Abstract
The invention discloses a travel action control method for a scraper of a hamming and rolling type large-particle breaking machine, which includes steps as follows: starting an oil pump motor, starting cycle timing after closing a switch SL of a cycle timer, enabling a normally-closed and normally-open contact of an output relay to act according to the set time while driving an electromagnetic valve to act simultaneously, driving the scraper to reciprocate circularly to discharge under action of pressure of an oil pump, and then feeding into the system for realizing breaking production after an auxiliary unit and a main unit are started. In the method, the cycle timer is used for controlling action of the electromagnetic valve of the oil pump, action control manner of the scraper is changed, contact limit switches are omitted, control cables between a control cabinet to the limit switches are reduced, and failure caused by the control cables can be eliminated thoroughly.
Description
Technical field
The present invention relates to the large grain of a kind of hammer roll-type disintegrating machine scraper stroke action control method, for scraping clearly crushing system material.
Background technology
At present in the large grain of hammer roll-type crusher system, scraper comes and goes action and haul distance is mainly to control auxiliary reclay adhesive or release by two contact limit switches that are arranged on scraper both sides, then signal to oil pump magnetic valve and open or close hydraulic circuit, thereby control scraper piston, come and go action.But this control mode because of breaker production scene operating mode complicated, dust is larger, corrosivity mixed material is more, moisture absorption is serious, causes insensitive, the easy damage of limit switch action, fault rate high, often parking maintenance.And this mechanical contact limit switch access times are limited, and maintenance cost is high, often affect process units long period continuous and steady operation, and indirect economic loss is large.
This control mode is after limit switch damages, and scraper does not recycle and comes and goes action, causes accumulation of material in crusher system, easily causes the overload of slave motor to be burnt, and causes device security accident.
Summary of the invention
For the deficiencies in the prior art part, the object of the invention is to eliminate above-mentioned shortcoming and the large grain of a kind of hammer roll-type disintegrating machine scraper stroke action control method is provided, the method is controlled simple, stroke is easy to adjust, security is good, failure rate is low, more saves than traditional control method investment, and reliability is higher.
The large grain of a roll-type disintegrating machine scraper stroke action control method, adopts the action of cycle timer timing control oil pump magnetic valve, and concrete operation step is as follows:
(1) by the circular wait set of time of cycle timer, be, the proal haul distance of scraper; By the do action set of time of cycle timer, it is the haul distance that scraper moves backward;
(2), in the circular wait time of cycle timer, in cycle timer control relay output normally-closed contact closure, cycle timer control relay output normally opened contact is opened;
(3), in the do action time of cycle timer, when cycle timer control relay output normally-closed contact is opened, cycle timer control relay output normally opened contact is closed;
(4), when relay output normally-closed contact is closed, oil pump magnetic valve Y1 opens, when relay output normally-closed contact is opened, oil pump magnetic valve Y1 is closed;
(5), when relay output normally opened contact is closed, oil pump magnetic valve Y2 opens; When relay output normally opened contact is opened, oil pump magnetic valve Y2 is closed;
(6), when oil pump magnetic valve Y1 opens, when oil pump magnetic valve Y2 is closed simultaneously, scraper travels forward under the effect of pressure fuel pump, when oil pump magnetic valve Y1 is closed, when oil pump magnetic valve Y2 opens simultaneously, scraper is motion backward under the effect of pressure fuel pump.
The present invention compared with prior art, has changed scraper action control mode, has cancelled contact limit switch, has reduced switch board to limit switch control cables, the fault that thoroughly elimination brings thus.Meanwhile, the scraper causing because of limit switch corrupted does not circulate and comes and goes action, and causes the accident that accumulation of material slave motor is burnt thoroughly to eliminate yet.
Accompanying drawing explanation
Fig. 1 hammers the large grain of roll-type disintegrating machine scraper stroke action control method schematic diagram into shape for invention improves;
In accompanying drawing: 1 oil pump control loop 2 slave control loop 3 host computer control loop 4 cycle timer 5 relay output normally-closed contact 6 relay output normally opened contact 7 oil pump magnetic valve Y1 8 oil pump magnetic valve Y2.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, before use, is set circular wait time and the do action time of cycle timer 4 according to scraper haul distance, and is the proal haul distance of scraper by the circular wait set of time of cycle timer 4; By the do action set of time of cycle timer 4, it is the haul distance that scraper moves backward;
In the circular wait time of cycle timer 4, in cycle timer 4 control relay output normally-closed contact 5 closures, cycle timer 4 control relay output normally opened contacts 6 are opened;
In the do action time of cycle timer 4, when cycle timer 4 control relay output normally-closed contacts 5 are opened, cycle timer 4 control relay output normally opened contact 6 closures;
When relay output normally-closed contact 5 is closed, oil pump magnetic valve Y17 opens.When relay output normally-closed contact 5 is opened, oil pump magnetic valve Y17 is closed;
When relay output normally opened contact 6 is closed, oil pump magnetic valve Y28 opens; When relay output normally opened contact 6 is opened, oil pump magnetic valve Y28 is closed;
When oil pump magnetic valve Y17 opens, when oil pump magnetic valve Y28 is closed simultaneously, scraper travels forward under the effect of pressure fuel pump, and when oil pump magnetic valve Y17 is closed, when oil pump magnetic valve Y28 opens simultaneously, scraper is motion backward under the effect of pressure fuel pump.
During use, first start the motor in oil pump control loop 1, then the switch of closed circulation timer 4, cycle timer 4 is started, cycle timer 4 is at circular wait time and do action cyclic switching between the time, and then control relay output normally-closed contact 5, relay output normally opened contact 6, and oil pump magnetic valve Y17 and oil pump magnetic valve Y28 open with closed according to the control law of above-mentioned setting, thereby realize the scraper back and forth movement that circulates under pressure fuel pump effect, scrape clearly material.
After slave control loop 2 and host computer control loop 3 starts, system broken production that can feed intake.
