Description
Technical field
The utility model relates to metallurgy industry iron-smelting process belt transmission, relates in particular to the electric control system that is used for blast furnace granulated slag high angle belt conveyer transmission mechanism.
Background technology
Can constantly produce grain slag after the metallurgy industry blast furnace ironmaking is produced, grain slag transports away by belt.Usually the layout of belt is a level, even the inclination angle is arranged, the inclination angle also is very little, but in actual production, owing to be subjected to the restriction of territorial environment, some enterprises have no alternative but designing a belt that degree of tilt is very big aspect the slag charge conveying, and during production control, it is moving that this belt only designs patrilineal line of descent with only one son in each generation, and promptly a motor drags the belt operation, and uses soft initiator that motor is carried out reduced-voltage starting.The moving belt running condition of this patrilineal line of descent with only one son in each generation is also unstable, has many hidden danger.In case motor or soft initiator that this is unique break down, the grain slag that smelt to produce can not in time be carried, and is deposited on the belt, can make blast furnace be forced to put red slag, in addition cause stop, slow wind.Checking or changing needs to consume the plenty of time, influences the continuity that blast furnace is produced.And, also can cause severe contamination to site environment because the slag charge that smelting produces is a chemical waste.
In addition, because belt is a high spud angle, belt is in the climbing section, and transfer rate is fast, and all there is vibration in frame always.Especially belt below carrying roller is affected bigger, not only the carrying roller surface abrasion is serious, change frequent, and cause carrying roller stand bolt looseness easily even the stand incident that comes off takes place, injure the normal operation of belt, also will influence blast furnace production, also aggravate the wearing and tearing of belt coal tub and the vibration of belt simultaneously.Because it is few for a long time during the slag charge of carrying, it is real-time change, the load that is belt is unbalanced, and the design of existing load diminishes at load by maximum slag charge amount transfer designs, not at full capacity even uncharge the time, transmission speed is also very fast, has increased the transmission range of belt meaninglessly, has aggravated the wearing and tearing of belt and associated components, also cause a large amount of waste of electric energy, thereby increased great amount of cost.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides a kind of special electric control system at this type of blast furnace granulated slag high angle belt conveyer, this system can guarantee to produce the continuity of transporting with slag charge, and can adjust transmission speed according to load variations.
The technical scheme that its technical problem that solves the utility model adopts is: the two transmission electric control systems of blast furnace granulated slag high angle belt conveyer.It is made of subsystem commonly used and standby subsystem, subsystem commonly used contains frequency transformer and the motor commonly used that is connected with frequency transformer, standby subsystem contains soft initiator and the standby motor that is connected with soft initiator, and frequency transformer and soft initiator can switch between motor commonly used and standby motor by isolating switch.The master loop I that frequency transformer is connected with motor commonly used go up and soft initiator and master loop II that standby motor is connected on be respectively equipped with two switching isolating switchs, one lead is connected master loop I with master loop II, this lead at the tie point of two master loops all between two isolating switchs.
This pair of transmission electric control system comprises corresponding with motor commonly used and standby motor respectively 2# band brake apparatus and 1# band brake apparatus.Frequency transformer and soft initiator are switchably controlled the switching of 2# band brake apparatus and 1# band brake apparatus by isolating switch; Frequency transformer and soft initiator to the switching of motor commonly used and standby motor with the switching of 2# band brake apparatus and 1# band brake apparatus is carried out simultaneously.
From being respectively equipped with two switching isolating switchs on the master loop III of frequency transformer and the master loop IV, finish the switching of 2# band brake apparatus and 1# band brake apparatus from soft initiator.One lead is connected master loop III with master loop IV, this lead at the tie point of two master loops all between two isolating switchs.
The utility model changes the control of high angle belt conveyer Electrified Transmission into the control of soft initiator reduced-voltage starting and frequency transformer variable frequency regulating speed control dual system, compares with the former moving electric control system of belt patrilineal line of descent with only one son in each generation, has the following advantages:
One, when the frequency transformer variable frequency regulating speed control, can turn the transmission speed of belt automatically down after a little while, save a large amount of electric power resources at slag charge.
Two, the belt after the improvement is normally carrying out the while of guaranteeing to produce, its transmission V-bar is original 1/2, even 1/3, promptly in the identical time, the transmission range of belt reduced half or 2/3rds, also just can reduce the degree of wear of belt, prolong the work-ing life of belt, reduce the replacing number of times of belt, originally change once half a year, expectation now can arrive belt of a year and a half replacing, has saved cost.
Three, in circuit that frequency transformer is in parallel with the master loop of soft initiator, utilize isolating switch to select.The all corresponding two cover electric control systems of two motors can in time will controls another motor of guiding under the situation that certain motor breaks down in that electric control system is normal, make to produce to keep continuous.
