Description
Technical field
The utility model is related to a kind of blast furnace coal powder preparation system, which can automatically send out when vibrating screen breaks down
Warning message belongs to milling or crushing technology field.
Background technology
When blast furnace coal powder preparation system is run, raw coal becomes coal dust through grinding and drying, and is then deposited in powder collecting system
In cloth bag ash bucket, then along lower hopper bottom coal unloading tube road fall, enter in pulverized coal bin through lower coal valve group and reciprocating sieve, finally from
Pulverized coal bin is dispensed into each injection tank.It is found in production process, reciprocating sieve is the higher portion of failure rate in blast furnace coal powder preparation system
Part, once vibrating screen breaks down, the coal unloading tube road of upper part will be blocked by coal dust, make coal dust that can not be transported to pulverized coal bin,
To influence being smoothed out for production.Since existing blast furnace coal powder preparation system is all without fault detection capability, vibration is sifted out
Generally it is difficult to find in time after existing failure, causes system to operate with failure time lengthening, greatly reduce blast-furnace coal powder and prepare system
The working efficiency of system.
Utility model content
The purpose of this utility model is that for the drawback of the prior art, provide a kind of with the sieve fault detection capability that shakes
Blast furnace coal powder preparation system is operated with failure the time with shortening system, improves the working efficiency of coal dust preparation system.
Problem described in the utility model is realized with following technical proposals：
A kind of blast furnace coal powder preparation system with the sieve fault detection capability that shakes, composition include coal pulverizer, cloth bag case, row
Wind turbine, cloth bag ash bucket and pulverized coal bin, the air inlet of the cloth bag case are connected by the coal outlet of pipeline and coal pulverizer, air outlet with
Exhaust blower connects, and the discharge in cloth bag bottom portion connects cloth bag ash bucket, and the pulverized coal bin is located at below cloth bag ash bucket, cloth bag ash bucket
The coal unloading tube of bottom is connected through lower coal valve group and vibrating screen and the coal feed point of pulverized coal bin successively, the side wall in cloth bag ash bucket and vibration
It sieves and is equipped with temperature sensor on the coal unloading tube of coal-feeding end, the signal output end of each temperature sensor is prepared with blast-furnace coal powder is
The DCS connections of system.
The above-mentioned blast furnace coal powder preparation system with the sieve fault detection capability that shakes, the air intake and outlet air end of the cloth bag case
Pipeline on the temperature sensor being connected with the DCS of blast furnace coal powder preparation system is also installed.
The above-mentioned blast furnace coal powder preparation system with the sieve fault detection capability that shakes, the lower part of the cloth bag case are equipped with multiple cloth
Bag ash bucket, each cloth bag ash bucket are connected by coal unloading tube and lower coal valve group with multiple vibrating screens.
The utility model supervises the temperature of cloth bag ash bucket and vibrating screen top coal unloading tube using temperature sensor in real time
It surveys, and judges that vibrating screen whether there is failure according to the situation of change of the two, thus can find and exclude in time vibrating screen
Failure prevents coal unloading tube from blocking for a long time, improves the working efficiency of coal dust preparation system.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model.
In figure respectively marked as：1, coal pulverizer, 2, cloth bag case, 3, cloth bag ash bucket, 4, pulverized coal bin, 5, vibrating screen, 6, lower coal valve
Group, 7, exhaust blower, the temperature sensor of T1~T8, the first temperature sensor~the 8th.
Specific implementation mode
The utility model provides a kind of improved blast furnace coal powder preparation system, which can find vibrating screen event in time
Barrier ensures that production is smoothed out.
Referring to Fig. 1, the utility model includes coal pulverizer 1, cloth bag case 2, cloth bag ash bucket 3, pulverized coal bin 4, vibrating screen 5, lower coal
Valve group 6, exhaust blower 7 and multiple temperature sensors.
Coal dust is made by grinding and drying in coal pulverizer 1 in raw coal, cloth bag case 2 is extracted by exhaust blower 7, in cloth bag case 2
Inlet and outlet respectively installation one temperature sensor（The first temperature sensor T1 in figure and second temperature sensor T2）.
Coal dust into cloth bag case 2 is deposited in cloth bag ash bucket 3, and 2 lower part of cloth bag case in figure is set there are two cloth bag ash bucket 3, Mei Gebu
A temperature sensor is installed on bag ash bucket（Third temperature sensor T3 in figure and the 4th temperature sensor T4）.Coal dust is from cloth
Bag ash bucket 3 enters pulverized coal bin 4 through lower coal valve group 6, reciprocating sieve 5, and the coal dust in figure in each cloth bag ash bucket 3 passes through two reciprocating sieves
5 enter pulverized coal bin 4, and a temperature sensor is installed on the coal unloading tube on 5 top of each reciprocating sieve（The 5th temperature sensing in figure
Device T5 and the 8th temperature sensor T8）.The data measured are transmitted to DCS by each temperature sensor（That is distribution control system）, DCS is aobvious
Show each point temperature and variation tendency.
When blast furnace coal powder preparation system normal operation, the temperature of each measurement point tends towards stability.Pass through detection, cloth bag case import
Temperature normals is 75 degree, and outlet temperature normal value is 70 degree, and cloth bag ash bucket normal temperature is 70 degree, and coal unloading tube normal temperature is
65 degree.Instantly when coal blockage, deviation between coal unloading tube temperature and cloth bag ash bucket temperature increases, and coal unloading tube temperature is close to ring
Border temperature, if DCS detects that above-mentioned phenomenon, automatic alert prompt shaking for the maintenance personal road coal unloading tube road
There are failures for dynamic sieve, should take treatment measures in time.
DCS only just determines whether, there are vibrating screen failure, to pass through inspection in blast furnace coal powder preparation system operational process
It surveys 2 out temperature of cloth bag case and may determine that whether blast furnace coal powder preparation system is in operating status.
