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 limestone kiln, particularly relate to the charging method in limestone kiln.
Background technology
Feeding system plays very crucial effect in sleeve kiln, now the Controlling System that plate valve does not form complete set knocked over by a lot of shaft furnace skip charging system and kiln before raw material storing and transporting system, kiln, respective independent, Non-follow control, what have also leans on artificial loading, due to each system self contained function, in the frequent operation of upper and lower haul, easily there is the work accidents such as putty and affect equipment use efficiency, and then affecting lime production.
For addressing this problem, we have installed radar level gauge on kiln top, send request material loading signal, and after raw material storing and transporting system, add weighing bucket, send 4 ~ 20mA signal enabling, stop raw material storing and transporting system.Weighing bucket is poured into raw material in hopper, and windlass drives bunker lift to kiln top, and kiln is knocked over plate valve and opened, and is added in kiln by raw material, until kiln top radar level gauge sends stop material loading signal.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 provides a kind of limestone kiln automatic charging method.The present invention, by very perfect charging method, ensures the normal operation of feeding system effectively.
For solving the problem, a kind of limestone kiln automatic charging method, it comprises the following steps:
Step one, preliminary examination step before windlass starts;
A, selects automatic preliminary examination;
B, checks that whether three scram button states are normal, otherwise forbids elevator electric motor starting;
C, if B result is normal, checks whether whether feeding cart relax, if forbid elevator electric motor starting at low spacing or high spacing and windlass rope successively;
D, if C result is no, check that whether the feeding cart of windlass band is in mid-way, if so, manual regulation elevator motor is to kiln bottom position;
E, check that whether dolly is low spacing successively, and truck is empty, whether kiln is knocked over plate valve and is closed, and one of them is no, then forbid elevator electric motor starting;
F, check bell successively, whether Wingdale scale hooper valve closes and whether scale hooper fills with within a certain period of time, whether Wingdale and revolving top at starting position, and one of result is no, all forbids elevator electric motor starting;
G, performs and is not once completely with material action, checks whether normal, and if not, and dolly does not stop in setting-up time, forbids elevator electric motor starting;
F, allows automatic charging;
Step 2, automatic charging step; Automatical feeding system is utilized to carry out material loading:
A, when radar level gauge detects that in kiln, material level is less than set(ting)value, starts automatic charging step;
B, checks in scale hooper whether have material, if there is material, then carries out c, if without material, checks that whether hopper is full, if full, carry out c after stopping oscillating feeder and charging system after Vibration on Start-up feeding machine and charging system, if less than, then perform b1;
B1, stops material loading, gets back to and checks in hopper whether have material;
C, checks the whether action of truck slack rope device place limit switch; If so, stop material loading getting back to and check in dolly whether have material; If there is no action, then continue to perform;
D, opens Wingdale scale hooper; Open if fail, then get back to b1;
E, according to setting-up time toward discharging in dolly; Realize discharging if fail, then get back to b1;
F, closes Wingdale scale hooper, and Vibration on Start-up feeding machine is dosed to full toward scale hooper simultaneously, if action failure, then gets back to b1;
G, opens kiln and knocks over plate valve and put in place; If there is fault, get back to b1,
H, start windlass, cooling fan startup optimization, opens band-type brake, by variable frequency control Accelerating running, if there is fault, gets back to b1,
I, windlass enters high-speed cruising, and make deceleration point position on trolley travelling to kiln top, windlass enters low cruise, if could not enter low cruise, then makes it stop by band-type brake, and gets back to b1;
J, it is spacing that moving of car rises position to kiln, and windlass stops, windlass band-type brake automatic band-type brake, and dolly is parked in kiln top; If fault, then get back to b1;
K, dolly discharging is complete, controls windlass low cruise by frequency-variable controller, starts windlass fan simultaneously, and windlass band-type brake starts; If there is fault to get back to b1;
L, after windlass enters high-speed cruising, close kiln and knock over plate valve, kiln is knocked over plate valve closedown and is put in place, puts in place, forbid that bell is opened if fail, and reports to the police, gets back to b1;
Carry out simultaneously,
M, reinforced in limestone kiln;
N, feeding cart returns starting position.
M in described step 2, feeds in raw material in limestone kiln and comprises:
Whether m1, opens limestone kiln bell, opened and put in place, get back to b1 if not by spacing display bell;
M2, Wingdale is discharged in limestone kiln from kiln liftout bucket, by the spacing dolly that controls in tram discharging, if positional fault, gets back to b1;
M3, is controlled by radar level gauge reinforced, and detects material level in kiln, reaches set(ting)value and stops reinforced, if fault gets back to b1;
M4, completes in limestone kiln reinforced.
N in described step 2, hopper returns starting position and comprises:
N1, dolly reaches low level restraining position at the bottom of kiln, and windlass is converted to low speed, and detects its low cruise by switch, is transformed into low speed if fail, then band-type brake starts, and stops dolly, gets back to b1,
N2, dolly arrives bottom, low spacing startup, stops dolly, if hopper stops unsuccessfully, getting back to b1;
N3, dolly stops, and completes automatic charging step.
The present invention has installed radar level gauge on kiln top, sends request material loading signal, and after raw material storing and transporting system, adds weighing bucket, send 4 ~ 20mA signal enabling, stop raw material storing and transporting system.Weighing bucket is poured into raw material in hopper, and windlass drives bunker lift to kiln top, and kiln is knocked over plate valve and opened, and is added in kiln by raw material, until kiln top radar level gauge sends stop material loading signal.The present invention relies on chain control realization material loading together with material loading before raw material accumulating, kiln and these independent system meters of kiln flap valve and level gage are claimed, perfect feeding system.Achieve the fully automated of real meaning, feeding process, without the need to manual operation, only need check without exception and report to the police.
