Abstract
The utility model discloses a strip breakage protective device of a silicon steel continuous annealing machine set, which is provided with a frame at an outlet of an annealing furnace; the frame is provided with a signal hole and is further provided with a pair of optoelectronic switch detectors; detection signals of the optoelectronic switch detectors are connected with an I/O module of a PLC (Programmable Logic Controller) and a strip breakage alarm displaying device of an operating room; an optoelectronic switch is taken as a hardware strip breakage protective system for detecting elements, so that the strip breakage information of strip steel can be quickly fed, and the halt response speed of an operating line after strip breakage can be well solved. When the machine set runs normally, the strip steel shields the signal hole, optoelectronic switch shades light and transmits a signal '1' to the PLC, and then a system judges that machine set is normal; and when the annealing furnace has strip breakage faults, the strip steel can not shield the signal hole, the light passes through the optoelectronic switch and transmits a signal 'o' to the PLC, then the system judges the machine set has the strip breakage faults, and the machine set can be controlled to stop according to a preset strip breakage processing program, thus avoiding a larger fault.
Description
Technical field
The utility model relates to metallurgy industry silicon steel continuous annealing machine set technology field, particularly a kind of silicon steel continuous annealing unit belt break protection device.Mainly be applicable to: whether broken belt of band steel is detected in the annealing furnace exit of silicon steel continuous annealing CA5 unit, and can in time feed back to shut down and handle.
Background technology
At present, silicon steel continuous annealing line CA5 unit desin speed reaches 150 meters/minute, and its middle part equipment layout as shown in Figure 1.Because the reason of supplied materials or equipment, in the production process during annealing furnace exit regular meeting broken belt takes place, be provided with broken belt in the electric control system and detect, its principle is to feed back according to the speed of bridle rolls and tensile to judge whether broken belt.When the speed of bridle rolls and tension force actual value and set(ting)value difference met or exceeded certain threshold value, system judged that broken belt has taken place annealing furnace.Because the bridle rolls motor needs the long time just can reach threshold value behind the unit broken belt; so service line is shut down response slowly; the steel band broken end is brought drying oven into through regular meeting; and drying oven wear the band producers to advance the stove operation; this moment must be flame-out drying oven; can advance the stove operation after stove district temperature dropped to room temperature from 600 degrees centigrade, thereby increase fault-time greatly.
The utility model content
The purpose of this utility model provides a kind of silicon steel continuous annealing unit belt break protection device simple in structure, easy to use; make its band steel behind the annealing furnace broken belt, can in time feed back broken belt information; and can not bring the steel band broken end into drying oven, thereby can avoid generation than major break down.
The purpose of this utility model is achieved through the following technical solutions:
The utility model is with the hardware broken belt protector system of optoelectronic switch as measuring element in the design and installation of the exit of annealing furnace; promptly framework is set in the exit of annealing furnace; have telltale hole on the framework; and being provided with a pair of optoelectronic switch detector, optoelectronic switch detector detection signal connects the I/O module of PLC and the broken belt alarm display device of operation room.Send when having detected the broken belt signal, the broken belt protector input can be fed back the broken belt information of band steel fast, cuts off the master reset condition automatically, and unit installs this technical scheme additional and solves the response speed that service line is shut down behind the broken belt well.
The detection signal of above-mentioned optoelectronic switch detector also tape cutter bypass exhibited light, tape cutter bypass button and the tape cutter protection of attended operation chamber drops into button.
The broken belt alarm display device of aforesaid operations chamber is an exhibited light.
Above-mentioned optoelectronic switch detector is selected the E32F-T3B1 detector for use, and power supply is selected the DC24V power supply for use.
The control principle of hardware broken belt protector system: when unit normally moved, steel band covered telltale hole, the optoelectronic switch shading, and feed signals " 1 " is given PLC, and it is normal that system is thought; Behind annealing furnace generation broken belt, steel band can not cover telltale hole, and optoelectronic switch leads to light, and feed signals " 0 " is given PLC, and system thinks that broken belt has taken place unit, can be according to the broken belt handling procedure control compressor emergency shutdown that presets.
The beneficial effects of the utility model:
The utility model is simple in structure, and cost is low, and is easy to use, protects effective.Before the broken belt protector system of this cover optoelectronic switch, behind the annealing furnace generation broken belt, the steel band broken end often will not be brought into drying oven on having.Producers' operation that will just can return to normal production through about 8 hours time.And after having gone up this broken belt protector system, through nearly 1 year trial run, it is fast that the back response of stopping takes place broken belt, and no flase alarm has guaranteed the ordinary production of unit greatly to have improved output well, has created considerable economic.Simultaneously, the broken belt protector system of this cover optoelectronic switch has obtained further promotion and application at two silicon steel CA9 and CA10 unit, and is respond well.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but embodiment should not be construed as restriction of the present utility model.
The represented implication of each label is among the figure: No. two bridle rollss of 1-(2#BR); The 2-annealing furnace; 3-optoelectronic switch detector; 4-band steel traffic direction; No. three bridle rollss of 5-(3#BR); The 6-coating machine; The 7-drying oven.
Consult Fig. 2, Fig. 3, the utility model is at annealing furnace 2 exit installation frames, and opens telltale hole on framework, installs a pair of optoelectronic switch detector 3 additional, allow the infrared light beam of optoelectronic switch detector 3 pass telltale hole, the detection signal of optoelectronic switch is delivered to the I/O module of PLC.At operation room broken belt alarm display lamp, tape cutter bypass exhibited light, tape cutter bypass button, tape cutter protection input button are installed, signal is delivered to the I/O module of PLC.
The several places that need explanation:
(1). the band steel has two welding punchings or band steel to have broken hole also can cause flase alarm.In order to prevent flase alarm, the broken belt time-delay is set in the PLC program, the broken belt delay time is 2 seconds, promptly still leads to light after 2 seconds when optoelectronic switch leads to light, shows that then broken belt rather than welding punching or broken hole have taken place the band steel.
(2). because need unit crawl feeding welding during tape splicing behind the band steel broken belt, so need the signal of broken belt protector bypass to satisfy the broken belt condition of master reset.
(3). the model of optoelectronic switch is: E32F-T3B1; Power supply is the power supply of DC24V.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.If of the present utility model these are revised and modification belongs to the scope of basic design of the present utility model or equivalent technologies, then the utility model also should comprise these changes and modification interior.
