Abstract
The utility model belongs to a constant-suction electric magnetic iron remover control device. The control device comprises a rectifier transformer (1), a three-phase full-controlled bridge rectifier circuit (2), a voltage transformer (3), an iron remover (4) and a fault display circuit (7). The control device is characterized in that the iron remover (4), a hall current transformer (5) and the three-phase full-controlled bridge rectifier circuit (2) are sequentially connected with one another in series; and the hall current transformer (5) is connected with an analog-digital conversion module (6), the analog-digital conversion module (6) is connected with a relay module (8) and a control module (10), and the control module (10) is connected with a metal detector (9) and a trigger signal driving circuit (11). The control device always keeps same suction, is not influenced by working time and temperatures, does not block the running of a belt, can be used for sucking ferromagnetic materials buried in ores or coal, and has a good working effect.
Description
Technical field
The utility model belongs to equipment for removing ferric ion, particularly a kind of constant suction electric magnetic iron remover control device.
Background technology
At present, the electric magnetic iron remover that domestic usefulness is used on ore and the coal conveyer belt at home adopts the constant voltage mode to power to electromagnet usually, the weak point of this mode is: when tramp iron separator is just started working, both electromagnet was when cold conditions, its exciting current is very big, suction is also just very big, and the bigger ore of iron-holder this moment can pick up, even through regular meeting the belt operation takes place to block; After tramp iron separator work a period of time (about more than 5 hours), inner steady the liter significantly of electromagnet improved, and its suction also descends greatly, and the ferromagnetic parts that is embedded in ore or the coal is inhaled not through regular meeting.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, a kind of working time and temperature effect of not being subjected to is provided, remain the constant suction electric magnetic iron remover control device of identical suction.
The technical scheme that the utility model technical solution problem adopts is: a kind of constant suction electric magnetic iron remover control device, comprise rectifier transformer, three-phase full-bridge controlled rectifier, voltage transformer, tramp iron separator and fault display circuit, it is characterized in that Hall current transformer of series connection between tramp iron separator and three-phase full-bridge controlled rectifier, the Hall current transformer is connected with analog-to-digital conversion module, analog-to-digital conversion module is connected with control module with relay module, and control module is connected with the triggering signal drive circuit with metal detector.
The beneficial effects of the utility model are: this utility model remains identical suction, is not subjected to working time and temperature effect, can not block the belt operation, can not inhale the ferromagnetic parts that is embedded in ore or the coal, good working effect.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Figure is the electrical principle schematic diagram of constant suction electric magnetic iron remover control device.
Among the figure: the 1-rectifier transformer; The 2-three-phase full-bridge controlled rectifier; The 3-voltage transformer; The 4-tramp iron separator; 5-Hall current transformer; The 6-analog-to-digital conversion module; The 7-fault display circuit; The 8-relay module; The 9-metal detector; The 10-control module; 11-triggering signal drive circuit.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of constant suction electric magnetic iron remover control device, comprise rectifier transformer 1, three-phase full-bridge controlled rectifier 2, voltage transformer 3, tramp iron separator 4 and fault display circuit 7, it is characterized in that Hall current transformer 5 of series connection between tramp iron separator 4 and three-phase full-bridge controlled rectifier 2, Hall current transformer 5 is connected with analog-to-digital conversion module 6, analog-to-digital conversion module 6 is connected with control module 10 with relay module 8, and control module 10 is connected with triggering signal drive circuit 11 with metal detector 9; Rectifier transformer 1 connects 380V power supply and three-phase full-bridge controlled rectifier 2, and three-phase full-bridge controlled rectifier 2 is connected with tramp iron separator 4, between voltage transformer 3 in parallel, voltage transformer 3 is connected with analog-to-digital conversion module 6; Fault display circuit 7 is connected with relay module 8.
Operation principle is: the excitation output current amplifies processing as the computing of carrying out that negative-feedback signal is delivered in the analog-to-digital conversion module 6 after the detection of Hall current transformer 5, the thyristor operating angle of the full control of three-phase bridge is changed, to reach the purpose of constant current and pressure regulation.
The course of work of the present utility model: tramp iron separator 4 standbies wait for the iron signal to pass to metal detector 9, receive to start tramp iron separator 4 work behind the signal: suction, separation, recovery, deironing, the work standby that finishes, wait for signal next time.
