invention content
The present invention provides a kind of method reducing elevator disorderly closedown number, can overcome defect described above.
In order to solve the above technical problems, the present invention provides the following technical solutions：A kind of reduction elevator disorderly closedown number
Method, install two limited blocks additional on two wood side-guides being connect with tail wheel, two limited blocks are in the medial surface of two wood side-guides,
It is opposite each other；The gap that roller end face and side shield are reduced using hydraulic jack is restored to move roller end face by full size；Or technological transformation
Side shield reduces the gap of side shield and roller end face；And one sensor is set in gap location, and in original operating system directly
Adjustment increases the visual limiter in scene.
Further, side shield and the gap in roller end face must not exceed 5mm.
Further, according to the gap shape and gap measured, respective shapes and thickness are welded on side shield
Wearing plate.
Further, respectively increase an adjustable limiter, the sliding block of limiter and dynamic roller in roll-in motorized rollers both sides
It is connected, the true roll gap of roller is moved in real time reaction, is adjusted in time at the scene when gap values between rollers are more than limit value.
This method for reducing elevator disorderly closedown number of the present invention, can reduce the disorderly closedown of elevator
Number, and be allowed within real-time controlled range.
Description of the drawings
Fig. 1 is prior art elevator bottom substance schematic diagram；
Fig. 2 is that the present invention promotes motor spindle standoff features schematic diagram.
Specific implementation mode
Fig. 1 is prior art elevator bottom substance schematic diagram；Fig. 2 is that the present invention promotes the signal of motor spindle standoff features
Figure.As depicted in figs. 1 and 2, the method for reducing elevator disorderly closedown number is as follows：On two wood side-guides 2 being connect with tail wheel 1
Install two limited blocks 3 additional, two limited blocks 3 are in the medial surface of two wood side-guides 2, opposite each other；It is reduced using hydraulic jack
The gap in roller end face and side shield is restored to move roller end face by full size；Or technological transformation side shield, reduce side shield and roller end face
Gap；And one sensor is set in gap location, and directly adjustment increases the visual limiter in scene in original operating system.
Side shield and the gap in roller end face must not exceed 5mm.
According to the gap shape and gap measured, the wearing plate of respective shapes and thickness is welded on side shield.
Respectively increase an adjustable limiter in roll-in motorized rollers both sides, the sliding block of limiter is connected with dynamic roller, in real time
The true roll gap of roller is moved in reaction, is adjusted in time at the scene when gap values between rollers are more than limit value.
In August, 2014 has been counted below to 0510 elevator disorderly closedown number November in 2014：
Table one：In August, 2014 is to 0510 elevator disorderly closedown number November in 2014
As can be seen from Table I after implementation, in August, 2,014 0510 elevator disorderly closedown number in -2014 years November
It is not above 5 times, realizes target.
This method for reducing elevator disorderly closedown number of the present invention, direct economic benefit：By various aspects
Calculate, every time because 0510 elevator stop jumping due to stop mill caused by economic loss be about 0.5 ten thousand yuan；Roll squeezer side shield technological transformation is primary
Spent material and cost of labor is about 0.1 ten thousand yuan, and will not increase additional stop using monthly 4 times time between predetermined repairs technological transformation
Machine expense；The expense that another increasing changes roll squeezer scene limiter is 1.3 ten thousand yuan, and maintenance cost is very low negligible；Thus finally
Going out monthly economic benefit is： 0.5*（13.5-4）Yuan/month of -0.1*4=4.35 ten thousand is that is in addition to first month increasing changes equipment
Outside spent expense, remaining every month 11.1 ten thousand yuan of escapable cost；Indirect economic effect：This time movable implementations of QC, no
Expected purpose is only reached, also so that the operating of cement mill system gets better protection；It is directed to 0510 elevator simultaneously
The technological transformation that disorderly closedown is done, can also extend the service life of 0510 elevator, reduce its maintenance cost etc. is production cost
It is more preferable management provide advantage.
Specific implementation mode of the present invention does not constitute the limitation to the application range, every in present inventive concept
Within spirit and principle, all any modification, equivalent and improvement etc. that one of skill in the art can make should be included in
Within protection scope of the present invention.
