Abstract
The invention relates to a lime kiln and particularly relates to an automatic feeding method of the lime kiln. The automatic feeding method of the lime kiln comprises the following steps of: I, carrying out automatic previewing before the start of a winch; and II, carrying out automatic feeding to complete the feeding in the lime kiln and bring a trolley back to the initial position. Through the thorough feeding method, the normal operation of a feeding system is effectively ensured.
Description
Technical field
The present invention relates to the limestone kiln, relate in particular to the charging method in limestone kiln.
Background technology
Feeding system plays very crucial effect in sleeve kiln, now a lot of shaft furnaces skip charging system and kiln before raw material storing and transporting system, kiln knocked over plate valve and do not formed a complete Controlling System of cover, independent, manually control separately, have also by artificial loading, due to each system's self contained function, the work accident such as putty easily occurs and affect the equipment service efficiency in the frequent operation of up and down haul, and then affecting lime output.
For addressing this problem, we push up at kiln radar level gauge have been installed, and send request material loading signal, and in raw material storing and transporting system back, add weighing bucket, send 4 ~ 20mA signal enabling, stop the raw material storing and transporting system.Weighing bucket is poured raw material in hopper into, and windlass drives bunker lift and pushes up to kiln, and kiln is knocked over plate valve and opened, and raw material is added in kiln, stops the material loading signal until kiln top radar level gauge sends.We rely on interlocked control to complete material loading the independent system integration together.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and a kind of limestone kiln automatic charging method is provided.The present invention guarantees the normal operation of feeding system effectively by very perfect charging method.
For addressing the above problem, a kind of limestone kiln automatic charging method, it comprises the following steps:
Step 1, preliminary examination step before windlass starts;
A selects automatic preliminary examination;
B checks whether three scram button states are normal, otherwise forbids the elevator electric motor starting;
C if the B result is normal, checks that successively whether feeding cart is low spacing or high spacing whether lax with the windlass rope, if forbid the elevator electric motor starting;
D, no if the C result is, check that whether the feeding cart of windlass band is in the mid-way, if manual regulation elevator motor is to the kiln bottom position;
E checks dolly successively whether low spacing, and truck be sky, and whether kiln is knocked over plate valve and closed, and one of them is no, forbids the elevator electric motor starting;
F, successively check whether bell, Wingdale scale hooper valve close and within a certain period of time scale hooper whether fill with, whether Wingdale and revolving top at starting position, one of result is no, all forbids the elevator electric motor starting;
Whether G carries out once the complete material action of not being with, checks normally, and if not, and dolly is forbidden the elevator electric motor starting stopping in setting-up time;
F allows automatic charging;
Step 2, the automatic charging step; Utilize automatical feeding system to carry out material loading:
A, radar level gauge detect when in kiln, material level is less than set(ting)value, start the automatic charging step;
B checks in scale hooper whether material is arranged, if material is arranged, carries out c, if without material, checks after Vibration on Start-up feeding machine and charging system whether hopper is full, if full, stops carrying out c after oscillating feeder and charging system, if less than, carry out b1;
B1 stops material loading, gets back to check in hopper whether material is arranged;
C checks whether truck slack rope device place limit switch moves; If stop material loading and get back to check in dolly whether material is arranged; If not action continues to carry out;
D opens the Wingdale scale hooper; If fail to open, get back to b1;
E is according to setting-up time discharging in the dolly; If fail to realize discharging, get back to b1;
F closes the Wingdale scale hooper, and the Vibration on Start-up feeding machine is dosed to completely toward scale hooper simultaneously, if action failure is got back to b1;
G opens kiln and knocks over plate valve and put in place; If there is fault to get back to b1,
H starts windlass, and cooling fan starts operation, opens band-type brake, by the variable frequency control Accelerating running, if there is fault to get back to b1,
I, windlass enters high-speed cruising, makes trolley travelling to upper deceleration point position, kiln top, and windlass enters low cruise, if could not enter low cruise, by band-type brake, it is stopped, and gets back to b1;
J, it is spacing that moving of car is risen the position to kiln, and windlass stops, and windlass band-type brake automatic band-type brake, dolly are parked in kiln top; If fault is got back to b1;
K, the dolly discharging is complete, controls the windlass low cruise by frequency-variable controller, starts simultaneously the windlass fan, and the windlass band-type brake starts; If being arranged, fault gets back to b1;
L after windlass enters high-speed cruising, closes kiln and knocks over plate valve, and kiln is knocked over plate valve and closed and put in place, if fail to put in place, forbids that bell opens, and reports to the police, and gets back to b1;
Carry out simultaneously,
M, reinforced in the limestone kiln;
N, feeding cart returns starting position.
M in described step 2, reinforced comprising in the limestone kiln:
Whether m1 opens the limestone kiln bell, open by spacing demonstration bell and put in place, gets back to if not b1;
M2, Wingdale is discharged in the limestone kiln from kiln liftout bucket, by the spacing dolly of controlling in the tram discharging, if positional fault is got back to b1;
M3 controls by radar level gauge and feeds in raw material, and detects material level in kiln, reaches set(ting)value and stops feeding in raw material, if fault is got back to b1;
M4 completes in the limestone kiln reinforced.
N in described step 2, hopper return starting position and comprise:
N1, dolly reach the spacing position of low level at the bottom of kiln, and windlass is converted to low speed, and detects its low cruise by switch, if fail to be transformed into low speed, band-type brake starts, and stops dolly, gets back to b1,
N2, dolly arrives the bottom, and low spacing startup stops dolly, if hopper stops failure, gets back to b1;
N3, dolly stops, and completes the automatic charging step.
The present invention pushes up at kiln radar level gauge has been installed, and sends request material loading signal, and in raw material storing and transporting system back, adds weighing bucket, sends 4 ~ 20mA signal enabling, stops the raw material storing and transporting system.Weighing bucket is poured raw material in hopper into, and windlass drives bunker lift and pushes up to kiln, and kiln is knocked over plate valve and opened, and raw material is added in kiln, stops the material loading signal until kiln top radar level gauge sends.The present invention raw material accumulating, kiln before material loading and these independent system's meters of kiln flap valve and level gage claim to be in the same place, rely on chain control to realize material loading, perfect feeding system.Realized the fully automated of real meaning, feeding process need not manual operation, only needs to check have or not abnormal and report to the police.
