Description
Technical field
The disintegrating machine and the control method thereof that the present invention relates to a kind of electric screw-type adjusting play, belong to slag treatment field.
Background technology
Generally speaking, pneumatic transporting slag has two hang-ups: the one, and pipeline blockage, the 2nd, because improving greatly transporting velocity, slag granularity causes pipeline wearing and tearing sharply, can make follow-up Pneumatic conveying pipeline frequent jams, have a strong impact on the production safety of power plant and cause reduce equipment life.
Existing DGS-830 single roll crusher has come into operation for many years, and its feature is: discaling roll is monoblock cast, can improve the feeding ability of large clinker; Jaw is adjustable, and particle size after cracking is not more than 30mm; Particle size after cracking is thin, and sealing is better; Bearing block is dissection type, be convenient to discaling roll dismounting, and bearing lubrication is very convenient; The ability of slagging tap is large, goes out the quantity of slag and reaches 40t/h.Yet owing to often sneaking into the less foreign material such as hardness higher metal iron block in coal, these foreign material are not washed by coal handling system equipment, will sneak into burner hearth and fall into disintegrating machine, cause mucking machine stuck, cause being forced to blowing out banking fire maintenance.Because this fault rate is very frequent, on average will there is weekly 1 ~ 2 time fault in a disintegrating machine, to production, cause very large pressure.
Summary of the invention
For the problem of above-mentioned existence, the object of the present invention is to provide disintegrating machine and the control method thereof of a kind of electric screw-type adjusting play.
technical solution of the present invention

A control method for electric screw-type adjusting play disintegrating machine, comprises the following steps:
(a) jam inductor judges whether stall of roll shaft;
(b) when disintegrating machine is stuck, roll shaft stall, jam inductor sends stuck signal to electrical control cubicles, and electrical control cubicles is directly controlled motor forward/backward rotation, fixes a breakdown, and disintegrating machine normally moves;
(c) if fault do not get rid of yet, i.e. still stall of roll shaft, electrical control cubicles is sent and is adjusted gap order to control cabinet, controls electric threaded shaft forward, and then drive ceiling hold to retreat, jaw and roll shaft gap are increased, thereby large granular materials fall, roll shaft recovers to rotate, and fault is got rid of, and disintegrating machine normally moves;
(d) after fault is got rid of, electrical control cubicles is sent and is recovered order to control cabinet rapidly, controls electric threaded shaft reversion, and then drives ceiling hold to advance, and jaw and roll shaft gap are restored;
(e), when disintegrating machine is again stuck, repeat (b) (c) (d) step;
In described step (b), electrical control cubicles is controlled the command program of motor forward/backward rotation and is: motor is counter continues forward after circling; If disintegrating machine normally moves, this command program finishes, if disintegrating machine is still stuck, repeats this command program, and this command program is carried out three times at most.
The recovery order that in described step (d), electrical control cubicles is sent to control cabinet, jaw and roll shaft gap return to original setting value.
beneficial effect of the present invention:
1, the built-in PLC control chip of electrical control cubicles can be realized automation, saves manpower;
2, it is accurate that electric threaded shaft is adjusted gap, and response is quick, and electric threaded shaft support force is large;
3, adjust gap mode to compare with tradition, safe and reliable, dual anti-sticking.

Fig. 2 is control method flow chart of the present invention;
In figure:
1, broken outlet 2, control cabinet 3, electric threaded shaft 4, ceiling hold 5, jaw 6, connecting screw rod 7, boiler slag removal pond 8, slag bucket 9, roll shaft 10, jam inductor 11, disintegrating machine body 12, electrical control cubicles.
The specific embodiment
For technological means, character of innovation that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
The invention provides and a kind ofly solve the easily disintegrating machine of stuck, electric screw-type adjusting play that be difficult for to adjust of current single roll crusher, and its control method is provided.
The disintegrating machine of a kind of electric screw-type adjusting play as shown in Figure 1, comprise slag bucket 8, disintegrating machine body 11, jaw 5, connecting screw rod 6, roll shaft 9 and broken outlet 1, also comprise electric threaded shaft 3, leading screw ceiling hold 4, control cabinet 2, jam inductor 10 and electrical control cubicles 12, electric threaded shaft 3 is tiltedly put in the lower left corner of disintegrating machine body 11 outsides, the upper end face of electric threaded shaft 3 ceiling holds 4 contacts with the back side of jaw 5, electric threaded shaft 3 is connected with electrical control cubicles 12 by control cabinet 2, jaw 5 upper ends are hinged by connecting screw rod 6 and disintegrating machine body 11, roll shaft 9 is provided with jam inductor 10, roll shaft motor is connected with electrical control cubicles 12, electrical control cubicles 12 inside are provided with PLC control chip.
The control method of a kind of electric screw-type adjusting play disintegrating machine as shown in Figure 2, concrete control flow is as follows: in disintegrating machine running, once run into large granular materials, there is jam phenomenon, roll shaft 9 stalls, jam inductor 10 sends stuck signal to electrical control cubicles 12, electrical control cubicles 12 is sent rotating control command to motor, and motor is counter continues forward after circling; If disintegrating machine normally moves, this order finishes, if disintegrating machine is still stuck, repeats this order, and this order is carried out three times at most, if fault is got rid of, disintegrating machine recovers to run well; If fault is not got rid of yet, it is still stall of roll shaft 9,12 of electrical control cubicles are sent and are adjusted gap order to control cabinet 2, control electric threaded shaft 3 forwards, and then drive ceiling hold 4 to retreat, jaw 5 and roll shaft 9 gaps are increased, thereby large granular materials falls, roll shaft 9 recovers to rotate, and fault is got rid of, and disintegrating machine normally moves; After fault is got rid of, electrical control cubicles 12 is sent and is recovered order to control cabinet 2 rapidly, controls electric threaded shaft 3 reversions, and then drives ceiling hold 4 to advance, and makes jaw 5 and roll shaft 9 gaps return to original setting value.
